Unit for Duplicating Recesses of a Cylindrical Key

摘要

It is the object of this invention to provide a unit for duplicating recesses of a key with a cylindrical shank. A unit 1 for duplicating recesses of a key 2 with a cylindrical shank in a duplicating machine, where the key comprises a gripping part 3 and a cylindrical operational shank 4 on the surface of which encoding recesses 5 are made that cooperate with elements to unlock a lock mechanism, such as bolts, and on the outer surface of which, radially to the axis of the key, an abutment 6 is positioned that secures the position of the key 2 in the lock mechanism and transfers driving force from the key 2 to the lock mechanism, where the duplicating machine 7 is provided with two receptacles 8, where in the first receptacle 8 a master key 2 to be duplicated is inserted, and in the other receptacle 8 a blank key 2 is inserted, and the receptacles 8 have a flat key shape in cross-section. The unit 1 has a body 9 with an internal receptacle 10 with a recess 11 for an abutment 6 of the shank 4 of the key 2, where a cylindrical key 2 is inserted, and the unit 1 is provided with elements for securing in a duplicating machine 7.
