DE10246643A1 - Electro-mechanical lock for cupboard doors has provision to indicate when door is not properly locked - Google Patents

Abstract

To latch a door (1) a pushbutton (13) is depressed. This rotates a plate (20) about a pivot (24) which pushes the latch bolt (6) into the carcass (11) and an electromagnetically driven interlock (2) moves forward engaging in the hook section (28) of the plate to secure the latch bolt. If the door has not been properly latched a spring (26) reverses the plate, the interlock cannot engage and the push button moves to position (13) indicating that the door is not locked.

Description

The invention relates to a lock with protection against incorrect operation according to the preamble of claim 1. In particular the invention a lock with an electrically operated lock, wherein the actual sliding drive for the locking bolt by finger pressure he follows.

Such locks are preferred for closet systems in fitness centers, pools and staff rooms used. They are preferred with an encoded data card to open and close. As a rule, the lock is locked by one door leaf sweeping button is pushed against a corresponding actuating spring by finger pressure, being with the inward facing To press the actuation button the locking bolt in its closed position is moved into the associated recess in the body.

Another type of actuation is that one at the actuating button rotates the locking bolt also against the force of an actuating spring to move into the assigned recess in the body.

With the manual actuation of the locking bolt Finger press on the actuation button the user is led to believe that the lock is actually already is in the locked position. After being an electronic one Lock, the electronic locking system for the locking bolt must also be used take effect to finally lock the lock.

A well-known lock system sees No action against such incorrect operation (missing, final Locking). presses for example, a sports bag from the interior of the cabinet the door, then the locking bolt is clamped in its locking recess in the body and the user receives mechanical closing using the actuation button the wrong impression that the lock is actually (finally) locked is. There are also no warnings or display elements, which let the user know that the electrical locking system is still is not working.

In another known lock system the locking bar is turned into its locking position by turning the actuation button brought. The user can now mistakenly assume that the electrical Locking system is already engaged because of the lock indeed by pulling the actuation button in the opening direction no longer open is. However, the locking bolt can be turned by turning the operating button easily in its open position brought, which the user usually does not tried more. For this reason, incorrect operation occurs because the user mistakenly assumes that the lock is final is locked.

The final lock on the known, second lock system would only take place if that you have a corresponding data card on the actuation button the electronic control system activates the locking bolt holds with a corresponding solenoid in its locked position.

The user refrains from pressing the actuation button with his data card, then the lock is supposedly locked, is not against reopening protected.

The object of the invention is therefore to further develop a lock of the type mentioned at the beginning, that it's more reliable is secured against the incorrect operation mentioned at the beginning.

To achieve the object, the invention is characterized in that
With the given technical teaching there is the essential advantage that an immediate actuation of the displacement path of the pawl by the actuation button - as is the case with the prior art - is now dispensed with. Instead, according to the invention, a deflection element is arranged in the displacement path between the locking bar and the actuation button, the pivoting of which can be blocked by the locking element actuated by an electric drive.

In a preferred embodiment the pivoting of the deflection element is spring-loaded, so that this always in the open position is pivoted and the associated actuation button also in its open position shifts.

Now is the lock according to the invention be closed, then the actuation button is pressed with a finger applied which leads to a displacement movement of the actuation button, the in turn, the deflecting element is pivoted into its closed position.

The other, swiveling part of the Deflection element is in contact with the locking bolt, see above that it is in its closed position in the assigned closing recess is indented in the body.

While the manual operation the actuation button is the electrical sliding drive for the locking element still out of engagement with the deflecting element.

If the incorrect actuation mentioned at the beginning occurs where, for example, a heavy object holds the bolt in the Body recess stuck because the door has the appropriate weight in the open position depressed incorrect operation does not occur.

Thanks to the fact that the deflecting element lies with its free pivotable part on the locking bar, but is pivoted into the open position with a spring, the deflecting element disengages from the clamped locking bar and moves the actuation button back into its open position under the load of this spring , It is visually visible to the user that he did press the actuation button, but that it comes out again under spring load and thus makes it visually visible that the closing process was not successful.

