Description

The invention relates to a locking or locking device for a wing system, in particular door system, ie a device which is adapted to hold at least one wing of the wing system in at least one predetermined opening position as a locking position and thus to prevent movement and in unlocking this at least one Release wings so that it can be moved again.

Numerous wing locks are known in the art.

Many work, depending on whether they lock or unlock a wing when energized, rest or Arbeitsstrom based. In the first case, the lock locks when energized and unlocked in the absence of energization. A well-known use escape route doors, which in an emergency, ie in the absence of electrical power supply, release an escape route and thus have to cancel a lock of the respective door leaf. In the second case, however, the lock unlocks when energized and locked in the absence of energization. A well-known use are security doors, which must be kept securely closed in an emergency. Such locks must therefore be supplied with electrical energy for a considerable period of time in order to lock or unlock the respective wing. This leads to an enormous expenditure of energy and thus to high energy costs.

The object of the invention is to provide a Flügelverriegelungs- or -feststellvorrichtung, which at least reduces the disadvantages of the prior art.

This object is solved by the subject matter of claim 1. Advantageous developments of the invention are specified in the subclaims.

A device according to the invention is set up to lock or determine a wing of a wing system in a predetermined opening position, ie to prevent it from moving. For this purpose, the device has a locking element and an element to be locked. The locking element is set in the locking position as one of two working positions to lock the locking member or to prevent a movement in the unlocked position as the other of the two working positions. In unlocking position, however, the locking element releases the element to be locked with respect to its movement. One of these two elements is operatively connected to the wing so that it is moved along with a movement of the wing of this. This one element may for example be attached to the wing. Alternatively, an operative connection for example with a slider is possible, which is an example of part of a slide linkage, with which a trained as a door swing wing of a swing door system is operatively connected as wing system in a known manner. The locking element is provided with a bistable electromagnet. The electromagnet has an element which is in permanent magnetic interaction with an armature such that the armature is held in a respective one of the two working positions, that is, for example in the locking position, by this one element with a predetermined holding force (magnetic). In one case, this element can be used as a permanent magnet be formed, wherein the armature is formed of magnetizable material. But it is equally possible that the armature is designed as a permanent magnet and said element is formed of magnetizable material. In both cases, no current is required to hold the armature in unlocked or locked position. The electromagnet also has a return mechanism which is adapted to apply to the armature a restoring force in the direction of the other of the two working positions, that is, for example, the unlocked position. The return mechanism thus acts counter to the effective direction of the magnetic retaining mechanism '. This has enormous advantages in terms of the energy requirement of the lock according to the invention. For this or additionally, the electromagnet has a coil arrangement. The coil arrangement can be supplied with current in accordance with a first switching mode, ie it reduces or even completely eliminates the holding force such that the restoring force is greater than a resulting residual holding force of the one element with respect to the armature. As a result, the electromagnet can no longer hold the armature against the force of the return mechanism, and the return mechanism moves the armature automatically from the respective one of the two working positions to the other working position and thus switches the device between the working positions. Ie. the current supply causes the armature to be moved away from the associated working position counter to the effect of the respectively opposing magnetic counter-element. With this arrangement, a very simple and effective electromagnet is formed, which can safely hold the armature without energization in the aforementioned two working positions and thus formed bistable. The locking or locking element is adapted to be used in a fixed position in such a door system stationary. This makes it possible to integrate the lock in any door system having a rail.

Preferably, the coil assembly according to a logically second, opposite switching mode is energized such that it exerts on the armature a force sufficient to move this against the restoring force in the respective of the two working positions (back). Ie. In this case, the current supply causes the armature to be moved in the direction of the magnetic counter element. Ie. the return mechanism is realized or at least supported by this energization.

Preferably, the armature between the aforementioned two working positions along a predetermined path of movement is further preferably translationally movable. This simplifies the structure of the lock to the effect that no additional force or movement deflections are necessary to bring the armature in locked or unlocked position. This allows the use, for example, single-leaf, manually operated sliding sash systems such as sliding window systems, folding door systems, partitions and the like.

The other, ie to be locked or (self) locking element is preferably arranged to be inserted into the same or another rail in or along and thus guided by this. This is on the one hand a safe operation of the lock possible. In addition, these elements of the latch, apart from the mutual locking engagement, do not have to meet any other criteria regarding their travel or stability. The path of movement of the element to be locked or locked is thus defined and ensured by the associated profile rail. If the profile rail runs straight, the element to be locked or locked is translationally movable.

The lock may further comprise a holding part to which the aforementioned stationary insertable element is fixedly mounted. Further includes they are a clamping part, wherein the clamping part and holding part receive the stationary insertable element between them and form two halves of a housing of the stationary insertable element. This provides mechanical protection and possibly protection against contamination of this element. In addition, it can be freed from stability tasks and optimized for the locking function.

The lock preferably has clamping means, by means of which the stationary insertable element is clamped in the rail via the clamping or holding part. The deadlock has the advantage of being able to fix the stationary element at any position in the rail without having to edit the rail. This allows in particular a very simple retrofitting and adjustability of existing systems with regard to the installation position of the lock in the rail and thus the opening position of the or the associated wings, in which the lock locks the wing or the.

The clamping means advantageously comprise at least one screw which is supported on a first inner surface of the profile rail. It is also screwed to the clamping or holding part such that the clamping or holding part is pressed during rotation of the screw in a Verklemm-direction of rotation against a second inner surface of the rail, that the stationary element is clamped in the rail. D. h the clamping action is effected by the screw presses with one end against the first inner surface of the profile part and the thus screwed clamping or holding part is pressed against a corresponding second inner surface of the rail and thereby clamped.

The lock according to the invention is preferably further configured to release the element to be locked when the lock on a Force acting against the retaining means of the locking element, which is greater than a predetermined maximum holding force of the locking element. Ie. the lock allows the violent unlocking of the relevant wing and thus has an overload protection that helps prevent damage to the wing system or the lock itself.

The latch according to the invention preferably further comprises a self-sufficient power supply, which is electrically coupled to the locking element. This allows a lock that does not require an externally connected power supply. This is made possible, in particular, by the fact that the device requires energy, preferably exclusively in the form of a short-time switching pulse, exclusively for the period of switching between the aforementioned working positions; in the working positions themselves, no external energy supply is necessary. Thus, for example, a pure battery operation with a very long duration is possible. This minimizes the wiring effort, for example with a building cabling, which helps reduce costs. The lock can also be used wherever there is (still) no external power supply. In addition, a simple retrofitting is possible, especially if the rail is sold as part of the locking device with.

