Abstract

The invention relates to a pallet attachment (1) for detachable attachment to a transport pallet, in particular a standard pallet, such as a Euro pallet or a one-way pallet, comprising a pallet connection base (4) for placing on top of a transport pallet and two railing frames (7) attached to the pallet connection base, each with an upper rail run section (27), and two upper run struts (9) which couple the upper rail run sections to one another in such a way that an upper circumferential rail run is formed.

Description

The invention relates to a pallet attachment, such as supporting railing attachment, for attachment to a transport pallet, in particular to a standard pallet, such as a Euro pallet or a disposable pallet, for the transport of plate-like goods with a high center of gravity, especially of furniture parts such as cabinet walls, shelves, etc. and a pallet attachment as a stacking tower, for stacking transport pallets, in particular standard pallets, such as europallets or disposable pallets.

The transport of plate-like goods takes place as far as possible via transport units, in particular containers, swap bodies, semitrailers, which are manually / loosely loaded and unloaded. This leads to a high amount of time when loading and unloading the container. Remedy can create the loading on transport pallets that are loaded with floor conveyor, such as forklifts, pallet trucks in the transport. However, the length and the high center of gravity of plate-like goods complicate their loading on transport pallets. This problem is partly addressed by the fact that horizontal structures are attached to one-way pallets made of wood, to which the plate-like goods ajar and subsequently secured with securing aid, in particular with straps. In doing so, securing the plate-like goods with e.g. Straps also at an increased cost. Furthermore, this solution causes permanent acquisition and disposal costs for the transport pallets.

A multi-purpose solution is over DE 20 2005 018 491 U1 known. Therein, a pallet attachment with two side walls is described, which are arranged opposite one another on a transport pallet and are fastened detachably to the transport pallet via a fixing device. The side walls consist of a plurality of vertically extending struts, which are interconnected at the upper end of the struts via a transverse strut, wherein the transverse struts of the side walls are spaced parallel to each other. In the resulting space transport goods can be leaned against the crossbars.

When loading loaded transport pallets with the known pallet attachment leaning against the pallet attachment transported goods, especially plate-like goods with a high center of gravity, can fall off the transport pallet and be damaged. Furthermore, transport goods can slip on the transport pallet and shift the center of gravity of the loaded transport pallet, so that during loading the transport pallet together with goods to be transported can fall off the floor conveyor such as a forklift. In order to prevent falling of individual transport goods or the entire transport pallet, the goods to be transported have to be conveyed via securing aids, such as e.g. Tension straps are clamped to the pallet attachment, which again leads to an increased expenditure of time. During the return transport of unloaded transport pallets, the high side walls of the pallet attachment lead to a large space requirement, so that the transport capacity of a means of transport, e.g. Container, is reduced. The space required for the return transport can be reduced by disassembling the pallet attachment from the transport pallet and loading it separately. To prevent slippage of the pallet attachment within a means of transport, e.g. In the container to prevent, this in turn must be fixed in the container, which in turn increases the time required for the entire transport process. In the storage of transport pallets and the well-known pallet attachment must be weighed between a space-saving and a time-saving solution. The pallet attachment can be stored mounted on the transport pallet, which leads to an increased storage space requirement. Furthermore, in this solution, an increased time required for transport to the storage room and during transport from the storage room to a loading station, since the large space requirement of mounted on the pallet transport pallet leads to the fact that only a few transport pallets can be transported at once. If the pallet attachment is transported separately from the transport pallet between the warehouse and the loading station and / or between the unloading station and the warehouse, several individual parts must be transported for a transport pallet with a pallet attachment, which again leads to an increased expenditure of time.

It is an object of the present invention to overcome the disadvantages of the prior art, in particular to provide a supporting railing attachment and a stacking attachment for transport pallets with which the time required for the safe transport of plate-like goods can be reduced with a high center of gravity, the time required in particular for Transport process, preferably for the entire transport process, starting with the outsourcing of transport pallets and Traggelanderaufsätzen or Stapelaufsätzen on the loading and unloading of transport pallets with transport goods, especially with plate-like goods, to the return transport and storage of transport pallets and the supporting railing attachments or stacking attachments should be reduced.

This object is solved by the features of independent claims 1, 2, 14 and / or 23. In a first development aspect, a pallet attachment, such as a carrying rail attachment, is provided for releasable attachment to a transport pallet, in particular a standard pallet, such as a europallet or a disposable pallet. This comprises a pallet connection base for placement on a transport pallet top, two support walls attached to the pallet connection base, such as railing racks, each having an upper railing run section and two overflow struts coupling the upper land run sections together to form an upper circulating railing run.

In an alternative or additional approach, a pallet attachment for particular detachable attachment to a transport pallet, in particular a standard pallet, such as a Euro pallet or a disposable pallet, is provided. A standard pallet has fixed dimensions in the longitudinal and transverse direction. The pallet attachment according to the invention may be adapted to the dimensions of the standard pallet to ensure a positive placement of the pallet attachment on the pallet, without using special fasteners such as screws, nails or the like when mounting on the mounting pallet. In particular, the pallet attachment to be releasably attached to the transport pallet, so that a preparation and removal of the pallet attachment without tools is possible. For dimensioning the pallet attachment according to the invention, the dimensions of a standard pallet should be incorporated here by reference to the corresponding regulations, such as DIN regulations (for example EN 13698-1, EPAL), as a reference in this patent application. The same applies to the structural design of the pallet, which is often formed with the top of the transport pallet forming longitudinal plates, such as wooden boards, in particular support plates, which forms a distance of a few centimeters between them, wherein on an underside of the longitudinal plates transverse strips, insbesondre transverse intermediate boards or Crossbars are attached to secure the longitudinal plates. The gaps, such as longitudinal gaps, between the longitudinal plates serve to receive fork-like engagement elements of a tilt protection to ensure the detachable, but tilt-free attachment of the pallet attachment to the transport pallet.

