    摘要： A cylinder lock is provided that key-change is possible without taking out auxiliary tumblers to the outside, the number of keys subjected to the key-change can be increased correspondingly to the number of auxiliary tumblers, and also, each key can be set, limitlessly in the number of times, as not-usable/usable so that even after use of a master key, other adaptable keys are usable.A cylinder lock which comprises auxiliary tumblers interposed between the upper tumblers and the lower tumblers of spontaneously selected pairs of upper tumblers and lower tumblers, so that the auxiliary tumblers can be moved aside from between the upper and the lower tumblers, thereby enabling a change of keys for locking and unlocking the cylinder lock,wherein there are formed a plurality of elongated accommodation holes longitudinally of the outer peripheral surface of the inner cylinder, and there is formed a groove connecting with the plural accommodation holes, a set/reset member is freely slidably arranged in the groove, the set/reset member being provided at the edge with crests and roots formed alternately continuously to each other, so that there are structured to enable: a set state that an adaptable key is inserted into the keyway of the inner cylinder, function of serration and surface figuration of the key moves the auxiliary tumblers interposed between the upper tumblers and the lower tumblers into the upper tumbler bores, the inner cylinder is turned with the auxiliary tumblers being positioned in the upper tumbler bores, the auxiliary tumblers are brought into a situation of hitting and contacting with crests of the set/reset member, the set/reset member in this situation is pushed through an outside operation to move the auxiliary tumblers contacting with the crests to a position of facing the roots, the auxiliary tumblers are accommodated into the accommodation holes thanks to an urging force of a spring for the upper tumblers, so that when pushing the set/reset member is released, the auxiliary tumblers are pushed longitudinally of the elongated accommodation holes and held prevented from moving back to the upper tumbler bores; and a reset state that an adaptable key is, in the set state, inserted into the keyway of the inner cylinder, the inner cylinder is turned to cause the accommodation holes to face the upper tumbler bores, thereafter, the set/reset member is pushed further largely than the amount of pushing the set/reset member in the case of making the set state, thereby the auxiliary tumblers positioned at the roots of the elongated accommodation holes are moved longitudinally of the elongated holes and pushed toward the upper tumbler bore side through function of the tapered part in continuation to the roots, then, while keeping the set/reset member in the situation of being pushed, the inner cylinder is turned to a position that the upper tumbler bores and the lower tumbler bores face with each other, so that the auxiliary tumblers having been temporarily held in the accommodation holes are returned to an initial position between the upper and the lower tumblers.

    摘要： A lock assembly includes a lock cylinder, for actuating a latch assembly, including a lock sleeve, first and second lock rotors, having first and second keyways respectively, rototably fitted in the lock sleeve, and a plurality of tumblers for locking up the first and second lock rotors. A key includes a key head having predetermined locking serrations arranged in such a manner that when the key head is inserted into the first keyway, the locking serrations are adapted to unlock the first lock rotor and enable the first lock rotor freely rotating until the first keyway is aligned with the second keyway, simultaneously, the key head being adapted to insert into the second keyway such that the locking serrations are adapted to unlock the second lock rotor to enable the second lock rotor to freely rotate to control the locking and unlocking of the latch assembly.

    摘要： A lock assembly includes a lock shell, at least first and second key plugs, at least first and second tumbler means, and a key for operating the first and second tumbler means. The lock shell has a front end, a rear end, and an accommodation hole extending from the front end to the rear end. The first and second key plugs are aligned axially and are mounted rotatably within the accommodation hole of the lock shell. The first and second key plugs respectively have first and second key ways. The first and second tumbler means are used for positioning respectively the first and second key plugs against the lock shell when the lock assembly is in a locked position. The key can operate the first and second tumbler means so as to rotate the first and second key plugs simultaneously. The first and second key ways are aligned for extension of the key from the first key way to the second key way when the first key plug is turned a predetermined angle relative to the second key plug by operating the first tumbler means. The second key plug is rotatable after the first and second key ways are aligned with each other.
