PCT No. PCT/FR96/01923 Sec. 371 Date Jun. 5, 1998 Sec. 102(e) Date Jun. 5, 1998 PCT Filed Dec. 3, 1996 PCT Pub. No. WO97/21898 PCT Pub. Date Jun. 19, 1997A self-opening and self-closing device enabling entry into a controlled access area includes a gate with two laterally retractable panels that may be opened by inserting a ticket or access card into a control mechanism. Each of the panels is controlled by a respective motor operated by the control mechanism. Each panel is secured to at least two runner members that are each operated by a roller secured to a link arm. The link arms are rotationally interconnected and rotated by the respective motor. Simultaneous rotation of the arms in opposite directions moves the two panels together (or apart) and thus closes (or opens) the entry device by moving each panel into a position in which it is locked by the respective arm in the horizontal position.