The pallet attachment according to the invention has a pallet connection base, which preferably consists of at least two base carriers. The pallet connection base, in particular the at least two base carriers, are preferably dimension-matched to the short edge sides of the standard pallet and arranged there so that they do not extend beyond the transport pallet in the horizontal direction protrude. A minor board is acceptable. The at least two base supports may be coupled to each other via lower-side connecting arms, but are preferably separate from each other and therefore may be mounted separately. The at least two base carriers are located on the short edge of the transport pallet on the top. The base supports preferably each have at least two fork-like, in particular in the assembled state of the pallet attachment horizontally extending gripping arms extending between the longitudinal plates of the transport pallet and with a below or approximately at the level of the transport pallet top, in particular transversely extending transverse bar to move in the assembled state in the horizontal direction of the transport pallet towards each other and / or to avoid tilting of the transport pallet. The pallet connection base is designed to be stored on the top of the transport pallet. From the pallet connection base extend at least two separable support walls, such as railing racks, substantially vertically from the pallet connection base and the transport pallet top substantially vertically to initiate lateral transport forces of the laid on the transport pallet, such as furniture, non-positively in the transport pallet and transfer ,

According to the invention, the pallet attachment comprises a support wall strut or reinforcement arranged above the transport pallet upper side, which is preferably realized by two struts extending in particular in the horizontal direction. Preferably, the struts realizing the support wall bracing or stiffening form the above-mentioned overflow struts. The support wall may be formed as a flat continuous wall. However, in the preferred embodiment, the support wall is an open railing frame having vertically extending railing columns and preferably a railing overflow. Preferably, the railing overflow is the above-mentioned upper railing running section. The support wall strut may preferably form the upper side, but may alternatively be arranged above the upper side of the pallet, but in the vertical course between the upper edge of the support wall and the upper side of the pallet. Preferably, the support wall extends at least 50 cm, 80 cm, 100 cm above the pallet top, with the support wall struts extending substantially horizontally in a range of 30 cm to 1 m above the pallet top. Preferably, the strut is elongated on the support wall top to form a kind of upper railing run. According to the invention, the supporting wall strut is constructed in such a way that it forms the support walls with one another, forming a particularly closed, continuous adhesion, such as a ring closure coupled. The supporting walls form part of the ring closure. In the case of a longitudinally extending pair of horizontal struts, the force-locking connection is formed by the support walls and the pair of struts. It should be understood that the struts may be oriented transversely or longitudinally when the support walls are disposed on the respective long or short side of the transport pallet.

In a plan view, the force-lock is positioned to substantially follow the outer dimensions of the transport pallet. In the case of plan view, a course corridor around the outer dimension of the transport pallet (in the case of a top view) of ± 20%, ± 10%, ± 5% can be formed in which progress corridor the opposing support walls and the support wall bracing extend.

When looking at the vertical, the force-locking connection, in particular the supporting wall strut, should not be located closer than 30 cm to the top of the transport pallet, in particular between 30 cm and 200 cm, 30 cm and 150 cm, preferably between 50 cm and 150 cm. It is clear that the support wall strut is above the top of the transport pallet, wherein the force lock can also in particular in the region of the support walls at the level of the transport pallet top, even below, can be performed to form the ring closure.

With the measure according to the invention an extremely stable pallet attachment is provided, which can support long and bulky goods safely, so that a significant reduction of the loading time of the loaded transport pallet can be achieved for example in a container or a truck. It was found that with the stiffening of the transport pallet attachments a reduction of 50% to 80% of the loading time can be achieved. The classic loading machines, such as forklifts, can be worked faster. In addition, inexperienced staff can be used to load various goods, such as bulky goods, such as furniture components.

For embodiments in which the base carriers are designed to be placed on long sides of a transport pallet, in particular to be suspended, the following information on the longitudinal direction relates in each case to the transverse direction and information on the transverse direction in each case to the longitudinal direction. However, it has proven to be advantageous to design the base support to be mounted on short sides of a transport pallet, because thereby a greater distance between the base supports for the later-described fixation of railing racks and overflow struts is formed.

In a preferred embodiment of the present invention, the upper struts and the Gelanderlaufabschnitte are each spaced parallel to each other. The overflow struts preferably extend in the longitudinal direction and parallel to one another. A distance of the upper struts in the transverse direction forms the railing width.

In a preferred embodiment of the present invention, two strut connections are secured to the top of the railing racks, in particular fixedly connected or welded, to which the overflow struts are releasably attached. In the context of the present invention, parts attached to one another can either not be detached from one another without destroying them, or the detachment of the parts requires the use of tools. The phrase affixed to the top of the rail racks, in the context of the present invention, means that the strut connections are vertically spaced from the base support, particularly in the vertical direction at the top of the base supports. Preferably, the strut connections are secured to the upper handrail sections of the railing racks. The strut connections are preferably fastened on the outside, more preferably at the ends of the overflow struts, to the upper railing running sections. In each case a pair of strut connections, each of which a strut connection is attached to a railing frame, are opposite to each other, in particular in the longitudinal direction opposite, arranged.

