Description

[0001] The invention relates to a pallet, in particular for the transport of goods, as well as a runner for a pallet, a sandwich block for producing a layer of a pallet, and a method for producing a pallet.

[0002] Transport pallets according to EN 13698-1 and UIC 435-2 (Europool pallets) are known from the state of the art. These have three base boards, each connected by three blocks to three cross boards, on which five deck boards are arranged. The corresponding boards are made of solid wood.

[0003] A disadvantage of solid wood pallets is their relatively high weight (depending on the wood moisture content, 20 to 24 kg for dimensions of 1200 x 800 x 144 mm).

[0004] Pallets are also known that have cover plates and an intermediate layer, with the intermediate layer / stiffeners having a honeycomb structure (US 2,544,657). Such pallets can have recesses. US 2,544,657 describes cover plates made of metal and stiffeners made of paper.

[0005] US 3,200,489 describes the production of a honeycomb structure made of metal, in particular the folding and joining of tube segments under the influence of heat.

[0006] US 2015 / 174 881 A1 describes that a honeycomb structure layer can be cut from a honeycomb structure block and that the panels from which the honeycombs are made are made of, for example, paper or foil.

[0007] This gives rise to the task of providing a pallet that has a reduced weight compared to the state of the art while maintaining the same stability.

[0008] This object is achieved by the pallet according to the invention according to claim 1, the runner according to the invention according to claim 10, the sandwich block according to the invention according to claim 11, and the method according to the invention according to claim 13. Specific embodiments of the pallet are specified in subclaims 2 to 9, specific embodiments of the sandwich block are specified in subclaim 12, and specific embodiments of the method are specified in subclaim 14. The embodiments are described below.

[0009] A first aspect of the invention relates to a pallet comprising a base body which has at least the following components: a first plate and a second plate arranged parallel to the first plate, wherein the first plate and the second plate each extend in the direction of a pallet width and a pallet depth, wherein the pallet has a pallet height running perpendicular to the pallet width and the pallet depth, a layer arranged between the first plate and the second plate, which layer has a plurality of tube segments, wherein the tube segments each have two cut ends which delimit the tube segments in the circumferential direction, and wherein the tube segments each have a segment depth, a segment width and a segment height, wherein the segment depth corresponds to the maximum extension of the tube segment in the longitudinal direction,and wherein the segment width corresponds to the maximum extension of the pipe segment along an (imaginary) connecting line between the cut ends perpendicular to the longitudinal extension direction (i.e. in the cross-section of the pipe segment), and wherein the segment height corresponds to the maximum extension perpendicular to the segment depth and the segment width, and wherein the pipe segments are arranged in the layer such that the segment depth runs in the direction of the pallet height, the segment width runs in the direction of the pallet width and the segment height runs in the direction of the pallet depth, wherein the layer has at least one recess continuous in the direction of the pallet height, and wherein the first plate has at least one first opening which at least partially overlaps with the at least one recess.

[0010] This means in particular that the at least one first opening has the same dimensions as the at least one recess, wherein the at least one first opening is aligned with the at least one recess, or that the at least one first opening is smaller than the at least one recess, wherein a part of the at least one recess is aligned with the at least one first opening.

[0011] The layer has a plurality of rows of pipe segments running in the direction of the pallet width, wherein in particular adjacent pipe segments within the rows are mechanically connected, wherein the layer has at least one first row of pipe segments running in the direction of the pallet width, at least one second row of pipe segments running in the direction of the pallet width and at least one strip, wherein the pipe segments of the at least one first row and the pipe segments of the at least one second row are mechanically connected via the at least one strip, wherein in particular the pipe segments of the at least one first row are mechanically connected by means of their cut ends to a first strip side of the at least one strip, and wherein the pipe segments of the at least one second row are mechanically connected by means of their cut ends to a second strip side of the at least one strip opposite the first strip side.The first plate, the second plate and / or the pipe segments comprise a wood material or are formed from a wood material.

