Description

Pet crate

The present invention relates to housings, racks,

Frame parts of wound and / or glued, multi-layer recycled paper layers and consumer goods that can be produced from these parts, such as transport boxes for high-quality goods.

In the international patent application WO 2009/141260 a tube system of wound recycled paper layers is described, which can be used for the production of shelves, walls, frames or containers, which in turn can be recycled without a costly disassembly into their individual parts and thereby a relatively good stability should have. For this purpose, it is proposed to form a pipe system from at least two outer cardboard tubes, which are formed from multi-layer wound and / or glued, recycled paper layers, wherein for the purpose of a stable and easily detachable connection of these two cardboard tubes these have at least two overlapping recesses, so that the two cardboard tubes are intermeshable with each other in such a way that they can be connected to one another by means of a connection rod or a connecting tube which passes through the recesses.

Basically, this is a construction that is already known from the field of hinge hinges in furniture already. The outer carton tubes still contain reinforcing tubes, which are inserted into the outer cardboard tubes and optionally glued to them. This design is also found in the area of the corner edges of transport boxes, which are formed according to the pre-published system.

CONFIRMATION COPY A first disadvantage of this pre-published system is that the corner edges are not stable enough, especially if one of the system formed by the system

Transport box with heavy goods to be filled, for example, with heavy bulk material or heavy heavy plate-like products such as flat screens, system elements for windows, etc.

A further disadvantage is that the cardboard tubes to be joined often have to have matching recesses which, in turn, all have to be sawn or punched. This represents a relatively large effort, which must be avoided.

task

In contrast, the object of the present invention is to develop the devices mentioned in the preambles of the claims such that they with a. As little effort as possible can be made and in particular in the edge region or in the connecting region of two struts have a significantly higher stability.

Brief summary and advantages of the invention

According to a first aspect of the present invention, an edge member of wound and / or glued (recycled) paper layers with at least two, chen the Außenkan ^¬ te of Kantenlements forming outer surfaces, two Stirnflä- and discloses at least two internal surfaces for a component to be produced, which in is characterized in that the edge element seen in cross section by its outer ^¬ surfaces an angled outer contour, wherein a Ers ^¬ ter and a second edge portion of the outer contour - preferably by respective pivoting relative to a predetermined Ritzungs- or Rillungslinie - in the interior of the Cross-section with each other and / or on the inner surface of the

Outside contour are fixed, whereby the end faces and the inner surfaces are formed. Preferably, the edge element can be produced as follows:

a) by a cross-sectional polygonal or rounded polygonal, wound tube, preferably of a quadrangular tube, the

b) in the longitudinal direction, on two opposite. lying on the sides of the cross-section provided scribe lines or grooves that allow pivoting of the adjacent surfaces to each other,

c) separated in the longitudinal direction is formed by a section parallel to the scribe lines or grooves, thereby forming two edge portions, each with open end, the pivot around the scribe lines in the inner region of the thus formed edge and there clamped and glued together are,

d) and wherein one end face of the edge element is formed by a pivoted edge portion and the other end face of the edge element by a non-pivoted edge portion. A portion of such an edge element is shown in Figure 1 with additional, inserted and bonded therein profile parts.

Advantageously, a container insbesonde ^¬ re one. Transport box or other parts such as Rahmentei ^¬ le or walls with cross braces, such as shelves or similar items to be made from as few standard parts. c) separated in the longitudinal direction is formed by a section parallel to the scribe lines or Rillungsli ^¬ lines, which form two edge portions, each with an open end, the pivot around the scribe lines in the In ^¬ nenbereich the thus formed edge and there are clamped and glued together,

Advantageously, the cross section of the starting material can be formed by the meter, as in a standard square tube produced by a square with rounded corners. The resulting corresponding by Mehrfachwicklung outer edges in such a square tube are molded edges of very high dimensional stability. This form of strength is advantageously exploited constructively in the inventive formation of the edge element, because a shaped edge of the square tube is also used as the outer edge of the edge element and the three remaining (former) outer edges of the square tube high resistance to force on the edge element in a plane perpendicular to the outer edge oppose and thus ensure high dimensional stability of the edge element.

