Abstract

An interlocking cable cleat secures cables to a ladder rack. The interlocking cable cleat is formed from a first cable cleat half and a second cable cleat half. Each cable cleat half includes an outer surface, an inner surface, and at least one mounting hole extending from the outer surface to the inner surface. Semi-circular keys extend from the inner surface of each cable cleat half around the mounting holes in the cable cleat halves defining slots in the remainder of each mounting hole. Each slot receives one of the semi-circular keys from an opposing inverted cable cleat half to interlock the first cable cleat half to the second cable cleat half.

First claim

The invention claimed is:

1. An interlocking cable cleat for securing at least one cable to a ladder rack, the interlocking cable cleat comprising:
a first cable cleat half having an outer surface, an inner surface, and at least one mounting hole extending from the outer surface to the inner surface;
a second cable cleat half having an outer surface, an inner surface, and at least one mounting hole extending from the outer surface to the inner surface; and
semi-circular keys extending from the inner surface of the first cable cleat half and the inner surface of the second cable cleat half, each semi-circular key is positioned around the at least one mounting hole in the first cable cleat half and the at least one mounting hole in the second cable cleat half defining slots in the remainder of each mounting hole,
whereby each slot receives one of the semi-circular keys from an opposing inverted cable cleat half to interlock the first cable cleat half to the second cable cleat half.

2. The interlocking cable cleat of claim 1 , wherein the first cable cleat half and the second cable cleat half are identical.

3. The interlocking cable cleat of claim 1 , wherein each cable cleat half has a drain hole for enabling collected liquid to drain away from the cable cleat.

4. The interlocking cable cleat of claim 1 , wherein the outer surface of the first cable cleat half and the outer surface of the second cable cleat half have ribs for strengthening the cable cleat halves.

5. The interlocking cable cleat of claim 1 , wherein the inner surface of the first cable cleat half and the inner surface of the second cable cleat half have a gripping surface for engaging cables secured between the cable cleat halves.

6. The interlocking cable cleat of claim 1 , wherein a back of the first cable cleat half has a profile wider than a ladder rung of the ladder rack and a back of the second cable cleat half has a profile wider than the ladder rung of the ladder rack, whereby the profiles allow the interlocking cable cleat to sit on the ladder rung.

7. The interlocking cable cleat of claim 1 , wherein a front of the first cable cleat half has a profile wider than a ladder rung of the ladder rack and flared ends and a front of the second cable cleat half has a profile wider than the ladder rung of the ladder rack and flared ends.

8. The interlocking cable cleat of claim 1 , wherein the semi-circular keys maintain the first cable cleat half and the second cable cleat half for uniform clamping of the at least one cable.

9. The interlocking cable cleat of claim 1 , wherein a fastener extends through the at least one mounting hole of the first cable cleat half and the second cable cleat half for securing the cable cleat halves to each other.

10. The interlocking cable cleat of claim 9 , wherein the semi-circular keys surround the fastener to protect the at least one cable from the fastener during a short circuit event.

11. A cable cleat assembly for securing at least one cable to a ladder rack, the cable cleat assembly comprising:
two cable cleat halves, each cable cleat half having an outer surface, an inner surface, and at least one mounting hole extending from the outer surface to the inner surface; wherein a key extends from the inner surface of each cable cleat half, the cable cleat halves are mounted to each other with the inner surface of each cable cleat half facing each other and the keys interlocking the cable cleat halves;
wherein each key is positioned around the at least one mounting hole in the cable cleat halves defining slots in the remainder of the at least one mounting hole, whereby each slot receives one of the keys from an opposing inverted cable cleat half to interlock the cable cleat halves; and
a fastener extends through the at least one mounting hole for securing the cable cleat halves to each other.

12. The cable cleat assembly of claim 11 , wherein the keys surround the fastener to protect the at least one cable from the fastener during a short circuit event.

13. The cable cleat assembly of claim 11 , wherein the cable cleat halves are identical.

14. The cable cleat assembly of claim 11 , wherein each cable cleat half having a drain hole for enabling collected liquid to drain away from the cable cleat.

15. The cable cleat assembly of claim 11 , wherein the outer surface of each cable cleat half having ribs for strengthening the cable cleat halves.

16. The cable cleat assembly of claim 11 , wherein the inner surface of each cable cleat half having a gripping surface for engaging cables secured between the cable cleat halves.

17. The cable cleat assembly of claim 11 , wherein a back of each cable cleat half having a profile wider than a ladder rung of the ladder rack, whereby the profile allows the interlocking cable cleat to sit on the ladder rung.

18. The cable cleat assembly of claim 11 , wherein a front of each cable cleat half having a profile wider than a ladder rung of the ladder rack and flared ends.

19. The cable cleat assembly of claim 11 , wherein the keys maintain the two cable cleat halves for uniform clamping of the at least one cable.
