Description

The invention relates to a pallet for the storage and transport of goods, with a top plate made of corrugated cardboard, a corrugated cardboard base plate and several arranged between the top plate and the bottom plate, made of cardboard, especially made of corrugated cardboard, support elements.

One is from the prior art Pallet known that a top plate and a bottom plate made of corrugated cardboard comprises between which are made of corrugated cardboard support elements. The support elements are as hollow bodies formed by means of glued to the inside of the hollow body, Flaps punched out of the lower plate are connected to the lower plate are. When manufacturing such pallets, a tool must be inserted into the hollow body be that the flaps in the direction of the support member and on the inside of the hollow body presses. The mounting space for fixing the flaps is due to the size of the cavity in the hollow body and its access openings limited and relatively small. The assembly of the known range is therefore not inconsiderable Associated effort.

The invention is therefore the object to provide a pallet of the type mentioned at the beginning, which is easier to assemble.

This task is done on a pallet of the generic type according to the invention solved that the support elements by means of connected to the top plate and / or the bottom plate Flaps are fixed laterally in the direction of the support element in the space between the top plate and the bottom plate are folded and on opposite outer side surfaces of the supporting member are set.

The pallet according to the invention has the advantage that too an enlarged assembly room during their manufacture for the lateral fixation of the support elements for disposal stands that a larger number different procedures allowed when fixing the flaps, since the flaps on outer side surfaces of the support elements be fixed. Two flaps can be swiveled towards each other and a support element between them take up. The range according to the invention is also distinguished due to the inclusion of the support element between two flaps in particular through improved stability across from horizontal forces from, for example, when moving the pallet along a floor area occur.

The flaps are preferably with the side surfaces of the support elements bonded.

To ensure the highest possible stability of the pallet achieve, it is convenient if two each with the top plate and / or two with the bottom plate connected flaps a support element record between them. So can from the lower plate two flaps in the space between the The top plate and the bottom plate must be folded in on opposite sides faces of the support element are fixed and thus take this between themselves. alternative and / or in addition can be provided that of the top plate two flaps in the space between the top plate and the lower plate are folded and on opposite one another faces of the support element fixed are.

A particularly high stability also opposite horizontal forces is in a preferred embodiment achieved in that the support elements faces have on which both one with the top plate and one with the flap connected to the lower plate is fixed.

Flaps can be removed from the top plate or the bottom plate is punched out and around a bending edge in the space be pivoted between the top plate and the bottom plate. additional can be provided that some Flaps as protruding from the lower plate or the upper plate and with this in one piece connected side tabs are formed around the longitudinal edge the top plate or the bottom plate in the space between the top plate and the bottom plate are swung in.

The flaps preferably cover each other a partial area of a side surface the support element, however, it can also be provided that at least some flaps a side face of the support element cover completely. In the coverage area can the flaps all over for example, be fixed to the support element by means of an adhesive.

The support elements are made of cardboard, for example made of solid cardboard. You can but also just like the top plate and the bottom plate made of corrugated cardboard be made. this makes possible a particularly simple recycling of the pallet according to the invention. A particularly high stability can the support elements be awarded by the fact that these of several layers of cardboard glued together, in particular Corrugated cardboard, which form a full body. Here can be provided that the individual cardboard layers are folded like an accordion. It is particularly advantageous however with regard to a high mechanical stability of the support elements, if the individual cardboard layers are cut and cut separately flat are glued together.

In a preferred embodiment are the individual layers of the support elements made of corrugated cardboard, whereby a particularly high stability is achieved that longitudinal direction the corrugations of the corrugated cardboard layers perpendicular to the plane of the top plate runs, because in the longitudinal direction the corrugated cardboard has a particularly high load-bearing capacity on.

In order to improve the stability of the pallet, according to a preferred embodiment the Pallet according to the invention provided that at least one support element is fixed with its top to the bottom of the top plate. It is particularly preferred if all the support elements of the pallet are fixed on the underside of the top plate. The support elements are preferably fixed to the underside of the top plate by means of an adhesive.

According to an advantageous embodiment provided that at least a support element is fixed with its underside to the top of the lower plate. All support elements are preferably the pallet with its underside at the top of the lower plate fixed. The fixation is preferably carried out using an adhesive.

To transport the pallet according to the invention by means of a transport vehicle, for example a pallet truck or a forklift, is according to one preferred embodiment provided that the support elements are arranged at a distance from each other and a space between them define for introduction the arms of the forklift or pallet truck.

To enable the transport of the pallet according to the invention with a pallet truck it may be necessary that the wheels of the pallet truck through the Reach through the bottom plate of the pallet. Therefore the lower plate points according to one preferred embodiment at least one opening through which the wheels a lift truck can pass through.

