Abstract

The claimed invention relates to locks in which a bolt acts as the locking member, which bolt is in kinematic connection with a security mechanism. A lock contains a housing and, positioned therein, a bolt, which performs primary displacement for locking and unlocking the lock, and a security mechanism, which provides for the primary displacement of the bolt. The lock also contains at least one additional drive, which provides for at least one additional displacement of the bolt so as to open and close the kinematic connection between the bolt and the security mechanism. In another variant of the invention, the bolt consists of a first bolt portion which is in kinematic connection with at least one second bolt portion, wherein the opening and closing of the lock is carried out by the first bolt portion. The security mechanism provides for the primary displacement of the bolt by transferring motion from the first bolt portion via the displacement of the at least one second bolt portion, and the at least one additional drive provides for the opening and closing of the kinematic connection between the security mechanism and the at least one second bolt portion. The technical result of the invention consists in increasing the security level of a lock.

Description

CASTLE

The invention relates to locks, in particular to locks in which the locking element is a deadbolt, which is in kinematic connection with the secrecy mechanism.

There are a large number of locks used to lock doors, safes, etc., in which the locking element is a deadbolt, which is pulled out of the lock body. A deadbolt is actuated by a secrecy mechanism that is kinematically connected with a deadbolt. The bolt is pushed out of the lock housing and enters the mating hole located, for example, on the jamb of the doorway, thereby locking the door. A reverse turn of the key pushes the deadbolt into the housing, allowing the door to open freely. Thus, the deadbolt and the secrecy mechanism are in kinematic connection, which ensures the back and forth movement of the deadbolt to bring the lock into open or closed state, respectively.

The bolt can be extended both in the direction perpendicular to the surface of the castle body from which it exits, and at an angle to it. European patent application EP1473424 (published 03.11.2004; IPC E05B15 / 10, E05B63 / 14, E05C9 / 18) describes a lock with three deadbolts, one of which, deadbolt 42a, performs a reciprocating movement perpendicular to the front wall 22, and two others - deadbolts 44a, 46a - reciprocating movements at angles to the front wall 22. All the deadbolts are in constant kinematic connection with each other, as well as with the rod 68, driven by a secrecy mechanism.

The patent SU1834968 (published August 15, 1993; IPC E05B15 / 10, E05B63 / 12) discloses a lock, the deadbolt of which consists of two rods 2, which perform reciprocating movements and are kinematically connected with the tail part 10, which, in turn, is constantly kinematically connected to the control of the rotating cam 13.

The lock according to SU 1834968 is selected as the closest analogue of the present invention.

The disadvantages of the above and other known solutions is that when gaining unauthorized access to the management of the privacy mechanism, for example, by selecting a key, an attacker can open the lock and, therefore, gain free access to the protected facility. Known methods for increasing the secrecy of locks lead to a significant complication of their design, an increase in mass and dimensions.

The objective of the present invention is to develop a lock of simple design, which provides a closed state of the lock even when gaining unauthorized access to control the privacy mechanism.

The technical result of the invention is to increase the level of secrecy of the castle and its resistance to hacking.

The problem is solved in that in the first embodiment of the invention, the lock comprises a housing and a deadbolt arranged therein, configured to perform a main movement, providing for locking and unlocking of the lock, and a secrecy mechanism providing said basic movement of the deadbolt. In addition, the lock contains at least one additional drive, which provides at least one additional movement of the deadbolt for opening and closing the kinematic connection between the deadbolt and the secrecy mechanism.

The problem is also solved in another version of the lock containing the housing and the deadbolt located therein, consisting of kinematically connected first part of the deadbolt and at least one second part of the deadbolt and made with the possibility of the implementation of the main movement, providing locking and unlocking of the lock, carried out by means of the first parts of the deadbolt, and a secrecy mechanism providing the main movement of the deadbolt by transmitting the movement of the first part of the deadbolt through the movement of at least one second part and deadbolt. In addition, the lock contains at least one additional drive, providing the opening and closing of the kinematic connection between the secrecy mechanism and at least one second part of the deadbolt.

The lock according to any of the above options can be made in such a way that the movement of the bolt of the first variant of the lock or at least one second part of the bolt of the second variant of the lock is a translational movement, or a rotational movement, or any combination thereof. This allows you to create locks with a high level of protection against burglary or unauthorized opening depending on the required level of protection, permissible overall dimensions of the castle, etc.