The power supply is preferably also set up to be used fixedly in one, preferably the same, rail. Ie. in extreme cases, the entire lock can be used as a compact unit in a single rail. Only the coupling with a locking control, for example in the form of an emergency opening switch still has to be made. Ie. during assembly, there is only a single part, namely the rail, drilled for the mounting holes if necessary Need to become. Alternatively, the rail must not be edited, namely, if it is glued, for example, on a support body as a door frame.

Preferably, the power supply is fixed to the stationary insertable element. Thus, the power supply itself must be designed only to be used in the rail, but not necessarily locked in this self. This is done via the stationary insertable part. Thus, the power supply may be formed, for example, as a simple battery pack, which is glued to the stationary element, for example.

The locking element preferably has a plunger which extends away from the armature and the electromagnet substantially along the path of movement and, in the locked position, brings at least one locking part of the locking element into a position in which the at least one locking part engages with a corresponding locking part of the locking element Element is in lock engageable or stands. Ie. not the anchor but an operatively connected locking member causes the lock. This makes it possible to optimize the armature or plunger with respect to the locking part and the magnetic interaction with the coil assembly and the magnet out. Stability criteria with respect to the locking engagement with the element to be locked are not or hardly observed.

The plunger preferably comprises two rod sections. One of the two bar sections is operatively connected to the armature such that its movement is transferred to that one bar section. It is also guided on or in the other rod portion relative to this movable. Ie. the movement or current position of the anchor does not in all circumstances cause the locking effect to occur. It is possible, despite the locking position of the armature to effect a (forced) unlocking. For this purpose, the rod section remote from the armature runs pointedly at its end facing away from the armature. The latch further includes a return member configured to urge the rod-removed portion toward the tapered end. With this arrangement, when moving the armature by way of example in the locked position normally both bar sections are also moved into the locked position. If an excessively high force is exerted on the locking element to be locked and currently locked away from the locking element, so that damage to the Verrieglungung or wing system are to be feared, the locking part of the locking element on the locking part of the locking element, the armature remote rod portion in Press in the direction of the armature and thus release the locking effect, even though the armature remains in the locked position. In addition, it can be realized that the part to be locked from a non-engaging position with the locking element, so its locking part, despite locking position of the armature with the lock can be brought into locking engagement.

Each rod section preferably has a stop in each case. Between the thus two relatively movable stops is used as a restoring element biased a compression spring. This is a particularly easy way to realize the overload function.

The locking element advantageously further has a limit to the movement of the rod sections relative to one another. This serves for operational safety, since the rod sections can only move in a predefined manner which does not impair operation.

The at least one locking part of the locking element can be formed by means of a pivoting arm. The pivot arm is pivoted due to the tapered end of the armature remote rod portion upon movement of this rod portion in the direction of pivot arm in the locking position. It has at its end remote from its pivot axis on a locking portion which is in locking position with the corresponding locking portion of the locked element in locking engagement. This is a particularly simple and powerful very effective solution for overload-protected locking. The swivel arm facing, thus acting as a starting slope surface said rod portion causes an adaptable to the particular application force transmission between the magnetic holding force of the magnet with respect to the armature and the locking member.

The aforementioned profile rail may be formed as a slide rail of a slide linkage. It can also be designed as a support, (floor) guide and / or support rail of the relevant wing or wing system or include these. Ie. Despite the locking forces to be applied, the lock can be made so compact or with such small dimensions that it can be used in almost any rail.

According to the invention, the electromagnet can have a plurality of mutually independent coils or windings, depending on how the interlocking device according to the invention is to be operated. Ie. the coils or windings can be arranged and formed in accordance with the desired mode of operation of the latch. This allows, for example, a redundant and thus fail-safe operation of the electromagnet and thus the device of the invention as a whole by one or more Coil / n or winding / s is or are available as a replacement for one / several other coil (s) or winding (s). Additionally or alternatively, depending on the application, different locking or unlocking forces can be generated or adjusted on the electromagnet, which increases the possible uses of the device. The device is thus universally applicable; Less trained, standardized electromagnets are possible in training, which helps reduce costs. In addition, it is thereby possible to achieve a mode of operation, for example including Vorlastüberwindung.

Suitable, provided with such a locking wing systems are in particular all sliding sash systems such as sliding door, Schiebefenster-, partition walls and further revolving door systems with movable drum walls and swing door systems preferably with Gleitgestänge. Ie. the lock can also be used on a door without slide linkage by the lock is fastened with a holder as a rail on the aforementioned support body such as a door frame, wall or the like. In this case, the holder rail allows a visually favorable, preferably hidden mounting of the lock.

FIG. 1 a shows a latch 100 according to a first embodiment of the invention in the locked position. The latch 100 includes a detent 110 and an electromagnet 120.

The solenoid 120 is bistable. For this purpose, the electromagnet 120 at two opposite and facing away from each other side armature 121, 122. The anchors 121, 122 are formed of magnetizable material. If the solenoid 120 or its coil arrangement 127, not shown here, is energized, the right armature 121 or according to a second switching mode, the left armature 122 is electromagnetically attracted by the electromagnet and thus to the left or to the right in FIG FIG. 1 a moves. The solenoid 120 serves as an end stop for the armature 121, 122 and thus limits their movement.

The anchors 121, 122 are fixedly mounted on a rod portion 123 or integrally formed therewith, which passes through the electromagnet 120. In the example shown, the right armature 121 is fixed by means of a fastening screw 126 on the rod portion 123. This allows the rod portion 123 with anchor 122 in the assembly from the left in FIG. 1 a pushed through the electromagnet 120 thereafter and then provided at the right end here with the armature 121 and the fastening screw 126. With this arrangement, when one of the armatures 121, 122 is attracted by the solenoid 120, the other armature 122, 121, respectively, is moved away from the solenoid 120.

The electromagnet 120 preferably has a permanent magnet (not shown) inside. The permanent magnet is arranged in such a way that the armature 121, 122 respectively resting on the electromagnet 120 is held in the current position by the permanent magnet. The magnetic holding force between the permanent magnet and the armature 121, 122 which is currently in contact with the electromagnet enables the electromagnet 120 not to be energized in order to magnetically hold the adjacent armature 121, 122. This also means that when the electromagnet 120 is energized, it exerts a force, preferably as an attraction force on the currently non-adjacent armature 122, 121, which is greater than the magnetic holding force of the permanent magnet with respect to the currently applied armature 121, 122.

