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. When the combination code is coded in an opening combination, the stopping plate of the locking module, biased by the stopping plate spring, returns to a normal position whereby ceases blocking action against the movement of the locking plate and the lock is in "unlocked" status. The shackle can then be removed from the lock body by depressing the triggering button.

[ What is claimed is:] [1.] A resettable combination coded U-shackle lock assembly, comprising(a) a U-shaped shackle having a pair of legs, a cone-shaped locking pin provided at the end of each said legs in which a retaining groove is provided at an upper portion of each said locking pin;(b) a cross bar lock body being used to lock said pair of legs across open ends of said shackle, including:(1) a housing having a pair of openings at a top surface for receiving said locking pins of said U-shaped shackle and a rectangular opening at a middle bottom portion of said housing;(2) a locking plate slidably mounted in an upper portion of said housing having a pair of holes corresponding to said locking pins, one end of said locking plate being biased by an axial force from a locking plate spring such that smaller hole portions of said holes are engaged with said retaining grooves of said locking pins to lock up said U-shaped shackle, the other end of said locking plate being connected with a triggering button such that the engagement between said smaller hole portions and said retaining grooves are released when said triggering button is depressed; and(3) an integrally manufactured combination coded locking module provided inside said rectangular opening at the middle bottom portion of said housing, said locking module including a reset button for resetting the combination codes, a plurality of dials accompanying bushing sleeves and a stopping plate for controlling the movement of said locking plate, wherein when said dials are randomly disposed and the code is in locking combination, said stopping plate will be in blocking position such that said locking plate is blocked from axial movement to release said locking pins, wherein when said dials are disposed at the code of opening combination, said stopping plate is returned to a normal position by a stopping plate spring such that said locking plate is free for axial movement, then said triggering button is to be depressed to release the engagement between said smaller hole portions of said holes of said locking plate and said retaining grooves of said locking pins;(4) means for securing said locking plate and said combination coded locking module within said housing of said cross bar lock body.
