Abstract

The combination of back panel (3) and lateral parts (4) of the unit is created by folding the lateral parts (4) into four layers provided with a vertically positioned row of diagonal slots (11). The upper ends of two stands (6), accommodated with their lower ends in a base (12), can be inserted into the space between the layers from below. Each of the boards (2) is folded along predetermined lines in order to create elevated front and lateral borders (9) as well as flaps (10) at the rear of the lateral borders (9) for being inserted into the appropriate slots (11).

Description

The invention relates to a shelf made of a foldable, flat material such as cardboard or the like with a shelf support having a rear wall and at least one insertable shelf according to the preamble of the main claim or claim 9.

Generic shelves are used as goods display or for other purposes if low material and manufacturing costs, easy to set up or good disposal is desired. Such a shelf is known from the publication DE 198 60 305, in which the shelf support has two side walls in addition to the rear wall, between which shelves are suspended. The side walls are almost as deep as the shelves, so that side shelves create closed shelves. The design requires extremely large amounts of material, both in terms of area and related on wall thicknesses required for sufficient stability. It also creates an overall impression of a very closed shelf that lacks the transparency that is currently required for goods displays.

The invention is therefore based on the object of designing a generic shelf which, in comparison with a shelf according to the prior art, manages with smaller amounts of material while avoiding loss of stability, the shelves also being as accessible as possible from the side in order to achieve a transparent overall impression.

This object is achieved according to the invention by a shelf with the characterizing features of the main claim in conjunction with the features of the preamble of the main claim and by a shelf with the features of claim 9. Advantageous refinements and developments of the invention result from the features of the subclaims.

The invention makes it possible to use a shelf support with a significantly reduced depth compared to the prior art, and in particular to dispense with an almost complete lateral covering of the shelves by side walls. Compared to a tab which is articulated on a lateral edge of the base area and in particular at the level of the base area, a tab arranged on a wall part or an extension of a wall part of the shelf can be inserted above a level defined by the base area a point that is clearly offset in the direction of the rear wall. It is realistic to position the slot to accommodate the tab in one Area that lies above a last third of the shelf or the base of the shelf toward the rear wall, or is even offset beyond the base in the direction of the shelf support.

Any existing side walls of the shelf support can thus be considerably reduced in depth. This also makes completely different shapes for the shelf supports possible. The invention achieves a visually appealing and, in particular, very welcome for goods displays, transparent and less flat construction, which is accompanied by considerable material savings. Even with additionally reduced wall thicknesses, there is no loss of stability. In addition, such a shelf is extremely easy to set up, in particular, no gluing is necessary to attach the shelves.

In advantageous embodiments of the invention, the slot is a vertical distance above the level defined by the base of the shelf, which is between a fifth of a shelf depth and an entire shelf depth. The shelf depth is defined as the maximum horizontal extent of the base in a direction perpendicular to the rear wall. A good load-bearing capacity of the shelf is obtained with a ratio of the vertical distance to the shelf depth of between 1: 4 and 1: 1, a particularly good compromise between the load-bearing capacity of the shelf and transparency of its construction with values of this ratio of between 1: 3 and 2: 3 , Since the slot has a finite extent, an indication of its height or a height distance relates to its center.

In a preferred embodiment, the slot for receiving a tab is at a point at which the carrier has at least two layers, so that the tab lies between two layers when inserted. This prevents a kink from bending at the corresponding kink edge and slipping of the tab. A force caused by the shelf or by a load carried by the shelf can be transmitted to the edge of the slot on which the folding edge rests on the shelf support. Advantageously, the tab has a bend of 180 ° at the kink edge.

It is particularly advantageous if the shelf base has two tabs on each of two opposite side wall parts or extensions of side wall parts, preferably for hanging or inserting into one side wall of the shelf support. A particularly stable structure is obtained by loading the side walls in a direction that lies in a plane defined by a side wall.

