Abstract
A portable assembly for compact storage and to facilitate portability wherein a body is constructed of longitudinal parallel transversely aligned tubular frame members (A) for telescopically positioning an extensible handle (B) with brackets (C) being moved for longitudinally sliding movement on longitudinal body members (A) for carrying wheels (D) which are locked in position opposite each other beneath a medial portion of the load utilizing fasteners (E) without the necessity for utilizing a transverse axle.
Claims4
A portable load bearing cart assembly comprising:
- an elongated horizontal body having a pair of elongated longitudinal transversely aligned side members constructed of structural material;
- an elongated handle carried on said elongated horizontal body for longitudinal adjustment thereon;
- a pair of brackets slidable longitudinally on respective elongated longitudinal aligned side members;
- a wheel foldably carried by each bracket having a diameter comparable to the width of the cart receivable adjacent said body when said brackets and wheels carried thereby are moved adjacent respective ends of said body;
- a net extending across and aligned on said body for receiving a load thereacross;
- and
- fastening devices adjustably positioning said brackets in fixed intermediate positions on respective elongated longitudinal aligned members opposite each other for bearing a load on said wheels;
- whereby said brackets and wheels may be folded up in longitudinal alignment adjacent said body with said handle carried in a retracted position thereon for transport and assembled with the handle extended and with the wheels in an intermediate portion of the body tending to balance a load with the body in a generally horizontal position for transporting a load.

The method of assembling a portable load bearing cart comprising the steps of:
- providing an elongated horizontal body having a pair of elongated longitudinal transversely aligned side members constructed of structural material;
- extending an elongated handle carried by said elongated longitudinal body from a retracted position thereon;
- providing a pair of wheels carried by respective slidable brackets each wheel having a diameter comparable to the width of the cart receivable adjacent said body when said brackets and wheels carried thereby are positioned adjacent respective ends of said body;
- folding said wheels downwardly from a position adjacent the body;
- sliding each of said brackets longitudinally on respective elongated longitudinal aligned side members toward a position in transverse alignment in an intermediate portion of said body, one of said brackets being moved toward the handle;
- locking said brackets in a fixed intermediate use position on respective elongated longitudinal aligned members, with said wheels down in transverse alignment opposite each other;
- whereby said brackets and wheels may be folded up adjacent said body with said handle carried in retracted position thereon for transport and assembled with the handle extended and with the wheels in an intermediate portion of the body tending to balance a load in substantially horizontal position during transport of the load.