The distance A corresponds to the distance between a complementary to the strut connections formed portion of the spacer leg and the complementary to the strut connections formed portion facing away from the longitudinal edge of the upper strut. So that the distance between the upper struts described below can be increased or reduced exactly by the distance A, the outer wall of the upper strut and the outer wall of the portion of the spacer leg formed at a distance A complementary to the strut connections should be dimensioned equal. Deviations in the dimensioning of the outer wall of said parts result in that the distance between the overflow struts is increased or decreased approximately by the distance A.

FIG. 1 shows a mounted on a transport pallet 3 support railing attachment 1 according to the invention in a perspective view. FIG. 2 is a side view of FIG. 1 , FIG. 3 is a front view of FIG. 1 , FIG. 4 is a top view of FIG. 1 , In the in the FIGS. 1 to 4 illustrated embodiment, two base supports 5 are mounted on opposite sides of the transport pallet 4. At each base support a railing frame 7 is mounted with an upper railing running section 27. The upper railing running sections 27 are coupled to each other by two overflow struts 9, so that a circumferential railing run is formed. In the illustrated embodiments, the base 5 on the short sides of the Transport pallet 3 attached. The base supports 5 are in each case on the outer edge 13 of the short sides. On the base supports 5, two column terminals 15 are fixed, which extend in the vertical direction upwards. Furthermore, two railing columns 12 are respectively attached to the railing running sections 27 which extend downwards in the vertical direction V. The railing racks 7 are each mounted on the railing columns 12 to the column terminals 15 of a base support 5. In the transverse direction on the outer sides of the upper Landlaufaufabschnitte 27, a strut port 37 for attaching the overflow struts is mounted in each case. The strut connection is designed as a hollow cylinder.

In the longitudinal direction on the outer sides of the upper runners 9, a spacer leg 19 is mounted in each case. The spacer legs 19 extend orthogonally to the overflow strut 9. Two spacer legs 19 and an overflow strut 9 each form a U-shape. At the spaced from the upper strut ends of the spacer legs 19 connecting leg 29 are attached. The connecting legs 29 are fastened at a distance A from the upper strut 9, wherein the distance A is the distance in the transverse direction between the outer strut 9 facing the outer edge of the connecting leg 29 and the connecting leg 29 facing away from the outer edge of the upper strut. Thus, the distance of each one spacer leg to the other can be increased or decreased exactly by the distance A, the outer wall of the upper strut and the outer wall of the connecting leg should be the same size. Deviations in the dimensioning of the outer wall of said parts result in that the distance between the overflow struts increases or decreases approximately by the distance A. The connecting legs 29 extend orthogonally to the spacer legs 19. In addition, the connecting legs extend orthogonal to the overflow strut 9. In the present embodiment, the connecting legs 29 are formed by hollow cylinders open at the end faces. The spacer leg 19 is formed as a hollow cylinder, which is open at the end face which is opposite to the upper leg of the strut 9 spaced side of the spacer leg. The inner diameter of the spacer legs 19 and the connecting leg 37 corresponds approximately to the outer diameter of the strut connections 37. In this case, the inner diameter of the spacer legs 19 and the connecting leg 29 is 0.5 mm larger than the outer diameter of the strut connections. As a result, a Vakant the upper struts when attaching to the strut connections are largely avoided. At the same time attached to the railing racks 7 upper strut 9 is largely immovable in the horizontal direction.

For the strut connections 37, as well as for the spacer legs 19 and the connection legs 29, other shapes can also be used. For example, the spacer legs 19 and the connecting legs 29 configured as a cylinder of solid material be mounted inside of configured as a hollow cylinder strut connections. The shape does not necessarily have to be cylindrical. It can also elliptical and angular shapes for the strut connections 37, spacer legs 19, and connecting leg 29 are used. However, it has been found that, in particular, the combination described above leads to lower production costs and minimizes the risk that the upper struts jam when attached to the railing racks.

The upper strut brace 9 can be attached to the railing racks 7 in a vertical position and in two horizontal positions. In the FIGS. 1 and 3 the left upper strut 9 is mounted in the vertical position. In the vertical position, the spacer legs 19 extend vertically upwards. The in the FIG. 1 and 3 Pictured right upper strut 9 is mounted in an inwardly inclined horizontal position. In the inwardly inclined horizontal position of the upper strut 9, the spacer legs 19 extend from the strut connections 37 horizontally, in particular in the transverse direction Q, in the direction of the oppositely mounted upper strut 9. Alternatively, the upper strut 9 in an unrepresented outwardly inclined horizontal position of the railing frames. 7 be attached. In the outwardly inclined horizontal position of the upper strut 9, the spacer legs of the strut connections 37 extend horizontally, in particular in the transverse direction Q, in the opposite direction of the oppositely mounted cross member.

