Anti-reverse device for single person security door, has stud and grooves that are provided with blocking component controlled by module in locking/unlocking state to block/release pivoting of leaf beyond determined pivot angle

摘要

The device has contact or proximity sensors (6, 7) and encoder tracks (8, 9) for detecting angular pivoting ranges of a leaf (3) of a security door (1) to control transition between the ranges, and for sending detection signals representing the detected ranges to an electronic command and control module. A retractable abutment stud (10) and abutment grooves (11, 11') include a blocking component controlled by the module in locking or unlocking state according to the transition to block or release pivoting of the leaf beyond determined pivot angle and in pivot direction of the leaf. The contact or proximity sensors are inductive or photoelectric sensors. The encoder tracks are constituted of alternation of metallic sectors or non metallic sectors. Independent claims are also included for the following: (1) a security door comprises a leaf pivoted of 90 degrees to a plane of an opening of the door (2) a method for controlling and commanding an anti-reverse device.
