Abstract

Usage: increase the reliability of the lock and the security of the castle. SUMMARY OF THE INVENTION: two crossbars with gear racks alternately engage with a gear sector. The sector is mounted on a cup having longitudinal movement along the key guide. In the closed state of the lock, the gear sector is a latch. Radial holes for the pins are made in the key guide. The pins interact with slots and grooves made on the key and plug. A permanent magnet is fixed on the key, which interacts when opening and closing the lock with the end of the glass made of magnetic material. 2 ill.

Description

FIELD OF THE INVENTION The invention relates to locking devices, namely to padlocks.

A door lock is known comprising a key guide housing, a crossbar located in the housing, a crossbar moving mechanism, an additional crossbar made in the form of a gear rack, the drive mechanism comprising a gear sector interacting with the crossbar teeth, a key and fixing means.

The well-known castle has low secrecy and insufficient security lock.

The purpose of the invention is to increase the secrecy and reliability of locking the lock.

This goal is achieved by the fact that it is equipped with a plug with slots, the guide for the key is hollow to accommodate the plugs and has pins fixed to its inner surface for placement in the plugs of the plugs, the drive disk is mounted by means of a hub made in the form of a cup, and placed on the guide for the key with the possibility of movement along it to form means of fixation, and the key is equipped with a permanent magnet fixed to the end of its shaft and slots on the side surface under the pins for the guide the cap and the bottom of the hub are made of magnetic material to interact with the key magnet during unlocking, the bolt having grooves for receiving the fixing means.

Fig. 1 shows a padlock (closed), general view; figure 2 is a section aa in figure 1.

The lock comprises a housing 1, in the longitudinal holes of which there are bolts 2, on which are mounted the rails 3, the guide 4, into which the key 5. is inserted, is made cylindrical. Radial holes are made in the guide in several transverse rows (the number in the row can be 1,2,3,4), into which the pins are inserted 6. On the guide 4, a hub 7 is installed, made in the form of a glass, at the end of which 8, projections 9 are made. In the crossbars, grooves 10 are made behind the rails, and on the hub 7 there is a gear sector 11, the edges of which in a fixed state (closed lock state) are located in the grooves 10. A permanent magnet 12 is fixed to the end of the key, and sideways

On the end surfaces of the ends of the key 5 and the plug 13, the slots 14 and the grooves 15 are made, a shoulder 16 is made at the end of the plug, and a sample 17 is made in the guide, and the depth of the sample 17 is greater than or equal to the width of the shoulder 16. The plug 13 and the end face of the hub 8 are made of magnetic material.

The castle operates as follows.

In the initial position (the lock is closed), the guide 4 is closed by the plug 13. To open the key 5, the magnet 12 is attached to the end face of the plug 13 and, by turning and feeding it, the plug is removed from the guide at the moment when the slots 14 coincide with the pins 6 of the corresponding row and the pins will come out of the groove 15. Then the key 5 is inserted into the guide, and only if its slots 14 are passed through the pins 6 of several rows, it enters with the same slots into the protrusions 9 of the end face 8 of the glass 7 and thanks to this and the magnetic forces between the constant Agnita 12 and the end face 8 is fixed in the lock.

After this, by longitudinally moving the key 5 and the hub 7 connected therefrom, the sector 11 is removed from the grooves 10 of the crossbars, i.e. lock unlocking.

Further, sector 11 is introduced when it is turned clockwise and is moved into engagement with the rail of the upper crossbar, and when the key is turned counterclockwise, the crossbar is retracted into the lock case. Then, the gear sector is disengaged from the upper crossbar by moving the key 5 from itself and after turning counterclockwise by a certain angle and the movement towards itself is engaged with the lower crossbar. When turning the key

clockwise, the lower crossbar retracts inward. The order of extension of the crossbars - upper and lower - is arbitrary. To facilitate the rotation of the key at predetermined angles,

providing engagement with the bolt, they can be applied to the front side of the lock in the form of, for example, points showing the angle of rotation of the key handle relative to the vertical axis of the lock; locking the lock occurs in a similar way.
