Abstract

The transport pallets are designed for use with oblong objects, such a tubes, and are made in different sizes. The larger size pallets are made as multiples of the smallest pallet so that they can be stacked in any order. Each pallet has at least two cross rails. These rails are used for the location of parallel longitudinal frames. The pallet frame is completed by four tubular corners which provide vertical legs. Location brackets are provided at the bottom end of each leg to ensure secure stacking of the pallets.

Description

Stackable pallets

The invention relates to stackable pallets of different types Length for transporting and storing comparatively light objects such as thin-walled pipes and gutters.

The transport of goods of all kinds on pallets is already in place widespread and has proven itself. However, the disadvantage of known pallets is that that these are only available in constant, partly standardized dimensions and that therefore goods of different lengths cannot be transported using pallets can.

It is also disadvantageous that, as a rule, it is used for transport and storage the palletized packages of goods are stacked on top of one another, i.e. the lower goods have to take the load of the packages lying on it.

This means that easily damaged goods such. B.

thin-walled pipes that cannot be transported using pallets.

Another disadvantage of the known pallets is that they are not are suitable for real storage of goods, d. H. so when storing different Goods from lower, palletized packages cannot be removed.

It is the object of the invention to provide a pallet system or

to create a number of pallets of different lengths, which or which no longer has or have the aforementioned disadvantages and it should be possible for the first time with the solution according to the invention, easily damaged Goods of different, d. H. varying lengths with the same pallet system not only safe and easy to transport, but also after being stacked ion For this purpose, an easy removal of the goods from the lower ones is possible To enable pallets.

In particular, it is the object of the invention to create pallets in where pallets of different lengths can be stacked on top of one another, these being common or should be manageable individually and also together or individually as storage racks should serve. The pallets according to the invention should be particularly suitable for Transport for easily damaged goods, such as thin-walled pipes, elbows or Suitable gutters.

According to the invention, this object is achieved in that at least two cross members, longitudinal members and vertical struts are attached to them, below the struts on the underside of the side members Frame attached whose central opening has a cross-section that is slightly larger, than the cross-section of the struts and that the length of the larger pallets is an even number is a multiple of the length of the smallest pallet, that for all pallets in each case a pair of struts is arranged at the ends of the longitudinal beams that the center distance A of the struts adjacent to the outer struts in the longitudinal direction is equal to the center-to-center distance the frame of the smallest pallet that is adjacent in the longitudinal direction of the outer frame is and inside the next of the further struts and frames a center distance have, which is equal to the center-to-center distance B of the outer struts and frame on the head side pallets placed side by side.

Advantageously, especially with longer pallets, run close to the upper end of the struts between these tie rods. By the stack height above each To increase the pallet floor, additional, in the upper openings of the struts retractable struts or on their ends that are higher than the tie rods Slidable struts are available.

The struts can be advantageous for attaching wall or side elements made of rectangular hollow chamber profiles exist and wise in theirs Walls at least two one above the other and the hanging of wall parts between two adjacent struts permitting openings with the elongated holes an extension are at their upper end.

To increase the stability of the pallets and to facilitate the Handling of the same by means of forklifts can with larger spans of the longitudinal carrier further hollow chamber cross members are arranged on the underside of the side members be whose ends are open and whose width is greater than the width of the fork prongs of forklifts and their center-to-center distance is the center-to-center distance of the forks of forklifts is equivalent to.

To make it easier to place the pallets on top of one another, the The frames on the undersides of the pallets can still be open on one or both sides and to increase the stability of long pallets that have to be lifted in the middle are on diagonal anchors are attached to the outer ends between the struts.

In the following an embodiment of the invention is based on Drawings described in more detail. Show it: Figure 1 in perspective a number of stacked pallets of different lengths, Figure 2 a plan view of a longer pallet, Figure 3 shows the side view of the pallet Figure 2, Figure 4 the upper end of a strut and an inserted additional strut in section and FIG. 5 the view of a strut with the openings for hanging of wall parts.

The pallet system according to the invention has a number of pallets which have different lengths, e.g. B. 1, 2, 4 and 6 m. The length of the pallets is therefore an integral multiple of the length of the shortest pallet. The pallets themselves are designed so that they can be stacked on top of one another, According to FIG. 1, a number of smaller pallets can be placed on a longer pallet and a longer pallet can be placed on top of this if necessary.

