Description

Transport pallet

The invention relates to a transport pallet for the standing transport of fence elements with the features in the preamble of claim 1.

Mobile fences not only have the function of delimiting an area with regard to accessibility, they also partially serve as a privacy screen. For this purpose, a covering is attached to a mobile fence. The wind load of a covered mobile fence is much higher. Holding feet made of heavy materials alone cannot absorb high wind loads from covered mobile fences. Additional side supports are required. If at the same time fence elements, holding feet and also support struts and corresponding fastening materials are to be transported on a transport pallet, the space on the transport pallet becomes very narrow. There are therefore proposals to transport pegs and other connecting elements in a rear wall, which is above the Bottom of the transport pallet. However, it is no longer a transport pallet, but a transport container. These upward-facing container areas are annoying when the transport pallets are empty because the stack height increases. But they also interfere with the unloading of the container. In addition, any container structures not only increase the construction volume, but also the empty weight of the transport pallet, which reduces the payload and in particular also increases the manufacturing and material costs for such a transport pallet.

It is state of the art that transport pallets have longitudinal beams which are arranged at a horizontal distance from one another. The transport area for the fence elements and the holding feet is located above the side members. Depending on the number of fence elements and the design of the holding feet, the holding feet must be transported in several layers one above the other. If the overall transport pallet is not to be widened, it is not possible to additionally transport support struts below the fence elements in the case of large holding feet, since the holding feet take up a lot of space. Small material can also be carried in a lower transport area below the bottom of the fence elements. For this purpose, it is known to arrange a transport trough in the middle area. This transport trough, which is closed at the bottom, is used to transport the so-called locks, via which the fence elements are connected. However, it is not possible to carry long struts in addition. One reason for this is that the support struts often have relatively bulky base plates which are arranged at a fixed angle to the support struts. With these foot plates, even greater transport space is required.

The invention has for its object to show a transport pallet for the standing transport of fence elements, which is improved with regard to the transport option for accessories, especially for long support struts, without the volume of the transport pallet increasing in the vertical or transverse direction. In particular, the transport pallet in the empty, unloaded state should not take up more space than a transport pallet of a conventional type. In addition, the aim is to be able to manufacture a corresponding transport range at low cost, while keeping the additional material expenditure low. A suitable transport arrangement for the transport of support struts for fence elements is also to be shown.

The transport pallet according to the invention with the features of claim 1 solves this problem. Just like a transport arrangement with such a transport pallet in which corresponding support struts for the fence elements are carried.

The transport pallet according to the invention for the standing transport of fence elements has two longitudinal beams. The two side members determine the length of the transport pallet. The two longitudinal beams are arranged at a horizontal distance from one another. The side members each have a top and a bottom. The two top and bottom sides are in a common horizontal plane. A floor should extend from side member to side member. The floor can be on the top of the side members. The side members can also be part of the upper floor, so that the upper floor extends between the side members. The tops of the side members also form part of the upper floor.

The term "floor" does not mean that the floor must be completely closed. There are preferably at least water drainage openings. Depending on the size of the holding feet to be carried for the fence elements, it may be sufficient to arrange struts between the side members on which the holding feet lie at predetermined intervals. The floor can be a lattice, a sheet metal or, in the broadest sense, an arrangement through which the components to be carried cannot fall if properly placed.

The term "holding foot" refers to holding feet made from heavy materials such as concrete, from recycled materials or from plastic, rubber, or from hybrid materials, and also holding feet made from metallic materials. The holding feet are used to set up the fence elements. They are not the fence elements themselves. The support feet can be transported overlapping or stacked on the top floor. The fence elements are arranged at a height that the holding feet can be carried under the fence elements. A sufficiently large free space remains between the fence elements and the upper edges of the holding feet to be carried, so that the holding feet can be easily gripped.

The invention includes that holding feet can also be accommodated in an area between the side members, specifically in the area of the upper half of the side members. For this purpose, the upper floor between the side members can be set slightly lower.

At least one holder arrangement is provided, which is attached to at least one end region of the side members. Holder arrangements are preferably located at both ends of the side members. The holder arrangements serve to receive downwardly projecting pipe ends of the fence elements which can be transported in the longitudinal direction of the supporting frame. The standing transport of the fence elements enables very space-saving transport and also good all-round accessibility.

The fence elements are especially plug-in. For this purpose, matching receptacles are provided on the holder arrangements for the pipe ends. The tube ends can, for example, be plugged onto pins or sleeves or can be accommodated in pockets or sleeves. The shape of the pockets can compensate for tolerance. The insertion opening is elongated and points in the longitudinal direction of the side members.

