Abstract

An optical fiber cable management panel is provided with slidable drawers and structure within the drawers for cable management and/or connection to other devices. Tray inserts drop into the drawers to provide the appropriate management and connection devices. A movable take-up mechanism manages the cable entering and exiting the drawers at side openings. Stackable pivoting storage trays on the tray insert include a detent arrangement for holding each tray in a pivoted access position. The tray inserts further include a front key, and a back tab mounting arrangement for mounting the tray inserts to the drawers, and side radius limiters including notches for extending over raised portions of the drawer. The take-up mechanism includes a U-shaped trough section and cable retention tabs. A control mechanism is provided for controlling movement of the take-up mechanism relative to the drawer.

First claim

What is claimed is:

1. A cable management panel comprising:
a chassis;
a drawer slidably mounted within the chassis, the drawer slidable between a first position with the drawer fully inserted within the chassis and a second position with the drawer extended from the interior of the chassis;
an access location allowing entry of optical fiber cable into a side of the chassis and the drawer; and
a cable take-up mechanism including a radius limiter slidably mounted relative to the drawer and movable via a control mechanism that includes a rotating member having teeth that engage a gear rack on at least one of the chassis and the drawer from a first position relative to the chassis toward a second position relative to the chassis which is forward of the first position as the drawer is moved from the first position to the second position, wherein movement of the drawer is synchronized at all times with the movement of the cable take-up mechanism relative to the chassis such that the drawer and the cable take-up mechanism are configured to move simultaneously in the same direction relative to the chassis, wherein the cable take-up mechanism is configured to move with respect to the drawer in a direction that is parallel to the movement of the drawer relative to the chassis, the synchronized movement being controlled by the control mechanism.

2. A cable management panel of claim 1 , wherein the drawer includes a front key and a rear slot, and further comprising a drop-in plate including a notch along a front edge, and a tab along a rear edge, the notch engagable with the key of the drawer, the tab engagable with the slot of the drawer.

3. The cable management panel of claim 1 , wherein the drawer includes a base and raised side ledges on opposite sides of the drawer, and further including a drop-in plate including a base and two side edges which are positioned adjacent to the side ledges of the drawer, the plate including two radius limiters, each radius limiter having a portion extending beyond the respective side edges of the base of the plate, each radius limiter having a notch along a lower edge, the notch extending from each respective side edge of the base of the plate to the side ledge of the drawer.

4. The cable management panel of claim 3 , wherein the drawer includes a front key and a rear slot, and further comprising a drop-in plate including a notch along a front edge, and a tab along a rear edge, the notch engagable with the key of the drawer, the tab engagable with the slot of the drawer.

5. The cable management panel of claim 1 , further comprising a storage tray mount on the drawer, the storage tray mount having a plurality of pairs of opposed, staggered mounting locations, and a plurality of storage trays, each storage tray rotatably mounted to the storage tray mount at one of the staggered mounting locations, wherein one of the trays and the tray mount includes a post and the other includes a hole for receiving the post so as to rotatably mount each tray to the tray mount at each mounting location, and wherein one of the trays and the tray mount includes a projection extending parallel to a rotation axis of the tray, and the other includes a notch wherein the projection is received in the notch when each tray is pivoted vertically upwardly from a first horizontal position to a second pivoted position at an angle to the horizontal.

6. The cable management panel of claim 1 , wherein the access location is a first access location, and wherein two take-up mechanisms are provided, one adjacent to each side of the drawer, a second access location provided opposite the side with the first access location.

7. The cable management panel of claim 1 , wherein the gear rack is provided on the chassis.

8. The cable management panel of claim 7 , wherein the gear rack is a first gear rack, and wherein the teeth of the rotating member engage a second gear rack provided on the drawer.

9. The cable management panel of claim 1 , wherein the gear rack is provided on the drawer.

10. The cable management panel of claim 1 , wherein the radius limiter includes a curved vertical surface that limits the bend radius of cables.

11. The cable management panel of claim 10 , wherein the radius limiter includes a cable retention tab located adjacent to the curved vertical surface.

12. The cable management panel of claim 1 , wherein each drawer includes a plurality of fiber optic adapters mounted to the drawer.

13. The cable management panel of claim 1 , wherein the control mechanism is configured to move the cable take-up mechanism at half-speed relative to a moving speed of the drawer.
