Method for lock unlocking and lock that realises this method

FIELD: construction.

SUBSTANCE: method for unlocking of lock consists in the fact that changing levels from initial position into working one, which complies with the lock code, ends with fixation of levels in specified working position, at the same time changing levels into working position and fixation of levels in this position is executed in a certain angular sector of key turn under conditions of mechanical blocking of latch motion, and latch unlocking and its displacement is carried out in another angle sector of key rotation, where access to levels is closed. To execute these operations, locks comprises mechanisms of displacement and mechanical blocking of latch and installation of levels into initial position, and also protective screen that closes access to levels from outside in certain angle sectors of key rotation.

EFFECT: improved resistance of locks to criminal opening performed by non-destructive check methods.

The claimed group of inventions relates to locking devices and can be used in the development of a safe and residential door locks, possessing a high degree of resistance against criminal autopsy carried out by non-destructive methods.

The claimed invention are intended for use in locks containing dead bolt thrust stand and the set plate latency (levers)that is moved relative to the thrust stand bolt when turning the key with a beard.

The locks of this type include, for example, castles, presented in copyright certificates of the USSR: [1] - SU 168141 A1, EV 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, 25/00 E05B, 23.05.1989; and patents of the Russian Federation: [5] - EN 2034973 C1, E05B 35/08, 10.05.1995; [6] - EN 2174177 C1, 25/00 E05B, 27.09.2001. For these locks typical installation of the pins in the guide with the possibility of their displacement in the direction perpendicular to the direction of movement of the bolt. The bolt is shaped hole with thrust areas designated for force interaction with the key, and resistant rack, interacting with the levers. Levers have keyholes, which is resistant strut bolt and curved sections, designed for interaction with a key. Profile configuration of the thrust stand bolt and the config is the situation figured holes in the levers define a lock code. In the process of unlocking and locking the lock levers are installed in working position, corresponding to the code lock, which allows the passage of the thrust stand bolt through the levers, and the bolt is applied, the displacement force, under the action of which upon unlocking of the lock bolt slides into the lock case, and when locking the lock - out of the chassis to Install the pins into position and move the bolt to happen within the same temporal phase, and the key simultaneously affects his beard on the pins inside the lock and the bolt, namely, the arcuate contact sections of the levers and the thrust areas of the bolt. During movement of the latch levers due to its springs are in constant contact with the key, allowing for the free passage of the thrust stand bolt through the keyholes of levers. When the key is removed levers under the action of the springs are set in the initial state, blocking the thrust stand in curly holes levers.

On this same principle working one-turn locks with plate swivel levers that are moved under the action of the key in the angular direction simultaneously with the longitudinal movement of the bolt, see, for example, U.S. patents: [7] - US 4462230, 25/00 E05B, 31.07.1984; [8] - US 5502990, 25/00 E05B, 02.04.1996; [9] - US 1935225, US C1, 70-75, 14.11.1933. Levers in these locks installed on the same axis BP is tion with the possibility of angular displacement under the action of the key, have turned to thrust the rack bolt slot made in a radial direction relative to the rotation axis, and arcuate contact areas to interact with the key. Profile configuration of the thrust stand bolt and angular position of the slots of plates define a lock code. In the locked condition of the lock levers under the action of their springs are in an extreme angular position, blocking the ability to move the bolt into the lock case. Unlocking and locking of the lock is effected by turning the key in the locks [7] and [8] the force transmission from the key to the deadbolt is realized by means of an intermediate element that performs the function of the lever and in the castle [9] has a direct interaction with key bolt. In castles [7]-[9], as in the above locks [1]-[6], the installation of levers in operating position, corresponding to the code lock, and move the bolt is part of one temporary phase, while the levers due to its springs are in constant contact with the key, allowing for the free passage of the thrust stand bolt through the levers. When the key is removed levers under the action of its springs are in the initial position, blocking the possibility of movement of the bolt.

As a prototype of the claimed inventions adopted the design and method of unlocking, Rea is isawanya in the castle, presented in U.S. patent [10] - US 3884058, E05B 21/00, 20.05.1975.

Lock-prototype contains accommodated in the housing and bolted to the thrust stand, mounted with the possibility of reciprocation in the process of unlocking and locking the lock by means of turning the key, set the plate of levers mounted for movement relative to the thrust stand bolt, and a key with a beard, inserted into the castle through a corresponding key slot in the housing. Levers mounted on the axis of rotation, spring-loaded relative to the body, have figured slots with arcuate contact section that is meant to interact with the bit of a key, and a passage intended for the passage of the thrust stand bolt. The bolt is shaped hole with thrust areas designated for the efforts of the movement generated by the key under which the bolt is pushed into the housing at the opening of the lock in and out of the housing when the locking of the lock. Profile configuration of the thrust stand bolt and the location of the openings in the levers define a lock code. In the locked state of the lock bolt extended, the key is removed) levers under the action of its springs are in the extreme corner (initial) position, in which the position of openings in the levers not souped the em with the position of the thrust stand, thereby providing a code lock bolt.