One tube end of each fence element is preferably plug-in, while the other tube end rests on a support surface which enables tolerance compensation in the longitudinal direction of the transport pallet. The one-sided plug holder also enables the mutual plug-in holder of successive fence elements. The non-plug-in tube ends are then position-oriented between the adjacent fence elements with play, specifically on the end at which the adjacent fence elements are both plug-in. A high packing density can be achieved because the horizontal and vertical tubes of the fence elements usually have different diameters. The vertical stanchions have a larger diameter than that horizontal pipes that extend in the lower and upper area between the standpipes. The non-plug-in pipe end is preferably in the transport position between the lower and upper pipes and is thus almost pinched. A transverse shift towards the side members is hardly possible. Such a package of fence elements is overall very safe for transportation.

The area in which the fence elements are located can be referred to as the upper transport area and the area below the fence elements in which the holding feet are located as a middle transport area that begins above the upper floor. Small parts such as clamps can be carried in a lower transport area. For this purpose, a transport container in the form of an upwardly open trough is used. This trough-shaped transport container preferably does not protrude above the upper floor and serves to receive connecting means, in particular clamps, in order to connect the fence elements to one another. If there is sufficient space between the holding feet, the transport container can be arranged in the middle transport area.

It is provided in the invention that the lower transport area is functionally considerably expanded. It not only extends below the upper floor in the sense that it is only lower, but it is also directly below the upper floor. Immediately below the upper floor means that the upper floor is located directly above said transport area, that is to say vertically above this section of the lower transport area. The transport containers can and should be loaded from above. They are therefore not vertically below an upper floor, but next to it in the horizontal direction. For quick dismantling, small parts can be thrown into the transport container until the transport container is full. The horizontal section according to the invention of the lower transport area is not intended for this accessibility from above.

Said section of the lower transport area is only accessible from the front of the transport pallet. Rod-shaped material can be pushed over the end faces like in a drawer or in a compartment under the upper floor will. The section of the lower transport area according to the invention is bounded at the top and bottom by the floors.

The invention is therefore characterized in that a further section of the lower transport area of the transport pallet is used for the transport. This section was previously completely unused. In particular, support struts that are transported below the upper floor can be carried in a space-saving manner so that the transport pallet does not have to be converted into a transport container in which there are further superstructures above the upper floor. When empty, these would significantly increase the volume of the transport pallet. They lead to additional manufacturing costs. The material costs would also be higher. The invention avoids these disadvantages.

Rod-shaped, i.e. long, slim accessories such as support struts are thus pushed from the front of the transport pallet between the side members to be stored on the lower floor. This lower floor extends in particular between the side members. The term "stretch" can mean that the bottom floor is a connection between the left and right side members. The term "lower floor" also encompasses a floor that does not extend completely from longitudinal member to longitudinal member, but is at least partially a suspended floor that is supported by the upper floor. There may be a connection between the upper and lower floor. The lower floor can, for example, consist of a plurality of bow-like holders which are open at the top and are arranged below the upper floor. The decisive factor is the function of the lower base for receiving rod-shaped materials or the underside support for rod-shaped materials. Bar-shaped, rigid materials do not require a large number of supports. There must be at least two supports, one for each end of the bar material.

The invention is also characterized in that a securing against longitudinal displacements is provided in the area of the lower transport area. Securing against longitudinal displacements serves to secure those carried along there Load, especially for securing bar materials, preferably support struts for the fence elements.

The support struts have a relatively low weight and, unlike the fence elements or holding feet, are not held in a particularly secure position by their own weight. In particular, if the lower floor has only a very small number of support points for the bar material, the friction of the bar material with the lower floor is also low. Therefore, an additional safeguard against charge shifting is provided. This is in particular a mechanical barrier that prevents the load from sliding down from the lower floor. Securing against cargo shifting does not have the function of holding the cargo exactly in the same place, but rather to prevent the cargo from being lost due to transport and, moreover, can only be removed from the lower transport area through targeted handling during unloading.

For this purpose, a preferred development of the invention provides that cross struts are arranged at the end regions of the longitudinal beams, which struts are open at the top, the lower floor being partially formed by the cross struts. The cross struts open at the top can e.g. B. U-iron. These cross struts act as a safeguard against load shifting in active engagement with the load to be carried in the lower transport area. If the load is a support strut, its ends can end, in particular, in the area of the cross struts which is open at the top, so that the support struts or their base plates engage in a form-fitting manner with the cross struts.

In particular, the cross struts open at the top are U-shaped or V-shaped in cross section with two legs oriented upward. At least one of the legs has the function of securing against load shifting. In particular, the legs are of different heights. At least one of the two legs is only so high that base plates of the support struts can be guided past the leg for horizontal insertion. The base plates usually have a center of gravity that is at a distance from the longitudinal axis of the support struts. As a result, a horizontal support strut, which is round in cross section, automatically rotates so that the The center of gravity of the base plate is at the lowest point. As a result, the base plate grips safely behind the legs of the cross strut even during transport. The legs serve as a safeguard against load shifting in the longitudinal direction of the transport pallet.

