Abstract
A combination lock includes a locking mechanism, a code identifying member, and a plurality of user rotatable dials, with a recess disposed on an outer periphery of each dial. The locking mechanism includes a plurality of dial engaging members configured to hold the locking mechanism in a locking position. When each of the dials is rotated to an unlocking orientation, the recesses align with the dial engaging members, allowing the locking mechanism to move from the locking position to an unlocking position. When the code identifying member is moved to a code identifying condition, the dial engaging members are in biased engagement with the dials, such that rotation of any one of the dials to the unlocking orientation causes the corresponding dial engaging member to engage the corresponding recess to provide a perceptible indication that the dial is in the unlocking orientation.
