Abstract:
In an apparatus for supporting a cover suspended over a crossbar, the cover having first and second planer surfaces foldable about a hinge and opposing peripheral edges spaced from and extending substantially parallel to the hinge, the planer surfaces sandwiching the crossbar therebetween when folded with the peripheral edges oriented substantially together and below the crossbar when supported, said improvement comprising:engaging means supporting and engaging the peripheral edges; and tension means, connected between the crossbar and the engaging means and being sandwiched between the first and second planer surfaces supporting the cover with the hinge spaced above the wherein the hinge is and in a substantially stress free state, wherein the crossbar is part of a cover lifter, the crossbar extending transversely between arms rotatable about pivots between a resting position and a supporting position, and wherein, in the resting position, the crossbar is positioned on one of the first and second planer surfaces, substantially adjacent and parallel to the hinge and intermediate the hinge and the peripheral edge of the one of the first and second planer surfaces, and in the supporting position, the crossbar is sandwiched between the first and second planer surfaces and the hinge is positioned above the crossbar.