During unlocking influence key levers, setting them into position responsible code lock, which allows the passage of the thrust stand bolt through the passages in the figure the slots of the levers, as well as exerting force created by the key, the bolt, making it move inside of the castle. Install the pins into position and movement of the bolt is carried out in the framework of one temporal phase, and the key simultaneously affects his beard on the pins inside the lock and the bolt, namely, the arcuate contact sections of the levers and the thrust areas of the bolt. During movement of the latch levers due to its springs are in constant contact with the key, allowing for the free passage of the thrust stand bolt through the levers. The locking of the lock is carried out in reverse order.

Thus, in the prototype, as in the above analogues [1]-[9], there is a simultaneous setting of levers into position and movement of the bolt, which is ensured by the simultaneous application of force generated by the key to the levers and bolt.

The simultaneity of these operations affects the durability of the lock-prototype against criminal intrusion. The thing is that with this method otpion is I lock principle is the possibility of simultaneous access to the bolt and the levers from the side of the key hole, as well as the possibility of their simultaneous movement relative to each other, which makes it possible to identify key code to open the lock using the master keys, the action of which is based on the simultaneous application of force to the bolt and levers. Also facilitates criminal opening the door almost linear nature of the movement of levers, depending on the efforts made, due to the lever action of the spring, which allows controlled movement of levers picks.

As measures designed to some extent hamper the ability of criminal intrusion through lock picks, lock design of the prototype are teeth made on the levers. Due to these teeth are simulated false positions of levers when manipulating picks, which increases the time of opening the lock, however, these measures are not enough to fundamentally solve defend the castle from criminal intrusion.

The technical result, the achievement of the aims of the invention is to increase the resilience of locks for criminal autopsy carried out by non-destructive methods.

The essence of the proposed method of unlocking is that in the castle, containing the dead bolt thrust stand, the pins inside the lock and key with a beard, put key on souval the water, transferring them from the initial position into the operating position, corresponding to the code lock, which allows the passage of the thrust stand bolt through the appropriate openings in the levers, and exerting force created by the key, the bolt, making it move. Unlike the prototype, the transfer levers from the initial position to complete the fixation of the pins in the prescribed working position, the transfer levers into position and fixing the pins in this position perform in a certain angular sector of rotation of the key in the mechanical locking movement of the bolt and releasing the latch and moving it to perform in a different angular sector of rotation of the key, where access to the levers closed.

The essence of the castle, which implements the inventive method in a variant of safe lock, is as follows. The castle contains accommodated in the housing and bolted to the thrust stand, mounted with the possibility of reciprocation in the process of unlocking and locking the lock by means of turning the key, and levers, mounted for movement relative to the thrust stand bolt. The bolt is shaped hole with thrust areas designated for effort, under the action of which the bolt slides inside cor the USA with the opening of the lock in and out of the housing when the locking of the lock. The levers have a passage for hard rack bolt and thrust area for the application efforts move from barb key during installation of levers in operating position, corresponding to the code lock, which allows the passage of the thrust stand bolt through the levers. Unlike the prototype, the castle contains a transfer mechanism and a mechanical lock bolt and install the pins in the initial position, made in the form prescribed in figure the bolt hole and figured the slots of the levers rotatable cylinder with a key groove for placing key emphasis to interact with levers and leash to interact with the bolt, and a protective shield blocking access to the levers from the side of the key slot in the latter, while the opening of the lock angular sector of rotation of the key. The levers are separated from each other and the housing of the friction elements in the independence movement and maintaining the set position when the force is removed move. Curly slotted levers having a passage for hard rack bolt and thrust area for the application efforts move from barb key, are also resistant site intended for effort by focusing rotary cylinder when installing the plates in initial position, but figured reject the tie bolt has a thrust area, designed for interaction with the leash rotary cylinder when performing mechanical lock bolt. The mutual angular position of the key groove of the drive and stop of the rotary cylinder, and the profile of the leash rotary cylinder and configuration keyholes bolt and shape of the slots, the pins are designed so that in the first stage unlocking - phase output of the focusing rotary cylinder out of engagement with the levers corresponding to the first angular sector of rotation of the key, the bolt is blocked from moving leash rotary cylinder and levers, located at the home position; in the second phase of the unlocking - phase installation of levers in operating position corresponding to the second angular sector of rotation of the key levers are in interaction with the key, and the bolt is blocked from moving leash rotary cylinder; in the third phase of the unlocking - phase output key from engagement with the levers corresponding to the third angular sector of rotation of the key, the bolt is blocked from moving leash rotary cylinder and levers are in accordance with the key position, the fixed friction elements; in the fourth phase of the unlocking of the lock phase unlock and move the bolt corresponding to the fourth from the business sector rotation key levers are in the working position, a fixed friction element and the thrust stand, located in the aisles shaped slots of levers, and the bolt is in engagement with a collar rotatable cylinder carrying out its movement into the case. In the first phase lock corresponding to the reverse rotation of the key in the fourth angular sector, the levers are in the working position, the fixed friction elements and hard stand in the aisles shaped slots of levers, and the bolt is in engagement with a collar rotatable cylinder carrying his nomination from the case; in the second phase lock corresponding to the reverse rotation of the key in the third angular sector, extended bolt locked leash rotary cylinder and levers are in the working position, the fixed friction elements; in the third phase lock corresponding to the reverse rotation of the key in the second angular sector, nominated the bolt is locked leash rotary cylinder and levers are in the working position; in the fourth phase lock corresponding to the reverse rotation of the key in the first angular sector, extended bolt locked leash rotary cylinder and levers are in interaction with emphasis on Oronogo cylinder, carrying out the installation of levers to their initial position.

