Abstract

The invention relates to locking devices and improves the ease of handling and extends the operational capabilities of the overlay cod locks. The lock includes a housing in which a bolt is installed, a locking bar, locking and code discs and handles for moving the bolt. In the case of the lock, between the holes for the projections of the locking plate, there is a groove in which a plate-switch with a lock is pivotally mounted, allowing movement of the bolt regardless of the position of the code disks. At the same time, there are holes in the rear wall of the casing, in one of which a handle is installed that allows controlling the crossbar inside the room, and the other opening is intended for locking the crossbar with the lock of the switch plate. The invention is an improvement of the invention by the author. St. N & 1193266. 7 Il.

BACKGROUND OF THE INVENTION The invention relates to stopping devices and can be used in patch locks.

The purpose of the invention is the race 1; and the operating capabilities of the code lock.

FIG. I presents the scheme of the bay, as seen from the outside; in fig. 2 - the same view from the inside; in fig. 3, the lock is in the “Closed” position, in FIG. 4 - the lock in the “Open” position, in FIG. 5 section A - A in FIG. 3; in fig. 6 is a section BB in FIG. four; in fig. 7 shows section B-B in FIG. 3

The code lock includes a housing 1, a bolt 2, a locking bar 3 with vyst-mention 4 and an axial fastening 5, locking discs 6, having edges 7 on the edges, coded disks 8, an outer handle for retaining the bolt 9, laying 10, holes 11 for the protrusion of the locking bar 3, the leash 12, the switch plate 13, with the interlock latch 14, the longitudinal groove 15, in which the inner handle 16 is placed, readout risks 17, a through hole is made in the wall of the housing 1, and a recess for the inner latch 14. The lock works as follows. Before locking the lock, three code discs 8 turn up from the outside, when the code discs are set with certain numbers to the readout risks 17, then all three flats of the coping to the stonor nlank 3, and the locking ilan 3 together with the protrusion 4 will lower from the hole 11 to the upper level edges of bolt 2. After this, knob 9 rotates the lead 12 1; turn clockwise and move riel 2 in; 1 in. The lock is closed

and to fix it, it is necessary to rotate the code disks 8 to an arbitrary position (to confuse the code). Opening the lock occurs in reverse order. In order to open the lock from inside the room, it is necessary to raise the switch plate 13, which separates the holes 11, on the inner latch 14, the bolt will be released to move, and the lock can be opened by the inner handle 16. To close the lock from the inside of the room, the handle 16 moves the bolt to the "Closed" position, and the switch plate is lowered down and turned to the lock housing, the protrusion 14 through the hole in the lock housing enters the lock bolt, the bolt locks and opens the lock with an external lock. hand impossible.

The use of a pivotally mounted splitter switch plate in the proposed combination lock allows 1Us to improve the handling of the lock and improves its operational capabilities.
