Description

The subject of the invention is a shelf support made of a foldable, flat material having a shell rear wall and two shell side walls, the shell side walls being articulated to the shell rear wall via folding edges, the shell side walls each having at least one slot for receiving a tab of a shelf and the shelf support a shelf shell and has a reinforcement layer. The invention also relates to a multi-part blank for a shelf support and a display comprising a shelf support and at least one shelf.

Many goods are placed on mobile goods shelves (displays) at the point of sale (Point-of-Sale, PoS) or presentation location (Point-of-Presentation, PoP), which make it possible to present goods separately or to create additional sales areas. Conventional displays usually have several shelves in which the goods are placed. A large number of shelves can effectively create additional shelf space. The shelves must be stable enough to carry the goods, at the same time they must allow an appealing presentation of the goods. The presentation of goods is particularly well done with open shelves, where the goods can not only be seen from the front of the shelf, but also partially from the shelf sides.

Depending on the design, some shelf displays are also difficult to set up because they consist of a large number of components. There is therefore always a risk that the shelf display will be damaged during assembly and cannot be used optimally. The manufacture of many components is also more complex and therefore more expensive.

An open shelf construction is from the DE 103 13 159 A1 known, which describes a shelf made of a foldable, flat material such as cardboard. The shelf has a shelf support and several shelves, the shelves each having tabs that are inserted into slots in the shelf support. The special construction of the shelves creates a shelf that is easy to set up and has a high level of optical transparency. The disadvantage is that the shelf support consists of a large number of components and is therefore complex to manufacture.

The DE 10 2016 222 956 A1 describes a cardboard shelf with a shelf support and at least one shelf held by the shelf support. The shelf support has two side walls, each with an outer layer and an inner layer. The construction of the shelves described is special. A shelf has a base and a reinforcement layer on the base that at least largely covers the base. The base area and the reinforcement layer are formed in one piece from a common blank made of cardboard and are connected to one another via at least one crease line on a front or rear edge of the base area and the reinforcement layer. The shelves are only hung in the inner layer of the shelf support, so that the shelf support is less suitable for heavier goods.

U.S. 5,392,902 A discloses a shelf display which is suitable for the presentation of products in the form of individual packages, as well as in the form of cardboard boxes containing a number of individual packages. The shelf display has a vertically disposed corrugated cardboard back panel, a pair of opposing vertically disposed corrugated cardboard side panels, and a plurality of vertically spaced corrugated cardboard shelves placed between the opposing side panels. The shelf display has closed side walls that extend over the entire depth of the shelves so that the goods can only be seen and removed from the front of the real display.

The object of the invention is therefore to provide a shelf support that overcomes the above disadvantages and, in particular, is inexpensive to manufacture, is easy to set up and consists of a few individual components.

The object is achieved according to the invention by a shelf support according to patent claim 1.

Further embodiments are the subject matter of the subclaims or are described below.

The shelf support according to the invention has a shell rear wall made of a foldable, flat material, such as cardboard or corrugated cardboard, and two shell side walls made of a foldable, flat material, such as cardboard or corrugated cardboard. The shell side walls are hinged to the shell rear wall via folded edges. Before the first construction of the shelf support, all the walls of the shelf support are parallel to the same plane and the rear wall and side walls of the jacket form a surface. After setting up, the shell side walls are each at right angles to the shell rear wall, so that the shelf support has a U-shaped cross section. The shelf support is also known as the display jacket. The casing side walls optionally each have at least one slot for receiving a tab of a shelf. The slot for inserting a tab of the shelf preferably has a vertical course or a course inclined at an angle from the vertical. The shelf support according to the invention has a shelf jacket and an associated reinforcement layer. The shelf shell and the reinforcement layer together form the shell rear wall and the two shell side walls. The shelf jacket and the reinforcement layer are flatly connected to one another, preferably glued to one another. The shelf jacket has a rear wall field and two side walls articulated to it via folding edges. The reinforcement layer has at least one reinforcement rear wall and two reinforcement side walls. Before the first assembly, the reinforcement side walls are each hinged to the reinforcement rear wall via a tear-fold edge. This tear-fold edge is preferably designed as an interrupted cutting line or as a perforation. The interrupted tear-fold edge has at least one area in which the tear-fold edge is designed uncut. These uncut areas of the tear-folded edge act as retaining straps or webs, since they connect the reinforcement side walls to the reinforcement rear wall before erecting and hold them to the reinforcement rear wall. The uncut areas of the tear and fold edge are preferably shorter than the cut areas of the tear and fold edge.

