Description

CASTLE

Technical field

The invention relates to actuators, namely, locks and can be used, in particular, in the construction of household, office and safe locks with manual and remote (radio or wire) control, as well as when creating cocked mechanisms for other purposes, such as protective shutdown devices used in electrical engineering.

State of the art

Known remotely controlled lock company "Sisa" (Italy), the model "Wave", equipped with a latch and a rotary handle. The low-power electric drive of this lock provides the establishment and breaking of an unloaded mechanical connection between the handle and the latch. The operation of the lock is possible without replacing the battery for a long time. However, the need for the participation of the hand when unlocking the lock, namely the rotation of the handle coupled to the latch, does not allow for autonomous or secretive functioning of the product.

The closest analogue to the claimed invention is a lock with wire control "ELECTRIS Rim Los" of the company "Cisa" (Italy), model 11521, which does not require the action of a hand to unlock it. The lock contains a locking mechanism, a first lock designed to block it and made in the form of a pivot arm, a second lock designed to lock the first lock and a drive mechanism of the second lock made in the form of an electromagnet. The locking mechanism comprises a cocking bolt with an entry bevel and a latch spring-loaded outside the lock and interconnected by a powerful spring mechanism necessary for reliable unlocking of the lock. The first latch is installed with the ability to lock the latch. Lock mechanism it is also equipped with a means of clamping the clamp in the direction of its movement, made in the form of a center of rotation of the clamp displaced relative to the latching force. When closing the door, the cocking bolt and the latch under the influence of the frame of the door are sunk into the lock case, the first and second locks go into the locking position, the latch falls into the niche provided for it in the frame and is locked by the first lock in the extended position, the cocking bolt cockes the spring mechanism that compresses the latch inside the castle. To open the lock, the electromagnet is turned on, the second lock releases the first, it releases the latch and the spring mechanism carries it inside the lock, which leads to its unlocking.

This design is equipped with a powerful electromagnet necessary to overcome the friction caused by the considerable force acting on the second latch from the side of the first, which, in turn, is loaded with a spring mechanism through the latch. The presence of a strong electromagnet interferes with the operation of the lock in standalone mode, as it involves the use of a bulky battery, as well as a system for recharging it from the network.

Disclosure of invention

The objective of the present invention is to provide a compact, autonomously functioning, remotely controlled lock with a built-in power source, capable of working for a long time without changing or charging the battery.

The technical result of the invention is to reduce energy consumption in the drive mechanism through the use of mechanical energy accumulated in the lock when it is locked and / or unlocked to compensate for friction between the parts of the lock.

This is achieved by the fact that in the lock containing the locking mechanism, the first latch designed to block it, the tool is tightened by the first latch, installed with the possibility of interaction with the locking mechanism nism, the second latch designed to block the first latch, the drive mechanism of the second latch, the drive mechanism of the second latch is made in the form of a third latch designed to block the second latch, the drive of the third latch and means pushed the second latch, installed with the possibility of interaction with the first latch or locking mechanism.

Signs that distinguish from the closest analogue are:

- a third latch has been added to the design, designed to block the second latch;

- the drive of the third latch is additionally introduced into the design;

- in the design, a means of tightening the second retainer is additionally introduced;

- the tool is tightened second clamp is installed with the possibility of interaction with the first clamp or locking mechanism;

- the drive mechanism of the second latch is made in the form of a third latch, the drive of the third latch and means preloaded the second latch.

MODE FOR CARRYING OUT THE INVENTION

The invention is further illustrated by the description of an example of a specific implementation and the drawings in which: in FIG. 1 shows a kinematic diagram of a lock in a locked state; in FIG. 2 shows a kinematic diagram of a lock in an unlocked state.

In the housing 1 of the device (Fig. 1) there is a locking mechanism containing a bolt 2, movably mounted in the supports 3, the free end of which can be moved outside the housing 1 through a window 4 made in the housing 1. The bolt 2 is equipped with a drive lever 5 and is spring-loaded inside the housing 1 with a working spring 6. The first latch 7 is made in the form of a lever mounted in the support 8 with the possibility of rotation and pressed by the return spring 9 in the direction of blocking the crossbar 2. The first latch 7 has the ability to interact with its the toe 10 with the toe 11 of the crossbar 2. The second latch 12 is also made in the form of a lever mounted in the support 13 with the possibility of rotation and interaction with its toe 14 with the toe 10 of the first latch 7. The second latch 12 is spring-loaded with a return spring 15 in the direction of blocking the first latch 7.

