DESCRIPTION

Transport plate for items in bags

The present invention relates to a transport plate for transporting goods by industrial vehicles, such as forklifts and transpallets.

For the horizontal transport of stackable goods, transport pallets are most often used which, by means of industrial vehicles, in particular forklifts, are lifted, transported and placed again in another place. However, such transport pallets have various disadvantages. Thus, for example, the standard Europool pallets have their own height of 144 mm, which must be taken into account with a maximum predefined height of the stack of items together with the pallet of, for example, 2000 mm and goes to shore of the quantity of the articles. In addition, the pallets also have a high own weight that must be taken into account in the carrying capacity of the respective means of transport, for example, truck and, therefore, less goods can also be transported. Certainly, conventional pallets always have a flat or flat loading surface, however, precisely the wooden pallets have the disadvantage that wood chips, nails or staples can tear the bags or the sacks wrapped. In addition, wooden pallets most of the time do not meet the necessary hygiene provisions, for example, for the transport of food. In addition, wooden pallets break very easily and sometimes have to be replaced even after the first intervention. A new wooden pallet not only carries costs, but also at the expense of the environment. Finally, the usual pallets (Europool), be they wood, plastic or metal, in the return transport without articles require considerable space.

Therefore, in some cases the so-called slip sheets have been used instead of pallets, as disclosed, for example, in US 5,503,517 A. In this regard they are thin Corrugated cardboard or plastic mats that are used as the basis for the items to be transported (see Figure 19). They have a height of only a few millimeters, so that in such sliding sheets compared to the Europallets, approximately 10 to 15% more items can be stacked. However, the great disadvantage of these sliding sheets is that the mat that is flat on the base with the items stacked above can only be raised with difficulty. To arrive with the help of a forklift truck ultimately under the sliding plates, they have marginal lips placed upwards on one or several sides, so that the sliding plates are generally longer and wider than the stack of items above (see Figure 20). In addition, these sliding blades do not have any type of stability of their own, so that they cannot be lifted with conventional forklift forks, but only with wider fork-pin adapters or a complete plate. To this belong also the so-called Roller Forks® developed especially for this. In addition, there is a risk that the items in the battery that have to be tilted slightly during the introduction of the fork or forklift plate, slide against each other or even tip over the entire battery.

US 3,587,481 A shows a pallet with an essentially flat upper platform that serves to house the articles and in which V-shaped cavities that form the support feet or pallet skates are configured.

US 4,550,830 A shows a container that can be assembled from a bottom, a central side wall frame and a lid. The bottom has a perimeter groove in which the central side wall frame (12) is inserted. The bottom is composed of two plastic plates assembled in the so-called double sheet procedure, whose marginal sections are stretched laterally outwards.

From DE 76 22 928 U1 and US 3,680,495 A, pallets with exit perforations are known to prevent liquid from accumulating on the plate or on the support feet.

From WO 2001/34484 A1, a thin pallet similar to a "sliding sheet" is known for the transport of so-called "bulk bags", that is, large stable bags of fabric, the pallet being adapted to the size of the bag in bulk and presenting housings for the forklifts of the forklift that are configured in the form of tunnel profiles applied on the pallet or as bulges in the pallet. However, this type of pallet is only suitable for the transport of large units of this type in itself, such as bulk bags in which the pallet forms only a kind of separator between the bottom and the bulk bag to arrive with the Forklift forks for lifting under the bulk bag. In the elevated state, the pallet serves only as an intermediate layer for the transmission of force between the forklifts of the forklift and the bulk bag essentially with dimensional stability. However, this pallet does not represent any base with stability of its own or form that could support the transport of several sacks arranged side by side in a loose way and stacked on each other, for example, several strata of 5 x 25 sacks kg of thin PP sheet, which could slide with respect to each other. Therefore, they are not suitable for transporting transport units without their own stability.

