Abstract

A storage spool adapted to have excess optical fiber or wired lengths wound thereon consists of a cylinder having a curved outer surface on which the fibers are to be wound. A mounting arm extends from a separating wall portion on the curved surface and has a mounting latch member on its distal end. The arm has an arcuate fiber guide portion for guiding the fibers onto the curved surface, and retaining means are provided for maintaining the fibers in position on the curved surface of the cylinder.

Claims

1. A storage member for storing optical fibers and the like thereon comprising:

a substantially cylindrical member having an outer curved surface for winding the fibers thereon and first and second ends;

a mounting arm extending from said cylindrical member and having proximal and distal ends; and

mounting means on said distal end for mounting said storage member to a coupler containing plate member.

2. A storage member as claimed in claim 1 and further comprising means on said cylindrical member at said first and second ends thereof for confining the fiber wound on said cylindrical member to the space between said first and second ends.

3. A storage member as claimed in claim 1 and further comprising means for maintaining separation of at least some of the fibers to be wound on said cylindrical member.

4. A storage member as claimed in claim 3 wherein said means for maintaining separation has means thereon for minimizing loops of slack fiber.

5. A storage member as claimed in claim 1 wherein said means for maintaining separation comprises at least one wall member extending radially from said curved surface.

8. A storage member as claimed in claim 1 wherein said wall members extend radially from said curved surface.

9. A storage member as claimed in claim 8 wherein said wall member is centrally located between said first and second ends.

10. A storage member as claimed in claim 8 and further comprising fiber guide means on said wall member extending on either side thereof.

11. A storage member as claimed in claim 10 wherein said guide means has an arcuate configuration.

13. A storage member as claimed in claim 1 wherein said member is made of a plastic material.

14. A storage member as claimed in claim 13 wherein said plastic material is a polycarbonate material.

6. A storage member for storing optical fibers and the like thereon comprising:

a substantially cylindrical member having an outer curved surface for winding the fibers thereon and first and second ends;

a mounting arm extending from said cylindrical member and having proximal and distal ends;

mounting means on said distal end for mounting said storage member to a coupler containing plate member; and

said mounting arm including means for dividing said curved surface into first and second fiber storage areas.

7. A storage member as claimed in claim 6 wherein said means for dividing comprises a wall member at the proximal end of said mounting arm.

12. A storage member for storing optical fibers and the like thereon comprising:

a substantially cylindrical member having an outer curved surface having a radius of curvature of at least three-quarters of an inch (3/4") for winding the fibers thereon and first and second ends;

a mounting arm extending from said cylindrical member and having proximal and distal ends; and

mounting means on said distal end for mounting said storage member to a coupler containing plate member.

15. For use with a wall plate and outlet assembly wherein the wall plate has front and rear surfaces and at least one optical fiber coupler therein for receiving optical fiber connectors, a fiber storage spool comprising:

a cylindrical member having a longitudinal axis and having first and second ends and a curved outer surface;

a mounting arm extending from said cylindrical member and having a proximal end adjacent said cylindrical member and a distal end;

mounting means on said distal end for mounting said storage spool to the rear surface of the wall plate;

said proximal end of said mounting arm forming at least two fiber storage areas on said curved surface of said cylindrical member;

a fiber guide member on said mounting arm adjacent said proximal end; and

retaining means on said first and second ends of said cylindrical member for maintaining fiber wound on said cylindrical member in place thereon.

16. A fiber storage spool as claimed in claim 15 wherein said retaining means comprises a plurality of radially extending spaced tab members.

17. A fiber storage spool as claimed in claim 15 wherein said fiber guide member comprises an arcuate member extending from either side of said mounting arm and spaced from said curved surface.

18. A fiber storage spool as claimed in claim 15 and further comprising a separating wall extending radially from said curved surface, said wall having locating and retaining fingers extending outwardly therefrom substantially parallel to the longitudinal axis of said cylindrical member.

19. A fiber storage spool as claimed in claim 15 wherein said mounting means comprises spring latch mounting, and locking member adapted to fit within a mating opening in the rear surface of the wall plate.

20. A fiber storage spool as claimed in claim 15 wherein said spool is made of a plastic material.

21. A fiber storage spool as claimed in claim 20 wherein said plastic material is polycarbonate ABS blend.

22. A flush mounted wall plate and storage assembly comprising, in combination:

a wall plate member having a movable portion for receiving optical fiber connector and the like, said wall plate member having a rear surface;

a storage spool comprising a substantially cylindrical member having a curved outer surface for winding the fibers thereon and first and second ends;

a mounting member extending between said rear surface of said wall plate member and said storage spool, said mounting member having a first end adjacent said rear surface of said wall plate and a second end adjacent said curved outer surface.

23. The wall plate and storage assembly as claimed in claim 22 wherein said first end of said mounting member has means for affixing said mounting member to said wall plate.