Scoring lines or scoring lines are advantageously used in order to deform the cross-sectional shape of the divided quadrangular tube in a precisely defined manner. When a first line is placed so that the resulting associated first open end edge portion rests on the inner side of the adjacent quadrangle side upon complete inward pivoting, and a second line is placed such that the resulting associated second edge portion with the open end at full inward pivoting rests on the same inside of the adjacent square side and jammed with the first edge portion with an open end, and optionally the stuck in the jamming parts are still glued together, then there is a particularly high dimensional stability ,

If in square cross section of the square tube as. Starting material the scribe lines or scoring lines the opposite sides in the respective reciprocal ratio m: n and n: m share, where m + n each gives the length of a quadrilateral, then results in a particularly easy to produce, expedient solution for the edge element, because the outer edges are parallel to the inner edges.

Example:

Length (over all) of an outer edge: m + n = 11 cm, m = 8 cm, n = 3cm. (see also schematically Figure 1). If the edge element has one or more openings in its end faces (length n = 3 cm) through which a side part for the component to be created can be inserted and locked, the structural basis is created for an easily implementable attachment of a component transversely to the longitudinal direction of the edge element.

In addition, when a connection profile inserted in the edge member in alignment with the openings and secured therein (e.g., by bonding) and a predetermined profile shape is provided, and

a included by the side part strut with one or more matching the profile shape of end portions and having a locking groove is provided, which are arranged such that the end portions and the matching profile ^¬ form come together when the connection between edge element and side panel into abutment, and thereby a Randab ^{¬ section of} the openings passes into the locking groove, whereby a clamping fit is generated between the side part and edge element, then results in a particularly stable, and easy to produce connection of the side part with the edge ^¬ element, which is also very easy to solve the Tei ^¬ le for the purpose of (return) transport to disassemble space ^¬ saving.

This connection is referred to as "snug fit connection" and can be with or without bonding and with or without Ras ^¬ tion, and can also between other components than the Edge element are produced, for example, between longitudinal and transverse struts of side parts, as will be described below.

Preferred for the profile shape is a wedge shape with matching V-shape, see Figure 1, because it is easy to produce, self-centered and has a large adhesive surface. But also arcuate pass lines can be realized instead of said wedge / V. In a particularly preferred manner can now be a very stable, easy to produce and easily removable transport box with a plurality of such edge elements and with several, provided between the edge elements, and attachable to these side panels, as well as a plurality of side panels and / or on one or more edge elements attachable bottom part can be made. However, the bottom part does not necessarily have to be firmly connected to the side parts or the edge elements depending on the manner of use.

According to a second aspect of the present invention, regardless of the above-mentioned edge elements, a transport box is disclosed, comprising a bottom part, a plurality of edge parts which can be placed on the bottom part, and other than those described above and as in the prior art

Technically known built up edge elements based on four or poly tubes with internal reinforcing tubes, but with a snug fit connection between the components of the side parts and between the side parts and the edge elements as mentioned above.

If the bottom part and / or a cover part comprises two parallel longitudinal struts which are connected to each other by meh ^¬ rere cross struts such that the crossbars with their end portions through openings in the interior of the longitudinal struts pluggable and together are available with a Passitzverbindung and optionally glued, then a uniform, simple production for the components and their compounds is achieved. When, for example, for producing a connection between a first part, such as longitudinal struts of a side part, and a second part attached perpendicular thereto, such as lateral struts or an edge element, the connection profile fastened on or in the first part essentially comprises the connection profile fastened by gluing a U-shaped profile whose legs are bent with a predetermined portion along predetermined scribe lines or Ril- lines in the interior of the U and the base portion of the U rest and thus form a directed into the interior of the U V-shape, see as far as schematic

Figure 1, and when the end portions of the second parts, such as cross braces, are formed tapered to fit the V-shape, so that a fit results, so a simple to produce connection is created, which is very stable mechanically.

It is advantageous if the longitudinal struts have a ^rectangular cross-section and, by virtue of a connection profile glued therein, are capable of connection to one another and mechanically reinforced to the other.

It is advantageous if the transverse struts have a ^rectangular cross-section and have reinforcing tubes inside, which are dimensioned in this way _. are that predominant parts of the inner surface of the cross member are in abutment with the Ver ^¬ strengthening tubes.

