MULTISIDED KEY AND LOCK

摘要

A system includes a multisided key with three or more sides, where all the sides of the multisided key are identical. Further, the system includes a cylindrical lock with inner and outer cylinders and a locking vane residing radially outward in a void spanning the inner and outer cylinders. The locking vane includes an inner portion including a first protrusion and a second protrusion corresponding to two levels of the multisided key and an outer portion separated from the inner portion by a gap, wherein at least a part of the outer portion is disposed in the outer void. When the multisided key is inserted into the lock, the gap of the locking vane aligns with an interface between the inner and outer cylinders, allowing the inner cylinder to rotate within the outer cylinder.

1. A system comprising:
a multisided key including:
a head; anda shaft coupled to the head, the shaft including:
a length;a tip at an end of the length opposite the head;levels along the length such that each side of the multisided key is identical at each of the levels; andtransitions between the levels; a lock comprising:
an outer cylinder including an outer void;an inner cylinder including an inner void and a keyhole sized to allow the multisided key to enter the inner cylinder, wherein the inner cylinder is disposed inside the outer cylinder and the outer cylinder and inner cylinder meet at an interface;a locking vane disposed radially outward from a center of the inner cylinder, the locking vane including:
an inner portion including a first protrusion and a second protrusion, wherein at least a part of the inner portion is disposed in the inner void and the first protrusion and the second protrusion correspond to two levels of the multisided key; andan outer portion separated from the inner portion by a gap, wherein at least a part of the outer portion is disposed in the outer void; anda spring coupled between the outer cylinder and the outer portion of the locking vane, wherein the spring pushes the locking vane such that the first protrusion resides in the keyhole when the multisided key is not in the keyhole.