In some cases, of the execution of this castle first angular sector corresponds to the angle of rotation of the key and the rotary cylinder in the range from 0° to 30°, the second angular sector corresponds to the angle of rotation of the key and the rotary cylinder in the range from 30° to 100°, the third angular sector corresponds to the angle of rotation of the key and the rotary cylinder in the range from 100° to 120°, and the fourth angular sector corresponds to the angle of rotation of the key and the rotary cylinder in the range from 120° to 160°.

The essence of the castle, which implements the inventive method variant household door lock, consists in the following. The castle contains accommodated in the housing and bolted to the thrust stand, mounted with the possibility of reciprocation in the process of unlocking and locking the lock by means of turning the key, and levers, mounted for movement relative to the thrust stand bolt. The bolt is shaped hole with thrust areas designated for effort, under the action of which the bolt is pushed into the housing at the opening of the lock in and out of the housing when the locking of the lock. The levers have a passage for hard rack bolt and thrust area for the application efforts move from barb key during the installation process wvalid in working position, responsible code lock, which allows the passage of the thrust stand bolt through the levers. Unlike the prototype, the castle contains a rotary cylinder with a key groove for dvuhnitochnogo key associated first gear with a rotary platen, designed to reset the pins in the initial position, and the second gear with swivel leash, intended to move the bolt, and a protective shield blocking access to the levers from the side of the key slot in all angular sectors of turning the key, except for the sectors of the interaction of the key levers. Swivel leash is located in curly hole bolt, thrust areas which are intended to interact with swivel leash. The rotary platen is located in the appropriate shape holes plates with thrust area for interaction with a rotary platen. The rotary cylinder is located in the appropriate shape holes plates with thrust area for interaction with the bit of a key. The levers are separated from each other and the housing of the friction elements in the independence movement and maintaining the set position when the force is removed move. The configuration of the shaped holes the pins and the bolt, the profile swivel leash and p is the gate roller, their angular position relative to the key slot of the rotary cylinder, and gear ratio gears are designed so that in the first stage unlocking - phase output rotary roller from engagement with the levers corresponding to the first angular sector of rotation of the key in the direction of firing, the bolt is locked against rotary movement by the leash, and levers, located at the home position; in the second phase of the unlocking - phase installation of levers in operating position corresponding to the second angular sector of rotation of the key towards unlocking the levers are in interaction with the key and the bolt is locked against rotary movement by a leash; the third phase of the unlocking - phase output key from engagement with the levers corresponding to the third angular sector of rotation of the key in the direction of firing, the bolt is locked against rotary movement by the leash, and the levers are in accordance with the key position, the fixed friction elements; in the fourth phase of the unlocking of the lock phase unlock and begin to move the bolt corresponding to the fourth angular sector of rotation of the key towards unlocking the levers are in the working position, the fixed friction elements, and the bolt is in engagement with povorotny leash, exercising its movement inside; in the fifth phase of the unlocking phase of the end of the movement of the bolt and install the pins in the initial position corresponding to the fifth angular sector of rotation of the key in the direction of unlocking, his final full rotation, the bolt interacts with swivel leash, and levers - with a rotary platen, moving the levers from the operating position to the initial. In the first phase lock the phase of the output rotary roller from engagement with the levers corresponding to the first angular sector of rotation of the key in the direction of the locking levers are in the initial position, the fixed friction elements; in the second phase lock phase installation of levers into position and begin to move the bolt corresponding to the second angular sector of rotation of the key in the direction of the locking levers are in interaction with the key and the bolt is in interaction with swivel leash exercising his nomination from the case; in the third phase lock phase displacement of the bolt corresponding to the third angular sector of rotation of the key towards unlocking the levers are in accordance with the key position, the fixed friction elements, and the bolt is in interaction with swivel leash, realizing the m its movement from the housing; in the fourth phase lock the phase of the beginning of the lock bolt corresponding to the fourth angular sector of rotation of the key toward the lock, extended bolt contacts with swivel leash exercising its mechanical lock and levers are in the working position, the fixed friction elements; in the fifth phase lock phase installation of levers to their initial position corresponding to the fifth angular sector of rotation of the key toward the lock, his final full turn in the opposite direction, the levers are in cooperation with a rotary platen, moving the levers from the operating position to the initial and extended bolt is locked against rotary movement by the leash.