In addition, at least one additional drive may be a mechanical, or magnetic, or electromechanical, or electromagnetic device, or any combination thereof. It also allows you to create locks with a different level of protection against burglary or unauthorized opening, various weight and size indicators, etc.

Further, the work of the claimed variants of the castle is explained in more detail with reference to the attached figures.

Figure 1 shows the lock according to the first embodiment of the invention, the deadbolt of which performs a reciprocating additional movement.

Figure 2 shows the lock according to the first embodiment of the invention, the deadbolt of which carries out rotational additional movement.

FIG. 3 shows a lock according to a second embodiment of the invention, the second part of the bolt of which carries out translational motion.

Figure 4 shows a lock according to a second embodiment of the invention, the second part of the deadbolt of which carries out rotational movement.

5 shows a lock according to a second embodiment of the invention, the second part of the deadbolt of which carries out rotational movement.

The lock according to the first embodiment of the invention includes a housing (1), in which a deadbolt (2) and a privacy mechanism (3) are placed. Thanks to the cam (4) of the secrecy mechanism (3) and the reciprocal groove (5) on the bolt (2), the secrecy mechanism (3) and the bolt (2) are included in the kinematic connection, which ensures the bolt (2) is pulled out of the housing (1) through an opening in the side surface (6) of the housing. In the open state of the lock (figa) the bolt (2) is essentially entirely in the housing (1), and in the closed state of the lock the bolt (2) is pulled out of the housing (1) (Fig. Lb). The specified movement of the bolt (2), providing the opening and closing of the lock, hereinafter referred to as the main movement.

One skilled in the art will recognize that the deadbolt (2) can be either the deadbolt itself, or the bolt, or the spring-loaded deadbolt, also known as a latch or door latch, which are within the scope of the present invention equivalent, because they perform the same function - provide closing and opening of the object on which the inventive lock is installed.

It will also be clear to a person skilled in the art that the mechanism of secrecy (3) can be a cylindrical mechanism (as shown in the figures), and a suval mechanism, and generally any mechanical, electromechanical, electrical secrecy mechanism, which are equivalent in the framework of the present invention, since perform the same function - provide locking and unlocking the lock when they are in kinematic connection with the bolt (2).

In addition, the lock contains at least one additional drive

(7), which provides one or more additional movements of the bolt (2), so that the kinematic connection between the secrecy mechanism (3) and the bolt (2) is broken. For example, as shown in FIG. 1c, in the closed state of the lock, the deadbolt (2) by means of an additional drive (7) can be extended further from the housing (1) through an opening in the side surface (6), compared to its extension shown in FIG. . lb. In this case, the cam (4) in any position will no longer be able to contact the groove (5), which means that the secrecy mechanism (3) will not allow you to open the lock even if the secrecy mechanism (3) is cracked or a key is picked up to it.

As can be seen from FIG. la, lb, 1c, the additional movement of the bolt (2) is translational and is provided in this particular case by the translational movement of the additional drive (7) along the guides (8).

For a specialist it is clear that other examples of the implementation of additional movement of the bolt (2) are possible, for example, rotational movement around an axis perpendicular to the plane of the figure, as shown in FIGS. 2a, 2b, 2c. In the closed state of the lock shown in FIG. 2b, one or more additional drives (7) rotate the bolt (2) around an axis perpendicular to the plane of the lock (and the figure) - see fig. 2c, thereby removing the part of the bolt (2) in which the groove (5) is located, from the cam (4), so that the cam (4) in any of its position can no longer be kinematically connected with the groove (5). Obviously, such additional movement of the bolt (2) requires a certain implementation of the corresponding holes on the side surface (6), allowing deadbolt (2) to carry out not only reciprocating main movement, but also rotational additional movement.

It will also be clear to a specialist that an additional movement of the deadbolt (2) may be its rotation along the longitudinal axis of the deadbolt (2), rotation around the axis vertical and lying in the plane of the figure, any combination of rotational and translational motion, etc.