[0012] A first sub-aspect of the first aspect of the invention relates to a pallet comprising a base body which has at least the following components: a first plate and a second plate arranged parallel to the first plate, wherein the first plate and the second plate each extend in the direction of a pallet width and a pallet depth, wherein the pallet has a pallet height running perpendicular to the pallet width and the pallet depth, a layer arranged between the first plate and the second plate, which layer has a plurality of tube segments, wherein the tube segments each have two cut ends which delimit the tube segments in the circumferential direction, and wherein the tube segments each have a segment depth, a segment width and a segment height, wherein the segment depth corresponds to the maximum extension of the tube segment in the longitudinal direction,and wherein the segment width corresponds to the maximum extension of the pipe segment along an (imaginary) connecting line between the cut ends perpendicular to the longitudinal extension direction (i.e., in the cross-section of the pipe segment), and wherein the segment height corresponds to the maximum extension perpendicular to the segment depth and the segment width, and wherein the pipe segments are arranged in the layer such that the segment depth runs in the direction of the pallet height, the segment width runs in the direction of the pallet width, and the segment height runs in the direction of the pallet depth, wherein the layer has at least one recess that is continuous in the direction of the pallet height, wherein the at least one recess has an extension in the direction of the pallet width that corresponds at least to the segment width and has an extension in the direction of the pallet depth that corresponds at least to the segment height, and wherein the first plate has at least one first opening,which at least partially overlaps with the at least one recess. ,

[0013] A second sub-aspect of the first aspect of the invention relates to a pallet comprising a base body which has at least the following components: a first plate and a second plate arranged parallel to the first plate, wherein the first plate and the second plate each extend in the direction of a pallet width and a pallet depth, wherein the pallet has a pallet height running perpendicular to the pallet width and the pallet depth, a layer arranged between the first plate and the second plate, which layer has a plurality of tube segments, wherein the tube segments each have two cut ends which delimit the tube segments in the circumferential direction, and wherein the tube segments each have a segment depth, a segment width and a segment height, wherein the segment depth corresponds to the maximum extension of the tube segment in the longitudinal direction,and wherein the segment width corresponds to the maximum extension of the pipe segment along an (imaginary) connecting line between the cut ends perpendicular to the longitudinal extension direction (i.e., in the cross-section of the pipe segment), and wherein the segment height corresponds to the maximum extension perpendicular to the segment depth and the segment width, and wherein the pipe segments are arranged in the layer such that the segment depth runs in the direction of the pallet height, the segment width runs in the direction of the pallet width, and the segment height runs in the direction of the pallet depth, wherein the layer has at least one recess that is continuous in the direction of the pallet height, wherein the at least one recess has an extension in the direction of the pallet width that is less than the segment width and has an extension in the direction of the pallet depth that is less than the segment height, and wherein the first plate has at least one first opening,which at least partially overlaps with the at least one recess. ,

[0014] The pallet according to the invention is characterized by its very low weight and high mechanical stability, particularly due to the wood materials used and the hollow spaces in the layer. Furthermore, additional components, such as pallet feet, can advantageously be inserted into the recesses.

[0015] In the context of the present invention, the term "pipe segment" refers to a part of a real or imaginary pipe with a longitudinal direction. The cross-section of the pipe perpendicular to its longitudinal direction has a circumference, i.e., an imaginary line that delimits the cross-section on its outer side. The cross-section is not necessarily circular, but can also be angular or elliptical. The circumferential direction of the pipe (even in the case of a pipe with a angular cross-section) runs along an imaginary circle that surrounds the cross-section of the pipe perpendicular to the longitudinal direction.

[0016] The pipe segments each have a wall which is bounded in the circumferential direction by the cutting edges, the wall being open in the circumferential direction. The wall is continuously open in the longitudinal extension direction. Here, the circumferential direction of the pipe segment is meant to be the circumferential direction of the associated actual or imaginary pipe which has a closed wall. The pipe segment can in particular be formed by cutting the pipe, but can also be formed in other ways, in particular by mechanically connecting several strips or by an extrusion process.

