Description

The invention relates to a transport arrangement with a transport pallet and with shut-off elements according to the features of patent claim 1.

Shut-off in the context of the invention are in particular metal barrier. Such barriers usually have permanently installed, laterally projecting feet, so that the individual barriers can stand independently. There are also embodiments in which the feet must be retrofitted. The subsequent assembly of the feet is not very complex at first glance, but the structure is delayed significantly in a variety of barriers. The mining takes longer. The advantage is that the safety barriers can be transported close to each other during transport without the feet interfering with each other.

This is the case with fixed feet, which are usually pipes that project at an angle to either side or a pipe bend Problem that the barriers generally require more space during transport. This applies both in height and in width. Even if the feet are offset from each other so that two adjacent barriers in the longitudinal direction do not need to be offset from each other, but virtually congruent side by side, nevertheless results in an increased transport volume, as always space for the feet of the edge-side fencing is needed. As explained above, more transport volume is also required downwards, that is to say in the area of the fixed feet, since such barriers are more bulky.

It is known to transport such barriers standing or hanging. In the standing transport, the individual feet stand on a suitably sized transport pallet. So that the individual barriers do not fall off the transport pallet, the feet are in a kind of gutter. In order to compensate for manufacturing tolerances and differences in length or even to accommodate different types of barriers, such a channel must be correspondingly wide. The wider the channel or the transport pallet, the greater is the cost of materials. The weight and cost increase as the payload decreases.

The state of the art is the EP 0 309 694 A1 to call concerning a device in the form of a quadrangular container for transporting and / or storing flat goods. Such a container is provided for transporting and / or storing garments. The device is characterized essentially by a frame-like formed, provided at the corners of the longitudinal and transverse sides with pillars container, which in the upper part of a plurality of elements formed, height-adjustable in the vertical columns assembly for hanging receiving the garment and in the lower part Having the spaced-apart uprights attached and trained to settle on a pallet foot parts. Such a device is stacked and hinged ready-made goods can be combined to a minimum of space parallelogram.

By the DE 10 00 289 B includes a stackable pallet to the prior art. The loading plate is used in particular for the transport and storage of pressure-sensitive goods. To protect the pressure-sensitive goods has gone over to equip the pallet with upwardly directed supports, which serve to receive a further pallet. As a result, such pallets are stackable even in the loaded state.

A transport pallet for fence and / or shut-off elements counts through the DE 20 2006 012 275 U1 to the state of the art. The transport pallet for fence and / or shut-off elements provides longitudinal beams and cross beams, which form a horizontal, rectangularly configured support frame. On the support frame holder assemblies for plug-in receptacle of pipe ends of the uprights of fence and / or shut-off elements are provided. The fence and / or shut-off elements are arranged higher in a central region of the transport pallet than at least one fence or shut-off element which can be placed in an edge region of the transport pallet. In this arrangement, the fence and / or shut-off are not on the side over the transport pallet. The transport pallet must therefore be designed sufficiently large. The size of the transport pallet can negatively affect the payload.

In the FR 2 790 023 A1 A transport device for barriers is proposed in which the barriers are transported suspended over two floors. The hanging arrangement in two floors requires that a certain floor height can always be maintained. Such an arrangement is less flexible with respect to the inclusion of different barriers and usable only for a particular type of shut-off elements.

Finally, on the DE 202 14 323 U1 to point out, which discloses a sub-rack with a bottom part for receiving bark parts. The shelf sub-carrier is characterized in that on or above the Floor part at least two juxtaposed storage rooms are arranged, of which a first storage space is so large that several foot plates for beacons have space in it and a second storage room has juxtaposed jack parts for other bakery parts. Above these two adjacent storage rooms, another storage room can be created by an intermediate floor. The intermediate floor is height adjustable. In addition, on the supports over which the intermediate bottom is adjustable in height, laterally projecting side parts are attached via the size of the intermediate bottom. These stand outwards and serve to receive support rods with jack parts arranged thereon. Gate-like beacons can be accommodated on these jack parts with two stand-up bars which are horizontally spaced from each other and protrude downwards from a correspondingly long horizontal information sign. Such beacons may also be referred to as roadblocks or barriers. The disadvantage of this is that this shelf subcarrier must be as large in terms of its external dimensions of the side parts as the shut-off elements to be carried. The fixation on the feet requires a cost of materials that can subsequently affect the payload.

