The claimed invention relates to a locking device and can be used in the design of safe and household door locks, possessing a high degree of resistance in relation to criminal autopsy performed by nondestructive methods.

The invention is intended for use in castles, containing a bolt with persistent counter and set the plate delays (pins), roaming relatively resistant front of the bolt when you turn the key with a beard.

The castles of the type in question are, for example, locks, presented in the author's certificates of the USSR: [1] - SU 168141 A1, E05B 25/02, 01.01.1965; [2] - SU 370329 A1, E05B 21/02, 15.02.1973; [3] - SU 1227784 A1, E05B 25/06, 30.04.1986; [4] -SU 1481364 A1, E05B 25/00, 23.05.1989; and patents of the Russian Federation: [5] - EN 2034973 C1, E05B 35/08, 10.05.1995; [6] - EN 2174177 C1, E05B 25/00, 27.09.2001. For these locks is typical installation of plates in the guide with a possibility of a movement in the direction perpendicular to the direction of movement of the bolt. The bolt has a keyhole with the thrust areas intended for application efforts, under which the movement of the bolt, and thrust rack, interacting with . The plates have the keyhole, which is resistant hour front of the bolt, and the rounded contact the site, designed for interaction with the key. Profile configuration of hard front of the bolt and configuration figure holes in determine the lock code. The plates are biased by relatively housing castle springs, providing constant contact the pins with the key in the course of movement of the bolt. When the key is removed the plates under the action of springs are set in its original state, blocking resistant rack in figure hole levers.

During unlocking affect key levers, setting them in a working position corresponding to the code lock allows for the possibility of passing the persistent stand of the bolt through the passage in figure hole levers, as well as exerting force generated key to , exercising its move the inside lock case. Installation of plates into position and movement of the bolt perform, within any time phases, with a simultaneous force created a key levers and bolted, namely, the arched contact areas of the pins and the thrust areas of the bolt. During the movement of the bolt levers at the expense of their springs are in constant contact with the key, ensuring the free passage of hard front of the bolt through the plates. Lock locking is carried out in reverse order.

For the method of unlocking, implemented in castles [1] - [6], the principal is the simultaneous installation of plates into position and movement of the bolt, which is ensured by the simultaneous application of the efforts generated key to and .

The simultaneity of performing these operations in the castles [1] - [6] affects their resistance to criminal penetration, conducted by nondestructive methods. The reason is that inherent in this method of simultaneous access to and from a key hole, and also possibility of simultaneous they move relative to each other allow to reveal the code lock and open the lock with spikes, the action is based on the simultaneous application of effort to and .

There is a method of unlocking presented in the patent of Russian Federation [7] - EN 2387774 C1, E05B 25/02, 27.04.2010, which aims to enhance the resilience of the castle to criminal autopsy performed by nondestructive methods, due to explode in time setup operations of plates into position and movement of the bolt carried out, respectively, for the first of these operations in the conditions of mechanical blocking of movement of the bolt, and the second - in terms of prevention of access to .

Method of unlocking presented in [7], taken as a prototype.

The essence of the prototype method consists in the following. In the castle contains a bolt with a bitter stand, plates and key with the beard affect key levers, transferring them from the initial position to the working position responsible code lock allows for the possibility of passing the persistent stand of the bolt through the appropriate passages in , then fix the plates in the established working position, and then the continuous effort generated key to , exercising its move, the translation of the plates into position and fixation of levers in this position is carried out in a certain angular sector turning the key in the conditions of mechanical blocking of movement of the bolt, and, unlocking the bolt and moving it is carried out in different angular sector turning the key, where access to blocked.

