Pallet with sides made of tubular and / or wire grid frames

The invention relates to a pallet with a tubular and / or wire mesh frame that protrudes from the base Side walls that can be individually folded down against the floor body.

Pallets are transport platforms on which piece goods are put together to form a loading unit in order to rationalize the handling of goods between different modes of transport (railroad, ship, TjKW, airplane). Various forms of pallet are already known, namely the so-called flat pallet, which only consists of consists of a bottom body forming the transport platform, the box pallets, which with protruding from the bottom body, closed side walls are provided, and the mesh box pallets, the side walls of which by Eohr- and / or wire mesh frame are formed.

While the flat pallets serve as transport platforms for stacked goods, box pallets are used to accommodate Bulk goods or small parts used. Wire-mesh box pallets are ultimately used where bulky ones are not Stackable and unpackaged goods must be protected against damage during transport.

If pallets are transported as empties, the flat pallets are particularly advantageous to stow because they can be easily stacked with little space requirement and thus cause low transport costs.

Box pallets and lattice box pallets can also be stacked on top of one another as empties. They do, however, require naturally a much larger storage space with the result that higher return transport costs arise for the user.

In order to eliminate this disadvantage, it has already become known to be used in connection with the so-called international pool pallets made of wood, which, for example, are designed as tubular and / or lattice frames and can be placed as side walls.

When transporting empties, these stacking frames are used in the space-saving Flat format placed loosely on the wooden pallet, which means that it is hardly possible to put several of these together Stack units securely on top of each other. It would be conceivable that the pipe or pipe resting on the wooden pallets Lattice frames, for example, to be lashed using tensioning straps, however this would little improve the stackability of the unit.

In recognition of these disadvantages, lattice box pallets are also already available have been created in which the side walls designed as tubular and / or lattice frame constructions can be folded are attached to the floor body so that they are easily folded against the floor body for the transport of empties can be. In this case it is possible to have several collapsed Units can be safely stacked immovably on top of one another, because this is in contrast to the flat wooden pallets So-called catch corners on the bottom bodies protrude beyond the side wall stack from the bottom body.

Such lattice box pallets, however, have the defect that they are not, like the international pool pallets made of wood, can be used as a normal flat pallet. The purpose of the invention is to adhere to all the known types of pallets Eliminate disadvantages and combine their advantages. The invention is therefore based on the object

to create a pallet of the type described above, both as a flat pallet without any side walls can be used, as well as in connection with tubular and / or wire mesh frames as a mesh box pallet can be taken. When used as a lattice box pallet or in conjunction with full-surface side walls As a collapsible container, the side walls should remain in connection with the base body for the transport of empties and can be folded down against this to save trees. Furthermore, several units should be used both with erect Side walls as well as in their collapsed position can be safely stacked on top of each other by means of catch corners.

To solve this complex problem, according to the invention primarily proposed that the bottom body is a (known per se) flat pallet, which is below her Platform has upwardly open guide profiles and that the side walls of the frame at the lower end of their spars pivotable around joint pieces and in the upright position can be locked with stub posts, which can be inserted and locked in the guide profiles,

In the case of use as a flat pallet, only the stub posts together with the side walls of the frame are required can be released from the guide profiles of the flat pallet.

When used as a lattice box pallet or as a collapsible container however, the side walls of the frame are locked in the stump post in the erect position on the floor body held while they unlocked for the transport of empties opposite the stub post and then against the Floor bodies can be folded down.

According to a further development feature of the invention, the bars of the side walls grip with their joint pieces for this purpose Slidable in the vertical direction in the stub post and are in the lowered position by special centering plug-in pieces in the stub post against pivoting

locked. Furthermore, it is provided according to the invention that the stub post over the platform of the flat pallet Reach at least the height of the side wall stack and are provided with catch corners at their upper end. It has been found to be particularly useful if, according to the invention, the length of the displacement path of the side wall spars in the stub post corresponds at least to the height of the side wall stack, because this results in the side walls can be folded down against the floor body in any order.

To ensure a secure hold of the tubular and / or wire mesh frame To ensure existing side walls on the flat pallet, it is provided according to a further development feature of the invention that the guide profiles of the flat pallet on the one hand and the stub posts on the other hand from matching interlocking square tubes ο. like. exist.

