Description

The invention relates to locks of increased secrecy and can find application both in everyday life - for apartment door locks, and in banks, institutions, etc. - for safes.

From the patent of the Russian Federation No. 2215106, class. E05B 47/00, publ. 10.27.2003 a lock is known that contains a housing in which the cylindrical part is mounted rotatably, there is a key insertion hole, locking pins installed with the possibility of sliding inside the radial holes in the cylindrical part and open towards the axial well, the pins being made with the possibility of interaction at one end with a key and for at least one pin, the means for biasing it are magnetic biasing means and comprise a permanent magnet.

According to the creators, the invention provides a high degree of protection compared to well-known locks of this type.

However, the presence of magnets that ensure the accuracy of the axial movement of the pins during angular rotations of the cylindrical part of the lock casts doubt on the service life of such a lock precisely because of the natural properties of the magnet, since the action of the magnet weakens over time. In addition, there is always the possibility of manufacturing the key itself using modern means, such as scanning, etc.

The locking mechanism of the lock is also known from the description of the USSR copyright certificate No. 1211403, MPK4B 27/08, publ. 02/15/86, bull. No. 6 (prototype).

The lock contains a housing, a movable block (in the description - a drum) installed in the housing and having a hole for inserting a key into it, spring-loaded pins (in the description - pushers), symmetrically and movably installed inside holes made in the lock housing with access to the outside the surface of the housing, and the movable handle (in the description, the leash) and the fixing means interacting with the socket wrench.

The lock is designed to simplify the design and increase privacy. However, this design and the presence in the end key of two protruding pins makes it possible to play the key without any difficulties, and therefore, the unreliability of the design.

An object of the present invention is to provide a high security lock having a higher degree of protection compared to known locks.

This technical problem is solved due to the fact that the lock containing the housing, a movable block installed in the housing, spring-loaded pins that interact with the socket wrench, symmetrically and movably placed on both sides of the axis of the movable block inside the holes with access to the outer surface of the lock housing , a handle and fixing means, characterized in that the spring-loaded pins are installed in rows of at least three in each, have different lengths and axial displacement, and the pins on the overhead wrench have a height of up to sufficient for interacting with the corresponding end face of each spring pin, while the middle part of each spring pin is made concave with the possibility of interaction with the convex part of the movable block of the lock, the handle of the lock being connected to the fixing means with the possibility of release from fixing at the moment of interaction of the socket wrench with spring pins and connected to a movable block, providing opening of the well for the introduction of a flat key into the tail of the movable block, i bolt-governing, closing the lock.

In addition, one or more spring-loaded pins on the inside of the door are connected to a device for transmitting an audio signal or a signal to the security control panel in case of an unauthorized attempt to open the lock.

The design of the lock and the key to it are difficult to reproduce, they have several protection options at the same time, which ensures the reliability of its operation and increased secrecy.

The lock 1 (figure 1, 2) contains a housing 2 with an internal cavity in which a movable block 3 with annular grooves is installed, which at one end has an opening 4 for a handle 5 connected to the movable block 3, and at its other end the tail part 6, which is a deadbolt, has a well 7, which is closed when the lock 1 is closed and there is no access to the lock 1.

Holes 8 are symmetrically made in the housing 2 on both sides of the axis of the movable block 3, in which pins 9 with springs 10 are movably mounted coaxially with the holes 8. The spring pins 9 have different lengths and axial displacement sizes. The spring pins 9 are installed in rows, for example two, as shown in figure 2. At least three spring-loaded pins 9 are installed in each row. The holes 8 in which the spring-loaded pins 8 are installed have access to the outer surface of the lock housing 2. Each spring-loaded pin 9 is in the middle part, but at a different distance from the open outer end of the spring-loaded pin 9 has a concave surface, which has the ability to contact and interact with the corresponding concavity of the convex surface on the movable block 3 at the time of opening the lock 1. The movable block 3 has, as shown in Fig.3, 5, 6, 8, rotating arm groove, the pitch between axes of which coincides exactly with the axes of holes 8, wherein said spring-loaded pins 9 installed.

One or more spring-loaded pins 9 are provided on the inside of the door with pins 11 that are in contact with pins 12 mounted in the lock case 1 or in its rear cover facing inward and connected to a device for transmitting an audio signal or a signal to a security control panel.

A bracket 13 is installed in the housing 2 with an opening for introducing the tail portion of the handle 5 into it and the fixing assembly 14. The locking assembly 14 consists of a rectangular insert 15 that interacts with a rotary disk 16 having rotation limiters in the housing 2 that do not allow the handle 5 to rotate . The rotary disk 16 is pivotally connected to three rods 17, the end of each of them is pivotally connected to the wedge elements 18, which, along the guide sleeve 19 installed in the housing 2 of the lock 1, can enter and exit the openings of the door frame 20. The handle 5, associated with the locking node 14, has two positions: locked or released from locking. In the latter case, it has the ability to move freely with the movable unit 3.