The shelf support can form a substantially U-shaped cross-section with the two side walls, which are expediently connected to the rear wall by means of buckling edges and preferably form a substantially right angle therewith, as legs. In this case, it is very easy to double the side walls by turning each side wall upside down by another crease edge. The rear wall and the two-layer side walls can consist of one piece and be glued in places. In the case of a shelf support of the form described, the slots for hanging shelf shelves can face both facing and facing away from one another Be arranged sides of the side walls.

The shelf support can also be shaped so that it forms an all-round closed profile. An octagonal or hexagonal cross section is also conceivable, for example, so that the shelf support has the shape of a standing pencil, for example. In a particularly preferred embodiment, however, the shelf support has a rectangular horizontal cross section, in total, for example, a cuboid shape or a similar shape which tapers upwards through walls which are inclined towards one another. In these embodiments, the rear wall and the side walls of the shelf support are supplemented by a further wall that is parallel or almost parallel to the rear wall to form four outer walls. All four outer walls can be made from one piece and connected to one another via buckling edges, two of the outer walls being glued to one another in the region of a contact edge, for example by an adhesive flap. In the case of a closed shelf support of rectangular cross section, shelves can also be attached to two opposite outer walls, that is to say in particular both on the rear wall and on the outer wall parallel or almost parallel to the rear wall. A shelf support with a closed cross-section is particularly torsion and torsion resistant and leads to a shelf of great stability even when the shelf support has a relatively small depth.

The stability of the shelf can be increased further if the shelf support also has an inner profile with a shape that essentially corresponds to the shape of the shelf support, which is to be inserted between the outer walls such that the outer walls of the shelf support are supported by walls of the inner profile become. In such a construction, the walls of the inner profile can serve as a second layer, between which and a tab which is inserted through a slot in the outer wall and supports a shelf is to be clamped. The inner profile can also be made from one piece with walls connected to one another via buckled edges, possibly glued at a contact point between two edges, for example with the aid of one or more adhesive tabs.

A particular advantage of the invention described here lies in the fact that the shelf can be manufactured from inexpensive and environmentally friendly cardboard. A production from corrugated cardboard is particularly expedient, which can also be coated on one or two sides if a corresponding color is desired and an overly "sticky" impression is to be avoided. The use of corrugated cardboard brings with it an extremely high level of stability, and particularly good results are obtained if, depending on the component and the load, the corrugated cardboard is chosen with wall thicknesses of between 1 mm and 20 mm, preferably between 2 mm and 12 mm. To increase stability, heavily used components can also be made from corrugated cardboard with two or more corrugated layers.

In the case of a construction made of corrugated cardboard, it must be taken into account that corrugated cardboard is particularly resistant to buckling, primarily against kinking about an axis running transversely to the wave profile, the wave profile being defined as the direction of the profile of an individual wave valley. For a shelf that is as stable as possible for a given amount of material, it is particularly expedient if the corrugated cardboard, from which the rear wall, the side walls or further outer walls and, if appropriate, the inner profile or other components of the shelf support are made, has a vertical wave shape. For the flaps made of corrugated cardboard shelves, in turn, a corrugation that is as transverse as possible to the flap connecting the flap to the shelf is advantageous because corrugated cardboard also has a higher load capacity in the direction of the corrugation.

In the case of a shelf or components of the shelf made of corrugated cardboard, it is expedient to design the crease edges as creasing lines. If a fold of approximately 180 ° is provided on a fold edge to enclose a border of another surface, for example in the case of a fold edge that connects a flap to a shelf, it is particularly expedient to separate the fold edge by two approximately at a distance from one another to the wall thickness Creasing lines running parallel to each other.

In order to ensure that the shelf stands securely, feet are expediently provided, which are preferably also made from a flat material such as cardboard and which are advantageously inserted vertically into the rear wall and, when the shelf is erected, vertically aligned into an incision in a lower edge of the shelf support. The feet are preferably designed as widened legs, which can be inserted, for example, between two layers of a side wall of the shelf support. This further increases the stability of the shelf support. Such a foot can be designed so that it supports the shelf on one or both sides. The feet can be turned upside down from an advantageously also made of cardboard base part, which can have a shape similar to a shelf and both the safe stand of the shelf and its improves the safe standing of the shelf as well as its visual appearance.

