Description

Field of the invention

The present invention relates to a socket which is particularly suitable for a sales exhibitor or a sales shelf. It also relates to a method for producing such a base.

Background of the invention

The Auslegeschrift 27 56 960 (corrugated cardboard factory Schumacher GmbH) discloses a transport container, which can also be used as a display socket. This container or base is reinforced by two arranged at the bottom of hollow bar. The hollow beams are each formed from a plurality of mutually hinged material sections, usually from Pappabschnitten. Of course, the hollow beams give a display base a high stability. However, their shape appears complex and will therefore probably only be made at the factory.

The Utility Model G 89 01 600 (CDE Commerce Display) discloses another sales display with a pedestal. This is specially designed as a pallet display. In this case, the sales display is arranged on a pedestal, which in turn can be placed on a pallet. The base has two side walls. However, these are not straight, but angular so that they are buckled to the interior of the base. As a result, the base, given a load from above, added stability. Furthermore, webs are provided in the interior of the base, which extend between the front wall and rear wall of the base. These bars are recognizable to spend individually in the desired position between the front wall and rear wall.

The externally recognizable buckling of the side walls can be felt as an aesthetic disadvantage of this construction.

Another pedestal is from the document JP H4-4604 Y known.

The present invention desires to provide a socket in a simple economical manner. It should be easy to transport, light and stable. Furthermore, it should be easy to produce.

These advantages are achieved by the socket according to claim 1 and by the method according to claim 5.

The present invention is therefore a pedestal for a sales shelf. However, the use of a shelf is to be understood only in terms of aptitude and also typical or preferred use. The base is also suitable for other objects, for example, it could also be a bookshelf. Typically, the pedestal is used for object in a showroom, perhaps a display rack or a merchandise rack or table instead of a shelf. The base includes an internal compartment and an outer shell.

Here, the Innengefache essentially serves the support and stabilization of the base. This internal compartment comprises a first reinforcing web and a second reinforcing web. However, the internal compartment may also comprise further reinforcing webs, for example a third or fourth reinforcing web. It is often useful to arrange the reinforcing webs symmetrical to each other. Each reinforcing web may comprise a plurality of web portions. These web sections are expediently hinged to each other, so firmly connected to each other, but mutually movable. The reinforcing web can be carried out in one piece or in several pieces. The reinforcing webs can be made of wood or plastic, expedient are usually paper and cardboard, in particular Corrugated cardboard. The web portions may generally be interconnected directly or indirectly. For direct connection, it is expedient if two web sections are made in one piece and are connected by a weakening line. Such a line of weakness may be a scoring or perforation. For indirect connection could serve a separate component, such as a joint. Alternatively, for indirect connection also other sections between two web sections are used, for example, those which are articulated on two sides over lines of weakness.

The outer shell should have a first sidewall, an adjacent second sidewall, a third sidewall opposite the first sidewall, and a fourth sidewall opposite the third sidewall. Conveniently, these side walls are arranged at right angles to each other, so that the outer shell describes a total cuboid shape. The first side wall is conceivable as a front wall, the third side wall as a rear wall, the second side wall as a right side wall and the fourth side wall as a left side wall. All or some of the side walls may also be broken or have recesses. The side walls can also be largely broken so that they are designed as a peripheral frame with, for example, two or four webs.

For the purposes of the invention, the first web section should be connected to the second side wall via a pressure-resistant connection. Likewise, the fourth web portion should be connected via a pressure-resistant connection with the fourth side wall. Such a pressure-resistant connection may be a plug or abutment connection. In such variants, the compound can forward pressure forces, with tensile forces, the compound dissolves again. But a pressure-resistant connection can also be additionally tensile. This is usually the case with fixed connections. Such solid compounds can be in various produce mechanically, but in particular by gluing. It is expedient to provide an adhesive flap. Often it is expedient to provide this adhesive tab on the web portion to be joined of the connecting web. The tab may be bent relative to the web portion, so that it offers a large usable adhesive surface for connection to the shell.

