Self-cleaning, self-centering door track having an _integral mount

Claim 1

A door track for carrying a trolley supporting a door for rolling movement, comprising: a longitudinally extending top wall having a pair of parallel opposed side edges, said top wall being adapted for coplanar abutment with a generally horizontal surface such as a beam of a building; a longitudinally extending side wall depending from each of said side edges of said top wall, said side walls being identically shaped and oppositely facing, said side walls each including a planar upper portion joined to one of said side edges of said top wall so as to be disposed generally perpendicular thereto with said planar upper portions of said side walls extending to a point generally intermediate the uppermost and lowermost extremes of said side walls and being adapted for coplanar abutment with a generally vertical surface such as a header of a building, said side walls each also including a curved lower portion integral with the corresponding one of said planar upper portions so as to be disposed generally tangentially thereto with said curved lower portions of said side walls each extending along a continuous downward and inward curve to a point of termination at the lowermost extreme of said side walls and being adapted for self-centering of said trolley for non-binding rolling movement, said side walls being spaced apart at the lowermost extreme to define a longitudinally extending opening for freely receiving a door support of said trolley, said door track being self-cleaning by gravity and movement of said trolley; and integral mounting means associated with said longitudinally extending top wall and said longitudinally extending side walls, said mounting means associated with said top wall comprising a plurality of longitudinally spaced fastener-receiving openings, said mounting means associated with said side walls comprising a plurality of longitudinally spaced fastener-receiving openings, said fastener-receiving openings in said side walls comprising aligned pairs of apertures in said planar upper portions adjacent said top wall, whereby each of said aligned pairs of apertures in said sidewalls are adapted to have a single fastener extending therethrough.
