<p>This invention relates to one way door systems, in particular to door systems designed as entry/exit points addressing the problems of safety and security. A one way security door system for controllably restricting movement of a user along a path between an entrance and an exit is described. A plurality of moveable door panels are moveable along a forward path between the entrance and exit. The panels are also moveable in the return path between the exit and entrance. A moveable restricting mechanism restricts access along the return path to a user. At least one door panel in the forward path prevents a user moving beyond the door panel at any one time. A door panel is configured to open to permit access beyond the door panel upon reaching the exit. A drive system may drive the plurality of moveable door panels along the forward path and then the return path back to the entrance.</p> |