The rod section 123 passes through the armature 122 and, on its side of the armature 122 facing away from the electromagnet 120, additionally has a spring stop 123a here in the form of a disk which is preferably circular in cross section. At the end of the spring stop 123a remote from the magnet 120, a guide section 123b adjoins.

The guide portion 123b has a guide groove extending along the direction of movement of the rod portion 123 and the armatures 121, 122, respectively. In the electromagnet 120 remote from the end of the rod portion 123, a second rod portion 124 is inserted. The rod portion 124 has a guide pin 124b which extends transversely to the direction of movement or longitudinal extent of the rod portion 124 and the guide groove 123b engages in this guided.

The guide groove 123b is preferably not continuous in the direction of movement of the guide pin 124b. As a result, the guide pin 124b, and thus the rod portion 124, can only move along a limited path with respect to the rod portion 123. Ie. this type of guide portion 123b forms a movement limit for the guide pin 124b and thus for the rod portions 123, 124 relative to each other.

On the rod portion 124, a spring stop 124a is further formed or arranged. A spring 125 is inserted between the spring stops 123a, 124 preferably biased. It acts as a restoring element and forces the rod sections 123, 124 apart, so that in an extreme case the guide pin 124b bears against the end of the guide groove facing away from the electromagnet 120.

In the example shown, the rod section 123 also extends through a clamping part 130. The clamping part 130 and an associated holding part 150 form a receiving or cavity 1 between them, in which the rod sections 123, 124, including the return spring 125, are arranged or received in a freely movable manner. The clamping part 130 and the holding part 150 are formed so that they are inserted into a rail 10 can. The rail 10 is in the example shown, the slide for a sliding rod based door operator, so door closer or door drive.

The clamping member 130 has a clamping portion 132 which rests against an inner surface of the profile rail 10, which is not described here in detail. In the clamping portion 132, two clamping screws 131 are screwed, of which only one is visible here. Their function will be described later.

At the end remote from the electromagnet 120 of the rod portion 123, the locking member 110 is arranged. It comprises two pivot arms 112, of which only one is visible here. Each pivot arm 112 has, at its end facing away from the electromagnet 120, a roller 111 whose axis of rotation extends substantially perpendicular to a longitudinal extent of the profile rail 10. Furthermore, in the region of the end of the rod section 123 facing away from the electromagnet 120, each pivot arm 112 has a different roller 113 whose axis of rotation preferably runs parallel to the axis of rotation of the roller 111. The function of the rollers 111, 113 will also be explained later.

FIG. 1b shows the latch 100 of FIG. 1 a in unlocked position. As can be clearly seen, the armatures 121, 122 and, connected thereto, the bar sections 123, 124 are moved to the right such that now the right armature 121 abuts against the electromagnet 120. The end of the rod portion 124 facing away from the electromagnet 120 is preferably formed as a tip 124c.

Figure 1c shows the holding part 150 in greater detail. It has, at the end not shown here detent 110 facing away from a terminal portion 152, which is used to wire the locking 100, not shown. In this case, the connection portion 152 preferably forms a receptacle for a terminal block 30. The terminal block 30 here comprises a circuit board 31. This is preferably inserted by clamping with two opposite, unspecified side edges in corresponding grooves 153 of the holding part 150. A connection terminal part 32 of the connection block 30 is fastened here on a side of the circuit board 31 facing away from the electromagnet 120. The connection terminal part 32 comprises by way of example two connection terminals 33 for clamping two lines, not shown. From the side facing the electromagnet 120 side of the board 31 go here accordingly two connecting leads 34 in the direction of electromagnet 120 and thus couple the terminal block 30 with the electromagnet 120. To lay the lines 34, the holding part 150 preferably has a cable guide here in the form of two parallel to each other extending projections 154 on. The projections 154 thus include a groove-like recess in which the lines 34 are preferably laid by clamping. The protrusions 154 can thus prevent the lines 34 from rubbing against the profile rail 10, for example when they are inserted, and possibly being damaged.

Finally, fastening screws 128 are shown, by means of which the electromagnet 120 is fastened to the holding part 150.

Figure 1d shows the arrangement of Figure 1c diagonally from above FIG. 1 c. Each terminal 33 comprises a screw 35, by means of which the respective outgoing to the right and not shown line can be coupled to the associated terminal 33. Of course, all other types of terminals are possible. Further, in the solenoid 120, the passage is for the one not shown Rod section 123 in the form of a continuous, in cross-section by way of example circular through opening 120a to recognize. The passage opening 120a preferably has a constant inner diameter or constant internal dimensions throughout and extends along the path of movement of the rod section 123 in the electromagnet 120.

FIG. 2 shows a lock 100 according to a second embodiment of the invention also in both unlock and in the locked position.

It differs from the previous embodiment in the design of the electromagnet 120 in connection with the rod portion 123.

As can be seen, there is only one extra trained anchor 121 here; the function between armature 121 and solenoid 120 remains. The armature 121 is preferably in turn attached by means of a screw 126 to the rod portion 123. The electromagnet 120 has a passage which does not have a constant inner diameter or inner dimensions throughout and extends along the path of movement of the rod portion 123 in the electromagnet 120. It is divided along its longitudinal extent into three sections 120b-d. The first section 120b, which faces the armature 121, has the smallest inner dimensions or the smallest inner diameter. At the end facing away from the armature 121 of this portion 120b, a second section 120c connects, which has an inner diameter increasing away from the armature 121. Ie. the inner dimensions become larger and larger in the direction away from the armature 121 and thus extend the passage through the electromagnet 120. At the end of the partial section facing away from the partial section 120b 120 ° C is followed by a third passage portion 120d having inner dimensions, which are preferably equal to the maximum inner dimensions of the portion 120c.

In the region of the passage created by means of the subsections 120b-d, the rod section 123 has an outer contour that is substantially complementary thereto. The passage and the rod portion 123 are also preferably designed to be slippery in these areas, so that the rod portion 123 is received guided in the passage with low friction.

A portion 123c of the rod portion 123 corresponding to the portion 120b and slidably received therein has a length substantially equal to a sum of the length of the portion 123a and the maximum travel of the rod portion 123 with respect to the solenoid 120.