In some cases, of the execution of this castle first angular sector of rotation of the key in the direction of firing is in the range from 0° to 45°, the second angular sector of rotation of the key in the direction of firing is in the range from 45° to 90°, the third angular sector of rotation of the key in the direction of firing is in the range from 90° to 180°, the fourth angular sector of rotation of the key in the direction of firing is in the range from 180° to 315°, the fifth angular sector of rotation of the key in the direction of firing is in the range from 315° to 360°, the first angular sector of rotation the key toward the lock is within the Ah from 360° to 315°, the second angular sector of rotation of the key toward the lock is in the range from 315° to 270, the third angular sector of rotation of the key toward the lock is in the range from 270° to 90°, the fourth angular sector of rotation of the key toward the lock is in the range from 90° to 45°, the fifth angular sector of rotation of the key toward the lock is in the range from 45° to 0°. The first gear train connecting the rotary cylinder with a rotary platen, has a gear ratio of 1:1, and the second gear train connecting the rotary cylinder with swivel leash is a reduction gear with a gear ratio of 2:1. Levers mounted with capability of their movement in the direction perpendicular to the direction of movement of the bolt, while the function of the guides for the pins meet the protective screen and the cylindrical strut, which forms the axis of rotation of the leash.

The principal difference between the proposed method and castles implementing the inventive method, the prototype and its analogues is that the unlocking of the lock operation to transfer the pins from the initial position into the operating position, corresponding to the code of the castle, separated in time from surgery to move the bolt and is completed by fixing the pins in the prescribed working position. In the phase of the transfer levers from the initial paragraph the provisions in the work cannot move the bolt due to its mechanical lock, and in the phase unlock and move the bolt is blocked direct access to the levers. Together this makes fruitless use of master keys for opening the door because of the impossibility of simultaneously changing the position of the pins and the bolt.

Safe lock (Fig.1-6) includes a housing 1 box of odds with the side walls 2 and a lid 3 (Fig 1, 2, 3). The cover 3 is made of the key hole 4 to set key 5 with a beard. In the housing 1 are a bolt 6 with persistent counter 7 (Fig 1, 2, 4), mounted with the possibility of reciprocation in the process of unlocking and locking the lock, and set the plate of levers 8, for example, six levers 8 (1, 2, 5), mounted on a common axis 9 can be rotated around it and longitudinal movement along it.

The castle is also provided with a transfer mechanism and a mechanical lock bolt 6 and the installation of levers 8 in the initial position, made in the form of a rotary cylinder 10 with the key groove 11 for placement of the key 5, the stop 12 to communicate with the levers 8 and leash 13 for engagement with the bolt 6 (Fig 1, 2, 6). The rotary cylinder 10 is curved slots 14 of levers 8 (figure 5) and figured the hole 15 of the bolt 6 (figure 4) can be rotated about its own axis, while its lower part is located in the cylindrical recess 16, is made in the bottom of the casing 1, and the upper part is located in a cylindrical recess 17, is made in the cover 3 (Fig 1, 3).

Figo is a great hole 15 in the bolt 6 (figure 4) has thrust areas 18 and 19, designed for the efforts on the part of the leash 13, under the action of which the bolt 6 is pushed into the housing 1 at the opening of the lock in and out of him by locking the lock, and the thrust portion 20, interacting with the lead 13 when performing mechanical lock bolt 6 in the locked castle (2, 7).

