Compression tubes are sleeved on the draw rods and are longitudinally compressed between the end panels. Bumper frames are provided which have horizontal portions through which the draw rods extend.
Claims19
A cart comprising:
- a generally rectangular bottom panel assembly having bottom wheel mounts adjacent its corners;
- a generally rectangular top panel assembly spaced above said bottom panel assembly and including a plastic top panel with nut inserts fixed therein against rotation;
- said top and bottom panel assemblies including respective bumper frames having outwardly exposed bumper faces and having horizontal portions;
- vertical end panels extending between said top and bottom panel assemblies;
- and
- draw rod means extending vertically through the entire vertical length of said end panels and through said horizontal portions of said bumper frames, said draw rod means threadably engaging said nut inserts and engaging the bottom of said bottom panel assembly for clamping said top panel assembly and base panel assembly against the upper and lower ends, respectively, of said end panels.

A cart comprising:
- a generally rectangular bottom panel assembly having bottom wheel mounts adjacent its corners;
- a generally rectangular top panel assembly spaced above said base panel assembly;
- vertical end panels extending between said top and bottom panel assemblies;
- and
- draw rod means extending vertically through the entire vertical length of said end panels and engaging said top and bottom panel assemblies for clamping said top panel assembly and base panel assembly against the upper and lower ends, respectively, of said end panels;
- and compression tubes sleeved on said draw rod means and extending with said draw rod means through said end panels into engagement with said panel assemblies, said compression tubes being longer than said end panels so that the compression tubes are longitudinally compressed responsive to clamping of said panel assemblies against the ends of said end panels by said draw rod means.