It is advantageous if a cover part is provided with a structure analogous to the bottom part as described above, since then a uniform construction is maintained. It may be advantageous if the side parts including the edge elements are provided without gluing to the bottom part. This is especially true for an application in which the bottom part is placed on a euro pallet, then the body of side panels and edge elements is placed, loaded the top open box from above with the goods to be transported and possibly the lid part is placed. Thus, the transport box thus formed with stretch or shrink film can be coated and even strapped without the goods are damaged, because the edges around protect very well and are stable.

If a comb strip for parallel, constant spacing arrangement and fixing of plate-shaped goods in correspondingly the plate thickness provided comb grooves is attached to at least one transverse strut of the bottom part and two opposite side parts, then the transport box is ideal for transporting heavy plate-shaped goods or components, such as glass panes, solar panels or window elements, flat screens, etc ..

If the transport box according to the invention is lined with an inner lining of corrugated cardboard or other low-cost recycled material, so the Trans ^¬ portbox is also suitable for the transport of heavy bulk material.

Description of exemplary embodiments

In the figures, the same reference numerals designate the same or functionally identical components.

FIG. 1 schematically shows a sectional view of a section of an edge element 10 according to the invention with connecting profiles 42 inserted and glued on both sides in a perspective view.

Figure 2A shows schematically a cross-section of the edge element 10 according to the invention during the manufacturing process after it has been split from a wound square tube through a cut 30 and after two score lines 28A, 28B have been diametrically offset on opposite sides of the square tube. In FIG. 2B, the pivoted parts are completely folded in and form the inner sides or the end faces of the edge element.

The starting material for the production of an inventive edge element according to this embodiment is a square tube, which is more or less arbitrary by the meter Length of multiple layers of recycled paper is prepared by being wrapped around a molded article defining the cross-sectional shape according to the prior art. This tube has a wall thickness of, for example, 3 mm and is well known in the art in terms of structure, material and manufacturing process. The square tube as the starting piece therefore has four Formkanteh, which are determined by the shape of the above-mentioned shaped body of their position and their radius of curvature ago.

As can also be seen from FIG. 2, the square tube according to the invention has as a starting material a square cross-section, for example with an edge length outside of 11 cm.

Preferred method of manufacturing the edge element

10:

1) In a first operation of a producible on a machine in a single working edge element scoring lines 28 A and 28 B are on two opposite sides of a square tube coming from the outside generated by the square tube at two in the prior art be ^¬ known and fixed mounted scribe tools at exactly predetermined, diametrically opposite points of the cross section is set and moved parallel to its outer edges to produce a corresponding scribe line in the longitudinal direction in the pipe. Alternatively, a scoring tool is also suitable for producing two grooves instead of two scorings.

2) Then, in a second operation, preferably on the same machine, a longitudinal cut is made at a precisely predetermined location also parallel to the outer edges on the quadrangle side which lies between the sides with the score lines. This section is designated by reference ^numeral 30 in FIG. As a result, the square tube of the Length after split. As a cutting tool is a corresponding fixed knife or a saw with a relatively thin sheet.

Process 1) and 2) can also be reversed in order.

3) In order to arrive at the position shown in FIG. 1 starting from a square tube pretreated as described above via the position shown in FIG. 2, in a third process the two edge sections 32 and 34, which have an open end at the cutting surface, are interspersed the score lines 28 are each pivoted inward.

This works because the material has been similarly weakened during the scribing process.

The positioning of the two diametrically opposite score lines 28 A and 28 B results in that the standing after pivoting end face 20 of the edge element is the same size as the short leg 32 A of the first edge portion with an open end, because then runs in the right Angle to the portion 32A extending edge portion 32B parallel to the scribe line adjacent square side 38th

In the embodiment shown, for example, the square tube has an outer length of .11 cm each. Cutting line 30 is at a distance of 3 cm from the left upper corner of the illustration. Implied by this measure results for the length of the corresponding marked edge portion 34 A with an open end a length of 8 cm.