Proceeding from this, the present invention seeks to provide a transport arrangement for stationary transport of shut-off elements, with which it is possible to transport at high payload and low material usage and shut-off elements of different dimensions.

The invention solves this problem by a transport arrangement with the features of claim 1.

The subclaims relate to advantageous developments of the invention.

The transport arrangement according to the invention comprises a transport pallet with shut-off elements, with side members and cross members of the transport pallet forming a horizontal, rectangularly configured supporting frame. Of the Support frame is intended to carry the shut-off in a vertical position, that is in a vertical orientation. The shut-off elements have a greater width than the support frame, so that the support frame is located between the feet of the individual shut-off elements projecting downwards over a lower edge of the shut-off elements. The support frame itself has feet in its corner, which are height adjustable relative to the support frame, so that the shut-off elements rest with their lower edges during transport on the support frame. Due to the height adjustability of the feet, the transport pallet for shut-off elements with divergent dimensions, in particular with regard to the feet, can be used.

The invention is based on the idea not to carry the individual shut-off elements in the area of their feet, but in the region of the lower edges of the respective support frame. The feet do not stand on the support frame. This eliminates a gutter or a lateral boundary to prevent the feet from slipping off the transport pallet completely. This saves material. The weight drops. The transport pallet is cheaper to produce. At the same time, the payload increases.

The feet of the shut-off elements can to some extent serve as a barrier to prevent slipping off the transport pallet. The feet in the sense according to the invention must necessarily be a projection projecting downwards over the lower edge.

With the transport pallet according to the invention but also shut-off elements are transportable, the feet are removable. Such shut-off elements usually have on their underside a projection, for example a sleeve into which the actual foot can be inserted. The term foot in the context of a shut-off means in the context of the present invention therefore each over the lower edge down projecting projection which is part of a foot or can be coupled with a removable foot. Functionally, however, each further protruding down over the lower edge Protrusion form a boundary that prevents slippage of the shut-off elements of the transport pallet. But the shut-off can also be considerably wider than the transport pallet, so that the feet are at a distance to the longitudinal beams. For this case, holders may be provided on the transport pallet.

The height adjustment of the feet of the support frame makes it possible to completely lower the support frame during loading, so that shut-off elements do not fall over when loading, but still stand on their own feet. The shut-off elements are now positioned over the support frame. Only when the support frame is raised and the distance between the support frame and the lower edge of the shut-off elements is reduced, the shut-off come into contact with the lower edge and are raised overall. Until then, the support frame is still unloaded.

After lifting the feet of the support frame are extended so far and locked relative to the support frame, that when stopping the loaded transport pallet, the individual shut-off elements no longer come into contact with the ground. In addition, this ensures that the feet of the shut-off elements are not damaged when settling, or that in a stacked arrangement, the below-mentioned shut-off elements are not damaged.

In an advantageous embodiment, the feet of the transport pallet are arranged below the plane of the support frame part of supports which serve above the plane of the support frame to lean against the shut-off elements to be transported thereto. The shut-off can be secured by the supports against lateral slipping and tipping over. For this purpose, suitable holders are attached or attachable to supports. The shut-off would fall over without such support, since they are no longer on their own feet.

It is also conceivable to provide fixed supports. Removable supports, which are inserted from above into the support frame, are also possible. When not in use, detachable supports can be inserted horizontally into the longitudinal struts of the transport frame so that they do not protrude upwards but are safely stowed away. To fix the position, the supports can additionally be screwed to the supporting frame when they are in the longitudinal members.

It is considered appropriate to form the feet as part of the supports. Since the feet have only a relatively short length, and because the transport pallet preferably has a very low height, the feet form in the retracted state quasi a part of the supports, which are above the plane of the support frame. In the extended state, so to speak, the supports shorten, in which the lying above the plane of the support frame part is displaced downwards and thus functionally assigned to the base of the support. Supports may have a receptacle for stacking the individual transport assemblies at their upper ends, which serves to receive the feet of another upper transport pallet arranged on the lower transport pallet. The stacking of the transport arrangements is possible both in the loaded and uncharged state. The length of the supports including the feet is preferably at least as large as the height of the shut-off elements to be transported.

The height adjustment of the feet and the supports is particularly advantageous because it allows an adjustment of the transport pallet to different types of shut-off. Shut-off elements from different manufacturers have different heights from each other.