In order to achieve an increased load-bearing capacity of the shelf, the shelf support can also be provided with one or more reinforcement walls, which can advantageously be inserted or clamped between two layers, and gluing to a wall or one layer of a wall of the shelf support is also possible. Such a reinforcement wall can also be designed as a slot reinforcement in the form of a double wall of the shelf support at a point where it has one or more slots for receiving tabs.

The base of the shelf can also be designed in two layers for reinforcement. A shelf can be made from a piece of corrugated cardboard, with the base area, side walls with flaps, possibly turned edges and possibly duplications of individual walls being connected to one another via folded edges. A more stable and resilient connection of the shelf with the shelf support is obtained if the shelf has one or more additional brackets, deflected by an edge of the base, which rests on the rear wall when the shelf is set up. Such a tab can either be inserted into an additional slot in the rear wall or glued to the rear wall. Even a shelf glued to the shelf support in this way would allow space-saving transport with a base lying against the rear wall; to set up, the shelf would simply have to be folded away from the rear wall in a particularly simple manner and inserted with the tabs of the wall parts of the shelf into the corresponding slots ,

In order to ensure the best possible power transmission, to prevent a tab from tearing along the buckling edge connecting the tab to the shelf, and to achieve the greatest possible stability overall with the least possible area and thickness of material, it is expedient if a slot is oriented in this way, that it is loaded by the hooked tab in a direction perpendicular to the slot if possible. Depending on whether and to what extent the rear wall of the shelf support can absorb weight forces caused by loading the shelf with the aid of additional brackets, the slot for receiving a bracket of a wall part of the shelf is advantageously to be arranged such that the bracket or the corresponding one When the shelf is set up, the edge holding the kink edge is either arranged vertically or inclined at an angle from the vertical that a vertical line removed from the center of the edge optimally cuts the base surface at a depth at which the shelf base is subjected to a heavy load during use (the tangent to it Angle then has the value of the quotient h / l if h is the mean vertical distance from the base and slot and l is the mean horizontal distance of the slot from a location where the base is primarily loaded, typically in the range between half and full shelf depth). A typical useful value for this angle is between 20 ° and 40 °. Incidentally, a slot for inserting a tab can also be widened and does not necessarily have to have opposing borders running strictly parallel.

In addition to shelves of typical shape for shelves with horizontal bases, different embodiments are also conceivable. In particular, the base areas of the shelves can be inclined, as may be desirable for goods or brochure displays, for example. The level of the base area in the sense of the main claim is defined in this case as the highest level taken up by the base area, in the case of a shelf that abuts the rear wall with the base area falling away from the rear wall, that is, as the height of an edge of the base area touching the rear wall. A shelf shaped as a pocket is also possible, such that the wall parts of the shelf have relatively large dimensions compared to the base area.

In order to compensate for the yielding of the shelf under load and to ensure that the shelf stands upright even when the shelf is loaded, the shelf support can be designed so that it or the rear wall when the shelf is unloaded by a small angle of preferably between 1 ° and 3 ° from the Vertical is inclined toward a side facing away from the shelves. As an alternative or in addition, the shelves can also be designed such that their base surfaces, when unloaded, are inclined from the horizontal to rise away from the rear wall by a small angle of preferably between 2 ° and 4 °.

A shelf of the type described here can have different sizes depending on the intended use. Appropriate designs have a height of between 60 cm and 3 m, a width of between 30 cm and 1.5 m with a typical shelf depth of between 20 cm and 80 cm. Such shelves are well suited as a kit for uncomplicated assembly by a user.

A shelf according to the invention, which is made of a foldable, flat material such as cardboard or the like, thus has a shelf support and at least one insertable shelf, the shelf having at least one flap articulated to the shelf via a folding edge for insertion into a slot in the shelf support in such a way that the shelf has a base area and wall parts connected to the base area via buckled edges, that the tab is arranged on one of the wall parts or an extension of one of the wall parts and that the slot is above a level defined by the base area when the shelf is set up , In typical designs, the shelf bracket has a rear wall, but this is not necessarily the case. Versions are also conceivable in which the shelf support has no rear wall. The shelf support can then be formed, for example, by an open frame in which the shelves hang between two side walls. Such a shelf offers a particularly transparent sight. All of the features listed in the subclaims can be realized with the advantages already mentioned in any combination, even with shelves of this type without a rear wall. Further advantageous additional features that can be realized in all conceivable combinations in shelves according to the invention with or without a rear wall result from the exemplary embodiments described below.

