Abstract

FIELD: ironmongery, particularly bar-type locks with pressure keys.

SUBSTANCE: lock comprises body with spring-loaded bar sliding in longitudinal direction. The bar is provided with inclined depressions. The lock also has pressure key made as rod with bit provided with inclined projections formed so that projections may be inserted in depressions of spring-loaded bar. The key bit is fastened to key rod and spaced apart therefrom. The body has through orifice to receive key rod with key bit from outer lock side so that the key rod with key bit extend with respect to the body from inner side thereof. Blind hole is made from inner body side to receive key bit. The blind hole is communicated with inclined bar orifices. The second spring-loaded bar sliding in longitudinal direction is installed in the body. The second spring-loaded bar also has inclined depressions. The key has the second bit with inclined projections to be inserted in depressions of the second bar. The second key bit is connected to key rod and spaced apart therefrom. Blind hole to receive the second key bit is created from inner body side. Both blind holes are diametrical with respect to through orifice axis having shape mating that of cross-section defined in key rod with bits.

EFFECT: increased secrecy and reliability of the lock.

Description

The invention relates to the field of hardware and relates, in particular, to locks and locks with a key.

A known lock containing a housing mounted in it with the possibility of longitudinal movement of a spring-loaded rail with inclined hollows, a push key made in the form of a rod having a beard with inclined protrusions for placement in the inclined hollows of the rail, mounted on the rod with a groove between them, a through hole made in the housing for the passage of the rod together with the beard from the outside of the lock until they exit the housing from the inside, and a blind hole made on the inside of the housing under the beard of the key and which communicates with the inclined hollows of the rail, RF application No. 2003123640, cl. ЕВВ 35/04, February 27, 2005.

In this lock, the key has one beard that interacts with the rail. In this case, the through hole is made so that there is a large space for penetrating to the inner side of the lock and acting on the locking mechanism. Since the qualifications of cybercriminals are constantly increasing, then having studied the well-known castle when it entered the market, opening it would not be difficult.

Therefore, the objective of the invention was to create a castle with a higher degree of secrecy and reliability of the castle. At the same time, the lock is made so that its external keyhole in shape corresponds to the wells of level locks with double-sided keys, thus disorienting a possible attacker, which increases the degree of security of the castle.

The task of increasing reliability and secrecy is achieved by the fact that the proposed lock contains a housing mounted in it with the possibility of longitudinal movement of a spring-loaded rail with inclined hollows, a push key made in the form of a rod having a beard with inclined protrusions for placement in inclined hollows of the rail, mounted on the rod with the formation of a groove between them, a through hole made in the housing for the passage of the rod together with the beard from the outside of the lock to their exit from the housing with light on the internal side, and a blind hole provided with an inner side of the housing under the key bit and which communicates with the inclined troughs slats. A second spring-loaded rail with inclined hollows is installed in the housing with the possibility of longitudinal movement, and the key has a second beard with inclined protrusions for placement in the inclined hollows of the second rail, while the second beard is mounted on the rod with the formation of a groove between them, on the inside of the second a blind hole for the second beard and both blind holes are located diametrically relative to the axis of the through hole, and the shape of the latter coincides with the cross section of the rod with the barbs .

The invention is illustrated by drawings, which depict on:

figure 1 - castle, General view;

figure 2 is a section aa in figure 1;

figure 3 - push key.

The lock comprises a housing 1, spring-loaded rails 2 with inclined troughs 3, mounted in the housing with the possibility of longitudinal movement and interaction with the locking strip 4, under the action of a push key with a rod 5 and with inclined projections 6 located on two diametrically located barbs. The rails 2 are spring-loaded with springs 7, and through the holes in the lock case through holes 8 are made, coaxial with the holes 9 in the rails for fixing the rails in the open position with a cotter pin (not shown). There is a locking screw 10 to limit the working stroke of the rail.

A through hole 11 is made in the lock case for passing the key rod together with the barbs from the outside of the lock until they exit the case from the inside. On the inner side of the housing there are blind holes 12 for the key beards, which communicate with the inclined hollows of the rails. Between each blind hole 12 and the through hole 11 there are partitions 13 that interact with the grooves 14 in the pressure key. The shape of the well 15 coincides with the cross section of the rod 5 with the barbs.

The castle operates as follows.

Insert the pressure key into the through hole 11 of the lock body 1 until the working part of the key with the barbs leaves the case, turn it until the barbs coincide with the blind holes and move it towards you. In this case, the inclined protrusions 6 of the key enter the inclined depressions 3 of the rails 2 and move the rails inside the lock case. The castle is open. By the reverse movement of the key from themselves, the rails are removed from the housing, after which the key is turned and removed from the lock. The lock is closed.

Technical and economic advantages of the proposed castle are due to its simplicity, reliability, manufacturability, because the design of the castle uses a minimum number of parts, and its manufacture uses sheet metal, profile.