Against this background, the objective of the present invention is to create a means of transport that simplifies the transport of goods, in particular of items in stacked bags, which can be produced simply and

economic, does not require any type of assembly or adaptation of industrial vehicles and allows space-saving storage of the means of transport itself.

This objective is solved by means of a transport plate with the characteristics of claim 1.

Advantageous configurations of the invention are subject to the dependent claims.

In the case of the transport means according to the invention, it is a plate that itself is formed in such a way that it has at least two tunnel-shaped bulges separated from one another for the accommodation of forklift forks. This transport plate according to the invention combines, respectively, the advantages of the pallets or sliding plates described at the beginning. The plate itself allows a constructive form with material savings with simple production and reduced weight. "In itself formed" in the sense of the invention means that the entire plate or the base structure of the plate has an essentially uniform wall thickness.

Due to the tunnel-shaped bulges, you can drive without resistance and without special accessories for the forklift with normal forklift forks under the transport plate resting on the ground, without tilting the stack of items or dragging with the forks of the forklift on the ground or the transport plates, since the transport plate in the tunnel-shaped bulges offers a sufficient separation of the support surface for the introduction of the forklifts of the forklift.

Since the transport plate itself is formed, several transport plates with the same construction can be stacked or nested in each other, engaging the tunnel-shaped bulges with each other. The ownership of a piece of the transport plate does not require any type of assembly of the transport means before use. In addition, unlike the sliding plates mentioned in the introduction, no marginal lip protruding above the stack of articles is required, so that even the lateral dimensions of the transport plate can be adapted to the respective stack of articles and several stacks of articles can be placed closely adjacent.

Because of the essentially smaller height compared to a usual Europool pallet, at least one additional layer of bags such as, for example, sacks of bags, can be transported on the transport plate according to the invention by pallet position in a container 5 x 25 kg

The tunnel-shaped bulges serve not only to accommodate forklift forks, but also act as oversized grooves that, in their entirety, stiffen the plate. For this reason, the transport plate obtains without certain measures or the use of additional material a certain stability of its own that at least is sufficient so that the plate together with the stack of articles can be lifted with usual forklift forks.

In addition, the transport plate according to the invention has a perimeter edge angled with respect to the plane of the plate up and / or down that also contributes essentially to increase the strength or stiffening of the transport plate. An upwardly angled edge, that is, extending in the direction of the bulges, apart from the stability effect, also has a certain fixing effect, such that the stacked items can be held laterally by this edge and the stack of Items does not slip from the transport plate.

Certainly, due to the tunnel-shaped bulges, the transport plate according to the invention loses its flat surface. However, a flat surface precisely in the case of items in bags has a rather minor importance, since bags or bags are usually full of loose or movable items or materials with respect to each other, which can be adapted to some extent to the bulging in the form of a tunnel. This even has the advantage that the lower bags are placed around the tunnel-shaped bulges and, therefore, even a side slip of the stack of items of the transport base is avoided.

The tunnel-shaped bulge can have the most diverse forms such as, for example, the shape of an inverted "U" or inverted "V". However, it has been shown that precisely a wavy shape with larger radii not only increases stability, but also takes more care of the stack of articles, since no sharp edges are pressed in the article.

Since the tunnel-shaped bulges are molded in the transport plate and are open downwards, they can also be produced easily in the deep drawing or injection molding process without having to use any type of insert or male or other auxiliary means.

In order not to increase the height of the transport plate by the marginal sections placed or angled upwards, the marginal sections are configured such that they do not protrude above a plane that is defined by the outer vertices of the bulges.

To increase, on the one hand, the resistance of the bulges, however, not the height of the transport plate, the marginal sections in the area of the bulges may be placed down, be reduced or even completely removed, since This area is already stiffened by the bulges.

In the transport plate according to the invention, the entire plate may have an essentially uniform wall thickness or be reinforced with material in the area of the bulges. Depending on the material selection and the base thickness of the transport plate, reinforcements may be necessary in the area of the bulges. However, it has been shown that a plastic plate, for example, of polymers such as, for example, PE or PP with a thickness of 2.5 to 5 mm meets the usual requirements.

