Abstract:
A combination lock comprising:a housing, a locking bolt with at least one leg portion extending into the housing and formed with a locking latch, and a locking breach for arresting said locking latch; at least one locking assembly rotatably supported within the housing; each locking assembly comprising a disc member formed with a peripheral recess, a cam wheel formed with cam teeth, and a reset cam; a locking member formed with at least one locking lug, each corresponding with a disc member; said locking member being angularly displaceable between an un-locked position in which all the at least one looking lugs are engaged within the peripheral recess of the corresponding disc member and wherein the locking breach is disengaged from the locking bolt; and a locked position in which at least one of the locking lugs is disengaged from the corresponding peripheral recess, wherein the locking breach arrests the locking bolt; a reset mechanism comprising a reset member for applying force on the reset cam of each of the at least one locking assembly, to thereby rotate the associated disc member into a reset position; a single manipulating member comprising at least one follower corresponding with each cam wheel and being planarly displaceable within the housing; the arrangement being such that upon predetermined consecutive displacements of the manipulating member corresponding with a combination code of the lock, the at least one follower encounters the cam teeth of a respective cam wheel, entailing corresponding consecutive angular displacement of each of the at least one locking assembly into a position in which each of the peripheral recesses faces a corresponding locking lug, thus allowing the locking member to shift into the un-locked position.
