COMBINATION LOCK
Document Type and Number:
Japanese Patent JP3558772
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable an unlock code to be set freely without removal of each dial.
SOLUTION: A wire part is provided at one end with a lock main body 3 and at the other end with a connection 4. The lock main body 3 is fitted over a plurality of lock gears 25 constituting a lock mechanism, in such a way that the lock main body 3 can displace a dial 26 in the direction of an axis. A meshing part having meshing positions by a number corresponding to the number of combinations of the dial 26 is formed between each lock gear 25 and the dial 26. Displacement of each dial 26 in the direction of the axis is restrained by a knob plate 47, and each dial 26 can be displaced in the direction of the axis by a predetermined amount when the knob plate 47 is loosened. When each dial 26 is displaced in the direction of the axis by the predetermined amount, it is disengaged from the lock gear 25, enabling an unlock code to be set.
