Abstract:
Lock apparatus comprising a housing in which is movably supported a locking member for movement between locked and unlocked positions. The housing and locking member have aligned bores containing blocking pins supported for movement between a first position in which the locking member is movable relative to the housing and a second position in which the blocking pins block movement of the locking member relative to the housing. A plate-like key member and a plate-like code member are respectively insertable into slots provided in the housing. The bores in the housing and locking member are arranged in a predetermined pattern and the plate-like members have respective regions corresponding to the location of the bores in the pattern. The key and code members are provided with holes at the regions corresponding to the location of the bores in such an arrangement that there is one thickness of material of a card at each bore whereas at the remainder of the card outside the regions corresponding to the bores, there are two thicknesses of material. The differences in the thickness of material is employed to mechanically move the blocking pins to the first position when at each of the regions corresponding to the bores there is but a single thickness of material.