The cross struts perform the following two functions in particular: First, they connect the end regions of the side members. This stiffens the transport pallet. Secondly, they serve as supports in the area of the lower floor. In combination with the cross members in the middle area, a floor is created which is sufficient for the transport of bar material. The bar material only has to be placed on the cross beams in the middle area and on the cross struts in the end area. The ends of the support struts are held in the cross struts that are open at the top and cannot slide off the transport pallet on their own.

Legs of the cross struts of different heights can simplify loading and unloading. In particular, the outer of the two legs is shorter than the inner leg. The inner leg has a height that defines the height of the lower floor. The upper edge of the inner leg is therefore preferably in the area at the height of the top of the cross member in the central area of the transport pallet. As a result, the lower floor is in particular parallel to the upper floor.

In a development of the invention it is provided that a cross strut which is open at the top can also be formed by a cross profile arrangement comprising a plurality of cross profiles. A cross strut therefore does not have to be made in one piece. It can therefore have several functional areas that do not necessarily have to be connected to one another. For example, a lower part of the cross strut can serve as a support. Wall areas or legs of the cross struts do not have to be full-surface or closed. It is expedient if the upper edges of the cross profile arrangement which is open at the top are arranged at heights which enable loading of the lower floor and at the same time also form load securing means. Basically, it is therefore sufficient if there is an underside bottom in cross section and somewhat higher at a distance from the bottom arranged profiles that serve as a safeguard against load shifts. A round bar or a flat bar extending from side member to side member may already be sufficient for this.

In an advantageous further development, such a cross profile arrangement therefore has an upper cross profile and a lower cross profile, the said cross profiles being arranged at a distance from one another. Two upper cross profiles can also be combined with a single lower cross profile, so that the higher, upper cross profiles in combination with the lower cross profile provide an open cross profile arrangement that is comparable in cross-sectional contour to the functional areas of one after cross strut open at the top. Open to the top means that a space is limited that can be loaded from above, i.e. has a loading opening on the top.

In particular, an upper cross-section serves as part of the lower floor, while a lower cross-section is arranged at a distance from it and has a protection against load shifts. Such securing against load shifts can be achieved in that the lower cross section is essentially L-shaped and has a single leg pointing upwards. The upper transverse profile, on the other hand, can also fulfill the function of the floor if it is not oriented like a vertical leg, but essentially horizontally in the longitudinal direction of the floor, in particular in the form of a flat iron. This flat iron can be arranged at a greater distance from the parallel lower leg than an upper edge of the vertical leg of the L-shaped lower transverse profile. The upper cross section can be solid, for example a rod or a flat iron. The interaction of at least one lower and at least one upper cross section creates a cross section arrangement that is functionally equivalent to an upwardly open cross strut. For this reason, the term cross strut also includes a cross profile arrangement comprising a plurality of cross profiles.

The cross members in the middle area also serve to hold a fork. It is possible within the scope of the invention to empty or load the transport pallet both by engaging in the cross members and in the longitudinal members transport. For this purpose, the side members are at a distance at which a fork can be inserted. The cross section of the side members is adapted to the shape of the fork.

The cross members preferably have the same cross section as the longitudinal members. The transport pallet can thus be moved in the longitudinal direction. The fork is located in the side members. It can be moved in the transverse direction when the fork is in the cross member. The accessibility for loading and unloading the transport container is given on all sides.

The cross struts can also perform another function: in particular, the undersides of the cross struts and the cross beams determine a common underside of the transport pallet. The transport pallet rests on these undersides of the cross struts and cross beams. The position of the undersides of the end cross struts is important for the stacking of loaded transport pallets. Loaded transport pallets, d. H. those with fence elements on them can be stacked in two or more layers. To do this, there must be a corresponding support surface on the underside of an upper transport pallet. Because the cross member now defines an underside of the transport pallet and extends in particular from longitudinal member to longitudinal member, a very large bearing surface is created on which the upper transport pallet rests and by which it can be supported on the fence elements of a lower transport pallet.

The holder arrangements determine the height of the empty transport pallet. In its basic form, the transport pallet has the shape of a cuboid with an underside and an upper side running parallel to the underside, so that the transport pallets can be stacked parallel and straight above one another. Stacking is possible even if support struts are arranged in the lower transport area or holding feet are also arranged above the upper floor. The holder arrangements determine the height of the unloaded transport pallet. It is therefore possible to use the transport pallet to transport accessories such as support feet and support struts and to stack them one above the other to store. There are no other structures that are higher than the upward holder arrangements for plug-in of the fence elements.

