DOOR ELECTROMECHANICAL LATCH FOR LOCKING DEVICE Russian patent published in 2019 - IPC E05C1/00 

FIELD: hardware.

SUBSTANCE: door latch on locking device comprises housing 1 with installed on it handle 3. In housing 1 there is motor-reducer 5, kinematically connected to it and connected to handle rotation mechanism with contacts for registration of handle rotation, microcontroller connected to motor-reducer 5 with possibility of its switching on and off, and radio signal reception and transmission device connected to microcontroller. Handle 3 is made with central opening for locking device and with peripheral arc-shaped groove. Rotation mechanism includes gear wheel 6 installed coaxially with handle 3, contact ring 11 and cover 15 connected to it with possibility of combined rotation with two spring contacts 14 connected to microcontroller. Gear wheel 6 is connected with motor-reducer 5 and has ledge located in arc-shaped groove of handle 3 with possibility of movement in it when handle 3 turns through 180° and with possibility of interaction with end faces of groove and turn of handle 3 when gear wheel 6 is rotated by motor-reducer 5. Contact ring 11 is made with a conducting inner ring and external sectors, which are connected to microcontroller and with which corresponding spring contacts 14, located on cover 15, wherein all external sectors have different resistance between each sector and inner ring. Latch is provided with a handle position sensor connected to the microcontroller.

EFFECT: door fittings are designed for opening or closing of door locking devices.
