Mechanical/electronic lock system which is manual with a handwheel or automatic with a stepper motor

摘要

Lock having a set of stationary plates (13, 14), made from epoxy glass with printed circuits joined together by the screws (9), which make it possible to pass, using a handwheel (1) or central pusher (2), which sends the command to the internal rotary contact (6), the codes to the various programmed circuits or to the fixed microcontrollers with the set which unbars an electromagnet (51) or electric keepers (65); this whole set forms a fixed unit, only the handwheel (1), with a new combination, makes it possible to be positioned facing either a code contact, an alarm, a zero-reset (reset to zero), a star, or an uncoded figure. Two models, a manual one with a handwheel (1); the other automatic, with a stepper motor, which allows automatic seeking of the codes; the start and the position of the codes are given by LED's (43, 44, 45); on the front face the position being sought is given by a double 7-segment display (52), fixed to the front face; these systems may replace all models of keyboards, whether these are "matrix keyboards", "parallel keyboards" or "touch-sensitive (capacitance-type) keyboards", they may come in parallel with mechanical or electrical locks.
