Abstract

The invention relates to a fixing system, for connecting a folding container, made from corrugated cardboard, to a base plate, for example a palette base or a stacking container top, characterised in that clips (4) and/or clipping bars (5) are arranged on the free edge of the folding container (1), with clip jaws (15), arranged on a clipping base (18) and one or more tabs (6), on the clipping base roughly opposite the clipping jaws, extending beyond the clipping base. Clipping teeth (16) are arranged offset to each other on both clip jaws of a clip of a clip bar, the length of which roughly corresponds to the width of the clipping base or which extend beyond the same. Guide angles (12) with plug slots (14), corresponding to the tabs, are arranged, for example, on the palette base (10) or the container top (11), such that said guide angle forms a guide groove (13) with the edge of the baseplate, for example, the palette base or the container top.

Description

fastening system

The invention relates to a fastening system for connecting a folding container made of heavy corrugated cardboard to a base plate, for example a pallet base, or a cover plate of a stackable flat container.

In the prior art, stackable plywood stackable containers, which are built on a pallet, are known among other things. In these designs, the individual side walls are held together by angle brackets which are guided on the outside, laterally over the edges of two abutting side walls, and are rigidly connected to the two side walls. Tabs are attached to the upper and lower edges of the side walls, which are positioned and anchored in special plug connections arranged on the pallet or the lid. In addition to the high weight and the high material costs (including for the approx. 6 to 8 mm thick plywood panels), such designs are disadvantageous, in particular the high production costs, and also the relatively complicated handling for assembling the stacking containers, since a large number of loose components are individually assembled Need to become.

This large number of loose components requires not only a large storage space in the transport state but also that a large number of individual parts during the transport of the unassembled container to the customer, ie before the assembly, must be held together securely, otherwise the

There is a risk that the connecting elements in particular will be lost.

In addition, the structure also requires a high degree of skill, since the attachment of the angle bracket is relatively complicated.

Due to the large number of metal strikes, there is also a high level during loading and handling of the fully assembled container

Risk of injury.

Another major disadvantage of plywood containers is that due to the easy deformability of the plywood panels, the side walls of the containers bend under load with increasing container size, i.e. become unstable. Another disadvantage of container designs made of plywood with angle brackets is the high risk of break-in and theft, since the plywood containers in the state of the angle brackets can be easily broken open and then emptied when they are filled with transport goods.

Therefore, only limited insurance coverage is provided for such plywood transport packaging.

On the other hand, folding packaging in the manner of box pallets with folding containers made of heavy corrugated cardboard are prescribed in the prior art, the

Floor, which usually consists of folding parts adjoining the side walls, screwed onto the boards of a pallet made of wood or a similar material, or is fastened by means of plug-in or clamp connections, as prescribed, for example, in EP 1 142 793 A1.

The bottom of the container can be open / covered with a lid.

A disadvantage of these designs is that the containers are filled out after filling

Heavy corrugated cardboard must also be attached to the pallets by means of straps so that they do not detach from the pallets when filled during transport.

In other designs, "lids" are attached to the pallets, then folding containers that are open on one or both sides are attached to these "lower lids" adjusted and, if necessary, in turn covered by a further “upper cover”.

In order to facilitate space-saving storage before use, it is generally proposed to fold the “packaging housing” onto the pallet, so that the pallets on which the folding containers are then built are also well suited for their transportation in the preassembled state.

In order to ensure sufficient stability of the cardboard boxes placed in this way

To ensure sidewalls, box pallets of this type generally need additional vertical supports, for example

Cardboard sheets, such as u. a. prescribed in EP 0628 489 B1, and / or

Wooden poles are reinforced / stiffened, which on the one hand the

Increase manufacturing costs significantly and at the same time the assembly processes become more complicated.

Another major disadvantage of such, with in mounted on pallets

Lids "inserted" side walls, for example also in the EP

0619795 B1 presented design is that, for example, a force acting horizontally on the upper edge of the pallet box causes the carton to tip and thereby unilaterally come out of its guidance in the

Pulls out the "lid" attached to the pallet base.

Inevitably, for example, the small parts to be transported fall out of the pallet box.