To prevent goods containers from slipping, in particular Corrugated cardboard boxes from the top of the top plate of the pallet of the invention To avoid, it is preferably provided that the top of the top plate has at least one area provided with an adhesive for gluing a container with the palette. Several areas on the top are preferred the top plate in which an adhesive is applied. So can for example four rectangular ones Adhesive areas can be provided in the corner areas of the Upper plate are arranged. Cheap it is when several adhesive areas are spaced apart are and form a series.

In the manufacture of the pallet according to the invention can be provided by default be that the Top of the top plate has at least one area in which an adhesive is applied. This adhesive area is preferred with a removable Release paper or a removable Release film covered so that the If necessary, remove the release paper or film from the Peel off the adhesive surface and a container can fix on the pallet.

Should the pallet according to the invention multiple or for different containers are used, it is advantageous if the pallet is a connecting element is assigned to solvable Connect the pallet with one placed on the top plate Container. This gives the opportunity the container while of the transport with the pallet, while it is then from this can be separated again.

Preferably, the connecting element comprises one fixing section fixable on the pallet and at least a pivoting wing element, which in a bottom opening a container can be inserted and placed on the inside of the container on the bottom surface is. This embodiment can be realized with little effort in terms of production technology therefore particularly inexpensive. To fix the attachment section by means of the above Adhesive areas to be glued to the top plate.

3 a plan view of a second embodiment of the pallet according to the invention, in which a container is fixed on the pallet by means of a second variant of the connecting element; and

4 : a sectional view along the line 4-4 in the 3 ,

In the 1 is a whole with the reference symbol 10 demonstrated first embodiment of the pallet according to the invention. It includes a rectangular base plate 12 as a base plate and a carrier plate 14 as the top plate, which has the same dimensions as the base plate 12 having. Between the base plate 12 and the carrier plate 14 are a total of nine supports 16 arranged as support elements. The pillars 16 are positioned in such a way that both the longitudinal and the transverse direction of the pallet 10 three rows aligned parallel to each other, each with three spaced supports 16 are formed, the adjacent rows in the transverse and longitudinal directions of the pallet 10 have identical distances. The pillars 16 are each from a variety of rectangular layers 18 made of corrugated cardboard, which are glued together. Any location 18 consists of so-called single-sided corrugated cardboard (corrugated cardboard) with a smooth paper or cardboard web onto which a corrugated paper is glued. The individual layers 18 the supports 16 are aligned with each other in such a way that the longitudinal direction of the corrugated cardboard corrugations is perpendicular to the plane of the carrier plate 14 runs and the layers 18 parallel to the longitudinal direction of the pallet 10 are aligned.

The pillars 16 are with their top on the bottom of the carrier plate 14 and with its underside at the top of the base plate 12 fixed with an adhesive. Already during the manufacture of the supports 16 becomes an adhesive on the top and bottom of it for sticking to the base plate 12 and the carrier plate 14 applied. The adhesive is initially for protection by means of a release paper 31 covered that when assembling the pallet 10 is simply peeled off to expose the adhesive. When assembling the pallet 10 is therefore a separate application of adhesive on the top and bottom of the supports 16 or on the corresponding areas of the base plate 12 and the carrier plate 14 not necessary anymore.

Any prop 16 is also by means of a first flap 24 and a second flap 26 that on opposite side faces 27 . 29 the supports 16 are fixed in an upper edge area by means of an adhesive with the carrier plate 14 connected. The flaps 24 . 26 are by U-shaped punchings from the carrier plate 14 divided or on the longitudinal edges of the support plate 14 articulated and along a bending edge in the direction of the supports 16 in the space between the base plate 12 and the carrier plate 14 collapsed.

Furthermore, the supports 16 by means of a third flap 28 and a fourth hatch 30 with the base plate 12 connected, the flaps 28 . 30 also on the opposite side faces 27 and 29 the supports 16 are fixed, in a lower edge area. The flaps 28 . 30 are by U-shaped punched holes from the base plate 12 divided or on the longitudinal edges of the base plate 12 articulated and along a bending edge in the direction of the supports 16 in the space between the base plate 12 and the carrier plate 14 collapsed. First and second flaps 24 respectively. 26 as well as a third and a fourth flap 28 respectively. 30 so take a prop 16 between them and fix them.

The flaps on the longitudinal edges of the carrier plate 14 and stand plate 12 overlap the corresponding side surfaces of the supports 16 in their longitudinal direction completely, while that from the surface of the plates 12 . 14 stamped flaps only cover a central area of the corresponding side surfaces. In the direction of the vertical expansion of the supports 16 overlap the flaps 24 . 26 . 28 . 30 one third each of the side surfaces.

Between adjacent rows of supports 16 are two openings each 32 in the stand plate 12 introduced through which, for example, the wheels of a lift truck can reach, the support arms between the rows of supports 16 in the longitudinal or transverse direction of the pallet 10 can be retracted.

