<p><P>PROBLEM TO BE SOLVED: To effectively show the effect of theft prevention by preventing the key hole of a lock from being directly touched or peeped by concealing the key hole. <P>SOLUTION: An outer frame is installed on one side of the lock, and a storage space is formed in the outer frame. A displacement body is movably inserted into the storage space, and comprises a fitting space and a through hole. The through hole is formed so as to be aligned with the key hole by the displacement of the displacement body. A key introduction seat is movably inserted into the fitting space, and an insertion hole is formed in the key introduction seat. A fixed body having an insertion hole into which the key is inserted is installed on the displacement body, and a through hole and a storage part are formed in the fixed body. A connection rod is formed so as to extend through the through hole and the storage part. One end of the connection rod is rotatable, and the other end thereof has a connection part. The connection part is so formed that the key performs the unlocking and locking of the lock by fitting to the key for moving and rotating the key. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