The supports are preferably adjustable in height only in a fixed predetermined division, which does not exclude that it may well be within the scope of the invention to adjust the supports infinitely. The height adjustment should, however, be uniform, so that all feet are loaded evenly in the loaded state. In addition, a uniform height adjustment is important if multiple transport arrangements to be stacked on top of each other. Here it must not come to tipping over the horizontal. It is therefore preferred marks on the division provided that facilitate a uniform height adjustment. It may, for example, be a color mark.

Preferably, the supports in the region of the feet have a plurality of longitudinally spaced openings, which are engageable with openings on the support frame guide sleeves. About these openings, the feet can be coupled by means of insertable into the support frame coupling means height adjustable with the support frame. The coupling agent is in particular a locking pin. Such a socket pin can be secured against falling out. For this purpose, conventional securing means may be provided. The securing means are, in particular, plug-in fuses, e.g. Cotter pins. Of course, more expensive securing means such as e.g. Screw connections possible. Preferably, the coupling means is locked captive by a plug-and-turn connection in the manner of a bayonet closure after insertion into the opening on the sleeve holding the support. For this purpose, a projection may be arranged on the coupling means, that is on the socket pin, as e.g. a welded tab that always rotates the coupling means due to the gravity of the tab so that the tab faces down. The tab can engage in this position, for example, in a pocket which is formed on the sleeve. As a result, it is ensured solely by the force of gravity of the tab, that the locking pin can not shift itself axially.

While the tab as part of the plug-and-turn connection can pivot the plug pin by gravity in a particular direction and at the same time engages in a pocket, it is also conceivable to provide an additional weight to the socket pin. The weight is to be arranged eccentrically, so that the plug pin or the tab of the plug pin rotates in the desired position. The weight may in particular be part of a handle which is at the end of the Plug pin is attached. In particular, the weight is a square rod which is connected to the latter, in particular welded, at an angle to the longitudinal axis of the plug pin. In addition, if the opposite corners of such a square bar in the longitudinal direction of the pin, the square bar can be easily gripped even when the locking pin is in the inserted position.

In addition, the tab or pocket provided for receiving a tab of the bayonet lock may be configured such that a retainer securing means can not be connected to the coupling means unless the coupling means has been fully inserted into the pocket.

Advantageously, the transport pallet is transported by means of a forklift or other suitable stacking device. For this purpose, the longitudinal members may be formed as hollow profiles, in which a fork of a stacking device can be inserted. The overall height of the longitudinal member is correspondingly very low.

The longitudinal members in the form of hollow profiles, must not be closed circumferentially over the entire length. It is also conceivable to use only U- or C-shaped profiles, which are provided in the particularly loaded area with striking plates, so that the U or C profiles do not spread or buckle. Particularly high loads occur in such transport pallets in the region of the ends of the longitudinal struts. Therefore, the strike plates can have a higher wall thickness than the preferably downwardly open U or C profiles, from which the longitudinal beams are made. This requirement-appropriate design makes it possible to produce the transport pallet according to the invention in lightweight construction, that is, with less material use and thus to keep the material costs low.

The cross beams, which connect the side members together, no special loads with uniform loading of the transport pallet take up. Carrying components are therefore the side members. On the side rails and the guide sleeves for the supports are attached. The transport pallets are in particular welded structures made of steel, which have been galvanized for corrosion protection.

With the transport pallet according to the invention, a maximum number of shut-off elements can be transported if the feet and supports are fastened as far as possible to the ends of the support frame. However, with feet of the shut-off elements protruding on both sides, this leads to the feet projecting beyond the end faces of the transport pallet. This can cause damage to the feet of the barrier elements during loading operations. It is therefore possible not to attach the guide sleeves to the outermost ends of the longitudinal members, but alternatively or additionally at a certain distance thereto, this distance is preferably dimensioned so large that the feet of the shut-off do not project beyond the end faces of the transport pallet. The front side is limited by the outermost end point of the transport pallet. This can coincide with the end of the longitudinal member.

The fact that the feet of the barrier elements do not protrude beyond the end faces, the cargo can to the size of the loading area of a means of transport, such. to be adapted to a truck.

But it is also conceivable that the longitudinal member is still a distance element upstream. The spacer is to prevent a forklift fork is moved too deep into the side members, which could lead to damage to the shut-off. The spacing element can be a simple sheet metal or flat iron projecting from the front side of the transport pallet. The spacer element can also help to protect the coupling means used in the openings of the guide sleeves when they project beyond the end faces of the transport pallet.

