Description

 The invoice lock with a disk mechanism refers to locking devices and can be used when locking various objects for household and industrial purposes.

 Known door lock containing a spring-loaded beveled crossbar, diverted into the housing with a lever, and a disk lock lock mechanism (SU 1266948 A1, 10.30.86).

 The disadvantages of this lock are the complexity of the design, the complicated and inconvenient to use locking mechanism, as well as the possibility of accidentally locking (slamming) due to the presence of an automatic latch.

 Also known is a cylinder door lock containing a spring-loaded deadbolt-latch with a pin and a mechanism for moving the deadbolt-latch having a cam with a spiral groove (AS USSR 916733, 04/05/82).

 The disadvantages of this design are inconvenience in operation, large dimensions, since there is a direct relationship between the value of the departure bolt and the dimensions of the lock, i.e. the larger the departure of the bolt, the larger the dimensions of the lock, as well as the possibility of accidentally locking (slamming) due to the presence of an automatic latch.

 There is also known a cylinder door lock containing a crossbar installed in the housing, at the end of which a transverse groove is made, a cylinder lock mechanism and a leash connected with it, made of two rings rigidly interconnected by a rod located in the crossbar groove (AS USSR 989017 15.01.83).

 The disadvantage of this design is the inconvenience in operation, because leash rings are rigidly interconnected, and this eliminates the possibility of using the handle, i.e. You can use the lock only on one side - on the side of the cylinder mechanism.

 The technical result achieved in the claimed invention consists in the use of a disc mechanism of secrets in locks without the use of an automatic latch, while maintaining reliability and minimal dimensions of the lock.

 The specified technical result is achieved by the fact that the proposed door lock contains a housing fixed to the door, a box-shaped locking strip, a deadbolt with a bayonet groove, kinematically connected with a spring-loaded crank, a deadbolt lock in the closed position, rotary axially mounted on both sides of the door a handle connected by a screw with a crank, and a disk mechanism with an eccentric kinematically connected with the crank, while the bayonet groove is made in broken, consisting of two straight lines areas that converge at an angle.

The eccentric is made in a semicircular shape, and the crank can be rotated without engagement with the mechanism of secrets by 180 ^o , providing the ability to open and close the lock with a handle.

 To increase reliability from breaking, the box-shaped locking strip is made integral and has a steel plate.

The invention is illustrated by drawings, which depict on:
FIG. 1 - a lock with a locking strap box-shaped in the open position;
FIG. 2 is a section AA in FIG. 1 - disk mechanism of secrets;
FIG. 3 is a view B of FIG. 1 - lock in the closed position;
FIG. 4 is a view B of FIG. 1.

 The lock contains a housing 1, a bolt 2, having a bayonet groove 14, the groove being broken symmetrically to the axis 15 with the apex of the angle directed to the end 13, the crank 3 kinematically connected with the bolt and the eccentric 4, which is fixed in two positions by a spring 5, the latch 6, blocking deadbolt in the closed position, the disc mechanism of the secret 7, the handle 8, the cover 9, the locking box strip 11 with a steel plate 12.

 The castle operates as follows. To close the lock, it is necessary to turn the key, which, in turn, turns the eccentric 4, and the eccentric turns the crank 3, the latter moves the deadbolt 2. The key must be turned until the spring 5 fixes the position of the crank and a characteristic click sounds. This completes the locking cycle. Then, to remove the key from the mechanism of secrets, it is necessary to turn it in the opposite direction until it stops. To lock the bolt in the closed position, move the latch 6.

 When you open the lock, the same processes occur as when closing.

Claims (3)

 1. A door lock, comprising a case fixed to a door, a box-shaped locking strip, a deadbolt with a bayonet groove, kinematically connected to a spring-loaded crank, a deadbolt lock in the closed position, a rotary handle mounted on opposite sides of the door connected to each other by a screw connected to a crank, and a disk mechanism with an eccentric kinematically connected to the crank, characterized in that the bayonet groove is made broken, consisting of two straight sections, converging at an angle. 2. The lock according to claim 1, characterized in that the eccentric is made in a semicircular shape and the crank can be rotated without engagement with the mechanism of secrets by 180 ^o , providing the ability to open and close the lock with a handle.  3. The lock according to claim 1, characterized in that in order to increase reliability from breaking, the box-shaped locking strip is made integral and has a steel plate.
