LOCK Russian patent published in 2023 - IPC E05B25/00 E05B17/22 

FIELD: locks.

SUBSTANCE: lock refers to hardware installed in the entrance doors of hotel rooms, and is designed to turn off electrical consumers left on when the guest leaves the room. The lock contains a body with a guide for the key, an electrical contact installed in the door jamb that interacts with a bolt placed in the guide groove and having a bolt plate equipped with a comb and a locking post, a means for locking the bolt, including a set of spring-loaded levers with code protrusions formed by notches for interaction with the locking post, a second bolt placed in its guide groove and a double-bit key. Additional guides are installed on the inside of the housing, coaxial with the guide grooves. The crossbars are made to interact with each other by means of a strip fixed to the body in the middle, with the possibility of rotation, with grooves at the ends in which screws, fixed in the crossbars, are located. The code protrusions in the grooves of the levers, located closer to the crossbar, correspond to the secrets on the bits of the key inserted from the corridor when it is turned completely. The code protrusions in the grooves of the levers, located further from the bolt, correspond to the secrets on the bits of the key, inserted from the number when it is turned completely. The guide for the key is equidistant from the extreme notches of the levers.

EFFECT: it is possible for police and emergency medical workers to enter in case of emergency, together with the hotel administrator, who will be able to get into the room by opening it from the corridor with a spare key.