The second and the third web section are to be connected via a tensile connection with the first or with the third side wall. It may therefore be, for example, a connection to the front wall or the rear wall of the base. A zugbelastbare connection could be produced for example via a cord. However, other tensile connections can also be pressure-resistant. Again comes for the connection a mechanical connection, in particular in the form of a bond in question. In this case, an additional component may be provided, which offers an adhesive surface.

This can be a glue flap, but it can also be another component. In particular, it is advisable to provide a connecting section between the second web section and the third web section. This connecting portion may connect the second land portion to the third land portion. For example, the three sections can be hinged to one another, that is to say be formed in one piece from a blank. The connecting portion may then be positioned to offer a large adhesive surface for bonding to the outer shell. The connecting lines between the connecting portion and the web portions may be movable to establish a mobility between the second web portion and the third web portion and the outer shell, respectively.

By punching it is also possible to bend out of parts of the first and / or the second web portion an anchor tab. These Anchor tab may be for bonding in a plane with the connecting portion. As a result, the available adhesive surface is larger and it can be selected more favorable adhesive dots for connecting the connecting portion with the outer shell.

It may also be expedient to provide corresponding anchor straps for further elements of the base. In particular, adhesive tabs can be provided with anchor tabs. This can be done by the anchor tabs are formed by punching portions of the adhesive tabs.

It is also advantageous if the socket described can be converted from a useful configuration into a transport configuration. In the payload configuration, the socket occupies a large volume, for example, the cuboid shape described. In the transport configuration, the parts of the outer shell can be stacked flat. Thus, the invention also generally relates to a socket which can be transferred from a transport configuration into a payload configuration.

Advantageously, for non-destructive purposes, non-destructive transfer from the payload configuration to the transport configuration is possible. To facilitate this transfer, it is expedient to make the reinforcing webs in a certain way. It has proven to be advantageous if the adhesive tabs with which a web portion of a reinforcing web is attached to the outer shell, opposite to the adjacent to the web portion next web portion are bent. This results in that the kinks are not overloaded, and the transfer of the reinforcing web is facilitated in a flat configuration, which is favorable for transport.

In this sense, it is particularly advantageous to design a pedestal, wherein between the first adhesive flap and the first web portion a first crease line is provided and in which between the first web portion and the second web portion a second crease line is provided and the second web portion in a first direction out of the plane defined by the first web portion and points out the first adhesive flap in a second direction from the plane defined by the first web portion and the second direction of the first direction is substantially opposite.

It is also advantageous in this sense to offer a base in which a fourth bend line is provided between the second adhesive flap and the fourth bridge section and in which a third bend line is provided between the fourth bridge section and the third bridge section and the third bridge section is provided in a third Direction points out of the plane defined by the fourth web portion out and the second adhesive flap in a fourth direction from the plane defined by the fourth web portion out and the fourth direction of the third direction is substantially opposite.

It is advantageous if, in the base, the first web section and the second web section form a right angle with one another in the useful configuration. In this way, the web portions can provide high stability in different directions with different loading of the socket. The web sections also stabilize each other. Therefore, it is also advantageous if, alternatively or additionally, the third web section and the fourth web section form a right angle with one another in the useful configuration.

A socket according to the present invention may already have sufficient stability if only one reinforcing web is used. It is advantageous to use two reinforcing webs in the rule. There these two webs alone can ensure a sufficient stability of the base for common purposes, it is particularly advantageous if the two reinforcing webs are arranged mirror images of each other. This ensures a clear structure of the base, which makes, for example, the transfer of the base of the transport position into a use position intuitive and easier. It is particularly useful if in the outer shell of the base, namely advantageously provided in the side walls fold lines. The base can therefore have a first fold line in the second side wall and a second fold line opposite in the fourth side wall. These two opposing fold lines define a plane. Also, by the two reinforcing webs, when they are arranged in mirror image to each other, defines a plane, namely the mirror plane of this mirror symmetry. It is advantageous if the plane defined by the fold lines coincides with this mirror plane. This results in a completely symmetrical base, which is designed to be stable for a variety of loads and can be easily converted from a Nutzkonfiguration in a transport configuration and vice versa. For this purpose, it is sufficient to pull the fold lines apart within the described level. This movement then causes the second and fourth sidewalls of the pedestal to be folded upon themselves and the first and third sidewalls to be moved towards each other.

