Claim 13:
14. The lock with key having expanding arm elements according to claim 13
wherein the plurality of lock mechanisms further comprises a first lock mechanism and a second lock mechanism;
wherein the first lock mechanism is a mechanical structure;
wherein the first lock mechanism locks the shackle into position such that the shackle binds the first object to the second object;
wherein the first lock mechanism mounts in the expansion cavity such that the first blade structure interacts with the first lock mechanism to release the lock on the shackle;
wherein the first lock mechanism further comprises a first plug, a first tumbler set, and a first mechanical linkage;
wherein the first plug is a c-channel that mounts in the expansion cavity such that the first plug will rotate within the expansion cavity;
wherein the first plug is sized and positioned such that the first blade structure will insert into the open lateral face of the first plug when the first lock mechanism locks the shackle into position;
wherein the key structure will rotate the first blade structure while the first blade structure is contained within the first plug such that the rotation of the first blade structure will rotate the first plug;
wherein the rotation of the first blade structure by the key structure while the first blade structure is contained within the first plug;
wherein the position of the first blade structure within the first plug is selected such that the first blade structure will appropriately interact with the first tumbler set while the first blade structure is inserted into the first plug;
wherein the first plug further comprises a first cam tab;
wherein the first cam tab is a mechanical structure that attaches to the first plug such that the rotation of the first plug will rotate the first cam tab;
wherein the first tumbler set is a set of lock tumblers that lock the first plug into a fixed position within the expansion cavity when the shackle is in the locked position;
wherein the first tumbler set is designed to interact with the first blade structure such that the rotation of the first tumbler set will not inhibit the rotation of the first plug within the expansion cavity when the appropriately keyed structure is used as the first blade structure;
wherein the first mechanical linkage is a mechanical structure;
wherein the first mechanical linkage forms a linkage between the first plug and the first shackle notch of the shackle such that the rotation of the first blade structure will rotate the first plug such that the lock of the first lock mechanism on the first shackle notch is released;
wherein the first mechanical linkage further comprises a first latch mechanism, a first compression spring, and a first plug tang;
wherein the first plug tang is an extension structure that mechanically attaches the first cam tab to the first latch mechanism;
wherein the first plug tang attaches to the first cam tab such that the rotation of the first plug pulls the first latch mechanism away from the first shackle notch to release the lock on the shackle;
wherein the first latch mechanism is a mechanical structure that is geometrically similar to the first shackle notch;
wherein the first latch mechanism and the first shackle notch are formed such that the insertion of the first latch mechanism into the first shackle notch will lock the shackle into a fixed position;
wherein the first compression spring is an energy storage device;
wherein the rotation of the first plug deforms the first compression spring as the first plug simultaneously pulls the first latch mechanism out of the first shackle notch;
wherein the first compression spring provides the motive forces that assist in reinsertion of the first latch mechanism into the first shackle notch the next time the shackle is locked into position;
wherein the second lock mechanism is a mechanical structure;
wherein the second lock mechanism locks the shackle into position such that the shackle binds the first object to the second object;
wherein the second lock mechanism mounts in the expansion cavity such that the second blade structure interacts with the second lock mechanism to release the lock on the shackle;
wherein the second lock mechanism further comprises a second plug, a second tumbler set, and a second mechanical linkage;
wherein the second plug is a c-channel that mounts in the expansion cavity such that the second plug will rotate within the expansion cavity;
wherein the second plug is sized and positioned such that the second blade structure will insert into the open lateral face of the second plug when the second lock mechanism locks the shackle into position;
wherein the key structure will rotate the second blade structure while the second blade structure is contained within the second plug such that the rotation of the second blade structure will rotate the second plug;
wherein the rotation of the second blade structure by the key structure while the second blade structure is contained within the second plug;
wherein the position of the second blade structure within the second plug is selected such that the second blade structure will appropriately interact with the second tumbler set while the second blade structure is inserted into the second plug;
wherein the second plug further comprises a second cam tab;
wherein the second cam tab is a mechanical structure that attaches to the second plug such that the rotation of the second plug will rotate the second cam tab;
wherein the second tumbler set is a set of lock tumblers that lock the second plug into a fixed position within the expansion cavity when the shackle is in the locked position;
wherein the second tumbler set is designed to interact with the second blade structure such that the rotation of the second tumbler set will not inhibit the rotation of the second plug within the expansion cavity when the appropriately keyed structure is used as the second blade structure;
wherein the second mechanical linkage is a mechanical structure;
wherein the second mechanical linkage forms a linkage between the second plug and the second shackle notch of the shackle such that the rotation of the second blade structure will rotate the second plug such that the lock of the second lock mechanism on the second shackle notch is released;
wherein the second mechanical linkage further comprises a second latch mechanism, a second compression spring, and a second plug tang;
wherein the second plug tang is an extension structure that mechanically attaches the second cam tab to the second latch mechanism;
wherein the second plug tang attaches to the second cam tab such that the rotation of the second plug pulls the second latch mechanism away from the second shackle notch to release the lock on the shackle;
wherein the second latch mechanism is a mechanical structure that is geometrically similar to the second shackle notch;
wherein the second latch mechanism and the second shackle notch are formed such that the insertion of the second latch mechanism into the second shackle notch will lock the shackle into a fixed position;
wherein the second compression spring is an energy storage device;
wherein the rotation of the second plug deforms the second compression spring as the second plug simultaneously pulls the second latch mechanism out of the second shackle notch;
wherein the second compression spring provides the motive forces that assist in reinsertion of the second latch mechanism into the second shackle notch the next time the shackle is locked into position.