The tool, drawn in by the first latch 7, is formed by the beveled interacting faces of the toe 11 of the bolt 2 and the toe 10 of the first latch 7. When the bolt 2 acts on the first latch 7, the force is directed normal to the interacting faces (in Fig. 1 the direction of force is shown by arrow A). This force acts on the first latch 7 in the direction of unlocking the bolt 2 and creates a preload of the first latch 7.

The drive mechanism of the second latch 12 includes a third latch 16, also made in the form of a lever mounted in the support 17 with the ability to rotate and lock the second latch 12. The third latch 16 is spring-loaded with a return spring 18 in the direction of blocking the second latch 12. The drive of the third latch 16 is made in the form an electromagnet containing a coil 19 and an armature 20 movably mounted inside it. An anchor 20 is connected to the third latch 16 by means of a rod 21. The drive mechanism of the second latch 12 also includes a means of I of the second latch 12, formed, in accordance with the first alternative sign of the invention, the displacement of the center of rotation of the second latch 12 relative to the force of the first latch 7. When the first latch 7 acts on the second latch 12, this force is directed normal to the interacting surfaces (the direction of the force is shown by arrow B ) and creates a moment of rotation of the second latch 12 in the support 13 and, accordingly, causes the second latch 12 to be pressed in the direction of the third latch 16.

In FIG. 1, 2 also shows a means of preloading the second latch 12, which is made in the form of a spring tab 22 (shown by a dashed line in the drawings) mounted on the second latch 12, while the free end of the spring tab 22 has the possibility of interaction with the locking mechanism, namely, the bolt 2.

The device operates as follows. When the lock is locked (Fig. 1), the first latch 7, the second latch 12 and the third latch 16 under the action, respectively, of the return spring 9, the return spring 15 and the return spring 18 are in the initial position, that is, they block each other. In this case, the armature 20 of the electromagnet is pulled out of the coil 19, and the bolt 2 is pulled out through the window 4 outside the housing 1 of the lock and is locked by the first latch 7. The working spring 6 compresses the bolt 2 to the first latch 7, the first latch 7 is pressed against the second latch 12 and the second the latch 12 is pressed against the third latch 16.

To unlock the lock, you must turn on the power of the coil 19 of the electromagnet. When the power is turned on, the armature 20 slides into the coil 19, as shown in FIG. 2, and by means of the thrust 21 turns the third latch 16. The rotation of the third latch 16 unlocks the second latch 12. The second latch 12, under the influence of the first latch 7, rotates towards the third latch 16 and thereby releases the first latch 7. The released first latch 7 under the influence the bolt 2 rotates towards the second latch 12 and unlocks the bolt 2. Under the action of the working spring 6, the bolt 2 moves inside the housing 1. As a result of the above process, the lock goes into the unlocked -being. Then the power of the coil 19 is turned off.

To lock the lock bolt 2 through the window 4 is moved outside the housing 1 by acting on the drive lever 5 and overcoming the action of the working spring 6. In this case, the first latch 7 under the action of the return spring 9 is rotated to the position corresponding to the locking bolt 2. With the rotation of the first latch 7 in turn, the second latch 12 is released and, under the action of the return spring 15, is turned towards blocking the first latch 7. Finally, with the rotation of the second latch 12, the third latch 16 is released, which turns is activated under the action of the return spring 18 to the position blocking the second latch 12. At the same time, when the third latch 16 is rotated, the armature 20 is pulled out of the coil 19. Now the lock goes into the locked state and the movable elements of the lock return to their original position, as shown in FIG. Thus, the means of tightening the second latch 12 allows the energy accumulated by the lock mechanism at one stage to be used at other stages to overcome friction between the parts of the device and compensate for the action of auxiliary springs. Thanks to this, the lock can be controlled by a less powerful and, accordingly, more economical drive mechanism. This makes it possible to create locks with remote control and long autonomous functioning. Manual control of the product is also facilitated: regardless of the strength and massiveness of the lock, it is necessary to release a light effort on the key, button or lever of a manual drive to unlock it.

The considered construction principle of control devices can be applied when creating cocked mechanisms for other purposes, for example, residual current circuit breakers used in electrical engineering.

Since the locking mechanism with the "closest" latches to it can be arbitrarily combined into one functional unit and considered as a locking mechanism, the lock in accordance with the claims may contain a chain of an arbitrary number of latches interacting with each other. The total number of latches in the device is limited by the complexity, reliability and cost of the structure.
