Description

The invention relates to locking technology and is intended for use in residential and public buildings, vehicles.

A number of door locks are known without a key hole (patents RU No. 2101449 C1, RU No. 2117128 C1) with a secret mechanism with free locking elements, in which the latter are made in the form of magnetically sensitive balls and move freely in the corresponding cylindrical cavities.

The closest in technical essence to the claimed technical solution (prototype) is a door lock (patent RU No.2002931 C1, E 05 B 47/00). The lock contains a housing with a borehole and a keyway, located in the housing coaxially with a blind cylindrical guide nests made perpendicular to the keyway, and a spring-loaded panel mounted with axial movement and carrying pistons with holes on the free ends, magnetically sensitive delays made in in the form of balls made of magnetically sensitive material and arranged in one cage in each socket with the possibility of placement in the piston holes, a means for controlling the locking device tion, comprising a shaft with a protrusion associated with the shank by means of a locking device and spring-loaded by a cam plate, and the key to the control magnetic blocks and installed in them in order seven magnets to magnetically interact with delays. The holder sockets are filled with an inviscid anticorrosive and non-magnetic fluid that does not freeze at low temperatures. The keyway is located under the nests and is made in the form of a slit with a slope towards the well, and the pistons are equipped with compensation slots for the transition of fluid. At least one of the sockets is provided with one or more additional delays. The magnetic blocks of the key contain additional magnets for interaction with the corresponding additional magnetically sensitive delays. Pistons in the seats are made with an appropriate number of holes for magnetically sensitive delays. The spring-loaded panel has profiled positional openings, and the ends of the pistons connected to the panel are made with corresponding positional faces that can be aligned with the panel openings, while the magnetic key blocks are installed with the possibility of discrete rotation. The lock is equipped with spring-loaded pins located in the holes of the cage for interaction with the movable panel and the key, and the key is made with holes opposite the pins.

The disadvantages of the mechanism of the secret of the prototype are the design complexity, low reliability and resistance to hacking.

The technical result achieved in the invention is to eliminate the disadvantages of the prototype.

This is ensured by the fact that the lock secret mechanism proposed by the authors with free locking elements comprises a turnkey housing, a spring-loaded locking device with a matrix located in the housing, in the blind cavities of which are installed magnetically soft material in the form of balls or bodies of revolution, the forms of which are parallel or inclined at a certain angle, the shaft with a handle and a shank for controlling the locking mechanism and the key with permanent magnets, characterized in that the keyway is through and normal to the shaft, the shaft carries an eccentric kinematically connected with the lock, the matrix is made with blind longitudinal cavities and protrusions for the code grooves in the lock, the permanent magnets in the key are aligned with the code grooves in the lock and the protrusions in the matrix, the housing has a spring-loaded key lock, and the key - hole for the retainer.

Figure 1 shows a General view of the mechanism of the secret of the lock with free locking elements with a flat magnetic key inserted into the groove of the housing; figure 2 is a General view of the mechanism of the secret of the lock with free locking elements from the shaft with the eccentric in the closed position; figure 3 is a flat magnetic key; figure 4 is a General view of the mechanism of the secret of the lock with free locking elements from the shaft with the eccentric in the open position.

The design of the lock secret mechanism with free locking elements is illustrated in FIGS. 1-4 and includes a housing 1 with a groove 2 for a flat magnetic key 3, housed in a housing 1 spring-loaded 4 lock 5 with a matrix 6. In the blind longitudinal cavities 7 of the matrix 6 are installed blocking elements 8 of soft magnetic material (for example, in the form of balls). The shaft 9 with the handle 10 and the shank 11 are used to control the locking mechanism (not shown). The groove 2 is through and normal to the axis of the shaft 9. The shaft 9 carries an eccentric 12 kinematically connected to the lock 5. The matrix 6 contains blind longitudinal cavities 7 with projections 13 under the code grooves 14 of the lock 5. Permanent magnets 15 in a flat magnetic key 3 are set in accordance with its code and simultaneously coaxial with the code grooves 14 of the lock 5, the housing 1 of the secret mechanism has a spring 17 of the lock 17 of the key 3, and the last has an opening 18 under it (17).

The lock secret mechanism with free blocking elements can be in one of two positions: locked or free. In the locked position, the locking elements 8 are under the influence of gravity in the lower part of the longitudinal blind cavities 7 of the matrix 6. In this state, the blocker 5 eliminates the rotation of the handle 10 of the shaft 9 with the eccentric 12, and thereby open the lock.

In the free position, the secret mechanism is translated using a flat magnetic key 3. When the key 3 is inserted into the groove 2 of the housing 1, its permanent magnets 15, set in accordance with the code, sequentially interact with the blocking elements 8. As a result of this interaction, the blocking elements 8 move to the code position: opposite the code grooves 14 of the lock 5. In this case, the final position of the key 3 in the groove 2 is fixed with the spring 17 of the lock 17 and the hole 18 on it (3). Rotating the handle 10, the eccentric 12 of the shaft 9 acts on the lock 5, spring-loaded with a spring 4, as a result of which the locking elements 8 are (fall) in the code grooves 14 and at the same time the locking mechanism is opened through the shank 11.

In the free position, the secret mechanism is translated by rotating the knob 10 and then removing the flat magnetic key 3 from the groove 2 of the housing 1. In this case, due to the eccentric 12, under the action of the spring 4, the blocker 5 moves in the opposite direction. Under the action of gravity, the locking elements 8 will take the initial position in the lower part of the longitudinal blind cavities 7 of the matrix 6.
