DESCRIPTION:
BRIEF SUMMARY
The invention is concerned with an anchor clip for fastening one member to another, and more particularly with an anchor clip for securing a spring arrangement for supporting a seat cushion in an article of furniture.
BACKGROUND OF THE PRIOR ART
Anchor clips in general are well known for securing furniture springs to furniture rails forming the framework of an article of furniture. The framework typically includes four elongated furniture rails joined as a rectangle. Corresponding anchor clips are secured by means of staples or depending legs to respective, opposing ones of the rails. The anchor clips typically terminate at one end with a generally curved spring receiving portion. Opposing end portions of a bowed sinuous furniture spring extend between the opposing rails and are secured to the anchor clips within the spring receiving portion. The spring presents a generally inward directed spring force on each of the respective opposing rails via the anchor clips.
As an example, the following U.S. Patents describe various improvements in anchor clips:
One of the problems associated with the types of anchor clips described in the foregoing publications is squeaking. When a person sits down on a sofa chair, force is applied to the engagement between a hook portion on the anchor clip and the engaged portion on the spring. Since both the anchor clip and the spring are metallic, a movement between the two may cause squeaking. The foregoing problem was solved to some extent by incorporating a plastic liner on the interior surface of the hook. However, due to improper installation of the spring and/or clip, and also due to spring irregularities, the liner would sometimes become worn and ineffective, or in the alternative, the liner failed to remain permanently in the hook. In an attempt to overcome this disadvantage, an anchor clip was made completely from a plastic material. However, this plastic clip had the disadvantage of requiring a metal fastener for securing the anchor clip to the rail of the furniture, and also suffered from a lack of strength. The step of securing the plastic anchor clip to the furniture was an added operation, as opposed to anchor clips made of steel.
The present invention is provided to solve these and other problems.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an anchor clip for securing an end of a furniture spring to a furniture rail, as of wood, of a framework of an article of furniture.
It is a further object of the invention to provide a method of manufacturing anchor clips.
A still further object of the invention is to provide an anchor clip provided with a plastic liner permanently secured to a hook portion of the anchor clip.
A related object of the invention is to provide a method of permanently securing a liner in a hook portion of the anchor clip.
According to one aspect of the invention, the anchor clip comprises a base portion, a leg portion, and a reversed curved portion. The base portion is adapted to sit on top of a furniture rail, the reversed curved portion defines a hook for engaging a portion of a spring, and the leg portion is provided with prongs to be driven into the side of the rail.
A first embodiment is concerned with an anchor clip for securing an end of an upholstery spring to a rail of the framework of an article of furniture having a base portion adapted to overlie and be completely supported on the upper surface of a rail of the frame work of an article of furniture. A rail-engaging leg portion is integrally joined to one side of the base portion, the 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 is integrally joined to the other side of the base portion for receiving the end of an upholstery spring and being adapted to be wrapped thereover. The reversed curved portion is supported on the upper or other surface of the rail and the base portion. An embossed ridge extends out of the base portion along a junction line between t