Even if the user is now at pushed out actuation button tried over his data card the electrically operated locking element to operate does this to no closure because the locking element on the outer circumference of the pivoted Deflection element strikes and thus a final one there is no electronic locking.

The actuation button is at a such misoperation in its open position far beyond that Front of the door protrude and form a corresponding signal for the user, that the door not properly closed has been.

With a correct closing process becomes the operation button again in the manner described above in the recess in the Pushed in door and the deflecting element is actuated the locking bolt in the closing direction, so that this into the closing recess engages in the body.

In this pivoted position of the Deflecting element, which occurs against the spring load of the spring, can now by a corresponding data card, which is from the outside to the actuating button is created, the electronic control system is informed that the lock is now in the mechanical locked position and by actuation of the electrical displacement drive for the locking element the final closure or Securing this mechanical closure.

An incorrect operation in the beginning mentioned type is therefore definitely excluded.

The deflecting element is essentially formed as a two-armed lever, one being pivotable Share the operation button and arranged in the other pivotable part of the locking latch that can be moved into its locked position.

Instead of a pivoted one, spring-loaded deflection element can therefore also be a simple two-armed Lever are used, which is also in a lever position is pivoted spring-loaded. Instead of swiveling, a Deflection element selected be moved between the two end positions.

Should - in a different embodiment - instead of one printing operation the actuation button a rotary switch chosen then the previously mentioned measures apply analogously. It is only essential according to the invention that between the actuation button and the locking bolt arranged a spring-loaded transmission element which is the rotation or displacement movement of the actuation key picks up and passes on to the locking bolt. In the shifting or The path of rotation of this deflection element must then be that of the electrical displacement drive actuated Locking element can intervene.

So the invention is not on a pivotally mounted deflection element is limited, but refers also on displaceable or on rotatably mounted deflection elements, which a corresponding pivoting movement by rotating the Actuation key - instead a shift - accomplish.

It is important in the invention that in principle the displacement path of the actuation button is locked, when the lock is in the locked position. This means, even if the electrically operated locking element in closing engagement with the deflecting element. In this way it is always ensured that the outside visible closed position is only effectively achieved when the actuation button is in the pressed state in the recess in the door is otherwise pushed out by the spring load on the deflecting element becomes.

The subject of the present invention arises not only from the subject of the individual claims, but also from the combination of the individual claims.

All in the documentation, including the Summary disclosed information and features, especially the spatial training shown in the drawings claimed as essential to the invention, insofar as they are used individually or in Combination versus the state of the art are new.

The invention is described below of just one way of execution illustrative drawings explained. Here go from the drawings and their description essential features and advantages of the invention.

In 1 is on a door 12 a carrier housing 1 attached, in the interior of which the lock system according to the invention is arranged.

Through a recess in the door 12 grabs an actuation button 13 , thus, by their position 13 in the position 13 ' in the direction of the arrow 14 and is designed to be displaceable in the opposite direction.

The in 4 locking bolt shown is in a recess 5 in the housing 6 in the direction of the arrows 3 . 4 slidably mounted.

On one surface 7 the locking bolt 6 lies one part 31 a rotatably mounted deflection element 20 on whose other rotatable part 32 with assigned approaches 16 . 17 the actuation button 13 connected is.

In the 1 position shown is the locking bolt 6 with his tie 9 in an assigned recess 10 in the body 11 indented, but a final, secure closed position has not yet been reached because the locking element is driven by an electrical, mechanical or electromagnetic drive (not shown in more detail) 2 not yet in locking engagement with the pivotable deflection element 20 is.

The deflecting element 20 according to the 5 and 6 has two opposite pivot bearings 24 with which it can be swiveled into the carrier housing 1 is stored. A spring is supported here 26 (here designed as leg spring) with one part on the carrier housing 1 off while the other part of the spring 26 itself on a cone 25 of the deflecting element 20 supports, which is thus clockwise (in the direction of the arrow 27 ) is pivotable.