The term below refers to the end of the shelf support facing the floor on which it stands in the erected state. The term above refers to the end of the shelf support facing the sky or the ceiling in the erected state.

The shelf support according to the invention consists of two parts - a shelf jacket and a reinforcement layer. Both parts are flatly connected to one another in the area of the rear wall of the jacket and in the area of the two side walls of the jacket, in that they are preferably glued to one another, preferably lying flat before being set up. The planar connection can be implemented over the entire area, punctually or over part of the area. The shell side walls are folded forward during assembly, i.e. when erecting.

Since the reinforcement layer is flatly connected to the shelf shell, the individual elements of the reinforcement layer cannot move in their position relative to the fields of the shelf shell. During assembly, the shelf jacket and the reinforcement layer are folded along the folds. The creasing on the folding edge compresses the material on one side, which is why it can be folded, even when using corrugated cardboard, although corrugated cardboard is basically rigid. In the reinforcement layer, which is located on the outside of the rear wall of the jacket, there is a tension in the material in the area of the folded edges that cannot be resolved by shifting the reinforcement layer and the shelf jacket relative to one another. For this purpose, the tear-folded edge has interrupted areas in which it is cut, as a result of which a material weakening is achieved. If the reinforcement side walls of the fully glued shelf support are folded forward, the uncut areas of the tear-folded edge, i.e. the retaining straps, tear open and the shelf support according to the invention can be easily assembled. A cracking noise is generated, which signals to the user that the shelf support is now fully assembled. The cut areas of the folding edge tear and are no longer present after the shelf support has been set up. In the erected state, the parts of the reinforcement layer, i.e. reinforcement rear wall and reinforcement side wall, are no longer connected to one another. The reinforcement side walls automatically separate from the reinforcement rear wall during assembly; additional cutting or processing during assembly is not necessary.

The small number of parts of the shelf support - two parts, namely shelf jacket and reinforcement layer - is therefore only possible because a tear-fold edge is present. Due to the weakening of the material along the tear and fold edge, it tears in the uncut areas during construction.

The shelf support according to the invention consists of a multi-part blank. The shelf jacket preferably consists of a one-part or multi-part blank. The reinforcement layer preferably also consists of a one-piece or multi-part blank, preferably of a one-piece blank. In a preferred embodiment, the shelf support according to the invention consists of two blanks, one blank for the shelf jacket and one blank for the reinforcement layer. In a further embodiment, the shelf support according to the invention consists of four blanks, namely three blanks for the shelf jacket and one blank for the reinforcement layer. In this variant, the shelf jacket has a cut for the rear panel field and side walls and two cuts for the cladding of the jacket feet.

The invention also relates to a multi-part blank for a shelf support consisting of a one-part or multi-part blank for a reinforcement layer, preferably a one-part blank, and a one-part or multi-part blank for a shelf jacket.

In a preferred embodiment, the blank according to the invention for the reinforcement layer is in one piece and has a reinforcement rear wall, preferably a rectangular reinforcement rear wall, to which reinforcement side walls are hinged on both longitudinal sides, the reinforcement side walls being connected in an articulated manner via a tear and fold edge. The tear-fold edge between Reinforcement rear wall and reinforcement side wall are designed to a large extent as a cut line and in smaller areas uncut as retaining straps or webs, ie it is an interrupted cut line or perforation.

The special construction of the blank according to the invention allows inexpensive production and a simple construction of the shelf support. After the corrugated cardboard sheets or corrugated cardboard sheets have been produced, the blanks are punched out, whereby in the preferred embodiment only one punching tool is required for the one-piece cut of the shelf shell and the one-piece cut of the reinforcement layer or two punching tools, one each for the one-piece cut of the shelf shell and the one-piece cut of the reinforcement layer . The small number of parts allows easy gluing. The glued shelf support can be delivered flat and set up at the place of use without additional gluing, cuts or assembly of several individual parts. The suspension for the shelves is already integrated and allows the shelves to be attached easily.