Subsections 123d, 123e of the rod section 123 adjoining the section 123c in the direction away from the armature 121 are slidably received in the respective corresponding section 120c or 120d and designed to be substantially complementary thereto. Ie. the partial section 123d tapers in the direction of the partial section 123c. Thus, the portion 123d and the armature 121 in conjunction with the solenoid 120 and its passage define a limit to the movement of the rod portion 123 with respect to the solenoid 120, thus defining the maximum possible distance of the armature 121 from the solenoid 120.

The subsection 123e corresponds in construction to the corresponding part of the rod section 123 according to the first embodiment the invention. Ie. Again, there is a spring stop 123a, on which the return spring 125 is supported on the right side. Further, there is a second return spring 123f, which is preferably inserted biased between the solenoid 120 and the spring stop 123a. Ie. the return spring 123f urges the rod portion 123 to the left via the spring stopper 123a FIG. 2 away from the electromagnet 120. The magnetic holding force of the electromagnet 120 with respect to the portion 123d is so large that the return spring 123f alone is unable to lift this portion 123d from the electromagnet 120.

At least the portion 123d is formed of magnetizable material. If the electromagnet 120 is energized accordingly, in a first scenario according to the first switching mode the armature 121 is electromagnetically attracted by the electromagnet 120 and the partial section 123d lifted off from the electromagnet 120 due to the supporting action of the return spring 123f and to the left in the locking position according to FIG FIG. 2a emotional. Due to this mode of operation, the portion 123d functionally forms the armature 122 according to the first embodiment of the invention. Therefore, at least the portion 123d of the rod portion 123 is formed of magnetizable material.

If the armature 121 is in a second scenario according to the second switching mode again in the in FIG. 2b shown position, that is brought in unlocking position, the solenoid 120 is energized so that now the portion 120 d and not the armature 121 is attracted electromagnetically by the electromagnet 120. This electromagnetic attraction force is greater than the sum of the restoring force of the spring 123f and the magnetic holding force of the electromagnet 120 with respect to the armature 121, so that the armature 121 securely engages the in FIG. 2a shown position is moved. Ie. Again, a bistable solenoid is formed, in which the solenoid 120 must be energized only to change the working position.

The other structure with respect to rod portion 124 and locking member 110 corresponds to the structure according to the first embodiment of the invention.

Figure 2c shows the lock 100 without clamping part 130, and Figure 2d without holding part 150. Figure 2d in particular serves to illustrate the locking action between the locking part 110 and a slider 140, for example, a door leaf slide linkage.

The pivot arms 112 or their rollers 111 are adapted to engage with a slider 140, for example, a sliding linkage in locking engagement, so the slider 140 to take so that it can not be moved in the not shown here for reasons of representation rail 10. The slider 140 includes a mounting portion 141 which serves to attach and thus connect a non-illustrated linkage arm of said slide linkage. Further, the slider 140 includes two sliding surfaces 142, with which the slider 140 is slidably guided in the guide rail 10 sliding translationally guided.

The slider 140 is formed in the example shown by means of a cross-sectionally C-shaped retaining profile 147, which thus has two mutually parallel legs 148 with free ends.

On outer sides of the legs 148, the sliding surfaces 142 are exemplified in the form of sliding coatings or mounted or arranged. The slider 140 is preferably rotationally symmetrical, so that it does not matter with which end face it faces the locking part 110. Each leg 148 has on the inside, preferably in both frontal areas of the slider 140 each have a locking portion 143. The locking portion 143 comprises for each pivot arm 112 corresponding to at least one projection 144 and adjoining thereto in the direction of connection portion 141 recess 149. In locking position, the pivot arms 112 engage with their free ends, ie here with their rollers 111, in said recesses 149, such as in Figure 2d shown.

In order to allow the pivot arms 112 to overcome the projections 144 with as little friction as possible, the rollers 111 are provided. In addition, the projections 144 are formed so that they have in the direction of locking part 110 run-up slopes 146 which run apart in the direction of locking part 110. On the side facing away from the locking part 110, the projections 144 also have run-on slopes 145 which, viewed in the direction of longitudinal extension or movement of the section from the locking part 110, run steeper apart than the run-on slopes 146. This causes the pivot arms 112, when inserted into the recesses 149 intervene, more difficult, d. H. under higher force, can be moved out of the locked position than into this.

In the respective pivot arm 112, an axis 114 is preferably used, on which the associated roller 113 is arranged freely rotatable. The axles 114 may also be formed integrally with the respective pivot arm 112.

As can also be seen, pivot axes 133 are used in the clamping part 130, on which the pivot arms 112 freely rotatable or pivotable are arranged. The pivot pins 133, which are designed as bearing pins, can also be formed in one piece with the clamping part 130.

Further, bearing pins 134 are inserted into the clamping member 130 to allow attachment of a cover plate, not shown. The cover plate preferably has both for the bearing pins 134 and for the pivot axes 133 receptacles or through holes into which the respective axis 133 and the respective bearing pin 134 preferably engage by clamping. This results in a very easy to install, yet very stable arrangement.

Furthermore, the clamping part 130 has a screw portion 135, in which 131 through openings 135a are formed for receiving clamping screws. Their effect will be explained later. Finally, fixing screws 128 can be seen, by means of which the electromagnet 120 is fastened to the holding part 150.

As indicated above, the slider 140 is in Figure 2d with the locking member 100 and the pivot arms 112 and thus the rollers 111 in locking engagement. Ie. the rollers 111 engage in the respective associated recess or in the respective associated locking portion 143 of the slider 140 a. Furthermore, the bearing pins 133 can be seen, on which the pivot arms 112 are freely rotatable or pivotally mounted. In a central region, the pivot arms 112 bear with mutually facing sides on the rod portion 124, which consequently acts as a plunger and presses the pivot arms 112 in the locking position in the recesses 149.

The rollers 113 serve as a friction reduction between the pivot arms 112 and the rod portion 124, so that this relatively low friction can move past the pivot arms 112 in the direction of locking member 110. The rollers 113 are arranged for this purpose on the pivot arms 112 in contact areas with the rod portion 124 freely rotatable, and their running surfaces are in the locking position on the rod portion 124 at.

The spring stop 124a is integrally formed on the rod portion 124 in the example shown. The same applies to the spring stop 123a with respect to the rod portion 123. Between the spring stops 123a, 124a, the return spring 125 is arranged.

