WHEEL BRACKET ASSEMBLY ABSTRACT OF THE DISCLOSURE 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 down- wardly 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 approxi- mately 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 adja- cent 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 respect- ive side flanges of the upper bracket. Progressive pivotal movement of the wheel carrying bracket is countered by progressively increasing resistance from the resilient element.