It is expedient to provide the side walls at the top and at the bottom with Umlegelaschen. This Umlegelaschen can facilitate in the upper level, so to speak in the table level, the placement, for example, a shelf on the pedestal. In the lower level, ie the floor level of the base, they ensure that the base has a better footing on a surface. Such a substrate can be a floor. More often, however, the base is placed on a pallet, for example on a quarter pallet. This facilitates the transport of the base with and without attached shelf. In addition to the Umlegelaschen may be provided in particular at the lower ends of the side walls of the base and insertion tabs. Such in the middle of the side walls provided tabs can be inserted into receiving grooves of typical quarter pallets.

The present invention relates not only to a socket, but also to a method for its production. The advantages of the socket construction as such are complemented by advantages resulting from the ease of manufacture of the socket. Also, advantages provided by the method of manufacturing the socket are enhanced and enhanced by the advantages of the finished socket as an article.

The invention relates to a method for producing a socket, which comprises the following steps:

• Providing a blank for the outer casing comprising sections for the first side wall, for the second side wall, for the third side wall and for the fourth side wall, the section for the second side wall being a first fold line and the section for the fourth side wall being a second one Fold line and the portion for the third side wall between the portion for the second side wall and the portion for the fourth side wall is arranged;
• Providing a second blank having at least portions for a first reinforcing web, the first reinforcing web having a first end portion, a second end portion, and at least one middle portion;
• Applying connecting means to the first and / or second blank;
• Producing a pressure-resistant connection between the first end portion of the first reinforcing web and the second side wall using the connecting means, wherein the compound in the region of the third side wall oriented side of the first fold line is located;
• Producing a pressure-loadable connection between the second end portion of the first reinforcing web and the fourth side wall using the connecting means, the connection being in the region of the side of the second fold line oriented towards the third side wall;
• Making a loadable connection between the central portion of the first reinforcing web and the first or third sidewall using the connecting means;
• Turning over the portion for the first side wall so that the first side wall substantially covers the third side wall;
• Do not turn over the part of the second sidewall covered by the blank for the first reinforcing web along the first fold line;
• Do not fold it along the second fold line by the portion of the fourth side wall covered by the blank for the first reinforcing web;
• Connecting the second side wall and the fourth side wall to the first side wall.

These steps are preferably carried out in the order of their enumeration. Often it is also possible to swap the order of individual steps. For example, it is possible for the connecting means to be applied to the first or second blank (or both) before it is made available for carrying out the further method steps.

In most cases, the first blank is larger than the second blank and in particular it is then advantageous to apply the bonding agents to the first blank. As an alternative to applying connecting means to the first blank, it is possible to apply these connecting means to the second blank. The first blank, ie the blank for the outer shell, comprises sections for the four side walls. In the description of the elements of the blank, the following description does not always strictly distinguish between an element as part of the blank and an element as part of the finished base for greater readability. The blank is preferably in one piece. Alternatively, it could also be prepared by assembling several parts.

The second blank is also preferably in one piece. The first and the second blank may be made of the same or may be made of different materials. In general, the materials mentioned above for the base are advantageous; corrugated cardboard is again particularly advantageous. In particular, it is then also possible, for example, by creasing, to provide in corrugated cardboard easily certain fold lines.

The connecting means can in turn be varied. For example, there are two-part connection means in question, for example, mechanical connection means with a male and a female element. Then, corresponding connection means are to be provided on the blank for the outer shell and on the first blank and on the second blank. For other fasteners, it is sufficient if they are provided only on a blank. This is especially true for adhesive joints. In the context of the present invention, it is often advantageous to provide flat, for example strip-shaped adhesive orders on a blank. It has proved to be advantageous, all Connecting means, ie, for example, all adhesive surfaces only on a blank, usually provided on the first blank.

Also in the context of the method, it is advantageous if the blank for the reinforcing web has four or five sections. The middle section corresponds to the second web section and the third web section or the second web section, a section for a connecting section and the third web section.

