Abstract
The present invention is directed to a caster assembly for supporting an object. The assembly includes a caster wheel, a support member rotatably supporting the wheel and first and second side support pieces mounted on the support member. The support member includes a base support surface for engaging and supporting a bottom surface of an object. The first side support piece includes a first support surface adapted to engage and support a first side surface of the object. The second side support piece includes a second support surface adapted to engage and support a second side surface of the object. At least one of the side support pieces is slidably mounted on the support member and is adapted to be moved relative to the other side support piece to permit adjustment of a distance between the between the first and second side support surfaces to accommodate objects of different widths.