In a further development of the invention, at least one upper transport container which is open at the top is provided on the transport pallet. It can be located at least partially above the upper floor, with an upper edge of the upper transport container not lying higher than an upper side of the holder arrangement. An upper side of the transport container is preferably not higher than the upper floor. The transport container is used for carrying small materials, in particular for transporting clamps for connecting adjacent fence elements. Ground anchors that are required to fix support struts to the ground can also be transported in the transport container. The transport container, which is open at the top, can be divided into several compartments or in several parts. It has side walls. The side walls are arranged so that they do not collide with one another when the transport pallet is stacked. In particular, they are beveled. The bottom of the transport container has water drainage openings.

The transport container can be arranged completely above the upper floor or end in the area of the upper floor. It can also be attached a little lowered so that it is partially between the side members.

In an alternative embodiment, it is possible for at least one lower transport container which is open at the top to be arranged in the lower transport region, the upper floor being interrupted in the region of the transport container. The lower transport container is then in the lower transport area without protruding over the upper edge of the side members. This deep, lower transport container is loaded from above and is also used to hold small parts such as clamps and ground anchors. The edges of the transport container are in particular at the level of the upper base, so that with correspondingly small transport containers, several of the adjacent edges form a resilient support edge in the area of the upper base. As a result, holding feet can also be transported above the transport container without falling into the transport container. However, the trough-shaped transport container itself is only loaded from above and not from the front of the transport pallet. The lower transport container preferably begins at the height of the lower floor. This divides the lower transport area into at least three horizontal sections. The transport container itself is located in a first section of the lower transport region. For reasons of weight distribution, the transport container is preferably located in the middle of the side members and thus in the middle of the transport pallet. Here the top floor is open. To the side of this transport container are two sections of the lower transport area immediately below the upper floor. Bar material can be carried here.

This middle transport container can extend in height up to between the cross members d. H. even to the bottom edge of the entire transport range. It is then very deep and definitely divides the lower transport area into three horizontal sections. However, since the transport container cannot lie lower than the underside of the transport pallet, it is not an obstacle when stacking empty transport pallets.

In a further embodiment, a bottom of the transport container is above and at a vertical distance from the lower bottom of the lower transport area. This creates a free space below the transport container that can be used. The lower transport area for bar material therefore extends below the transport container. In this way it is possible to provide on the transport pallet both a transport container in which small material can be accommodated and at the same time to transport very long support struts which are longer than half the transport pallet. The support struts can protrude from both sides to below the transport container. It can also carry struts that are not only longer than half the transport pallet, but as long as the transport pallet itself or even longer than the transport pallet, if this is expedient or necessary.

The transport container can be firmly, ie non-detachably, in particular welded to the transport pallet. In an advantageous embodiment of the invention, the at least one transport container is detachably connected to the transport pallet, especially screwed. The detachable connection to the transport pallet enables the customer and the manufacturer to use a modular system. The modular system comprises a uniform base frame that can be coupled with various transport containers.

The principle of a uniform base frame in combination with several transport containers can also be extended to the holder arrangements. With different holder arrangements, the transport range can be adapted to different fence elements or loading scenarios. For example, holder arrangements can be arranged at different distances or can also be provided with a different number of holders for plug-in holding of fence elements. The fence elements from different manufacturers have different standpipes. Different holders can therefore also be provided for the plug receptacle.

If necessary, the transport pallet can also be converted to transport shut-off elements or barriers. The term fence element in the context of the invention encompasses flat components with standpipes at the ends, these flat elements being to be transported in an upright position. The flat elements can consist of plastic, metal, or hybrid materials. The fence elements require additional components such as support feet or support struts to be erected, which are connected to the fence elements as required.

The holder arrangements are preferably pivotable from a vertical position into a space-saving, essentially horizontal position. For this purpose, they are folded inwards in opposite directions by about 90 ° onto the transport pallet. The pivoted holder arrangement is in particular no higher than the distance between the lower floor and the underside of the transport pallet. This makes it possible to stack the transport pallets on top of each other in an especially space-saving manner.

Basically, it is considered advantageous if the different height ranges of the transport pallet adhere to a grid dimension of approx. 80 - 100 mm. A grid dimension of approximately 80 mm is preferred. That means the lower ones Cross members have a height of approx. 80 mm so that normal pallet forks can be inserted into the cross members. Above the cross member are the side members, which also have a height of approx. 80 mm. This allows forklift forks to be inserted into the side members.

In this case, the lower transport area has a height that preferably corresponds to the height of the longitudinal bars. The lower transport area preferably has a height of approximately 80 mm.

The holder arrangements have a height above the upper floor, which is chosen so large that there is enough space below the fence elements for carrying the holding feet. The fence elements are also arranged in accordance with the height of the holder arrangements. Only in the empty state should the holder arrangement be able to be folded down so flat that it is no more than approx. 80 mm high. As a result, the holder assembly fits under the longitudinal bars when folded down.