For this reason, it is also imperative to stabilize these additionally with circumferential belts with these pallet box designs. This inevitably requires increased manufacturing and assembly costs.

Another, very material-intensive design of a transport container is proposed in US 005123541 A and EP 0577763 B1. At this

In design, elastic clips are arranged on the lower and upper edge of the side wall structure, which snap into clip receiving slots arranged on the pallet base or on the lid of the transport container. Another disadvantage of this embodiment is that it is also of a high level

Manufacturing effort is required to attach the clips to the

Precisely punch out the edges of the circumferential side wall, which are to be arranged one above the other, in order to fasten the clips in a functionally reliable manner. In addition, this design is in turn very vulnerable to theft, since the elastic clips can be easily pushed out of their locking grooves and the box can be opened, so that these containers are either only used for internal transport, or in turn also have to be secured with straps.

In GB 2089 316 A a design of containers is made

World cardboard folding containers with locking elements described above. This

Locking elements are arranged on the edge of the cardboard box and are inserted into associated locking bushes arranged in the cardboard boxes.

The disadvantage of this design is that it is only for small format

Pallet boxes are suitable, since the plug connections specified there can only be subjected to low loads.

In addition, the arrangement of the clamps on the edge of the cardboard box requires a very high level of production expenditure, since the clamp tines arranged on the clamps and penetrating the cardboard box and the opposite clamp plate follow on the outer surface of the opposite clamp plate

Push through must be bent.

These bent-over clamp tips result in particular during the

Assembly and disassembly of the folding containers pose a high risk of injury.

Another variant of attaching a corrugated cardboard to a

Wooden pallet is known from DE PS 21 42 823.

Here, sheet metal triangles are arranged on the wooden pallet

Place the folding box on the pallet, bend it and clamp it through the side walls of the box just above the bottom of the box. With this fastening variant, however, the carton in the edge area is weakened so much that when the carton is subjected to tensile stress, the carton tears off the pallet, so that the pallet must also be secured to the carton by means of straps in this variant.

The invention is therefore based on the object of eliminating the abovementioned disadvantages of the prior art and of developing a fastening system for a stable, theft-proof connection of a folding container made of heavy corrugated cardboard with a base pallet or a cover plate of a stacking container, which is simple and inexpensive to manufacture and at Minimal use of cardboard stabilizes the folding container in its edge area so that it ensures a stable and secure connection between the folding container and the base pallet or the cover plate without the arrangement of additional circumferential bands, and thereby the folding container by the connection according to the invention to the base or cover plate so stabilized that this has a high bending and tilting stiffness even under extreme operating conditions and also guarantees a high level of theft security with high functional reliability and reliability, so that the stacking container is very suitable even for air and sea freight, whereby the stacking container is characterized by a small transport volume, a low transport weight and few assemblies (no small parts) in the transport state, which is uncomplicated and quick, safe and reliable with just a few hand movements , can be connected to each other under heavy loads.

According to the invention, this object is achieved by a fastening system for connecting a folding container (1) made of heavy corrugated cardboard to a base plate, for example a pallet base (10) or a cover plate (11) a flat stacking container by means of the folding container (1) and on the pallet base (10) or the cover plate (11) arranged, interlocking connecting elements, which is characterized in that on the free edge of the folding container (1) brackets (4) and / or clamp rods (5) with clamp cheeks (15) arranged on a clamp base (18) and one or more tabs (6) arranged on the clamp base (18) approximately opposite one another on the clamp base (18) and projecting beyond the clamp base (18) ) are arranged, and on the two clamp cheeks (15) of a clamp (4) / a clamp rod (5) mutually offset clamp prongs (16) are arranged, the length of which corresponds approximately to the width of the clamp base (18), or projects beyond it, whereby on the base plate, for example the pallet base (10), or the cover plate (11), guide brackets (12) with the tabs (6) assigned plug slots (14) are arranged such that the guide brackets (12) with the Form a guide groove (13) at the edge of the base plate, for example the pallet base (10) or the cover plate (11).

