Description

TECHNICAL AREA

The invention relates to a large load carrier having the features according to the preamble of claim 1.

STATE OF THE ART

Large load carriers, which are also referred to as large containers, are out, for example DE 10 2008 047 857 A1 known. The large container described there can be designed with standard dimensions of 800 mm×600 mm, 1200×800 mm, 1200 mm×1000 mm or 1200 mm×1600 mm, depending on the desired capacity. The height of the large load carrier is typically 1000 mm, although this can be defined relatively freely, and the optimal utilization of the loading area of a truck typically has a decisive influence.

Up to 99 large load carriers of this type measuring 1200 mm x 800 mm x 1000 mm can be arranged on a standard truck, namely eleven rows of three large load carriers arranged one above the other and side by side. Stable stackability of the large load carriers is enormously important for the transport of goods.

The side walls of such large load carriers are typically also collapsible, so that a large load carrier in an empty transport position has a height of only approx. 300 mm with the same external dimensions of 1200 mm×800 mm. In the empty transport position, up to 363 such large load carriers can be transported in one truck.

EP 1 473 240 A1 discloses a large load carrier with tapered edges on the upper side on the side walls and feet, which are peripherally connected to runners. The runners are offset from the feet and have a smaller footprint than the feet. In the stack, the runners and feet stand on the sidewall surface. This results in a reasonably non-slip position of the upper large load carrier in the stack.

U.S. 2006/0260976 A1 shows a large load carrier according to the preamble of claim 1. The large load carrier has top projections on the side walls in corner areas where the side walls meet, and recesses on the feet. In the stack, the feet of an upper large load carrier are placed with their recesses on the top projections of a lower large load carrier with a precise fit. The feet and runners are otherwise on the side walls. This also results in a reasonably non-slip position of the upper large load carrier in the stack.

Furthermore, in the prior art DIN 15155/8-UIC435-3 standardized lattice box pallets known. The standard is quoted below in its 9th edition of September 2008. The lattice box pallets have a pallet substructure with external dimensions of 1200 mm x 800 mm in the foot area and typically four rigidly interconnected steel lattice walls with external dimensions of 1240 mm x 835 mm. In the case of lattice box pallets, the internal dimensions are also standardized, with a loading length typically corresponding to 1210 mm and a loading width typically 800 mm. The lattice box pallets dimensioned in this way can be stacked on top of each other, in some cases nesting, so that a stable connection is achieved in the stack.

OBJECT OF THE INVENTION

One object of the invention is to create a large load carrier with peripheral side walls, which can be used in a variety of ways and is compatible both with lattice box pallets and stacked Euro pallets. Furthermore, the large load carrier should be characterized by stable stackability.

DISCLOSURE OF THE INVENTION

The object is achieved by a large load carrier having the features of claim 1. Advantageous developments of the invention are characterized by the features of the dependent claims.

In the case of a large load carrier according to the invention, it is provided that the side walls have support surfaces for receiving feet of a similarly designed large load carrier in the stack, with the support surfaces being arranged countersunk relative to edge sections of the side walls and the edge sections at least partially surrounding the feet of a similarly designed large load carrier in the stack, and that in the stack of similarly designed large load carriers, the installation surfaces are load-transmitting and the edge sections are load-free.

In this way, nesting of the large load carriers in the stack of similarly designed large load carriers and thus also a stable combination as a transport unit is possible.

The large load carrier according to the invention is typically made up of individual injection molded parts manufactured, mostly from PP and/or HDPE, and comprises a base part and a number of feet fastened to it or formed in one piece with the base part, for example four, eight or nine feet. The foot area of the large load carrier can be freely designed to a certain extent within the scope of the present disclosure. For example, the large load carrier can have four corner feet or alternatively four corner feet and four further support feet arranged in the middle of the side walls and additionally or alternatively a support foot in the middle of the base part. The feet can be screwed, clipped or formed in one piece to the base part.

The floor member includes, for example, flat sidewall portions and typically an integrally formed floor panel.

The dimensions of the foot areas of the large load carrier preferably correspond to the standard requirements of a Euro pallet according to EN 13698-1:2003, so that the large load carrier can be handled with the same equipment shafts, in particular industrial trucks, as the Euro pallet. The January 2004 edition of the standard is quoted below. In various embodiments, the foot areas can be connected to runners, in particular to improve stability. Recesses for the tines of industrial trucks are typically present between the base part and the runners. The runners can be bolted to the feet, clipped or formed in one piece with each other.

On the underside there is thus a pallet-like structure of the large load carrier, which, in particular in accordance with the Euro pallet standardized according to EN 13698-1, can comprise runners connecting nine feet and three feet each along the long side of the large load carrier.

Four side walls are, for example, hinged to the base part in a preferably foldable manner by means of hinge elements, with rigid embodiments of large load carriers with non-foldable side walls, including, for example, one-piece peripheral side walls, also being included within the scope of the present invention.