Thus, this second edge portion with an open end 34 A can also be pivoted and a parallel edge guide to the outer edges of the square tube he ^¬ gives, therefore, the scribe line 28 B must also besit ^¬ zen seen a distance of 3 cm from the upper right corner ,

If now the edge portions 34 A and 34 B are pivoted so far until the cut surface 30 rests on the inside ^¬ side of the square side 38, so can in a wide Ren operation, the second pivotable edge portion 32 B and 32 A are also pivoted, and indeed so far, until it rests with its cutting surface 30 also on the inner surface of the quadrilateral 38. The support lines are lines which are indicated by the points 36 and 37 in FIG.

4) The two cutting surfaces 30 can be glued to the side 38 and the two in clamping contact edge portions 32, 34 with an open end can be glued together.

This basic shape of the edge element according to the invention and the simple manner of its production cause excellent static loadability even with relatively thin wall thickness, in particular against transverse forces acting in the drawing of Figure 1, for example from above or from the left or right to the edge element, such as the Case is when transport boxes, which seen from above have a rectangular cross-section with inventively designed outer edges, for the purpose of

Transport in trucks with tight straps are strapped and strapped, or if they are filled with heavy bulk material, which generates a corresponding pressure on the support surface to the outside.

Thus, the edge element 10 shown may serve in a particularly preferred manner as a connecting element between two struts, which are to be connected in each transverse direction zuein ^¬ other over the edge element, openings 40 are provided in the end faces 20 and 22 of the Kantenele ^¬ Mentes, through the through a suitably shaped end portion of said struts can be inserted. Thus, these transverse braces are accurately fixable now in its direction and can be fixed to the edge element 10 comparable inhibited, preferably, a Verbin ^¬ extension profile part 42 is in alignment with the openings 40 on the respective, the openings 40 opposite side inserted and fixed there preferably by gluing to the abutting edge end portions with open end 32, 34. The profile part of the connecting profile 42 is preferably made of a square tube, a U-shaped tube or a correspondingly shaped flat material.

This profiled part 42 can likewise be produced by the meter and wound, and is severed centrally by a cut, so that the two V-legs result when the profiled part 42 is processed on corresponding grooving lines 43 such that the free V-thighs retreat be pivoted inside on the base side of the profile part and there are jammed together by the fact that the entire profile part 42 is inserted into the narrow cross-section of the limited by the end face interior of the edge element and glued therein.

The gluing is done either only selectively or nationwide by spraying the surfaces coming into contact with each other.

FIG. 3 shows, in a perspective and partially exposed view, an edge element 10 according to the invention with openings 40 for insertion and engagement of transverse or longitudinal struts 44 into the aforementioned connection profile 42.

Such a strut 44 is shown with its pointed end ^¬ section 46 in contact with the V-shaped legs of the connecting profile 42. For this purpose, it was previously inserted through an opening in the edge element 10. A free opening without inserted cross member is shown by reference numeral 40 on the other side of the edge ^¬ elements.

Thus, with the edge element shown, struts can be used which, when properly seated, are positioned and fixed at exactly right angles to each other are. The tapered end portions 46 of the struts 44 may still be glued to the edge member 10 as needed, for example in the region of the tapered portions 46 or adjacent to them, at those locations where they are in contact with the edge member 10.

As can also be seen from FIG. 3, openings for inserting the transverse struts can be formed practically at any desired point along the longitudinal extent of the edge element, ie several such openings can also be arranged one above the other, because in a preferred embodiment the connecting profile 42 extends continuously over the entire length of the Edge element is inserted. FIG. 4 shows a transverse or a longitudinal strut 44 during its production from a square tube with three space-filling inner reinforcing shaped parts which are here designed as square tubes 80. Other cross sections may also be suitable here.

The structure of a strut 44 shown in Figure 4 is in principle suitable for both longitudinal and for Querstre ^¬ ben which are arranged between the inventive edge members. In a preferred embodiment of such a strut 44, the interior has a Rechte.ckförmigen

Cross-section, which is filled practically full-surface by square tubes. In Figure 4, three adjacent square tubes are shown. The inner four ^¬ square tubes 80 have a wall thickness of 2 mm. The outer material, which forms the outer skin of the strut, also has a wall thickness of 2 mm. The strut is formed by a ^¬ zelne square tubes, each of which is known from the prior art methods has been wound from the above erwähn ^¬ th recyclable material.