According to the invention, the guide groove (13) serves to receive the free edge of the folding container (1) stiffened by clamps (4) and / or clamp rods (5). This is inserted into the guide groove (13) in such a way that the tab (s) (6) projecting beyond the clips (4) or clip bars (5) are inserted through the plug-in slots (14) in the guide bracket (12).

As a result, the folding container (1) is fixed exactly on the base plate, for example the pallet base (10), or on the cover plate (11). Then the brackets are positioned exactly in the guide grooves

(4) or clamp rods (5) are pulled into the guide grooves (13) by means of tensile loads on the tabs (6), or the folding container (1) is pressed firmly into the guide groove (13) with its clamps (4) or clamp rods (5).

The tabs (6) are then bent around the guide brackets (12), which means that the brackets (4) or the clamp rods

(5) stiffened free edge of the folding container (1) in the on the pallet base (10) or the cover plate (11) arranged guide groove (13) is clamped and locked.

As a result of this simultaneous stiffening of the free edge of the folding container according to the invention by means of clips (4) or clip bars (5) in connection with the inventive tensioning of the free edge stiffened according to the invention in the bottom plate, for example the pallet bottom (10) or the cover plate ( 11) arranged guide grooves (13) at the same time a stable, theft-proof connection of the folding container to a bottom pallet or a cover plate of a stacking container is ensured, which is simple and inexpensive to manufacture.

In addition, by the solution according to the invention, the folding container is stabilized and clamped in its edge area with minimal use of cardboard so that it guarantees a stable and secure bond between the folding container and the base pallet or the cover plate, even without the arrangement of additional circumferential bands, the folding container is stabilized at the same time by the connection according to the invention with the base plate or the cover plate in such a way that the folding container itself is stiffened in such a way that it obtains high bending and tilting rigidity and is therefore also suitable for very extreme operating conditions.

The solution according to the invention also ensures a high level of theft security with a high level of functional security and reliability, so that the stacking container is very well suited even for air and sea freight.

The stacked container according to the invention is characterized at the same time in the preassembled transport state by a low transport volume, a low transport weight and a few assemblies (without loss-prone small parts), which can be safely and reliably connected to one another in a simple and quick manner to form a very heavy-duty structural unit. The solution according to the invention is simple to manufacture and also very inexpensive to manufacture.

Particularly advantageous embodiments of the solution according to the invention are presented in subclaims 2 to 7

It is preferred that a tab hole (7) is arranged in the middle of the tab (6). This achieves optimal handling of the system according to the invention, so that, for example, the tensile forces and bending moments can be transmitted very advantageously to the tabs by means of an assembly hook.

It is also advantageous that a relief bore (19) is arranged on the base of the tab, in the transition area to the clamp cheek (15) on both sides of the tab (6). This avoids stress cracks in the transition area to the clamp cheek (15).

It is also advantageous that a stiffening rib (17) is arranged on both sides of the tab (6) from a clamp cheek (15) over the clamp base (18) to the other clamp cheek (15). This results in a high stability of the clamp cheeks (15) with minimal use of material, so that they are evenly aligned after tensioning on the edge of the box.

It is also advantageous that the tips of the clamp tines (16) are curved toward the clamp edge. In connection with the length and arrangement of the staple tines (16) according to the invention, this causes the tips of the staple tines (16) to penetrate the opposite wall of the staple (15) during the stapling process, the compression of the staple in the edge of the folding container ) are bent upward like a claw, so that a tear-proof clamp assembly is produced opposite the edge of the heavy corrugated cardboard. It is also advantageous that the tab (6) is curved with the clip (4) closed, or with the clip bar (5) slightly outward, out of the plane of the folding container wall, so that the tab (6) is better Insert into the slot (14) and at the same time operate more easily and can be braced on the guide bracket (12).

It is also advantageous that, instead of the folding container made of corrugated cardboard, a folding container made of plastic hollow chamber panels can be used, which can also be combined, for example, with plastic-coated or plastic base or cover panels.

In such designs, the stacking containers according to the invention can also be used in the food industry.

Further details and features of the invention emerge from the following description of the exemplary embodiment according to the invention in conjunction with the claims and the drawings relating to the solution according to the invention.

