ABSTRACT:
A height or level adjusting device for use with a platform assembly, which platform assembly has a platform section and an upstanding cross brace member oriented between the platform section and a support surface. The cross brace member has a pair of laterally spaced, upstanding extensions thereon. A cross piece support member is provided as is a first mounting structure for facilitating a mounting of the cross piece support member on the cross brace member. A second mounting structure is also provided for facilitating a mounting of the platform section on the cross piece support member. A housing structure is provided at each end of the cross piece support member. Each housing has at least one open side forming an opening into an interior cavity of the housing structure and a bottom wall of the cavity. A pair of laterally spaced adjusting devices are provided on the cross piece support member and include guide structure on each of the housing structures and a plurality of stacked slider members, each movably guided on the guide structure. A movement of at least one of the slide members into the cavity will facilitate it being interposed between the upstanding extension and the bottom wall of the cavity to bring about a height or level adjustment of the platform assembly relative to the cross brace member.