The shelf shown in Fig. 1 consists of a shelf support 1 and four shelves 2 and is made entirely of corrugated cardboard. The shelf support 1 has a rear wall 3 and two mutually opposite side walls 4, each of which is connected to the rear wall 3 via a folding edge. Each of the two side walls 4 consists of a total of four cardboard layers, including a slit reinforcement 5 (not shown in this figure) and a leg 6 (likewise not visible in the figure), which widens at a lower end to form a likewise concealed foot 7. The two remaining layers of each side wall 4 are in turn connected to each other via a buckling edge and take the slit reinforcement 5 and the leg 6 in the middle. Each shelf 2 has a base area 8 and wall parts 9 connected to this base area 8 each via a folding edge. A flap 10, which cannot be seen in the figure, is articulated on two side wall parts 9 of each shelf 2 by means of a further folding edge, with which the shelf 2 is inserted into slots 11 in the side walls 4 of the shelf support 1. Each slot 11 and the tab 10 inserted therein lies above one through the base 8 of the corresponding one Shelf 2 defined levels by a vertical distance, which (shown in the figure to the left of the shelf as a vertical double arrow) corresponds to about half a shelf depth (shown below the shelf as a horizontal double arrow).

As a result of this construction, the shelves 2 essentially hang on the tabs 10 which are articulated on the side walls 9 or on extensions of the side walls 9. This makes a very transparent design possible, in which the side walls 4 have a significantly smaller depth than the shelves 2, with extremely high stability being achieved despite the use of cardboard as the material. A shelf of the type shown in this figure is particularly well suited for displaying goods, in particular because of the transparent construction also makes it easy to access the shelves 2 from the side, because of its inexpensive and material-saving manufacture and because of its ease of installation and high resilience.

The slots 11 are inclined at an angle of approximately 30 ° from the vertical in the illustrated shelf, so that a perpendicular removed from the center of a slot 11 intersects the level of the base area 8 of the corresponding shelf 9 at a depth which, under normal use, is the focus load corresponds to this shelf. The wall part 9 which connects the tab 10 inserted into that slot 11 to the base 8 is thereby subjected to tension when the shelf 2 is loaded so that a force is transmitted at an edge of the slot 11 with a direction perpendicular to this edge. For a given amount of material, this leads to maximum resilience and prevents tearing from the side on the fold edge connecting the tab 10 to the wall part. In the illustrated embodiment of the invention, the concealed feet 7 are turned inside out by a base part 12, which, in addition to a further increase in stability, results in a further shelf-like compartment at ground level.

In Fig. 2 the shelf of Fig. 1 is pulled apart again and shown partially disassembled. In particular, there is also shown a single shelf 2, in which, in addition to the base 8 and the wall parts 9, the tabs 10 can also be seen, with which the shelf is to be inserted into the shelf support 1. On the individually illustrated shelf 2, an adhesive flap 13 can also be seen, which is connected to the base area 8 via a buckling edge and is arranged at a border of this base area 8 and is used for gluing to the rear wall 3 of the shelf support 1. Even if the shelf 2 is glued to the shelf bracket 1 with the adhesive tab 13, the shelf can be folded very compactly by pulling the tabs 10 out of the corresponding slots 11, after which the shelf 2 with its base 8 flat against the rear wall 3 of the Shelf support 1 can be folded. However, the gluing can also be dispensed with; as a further possibility, instead of the adhesive flap 13, one or two further flaps can be attached to the corresponding edge of the base area 8 for insertion into additional slots 14 (not shown in this figure) on the rear wall 3 Visible in the figure, partially pulled out, are the two legs 6, each widened to a foot 7 at a lower end. Below this is the shelf-like base part 12, with which the feet 7 are to be rolled up. The bottom part 12 also has an adhesive tab 13 for gluing to the rear wall 3 of the shelf support 1. Here, too, the gluing is not absolutely necessary, it is advisable to glue points at locations that are marked with a curl in the figure. The corrugated cardboard, from which the shelf shown is made, can be untreated or at least painted in one or two sides at a desired color in a desired color. The feet 7 are cut in such a way that the shelf support 1, when the shelf is set up, has a rear wall 3 inclined by approximately 1 ° in a direction facing away from the shelves 2 when the shelves 2 are not loaded. This allows a slight yielding to be compensated for, so that the shelf is straight when the shelves 2 are loaded. For the same reason, the shelves 2 are designed so that their base 8 is inclined upward by about 2 ° away from the rear wall 3 when the shelf 2 is not loaded. The shelf shown here has a height of about 2 m, a width of the rear wall 3 of about 70 cm and a depth of the shelves 2 of about 40 cm.

