Abstract:
1. A counterbalancing assembly for an article of folding furniture which includes a furniture component that is pivotally secured to a support assembly for movement between a substantially upright storage position and a substantially horizontal use position, said counterbalancing assembly comprising: at least one piston extending between the support assembly and the furniture component, said at least one piston being biased to resist a downward force of gravity acting on the furniture component; an upper mounting bracket for securing a first end of the at least one piston to the support assembly, said upper mounting bracket including a worm gear and a mounting element that is threaded onto the worm gear, wherein the mounting element has a portion adapted to engage a complementary fitting defined by the first end of the at least one piston, and wherein rotation of the worm gear causes a corresponding linear movement of the mounting element, and thus, linear movement of the first end of the at least one piston relative to the support assembly; and a lower mounting bracket for securing a second end of the at least one piston to the furniture component.
