Patent number: 5375443Abstract: The present invention provides an improved lock device in which a slider is movable in either a locking direction or a releasing direction only when the amounts of projections of plural tumblers mounted on the slider correspond to the dimensions of plural holes punched in a lock card. When the lock card is slidingly inserted into a card groove under the release condition, the lock card successively presses a stopper disposed on the insertion side and the plural tumblers into tumbler chambers in the slider and then hits against a stopper disposed on the exit side, which projects into an adjustment groove. Here tapered tips of the tumblers are fitted into and engaged with the corresponding holes formed in the lock card, and engagement projections on the tumblers are all located in a sliding groove. The slider is thus movable together with the lock card.Type: GrantFiled: November 30, 1992Date of Patent: December 27, 1994Assignee: Tamura Plastic Mfg Co., Ltd.Inventor: Shinichi Tamura

Patent number: 4838058Abstract: Engaging pieces of plates pivotally mounted in a lock box are adapted to engage holes or cutouts formed in a slide member slidable between its locked and unlocked positions. When a right card formed with holes and cutouts in right positions is inserted into a card slot, the engaging pieces in engagement with the holes or cutouts are all pushed down by the card, pivot or pins and are disengaged out of the holes, while the engaging pieces out of engagement are not pushed by the card owing to the cutouts or holes in the card. Thus the slide member freed from the restraint by the engaging pieces can be slid to its unlocked position to open the lock. When a wrong card is inserted, the engaging pieces out of engagement with the slide member will be pushed by the card and engage the slide member, restraining it from moving. Thus the lock cannot be opened.Type: GrantFiled: July 7, 1987Date of Patent: June 13, 1989Assignee: Matsumoto Metal Mfg. Co., Ltd.Inventor: Haruo Matsumoto
