Abstract: A process for producing an upholstered article in a bladder mold. A cover sheet with adhesive is positioned over the opened bladder mold. A foam core is inserted into the bladder mold, carrying the cover sheet into engagement with the bladder. The bladder mold is then closed so that the bladder wraps the marginal portion of the cover sheet around the foam core. After the adhesive cures to bond the cover sheet to the foam core, the mold is opened; and the article is removed.

Abstract: A deck plank in the form of an elongated plastic channel having a mounting base, upright side walls terminating in cap engaging locking means and intermediate support means between the side walls, at least the upright side walls having a honeycomb structure, and a longitudinal generally planar plastic cap for closing the channel having edge formations adapted to engage and interlock with the side wall locking means. In its preferred form the entire channel is of a honeycomb structure, the channel wall cap engaging locking means are arcuate sockets and the cap edge formations are depending arcuate legs adapted to snap into the wall sockets.

Abstract: The invention concerns a dismountable folding chair or armchair structure, and in particular, a "director"-type chair, in which a fold-up seat, defined by pivoted elements, crossing one another, is hinged to side frames defining the supporting legs, the armrests and backrest elements of the chair.The folding seat and the side frames include reciprocal connecting means which may snap on and off, to stiffen and hold the chair folded down. The seat and backrest fabrics, moreover, are removably fitted in order to allow the fabrics themselves to be changed.
