Abstract: An accessory, called fixing accessory, designed to be fixed by elastic pinching, locally to wire cable tray includes, in meshed form, wires (11,12) of two different types, namely, longitudinal wires (11) and, set transversely at various spots along the longitudinal wires (11), U-shaped transverse wires (12), the assembly globally forming, as for a wireway, three panels (13,14), namely, a base panel (13) and two side panels (14).

Abstract: A device for fixing a wire to a support member in which there is at least one opening and a support member for a cable duct including the fixing device.

Abstract: The invention concerns a wire cable rack (10) for supporting and fixing electric cables (16), locally equipped with at least a fixing accessory (18), including fastening means (20, 21) through which it is made integral with the wire cable rack (10) panel which is equipped therewith, and with at least a hole (22, 23) which runs right through it, and by which it can receive any fixing element, such as a clamp fitting (17), bolt or the like.

Abstract: The invention is a coupling assembling first and second wire cable tray unit sections. The coupling is an elongate rigid strip divided into two arms with each arm provided with mounting means. The mounting means on the first arm alone rendering the coupling solid with the first tray unit section without permanent deformation of the mounting means. The mounting means on the second arm resiliently latching the second arm to the coupling without permanent deformation of the mounting means on the second arm.

Abstract: The invention concerns a coupling for assembling wire cable tray unit sections. It comprises two arms (55, 56). Means (57, 58) for mounting the first arm (55) can independently catch the coupling on the first unit section (51, 52). Means for mounting the second arm (56) on a second unit section (53, 54) comprise at least one resilient catch means (60) which can co-operate with a transverse wire of the second unit section (54) during assembly of the two unit sections. The invention also concerns a cable tray unit section comprising pre-mounted couplings.

Abstract: A cable tray is formed by a trellis of wires including longitudinal wires and transverse wires, the combination forming a trough with a bottom and sides. At least one of the longitudinal wires other than the edge longitudinal wires of the sides has a cross-section different than that of the other wires, in practice a diameter less than that of the other wires. This reduces the weight of a wire cable tray without reducing its mechanical strength.

Abstract: A bracket for cable tray type conduit carriers constituted by three principal perpendicular walls forming a trihedron, a dorsal wall, a fixing wall for fixing conduit carriers and a lateral wall. The bracket is mounted to a U-shaped rail via a rod passing through a perforation in one side member of the rail, a hole in the lateral wall, bearing on a projection in the dorsal wall and finally passing through a facing perforation of a second side member of the rail. The fixing wall is provided with a system of notches out across the edge between the fixing wall and the lateral wall, the notches dividing the fixing wall into separate islets and being surmounted by tongues provided in the fixing wall over a fraction of the length of the notches. Notches constitute housings for longitudinal wires of wire mesh cable trays, the tongues being able to be bent down onto the wires.

Abstract: A supporting element for lattice structures comprises at least one channel shaped structural section including an endwall flanked by obliquely oriented adjoining wings. Regularly longitudinally spaced securement notches are provided for securing lattice or wire cable trays the supporting element. The notches comprise longitudinally extending cutouts in each of the wings. The cutouts are defined by longitudinal and lateral edges in the wings. Regularly spaced lands extend between successive notches. Tongues longitudinally extend from the lands and partly overlying the notches. Gaps are defined between free edges of the tongues and adjacent lands. The tongues are bendable from a position generally in alignment with associated lands to a deformed position extending into the notches for restraining a section of the components between an underface of the tongues and the edges in the wings.
