Description

DESCRIPTION

Plastic insulating material rail for plastic cable trays and accessories

field of invention

The present invention relates to a rail made of plastic insulating material for plastic cable trays used in electrical installations to guide and support cables. The rail can also be used to support various accessories.

Background of the invention

Cable trays made of plastic insulating material are an alternative to metal cable trays commonly used in electrical installations. They have the advantage of providing electrical insulation without the need to install grounding, and also offer good resistance to the elements.

These trays rest on supports, also made of plastic insulating material, on which it is necessary to make holes to accommodate fixing elements, such as screws, in order to fix the tray to the support.

This is an inconvenience, since it is necessary to perform action on the support while the installation is being carried out, which represents an additional task for the operator.

Summary of the invention

The object of the present invention is to provide a rail of plastic insulating material for plastic cable trays and accessories that allows the drawbacks of the prior art to be easily overcome.

The invention provides a rail of plastic insulating material for plastic cable trays and accessories, consisting of a profile configured by two side wings with an "L" section that fold on the outside, and that on the inside have parallel edges and separated from each other, with both side wings joined by a central element with a “U” section with two side faces joined by an end face, the end face of the central element being parallel to one of the sections of each side wing, in which Interior extensions emerge perpendicularly from the lateral faces of the central element with a “U” section, so that the two lateral wings with an “L” section, the central element with a “U” section and its interior extensions delimit an internal channel. open top and bottom and greater width than height.

This configuration allows fixing elements to be inserted into the internal channel, thus preventing the operator from having to drill holes.

Other characteristics and advantages of the present invention will emerge from the following detailed description of an illustrative embodiment of its object in relation to the accompanying figures.

Detailed description of the invention

Figure 1 shows a rail 1 of plastic insulating material for plastic cable trays and accessories of the invention. The rail 1 consists of a profile configured by two side wings 2 with an “L” section that fold on the outside (in the representation of Figure 1 the side wings 2 bend downwards on the outside). In its inner part, the edges 3 of both side wings 2 are parallel and are separated by a certain distance. Both side wings 2 are joined by a central element 4 with a “U” section. This central element 4 has two side faces 5 joined by an end face 6 (in the representation of Figure 1 this end face 6 is located at the bottom as a base of the rail 1). This end face 6 is parallel to one of the sections of each lateral wing 2. From the lateral faces 5 of the central element 4 with a "U" section, interior extensions 7 emerge perpendicularly, so that the two lateral wings 2 with a "U" section “L”, the central element 4 with a “U” section and its interior extensions 7 delimit an internal channel 8 open at the top and bottom.

Preferably the internal channel 8 has a width greater than its height.

Likewise, the interior extensions 7 may have an “L” section and each of them may comprise a longitudinal section 9 parallel to the side faces 5 of the central element 4 with a “U” section. In Figure 1, this parallel longitudinal section 9 is the one that hangs downward, forming the free end of the “L”.

This figure 1 also represents the rail 1 of plastic insulating material of figure 1 with a screw 15 as a fixing means inserted into the internal channel 8 and with a nut 16 inserted into the internal channel 8. The configuration of the internal channel 8 of rail 1 allows the head of screw 15 and nut 16 to be inserted into said internal channel 8. This configuration avoids having to drill holes in rail 1, since fixing elements can be arranged in rail 1 in such a way. simple.

Figures 2 to 4 show a support 17 for suspension mounting. In Figure 3, the support 17 for suspension mounting is observed before being inserted into the internal channel 8 of rail 1, and in Figure 4, said support 17 is observed already installed in the internal channel 8 of rail 1 and crossed by a rod. threaded 18 to be fixed to the ceiling of the installation. The support 17 has a shape that fits into the internal channel 8 and can slide along said internal channel 8.

In Figure 1 it is observed that the lateral faces 5 of the central element 4 with a "U" section can present on their exterior part a longitudinal projection 10 in the form of a beak or harpoon. Figures 8 and 9 show a lifting piece 19, with hook-like end projections 20 configured to fit into the respective longitudinal projections 10 of the side faces 5 of the central element 4 with a "U" section.

In Figure 1 it is also observed that the sections of the lateral wings 2 with an "L" section that are parallel to the end face 6 of the central element 2 with a "U" section have a series of through holes 12 aligned longitudinally. These through holes 12 are perforations that allow the quick fixing of elements for mounting on the rail 1. Figures 5 to 7 show an accessory 21 for mooring or fixing tubes, configured to fit into the through holes 12.

Likewise, Figures 1 and 9 show a series of longitudinally aligned through holes 13 made in the end face 6 of the central element 4 with a “U” section.

Figure 1 also shows that the ends of the outer part of the lateral wings 2 with an "L" section have a longitudinal protrusion 14 in the shape of a beak on their inner face.

Although some embodiments of the invention have been described and represented, it is evident that modifications may be introduced within its scope, and this should not be considered limited to said embodiments, but only to the content of the following claims.