In a further advantageous embodiment of the invention, the columns can be made split. For example, the supports via a suitable Connection be performed telescopically, so that a change in length of the supports is possible. It is also conceivable a separation of columns and feet. For example, the height-adjustable feet can be mounted in end guide sleeves of the support frame, while the supports are arranged in further guide sleeves, to prevent the feet of the shut-off elements protrude end over the transport pallet. The arrangement of such pairs of guide sleeves is of course also possible if the supports are designed in one piece with the feet.

Theoretically, it is also conceivable to arrange more than two or four guide sleeves per longitudinal side of the transport pallet. For example, a fifth guide sleeve in the middle of the longitudinal sides of the transport pallet can serve to secure the shut-off elements when the transport pallet is only half loaded. The supports can therefore be repositioned as needed.

The shut-off elements are in particular those with vertical bars. For very wide shut-off elements, in which the feet do not bear against the longitudinal members of the transport pallet and which thus lack lateral guidance through the longitudinal members, it is provided to place additional means for aligning the blocking elements on the supports. These can be fixed installations on the columns. It is also conceivable, however, to assign the supports releasably determined means for aligning or fixing the shut-off elements.

In the fixed means for alignment are in particular in the direction of the shut-off protruding projections which engage at least in the first shut-off and this secure transversely to the longitudinal direction of the transport pallet against displacement. Such an element may be referred to as a holder.

The holder may additionally be designed such that it also prevents a displacement of the locking element engaged with the holder in the longitudinal direction of the transport pallet. For example, a bracket may be provided on the holder, which is pivotable behind the shut-off elements. One such bracket can be oriented, for example, vertically when placing the first Absperrelements so that it engages with the holder between adjacent, vertically extending rods of the shut-off. By pivoting for example 90 degrees in a horizontal position, the bracket then grasps behind the bars. The bracket may have end-side, pointing to the bars offsets, so that the bracket can not turn back automatically by contact with the rods. The turning back can also be hampered by suitable spring means, which allow easy adjustment of the bracket, but not an independent shift. As a suitable spring means spring washers are considered.

With regard to the releasably associated means for fixing or aligning the shut-off elements on the transport pallet, in particular tension straps may be mentioned by means of which the shut-off elements are secured. The straps are guided around the supports and through the barriers.

In this context, it is considered advantageous if devices are provided on the supports, which prevent slippage of the applied tension straps. For this purpose, a suitable projection is formed on each of the supports. In particular, the projection is a strap, which can also serve as a handle to grip the supports, for example, to adjust them in height or to take the supports completely out of the guide sleeves.

A tension belt, which has been pulled by such a bracket strap, can slide neither up nor down from the support and allows a secure fixation of entrained shut-off elements, especially if the transport pallet is not fully loaded. The strap tabs are preferably arranged in the upper end region of the supports at a distance from the end face. Of course, it is possible to provide per support also several such strap tabs, for example, to attach straps at different heights.

If additional hooks are attached to the uprights, the strap straps can also be used to hang a support that is currently not needed by means of the strap strap on another support. This situation may arise when the supports are removed at one end of the transport pallet while the side members are blocked by stacking forks, e.g. because the support frame is intended to serve as a kind of extended fork lift. In this case, a pair of supports remain on the support frame and the other pair of supports can be hung in the first pair and so carried.

In a further advantageous embodiment of the invention, the upper sides of the longitudinal beams are configured slip-resistant. It can be a covering or a profiling. It can be provided individual ribs, pin or ridge-shaped elevations or a triangular profiling, which prevent the lower edges of the shut-off elements slip. Such over the top of the longitudinal bars projecting projections need not necessarily be attached to the top of the longitudinal beams, but may also be fixed to the longitudinal sides of the longitudinal bars. The important thing is that they protrude over the top.

An optimal loading of the transport pallet according to the invention results when the individual shut-off elements are close to each other, wherein the gap between the individual shut-off elements tends to zero. In today's standard galvanized steel tube constructions with laterally projecting feet, this means that the feet on the lower tube must not be set too high, otherwise rest the feet on the lower tube of the adjacent shut-off. There would be a gap left. Accordingly, the laterally protruding feet in the form of tubes in the invention are preferably set so low that touch the lower horizontal tubes of the shut-off as possible over the entire length. Since the attachment points of the laterally projecting feet thereby move together and a higher bending moment is introduced into a smaller area, with smaller diameter tubes, such with to use larger wall thicknesses. Optionally, the pipes are also auszusteifen with a cross connection. A gusset plate is also conceivable in order to achieve a sufficient strength in the region of the lower edge of the shut-off elements.