The storage of the actuation button 13 on the swiveling part 32 of the deflecting element 20 is done by using opposite approaches 16 . 17 on the actuation button 13 aligned holes 18 are arranged, and between the approaches 16 . 17 a space 19 is trained. In this space 19 engages the deflection element 20 a, the opposite and aligned with each other on the deflecting element 20 arranged spigot 23 rotatable in the holes 18 intervention.

The deflecting element 20 is approximately segment-shaped and is made of a swivel plate 22 formed, at one end a hook 28 is arranged.

The locking bolt 6 otherwise has an approach 8th on which a spring, not shown, acts on the locking bolt with its bolt 9 in the open position from the recess 10 in the body 11 withdraws.

It comes to the in 1 misoperation shown, namely the actuation button 13 in the opposite direction to the arrow direction 14 has been pressed in, then the deflecting element 20 around its pivot point 24 in the opposite direction to the arrow direction 27 pivoted and the part 31 moves the lock bolt 6 outward so that the latch 9 in locking engagement with the recess 10 in the door 11 arrives. The door is now supposedly locked (but not electromechanically!).

Thanks to the spring-loaded deflection element 20 but presses the spring 26 the deflecting element 20 around its pivot point 24 in the direction of the arrow 27 back so that the operation button 13 in the direction of the arrow 14 out of the recess 15 in the door and in the carrier housing 1 is pushed out and the position 13 ' occupies. The user now knows that when the push button protrudes 13 ' there is an incorrect operation or the door is in the open position or unsecured closed position.

In this position, the electrically operated locking element can not 2 in locking engagement with the deflecting element 20 come because of the catch 29 at the front free end of the locking element 2 on the outer circumference of the part 31 of the deflecting element. The actuation button 13 therefore remains in the position 13 ' ,

Only when the user makes a new attempt and manually press the actuation key 13 presses and at the same time the card near the front of the actuation button 13 the corresponding control is activated.

For the rest, it is provided that to protect the power supply at the approach 17 the actuation button 13 an actuation flag 30 attaches that actuates a switch, not shown, on the control circuit board. With this switch, the entire control system is "awakened" and only then is the power supply to the control system released.

Only when this power supply is switched on can you get near the front of the actuation button 13 brought data card cause the electric drive of the locking element 2 to start and this in the direction of the arrow 3 in locking engagement with the deflecting element 20 bring to. Here the hook reaches behind 29 of the locking element 2 the assigned hook 28 on the deflecting element 20 so that these two parts are securely engaged. So that the deflecting element 20 in its closed position against the force of the spring 26 held and the lock bolt 6 is also held in its closed position. This leads to a stable mechanical locking without the displacement drive of the locking element 2 still plays a role.

The actuation button 13 does according to the rest 1 a slight panning motion because of the approaches 16 . 17 on the swiveling part 32 of the deflecting element 20 attack. So a slight tilting movement is caused. To guide the actuation button 13 in the recess 15 is therefore a management area 21 on one side of the actuation button 13 arranged to secure them against rotation and to ensure longitudinal guidance.

To open the lock, either with the touch of a finger or with the data card itself on the front of the actuation button 13 pressed that by a small displacement even further over their in 1 position shown in the recess 15 can be pressed so that the operating flag 30 actuated the aforementioned switch on the control board.

The control is "awakened" and with that already on the front of the actuation button 13 attached data card is thus the sliding drive for the locking element 2 acts and moves this in the direction of the arrow 4 backwards so the two hooks 28 . 29 disengage and the deflecting element 20 again under the weight of the spring 26 pivoted into its open position. This will be the locking bolt 6 released and with the force of the return spring attached to the approach 8th the locking bolt is applied 6 moved to its open position.

Moreover, it is not necessary to press the actuation button with the finger to bring about the closure 13 presses and at the same time the data card near the actuation key 13 brings. It is just as possible that the actuation of the actuation button 13 takes place directly with the data card itself, which is placed on the front and then with the actuation key 13 in the opposite direction to the arrow direction 14 is pressed inwards.
