The technical problem is to increase the resistance of locking and unlocking a lock to criminal action by eliminating the possibility of opening the lock with skeleton keys. Once a key code has been registered, when the key is turned the key code is stored without the possibility of changing any element of the code, and blocking of a device for comparing the stored key code with a lock code is switched off, and then, upon further turning of the key, the stored key code is compared with the lock code and, when the codes correspond to one another, movement is transmitted to a lock hasp drive. The device includes a device for storing the key code without the possibility of changing any element of the code, said device constituting a set of discs mounted between cylinder pins and lock pins, and the device for comparing the stored key code with the lock code, said device comprising a spring-mounted code-correspondence catch with a projection, which catch is mounted in a housing opening, and having a direct connection to openings for the lock pins, and the lock pins with annular code grooves, the position of which corresponds to the lock code.

Description

METHOD FOR LOCKING AND UNLOCKING THE LOCK AND LOCK FOR ITS

IMPLEMENTATION

Technical field

The technical solution relates to locking methods and devices with increased secrecy, in particular, to locking mechanisms of cylinder locks, which can be used in various designs of locks for doors, safes, cars, etc.

State of the art

A known method of encoding a cylinder mechanism of the lock (RF Patent N ^o 2223374 published July 27, 2004), providing increased cryptographic protection of locking devices. In the method of encoding a cylinder lock mechanism including a housing, a first rotary drum, pushers, spring-loaded pins and a push key with protrusions, namely, that the first rotary drum is placed in the housing, axial holes are made in the first rotary drum and pushers are placed in them which are in contact with spring-loaded pins, the end of one of which is inserted into the first rotary drum with the possibility of contact with the protrusion of the key when it is inserted into the lock, the essence of the invention It is that a second rotary drum is placed in the housing in contact with the first rotary drum, axial holes are made in the second rotary drum and spring-loaded pins are placed in them, a timer is fastened to the housing, its axis is fastened with a winding spring to the axis of the second rotary drum with the possibility of simultaneous rotation of the rotary drums at an angle smaller than the angle of the opening of the lock when trying to open the lock with a key by entering the key incorrectly and then braking the first rotary drum so its rotation correctly entered into the lock key for a predetermined time, after which the first rotary drum is released.

The specified method is implemented in analogue (RF Patent Na 2223374 published July 27, 2004). The cylinder lock mechanism comprises a housing in which the first rotary drum is placed, axial holes are made in the first rotary drum and push pins are placed in them, spring-loaded pins in contact with them, a pressure key having at least one protrusion, a second rotary drum, a timer and a locking protrusion , spring-loaded pins, at least one spring-loaded pin of the second drum enters the axial hole of the first rotary drum and acts as a delay, the timer is fixed to the housing, the clockwork axis timer springs connected to the axis of the second rotary drum.

The disadvantage of this method of encoding a cylinder lock mechanism and a known cylinder lock mechanism is the complexity of manufacturing and implementation of the proposed technical solutions.

The closest in technical essence to the proposed technical solution of the method is the method of locking and unlocking the lock, implemented in English type locks with a radially pin cylindrical privacy mechanism (USSR Author's Certificate 520794, class E 05 B 35/04, 1977). Locking includes the processes of installing the key in the keyhole, fixing the key code and turning on the lock bolt drive, and installing the bolt in the locking position by turning the key and removing the key from the keyhole after locking. Unlocking is carried out similarly to locking when the key is turned in the opposite direction.

Closest to the proposed castle is the castle (USSR Copyright Certificate 520794, class E 05 B 35/04, 1977). The lock contains a housing in which a cylinder mechanism is located, consisting of a cylinder with a slot for the key and the holes in which the pins are installed cylinder, and spring-loaded lock pins installed in the lock housing, and lock bolt drive.

A disadvantage of the known method of locking and unlocking the lock and the known cylinder mechanism of the lock is its low forensic resistance when opening the locking device with master keys, due to the fairly free access through the keyhole to the pins separately and the possibility of determining the code position of the pin by registering the response to the action of a separate pin.

Summary of the invention ⁴

The technical problem to be solved for the proposed method and device is to increase the forensic resistance of locking and unlocking the lock by eliminating the possibility of opening the lock with master keys.

The technical result in the method of locking and unlocking the lock by installing the key in the keyhole, fixing the key code, turning on the lock bolt drive and installing the bolt in the locking or unlocking position by turning the key depending on its direction of movement, and removing the key from the keyhole after locking or unlocking the lock is achieved by the fact that after fixing the key code when turning the key, the key code is stored without the possibility of changing any code element, the comparison lock is disabled th code key code lock, then upon further rotation of the key is compared with the stored key code lock code, and the coincidence of the codes transmit the motion to the drive bolt lock.

