Erfindungsgemäß sind die Grundfläche und die Verstärkungslage dabei einstückig aus einem gemeinsamen Zuschnitt aus Pappe gebildet und über mindestens eine Knicklinie an einem vorderen oder hinteren Rand der Grundfläche und der Verstärkungslage miteinander verbunden, wobei die Verstärkungslage außerdem mindestens zwei durch Schwächungen vorgegebene, innerhalb eines Grundrisses der Grundfläche verlaufende, also auf der Grundfläche liegende Knicklinien aufweist, die die Verstärkungslage so zu falten erlauben, dass ein Abstand zwischen den zwei Fortsätzen reduziert wird, um die der die Verstärkungslage bildende Zuschnitt jedoch bei fertig aufgestelltem Regal nicht geknickt ist.The proposed paperboard shelf comprises a support and at least one shelf supported by the support, the support having two sidewalls each having an outer layer and an inner layer facing the other sidewall, and wherein the shelf has a base and at each of two lateral edges the base is connected to a respective one of the side walls by a tab which is pushed through an opening in the inner layer of this side wall, so that a projection of the tab rests on a lower edge of the opening. In this case, there is a reinforcing layer at least as far as possible covering the base surface, wherein the reinforcing layer has two projections extending over the tabs and widening the reinforcing layer on two lateral edges, which protrude above the projection of one of the tabs into the opening receiving the respective tab. According to the invention, the base surface and the reinforcing layer are integrally formed from a common blank made of cardboard and interconnected via at least one crease line at a front or rear edge of the base and the reinforcing layer, wherein the reinforcing layer also at least two predetermined by weakening, within a floor plan of the base extending, ie lying on the base surface bending lines, which allow the reinforcing layer to fold so that a distance between the two extensions is reduced, by which the reinforcing layer forming blank is not kinked in fully erected shelf.
Die beim fertiggestellten Regal bzw. Regalboden innerhalb des Grundrisses der Grundfläche verlaufenden Knicklinien machen es möglich, die Verstärkungslage problemlos durch Umklappen des Zuschnitts um die mindestens eine Knicklinie, die die Verstärkungslage mit der Grundfläche verbindet, auf die Grundfläche aufzulegen, wenn der Regalboden bereits mit den Laschen in den Träger eingehängt ist. Dabei können die Fortsätze der Verstärkungslage dank der innerhalb des Grundrisses verlaufenden Kicklinien ungehindert zwischen den Seitenwänden des Trägers bis zu den Öffnungen gebracht werden, indem die Verstärkungslage so weit um diese Knicklinien geknickt wird, dass der Abstand zwischen den zwei Fortsätzen der Verstärkungslage nicht mehr zu groß dafür ist. Daher ist es möglich, die Grundfläche und die Verstärkungslage aus einem gemeinsamen Zuschnitt zu bilden, was sowohl im Hinblick auf eine möglichst einfache Herstellung aller benötigter Komponenten des Regals als auch im Hinblick auf ein möglichst einfaches Aufstellen des Regals von Vorteil ist. Es ist sogar möglich, den ganzen Regalboden einstückig aus dem genannten Zuschnitt zu bilden.The buckling lines running in the finished floor or shelf within the floor plan of the base make it possible to hang the reinforcing layer by folding the blank around the at least one bending line connecting the reinforcing layer to the base surface, if the shelf already with the Lugs is hung in the carrier. The extensions of the reinforcing layer can be brought freely between the sidewalls of the carrier to the openings thanks to the running inside the outline Kicklinien by the reinforcing layer is bent so far around these creases that the distance between the two extensions of the reinforcing layer is no longer too large for that is. Therefore, it is possible to form the base and the reinforcing layer of a common blank, which is advantageous both with regard to the simplest possible production of all required components of the shelf as well as in terms of the simplest possible installation of the shelf. It is even possible to form the entire shelf in one piece from said blank.