Figure slits 14 in the levers 8 are passage 21, intended for the passage of the thrust of the rack 7, and the thrust areas 22 and 23 (figure 5). Thrust area 23 is designed for application efforts on the part of the stop 12 when installing the pins 8 in the initial position, in which the position of the passages 21 in the levers 8 does not coincide with the position of the thrust front 7, which provides a code lock bolt 6 (2, 7). The thrust section 22 is designed for application efforts move from the barb of the key 5 in the installation process of levers 7 in the operating position, corresponding to the code lock, which allows the passage of the thrust front 7 through levers 8 (Fig, 9, 10).

Levers 8 are separated from each other and the housing 1 of the friction elements 24, ensures the independence of their movements, in particular when mounted in operating position upon application of force move on the part of the key 5, and maintaining the set position when the force is removed move.

The friction elements 24 within the s in the form of a wear-resistant spacers, for example, made of bronze, mounted on the axis 9 (Fig 1, 2). The friction elements 24 is locked against rotation around the axis 9 due to the emphasis in the wall 2 of the housing 1, the ability of free movement of the friction elements 24 along the axis 9.

The levers 8 and the friction elements 24 are pressed to each other by a force generated by a cylindrical spring 25 fixed on the axis 9 (Fig 1), which provides creating the necessary friction forces.

In this example, persistent hour 7 (1, 2, 4) is made in the form of a set of plates arranged on top of each other with the formation of curved profile corresponding to the code lock, the levers 8 are the same (with the same shaped slits 14).

The castle also has a protective screen 26, is made in the form of a segment of a hollow cylinder, mounted on the cover 3 (2, 3) and blocking access to the levers 8 from the key slot 11 in the past, when unlocking the lock, the angular sector of rotation of the rotary cylinder 10 (figure 10), in which there is no mechanical lock bolt 6 leash 13.

The profile of the lead 13, the mutual angular position of the key groove 11, the lead 13 and the stop 12 of the rotary cylinder 10, and the configuration of the shaped holes 15 of the bolt 6 and figure of the slots 14 of levers 8 are designed so that in the process of unlocking and subsequent C is pirania lock key 5 and accordingly, the rotary cylinder 10 is held in its angular movement across the four angular sector of rotation, corresponding to the four typical phases of unlocking and locking the lock, as illustrated by the scheme shown in Fig.7-10.

In the initial position corresponding to the locked castle (2, 7), the bolt 6 is in its extended position and is mechanically locked from movement of a lever 13, which is located opposite to the thrust portion 20 shaped openings 15 of the bolt 6 and the levers 8 are in the initial position, force established under the influence of the stop 12 to thrust a site figure 23 of the slots 14 of levers 8.

Unlock the lock as follows. Through the key hole 4 of the cover 3 insert the key 5 in the key groove 11 of the rotary cylinder 10 and turn the key 5 and, accordingly, the rotary cylinder 10 in the direction corresponding to opening of the lock (in this example, clockwise).

In the first phase of unlocking the phase lock 12 from engagement with the levers 8, corresponding to the first angular sector of rotation of the key 5 and the rotary cylinder 10 (in this example, this corresponds to the rotation angle ranging from 0° to 30°), the bolt 6 is in its extended position and is locked against movement by the lead 13 and the levers 8, which is the initial position. In the process of implementing the first phase of unlocking the stop 12 is withdrawn from contact with the levers 8, and the bit of a key 5 is applied to the thrust areas 22 of curved slots 14 of levers 8.

In the second phase of the unlocking - phase installation of levers 8 in the operating position corresponding to the second angular sector of rotation of the key 5 and the rotary cylinder 10 (in this example, this corresponds to the rotation angle ranging from 30° to 100°), the levers 8 are in collaboration with key 5, influencing his beard on thrust areas 22 of curved slots 14 of levers 8, and the bolt 6 is blocked from moving leash 13 (Fig). Under the force of movement generated by the key 5, the levers 8 are installed in working position, corresponding to the code of the lock, thereby providing the possibility of passing the thrust of the rack 7 through the passages 21 in the levers 8. Thus, in the process of implementing the second phase of the unlocking operation is implemented to transfer the pins 8 from the initial position into the operating position, and this operation is performed by mechanically locked bolt 6 leash 13.

The third phase of the unlocking - phase output key 5 from engagement with the levers 8 corresponds to the third angular sector of rotation of the key 5 and the rotary cylinder 10 (in this example, this phase with the et angle in the range from 100° to 120°). In the implementation of this phase, the key 5 is withdrawn from engagement with the levers 8 while maintaining the mechanical lock bolt 6 by a lead 13, which is supplied from the thrust area figure 18 holes 15 of the bolt 8, and at the same time, fixing the set key 5 in the working position of levers 8 by the action of the friction elements 24. Thus, at the end of the third phase of unlocking the bolt 6 remains locked a collar 13, which is connected to the thrust area figure 18 holes 15 of the bolt 6 and the levers 8 are in the working position, the fixed friction elements 24, and lack of interaction with key 5 (Fig.9).