The invention will now be explained in connection with nine graphic representations.

Figure 1 shows the spatial exploded view of a stacking container according to the invention in partial section with two possible designs of the fastening system according to the invention in the assembled state. At the

Folding container 1, which was cut to length, for example, from an "endless" sheet of heavy corrugated cardboard and whose cut edges are clamped together at the overlap 3, the wall surfaces were separated from one another by creases 2, so that the folding container 1 easily changed into the rectangular one shown in FIG A plurality of clips 4 or clip rods 5 according to the invention were attached to the free container edge with the tabs 6 arranged thereon that the guide brackets 12 form a guide groove 13 with the edge of the base plate, for example the pallet base 10 or the cover plate 11. For assembly, the free edge of the folding container 1 is inserted into the guide grooves 13. At the same time, the clamps 4, or to the Clamping rods 5 arranged tabs 6 inserted through the slots 14.

Of course, the folding container can also be a container made of heavy corrugated cardboard provided with a folding lid, the lid of which consists of folding parts adjoining the side walls. Such a folding container is arranged analogously on the floor pallet, but is closed at the top by clipping the folding parts adjoining the side walls.

FIG. 2 shows the spatial representation of the stacking container according to the invention according to FIG. 1, in the filled and now closed state. The tabs 6 of the clamps 4 or clamp rods 5 arranged on the folding container 1 were positioned exactly in the guide grooves by pushing through the plug-in slots 14 of the guide bracket 12 arranged on the bottom of the pallet 8 or the cover plate 11.

The clamps 4 or clamp rods 5 are then pulled into the guide grooves by tensile loading on the tabs 6, or by pressing on the opposite edge, the folding container 1 is pressed firmly into the guide grooves with its clamps 4 or clamp rods 5.

Subsequently, the tabs 6, as shown in FIG. 2, are bent around the guide bracket 12, as a result of which the free edge of the folding container 1 stiffened by the clamps 4 or the clamp rods 5 is braced in the guide groove arranged on the pallet base or the cover plate 11 and simultaneously locked ,

As a result of the simultaneous stiffening of the free edge of the folding container according to the invention by clips 4 or clip rods 5 in connection with the bracing according to the invention of this free edge stiffened according to the invention in the guide grooves 13 arranged according to the invention on the base plate, for example the pallet base 10 or the cover plate 11, a stable becomes Connection of the folding container with the floor pallet or the Guaranteed cover plate of a stacking container, which is simultaneously simple and inexpensive to manufacture.

Figure 3 shows the clip 4 in the open, not yet assembled state. On the brackets 4 18 bracket cheeks 15 are arranged on a bracket base. The bracket cheeks 15, approximately opposite, are arranged on the bracket base 18, a tab 6 projecting beyond the bracket base 18. On the two clamp cheeks 15 of a clamp (4), clamp prongs 16 are arranged offset to one another, the length of which slightly exceeds the width of the clamp base 18. The tips of the clamp tines 16 are curved toward the edge of the clamp. In connection with the length and arrangement of the clamp tines 16 according to the invention, this means that during the clamping process, the compression of the clamp into the edge of the folding container, the tips of the tines after the penetration of the folding container wall, the heavy corrugated cardboard, are bent upward like claws on the opposite side of the clamp cheek, so that a tear-proof clamp assembly is generated.

A tab hole 7 is arranged in the middle of the tab 6. This achieves optimal handling of the system according to the invention, so that the tensile forces and bending moments can be transmitted very advantageously to the tabs during the assembly of the container, for example by means of an assembly hook.

A relief bore 19 is arranged on both sides of the tab 6 on the base of the tab, in the transition region to the clamp cheek 15. Stress cracks in the transition area to the clamp cheek 15 are thereby avoided.

A stiffening rib 17 is arranged on both sides of the tab 6 and runs from one clamp cheek 15 over the clamp base 18 to the other clamp cheek 15. These stiffening ribs 17 bring about a high stability of the clamp cheeks 15 with minimal use of material, so that the Clamping cheeks 15 are aligned on the edge of the cardboard after tensioning.