A space for the cross struts at the ends of the side members remains between the pivoted holder arrangements. The cross struts should not cause the stack height to increase when stacked. They should therefore be somewhat narrower than the clear width between the side members. As a result, the cross struts can grip without jamming between the longitudinal spars of an identical lower transport pallet when stacking empty transport pallets.

While a lower transport pallet of a stack of several identical transport pallets has a height of 3 ^c 80 mm = 240 mm, the stack height only increases by 2 x 80 mm = 160 mm due to each additional transport pallet. With each additional layer of empty transport pallets, a stack height of 80 mm is saved. The close interlocking of the transport pallets prevents mutual shifting. A stack of empty transport pallets can therefore have a considerable height without endangering operational safety, even if a stack has to be moved. In addition, it is possible at any time to remove any number of transport pallets from the stack, since in any case the openings in the side members and cross members remain free. The transport pallet according to the invention is in particular part of a transport arrangement with the features of claim 21.

The transport arrangement according to the invention is characterized in that support struts for the fence elements are arranged in the lower transport region. The support struts for the fence elements are intended to be arranged at an angle to the fence elements, one end being anchored to the ground and the other end being connected to the fence element. The support struts are particularly fastened in the ground via ground anchors, for example in the form of pegs, in order to give the fence elements increased stability.

The support struts are preferably no longer than the side members d. H. maximum as long as the side members. This means that they do not protrude over the ends of the side members during transport. They are preferably located completely between the side members during transport. In this way, several loaded transport pallets or transport arrangements can stand close to one another without the risk of the load being damaged. For longer support struts with a length of e.g. The support struts can be telescoped over 3.50 m. Each individual telescopic shot is preferably no longer than the transport pallet.

The support struts preferably have base plates. Such floor panels are connected to the support struts at a predetermined angle. They therefore require additional transport space, which you can find in the cross struts that are open at the top. The base plates protrude downwards into the cross struts that are open at the top. The support struts themselves lie on an upper edge of an upstanding leg of the cross struts and then engage with the base plates behind the upper edge. The upper edge is preferably the higher edge. For loading and unloading, the front, ie outer leg of the cross struts is preferably shorter, so that the support struts can be easily pushed into the lower transport area and can also be pulled out again. As already described above, the base plates can preferably be pivoted through an angle of 90 ° for this purpose. In this case, loading and unloading of the lower transport area takes place exclusively via a loading and unloading opening in the end area of the transport pallet, ie via an opening below the holder arrangements and above the cross struts. The opening is laterally limited by the side members.

As with a drawer, the support struts are pulled out over the end faces or inserted into the transport area. The loading and unloading direction runs parallel to the longitudinal direction of the side members. For this reason it is also possible to completely close the floor above and below the lower transport area. Loading from above is not possible for long support struts and also not very practical. It is therefore more expedient for the support struts from the ends of the transport pallet below the actual loading area, ie. H. to slide under the top shelf and also to be removed by pulling it out at the end.

In the transport arrangement according to the invention, it is not only expedient to carry support struts for the fence elements, but also the necessary fastening means for the support struts. In the transport arrangement according to the invention, these are arranged in the transport container. The fastening means are, in particular, clamps for connecting the fence elements and supports as well as fastening means on the floor area, in particular earth anchors, in particular earth nails.

The transport pallet according to the invention is preferably made of galvanized steel. It preferably has a high variability due to a modular system, in which holder arrangements and transport containers can be connected to a base frame as required, the transport pallet overall being a flat, essentially cuboid component with a container area below the actual pallet base. The transport pallet makes ideal use of the space between structural elements of the frame without increasing the total weight of the transport pallet. The functionality is expanded considerably. The application range of the transport range is enlarged and improved. The invention is explained below with reference to exemplary embodiments shown in schematic drawings. Show it:

FIG. 1 shows a transport pallet 1 for the standing transport of

Fence elements. The fence elements are not shown. You will be in

Longitudinal direction of the transport pallet 1 and are transported with their vertical tube ends held in brackets, as will be explained below. FIG. 1 shows that the transport pallet 1 has longitudinal beams 2, 3 arranged at a horizontal distance from one another. The longitudinal beams 2, 3 are rectangular hollow profiles in cross section. They allow the insertion of a stacker fork at the end for transporting the loaded or unloaded transport pallet 1. In this exemplary embodiment, the height of the longitudinal beams is 2.3 80 mm. The longitudinal beams 2, 3 have an upper side 4. The upper sides 4 of the two longitudinal beams 2, 3 are located in a horizontal plane which determines the position of an upper floor 5. The upper floor 5 also extends between the two longitudinal beams 2, 3. Between the two longitudinal beams 2, 3 extending struts 6, which are arranged at a parallel distance from one another and at a 90 ° angle to the longitudinal beams 2, 3. The struts 6 are arranged at a distance from one another, which makes it possible to carry 5 holding feet for the fence elements on the upper floor. The holding feet can be stacked in one or more layers on top of each other on the floor 5 and so high that they fit under the fence elements.

