Abstract

A rotating radius limiter for an optical fiber cable management panel is provided. The radius limiter includes a radius limiter structure and a bracket that permit relative motion between the structure and the bracket. The structure and bracket are mounted to a sliding cable management panel. The radius limiter structure includes a curved wall, an opening for receiving cables and a trough section for retaining cables about a radius portion.

Claims

(b) a bracket secured to said radius limiter;

(i) said radius limiter being pivotally mounted to said bracket.

2. A radius limiter assembly according to claim 1 wherein:

(a) said radius limiter is pivotally mounted to said bracket at a pivot connection between said radius limiter and said bracket;

(i) said pivot connection being constructed and arranged to permit rotation of said radius limiter at least 45 degrees relative to said bracket.

3. A radius limiter assembly according to claim 2 wherein:

(a) said pivot connection is constructed and arranged to permit rotation of said radius limiter no greater than 120 degrees relative to said bracket.

4. A radius limiter assembly according to claim 1 wherein:

(a) said radius limiter is pivotally mounted to said bracket at a pivot connection between said radius limiter and said bracket;

(i) said pivot connection being constructed and arranged to permit rotation of said radius limiter between 80-100 degrees relative to said bracket.

5. A radius limiter assembly according to claim 1 wherein:

(a) said radius limiter is pivotally mounted to said bracket at a pivot connection between said radius limiter and said bracket;

(i) said pivot connection comprising a projection and track arrangement;

said projection and track arrangement including projection structure extending from one of said frame and said bracket, and said track arrangement including track structure on the other of said frame and said bracket.

6. A radius limiter assembly according to claim 5 wherein:

(a) said projection structure includes at least first and second flanges extending from said bracket;

each of said first and second flanges having a free end terminating with a hook; and

(b) said track structure having a slide surface defined by said frame for slidable engagement with each of said first and second flange hooks.

7. A radius limiter assembly according to claim 6 wherein:

(a) said projection structure further includes a pin extending from said bracket between said first and second flanges; and

(b) said frame defines a groove sized to receive said pin;

said groove being centered within said track structure.

8. A radius limiter assembly according to claim 1, wherein:

(a) said frame piece further includes a trough section adjacent to said curved wall, the trough section having a curved shape corresponding to said convexly shaped surface of said curved wall.

9. A radius limiter assembly according to claim 8, wherein:

(a) said cable entry opening is in communication with said trough section to permit cables to enter through said opening and rest within said trough section.

10. A radius limiter assembly according to claim 1 wherein:

(a) said frame includes at least one stop member to limit a range of pivotal motion of said radius limiter relative to said bracket.

11. A radius limiter assembly according to claim 10 wherein:

(a) said frame further includes at least two stop members to limit pivotal motion of said radius limiter relative to said bracket to pivot no greater than 100 degrees.

12. An optical fiber cable management panel comprising:

(a) a drawer assembly including a chassis and a drawer;

(i) said drawer being slidably mounted within said chassis;

(ii) said drawer assembly defining a storage interior and a first cable access entry to permit optical fiber cable to enter into said storage interior;

(b) a cable radius limiter slidably mounted relative to said drawer assembly; and

(c) a control mechanism secured to said drawer assembly to synchronize slidable movement of said cable radius limiter relative to slidable movement of said drawer within said chassis;

(i) said cable radius limiter being pivotally mounted to said control mechanism to permit pivoting of said radius limiter relative to said drawer assembly.

13. An optical fiber cable management panel according to claim 12 wherein:

(a) said radius limiter is pivotally mounted to said control mechanism at a pivot connection;

(i) said pivot connection being constructed and arranged to permit rotation of said radius limiter at least 45 degrees relative to said drawer assembly.

14. An optical fiber cable management panel according to claim 13 wherein:

(a) said control mechanism includes a bracket;

said pivot connection being between said bracket and said radius limiter.

15. An optical fiber cable management panel according to claim 14 wherein:

(a) said pivot connection comprises a projection and track arrangement;

said projection and track arrangement including projection structure extending from one of said radius limiter and said bracket, and said track arrangement including track structure on the other of said radius limiter and said bracket.

16. An optical fiber cable management panel according to claim 15 wherein:

(a) said projection structure includes at least first and second flanges extending from said bracket;

each of said first and second flanges having a free end terminating with a hook; and

(b) said track structure having a slide surface defined by said radius limiter for slidable engagement with each of said first and second flange hooks.

17. An optical fiber cable management panel according to claim 15 wherein:

(a) said control mechanism includes a rotating member oriented to rotate between said drawer and said chassis;

(i) said rotating member being mounted on said bracket;

(b) said drawer includes a base defining an elongated slot;

(i) said bracket being secured to said cable radius limiter at said pivot connection through said elongated slot.

18. A method of limiting a radius of optical fiber cables;

the method comprising;

(a) providing an optical fiber cable management panel including a chassis, a drawer, and a radius limiter;

(i) the drawer being slidably mounted within the chassis;

(ii) the radius limiter including a frame piece defining a curved trough section and a cable entry opening in communication with the trough section;

(b) directing optical fiber cables through the cable entry opening and through the trough section; and
