Claim 17:
18. The security device according to claim 17
wherein the hinge structure further comprises a hinge, a spring mechanism, and a spring latch mechanism;
wherein the hinge is a fastening structure;
wherein the hinge attaches the first arm blade to the master blade such that the first arm blade rotates relative to the master blade;
wherein the hinge attaches the second arm blade to the master blade such that the second arm blade rotates relative to the master blade;
wherein the spring mechanism is a mechanical structure;
wherein the spring mechanism attaches to the first arm blade and the second arm blade;
wherein the spring mechanism provides the motive forces that rotate the first arm blade away from the master blade when the key structure fully inserts into the locking structure;
wherein the spring mechanism provides the motive forces that rotate the second arm blade away from the master blade when the key structure fully inserts into the locking structure;
wherein the spring latch mechanism is a mechanical structure;
wherein the spring latch mechanism controls the rotation of the first arm blade relative to the master blade;
wherein the spring latch mechanism controls the rotation of the second arm blade relative to the master blade;
wherein the spring latch mechanism locks the first arm blade into a fixed position within the hollow storage structure of the master blade until the key structure is fully inserted into the locking structure;
wherein the full insertion of the key structure into the locking structure releases the spring latch mechanism such that the first arm blade rotates into the first arm blade slot;
wherein the removal of the key structure from the locking structure resets the spring latch mechanism such that the spring latch mechanism relocks the first arm blade into position within the master blade;
wherein the spring latch mechanism locks the second arm blade into a fixed position within the hollow storage structure of the master blade until the key structure is fully inserted into the locking structure;
wherein the full insertion of the key structure into the locking structure releases the spring latch mechanism such that the second arm blade rotates into the second arm blade slot;
wherein the removal of the key structure from the locking structure resets the spring latch mechanism such that the spring latch mechanism relocks the second arm blade into position within the master blade.
