Definitions
- This invention relates generally to clip assemblies for use in the manufacture of furniture and, more particularly, for holding sinuous springs in position in furniture.
- Such a clinching tool typically includes a J-shaped jaw into which the leading clip of a stack of clips is indexed.
- the clinching tool has a blade which shears off the first clip from a stack of clips placed inside the clinching tool.
- U.S. Patent No. 2,574,81 1 shows such a clinching tool.
- Clips must be interconnected to each other in a flexible manner so that the stack of clips can be wound into the clinching tool.
- the clips must also be interconnected with sufficient strength so that they are able to withstand high tensile forces associated with winding and unwinding of the stack of clips upon a spool in the clinching machine. Accidental breakage of the connector connecting adjacent clips would be detrimental to the operation of the clinching machine.
- U.S. Patent No. 5,303,821 discloses deforming the side edges of the arcuate crown portion of each clip inwardly so as to crimp the plastic connectors inside the grooves or slots on the arcuate top portions of the sheet metal U-shaped clips.
- U.S. Patent Nos. 5,564,564; 5,682,994 and 5,878,880 each disclose a U-shaped clip having tabs extending upwardly from slots formed in the arcuate crown portion of the clip. After connectors are placed inside the slots of a plurality of aligned clips, a roller or rollers pass over the arcuate crown portions of the clips to push down the tabs of each clip, thereby securing the connectors inside the slots.
- U.S. Patent No. 5,878,880 discloses a clip made of sheet metal having a U-shaped hook portion inside which is secured a sheet of cushioning material, such as plastic. When a wire is placed inside the hook portion, the cushioning material prevents wire-on-wire noise, such as squeaking.
- U.S. Patent No. 5,833,064 discloses another such clip having a plastic liner to prevent metal-on-metal squeaking or 'noise". Over time, these plastic liners may wear out or move/shift.
- U.S. Patent Nos. 5,878,880 and 5,833,064 disclose U-shaped clips which may be connected to identical clips in a string and which have prongs or tacks inherently formed from the sheet metal, the prongs being bent downwardly and adapted to be inserted into wooden rails of furniture frames. These prongs or tacks have a smooth surface which may not hold the clip inside wooden rails of furniture frames as securely as desired.
- This invention comprises a clip assembly for securing an end portion of a sinuous spring to a wooden rail.
- the clip assembly comprises two components: a plastic clip and a metal fastener, including at least two tacks extending downwardly from a portion of the metal fastener wherein each of the tacks passes through the plastic clip.
- the tacks may be driven through, molded into or passed through holes or openings in the plastic clip.
- the metal fastener is a unitary member, the tacks of the metal fastener being formed from the metal material of the fastener and extending outwardly from the remainder of the metal fastener.
- each metal fastener or second piece of each clip assembly may have two tacks. In other embodiments, each metal fastener or second piece of each clip assembly may have four tacks.
- the clip assembly comprises a non-metallic clip having a U-shaped hook portion adapted to receive and retain a portion of a spring and a metal fastener, including at least two tacks extending outwardly from a planar portion of the fastener wherein each of the tacks passes through the non-metallic clip.
- the plastic clip may lack openings, in which case the tacks of the metal fastener would be driven through the material of the non-metallic clip.
- the clip assembly comprises a first non-metallic piece having openings therethrough and a second metal piece having projections extending through the openings of the first piece, the projections being adapted to be secured into a wooden rail.

- the connectors 38 provide flexibility in the collated string 56h of clip assemblies 18h, which is needed when the string 56h is bent and rolled into a spool for insertion into a clipping tool.
- the connectors 38 have the required tensile strength to withstand pulling and twisting forces without breaking. Also, when a last clip assembly is cut off from the string 56h, there are no sharp or jagged barbs left over to injure workers or tear fabric covering the clipped wires.
- the connectors 38 When used in a clipping tool, the connectors 38 may be broken between adjacent clip assemblies 18h in the collated string 56h of clip assemblies 18h, leaving portions 58 of the connectors 38 with the clip assembly 18h secured to the frame 12b.
- Fig. 42A illustrates one such clip assembly 18h, each clip assembly 18h having portions 58 of the connectors 38 still with the clip assembly 18h when the clip assembly 18h is secured to one of the side walls 14b of frame 12b.
- Fig. 43 A illustrates four clip assemblies 18h aligned in a string 57h of aligned collated clip assemblies.
- the string 57h of aligned collated clip assemblies 18h may be made of any number of clip assemblies 18h connected together using connectors 39.
- connectors 39 made from the material of the second pieces 22 of clip assemblies 18h, extend between the second pieces 22h of adjacent clip assemblies 18h.
- Connectors 39 may be broken where desired in a clipping tool. Instead of connectors 38, connectors 39 may be used in any embodiment shown or described herein.
- FIGs. 46A-46E shows another variation of clip assembly 18i. As best shown in Fig. 46A, each clip assembly 18i has a first piece 22i identical to the first piece 22g of clip assembly 18g without the grooves. Each clip assembly 18i has a pair of fasteners 25.
- each fastener 25 may be unthreaded like the tacks 42b shown in Fig. 15, for example.
- the pieces 22i, 25 are molded together into a unitary member and secured to one of the side walls 14 of the generally rectangular furniture frame 12.
- the first piece 22i of clip assembly 18i comprises a
- the first piece 22i further comprises a generally planar body portion 28i which includes a ledge 30i extending from one side edge 32i to the opposed side edge 32i of the body portion 28i of the first piece 22i of the clip assembly 18i.
- the ledge 30i of the body portion 28i holds or retains the end portion 21 of the sinuous spring 20 in a receptacle 3 l i, illustrated in Fig. 46A.
- the first piece 22i of clip assembly 18i further comprises a generally planar flange portion 34i extending outwardly from the end of the body portion 28i opposite the U-shaped hook portion 26i in a direction generally orthogonal or perpendicular to the body portion 28i.
- the heads 29 of the fasteners 25 of clip assembly 18i are encased by or surrounded by the flange portion 34i of the first piece 22i of clip assembly 18i during a molding process.
- these clip assemblies 18i may be stored and transported in a package 60, as shown in Fig. 9 or any other like container or package.
- FIGs. 47A-47C shows another variation of clip assembly 18 j .
- each clip assembly 18 j has a first piece 22j identical to the first piece 22h of clip assembly 18h without the grooves.
- Each clip assembly 18 j has four fasteners 25. Although the fasteners 25 are illustrated as being threaded members, each fastener 25 may be unthreaded like the tacks 42b shown in Fig. 15, for example.
- the pieces 22j, 25 are molded together into a unitary member and secured to one of the side walls 14 of the generally rectangular furniture frame 12.
- the first piece 22j of clip assembly 18 j comprises a
- the first piece 22j further comprises a generally planar body portion 28j which includes a ledge 30j extending from one side edge 32j to the opposed side edge 32j of the body portion 28j of the first piece 22j of the clip assembly 18 j .
- the ledge 30j of the body portion 28j holds or retains the end portion 21 of the sinuous spring 20 in a receptacle 3 lj, illustrated in Fig. 47A. As best shown in Fig.
- the heads 29 of the fasteners 25 of clip assembly 18 j are encased by or surrounded by the body portion 28j of the first piece 22j of clip assembly 18j during a molding process. Rather than being secured together with connectors, these clip assemblies 18 j may be stored and transported in a package 60, as shown in Fig. 9 or any other like container or package.
- the tacks are shown having a certain cross-sectional configuration, they may be other sizes or shapes.
- the openings in the non-metallic pieces of the clip assemblies may be any desired shapes or sizes.
