Abstract
A wheel bracket assembly includes an upper bracket having two spaced downwardly extending side flanges and a wheel carrying bracket pivotally supported between the upper bracket side flanges for pivotal movement about an axis. The second bracket has a generally horizontal top plate with a transverse, upwardly facing, concave groove and has side flanges which extend downwardly from opposite sides of the top plate and are adapted to pivotally support a wheel therebetween. Pivotal movement of the wheel carrying bracket in one direction is resisted by a resilient element which has one end engaging the top plate at a location within the groove, which extends away from such location approximately along the path of movement of the location about the pivot axis, which tapers in thickness toward such end, which has a semicylindrical head at the opposite end, and which has a transverse groove on each side thereof adjacent the head. An omega-shaped clip securely grips around the head with its legs disposed in the transverse grooves, and has its ends securely supported on respective side flanges of the upper bracket. Progressive pivotal movement of the wheel carrying bracket is countered by progressively increasing resistance from the resilient element.
