摘要： An undercarriage arrangement for normally static objects such as work-benches comprises at least one pair of wheels or rollers (5) which are mounted for rotation on at least one support member (6) pivotably mountable on the object (1, 2, 3, 4). A spring biassing arrangement is provided, one end of the spring (11) being pivotally mounted (at 12) on the support member (6) and the other end thereof being attached to member (8) mounted on the object (1, 2, 3, 4). The member (8) may comprise a pivotal lever (8) or projections. In either case, the second end of the spring (11) can be displaced between two or more pre-selected positions with the proviso that at least two of the pre-selected positions are disposed on opposed sides of a vertical plane passing through the pivot axis (7) for at least one support member (6). The two end positions for the second end of the spring (11) are so selected that in one position the wheels (5) are located generally above the lowermost portion of the object (1, 2, 3, 4) and in the other position are located generally below the lowermost portion of the object (1, 2, 3, 4). The displacement of the second end of the spring (11) thus enables any static object to which the arrangement is fitted to be transposed from a conventional static mode into a transportation mode and, once transported returned to its conventional static mode.