The lock 1 is equipped with two keys: an overhead key 21 and a flat key 22. The overhead key 21 has protruding pins 23 having different heights corresponding to the location of the concave part and the length of the spring pins 9, and the magnitude of their stroke.

Figure 10 shows an option for locking the door from the inside of the room.

Additional locking is carried out, for example, using a loop 24, worn on the inner handle 5. The loop 24 is fixed to the bracket 25 having an opening for the pin 26. A spring 27 is put on the pin.

In the case of using a lock 1 of the described design for a safe door (Fig. 10, 11), an additional door lock on the inside, for obvious reasons, is not carried out. Therefore, in FIGS. 10, 11. there is no handle, loop, or bracket with a spring-loaded pin.

The castle operates as follows.

When the lock 1 is in the locked state, the well 7 for inputting the flat key 22 is closed by the tail part 6 of the movable unit 3, and the movable unit 3 is fixed against bias by spring-loaded pins 9, which are in the upper position, as shown in Fig. 5. In this position, the springs 10 of the pins 9 are fully released. The handle 5 for opening the door is stationary and cannot be shifted even when a force is applied to it, since the insert 15 of the fixing unit 14 enters the groove of the bracket 13, the rotary disk 16 is also stationary in this state. In this case, the wedge elements 18 of the rods 17 of the fixing unit 14 are included in the door frame 20. Thus, in the closed state, the door is locked in several places: the keyhole 7 is closed, the handle 5 is locked from rotation, the fixing unit 14 motionlessly connects the lock body 2 to the door box of 20.

Opening the lock is as follows.

The overhead wrench 21 with protruding pins 23 of different heights (at least three in each row, five pins in each row in the figures) is applied to the holes 8 on the housing 2, in the holes 8 of which spring-loaded pins 9 are placed.

The wrench 21 is pressed all the way to its contact with the spring pins 9. When pressed, the spring pins 9 move inside the holes in the housing 2. Since each spring pin 9 has a concave surface at a certain distance from the end outer surface, and the movable unit 3 is aligned with spring-loaded pins 9 corresponding convex surface in the form of an annular cylindrical grooves, then when you move the spring-loaded pins 9 to the coincidence of these surfaces along the axis of the moving block handle 5 release given from fixation.

The number of ring grooves on the movable block 3 is one more than the number of spring-loaded pins 9, and the handle 5 together with the movable block 3 can be moved by the amount of stroke corresponding to the distance between the axes of the spring-loaded pins 9, which coincide with the axes of the holes 8. The movable block 3 in this position has no fixation. The handle 5, together with the movable block 3, is moved to the extreme position, its tail part 6, which is a deadbolt, is also moved, while the well 7 opens for a flat key 22, with which you can open the lock 1.

When the door handle 5 is rotated, the fixing assembly 14 is released: the insert 15 leaves the connection with the bracket 13, the rotary disk 16 is released and rotated together with the rotation of the handle 5. When the disk 16 of the fixing assembly 14 is rotated, the rods 17 are rotated together with the disk 16, since they are hinged connected to it. The wedge elements 18, pivotally connected to the rods 17, slide along the guides 19 and exit the connection with the door frame 20, freeing the door from additional fixation. Thus, the door is released from fixation, and the lock 1 can be opened by turning the flat key 22 in the keyhole 7. You can enter the room.

To fix the door from the inside from entering the room, the following must be done.

The handle 5 on the inside of the door rotates. In this case, the wedge elements 18 along the guide bushings 19 are returned to their original place, and the locking unit 14 is set to the locking position. The door cannot be opened from the outside, the handle 5 is fixed from the outside.

For additional blocking from opening the door, loop 24 is put on the handle 5, having previously been tightened by compressing the spring 27.

When using the design for the safe, there is no lock on the inside of the door. All other structural elements and the opening and closing of the lock are similar.

The described design of the lock differs from the known ones by the presence of increased secrecy means: the overhead key has different heights of the protruding pins, which does not allow you to quickly scan the surface of the lock and determine this difference and the different travel of the spring pins, especially their number of at least 3 in each row; the key hole is always closed, therefore it is impossible to reproduce the key profile; on the inside of the door there are additional locking means, described in detail, which prevent entry into the room. In addition, at the request of the owner of the room, one or more spring-loaded pins on the inside of the room can be connected to a device for transmitting an audio signal to the security control panel.

The design has enhanced security features and can be widely used in locks used for various purposes.