On the top of the carrier plate 14 are by marker angles 36 rectangular areas 38 marked, in which an adhesive can be applied, for example to fix a container for receiving goods there and thus prevent it from slipping off the pallet 10 to secure. The areas 38 lie on the supports 16 across from. If the areas 38 are provided with an adhesive, they can be covered with a release paper or a release film, which can be removed if necessary, as already in connection with the supports 16 and the release paper 31 was explained.

In the in the 1 and 2 embodiment shown is on the top of the support plate 14 along the center line of the pallet 10 a connecting element 40 arranged to create a detachable connection between the pallet 10 and one on the carrier plate 14 attached container 46 to enable. The connecting element 40 is a blank made of corrugated cardboard with a central fastening section 41 and with these laterally projecting first and second wing elements 42 . 43 related to the mounting section 41 in each case one parallel to the longitudinal edges of the pallet 10 aligned bending edge are pivotable. The fastening section 41 is in the illustrated embodiment over three areas provided with adhesive 38 on the carrier plate 14 fixed. Alternatively, for example, a single one could cover practically the entire length of the carrier plate 14 extending, central adhesive area are used. The container 46 includes a floor 47 with a slit 48 , The wing elements initially swung up 42 . 43 can through the slot 48 in the in 2 shown dashed arrangement in the container 46 inserted and then in the direction of the corresponding longitudinal edge of the carrier plate 14 can be folded outwards so that they then hit the floor 47 of the container 46 cover like this in 2 is shown in a solid line. In this arrangement the container is consequently 46 firmly with the top of the carrier plate 14 connected. To the connection between the container 46 and the palette 10 to solve the wing elements 42 . 43 in by the dashed lines in 2 position shown folded up, and the container 46 can then be off the pallet 10 be lifted off.

To the two wing elements 42 . 43 to keep in a vertical arrangement and thus the placement and removal of the container 46 to simplify are the wing elements 42 . 43 in the area of its free longitudinal edge with a trapezoidal punched-out 58 . 60 provided, which are arranged in mirror image to each other. They can be pressed together in such a way that the widened head part of the cut-out 60 the die cut 58 reaches through and easily detachable in the punched-out punch 58 is locked by their boundary edges.

In the 3 and 4 is a second embodiment 65 the inventive pallet shown, in which a container 70 by means of a clip 72 trained connecting elements with the carrier plate 14 is detachably connected. The palette 65 is different from the palette 10 in that in this between the adjacent supports 16 two rectangular openings in the middle row 74 in the carrier plate 14 are let in. These openings 74 align with openings 76 same dimensions in the floor 78 of the container 70 , and through the overlapping openings 74 . 76 are cliffs 72 which plugged the floor 78 of the container 70 and the carrier plate 14 ent along the opposite long sides of the openings 74 . 76 reach around and brace.

A cross section through a clip 72 that has an overlap area from the floor 78 and the carrier plate 14 in the edge area around the openings 74 . 76 embraces is in 4 shown. The clip 72 is made of plastic and has a rectangular frame 80 on the the openings 76 and 74 reaches through and at its upper end by an outward pointing, inside on the floor 78 of the container 70 overlying projection 82 is edged.

On one longitudinal edge of the projection 82 is by means of a connecting section 83 a lid 84 hinged. The lid 84 is at its connecting section 83 opposite longitudinal edge with a tongue 86 with a safety opening 88 provided in the one on top of the tab 82 arranged safety hook 90 to secure the lid 84 intervenes.

On the inner long sides of the frame 80 is an L-shaped angle element 92 . 94 with one long leg each 98 . 102 and with a short leg 100 . 104 hinged. At the bottom of the lid 84 are two holding elements 106 arranged which between the short legs 100 . 104 are pressed in and press them down so that the short legs 100 . 104 parallel to the long sides of the frame 80 align. This brings the long legs 98 . 102 on the underside of the carrier plate 14 to the system so that the carrier plate 14 and the floor 78 in the edge area around the openings 74 . 76 along the long sides of the framing 80 from the bottom of the tab 82 , from the outside of the frame 80 and from the long leg 98 . 102 be embraced.

To the connection between the container 70 and the carrier plate 14 to solve, must first in the fuse opening 88 safety hooks 90 from the tongue 86 be solved. Then the lid can 84 from the lead 82 be lifted off. By lifting the lid 84 between the short legs 100 . 104 pressed-in holding elements 106 removed from these, so that the angular elements 92 . 94 due to the restoring force of the plastic material now take a position in which the free ends of the long legs 98 . 102 behind the flight of the outer side surface of the framing 78 step back, which loosens the grip and the clip 72 the openings 74 . 76 can be removed.
