ABSTRACT "An undercarriage arrangement for normally static articles" An undercarriage arrangement for normally static objects such as work-benches comprises at least one pair of wheels or rollers which are mounted for rotation on at least one support member pivotably mountable on the object. A spring biassing arrangement is provided, one end of the spring being pivotally mounted on the support member and the other end thereof being attached to means mounted on the object. The means may comprise a pivotal lever or projections. In either case, the second end of the spring 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 For the at least one support member. The two end positions for the second end of the spring are so selected that, in one position, the wheels are located generally above the lowermost portion of the object and, in the other position, are located generally below the lowermost portion of the object. The displace- ment of the second end of the spring thus enables any static abject 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.
