SUMMARY OF THE INVENTION OF WIRE MESH CABLE TRAY

A mesh cable tray comprises a series of longitudinal wires and a series of transverse wires connected to one another at nodes to form a grid, in which each transverse wire includes a base portion from which two parallel arms extend transversely relative to the base portion so that each transverse wire is generally U-shaped. The series of longitudinal wires comprises a pair of longitudinal edge wires which are disposed beside free ends of the parallel arms of the U-shaped transverse wires. The tray has protection members arranged in the regions of the nodes at which the longitudinal edge wires and the parallel arms of the U-shaped transverse wires intersect, in order to cover the free ends of the parallel arms.

A cable-guide trough has according to the invention a row of like U-shaped cross bars aligned with one another and lying in respective generally parallel and longitudinally spaced planes and a plurality of generally parallel longitudinal bars joined to the cross bars and each having a first laterally deflected end portion carrying a first one of the cross bars and an opposite second end portion carrying a second one of the cross bars. The first cross bar and the first and portions are dimensioned to nest with the second the cross bar and second end portions of another such trough to couple the troughs together.

Thus with this system no separate clips or structure are provided. Instead the narrow end of one trough is simple fitted crosswise to the wider end of another such trough to lock the two together, completely without the use of any separate parts or tools.

According to the invention the trough has two such first cross bars spaced longitudinally apart by a distance equal generally to a diameter of the second cross bar so that the second cross bar of one trough can fit between the first bars of another such trough. It can also have has three such first cross bars and two such second cross bars spaced longitudinally apart by a distance equal generally to a diameter of the cross bars so that the second cross bars of one trough can fit between the first bars of another such trough.

Normally in accordance with the invention all the cross bars except the first cross bar are mounted inside the longitudinal bars. The first cross bar is mounted outside the laterally deflected first end portions of the longitudinal bars. In addition all the rods are of substantially the same diameter and the first end portions are deflected laterally by a distance equal substantially to the diameter.

The first end portions according to the invention can be deflected outward and the second end portions inward. Alternately the first end portions can be deflected inward and the second end portions outward. In the latter case all the rods are of substantially the same diameter and the first end portions are deflected inward by a distance equal substantial to half the diameter and the second end portions are deflected outward by a distance also equal substantially to half the diameter. The term “inward” here means that the end portions of the bars of the floor of the trough are offset upward but parallel to the longitudinal centerline of the trough and the end portions of the bars of the sides are offset inward toward each other.

In another arrangement according to the invention all of the cross bars are spaced generally uniformly and the first end portions carry two such first cross bars and the second end portions carry two such second cross bars. This ensures a substantial overlap at the connection region for a very rigid connection.

The first and second cross bars are formed with formations that fit together on engagement of a first cross bar of one trough with a second cross bar of another trough. Thus the two troughs can be clicked or snapped together to form an assembly that is unlikely to come apart in normal use.
