Description

The invention relates to a transport arrangement according to the features in the preamble of patent claim 1.

From the DE 10 2005 020 465 A1 a transport arrangement for fence elements is known in which longitudinal beams and cross members form a horizontal, rectangularly configured support frame. Upwardly directed holder arrangements are provided for the plug-in receptacle of pipe ends of the standpipes of the fence elements. Between the longitudinal beams and the cross struts extends a pallet floor. The distance between the lower edges of the inserted fence elements in a portion of the fence elements and the pallet base corresponds to at least 1.2 times the length of the pipe end. As a result, holding feet can be transported below the entrained fence elements. So that the support feet are not sideways fall down, are provided on the long sides flat iron to form an edge.

It is known to transport scaffolding frame on transport and storage devices, as in the DE 197 08 871 A1 are described. The transport of the scaffolding frame is done standing, with lower support rails are formed comb-like for the scaffolding frame. Holding means may be arranged at different points at different heights or extend over a certain height. As a result, the holding means can at least partially form the side wall of the transport and storage device according to the invention at the same time.

The German utility model DE 20 2006 012 275 U1 discloses a transport pallet and a transport arrangement with a transport pallet for fence or barrier elements, in which longitudinal beams and cross members form a horizontal, rectangularly configured support frame and in which the support frame holder assemblies for plug-in receptacle of pipe ends of the uprights of Zaunoder shut-off elements are provided. Angle irons are used as longitudinal beams.

It is essential to the invention that the fence or shut-off elements are arranged higher in a central region of the transport pallet than at least one in one Edge area of the transport pallet placeable fence or shut-off element. Fence or barrier elements placed in the edge area of the transport pallet act as side walls, which effectively prevent a lateral dropping down of retaining feet of the fence or barrier elements transportable on the transport pallet. The distance between the upper edge of the longitudinal bars and the lower horizontal bar of the fence or shut-off elements is so small that no holding feet can be pushed through the space between a longitudinal spar and a fence or shut-off. This design of a height-offset transport pallet has proven very successful. In practice, the sliding down of the support feet, however, was prevented not only by the horizontal latch of the fence or barrier elements, but also by an upwardly projecting edge in the region of the longitudinal beams. This edge was realized by a welded web plate. Originally, the longitudinal spars were made of angle iron. However, this had the disadvantage that the pallet could not be taken in the longitudinal direction with a forklift fork, but only in the transverse direction. Therefore, the longitudinal spars were replaced by rectangular tubes, which were suitable for receiving a forklift fork. Due to the omission of the upwardly pointing leg of an angle iron, the welded-on web plates were required for rectangular tubes in the sequence.

The need for such an edge has resulted from the fact that the lower end of the pipe ends rests on the transport frame. Since in this case the lower edge of the fence or barrier elements in the height range of the second layer of support feet, the lower support feet had to be prevented by this edge from slipping down. This lateral edge has been a hindrance under certain handling conditions. Although the edge does not interfere with the transport pallet is placed at ground level and the support feet need only be raised. Partly, however, the transport pallet is on the back of a truck. In this case, the individual support feet at the worker's chest should be lifted slightly and pulled over the edge. This is much more difficult than lifting the stones from a lower transport pallet. Due to the relatively heavy holding feet there is at least a theoretical risk of injury.

On this basis, the invention is based on the object to further develop a transport arrangement according to the features in the preamble of claim 1 protection to improve the loading and unloading of the transport pallet with holding feet and thereby reduce the risk of injury.

This object is achieved in a transport arrangement according to the features of the protection claim 1.

Advantageous developments of the inventive concept are the subject of the dependent claims.

It is essential that the tube ends of an edge of the transport pallet arranged fence or shut-off elements engage in laterally arranged the longitudinal bars pockets. Due to the laterally arranged pockets, the tube ends of the standpipes no longer lie on the support frame and thus not at the level of the pallet base, but are located next to the support frame in the pockets. As a result, the edge arranged fence or barrier elements can be positioned lower than all other fence or barrier elements on the transport pallet, with the result that their lower edge not only fixes an upper layer of support feet on the transport pallet, but even the lower layer of support feet. This eliminates the hitherto required edge, e.g. a flat iron, without replacement.

As a result, the support feet can now very easily push on the flat pallet floor, even if the transport pallet is arranged elevated and, for example, on the back of a truck. Just as easily as the transport pallet can be loaded, unloading is also possible. Only the edge arranged fence or shut-off must be removed in order to have unhindered in height access to all layers of stacked support feet.