The two side members 2, 3 are connected to one another via cross members 7, 8 in the central region of the side members 2, 3. The cross members 7, 8 are welded to the side members 2, 3. The longitudinal beams 2, 3 rest with their undersides 9 on the cross beams 7, 8. The longitudinal beams 7, 8 have the same cross section as the cross beams 7, 8, ie they are rectangular in cross section. They have a height of 80 mm. They are arranged at a distance from each other that enables a fork to be inserted. The cross members 7, 8 protrude slightly along the longitudinal members 2, 3 from the outer longitudinal sides of the longitudinal members 2, 3. This creates a stop for a stacker fork so that the stacker fork cannot travel to the long sides of the side members 2, 3 under the transport pallet 1. The reason for this is that pockets 10, 11 are arranged on the outer longitudinal sides of the longitudinal beams 2, 3, into which a fence element with its tube ends can be inserted from above. The pockets 10, 11 and a fence element inserted therein are to be protected against deformations. The pockets 10, 11 provided for insertion have elongated insertion openings which are oriented in the longitudinal direction of the transport pallet 1 are. This serves to compensate for tolerances with regard to the fence elements. In addition, the pockets 10, 11 are arranged at a depth such that a lower edge of the fence elements, which extends between the standpipes, serves as a barrier for the holding feet to be carried, so that they cannot fall off the transport pallet 1. Another function of the edge-side fence element is to hold pivotable holder arrangements 12, 13 in a vertical position. For this purpose, brackets 14, 15 are arranged on the holder arrangements 12, 13, which reach behind the standpipe of an inserted fence element on the edge. As a result, the holder assemblies 12, 13 are held in the vertical position until the last fence element has been removed.

When all fence elements have been removed, the holder assembly can be swung down. This is shown in FIG. 8.

The longitudinal beams 2, 3 and the cross beams 7, 8 form an essentially rectangularly configured, horizontal support frame which forms the basic structure of the transport pallet 1. Above this supporting frame there are only the two holder arrangements 12, 13 as the highest towering superstructures, which no other component projects above. The basic volume of the transport pallet is a flat cuboid. This enables the loaded and unloaded transport pallets 1 to be stacked one on top of the other.

The holder arrangements 12, 13 extend across the transverse direction of the transport pallet 1 in each case in the end region of the longitudinal beams 2, 3 and at a vertical distance from the upper sides 4 of the longitudinal beams 2, 3. The holder arrangements 12, 13 each comprise a plurality of tubular holders 16 which are used for the plug-in receptacle of matching pipe ends of fence elements. The holders 16 preferably engage in the tube ends of the fence elements. The holders 16 are fastened on cross members 17. The cross members 17 are in turn connected to the longitudinal beams 2, 3 by two arms 18, 19 which are attached to the cross members 17 below. For this purpose, the bearing plates 20, 21 are arranged on the mutually facing inner sides of the longitudinal beams 2, 3, the bearing plates 20, 21 also extending upward over the upper sides 4 of the longitudinal beams 2, 3. The arms 18, 19 can be pivoted on the longitudinal beams 2, 3 via aligned bores arranged there stored. The spacing of the holder arrangements 12, 13 from one another can be varied by adapting to fence elements of different lengths by means of a plurality of bores offset in the longitudinal direction of the longitudinal beams 2, 3.

The fence elements are inserted alternately, so that one tube end of a fence element is plug-in and is in engagement with one of the holders 16, while the other tube end of the same fence element lies freely on the other crossmember 17 of the other holder arrangement 13. The distances between the holders 16 are selected so that a high packing density of the fence elements is achieved and at the same time certain length tolerances at the free ends of the fence elements can be compensated for. The pipe ends of the fence elements which do not engage with a holder 16 on the edge cannot slide down from the cross member 17, since in any case an outer fence element is inserted into the pockets 10, 11 arranged along the longitudinal members 2, 3.

FIG. 1 also showed that transverse struts 22, 23 are arranged below the holder arrangements 12, 13 and also below the longitudinal beams 2, 3. The cross struts 22, 23 are located exactly below the holder arrangements 12, 13 in the vertical direction.

In the middle area of the transport pallet 1 there is a transport container 24. It extends between the two longitudinal beams 12, 13. It is trough-shaped and open at the top and serves to hold accessories for connecting the fence elements to be carried.