The technical result in the lock containing the housing, in which the cylinder mechanism is installed, consisting of a cylinder with a slot for the key and holes in which the cylinder pins are installed, spring-loaded lock pins installed in the housing holes, and the lock bolt drive are achieved by entering key code device without the possibility of changing any code element, which is a set of washers installed between the cylinder pins and the lock pins, and a device for comparing a stored key code with a lock code, including a spring-loaded lock key for matching codes with a protrusion installed in a housing hole having a direct connection with holes for lock pins, and lock pins with ring code grooves, the positions of which correspond to the lock code, on the code matching lock there are grooves located when the device for comparing the stored key code with the code is turned off the lock in accordance with the location of the lock pins and do not interfere with the free movement of the lock pins when installing the key in the keyhole, between the grooves there is a spike of the code matching lock, the shape of which in cross section coincides with the shape of the ring code groove on the lock pins, the protrusion of the code matching lock is included in a curly annular slot located at the rear of the cylinder after the pin holes, a curly annular slot on the cylinder has a protrusion and latches, which are made in this form so that it is possible to turn off the device for comparing the memorized copy of the key with the lock code when the key is installed with locks, to limit the rotation of the cylinder if the key code does not match the lock code and, if the key code matches the lock code, activate the bolt drive to unlock or lock the lock depending on the direction of movement of the key.

The key code is an encrypted combination of code elements of the security mechanism of the lock. The key code is determined by the set of sizes of the protrusions (barbs) relative to the base surface of the key. Lock code - an encrypted combination of code elements of the security mechanism of the lock, providing control of the bolt (deadbolt) drive. The code elements of the lock have a certain (encrypted, secret) height (depth, tilt angle, etc.) from the key base. Before the key is installed and when the inserted key is in the zero position, the device is blocked comparing the stored key code with the lock code, this means that the cylinder pins and lock pins can move freely without any reaction from the side of the device for comparing the stored key code with the lock code. When the key is turned, the lock is disabled, but there is no possibility of affecting the lock pins. When the lock is disabled, the device can compare the stored key code with the lock code.

When installing the key in the keyhole, the key code is fixed, i.e. the cylinder pins take the position corresponding to the key code and, therefore, the associated code elements of the lock occupy the corresponding positions. When you turn the key, this code combination of the code elements of the lock is remembered. The lock code element is a pin on which there are code grooves located at a certain distance from the base surface of the lock pin. If the lock code corresponds to the key code, then all code grooves are installed in one line. A device for comparing a stored key code with a lock code checks to see if all code holes are on the same line. If the lock codes coincide with the key code, the cylinder makes a complete revolution. A tongue directly connected to the lock cylinder is often used as a crossbar drive. When the tongue is turned a full turn, the bolt (deadbolt) is shifted and this ensures locking or unlocking of the lock, depending on the direction of movement of the key.

DESCRIPTION OF PREFERRED EMBODIMENTS

The lock (device) for implementing the locking and unlocking method shown in FIG. 1, comprises a housing 1, in which a cylinder mechanism is installed, consisting of a cylinder 2 with a slot for a key 3 and holes 4 of the housing 1 and cylinder 2, into which the pins 5 are installed cylinder 2, spring 6 lock pins 7, and lock bolt drive 8, a key code memory device without the possibility of changing any code element, which is a set of washers 9 installed between cylinder 2 pins 5 and spring lock pins 7, and a memory code comparison device a key with a lock code, including a spring-loaded lock 10, a latch 1 1 for matching codes with a protrusion 12, installed in the hole 13 of the housing 1, and lock pins 7 with ring code grooves 14, the position of which corresponds to the lock code There are grooves on the lock 1 1 of the coincidence codes, located when the device for comparing the stored key code with the key code is turned off in accordance with the location of the lock pins 5 and do not interfere with the free movement of the lock pins 7 when the key 3 is inserted into the keyhole, there is a spike 15 between the grooves latch 1 1 matching codes, the shape of which in cross section coincides with the shape of the annular code grooves 14, the protrusion 12 of the latch 1 1 matching codes is included in a curly ring slot 16 located in the rear part cylinder after the pin holes, the curved annular slot 16 on the cylinder 2 has a protrusion 17 and latches 18, which are made so that it is possible by the protrusion 12 of the latch 1 1 matching codes to disable the device for comparing the stored key code with the lock code when the key is removed 3 or installation of the key 3, the clamps 18 to limit the rotation of the cylinder 2 when the key code 3 does not match the lock code, one of the clamps 18 will limit the rotation of the key when unlocking, and the second - when locking the lock, and if the key code 3 with the lock code How to actuate the crossbar drive 8 to unlock or lock the lock, depending on the direction of movement of the key 3.

