Description

Bulk containers

State of the art

The invention relates to a large load carrier for receiving and transporting goods and other general cargo according to the preamble of claim 1 and a kit with a plurality of base elements according to claim 10.

So far, pallets, Euro pallets and industrial pallets, in particular Europool pallets, colloquially also called Euro pallet, are used for the transport of goods. The disadvantage of these pallets is that they are not suitable to carry loose cargo, since they are just designed and have no lateral boundary walls.

For the carriage of bulk cargo is therefore resorted to large load carriers whose basic shape is formed pallet-shaped. Furthermore, large load carriers are available with similar dimensions compared to the pallets mentioned above. The advantage of the large load carriers compared to the pallets is that they can be used because of their side walls for the transport of bulk cargo. However, the known large load carriers have the disadvantage that their palette-shaped bottom firmly, that is not detachable, is always connected with exactly matching side walls. A flexible use of the pallet-shaped floor without side walls is not possible. Another disadvantage is that the known large load carrier in the unfilled state due to the fixed connection palette-shaped bottom / side wall have relatively large dimensions, even if the side walls are arranged hinged and therefore claim large storage areas. Description of the invention

The invention is therefore based on the object to provide a large load carrier, which allows a flexible connection of the side walls of a pallet-shaped floor or pallet-shaped floors of different sizes.

The object is solved by the features of the independent claims. Advantageous embodiments of the invention are characterized in the subclaims.

According to a first aspect, the invention is characterized by a large load carrier with a pallet-shaped bottom and at least one side wall. Furthermore, the large load carrier is characterized by at least one base element, which consists at least partially of plastic. The base element is detachably connected in an edge region of the pallet-shaped bottom to the pallet-shaped bottom, wherein the at least one side wall is detachably connected to the base element.

The use of a base element, which is releasably connected to the pallet-shaped bottom and to the other to be detachably connected to the at least one side wall, leads to the advantage that a flexible connection of the side walls to a pallet-shaped bottom is made possible. Due to the possibility of flexible handling, there is the decisive advantage that new, but also in use located pallet-shaped floors of different sizes can be connected via socket elements with matching side walls. As a result, conventional pallets, for example made of wood or plastic can be used. An additional time, cost and development effort for the production of large load carriers with side walls can be avoided. The use of pallet-shaped floors can be adapted to the field of application. If large pieces are transported, the pallet-shaped floor is sufficient. If small piece goods have to be transported, sidewalls can be adapted via base elements. In addition, the geometry of the base elements as well as the side walls can be easily adapted to the dimensions of already in use and newly developed pallets as well as the respective intended use. Due to the releasable connection between the at least one side wall, the base element and the pallet-shaped bottom, the further advantage is achieved that the pallet-shaped bottoms can be stacked to save space on each other.

Overall, a flexible handling is made possible by the use of the base elements with the detachable connections.

In a further advantageous embodiment of the large load carrier, the side wall is connected via a hinge connection or via a hinge to the base element. In the preferred embodiments, the base elements can be connected to the pallet base by means of nails, pins or screws, but also with clamp or clamp connections. This embodiment is particularly suitable for wood pallets and more particularly for plastic pallets or large load carriers. The nails or pins or screws can be made of metal or plastic or other material. The connection of the side wall via a hinge connection or a hinge with the base element leads to the advantage that the hinge connection or the hinge of a side wall can be temporarily folded in the direction of the pallet-shaped bottom, so as to enable a simplified loading and unloading. Furthermore, by a suitable design of the connection, a simple on or unplugging the side wall possible. The connection of the base element via a clamp connection with the pallet-shaped bottom leads to the advantage that the base element can be connected in a particularly simple manner via the clamp connection with conventional, already in use pallet-shaped bottoms, for example europallets. As a result, an optionally necessary development and cost is avoided. Rather, by simply attaching the base element to conventional floors, the advantage can be achieved that side walls can be adapted to conventional pallet-shaped floors. In a further advantageous embodiment, the large load carrier on several, releasably interconnected socket elements, in particular socket elements with at least two different shapes. By suitable combination of a plurality of base elements, it is preferably possible to form bases which fit on pallet-shaped floors of different sizes. It is particularly preferred, if the base elements are formed such that by suitable combination of several base elements pedestals can be formed, which fit on palette-shaped floors with sizes of 800x600 mm, 1,200x800 mm or 1,200x1000 mm large pallets. Due to the multi-piece design of the base elements has the advantage that the base elements can be adjusted by any combination on any floor or pallet sizes, which is why not a specific base element must be made for each pallet size. Rather, can be achieved by a skillful selection of the size and arrangement of the base elements that a variety of dimensions and thus adaptation options to different pallet-shaped floors is possible. Conventionally, palletized trays are used, for example, in pallets in sizes of 800 mm, 1200 mm, etc. Furthermore, the multi-piece design of the base elements, an additional development and cost is avoided because a flexible adaptation to different floor sizes is possible. In addition, lower manufacturing costs, since only a limited number of different parts is necessary to be able to equip a variety of pallet-shaped soils. A further advantage of using a plurality of base elements and side walls is that individual side walls can be temporarily or permanently attached or removed if necessary, for example for easier loading and unloading of the large load carrier.