An additional drive (7) can be any mechanical, magnetic, electromechanical, electromagnetic device, or any combination thereof. In addition to those shown in FIGS. 1-5, it can be a simple mechanical lever controlled by pressing on it and pushing the bolt (2) when the bolt (2) is in the position corresponding to the closed state of the lock; or another secrecy mechanism; or a magnet, including an electromagnet; or a magnet mounted on a mechanical lever or another secrecy mechanism; or an electromagnetic motor, including remotely controlled; etc.

An additional drive (7) can be completely placed inside the lock case, for example, if it is a magnetic device or another secrecy mechanism. Alternatively, the additional drive (7) can be controlled remotely, for example, using a magnetic card or magnetic key.

Also, the additional drive (7) can only partially be placed inside the lock case, for example, if it is made in the form of a mechanical lever, button, etc.

Specialist in the field of technology can apply in the lock other types of additional drive (7), not limited to the above.

It is significant that an additional drive (7) or several additional drives (7) (for example, to increase the level of secrecy) can break the kinematic connection between the secrecy mechanism (3) and the bolt (2) (Figs. 1c, 2c) when the bolt (2) translates into a position corresponding to the closed state of the lock (Fig. Lb, 2b).

Figure 3-5 shows the possible execution of the castle according to the second embodiment of the invention. In this case, the bolt consists of two parts - the first part (2a) of the bolt and the second part (2b) of the bolt, kinematically connected to each other. The first part (2a) provides for locking and unlocking the lock. The second part (2b) provides a kinematic connection with the secrecy mechanism (3).

In the open state of the lock (Fig. Za, 4a, 5a), the first part (2a) of the bolt is pushed into the housing (1). In this state, the movement of the second bolt part (2b) is controlled by the position of the cam (4). The movement of the cam (4) causes the movement of the second part (2b), which, in turn, causes the movement of the first part (2a), thus translating the lock into the closed state (Fig. 3b, 4b, 5b).

Further, the activation of the additional drive (7) drives the second part (2b) of the deadbolt, opening the kinematic connection between the second part (2b) and the cam (4) (Figs. 3c, 4c, 5c), so that any further movement of the cam (4 ) will not have any effect on the second part (2b).

The first part (2a) and the second part (2b) can perform relative rotational motion, for example, around an axis passing through the connecting element of the first part (2a) with the second part (2b), as shown in FIG.

Alternatively, said parts of the deadbolt (2a, 2b) can be moved relative to each other, performing mutual reciprocating motion, as shown in FIG. 4.

The opening of the kinematic connection between the second part (2b) and the cam (4) according to the variant shown in Fig. H is carried out by means of an additional drive (7) moving up and down and thus raising and lowering the second part (2b) relative to the cam (4 )

The additional drive in figure 4 is not shown, but it can be any well-known specialist or from the materials of this application, for example, similar to that shown in figure 1. In the latter case, the movement of the additional (7) will cause the second part (2b) to move in the opposite direction relative to the direction of movement of the first part (2a) when the lock is closed, so that the cam (4) in any position will not come into contact with the second part (2b) .

A more complex version, shown in Fig. 5, can be implemented, where a constant kinematic connection between the first part (2a) and the second part (2b) is carried out by means of a slider (9) moving along the groove (10), performed in the first part (2a) without breaking the kinematic connection between the first part (2a) and the second part (2b) with their simultaneous longitudinal movement. After bringing the lock into a closed state, an additional drive (7) (not shown) allows you to rotate the second part (2b) along the longitudinal axis of the second part (2b), so that the recess (11) is above the cam (4). Thus, the kinematic connection between the cam (4) and the second part (2b) is broken, and any further movement of the cam (4) will not have any effect on the second part (2b).

Any other mutual movements of the first part (2a) and the second part (2b) of the bolt can be realized. In addition, the second part (2b) can, in turn, consist of several parts in order to ensure increased secrecy of the castle or the implementation of the castle with several additional drives (7).

Similarly to the first embodiment of the invention, in the second embodiment of the invention, any types of additional drive (7) or several additional drives (7) known in the art can be used. It is significant that the additional drive (7) or several additional drives (7) can break the kinematic connection between the secrecy mechanism (3) and the second part (2b) of the bolt, when the first part (2a) of the bolt is in a position corresponding to the closed state of the lock.

The proposed versions of the lock according to the present invention allow, without complicating the secrecy mechanism, to significantly increase the reliability of the lock against breaking or unauthorized use.