With the transport arrangement according to the invention but also shut-off elements are transportable, which have only one side feet, namely so-called Rangelgitter. Also so-called Radrenngitter can be transported, the feet are arranged offset from each other so that they can be placed close together and transported (stackability).

The transport arrangement according to the invention is very variable with regard to the securing possibilities for the shut-off elements to be carried along. The support frame serves as a universal support frame with which supports of different configurations can be coupled. The supports therefore do not necessarily have to be straight and in particular perpendicular to the longitudinal members. In specially configured shut-off elements, it is also conceivable that supports are angled or bent or in addition have such angled or cranked components, which are attached as it were as an adapter to a rest otherwise straight in particular perpendicular support. The supports can for this purpose have suitable coupling options such as. e.g. Holes. The supports themselves can also stand in a straight, but in an angle deviating from 90 degrees to the longitudinal member.

Preferably, however, the supports are straight and designed in particular as a load-bearing hollow profiles so that they on the one hand have a relatively low weight, but still a high buckling resistance to ensure the load capacity when stacking the transport arrangements one above the other.

In particular with regard to a partial loading of the transport pallets, it is conceivable to additionally provide holding elements which can be coupled to the longitudinal carriers. These holding elements can, for example, with the Side members are braced to prevent slippage of the lower ends of the entrained shut-off elements. This can be done for example according to the principle of a screw clamp. The holding elements can be provided, for example, with a plug-in receptacle. In such a plug-in receptacle can spatially horizontally located next to the longitudinal members, so do not protrude above the side member. Only by inserting a locking device into the plug-in receptacle is the holding function in relation to the shut-off elements fulfilled. The holding element is thus more flexible, since different, and adapted to the respective shut-off barrier means can be coupled to the holding element. It is even conceivable to dimension the plug-in receptacle as well as a guide sleeve, so that a support or a detachable part of a support can be inserted into the plug-in receptacle. So that the locking device does not slide down through a downwardly open plug-in receptacle, a clamping means, such as a bolt, by means of which the holding element is clamped to the side member, engage under a bottom opening of the socket. The clamping device then blocks this opening.

It is also conceivable to couple the adjacent barrier elements, for example in the region of their feet, in particular to brace them against one another. The tension of the shut-off causes the subsequent shut-off against the previous shut-off no longer laterally and preferably not in the longitudinal direction of the side rail moves. If the first, the supports adjacent shut-off is fixed on the holder and bracket, and subsequent shut-off can be safely positioned on this first, fixed-position shut-off. The shut-off elements engage via their adjacent holding feet, preferably into one another, so that a positive connection results from the first to the last shut-off element. The last shut-off element can in turn be secured by a holder against lateral displacement, so that with this end-side positional orientation of the entrained shut-off elements a secure connection of all shut-off elements is created.

The transport of unloaded and not equipped with the supports transport frame can be facilitated by stacking tabs are arranged on the transport frame, which protrude above the support frame and align an overlying support frame relative to the lower support frame and secure against lateral slippage in all directions. The stacking tabs are mounted in particular in the region of the transverse beams. The stacking tabs can be arranged in pairs and at an acute angle to the vertical, so that it comes to a centering when settling an upper transport frame on the lower transport frame.

• Figur 1 eine Transportanordnung für Absperrelemente in der Draufsicht;
• Figur 2 die Transportanordnung der Figur 1 in der Seitenansicht
• Figur 1 zeigt eine Transportpalette 1 für Absperrelemente 2. Aus Gründen der Übersichtlichkeit ist nur ein einziges derartiges Absperrelement 2 dargestellt.

The invention will be explained in more detail with reference to an embodiment shown in the drawings. It shows:

• FIG. 1 a transport arrangement for shut-off in plan view;
• FIG. 2 the transport arrangement of FIG. 1 in the side view
• FIG. 1 shows a transport pallet 1 for shut-off 2. For the sake of clarity, only one such shut-off element 2 is shown.

It can be transported on a transport pallet 1 up to 50 such shut-off elements.