[0017] The cutting ends of the pipe segment limit the pipe segment in the circumferential direction. Thus, the wall of the pipe segment is limited in the circumferential direction by the cutting ends. The cross-section of the pipe segment is thus formed by an open profile. The open profile can in particular be shaped like a circular segment, for example semi-circular, U-shaped or V-shaped.

[0018] The pipe segments each further have two cutting surfaces that limit the pipe segments in the longitudinal extension direction. The cutting surfaces in particular run perpendicular to the longitudinal extension direction.

[0019] According to an embodiment, the pipe segments are each connected to the first plate with one of the cutting surfaces and / or mechanically connected to the second plate with the other cutting surface.

[0020] In a further embodiment, the pipe segments are arranged perpendicular to the first plate and the second plate with respect to their longitudinal extension direction.

[0021] The connecting line between the cutting ends runs in particular along the common direction of the cutting ends, in particular in cross-section with respect to the longitudinal extension direction of the pipe segment. In cases where the cutting ends do not run parallel to each other in cross-section, the connecting line between the points of the cutting surfaces with the greatest extension in the circumferential direction is defined.

[0022] The pipe segments each form a cavity that is bounded by the inner surface of the wall. Here, the segment width (i.e., the outer width of the pipe segment) corresponds to the sum of the maximum extent of the cavity in the direction of the connecting line between the cutting ends perpendicular to the longitudinal extension direction (i.e., in the cross-section) and twice the wall thickness. The segment height corresponds to the sum of the maximum extent of the cavity perpendicular to the segment width and the wall thickness.

[0023] In the context of the present invention, the term 'recess' can therefore refer to either the cavity formed by the interior of the pipe segments or a gap between two adjacent pipe segments of the layer. As described above, the extent of the cavity inside the pipe segments is twice the wall thickness smaller than the segment width and one wall thickness smaller than the segment height, thus constituting a recess within the meaning of the invention.

[0024] The at least one recess has an extension in the direction of the pallet width and an extension in the direction of the pallet depth. If the at least one recess has a shape in which the extension in the direction of the pallet width or the pallet depth is not constant, the term 'extension of the recess' in the context of the present invention refers to the minimum extension in the respective direction.

[0025] According to one embodiment of the pallet, the at least one recess has an extension in the direction of the pallet width that corresponds at least to the segment width and the at least one recess has an extension in the direction of the pallet depth that corresponds at least to the segment height.

[0026] In this case, the corresponding cavities inside the pipe segments are smaller than the recess in both directions (along the pallet width and the pallet depth). A recess is created, in particular, by omitting pipe segments at certain positions in the layer.

[0027] According to a further embodiment, the at least one recess has an extension in the direction of the pallet width which is less than the segment width and the at least one recess has an extension in the direction of the pallet depth which is less than the segment height.

[0028] In this case, in particular, the cavities inside the pipe segments also form recesses within the meaning of the invention, into which, for example, a foot of the pallet can be inserted.

[0029] According to a further embodiment, the at least one recess has an extension in the direction of the pallet width which corresponds to at least twice the segment width.

[0030] According to a further embodiment, the at least one recess has an extension in the direction of the pallet depth which corresponds to at least twice the segment height.

[0031] According to a further embodiment, the extension of the recess in the direction of the pallet width is at least 50 mm, wherein the extension in the direction of the pallet depth is at least 30 mm.

[0032] The recess is therefore large enough to accommodate a foot.

[0033] The at least one first opening of the first plate has an extension in the direction of the pallet width and an extension in the direction of the pallet depth. According to one embodiment, the at least one first opening has a rectangular shape. In the event that the at least one first opening has a shape in which the extension in the direction of the pallet width or the pallet depth is not constant, the term 'extension of the first opening' in the context of the present invention refers to the minimum extension in the respective direction.

[0034] According to one embodiment, the pallet comprises a wood-based material or is formed from a wood-based material. The first plate, the second plate, and / or the tube segments comprise a wood-based material or are formed from a wood-based material. According to one embodiment, the tube segments comprise a wood-based material or are formed from a wood-based material. According to another embodiment, the first plate and / or the second plate comprise a wood-based material.