In the fourth phase of the unlocking of the lock phase unlock and move the bolt 6, the corresponding fourth angular sector of rotation of the key 5 and the rotary cylinder 10 (in this example, this corresponds to the rotation angle in the range from 120° to 160°), the levers 8 are in the working position, the fixed friction elements 24 and the thrust stand 7 included in the passages 21 of curved slots 14 of levers 8, and the bolt 6 is unlocked and is in cooperation with a collar 13 which move inside the housing 1 due to the force applied to the thrust section 18 keyholes 15 bolt 6. Feature in asanoha move the bolt 6 is it is carried out in the absence of direct access to the levers 8 from the key slot 11 by a protective screen 26. Protective screen 26 in this angular sector prevents direct access to the levers 8 from the outside, making it impossible controlled uniquely identifiable with the accompanying impact) change their position with any of the picks.

The end of the fourth phase of the unlocking corresponds to unlock the lock. In the position corresponding to the unlocked lock, the bolt 6 vdvinul inside of the housing 1, the thrust section 19 of his curly hole 15 is located in front of the lead 13, the levers 8 are in the working position, the fixed friction elements 24 and the thrust stand 7 included in the passages 21 of curved slots 14 of levers 8, and the switch 5 is located in the key groove 11 of the rotary cylinder 10 (figure 10).

Lock lock by turning the key 5 and, accordingly, the rotary cylinder 10 in the opposite direction.

In the first phase lock corresponding to the reverse rotation of the key 5 and the rotary cylinder 10 in the fourth angular sector, the levers 8 are in the working position, the fixed friction elements 24 and the thrust stand 7, in the passages 21 of curved slots 14 of levers 8, and the bolt 6 is in interaction with the about the ohms 13, exercising his nomination from the housing 1 due to the force applied to the thrust of the plot figure 19 holes 15 of the bolt 6.

In the second phase lock, the corresponding reverse turning of the key 5 and the cylinder 10 in the third angular sector put forward by the bolt 6 is blocked by a leash 13, included in the zone of contact with the thrust portion 20 of his curly slits 15 and the levers 8 are in the working position, the fixed friction elements 24 (Fig.9).

In the third phase lock corresponding to the reverse rotation of the key 5 and the rotary cylinder 10 in the second angular sector, nominated by the bolt 6 is blocked by lead 13 and the levers 8 are in the working position (Fig).

In the fourth phase lock corresponding to the reverse rotation of the key 5 and the rotary cylinder 10 in the first angular sector, nominated by the bolt 6 is blocked by lead 13 and the levers 8 are in engagement with the stop 12 of the rotary cylinder 10, transferring the pins 8 from the operating position to the initial due to the impact on thrust areas 23 of curved slots 14 of levers 8 (Fig.7). At the end of this phase, the key 5 is removed from the lock.

Thus, unlike the prototype, when the vehicle is unlocked considered a lock operation to transfer the pins 8 from the initial position into the operating position, corresponding to the code for the ka, separated in time from surgery to move the bolt 6. In the phase of the transfer plates 8 from the initial position into the working position, it is impossible to move the bolt 6 as a result of its mechanical lock leash 13, and in the phase unlock and move the bolt 6 access to the levers 8 are covered by a screen 26, which makes fruitless use any picks for opening the door due to the inability to simultaneously controlled uniquely identifiable with the accompanying impact) changing the position of the levers 8 and bolt 6. All this significantly increases in comparison with the prototype, the resistance is considered a lock to criminal autopsy.

Household door lock (11-17) includes a housing 27-shaped, closed the lid 28.

Hour 47 is located in the slots 48 of levers 32 (11, 14), fulfilling the function of the second guide levers 32. Turning the lead 41 is located in curly hole 49 of the bolt 29 (11, 13), which has two hard section 50 (right and left), designed for the application of effort on the part of the swivel leash 41 under the action of which the bolt 29 is pushed into the housing 27 at the opening of the lock in and out of him by locking the lock, and also a persistent area 51, designed for mechanical lock bolt 29 is in the locked castle, carried out through the interaction of the swivel leash 41 with thrust area 1.

Rotary roller 39 is located in the groove 52 of the bolt 29 (11, 13) and figured the holes 53 of levers 32 (11, 14)having a thrust area 54 for engagement with a rotary platen 39.

