LOCK CYLINDER MECHANISM, KEY FOR LOCK CYLINDER MECHANISM AND METHOD FOR LOCK CYLINDER MECHANISM CODING

摘要

FIELD: construction. ^ SUBSTANCE: inventions are attributed to locking devices. Contains body where cylinder with channel slot for key is embedded which cylinder is able to rotate around its axis. In the body and in the cylinder coaxial holes are made and in these holes spring-loaded locking pins are located which are able to trig the cylinder against its turn and to release the cylinder in known manner and flat key with chamfered code projections with possibility to fix key position in channel slot for key relative to cylinder axis. One of the key channel slot walls coincides with diameter plane of cylinder. Stepped indents are made in spring-loaded locking pins located on the way of channel slot for key. Hole is made along cylinder axis and stepped indents are also made in spring-loaded locking pins located on the way of this hole passing. Spring is embedded in this hole. This spring interacts with spring-loaded locking pins. Lengths of spring-loaded pins are equal to cylinder diameter. Key blade width is less than height of channel slot for key, and chamfered projections of key are made either on both side of key blade or on one of its sides. ^ EFFECT: raise of lock cylinder mechanism unbreakability. ^ 7 cl, 5 dwg