In one embodiment, the reinforcement side walls each consist of two or three folding elements, namely a first folding element, a second folding element and possibly an inner foot element. In this case, a first folding element is hinged to the reinforcement rear wall, which is designed as a perforated support, for example. The first folding element has a rectangular strip in the upper area. When designed as a perforated support, it has holes in the upper area that are used for hanging shelves. In the lower area the first folding element widens, i.e. the width increases obliquely outwards towards the floor, whereby a jacket foot is formed. A second folding element, which is preferably filled over the entire surface, is articulated to the longitudinal side of the first folding element via a further folding edge. The second folding element has a rectangular outline in the upper area, the width of the second folding element being less than or equal to the width of the upper area of the first folding element. The second folding element has any end to the bottom, e.g. a straight vertical edge or a polygonal or triangular point. The folding edge between the first folding element and the second folding element may have elongated recesses which also serve to reduce material and facilitate folding along the folding edge. Alternatively, the blank is designed without a second folding element.

In one embodiment, an inner foot element is articulated to the lower edge of the first folding element via a further folding edge. The inner foot element forms the reinforcement of the mantle foot and has, for example, a pentagon shape with two adjacent right angles, the corners being arranged at right angles on the folded edge. The inner foot element is preferably partially congruent with the foot area of the first folding element. The inner foot element serves to stabilize the mantle foot.

The blank according to the invention for the shelf jacket is made in one piece in a first variant. It then has a rear wall field and two side walls hinged to the longitudinal edges of the rear wall field. The side walls of the shelf jacket are preferably composed of several fields. A first wall field is linked to the rear wall field via a folded edge. The first wall field has the shape of a rectangle in the upper area. In the rectangular area, the first wall panel inclined slots that serve to accommodate the tabs of the shelves. In the lower area, the first wall panel widens obliquely outwards, ie it increases in width in the direction of the floor, as a result of which the casing foot is formed. If the shelf jacket is multi-layered, the first wall panel has, in a variant, a further folded edge on the second longitudinal side. A connecting strip is linked to the first wall panel via this folding edge. The connecting strip preferably has a width which is slightly greater than the wall thickness of the reinforcement layer. The course of the connecting strip follows the shape of the outer edge of the first wall panel. As far as the first wall field has a rectangular plan, the connecting strip runs parallel to the rear wall field. In the lower area, in which the first wall field on the foot part widens obliquely outwards, the connecting strip runs obliquely outwards. The connecting strip is hinged to the second wall panel via a further folded edge. The second wall field preferably has the shape of a rectangle in the upper area. In the lower area on the foot part, it preferably has essentially the shape of a trapezoid that widens outwards. An outer foot panel is linked to the lower edge of the first wall panel or the second wall panel by means of connecting straps. The outer foot field preferably has a rectangular floor plan with a base that is widened outward at an angle. The connecting straps are arranged in the area of the widened base.

The blank according to the invention for the shelf jacket is designed in several parts in a second variant. The multi-part blank has a first blank for the rear wall field, first wall field and, if necessary, second wall field. Two further, mirrored cuts form the outer foot reinforcement. In this embodiment, too, a first wall field is linked to the rear wall field via a folded edge. The first wall field has the shape of a rectangle in the upper area. In the rectangular area, the first wall panel has inclined slots that serve to accommodate the tabs of the shelves. In the lower area, the first wall field widens, possibly in a small area, increasingly obliquely outwards towards the floor. If the shelf jacket is multilayered, the first wall panel has a further folded edge on the second longitudinal side, via which a connecting strip is hinged to the first wall panel. The connecting strip has a width that is slightly greater than the wall thickness of the reinforcement layer. The connecting strip runs parallel to the long edge of the rear panel field. The connecting strip is hinged to the second wall panel via a further folded edge. The second wall field has the shape of a rectangle. The second variant of the blank has two blanks for reinforcing the outer foot. These blanks each have a first reinforcing surface with a floor plan in the form of a pentagon with three adjacent right angles. A second reinforcing surface is connected via a strip-shaped connecting band.

