    DESCRIPTION
    Refinements for cable tray sections.
    Object of the invention.
    This invention has as its object a section of cable tray that contains an anchoring element integrated in its structure that allows joining the front end of a tray section with the rear end of another tray section to form, by assembling successive sections, the tray where the electrical wiring and / or telecommunications facilities run in the buildings.
    Especially this anchoring element is designed for the conformation of the wire trays, which are constituted by the provision of longitudinal and other transverse rods forming a grid that is bent at its sides at an angle of 90 ° to configure a channel with a base and some side walls.
    State of the art.
    The cable tray is common to be configured in the installation site itself, generally several meters high, by joining successive tray sections that have been manufactured with a certain length. It is important, therefore, to achieve a system of assembly of the sections that is easy to perform for the operator up a ladder or an elevator, and that a secure union is achieved.
    Known are the joining systems that are made using staples or other elements that require complementary screws and nuts for proper fixing. The disadvantage is that its union is difficult, requiring more than one operator for its assembly.
    From the same applicant is the Spanish patent number 1 078 809 that describes a section of tray that has an anchoring element incorporated in its front end, in the side and / or base walls, which allows the rear end assembly of the next tray section , to form the tray in the union of several sections without the need for additional accessories, this anchoring element is configured using a rod folded in two parts. The bent rod has straight parallel extensions that are welded together on the transverse rods of the tray section, and said extensions are projected beyond the end of the tray section; followed by the extensions of some bends: the first bend forms a recess towards the inside of the tray, followed by another bend that projects towards the outside of the tray. To end the anchoring element in branches that join in the fold with a "V" shape, branches through which the last transverse rod slides from the rear end of the tray section to be joined, to drop said rod into the existing hole between the first bend and the first transverse rod of the front end of the tray section having the anchoring element.
    What is intended with the improvements provided by the new invention is to provide the anchoring element with greater consistency so that the tray formed by successive joined sections can withstand different degrees of traction or large oscillations, without the disunity or detachment of no section in tray situations located in mobile structures or because of a selsm, for example.
    This tray section meets the objectives of easy assembly between the sections, without additional accessories, and fast, is performed by simply pressing the front end of the tray section containing the anchoring element, against the rear end of the tray section a link.

    Description of the invention.
    The tray sections that are the object of this invention are manufactured by means of longitudinal rods on top of which they are placed, joined by welding at the contact points, transverse rods, to form a mesh that is folded at the factory to achieve the tray section: channel with a base and two side walls. The rods, longitudinal and transverse are normally, in this type called grid or wire tray, of circular section and have the same diameter each.
    These tray sections object of the invention have an anchoring element integrated in the tray section itself, which is located in the walls and / or base of the front end of the section; said anchoring element being constituted by a bent rod containing two extensions at the opposite end to the bend that are fixed on the wall of the front end of the tray section, projecting outwardly these extensions beyond the last transverse rod, followed the extensions of two bends that make up a recess towards the inside of the tray, followed by other bends that are followed by two branches that end in the fold zone, which can be at one point, configuring a "V" shape together with the branches of the anchoring element, or in other forms, such as "U".
    This anchoring element will preferably be installed on the two walls of the tray section, and can also be installed on the base.
    When projecting the extensions beyond the last transverse rod, and then there is a bend inwards, a gap is created between this last transverse rod of the front end of the tray section where the anchoring element is installed and the first bend directed towards The inside of the tray.
    The assembly of two tray sections is produced by positioning the last transverse rod of the rear end of the tray section to be joined in the branches of the anchoring elements arranged in the walls of the front end of the receiving tray section. The operator will simply have to push this section of tray to join against the branches of the anchoring element, and the transverse rod of this section to join will slide through said branches to fall into the recess that forms the bend with the recess inwards. the tray and the last transverse rod, the two tray sections being assembled.
    As it has been said, the extensions of the anchoring element are projected in a portion beyond the last transverse rod, the length of the portion determining the gap where the tray section to be joined will be determined. Normally this portion will be adequate for the insertion of a transverse rod, but it can be projected to house two or more transverse rods of the tray section to be joined, depending on the design of other types of tray, since there are types of cable tray where One of the ends of its sections has several transverse rods placed together, which will be the ones that fit into the hole.
    The particularity presented by this inventive object with respect to the patent of the same applicant is that the branches of the anchoring elements have different inclinations between them with respect to the vertical plane of the wall of the tray section where this anchoring element is fixed; inclinations that ensure that the last transverse rod of the tray section to be joined, once fitted, cannot move and disassemble, even if the tray has large oscillations, which can be produced by the assembly process or later, with the tray already installed .