By way of example, the clamping part 130 has, on the end facing the electromagnet 120, the aforementioned screw section 135 with screw openings 135a. In the screw holes 135a, the clamping screws 131 are screwed. Each screw 131 has at its end, not shown holding part 150 facing each end a support portion or a support surface 131 a.

The rod portion 124 preferably has a pointed end 124c at its end facing the electromagnet 120. With this tip 124c, it is possible for the rod portion 124 to pivot and push apart upon movement on the pivot arms 112 to over the rollers 113.

Advantageously, the rollers 113 are in the locking position continue to sides of the tapered end 124c of the rod portion 124 at. If the slider 140 were forced away from the locking part 110 due to an unintentional movement on the door leaf, the locking device 100 could be damaged if the force is excessively high. To avoid this, the rod portion 124 against the action of the return spring 125 with respect to the rod portion 123 to be pushed toward the solenoid 120. This is done by means of the above-mentioned starting bevels 145 of the slider 140. If the slider 140 is urged away from the locking member 110 with a correspondingly large force, the locking force in the form of the disengaging force of the rod portion 124 is overcome with respect to the pivot arms 112. The protrusions 144 of the slider 140 are gradually moved past the pivot arms 112. The free ends of the swivel arms 112 are pivoted relative to one another via the rollers 111 via the run-on slopes 145 which move past the swivel arms 112 and come closer to each other during this movement. The rollers 113 press against the tip 124c in such a way that they and thus the rod portion 124 are urged away from the pivot arms 112 in the direction of the electromagnet 120.

The permanent magnetic holding force of the electromagnet 120 is sufficient to securely hold the armature 121 against the return spring force of the spring 125, so that the rod portion 123 does not change its position here. Since the rod portion 124 is received in the rod portion 123 freely movable guided, thus, only this can be right in FIG. 2 are moved so that the armature 121 is not released from the electromagnet 120. The return spring 125 is thereby stretched (further). Once the pivot arms 112 have overcome the projections 144, they diverge along the chamfers 146, so that the distance between the rollers 113 increases again. This results in an ever-increasing propriety between the rollers 113, in which the rod portion 124 is pushed back due to the force of the prestressed return spring 125. The slider 140 is thus released from the lock and thus unlocked. This realization represents a very simple and effective overload protection for the latch 100.

If the slider 140 in this position in the direction of locking member 110 (back) moves so that the rollers 113 come into contact with the chamfers 146, the rollers 113 are pushed together again upon sliding of the slider 140 and the rod portion 124 via the tip 124 c back in Direction solenoid 120 moves.

The chamfers 146 include with the direction of movement of the rod portion 124 in this area preferably a smaller acute angle than the chamfers 145, reduce their distance from one another so less and thus are less steep. This allows the pivot arms 112 and their rollers 111 in this scenario, the projections 144 reach with less force and then overcome. Ie. the relevant door can be forcibly locked with less force than forced unlocked.

After overcoming the projections 144, the pivot arms 112 reach the area of the recesses 143. As the force for compressing the pivot arms 112 decreases, the return spring 125 (supportive) can again push apart the pivot arms 112 via the tip 124c, thereby entraining the rollers 111 engage the locking portions 143, so that the slider 140 is securely locked again, although the solenoid 120 with respect to the armature 121 has never lost the locking effect.

FIG. 3 shows the arrangement of the latch 100 shown here in detail in the rail 10. The fixation of the lock 100 in the rail 10 is carried out by way of example exclusively by means of the clamping screws 131 in connection with the clamping member 130th FIG. 3a is the clamping member 130 in a state in which it is indeed inserted into the rail 10 but not yet fixed therein.

In the in FIGS. 3b and c shown position, it is fixed in the rail 10.

Im in FIG. 3a As shown, the preferably two clamping screws 131 are arranged so that the clamping member 130 can be moved freely here in the leaf level or out of her and to some extent down in the rail 10. The through-openings 135a, which are not visible here, are each provided with an internal thread through which a respective clamping screw 131 with its screw head 131b is screwed on or through. Ie. Screw 131 and its head 131 b preferably has a non-illustrated male threaded portion throughout. Each screw 131 continues in the direction away from the clamping part 130 away in a support portion 131 a, with its front side, in FIG. 3a upwardly facing surface 131 c comes to lie on a respective corresponding inner surface 11 of the rail 10.

The clamping part 130 also has support or clamping surfaces 130d, which by means of only in FIG. 3b designated Eckausnehmungen 130c are formed and facing away from the support surfaces 131 c in the example shown. If the clamping screws 131 are rotated in the clamping direction, ie according to FIG. 3a upward, the clamp member 130 is moved downward. At some point, the downwardly facing surfaces 130d of the Eckausnehmungen 130c of the clamping member 130 to be located on corresponding inner surfaces 12 of the rail 10, as in FIG. 3b shown. Upon further rotation of the clamping screws 131, the clamping part 130 and the clamping screws 131 are clamped as a whole arrangement in the rail 10 and thus fixed.

Advantageously, the clamping part 130 also has guide surfaces 130e, which slide along corresponding, facing them inner surfaces 13 of the rail 10 along and thus complicate tilting of the clamping member 130 in the rail 10 at least. The clamping part 130 has, on its side facing the support sections 131 a, by way of example in the center, preferably a recess 130 b, which makes it possible to take up the restoring spring 125, not shown here, in a space-saving manner.

The screw heads 131 b are due to the cross-sectionally C-shaped rail 10 at any time accessible from the outside, according to Figure 3a and 3b from below and according to Figure 3c from above. Thereby, the clamping member 130 can be locked in any position in the rail 10 and released and thus used without any other processing of the rail 10 at the respectively desired position in the rail stationary.

Figure 3c shows the lock 100 in the context of the holding part 150, the clamping part 130 and the clamping screws 131, fixedly inserted into the rail 10. As can be seen, the holding part 150 and the clamping part 130 in. In FIG. 3b shown state a predetermined distance from each other. The holding part 150 preferably comprises side sections in the form of continuous or partially interrupted projections 151, of which only the left one is visible and which are guided in corresponding guide grooves 15 of the profile rail 10. This insertion and extraction of the latch 100 are made easier from the rail 10 and tilting in the longitudinal direction of the rail 10 at least difficult.