[0035] According to a further embodiment, the first plate and / or the second plate is formed from a wood material.

[0036] In the context of the present invention, the term "wood-based material" refers to a material comprising comminuted wood, in particular wood shavings, wood chips, wood veneers, wood veneer strips, wood wool, wood fibers or wood dust, or other lignocellulosic materials. Furthermore, the wood-based material may, in particular, comprise binders, adhesives, and / or additives. Additives may, in particular, be hydrophobizing agents, wood preservatives, flame retardants, hardeners, or color particles. Binders include, in particular, urea glue, synthetic resins, e.g., phenolic resins, isocyanates, plastics, and / or bioplastics. Wood veneers and / or wood veneer strips are used, in particular, for the production of plywood and / or particleboard (oriented strand board).

[0037] Wood materials include in particular solid wood materials, e.g. solid wood panels (according to DIN EN 12775) or glued wood panels, cross laminated timber, glued laminated timber, block laminated timber, and / or laminated wood, veneered wood materials, e.g. veneer plywood (FU), laminated veneer lumber, strip veneer lumber, bending plywood, wood particle materials, e.g. flat pressed boards (P2), extruded boards, chipboard moldings, coarse particle boards (OSB boards, according to DIN EN 300) and / or strip veneer lumber (LSL), wood fiber materials, e.g. wood fiber insulation boards (HFD), porous fiberboards, soft boards (SB), medium-hard fiberboards (MB), hard fiberboards (HB or HFH), hard fiberboards, extra-hard fiberboards (HFE), medium-density fiberboards (MDF), high-density fiberboards ( high-density fiberboards, HDF) and / or ultra-lightweight fiberboards (ULDF), Arboform or liquid wood.

[0038] The term "fiberboard" refers to the wood-based materials specified in DIN EN 622. The term "particleboard" refers to the wood-based materials specified in the standards DIN EN 309 and DIN EN 312. The term "plywood" refers to the wood-based materials specified in the standards DIN 68708 and DIN EN 313.

[0039] As a basic material for shell and interior construction, wood-based materials have the advantage of great material strength and mechanical resilience while being lightweight.

[0040] According to one embodiment, the wood-based material has a lignin content of >5%, in particular >10% by weight. This means that paper and cardboard, in particular, do not constitute wood-based materials within the meaning of the present invention, since the lignin of the wood raw materials used is largely removed during paper production, e.g., by chemical bleaching agents.

[0041] According to a further embodiment, the wood material is free of chemical bleaching agents.

[0042] According to another embodiment, the wood-based material is manufactured using a dry process with a wood moisture content of <20%. The percentage refers to the ratio of the water weight to the absolutely dry wood mass. In a dry process, the wood particles are dried before floss formation and pressing, and the product has a wood moisture content of less than 20%. The glue can be applied before or after drying.

[0043] According to a further embodiment, the wood-based material comprises wood fibers compressed under pressure and / or heat. According to a further embodiment, the wood-based material has a density of > 800 kg / m 3 . High-density fiberboards, for example, have a density in this range.

[0044] According to a further embodiment, the pipe segments are made of a high-density fiberboard (HDF) material. High-density fiberboard (HDF) exhibits particularly high strength.

[0045] According to a further embodiment, the pipe segments are formed from a plurality of strips. The strips extend in the longitudinal direction of the pipe segment. In this embodiment, a pipe segment with a square cross-section is formed.

[0046] According to one embodiment, the strips comprise a wood material or are formed from a wood material.

[0047] According to one embodiment, the pipe segments are made of pressed wood, in particular pressed wood fibers or wood chips. For example, the pipe segments can be manufactured by cutting pipes from pressed wood. Such a pipe can be manufactured, for example, by pressing a wood mass comprising shredded wood, in particular wood fibers or wood chips, into a press-molding channel with a tubular recess and curing the wood mass. Alternatively, a half-pipe or pipe segment can also be manufactured directly by pressing a wood mass, in particular in a press-molding channel with a tubular segment-shaped recess or using a flat pressing tool with a suitable contour.

