Abstract

A cable spool for networking and cross connect equipment is shown which comprises a telescoping arrangement and is moveable between a retracted and an extended position. In a particular embodiment a static cable spool is provided together with the moveable cable spool and arranged along the same axis. The cable spool is also moveable horizontally.

First claim

The invention claimed is:

1. A telescoping cable spool for attaching to a networking equipment and supporting a plurality of fiber optic cables, the spool comprising:
a hollow fixed part comprising a first end for attachment to a surface adjacent the networking equipment, said fixed part comprising a first elongate slot along a length thereof;
an actuation member dimensioned to fit slideably within said hollow fixed part and comprising a guide pin extending laterally and engaged in said first elongate slot for sliding therein between a rearward position and a forward position; and
a spool housing comprising a pair of cable retaining flanges interconnected by a hollow cable support dimensioned to fit in a telescoping arrangement over said hollow fixed part, an inner surface of said spool housing comprising a first recess intersecting said first elongate slot and engaging an end of said guide pin;
wherein said guide pin links said spool housing to said actuation member such that said spool housing, said actuation member and said guide pin are moveable together relative to said hollow fixed part and along said elongate slot between a first retracted position and a second extended position.

2. The telescoping cable spool of claim 1 , wherein said fixed part is elongate and cylindrical.

3. The telescoping cable spool of claim 1 , wherein said hollow fixed part comprises a second elongate slot along a length thereof opposite said first elongate slot, wherein said inner surface comprises a second recess intersecting said second elongate slot and further wherein said guide pin extends laterally between said first recess and said second recess and is engaged in said second elongate slot for sliding therein between a rearward position and a forward position.

4. The telescoping cable spool of claim 1 , wherein said first elongate slot comprises a rearward end adjacent said first end and further comprising a first angled slot intersecting said first elongate slot at an acute angle at said rearward end, wherein said first recess comprises a length like that of said first angled slot, wherein in said retracted position said first recess is arranged above said first angled slot such that when said guide pin is moved along said first angled slot said guide pin end also moves along said first recess, and further comprising a spring for biasing said guide pin relative to said cable spool such that when in said retracted position said guide pin moves along said first angled slot towards said elongate slot against said a bias of said spring.

5. The telescoping cable spool of claim 1 , wherein said first recess comprises a slot in said cable spool and wherein an end of said guide pin is visible on an outside of said cable spool.

6. A cable spool for attaching to a networking equipment and supporting a plurality of fiber optic cables, the spool comprising:
a static spool comprising a first end secured to the networking equipment, a second end comprising a cable retaining flange and a first cable support interconnecting said first end and said second end; and
an extendable spool comprising an inner cable retaining flange and an outer cable retaining flange interconnected by a second cable support;
wherein said first cable support and said second cable support are arranged about a spool axis and wherein said second extendable spool is moveably secured to said outer end about said spool axis for movement between a retracted position, wherein said inner cable retaining flange is positioned immediately adjacent said outer end, and an extended position, wherein said inner cable retaining flange is away from said outer end.

7. The cable spool of claim 6 , wherein said static spool comprises a fixed part extending away from said outer end along said spool axis, said extendable spool is hollow and arranged about said fixed part such that said extendable spool is moveable along said fixed part in a telescoping arrangement between said retracted position and said extended position.

8. The cable spool of claim 6 , further comprising a mechanism for securing said extendable spool in said retracted position.

9. The cable spool of claim 8 , further comprising an actuator for releasing said mechanism, said actuator comprising a push button positioned at a forward end of said extendable spool and comprising a push axis arranged in parallel to said spool axis.

10. The cable spool of claim 6 , wherein said networking equipment comprises a cable supporting tray positioned adjacent said inner end and said static spool comprises a cable guide interconnecting said first cable support with the tray.