The side walls are designed to be foldable, for example by means of hinges, but this is not to be understood as limiting the invention. Furthermore, in preferred embodiments, the side walls have foldable or removable side areas within a side wall, as in the case of a lattice box pallet. For example, one or both of the longer side walls can be equipped with side wall flaps that can be folded outwards over the lower side wall part. In the open position, the large load carrier allows access to the contents from the outside, even in the stack and even when the lid is closed. The design of the flaps in the side walls can, for example, be as in DE 10 2017 113 053 A1 be described.

The side walls include upper edge regions with support surfaces, as a result of which the large load carrier is designed to accommodate the feet of a similarly designed large load carrier in the stack. The upper edge regions of the side walls also include edge sections which preferably protrude approximately vertically upwards in relation to the support surfaces. Thus, the feet of a similarly designed large load carrier in the stack can be at least partially surrounded on the circumference.

The feet are preferably equipped with heels, wherein cross sections of the feet above the heels are designed to be larger than cross sections of the feet below the heels. The paragraphs form recesses in the outer profile of the feet and can also be referred to as recesses.

The installation areas are preferably such that they can accommodate pallets with installation dimensions of a standard size, in particular Euro pallets standardized according to EN13698-1 with installation dimensions of 1200 mm×800 mm. Accordingly, the installation areas in the area of the upper edge areas of the side walls have at least the standard size, in particular 1200 mm x 800 mm. The feet of the large load carrier preferably also form a set-up dimension of the standard size, in particular 1200 mm×800 mm.

The external and internal dimensions of the large load carrier are particularly preferably compatible with the external and internal dimensions of a lattice box pallet standardized according to DIN 15155/8-UIC435-3, so that the large load carriers and lattice box pallets can nest in one another in a mixed stack of large load carriers and lattice box pallets. Accordingly, it is preferred that the feet of the large load carrier have a set-up dimension in the standard size of the feet of the lattice box pallet.

Since the standardized lattice box pallets have the dimensions 1200 mm x 800 mm in the foot area and 1240 mm x 835 mm in the upper side wall area with internal dimensions 1200 mm x 800 mm, the large load carrier according to the invention can be stacked on a lattice box pallet. Conversely, the lattice box pallet can also be stacked on the large load carrier, since the lattice box pallet has feet with the standard dimensions of 1200 mm x 800 mm. With the measures the invention is therefore a stable mixed stacking of lattice box pallets and large load carriers possible.

The edge sections can be formed locally in the corner area of the large load carrier and/or along the side walls. In particular, it is possible to provide peripheral edge sections on the upper edge areas of the large load carrier.

In order to stabilize the stacked assembly, it can be provided that the mounting surfaces and the edge sections together have a thickness which is designed to be wider than a thickness of the side wall below the upper edge region, at least in certain areas.

In an advantageous embodiment, the side walls are equipped with vertical ribbing in the upper area, particularly in the area of the edge sections. The edge sections preferably taper upwards in the cross-sectional profile, and in particular they are designed to be beveled with respect to a plane of the side wall. This makes it possible, for example, to easily detach a cover from the large load carrier. In addition, it is advantageously prevented that due to a capillary action, water is drawn up inwards between the edge of the cover and the side wall. The bevel counteracts the ingress of water even more effectively due to capillary force.

The large load carrier can be provided with a cover which rests on the edge section and at the same time on the support surface of the upper edge area in order to achieve good load transfer of a container stacked on top.

In an advantageous embodiment, the cover includes a peripheral flange area which rests on the edge section. Because in a stack of similarly designed large load carriers, the installation surfaces are load-transmitting and the edge sections are load-free, the cover cannot jam or wedge with the edge section in the flange area when stacked, so that the cover remains easily detachable.

In an advantageous embodiment, the cover includes a peripheral apron which is beveled in particular on a side facing the inside of the large load carrier and, after it has been put on, nestles against the beveled vertical ribs of the edge section. This configuration particularly effectively reduces the possibility of water ingress through capillary forces.

The large load carrier according to the invention is particularly suitable for accommodating piece goods such as large-volume foodstuffs and in the non-food industry, e.g. in the automotive industry. Compared to conventional fruit and vegetable containers, the large load carrier is designed to be thicker and also heavier overall, so that the filled large load carriers are usually transported mechanically, in particular by forklifts and the like.

EMBODIMENTS OF THE INVENTION

In the following, the same elements are provided with the same reference symbols. There is no repeated description of the same elements in the individual figures.

1 shows a large load carrier 2 according to an embodiment of the invention.

The large load carrier 2 comprises a first side wall 4 and a second side wall 6, the first side wall 4 forming a narrower side of the large load carrier and the second side wall 6 forms a longer side of the large load carrier 2 .

In the second side wall 6 there is a side wall flap 8 which, purely by way of example, is articulated on the second side wall 6 via hinge devices 10 . The side wall flap 8 can be opened manually via a locking and adjusting mechanism and a handle opening 18 so that it is possible to access the interior of the large load carrier 2 from the outside. In this case, the cover 40, which is in 1 is shown, removed, but in some embodiments it can also be provided that the side wall flap 8 can also be opened when the cover 40 is in place. In non-illustrated embodiments, removable side wall flaps 8 can be provided.