Through the laterally arranged pockets angle iron or upwardly projecting flat iron in the edge region of the transport pallet can be completely eliminated. So far, such edge components were on the entire length of the transport pallet required. The welding work was correspondingly extensive. In the solution according to the invention, it is only necessary to arrange two pockets each side of the longitudinal bars. The welds for fixing the pockets are overall much shorter than the welds for attachment of angle iron or flat iron.

In advantageous developments, the holder arrangements can be releasably or non-detachably connected to the support frame. Detachable holder arrangements can thus be removed during empty transport and during storage of the transport pallet in order to reduce the risk of accidents and to save on transport or storage capacity.

The holder assemblies are in particular pivotally mounted on the support frame. In this way, the holder assemblies can be folded advantageous when not in use, so that they can not be lost or stolen.

The holder assemblies are mounted so that below the fence members on the holder assemblies at least two layers of support feet are transportable one above the other on the support frame. If the transport pallet is loaded with e.g. 20 fence or shut-off elements can be loaded, there is a need for the storage of 21 support feet. Depending on the size and weight of the support feet, these are inevitably stacked on the pallet floor. For this it is necessary to provide a sufficiently high space below the fence or shut-off elements. This is advantageously achieved by the greater height of the holder arrangements.

The holder assemblies have stops on their sides, via which they are supported on the fence or shut-off elements which can be placed next to the holder arrangements. In other words, the holder assemblies are fixed by the fence or shut-off in the folded-up position. In practice, an edge-side fence or shut-off element is first inserted into the pockets. As a result, the holder assemblies are in an upright position in which they are fixed by the fence or shut-off element and can not fold back. Subsequently, further fence or shut-off on the Holder arrangements inserted. At the same time follows the loading of the transport pallet with holding feet. Finally, a last fence or shut-off element is placed in the side of the longitudinal bars arranged pockets on the other longitudinal side, whereby the slipping down of the support feet is reliably prevented from the pallet base. Of course, the pallet base must also have retaining devices in the area of the holder arrangements, in order to prevent the holding feet stored on the transport pallet from slipping off the front side of the transport pallet. These restraints are therefore complementary to the longitudinal side walls formed by the fencing elements plugged into the pockets. Advantageously, the retaining devices angle iron or flat iron, which are welded to the transverse bars.

In particular, the pallet base is not a closed surface, but rather open and quasi designed as a grate. It preferably consists of parallel to the transverse bars and thus perpendicular to the longitudinal bars extending transverse struts, which are arranged at a distance from each other, which reliably prevents falling in relation to the dimensions of the support feet. The distance between the individual transverse struts is dimensioned such that each support foot always rests on at least two transverse struts, preferably on three transverse struts. Overall, the support frame contains by the cross struts a ladder-like structure, the transverse bars or cross struts form the sprouts. The transverse struts or rungs are preferably formed by T or angle iron, which are aligned in particular flush with the longitudinal beams with respect to their upper edge, so that there is a flat pallet floor without height offset between the longitudinal beams and the cross struts. The aim is to allow the unhindered loading and unloading of the support feet, i. to avoid as far as possible the edges protruding upwards.

Optionally, a pivotally mounted on the longitudinal beams or a attachable center support is provided. The center support serves to support shorter shut-off elements that do not extend over the entire length of the transport pallet and whose ends are held only on a holder assembly. By the Central support these shut-off elements are held in a horizontal position. Conveniently, the central support is associated with at least one locking element, via which the middle support is held in an upright position.

Shut-off elements are usually much shorter than fence elements, so that even with an overall shorter range holding feet in more than two layers must be stacked. As a result, there may not be enough space for a center support available. It is therefore provided in an advantageous development to provide the holder assemblies drop down brackets that serve as additional footprint for pipe ends of shut-off. The fold-down brackets are folded down towards the center of the transport pallet, so that even shorter shut-off elements, which are plug-in at one end, can be supported with their other pipe ends on a footprint. Since the shut-off elements are mutually plugged in, such a console which can be folded down towards the center is required on each holder arrangement. Folding down the consoles is important because the retainer assemblies are pivoted for transport, i. also be folded down to the middle. Thus, the consoles are not a hindrance when folding down the holder assemblies, they can be folded up for transport, so that they are arranged in a sense aligned with the holder assembly and thus rest overall during transport flat on the pallet base.

