LOADING BOX FOR INDUSTRIAL VEHICLES DESCRIPTION OBJECT OF THE INVENTION

The present invention relates to a cargo box for industrial vehicles, usable in any type of industrial vehicle bodywork for hauling material, both for rigid vehicles and for removals, semi-trailers, etc.

BACKGROUND OF THE INVENTION

At present, industrial vehicles with a cargo box where material is carried are known. Examples of this type will be trucks, trailers or cargo semi-trailers, etc.

The cargo box comprises a structure with a bottom and perimeter pillars on which perimetral portions (usually profiled metal plate) that shape the sides of the box are mounted, sometimes having fixed or retractable covers.

Many times in certain types of cargo, for example bulky materials, scrap, etc., when unloading the box there are cradles of the load against the sides or pillars, which slow or directly prevent the discharge, forcing to use means such as cranes or human intervention to undo the cradles, with the consequent costs. A typical example of the above is given in trucks with scrap loads, where the weight of this material, together with its shape and the vibrations due to the circulation of the vehicle, produce compactions and cradles that when lifting the truck's tipper for unloading by a subsequent broth, they can end up damaging the sides and / or pillars of the box, or even generate danger of rear dump of the truck.

The applicant does not know of any box with a system equal to or similar to that proposed in the present invention.

DESCRIPTION OF THE INVENTION

The cargo box for industrial vehicles of the invention has a configuration that solves the described drawbacks. It is of the type that comprises a structure with a bottom and perimeter pillars in which perimeter contour portions are mounted, usually profiled metal plate, which shape the sides of said box, and which according to the invention comprises first pillars which are mounted in the structure through two lower hinges perpendicular to the emptying plane of the box to allow their divergence and widening of said emptying plane during unloading. These pillars can be located around the contour of the cargo box.

The emptying plane in this document is understood to be the imaginary plane defined between the two pillars of the side or rear of the box where the material comes out or dumps during unloading.

In this way the effective widening of the box during unloading in the part where the load goes out or dumps avoids cradles, and also relieves lateral pressure on the load and releases possible compactions in the lower part of the loading area and especially at the rear of the cargo area.

The box of the invention is designed especially for dump bodies dedicated to the transport of recycling, such as scrap, but can be mounted on any type of body, both tilt (whether works, cereal, quarry, etc) as fixed, tarpaulins, semilonas, mobile floors, etc

It can be manufactured in any suitable strength material, such as steels in all its alloys, aluminum in all its alloys, stainless steel in all its alloys, and especially in any size or cubic capacity.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The cargo box (1) for industrial vehicles of the invention is of the type comprising

a structure (2) with a bottom (3) and perimeter pillars (4, 5) on which they are mounted

Perimeter portions (6) that make up the sides of the box (1), and that agree

with the invention comprises first pillars (4) that are mounted on the

structure (2) through lower hinges (7) perpendicular to the emptying plane

(11) of the box (1) to allow their divergence and widening of said plane

emptying (11) (see figs 5 and 6) during unloading, as seen in figures 2 and 4, while

that in the horizontal position of the box (1) they will be vertical and parallel to each other, as seen

in figures 1 and 3 keeping the load tightly held laterally. The box (1) can be arranged

of first pillars (4) mounted through the hinges (7) on all the pillars of the box

(1), or only have first pillars (4) adjacent to the sides or rear

provided for emptying. Specifically in figures 5 and 6, the first two can be seen

pillars (4) in the corners corresponding to the back of the box (1), since the plane

emptying (11) is the back of the box - which could have the corresponding door,

not represented for clarity. This variant of the box (1) also has other

two second fixed pillars (5) - that is, without hinges - in the two previous corners.

The first pillars (4) may comprise interlocks, not shown, to immobilize the rotation around the respective hinges (7) in the horizontal position of the box (1), and release or unlock and allow divergence of the first pillars ( 4) during download only.

Additionally, the first pillars (4) may comprise rotation dampers (8) that are related to the structure (2) (or any area integral thereto) with the corresponding first pillar (4) (see Figures 7 and 8) , so that they tend to the non-divergent position, but that can be opened during unloading, for example, said rotation dampers (8) may be rated at a resistance greater than the load they receive when the box (1) is horizontal ( see first view of figure 6) and less than the load they receive when the box (1) is lifted and loaded (see second view of figure 6), to produce their divergence and facilitate the emptying of the load.

Said dampers (8) can be for example hydraulic dampers, gas dampers, spring dampers (see figs 3, 4 and 8), and / or dampers regulated by manual or motorized hydraulic pumps (20) (see figs 1, 2, 5 and 7). In the latter case, the hydraulic pump's own load (20) is adjustable, for example by means of a crank (21) or a hydraulic power plant, not shown, to allow divergence of the first pillars (4) or to force its closed position and nestled Specifically, in the variant of figures 1, 2, 5 and 7, the dampers (8) are regulated by hydraulic pumps (20) comprising rotary actuators, immobilizing the rotation when the pump (20) has supplied pressure and allowing it when said Pressure is discharged. They may also include the shock absorbers (8) hydraulic cylinders, not shown.

Each hinge (7) ideally comprises a bolt (70) integral to the structure (2) of the box (1) and at least one sheath (71) (see fig. 7) rotatably inserted in the bolt (70) and integral to the corresponding first pillar (4), being a robust configuration. On the other hand, the sheaths (71) ideally comprise greasers (72), since the hinge (7) supports a lot of load, which increases the friction between the elements subject to movement with each other (bolt (70) and sheaths (71) ). In addition, to increase protection and prevent foreign bodies from entering the hinge (7) as far as possible, the pods (71) are provided to be

preferably arranged inside a practicable protective fairing (73),

ideally through windows (74), for maintenance. Said fairing (73) is ideally configured by a lower extension of each first pillar (4).

For its part, each shock absorber (8) comprises a fixed first half (81), which is fixed to the structure (2) of the box (1), and a second mobile half (82) that is in solidarity with the fairing ( 73).

The provision of a protection wing (10) is also provided, which is arranged inside the box (1) and covering the hinge (7) to prevent the entry of foreign bodies. Said wing (10) in the variant of figures 1 and 2 is derived from the bottom (3) of the box (1), and in the variant of figures 3 and 4 it is derived from the corresponding first pillar (4).

Finally, indicate that the hinge (7) preferably comprises a length between 20 and 60 centimeters, substantially coinciding with the width of the corresponding first pillar (4).

Described sufficiently the nature of the invention, as well as the way of carrying out it in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
