SYSTEM OF CYLINDER LOCKS AND KEYS Russian patent published in 2020 - IPC E05B19/00 

FIELD: locks.

SUBSTANCE: invention relates to a system of cylinder locks and switches. System comprises cylinder locks (100, 300, 500, 700, 900, 1300, 1500, 1700) and keys (200, 400, 600, 800, 1000, 1100, 1400, 1600). Each lock comprises housing (102, 1502, 1702), having cylindrical groove, and cylinder (104, 904, 1504, 1704), installed in housing with possibility of rotation around axis of rotation and having front end (106, 1506, 1706) and key slot (114, 1514). Each key has head (201, 1101) and blade (202, 1102), made with possibility of introduction, by means of translational motion, in the key slot of the corresponding locks to the full insertion and turning position from the introduced position around the said axis. Cylinders and keys are provided with interacting retaining surfaces to define the position of complete insertion of keys into key slots. First and second locking surfaces are configured such that when the correct key is fully inserted into the key slot of the corresponding lock, at least one first stop surface is in contact with corresponding second locking surface. At least two first locking surfaces (212a, 212b; 412a, 412b; 612a, 612b; 812a, 812b; 1012a, 1012b; 1112a, 1112b) of each key are located one next to each other, and at least two second locking surfaces (112A, 112B; 312A, 312B; 512A, 512B; 712A, 712B; 912A, 912B; 1512A, 1512B; 1712A, 1712B) of each lock are located one next to the other in the plane of inlet (116) ) of key slot (114, 1514) or nearby it. Invention also relates to combination of cylinder lock and key, to key, to key blank and to cylinder lock.

EFFECT: disclosed is a system of cylinder locks and switches.