The transport pallet 1 comprises two mutually parallel longitudinal members 3, 4. The longitudinal members 3, 4 are connected at their ends via a respective cross member 5, 6 with each other. The longitudinal members 3, 4 and cross members 5, 6 form a horizontally configured rectangular support frame 7. The support frame 7 is intended to receive the shut-off elements 2 in a vertical arrangement. The shut-off elements 2 have a greater width B than the support frame 7. The shut-off elements 2 are configured essentially rectangular and have at their lower edge 8 (FIG. FIG. 2 The feet 9, 10 are located laterally of the transport pallet 1 and thus on the outside of the longitudinal bars 3, 4. The longitudinal bars 3, 4 are thus located between the feet 9, 10, wherein the lower edge 8 of the shut-off elements 2 rests on the longitudinal bars 3, 4. Here are the feet 9, 10 down over the support frame 7, as based on the FIG. 2 can be seen. Nevertheless, the feet 9, 10 do not touch the floor, since below the support frame 7 in each case in the corner regions of the transport pallet 1 feet 11 are. The feet 11 form the lower ends of supports 12, as in FIG. 2 can be seen.

The supports 12 have at their upper ends 13 each have a receptacle 14 which serves to receive the feet 11 of a further arranged on a lower transport pallet 1 upper transport pallet 1. That is, the transport pallets 1 can be stacked one above the other.

The supports 12 are height adjustable in a fixed predetermined division. For this purpose, a plurality of openings 15 are provided in the region of the feet 11, which are spaced apart in the longitudinal direction of the feet 11. The openings 15 in the feet 11 can be brought into coincidence with openings 16 in guide sleeves 17, which are penetrated by the supports 12 and the feet 11, respectively. In this position, in the respective aligned openings 15, 16, a coupling means 17 are used in the form of a plug pin. The coupling means 18 and the locking pin can be held captive by a not-shown plug-in rotary connection (bayonet lock) after insertion into the openings 15, 16 on the guide sleeve 17.

Out FIG. 1 It can be seen that in addition to the guide sleeve 17, a further guide sleeve 17a is provided, which is also on the outside of the longitudinal beams 3, 4 but at a small distance from the end guide sleeves 17. The guide sleeve 17a also serves to accommodate the supports 12. For reasons of clarity, the guide sleeves 17a were not shown in the image plane on the left, but only drawn to the right. The guide sleeves 17a are spaced so far from the front ends of the transport pallet 1 or the longitudinal members 3, 4 that the feet 9, 10 of the shut-off elements 2 do not protrude beyond the end faces of the longitudinal members 3, 4.

The additional guide sleeves 17a are placed in adaptation to the geometry of the shut-off elements 2 to be transported. Therefore, other positions for the guide sleeves 17a are possible.

In addition, spacer elements 23 are provided on the front sides of the longitudinal members 3, 4. These are flat irons, which point in the longitudinal direction of the outer walls of the side members 3, 4 and prevent a forklift fork from being lowered too deeply into the side members 3, 4. This not only the entrained shut-off elements 2 are protected, but also any coupling means 18 which are arranged in the guide sleeve 17 ( FIG. 2 ). The coupling means 18 not shown in detail can be used both for the guide sleeve 17 and for the respective associated guide sleeve 17 a. About a flexible element, in particular in the form of a link chain, the coupling means 18 may be captively connected to the transport pallet 1.

As a special feature of the transport arrangement according to the invention it should be noted that the supports 12 are completely removable from the guide sleeves 17, 17a. If this is done at two supports 12 at one end of the transport pallet 1, the transport pallet serves as an extension of a forklift fork. The transport pallet can therefore be pushed completely under juxtaposed shut-off elements 2 due to their flat design. Finally, the missing supports 12 are mounted again and the transport pallet 1 can be raised. The supports 12 are lowered, so that the feet 11 are extended. The supports 12 are then locked by means of the coupling means 18 in a precisely marked height. The coupling means 18 are secured against loss.

Since the individual shut-off elements 2 can have a substantially greater width than the transport pallet 1, a holder 19 with a bracket 20 is provided on the supports 12 in each case. The holder 19 projects in the direction of the shut-off elements 2 and engages between it in this Embodiment vertically extending rods 21. As a result, at least the first shut-off element 2 does not slip sideways. Subsequently, the bracket is pivoted by 90 degrees relative to its initial position, so that the ends of the bracket 20 engage behind the bars 21 of the shut-off element 2. The ends of the bracket 20 are slightly rounded in the direction of the rods 21. Due to the play between the rods 21 of the shut-off element 2 and the bent bracket, the bracket 20 can be easily adjusted by hand. The clamping effect is due to the special design of the bracket 20 automatically. The bracket 20 has due to the bend, which leads to a support on the rods 21, not the tendency to independently pivot back to its original position, but certainly fulfills the holding function ( FIG. 2 ). Such holder 19 and bracket 20 may be present on each support 12.