Fig. 3 shows blanks of components from which the carrier 1 of the shelf from Figs. 1 and 2 is composed. From left to right you can see a double wall 3 'serving as a reinforcement wall, a component forming the rear wall 3 and the side walls 4, a slit reinforcement 5, a leg 6 with foot 7 and the bottom part 12 in the unfolded state. All the components shown are made of corrugated cardboard cut with a vertical wave shape with the orientation shown. With the exception of the leg 6 with the foot 7, the corrugated cardboard has a wall thickness of 3 mm and has a single corrugation position, only the corrugated cardboard which forms the leg 6 with the foot 7 is corrugated four times with a wall thickness of 12 mm. Kink lines are here as well as in the figures. 6 and 8 drawn as dashed lines and executed as crease lines. The rear wall doubling 3 'can be glued to the rear wall 3 by point gluing, the easiest at points marked there, but it is also possible to glue over a larger area as well as a glue-free clamping between the side walls 4. The rear wall doubling 3', which is when the shelf is set up becomes part of the rear wall 3, has additional slots 14, into which additional tabs of the shelves 2, not shown in this figure, can be inserted if necessary. Points are drawn with dots under each of the additional slots 14, where instead a shelf 2 can be glued in place in a foldable manner. The component for the rear wall 3 with the side walls 4 also has adhesive tabs 13, provided for gluing the side walls 4 after a buckling around the fold edges, so that between two resulting layers, the slot reinforcement 5, which has slots 11 corresponding to the side walls 4, and the leg 6 can be inserted. The foot 7 comes to lie in an incision on a lower edge of the shelf support 1 partially between two layers of the side wall 4. 3 clearly shows that a shelf according to the invention is particularly well suited as a kit.

Another embodiment of a shelf according to the invention can be seen in FIG. Here too, a single shelf 2 is shown above the shelf. In a departure from the previously described shelf, the shelves 2 with the tabs 10 arranged on wall parts 9 of the shelves 2 are to be inserted into the slots 11 on mutually facing sides of the side walls 4. This creates a different, technical Overall impression showing less open aspects. Identical features are again identified by the same reference numerals as in the figures described above, as well as in the following figures.

FIG. 5 shows another variant of a shelf according to the invention. In contrast to the shelves from FIGS. 1 to 4, the shelf support 1 of this shelf has a closed, essentially rectangular horizontal cross section. For this purpose, the rear wall 3 and the two side walls 4 which are essentially perpendicular to the rear wall 3 and which here again have the slots 11 are supplemented by an additional wall 15 which runs essentially parallel to the rear wall 3. Overall, the carrier 1 thus has essentially a cuboid shape and is particularly resistant to torsion and bending. The additional wall 15 is connected to one of the side walls 4 via a crease line which is again designed as a crease line, and is glued to the other side wall 4 with the aid of an adhesive flap 13 which is not visible here. Also not shown in this figure is an inner profile 16 which is shown in FIG a cavity formed by the rear wall 3, the side walls and the additional wall 15 is inserted in such a way that the walls mentioned are each in two layers. The inner profile 16 increases the rigidity of the carrier and at the same time serves to abut the tabs 10 of the shelves 2, which are likewise not visible in this figure and are inserted into the slots 11, thereby preventing these tabs 10 from slipping. In the shelf of similar construction shown, designs of shelves according to the invention are also possible in which the shelf support 1 is designed as a hollow profile with a polygonal, for example hexagonal or octagonal cross section.