In a further advantageous embodiment of the invention, the base elements form a preferably completely encircling base frame. As a result, it is advantageously achieved that completely encircling side walls surround the pallet-shaped bottom as a result of the completely circumferential base frame. In a further advantageous embodiment of the large load carrier, the base elements are connected to one another with a positive connection, in particular with a tongue and groove connection and / or a dovetail connection. As a result, the advantage is achieved that the base elements can be connected to each other by simple and inexpensive to produce positive connections.

In a further advantageous embodiment of the large load carrier, the large load carrier comprises a first and a second base element, which are preferably designed substantially mirror-inverted. The mirror-image design of the base elements allows their use with low cost and development effort.

In a preferred embodiment of the large load carrier, two first and two second base elements are arranged in the corner region of the rectangular, pallet-shaped bottom. The arrangement of the two first and two second base elements, a complete enclosure of the pallet-shaped floor can be achieved in a simple manner. In addition, the further advantage is achieved that the base elements can be arranged stackable in the loose state, so that they can be transported to save space.

In a further advantageous embodiment of the large load carrier, the large load carrier comprises third base elements, which are arranged on two opposite edges of the pallet-shaped bottom between the first and / or second base elements. As a result, the advantage is achieved that by inserting the third base elements particularly simple, the base elements or the base can be adapted to different sizes of the pallet-shaped bottom.

In a particularly advantageous embodiment, the third base elements have a different height than the first and second base elements. Thus, sidewalls of different sizes can be used, in order to finally produce a uniform upper, that is spaced from the pallet-shaped bottom end edge. It is particularly preferred if the base elements adapted are so that they can be combined with hinged side walls, for which purpose on two opposite sides of the floor equally high base heights are preferred, which are, however, different heights in adjacent pages. That is, the bottom has two opposing higher socket formations formed of higher pedestal elements and two opposite sides with pedestal formations formed of lower pedestal elements. This offers the advantage that when folding the side walls or folding the side walls so that the side walls are stored on the bottom of the large load carrier, the side walls are stacked one above the other. In addition, embodiments each having different high sides, as described in the last sentence, in combination with hinged side walls to form a complete large load carrier to the invention.

According to a second aspect, the invention is characterized by a kit comprising a plurality of mutually releasable base elements, which are at least partially made of plastic and which are suitable for releasable attachment to an edge region of a pallet-shaped bottom, so that they preferably in the edge region of the pallet-shaped bottom form completely encircling base, wherein at least one wall part is fixed to the base elements. This achieves particularly advantageous that a kit is created by a certain selection of the base elements, which can be adapted to a size-defined palette-shaped bottom. It is a particularly fast and efficient handling possible.

In a further advantageous embodiment of the kit, the base elements with a positive connection, in particular with a tongue and groove connection and / or a dovetail connection are connected to each other. As a result, the advantage is achieved that the base elements can be connected to each other by simple and inexpensive to produce positive connections.

In a further advantageous embodiment of the kit, the base elements comprise two first and two second base elements which are each used for fastening tion at one of the corners of the pallet-shaped floor are suitable. The arrangement of the two first and two second base elements, a complete enclosure of the pallet-shaped floor can be achieved in a simple manner. The first and second base elements preferably differ in the configuration of the connecting elements, such as tongue and groove, for connecting the base elements to adjacent base elements, or in their height profile, which may be higher at one end than at another end of the base element. By providing various base elements is achieved that, for example, corners can be specially designed. In a further advantageous embodiment, the base elements comprise third base elements, which are arranged between the first and second base elements in order to adapt the base formed by the base elements to pallet-shaped floors of different sizes. As a result, the advantage is achieved that the base elements or the base can be adapted to different sizes of the pallet-shaped bottom particularly simple by the third base elements.

Description of preferred embodiments

Fig. 1 shows a large load carrier 1 with a pallet-shaped bottom 2. The pallet-shaped bottom 2 is connected via two first base elements 3a and two second base elements 3b with side walls 4a, 4b. Of the first base elements 3a, only one can be seen in FIG. 1, since the other one is arranged on the rear side of the large load carrier 1.

The releasably connected two first and two second base elements 3a, 3b are arranged in the corner region of the rectangular bottom plate 2. The pedestals 3a, 3b have different heights on their respective sides, whereby side walls 4a, 4b of different sizes and heights can be used to finally return to a uniform upper, i.e. lower, height. produce from the pallet-shaped bottom 2 complained final edge.

