LOCK (VERSIONS) Russian patent published in 2015 - IPC E05B29/00 

FIELD: construction.

SUBSTANCE: invention relates to the mechanical locks, key secret blocks of the cylindrical type. Lock according to the first option comprises a case of secret unit with longitudinal locking groove in its inner cavity, rotor with longitudinal groove joined with each other mounted in the case with possibility of rotation, hole for key and locking cavity with fixing element arranged in the last mentioned. Fixing element is designed with possibility of interaction with longitudinal locking groove of the case. Longitudinal groove with pushers installed in it similar by shape and length with projections on its opposite sides, is located between the hole for the key and locking cavity. Fixing element is designed in the form of comb coupled with the base. Comb of the fixing element is arranged in the locking channel of the rotor, and on its base the elements, interacting with projections on the facing sides of pushers in case of interaction of other protrusions of pushers on the opposite sides to them and operating surface of the key mounted in the hole, are made. Protrusions, interacting with grooves on sides of pushers facing to the fixing element in case of interaction of protrusions of pushers on their opposing sides with working surface of the key, are made on the base of fixing element according to the second option of the invention. Longitudinal groove coupled with the key with pusher and locking surface with fixing device, the comb of which has the possibility of interaction with the additional locking recess in the case, can be made in rotor on the other side from the hole for the key.

EFFECT: simplification of assembly by eliminating the use of table of code combinations from its process.