In accordance with the invention, the pockets are provided with upwardly facing spacer elements, on which rests the lower edge of an inserted fence or shutoff element. It is considered advantageous in this context that the lower edge is located approximately in the middle third of a holding foot. Preferably, the distance of the lower edge of the top of the pallet base corresponds to half the height of a retaining foot. The spacer elements also have the function not to let the lower ends of the tubular elements project too far down over the pockets. Preferably, the transport pallet has a total of a relatively low overall height, which is why the pockets preferably have a height which is not greater than the height of the longitudinal beams and especially the height of the longitudinal beams corresponds. The pockets are preferably cut-to-length rectangular profile tubes, which are welded longitudinally to the longitudinal bars and are open at the top and bottom with respect to their insertion openings. The elongated shape allows a length compensation of fence or shut-off elements.

Another advantage of these laterally arranged pockets is that the fence or shut-off elements are now plugged with both tube ends and are not only attached to the holder assemblies on one side, so that they can not slide down from the transport pallet neither at one end nor at the other end. The insertion depth is greater than in the area of the holder assembly, which ultimately represents a security gain, as is ensured even with a distortion of the transport frame by excessive or improper loading that edge fence or shut-off not slip out of the pockets and because it is also ensured that the support feet remain on the transport pallet. If the transport frame twisted under improper use, the pipe ends in the pockets may even jam, so that jumping out is impossible.

FIG. 1 shows a transport arrangement with a transport pallet 1, on which a fence element 2 is plug-in stock. To the transport arrangement also includes holding feet 3, 4, which are stacked on a pallet base 5 of the transport pallet.

An essential part of the invention is the transport pallet 1. The transport pallet, as in the FIGS. 2 to 4 is shown, comprises a horizontal, rectangularly configured support frame with mutually parallel longitudinal beams 7, 7a, which are connected to each other via outer transverse beams 8, 8a and inner transverse beams 9, 9a. In addition, a plurality of transverse webs 10 extend parallel to the transverse beams 8, 8a and thus perpendicular to the longitudinal beams 7, 7a. The transverse struts 10, together with the rectangular cross-sectionally configured longitudinal beams 7, 7a and the outer crossbars 8, 8a from the pallet base 5, on which the support feet 3, 4 can be stored.

Another essential part of the transport pallet 1 is a holder assembly 11, which is pivotable about the axis A to the center of the support frame 6 out. Such holder assemblies 11 are located at each end of the transport pallet 1. In FIG. 2 the holder assemblies 11 are in an upright position, in which they are ready to plug-in of fence elements 2. For transport, the holder assemblies 11 are folded down, resulting in a lower overall height during transport.

Loaded or unloaded transport pallets 1 can be transported by means of a forklift fork. The forks are transversely inserted into the inner transverse beams 9, 9a and longitudinally in the longitudinal beams 7, 7a. Both the transverse bars 9, 9a and the longitudinal bars 7, 7a are configured rectangular. The transverse bars 9, 9a are located below the longitudinal bars 7, 7a. The transport pallet 1 stands on the transverse bars 9, 9a. In addition, 1 support feet 12 are arranged in the corner region of the transport pallet, via which the transport pallet. 1 also gets up on the floor. The transverse beams 8, 8a and the support legs 12 provide a ground clearance of the transport pallet, which allows transport with hand lifting devices. The ground clearance is 10 cm.

It is essential in the transport pallet 1 according to the invention that laterally the longitudinal bars 7, 7a pockets 13 are arranged, in which each edge of a fence or shut-off element 2 can be inserted. The fence or shut-off elements 2 have at their ends in each case vertically extending standpipes 14, which are stuck in the construction of a fence or a barrier in holding feet 3, 4. Therefore, pipe ends 15 project beyond the lower edge 16 extending between the standpipes 14. The lower edge 16 of the fence element is therefore always lower than the upper edge of the associated holding foot. 3

As based on the FIG. 1 it can be seen, the lower edge 16 is in terms of their height approximately in the middle of the lower support foot 3, so that it can not slide down from the transport pallet 1 on the long side. Further, not shown fence elements may be plugged into the holder assemblies 11. For this purpose, the holder assemblies 11 are mounted at a height that a corresponding number of holding feet 3, 4 can be carried, which corresponds to the number of fence elements 2. Strictly speaking, a holding foot 3, 4 must be carried more than fence elements 2 are arranged on the transport pallet 1.