The levers 32 are separated from each other and the housing 27 of the friction elements 55 (11, 12)ensuring the independence movement of levers 32, in particular, when mounted in operating position under the influence of the efforts of the movement generated by the key 31, and maintaining the set position when the force is removed move.

Friction elements 55 is made in the form of a wear-resistant plates, for example made of bronze, mounted on a cylindrical rack 47 with a possibility of free movement along it. The necessary friction force between the levers 32 and friction elements 55 is provided compressive their cylindrical spring 56 mounted on the cylindrical rack 47 (Fig).

The configuration of the shaped holes 33, 44, 53 levers 32 and shaped openings 49 of the bolt 29, the profile swivel leash 41 and the rotary roller 39, their angular position relative to the key slot 36 of the rotary cylinder 35 is designed so that in the process of unlocking and locking the lock are five characteristic phases unlocking and five characteristic phases lock (see diagram in Fig-21).

In the initial position - position the Institute, the corresponding locked the castle (11, 18), the bolt 29 is in its extended position and is mechanically locked against rotary movement by a lead 41, which is located opposite the thrust area 51 shaped hole 49 of the bolt 29 and the levers 32 are in the initial position, force established under the influence of the rotary roller 39 on the retaining section 54 figure of holes 53 of levers 32, which is a code lock bolt 29 by blocking his thrust hours 30 figure holes 33 of levers 32.

To unlock the lock insert the key 31 in the key groove 36 of the rotary cylinder 35 and turn the key 31 in a clockwise direction.

In the first stage unlocking - phase output rotary roller 39 from engagement with the levers 32, corresponding to the first angular sector of rotation of the key 31 in the direction of unlocking (in this example, this corresponds to the rotation angle ranging from 0° to 45°), the bolt 29 is locked against rotary movement by a lead 41 and levers 32, which in the initial position (11, 18). In the process of implementing the first phase of the unlocking rotary platen 39 is withdrawn from contact with hard parts 54 of levers 32, and the bit of a key 31 is supplied to the thrust section 45 of curved slots 44 of levers 32.

In the second phase of the unlocking phase of installation is key levers 32 in the operating position, corresponding to the second angular sector of rotation of the key 31 in the direction of unlocking (in this example, this corresponds to the rotation angle ranging from 45° to 90°), the levers 32 are in engagement with the key 31, influencing his first beard on thrust area 45 figured holes 44 of levers 32, and the bolt 29 is locked against rotary movement by a lead 41 (Fig). Under the force of movement generated by the key 31, the levers 32 are installed in working position, corresponding to the code of the lock, thereby providing the possibility of passing the thrust of the rack 30 through the passage 34 in the shape holes 33 of the levers 32. Thus, in the process of implementing the second phase of the unlocking operation is implemented to transfer the pins 32 from the initial position into the operating position, and this operation is performed by mechanically locked bolt 29 swivel leash 41.

The third phase of the unlocking - phase output key 31 from engagement with the levers 32 - corresponds to the third angular sector of rotation of the key 31 in the direction of unlocking (in this example, this corresponds to the rotation angle ranging from 90° to 180°). In the implementation of this phase, the key 31 is withdrawn from engagement with the levers 32 while maintaining the mechanical lock bolt 29 swivel leash 41, which in this case is found to the right of the thrust section 50 keyholes 49 of the bolt 29, and, at the same time, fixing the set key 31 operating position of levers 32 by the action of the friction element 55. Thus, the third phase is characterized by the fact that the bolt 29 is locked against rotary movement by a lead 41 and levers 32 are in accordance with the key 31 operating position, the fixed friction elements 55.

In the fourth phase of the unlocking of the lock phase unlock and begin to move the bolt 29, the corresponding fourth angular sector of rotation of the key 31 in the direction of unlocking (in this example, this corresponds to the rotation angle in the range from 180° to 315), the levers 32 are in the working position, the fixed friction elements 55 and the bolt 29 is unlocked and is in interaction with swivel leash 41 which move into the housing 27 by force applied to the right thrust area 50 keyholes 49 (Fig). A feature of a specified movement of the bolt 29 is that it is carried out in the absence of direct access to the levers 32 from the side of the key slot 36 through the protective screen 43. Protective screen 43 prevents direct access to the levers 32 from the outside, making it impossible controlled uniquely identifiable accompanying damage to the receiving) change their position with any of the picks.

The fifth phase of the unlocking phase of the end of the movement of the bolt 29 and installation of levers 32 to the initial position corresponds to the fifth angular sector of rotation of the key 31 in the direction of unlocking (in this example, this corresponds to the rotation angle in the range from 315° to 360°). In the implementation of this phase, the bolt 29 is moved into the housing 27 through the force applied by the turning of a lead 41 to the right thrust area 50 figure holes 49 of the bolt 29 and the levers 32 are moved from the operating position to the initial position due to the force applied by the rotary roller 39 from the thrust areas 54 figure of holes 53 of the levers 32.