With the exemplarily described upper struts 9 and strut connections 37 five distances between the upper strut can be adjusted. Three of these distances are in the FIGS. 1 . 8 and 9 shown. FIG. 8 and FIG. 9 show embodiments of the present invention, which is characterized by the arrangement of the overflow struts 9 of the embodiment in the FIGS. 1 to 4 differ. The smallest distance between the overflow struts 9 is by an arrangement as in FIG. 8 shown reached. In FIG. 8 Both upper struts are mounted in the inwardly inclined horizontal position of the railing racks. The next larger distance between the overflow struts is through an arrangement as in FIG. 1 shown achieved. Therein, the left upper strut is mounted in the vertical position and the right upper strut 9 is mounted in the inwardly inclined horizontal position. The third largest adjustable distance between the overflow struts 9 is in FIG. 9 shown. Therein, both upper runners 9 are mounted in a vertical position on the railing racks 7. The second largest distance is achieved by an upper strut 9 in vertical position and by an upper strut 9 in the outwardly inclined horizontal position. The largest distance between the overflow struts 9 is achieved by two upper struts in the outwardly inclined horizontal position. The amount of the five adjustable Distances between the overflow struts can be determined by the distance between the strut connections 37 and the distance A.

In the present embodiment, the strut terminals 37 are fixedly connected to the rail running portions 27. But they can also be releasably attached, for example via screw connections or connectors, to the upper railing track sections 27. In combination with a plurality of mounting possibilities of the strut connections 37 on the railing running sections 27, the variability in the adjustment of the distance between the overflow struts can thus be further increased. Alternatively or additionally, additional strut connections 37 could also be mounted in the transverse direction Q at a distance from the existing strut connections 37 in order to increase the variability in the adjustment of the distances between the overflow struts 9.

A particular advantage of the embodiment shown here of the upper struts 9 and strut connections 37. is that the position of the upper strut can be changed by simply turning about an extending in the longitudinal direction L strut axis SA. As a result, the distance between the overflow struts 9 can be adjusted quickly and variably even in confined spaces.

The in the FIGS. 1 to 16 illustrated transport pallets 3, 6 are standard pallets, namely europallets, which have a dimension of 800 x 1200 mm. The transport pallet has six pillar blocks 33 which are secured together by longitudinal bottom boards 43 at the bottom and transverse intermediate boards (crossbars) 53 for forming the support structure of the transport pallet 3, 6. The support structure forms lateral engagement openings 63 in the transverse direction Q and longitudinal direction L, in the forklift tines (not shown) can retract. The support of the transport pallet 3, 6 is formed by five extending in the longitudinal direction L support plates or boards 73 which define adjacent to one another in the longitudinal direction L extending longitudinal gap 83 which is open to the top of the pallet. The longitudinal gaps 83 extend in the longitudinal direction L from one of the short sides of the transport pallet (800 mm) to the opposite side. The longitudinal extension of the longitudinal slots should be dimensioned such that the tines 21 described later a tipping guard 11 can be positioned in the longitudinal column.

In the in the FIGS. 1 to 4 as well as 8 and 9 illustrated embodiments of the supporting railing attachment the railing run is designed rectangular. The upper struts extend in the longitudinal direction and parallel to each other. In the transverse direction, the upper struts 9 are spaced parallel to each other by a Geländerlaufbreite GB. The railing sections 27 extend in the transverse direction and parallel to each other. In the longitudinal direction, the railing running portions 27 are spaced apart by a Geländerlauflänge GL parallel to each other. The Geländerlauf extends to a Gelanderlaufhöhe GH. The Gelanderlaufhöhe GH corresponds in the vertical direction V the distance between the upper edge of a Gelanderlaufabschnittes 27 and the lower edge of a base support 5. The Geländerlaufhöhe GH, the Geländerlauf width GB and the Geländerlauf lengths GL span a rectangular space AR for transporting goods T, as in FIGS. 1 to 4 shown on.

In the present embodiments, the distances between the upper struts form the Geländerlaufbreite GB in the transverse direction Q. Transport goods T, in particular plate-shaped transport goods with a high center of gravity, can be supported on the railing run sections 27 and / or on the overflow struts 9.

In FIG. 2 It can be seen that the base supports 5 are attached to the short sides of the transport pallets. The base support 5 are mounted in alignment with the outer edges 13 of the short sides of the transport pallets. The base support are designed as L profile with a horizontal wall 25 and a vertical wall 35. The vertical wall is flush with the outer edge 13 of the short sides of the transport pallet. The column terminals 15 extend substantially from the outer edge 13 of the short sides of the transport pallets in the vertical direction V. The distance of the column terminals to the outer edge 13 of the short side is given by the thickness of the vertical wall 35 of the base support. 5

The railing columns 12 are mounted in alignment with the column terminals 15, so that they extend substantially from the outer edges 13 of the short sides of the transport pallets in the vertical direction V. The attachment of the railing racks 7 at the outer edges of the (lower) transport pallet 3 allows the distance between the railing run sections 27 to be made as large as possible. The Geländerlauflänge GL corresponds substantially to the length of a transport pallet on which the railing frame is placed. The difference to the length of a transport pallet results from the extension of the railing running sections 27 in the longitudinal direction L and the thickness of the vertical wall 35 of the base support 5. Due to the large rail run length GL, a large receiving space AR for goods T can be provided.

The FIGS. 5, 6 and 7 show different stages of construction when mounting a supporting railing attachment according to the invention, as in FIG. 8 is shown. In FIG. 5 is a first base support 5 at the outer edge 13 of a first short side of a (lower) transport pallet 3 attached. A second base support is located in an intermediate position for attachment to the outer edge 13 of a second short side of the (lower) transport pallet 3. For attaching the base support to the transport pallet, these are tilted vertically from a horizontal position above the base support 5 vertically down, so that on the Base support attached anti-tipper 11 a transverse intermediate board 53 of the (lower) transport pallet 3 can be attached to the transport pallet. The anti-tip 11 is in detail in connection with the FIGS. 18 and 19 described.