To the reinforcing tubes 80 in a simple manner in the

Inside the strut 44, the strut 44 can be separated longitudinally, as shown in Figure 4, then the inner reinforcing tubes 80 are inserted and then the separated legs are glued to the underlying reinforcing tubes again.

Exemplary dimensions of such a strut are: length: 40 to 200 cm, width 7 cm, height 3 cm, and for the inner reinforcing tubes 80 the same length, width about 2 cm, height about 3 cm. Depending on the length and the required compressive strength and bending stiffness, these dimensions can be varied if necessary together with the material composition. In principle, it can be realized in accordance with all necessary for transport purposes of goods measures specific to the respective product requirements.

FIG. 5 A shows a strut from FIG. 4 after the end sections 46 have been sharpened on both sides by a sawing or milling process in order to be designed to match the profile shape of the connection profile 42.

As can be seen in Figure 5A, the end portions 46 of the strut 44 are completely chamfered, including the outermost layers of material, by said sawing or cutting action, precisely at the angle which is present as a V-shape in the reinforcing profile 42. In order to realize a particularly good fit, this angle can be slightly larger than the corresponding angle of the connection profile 42. As an angle difference ranges between 1 degree and 4 degrees are recommended, depending on the compressibility of the material.

Furthermore, it can be seen in FIG. 5A that a latching groove 48 is provided at both end sections. Into this, a certain portion of the edge of the openings 40 shown can be inserted, which then becomes a

Clamping seat of the strut in the edge element according to the invention results. This clamping fit can be resolved by the strut is slightly raised to remove the latching groove 48 from the opening edge 40. Thus, a re-releasable, very stable and relatively accurately positionable. Clamp connection created. By gluing these compounds can also be made irreversible. The latching groove 48 is advantageously produced by sawing with a saw blade of suitable thickness. FIG. 5B shows an enlarged illustration of the end section 46 of the strut 44 from FIG. 5A with a clear illustration of a latching groove 48.

FIG. 6 shows diagrammatically and perspectively a transport box 2 according to the invention, which has an edge element 10 according to the invention on the four vertically depicted edges, with two respectively shorter and two respectively longer side parts 60 ^' and bottom part 70 as well as multiply glued comb strips 82 ,

The exemplary embodiment of a transport box 2 according to the invention shown in FIG. 6 contains a bottom part 70, which will be discussed further below, a body consisting of four side parts 60 and four edge elements 10 arranged therebetween of corresponding struts 76, 78, which are constructed as the above-described struts 44 which connect between the respective edge elements 10, as well as so-called comb strips 82 which are attached to certain of these struts and intended to fix certain goods to be transported with the transport box shown.

In detail, two short side parts 60A and 60C and two longer side parts 60B and 60D are provided. The shorter side portions 60A and 60C have three transverse struts 78 interconnected by vertically extending connecting struts 62. This connection can take place in ^¬ example by gluing. Above all, it is half expedient so that a short side part can be easily connected to an edge element 10, because then all three transverse struts 78 inserted simultaneously into the openings provided in the edge elements 10 openings 40 and can be locked therein by means of the previously described Einrastnuten 48.

Preferably, the longer side parts 60B and 60D are prefabricated from the factory and already connected to two edge elements 10 in order to enable a quick assembly of the transport box 2 on the one hand and on the other hand a space-saving transport of their components. The connection to the edge elements 10 required for the mentioned longer side parts is preferably analogous to the connection of the short side parts. However, it can be reinforced in a preferred manner even by a bond that occurs factory. If this should not take place, the above-described clamping fit is enough to create a powerful, stable and robust transport box herstel ^¬ len to.

To make the detent mechanically even more stable, it may be advantageous to reinforce the opening edge, which engages with the Einrastnut 48, by a U-shaped clip. This clip can for example be made of synthetic material ^¬ and should be removable for recycling in the simplest possible way back from the edge of the purpose of material purity, after being placed on them. In the illustrated embodiment also includes each of the longer side portions 60B and 60D of three superimposed angeord ^¬ designated longitudinal struts 76th

The comb strips 82 are in the bottom part 70 and on the two opposite short side parts 70, and there in a special way on the middle strut 78, the one as described above reinforced construction, attached, preferably by gluing it. There are furrows provided, see also Figure 11 reference numeral 84 and its description, which are designed so that certain high-quality and transported goods can be inserted there and remain in the grooves 84 in a clamping fit. With suitable groove depth and furrow width is thus a very reliable and material-friendly transport of plate-shaped goods possible.

