Description

DESCRIPTION

Cargo box for trucks

TECHNICAL SECTOR

The present invention refers to a cargo box for trucks, which has been conceived and structured in order to achieve a notable structural simplification of the same, without impairing its mechanical strength, so that the tare of the cargo box is considerably reduced. load.

The invention specifically affects the lateral or longitudinal walls of said cargo box.

The object of the invention is to provide a cargo box in which the lower area of the body is more reinforced, preventing the box from opening due to deformation due to the pressure exerted by the transported materials.

The invention is in the field of cargo boxes for trucks, of a metallic nature.

BACKGROUND OF THE INVENTION

Conventionally, the sides of a metal cargo box for trucks are each materialized in a rectangular frame, with a length commensurate with the length of the box and a height in turn appropriate to the load capacity provided for the truck. , a plate being attached to said frame, specifically to the two stringers and to the two vertical posts thereof, through the perimeter of the latter.

The aforementioned flat sheet is easily deformable under the pressures that the side suffers during its usual work, so the sides are reinforced with a plurality of vertical "ribs", fixed at their ends to the frame members, also by welding. and located on the external face of the sheet.

In order to achieve adequate structural rigidity, a considerable number of ribs duly distributed throughout the box is required, which have a very significant impact on both the weight of the side and the manufacturing costs thereof.

Trying to avoid this problem, the applicant himself is the owner of the utility model U201230625, which describes a cargo box for trucks that allows the use of a considerably lower number of ribs, ribs than in the case of cargo boxes of small dimensions, they can become non-existent.

For this, and more specifically each side of the box is structured by a perimeter frame based on two stringers and two vertical posts, which frames the metal sheet that constitutes the closing element of the side, with the particularity that said sheet it has a broken profile, determining a plurality of wide longitudinal grooves with a dihedral profile between which ridges are established.

As a consequence of this special configuration for the sheet, the vertical uprights of the frame, whose outer face is flat, have an internal profile that is formally and dimensionally consistent with the profile of the sheet, for a perfect mutual adaptation.

Although this structuring achieves a marked stiffening of the side of the truck body that allows the number of such ribs to be drastically reduced, the reality is that the lower area of the body is susceptible to deforming due to the pressure of the loaded materials, being able to provoke the opening of the box, with the risk that this entails.

EXPLANATION OF THE INVENTION

The recommended box for truck cargo solves in a fully satisfactory way the previously exposed problem, based on a simple but effective solution.

To do this, and starting from the structure of the cargo box described above, the invention focuses its characteristics on the fact that the last fold of the broken profile, that is, the one that corresponds to the lower end of the sheet, has a vertical configuration, which also affects the configuration of the ribs and vertical columns, achieving a structure with greater stiffening in said area, as the column-sheet assembly presents a greater width, to which must be added the fact that that the vertical configuration of this last section of sheet metal prevents the same from "opening" due to its own weight accumulated on said area, which in this case will be transmitted mainly to the bottom of the box, with a much smaller lateral component than in the case of the box described above.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a schematic view in profile and in section of a cargo box for trucks made in accordance with the object of the present invention.

Figure 2.- Shows a perspective view of the truck loading box of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the cargo box (1) for trucks of the invention is constituted, as is conventional, from two beams (2) and two vertical posts (3), which enclose as is conventional to a plate (4) that constitutes the true containing surface of the side, plate (4) that adopts a broken profile defining in it wide longitudinal grooves (5), dihedral, alternated with ridges (6) also dihedral, so that This peculiar profile of the side configures a marked structural rigidity to it, without the need to substantially increase the thickness of said sheet (4).

Both the rib (7) and the vertical uprights (3) on the side of the box, have a plate (8) with the same broken profile as the sheet metal (4), conveniently welded to their internal face, thus achieving a perfect adaptation between uprights. and ribs on the one hand and the broken sheet itself on the other, which further limits the risk of deformation of said sheet (4).

Well, in accordance with the invention, provision has been made for the lower section (9) of the plate (4) to adopt a vertical configuration, which also affects the configuration of the ribs (7) and vertical uprights (3) .

This configuration significantly increases the stiffness of the box in this area, the most delicate, preventing the sheet (4) from deforming laterally as occurred in this type of boxes.

Claims (1)

1st.- Cargo box for trucks, of the type that incorporate sides materialized in a perimeter frame, stiffened by ribs and vertical uprights, in support functions for a metal sheet acting as a container surface, sheet that adopts a broken profile, decisive of wide longitudinal grooves with a dihedral profile, which alternate with equally dihedral ridges in order to reduce the deformability of the sheet, and in which the intermediate rib or ribs, incorporate a plate with a broken trajectory, duly joined to their internal face, whose breaks they formally and dimensionally coincide with those of the sheet itself, it is characterized in that the lower end section of the broken profile of the sheet, as well as the rib or ribs associated with said sheet, has a vertical configuration.