The formation of different heights of both the base elements 3a, 3b and the side walls 4a, 4b may be a suitable means to achieve specific size adjustments, which are necessary, for example, in order to accommodate or attach suitable piece goods. Also, a height adjustment may be appropriate if side walls 4a, 4b of different sizes are to be used.

The base shown in Fig. 1 is also a circumferential base frame. This ensures that a large load carrier 1 can be produced, which is able to receive loose piece or bulk material, so as to transport it in a closed container. The closed container is produced by attaching a suitable lid. Both the pallet-shaped bottom 2 and the base elements 3a, 3b and the side walls 4a, 4b are made of plastic. However, in other embodiments, other materials such as metal, aluminum, wood, composites, etc. may be used in addition to the plastic. Overall, the use of material and the material requirement determined by the intended use, the use of plastic brings both special weight advantages and a special robustness with respect to environmental influences such as moisture, temperature fluctuations, etc. with it.

The side walls 4a, 4b are detachably connected via a hinge with the base elements 3a, 3b and the base elements 3a, 3b are detachably connected via a clamping connection with the pallet-shaped bottom 2. In addition, in advantageous embodiments, other connecting elements or connecting mechanisms such as groove joints, bolt connections, screw etc. used, which make it possible to produce a detachable connection between the side walls 4a, 4b and the base element 3a, 3b or between the base element 3a, 3b and to produce the pallet-shaped bottom 2. Clamping connections are understood to mean connections that are generated by clamps, wherein the clamps may have different shapes and configurations. For example, a simple clip connection can be made by attaching from the pallet-shaped bottom 2 or from the sides of the base elements 3a, 3b a clip in the form that it is arranged in one of the aforementioned elements and engages in the other element. In addition to clip connections, other connection options, such as groove connections, plug connections, screw connections, etc., are conceivable which make possible a detachable connection between the pallet-shaped bottom 2 and the base elements 3a, 3b.

The side walls 4a, 4b may have identical dimensions. In alternative embodiments, they may also have different dimensions from each other, and thus be optimally adapted to the size requirements. Furthermore, the side walls 4a, 4b can be formed in one piece or in several parts. Both the pallet-shaped bottom 2 and the side walls 4a, 4b can be manufactured with a closed surface as well as with recesses. If small piece or bulk goods to be transported, offers a closed surface. When transporting larger goods, for reasons of weight saving, recesses can be made in the pallet-shaped bottom 2 and / or the side walls 4a, 4b.

Fig. 2 shows a kit with two first base elements 3a, two second base elements 3b and four third base elements 3c. The base elements 3a, 3b, 3c are mutually releasably connected to each other. The third pedestal elements 3c can be used in different dimensions, and are preferably arranged between the first and second pedestal elements 3a and 3b. As a result, a simple size adjustment and handling is achieved. Furthermore, they are suitable for releasable connection to the pallet-shaped bottom 2 and the side walls 4a, 4b. The base elements 3a, 3b and 3c can be arranged in preferred embodiments on an edge region of the pallet-shaped bottom 2, so that they can form a preferably completely encircling in the edge region of the pallet-shaped bottom 2 base. In alternative embodiments, it is conceivable to arrange individual base elements individually or in combination at arbitrary positions on the pallet-shaped bottom 2 of a large load carrier 1. The base elements are detachably connected to each other. As shown in Figure 2, preferably tongue and groove connections and / or a dovetail connections are used here. However, plug and groove connections etc. are also conceivable.

3 shows a large load carrier which, in addition to the two first and two second base elements 3a, 3b, has on each side third base elements 3c which are in each case detachably connected to the two first and two second base elements 3a, 3b. The respective base elements are formed differently from one another, for example, the third base element 3c has a different height than the second base element 3b. The second base element 3b has a different height on one side than on the other side, wherein the shape of all So- ckelelemente 3a, 3b, 3c is basically freely selectable. This makes optimal adjustments to size requirements possible. The same applies to the side walls 4a, 4b and the pallet-shaped bottom 2.

4 shows a further large load carrier 1 which, in addition to the two first and two second base elements 3a, 3b, has third base elements 3c on only two opposite sides, which are each detachably connected to the two first and two second base elements 3a, 3b. In this way, a large load carrier can be equipped with a different dimension than that shown in FIG. 3 with a base.

By suitable choice of the third, the second and the first base element 3a, 3b, 3c, an optimal size adaptation of the base frame to the pallet-shaped bottom 2 can be made. Although pallet-shaped trays in sizes of 900 mm, 1200 mm are conventionally used, it can generally be stated that the large load carrier 1 according to the invention is not just a large load carrier of larger dimensions. Rather, this also means carriers with very small to very large dimensions.

Both FIG. 1 and FIG. 3 show large load carriers with completely encircling base frame and base elements 3a, 3b arranged in the corner region. It is also conceivable that the base frame is arranged only on one side of the pallet-shaped bottom 2 or on two sides in order to achieve, for example, a special protection of the piece goods to be transported.