An example of a castle that implements a prototype method, is the castle, described in [7, p.4 formula]. This castle contains placed in the casing and bolted with persistent counter, installed with the possibility of reciprocation in the process of unlocking and locking the castle, implemented by turning the key, and the plates, installed with the possibility of displacement relative to the persistent stand of the bolt. The bolt has a keyhole with the thrust areas intended for the efforts under the influence of the bolt slides into the housing when unlocking the lock in and out of the chassis while locking the castle. The plates have three curly holes. First of shaped holes, forms a passage for the persistent stand of the bolt - code ESD; the second has thrust a site intended for the application efforts movement, under which the plates will then be enforced by the initial position; the third has thrust a site intended for the application efforts displacement by barb key during the installation of the pins in the operating position corresponding to the code lock allows for the possibility of passing the persistent stand of the bolt through the plates. The castle also contains a revolving cylinder with a slot for key associated first gear with rotary cushion, designed to reset the pins in the initial position and the second gear with swivel leash, intended for movement of the bolt, and the protective screen, overlapping access to by the key slot in all angular sectors turning the key, except for sectors of interaction key with . Rotary leash is located in the figure bolt hole, turning the roller is located in the second figure hole of levers, a revolving cylinder in the third figure hole levers. The plates are separated from each other and housing castle friction elements, that provide the independence movement and preservation of the established provisions when the force is removed move.

Configuration figured holes of levers and deadbolt, profile rotary leash and rotary cushion, their angular position relative to the key slot rotary cylinder and ratios of gears; designed so that in the initial phase of unlocking - phase output rotary cushion of interaction with corresponding to the first angle sector turn the key towards the release, the bolt is blocked from moving turning leash and located in initial position; in the next phase unlocking - phase installation of plates in the working position, corresponding to the second angle sector turn the key towards the release, the plates are in interaction with the key, and the bolt is blocked from moving turning leash; in the next phase unlocking - phase output key of interaction with , corresponding to a third angle sector turn the key towards the release, the bolt is blocked from moving turning leash, and the plates are established in the key position, locked friction elements; in the next phase unlocking - phase unlock and began moving the bolt, corresponding to the fourth angle sector turn the key towards the release, levers are in the working position, locked friction elements, and the bolt is in conjunction with swivel leash exercising his move inside; in the final phase of unlocking - phase end of the movement of the bolt and installation of plates in the initial position, corresponding to the fifth angle sector turn the key towards the release, his final full turn, and bolted interacts with swivel leash, and the plates - with swivel roller transferring the plates from the working position in the starting position.

Thus, the method of unlocking, taken as a prototype, the operation of transfer of plates from the initial position to the working position responsible code lock, and the operation on the movement of the bolt spaced in time and are carried out in different angular sectors turning the key. Operation of transfer of plates from the initial position to the operating position is completed fixing of levers in the established working position, which is saved until a push installation of plates in the initial position. The translation of the plates into position and fixing pins in the operating position implemented mechanical blocking of movement of the bolt turning leash, and unlocking the bolt and his movement are in terms of overlap of direct access to protective screen. In aggregate, this makes the use of lock picks for the opening of the castle due to the impossibility of simultaneously to change the position of the pins and the deadbolt.

The essence of the proposed method of unlocking is that in the castle contains a bolt with a bitter stand, plates and key with the beard affect key levers, transferring them from the initial position to the working position responsible code lock allows for the possibility of passing the persistent stand of the bolt through the appropriate passages in , then fix the plates in the established working position, and then the continuous effort generated key to , exercising its move, the translation of the plates into position and fixation levers in this position is carried out in a certain angular sector turning the key in the conditions of mechanical blocking of movement of the bolt, and, unlocking the bolt and moving it is carried out in different angular sector in the conditions of the blocking of movement of plates relative to each other.

The essence of the claimed invention and the possibility of its implementation are explained illustrative materials, presented on the figure 1-11, where:

Castle implementing the proposed method, contains a body 1 box-shaped, closed the lid 2 (1, 2). In case 1 is bolted 3 with persistent stand 4, mounted with the possibility of reciprocation in the process of unlocking and locking the castle, implemented by turning 5 key one turn, and set the plate pins 6 (for example, eight levers), installed with the possibility of displacement relative to the deadbolt 3 and its obstinate stand 4 in the direction perpendicular to the direction of movement of the bolt 3 1, 2, 3, 4).

