Claim:
A mobile storage system, comprising: a rail arrangement including a support surface and a laterally extending lip that defines an engagement area laterally offset from the support surface; a movable member adapted to be supported by the rail arrangement, wherein the movable member includes a wheel arrangement adapted to engage the support surface for movably supporting the movable member on the rail arrangement; and an anti-tip arrangement interposed between the rail arrangement and the movable member, comprising a pivotable anti-tip member carried by the movable member, wherein the anti-tip member includes a hook section and is pivotable about a pivot axis between an operative position and an inoperative position, wherein the hook section in the operative position underlies the engagement area of the rail arrangement to prevent tipping of the movable member relative to the rail arrangement, wherein the anti-tip member further includes a finger section spaced from the hook section, wherein the finger section overlies the lip of the rail arrangement and is adapted to be manually engaged by a user for placing the anti-tip member in the operative position, and wherein the anti-tip member further includes a retainer section that extends from the pivot axis in a direction opposite the finger section, and wherein the anti-tip arrangement further includes a releasable retainer member selectively engageable with the retainer section of the anti-tip member and the movable member for releasably retaining the anti-tip member in the operative position.