It can be particularly expedient to achieve a simple but stable design of the pallets according to the invention be when the joint pieces of the side wall spars are formed by cylinder bodies, the diameter and length correspond to the inner cross-section of the stub post and the are firmly connected to the lower end of the side wall spars, the side wall spars in an area between the cylinder body and the centering plug-in pieces have a smaller cross-sectional thickness than the stub posts and the stub posts on one side wall have a slot through which the spars with their offset Areas can be swiveled out.

So that the side walls cannot be unintentionally folded up when used as a lattice box pallet, another feature of the invention provides that the side wall spars and the stub posts can be non-displaceably coupled to one another via insertable locking members, for example screws.

Accidental lifting of the pipe and / or Wire mesh frame from the guide profiles of the flat pallet can be counteracted in a simple manner that the stub posts in the guide profiles of the flat pallet via releasable socket pin locks are lockable. In this case, it is also advantageous if the stub posts are located on the upper one by means of stops Can support the end of the guide profiles.

According to the invention, a particularly appropriate and structurally simple development also results from the fact that that the two transverse walls of the tubular and / or wire mesh frame are connected to the stub posts via their spars, while its longitudinal walls grip around the spars of the transverse walls by means of claws and on them by means of socket pin locks are definable.

Finally, an advantageous design feature according to the invention is also seen in the fact that the centering plug-in pieces the side wall spars are provided with downwardly tapering wedge surfaces through which a Play-free and flap-free locking of the side walls in their upright position on the stub post results.

The subject matter of the invention should be based on the drawing will now be explained in detail, namely shows

In Fig. 1 of the drawing is one of a plurality of the invention Pallet-formed pallet stack 1 is shown, which is formed, for example, from four individual pallets 2, 3, 4-, .5.

In this pallet stack 1, the two upper pallets 2 and 3 are flat pallets, the lower pallet 5 is a lattice box pallet with folded side walls, and the middle pallet 4 is as a lattice box pallet with erected Side walls inserted into the pallet stack 1.

From Fig. 2 of the drawing it can be seen that each of the flat pallets 2 and 3 has two parallel runners 10, which at their ends via upwardly directed guide profiles 11 and between these via an additional support 12 with a Angle frame 13 are rigidly connected. In the angle frame 13 a plate-shaped bottom body is inserted and connected to this, for example, by screws or rivets. The floor body is provided with square cutouts I5, that in this area the guide profiles 11 are open at the top.

• and assigned to two longitudinal walls 18 directed at right angles thereto, which are connected to one another to form a tubular and / or wire mesh frame protruding from the base body 14 can.

A complete side wall 17 of this tubular and / or wire mesh frame is shown in Fig. 2 of the drawing. In Fig. 5 of the drawing is a partial section of this side wall 17 and also a portion of one that can be connected to this Longitudinal wall 18 indicated.

From Fig. 2 it is clear that each side wall 17 has two has upright bars 19, the top by an angle rail 20 with two catch corners 21 and two centering pins connected, while at the bottom via an angled rail 23 are kept at a distance. Between the spars 19 and the Winke Is chi en en 20, 23 is a wire mesh 2A- as a closure element clamped. It goes without saying that when used as a folding container, profiled metal sheets as full-walled closure elements can be used both in the side walls and in the longitudinal walls.

With the lower ends of the two spars 19 is one down each directed arm 25 connected, which protrudes with the free end in an upwardly open stub post 26. Each stub post 26 is formed by a square tube and is at its upper end with a catch corner 27 provided. In addition, each stub post 26 is in one of its pipe walls with an upwardly open longitudinal slot 28, the width of which is slightly greater than the thickness of the arms 25.

At the free end of each arm 25, a cylinder body 29 is rigidly attached, whose diameter on the one hand and which Length on the other hand on the inner cross-section of the stub post 26 is coordinated in such a way that this cylinder body 29 fits into the stub post 26 with little lateral play engages and the sliding guide for the arm 25

forms. In the area of the longitudinal slot 28 of the stub post 26 also serves the cylinder body 29 as a joint piece, with the help of which the arms 25 through the Longitudinal slot 28 can be pivoted out.

