Abstract

Hybrid cable tray comprising a first part ( 13 ) constituting one piece having a uniform thickness. The first part ( 13 ) forming at least a first support surface ( 52 ) of a first accommodation ( 53 ) for the plurality of cables ( 54 ). The first part ( 51 ) having a plurality of first through holes ( 15 ) formed by a first plurality of edges ( 20 ) in the first part ( 13 ). The cable tray ( 10 ) having two parallel extending side bars ( 11, 12 ) connected to each other by said first part ( 13 ). The said side bars comprise an inner side ( 111, 121 ) connected to the said first part ( 13 ) and provided with at least one closed top side ( 113, 123 ) and one outer side ( 112, 122 ) where the inner side and the outer side have about the same width (W). The side bars have an open bottom side ( 55, 56 ). The invention also covers a method of manufacturing such a hybrid cable tray ( 10 ).

First claim

The invention claimed is:

1. A hybrid cable tray comprising:
a first part comprising one piece having a uniform thickness, the first part forming at least a support surface of a first accommodation for the plurality of cables, the first part having a plurality of first through holes formed by a first plurality of edges in the first part; and
two parallel extending side bars connected to each other by the first part, the side bar having an inner side connected to the first part and with at least one closed top side and one outer side and an open bottom side;
wherein the closed top side of the side bar comprises two flat surfaces symmetrically arranged in the side bar with an angle α towards each other where the angle α is in the interval of 45-60° and together providing a top edge of the closed top side of the side bar;
wherein the inner side has a first width;
wherein the outer side has a second width approximately equal to the first width; and
wherein each of the side bars is substantially symmetrical about a plane bisecting the closed top side along a length of the side bar.

2. The hybrid cable tray according to claim 1 , wherein at least one side bar, preferably both side bars, is formed from the one piece.

3. The hybrid cable tray according to claim 1 , wherein at least a part of each of the plurality of edges protrudes and is directed with an angle δ away from the support surface of the first accommodation, where 45°<δ<180°.

4. The hybrid cable tray according to claim 3 , wherein the first plurality of edges of the at least one through hole is orientated at the angle δ from the support surface.

5. The hybrid cable tray according to claim 4 , wherein the first plurality of edges of the at least two adjacent through holes in the first part is orientated at the angle δ from the support surface.

6. The hybrid cable tray according to claim 1 , wherein the through holes are formed and located in relation to each other so that the plurality of edges of two adjacent through holes defines a tray member formed as a beam with longitudinally uniform cross shape at least partly between adjacent located through holes, preferably the beam having a cross section in the form of a U-profile.

7. The hybrid cable tray according to claim 1 , wherein the outer side of the side bar is provided with an outer rim extending substantially perpendicular out from a bottom edge of the outer side of the side bar.

8. The hybrid cable tray according to claim 1 , wherein the inner side of the side bar is provided with an inner rim extending substantially perpendicular inwards from a bottom edge of the inner side of the side bar and to which the inner rim of the first part is attached.

9. The hybrid cable tray according to claim 1 , wherein the inner side and/or the outer side of the side bar is provided with attachment means, preferably in the form of holes.

10. A hybrid cable tray comprising:
a first part constituting one piece having a uniform thickness, the first part forming at least a support surface of a first accommodation for the plurality of cables, the first part having a plurality of first through holes formed by a first plurality of edges in the first part; and
two parallel extending side bars interconnected to each other by the first part, the side bar having an inner side connected to the first part and with at least one closed top side and one outer side and an open bottom side, characterized in that the closed top side of the side bar comprises two flat surfaces symmetrically arranged in the side bar with an angle α towards each other where the angle α is in the interval of 45-60° and together providing a top edge of the closed top side of the side bar;
wherein the inner side and the outer side have about the same width;
wherein at least a part of each the plurality of edges protrudes and is directed with an angle δ away from the support surface of the first accommodation, where 45°<δ<180°;
wherein the first plurality of edges of at least one through hole is orientated at the angle δ from the support surface;
wherein the inner side has an inner rim extending substantially perpendicular from a first bottom edge of the inner side;
wherein the outer side has an outer rim extending substantially perpendicular from a second bottom edge of the outer side; and
wherein the inner rim, the outer rim, and the first part are disposed substantially along a plane.

11. The hybrid cable tray according to claim 10 , wherein the first plurality of edges of at least two adjacent through holes in the first part is orientated at the angle δ from the support surface.

12. The hybrid cable tray according to claim 11 , wherein the through holes are formed and located in relation to each other so that the plurality of edges of two adjacent through holes defines a tray member formed as a beam with longitudinally uniform cross shape at least partly between adjacent located through holes, preferably the beam having a cross section in the form of a U-profile.

13. The hybrid cable tray according to claim 12 , wherein the outer side of the side bar is provided with an outer rim extending substantially perpendicular out from a bottom edge of the outer side of the side bar.

14. The hybrid cable tray according to claim 13 , wherein the inner side of the side bar is provided with an inner rim extending substantially perpendicular inwards from the bottom edge of the inner side of the side bar and to which the inner rim the first part is attached.

15. The hybrid cable tray according to claim 14 , wherein the inner side and/or the outer side of the side bar is provided with attachment means, preferably in the form of holes.
