<p><P>PROBLEM TO BE SOLVED: To automatically turn a key to a key insertion position through a connection body just by holding an outer cylindrical body and bringing a distal end of the connection body close to a keyhole of a lock. <P>SOLUTION: A lock key insertion aid is for rotating a key freely rotatably held by an operation outer cylindrical body in a direction matched with the keyhole when a distal end of the key and the keyhole of the lock provided on a door do not match when inserting the key. A part to be engaged is provided inside a rear end of the operation outer cylindrical body, a connection body having an engaging part which can be engaged and disengaged to/from the part to be engaged at an inner end is supported by the operation outer cylindrical body so as to be freely rotated and moved back, and the connection body is energized in the direction of projecting from a distal end opening of the operation outer cylindrical body by a return spring equipped inside the operation outer cylindrical body. Further, a second magnetic body which performs adsorption corresponding to a polarity of a first magnetic body provided on a keyhole side is provided on a projecting distal end of the connection body, and the key is engaged with the connection body so as to be rotated together. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
