Abstract:
A combination lock comprising:a cable (10) a retaining member (11) attached to one end of said cable (10), and including a support rod (112), multiple separate first locking lugs (114) formed on the outside of said support rod (112), multiple separate second locking lugs (115) formed on the opposite side of said support rod (112), each of said second locking lugs (115) having a dimension different from that of said respective first locking lug (114); multiple tumblers (20) corresponding to the pairs of first and second locking lugs (114, 115) each rotatably mounted on said support rod (112), and each including a number wheel (21), a follower (22) detachably secured in said number wheel (21) to rotate therewith, a push disk (23) slidably secured in said number wheel (21) and abutting said follower (22), a torsion spring (24) attached to said push disk (23) and secured in said number wheel (21), said follower (22) defining a first locking recess (226) aligning with and having a dimension corresponding to said first locking lugs (114) and a second locking recess (227) aligning with and having a dimension corresponding to said second locking lugs (115); wherein said push disk (23) defines a first mating recess (233) aligning with and having a dimension corresponding to said first locking lugs (114), and a second mating recess (234) aligning with and having a dimension corresponding to said second locking lugs (115); a number reset device (30) mounted on said support rod (112) and abutting one of said tumblers (20) to detach said follower (22) from said number wheel (21) such that said number wheel (21) can be rotated relative to said follower (22); a locking member (12) mounted on the other end of said cable (10), and including a locking rod (122) detachably secured in said support rod (112) by said tumblers (20); and a compression spring (117) mounted on said support rod (112), and located between one of said tumblers (20) and said retaining member (11); whereby the corresponding relationship of the first and second locking lugs (114, 115) and the first and second recesses (226, 227) and the first and second mating recesses assure that the lock will be assembled with a correct assembled angle.