In FIG. 6 two base supports 5 are attached to the outer edges 13 on opposite short sides of the (lower) transport pallet 3. A first railing frame 7 is attached to one of the base supports. A second railing frame 7 is in an intermediate position for attachment to the second base support 5. The railing frame 7 is vertically attached to the base support 5 from above. When attaching the railing frame 7 to the base support 5, the railing columns 12 are telescopically attached to the column terminals 15. For this purpose, lower railing column sections 22 are formed complementary to the shape of the column connections 15. The column terminals 15 are described in detail in connection with the FIGS. 18 and 19 described. The lower railing column sections 22 are described in detail in connection with FIGS FIGS. 20 to 22 described.

In FIG. 7 are two at the outer edges 13 of opposite short sides of a transport pallet (3) mounted base support 5, two mounted on the oppositely mounted base supports 5 railing racks 7 and a first attached to the railing racks 7 upper strut 9 shown. A second upper strut 9 is shown in an intermediate position when attached to the railing racks 7. The upper strut 9 is attached vertically from above to the railing racks 7. The upper leg strut 9 is attached to the strut connections via sections 37, 29 of the upper leg strut that are complementary to the strut connections 37. The complementarily formed sections 19, 29 of the upper strut are telescopically attached to the strut connections 37. In the illustrated embodiments, the complementary formed connections by spacer legs 19 and / or by connecting leg 29, as in connection with FIG. 1 explained, trained. In FIG. 7 the upper strut 7 shown in the intermediate position is attached to the railing racks 7 in the horizontal inclined position. By attaching the second upper strut 9 to the railing racks 7 is an inventive railing frame, as in FIG. 8 represented, formed. The overflow strut 9 may be rotated about a longitudinally extending strut axis SA prior to attachment to the strut connections 37. The strut axis SA can, as in FIG. 7 represented, along the two connecting legs 29 extend. Turning 90 ° clockwise around the Strut axis SA, the upper strut 9 is set in the vertical position. If it is attached after the strut connections 37, then an inventive support railing attachment, as in FIGS. 1 to 4 represented, formed. In case that also in FIG. 7 already attached upper strut 9 is placed in a vertical position prior to attachment, an inventive support railing attachment, as in FIG. 9 represented, formed.

In FIG. 10 an embodiment of a stacking cap 1 according to the invention is shown, which is mounted on a transport pallet. Therein, two base supports 5 are respectively attached to opposite sides of a transport pallet (3). The base supports are respectively attached to the outer edges 13 of the short sides of the transport pallet. At the base supports 5 each two supports are attached. The four supports form a spacer on which a transport pallet can be placed. At the base supports 5 stops 16, 26 are mounted opposite each other in such a way that a displacement of an upper transport pallet in the longitudinal and / or transverse direction is blocked.

In the embodiment shown here, the supports are designed as attached to the base supports 5 column connections 15. In each case two attached to a base support column terminals 15 form a frame connection to each of a railing frame 7, as in FIG. 6 shown, can be attached. The column connections are detailed in connection with the FIGS. 18 and 19 described. The attachable to the frame connection railing racks 7 are described in detail in connection with the FIGS. 20 and 21 described. Complementary to the column terminals 15 formed lower railing column sections 22 are associated with FIG. 22 described in detail. When no rail racks 7 are attached to the pillar terminals 15, the pillar terminals 15 function as pillars for a spacer. Therefore, in the description of the FIGS. 10 to 16 the illustrated column terminals 15 referred to as supports and also provided with the reference numeral fifteen. It should be understood that the one-piece embodiment of the post and post is merely one preferred embodiment of the present invention. The column connections and the supports can also be designed as separate components.

On a base support in each case two supports 15 are mounted in the transverse direction spaced from each other to the base supports. The supports extend in the vertical direction V. The supports 15 are designed as a hollow profile. In the present embodiment, the supports 15 are configured as hollow cylinders. The upper end surfaces of the supports 15 form bearing surfaces 45, on which an (upper) transport pallet 6 can be stored.

In the present embodiment, the stops are attached to the supports 15. The attachment of the attacks on the base support 5 thus takes place via the supports 15. The stops are designed as sheets. On the supports 15 of a base support in each case a longitudinal stop 16 is mounted in the longitudinal direction L on the outer sides of the supports. In the present embodiment, the longitudinal stops 16 are fastened to the supports 15 via a spacer plate 36. The longitudinal stops project in the vertical direction V beyond the supports 15. Up to the upper end of the supports 15, the longitudinal stops 16 extend parallel to the pallet side to which the base supports 5 are attached. From the upper end of the supports 15 on the longitudinal stops 16, starting from a vertical plane, inclined by an angle α of the supports 15 away. The angle α is less than 90 °. In the present embodiment, the angle α is 15 °. The angle α is in FIG. 15 entered. Transverse stops 26 are mounted on the outside of the supports 15 in the transverse direction on two supports opposite each other in the longitudinal direction L. The transverse stops 26 extend parallel to the outside, to which the base supports 5 are attached. The transverse stops 26 do not project beyond the supports 15 in the vertical direction. In the present embodiment, the upper ends of the rams 26 fit flush with the support surfaces 45 of the supports. The planar connection of the upper ends of the transverse stops 26, the bearing surfaces 45 of the supports 15 are increased. The transverse stops 26 are chamfered from the upper end in the transverse direction to the outside and in the vertical direction downwards. Positioning and dimensioning of the supports 45 and the stops 16, 26 are described in detail in connection with the FIGS. 13 to 16 described.

