Description

SHCHDROVOE yCIPOECTBO LH LOCK

The proposed utility model relates to security objects and can be used in locking and locking devices of safes, apartments, garages .. Numerous designs are known, the so-called English locks and keys to them (1,2,3,4,5,6), containing a cylinder mechanism having a housing with spring-loaded pins and coded pins directly in the cylinder, and the spatial combination of these pairs of pins determines the shape of the key for unlocking the lock.

Such designs have low secrecy, because they make it possible by means of master keys to probe through the keyhole the number, sizes and amount of movement of the code pins / located in the initial state above the corresponding sub-prudent pins, or simply enter quickly into the keyhole the hardening mixtures that take the form of a key.

A common disadvantage of these devices is that the channel for entering keys remains unapproved from unauthorized penetration of the master key and ringing of the internal device of the lock.

The closest in technical, in essence to the claimed device is the lock (7) selected as a prototype, containing two lines of spring-loaded pins and code pin diametrically located in the housing) with two rows of code pins in contact with the corresponding spring-loaded pins ..: -.

IShOB, B27 / 04 ;;. B35 / IO ;: B37 / I2; BI3 / 04; BI9 / IO; BI9 / I6; .BI9 / I8

This design somewhat increases the degree of security to certain limits by increasing the number of pairs of code and spring pins 0 use to encode both sides of the key.

However, this prototype design has the same drawback: the key input channel is insecure from studying the internal structure of the mechanism of any kind of master keys.

The claimed object also contains a housing with a number of spring-loaded pins, a cylinder, bearing code pins interacting with the corresponding spring pins and a key with a line of cuts for code pins. However, a sleeve with its spring loaded from between the cylinder and the housing outside the area of their pins is additionally inserted the center to the periphery of the code, and the code pins of the sleeve when turning the cylinder are opposite the additional spring-loaded housing and at an angle to the axis of the known pairs of pins Comrade, in the area where additional pins are located on the code cylinder, a cutout is made, a stopper is installed in the sleeve, and the code line of key cutouts is enlarged in length and its additional part corresponds to the code values of the additional sleeve.

Technical advantages of the claimed object in comparison with known devices are as follows:

-Introduction of the intermediate sleeve with its spring-loaded code, interacting in a certain way with additional spring-loaded housing pins;

-Specified spatial arrangement of interacting pairs of pins, providing sequential unlocking cylinder Vdrulka, sleeve-housing;

- changing the design of the key, the cut-out code line of which is increased in length and its additional part corresponds to the code values of the pins of the additional sleeve.

The combination of these technical advantages of the claimed object provides a positive effect, which consists in a significant increase in the secrecy of the mechanism.

Figure 1 shows a diagram of the operation of the cylinder device for locks on figure 2; its section is AA, in figure G.Z along BB, figure 4 shows the same section along BB, but the cylinder is rotated 90 ° , Fig. 5 shows a section BB showing the placement of the stopper.

The cylinder locking device comprises a housing I, a cylinder 2 directly connected to the lock bolt by a leash 3. The cylinder contains its code pins 4, working radially paired with spring-loaded pins 5 of the housing. Between the walls of the housing and the cylinder, outside the zone of location of the pins, an additional sleeve 6 is inserted with its coded spring-loaded pins 7 located opposite the additional spring-loaded pin of the housing 8, the latter being located, for example, at an angle of 90 to the axis of the location of the pins 4-5 . A cutout 9 is made in the area of the sleeve’s location on the code cylinder, and a stopper 10 is installed in the sleeve, which restricts the rotation of the cylinder to the B-axis during rotation of the key II. The key has two code lines of cut-outs I and P. The return to the initial closed position is carried out, for example, by a spiral spring 12 fixed between the leash and the body, or by a horizontal lock bolt spring (not shown in Fig.).

The cylinder lock device operates as unlocked as follows.

After entering the key II into the bore of the cylinder 2 (see Fig. 1 and FIG. 2), the code pins 4 are moved, one of the ends of which abut against the code ledges of the key, and the other ends of them are installed in a line along the Generator of the cylinder with the ends of the spring pins 5, in this case, the cylinder is unlocked and can be turned by further turning the key relative to the housing. This is the standard scheme of operation of typical English locks in which the code pins are passive and the pins located in the case are spring-loaded to the center.

In the proposed device (FIG. 3), the coded spring-loaded pins 7 initially block the sleeve 6 relative to the housing I, therefore, it is stationary. Even if the attacker picked up the English code line I of key cut-outs, the latter can only make oscillatory movements limited by the stopper 10. The values of the cut-outs, code line P are set by the size of the code pins 7 and the thickness of the sleeve, however these pins are located at an angle, for example, 90 and are not available for keying through a keyhole

IF you have your own key, then further turning it clockwise (view from the side of the key input, see Fig. 4 and Fig. 5), the cylinder 2 cuts out 9 along the b-axis along the stopper 10, while the cut-outs of the code line P of the key II are located opposite the code pins 7 and additional pins of the housing 8. Since the prudent pins 8 are stronger (rigid), then the opposite ends of the code pins 7 will be pressed against the key II, and the contact end surfaces of the pins 7 and 8 will be located around the contact circumference of the sleeve 6 and housing I and thus the sleeve relates It is completely unlocked. With further turns of the key, cylinder 2 will rotate together with the sleeve 6 and, through the leash 3, act on the lock deadlock. After an integer number of revolutions on unlocking the lock and opening the doors, the device returns to the position shown in FIG. 4. However, the pins 4, displaced relative to the pins 5, do not allow the key to be pulled out of the squadron in this position, therefore, the key should be turned back 90 and pulled out in the position of FIG. closing the door leash 3 with the bolt to its original position.

In various designs of this device, the location of the interacting pairs of pins 4-5 and 7-8 can be. At an angle other than 90 °, as well as the structural arrangement of the elements. In particular, the number of pairs of pins can be increased and code cutouts can be applied to the second side of the key. However, these decisions are known and, according to the authors, are not subject to patenting.

The principle of the proposed solution from known similar devices is the lack of the ability for a thief-malefactor to pick out the internal device of the mechanism, the location and amount of movement of the code pins 7. With a master key, in case of a standard approach to a typical English lock, the code pins 4, and having made part I of key II, the attacker has the ability to turn the cylinder 2 only within 90 °, and the sleeve 6 is not unlocked. At the same time, the attacker shuts the well for himself with this key to examine the pins 7, which are displaced in space.

Indicated your design differences allow you to create a new class of locks of high security.

. The use of this mechashism significantly increases the secrecy (reliability) of locks and locking devices without any additional costs and complex technologies.
