Abstract:
1. A lock driving mechanism for use in a lock having a cylindrical housing having a hollow receiving hole with an axial direction, the lock driving mechanism held rotatably in the hollow receiving hole, and a fastening member mounted to the cylindrical housing to hold the lock driving mechanism in the hollow receiving hole, said lock driving mechanism comprising: an inner driving member having an inner panel, said inner panel including an inner surface, an outer surface, a center, an imaginary inner concentric circle and an imaginary outer concentric circle being provided on said outer surface of said inner panel; a lock core driver having at least one inner arm extending from said inner surface of said inner panel; an inner driver having two inner stop portions formed on and protruding in the axial direction from said outer surface of said inner panel, said two inner stop portions being located on a track of said imaginary inner concentric circle of said outer surface of said inner panel; an outer driver having two outer stop portions formed on and protruding in the axial direction from said outer surface of said inner panel, said two outer stop portions being located on a track of said imaginary outer concentric circle of said outer surface of said inner panel, wherein said inner panel, said lock core driver, said inner driver and said outer driver are monolithic, a lower semicircular track is between said inner driver and said outer driver, and an upper semicircular track is located outside of said inner driver; an outer driving member coupled to said inner driving member and having an outer panel, said outer panel including an inner surface, an outer surface and a center; an inner bump formed on and protruding in the axial direction from said inner surface of said outer panel; an outer bump formed on and protruding in the axial direction from said inner surface of said outer panel; and a latch driver having at least one outer arm extending from said outer surface of said outer panel; wherein said inner bump on said inner surface of said outer panel is located on a rotating track corresponding to said imaginary inner concentric circle of said outer surface of said inner panel when said outer panel is coupled to said inner panel; wherein said outer bump on said inner surface of said inner panel is located on a rotating track corresponding to said imaginary outer concentric circle of said outer surface of said inner, panel when said outer panel is coupled to said inner panel; wherein said inner bump and said outer bump are located between said outer surface of said inner panel and said inner surface of said outer panel, there is a space formed between said outer surface of said inner panel and said inner surface of said outer panel, said inner bump and said outer bump are capable of being moved within said space; and wherein said inner stop portions of said inner driver and said outer stop portions of said outer driver are adapted to rotate said inner bump and outer bump respectively; wherein said inner driving member is circular disk shaped with said inner driver and said outer driver protruding in the axial direction.
