  • Patent number: 4280548
    Abstract: A support for furniture, such as outdoor furniture, has a support frame and stretched thereon is a net or lattice-like arrangement of flat web strips of plastics material; where they cross one another the strips are bonded together by means of thin planar enveloping members. The webs extend between and are secured to opposite sides of the frame, and to each end of each web a securing member is attached; each web is secured to an associated side of the frame by looping its end around the side and fastening the end by means of slipping the securing member onto the strip itself in the vicinity of the frame. Several forms of securing member are disclosed, and in each case the member is slotted or U-shaped enabling the member to be slipped transversely onto the strip. Each member has means to prevent the securing member inadvertently slipping transversely off the strip.

  • Patent number: 4047824
    Abstract: A connection between a metal wire hook and a cord of synthetic fiber material particularly suitable for connecting nets of crossing cords into frames for chairs, sofas, beds and similar furniture. The metal wire has a bent portion with a free end. The bent portion of the metal wire spans an angle in excess of 180.degree. and has a pair of shanks which define a clearance space therebetween. The cord extends through this clearance space and the portion of the cord in the clearance space is squeezed and has therefore a reduced cross-section. The hooked portion of the metal wire and the squeezed portion of the cord are preferably cast into a sheathing of thermoplastic material.
