Abstract: A play system floor includes a frame defining the periphery of an area to be floored and a webbed flooring constructed of a webbing material extending between the frame members. The webbing material has an optimal predetermined stretch coefficient at which it retains its resiliency, while resisting sagging. The webbed flooring is sized using the stretch coefficient whereby the dimensions of the webbed flooring when stretched substantially correspond to the dimensions of the area to be floored. The webbed flooring is stretched to the dimensions of the area to be floored and secured to the frame. The floor is stretched to the dimensions of the area to be floored by positioning a bar through loops on each side of the weaved flooring, and applying tension to each bar. The webbed flooring is secured to the frame by attaching each bar to the frame using clamps, bands, or other attaching devices. Tension to each bar is applied by operating a screw-actuated clamping member to tighten the bar against the frame.

Abstract: A fabric web having a high modulus of elasticity is used as a spring element in an upholstered article such as a seat or a bed. The fabric web is joined to a metal rod serving as a frame member of the upholstered article by an end portion of the fabric web, which is folded on itself over the metal rod to provided folded and unfolded layers that are united together by means of a heat-fusible resin film. The heat-fusible resin film is held against the inner surface of the folded end portion of the fabric web and fused by high-frequency welding. The folded end portion of the fabric web is protected by the intermediary film against damage which would otherwise be caused by abrasive contact with a rust layer on the metal rod. The film sandwiched between the folded and unfolded layers has opposite ends folded and fused over the unfolded layer of the fabric web for reinforcing marginal edges of the fabric web.

Abstract: Fixing device for a covering (9), especially a covering of a seat, comprising on the one hand a profiled section (1) having longitudinal slots (15), and on the other hand an edging wire (17, 17a) bent at at least two places to form fasteners (19, 19a) intended to cooperate with the slots, the fasteners (19, 19a) lying generally in a plane inclined to the axis of the edging wire (17, 17a) and being capable of deforming by twisting during their entry into a slot (15) in the profiled section, but resiliently recovering their initial shape and their inclined position after this insertion.

Abstract: A folding chair has three U-shaped frame members supporting the seat and back rest and providing arm supports, and two connecting links controlling folding and unfolding for storage and use. Flexible material for the seat and back rest is removably attached to two cross members and to one frame member. Two frame members which form the legs cross and are pivoted together at the sides of the chair, and fold or scissor together front-to-back for folding and storage of the chair. The base of the U of the third frame member in a use position extends across the chair behind the back rest, and the sides form arm rests and extend forwardly to pivot connections at the front of the chair. A pair of links joins and supports the arms adjacent the rear frame member. For storage, the arm frame moves rearwardly and down about the links, folding the two leg frames together until the front pivot connections pass behind the back rest. The arm frame and links lock the first and second leg frame members together.

Abstract: The invention is an improved method and structure for rebuilding damaged and worn seats, such as seats for automotive equipment or vehicles. The structure of the present invention avoids the use of coil spring and "snake-like" wire springs in the rebuilding method and structure. The structure consists of a plurality of strap-like strips of steel or other suitable material woven into a net-like pattern with the ends thereof securely fastened around the existing seat frame. An alternative net-like pattern provides for a slight elevation of the control portion of the woven net-like pattern to provide an extra cushion effect.
