Abstract
PURPOSE: To make changeover to manual operation without the need of special mechanism by rotation by rotation-elevating a door through a support arm rotated by a motor while giving a counter-gravity directional moment by an urging member. CONSTITUTION: Two pillars 31, 32 are formed respectively by upper members 31a, 32a joined to axial fulcrums 41, 42 and a lower members 31b, 32b fixed to the ground. In the next place, the upper members 31a, 32a are vertically urged upward with respect to the lower members 31b, 32b by means of urging members 61, 61'. Subsequently, there are provided with support arms 21, 22 joined to the axial fulcrums 41, 42 in each one end 21a, 22a, and then a door 1 is crossed over the open end. Then, a motor M is rotated positively reversely so that the door 1 is elevation-rotated through the rotation of support arms 21, 22 while giving reaction directional moment by the urging members 61, 61' via a loosely movable lever 71. Also, the stop position is appropriately selected by an electronic circuit.