As regards the production of the pressure-resistant and tensile-loadable connections in the context of the method, it is advantageous that a part to be joined or an adhesive flap hinged thereto is connected by contact and preferably pressing with an adhesive application. Among the great advantages of the method described it is important that with the help of relatively less simple steps, an outer shell and a Innengefache can be made of two blanks and thereby even without additional steps even the Innengefache and the outer shell can be interconnected.

An attractive variant of the method results when a base is produced with two reinforcing webs. In this case, an unchanged first blank can be used. In this case, the second blank may advantageously comprise both sections for a first reinforcing web and sections for a second reinforcing web. In this case, the second blank can be in one piece. The reinforcing webs can each again comprise a plurality of web sections. Consequently, the central portion of the reinforcing ribs may comprise a plurality of separate sections, for example, again a section for a second web section, a section for a third web section and also a section for a connecting section. In the context of this method, the second blank should have a fold line by which the first reinforcing web and the second reinforcing web are separated from each other and along which the reinforcing webs can be folded towards each other. Conveniently, this third fold line extends at least substantially perpendicular to the first fold line and / or second fold line, which are provided in the outer shell.

• Verbinden der zweiten Seitenwand (14) und der vierten Seitenwand (18) mit der ersten Seitenwand (12)

Consequently, the invention also relates to a method for producing a base with second reinforcing webs, which comprises, preferably in this order, the following steps:

• Providing a blank for the outer shell comprising sections for the first side wall (12), the second side wall (14), the third side wall (16) and the fourth side wall (18), the section for the second side wall (16) a first fold line (50) and the fourth sidewall section (18) comprises a second fold line (52) and the third sidewall section (16) between the second sidewall section (12) and the second sidewall section (12) the fourth side wall (18) is arranged;
• Providing a second blank having at least portions for a first reinforcing web (20) and for a second reinforcing web (40), the first reinforcing web (20) having a first end portion, a second end portion and at least a middle portion, and wherein the second reinforcing web (10) 40) has a first end portion, a second end portion and at least one central portion
• Applying connecting means to the first and / or second blank;
• Folding the second blank before or after establishing a pressure-loadable connection between the first end portion of the first reinforcing web and the second side wall and before or after establishing a pressure-resistant connection between the second end portion of the first reinforcing web and the fourth Side wall and before or after establishing a load-bearing connection between the central portion of the first reinforcing web and third side wall, wherein the second blank is folded along a third fold line (54), which preferably at least to the first fold line (50) is substantially perpendicular
• Do not fold over the portion of the second sidewall (14) blanked by the blank for the first stile (14) along the first fold line (50) to make a pressure-loadable connection between the first end portion of the second stile and the second sidewall
• Do not fold over the portion of the fourth sidewall (18) blanked by the blank for the first stile (18) along the second fold line (52) to form a compressive connection between the second end portion of the second stile and the fourth sidewall (18).
• Connecting the second side wall (14) and the fourth side wall (18) to the first side wall (12)

It is expedient if the second blank is placed on prepared splices of the first blank so that in the process a connection of sections of the first reinforcing web to the first blank takes place. In particular, a pressure-resistant connection between the first end portion of the first reinforcing web and the second side wall and a pressure-resistant connection between the second end portion of the first reinforcing web and the fourth side wall and also a zugbelastbare connection between the central portion of the first reinforcing web and the third side wall is thus made become. By making these connections, the second blank is relative to the first one Fixed blank so that folding over of parts of the second blank along the third fold line is facilitated. But it is also possible to make this folding before making the enumerated compounds or simultaneously with the preparation of enumerated compounds. For these situations, in which the folding takes place in about the same mental, but also the same actual, second as the making of the connections, it is also referred to herein as folding or flipping "under construction" of a connection.

