Abstract

FIELD: construction.

SUBSTANCE: lock comprises a body with a cover, a mechanism of bolt displacement and a socket wrench. In the body there are axial holes for freely moving locking pins. Locking pins are made from more than two split parts. One of these parts is arranged in the form of a stepped shaft, the other ones - from cylinders. The mechanism of bolt displacement interacts with locking pins. The socket wrench is arranged with holes located coaxially with axes of locking pins. In the holes of the socket wrench there are stops arranged as fixed in the code position. The lock is also equipped with an autonomous secret block, in which locking pins are installed. The secret block when locking the bolt is rigidly fixed in the body, and in the unlocked position it is extracted, opening access to the bolt or the mechanism of its displacement.

EFFECT: improved security properties of a lock.

Description

The invention relates to locks, in particular mortise locks with push keys, and can be used in apartments and offices.

Currently, modern locks - level, cylindrical, overhead electronic, electronic-mechanical consist of kinematics for moving the crossbars and the secret part, which blocks it and is controlled by a key - mechanical or electronic. Such a design scheme exists in any modern castle, no matter whether it is electronic or mechanical, as well as of a mixed form.

The disadvantage in all locks is the lack of a change in the secret part of the castle when it is unlocked. Take electronic blocking devices, for example. A lot of them release, and as practice shows, within three years there is a way - an algorithm for opening them. The main thing in them is the electronic unit that controls individual nodes - parts of the guarded object. By acting on it or knowing its principle - the algorithm of work, they duplicate the existing connection with a new one, thereby completely blocking the protection.

The closest in technical essence is the castle according to the patent of the Russian Federation No. 2229575 (publ. 27.05.2004). This lock contains a housing with a lid and a rotary disk, in which coaxial holes are made and freely moving locking pins, a deadbolt, a deadbolt movement mechanism including an external handle rigidly mounted on a shaft with a collar, a piston freely mounted on the handle shaft interacting with the locking bolts are installed with pins and a shaft shoulder, a socket wrench made with holes located coaxially with the axes of the locking pins, and located in the gap formed by the ends of the handle and the housing, while the lock is additionally equipped the internal handle, in which the grooves are made and the rollers are installed in them, one roller for interacting with the bolt, the other for interacting with the rotary disk, in which the groove for the roller is also made, in addition, a protective washer is freely mounted on the shaft of the external handle, which positions the locking pins in relation to the socket wrench, moreover, the locking pins are made of more than two detachable parts, one of these parts is made in the form of a stepped shaft, the other is a pin, I freely move it with a guaranteed clearance iysya in the cylinder, and arranged in seven fixed position stops in the socket wrench holes.

However, this lock, as well as all the locks currently existing, has the disadvantage that its secret part is rigidly connected to the entire mechanism of the lock and cannot be replaced immediately without disassembling the lock after unlocking it. As a result of this, a potential cracker knows what it costs and how it works, which means that it can open any lock by making a master key for it, faking a key, etc. The secret part of the lock is replaced, as a rule, when it is broken or if there are any concerns in order to exclude any possibility of a fake key and unauthorized opening of the lock. Imagine that your castle has not one, but several secret parts, which are interchanged at your discretion after each opening of the castle, and in a locked state are firmly fixed in the castle. In addition, they have different secret design features. This allows you to get a lock, which is practically impossible to open criminally, because it is not known what the secret is and what the principle of its operation is. Thus, the criminal resistance of the castle is significantly increased, which is the basis of any such product.

The proposed invention solves the problem of increasing the security properties of the castle by creating a secret part of the castle, which, at the discretion of the owner, can be replaced by unlocking it with any of the similar secret parts.

To achieve this technical result, in the lock containing the housing with a cover, axial holes are made in the housing for freely moving locking pins, and the locking pins are made of at least two detachable parts, one of these parts is made in the form of a stepped shaft, the other of the cylinders, deadbolt, mechanism for moving the deadbolt, socket wrench made with holes located coaxially with the axes of the locking pins, and in the holes of the socket wrench fixed stops in the code position, sleep lock wives secret autonomous unit, which establishes the locking pins, the secret unit when blocking the bolt is rigidly fixed in the housing and in the unlocked state removed, providing access to the bolt mechanism or its displacement. The lock can be equipped with the necessary number of secret blocks (at least two), each with its own key, and can be blocked by any of the available secret blocks.

