Abstract: A prefabricated zero clearance fireplace includes a combustion chamber having a front opening, a glass door sized and shaped for positioning over and sealing the opening and a guide system for guiding vertical movement of the door between a lowered position over the opening and a raised position. The guide system includes tracks that are inwardly offset at their lowermost ends so that the door seals the combustion chamber without friction as the door is raised and lowered. Counterweights permit the door to be easily raised and lowered. For safety, the counterweights cause the door to automatically raise if it is pushed outwardly from the inside. The door is hinged for pivoting outwardly about a vertical axis in the lowered position. An optional motor can be provided for raising and lowering the door. A convection chamber surrounding the combustion chamber permits circulation and heating of room air.

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.