The end of the fifth phase of unlocking (Fig) corresponds to unlock the lock. In the position corresponding to the unlocked lock, the bolt 29 vdvinul into the housing 27, the rotary lead 41 is in contact with the right thrust area 50 figure holes 49 of the bolt 29 and the levers 32 are in the initial position in contact with the rotary roller 39. In this position, the key 31 is removed from the key slot 36 of the rotary cylinder 35.

For lock insert the key 31 in the key groove 36 of the rotary cylinder 35 and turn the key 31 in a counterclockwise direction.

The first phase lock, the phase of the output rotary roller 39 from engagement with souval the DAMI 32, corresponds to the first angular sector of rotation of the key 31 in the direction of the lock (in this example, this corresponds to the rotation angle in the range from 360° to 315°). In the process of implementing this phase of the rotary roller 39 is withdrawn from engagement with the levers 32, which keep set the initial position by the action of the friction elements 55 and rotating the lead 41 is rotated in the direction of the left thrust area 50 figure holes 49 of the bolt 29, leaving contact with the right thrust area 50.

In the second phase lock phase installation of levers 32 into position and begin to move the bolt 29, the respective second angular sector of rotation of the key toward the lock (in this example, this corresponds to the rotation angle within 360° and 270), the levers 32 are in collaboration with key (with his second beard), and the bolt 29 is in interaction with swivel leash 41 performing his nomination from the housing 27 through the application of force to the left thrust area 50 figure holes 49 of the bolt 29. Under the force of movement generated by the key 31, the levers 32 are installed in working position, corresponding to the code of the lock, thereby providing the possibility of passing the thrust of the rack 30 through the passage 34 in the shape holes 33 of levers 32% in the SSE extension of the bolt 29 of the housing 27.

In the third phase lock - phase movement of the bolt 29, corresponding to the third angular sector of rotation of the key 31 in the direction of the lock (in this example, this corresponds to the rotation angle in the range from 270° to 90°), the levers 32 are in accordance with the key 31 operating position, the fixed friction elements 55 and the bolt 29 is in interaction with swivel leash 41 engaged in its movement from the housing 27 by force applied to the left thrust area 50 figure holes 49 of the bolt 29.

In the fourth phase lock the phase of the beginning of the lock bolt 29 corresponding to the fourth angular sector of rotation of the key 31 in the direction of the lock (in this example, this corresponds to the rotation angle ranging from 90° to 45°), nominated by the bolt 29 is in contact with the rotating lead 41 in the area of their hard area 51, thereby making a mechanical lock and levers 32 are in the working position, the fixed friction elements 55.

The fifth phase lock - phase installation of levers 32 to the initial position corresponds to the fifth angular sector of rotation of the key 31 in the direction of the lock (in this example, this corresponds to the rotation angle ranging from 45° to 0°). In the process of implementing this phase levers 32 move the SJ from the working position to the initial position due to the efforts applied from the side of the rotary roller 39 from the thrust areas 54 figure of holes 53 of levers 32, with extended bolt 29 is locked against rotary movement by a lead 41.

The end of the fifth phase lock corresponds to a closed lock (Fig). At the end of this phase, the bolt 29 is in its extended position and is mechanically locked against rotary movement by a lead 41, which is located opposite the thrust area 51 shaped hole 49 of the bolt 29 and the levers 32 are in the initial position, force established under the influence of the rotary roller 39 on the thrust areas 54 shaped slots 53 of levers 32, thereby making the code lock bolt 29 by blocking the thrust of the rack 30 in their shape holes 33. At the end of this phase, the key 31 is removed from the lock.

Thus, when the vehicle is unlocked considered a lock operation to transfer the pins 32 from the initial position into the operating position, corresponding to the code of the castle, separated in time from surgery to move the bolt 29. In the phase of the transfer levers 32 from the initial position into the operating position during unlocking, it is impossible to move the bolt 29 as a result of its mechanical lock swivel leash 41, and in other phases of unlocking, including phase unlock and move zasova, access to the levers 32 are covered by screen 43, which makes ineffective use any picks for opening the door due to the inability to simultaneously controlled uniquely identifiable with the accompanying impact) changing the position of the levers 32 and bolt 29. All this greatly increases the resistance considered a lock to criminal autopsy.

Reviewed shows that the claimed invention is feasible and ensure the achievement of the technical result consists in increasing the resistance of locks for criminal autopsy carried out by non-destructive methods.
