Description

Locks are known that contain a bolt, a spring-loaded latch, the end of which is rigidly connected to a spring-loaded lever that interacts with the fold handles, and a set of zugalt.

Prefixed lock is more convenient and has more secrecy. This is achieved by the fact that it is provided with a handle that covers the rod of the falovy handles and is freely mounted on one of them, having an end part in the form of a cam half coupling, and a permanent key, made in the other half half coupling, radially located outside the jaws. One of these cams interacts with the bolt, and the other with zugalts.

FIG. 1 shows the proposed lock in a perspective view; in fig. 2 - the same, vertical section and section along A-A.

Lock slammed into the door. It consists of a body /, a bolt 2, a spring-loaded latch 3, the end of which is connected to the spring (with a lever 4, interacting with the felted handles 5 and 6. These handles are on the opposite sides of the lock body, and the handle 5 has a square rod 7, which passes into the hole of the lever 4, through the body / ive of the square opening of the fale handle 6. The handle 8 is freely attached to the latter, with the end part in the form

cam coupling half 9. This coupling half with protrusions enters the recesses of the permanent key 10, made in the form of a tubular coupling half, having radially located outside cams P and Pa. A permanent key is fitted with a set of zugalt 12 with a different profile of the recesses 13, on which the asymmetrical barb 14 of the key 15 acts, which is inserted into the keyhole 16 and turned in it when the lock is unlocked and unlocked outside the room.

Falev handle 5 with its square rod 7 enters the permanent key 10, and upon exit to the other side of the body / -in a square opening of the fale handle 6.

The crossbar has teeth 17 at the top, which are affected by the cam // when turning the fixed key 10 to one or the other side, and below the crossbar - a guide pin

8-interacting with grooves 19 zugalt 12.

Open and close the lock from inside the room with a permanent JO key. The lock works as follows.

When closing the lock from the inside of the room, the handle 8 connected with the permanent key 10 by the projections of the half coupling 9 turns the key 10 clockwise. This key, with its cam On, lifts the zugalts 12, open it with the grooves / P zugalt, and the cam 11 moves the bolt 2. To the left and locks the lock.

They open the lock from the inside in the same sequence as they close, but at the same time the handle 8 of the permanent key 10 is turned in the opposite direction.

Close the lock from the outside of the room with a single-bore key 15 inserted into the knock-through hole 16, while the key 15, turning relative to its axis, comes into contact with all zugalts, simultaneously lifting them by the same amount, releasing the guide pin 18 of the grooves 19 zugalt 12, and the lateral key 14 of the key moves the bolt 2 locks to the left and locks the lock.

The lock is opened outside the room in the same sequence as it is closed, but

while the key 15 is rotated in the opposite direction relative to its axis.

Pre invention

A lock containing a deadbolt, a spring-loaded latch, the end of which is rigidly connected to a spring-loaded lever that interacts with the falovy handles and a set of zugalt, characterized in that, in order to increase

ease of use, it is equipped with a handle covering the stem of the fold handles and freely mounted on one of them, having an end part in the form of a cam

the coupling half, and the fixed key, EXECUTED as another half coupling, having radially located cams, one of which interacts with the transom, and the other with zugalts.
