Description

Quick union for fixing trays cable holder

The technical sector of this invention is the of the trays that constitute the support or support of cables in industrial facilities, and particularly for trays denominated "of thread" that are formed by a set of interlocking steel wire wires constituting parts generally in the form of "U" more or less open.

The mentioned cable trays manufactured in steel wire, they need to be joined together, because they manufactured in sections of certain lengths, to adapt to dimensions of the spaces where they are located. In this way, the Thread trays join each other to form a set that constitutes a support unit for cables and installations electric.

Indication of the prior art. The expressed thread trays, have to be joined by some of several systems.

There is a solution given by the applicant for this invention ES1035242 U consisting of a double nut wedge groove where on the one hand the grooves catch the rods and on the other the toothed nut presses the fixing clip against the rods, causing great immobilization.

However, this fixing system despite its simplification and security, could force the operator to work in an awkward position, and especially needing to use both hands, which in the new invention is avoided.

Other types of fixings are also known. for rods. There are consistent long plates that require be fixed by the action of a deformation of fins or similar by pliers. This option is less secure than the which is proposed in this invention while requiring a intervention and a more substantial and less secure effort for the result and for the operator that the simple double nut slot that constitutes the utility model ES1035242U commented.

Without being able to specify the origin, we have known about longitudinal fixations along the rods. Being one longitudinal fixation, requires great length, and a high number of fixings between every two tray sections.

There is also known some fixation formed by two parts that are assembled together; one to fix the sections of rod tray and a second fixation to secure the first. It requires skill and double work for the same fixation.

Of the known fixations, none meets the function of assembling the vertical sections simultaneously, the horizontal, maintain a uniform distance between the sections of assembled tray, and also constitutes a simple fixing and reliable that can be arranged with only one hand of the operator.

The present invention aims at a union fast for fixing cable trays that combines the advantages indicated to be of a single compact, small format, which has means to be fixed vertically and longitudinally on Tray rods, which can be applied with one hand in a single operation, and that is not elastic or excessively flexible with which a rigid and complete union is obtained.

In order to make clearer the explanation that will follow, three sheets of drawings are accompanied that in seven Figures represent the essence of the present invention.

Explanation of the invention.

The quick joint described is formed preferably for a piece of sheet conveniently bent and die cut so that it acquires a complementary form and superimposable to the near ends of the rods that form a of the so-called thread tray, so that by itself, the union generates the necessary strength for the union, without needing tools or specific gadgets for assembly, for which You can use the operator, one hand. Each cut of part 4 determines the formation of the fins 6.

Figure 3 clearly shows the insertion in the near ends of two sections of thread tray, and in them it is appreciated that two quick joints have been arranged symmetrical, so that both show fins 6 and 7 by the outside, and that the fins 7 are mounted on the rod 12 until the point at which, due to the elasticity of the material, the step 8 is within the limit of escape of the rod, so that it remains  It is trapped. This same operation is done simultaneously in the four fins 6 and 7, so that also with fins 6 is met the same operation as for step 10. Fixing could slide, except that the rods 13 get caught in the forms of semicircle or half bull 2 leaving embedded between them rods 13 the separation 3, so that also in the direction longitudinal of both separation and approach between stretches together, the fixation is effective and compact.

Fixation removal requires some more effort, it is necessary to make strength at the ends of the fins 6 and 9 on the same side and simultaneously, so that parts 10 and 8 of fins 6 and 7 stop retaining the rods and they come off one side, and can be done in the same way in each quick joint side.

The ends of the thread tray sections they are always provided with transverse pieces 13 which in the union of two sections of rod tray, are close and to the distance marking that of the semicircle or half bull forms 2 each. The ends of the thread trays that are joined, have transverse rods 13 that converge with the horizontal 12 and 16, so that the quick joint is assembled in these rods

The union holds each other, rods 13 at that lodges in the semicircles or half bulls 2, while the rods 12 are held with fins 7 and rods 16 with the fins 6. The arrangement of said fins 7 as well as fins 6, It may not be safe, except that these pieces are equipped with a double trajectory with an intermediate step 10 and 8. Said step 8 for fin 7 and 10 for fin 6, requires effort additional to interlock it so it is not likely to be accidentally separated from its fixation.

In this way, the fixing between two trays It can be done by a single operator even with one hand and without need to have any tool, which simplifies effectively the installation work of this type of trays.

An explanation of how to do it has remained implicit in the explanation of the invention.

Finally a quick union will be claimed for fixing cable trays, comprising:

- a piece preferably made of sheet metal, or manufactured in injected plastic,

- in which 5 cuts have been made and bends of which are fins 6, 7,

- said fins 6, 7 having a configuration which adopts a double trajectory with a step 8, 10 intermediate,

- and the central part being also configured of the sheet metal part 1, forming two half bulls 2 vertically arranged with an intermediate separation 3 between them,

so that fins 6, 7 are matching the horizontal rods 16, 12 of a tray thread, in which they are inserted by an elastic effort, being the two half bulls 2 also coinciding with the rods transverse 13 arranged at the ends of two trays of adjoining thread rod; fins 6 and 7 have a step 10 and 8 each one can be inserted in correspondence with the rods 16 and 12 respectively by deformation elastic

It is susceptible of industrial application, in the manufacture of unions for cable trays.