Two label holders 12 are provided here, for example, on the side walls 4, 6, as is generally known from the prior art. The side walls 4, 6 are essentially closed, but this is not limiting for the invention. The side walls 4, 6 can also have an open rib structure, in particular towards the outside, as is known in the prior art.

In the lower area, the large load carrier 2 has feet 20, specifically in the exemplary embodiment shown, four feet 20 arranged at the corners, purely by way of example, although this is not restrictive for the invention.

The feet 20 are attached to a peripheral base part 14, for example by screwing or clipping. The side walls 4, 6 are arranged on the base part 14 so that they can be folded by means of further hinge devices 10, with complete foldability being achieved by different heights of the base part 14 in the region of the hinges.

In 1 a closed state of the large load carrier 2 is shown, with the side walls 4, 6 in particular being set up and being hooked together by means of a latching mechanism 16, which is not to be described in any more detail. The side wall flap 8 is closed and the cover 40 is also placed on top.

2 and 3 show the large load carrier 2 1 in the respective side views, it being shown here that the feet 20 are equipped with heels 22, whereby upper areas 24 of the feet 20 are equipped with a larger cross section than lower areas 26 of the feet 20.

In 3 a ribbing 32 formed in an upper area of the side wall 4 is shown, which will be discussed in more detail below.

As in 4 shown, are two similarly designed large load carrier 2 after 1 can be nested in a stack. The feet 20 of a large load carrier 2 arranged at the top are partially sunk into the interior of the large load carrier 2 arranged below. For this purpose, the large load carriers 2 have corresponding receptacles in an upper edge region 34 of the side walls 4, 6, as can be seen in particular from the detailed view in 5 apparent.

In 5 a contact area of the two large load carriers 2 stacked on top of one another is off 4 shown in section. The foot 20 of the large load carrier 2 arranged at the top can be set up on a set-up surface 36 at the upper edge of the side wall 6 . For this purpose, the side wall 6 comprises the installation surface 36 on the upper side with an adjoining edge section 30 which encloses the foot 20 of a large load carrier 2 placed thereon on the circumference. Accordingly, the large load carriers 2 in the stack are prevented from slipping sideways. As can be seen in the stack, the installation surface 36 is load-bearing and the edge section 30 is load-free.

The edge section 30 is preferably designed to taper upwards. In the exemplary embodiment shown, the edge section 30 comprises a lower region which is initially coplanar with the plane of the side wall 6 and an upper tapering region 33. The tapering region 33 is beveled both in the direction of the inside and in the direction of the outside of the large load carrier and here includes a first Bevel 35 and a second bevel 37. The first bevel 35 is located on the inside of the large load carrier 2 and serves in particular as a stacking aid for the foot 20 of the large load carrier arranged above it. Due to the incline 35, the foot 20 can be placed with a little play and is guided in the direction of the installation surface 36.

The function of the second slope 37 is explained in particular with reference to FIG 8th and 9 described in more detail.

In 6 a stacking of a Euro pallet 50 on the large load carrier 2 is shown. By coordinating the external dimensions of the feet of the large load carrier 2 with the dimensions of the Euro pallet 50 and corresponding coordination of the installation area 36, a mixed stacking of large load carriers 2 and Euro pallets 50 is made possible here. In 6 is also shown as an example that a thickness d ₂ of the installation surface 36 and the edge section 30 is increased compared to a thickness d ₁ of the side wall 4, 6 below the upper edge region 34, namely up to 50%, preferably from 10% to 30%, to allow stable stacking on top of each other.

In 7 a stacking of a large load carrier 2 with a lattice box pallet 52 is shown, with the foot 20 of the large load carrier 2 resting on a corresponding installation surface 36 . Because the lattice box pallet 52 is standardized, stable stacking in the mixed stack with the large load carrier 2 can be achieved.

8th shows a contact area of the cover 40 with one of the side walls 4, 6 in 1 . The cover 40 has a large-area rib structure 42 on the underside, which gives it inherent rigidity. At least one rib 43 of the rib structure 42 of the cover 40 rests on the set-up surface 36 in the “closed cover” state.

On the upper side, the cover 40 has a further support surface 39, the dimensions of which are the same as the support surface 36, in order to be able to accommodate another large load carrier 2, another Euro pallet 50 or a lattice box 52 in a stack above it (not shown).

The cover 40 comprises a flange area 46 with an outer skirt 44. The skirt has a third bevel 48 on the inside, which is designed to nestle against the second bevel 37 of the edge section 30.

9 shows the contact area 8th in a perspective view. The edge section 30 of the side wall 4, 6 comprises a continuous inner wall 38 with the described first slope 35 and the ribbing 32 with the described second slope 37. Due to the inclined position and withdrawal of the edge section 30, the cover 40 lies flush with its apron 44 on the side wall 4, 6, which among other things also reduces the risk of injury.

The inclined position and the rib structure in the edge section 30 also reliably prevent water from entering the interior of the large load carrier 2, which is closed with the lid 40.

The invention is not limited to the exemplary embodiments described here. Rather, within the scope of specialist knowledge, a large number of modifications are possible.
