Cable roller, system and/or method for extending and/or retracting a coiled cable
A cable roller, a system and/or a method extend and/or retract a coiled cable. The cable roller, the system and/or the method secure an article to a fixture while allowing manipulation, testing and/or maneuvering of the article with respect to the fixture. A drum attaches to the fixture. The drum has a sleeve that rotates freely with respect to the central axis of the drum. A spring action of the coiled cable rotates the sleeve to extend and/or to retract the coiled cable from an underside of the fixture.
1. A cable roller for retracting a coiled cable into a fixture wherein the fixture has a top surface and a bottom surface wherein the bottom surface is positioned opposite to the top surface, the cable roller comprising:
a drum having a central axis, a length defined between a first end and a second end, a thickness defined between an internal diameter and an external diameter, a junction ring defined at an external circumference of the drum at a point between the first end of the drum and the second end of the drum, and a junction point along the junction ring;
a mounting bracket having a wall defined by a top end and a bottom end wherein the wall is affixed to the junction point and further wherein the coiled cable encircles the drum and intersects the junction ring and further wherein the wall prevents overlap of the coiled cable;
a first end cap having a length defined between a first end and a second end wherein the first end cap has a flange that extends radially from the first end of the first end cap wherein the second end of the first end cap has an external diameter that is less than the internal diameter of the drum wherein the second end of the first end cap inserts into the first end of the drum; and
a sleeve around the drum between the first end of the drum and the junction point wherein the sleeve has an internal diameter that is greater than the external diameter of the drum wherein the sleeve rotates around the drum.
2. A cable roller for retracting a coiled cable into a fixture wherein the fixture has a top surface and a bottom surface wherein the bottom surface is positioned opposite to the top surface, the cable roller comprising:
a drum having a central axis, a length defined between a first end and a second end, a thickness defined between an internal diameter and an external diameter, a junction ring defined at an external circumference of the drum at a point between the first end of the drum and the second end of the drum, and a junction point along the junction ring;
a mounting bracket having a wall defined by a top end and a bottom end wherein the wall is affixed to the junction point and further wherein the coiled cable encircles the drum and intersects the junction ring and further wherein the wall prevents overlap of the coiled cable;
a first end cap having a length defined between a first end and a second end wherein the first end cap has a flange that extends radially from the first end of the first end cap wherein the second end of the first end cap has an external diameter that is less than the internal diameter of the drum wherein the second end of the first end cap inserts into the first end of the drum; and
a sleeve around the drum between the second end of the drum and the junction point wherein the sleeve has an internal diameter that is greater than the external diameter of the drum wherein the sleeve rotates around the drum.
3. The cable roller of claim 1 wherein the drum has a low friction surface.
4. The cable roller of claim 1 further comprising:
a second end cap that inserts into the second end of the drum.
5. The cable roller of claim 1 further comprising:
a slot in the mounting bracket wherein the slot is sized to seat the coiled cable.
6. The cable roller of claim 1 further comprising:
an aperture in the mounting bracket wherein the aperture forms a passage for the coiled cable.
7. The cable roller of claim 1 further comprising:
means for attaching the mounting bracket to the fixture.
8. The cable roller of claim 1 further comprising:
a post assembly that attaches to the mounting bracket wherein the post assembly is position adjacent to the fixture and further wherein the mounting bracket is positioned adjacent to the fixture.
9. The cable roller of claim 8 further comprising:
a connector that attaches the post assembly to the mounting bracket.
10. The cable roller of claim 1 further comprising:
a rib extending from the flange wherein the rib forms a grip to remove the first end cap from the drum.
11. A method for securing an article to a fixture, the method comprising the steps of:
providing a coiled sensor cable and a cable roller wherein the coiled sensor cable has a first end and a second end wherein the cable roller has a fixed drum;
attaching a mounting bracket to the fixed drum;
attaching the cable roller to the fixture with the mounting bracket;
threading the first end of the coiled sensor cable through the fixture and around the fixed drum wherein the cable encircles the fixed drum on each side of the mounting bracket without overlap of the cable;
anchoring the coiled sensor cable to the mounting bracket at a point between the first end of the coiled sensor cable and the second end of the coiled sensor cable;
attaching the first end of the coiled sensor cable to the fixture; and
attaching the second end of the coiled sensor cable to the article.
12. The method of claim 11 further comprising the step of:
positioning a rotatable sleeve between the fixed drum and the coiled sensor cable.
13. The method of claim 11 further comprising the step of:
attaching an end cap to the fixed drum.
14. The cable roller of claim 2 further comprising:
a second end cap that inserts into the second end of the drum.