FIG. 6 shows the shelf support 1 of the shelf from FIG. 5, which is broken down into components. On the left, a component can be seen which, with the rear wall 3, the side walls 4 and the additional wall 15, forms four outer walls of the support, which are shown in the figure broken lines drawn in dashed lines are interconnected and can be glued together with an adhesive flap 13 to form a cavity. The rear wall 3 has additional slots 14 for inserting additional tabs of the shelves 2, not shown here.

On the right next to it, in the unfolded state, the inner profile 16 can be seen, consisting of four walls, which are connected to one another by crease lines which are also designed as crease lines. The component also has an adhesive flap 13 for gluing to one of the walls, which forms a double wall 3 ', but this gluing is not necessary. Finally, on the right, a leg 6 with a foot 7 can be seen, above it the base part 12. All of the components shown again consist of corrugated cardboard. In the base part 12, both a horizontal and a vertical wave pattern with the orientation shown are possible, which have other components of the carrier each have a vertical waveform. 3 applies accordingly to the wall thickness and number of corrugated layers in the corrugated cardboard.

The shelf shown in side view in FIG. 7 is constructed like the shelf from FIGS. and 5 and 6, it differs from this in that shelves 2 are attached to two sides of the shelf support 1 and that their base surfaces 8 are inclined sloping away from the shelf support 1. The slots 11 for inserting the tabs 10, which are not visible here, are arranged vertically in this shelf, such a slot 11 being able to accommodate two tabs 10 of two shelf bases 2 arranged opposite one another. The feet 7, which are again covered by a base part 12, are embodied symmetrically as two-sided widenings in the figure, which are not visible between the outer side walls 4 and corresponding walls of an inner profile 16, likewise not visible here, which are inserted in this shelf. They support this shelf to the front and to the rear.

Finally, FIG. 8 shows three different shelves 2 as blanks, each consisting of corrugated cardboard with a corrugated layer and a thickness of 3 mm, the corrugated cardboard having a horizontal corrugation with the orientation shown in the figure. However, it is also possible to use corrugated cardboard with two or more corrugated layers and / or with a vertical wave profile with this orientation, as well as corrugated cardboard with greater or lesser wall thickness. Creasing lines, which serve as crease edges when assembling the shelves 2 and a corresponding shelf, are drawn in the figure as dashed lines. The shelves 2 each have a base area 8 and in particular two lateral wall parts 9, to each of which a tab 10 is connected for insertion into the shelf by means of a buckling edge. This last-mentioned crease edge is designed as two parallel crease lines, the distance between these crease lines corresponding approximately to one or two wall thicknesses. This makes it easier to bend this folding edge by about 180 °, taking into account the fact that the wall part 9 and the tab 10 with the shelf installed, with the side wall 4 not shown in this figure and possibly one Take slot reinforcement 5, also not shown here, one or two layers of cardboard between them. The shelves 2 are cut in such a way that these buckling edges form an angle of at least 30 ° with the wave profile, which ensures sufficient stability on the buckling edges which are loaded in a direction essentially transversely to the corresponding buckling edge when the shelf 2 is suspended and loaded.

The shelves 2 each have one or two edges of their base area 8 card edges 17, which, each folded by two folded edges, form 9 additional walls delimiting the base areas 8 in addition to the side wall parts. The three shelves 2 shown differ in that the shelf 2 shown in the figure on the left only hangs on the tabs 10, whereas the shelf 2 shown in the middle has two additional slots 18 on an edge of the base 8, with which it can be inserted into additional tabs 14 (not shown here) on a rear wall 3 of a shelf. The shelf 2 shown on the far right has an adhesive tab 13 for sticking to a rear wall 3 of a shelf instead of the additional tabs 18 for insertion. The further tabs 18 of the shelf shown in the middle are punched out or cut out of the base 8, whereby in this shelf 2 the base 8 has two layers, which are connected by a bent edge to be bent through 180 °. All shelves 2 shown are cut out of a single piece of cardboard and can be assembled by simply folding and inserting them, if necessary with simple gluing.

