LOCK WITH SIGNAL DEVICE

The utility model relates to locks with an alarm and can be used in industry, construction and in everyday life.

As a prototype, a lock with an alarm system is selected, comprising a housing with locking elements placed in it, a mechanism for moving the locking elements, and at least two electrical contacts associated with the alarm device A.S. USSR No. 1388530, IPC E 05 B 45/08, published April 15, 88, Bulletin No. 14.

The disadvantages of the known lock are: design complexity, limited functionality (failure of the signal device when trying to break the lock and shift the locking elements) and low reliability due to

the presence of rubbing parts of the contact closure mechanism, which during operation can fail.

The objective of the utility model is to create a simple in design, reliable and multi-functional lock with a signal device.

To achieve this objective, a lock with alarms is proposed, comprising a housing with locking elements placed therein, a mechanism for moving the locking elements, as well as two electrical contacts associated with the alarm device, in which, according to a utility model, the locking elements are made in the form of one or more bolts fixed on the crossbar, the mechanism for moving the locking elements contains a set of levers with labyrinth slots, one of the contacts form the walls of the labyrinth slots in the set of levers and the other is made in the form of a rod fixed through a dielectric gasket on the crossbar, while the rod is located with a gap relative to the labyrinth slots with the possibility of contact with the levers when trying to break the lock, move the crossbars with a foreign object, use a master key or the wrong key.

A comparative analysis of the device with the prototype and with other solutions in the art shows that the set of features set forth is unknown from the existing level of technology, on the basis of which it can be done

utility model novelty.

Compliance of the proposed solution to the criterion of a utility model

industrial applicability can be seen from the following example of a specific implementation of the castle with a signal device.

The utility model is illustrated in the drawing, which schematically shows a General view of the castle with a signal device.

A lock with a signal device comprises a housing 1 with locking elements in it in the form of one or more bolts 2, mounted on a bolt rail 3, and a mechanism for moving locking elements in the form of a set of levers 4 with labyrinth slots 5 and fixing grooves 6, a conclusion about its correspondence criteria

in contact with the pins 7, mounted on the housing 1. On the crossbar 3 through a dielectric gasket (not shown) is fixed to the rod 8, located with a gap relative to the walls of the labyrinth slots 5.

The lock is equipped with a signaling device 9 (buzzer), equipped with a power source (galvanic cell) 10, one end of which is connected to the levers 4 (for example, through the housing), and the other to the rod 8.

The operation of the lock with alarm occurs as follows.

In the operating mode of operation of the castle, its operation is carried out in the usual way, i.e. to open or close the lock, insert and turn the key (not shown). The main beard clings to the crossbar 3 and begins to shift it. The remaining protrusions and depressions on the key beard wring out the levers 4. The labyrinth slots 5 of the levers 4 provide free movement of the rod 8. The barbs of the key, the labyrinth slots 5 of the levers 4 and the trajectory of the rod 8 relative to the slots 5 are precisely matched to each other. In this case, the levers 4 move simultaneously without a shift relative to each other, the rod 8 does not touch the walls of the slots 5 of the levers 4, the electrical circuit of the signaling device 9 does not close.

When you try to mechanical impact on the crossbars 2, using a master key or the wrong key, the suvald 4 is shifted relative to the rod 8. The latter is in contact with the walls

labyrinth slots 5 suvald 4 and closes the electrical circuit of the alarm device. When the contacts (rod 8 and suvald 4) are closed, their friction and mechanical wear do not occur, which increases the durability and reliability of the lock with an alarm.

Using the utility model significantly increases the reliability of the lock with an alarm system and expands its functionality, providing an alarm device when any attempts are made to unauthorized opening or breaking the lock. Moreover, the lock is simple in design and has high mechanical strength, which makes it possible to widely use it. Applicants: ht - P.I. Popov Jj-h E.D. Hapsas
