(54)	Roller suspension device for a horizontally-sliding door of a piece of furniture

(57) The roller suspension device for a horizontally-sliding door leaf of a piece of furniture comprises a stationary track-forming member having an upper and a lower running surface, and a movable leaf-supporting member provided with a leaf-supporting brace projecting from the front of the furniture piece, transversely to the direction of movement of the horizontally-sliding door leaf, and from which said horizontally-sliding door leaf is suspended. The movable leaf-supporting member has at least a pair of first and second co-axial supporting wheels for contacting said lower and upper running surface, respectively, of the track-forming member, and the lower and upper running surfaces in combination produce a pair of non-collinear parallel and oppositely directed reaction forces which act on said first and second co-axial supporting wheels, respectively, of the leaf-supporting member for generating a balancing moment which counterbalances the moment of the gravitational force acting on the horizontally-sliding door leaf.