[0048] According to a further embodiment, the wood-based material is produced from a wood mass, in particular a dendromass, by means of an extrusion process.

[0049] The use of pressed wood allows for the cost-effective production of pipes or pipe segments of almost any shape and dimension, whereby a very uniform dimensioning of the pipes or pipe segments can be achieved compared to natural products.

[0050] According to a further embodiment, the pipe segments have a square cross-section, in particular an octagonal segment-shaped cross-section.

[0051] By means of tube segments with an octagonal segment-shaped cross-section, a particularly advantageous force distribution is achieved when forces are exerted on the base body of the pallet according to the invention, which results in increased mechanical stability of the pallet.

[0052] According to a further embodiment, the pipe segments have a U-shaped cross-section.

[0053] According to a further embodiment, the pipe segments have a trapezoidal cross-section.

[0054] A trapezoidal cross-section has the advantage of being particularly easy to manufacture while at the same time offering good stability properties.

[0055] According to a further embodiment, the pipe segments are formed from a U-shaped or trapezoidal segment-shaped folded plate, in particular an HDF plate.

[0056] The pipe segments are formed in particular by milling V-shaped mitres in the plate, folding the plate at the mitres and gluing at the mitres.

[0057] According to a further embodiment, all pipe segments of the layer have substantially a uniform segment depth.

[0058] According to a further embodiment, all pipe segments of the layer have a substantially uniform segment width.

[0059] According to a further embodiment, all pipe segments of the layer have substantially a uniform segment height.

[0060] According to a further embodiment, the at least one recess is completely surrounded by pipe segments in the direction of the pallet width and the pallet depth.

[0061] The layer comprises several rows of pipe segments running in the direction of the pallet width, with adjacent pipe segments within the rows being mechanically connected.

[0062] By mechanically connecting adjacent tube segments, the mechanical stability of the pallet is advantageously increased.

[0063] According to a further embodiment, the layer comprises at least one first row of pipe segments extending in the direction of the pallet width and at least one second row of pipe segments extending in the direction of the pallet width.

[0064] The layer has at least one first row of pipe segments running in the direction of the pallet width, at least one second row of pipe segments running in the direction of the pallet width and at least one strip, wherein the pipe segments of the at least one first row and the pipe segments of the at least one second row are mechanically connected via the at least one strip, wherein in particular the pipe segments of the at least one first row are mechanically connected by means of their cut ends to a first strip side of the at least one strip, and wherein the pipe segments of the at least one second row are mechanically connected by means of their cut ends to a second strip side of the at least one strip opposite the first strip side.

[0065] Such strips mechanically connect and thus stabilize the tube segments of two rows, which increases the mechanical stability of the base body of the pallet.

[0066] According to a further embodiment, the second plate has at least one second opening which at least partially overlaps with the at least one recess.

[0067] This means in particular that the at least one second opening has the same dimensions as the at least one recess, wherein the at least one second opening is aligned with the at least one recess, or that the at least one second opening is smaller than the at least one recess, wherein a part of the at least one recess is aligned with the at least one second opening.

[0068] According to a further embodiment, the second plate has at least one second opening which at least partially overlaps with the at least one recess, wherein the at least one second opening has a smaller extension in the direction of the pallet depth or in the direction of the pallet width, in particular in the direction of the pallet depth, than the at least one first recess with which the at least one second opening overlaps.

[0069] The at least one second opening of the second plate has an extension in the direction of the pallet width and an extension in the direction of the pallet depth. According to one embodiment, the at least one second opening has a rectangular shape. In the event that the at least one second opening has a shape in which the extension in the direction of the pallet width or the pallet depth is not constant, the term 'extension of the second opening' in the context of the present invention refers to the minimum extension in the respective direction.

[0070] According to a further embodiment, the at least one second opening has a smaller extension in the direction of the pallet depth than the corresponding at least one recess with which the at least one second opening overlaps.