The pallets consist of at least two cross members 1, on which longitudinal members 2 are attached. On the side members in turn, vertically extending struts 3 are attached, with each strut below 3 on the underside of the side members 2 frame 4 are present. These frames 4 are on one or both sides to make it easier to place the pallet to be placed on open and when one pallet is placed on top of the other, the upper end of each is opened a strut brought into engagement in the frame of the pallet to be placed. To make things easier this engagement is the cross section of each frame or that formed by the frame 4 opening slightly larger than the cross-section of each strut.

The struts are open at the top and to increase the support height for the Goods to be transported and stored can be placed in the upper openings of the struts 3 additional struts 7 can be inserted.

Adjacent struts by means of tie rods 10 are located near their upper end connected, which also represent hollow chamber profiles. Due to the special arrangement the struts are these with the exception of the strut pairs at the ends of the longitudinal beams also arranged in pairs in the longitudinal direction and within such a pair of struts tie rods are available in the form of steel strips. The tie rods 10 are otherwise Rectangular profiles. The Aufschiebeweg the additional struts 7 is through the stop on the tie rods 10 and 11 is limited.

In addition to the tie rods, the long ones must be lifted in the middle Pallets in the side parts still have diagonal anchors, which from the lower Part of the outermost strut to the upper part of the longitudinally adjacent Striving run.

To facilitate the lifting of the pallets and the support through to ensure the fork of a forklift truck is exactly centered and to increase the The longer pallets have stability through further hollow chamber cross members 8 on the underside the longitudinal beam 2, the ends of which are open and whose width is greater than that Width of the forks of a forklift truck and their center-to-center distance is the center-to-center distance corresponds to the forks of a forklift.

Another longitudinal member 9 is centrally located between these cross members 8 appropriate.

The struts 3 have at least on their longitudinal or transverse walls two openings 4 arranged one above the other, in which wall parts 6 are suspended can be.

The openings are advantageous as elongated holes with a extension designed at its upper end, so that bolts attached to the wall parts with thickened ends can be hooked and automatically by gravity lock. It is thus possible, especially for storage both at the transverse as well as the long sides of wall parts to hang as required, whereby the Transport of small parts that are shorter than the distance between the struts sure becomes possible. The wall parts can then be used to remove these small parts can be removed with a simple movement without the use of tools.

To stack pallets of different lengths on top of each other easily to enable, the arrangement of the struts 3 is now as follows: on the outside of each the pallet is above the cross member 1, which is also arranged on the outside are, a pair of struts is available. Another pair of struts is now sitting inside of the first-mentioned pair of struts with a center-to-center distance equal to the center-to-center distance of the corresponds to both strut pairs of the smallest pallet. Right next to the said one inner pair of struts another pair of struts is arranged so that also seen in the longitudinal direction a paired arrangement of the struts with the exception of the externally arranged struts results. Within this paired arrangement the center-to-center distance of the struts is the same as it is when there are two pallets are arranged butting against one another at the head, d. H. so it can be head-side against each other abutting pallets are placed on the struts. So the pallets show outer strut pairs on which stand alone and inner strut pairs, each are again arranged in pairs, so that the abutting edges of pallets shorter length can be safely supported.

Since there is also the corresponding mounting frame under each strut 4, the long pallets can of course also be safely stacked on top of one another will.

Since both the long and the short sides of the pallets are either remain open or can be easily opened by unhooking the wall parts can and continue to use said universal combination of pallets for stacking on top of each other is possible, so both the transport and the storage and in particular with the storage the removal of goods is particularly easy, so can from a ideal solution to the problems at hand.

The pallets according to the invention have the advantage that they are particularly light and the goods are not the burden of over it have to pick up stacked pallet packages. This is particularly advantageous Combination that the pallets can also serve as storage racks, a conversion of the Goods from the transport pallets in storage racks is therefore not required.

The invention can also be described in such a way that for palletized Transport parts of storage racks are used that can be stacked. These Parts are then to be described as self-supporting in the center, whereby through the struts a desired division and delimitation of the storage areas is possible.

The advantage here is that after loading the shelf segments or Pallets to the point of removal for consumption of the individual goods, which are clearly arranged They are arranged in a form and can be easily removed; manual repositioning work is not required is.

To make handling even easier, the pallets can be attached to the Longitudinal members and / or cross members can be provided with rollers. The usability will In addition, it is increased if wall parts are not only attached to the external struts can also be used as partition walls, the pallet space so subdivide for the transport and storage of different types of objects.

The wall parts are then attached to the struts which are arranged in pairs hooked.
