Abstract: A framing system is disclosed made of frame members and joint members. The frame members are of U-section and the ends are inserted into and imprisoned in the open ends of the joint members which are L-shaped, T-shaped, V-shaped, X-shaped or Y-shaped. The joint members are paired polystyrene mouldings which close together with a friction fit but which can be prised apart with a screwdriver. Assembled frames can be interconnected by link members inserted into the joint members. The linkage permits the construction of folding frames and boxes. Pictureframing, panelling, shopfitting and special exhibit work are disclosed.
