Abstract

Provided herein is a cable tray apparatus including a first side rail, a second side rail spaced from the first side rail, and at least one support member having a first end and a second end. The second side rail includes a support wall and first and second tabs extending from the support wall. The support member includes side walls extending between the ends, and first and second recesses formed within each of the two side walls at each end. The support member is located between the side rails, and the tabs of the side rails are configured to engage and be located within the respective first and second recesses at the respective ends of the support member. The support member is slidable relative to the side rails along the tabs.

First claim

What is claimed is:

1. A cable tray apparatus comprising:
a first side rail,
a second side rail spaced from the first side rail, each side rail including a support wall and first and second tabs separately extending from the support wall; and
at least one support member having a first end and a second end, the support member including (i) side walls extending between the first and second ends and (ii) first and second recesses formed within each of the two side walls at each of the first and second ends,
wherein the support member is located between the first side rail and the second side rail, wherein the first and second tabs of the first side rail are configured to engage and be located within the respective first and second recesses at the first end of the support member, wherein the first and second tabs of the second side rail are configured to engage and be located within the respective first and second recesses at the second end of the support member, and wherein the support member is slidable relative to the first and second side rails along the first and second tabs.

2. The cable tray apparatus of claim 1 , wherein the first and second recesses are configured to be sized and shaped complementary to the respective first and second tabs.

3. The cable tray apparatus of claim 1 , wherein the first recesses have a first length, and wherein the second recesses have a second length.

4. The cable tray apparatus of claim 3 , wherein the first recesses taper inwardly from the first and second ends of the side walls to a first edge within the side walls, and wherein a length from the respective first and second ends to the first edge is the first length.

5. The cable tray apparatus of claim 4 , wherein the second recesses taper inwardly from the first and second ends of the side walls to a second edge within the side walls, and wherein a length from the respective first and second ends to the second edge is the second length.

6. The cable tray apparatus of claim 5 , wherein the first and second tabs include a bulbous shape, and wherein a length of the second tab is shorter than a length of the first tab.

7. The cable tray apparatus of claim 6 , wherein the first and second recesses include a bulbous shape complementary to the respective first and second tabs, wherein the first length is equal to the length of the first tab, and wherein the second length is equal to the length of the second tab.

8. The cable tray apparatus of claim 1 , wherein each of the first and second tabs comprise a contact face that is angled.

9. The cable tray apparatus of claim 8 , wherein each of the first and second tabs further comprise a lateral surface that connects the contact face and the support wall, wherein the lateral surface is perpendicular to the support wall, and wherein an abutment surface is formed between the contact face and a first tab end.

10. The cable tray apparatus of claim 9 , wherein the first recess includes a seating surface complementary to the abutment surface of the first tab, and wherein the second recess includes a seating surface complementary to the abutment surface of the second tab.

11. The cable tray apparatus of claim 1 , wherein the support member further includes a bottom portion and two top portions opposite the bottom portion, and wherein the two top portions extend from the two side walls.

12. The cable tray apparatus of claim 11 , wherein the two top portions include one of a straight shape and a curved shape.

13. The cable tray apparatus of claim 11 , wherein the bottom portion of the support member includes a plurality of openings formed within the bottom portion.

14. The cable tray apparatus of claim 13 , wherein the plurality of openings have a shape from the group consisting of oval, square, and rectangle.

15. A cable tray system comprising:
a first side rail;
a second side rail spaced from the first side rail, each side rail including a support wall and first and second tabs separately extending from the support wall; and
a plurality of support members, each of the plurality of support members including (i) a first end, (ii) a second end, (iii) side walls extending between the first and second ends, and (iv) first and second recesses formed within each of the two side walls at each of the first and second ends,
wherein the plurality of support members are located at different positions between the first side rail and the second side rail, wherein the first and second tabs of the first side rail are configured to engage and be located within the respective first and second recesses at the first end of the support members, wherein the first and second tabs of the second side rail are configured to engage and be located within the respective first and second recesses at the second end of the support members, and wherein the plurality of support members are slidable relative to the first and second side rails along the first and second tabs.

16. The cable tray system of claim 15 , wherein the first and second recesses are configured to be sized and shaped complementary to the respective first and second tabs.

17. The cable tray system of claim 15 , wherein each of the first and second tabs comprise a contact face that is angled.

18. The cable tray system of claim 17 , wherein each of the first and second tabs further comprise a lateral surface that connects the contact face and the support wall, wherein the lateral surface is perpendicular to the support wall, and wherein an abutment surface is formed between the contact face and a first tab end.

19. The cable tray system of claim 18 , wherein the first recesses include a seating surface complementary to the abutment surface of the first tab, and wherein the second recesses include a seating surface complementary to the abutment surface of the second tab.
