Description

In patent No. 3492, rod combination EA; with rotating washers, digital washers locking the rod-key; The washers are located between the fixed ring washers in the lock case and consist of outer rings and inner discs with holes, keyways and spring pins, which serve to change the lock secret. In the proposed modification of the amka, used as a lock, in order to change the secret of the lock, the locks of the locking rod have oblique cuts, which, when the rod is extended, for lifting the spring dogs and disengaging them with pfdvizhnimi letter rings.

In the accompanying drawing, FIG. 1 shows a longitudinal section of a locked lock in which, for clarity, the letter rings are not shown; FIG. 2 is a longitudinal section with inserted letter rings; FIG. 3 letter ring (left view relative to Fig. 2); FIG. 4- front view of the locked lock; FIG. 5- longitudinal section of an open lock without letter rings; FIG. 6-section with up

letter rings; FIG. 7- letter ring - (right view of Fig. 6J; Fig. 8 - side view of the open lock; Fig. 9, longitudinal section of the open lock in a position permitting the rearrangement of the password, but without letter rings; Fig. 10 - longitudinal section with letter rings inserted; Fig. 11 letter ring (right side view relative to Fig. 10) and Fig. 12 - side view of the lock in the password change position.

The lock consists of a case with sockets 7 (fig. 1) in which letter rings 2 with an internal gear surface are placed (figs 2, 3); each ring is equipped with a fixed disc 3 (Fig. 2, 3) and a spring dog 4 (Fig. 2, 7) i which can engage with the teeth of the ring 2 with their teeth. In the case of the lock a core .5 is inserted, equipped with a protrusion 7 and grooves 6 with oblique cuts. The 3 letter rings and the paws 4 have cuts in their body that correspond to the barb profile 6 of the rods. At the outer end of the rod 5, the head 8 is strengthened, which serves to grip the rod as it moves and is equipped with a protrusion that can enter the socket // washers 9 (Fig. 1 and 5); in addition to the nest-77 washer has another nest 10.

Locking and opening of the lock is done by moving the locking rod 5 (fi. 1 and 5) with barbs 6 and tongue 7 to the right or to the left. If all the letter blocks are located in such a way that the cuts in the 3 letter rings and the pawns 4 are mc is just against the barbs 6 of the rod 5, then the rod 5 can be moved to the right (Fig. 5-6) and the lock will be opened. At the same time, the oblique cuts of the pins 6 enter into the cuts of the discs 3 and the attendant 4, but do not produce any pressure on the body of the dogs 4 (the gift of pressing the protrusion 7 into the body of the transfer washer 9 (Fig. 5). press the head 8 of the rod 5 to the left; then the rod will take the leftmost position inside the lock (Fig. 1), after which it remains to mix the letter rings, turning them relative to each other in the slots with 7 fingers, hands in order to hide the password, and the lock will be locked up

To change the lock password, a translational washer 9 is used, having two JO and 77 sockets on its body. In the position of the conversion washer, which responds to locking and unlocking the lock, the socket 77 is opposite the projection of the head 8, which enters the socket 77 when the lock is locked. When the lock is opened, turn the transfer washer so that the socket 10 has to rub out the protrusion 7 of the rod 5j then further pressing the head 8 to the right of the rod from the position shown in FIG. 5, moves to the right, with the protrusion 7 entering the nests 70 of the transfer washer 9 (Fig. 9); then sections of the rod 6 barbs, having pressed the body of the pawls 4 to the right, will raise the body of the pawls 4 upwards (Fig. 10), thus freeing the letter rings 2 from engagement with the pawls 4 (Fig. 11). In this case, the letter rings 2 of the lock can be rotated and by turning them relative to each other, any new password can be installed on the facade of the lock. After that, by pressing the finger on the thumb 8 to the left, the rod 5 is moved to the position. indicated in FIG. 5, and turning the conversion washer P B nd attachment, in which the slot 77 will be

on the top, after which further pressure on the head to the left, the rod 5 is placed in the position that locks the lock (Fig. 1).

i In order for an attacker to not be able to touch the position of the letter rings 2 corresponding to the password, the disks of the 3 rings of letters in his body besides the notch corresponding to the profile of the bit b, another number of smaller notches 72 (Fig. 3), the purpose of which To mislead the intruder, who will try to determine the position of the password by lightly pressing the head 8 to the right and turning the letter rings 2.

In order that when locks are stored after their manufacture and when demonstrating their effect, the password cannot be lost, the locks should be stored at the position of the transfer washer 9, which corresponds to the change of password Dfig. 9-12). To do this, an eyelet 75 is attached to the transfer washer, which, when the position of the transfer washer P, j corresponds to the change of password, rests on the eyelet 14, which is reinforced in the housing. If the wire is threaded through the lugs J3 and 7- and fastened with the clamp 75 (Fig. 12), then the lock will be safe for demonstration, since it will be possible to lose the password, then just take the seal 75, freeing the transfer washer 9 and turning it in the position corresponding to the locking pick.

The subject matter of the invention.

1. The modification of the rod combination lock, described in patent No. 3492, for its use as a lock, characterized in that with a change in the secret of the lock of the lock b and the locking rod 5 (Fig. 1, 5 and 9), there are oblique cuts, servants, at. extending the rod, to lift the spring dogs 4 (Fig. 2, 3, 6, 7, 10 and 11.) and uncouple them from the movable bucky rings 2, which the rod 5 is provided with, moreover, the protrusion 7 (Fig. 1) inserted , when pushing the rod into the socket 10 of the transfer vault 9 operated by the handle 8.

2. Application of the seal 75 for locking the lugs 14 and 13 (Fig. 12) in case of the lock described in paragraph 1 in order to avoid losing the password.
