    摘要: A cycle lock having at least one plurality of disc-like tumblers loosely mounted on a shaft parallel with the axis of rotation of the key rotated lock cylinder. Each tumbler has a two spaced lobes which, in the neutral state of the tumbler, contact the arcuate surface of the cylinder but one of the lobes may drop into the key slot in the cylinder if not occupied by a high segment on the key. A key is initially inserted into the lock at a special location at which all tumblers are in their neutral state, and the rotation of the key to its normal position of insertion and removal will set the lock tumblers according to the key coding. In one embodiment particularly useful for hotels, etc., two sets of tumblers are employed: one set for transient or guest keys, a second set for service personnel keys, and a third key, a grand master key, operates the second tumbler set and can reset both sets of tumblers for accepting new keys with different codings thereon.
