Support mechanism for a track system

A track system, comprising:

• a track member having an interior portion and an exterior portion;
• an elongate shaft mounted within the interior portion of the track member;
• at least one support mechanism mounted to the exterior portion of the track member, the at least one support mechanism comprising:
• a housing;
• an engagement feature having first and second engagement members spaced-apart from one another to define a receiving area therebetween, wherein the first and second engagement members are operable between deployed and retracted positions, and further wherein the elongate shaft is supported in the receiving area by the first and second engagement members when the first and second engagement members are in the deployed position, and further wherein the elongate shaft is spaced-apart from the receiving area when the first and second engagement members are in the retracted position;
• and
• a carriage assembly operably coupled to the elongate shaft for movement therealong by a coupling assembly, wherein the coupling assembly includes a slider bracket having at least one ramp portion configured to contact and guide the first and second engagement members from the deployed position to the retracted position as the carriage assembly is driven past the at least one support mechanism along the elongate shaft, and further wherein the at least one ramp portion includes a receiving aperture disposed therethrough, and further wherein the elongate shaft is received through the receiving aperture of the at least one ramp portion.
