Patent attributes
A support system including opposed flanged rollers (6) for guiding a moving shelf. Coupling members (23) co-operate with the flanged rollers to present co-axial inwardly projecting stub shafts (22). A support (27) is provided for each coupling member. The ends of a layshaft (21) are telescopically engageable with the free ends of the stub shafts, and relative rotation between the stub shafts and the layshaft and between the coupling members and the rollers is prevented. The assembly of coupling members, supports and layshaft is reduced axially, by the telescopic engagement, to locate between the opposed rollers. The assembly is expanded axially for the coupling members to co-operate with the rollers in a manner to ensure co-rotation. The supports are mounted on an underlying base (1), rotationally to carry the coupling members so that load on the rollers is transferred to the supports.
