The present invention relates to a container to transport bulk products, which can be emptied especially by tipping or turning and presenting a bottom, two walls front and two side walls with at least four sections arranged one after the other, being open at the top or provided with a cover that can be opened or removed, extending the bottom of the sections out while inclined with with respect to the perpendicular, and extending the section arranged to continuation of it at least substantially perpendicular, and extending the next section inwards being inclined with respect to the perpendicular, and extending the upper section also at least substantially in shape perpendicular.

A container of this type is known by the document AU-B-430417. This container has a substantially square main body and a cover that has side walls that extend thereto time up and in, and a coverage surface which runs parallel to the bottom, formed by the hatches that can be opened and closed to introduce the product loading For unloading, a rear wall is provided discharge hatch.

For the document GB-A-2331970 a container is known for transporting bulk and similar products in wagons of railway, which is configured in such a way that its edges of exterior, upper roofs that extend in the direction longitudinal, can be varied in height through a mechanism special, so that the shape of the container can adapt to Different British standards.

In other known containers they are transported, for example, split wood, the containers being transported analogously to containers in trucks or in traffic rail freight. From DE4401295C1 a known container with a folding bottom that is composed of a body of accommodation with vertical walls and a bottom hatch unilaterally articulated to the lower side of the body of housing, being arranged on the side of the bottom hatch, opposite the axis of rotation, an interlocking device. Also in the cargo container known from EP1010645A1 for the transport of bulk products in rail vehicles, for emptied, the bottom can be turned down. They also know each other containers that can be opened by a front wall, so that The containers can be unloaded by dumping. The opening of doors on front walls or bottom hatches is little Comfortable and time consuming. The mechanisms for opening they require moving parts and, therefore, susceptible to failures, so these containers are only limited for The economic traffic of mass products. Other containers known can be emptied by rotation by means of a device emptying that has a mandrel to house and rotate the container in The bottom area. Certain dimensions of the containers are standardized and cannot be exceeded to guarantee transport insurance in rail freight traffic, for example in tunnels Therefore, the size and volume of cargo are limited. The known containers.

The invention aims to carry out a bulk product container, which can be emptied especially by turning or tipping and that can be used, preferably, in traffic rail freight, so that it presents a volume of load greater, optimized, meeting the maximum measures normalized

According to the invention, this objective is achieved by such that its cross-sectional contour in the area upper and lower zone correspond at least to a large extent to cross section and container dimensions standardized squares and that, in the central area located between stockings, be adapted at least approximately to the section cross-sectional and railroad car dimensions, corresponding the width of the container, between the sections upper side walls, width between ends lower sections that extend inclined out.

In this way, the cross section of the container is optimized so that a volume is available of significantly greater load. At the same time, it is guaranteed that container dimensions are kept within the margins of Standardized dimensions In addition, the containers made according to the invention they are adapted to the dimensions of a usual container and the dimensions of a railroad car, taking advantage of the largest possible dimensions.

According to the invention, the container is made such that the width of its cross section in the area upper and lower zone ascend respectively to approximately 2550 mm and, in the central area, approximately 2950

According to a preferred embodiment variant, the upper section is the shortest section, and the section that is extends between the inclined sections with respect to the Perpendicular is the longest.

According to another preferred embodiment, in the lower zone is provided in the lower zone a section of side wall that reaches a height of 0.3 m, measured from the bottom plate, and extending perpendicularly.

According to a preferable embodiment of the container, on the bottom plate are provided two profiles of housing for inserting fork arms of a device emptying In this way it is possible to load and unloading of the transport vehicle, whether it is a wagon of Railroad or truck.

On certain railway lines there are limitations regarding the height of the container, but in many Rail lines this is not the case. To provide the greatest possible loading volume, it is advantageous that on the container Rectangular frames of different heights can be placed.

Other features, advantages and details of the invention are now described in detail with the help of the drawing schematic representing an embodiment. They show:

Figure 1 an oblique view of a container made according to the invention,

Figure 2 the cross-sectional contour of the container according to figure 1,

Figure 3 an oblique view of a variant of a container made according to the invention,

Figure 4 a railroad car loaded with several containers, during the unloading of a container by a mobile emptying device,

Figure 5 the emptying device during the container transport and

Figure 6 the emptying device during the emptying of the container by turning.

