Abstract

FIELD: locking mechanisms. SUBSTANCE: locking device is intended for preventing unauthorized access into premise, transportation facility, components of security systems, bases of information data. Installed in body of locking device are pairs "pusher-pin". Coding grooves made in them at moment of opening are aligned with slots in locking member. Secrecy of locking device is ensured by free stroke of pins in holes of body due to sliding fit. Due to specific feature, each time after closing of locking device created is multiplicity of combinations in position of pins, and due to absence of forced closing there is no possibility to define moment of opening by touch or ear. Versions of locking device can have mechanical or beam locks, electrical sliding contacts with additional mechanism operating in combination with or instead of lock. Aforesaid embodiment of locking device ensures more secrecy and reliability in functioning. EFFECT: higher efficiency. 3 cl, 4 dwg

Description

 The invention relates to devices excluding unauthorized access to a room, a vehicle, to elements of security systems, information databases.

 A device for locking a door lock containing pairs of a pusher - a pin kinematically connected with a locking element, an allen key and electrical contacts on the pins, the pins being spring-loaded (RU 2046919 C1, 10.27.95).

 A disadvantage of the known device is that the moment of opening of each pair of pusher-pin can be picked up by ear and tactile by reciprocating movements with a master key on one side and the reaction of the spring on the other. In this case, the code pins are alternately displayed with their ends on the plane of movement of the locking element and unlock it. Another disadvantage is the increased wear of the ends of the pushers and pins, as they at the time of opening are affected by the sharp edges of the locking element and the rotary handle.

 A locking device is also known, in the holes of the housing of which pin-pusher pairs are installed, each of which is made in one piece and has a code groove through which the couple is kinematically connected with the locking element (RU 2023122 C1, 11/15/94).

 The known device does not have the necessary degree of secrecy and is not reliable enough in operation.

 The technical result achieved by the implementation of this invention is to increase the secrecy and reliability of the device by eliminating the capture of the opening moment and reducing wear on the ends of the pushers and pins.

 The specified technical result is achieved by the fact that in the locking device containing the key and the housing, in the openings of which are mounted a pair of pins - pushers, each of which is made in one piece and has a code groove, through which the couple is kinematically connected with the locking element, according to According to the invention, the couples are kinematically connected with the electrical contact and are installed with the possibility of free travel, and the key is made with an end face and is equipped with a guide device with an end stop placed with opposites sides of the key pair. The locking element can be made both in the form of mechanical constipation, and in the form of radiation communication between the source and receiver, for example, infrared radiation. Electrical contacts can be made sliding.

 The implementation of the pair of the pin - pusher in the form of a single rod with a code groove and free play without springing does not allow to catch the moment of opening; the connection of the pair with the locking element by means of a code groove also makes the moment of opening implicit; the end stop guarantees the device against spontaneous jamming in any spatial position; the implementation of the locking element in the form of radiation communication significantly reduces wear; making electrical contacts sliding excludes the capture of the opening moment. A new set of features increases the secrecy and reliability of the device.

The invention is illustrated by drawings, where:
in FIG. 1 is a cross-sectional view of a device; in FIG. 2 - the device is locked; in FIG. 3 - in an intermediate state; in FIG. 4 - device with constipation in the form of a beam.

 The locking device comprises a housing 1 with cylindrical holes, in each of which a pair of a pin-pusher 2 with a code groove 3 is installed, a locking element 4 in contact with its slots 5 and grooves 3, an end wrench 6 installed in the guide device 7 provided with an end stop 8 The locking element 4 can be made in the form of radiation communication of the source 9 of infrared radiation and the receiver 10. The electrical contacts 11, mounted on the pins 2, can be made sliding relative to the contacts 12 mounted on rpuse 1.

 The device operates as follows.

 When the guide device 7 is extended (shown by a dashed line), a socket key 6 is inserted into it and all together are pushed all the way into the housing 1. In this case, the pins of the socket key 6 enter the holes of the housing 1 and the pins 2 are moved until the code grooves 3 align with the slots 5 of the lock 4, the latter is unlocked and moved (see FIG. 3) to open, for example, by a spring mechanism (not shown). If the pins 2 are fully extended by an unauthorized attempt to unlock, then the entire pressure of the pins 2 is equalized by the reverse movement of the end stop 8 and the unlocking is repeated. Closing is carried out in the reverse order: the device 7 is pulled forward, the stop 8 aligns the pins 2 at the ends, while the code grooves 3 occupy an intermediate position relative to the slots 5 of the lock 4, the pins 2 of the cylindrical part enter the round holes of the grooves 5, and the lock 4 is fixed ( see Fig. 2).

 In case of an unauthorized attempt to unlock the device by acting on the pins 2, they are displaced and remain in the position in which they were moved. Since the pins 2 are installed with the possibility of free play on the slide fit, the opening moment, i.e. the position at which the code grooves 3 with their edges coincide with the planes of movement of the constipation 4, to catch by ear and tactile is very difficult. If, nevertheless, one of the pins was set at the time of opening, then when manipulating the other pins by means of a picklock and stop 8, the exposed pin will be shifted and the secrecy of the device will be restored to its original level.

 In the same way, the device is unlocked-locked by means of the sliding contacts 11, 12, but the electrical signal is supplied to the auxiliary power mechanism. Contacts 11, 12 may be the only secrets or used along with constipation 4 to increase privacy.

 When used as a locking element of a light beam (see Fig. 4), the latter passes through the grooves 3 and reaches the radiation receivers 10, forming a signal for opening. When moving the pins, the beam does not pass, the device does not unlock.