In FIG. 1 is a dash-dotted line located, which is intended to illustrate the lower edge 17 of those fence elements that are plugged into the holder assemblies 11. It can be seen that in this embodiment two layers of support feet 3, 4 can be transported one above the other, wherein the upper layer of support feet 4 fits comfortably under the center of the transport pallet 1 arranged fence elements 2.

Based on FIG. 4 It is clear that the corners 13 and arranged on the longitudinal side of the longitudinal bars 7 pockets 13 are each provided with upwardly facing spacer elements 18. The spacer elements 18 are arranged on the mutually facing sides of the pockets 13, so that the lower edge 16 of the in the pockets 13th inserted fence element 2 can be supported on the upper edge of the spacer elements 18. This prevents that the lower edge 16 rests on the upper edge of the pockets 13. Since the pockets 13 do not protrude above the level of the pallet base 5 upwards, the fence elements 2 would slide too deep into the pockets 13 without the spacer elements, so that their pipe ends 15 protrude too far from the pockets 13 which are open at the bottom. It is therefore considered expedient if the lower edge 16 is located approximately in the middle height range of the lower layers of holding feet 3. The spacers 18 therefore have a length which is between 40 and 60% of the height of the holding feet 3 to be carried.

The pockets 13 are rectangular in cross-section configured hollow profiles that allow a limited displacement of the inserted fence element 2 in the longitudinal direction.

Based on FIG. 3 It can be seen that the inner transverse beams 9, 9a on the outside project so far beyond the longitudinal struts 7, 7a that they form an alignment with the pockets 13. This ensures that the fence or shut-off elements retained in the pockets 13 are not damaged by the fact that a stacking fork is inserted deeply into the cross-members. The length of the inner transverse bars 9, 9a thus determines the width of the transport pallet 1. The outer transverse bars 8, 8a extend over the outer longitudinal sides of the longitudinal bars 7, 7a to the pockets 13. The outer transverse bars 8, 8a are in contrast to the inner cross members 9, 9a and the longitudinal beams 7, 7a not designed as hollow profiles, since only in the inner transverse beams 9, 9a and the longitudinal beams 7, 7a should be inserted a forklift fork. For this purpose, the longitudinal beams 7, 7a and the inner transverse bars 9, 9a are designed as rectangular tubes, which are stiffened against each other.

However, the fence elements 2 serve at the same time for fixing the holder assemblies 11 in an upright position. This is most vividly illustrated by the FIGS. 5 to 7 be explained. The illustrated holder assembly 11 comprises a horizontally extending traverse 19 of an angle iron. On the top of the cross member 19 pipe sections 20 are arranged at uniform intervals for plug-in receptacle of the pipe ends 15 of the fence or shut-off elements 2. Below the horizontal cross member 19 are two vertically extending Supports 21 arranged, which also consist of angle iron. A parallel to the longitudinal beams 7, 7a oriented leg of the supports 21 is provided at its lower end with a bore through which a bolt can be guided to the supports 21 and thus the holder assembly 11 pivotally connected to the support frame 6. For this purpose, there is a holder 22 on the support frame 11, which can be connected to the supports 21. The lower ends of the supports 21 are rounded off to one side, so that the holder elements 11 can only be folded inwards, ie towards the center of the transport pallet 1. The holder assemblies 11 can be secured in its upright position by the end of the cross member 19 abut protruding stops 23 on the stanchions 14 of the content in the pockets 13 held fence or shut-off elements.

The fence elements 2 are mutually attached to the holder assemblies 11, so that in each case a pipe end 15 of a fence element 2 with a pipe section 20 is engaged, while the other pipe end 15 is on top of the crossbar 19. As a result, length tolerances between the individual fence elements can be better compensated than with two-sided plug-in holders. In order to prevent the fence element 2, which is arranged on the outside on the holder arrangement 11 from slipping, a closure piece 24 in the form of an upwardly directed metal sheet is arranged on one end of the crossbar 19.

The FIGS. 8 and 9 show holder assemblies 11, which are each supplemented by a console 25. In FIG. 8 the console 25 is seen in its folded up position. In FIG. 9 the console 25 can be seen in its folded down position. The brackets 25 serve as it were to increase the footprint for the pipe ends 15 in the region of the traverse 19. The console 25 is in the folded-down position according to FIG. 9 at the same height as the footprint of the traverse 19 so that it is increased in size, so to speak. Based on FIG. 8 It can be seen that the console 25 in the folded-up position does not project beyond the longitudinal side of the traverse 19, so that the pivotable holder assembly 11 can be pivoted with the console 25 flat on the pallet base 5.