The examples of various shelves or shelf supports according to the invention shown in the following figures (FIGS. 9 to 12) show features already described which are identified by the same reference numerals. In a departure from the shelves described with reference to the previous figures, the shelf shown in FIG. 9 has different shelves 2. The example shown illustrates that the corresponding slots 11 can be inclined to different degrees. Two of the slots 11 are even arranged horizontally. 10, the upper three slots 11 are widened and triangular in shape (a heart-shaped shape of the slots 11 is also possible) and, like the lower two slots 11, serve to hold two shelf bases 2 arranged opposite one another. A shelf can be seen in FIG. 11, in which the slots 11 are arranged on the rear wall 3 for receiving the tabs 10 which cannot be seen here. An inner profile 16 (or core), which is half pulled out here and also forms a second position of the walls of the shelf support 1 in addition to a supporting function, is also clearly visible. Finally, FIG. 12 shows a shelf support 1 for a hexagonal basic shape for a shelf according to the invention, again with a core or inner profile 16 to be inserted, which is shown partially pulled out in the figure.

Further features of advantageous embodiments of the invention, which can be combined in any way with the features of shelves according to the invention which have already been described, are described with reference to the remaining FIGS. 13 to 19 explained. Recurring features are again provided with the same reference symbols, for explanations supplement the exemplary embodiments already described above directed.

In advantageous embodiments of shelves according to the invention, the shelf support 1 can have additional layers, preferably cardboard layers, as reinforcements 19. Such reinforcements 19 can advantageously be provided in particular where the shelf support 1 has slots 11 for receiving the tabs 10. A particularly good fit of the tabs 10 and thus a particularly secure hold of the shelves 2 on the shelf support 1 now results if such a reinforcement 19 has a corresponding recess 20 in each case where a tab 10 comes to rest when the shelf 2 is mounted. A particularly advantageous effect in this regard is achieved if the corresponding reinforcement 19 has a wall thickness corresponding to the tabs 10, that is to say the same thickness as the corresponding tab 10.

Cuts for two shelf supports 1 of this type are shown in FIGS. 13 and 14. Both shelf brackets 1 not only each have a reinforcing rear wall doubling 3 ', but also reinforcements 19, which reinforce the side wall parts 9, at the same time form legs 6 and, in the case of FIG. 14, feet 7 of the corresponding shelf bracket 1 and recesses 20 in the manner described have, in which the tabs 10 of shelves 2 not shown here come to rest when the shelf is set up. The reinforcements 19 mentioned are made from corrugated cardboard which is just as thick as the tabs 10. Unlike the shelf supports shown in FIG. 13, the cutouts 20 in the reinforcements 19 of the shelf support 1 from FIG. 14 are not closed , but arranged on an edge of the respective reinforcement 19. To increase 14, two further reinforcements 19 'are provided for each of the side walls 4 in the case of the shelf support 1 from FIG. 14, these additional reinforcements 19' again forming legs 6 and feet 7 for the corresponding shelf. The reinforcements 19 and 19 'can be glued to adjacent layers in order to increase the stability, ie in the examples shown with a further reinforcement 19 or 19' and / or a side wall 4.

The tabs 10 for hanging the shelves 2 on the shelf support 1 can also be arranged on a side of the shelf support 1 facing away from the shelf bottoms 2 in likewise advantageous embodiments of the invention. In the case of a closed shelf support 1 which is typical of corresponding designs and which can have, for example, a cuboid shape, the slots 11 would then be provided on an additional wall 15 parallel to the actual rear wall 13. Shelves designed in this way are particularly resilient because a force is then introduced over the tab 10 flatly and via an additional folding edge 21.

