Combination lock
First Claim
1. A dial code combination identifying lock comprising:
- a lock body;
a plurality of dials assembled with the lock body, each comprising an unlocking feature, each of the plurality of dials being rotatable to an unlocking orientation;
a locking mechanism disposed within the lock body and movable between a locked position and an unlocked position when all of the plurality of dials are in the unlocking orientation;
a shackle having a long leg retained within the lock body and a short leg lockably securable within the lock body when the locking mechanism is in the locked position, and separable from the lock body in an axial direction along an axis defined by the long leg when the locking mechanism is in the unlocked position; and
a user operable code identifying mechanism movable between a code concealing condition and a code identifying condition while the shackle remains secured in the locked position, the code identifying mechanism comprising a plurality of separate dial engaging members each biased into engagement with the corresponding dial when the code identifying mechanism is in the code identifying condition, such that rotation of any one of the dials to the unlocking orientation causes the corresponding dial engaging member to engage the corresponding unlocking feature to provide a positive perceptible indication that the corresponding dial is only in the unlocking orientation independent of orientations of the other dials;
wherein the unlocking features comprise recesses on outer peripheries of each of the plurality of dials; and
wherein the locking mechanism comprises a blocking member slideable in the axial direction between the locked and unlocked positions, with each of the plurality of dial engaging members being configured to hold the blocking member in the locked position, further wherein when each of the plurality of dials is rotated to the unlocking orientation, each of the corresponding recesses aligns with each of the corresponding ones of the plurality of dial engaging members, allowing the blocking member to slide in the axial direction from the locked position to the unlocked position.

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.

8. A code identifying combination lock comprising:
-
a lock body; a plurality of user rotatable dials assembled with the lock body, each including an unlocking feature; a shackle having a long leg retained within the lock body and a short leg separable from the lock body in an axial direction along an axis defined by the long leg; a blocker disposed within the lock body and comprising a plurality of separate dial engaging members configured to hold the blocker in a locking position, wherein when each of the plurality of dials is rotated to an unlocking orientation, each of the corresponding unlocking features aligns with each of the corresponding ones of the plurality of dial engaging members, allowing the blocker to slide in the axial direction from the locking position to an unlocking position to permit separation of the short leg of the shackle from the lock body; and a code identifying member assembled with the blocker, the code identifying member being movable between a code concealing condition and a code identifying condition; wherein when the code identifying member is in the code identifying condition, each of the plurality of dial engaging members is in biased engagement with the plurality of dials, such that rotation of any one of the plurality of dials to the unlocking orientation causes the corresponding dial engaging member to engage the corresponding unlocking feature to provide a positive perceptible indication that the one of the plurality of dials is only in the unlocking orientation independent of orientations of the other dials. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