Of course, a clamping screw 131 is sufficient; However, two facilitate the protection against the possible tilting of the holding part 150 in the rail 10 in the vertical direction in FIG. 3 ,

FIG. 4a shows a latch 100 according to a third embodiment of the invention. The entire lock 100 is again received in a rail 10, and that stationary. It can be seen, the pivot arms 112 and solenoid 120 and return spring 125. Furthermore, in the example shown, a non-bistable solenoid 120 'is arranged and deactivated. The solenoid 120 'is part of an existing latch, which is used for cost reasons.

The electromagnet 120 is inserted in the profile rail 10 by way of example between fixing parts 20. The armature 122 is inserted between the electromagnets 120, 120 'and, with appropriate energization of the electromagnet 120' from this to the left in FIG. 4a attracted and possibly moved. This movement is transmitted to rod portion 124 via rod portion 123, which is indicated here. The pivot arms 112 or their rollers 111 are set up, again with a slider 140 to engage in locking engagement, ie the slider 140 to be taken so that it can not be moved in the rail 10. By way of example, the slider 140 again comprises the attachment or connection section 141. Only one of the sliding surfaces 142 is visible.

The armature 121 is disposed between the electromagnet 120 and the left fixing part 20 here.

FIG. 4b shows the latch 100 in the locked position, and Figure 4c in unlocked position.

In the example shown, the electromagnet 120 'is designed to be resting or working current-based and deactivated. This embodiment is advantageous if a classic lock is already present as a module and due to the existing locking elements and mounting option in the rail 10 should continue to be used.

The latch 100 is extended by the bistable solenoid 120. The anchors 121, 122 are connected to each other via a connecting element 129 and are located on two opposite end faces of the electromagnet 120th D. h. the solenoid 120 may be energized to electromagnetically attract the armature 121 or 122 according to the first and second switching modes, respectively. The electromagnet 120 is in the profile rail 10, not shown, by means of him in FIGS. 4b, c Locking part 20 arranged on the right locked. The electromagnet 120 is attached to this fixing part 20. Alternatively, the fixing part 20 is part of the electromagnet 120. In addition, another fixing part 20 can be arranged on the left side, thus limiting the path of movement of the armature 122 away from the electromagnet 120.

Preferably, the fixing parts 20 are formed in two parts. They include a holding part 21 and a relatively movable clamping plate 22. the clamping is preferably carried out by means of clamping screws 23rd

FIG. 4b shows the latch 100 in the unlocked position. In this state, the armatures 121, 122 are displaced to the left, the armature 122 preferably rests against the left-hand fixing part 20.

Figure 4c shows the jamming of the fixing member 20 in the rail 10 in a sectional view transversely to the longitudinal extent of the rail 10 through the clamping screws 23 therethrough. The holding part 21 has for the clamping screws 23 screw holes 21 b, so openings or holes with internal thread, on. The screws 23 are screwed by way of example by means of their heads 23a in the holding part 21. Ie. the screw heads 23a each have an external thread.

In the assembled state clamping surfaces 21 a of the clamping member 21 are pressed against corresponding inner surfaces 11 of the rail 10, of which only the right is designated. In contrast, clamping surfaces 22a of the clamping plate 22 are pressed against corresponding inner surfaces 14 of the rail 10. Thus, holding member 21 and clamping plate 22 can be pressed apart, the clamping screws 23 at its clamping plate 22 end facing support portions 23b here in the form of tapered sections which pass through the clamping plate 22 through through holes 21 c of the clamping plate 21 therethrough.

Alternatively, the clamping screws 23 are simply in abutment with their upwardly pointing ends as support sections 23b on the clamping plate 22. Ie. by twisting the screws 23 holding part 21 and clamping plate 22 are moved apart or away from each other or towards each other and thus either clamped in the rail 10 or released from it.

The clamping screw 22 are advantageously in turn freely accessible due to the C-shaped cross section of the rail 10, so that the fixing member 20 can be solved at any time of the rail 10.

FIG. 5a shows a latch 100 according to a fourth embodiment of the invention. As can be seen, there is only one armature 121 here. The armature 121 is urged away from the electromagnet 120 by means of the return spring 123f. The force of the example as a compression spring formed return spring 123f is less than the magnetic holding force of the electromagnet 120 with respect to the armature 121 applied to it, when the coil assembly 127 of the electromagnet 120 is not energized. When the electromagnet 120 is energized, the armature 121 is either electromagnetically attracted to the locked position by the electromagnet 120 according to the energization direction, or repelled away from the electromagnet 120 according to the second switching mode, so that the lock 100 is safely unlocked.

Alternatively, when the electromagnet 120 is energized according to the second switching mode, the holding force with respect to the armature 121 abutted against the electromagnet 120 is canceled out in such an order that the resulting residual holding force of the electromagnet 120 with respect to the adjacent armature 121 is less than the restoring force of the spring 123f is. As a result, the spring 123f is able to secure the armature 121 to the left in FIG FIG. 5a to move and thus the lock 100 to unlock safely.

Figure 5b to Figure 5d show variations of the in FIG. 5a by means of a dashed line delimited section of the latch 100 in greater detail.

According to FIG. 5b the rod portion 123 on the right side of the solenoid 120 is provided with a stopper disc 123g. The stop disc 123g is fixed to the rod portion 123, for example by means of pressing, gluing, welding or the like. The outer dimensions of the stopper plate 123g are such that they can not move through the through hole 120a. Thus define the distances of the armature 121 and the stop plate 123g from the electromagnet 120, the maximum movement path of the rod portion 123 with respect to the electromagnet 120 and its coil arrangement 127th

Alternatively, the stopper disc 123g is an integral part of the rod portion 123.

In addition, the rod portion 123 on the right side of the stopper disc 123g may have the same outer contour as the stopper disc 123g itself. The rod portion 123 thus receives a step-like abutment, as already described with respect to FIG FIG. 2 described.

According to the sectional view in FIG FIG. 5c the above-described stop is formed by means of a snap ring 123h, which is fixedly inserted into an unspecified groove of the rod portion 123 and prevents excessive movement of the rod portion 123 to the left.

According to the sectional view in FIG FIG. 5d In turn, the stop is formed by means of a stop disc 123g, which is screwed onto the rod portion 123. Advantageously, the stop disc 123g is formed as a nut, which can be easily attached by means of a wrench.