The container 1 represented in the figures of the Drawing is planned to transport products in bulk with a low specific weight, for example, split wood, by wagons of Rail or trucks. The container 1 has two walls front 3 made identically, two side walls 2 also performed identically and a bottom plate 4, so that container 1 is open from above. During transport of the bulk product, container 1 may be provided with a tarp or similar as cover. Alternatively, you can submit a fixed cover that can be opened and closed.

In the bottom plate 4, preferably in its Inner side, there are two housing profiles 5 of approximately rectangular cross section, which extend in straight line in the transverse direction of the container 1. The distance of a profile 5 with respect to its adjacent front wall 3 corresponds to the distance of the other profile 5 with respect to its wall contiguous front 3. The mutual distance of the profiles 5 is adapted to the mutual distance of fork arms of a device of emptying 6 which is represented in figures 4 to 6.

Figure 2 shows the section outline transverse of container 1 corresponding to the contour of the front walls 3. The greatest width B of container 1 is adapted to the width of a railroad car (whose dimensions are standardized for free international use in Europe) and, according to UIC 505, it measures approximately 3 m. Just above the bottom plate 4, whose width corresponds to the width of the usual containers, following a section perpendicular 2'a short, at a height of approximately 0.3 m per above the bottom plate 4, there is a short section 2a lower side wall, extending outward at an angle acute of approximately 45º with respect to the perpendicular and that it reaches the measure of width B. Section 2a becomes in a central section 2b that extends substantially in shape perpendicular or at an angle of up to 5º with respect to the perpendicular, with inclination inwards. Following the sections 2b central side wall sections are found 2c side wall, inclined inwards at approximately 30º, which reduce the width of the container to the width in the area of sections 2'a. Following these sections 2c is find upper 2d sections of side wall that extend  in parallel with respect to the side wall sections 2'a, ending at a distance of approximately 3m, measured from the bottom plate 4. Side wall 2d sections enclose together, with the front walls 3 ending at the same height, the opening of the container 1. In figure 2, the lines dashed show the cross-sectional contour of a wagon of railroad, and the dotted lines show that of a square container

In the area of the lower and central sections 2a, 2b, 2c side wall, the cross section of the container 1 is adapted or approximated to the cross section of conventional railroad cars while sections 2'a and 2d of side wall correspond to the cross section in the lower zone and the upper zone of the usual containers for transport by road, rail or ship. A container 1 configured according to the invention takes advantage of maximum dimensions supported by UIC505 standards in traffic rail freight and therefore has a cargo volume optimized The container 1 is preferably used in the rail freight traffic, because of its maximum width require exceptional authorizations for transportation by highway.

Therefore, the cross section of the container 1 is made in such a way that in the lower area (between the short sections 2'a) present the width of a usual container, about 2550 mm, and then (in the sections 2a, 2b, 2c), corresponds to the cross section of a normalized rail car according to UIC-505 with a maximum width of 2950, presenting in the upper zone (in the sections 2d) again the width of a usual container.

Figure 3 shows a container made of analogous to figure 1, with a bottom 4, with side walls 2 and with front walls 3 and, additionally, with a frame 10 rectangular, which can be placed and whose side pieces are made with the same height, presenting, for example, a height between 25 cm and 70 cm. The frame measures match at least essentially with the dimensions of the opening of the container 1. The frame 10 is removably fixed to the container 1, whereby It is possible to change it for a frame of another height.

Additionally, it may be planned to provide a of the side walls so that it can be opened by the edge top of the container, or provide a trapdoor on the front wall That can be opened.

Figures 4 to 6 show a procedure of unloading and emptying The emptying device 6 is a vehicle that, similar to a forklift, presents two fork arms 7 arranged in a support 8. The support 8 is height adjustable along a lifting structure 9 vertical. Additionally, the support 8 is arranged so rotating with respect to structure 9, in a device not represented in the figures of the drawing. The provision is made of such that the center of gravity of a container 1 collected by means of the fork arms 7 be aligned at least essentially with the rotation axis of the motor driven rotation device. From In this way, the torque required for the turn.

Figure 3 shows the emptying device 6 while unloading a container 1 from a railroad car, It is full of bulk products. Figure 4 shows the container 1 raised during transport, and figure 5 shows the container 1 in a rotated position after actuation of the turning device, an intermediate position being represented. The container 1 is rotated until its emptying has occurred total.