The further method steps relating to the outer shell, correspond to the method for producing a base with a reinforcing web. Interestingly, it is possible to produce the required connections between the second reinforcing web and the outer shell at substantially unchanged process steps. By providing an adhesive bond on the second side wall outside the first fold line, the folding over of the outer part of the second side wall results in not only providing the outer shell in a suitable form, but also in providing a pressure-resistant connection between the first End portion of the second reinforcing web and the second side wall is made. Therefore, it is a flipping of a part of the second side wall to make a pressure-resistant connection. In the context of the invention, it is advantageous that both essentially take place in one work step, exact simultaneity is not required. In a corresponding manner, by compressing the outer part of the fourth side wall along the second fold line, a pressure-resistant connection between the second end portion of the second reinforcing web and the fourth side wall can be produced.

It is expedient if the blank is designed for a substantially cuboidal base. In particular, it is expedient if the blank has a portion for the third side wall which is substantially rectangular and comprises two longitudinal edges and two transverse edges, wherein on one of the longitudinal edges a portion for the first side wall is hinged and wherein at the transverse edges respectively sections for the second side wall and the third Side wall are hinged. Such a blank thus has a substantially T-shape. It is also expedient if the blank has on the adjacent section for the second side wall, so to speak on the outside of this section, an adhesive tab which is used to connect the second side wall to the first side wall. The adhesive flap is thus, so to speak, at the free end of the section for the second side wall. Similarly, it is also advantageous to provide an adhesive tab on the fourth sidewall portion. With this adhesive flap or these adhesive tabs, a good connection between the second side wall and possibly also the fourth side wall and the first side wall can be produced.

If in the blank a direct connection between the section for the first side wall and the section for the third side wall is provided, for example in the T-shaped blank described above, then it makes sense between the section for the first side wall and the section for the third side wall to provide a line of weakness. This line of weakness allows for a simple folding of the sections towards each other. On the other hand, it is possible, in another, usually late or final step of the process, to separate the two sections along the line of weakness.

In the context of the present method, it is also expedient to provide a strip-shaped adhesive surface at least parallel to the first fold line, which serves as a connecting means for producing a pressure-resistant connection with at least one reinforcing web. It is also useful, such a strip-shaped adhesive surface also parallel to second fold line provide. If a base with two reinforcing webs is produced in the context of the method, it is advantageous to provide a strip-shaped adhesive surface on each side of each fold line. In this very simple manner, the required pressure-resistant connections between the second and the fourth side surface and the reinforcing webs can be produced.

It is also advantageous to provide such a strip-shaped adhesive surface on the third side wall. This adhesive surface can in turn produce a tensile connection with a reinforcing web as a connecting means in the sense of the method claim 10. It is advantageous in the context of the method, when the adhesive surface is placed so that it produces a zugbelastbare connection with a possibly existing connection portion of the reinforcing web.

It is advantageous if a strip-shaped adhesive surface is provided in a corresponding manner on the first side wall. With this then a zugbelastbare connection can be made with the other reinforcing web. The strip-shaped adhesive surfaces on the first and on the third wall expediently extend in the direction of the side edges of the base, based on the finished base, ie from top to bottom.

The method is particularly simple to carry out if the first blank is in one piece. A further simplification results, even if the second blank is in one piece.

Other features, but also advantages of the invention will become apparent from the following drawings and the accompanying description. In the figures and in the accompanying descriptions, features of the invention are described in combination. However, these features may also be included in other combinations of an article of the invention. Every revealed feature is therefore also to be regarded as disclosed in technically meaningful combinations with other features. In some drawings, such details and reference numerals have been omitted for simplicity, which are not material to the understanding of the invention due to the drawing. In the drawings show:

Fig. 1 shows a base according to the invention in a perspective view. In the base 10, the various side walls and the Innengefache can be seen. The base 10 has a first side wall 12, adjacent thereto a second side wall 14, adjacent to a third side wall 16 and adjacent thereto a fourth side wall 18. The first side wall 12 is conceivable as a front wall and the opposite third side wall 16 as a rear wall. The wall 14 then forms the right side wall and the wall 18 forms the left side wall. As Innengefache a first reinforcing web 20 and opposite him a second reinforcing web 40 is provided for the base 10. The two reinforcing webs are designed substantially symmetrical to each other and could be mirrored on a plane extending in the direction through the center of the base to each other. Hereinafter, only the elements of the first reinforcing web 20 will be described in detail for the sake of simplicity.