The shelf support according to the invention is preferably unfolded from the blank according to the invention.

In order to advertise the goods, the side walls and / or the rear wall of the shelf support may be printed or the display is provided with an additional top sign for advertising.

In one embodiment of the shelf support according to the invention, the side walls of the shelf shell are two-ply, i.e. double-walled, and the reinforcement side walls of the reinforcement layer are each arranged between the two wall panels of the side wall of the shelf shell. In the area of the shell side wall, the shelf shell is then folded around the reinforcement layer so that the reinforcement side walls of the reinforcement layer form a core which is positioned in the cavity formed by the wall panels of the shelf shell. In this embodiment, the shelf shell is designed in two layers in the area of the shell side walls, a first wall field of the shelf shell and a second wall field of the shelf shell being connected to one another via a connecting strip. The connecting strip is linked to the first wall panel via a folded edge and to the second wall panel via a folded edge. As a result of this construction, a reinforcement side wall of the reinforcement layer is surrounded on three sides by the shelf jacket. In this embodiment, each of the side walls consists of three or four layers of material, the shelf support having a multi-layer shelf jacket and a single or multi-layer reinforcement layer enclosed therein.

In a preferred embodiment, the shelf support has feet in the lower region of the shell side walls, which are formed by widening the shell side wall in the lower region. The feet are part of the shell side wall and do not form a separate component. The feet are preferably formed by the reinforcement layer and are encased by the shelf jacket. They are turned inside out by a lower area of the shelf jacket, which may be glued to the shelf support with an adhesive flap. The feet increase the stability of the shelf support and this has improved stability.

The shelf support according to the invention consists at least partially, preferably completely, of corrugated cardboard. Optionally, the corrugated cardboard is lacquered on one or both sides at least in places.

If the shelf support according to the invention consists of corrugated cardboard, the corrugated cardboard preferably has two or more corrugated layers in places. The corrugated cardboard preferably has wall thicknesses between 1 mm and 20 mm, preferably between 2 mm and 12 mm. In the case of the shelf support according to the invention, the corrugated cardboard preferably has a vertical wave course when the shelf support is set up.

The folding edges in the shelf support according to the invention are preferably designed as creased lines. This applies to both the folded edges between the shell rear wall and the shell side walls, as well as the folded edges in the blanks for the shelf shell and the reinforcement layer. Only the tear-folded edge between the reinforcement rear wall and reinforcement side wall is designed as a creased line interrupted by cutting lines.

The invention also relates to a display consisting of a shelf support according to the invention, as described above, and at least one shelf, each shelf having at least two tabs which are arranged in the slots of the shelf support.

The display, also known as a sales stand or goods display, is used to present goods at the presentation location or point of sale. A display consists of at least one shelf support and one or more shelves. The shelf support carries the shelves and offers additional space that can be labeled and printed, e.g. with product information or advertising.

The display according to the invention preferably has a height between 60 cm and 3 m, a width between 30 cm and 1.5 m and / or a depth between 20 cm and 80 cm. The size of the floor plan of the shelf support according to the invention preferably corresponds to a ¼ CHEP pallet, also called a quarter pallet.

The shelf in the display according to the invention preferably has at least one tab articulated to the shelf via a folding edge for insertion into the slot in the shelf support, a base area, and wall parts connected to the base area via folding edges. The tab connected to the shelf is preferably arranged on one of the wall parts or an extension of one of the wall parts. When the shelf is set up, the slot in the shelf support into which the shelf is inserted is above a level defined by the base area of the shelf. Since the shelf support according to the invention is designed in several layers, the slot is at a point at which the shelf support has at least two layers, so that the tab lies between two layers of the shelf support in the inserted state.

The base of the shelf is preferably horizontal or inclined. In one embodiment, the shelf is shaped as a pocket. The base area of the shelf preferably has two layers, which are possibly connected to one another via a folded edge.