At the base supports 5 are each two strut fixings 55 in the transverse direction Q spaced from each other attached. The strut fixings are designed as a hollow profile extending in the vertical direction. In the present embodiment, the strut fixings 55 are configured as hollow cylinders. In each case two strut fixings 55 are arranged opposite each other in the longitudinal direction. The strut fixations extend in the vertical direction V. The positioning and dimensioning of the strut fixings 55 are described in detail in connection with FIGS FIGS. 13 to 16 described.

The attachment of the base support 5 on a transport pallet, as in the stacking tower 1, via a tilt protection 11, in detail in connection with FIGS. 18 and 19 is described.

In FIG. 11 an inventive stacking attachment 1 is shown, on which a first railing frame 7 is fixed in a horizontal plane between the base supports 5. A second railing frame 7 is in an intermediate position for fixing in a horizontal plane between the base carriers 5 shown. For fixing a railing frame 7, this is inclined from a horizontal plane above the transport pallet (3) down to a base support 5, so that attached to the lower railing column sections 22 pins 32 in complementary to the pins 32 formed holes 42 in the base supports 5 can be inserted , In the present embodiment, holes 42 are formed in the pillars 15. Two holes 42 formed on two supports 15 fixed to a base support 5 form a pair of holes. The holes 42 of a pair of holes lie in the vertical direction at the same height. To fix a railing frame 7 to a transport pallet 3, two pins 32 of two lower railing column sections 22 are inserted into a pair of holes. The distance between two pins 32 of a support frame 7 corresponds to the distance between the holes 42 of a hole pair. In the present embodiment, a hole pair is formed on both base carriers, respectively. Another pair of holes is formed above the first pair of holes. The pairs of holes are spaced apart in the vertical direction in such a way that two railing racks 7 can be fixed one above the other between the base supports. By the execution of a respective pair of holes on both base supports 5, the railing racks 7 can be fixed in the longitudinal direction of two sides of the base supports. The pin-hole connection between railing frame and hole pair largely prevents a displacement of the railing frame in both transverse directions and in the longitudinal direction of the base support to which the pin-hole connection is formed. A displacement of the railing frame 7 in the transverse direction away from the base support 5, on which the pin-hole connection is formed, is largely prevented by the vertical wall 35 of the opposite base support 5. In a movement of the railing frame in the vertical direction on the opposite base support 5, the vertical wall 35 forms a stop for the strut connections 37. In a movement of the railing frame 7 in the vertical direction to the base support on which the pin-hole connection is formed, form the Support 15 a stop for related to FIG. 22 The railing racks 7 and the distance between the opposing base supports 5 are matched to one another such that there is a clearance in the longitudinal direction between the base supports 5 and a railing frame 7 fixed between the base supports. The clearance between the base supports 5 and a railing frame 7 fixed between the base supports is 5 mm in the embodiment described here.

In FIG. 12 a stackable article 1 according to the invention is shown, in which two railing racks 7 are fixed in horizontal planes lying between the base supports 5 and a first headrace strut 9 is fixed between the base supports. A second upper strut 9 is shown in an intermediate position when fixing between the base supports 5. To fix the upper strut between the two base supports 5, the upper strut is telescopically attached to the strut fixings 55. The strut fixings 55 are complementary to the Connecting legs 29 of the upper strut formed. In the present embodiment, the upper strut is fixed in the inwardly inclined vertical position between the base members. The base supports 5 are positioned on the transport pallet 3 such that the spacing of the strut fixings 55 in the longitudinal direction corresponds to the spacing of the connecting legs 29 in the longitudinal direction. In the fixed state of the upper struts 9 between the base members 5, the upper strut coupled to the base support. By coupling the base support 5 by means of the overflow struts 9, the stability of the stacking attachment 1 is increased.

The positioning and dimensioning of the supports 15 and the stops 16, 26 in the present embodiment will be described below with reference to FIGS FIGS. 13 to 16 described. FIG. 13 shows a stacking attachment 1 according to the invention, in which the base support 5 are mounted on opposite short sides of the (lower) transport pallet 3. Between the base supports two railing racks 7 and two overflow struts 9 are fixed. FIG. 14 shows the stacking tower 1 from FIG. 13 on which an upper transport pallet 6 is stored. FIG. 15 shows a side view of 5 stacked stacking attachments, as shown in FIG. 13 are shown. FIG. 16 shows a front view of FIG. 15 ,

The supports 15 of a base support 5 are transversely positioned on the base supports 5 such that, when a base support 5 is attached to the short side of a transport pallet, the supports 15 are transversely positioned above a downwardly open engagement opening 63 of the (lower) transport pallet 3, respectively are. With such a positioning of the supports 15, the supports 15 engage in the engagement openings 63 of an (upper) transport pallet 6, which is deposited on the stacking attachment 1. The distance in the vertical direction between the support surface 45 of a support 15 and the lower edge of the base support 5 is referred to below as the column height SH. The height of the engaging holes on the short side of a transport pallet, which is formed in the present embodiment by the distance between the lower edge of a cross-board 53 and the upper edge of a column block 33, is hereinafter referred to as the engagement height EH. The stowage space height VH between two transport pallets arranged one above the other results from the difference between the support height SH and the engagement height EH. The column height SH of the base support 5 is adapted to the engagement height EH of transport pallets to be stacked one above the other so that the stowage space VH is large enough to accommodate two railing racks 7 fixed between the base supports 5 without the railing racks 7 touching the upper transport pallet 6.