Resistant 4 hour front of the bolt is located 3 in figure hole 7 pins 6, contains a passage (code groove) for the passage of hard rack 4 (1, 3). Resistant hour 4 can be shaped profile, code lock, as it is carried out in castles, presented in [7], in this case levers 6 are the same.

The castle also contains a revolving cylinder 8 with key slot for the key 5 and a fixed leading toothed wheel 9 (1, 2).

The drive sprocket 9 is connected with the slave toothed wheel 10 actuator leash 11, intended for movement of the bolt 3, also with the slave toothed wheel 12 actuator, roller 13, intended to reset the pins 6 in the initial position, as well as with the slave toothed wheel 14 actuator Cam 15 designed for push-UPS blocker 16 from the ends of levers 6 when blocked (figure 1).

In this example the castle that implements the proposed method, the first gear, linking the revolving cylinder 8 with swivel leash 11, has a gear ratio of 1:1,6875, and the second and third gears linking revolving cylinder 8 respectively with swivel roller 13 and a Cam 15, have a gear ratio of 1:1.

Revolving cylinder in figure 8 is located hole 17 pins 6. Keyhole 17 has a thrust area of 18 for effort displacement by barb 5 key during the installation of plates 6 in the operating position corresponding to the code lock allows for the possibility of passing the persistent stand 4 through the pass of the curly holes 7 pins 6 (1, 3).

Rotary cushion 13 is in figure hole 19 pins 6, has thrust area of 20 to interact with swivel roller 13 (1, 3).

Rotary leash 11 is located in the figure hole 21 bolt 3, where two of the thrust of section 22 (221 and 222), intended for application of an effort by the rotary leash 11, under which the bolt 3 slides into the housing 1 when unlocking the lock in and out of him at closing of the castle, and the thrust of the plot 23, designed for mechanical locking bolt 3 locked in the castle by the interaction with him rotary leash 11 (1, 4, 5).

Levers 6 separated from each other and the housing 1 frictional elements of 24 (Fig. 2)ensure the independence movement of the pins 6 installing them in the operating position under the influence of the efforts of the movement generated key 5, and preservation of the established provisions when the force is removed move.

Blocker 16, designed to give a push lock move the pins 6 relative to each other, is a spring-loaded relative to the housing 1 plate with elastic plate 27, which at a certain position of the Cam 15 nestles to the ends of levers 6 with the effort exerted by the spring 28 (1, 6).

Configuration figured holes 7, 17, 19 pins 6 and figure holes 21 bolt 3, profile rotary leash 11, rotating the platen 13 and Cam 15, their angular position relative to the key slot rotary cylinder 8 is designed so that in the process of unlocking take place characteristic phase, illustrated by the scheme shown figure 7-11.

At the start position, the corresponding castle (1, 7), and bolted 3 is in the extended position and mechanically blocked from moving turning leash 11, which is located opposite to the thrust of the plot 23 figure holes 21 bolt 3; levers 6 are in the initial position, force established under the influence of the rotary cushion 13 on the thrust area of 20 figure holes 19 pins 6 and elastic strap 27 blocker 16 pressed from their ends through force generated Cam 15. This initial position of the pins 6 resistant hour 4 3 bolt is locked in curly holes 7 pins 6 (the so-called code lock).

For unlocking insert key 5 key groove rotary cylinder 8 and turn a key 5 clockwise.

