Abstract:
1. A cylinder lock, including: a housing having a cylindrical bore therein; a rotor assembly rotatably mounted within said bore; a plurality of locking bars arranged on said rotor assembly, each locking bar including a locking bar pin directed radially inward towards the axis of said rotor assembly, wherein each locking bar is displaceable on the rotor assembly in a direction substantially parallel with said axis, and each locking bar is displaceable in a radial direction with respect to said axis; and a combination post arranged along said axis, said combination post having a plurality of combination holes formed thereon; wherein each of said locking bars is adapted to be displaced by a coded key, in said substantially parallel direction, to a position in which the locking bar pin of each said locking bars is directed towards a respective combination hole; said rotor assembly is adapted to be rotated by said key to an unlocking position, wherein at various rotational positions each said locking bar is radially displaced towards said axis, thereby engaging each said locking bar pin with a respective combination hole, so as to permit rotation of said rotor assembly within said bore.