This has a first web portion 22, is hinged to this, a second web portion 24. The base 10 further includes a third web portion 26 and hinged thereto a fourth web portion 28. The second web portion 24 and the third web portion 26 are connected by a connecting portion 30th connected. This one is for the two articulated adjacent web sections. Via the connecting portion 30, a connection, namely a tensile connection to the third side wall 16 is made. About the first adhesive tab 32, the first web portion 22 is further connected to the fourth side wall 18. Opposite the fourth web portion 28 is connected via the second adhesive tab 34 with the first side wall 14. The adhesive tabs 32 and 34 produce a pressure-resistant connection. This pressure-resistant connection can be made by the mere mechanical arrangement of the adhesive tabs. We suggest her name, but the tabs are additionally glued to the adjacent side walls.

The connecting portion 30 is extended by a first anchor tab 36 and by a second anchor tab 38, which are punched out centrally from portions of the second web portion 24 and the third web portion 26. Thus, the anchor tabs are hinged to the connecting portion. The anchor tabs allow a larger area and more stable connection of the first connecting web 20 with the outer shell and concretely with the third side wall 16. Adhesive surfaces between the connecting portion 30 and the third side wall 16 and advantageous additional bonding surfaces between the side wall and the two anchor tabs can be easily a produce tensile load connection.

In the payload configuration of the socket, adjacent elements of the first reinforcing web 20 assume a substantially rectangular orientation to one another. To make this possible, various crease lines are provided. Between the first adhesive tab 32 and the first web portion 22, a first crease line 42 is provided. Between the first web portion 22 and the second web portion 24, a second crease line 44 is provided. Between the second web portion 24 and the connecting portion and between the connecting portion and the third web portion 26 crease lines are also provided, which are not designated for simplicity, however. Between the third Web portion 26 and the fourth web portion 28, a third crease line 46 is provided and between the fourth web portion 28 and the second adhesive flap 34, a fourth crease line 48 is provided. It is advantageous that the buckling direction along the fold lines 42 and 44 and also along the fold lines 46 and 48 is oriented opposite.

In the context of the present invention, the reinforcing webs can also have other shapes than in Fig. 1 displayed. While Fig. 1 shows a shape with few sections, which extend in the payload configuration substantially perpendicular to each other, are also round and polygonal courses of the reinforcing webs in the context of the present invention. Therefore, more bending line can be provided as in the embodiment of Fig. 1 , The corresponding fold lines generally run all parallel to each other.

Fig. 2 shows the socket according to the invention in the transfer from a transport configuration in the Nutzkonfiguration. In this configuration, the second side wall 14 and the fourth side wall 18 are kinked. A first fold line 50 is provided in the second side wall 14 for this purpose, and a second fold line 52 is provided in the fourth side wall 18 for this purpose. Such a fold line may comprise one or more lines of weakness. Advantageously, a fold line consists of two parallel weakening lines, as indicated. The two lines of weakness are separated by a small distance, which is expediently about two to five times the material thickness. In this way, a clean and tension-free folding of the side walls can be achieved. It can also be seen that even along the first to fourth crease lines instead of the right angles, more straight angles are present. In this case, the mentioned opposite orientation of the buckling along the fold lines 42 and 44 and 46 and 48 is advantageous.

It can also be seen from this view that pressure is essentially sufficient for two points in order to transfer the entire socket from this configuration into the useful configuration. It is sufficient to exert pressure on the outside of the area of the first fold line 50 and opposite to the area of the second fold line 52. Since pressure-resistant connections are provided adjacent to these fold lines, the pressure exerted on the outer shell can be transmitted to the inner compartment and in particular to the first and the second reinforcement web. Furthermore, pressure is transmitted via the outer walls. The transfer of the second side wall and the fourth side wall into a stretched configuration causes the distance between the first side wall 12 and the third side wall 16 to increase. This change of the outer shell also causes a change in the configuration of the reinforcing webs. By the pressure-resistant connection of the first reinforcing web 20 with the third side wall 16, the rear wall, and by the pressure-resistant connection of the second reinforcing web 40 with the first side wall 12, the front wall, the portions of the reinforcing webs are converted into the described Nutzkonfiguration in which the adjacent Sections are substantially perpendicular to each other.