    The rod that configures the anchoring element preferably has the same circular and circular section as the rods that make up the tray section. In this way the fabrication of the anchoring element is carried out with the same product to which the tray section, rods, and the union of the anchoring element with the tray section is made by welding, just as the union of the rods transversal and longitudinal that make up the cable tray.
    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:
    - Figure 1 shows a perspective view of two sections of trays joined by the anchoring elements.
    - Figure 2 shows the front end of a tray section with the anchoring elements.
    - Figure 3 shows the rear end of a tray section sliding along the branches of the anchoring elements located at the front end of the other tray section.
    .- Figure 4 seen in another way of assembling the tray sections.
    .- Figure 5 shows two tray sections joined together.
    Preferred embodiment of the invention.
    According to the drawings, the cable tray is configured by joining successive tray sections (I, II, ...), appearing in the drawings shown two sections that we will call tray section to join (I) and tray section receiver (II); each of the sections being created by means of longitudinal (1) and transverse (2) rods, of circular section, forming a channel with a base and two side walls. Each of the sections comprises an anchoring element (3) located on each of its walls and / or base of one of its ends, formed by a rod folded in two parts, the rod being of equal section, circular, and equal diameter that the longitudinal and transverse that configure each section of the cable tray.
    The bent rod has two extensions (5), straight and parallel to each other, at the opposite end to the bend (4), which are fixed to the wall of the front end of the tray section, welded to the transverse rods (6, 7) last and last, being these extensions (5) projected out of the tray section in a portion (16) that goes beyond the last transverse rod (7), to later present two first bends (8) that make up some incoming ( 10) towards the inside of the tray, recesses (10) that are perpendicular to the transverse rod (7), at a 90 ° angle, to subsequently present a few second bends (9) towards the outside of the tray, at an angle of 90 °, being followed these second bends (9) of two branches (11) that end in the bend (4) that in this embodiment forms a "V" with the branches (11) of the anchoring element (3).
    The angle that forms the first bend (8) and the incoming one (10) is softened in its vertex with a rounded shape that has a radius of between 4 to 8 millimeters.
    The branches (11) of the anchoring element (3) project to the next section (I) to be joined, which is adjacent to the cable tray, and each of these branches (11) is divided into two

    straight portions: intermediate portion (12), from the second bend (9) to a third bend (14), and extreme portion (13), from the third bend (14) to the bend (4); straight portions (12, 13) that are located at different inclinations between them with respect to the vertical plane of the wall of the tray section where the anchoring element (3) is fixed. In this way, the intermediate portion (12) is located inside the tray, parallel to the longitudinal rods
    (I) where the anchoring element (3) is installed; and the extreme portion (13) has an inclination towards the outside of the tray, at an angle of more than 15 ° with respect to the vertical plane of the wall of the tray section where the anchoring element (3) is installed.
    As shown in Figure 5, the area presenting the fold (4) of the anchoring element (3) is located in the same longitudinal plane as the longitudinal rods (1) of the vertical wall of the tray section where it is fitted or very little protruding from said wall.
    The configuration of the tray section with the anchoring element (3) in it incorporated allows the fitting of two contiguous tray sections (I, II, ...), simply positioning the operator the last transverse rod (17) of the end rear of the tray section to be joined (I) between the branches (11) of the anchoring elements (3) arranged in the receiving tray section
    (II), facilitating the positioning of the extreme portions (13), to slide through them and through the intermediate portions (12), until they fall into the recess (15) formed between the first bend (8), the recess (10) and the last transverse rod (7) of the receiving tray section (II).
    It is also possible with this configuration another assembly mode, shown in Figure 4, in two phases: position one of the sides or walls of the last transverse rod (17) of the tray section to be joined (I) in the recess (15) ) of one of the anchoring elements (3) of the receiving tray section (II), and then turning the tray section to be joined (I) to slide the other wall of the tray section to be joined (I) over the branches ( 11), until it falls into the recess (15), of the other anchoring element (3) of the receiving tray section (II), to thereby achieve assembly.
    The stretches of asl tray together form a cable tray with great resistance. Tests have been made in the union of three sections of tray of three meters in length, forming a tray of nine meters, and oscillating its structure from the two ends with forces of displacement from top to bottom, remaining the tray unchanged, without discarding any tray section.
    Once the nature of the invention has been sufficiently described, as well as an example of preferred realization, it is stated to the appropriate effects that the materials, shape, size and disposition of the described elements may be modified, provided that this does not imply an alteration of the essential features of the invention that are claimed below.
