Abstract
A mechanism for coupling a track rail to a substrate includes a rail plate and a base plate, where the rail plate surrounds the base plate. An overmolded coating is formed of a non-metallic material and encases the rail plate and the base plate. Related methodology is disclosed.
Claims16
A fastening mechanism for coupling a track rail to a substrate comprising:
- a rail plate formed of a metallic material and including a lower side structured to face a substrate, and an upper side including a rail support surface extending between a front edge and a back edge of the rail plate, and the rail plate further including an outer perimeter and an inner perimeter defining an opening;
- a base plate formed of a metallic material, the base plate including a first lateral end and a second lateral end having a first bore and a second bore formed therein, respectively, and each structured to receive an anchor extending into the substrate, and the base plate being positioned within the opening such that the rail plate surrounds the base plate and a gap extends peripherally between the rail plate and the base plate;
- and
- an overmolded coating formed of a non-metallic material that is resiliently deformable relative to the metallic material, and the overmolded coating encasing the rail plate and the base plate and at least partially filling the gap to resiliently couple the rail plate and the base plate together.
