Abstract

A cable management panel including chassis, a sliding drawer, and a rack and pinion arrangement. The rack and pinion arrangement including a first length of track located on an interior surface of the chassis, a second length of track provided on a drawer slide, and a gear that engages both the first track and the second track to control the movement of a sliding radius limiter mounted to the drawer.

Claims

1. A cable management panel, comprising:

a) a chassis having a top wall, opposite side walls, and a rear wall, the side walls and the rear wall defining side and rear cable access openings;

b) a drawer mounted to the chassis, the drawer being configured to slide between an open position and a closed position relative to the chassis, the drawer including a base defining open sides;

c) a slide that allows the drawer to slide between the open position and the closed position;

d) a sliding radius limiter located at one of the open sides of the drawer; and

e) a rack and pinion arrangement, including;

i) a first length of track located adjacent to one of the side walls of the chassis;

ii) a second length of track provided on the slide; and

iii) a gear that engages both the first track and the second track to control the movement of the sliding radius limiter.

2. The panel of claim 1, wherein the rack and pinion arrangement further includes a control arm, the control arm including a projection to which the sliding radius limiter is attached and mounting structure to which the gear is mounted.

3. The panel of claim 2, wherein the gear can mount to the control arm at a leftward mounting location and can also mount to the control arm at a rightward mounting location, and wherein the control arm is selectively mounted at one of the open sides of the drawer.

4. The panel of claim 2, wherein the gear is mounted to the control arm such that an axis of rotation of the gear is vertical.

5. The panel of claim 2, wherein the control arm includes a stop tab that engages the chassis to prevent the drawer from separating from the chassis when the drawer slides beyond the open position.

6. The panel of claim 5, wherein the stop tab of the control arm engages a tab formed in an edge of a bottom portion of the chassis.

7. The panel of claim 1, wherein the gear disengages from one of the first length of track and the second length of track when the drawer is in the closed position.

8. The panel of claim 1, wherein the gear disengages from one of the first length of track and the second length of track when the drawer is in the open position.

9. The panel of claim 1, wherein the slide includes a plurality of rails that slide relative to one another, the plurality of rails including a first rail attached to the drawer, a second rail attached to the chassis, and a third rail interconnected between the first rail and the second rail.

10. The panel of claim 9, wherein the relative positions of the rails of the slide can be re-adjust without disassembly of the cable management panel, the re-adjustment being facilitated by the gear disengaging from one of the first length of track and the second length of track when the drawer is in the closed position, and by the gear disengaging from the other of the first length of track and the second length of track when the drawer is in the open position.

11. The panel of claim 9, wherein the relative positions of the drawer and the radius limiter can be re-adjust without disassembly of the cable management panel, the re-adjustment being facilitated by the gear disengaging from one of the first length of track and the second length of track when the drawer is in the closed position, and by the gear disengaging from the other of the first length of track and the second length of track when the drawer is in the open position.

12. The panel of claim 1, wherein the rack and pinion arrangement has only a single gear.

13. The panel of claim 1, wherein the first length of track is formed on a plate that mounts to an inner surface of the chassis.

14. The panel of claim 13, wherein the rack and pinion arrangement is selectively mounted adjacent to one of the open sides of the drawer, such that the plate with the first length of track is selectively mounted adjacent to one of the opposite side walls of the chassis, and such that the slide with the second length of track is selectively located at the one of the open sides of the drawer.

15. A cable management panel, comprising:

a) a chassis having a top wall, opposite side walls, and a rear wall, the side walls and the rear wall defining side and rear cable access openings;

b) a drawer mounted to the chassis, the drawer being configured to slide between an open position and a closed position relative to the chassis, the drawer including a base defining open sides;

c) a sliding radius limiter located at one of the open sides of the drawer; and

d) a rack and pinion arrangement, including;

i) a first length of track;

ii) a second length of track;

iii) a control arm including a projection that projects above the one open side of the drawer, the sliding radius limiter being attached to the projection; and

iv) a single gear carried by the control arm, the gear engaging both the first track and the second track during sliding movement of the drawer to control the relative movement of the sliding radius limiter.

16. The panel of claim 15, further including a slide that facilitates the sliding movement of the drawer relative to the chassis, wherein one of the first and second lengths of track is provided on the slide.

17. The panel of claim 16, wherein the slide includes a plurality of rails that slide relative to one another, the plurality of rails including a first rail attached to the drawer, a second rail attached to the chassis, and a third rail interconnected between the first rail and the second rail.

18. The panel of claim 17, wherein the relative positions of the rails of the slide can be re-adjust without disassembly of the cable management panel, the re-adjustment being facilitated by the gear disengaging from one of the first length of track and the second length of track when the drawer is in the closed position, and by the gear disengaging from the other of the first length of track and the second length of track when the drawer is in the open position.

19. The panel of claim 15, wherein the relative positions of the drawer and the radius limiter can be re-adjust without disassembly of the cable management panel, the re-adjustment being facilitated by the gear disengaging from one of the first length of track and the second length of track when the drawer is in the closed position, and by the gear disengaging from the other of the first length of track and the second length of track when the drawer is in the open position.

20. The panel of claim 15, wherein the gear can be carried by the control arm at a leftward location and can also be carried by the control arm at a rightward location, and wherein the control arm is selectively mounted at one of the open sides of the drawer.

21. The panel of claim 15, wherein the gear is carried by the control arm such that an axis of rotation of the gear is vertical.

22. The panel of claim 15, wherein the control arm includes a stop tab that engages the chassis to prevent the drawer from separating from the chassis when the drawer slides beyond the open position.

23. The panel of claim 22, wherein the stop tab of the control arm engages a tab formed in an edge of a bottom portion of the chassis.

24. The panel of claim 15, wherein the gear disengages from one of the first length of track and the second length of track when the drawer is in the closed position.

25. The panel of claim 15, wherein the gear disengages from one of the first length of track and the second length of track when the drawer is in the open position.

26. The panel of claim 15, wherein one of the first and second lengths of track is located adjacent to one of the side walls of the chassis.

27. The panel of claim 26, wherein the one of the first and second lengths of track is formed on a plate that mounts to an inner surface of the chassis.

28. The panel of claim 15, wherein the rack and pinion arrangement is selectively mounted adjacent to one of the open sides of the drawer.
