Abstract

A cable support device includes a body having a first bracket and a cap having a first hinge. The cable support device further includes a transition piece disposed between the body and the cap. The transition piece includes an integrally formed body portion and oppositely-facing cap portion. The body portion has an inner surface defining a body portion groove extending longitudinally from a first end to an opposite end of the body portion. The body portion further includes a second bracket. The cap portion has an inner surface defining a cap portion groove extending longitudinally from a first end to an opposite end of the cap portion. The cap portion further includes a second hinge.

First claim

What is claimed is:

1. A cable support device, comprising:
a body having an inner surface defining a body groove extending longitudinally from a first end to an opposite end of the body, the body further comprising a first bracket;
a cap having an inner surface defining a cap groove extending longitudinally from a first end to an opposite end of the cap, the cap further comprising a first hinge; and
a transition piece disposed between the body and the cap, the transition piece comprising an integrally formed body portion and oppositely-facing cap portion, the body portion having an inner surface defining a body portion groove extending longitudinally from a first end to an opposite end of the body portion, the body portion further comprising a second bracket, the cap portion having an inner surface defining a cap portion groove extending longitudinally from a first end to an opposite end of the cap portion, the cap portion further comprising a second hinge,
wherein the first bracket and second hinge form a first hinge mechanism for connecting and aligning the body and the cap portion such that the body groove and the cap portion groove define a first channel, and wherein the second bracket and first hinge form a second hinge mechanism for connecting and aligning the body portion and the cap such that the body portion groove and the cap groove define a second channel.

2. The cable support device of claim 1 , further comprising:
a body bushing having an outer surface and an inner surface, the outer surface seatable within the body groove;
a cap bushing having an outer surface and an inner surface, the outer surface seatable within the cap groove;
a body portion bushing having an outer surface and an inner surface, the outer surface seatable within the body portion groove; and
a cap portion bushing having an outer surface and an inner surface, the outer surface seatable within the cap portion groove.

3. The cable support device of claim 2 , wherein the body bushing, cap bushing, body portion bushing and cap portion bushing are each formed from an elastomer.

4. The cable support device of claim 3 , wherein the elastomer is ethylene propylene diene monomer rubber.

5. The cable support device of claim 1 , wherein the first bracket defines a first bracket slot and first opposing groove slots, the second bracket defines a second bracket slot and second opposing groove slots, the first hinge comprises first opposing hinge wings, and the second hinge comprises second opposing hinge wings, and wherein the first bracket slot receives the second opposing hinge wings and the second bracket slot receives the first opposing hinge wings.

6. The cable support device of claim 5 , wherein the second opposing hinge wings are further received into the first opposing groove slots to form the first hinge mechanism and the first opposing hinge wings are further received into the second opposing groove slots to form the second hinge mechanism.

7. The cable support device of claim 6 , wherein the cap portion is rotated to engage the second opposing hinge wings into the first opposing groove slots and the cap is rotated to engage the first opposing hinge wings into the second opposing groove slots.

8. The cable support device of claim 1 , wherein the body, the cap, the body portion and the cap portion each include flared edges.

9. The cable support device of claim 1 , wherein the body further comprises a securing structure, the securing structure comprising a mounting surface defining an aperture.

10. The cable support device of claim 9 , wherein the mounting surface comprises a plurality of legs that prevent rotation of the device when mounted.

11. The cable support device of claim 9 , wherein the securing structure includes side walls and windows.

12. The cable support device of claim 1 , wherein the body, the cap and the transition piece are formed by die casting or sand casting.

13. The cable support device of claim 1 , wherein the body, the cap and the transition piece are formed from aluminum.

14. A cable support device, comprising:
a body having an inner surface defining a body groove extending longitudinally from a first end to an opposite end of the body, the body further comprising a first bracket which defines a first bracket slot and first opposing groove slots;
a cap having an inner surface defining a cap groove extending longitudinally from a first end to an opposite end of the cap, the cap further comprising a first hinge which comprises first opposing hinge wings; and
a transition piece disposed between the body and the cap, the transition piece comprising an integrally formed body portion and oppositely-facing cap portion, the body portion having an inner surface defining a body portion groove extending longitudinally from a first end to an opposite end of the body portion, the body portion further comprising a second bracket which defines a second bracket slot and second opposing groove slots, the cap portion having an inner surface defining a cap portion groove extending longitudinally from a first end to an opposite end of the cap portion, the cap portion further comprising a second hinge which comprises second opposing hinge wings,
wherein the second opposing hinge wings are received into the first opposing groove slots to form a first hinge mechanism and the first opposing hinge wings are received into the second opposing groove slots to form a second hinge mechanism.

15. The cable support device of claim 14 , further comprising:
a body bushing having an outer surface and an inner surface, the outer surface seatable within the body groove;
a cap bushing having an outer surface and an inner surface, the outer surface seatable within the cap groove;
a body portion bushing having an outer surface and an inner surface, the outer surface seatable within the body portion groove; and
a cap portion bushing having an outer surface and an inner surface, the outer surface seatable within the cap portion groove.

16. The cable support device of claim 14 , wherein the body bushing, cap bushing, body portion bushing and cap portion bushing are each formed from an elastomer.

17. The cable support device of claim 14 , wherein the cap portion is rotated to engage the second opposing hinge wings into the first opposing groove slots and the cap is rotated to engage the first opposing hinge wings into the second opposing groove slots.

18. The cable support device of claim 14 , wherein the body, the cap, the body portion and the cap portion each include flared edges.

19. The cable support device of claim 14 , wherein the body further comprises a securing structure, the securing structure comprising a mounting surface defining an aperture.

20. The cable support device of claim 14 , wherein the body, the cap and the transition piece are formed from aluminum.