A reinforcement of material may be indicated in the area of the bulges also in view of manifestations of wear and less for reasons of stability, since the forklifts of the forklift act there. For example, the internal area of the bulges may be provided with a highly sliding and low wear material.

The length and width of the transport plate can essentially have the usual dimensions of a Europool pallet or industrial pallet, in particular 1200 x 800 mm, 1200 x 1000 mm, 1300 x 1100 mm or 1140 x 1140 mm, such that The transport plate according to the invention is compatible with the infrastructure and environment that are aimed at Europool pallets.

The transport plate according to the invention has in particular the advantage that it can be designed very flat and therefore allows the stacking of more articles on the transport plate. For this, the free height of the bulges in relation to the bearing surfaces of the transport plate should have at least the minimum introduction height of forklift forks. The proper height of the transport plate can be kept low in favor of greater transport of articles when the bulges are oriented only to the height of introduction of forklift forks and not also to that of transpalés forks which, because of the rollers integrated in the forks, clearly is greater. When the free height of the bulges amounts to 70 mm and the thickness of material amounts to 5 mm, with a total height of the transport plate of 75 mm with respect to a Europalé with 144 mm an additional plane of bags can be placed on the transport plate without exceeding the maximum loading height of 2000 mm. Therefore, with the same cargo space by means of the transport plate according to the invention, more articles can be transported than with a Euro-pallet.

The standard width of forklift forks is generally 100 to 120 mm. To limit, on the one hand, the bulges to a minimum dimension, on the other hand, facilitate the introduction of forklift forks into the bulges, the free width of the bulges can preferably be in a range of 240 to 260 mm . Therefore, advantageously, the free width of the bulges can be selected approximately twice as large as the width of the forklift forks.

The tunnel-shaped bulges can be arranged in pairs, each pair of bulges with axial symmetry being arranged with respect to a central axis of the transport plate. This ensures that the transport plate is in equilibrium when it can be lifted by the forklift. In this regard, for example, pairs with different separations may have a path in the same direction or transversely with each other.

The bulges can be extended only partially or along the entire dimension of the plate. The latter facilitates, because of the symmetrical design, not only the production and stacking of the transport plates, but also allows forklift forks to be introduced from two opposite sides, so that the handling of the plate Transportation is not limited to one side. In addition, in this design it is not important how long the forklift forks respectively used are, since they can protrude on the opposite side beyond the transport plate.

According to an advantageous aspect, the transport plate has two pairs of tunnel-shaped bulges that have a parallel path to each other, being arranged in the form of a grid, that is, that the direction of one of the pairs of bulges It is perpendicular to the direction of the other pair of bulges. Thanks to these grid-shaped bulges on the transport plate and intersected with each other, the transport plate becomes substantially more rigid, since regardless of from which side the transport plate with forklifts is raised lifting, bending forces are absorbed by tunnel or arc shaped bulges that have a perpendicular travel respectively with respect to this. Another advantage is that the transport plate can be lifted from four sides and, therefore, the handling of the transport plate with the stack of articles can be designed substantially more easily and flexibly. The separation between the bulges of the first pair and the bulges of the second pair can be differentiated from each other. This allows the handling of the transport plate with different fork widths without having to adjust the forklift separation of the forklift from each other. Therefore, the probability that one or the other separation is suitable for the width of the fork is substantially increased.

In addition to the stiffening ribs according to the invention in the area of the bulges, as already mentioned, the thickness of the material and / or the plate can be increased in its entirety or even only a zone of the bulges locally can be provided with other geometries or elements that reinforce the stability integrated in the plate. Therefore, the resistance of the transport plate can be increased in a directed manner in places where this is necessary. Such geometries that reinforce stability can be stiffening ribs or grooves that have a longitudinal, transverse and / or perimetral direction travel and / or also be projections or cassette-shaped cavities configured as a single piece on the transport plate. In this regard, the geometries that reinforce stability are designed in such a way that they do not form sharp edges or corners that could lead to damage of the items to be stacked. Preferably, the geometries can be configured exclusively on the lower side, that is, the side opposite the articles.

