Abstract

The invention provides an electronic lock, in which body 14 there is mounted a bar 1, a bar shifting mechanism including riegel 2 (bolt), a control lever 3 and a blocking mechanism. The latter is made in form of an electromechanical catch which moving plate 11 is coupled to a limiter 8 blocking the bar shifting mechanism. In the present aspect of the electronic lock a power consumption is reduced significantly. <MATH>

Description

 The invention relates to locking devices, in particular to electronic locks for residential and office space, safes and vehicles.

 Known locks with electronic or mechanical keys, in which the deadbolt interacts with the control element through the use of an electromagnet, and its coil is electrically connected to a resolving means (ed. St. N 1694066, class E 05 B 47/00, 1990).

 The lack of locks of this type is the presence of a power connection between the bolt and the control element, which is carried out through a sufficiently powerful electromagnet. The high power consumption of the lock makes it possible to work only from the network or from an energy-intensive battery.

 Also known is the electronic lock adopted for the prototype, in which the electromagnet is used only to unlock the deadbolt and is turned on through the processor by a signal from the electronic key. However, even a small electromagnet consumes noticeable power and in the case of using the built-in power supply, it is necessary to periodically recharge or replace it, which affects the performance of the lock.

 The purpose of the invention is a multiple reduction in the power consumed by the electronic lock and an increase in its operational characteristics.

 This goal is achieved by the fact that in the known electronic lock containing a deadbolt, a mechanism for moving and locking the deadbolt with control levers fixed to a common shaft, equipped with a handle disconnect device and a permitting device, the handle disconnect device is made in the form of an electro-adhesive capture containing separated by a dielectric electrically conductive plates, one of which is fixed motionless, and the second is mounted with the possibility of movement and connected with the limiter, inter acting with a cam mounted on the shaft of the handles, moreover, the plates are electrically connected to the power source through a resolution device.

 As an example, there is a constructive solution of the lock in the mortise version. By a similar principle, the lock can be made in the overhead version.

 In FIG. 1 shows a lock with an extended deadbolt and disconnected control handles, a longitudinal section; in FIG. 2 same, cross section; in FIG. 3, section AA in FIG. 2; in FIG. 4 a section BB in FIG. 3; in FIG. 5 lock with retracted deadbolt and control levers turned on, cross section; in FIG. 6 a section BB in FIG. 5; in FIG. 7 section GG in FIG. 6; in FIG. 8 node I in FIG. 2.

 The electronic lock contains a housing 1, inside which a bolt 2 is mounted with the possibility of longitudinal movement. A pin 3 is fixed in the deadbolt, which interacts with the mechanism for moving and locking the bolt, which includes a leash 4 made with a slot 5. A sleeve 6 is installed in the bore of the leash 4, having a slot 7. In the slots 5 and 7, a plate retainer is installed 8. On the housing 1 is fixed a deadlock blocking board 9 made with a slot 10. A shaft 11 passes through the sleeve 6, on which the external control handle 12 is fixed, the internal a handle 13 and a cam 14 provided with a protrusion 15. A spring 17 is mounted on the shaft 11 under the casing 16. An electro-adhesive gripper 18 is installed in the housing 1, which includes electrically conductive plates 19 and 20 separated by a dielectric 21. The plate 19 is fixed to the housing 1 fixedly and the plate 20 is mounted with the possibility of longitudinal movement. A pin 22 and a lever 23 are fixed on the plate 20. A limiter 24 is mounted on the pin 22 for interacting with the cam 14. The lever 23 interacts with the microswitch 25 fixed in the housing 1. The spring 26 interacts with the pin 22. The plates 19 and 20 are electrically connected with a resolving means, made, for example, in the form of a processor turned on by an electronic key.

 The lock is powered from a small-sized source of energy, for example, from a Krona battery. The electrical system of the lock includes a converter, from which increased voltage is supplied to the capture plate. When the electronic lock is in a de-energized state, the electro-adhesive gripping plates 19 and 20 are disconnected, the handles 12 and 13 are disconnected from the bolt moving mechanism and rotate freely. In this case, the shaft 11 is shifted towards the inner handle 13, and the protrusion 15 of the cam 14 is disengaged from the leash 4, which, together with the bolt 2, is locked by a latch 8, which enters the slot 10 of the plate 9. The control handles are held in the off position due to the interaction of the end surface of the protrusion 15 of the cam 14 with the end surface of the leash 4, and also due to the interaction of the limiter 24 with the end surface of the cam 14.

After every 360 ^of rotation of the control handle 15, the cam protrusion 14 of its cylindrical surface comes into contact with the stopper 24, it moves together with the movable plate 20 and the outputs of cam 14. Simultaneously, the lever end 23 pushes on the plunger of the microswitch 25. In this case, the control handle continue to be kept in an off state, since in this angular position of the cam 14, its protrusion 15 does not coincide with the slot 5 in the lead 4. After the resolving device is triggered, for example, by a signal from an electronic key, multi-polar voltage is applied to the electroadhesive gripping plates through the micro switch 25. Voltage can only be applied when the microswitch rod is pressed, i.e., with a certain angular position of the cam 14 and the control levers. After voltage is applied between the plates, an electro-adhesive bond occurs, the movable plate 20 is fixed relative to the fixed plate 19, as a result of which the stopper 24 remains in the position shown from FIG. 5.

 With further rotation of the handles, the protrusion 15 of the cam 14 enters the slot 5 of the leash 4 and, under the action of the spring 17, the shaft 11 moves towards the outer handle 12, unlocking the deadbolt 2. The control handles are connected to the mechanism for moving and locking the deadbolt. Their subsequent rotation leads to the extension or retraction of the bolt 2.

 To disconnect the handles, it is necessary, by the signal of the electronic key, to remove the voltage from the electro-adhesive grip and press the external handle 12 or pull out the internal handle 13. The protrusion 15 of the cam 14 leaves the slot 5 of the lead 4 and the limiter 24 moves and falls under the end of the cam 14, under the influence of the spring 26, locking handles in the disconnected position.

 The advantage of the lock is its small thickness, which allows the lock to be made both in mortise and in overhead versions.

 High technical and operational characteristics of the castle, the simplicity of its design allow us to conclude that the castle is industrially applicable and can be manufactured in mass production.