The distinguishing features of the present invention is the presence of a removable secret unit, in which locking pins are installed with a specific code, the secret unit being rigidly locked in the case when the bolt is locked and removed in the unlocked state, allowing access to the bolt or its movement mechanism. The lock may be equipped with the necessary the number of secret blocks, each with its own code and corresponding hex key, and can be blocked by any of the available secret blocks ov.

The following is an embodiment of the invention that does not exclude other variations within the scope of the claims.

The proposed castle is illustrated by the drawings shown in figures 1-9.

Figure 1 shows a General view of the lock in front with a key;

figure 2 is a section along aa according to figure 1;

figure 3 is a side view;

figure 4 is an isometry;

figure 5 is an isometry (the secret block is removed after unlocking);

figure 6 is a front view without a secret block, the bolt is extended - closed;

Fig.7 is a front view without a secret block, the bolt is retracted - open;

on Fig - isometry without a secret block, the bolt is advanced - closed;

figure 9 - isometry without a secret block of the bolt is retracted - openly.

The lock contains a housing 1 with a lid 2, a bolt 3, a bolt bushing 4 (a bolt moving mechanism in a simplified form - a bolt bushing), a secret block 5, in which are installed locking pins 6 and cylindrical pins 7, a socket wrench 8 and installed in it fixed in stop position 9.

The castle operates as follows. When the secret unit 9 is unlocked and removed from the lock body 1, Fig. 4 and Fig. 5, access is opened to the bolt 3, Fig. 6-9, which can be freely extended from the lock body, Fig. 6, Fig. 8, and retracted along the axis of the sleeve 4 of the bolt 3, Fig.7, Fig.9, under the action of a human hand. In the extended position, the bolt 3 blocks the door (not shown), on which the lock is mounted, since the bolt 3 enters its jamb (not shown). In the retracted position, the door unlocks and can be opened.

In stages, it looks like this:

1. Push the bolt 3 into the body of the housing 1 of the castle, Fig.7, Fig.9.

2. Close the door (not shown).

3. Push the bolt 3 from the body of the housing 1 of the castle, Fig.6, Fig.8. He enters the jamb and locks the door (not shown).

4. Install in the unlocked state one of the available secret blocks 5 in the case 1 of the castle. The secret block 5 is placed in the housing 1 of the castle until it stops and goes into the bolt 3 with its groove made in it. The secret block 5 blocks the movement of the bolt 3, figure 2, along its axis.

5. Insert the key 8 into the secret block 5, which as a result is unlocked, and the part of the block associated with the key 8 can rotate around its axis. We turn the unlocked secret block 5 with the key 8. As a result, the secret block 5 is rigidly fixed in the lock case 1, covering the bolt 3. The lock is closed. We extract the key 8 from the secret block 5.

6. Open the lock in the reverse order. We insert the key 8 into the secret block 5, which as a result of this is unlocked. We turn the unlocked secret block 5 with the key 8. As a result, the secret block 5 no longer covers the bolt 3 and can be removed from the lock case 1 along its axis.

7. Through open access in the case 1 of the castle we push the bolt 3 with your hand into the body of the case 1 of the castle. The lock is open and accordingly a door (not shown) can be opened.

The proposed embodiment of the castle is interesting in that the room can be locked with a secret block both outside and inside. This is possible because the lock case 1 with the cover 2 is symmetrical about the axis of the bolt 3, along which it moves to the open - closed state. On either side of the door, a secret unit 5 can be inserted into the lock case 1 with a cover 2 for closing the door, respectively, from the inside or the outside. It should be noted that this design of the castle is relevant for objects of limited access. It allows you to control all the processes of opening and closing the premises, change secret blocks, which is equivalent to changing locks at any time and as many times as necessary to maintain security at a high level.

Using the design of such locks at several sites, you can create a security system for reliability that has no analogues. The reliability of this system is high only because any secret unit can be replaced at any time. This nullifies possible malfunctions in the operation of the lock mechanism, does not require dismantling of dismantling and other difficulties. The whole basis of the castle - the secret block is always under control, which means there is no reason for its refusal.