Fig. 3 shows in perspective view from the same direction the converted into the transport configuration pedestal. It can be seen in this flat configuration, in particular the first side wall 12 and portions of the second and the fourth side wall. It can also be seen the opposite fold lines, namely the right fold line 50 and 50 left the second fold line 52. This configuration is obviously very space-saving. On the other hand, it is attractive that pressure has to be applied only at two very prominent points, namely the outer folding lines, in order to quickly and easily transfer the base from this transport configuration into the useful configuration. The process is so intuitive that it can be easily and quickly practiced by untrained personnel.

Fig. 4 shows in another perspective view of the base, which is located approximately in its Nutzkonfiguration. The view is essentially on the first side wall or front wall 12 and on the fourth side wall 18, which may also be referred to as the left side wall.

It can be seen the course of the second fold line 52, which consists of two parallel lines of weakness, the lines 52a and 52b These lines of weakness continue in the adjacent Umlegel ash, which is particularly easy to see for the upper Umlegelasche 54d. This makes it possible to precisely fold the complete side wall including the fold-over tabs when the fold-over lugs are erected.

The corresponding side walls continue at the top in Umlegelaschen. Starting from the first side wall 12, these are circumferentially the tabs 54a, 54b, 54c and 54d. When these tabs are folded inwardly, they are advantageously supported on the reinforcing webs. So they offer in the "table level" of the base a good support surface, for example, to set up a shelf. Also at the lower edges of the side walls Umlegelaschen are provided. Below the first side wall 12 while the fold-over tab 56a is visible and below the fourth side wall 18, the fold-over tab 56d visible. These tabs can also be turned inwards, and provide for better support of the base on the floor or other element arranged underneath. Such an element may be another socket, but will often be a pallet, for example a quarter pallet. With regard to the use of such pallets, are formed by punching out corresponding portions of the lower Umlegelaschen tabs. In the front wall 12 this is the tab 58a and in the left side wall 18 this is the tab 58d. Typical quarter pallets have receiving grooves that can accommodate these tabs. This results in a firmer connection between the base and arranged below pallet.

Fig. 5 shows a first step in the process for producing a socket according to the invention. In this step a first cut was made available. The first blank has sections for four side walls, namely the walls 12, 14, 16 and 18. The blank is designed substantially T-shaped. To the section for the third side wall 16, so for example the rear wall, left and right sections for the side walls, namely for the second side wall 14 and the fourth side wall 18 are hinged. The first side wall 12 is articulated on a longitudinal side of the third side wall 16.

Between the sections for the side walls are recognizable, but unspecified in this view, provided sections for the Umlegelaschen described. On the second side wall 14 and the fourth side wall 18, the first and the second fold line can be seen. Strip-shaped adhesive applications 60a, 60b, 60c and 60d are provided in parallel to these fold lines. These strip-shaped adhesive orders are referred to simplifying hereinafter as adhesive strips. Each further adhesive strip is provided centrally on the section for the first side wall and in a corresponding arrangement centrally on the section for the third side wall. These are the adhesive strips 60e and 60f.

Furthermore, adhesive strips 60g and 60h are provided on the portion for the first side wall 12. These adhesive strips serve later to connect this section with the sections for the second side wall 14 and for the fourth side wall 18. Therefore, these sections need not be directly connected to the side panels in the blank shown but can be connected to the extension tabs provided in the side walls become. This will be explained in more detail in the following figures. Well recognizable is a general Advantageous feature of the invention: All required glue lines can be applied in parallel in the same direction. In this respect, a very simple economic method can also be used to apply the adhesive jobs. This represents a significant further advantage of the method of manufacturing a socket as a whole.