Consider the implementation of the proposed method of locking and unlocking the lock and the operation of the lock using the device depicted in figure 1. When using the specified method in locks An English-type device operates as follows. When installing the key 3 in the slot of the cylinder 2 under the action of the protrusions of the key 3, the pins of the cylinder 5 are installed in accordance with the key code 3 and the key code is fixed. The pins of the cylinder 5 using the key code memory device, consisting of a set of washers 9, push the spring-loaded pins 7 installed in the lock case. In this case, in accordance with the key code, part of the washers will remain in cylinder 2, and the rest will go into the lock case. When turning the key 3, this distribution of the washers 9 is saved without the possibility of changing it, and the code of the key 3 is stored without the possibility of changing the code of any element. In accordance with this, the code grooves 14 of the lock pins 7 will take the position in accordance with the key code 3. If the lock code corresponds to the key code, then the code grooves 14 are lined up. With further rotation of the cylinder 2, the protrusion 17 of the annular slot 16 of the cylinder 2 releases the protrusion 12 of the latch 1 of the code coincidence and makes it possible to move the latch 1 1 of the code coincidence under the action of the spring 10. The need to block the operation of the device for comparing the stored key code with the lock code is so that if there is no key, when there is access to the pins 5 of cylinder 2, exclude the possibility of determining the code of any of the elements by registering the response to the impact on a separate pin 5 of cylinder 2. If the key code 3 is If the lock code is used, then the code grooves 14 of the lock pins 7 are aligned and provide unimpeded movement of the spikes 15 of the latch 1 1 for matching the code under the action of the spring 10, while the protrusion 12 of the latch 1 1 for matching the codes goes to the section of the annular slot of the cylinder 16, on which rotation of the cylinder 2 by a full revolution, while the crossbar drive 8 makes a full revolution and provides locking or unlocking of the lock depending on the direction of movement of the key. If the key code 3 does not match the lock code, then part of the spikes 15 abut against the body of at least one of the lock pins 7 and thereby the movement of the lock 1 1 the coincidence of the codes under the action of the spring 10 is not possible and the position of the protrusion 12 of the latch 1 1 matching codes remains unchanged. When the cylinder is turned, the protrusion 12 of the latch 1 1 of the coincidence of codes reaches the limiters 18 of the annular slot 16 of the cylinder 2 and further rotation of the cylinder 2 is impossible. Therefore, if the lock codes and the key do not match, the lock cannot be opened.

The technical result is an increase in the forensic resistance of the method of locking and unlocking the lock by eliminating the possibility of opening the locks with master keys, in comparison with the prototype is provided as follows.

In the prototype, when the key is inserted into the keyhole, the cylinder pins are moved due to the key protrusions, which drive the spring-loaded lock pins. In this case, the dividing line between the cylinders occupies a well-defined position. If the dividing line of the pins coincides with the dividing line of the cylinder and the casing, then the cylinder is allowed to rotate with a key relative to the lock casing. Further, when turning, the movement is transmitted to the lock bolt drive. If the cylinder dividing line does not coincide with the dividing line between the cylinder and the housing, then such a rotation of the cylinder relative to the housing is not possible.

Thus, to open the lock, it is necessary to combine the interface between the pins with the interface between the cylinder and the body. In the absence of a key in the keyhole, the prototype provides fairly free access to each of the pins, acting and checking the reaction to this effect for each pin, it is easy to determine the position when the dividing line between the pins coincides with the dividing line between the cylinder and the body. This position is fixed for each of the pins, which explains the low cryptographic resistance to opening the lock with the help of master keys.

In the proposed method of locking and unlocking the lock and the lock for its implementation, the technical result (increase forensic the durability of the method of locking and unlocking the lock by eliminating the possibility of opening the locks with master keys) is achieved by comparing the lock code with the stored key code. This eliminates the possibility of exposure to a single pin and determining the response to this effect. In the absence of a key in the keyhole, there is access to the cylinder pins, but due to the fact that in this case the device for comparing the stored key code with the lock code is disabled, it is not possible to determine the response of the system to the effect of a separate pin. In addition, full code combinations of the lock code and the stored key code are checked. Mismatch of at least one position when comparing codes makes it impossible to unlock or lock the lock device.