[0071] According to a further embodiment, the at least one second opening has a smaller extension in the direction of the pallet width than the corresponding at least one recess with which the at least one second opening overlaps.

[0072] Such at least one second opening is arranged on the side of the pallet opposite the feet or runners (i.e., the top side). Such openings advantageously allow multiple pallets to be stacked in a stable and space-saving manner by inserting the feet of another pallet according to the invention into the second openings.

[0073] Due to the smaller extension of the second opening in the direction of the pallet depth or pallet width, at least one additional space is created between the second plate and the adjacent tube segments of the pallet layer. This has the advantage that an additional component of the pallet, e.g., a foot or a block of a skid, can be arranged, in particular wedged, in said additional space. This allows, in particular, a particularly simple mechanical connection between the additional component and the base body of the pallet.

[0074] According to a further embodiment, the pallet further comprises at least one foot mechanically connected to the base body, in particular according to the second aspect of the invention.

[0075] According to a further embodiment, the at least one foot is formed from a wood material.

[0076] A pallet according to the invention can be advantageously stored on such feet. Furthermore, with appropriate spacing between the feet, the pallet according to the invention can be used as a four-way pallet and, in particular, can be picked up by a forklift.

[0077] According to a further embodiment, the at least one foot, in particular for mechanically connecting the foot to the base body, is arranged at least partially in the at least one recess.

[0078] According to a further embodiment, the at least one foot has at least two support elements, in particular exactly two support elements, for mechanically connecting the at least one foot to the base body and at least one connecting element, in particular exactly one connecting element, wherein the at least two support elements are mechanically connected by means of the at least one connecting element, in particular each on a first side.

[0079] The aforementioned mechanical connection of the foot to the base body can be achieved, for example, by clamping or wedging the foot, especially the support elements, into the respective recess of the layer. Optionally, the foot can also be glued to components of the base body of the pallet.

[0080] According to a further embodiment, the at least two support elements and the at least one connecting element are each formed from a board made of a wood-based material, e.g., an HDF board. In particular, the at least two support elements and the at least one connecting element are formed from a single board, wherein the board has miters on the connecting surfaces (in particular first sides) between the at least two support elements and the at least one connecting element.

[0081] According to a further embodiment, the at least two support elements have a base area with a first side and a second side arranged parallel to the first side, wherein the at least two support elements are each mechanically connected via their first side to the at least one connecting element, and wherein the length of the first side represents the minimum extension of the respective support element in the direction of the respective first side, and wherein the length of the second side represents the maximum extension of the respective support element in the direction of the respective second side.

[0082] In particular, the first and second sides have different lengths. The base area is limited by the first and second sides.

[0083] The support element thus becomes narrower from the second side to the first side. The connecting element of the at least one foot forms the support surface on the ground when the at least one foot is connected to the base body of the pallet and the pallet stands on the at least one foot. Such an arrangement has the advantage that pallets equipped with such feet are easily stackable, with the feet of a first pallet being insertable into the second openings of the second plate of a second pallet when the first pallet is stacked on top of the second pallet.

[0084] According to one embodiment of the foot, the at least two support elements have a trapezoidal base.

[0085] According to a further embodiment of the foot, the at least two support elements have a base in the shape of an isosceles trapezoid.

[0086] A trapezoidal shape represents the simplest form of a support element described above. In this case, the first and second sides of the base are connected by two straight additional sides.

[0087] According to a further embodiment, the at least one connecting element has a rectangular base area.

[0088] According to a further embodiment, the at least two support elements can be rotated or folded relative to the at least one connecting element about the respective first side of the respective support element, such that an angle between the plane of extension of the respective support element and the at least one connecting element can be changed, in particular such that when the angle is reduced within a certain angular range, mechanical stress is created between the respective support element and the at least one connecting element. This is possible, for example, if the respective support element and the at least one connecting element are made from a board, e.g., an HDF board, and are connected to one another at a correspondingly designed miter.

[0089] According to a further embodiment, the second sides of the at least two support elements are mechanically connected to the second plate of the base body.