A view of a corresponding shelf is shown in FIG. 15, a cut of a corresponding shelf 2 in FIG. 16. The closed shelf support 1 of the shelf shown in FIG. 15 is filled by several layers of cardboard not recognizable in the figure, thereby the shelf support 1 receives a special stability. The cardboard layers mentioned can be glued to one another and to an outer, surrounding cardboard layer of the shelf support 1. In the exemplary embodiment shown, the outer layer, which has the slots 11, is cut symmetrically, with two where a dashed line can be seen in the figure Cut edges run close to each other or touching each other in parallel. The cardboard layers mentioned here perform the same function as the inner profile 16 in the shelf support shown in FIG. 6. Corrugated cardboard is a suitable material for the cardboard layers, but it is equally possible and advantageous for weight reasons to use honeycomb cardboard or other light, flat materials. The use of honeycomb cardboard instead of or in addition to corrugated cardboard is also possible for any other components of this or other shelves according to the invention.

Finally, a further shelf according to the invention is shown in a perspective view in FIG. 17, which, contrary to the previously described exemplary embodiments, is designed without a rear wall. The shelf support 1 here therefore has only two side walls 4 and an upper cross connection 22 and a lower cross connection 23, which together with the side walls 4 form a frame. The shelves 2 each have a total of four tabs 10 (not shown here), two of which are to be hooked into two slots 11 of each side wall 4. The shelf without shelves from FIG. 17 is distinguished by the fact that it appears particularly transparent.

In order to prevent the tabs 10 from jumping out of the slots 11 and thus preventing the shelves 2 from jumping out of the shelf support 1 of a shelf according to the invention, in the case of particularly advantageous shelves 2 for shelves according to the invention, the side wall parts 9 can be doubled by an additional layer 24, which is shaped in such a way that it blocks the corresponding tab 10 when the shelf 2 is mounted by acting as a bolt, so to speak.

18 shows a cut of a corresponding shelf 2, two side wall parts 9 of this shelf 2 being designed in accordance with two different designs. On the left in the picture, an additional layer 24, designed as a carded edge 17, can be seen, which, when the corresponding shelf is installed, is folded over the actual wall part 9 after inserting the corresponding flap 10 in such a way that this side wall part 9, the flap 10 and the covers corresponding slot not shown here and thus secures the tab 10 against jumping out. This is possible because the additional layer 24 mentioned has larger dimensions on the left in the picture than the side wall part 9 provided with the tab 10. To make it easier to place the additional layer 24 on the side wall part 9, the additional layer 24 has a kink line 25 around which the additional layer 24 can be folded. Another, albeit comparable, safeguard against the corresponding tab 10 jumping out can be seen on the right in the picture. An additional layer 24 designed as a card edge 17 for application to the corresponding lateral wall part 9 can also be seen there. Here, however, the additional layer 24 has dimensions which correspond to the side wall part, but instead has a securing tab 26 which is articulated via a folding edge and, after the additional layer 24 has been placed on the side wall part 9, with the corresponding slot 11 in register comes to lie. It is now provided to insert the securing tab 26 into the slot 11 in addition to the tab 10 which is then already resting in the slot 11, as a result of which the securing tab 26 acts as a bolt and prevents the tab 10 from jumping out.

Another shelf 2 for a shelf according to the invention is finally shown in FIG. 19. Two details are worth mentioning here. On the one hand, the two tabs 10 of the shelf 2 shown here are each designed in the shape of approximately half a heart. This shape allows a particularly simple insertion of the tabs 10 into the corresponding slots 11, see also the side view of the corresponding shelf on the right in the picture. By means of a special tab shape of the type described and illustrated, it is possible to hang the shelf 2 by simply inserting the already bent tabs 10 from above into the slots 11 inclined here. As a further detail, the shelf 2 shown, which is designed to be inclined slightly backwards when the shelf is erected, has a second shelf 27 which is placed or glued to the base 8 and is bent around an edge in such a way that it has a right-hand edge Forms an angle, a bent part coming to rest against the rear wall 3 of the shelf support 1. In the illustrated embodiment, the shelf 2 is given a shape of a storage compartment with a right angle 28 formed by the second floor 27 at a lower end (despite the inclined base area 8) and is therefore particularly suitable for storing rectangular objects such as books.
