Abstract:
1. An automatic door actuating system for actuating a hinged door in opening and closing displacement, said system having a reversible electric motor mounted on the hinged door adjacent the free edge of the door, said motor being in driving relation with a pulley, said pulley engaging a tensioned flexible line, said line extending substantially horizontally between a first attachment point on a lintel portion of said door frame and a second attachment point on a surface located adjacent said door free edge when said door is in a fully open position; and means for energising said motor in a selected mode of opening and closing rotation, whereby, upon energization of said motor said pulley engages said line to draw said door in a respective opening/closing displacement; a gear wheel secured to said pulley for rotation therewith, and a toothed rack projecting from said lintel to engage said gear wheel when said door is in a substantially closed position, whereby with said gear wheel engaged by said toothed rack, said motor can displace said door relative to said frame, independently of said flexible line.