FIG. 6 shows a modification of the embodiment of FIG. 5 , Here, two anchors 121, 122 are formed, which are connected to each other via the rod portion 123. The electromagnet 120 here has a coil arrangement 127 with two coils 127a, 127b as an example. The energization of the left according to the first switching mode or according to the second switching mode right coil 127a and 127b results in the respectively nearest armature 121 or 122 is attracted electromagnetically.

The right armature 122 is preferably urged by a spring biased return spring 123f of the latch 100 toward the solenoid 120. The magnetic holding force of the electromagnet 120 with respect to the armatures 121, 122, d. H. without Spulenbestromung, is sufficient to hold the respective armature 121, 122 on the electromagnet 120. The current is supplied so that only the coil 127a, 127b is energized, from which the respective armature 121, 122 is spaced. Ie. the coil 127a, 127b, at the end face of the armature 121 and 122 is present, is not energized. Therefore, for each coil 127a, 127b, there is the same electromagnetic energization in a classical manner for attracting the respective armature 121, 122. This results in a bistable electromagnet which is very simple to construct and operate.

In summary, it should be stated that in the context of the invention an bistable electromagnet is present through an arrangement of permanent-magnetic material and electromagnet 120 or coil arrangement 127. The respective armature 121, 122 is held by the permanent magnetic material by way of example in the form of a permanent magnet. A short-term energization of a respective coil 127a, 127b or coil arrangement 127 with a corresponding current direction leads to a brief suspension of the magnetic holding force of the armature 121, 122 preferably retained on the electromagnet 120 and preferably simultaneously to the electromagnetic attraction of the other armature 122, 121 122 attracted by the electromagnet 120, the rod portion 124 are moved away from the pivot arms 112 and released in their pivoting. Thus, after switching to unlocking despite a lack of continuous energization a safe unlocking position reached. However, if the armature 122 is due to a return mechanism 'in the form of electromagnetic attraction of the armature 121 from the electromagnet 120, a return spring 123f and / or other equally acting means, the rod portion 124 to the pivot arms 112 out of these moves away from each other and spread apart, which are thereby largely locked in their pivoting in the direction of unlocking position. Thus, after switching to the locked position, in turn, despite the lack of continuous energization, a secure locking position is achieved.

Figure 7a shows the latch 100 of FIG. 6 in section and with a modified electromagnet 120. The armature 121 and the spring 125 are partially shown. The electromagnet 120 includes, by way of example, two electro-coils 120e, 120f which preferably can be energized independently of one another. The coils 120e, 120f are shown in section and only in part and optically separated from each other by unfilled circles (coil 120e) and by black circles (coil 120f). As can be seen, individual, unspecified windings of the coils 120e, 120f alternate in the horizontal direction. As a result, when in each case only one of the coils 120e, 120f is energized, a magnetic field which is similar in each case to the spatial propagation can be generated, in particular if the coils 120e, 120f have conductors with identical cross section and identical number of turns.

The exemplary two coils 120e, 120f allow two or even three different strong magnetic fields. If only one of the coils 120e, 120f is supplied with identical electrical energy in each case, the generated magnetic field strength depends on the windings of the respectively energized coil 120e, 210f and the conductor cross-section of the respective coil winding. Additionally or alternatively, the winding numbers and / or conductor cross sections of the coils 120e, 120f may differ from each other, as in FIG FIG. 7d indicated and explained later.

Alternatively, by means of such a coil arrangement, a pulsating magnetic field can be generated. Pulsed magnetic fields have the advantage of being able to move the armature 121 out of the respective position even when preloaded. Such a preload may arise, for example, when a user presses a connected door in the opening direction, whereby, although not shown, the pivot arms 112 are pressed against the bar portion 124 or, if present, its tip 124c. This increases the friction between pivot arms 112 and rod portion 124, which the electromagnet 120 must overcome when moving the armature 121. In particular, this pulsation lends itself to bar sections 124 without tip 124c.

The pulsing can be done by alternately energizing the coils 120e, 120f, as long as they generate magnetic fields of different magnitudes.

Alternatively or in alternation, both coils 120e, 120f can be switched on and off at the same time, whereby the respective pulse is amplified.

Again alternatively or in contrast to one of the aforementioned modes of operation, only one of the coils 120e, 120f can be pulsed on and off, while the other coil 120f, 120e remains permanently switched off or is energized. In the latter case, a basic magnetic field strength arises, which is increased in a pulsating manner.

As an alternative to the aforementioned operating modes, it may be provided to use only one of the coils 120e, 120f and to use the other coil 120f, 210e only in the event of failure. Ie. it is a redundant coil arrangement. This increases the reliability of the electromagnet 120.

FIG. 7b shows another arrangement again two coils 120e, 120f. As can be seen, the coils 120e, 120f are arranged one behind the other from the perspective of the armature 121. As a result, the magnetic field strengths of the individual coils 120e, 120f generated in the electromagnet 120 can be varied. In addition, this allows coils 120e, 120f to be used as separately available coils in a modular manner in the electromagnet 120. There is no separate winding of the solenoid 120 to provide, which helps reduce costs. In addition, this allows the use of standardized or already available on the market coils.

FIG. 7c again shows another arrangement of two coils 120e, 120f. As can be seen, the coils 120e, 120f are arranged above or next to one another from the perspective of the armature 121. The inner coil 120e may serve as a support for the coil 120f. This arrangement also makes it possible to use coils 120e, 120f as separately available coils in the electromagnet 120. This coil arrangement is particularly suitable for the aforementioned redundancy training.

As already in relation to Figure 7a 1, the conductor cross sections of the windings of the coils 120e, 120f may be different from each other as in FIG FIG. 7d shown. Exemplary for the coil arrangement according to Figure 7a As shown, the conductor of the coil 120e has a larger cross section than the conductor of the coil 120f. Ie. the coil 120e tolerates a higher current or a higher voltage than the coil 120f, whereby it can be achieved that the coils 120e, 20f produce different strength magnetic fields, combined with the aforementioned advantages.

The invention is not limited to the above-described embodiments.

Although the invention has been described in connection with a slide rail as a profile rail 10, the latch 100 can be applied to any type of door system in which there is a rail, for example in the form of a receiving or guiding profile; in the present example in a straight running rail. Ie. For this purpose, in particular all types of sliding sash systems are suitable, wherein for example on a carriage of one of the sliding sash an element to be locked can be arranged, which can be locked by means of the bistable electromagnet 120.