When the transport plate is produced in the injection molding process, it is advantageous that the wall thicknesses of the geometries that reinforce the stability essentially correspond to the wall thickness of the transport plate to thereby prevent deformation and stretching of the pieces during hardening.

In order not to fully increase the dimensions, in particular the height of the transport plate, it is advantageous that the geometries that reinforce the stability do not protrude above a plane defined by the outer vertices of the bulges or above a plane defined by the support points of the transport plate. Therefore, cavities are provided, especially or exclusively, in the area of the bulges, while in the transitions to the other sections and in the other sections, nerves are provided, above all or exclusively. The ribs or stiffening grooves are particularly effective when they have a transverse route with respect to the bulges. Therefore, they can be arranged accordingly.

To stabilize the projections or cavities as a cassette, they can be additionally provided with stiffening ribs arranged in a grid.

For weight reduction, selected sections of support may have notches or recesses, since they are relatively little requested. Through these notches at the same time you can save material. These notches also prevent so much dirt or some kind of liquid from accumulating, for example, during cleaning, on the transport plate.

When the transport plate is composed of plastic, it can not only be produced easily in the injection molding process or deep vacuum drawing process, but also meets hygienic requirements, since they can be cleaned more easily and cannot be contaminated, in such a way that it can be used to transport food, in particular vegetables, which in particular in case of wooden pallets leads to problems.

All the geometries, or at least some selected ones, directed in a vertical direction such as the edge, the side walls of the stiffening grooves, etc., are preferably placed in a slightly conical shape to allow, in this way, a complete nesting of several transport plates with each other.

When the transport plate has placed or inclined surfaces, such as the edge or geometries that reinforce stability, the transport plates can be engaged when two or more transport plates are nested together. Therefore, the transport plate according to the invention can have integrated separators

or configured in one piece to keep two transport plates stacked on top of one another or nested on each other.

These separators can be made as projections or ribs that are configured on the lower side of the transport plate. The projections may be configured within ribs or stiffening geometries, such that they do not increase the height of the transport plate in its entirety. Because of these separators, the contact surface between the transport plates that are located one above the other can be reduced, so that the transport plates do not engage or do not engage so easily. In addition, transport plates somewhat spaced apart can be separated more easily, for example, by a forklift.

The upper side of the transport plate may be provided with cavities that can accommodate the corresponding ribs or projections of separation on the lower side of a transport plate placed above. These cavities prevent the protrusions and, therefore, the transport plate from sliding laterally when they rest on the surface of the stiffening ribs. Therefore, it can be ensured that even high piles of transport plates remain stable.

according to the sixth embodiment.

Detailed description of preferred embodiments

Figure 1 shows a transport plate 10 that is suitable for transporting goods, in particular items in stacked bags. The transport plate 10 is essentially rectangular in shape and essentially corresponds in size to the usual transport pallet formats. The base body of the transport plate 10 is itself flat and has a thickness of only a few millimeters, for example, approximately 2.5 to 5 mm and has four bulges 12, two of the bulges 12 having a parallel path between yes and separated from each other in the longitudinal direction of the transport plate 10 and two of the bulges 12 also having a parallel path to each other and separated from each other in the width direction of the plate 10. As can be seen in Figure 1 , the four bulges 12, therefore, have a grid shape and are interlinked in shape. For stiffening, the plate 10 also has a perimeter edge 14 which extends with respect to the base body of the plate 10 approximately 90 ° upwards. The corners of the thin transport plate 10 are rounded and reinforced by the edge 14 to prevent the transport plate from breaking there. In addition, round corners have the advantage that during transporting items with the transport plate 10, other items can not be so easily damaged, for example, another stack of items or the package (see elastic sheet container in Figure 19) tear as would be the case, for example, with sharp and sharp corners.

