Description

Cable tray plug-in tray set improved

Field of the Invention

The present invention relates to a set of improved plug-in cable tray, of employees normally for mounting on floor, wall and ceiling, rails, brackets and / or any other rigid element intended for this purpose, both horizontally and vertically.

Background of the invention

The plug-in cable trays used they usually use a cover that fits over them to achieve a certain tightness in those applications that require. When it is desired to improve the tightness, the sealing is usually done by a neoprene joint or by using commercial elements with silicone base.

In the case of blind trays, fixing to the carrying elements is more complicated, due to the lack of some hole, guide and / or integrated element that allows the union of the tray and support, rail or other rigid element intended for this end.

Existing proposals achieve a degree of tightness that sometimes does not meet the requirements of the installation and, in the case of compliance, they do so with the help of Additional accessory items.

A device is therefore necessary that achieve the desired degree of tightness more simply.

Summary of the invention

Thus, the object of the present invention is provide a set of plug-in cable tray that Get a better seal easily.

The invention provides a tray assembly Enhanced plug-in cable holder, comprising a tray section cable holder and a cover, in which the tray comprises a base and lateral surfaces with vertical walls that end in incoming longitudinal channels and curved longitudinal edges upper, and the lid has a flat surface that extends laterally through vertical walls that end in channels lengths attachable with those of the tray; over the edges upper curved longitudinals of the tray are practiced short openings and, in correspondence with said openings, on the vertical walls of the lid there are some small incoming protrusions attachable in said openings; the lid It has an extension at one of its wide ends decreasing towards the corresponding extreme edge.

Through this configuration you get a greater tightness in an installation consisting of sets of cable tray and corresponding cover.

Another advantage of the. invention is that it allows remove additional sealing elements to the lid and the tray.

Other features and advantages of this invention will follow from the detailed description that follows from an illustrative embodiment of its object in relation to Accompanying figures.

Detailed description of the invention

Figure 1 illustrates two sets of cable tray unassembled and unassembled. Each set is constituted by a closed tray 1 of base 3, preferably of sheet, and a cover 2.

       \ newpage
    

Figure 1 shows that the base 3 of the tray 1 bends laterally on two lateral surfaces 4 with vertical walls These vertical walls end in channels 6 longitudinal recesses, above which two are placed 5 curved upper longitudinal edges.

The cover 2 consists of a flat surface 11 that bends laterally by side walls of short length which end in longitudinal incoming 13 channels, which are adjacent to its longitudinal free edges.

These channels 13 of the cover 2 have a shape similar to that of channels 6 in tray 1, so they are perfectly doable with them.

It is observed in figure 1 that on the edges 5 upper curved longitudinals of lateral surfaces 4 Tray 1 has made short openings 7, as a of small eyelets. On the other hand, on the vertical walls 12 of the cover 2, and in correspondence with said openings 7, there are Small bumps 14 incoming. These bumps 14 are they are at a distance from the end edge of the lid 2 such that, when the cover 2 is mounted on the tray 1, the distance of the openings 7 to the end edge of the tray 1 causes said openings 7 coincide with said protuberances 14, being securely attachable with them and thus avoiding the easy unwanted handling after assembly.

Incoming protuberances 14 of cover 2 they can serve as a guide for drilling and fixing the assembly with a Screw-plate screw if necessary for greater security of the whole.

You can also see in Figure 1 that the flat surface 11 of the cover 2 has an extension 15 of decreasing width towards one of its extreme edges, in order to optimize the tightness of the set.

The base 3 of the tray 1 can have a series of aligned 9 bulks, whose purpose is to guide the drill that allows to realize the holes for fixation to supports and / or wall. This makes it easier to fix and mount as well as save time and, therefore, the cost of such fixation and mounting. Under normal conditions, said bulk 9, slightly prominent, they are closed, so they do not affect the tightness of tray 1, increasing the resistance of the set.

You can also practice a series of drawing 10 on the base 3 of the tray 1, to reinforce the set in terms of maximum load capacity.

The presence of embuticiones 10 and bulk 9 integrated in base 3 of tray 1 allows to keep the tightness without dispensing with the characteristics of strength and safety, in addition to facilitating assembly without external elements

The side wall of tray 1 may have 8 inlaid areas, of weakened contour, which serve to fix and Support a fitting or cable outlet. These zones 8 are closed and open when fixing the fitting or corresponding element, which will attach in such a way that it does not harm the tightness of the set.

Figures 2 and 3 represent the situation final, with each of the two assemblies assembled (with cover 2 coupled on the respective tray 1) and both sets assembled together.

When cover 2 is mounted on tray 1, the channels 13 of cover 2 are introduced into channels 6 of the tray 1, the closure occurring. In addition, the bumps 14 of the lid 2 are housed in the small openings 7 of the tray 1, ensuring the tightness and safety of the whole. In figure 4 the coupling between the cover channels 13 can be seen in detail and tray 1 and the introduction of a bulge 14 of the lid 2 in its respective opening 7 of tray 1.

The existence of several bumps 14 in the side surfaces 4 of the cover 2 and several openings 7 corresponding on the top edge of tray 1 makes it can achieve couplings at several points and a better tightness and safety at the junction between lid 2 and tray 1.

In addition, the extension 15 width decreasing from the flat surface 11 of the cover 2 towards one of its extreme edges, causes said extension 15 to overlap with the flat surface 11 of the cover 2 of the following assembly, remaining below it, and that, therefore, a tightness is achieved improved on top.

Figure 2 shows that the surface flat 11 of the lid 2 is parallel to the base 3 of the tray 1 when the assembly formed by tray 1 and lid 2 is found mounted, and that the extension 15 of the flat surface 11 of a cover 2 has been arranged below the cover 2 of the next set.

Although some have been described and represented embodiments of the invention, it is evident that they can be introduced into they are modifications within their scope, not having to be considered limited to such embodiments, but only to the content of the following claims.
