Abstract: A cart may include a first set of lower support arms and a second set of lower support arms, each of the lower support arms having a wheel attached thereto; a first set of upper support arms and a second set of upper support arms; a holding frame coupled to the first set of upper support arms and the second set of upper support arms; a locking mechanism; and a folding mechanism configured to allow the cart to transition between a folded position and unfolded position. During transition, the first set of upper support arms may be moveable relative to the second set of upper support arms; the first set of lower support arms may be moveable relative to the second set of lower support arms; and the first set of upper support arms may be moveable relative to the first set of lower support arms.

Abstract: A weight training sled and wall hanging bracket set for supporting the weight training sled in an elevated vertical stowage position. The push handles on the sled are pivotable as a unit about a laterally extending pivot axis as between an upward use position and a lowered stowage position extending towards the second longitudinal end of the chassis. The wall hanging bracket set includes an upper bracket for attachment to a vertical surface and supportively contact a second longitudinal end of the sled at two laterally spaced contact points, and a lower bracket for attachment to the vertical surface and supportively contact a first longitudinal end of the sled at a single contact point.

Abstract: According to an example aspect of the present disclosure, there is provided a novel caster assembly for a roll container (1000). The caster assembly has a caster (410) with a fork (411) as well as a pin (414). The pin (414) may be repeatedly attached to and removed from the fork (411) so as to attach the chassis (100) of the roll container (1000) to the fork (411). The pin (414) also acts as the hinge pin of a pivotable side wall (200) of said roll container (1000).