Immediately below the spars 19 sits on the arms still a centering plug-in piece 30, which together with move the arms 25 relative to the stub post 26 leaves and engages appropriately in the upper ends of the stub post 26 in the lowered position. These centering pieces 30 form in the lowered position of the arms 25 coupling elements which the bars 19 in the Fix the stub post 26 against pivoting. Only when the centering plug-in pieces 30 come out of the stub post 26 are lifted out and the cylinder bodies 29 of the arms 25 lie at the level of the longitudinal slot 28 in the stub post 26, the side wall 17 can be opposite the two Fold over the stub post 26 from the erect position shown in FIG. 2.

The stub posts 26 are introduced from above into the guide profiles 11 of the flat pallet 16 and on their upper end supported by stops 31, so that the stub posts 26 with their catch corners 27 a certain distance of the bottom body 14 of the flat pallet 15.

This distance is dimensioned so that both the two side walls 17 and the two longitudinal walls 18 (Fig. 5) of the pipe and / or wire mesh frame flat on let the bottom body 14 of the flat pallet 16 lay, while the catch corners 27 of the stub post 26 still over lying on the side wall stack.

In Figure 3 of the drawings, a stub post 26 is an arm 25, a spar 19 and a centering plug 30 are shown with all essential details on a larger scale. 4, however, also shows on a larger scale

that with the angle frame 13 and a runner 10 of the flat pallet 16 connected guide profile 11, into which the stub post 26 can be inserted from above.

So that the arms attached to the lower end of the spars 19

25 not pulled completely out of the stub post upwards can be, a threaded piece 32 is attached to a side wall of the stub post 26, in which a Screw 33 can be screwed in. This screw 33 engages over the cylinder body attached to the lower end of the arm 25 29 and thus prevents the arm 25 from being able to be completely pulled out of the stub post 26. The one with the Arm 25 and centering plug-in pieces 30 connected to the spar 19 have downwardly tapering partial surfaces 34- »the on the one hand, allow easy insertion of the centering plug-in pieces into the upper ends of the stub posts 26 and on the other hand a play-free fixation of the spars 19 with respect to the stub posts 26.

Below their stops 31 have the stub posts

26 in at least one side wall an opening 35 » which after the insertion of the stub post 26 into the guide profiles 11 has a similar opening 36 in the guide profiles 11 is opposite. A slidably and rotatably mounted in a bearing tab 37 of the runners 10 Securing bolt 38 can be inserted into these openings 35 and 36 and locked by turning so that that the stub posts 26 are coupled to the guide profiles 11 so that they cannot move. So long as the socket pins 38 with the openings 35 and. 36 are engaged A secure connection between the side walls I7 and the flat pallet 16 is established via the stub posts 26.

From Fig. 2 of the drawing it can also be seen that both spars of the side walls 17 are provided with holes 39. The longitudinal walls 18 can be connected to the side walls 17 via these holes 39. The longitudinal walls 18 have, like

From Fig. 5 it can be seen, claws 40, which the spars 19 of the Reach around the side walls in the area of the holes 39 from the outside. A socket pin 41 can be pushed longitudinally on these claws 40 out so that it can be inserted into the holes 39 and thereby the cohesion of the longitudinal walls 18 with the side walls 17 guaranteed.

The measures described above result in a pallet version created that can be used equally well as a normal flat pallet as well as a lattice box pallet is. In the case of use as a lattice box pallet, while the side walls 17 and the longitudinal walls 18 for the Leerguttränsρort flat on the base body 14 to rest be brought without having to be released from the flat pallet 16. Since in this case the catch corners of the If stub posts 26 remain above the longitudinal and side wall stack, there is a perfect and safe stackability of the collapsed lattice box pallets. Also a mixed stack of flat pallets, collapsed Mesh box pallets and mesh box pallets with erected tubular and / or wire mesh frames easily possible, as can be seen from Fig. 1,

Thus, can be effective in a lattice box pallet with upright side walls 17 and longitudinal walls 18 a perfect stack fixation, grip the spigot 22 to the angle rail 20 of the side walls 17 i ⁿ centering holes 42 of the runners 10, as shown in Fig. 4 is a.
