Abstract
The sliding door is constituted by at least one door-leaf which is stabilized by two parallel toothed racks disposed in meshing engagement with two pinions, the pinions being coupled together by means of a coordinating shaft surrounded by a connecting tube. Two crank-arms attached to the tube are pivotally mounted on a stationary structure which is attached to the door-frame. Operating means comprising a rotary motor and a mechanism for driving the pinions of the leaf-stabilizing system are rigidly fixed to at least one crank-arm, the motor being associated with an auxiliary pinion which is in mesh with one of the stabilizing pinions.
