Abstract
An improved means to facilitate handling and use of loose coils of electrical wiring consists of a knockdown reel featuring a removable inflatable core, end flanges, a shaft or stub shafts, and adjustable width shaft bearing supports.
Claims9
A knockdown reel for coils of wire comprising:
- a. an inflatable core, said core, by selective inflation thereof, having an adjustable diameter to interfit the bore of wire coils and an adjustable length to match the axial length of wire coils;
- b. a pair of end flanges;
- c. a means to couple the end flanges to the ends of the inflatable core co-axially to form a flanged reel;
- and
- d. a supporting means operatively attached to said flanged reel for support and rotation of the reel thereon and said supporting means being operatively adjustable to accommodate variations in the length of the core and the corresponding distance between the flanges to position the flanges against the sides of the coil;
- whereby wire from the fully supported coils may be successively removed from the coils without binding.
A knockdown reel as claimed in claimed 1 wherein said means to couple the end flanges to the ends of the core comprises an outstanding rib provided on each end of the inflatable core, and the inside face of each flange being provided with a receiving slot for the adjacent rib of the inflatable core so that, when inserted, the ribs will align the core and the flanges co-axially.
A knockdown reel for coils of wire comprising:
- a. an inflatable generally cylindrical core, said core, by selective inflation thereof, having an adjustable diameter to generally conform to the bore of wire coils and an adjustable length to match the axial length of wire coils;
- b. a pair of end flanges, the face of each end flange facing the core having concentric coaxial grooves;
- c. a multiplicity of circumferentially spaced telescopic struts arranged axially around the periphery of the core with each strut, toward the opposed ends thereof, being operatively attached to the core for expansion of the circumferentially spaced struts, against the bore of a wire coil placed on the core between the flanges, upon inflation of the core, the flanges being positioned against the sides of the coil, the struts being positioned at each end by engagement with the grooved flange faces and serving to limit sag of the core due to the weight of the coil;
- and
- d. a supporting means operatively attached to said flanged reel for support and rotation of the reel thereon, said supporting means being operatively adjustable to accommodate variations in the length of the core and the corresponding distance between the flanges to position the flanges against the sides of the coil;
- whereby wire from the fully supported coils may be successively removed from the coils without binding.