In addition, a strap strap 22 is provided on the supports 12 in the upper third. The arcuate or C-shaped bracket tab 22 serves on the one hand as a handle to remove the individual supports 12 from the guide sleeves 17. In addition, a flexible tensioning means, in particular a tensioning belt, can be guided through the strap flap 22 in order to secure the blocking elements 2 on the transport pallet 1. The handles or strap tabs 22 are located on the opposite side of the holder 19th

From the representation of FIG. 2 It can be seen that the longitudinal beams 3, 4 are formed as hollow profiles. It is in this embodiment, rectangular profiled box sections, which are provided for receiving a fork of a stacking device. In a modification to the illustrated embodiment, it is possible to use only downwardly open C-profiles instead of a rectangular profiled box section, which is completely closed on the circumference, wherein the particularly loaded areas of the C-profile are closed by strike plates.

The particularly stressed areas include, in particular, the end regions of the longitudinal struts 3, 4. In this case, correspondingly strong striking plates would have to pass over a length of for example 150 to 200 mm may be arranged. The wall thickness of the strike plates can be chosen to be 5 mm compared to 2.5 mm of the C-profile correspondingly large, so that the C-profiles do not deform and in particular the loads of stacked loaded or unloaded transport pallets can be transmitted. At a distance from end-side strike plates further individual strike plates can be provided.

The overall height of the longitudinal members 3, 4 is not greater than the overall height of the cross member 5, 6 and the guide sleeve 17 and is in particular less than 100 mm, in particular 80 mm. The cross members may be circumferentially closed or open profiles. Also, it could be profiled sheets, such. B. zig-zag sheets.

FIG. 2 shows how the support frame 7 is raised relative to the ground level and the individual shut-off elements 2 can be raised accordingly. In order to load the shut-off elements 2 on the transport pallet, the support frame 7 can be lowered by releasing the coupling means 18. When a stacker has raised the support frame 7, the front supports 12 removed from the stacker can be pulled out and pushed into the side rails 3, 4. It is also possible to pull the rear pillars 12, which are adjacent to the stacker, somewhat high in order to be able to lower the support frame 7 more deeply overall. Then, the support frame 7 as an extended fork juxtaposed shut-off, such as a forklift from below engage and pick up from the ground. The supports 12 are then repositioned and locked.

On the supports 12, a hook 24 is disposed in each case in the region of the upper end. The hooks 24 serve to receive a support 12 from the other end of the transport pallet 1 if the side members 3, 4 are occupied by a forklift fork. As a result, all supports 12 always remain on the transport arrangement, even if they are not needed at the moment.

In addition, stacking tabs 25 are arranged on the transport pallet 1. The stacking tabs 25 serve to secure unloaded and not provided with supports 12 support frame 7, which are stacked flat on top of each other to prevent slipping. The stacking tabs 25 are in this embodiment, the outer sides of the cross member 5, 6, and thus in the region of the end faces of the support frame 7. The cross member 5.6 are slightly offset inwards, so that the stacking tabs 25 not on the spacer elements 23 (if present) or the end faces of the side members 3, 4 protrude so as not to be damaged. The stacking tabs 25 are bent in a manner not shown to serve as a centering when stacking the support frame 7.

In FIG. 1 Furthermore, a holding element 26 is shown, which is attached purely by way of example to the lower of the two side members 4. The holding element 26 is detachably connected to the longitudinal member 4. It is held by clamping forces. When the clamping force is released, the holding element 26 can be displaced in the direction of the arrow P in the longitudinal direction of the longitudinal member 4. The clamping force is applied via a clamping screw 28 indicated only, which is located below the longitudinal member 4 and extends to a plug-in receptacle 27. The plug-in receptacle 27 is in this case so large, so arranged and oriented with respect to the insertion as one of the guide sleeves 17, 17 a. In the socket 27, a locking device, not shown, similar to a post, are releasably inserted, which prevents slippage of entrained shut-off elements at partial loading.
