Abstract
A trimless flush floor fitting for positioning at an opening in a floor or other structural member, at a level line of said structural member, the fitting comprising a leveling frame member and linkage members complementarily adjustably connecting the frame member with a bracket in said floor opening, whereby, on actuation of the linkage means, said leaving frame may be adjustably moved to conform to the level line of the structural surface, without the necessity of using complex and special trim accessories. No trim shows on the carpeting or other floor covering material, the latter being used without pieces being removed therefrom (as in prior practices). Architecturally there is only a minimum of clutter on the carpet surface, only the cables, when coming through the device being visible; when the device is not in use, it is completely invisible and concealed by the carpet, which is back in place.
