Abstract
A stepstool (20) configured for mounting on a tire (22) includes a support frame configured to rest against an outer surface (40) of the tire (22). An outside lower platform (34) and an outside upper platform (36) are attached to the support frame. A first retaining bar (114) is configured to rest against an inner surface (42) of the tire (22), and first linking members (104 and 106) link the first retaining bar (114) to the support frame. The stepstool (20) further includes an inside platform (38) configured to releasably couple to the first retaining bar (114) and reside proximate the inner surface (42) of the tire (22). A second retaining bar (132) is configured to rest against the outer surface (40) of the tire, and second linking members (128 and 130) link the second retaining bar (132) to the inside platform (38). The first and second linking members are directed over an upper circumferential surface (122) of the tire (22) to hold the stepstool (22) securely on the tire (22).