The shelf support according to the invention is preferably unfolded from the blank according to the invention. According to the invention, the method for producing the shelf support from the blank according to the invention comprises at least the following steps:

• • Provision of a blank for a shelf jacket,
• • Provision of a blank for a reinforcement layer, the blank preferably being in one piece,
• • Placing the cut of the reinforcement layer on the cut of the shelf shell so that the reinforcement back wall lies on the back wall field and the reinforcement side wall on the wall field of the shelf shell,
• • if necessary, alignment of the reinforcement layer and shelf shell to one another using marking holes,
• • planar connection of the reinforcement layer to the shelf jacket, preferably gluing, the connection preferably being made at points, over part of the surface or over the entire surface.

In one embodiment of the method, a one-piece blank is first provided for the reinforcement layer. At the same time, a blank is provided for the shelf jacket. In the next step, the blank for the reinforcement layer is placed on the blank of the shelf jacket. The reinforcement rear wall comes to lie on the rear wall field and the reinforcement side wall comes to lie on the wall field of the shelf jacket. The reinforcement layer is flatly connected to the shelf jacket, preferably glued. The connection is made selectively, partially or over the entire surface. The wall panels are glued to the reinforcement side walls.

The blanks optionally have marking holes that serve as adhesive markings. The holes of the reinforcement layer and the shelf shell are superimposed during the connection and thus allow the reinforcement layer and the shelf shell to be aligned with one another.

In a further embodiment of the method, a one-piece blank is first provided for the reinforcement layer. The blank has first and second folding elements for the reinforcement side walls. The second folding elements of the reinforcement layer are folded along the folding edges and folded over in the direction of the first folding element and glued there. After gluing, the second folding element completely covers the first folding element from one side. In addition, if necessary, the inner foot elements are folded along the foot folding edge and turned over so that they come to lie on the foot area of the first folding element, where they are also glued.

In the next step, a one-piece blank is provided for the shelf shell, and the pre-glued blank for the reinforcement layer is placed on the blank of the shelf shell. The reinforcement back wall comes to lie on the back wall field and the reinforcement side wall comes to lie on the first wall field of the shelf shell. If a blank is used for the shelf jacket in which the side walls consist of several wall panels, the next step is to fold the wall panels of the shelf jacket inwards to the rear wall panel so that they cover the reinforcement side wall. The wall panels are glued to the reinforcement side walls.

To form the jacket feet, the cut of the shelf jacket optionally has outer foot fields and additional fields in the foot area. This lower area of the second wall field and the outer foot field are turned over. At the sloping jacket feet, the outer foot panels are folded over along the connecting straps, folded onto the reinforcement layer and also glued to the reinforcement layer. Likewise, the lower area of the second wall panel is folded along the two folding edges on both sides of the connecting strip and glued to the reinforcement layer.

The cuttings for the shelf jacket and reinforcement layer optionally have marking holes that serve as adhesive markings. The holes of The reinforcement layer and shelf jacket lie one on top of the other during gluing and thus allow the reinforcement layer and shelf jacket to be aligned with one another.

1 shows a shelf support according to the invention 1 after standing up. The shelf support 1 has a coat back wall 2 and two opposite shell side walls 3 . The shell side walls 3a and 3b are perpendicular to the shell rear wall 2 and are about folded edges 4th and 5 with the rear wall of the coat 2 connected. Each of the side walls 3a, 3b consists of three corrugated cardboard layers, with the shelf support 1 a multi-layer shelf jacket 10 and a reinforcement layer included therein 20th Has. It can be seen that the shelf jacket 10 in the area of the shell side walls 3 is designed in two layers, with a second wall panel 12th and a first wall panel 11 via a connecting strip 13th are connected. The connecting strip 13th is in each case via folding edges on the first wall field 11 and the second wall panel 12th hinged.

On the inside 6th the shell sidewall 3 are slots 7th attached, which are used to attach shelves (not shown). The shelves have tabs that fit into the slots 7th in the shell side wall 3 can be pushed. In the exemplary embodiment shown, the shelf support 1 in the lower area of the shell side walls 3 Feet 8th which are formed by widening the side wall. The feet 8th are part of the shell side wall 3 . The feet are made of the reinforcement layer 20th and are formed by a lower area of the shelf shell 10 turned inside out, which is glued on with an adhesive flap.