Figures 2 and 3 show sectional views of the transport pallet 1. The transport pallet 1 is shown in a section through its vertical central longitudinal plane. It can be seen from FIG. 3 that the struts 6 are angle irons, a horizontal leg being located at the top 4 of the longitudinal beam 3 and thus determining the height of the top floor 5. FIG. 3 also shows that an upper side 35 of the cross member 8 (preferably) lies at the same height as an upper edge 25 of a leg 26 of the upwardly open cross strut 22. The cross strut 22 has a further leg 27, which is shorter than the other Leg 26. The position of the upper edge 25 of the leg 26 and the top 35 the cross strut 8 delimits a height of a lower floor 28. This lower floor 28 runs parallel to the upper floor 5 and defines a section of a lower transport area 29, which is shown hatched. The lower transport area is the area that is located below the upper floor 5. The height of the lower transport area 29 is determined by the distance between the upper floor 5 and the lower floor 28. The length of the lower transport area 29 is determined by the length of the longitudinal beams 2, 3 and the width of the transport area 29 by the clear width between the two longitudinal beams 2, 3. The section of the lower transport area 29 used according to the invention is the section which is arranged directly, ie vertically below the upper floor 5 (hatching). In this sense, the lower transport area 5, viewed towards the center of the transport pallet 1, ends at the strut 6, which is adjacent to the transport container 24. The transport container 24 is open at the top in order to be able to insert small parts from above. In this embodiment, the transport container 24 is located partly between the longitudinal beams 2, 3 and partly above the longitudinal beams 2, 3. Therefore, a part is also below the level of the upper floor 5. This part of the lower transport area can only be loaded from above , because a bottom 30 of the transport container 24 is closed at the bottom.

FIG. 3 also shows that the height H1 of the transport pallet 1 is determined by the upright holder arrangements 13 and the holders 16 arranged thereon. From the side view it can also be seen that the bearing plate 21 has the bores mentioned above in order to be able to move the holder arrangements 13 in the longitudinal direction of the transport pallet 1. The holder arrangements 13 can also be exchanged for other types of holder arrangements 13. Likewise, the transport container 24 in the middle of the transport pallet 1 can be exchanged for other designs. For this purpose, it is detachably connected to the longitudinal beams 2, 3. FIG. 1 shows screw tabs 31 on the inner sides of the longitudinal beams 2, 3. The transport container 24 is screwed to the screw tabs 31 in a manner not shown in detail.

FIG. 4 shows how the section of the lower transport area 29 according to the invention can be used. From the perspective view The sectional view shows that a support strut 32 is arranged in the lower transport area 29. The support strut 32 has a base plate 33 which is firmly connected to the support strut 32 and is at an angle to the longitudinal direction of the support strut 32. The base plate 33 is arranged approximately at a 45 ° angle to the support strut 32. The base plate 33 projects downwards in the transport position. The dead weight of the base plate 33 always pulls the base plate 33 down, so that the base plate 33 cannot automatically slide out of the cross strut 22. In addition, the base plate 33 engages behind the outer legs 27 of the cross struts 22.

For insertion into the flat lower transport region 29, the support strut 32 can be pivoted 90 ° about its longitudinal axis, so that the flat base plate 33 is initially in a horizontal position in order to be pivoted downwards again by 90 ° after insertion. If the lower transport area 29 is high enough and the outer leg 27 is short enough, the game that is present in this way can also be used and the base plate 33 can be raised in the position shown above the lower leg 27 of the cross strut without rotating the support strut 32.

The illustration in FIG. 5 showed that the support struts 32 are pushed from both end faces in the longitudinal direction of the arrows P1, P2 under the upper floor 5 into the lower transport area 29. Even if the upper floor 5 ends in the area of the inner struts 6 adjacent to the transport container 24, it is possible within the scope of the invention to push the support struts 32 offset from one another from both end faces to below the transport container 24. The support strut 32 is inserted alternately into the lower transport area 28. They lie with their outer ends on the cross struts 22, 23 and with their inner areas on the cross members 7, 8. They are located parallel below the upper floor 5. Additional struts in the area of the lower floor 28 are not required. The lower floor 28 is formed by the upper sides 35 of the cross members 7, 8 and the end cross members 22, 23. This is sufficient to be able to carry a large number of support struts 32 in a very space-saving manner. The perspective view of FIG. 6 at the end region shows that the cross strut 22, which is open at the top, has a width B1 measured transversely to the longitudinal direction of the longitudinal beams 2, 3, which is indicated here, whereby the width B1 is smaller than the clear distance B2 between the Longitudinal beams 2, 3. Even if the cross struts B2 are somewhat narrower upwards, the loading volume for the support struts 32 is not reduced as a result.

FIG. 7 shows in a view from below that the support struts 32 can be carried along in part at a horizontal acute angle to the side members 2, 3. In no case can they slip out of the lower transport area 29, even if the usable width B1 of the cross struts 7, 8 is smaller than the distance B2 between the longitudinal beams 2, 3.