[0090] According to a further embodiment, the second sides of the at least two support elements are arranged in the direction of the pallet width, wherein the second sides each have a length that corresponds at most to the maximum extension, in particular substantially to the maximum extension, of the at least one second opening of the second plate in the direction of the pallet width. With this arrangement, it is advantageously possible to insert the at least one foot through the at least one second opening into the at least one recess of the layer.

[0091] According to a further embodiment, the extension in the direction of the pallet depth of the at least one second opening is less than the extension in the direction of the pallet depth of the at least one recess of the layer overlapping the at least one second opening. As a result, spaces are formed between the second plate and the pipe segments surrounding the corresponding recess or the inner surfaces of the wall of the pipe segment forming the recess, into which spaces, in particular, the support elements of a foot according to the invention can be introduced.

[0092] According to a further embodiment, the second sides of the at least two connecting elements are arranged in the direction of the pallet depth, wherein the second sides each have a length which corresponds at most to the extension, in particular substantially to the extension, of the at least one second opening of the second plate in the direction of the pallet depth.

[0093] According to a further embodiment, the extension in the direction of the pallet width of the at least one second opening is smaller than the extension in the direction of the pallet width of the at least one recess of the layer overlapping with the at least one second opening.

[0094] If, when the at least one foot is inserted through the at least one first opening, the foot is designed in such a way that the at least two support elements are foldable or collapsible around the at least one connecting element, and the at least one foot is inserted through the at least one second opening into the at least one recess, the foot opens after passing through the at least one second opening with an increase in said angle and the support elements are displaced in the direction of the pallet depth (in the event that the second sides of the support elements are arranged in the direction of the pallet width) or pallet width (in the event that the second sides of the support elements are arranged in the direction of the pallet depth).

[0095] If the extent of the at least one second opening in the direction of the pallet depth or pallet width is less than the extent of the corresponding at least one recess that overlaps with the corresponding at least one second opening, the support elements each enter a corresponding space formed by the second plate and the pipe segments surrounding the at least one recess. In particular, with a corresponding design of the at least one foot and the at least one recess, a mechanical tension prevails in the state in which the support elements are introduced into the at least one recess, through which mechanical tension the support elements exert a force on the second plate and the adjacent pipe segments, or the inner surfaces of the wall of the pipe segment forming the recess, which force advantageously promotes a firm mechanical connection of the at least one foot to the base body.

[0096] Alternatively, the at least one first opening and the at least one second opening can also have the same extension in the direction of the pallet width. With appropriate dimensions of the foot, sufficient mechanical anchoring of the foot is also ensured in this case.

[0097] According to a further embodiment, the extension in the direction of the pallet width of the at least one first opening of the first plate is less than the extension of the corresponding at least one recess with which the at least one first opening overlaps, wherein in particular the said extension of the at least one first opening is designed such that the at least two support elements of the at least one foot rest against the boundary of the at least one first opening when the at least one foot is introduced into the corresponding at least one recess.

[0098] According to a further embodiment, the extension of the at least one first opening of the first plate in the direction of the pallet depth is less than the extension of the corresponding at least one recess with which the at least one first opening overlaps, wherein in particular the said extension of the at least one first opening is designed such that the at least two support elements of the at least one foot rest on the boundary of the at least one first opening when the at least one foot is introduced into the corresponding at least one recess.

[0099] The latter two embodiments have the advantage of enabling a more stable mechanical connection between the base body and the at least one foot. Furthermore, due to the mechanical connection to the first plate, the at least one foot cannot slip out of the at least one recess through the first opening. This locking is achieved in particular by the at least two support elements that widen from the first side to the second side.

[0100] Alternatively, the at least one first opening and the at least one second opening can also have the same extension in the direction of the pallet depth. With appropriate dimensions of the base, sufficient mechanical anchoring of the base is also ensured in this case.

[0101] According to a further embodiment, the pallet has at least one runner mechanically connected to the base body, in particular according to the third aspect of the invention.
