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

FIELD: locks.

SUBSTANCE: present invention relates to locks installed in the entrance doors of hotel rooms, designed to turn off electrical consumers when leaving 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 a guide groove and having a bolt plate equipped with a comb, a locking post and a groove for sliding along a cylindrical guide, 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, and a double-bit key. An additional cylindrical guide is introduced into the body, placed in the groove of the crossbar plate, and an axis on which a crossbar, made in the form of a truncated gear, is mounted with the possibility of rotation, interacting with the side surface of the crossbar plate equipped with teeth. 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 to operate the control mechanism of the second bolt from the corridor in order to open the lock.
