Abstract

A ribbon cable storage spool, tray and method of use. The spool comprising a center post and a plurality of radially extending top and bottom fins. The spool may also comprise a guide wall, a ribbon retention tab, a channel wall defining a channel and a ledge, and an oblong shape. The tray comprising a bottom plate and a sidewall which act together to define a spool chamber for receiving the spool. The bottom plate may also define holes such that the bottom fins of the spool are coplanar with the bottom plate when the spool is placed in the tray. The bottom plate may also include a column to be received by the channel of the spool. The channel and column may include a tongue and groove arrangement for preventing rotation of the spool relative to the tray. The column may also include a flexible clip for retaining the spool in the tray. A method for winding a length of cable onto a spool without twisting the wires including the steps of crossing two lengths of the loop, first-flipping the spool, second-flipping the spool, and repeating these steps until the length of the loop is wound around the spool.

Claims

1. A storage spool for storing telecommunications cable, the spool comprising:

a center post having a top end and a bottom end and being characterized by a center axis, and defining a cylindrical surface;

a plurality of radially extending bottom fins extending in a plane perpendicular to the center axis, the bottom fins extending from the bottom end of the center post, each bottom fin having an outermost edge furthest away from the center post;

a plurality of radially extending top fins extending in a plane perpendicular to the center axis, the top fins extending from the top end of the center post, each top fin having an outermost edge furthest away from the center post;

wherein the outermost edges of the top and bottom fins define an outer profile of the storage spool, wherein the outer profile is oblong.

2. The storage spool according to claim 1, wherein the top fins and the bottom fin axially opposes a fins are sized, shaped, and spaced around the center post so that no bottom top fin.

3. The storage spool according to claim 1, further comprising at least one guide wall attached to a top or bottom fin, the guide wall extending from the outermost edge of the respective fin and being oriented perpendicular to the respective fin and parallel to the center axis.

4. The storage spool according to claim 1, further comprising a retention tab extending from and perpendicular to a bottom fin, the retention tab being spaced from the center post a distance approximately equal to the thickness of the cable to be stored.

5. The storage spool according to claim 1, further comprising a channel wall that defines a channel inside the center post.

6. The storage spool according to claim 5, wherein the channel wall defines a ledge perpendicular to the center axis.

7. A storage spool for storing fiber cable, the spool comprising;

a center post having a first end and a second end and being characterized by a center axis, and a channel wall that defines a channel inside the center post, the center post defining a cylindrical surface;

a plurality of radially extending second-end fins extending in a plane perpendicular to the center axis, the second-end fins extending from the second end of the center post, each second-end fin having an outermost edge furthest away from the center post;

a plurality of radially extending first-end fins extending in a plane perpendicular to the center axis, the first-end fins extending from the first end of the center post, each first-end fin having an outermost edge furthest away from the center post;

wherein the outermost edges of the first-end and second-end fins define an oblong outer profile of the storage spool;

a guide wall attached to at least one first-end or second-end fin, the guide wall extending from the outermost edge of the attached fin and being oriented perpendicular to the attached fin and parallel to the center axis.

8. A cable storage device comprising:

(a) a spool including;

(i) a center post having a top end and a bottom end and being characterized by a center axis;

(ii) a plurality of radially extending bottom fins extending in a plane perpendicular to the center axis, the bottom fins extending from the bottom end of the center post, each bottom fin having an outermost edge furthest away from the center post;

(iii) a plurality of radially extending top fins extending in a plane perpendicular to the center axis, the top fins extending from the top end of the center post, each top fin having an outermost edge furthest away from the center post;

(b) a tray including;

(i) a bottom plate, the bottom plate defining holes shaped to allow the bottom fins of the spool to be coplanar with the bottom plate when the spool is placed in the tray;

(ii) a sidewall perpendicular to the bottom plate and extending from the bottom plate to define a spool chamber, the spool being received in the spool chamber, the sidewall defining an entry port and an exit port for allowing entry and exit of the cable to be stored.

9. The storage device according to claim 8, wherein the spool further comprises a channel wall that defines a channel inside the center post;

and wherein the tray further comprises a column extending from the bottom plate, the column received within the channel of the spool.

10. The storage device according to claim 9, wherein the channel wall defines a ledge perpendicular to the center axis;

and wherein the column of the tray comprises a flexible clip, the flexible clip having a push tab and a protruding edge, the protruding edge being configured to fit into the ledge of the channel wall of the spool, wherein the spool may be removed from the column only when the push tab is depressed.

11. The storage device according to any of claims 8-10, wherein the tray further comprises hinge tabs for rotatably mounting the tray to a storage tray mount.

12. A tray for storing a spool of telecommunications cable, the spool having a center post and outwardly extending bottom fins, the tray comprising:

a bottom plate, the bottom plate defining holes shaped to allow the bottom fins of the spool to be coplanar with the bottom plate when the spool is placed in the tray;

a side wall perpendicular to the bottom plate and extending from of the bottom plate to define a spool chamber for receiving the spool, the sidewall defining an entry port and an exit port for allowing entry and exit of the cable to be stored.

13. A tray according to claim 12, further comprising hinge tabs for rotatably mounting the tray to a storage tray mount.
