ABSTRACT:
A power operated door which fits into a wall opening with an outer surface flush with the outer wall surface and displaceable upwardly to a horizontal open position by tilting the top of the door inwardly and then sliding it in vertical and horizontal tracks to the open position. A first drive mechanism on the door tilts it about a lower bearing and a second drive mechanism drives the door upwardly and downwardly by means of flexible connectors which pull upwardly and downwardly on the bottom of the door.