The strut fixings 55 are transversely positioned on the base supports such that when a base support is attached to the short side of a transport pallet, the strut fixings 55 are positioned transversely above the engagement openings 63 of the (lower) transport pallet 3. The position of the strut fixtures 55 is adapted to the extent of a crosshead brace 9 in the transverse direction and the transverse extent of the engagement apertures 63 such that a top runner 9 attached to the strut fixtures 55 is spaced transversely of the column blocks 33 left and right from the engagement aperture. In the present embodiment, the overflow struts 9 are fixed in the vertical direction above the railing racks 7 fixed between the base supports 5. As a result of the described positioning of the strut fixings 55, the required column height SH or the required stowage space height VH can be reduced, since the overflow struts 9 can also project beyond the stowage space height VH without touching an upper transport pallet 6 placed on the supports 15. This allows stacking attachments, as in FIG. 13 be shown superimposed on each other to save space.

The positioning and dimensioning of the longitudinal stops 16 on the base supports is adapted to a predetermined positioning of the base support 5 in the longitudinal direction on a transport pallet and on the dimensioning of a aufzulegende on the supports upper transport pallet 6. The positioning of the longitudinal stops 16 is such that the transport pallet facing inside of the longitudinal stops 16 to the upper end of the supports 15 with the outside of an (upper) transport pallet 6, to which the base support 5 is mounted, aligned. In the present embodiment, the longitudinal stops 16 are fastened to the supports 15 via spacer plates 36. The thickness of the spacer sheets in the longitudinal direction is chosen so that the inside of the longitudinal stops 16 are aligned to the upper end of the supports with the outside of a transport pallet to which the base support is attached. The spacer plates 36 do not project beyond the supports 15 in the vertical direction. From the upper end of the supports 15, the longitudinal stops 16 are inclined away from the (upper) transport pallet 6 by the angle α in order to reduce the risk of tilting of the transport pallet when placing an upper transport pallet 6 on the supports 15. The part of the attacks, which projects beyond the supports 15 attacks from outside on a laid on the supports transport pallet. In the present embodiment, the longitudinal stops 16 engage the outer edge of the transverse intermediate boards 53 which are secured to the short sides of the transport pallet. Two attached to a base support 5 stops 15 prevent slippage of an upper transport pallet 6 in the longitudinal direction of the one base support. An additional two attached to the other base support 5 stops 15 prevent slippage of an upper transport pallet 6 on the other base support to.

The positioning and dimensioning of the transverse stops 26 on the base supports is adapted to the dimensioning of the engagement openings 63 of a transport pallet, which is to be placed on the supports 15 and on the positioning of such a transport pallet. In the present embodiment, the transverse stops 26 in the transverse direction each engage the inside of the outer pillar blocks 33 of an upper transport pallet 6. In the vertical direction, the transverse stops 26 connect planner to the support surface 45 of the supports 15, thus increasing the support surfaces 45 of the supports 15. The support surface 45 of the supports 15 engages from below to the outer transverse intermediate boards 53 an upper transport pallet 6. The transverse stops 26 are bevelled outwardly and downwardly from the upper end of the transverse stops 26. Due to the chamfer of the transverse stops, the risk of jamming when placing an upper transport pallet 6 on the supports 15 is reduced. By a pair of transverse stops which are longitudinally opposed to the base supports and each engage a vertical edge of a pair of longitudinally opposed column blocks, slippage of a transport pallet laid on the supports is blocked in the one transverse direction. By another pair of transverse stops which are longitudinally opposed to the base supports and each engage a different vertical edge of a pair of longitudinally opposed column blocks, slippage of a transport pallet placed on the supports 15 in the other transverse direction is blocked.

FIG. 17 shows an exploded view of a base support 5, a railing frame 7 and an overflow strut 9. Each two of in FIG. 17 shown base support 5, railing racks 7 and overflow struts 9 form a supporting railing attachment according to the invention. To form the carrying rail attachment, two base supports are positioned opposite one another. At each a base support 5, a railing frame 7 is mounted telescopically. In each case an upper strut is telescopically attached to the upper railing running portions 27 of the railing racks 7. This creates a circumferential railing run. In each case two oppositely positioned base supports 5 form a stacking attachment 1 according to the invention.

The attachment of the base support 5 to a (lower) transport pallet 3 via an attached to the base supports anti-tipper 11. The design, dimensioning and positioning of the anti-tip to the base supports is following with reference to FIGS. 18 and 19 described. FIG. 18 shows a perspective view of a base support. 5 FIG. 19 shows a side view of FIG. 18 , For tipping 11 of a base support 5, two prongs 21 are attached to the underside of the base support 5. In the present embodiment, the tines 21 are attached to the underside of the horizontal wall 25 of the base support. The tines 21 are spaced apart in the vertical direction parallel to each other and extend in Longitudinal direction. At an end of the tines 21 spaced from the base support 5, a lower tilting stopper 31 is vertically spaced downwardly and mounted longitudinally parallel to the tine 21. The lower tilt stop 31 in the vertical direction opposite part of the tine 21 forms an upper tilt stop 41. At the lower edge of the tine 21, a tine longitudinal stop 51 is attached. In the present embodiment, the lower tilt stopper 31 is fixed to the lower edge of the one tine longitudinal stopper 51.