2 shows a section of the shelf support 1 out 1 from the reinforcement back wall. The rear wall of the coat 2 is designed in two layers, while the shell side wall 3 is executed in three layers. The shelf support consists of a shelf jacket 10 and a reinforcement layer 20th . In the area of the shell side wall 3 is the shelf coat 10 around the reinforcement layer 20th folded around so that the side wall area of the reinforcement layer forms a core that is passed through the side walls of the shelf shell 10 formed cavity is positioned.

Reinforcement layer 20th and shelf coat 10 are flatly connected to one another while lying flat, ie lying flat by gluing them together while lying flat. The jacket sidewalls 3 are folded forward during assembly. There are special straps for this 9 in the reinforcement layer 20th introduced that the reinforcement back wall 21 the reinforcement layer with the reinforcement side walls 22nd the reinforcement layer 20th connect.

3 shows the shell side wall 3 of the glued shelf support 1 out 2 Folded forward, the straps 9 are cracked and no longer recognizable. The second wall field 12th and first wall panel 11 enclose the reinforcement sidewall 22nd the reinforcement layer and this is arranged as a reinforcement layer in the shelf jacket. The rear wall of the coat 2 is designed with two layers, with the reinforcing back wall 21 the reinforcement layer forms the outwardly facing side of the shell rear wall and the rear wall field 14th of the shelf jacket forms the inside facing the shelves.

The first wall field widens in the lower area 11 increasing diagonally outwards towards the ground. The first wall field 11 has, as with the first variant of the blank, a further folding edge on the second long side 16 on over which a connecting strip 13th to the first wall field 11 is hinged. The connecting strip 13th has a width that is slightly greater than the wall thickness of the reinforcement layer. The connecting strip 13th runs parallel to the long edge of the back panel field 14th . The connecting strip 13th is via another folding edge 17th to the second wall field 12th hinged. The second wall field 12th has the shape of a rectangle. There is an adhesive tab on the top edge of the first wall field and on the top edge of the second wall field 31 hinged. The cut for the outer foot reinforcement 32 has a first reinforcement surface 33 with a floor plan in the form of a pentagon with three adjacent right angles. Via a strip-shaped connecting band 34 is a second reinforcement surface 35 connected. It essentially has the shape of a trapezoid that widens outwards.

In 6a is a one-piece cut for the reinforcement layer 20th shown. The second folding elements 27a and 27b are along the cutting line 26th and the connectors 29 folded and folded over in the direction of the first folding elements and glued there. In 6b the second folding element is already glued to the first folding element and covers it completely. Accordingly, the first folding element can no longer be seen. The inner foot elements are along the foot fold edge 30th folded and stand straight up. They are turned over so that they come to rest on the foot area of the first folding element, where they are also glued.

6c shows the next step in unfolding the shelf support according to the invention. First, the cut for the shelf jacket 10 provided, shown here with a first variant of the shelf jacket according to 5b and the pre-glued blank for the reinforcement layer 20th according to 6b placed on it. The reinforcement back wall 21 comes on the back panel 14th to lie and the reinforcement sidewalls 22nd come on the first wall fields 11 of the shelf jacket. In 6d can be seen as the reinforcement layer 20th in the shelf coat 10 is placed. The second wall panels 12th of the shelf jacket are folded inwards so that they are the reinforcement sidewalls 22nd cover and are glued to the reinforcement sidewalls. To form the jacket feet, the lower area of the second wall field and the outer foot field are turned over. The outer foot fields are on the sloping coat feet 18th unfolded along the connecting straps 19, folded onto the reinforcement layer and also glued to the reinforcement layer. Likewise, the lower area of the second wall panel is folded along the two folding edges on both sides of the connecting strip and folded onto the reinforcement layer. 6e shows the completed shelf support in the flat state. The complete gluing in the reinforcement layer and between the reinforcement layer and the shelf jacket has been carried out.

There are small round marking holes in all figures 36 recognizable. The holes serve as adhesive markings.
