Track fastener

Track fastener apparatus having an unlocked and locked configuration for use with a locking track with an upper surface portion having an upper and lower surface with a slot with spaced cut-out portions extending through the upper surface portion from the upper to the lower surface thereof comprising:

• a track fastener housing having an upper portion and a lower portion and a threaded aperture extending from the upper portion to the lower portion thereof;
• means connected to said housing for exerting pressure against the lower surface of the upper surface portion of said locking track at two separate locations along said locking track between said spaced cut-out portions when said track fastener apparatus is in the locked configuration;
• said means for exerting pressure against the lower surface at two separate locations along said locking track comprising two separated track studs each having an upper portion connected to the lower portion of said track fastener housing on opposite sides of the threaded aperture in said track fastener housing and each having an enlarged lower end portion adapted to fit into the cut-out portions of the upper surface portion of said locking track;
• plastic sliding means located on the lower portion of said track fastener housing in position to bear upon the upper surface of the upper surface portion of said locking track when said track fastener apparatus is in the unlocked configuration for reducing friction and permitting said track fastener apparatus to be slid along the upper surface of the upper surface portion of said locking track;
• and means for exerting a force against the upper surface of the upper surface portion of said locking track in the vicinity of one of said spaced cut-out portions when said track fastener apparatus is in the locked configuration;
• said means for exerting a force against the upper surface in the vicinity of one of said spaced cut-out portions including a track wedge member with an upper surface having a centrally located aperture extending to the upper surface and a locking screw having an unthreaded portion with an end portion sized to slip into the aperture in said track wedge member, said locking screw having an enlarged section located adjacent to the end portion creating a shoulder adapted to contact and exert force upon the upper surface of said track wedge member and a cylindrical threaded portion insertable into the threaded aperture extending from the upper portion to the lower portion of said track fastener housing;
• said track wedge member having a lower portion sized to be received in the cut-out portions of the upper surface portion of said locking track and an enlarged upper portion adapted to contact the upper surface of the upper surface portion of said locking track in the vicinity of the cut-out which receives the lower portion of said wedge member when said track fastener apparatus is in its locked configuration.
