  • Patent number: 5787736
    Abstract: A resettable combination coded U-shackle lock assembly includes a cross bar lock body and a U-shaped shackle with its legs removably locked to the lock body. The lock body is disposed with a resettable combination coded locking module, a locking plate, a triggering button, and a locking plate spring. The locking plate, through its locking holes, engages the locking pins of the shackle by the biasing force exerted by the locking plate spring and disengages when the triggering button disposed on the other end of the locking plate is depressed to overcome the biasing force and causing the locking plate to move axially to release engagement with the locking pins. When the combination code is coded in locking combination, the axial movement of the locking plate is blocked by the stopping plate of the locking module and the lock is in "locked" status.
