Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
Lock apparatus comprising a housing, a locking member supported in said housing for movement between locked and unlocked positions, said housing and locking member having aligned bores, blocking means supported in each of said aligned bores 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 means blocks movement of the locking member relative to the housing, a plate-like key member, a plate-like code member, said housing being provided with two slots each for respectively receiving one of said plate-like members, said bores in the housing and locking member being arranged in a pre-determined pattern, said plate-like members having respective regions corresponding to the location of said bores in said pattern, said plate-like members when inserted in said slots positioning said regions in superposed relation with one another for cooperating with said blocking means, the thickness of the card-like members in said regions being correlated in a code such that the combined thickness of said plate-like members in the superposed regions is different from the combined thickness of said plate-like members outside the superposed regions to constitute means for acting on said blocking means to mechanically move the same to said first position when said code corresponds to the pattern of the bores.
Claim 2
Dependent Claim
218 words
Lock apparatus comprising a housing, a locking member supported in said housing for movement between locked and unlocked positions, said housing and locking member having aligned bores, blocking means supported in each of said aligned bores 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 means blocks movement of the locking member relative to the housing, a plate-like key member, a plate-like code member, said housing being provided with two slots each for respectively receiving one of said plate-like members, said bores in the housing and locking member being arranged in a pre-determined pattern, said plate-like members having respective regions corresponding to the location of said bores in said pattern, said plate-like members when inserted in said slots positioning said regions in superposed relation with one another for cooperating with said blocking means, the thickness of the card-like members in said regions being correlated in a code such that the combined thickness of said plate-like members in the superposed regions is different from the combined thickness of said plate-like members outside the superposed regions to constitute means for acting on said blocking means to mechanically move the same to said first position when said code corresponds to the pattern of the bores.
Claim 3
Dependent Claim
32 words
A lock arrangement as claimed in claim 1 wherein the combined thickness of the plate-like members in the superposed regions is half the combined thickness of the plate-like members outside said regions.
Claim 4
Dependent Claim
57 words
A lock arrangement as claimed in claim 1 wherein one of said plate-like members has holes in some of said regions and the other plate-like member has holes in the remainder of said regions such that when the cards are superposed in each of said regions there will be only one hole in one of the cards.
Claim 5
Dependent Claim
37 words
A lock arrangement as claimed in claim 1 wherein said blocking means comprises a plurality of elements in each bore, at least one element being positioned to be engaged by the key member and the code member.
Claim 6
Dependent Claim
23 words
A lock arrangement as claimed in claim 4 wherein said key member and code member engage said one element at opposite sides thereof.
Claim 7
Dependent Claim
15 words
A lock arrangement as claimed in claim 4 wherein said one element is a ball.
Claim 8
Dependent Claim
65 words
A lock arrangement as claimed in claim 4 wherein said elements of the blocking means in each bore include pin elements and ball elements, said plate-like members cooperating with the ball elements to displace the pin elements, the pin elements having a junction surface which is aligned with a mating surface between the housing and locking member in said first position of the locking means.
