Definitions

  • the present invention generally relates to wire spools upon which wire, cord, string, cable or other material can be wound and more particularly relates to three piece wire spools comprising three primary structural components.
  • wire spool One requirement of a wire spool is that a wire manufacturer is able to draw or wind wire onto the spool which requires torque transfer between the barrel and the end flange.
  • a second requirement is that the spool must have sufficient strength to carry the load of the wire and does not collapse or fall apart when transported or when an electrician picks up a fully loaded spool by the end flange.
  • wire spools there are about three conventional and widely used types of wire spools including wood spools, plastic spools and metal spools.
  • Most wood spools are comprised of wood end flanges and a rigid fiberboard barrel that are tied together with tie rod assemblies that run through the barrel and axially retain the wood end flanges of the ends of the barrel.
  • Some wood spools are comprised of five pieces and includes a pair of plastic or metal plugs such as those commercially available from Badger Plug, Inc. to lock the wood end flanges to the barrel.
  • Metal Spools are typically comprised of either three or five structural components and are structurally comprised of formed sheet metal material.
  • Plastic spools commonly comprise of three structural components including a plastic central barrel and a pair of plastic end flanges.
  • plastic spools offer an inexpensive alternative to wood or metal spools.
  • Plastic material is typically much less expensive than metal or wood materials.
  • prior art plastic spools have had one significant problem, namely, that the current process for assembling the plastic end flanges on the ends of the plastic barrel requires MEK (Methyl Ethyl Keytone) which is a hazardous and environmentally unfriendly substance. This substance prepares or softens the plastic material and allows a strong bond to form between the end flanges and the barrel when assembled.
  • MEK Metal Ethyl Keytone
  • Three-piece and five piece metal spools may also have certain advantages such as superior strength and durability, the ability to assembly the metal spool at the location of the wire manufacturer and the fact that product information, decoration and advertising can be easily printed on the outside faces of the flange.
  • assembly difficulties with prior metal spools.
  • complex stamping dies are needed to facilitate assembly of these spools.
  • the center barrel is an expensive component requiring a rolling and seaming operation.
  • the present invention is directed toward an inexpensive wire spool comprising three structural components including two end flanges and a rigid fiberboard barrel.
  • the end flanges have central plug portions that are mechanically locked into the barrel.
  • the central plug portions include teeth which dig into the barrel to substantially permanently secure the end flanges to the barrel such that the wire spool has sufficient strength to allow electricians to pick up a fully loaded wire spool by the end flange and such that the end flanges cannot typically be removed by hand except with the assistance of leverage tools or damaging the spool components.
  • the plug portion also may include elongated axially extending lugs which enhance torque transfer between the barrel and the end flanges.
  • the end flanges are unitary components of molded plastic material (not two separately molded pieces joined together). According to another aspect of the present invention, the end flanges are stamped or formed from sheet metal.
  • FIG. 1 is an isometric illustration of a wire spool containing wire according to a preferred embodiment of the present invention.
  • FIG. 2 is an exploded isometric assembly drawing for the wire spool shown in FIG. 1.
  • FIG. 3 is an enlarged isometric view of one of the end flanges shown in the wire spool of FIG. 2 without the center barrel.
  • FIG. 4 is a cross section of the wire spool shown in FIG. 1, taken about line 4-4 with the center barrel secured.
  • the spool 10 for holding long strands of cable or metal wire 12 thereon.
  • the spool 10 may also be used for other forms of cordage such as string or cord or other material.
  • the spool 10 includes three structural components including a pair of end flanges 14 and a high strength, rigid fiberboard barrel 16.
  • each end flange 14 is molded from relatively strong and rigid plastic material such as high impact polystyrene, polypropylene or ABS.
  • the end flanges 14 could also be metal material and of uniform thickness being stamped and formed from sheet steel.
  • each end flange 14 includes a central plug portion 18 and a disc portion 20 integrally joined together such that the end flange is made as a single component.
  • the plug portion is closely sized to the openings or open ends 22 of barrel 16 to allow sliding insertion of the plug portion 18 into the open ends 22.
  • wire spools typically come in about 6 inch diameters and 10 inch diameter sizes (the diameters of the end flanges), although other sizes are possible.
  • Barrels 16 having a diameter of between about 2 inches to about 4 inches are desirable, with a substantially smaller diameter than that of the end flanges such that the end flanges 14 provide opposed disc shaped retaining walls 24 extending radially beyond the outer radial periphery of the barrel 16 that serves the essential purpose of holding and axially retaining the desired load of wire 12 therebetween.
  • the plug portions 18 are slidably inserted into the open ends 22 with a sufficient pressing force.
  • the plug portions 18 include a projecting cylinder portion 26 that contacts and engages the inner diameter surface of the barrel 16 for radial support.
  • the cylinder portion 26 includes gripping teeth 28 that dig into the fiber material of the barrel 20 for axial retention.
  • Each tooth 28 has a chamfered cam surface 30 on its inside face and a square or perpendicular face 32 on its outer face.
  • the cam surface 30 engages and slides against the inside surface of the barrel 16 during assembly which in turn causes radial expansion of the barrel 16 for clearance and/or the teeth 28 to deflect slightly for clearance radially inward.
  • the plug portion 18 also includes thin elongate lugs 34 at spaced locations.
  • the lugs 34 extend axially are collectively positioned at a diameter just larger than the inside diameter of the barrel 16. When the plug portion is inserted 18, the lugs 34 dig into the fiber material to engage the barrel 16 to enhance torque transfer between the end flanges 14 and the barrel 16.
  • the teeth 28 also provide some torque transfer benefits. Collectively, the teeth 28 and the lugs 34 prevent slippage between the end flanges 14 and the barrel 16 during wire winding operations.
  • the end flange 14 include diametrically opposed central openings 42 coaxial about a predetermined axis 50 of rotation for the spool 10.
  • the spool 10 can be supported for rotation on a support rod (not shown) that extends through the central openings 42.
  • the end flanges 14 also preferably include a starting hole 44 disposed radially inward in the disc portion 20 for receiving the starting strand of wire 12 or cable and a finishing hole 46 disposed radially outward for receiving the cut or terminating strand of wire 12 or cable. If the end flanges 14 are metal, they may also have support ribs (not shown) for increased strength and a safety curl (not shown) at its outer radial periphery for safety purposes.
  • the plug portion 18 of each end flange 14 also includes a pair of 180° degree apart drive holes 48 for receiving the driving mechanism which rotates the spool to wind wire or cable tightly onto the spool.
