MECHANICAL KEY DEVICE CAPABLE OF FORMATION

摘要

PURPOSE:To make it possible to form very large keyways by moving a plurality of pin tumblers to different positions, and forming keyways having different projections and recesses when a large number of keyways to unlock by interlocking with locks are formed. CONSTITUTION:A key device capable of formation is so constructed that a keyway pin thread 14 and a pin core 15 are formed at free positions from a keyway pin 13 in a keyway 12, and a keyway base 10, a pin receiving base 11 and a lock plate 16, etc., are provided. It is so formed that the keyway pin core 15 is formed of a substance fixed with the lock plate 16 in a state to expose the keyway 13 to the outside and that the keyway pin thread 14 is formed of a substance fixed with the lock plate 16 in a state to enter the keyway 13. According to the constitution, a plurality of keyway pins 13 capable of moving can form various kinds of projections and recesses through different movements respectively.
