Description

Known door patch locks with a rotary drum and a bayonet push key, the projections of which interact with spring-loaded cogalts locking drum.

These locks do not exclude the possibility of opening them without a key with foreign objects without disturbing the main mechanism of the lock.

The proposed lock does not have this drawback, and the locking system of the bolt in the lock is less complicated.

A distinctive feature of the proposed lock is that the handle of the locking drum is provided with a lock made in the form of a washer attached to the handle with a protrusion interacting with the recesses of the support bar.

FIG. 1 shows a general view of the castle; in fig. 2 shows a section of the lock along A-A in FIG. one; in fig. 3-section of the lock on BB in FIG. one; in fig. 4 and 5 - key lock in two projections.

In the case 1 of the lock, a rotary drum 2 is placed, at one end of which a handle 3 is mounted, constantly pressed to the case of the lock by a spring 4. The handle 3 is equipped with a lock 5, made in the form of a washer with protrusions, which enters into one of the cuts when turning the lock in the support bar 6. At the other end of the drum 2 in the three holes there are springs 7 and different lengths of zugalts 8. In the housing cover 9 there is a stop drum 10 also with three holes in which the different lengths of chargars are placed //. The holes of the drum 10 coincide with the holes of the drum 2. Lever 12 is rigidly mounted on the drum 10. Under the action of springs, the zugalts 8 enter the holes of the drum 10, which connect the latter with the drum 2. Pin 14 of different lengths are pressed into the bayonet wrench 13, which coincide with the hole and a guide pin 15 of a larger diameter compared to the diameter of the pins 14 to ensure that the pins 14 are correctly inserted into the openings of the drum 10.

When the handle 3 is pulled away and it is turned counterclockwise until it stops, the bolt 16 enters into the housing / and the lock is located at number 93652.

covered position. When the handle 5 is rotated clockwise by 60 °, the bolt 16 is in the self-closing position. By further turning the handle 3 clockwise by 60 °, the lever J2, which is the stop for the bolt, does not allow anything to move the bolt back, while the handle 3 with the clamp 5 is under the action of the spring 4, and the clamp does not allows the reels to turn in any direction. The lock bolt moves while simultaneously turning both drums by means of the lever 12.

The lock opens and closes using a bayonet push-button 13. When the key is pressed to failure, the length of the pins 14 together with the length of zugalts 11 is equal to the length of the drum 10, whereby the charms 8 are squeezed out of the holes of the drum 10 to the interface plane with the drums. This makes it possible to turn the drum 10 with the lever 12 counterclockwise by 60 ° (open) or 60 ° clockwise (counter-closed). When the key is removed from the lock, the zugalt of the drum 2 under the action of the spring 7 enters the apertures of the drum 10 and the lever 12 forms a stop for the bolt 16.

Thus, the lock is closed on the counter-lock and, besides the key from the outside and the handle 3 on the inside, it is impossible to move the bolt 16 with anything.

Subject invention

A door slip lock with a rotary drum and a bayonet push key, the protrusions of which interact with spring-loaded lockers of the locking drum, characterized in that, in order to simplify fixing the crossbar position, the lock handle is provided with a lock made in the form of a protrusion with a ledge rigidly attached, interacting with corresponding cuts in the support plate attached to the lock body.
