Abstract

The apparatus enables a door to be moved into, out of and across an opening in a structure. A motor vehicle has upper, lower and intermediate guides 1, 7, 12 by which a door 6 is suspended and guided for movement by way of guide members 5', 8, 15 engaged with the guides. Curves 1', 7' at the front of guides 1, 7 guide the door into the opening. A door plate 14 and arm 16 constitute a hinge and the arm 12 is pivoted to the intermediate guide member 15. When the door is in the opening the arm 16 prevents downward pivoting of a carrier 19 on the intermediate guide member 15 whereby a roller 21 on the carrier is engaged with an abutment end 22 of the intermediate guide 12, preventing the intermediate guide member 15 engaged with it from sliding rearwardly along that guide 12. Initially, during opening, the curves of the upper and lower guides 1, 7 and the hinge 14, 16 cause movement of the door laterally out of the opening and to the rear. When the arm 16 clears the carrier 19 the latter can pivot down to allow the door to slide rearwardly. During closing, the carrier 19 prevents a forward pivoting of the arm 16 until the roller 21 rises to engage the abutment end 22, positioning and f…