The transport plate 10 is also reinforced locally in the area of the bulges 12 by stiffening ribs 16, the stiffening ribs 16 being arranged essentially transversely with respect to the extent of the respective bulging.

Figure 2 shows the lower side of the transport plate 10. The lower side of the transport plate 10 has multiple flat support sections 18 that are separated from each other by the bulges 12. When the plate 10 is placed on a flat base , then the transport plate 10 is flatly supported on all the support sections 18. On the contrary, in the area of the bulges 12, the transport plate is separated from the ground, so that forks can be introduced there of forklift under the transport plate 10.

As can be seen in Figures 1, 2 and in particular in Figures 5 and 6, which show side views of the transport plate 10, the bulges 12 are configured in the form of a tunnel or an arc. When the transport plate 10 is on a surface, the bulges form a kind of barrel vault. Particularly because of the arc shape, the bulges 12 can absorb vertical loads and apply them through the support sections 18 in the base. As can be seen in Figures 3 and 4, the vertices of the bulges 12 or the support sections 18 form two planes E1 and E2 parallel to the plane with each other. Therefore, with the transport plate 10 according to the invention, items in bags or other elastic articles that adapt to the bulges 12, but also large surface products, cannot be transported alone, as mentioned in the introduction , since they rest flat on the bulges that make up a flat grid plane.

Because of its shape, the plate 10 can be produced very simply in the injection molding process or deep vacuum drawing process from plastic, for example, polyethylene or polypropylene, such that the transport plate 10 according to the invention is characterized not only by its reduced weight and the possibility of its reuse, but also by its reduced parts costs.

Figures 5 and 6 show side views of the longitudinal or transverse side of the transport plate 10. In this regard it can be seen that the separation D1 of the bulges extending in the transverse direction is greater than the separation D2 of the bulges extending in longitudinal direction. This has the advantage that the same transport plate 10 can be transported with forks of different widths without having to modify the spacing of the spikes when introduced according to the spacing of the spikes of the fork thereof from the longitudinal or wide side below the transport plate 10.

Figure 7 shows an enlarged partial view of a bulge 12. The free height h of the bulge 12 is selected such that, on the one hand, forklift forks can be introduced into the bulges 12 when the transport plate 10 is supported on the ground and, on the other hand, the bulges 12 contribute only minimally to the total height H of the transport plate 10 to be able to place, with the maximum predefined height, the greatest possible amount of articles on the transport plate 10 It has been shown that with a free height of approximately 70 mm and a plate wall thickness of 3 to 4 mm, twelve 25 kg pellet bags can be stacked without exceeding the maximum height of 2 m. In comparison with this it is mentioned that in an Europalé only eleven planes of such bags can be stacked.

In order not to hamper the introduction of the forklift forks in the introduction openings covered by the bulges 12, the free width b of these introduction openings should be at least twice the width of conventional forklift forks.

The arch-shaped bulges 12 also have the advantage that the transport plate 10 during the

Lift of the forklift forks aligns itself in a horizontal direction when the forklift forks are brought into contact with the inner arches that approach each other. In the transition from the bulges 12 to the support sections 18, the plate 10 is also provided with a radius to reduce the bending tension in the edge.

As already mentioned above, the plate 10 has a perimeter edge 14 whose height R is approximately half that of the height h of the bulges 12. In addition to its effect of increasing stability, this edge also serves in some way for the lateral fixing of the stack of items on the transport plate 10.

From Figures 1 to 7 it can also be seen that the stiffening ribs 16 are designed in such a way that they are not taller than the vertices of the bulges 12. Furthermore, the wall thickness of the stiffening ribs 16 essentially corresponds to the wall thickness of the transport plate 10, such that during the production of the transport plate they can be configured as a single piece for example in the injection molding process.

