Abstract
An anchor clip for holding an edge of a cushion-supporting upholstery spring in position on a wooden rail of an article of furniture, the clip having a base portion, a leg portion, and reversed curved portion, the reversed curved portion defining a hook which is inwardly lined with a plastic liner. Lateral edges of the hook are flared outwardly to relieve pressures at both sides of the liner. The free end of the hook is folded-over to entrap one end of the liner and subsequently staked. In another embodiment, the hook, at the acme of the curvature, is provided with a cut-out and flared area on each lateral side of the hood for relieving pressure on the liner.
Claims11
An anchor clip for securing an end of an upholstery spring to a rail of the framework of an article of furniture, comprising:
- a base portion adapted to overlie and to be completely supported on a surface of a rail of an article of furniture;
- a rail-engaging leg portion integrally formed on a first end of the base portion, said leg portion having integral anchoring means adapted to be embedded in the rail for securing the anchor clip on the rail;
- a reversed curved portion integrally joined to a second end of the base portion for receiving an upholstery spring and being adapted to be wrapped thereover, said reversed curved portion being supported by fixation of the clip on a surface of said rail, the reversed curved portion facing said rail and having a free end with an edge;
- at least one embossed ridge extending out of said base portion along a junction line between said base portion and said reversed curved portion;
- and
- a liner attached to said curved portion between said free edge and said embossed ridge, wherein said free edge is folded downwardly and over unto itself in order to engage and prevent said liner from displacing out of said clip at said free end.
An anchor clip for securing an end of an upholstery spring to a rail of the framework of an article of furniture, comprising:
- a base portion adapted to overlie and to be completely supported on a surface of a rail of an article of furniture;
- a rail-engaging leg portion integrally formed on a first end of the base portion, said leg portion having integral anchoring means adapted to be embedded in the rail for securing the anchor clip on the rail;
- a reversed curved portion integrally joined to a second end of the base portion for receiving an upholstery spring and being adapted to be wrapped thereover, said reversed curved portion being supported by fixation of the clip on a surface of said rail, said curved portion facing said rail and having a free end with an edge and a pair of lateral edge portions having cut-outs in both of said lateral edge portions,
- at least one embossed ridge extending out of said base portion along a junction line between said base portion and said reversed curved portion;
- a liner attached to said curved portion between said free edge and said embossed ridge, wherein said free edge is folded-over unto itself in order to prevent said liner from displacing out of said clip at said free end and wherein the liner extends beyond said lateral edge portions in a region of contact with the spring.
A method of preparing a series of anchor clips interconnected together by integrally connected bands, comprising the steps of:
- feeding a steel band;
- applying an adhesive along one edge of the band;
- affixing with the adhesive a plastic trip to the band;
- slitting the band to form separate clip section;
- folding and staking an end of each of the clip sections;
- punching separating holes and indexing holes;
- punching leg holes;
- forming strengthening ridges, legs, and the hook and base portion;
- and
- forming flared areas at the lateral edge of the hook to relieve potential high pressure points.
