LOCK CYLINDER MECHANISM WITH KEY Russian patent published in 1995 - IPC

FIELD: locking arrangements. SUBSTANCE: lock cylinder mechanism with key has a housing with central and transverse openings, locking elements, springs, core with a longitudinal duct and transverse openings, pushers, bearing balls and a key. The pushers and locking elements are made as balls having a diameter equal to that of the bearing balls. Besides, a gasket is placed even in one of the transverse openings of the core between the pusher and bearing ball. In its initial part the key has at least one bevel, and its thickness equals the height of the longitudinal duct and equals the radius of the balls. Through recesses with bevels are made on the key working part. To simplify the design, the springs can be made as plates with lugs according to the number of locking elements. To enhance the security, the duct in the core can be made as a plane slot, and the key as a plate. To decrease the longitudinal dimensions, the longitudinal duct in the core can be made as an annular one, and the key can be made as a tubular one. EFFECT: enhanced reliability. 5 cl, 8 dwg
