Figure 1 - shows a General view of the key key lock; figure 2 is a section aa of figure 1; figure 3 - shows a General view of the cover of a level lock with a privacy mechanism; figure 4 is a local cutout of the key key lock; figure 5 is a schematic functional diagram of a reader with its nodes; figure 6 - key lock with a transponder.

The level lock contains a housing 1 (see FIG. 1), a cover 2, holes for a key lock 3, 19, grooves 4, 15 (see FIG. 3), fasteners 5, 6, 8, 9, a latch 7, crossbar with a head 10 and a shank 25 (see figure 4), an internal cavity 11 (see figure 2), racks 12, levers 13, guides 14, holes 16, 17, 20, springs 18, through holes 21, secret hole 22, reader 23 with transceiver 33 (see Fig. 5), antenna 24, control unit 34 and electric current source 32 or electric wires, electromagnet 26 with core 27, blocking body 29, additional guide 28, the spring 31, the connecting element 30 and the key lock (see Fig.6) with the transponder 35.

The housing 1 (see Fig. 1) is made of steel sheet material, mainly by stamping, and is a part or assembly unit, mainly of a box shape. The cover 2 is made in the form of a metal plate of arbitrary geometric shape in plan and section. In the housing 1 and in the cover holes are made for the key lock 3, 19, respectively. On the peripheral sections of the cover 2, grooves 4 are made necessary for fixing

lock to the supporting surface. The lock contains fasteners 5, 6, 8, 9 by means of which the cover 2 is fixed to the housing 1. The latch 7 is fixed to the cover 2 and interacts with the end parts of the springs 18. The crossbar 10 contains a head and a shank and is installed with the possibility of authorized movement relative to the housing in guides (in Fig. 1 conditionally pos. not indicated) and communicated with the secrecy mechanism through the shank. The housing 1 has an internal cavity 11. The posts 12 are located in the internal cavity 11, are fixed to the housing 1 and have threaded holes for fasteners 5, 6, 8, 9. The levers 13 (see figure 2) are made of steel sheet material and placed on the guides 14 with limited movement, and the guides 14 are mounted on the cover 2. On the guides 14 there are made through holes 21 (see FIG. 3) and flanges (flanges), the end parts of which interact with the end parts of the uprights 12, and the through holes 21 combined with threaded holes racks 12. On the levers 13 grooves 15 and holes 20 are made, through which the levers 13 interact with the guides 14 and their limited movement (limited movement is provided by the length of the holes 20). The holes 16, 17 are made on the cover 2 and are designed to enter fasteners 5, 6 into them. Each levers 13 are spring-loaded by means of springs 18, with one end part of the springs fixed to the levers 13 and the other interacts with the latch 7. Each levers 13 contains a secret hole 22, the surface of which is formed by depressions and protrusions. The security mechanism of the lock is formed by the levers 13, the springs 18, the guides 14 with through holes 21, the retainer 7, the grooves 15, the holes 20 and the secret holes 22. The security mechanism is mounted on the cover 2 of the level lock. The holes for the key 3, 19 are combined and designed to enter the key into interaction with the security mechanism of the lock. The reader 23 is fixed to the housing 1 or is formed by an integral part of the housing 1, and the reader 23 includes a transceiver 33, an antenna 24, an electric current source 32 or electric wires for supplying electric current, and a control unit 34. The transceiver 33 is electrically in communication with the antenna 24, an electric source current 32 and the control unit 34. The control unit 34 is electrically connected by means of conductive elements, for example, wires with an electromagnet 26 with a core 27. An additional guide 28 is fixed to the housing 1 or formed by part of the housing 1. The blocking body 29 is placed in

additional guide 28 with the possibility of movement (vertical arrows in figure 4) and pivotally communicated through the connecting element 30, with the core 27. The core 27, in the absence of power supply in the winding of the electromagnet 26, is in the extreme extended position by the spring 31. With the extended position the bolt head 10, outside the housing 1, the blocking body 29 (see Fig. 4) interacts with the shank 25, blocking the possibility of moving the bolt towards the inner cavity 11 of the housing 1. The transponder 35 (see Fig. 6) is fixed on the key switch and is installed with the possibility of interaction, by means of an electromagnetic field, with the transceiver 33 via the antenna 24. The additional delay control is based on the identification of the transponder 35 (an electronic single-chip microcircuit that does not have a power source and interacts with the reader 23 through a radio channel with a frequency of 134.2 KHz when using frequency modulation). The identification is based on the verification of the 64-bit identification code of the transponder 35, which is sent as a response to the request of the reader 23. The transponder 35 is powered by the radiated energy of the reader 23 through the antenna 24.

The key key lock works as follows. When the lock key approaches the hole for the lock key 3 or 19, the identification procedure is carried out by applying a signal through the antenna 24 to the transponder 35 and, if the identification is successful, the response signal is transmitted from the control unit to the electromagnet 26, with the core 27 (see Fig. 4 ) is drawn due to the strength of the resulting electromagnetic field, while the compression of the spring 31 and the movement of the blocking body 29 downward and its withdrawal from the interaction with the shank 25, i.e. the deadlock is removed by an additional delay. After that, the key is inserted into the hole for the key 3 or 19 and due to its rotation the authorized bolt is moved towards the housing 1 (the direction of movement in Fig. 1 is shown by arrows). As a result of the rotation of the lock key, the lock key acts simultaneously on both the levers 13 and the shank 25 of the crossbar, with the levers 13 making spring movements relative to the guides 14, each levers 13 making such movements by a certain amount.

The cover of the level lock contains grooves 4 (see FIG. 3), holes 16, 17, an opening for the key lock 19, and the privacy mechanism of the level lock is fixed to the cover, and on the side facing the inner cavity

11 of the lock case 1. The lock secrecy mechanism is formed by levers 13, springs 18, guides 14 with through holes 21, lock 7, grooves 15, openings 20 and secret openings 22. The operation of the level lock secrecy mechanism is described above.

Thus, the claimed technical solution by virtue of the claimed combination of essential features ensures the achievement of the task and obtaining a new technical result. As a result of the proposed design of the key lever lock, an increased counteraction to its unauthorized unlocking is provided, which is ensured as a result of an additional delay using a transponder with an identification code and a reader.
