Abstract
A trolley (10), primarily for use as a roll cage, includes a base (16) with wheels (18) and a frame (40) located above said base (16). Poles (28, 30, 32, 34) are used to join the frame to the base and a flexible member (14) such as a tarpaulin sheet with latching clamps or a ratchet strap, are used to create tension between the components, to ensure the integrity of the trolley and to reduce the generation of noise when the trolleys is moving in use.

A trolley comprising:
- a base having a plurality of wheels attached thereto;
- a frame in use located above said base;
- a plurality of connectors coupled to said frame and said base to join said frame to said base;
- and
- at least one flexible member attached to said plurality of connectors, wherein said at least one flexible member is pulled taut by coupling the plurality of connectors to said frame and said base so that the flexible member applies tension between the plurality of connectors to provide the trolley with structural integrity.
2 more elements
A trolley comprising:
- a base having a plurality of wheels attached thereto;
- a frame located above said base;
- a plurality of poles coupled to the base and the frame, the plurality of poles having an outer surface comprising an interior surface portion that faces an interior of the trolley and an exterior surface portion that faces an exterior of the trolley;
- and
- at least one flexible member extending around the exterior surface portions of the plurality of poles, and wherein engagement of the plurality of poles to the base and the frame pulls the at least one flexible member taut so that the at least one flexible member creates tension between said base, said frame, and said poles.