Since the bulges 12 are configured in the thin transport plate 10, several transport plates 10 can be stacked on each other, as can be seen in Figure 8. This reduces the stack height of unused transport plates 10 .

Figures 9 and 10 show a transport plate according to a second embodiment, being provided, unlike the first embodiment, the stiffening ribs 16 not only locally respectively in the bulges 12, but extending to along the entire transport plate 10. Said more precisely, the transport plate 10 according to the second embodiment apart from the perimeter edge 14 has two stiffening ribs 16 located further in the interior and also perimetral. In addition, three stiffening ribs respectively have a path along the respective mediatrices, the same being cut in the center of the transport plate 10. The stiffening ribs 16 are provided, respectively, in the interstices of the bulges 12, of such that apart from the bulges 12 arranged in a grid form also the stiffening ribs 16 contribute to the increase in the stability of the plate 10 at those points where the bulges 12 are not provided. Since the stiffening ribs 16 are provided, respectively, in the interstices between two bulges 12 or the marginal sections, these stiffening ribs 16 also serve to make the height differences between the bulges 12 and the interstices smaller, since the items in bags to be stacked on the plate 10 they rest in the interstices area on the stiffening ribs on 16.

The lower side of the transport plate 10 of the second embodiment corresponds to that of the first embodiment, as can be seen in Figure 10.

Figures 11 and 12 show a transport plate 10 according to a third embodiment that differs from the first embodiment in that the transport plate 10 in the areas between the bulges 12, that is, in the area of the support sections 18, presents recesses 20 with circular shape. Therefore you can save weight. In addition, these recesses ensure that nothing can accumulate in the area between the bulges or between the bulges and the perimeter edge, such as rainwater, when transport plates are temporarily stored outdoors, or water when they are cleaned or materials that come from the article itself that has to be transported.

Figure 13 shows a transport plate 10 in accordance with a fourth embodiment that differs from the first embodiment in which in the intermediate areas between the bulges 12 and in the external areas are cassette-shaped projections 22. They also contribute to increasing the stability and stiffening of the plate 10. Similar to the second embodiment, the cassette-like projections 22 somehow fill the interstices between the bulges 12, further improving the surface load of the articles that have to be stacked on the plate 10 by the larger surfaces of the projections as a cassette. Under certain circumstances, thin stiffening ribs 16 can be nailed to the articles.

As can be seen in Figure 14, the protrusions 22 as a cassette are provided inside stiffening ribs 24 as a grid, whereby a particularly stable plate 10 is created.

A transport plate 10 not according to the invention is shown in Figures 15-17, which differs from the first embodiment in which, except for the perimeter edge 14, any type of geometry that reinforces the stability has been dispensed with .

Figure 18 shows a fifth embodiment in which two transport plates 10 according to the first embodiment have joined together in their respective support sections 18. Obviously, this solution duplicates, at the cost of the rotation of the items, the total height of this system. However, it is therefore possible that with the same transport plate on one side a stable means of transport is created, easy to lift with a flat forklift and, on the other hand, by joining two plates of the same construction, a pallet type of transport is created. The joining of both plates can be done by the manufacturer, for example,

by welding plastic or, if necessary, locally at the logistics company, for example by screws.

Figures 21 and 22 show a top perspective view or a bottom perspective view of a transport plate 10 according to a sixth embodiment. The thin-wall transport plate 10 itself is provided with multiple reinforcing geometries. The transport plate 10 is provided, in the area of the bulges 12, with multiple rectangular cavities 26 arranged longitudinally and transversely. From the bulges 12, two double wall stiffening ribs 28 are configured respectively on both sides. The outer edge 14 in the area between the bulges 12 is stretched upwards, such that between the outer edge 14 and the bulges 12, cuvette sections are formed in which at least part of the bags placed on the transport plate 10 and, therefore, cannot slide laterally from the transport plate 10. In the area of the lateral openings 30 of the bulges 12, the edge 14 is not stretched upwards, but downwards so as to On one side, also stiffen this particularly requested area, but also to design the transport plate as flat as possible. Therefore, cavities 26 are also used in the area of the bulges 12 and in the remaining zone stiffening ribs 28 as reinforcing geometries.