During the first phase unlocking - installation phase of the pins 6 in operating position (in this example, this corresponds to the angle of the key 5 in limits from 0 up to 90 degrees), rotary cushion 13 excreted from the interaction with resistant plot 20 figure holes 19 pins 6, removing the push installation 6 in the initial position; the plates 6 are moved under the influence beard 5 key on the thrust area of 18 figured holes 17 pins 6 and bolted 3 remains locked turning leash 11, which is located in the zone of hard plot 23 figure holes 21 bolt 3 and elastic strap 27 blocker 16 remains wrung from the ends of levers Cam 6 15. Upon completion of this phase (Fig. 8) the plates 6, while in collaboration with key 5, occupy working position corresponding to the code of the castle, where the passage of hard rack 4 3 bolt through the keyholes 7 pins 6. This saves the mechanical interlocking deadbolt 3 turn the rotary leash 11, which is located in the zone of hard plot 23 figure holes 21 bolt 3 and elastic strap 27 blocker 16 is released from the ends of levers Cam 6 15.

The second phase of unlocking matches in this example corner you turn the key to 5 within 90 to 135 degrees. The beginning of this phase is characterized by key output 5 of interaction with 6 and fixing the installed operating position the pins 6 due to the action of friction elements 24. Further, in the continuation of this phase, during the change of the position of the Cam 15, elastic strap 27 blocker 16 pressed to the ends of the pins 6 firmly secured spring 28, thereby blocking move the pins 6 relative to each other. At the end of the specified operations rotary leash 11 in the process of its movement is displayed from a zone of hard plot 23 figure holes 21 bolt 3, thereby unlocking the bolt 3, and is brought to the hard section 221 figure holes 21 bolt 3 (Fig.9).

During the follow-up of the third phase of unlocking, corresponding in the example to the angle of the key 5 ranging from 135 to 315 degrees, swivel leash 11 is in force interaction with resistant plot 22 1 figure holes 21 bolt 3, by driving bolt 3 inside body 1. The levers 6 fixed friction elements of 24 in the working position and blocked from mutual move lock 16 during the previous phase, remain in working position during the entire process of movement of the bolt 3 inside body 1. The end of the third phase of unlocking (figure 10) is characterized by the completion of the movement of the bolt 3 the inside of the case 1, unlocking the pins 6 as a result of assignment of the locking device from 16 pins 6 (i.e. as a result of squeezing the elastic linings 27 from the ends of levers 6 by force generated Cam 15) and the tabulation of rotary cushion 13 hard to section 20 figured holes 19 pins 6 for follow-forced installation in the initial position, carried out at the final (fourth) stage unlocking.

In castle (11) and bolted 3 inside body 1, elastic strap 27 blocker 16 is released from the ends of the pins 6 and themselves levers 6 interact with swivel roller 13, install them in the initial position. Key 5 also is at the home position, caused by the completion of a full turn of 360 degrees. In this position, the 5 key can be removed from the key slot rotary cylinder 8.

For further lock key 5 key is inserted into the groove of the rotary cylinder 8 and turns counterclockwise. Operations occurring in the lock, repeat in reverse order to the above phases and operations, which occur when unlocking the lock, and, in contrast to the release, rotary leash 11 interacts with resistant plot 22 figure 2 holes 21 3 bolt.

Thus, in the present method unlocking operation of transfer of plates 6 of the initial position to the working position responsible code lock, and the operation on the movement of the bolt 3 spaced in time and are carried out in different angular sectors turning the key. Operation of transfer of plates 6 of the initial position to the working position finishes fixing pins 6 in the working position due to the action of friction elements 24 and this position is saved until a push installation of plates in the initial position. These transactions related to the transfer of plates 6 of the initial position and their fixation in the working position is carried out in conditions of mechanical blocking of movement of the bolt 3 turn the rotary leash 11, and the subsequent unlocking the bolt 3 and moving it into the casing 1 is carried out in a block move the pins 6 relative to each other blocker 16. In aggregate, this makes application of any lock picks for the opening of the castle due to the inability to carry out controlled (unmistakable attached impact) change the position of the pins 6 when resistant hour 4 3 bolt hinges when moving the bolt 3 in the side of the slot code groove pins 6.

This shows that the claimed invention is feasible, its implementation has the effect of increasing resistance of the castle to criminal autopsy performed by nondestructive methods, and provides solution of the tasks for extension of technical means for this purpose.
