<p>A combination lock comprises a housing with a shackle having a short first leg whose end is adapted to selectively make locking engagement with the housing, and a substantially straight second leg received in an elongate bore in the housing. The straight leg is movable between a locking position in which it is held in the bore and holds the first leg end in locking engagement with the housing, and a release position at which the first leg end is disengaged from the housing. A mechanism selectively holds the straight leg in its locking position or allows it to move to its release position. This mechanism comprises a plurality of fins extending radially from and movable with the straight leg between its locking and release positions, and an equal plurality of dials, each dial being selectively movable to a specific orientation which allows movement of a fin. When each dial is in its specific orientation the straight leg is free to slide to its release position and disengages the first leg end from the housing.</p> |