The reason for the smaller width B1 of the cross struts 22, 23 is that the transport pallets 1 are to be stacked in a particularly space-saving manner.

FIG. 8 shows two transport pallets 1 of the same type one above the other in a stacked arrangement. The end holder assemblies 12, 13 are each folded down. It can be seen clearly from the enlarged illustration in FIG. 9 how the cross strut 23 of the upper transport pallet 1 fits between the folded-down holder arrangement 12 and in particular is guided past the bearing plate 21 with play on the inside. As a result, the upper transport pallet 1 grips overall without jamming between components of the lower transport pallet 1. And in particular between the bearing plates 21 including the arranged screw bolts.

It can be clearly seen from the illustration in FIG. 10 that the folded-down holder arrangements 12 can be folded down so flat that the transport pallets 1 of the same type can be stacked lying on top of one another in parallel, the cross bars 7 resting on the longitudinal bars 8. Furthermore, it can be clearly seen that the cross strut 23 in the form of a box profile open at the top has a very large lower support surface, by means of which the transport pallet 1 can be supported as a whole, especially if an upper one Transport pallet 1 is to be placed on a lower transport pallet 1 loaded with fence elements.

Due to the fact that the cross members 7, 8 and the longitudinal members with 2, 3 each have a height of approximately 80 mm, the height of the folded-in holder arrangement 12 is likewise limited to approximately 80 mm. The upper transport pallet 1 therefore lies on the holder arrangement 12 (FIG. 10). Centering tabs 33 on the outer longitudinal sides of the longitudinal beams 2, 3 between the cross beams 7 and 8 prevent the stacked transport pallets 1 from slipping in the longitudinal direction and ensure that they are positioned exactly vertically one above the other. A transverse displacement is not possible because the cross struts 22, 23 grip between the bearing plates 20, 21.

The exemplary embodiment in FIG. 11 shows that it is entirely possible to insert a far larger number of support struts 32 into the lower transport region 29 from one side. If the support strut 32 is short, so that there is no overlap in the central region of the transport pallet 1, the number of support struts 32 to be carried can even be doubled.

FIG. 11 shows that partially loaded transport pallets 1, in which the support struts 32 are arranged in the region of the lower transport regions 28, can also be stacked one above the other without the stacking height increasing due to the support struts 32.

FIG. 12 shows a further exemplary embodiment in the same representation as FIG. 4. The difference from FIG. 4 is that the support strut 32 there is designed as a transverse profile arrangement 36 or 39. Such a cross profile arrangement 36, 39 each consists of several cross profiles. Each cross profile arrangement 36, 39 has a lower cross profile 37, 40 in the form of an upwardly open cross-section L-shaped profile. The lower leg of the L-shaped profile forms the underside of the respective transverse profile arrangement 36, 39 analogously to the bottom of the support strut 32 (FIG. 4). The vertical leg provides protection against load shifts. The vertical leg is on the outside. The difference from the exemplary embodiment in FIG. 4 is that the inner vertical leg is not connected to the lower transverse profile 37 or 40. Rather is a Upper cross section 38, 41 is provided, which is part of the lower floor and on which the support strut 32 shown rests. The base plate 33 (FIG. 4), which in turn is attached at an angle to the support strut 32, engages in the area above the lower transverse profile 37 and is thereby secured against displacement in the longitudinal direction. Because the upper cross section 38, 41 is separated from the lower cross section 37, 40, the distance between said upper and lower cross sections 37, 38 and 40, 41 is also somewhat larger, so that the area open at the top is larger is than in a box section which is essentially rectangular in cross section. This makes it possible to push support struts 32 with very large base plates 33 under the holder arrangement even when the holder arrangement is in an inner position on the bearing plate 21 (FIG. 3). FIG. 3 shows the upper edge 25 of the cross strut 22. In the exemplary embodiment in FIG. 12, this upper edge 25 is displaced further inwards in the direction of the inner cross members 8. As a result, the area hatched in FIG. 3 is somewhat larger in the area of the cross-section arrangement of FIG. 12, which facilitates loading and unloading and makes it possible in the first place for certain types of support struts.

The invention can also be described by the following methods:

In the method for transporting support struts 32 for fence elements using a transport pallet described above, the support struts 32 are pushed under the upper floor 5 for transport.

In this method, it can be provided that base plates 33 of the support struts 32 are rotated into a horizontal position for insertion into the lower transport region 29, so that the base plates 33 are located above the cross struts 22, 23 and the base plates 33 subsequently move into a vertical position be rotated or rotate by their own weight into a vertical position, so that they reach behind the upwardly oriented legs 27 of the upwardly open cross strut 22, 23.