A bottom part 70 is provided, on which the above-described body of side parts 60 and edge elements 10 is placed. Preferably, there is no adhesive bond between the body and bottom part. This can of course be produced if necessary. The bottom part 70 contains two stable longitudinal struts 72A and 72B and four equally spaced parallel arranged Quererstre ^¬ ben 74. Conveniently, the two longitudinal struts 72A and 72B for the purpose of a stable and easy to make connection with the cross struts 74 also the openings 40 and the connection profiles 42, as have been described above in connection with the execution and con ^¬ structuring the edge elements 10. In this way, a bottom part 70 can be produced in a relatively simple and fast manner.

The. Connections between longitudinal struts and cross struts can also be glued.

Not shown in Figure 6 is a cover part. However, it should be noted at this point that such a cover part can also advantageously be part of the transport box 2. In principle, it may be the same structure as the base part 70, which has been previously ^¬ be enrolled. All of the said struts can be interconnected with each other in the manner described using the connection profile 42. The transport box 2 shown in Figure 6 is at a

Wall thickness of the edge elements of 3 mm loadable up to 2 tons and can be stacked.

FIG. 7 shows, in cross-section and in a diagrammatic view, a strut without inserted reinforcement tubes, which can be used in particular as an outer edge strut in the bottom part and / or cover part, with an inserted connection profile 42 which is used for connection to a sharpened strut according to FIGS. 5 A and 5 B should serve.

Advantageously, the struts of the bottom portion 70 on a projecting edge portion 79, which has the function of preventing the mounted on a bottom portion 70 of the body can slip off again. The body is placed in the interior of the rectangle, as it is generated by all sides upstanding edge portions 79.

As is further apparent from FIG. 7, such a strut contains, as already described above, a connecting profile 42, which, viewed in cross-section, is inserted into one of its corners and glued there, whereby it has exactly the internal dimensions of the strut as external dimensions is made analogous to the struts 44, preferably a square tube, a U-shaped tube or a correspondingly shaped sheet.

FIG. 8A shows schematically and in cross section a strut 74, 78 which can be used as a longitudinal or transverse strut, in each case with three inserted reinforcing tubes 80, in order to achieve a high load capacity. The cardboard tubes 74, 76, 78 shown in FIG. 6 are preferably shaped such that the inner tubes 80 can actually serve as mechanical reinforcement. This requires either a high own carrying capacity of these reinforcing tubes 80 or requires that the reinforcing tubes 80 fill the interior of the cross section of the strut 74, 78 as space-filling as possible. Everything else applies here, which has already been described above in connection with the strut 44 and FIGS. 5A and 5B and FIG.

Figure 8 B shows a strut, which can be used advantageously as edge strut 88 in the bottom part o- and also in the cover part of a transport box according to the invention because of their special, drawn upwardly extending open edge portion 79.

FIG. 8C shows a perspective view of a strut which can be transversely coupled to the strut, as shown in FIG. 8B, with the strut shown in FIG. 8B being sharpened, as shown in FIG

Connecting profile 42 used as shown in FIG 8C and, where appropriate, ^¬ can be glued therein.

The strut shown in Figure 8C has exemplified openings 40 which are provided side by side in one of the narrow end faces of the strut in order to connect it in the manner described three other struts can.

From the above description, it should be clear that when two struts together or a strut with an edge element in the transverse direction to each other mitein ^¬ are to be connected, the one strut or the edge element to the cross section of the other strut pas ^¬ send opening and a should contain aligned with the opening connection profile 42, and the other strut pas ^¬ send should be pointed to the connection profile 42 to to achieve a good fit and a high connection stiffness.

Conversely, a connection is of course also possible, namely that the strut contains the female connecting element and the edge element contains the corresponding male connecting element.

In addition, of course, other matching shapes than the described V-shape and the corresponding sharpened shape can be selected for the fit.