Instead of two locking pivot arms 112, which are pressed by means of the rod portion 124 against corresponding locking recesses 149, this can also be done otherwise. For example, the pivot arms 112 may have locking recesses into which corresponding locking projections of, for example, the slider 140 engage.

The slider 140 may for example also be designed as a floor slider, for example, a sliding leaf and attached to the respective sliding sash.

Furthermore, instead of two, there may also be only one or more pivot arms 112, which are arranged, for example, about an axis which runs parallel to the longitudinal extension of the rod section 124. in the In the case of a swivel arm 112, the rod section 124 is preferably guided on the side facing away from the swivel arm 112, for example along the profile rail 10.

Instead of the pivot arms 112, it is also possible to provide pure, preferably overload-protected latching connections in order to achieve the locking effect.

The latch 100 may also be configured to lock multiple doors. In the case of classic double-leaf sliding doors or telescopic sliding doors, in which at least two door leaves are actively connected with each other via a traction mechanism drive, the other (lock) would automatically lock when one door leaf locks.

Alternatively, each wing has its own latch 100 which are interconnected such that a switching pulse of a controller, such as a switch, leads to a simultaneous switching of the plurality of locking devices 100. In the simplest case, the electromagnets 120, for example, two latches 100 are electrically connected in parallel.

The lock 100 can also be designed without overload protection. In the embodiments described above, in the simplest case, the pointed end 124 c is omitted, so that the pivot arms 112 abut against opposite, parallel to the path of movement of the rod portion 124 extending surfaces. In this case, the rod sections 123, 124 are advantageously formed in one piece, and the return spring 125 including spring stops 123a, 124a can be dispensed with, which simplifies the construction.

Further, in the rail 10, a second solenoid 120 may be used, which is used for example by means of the above-described clamping parts 20 in the rail 10. The armature 121 is inserted between the electromagnets 120 and thus is moved between the locking and the unlocking position, depending on the energization of the left or right electromagnet 120 or its coil arrangement (s) 127. Thus, only one anchor 121, 122 is required.

At the in FIG. 4 In this case, the electromagnet 120 'can remain activated. The armature 121 including connecting element 129 is preferably eliminated. To reach the unlocking position, preferably only the electromagnet 120 'is energized so that it electromagnetically attracts the armature 122. In support of the solenoid 120 can be energized, electromagnetically repel the armature 122 or at least partially cancel the magnetic holding force between armature 122 and solenoid 120. To reach the locking position, in turn, only the electromagnet 120 is preferably energized so that it electromagnetically attracts the armature 122. In support of the solenoid 120 'can be energized, electromagnetically repel the armature 122 or at least partially cancel the magnetic holding force between armature 122 and solenoid 120. Ie. the electromagnets 120, 120 'are simple electromagnets, which again form a bistable electromagnet with the armature 122.

The respective armature 121, 122 may also be formed as a permanent magnet. Thus, electromagnets 120 can be used, which themselves have no permanent magnets. Advantageously, the coils 127a, 127b are wound on cores of magnetizable material, which are formed or arranged so that they enter with the respective armature 121, 122 in the above-described magnetic interaction.

In the FIG. 2 illustrated embodiment may be modified such that the sections 120 b and 123 e are interchanged with the sections 120 d and 123 c, so that they are in FIG. 2 now right or left side of the associated portion 120b, 123d are arranged.

Again alternatively, the armature 121 is also replaced by partial section 120b and 120d, 123e.

Instead of a continuously integrally formed rod portion 123 this can also be made in several parts. These several parts are fastened to each other, for example, by means of pressing, jamming, screwing or the like together. This allows in particular the training shown in the previous section, for example, by two parts of the rod portion 123 from the right and left in FIG. 2 inserted into the through hole and fastened together when pushed together, for example by means of screwing together.

Also, the frustoconical shape of the sections 120c, 123d is only exemplary. It is any other type of dimensional change, for example by means of a gradation, so that the sections 120c, 123d completely eliminated, possible, provided that the magnetic interaction according to the invention is achieved. However, the truncated cone increases the magnetic interaction area between the electromagnet 120 and the rod portion 123 or the portion 123d, so that the amount of permanent magnetic material can be kept small.

The clamping screws 131 may alternatively or additionally be screwed in Hatteteil 150.

Instead, by means of the fastening screw 126, the armature 121 may be secured to the rod portion 123 by any other attachment such as jamming, gluing, latching and the like. The same applies to the fastening screws 128 with regard to the electromagnet 120 and / or the fastening of the fixing part 20 to the electromagnet 120.

The run-on slopes 145, 146 may, but need not be flat. They may, for example, be concave or convex, depending on which force transmission between run-on slope 145, 146 and tip 124c is desired.

Instead of a separate armature 121 and the spring stop 123b can take over the function of the armature 121, which further simplifies the structure.

The rod portion 123 may be replaced by or combined with the connector 129.

Each armature 121, 122 may preferably be spring loaded in the direction away from the solenoid 120, respectively.

The respective terminal member portion 32 may include more or less than two terminals 33, depending on Verschaltungsaufwand. As a result, other elements such as sensors and the like can be coupled to the outside world.

The latch 100 may also include a plurality of terminal blocks 30. For example, it may at each end of the holding part 150 depending on a terminal block 30 with different numbers of terminals 33 have. This makes it possible to loop through cables.

The parts 30, 120, 128, 131, 133, 134 may be attached to the clamping part 130 all or partly instead of the holding part 150.

In addition, the lock or its arrangement with clamping part 130 and holding part 150 can be slidably inserted in the rail 10, whereas the element to be locked, such as the aforementioned slider 140, is arranged in the rail 10 stationary.

The solenoid 120 may have any number of coils 120e, 120f instead of two. Alone FIG. 7 arrangements shown can be used for all of the above-described operations. The arrangements can also be combined with each other. For example, it may be provided, each coil 120e, 120f according to FIG. 7b each by a coil arrangement according to Figure 7a to replace. Ie. For example, the right and left coils 120e, 210f would again consist of two coils. This allows for a combination of the use of different magnetic field strengths with the advantage of redundancy. The different cross-sectional choice according to FIG. 7d can be applied to all other coils 120e, 120f. In addition, these winding arrangements can be applied to any of the above-described electromagnets 120, 120 '.

Of course, the latch 100 can also be integrated into known, multi-leaf door systems as part of a closing sequence control, in particular if this interacts with slides of sliding linkages.
