Description

Container with folding side walls for bulk materials.

Object of the invention

The present invention, as expressed in the statement of this specification refers to a container with foldable side walls for bulk materials whose essential purpose is to provide a container with folding side walls incorporating a folding system of its walls before folding, thus optimizing the space container occupied once folded. Said container is planned for the transport of bulk materials and can be used in the logistics and transportation industry of different materials and / or pieces; not discarding though other applications of the invention.

By folding the container is optimized its cycle of use, so that once empty it facilitates its transport to its starting position of the corresponding cycle in which would load the material to be transported again.

Background of the invention

Various types of containers are known folding for the logistics industry and the transport, incorporating these various known containers implementations of the folding of its walls to optimize the cycle of use of the corresponding containers.

Thus, two examples of these containers Conventional ones are those reflected in EP 1910275 and ES 1020520, these containers being embodiments with certain folding systems of its walls, very different not However, as any average expert in the field can appreciate, the container provided by the present invention.

We do not know in the current state of the art no container that presents a type of folding in its walls sides similar to that facilitated by the invention, with first folding sectors prior to dejection and providing three different heights in the container configuration.

Description of the invention

To achieve the objectives and avoid drawbacks indicated in previous sections, the invention It consists of a container with folding side walls for bulk material, presenting the container or box a bottom, with minor sides or front and side sides or sides and being foldable at least two opposite sides of those referred sides.

Novelly, according to the invention, each of said foldable sides is composed of an upper section and a section lower, establishing first means of articulation and / or fixing between said sections and second articulation means and / or fixing between the lower section and the rest of the container, the size of the upper section being less than half of the section lower and settling for opposite sides the sense of folding of said first means in the same direction; from so that having folded on one side, at act on the first and second means, and on the side opposite on the first means, you can act on this side opposite about the second means to stay the sections upper, of said opposite sides, coplanar, parallel to their lower sections parallel to the bottom of the container.

According to the preferred embodiment of the invention, The container has a rectangular contour in which referred to foldable sides, with lower section and with upper section, they are set only on the major sides of the box or container; while the smaller sides are folded conventional by means of inward folding.

In addition, in the aforementioned preferred embodiment, the sides, bottom, sections and means, that is, the container in its Totally, it is made of plastic material.

The aforementioned first means and second means are likely to be means of articulation and / or fixation conventional.

In one of the preferred embodiments of the invention the aforementioned upper sections include parts of closure that can be connected to the smaller or front sides, equipped with a tilt shaft, a latch that penetrates or exits the corresponding minor side as it is in the locked position or release of the latch, and a flexor element whose pressure enables said release position; presenting the main body of this closure piece an "L" section which facilitates a gap for the user's fingers in operations of extension and collection of the upper sections.

With the structure described, the container of the invention has the advantage that it facilitates a novel type of folding, with means of easy realization and simple use, providing a container that optimizes the occupation space through a very different original realization of those existing in the state of the art.

Then, to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Description of an embodiment of the invention

Following is a description of a example of the invention with reference to numbering Adopted in the figures.

Thus, the container with side walls Foldable for bulk materials of the present example is a container or box 1 with two minor sides or 2 heads, with a bottom 3 and with larger sides or sides determined each of them by an upper section 4 and by a lower section 5, according to It can be seen in Figures 1 and 2.

Between each upper section 4 and lower section 5 there are first means of articulation and fixation 6, while  that between each lower section 5 and the rest of container 1 is they have second articulation and fixing means 7, according to It can be seen in figures 1 to 3.

In the present example, container 1 presents a rectangular contour on which sides are established folding according to the invention that correspond only to the larger sides of container 1, but in other examples you could use this type of folding for the smaller or front sides, or for the four sides of the container, the same being done type of folding on two opposite two sides. In the present example, minor sides 2 have a conventional folding through inward dejection.

Also, in the present example both sides 2, as the bottom 3, the upper sections 4 and lower 5, and the first means 6 and second means 7, that is, the entire container 1 is made with plastic material, but in others embodiments of the invention could be employed other materials.

On the other hand, in the present example the referred to first means 6 and second means 7 are means of conventional articulation and fixation, but in other embodiments articulation and / or design fixing means could be used specific.

In the present embodiment of the invention, the upper sections 4 include closure pieces 8, shown in Figures 5 to 9, which connect the smaller sides or heads 2 with said upper sections 4. These pieces, as stated for The rest of the container, can also be made with material plastic.

Each closure piece 8 is provided with an axis of tilting 10 and a latch 9 that penetrates or exits the corresponding minor side 2 determining the locking positions and release shown in figures 5 and 6.

In addition, each closure piece 8 includes a flexor element 11 whose pressure enables the position of release of figure 6.

On the other hand, each closure piece 8 is equipped with a section in "L", as shown in figure 7, which provides a gap 12 for the user's fingers in the extension and collection operations of the corresponding tranche top 4.

By including these closure pieces 8, the folding of the upper 4 and lower 5 sections on one side must be done simultaneously, since the side walls from the smaller sides 2 would prevent the folding of the upper section 4 on the side that said folding is made inwards due to the retention system determined by closure pieces 8, of so that the container only has two useful positions, one in which is fully folded which is the position of storage and another one in which it is fully deployed which is loading position

In the folding of the container one of the sides older with its sections 4 and 5 it folds in zigzag, while on the opposite side the two sections 4 and 5 fold in the same direction inside the container.

So that folding can be done according to the invention, the upper sections 4 must be less than half of the size of the corresponding lower sections 5, so that the folded upper section 4 adapts to the space provided by the staggering of the folded and folded opposite side, as you can can be seen in figure 3. This use of space is facilitates due to the same sense of dejection of the sections 4, as shown in figures 1 to 2.

The folding process of the container is shown sequentially in figures 1 to 4, so that the container fully deployed (figure 1) proceed to folding of an upper section 4 and the corresponding lower section 5 in zigzag (figure 2). Next, a opposite side inwards, folding its two sections but instead zigzag in the same direction (figure 3) to finally the two upper sections remain 4 coplanar in the background 3 of the container (figure 4). Obviously, the deployment of container is made by reverse steps to those described to the folding.