Figure 9 shows a longer section of a

Edge strut 88 of the bottom part 70, in particular a longitudinal edge strut 79 according to Figure 8 C with internal connection profile part 42, with two recesses 86 at each edge and two openings 40 for respective insertion of cross struts according to Figures 5 A, 5 B and 8 B.

FIG. 10 shows a cover part 90 or bottom part 70 with its production, in which two transverse struts 74 already connect the two outer longitudinal struts 72A and 72B and the third transverse strut has come in from the outside (bottom right in the drawing) and has been pushed in the direction of the arrow a bond. FIG. 11A shows, in a schematic and perspective view, a comb strip 82 for insertion into the bottom part 70 of a transport box 2 according to the invention or for insertion on two opposite struts 78 of opposite side parts 60A, 60C for the parallel spacing and fixing of plate-shaped goods in accordance with the plate thickness provided ridges 84th

The furrows 84 have a width which is precisely adapted to the requirements of the product to be transported in the transport box. Has this in ^¬ play, a thickness of 10 mm, the Kammfurche- should have approximately a gap width of 9.5 mm. This results in an advantageous clamping seat between these parts. The ridges 84 are preferably made by sawing or milling operations.

In the interior of the comb strip 82, tubes made of the same wound material can now advantageously also be present. In a particularly advantageous manner, pipes with a round cross-section can also be used, as shown in FIG. 11, if it is desired that the product to be transported should have only a relatively small contact with the substrate.

According to Figure IIB goods can be transported in a press fit, which have a slightly tapered cross-section towards the edge.

The material to the. Preparation of the elements described is typically recycled paper, which is wrapped in webs on certain shaping moldings per wound until a certain wall thickness is reached. This material is well known in the art consists approximately of 70 to 85 weight percent of paper, from 5 to 10 weight percent starch or starchy biopolymers, a certain proportion of residual water and possibly also from other plastic materials, in particular ^¬ thermoplastic materials, in particular polyethylene, polypropylene or oriented polypropylene.

Although the present invention has been described above with reference to a preferred embodiment, it is not limited thereto but in many ways. modifiable.

Instead of scribe lines, so-called scoring lines can usually also be produced with so-called scoring wheels or other suitable tools from the prior art. to bend or pivot certain pipe sections in a predetermined manner.

The transverse strut 44 as illustrated in Figures 4, 5A, 5B and described above may also be constructed in other ways than shown. For example, you can choose from a square tube instead

• flat material (for example 3mm thick) with appropriate grooving, or

Be prepared from a cross-sectionally U-shaped material in which then the legs are designed after appropriate grooving also as shown in Figure 4.

Or the outer tube of a strut may also be formed integrally with the inner "filling", the supporting filling being folded according to the contour of the interior to be formed, after being grooved or scored on corresponding lines, this being exemplified in Figures 12A and 12B 1, wherein the numbering of the edges indicates that the imaged part has been produced in one piece by grooving and bending sequentially according to the numbers at the respective edge lines of the numbered edges FIG. 12B shows that the outer shell of the surfaces 18 to 35 was dispensed with in the part shown in FIG. 12A.

Is shown in the interior of the strut such as in Figure 8A, other than the Verstärkungsform- shown parts can be realized with square cross-section, Example ^¬, a zigzag line, triangular, round, oval, pointed oval in whole or half, or other fractions of , used in ^¬ example as a semicircular cross section, pointed arch cross-section ^¬, etc..

The same applies to the production of the profile parts 42nd The described edge elements can also have a different cross-sectional contour than the L-shaped contour shown in FIG. To choose accordingly different is the cross-sectional shape of the starting product. Therefore, if necessary, in cross-section 5-angular, hexagonal or polygonal, regular or irregular shapes can be offered depending on the use and set load capacity.

It is also similar to the struts 44 flat material (eg 3mm thick) with appropriate grooving, or in cross-section U-shaped material in which then the ^¬ individual pages after appropriate grooving also as shown in Figure 1 can be designed. The described edge elements can in further

Be used for a variety of purposes, such as the manufacture of furniture or stable frameworks for furniture, for racks, shelves, frame members, and when used outdoors with appropriate impregnation.

Finally, the features of the subclaims can be combined substantially freely with one another and not by the order given in the claims, provided that they are independent of each other.
