Abstract

Abstract A device for use in assisting a person in unwinding or re-winding coil wire includes a base adapted to rest on a horizontal surface and a coil holder rotatably mounted on the base and sized to accommodate the coil wire. The coil holder has a disc having a top surface and a bottom surface. A wire guide projects upward from the top surface of the coil holder and an axle having a circular flange projects downward from a boss on the bottom surface. The base includes a mounting hole into which the axle of the disc is inserted until the boss rests upon the base. The base also includes a barrier which is generally cylindrically shape and which is situated so as to prevent the wire from becoming caught between the disc and the base as it is being unwound or rewound. To unwind coil wire, a user places the coil on the top surface of the coil holder in such a way as to encircle the wire guide. The user then puts an end of the wire through a hole in the barrier and pulls on the end of wire causing the disc to rotate and the wire to become unwound. To re-wind the unwound wire, the user simply rotates the disc in the opposite direction. As the disc rotates, the wire re-wraps around the wire guide.

Claim 3
Dependent Claim 168 words
(a) a base adapted to rest on a horizontal surface, said base having; (i) a disc hole, circular in shape, having a diameter d 1 , (ii) a cylindrical wall, disposed concentrically about said disc hole, said cylindrical wall having a diameter d 2 wherein d 2 is several times greater than d 1 ; and (b) a coil holder rotatably mounted on said base, said coil holder having: (i) a disc sized and shaped to accommodate the coiled wire, said disc having a top surface, a bottom surface, and a diameter d 3 wherein d 3 is greater than d 1 but is less than d 2 by no more than 1/4 inch. (ii) a boss centrally disposed on said bottom surface of said disc for elevating said disc relative to said base, (iii) a cylindrical axle for insertion into said disc hole. said axle being centrally disposed on said boss and having a diameter d 4 wherein d 4 is slightly smaller than d 1 .
Claim 4
Dependent Claim 168 words
(a) a base adapted to rest on a horizontal surface, said base having; (i) a disc hole, circular in shape, having a diameter d 1 , (ii) a cylindrical wall, disposed concentrically about said disc hole, said cylindrical wall having a diameter d 2 wherein d 2 is several times greater than d 1 ; and (b) a coil holder rotatably mounted on said base, said coil holder having: (i) a disc sized and shaped to accommodate the coiled wire, said disc having a top surface, a bottom surface, and a diameter d 3 wherein d 3 is greater than d 1 but is less than d 2 by no more than 1/4 inch. (ii) a boss centrally disposed on said bottom surface of said disc for elevating said disc relative to said base, (iii) a cylindrical axle for insertion into said disc hole. said axle being centrally disposed on said boss and having a diameter d 4 wherein d 4 is slightly smaller than d 1 .
Claim 5
Dependent Claim 66 words
The device as recited in claim 1 and wherein said coil holder has a square hole centrally disposed on said top surface of said disc and wherein said device further comprises a crank rewinder having a base shaped and sized to fit in said square hole for the purpose of causing the rotation of said disc in the direction causing the re-winding of the coiled wire.
Claim 6
Dependent Claim 75 words
The device as recited in claim 1 and wherein said coil holder has a second boss centrally disposed on said top surface of said disc, said second boss having a square hole centrally located and wherein said device further comprises a crank re-winder having a base shaped and sized to fit in said square hole for the purpose of causing the rotation of said disc in the direction causing the re-winding of the coiled wire.
Claim 7
Independent Claim 38 words
The device as recited in claims 2 or 3, further comprising a rubber gripping strip affixed to the bottom of said base for the purpose of preventing the movement of said base when said device is in use.