The upper tilt stop 41, the lower tilt stop 31 and the one Zinkenlängsanschlag 51 form a U-shape, which is open on the side facing away from the base support. When attaching the base support 5 to a transport pallet, the base support 5 is suspended via the formed U-shape in a transverse intermediate board 53 of a transport pallet. Mounted or attached to a transport pallet, the anti-tipper surrounds a transverse intermediate board 53. The lower tilt stop 31 engages, as in FIG FIGS. 2 and 3 to see from below on a cross-board 53 at. The upper tilt stop 41 engages, as in FIG. 4 to see from above on a cross-board 53 at. By the upper tilt stop 41 tilting of the base support 5 is prevented on the transport pallet. Due to the lower tilt stop 31, tilting of the base carrier 5 away from the transport pallet is prevented.

The one tine longitudinal stop 51 engages, as in FIG. 2 to see on the vertical edge of a cross-board 53 at. The one tine longitudinal stop 51 largely prevents a displacement of the base support 5 in the longitudinal direction L to the transport pallet. Another tine longitudinal stop 61 is mounted longitudinally to the one tine longitudinal stop 51 spaced at the lower edge of the tine 21. Attached to a transport pallet, the further tine longitudinal stop 61 engages, as in FIG. 2 to see at the vertical edge of another cross-board 53 at. The further tine longitudinal stop 61 largely prevents slippage of the base carrier in the longitudinal direction away from the transport pallet. The tine longitudinal stops 51, 61 engage in each case via the vertical edge, which is remote from the other tine longitudinal stop, to the vertical edge of the transverse intermediate boards. The distance between the vertical edges of the tine longitudinal stops 51, 61, which are each facing away from the other tine longitudinal stop, is referred to below as Zinkenlängsabstand ZL. The tine longitudinal distance ZL is adapted to the longitudinal distance of the opposing vertical surfaces of the column blocks BL of a transport pallet to be placed on the supports 15. The tine longitudinal distance ZL corresponds approximately to the distance between the pillar blocks BL. In the present embodiment, the tine pitch ZL is 7.5 mm smaller than the distance BL between the column blocks of a transport pallet to which the base supports are to be attached. As a result, attaching the base support 5 at ensures a transport pallet in which there is a low risk of jamming, while ensuring only a small clearance between the tine longitudinal stops 61 and the column blocks, so that the base support 5 can be moved to a small extent in the longitudinal direction.

As in FIG. 2 can see the tine longitudinal stops 51, 61 and / or the lower tilting stops 31 in the vertical direction to the platen boards spaced horizontal surfaces, within a possible engagement opening for lifting device, such as the fork of a forklift. In a decentralized retracting of lifting device in said engaging openings, the lifting devices can come into engagement with the horizontal surfaces of the tine longitudinal stops, which can lead to a sudden tilting or jerking of the transport pallet in an attempt to lift this. Therefore, in a preferred embodiment of the invention, as in FIG. 19 indicated by the dashed lines the tine longitudinal stops 51, 61 and / or the lower tilt stops 31abgeschrägt. In particular, the tine longitudinal stops 51, 61 and / or the lower tilt stops 31 are chamfered in such a way that lower horizontal surfaces of the tine longitudinal stops 51, 61 and / or the lower tilting stops are preferably largely avoided in the possible engagement region of lifting devices. In addition, by the slanted tine longitudinal stops decentralized introduced into engaging holes lifting devices can be positioned by sliding along the slope more central to the transport pallet. The distance between the lower tilt stop 31 and the upper tilt stop 41 in the vertical direction KV is adapted to the height of the transverse intermediate boards 53 of a transport pallet to which the base support is to be attached. In the present embodiment, the distance KV is 3 mm greater than the height of transverse intermediate boards 53 of a transport pallet to which the base supports are to be attached.

Attached to a transport pallet, the tines 21 extend within the longitudinal column 83 of the transport pallet. The width of the tines in the transverse direction and the height of the tines 21 in the vertical direction is adapted to the geometry of the longitudinal column 83. The width of the tines 21 in the transverse direction is to be interpreted smaller than the width of the longitudinal column 83 in the transverse direction. The height of the tines 21 in the vertical direction is to be interpreted smaller than the height of the longitudinal column 83 in the vertical direction. In the present embodiment, the tines are formed in the vertical direction 2 mm smaller than the height of the longitudinal column 83 of a transport pallet to which the base support to be attached. In the transverse direction, the width of the tines 20 mm smaller than the width of the longitudinal column, to which the base support 5 are to be attached. The positioning of the tines in the longitudinal slots largely prevents displacement of the base carriers in the transverse direction.

The upper railing running section 27 has a plastic jacket in the circumferential direction. The stiffening strut 52 has a plastic sheath in the circumferential direction. In the present embodiment, the plastic sheath is a PVC sheath. At the locations of the upper railing running section 27, to which the frame connections 37 and the railing columns 12 are fastened, a corresponding section of the plastic jacket is excluded.

In the present embodiment, the stiffening strut 52 is formed at the ends connected to the railing columns 12 complementary to the railing columns. For the attachment of the stiffening strut 52 to the railing columns the railing columns are applied to the complementary shaped ends of the stiffening strut and welded around it. The strut connections 37 and the railing columns 12 are formed at the end connected to the upper railing running section 27 complementary to the upper railing running section 27. For the attachment of the railing columns 12 and the strut connections 37 to the upper railing running section 27, said parts are applied to the upper railing running section and welded to it all around.