In this view, a work table is also indicated. The method is particularly suitable for semi-manual processing of blanks. For example, two workers can act on the left and right of such a work table. The few work steps can be carried out well in a speedy semi-automated process. The automation may be limited in particular to the production of the blanks, the placement of lines of weakness, the application of fasteners and the transport of the blanks to the workplace.

Fig. 6 shows a further process step for the preparation of the base. In this step, a second blank is fed from the direction A3. In this case, it is expedient for the feed direction A3 to be opposite to the feed direction for the first blank, as is the case when the feed direction A2 has been selected or when this direction is perpendicular to the feed direction for the first blank, as is the case the direction A1 was chosen.

Fig. 7 shows a further process step. The second blank has sections from which a first reinforcing web 20 and a second reinforcing web 40 can be formed. In this view, these areas are indicated by reference numeral 20 and reference numeral 40. The sections intended for the first reinforcing web 20 lie closer to the first side wall 12 than the sections intended for the second reinforcing web 40.

As mentioned, the method is particularly well suited for a semi-automated design. Left and right of a work table, as well as in Fig. 5 implied, two workers can be active. These pull the supplied second blank to the appropriate position over the first blank and press it onto the first blank. This will produce the intended connections. This is described by the two hands symbolically indicated at corresponding points in this figure.

Fig. 8 shows a further step for producing a socket according to the invention. In this view, it can be seen that the sections for the first reinforcing web 20 are separated from the sections for the second reinforcing web 40 by a fold line 62. This fold line runs substantially perpendicular to the first fold line 50 (and thus also to the second fold line 52). In this view, the sections for the first reinforcing web are already connected to corresponding wall sections. It can be seen that the portion for the second adhesive tab 34 is already connected to a portion of the second side wall 14. For this purpose, the tab is positioned on the side of the first fold line 50 oriented toward the third side wall 16. The positioning of the first glue flap 32 is symmetrical. By the placement of the middle portion of the first reinforcing web and more particularly the connecting portion 30 of the first reinforcing web 20 on the in Fig. 5 recognizable adhesive strip 60e, a suitable zugbelastbare connection was created here. One recognizes in this Fig. 8 Also good that the fold lines, such as the fold line 50, is not covered by the second blank. Therefore, a later easy folding of the side wall along this fold line is well possible.

Again, symbolically hands are drawn. On each side can be pressed with one hand, the reinforcing web 20 on the blank below it. This fixes the two blanks on each other and ensures that a firm adhesive bond can be formed. With the second hand, a worker on each side can fold the second blank along the fold line 62. The two processes can therefore be conveniently performed simultaneously or in any order shortly after one another.

Fig. 9 shows the first blank with superimposed second blank, which has been folded in the manner described along the fold line 62. From this situation, it is convenient to fold the second sidewall portion and the fourth sidewall portion inward along the fold lines 50 and 52. This can be done from both sides essentially with one hand, for example as indicated. In this case, the outer adhesive tabs 64a and 64b drawn in this view can be gripped. Alternatively, the blank can of course also be touched at other locations of the sections for the side walls.

Fig. 10 shows a further step in the process. In this step, the opposite side walls 14 and 18 are folded inwardly along the fold lines 50 and 52. The adhesive tabs 64a and 64b now rest on the second reinforcing web 40. Starting from this configuration, it makes sense to take the section for the first side wall 12. This can be folded along the marked weakening line 66 in the direction of the third side wall 16 and thus at the same time also on the second reinforcing web out. An appropriate hand position for this is also indicated.

Fig. 11 shows a final step of the method in which the portion for the first side wall 12 has been folded onto the now no longer visible adhesive tabs 64a and 64b. The folding occurs along the weakening line 66. This facilitates the folding, but is now no longer necessary and is the transfer of the base in a Nutzkonfiguration in the way. Therefore For example, in a final step, the blank along the weakening line 66 can be separated, for example by a knife cut.

Overall, it can be seen how the base, which has an outer shell and a Innengefache, can be produced in a simple and very efficient manner. The few steps can be done well by one or two workers in a speedy semi-automated process. It is particularly advantageous that the elements are both produced and connected to each other. Regardless, the base itself is lightweight, easy to handle and stable.
