LOCK MECHANISM Russian patent published in 1994 - IPC

FIELD: construction. SUBSTANCE: provision is made for a housing with mechanism base and keyhole secured on the body, carrier controlling the train and key with a code hole linked with it that successively bear against the base. The mechanism has at least a pair of pockets formed by coaxial holes of the carrier and base with pairs of spring-loaded pins positioned in each of them. On the side of the key the pins have a key-receiving part, one of them together with this part has a length equal to the sum of the key and carrier thicknesses. The key hole is in fair with the mechanism pocket carrying the larger pin bearing against the key. The key and keyhole have the shape of an open cylindrical profile. The carrier and mechanism base are made in the form of a cylindrical head with the keyhole coaxially extending in it and bush and placed one in the other. The mechanism pockets and code keyhole extend radially. The carrier is provided with an external dog extending coaxially with it for coupling with the train. EFFECT: enhanced reliability. 6 dwg