From the view shown in Figure 22, multiple reinforcement geometries can also be recognized. In addition, the transport plate 10 in the marginal zone has multiple support sections 18 divided by the reinforcement geometries and a support section 18 arranged centrally, relatively large, essentially squarely shaped.

In Figures 21 and 22 it can be recognized that in the case of the transport plate 10 it is a plate formed in itself that at any point has approximately the same material thickness and the bulges 12 as well as the reinforcement geometries are configured symmetrically and also slightly conically, such that multiple such transport plates 10 can be stacked on each other or completely nested and, therefore, can be stored with space saving or returned after delivery of the articles. Due to the nesting of the transport plates 10 with each other, these transport plates 10 can also be stacked very high without running the risk that the transport plates 10 with respect to each other slide or tip over and without having to fix or tie them with other auxiliary means.

Figures 23 and 24 show enlarged partial views of Figures 21 or 22. Figure 25 shows a partial cross-sectional view of the transport plate 10 in accordance with the sixth embodiment. From Figures 23 to 25 it can be recognized that each of the stiffening ribs that extends transversely and on both sides of each bulge 12 on its upper side has small cavities 29 and on its lower side protrusions

or nerves 31 configured as one piece. The latter are collected in the cavities 29 of another identical transport plate 10 when a transport plate 10 is placed on the other transport plate 10 (see Figure 26).

In Figure 26 it is shown that the projections 31 serve as separators and keep the transport plates 10 apart from one another in the vertical direction or in the direction of the stack, while the recesses 29 ensure that the projections 31 do not fall laterally by sliding or they slip when they come into contact with the surface of the stiffening ribs 28. Since the transport plates 10 essentially contact only the lower edges of the projections 31 or the cavities 29, the contact surface is minimized . Therefore, it is possible to prevent two or more plates 10 stacked on one another or nested with each other. The cavities 29 ensure, on the contrary, the stability of high piles of transport plates.

Both the cavities 29 and the ribs 31 are arranged symmetrically, in such a way that, on the one hand, the batteries remain in balance and do not tip over and, on the other hand, the plates 10 can be placed in a discretionary manner on each other and not they have to turn to a certain position first before stacking. Since, in addition, the projections 31 are arranged inside the double wall stiffening rib 28, they also do not increase the total height of an individual transport plate 10.

The transport plate according to the invention has been described above by means of different embodiments. Obviously, the invention is not limited to these embodiments, but can be modified within the scope of protection of the claims. Obviously, also individual elements or several elements of the different embodiments can be combined in a discretionary manner with each other. In this way, for example, notches for the reduction of the weight or for the exit of water in the transport plates of the second, fourth, fifth or sixth embodiment can be provided.

In addition, for example, grooves can be provided locally or along the entire transport plate. In the case of grooves, the surface load on the articles is less than in the case of nerves and, therefore, there is less risk of the articles acquiring, due to the nerves, pressure or even fingerprints being damaged.

In addition, the amount of stiffening ribs can be varied.

In addition, reinforcement elements can be arranged on the lower side.

Furthermore, more or less tunnel-shaped bulges may be provided. In this way, the plate can be provided only with a pair of bulges and stability in the transverse direction can be guaranteed exclusively through reinforcements, such as stiffening ribs. On the other hand, it is also conceivable to provide for more bulges than is necessary for the introduction of forklift forks, since

5 own bulges contribute to increase the bending resistance of the plate.

Instead of plastic, the transport plate can also be made of other suitable material. In addition, the transport plate can also be produced from different plastics with different material properties.

Finally, considering resistance points of view and depending on the case of application, also the shape of the

10 bulges may be designed differently, for example, in triangular or rectangular form, or different shapes may be combined with each other.
