Abstract

A piece of furniture includes a rectangular frame for supporting a plurality of sinuous springs. A plurality of clip assemblies are secured to opposed side walls of frame. Each clip assembly comprises at least two metal fasteners, each having a generally planar head and a shank for insertion into the frame. The generally planar head of each metal fastener is encased by plastic of a non-metallic piece. The non-metallic piece has a hook to secure one end of a sinuous wire. Connectors may be formed with the plastic or non-metallic pieces to join multiple clip assemblies.

First claim

We claim:

1. A clip assembly for securing an end portion of a sinuous spring to a wooden rail, said clip assembly comprising:
a plastic piece comprising a generally planar body portion, a U-shaped hook portion extending outwardly from one end of the body portion, the hook portion being adapted to receive and retain the end portion of the sinuous spring, and a generally planar flange portion extending outwardly from the other end of the body portion in a direction generally perpendicular to the body portion; and
at least two metal fasteners, each metal fastener having a generally planar head and a shank,
wherein the metal fasteners and plastic piece are molded together into a unitary member, the head of each metal fastener being encased by the flange portion of the plastic piece, the shank of the metal fastener extending through the plastic piece and being adapted to extend into the wooden rail.

2. The clip assembly of claim 1 , wherein the shank of at least one metal fastener is ribbed.

3. The clip assembly of claim 1 , wherein the shank of each metal fastener is ribbed.

4. The clip assembly of claim 1 , wherein the shank of at least one metal fastener is serrated.

5. The clip assembly of claim 1 , wherein the shank of at least one metal fastener is generally planar.

6. The clip assembly of claim 1 , wherein the clip assembly has two metal fasteners.

7. The clip assembly of claim 1 , wherein the shank of at least one of the metal fasteners is creased.

8. The clip assembly of claim 1 , wherein the head of each metal fastener is circular.

9. The clip assembly of claim 1 , wherein the generally planar body portion of the plastic piece has a ledge extending from one side edge to the opposed side edge of the plastic piece.

10. A clip assembly for securing an end portion of a sinuous spring to a wooden rail, said clip assembly comprising:
a non-metallic piece comprising a generally planar body portion, a U-shaped hook portion extending outwardly from one end of the body portion and a generally planar flange portion extending outwardly from the other end of the body portion in a direction generally perpendicular to the body portion, wherein the generally planar body portion of the non-metallic piece has a ledge extending from one side edge to the opposed side edge of the non-metallic piece, the hook portion and ledge being adapted to receive and retain the end portion of the sinuous spring; and
at least two metal fasteners, each metal fastener having a generally planar head and a shank;
wherein the metal fastener and non-metallic piece are molded together into a unitary member, the head of each metal fastener being encased by the flange portion of the non-metallic piece, the shank of the metal fastener being adapted to extend into the wooden rail.

11. The clip assembly of claim 10 , wherein the head of each metal fastener is circular.

12. The clip assembly of claim 10 , wherein the shank of at least one metal fastener is ribbed.

13. The clip assembly of claim 10 , wherein at least one of the shanks of the metal fastener is serrated.

14. The clip assembly of claim 10 , wherein the shank of at least one metal fastener has a uniform thickness.

15. The clip assembly of claim 10 , wherein the shank of at least one of the metal fasteners is creased.

16. The clip assembly of claim 10 , wherein the clip assembly has two metal fasteners.

17. A clip assembly for securing an end portion of a sinuous spring to a wooden rail, said clip assembly comprising:
a non-metallic piece comprising a generally planar body portion, a U-shaped hook portion extending outwardly from one end of the body portion and a generally planar flange portion extending outwardly from the other end of the body portion in a direction generally perpendicular to the body portion, wherein the generally planar body portion of the non-metallic piece has a ledge extending from one side edge to the opposed side edge of the plastic piece, the hook portion and ledge being adapted to receive and retain the end portion of the sinuous spring; and
two spaced metal fasteners, each metal fastener having a generally planar head and a shank,
wherein the metal fasteners and non-metallic piece are molded together into a unitary member, the head of each metal fastener being encased by the flange portion of the non-metallic piece, the shanks of the metal fasteners extending through the flange portion of the non-metallic piece and being adapted to extend into the wooden rail.

18. The clip assembly of claim 17 wherein the head of at least one metal fastener is circular.

19. The clip assembly of claim 17 , wherein the clip assembly has two metal fasteners.

20. The clip assembly of claim 17 , wherein the shank of at least one metal fastener is ribbed.

21. The clip assembly of claim 17 , wherein at least one of the shanks of the metal fastener is serrated.

22. The clip assembly of claim 17 , wherein the shank of at least one metal fastener has a uniform thickness.

23. The clip assembly of claim 17 , wherein the shank of at least one of the metal fasteners is creased.