Die genannten Öffnungen sind typischerweise als längliche Schlitze ausgeführt. Wenn der Regalboden in den Träger eingehängt ist, sind die Laschen typischerweise nach unten abgewinkelt, so dass sie zwischen den Lagen der Seitenwand liegen. Die Schlitze, sollten so breit sein, dass sie die Laschen gut aufnehmen können. Sie müssen allerdings nicht notwendigerweise vollständig ausgeschnitten sein. Stattdessen können sie auch durch längliche Klappen gebildet sein, die jeweils durch einen längs eines unteren Randes des Schlitzes verlaufenden und an zwei Enden des Schlitzes nach oben fortgesetzten und dadurch U-förmigen einfachen Schnitt realisiert sein können und die sich unter Umständen einfacher herstellen lassen als vollständig ausgeschnittene Schlitze. Zum Einstecken der entsprechenden Lasche in den Schlitz kann die Klappe dann in den Zwischenraum zwischen den Lagen der Seitenwand hinein nach oben aufgeklappt werden. Um das zu erleichtern, kann zwischen zwei Enden des Schnittes eine Knicklinie vorgegeben sein, beispielsweise durch eine Rill-Linie oder eine ähnliche Schwächung, die ein Scharnier der Klappe bildet und einen oberen Rand des von der Klappe freigegebenen Schlitzes definiert. Die Laschen können aus dem selben gemeinsamen Zuschnitt gebildet sein wie die Grundfläche und die Verstärkungslage.The said openings are typically designed as elongated slots. When the shelf is hung in the carrier, the tabs are typically angled down so that they lie between the layers of the side wall. The slots should be so wide that they can pick up the tabs well. However, they do not necessarily have to be completely cut out. Instead, they can also be formed by elongated flaps, which can be realized in each case by a along a lower edge of the slot extending and continued at two ends of the slot upwards and U-shaped simple cut and can be easier to produce than completely cut out slits. For insertion of the corresponding tab in the slot, the flap can then be folded up into the space between the layers of the side wall. To facilitate this, a crease line may be provided between two ends of the cut, for example by a score line or similar weakening which forms a hinge of the flap and defines an upper edge of the slot cleared by the flap. The tabs can be formed from the same common blank as the base and the reinforcing layer.
Bei dem vorgeschlagenen Regal kann es sich insbesondere um einen Verkaufsständer handeln. Typischerweise wird das Regal natürlich mehrere Regalböden beschriebener Art aufweisen.The proposed shelf may in particular be a sales stand. Typically, the shelf will of course have several shelves of the type described.
Eine Ausführung, die sich durch einen besonders einfachen Aufbau des mindestens einen Regalbodens auszeichnet, sieht vor, dass die innerhalb des Grundrisses der Grundfläche verlaufenden Knicklinien der Verstärkungslage jeweils von einer Ecke der Verstärkungslage am vorderen oder hinteren Rand der Verstärkungslage bis zu einem gegenüberliegenden freien Rand der Verstärkungslage verlaufen und sowohl mit diesen zwei Rändern als auch mit den seitlichen Rändern einen nicht verschwindenden Winkeleinschließen, vorzugsweise einen Winkel von zwischen 20° und 70°, beispielsweise etwa 45°.An embodiment, which is characterized by a particularly simple construction of the at least one shelf, provides that extending within the floor plan of the base creases of the reinforcing layer each from a corner of the reinforcing layer at the front or rear edge of the reinforcing layer to an opposite free edge of Reinforcement and extend both with these two edges as well as with the lateral edges of a non-vanishing angle, preferably an angle of between 20 ° and 70 °, for example about 45 °.
Bei einer anderen Ausführung weist der die Grundfläche und die Verstärkungslage bildende Zuschnitt an jeder der seitlichen Ränder der Verstärkungslage zwei Einschnitte auf, die von zwei Enden des dort vorgesehenen Fortsatzes ausgehen, so dass der Fortsatz durch ein Ende einer zwischen den Einschnitten liegenden Zunge gebildet wird, wobei eine der innerhalb des Grundrisses der Grundfläche verlaufenden Knicklinien die Enden der zwei Einschnitte verbindet und eine andere der innerhalb des Grundrisses der Grundfläche verlaufenden Knicklinien die zwei Einschnitte zwischen deren Enden und dem Fortsatz miteinander verbindet. Der Abstand zwischen den beiden Fortsätzen kann dann zum Einhängen des Regalbodens in den Träger reduziert werden, indem die genannten Zungen vor dem Einschieben der Fortsätze in die Öffnungen um die die Enden der Einschnitte miteinander verbindenden Knicklinien nach oben geknickt werden und gleichzeitig in sich geknickt werden durch Umbiegen um die anderen Knicklinien, die zwischen dem jeweiligen Fortsatz und den Enden der Einschnitte quer über die jeweilige Zunge laufen, in die entgegengesetzte Richtung. Die Fortsätze können dann in die Öffnungen geschoben werden, indem der Zuschnitt an den genannten Knicklinien wieder gestreckt wird, bis dort kein Umbug mehr vorliegt und die Verstärkungslage mit den Zungen in einer Ebene liegt.In another embodiment, the blank forming the base and reinforcing ply has, on each of the lateral edges of the reinforcing ply, two indentations extending from two ends of the appendage provided there, such that the appendix is formed by one end of a tongue located between the incisions, wherein one of the crease lines extending within the floor plan of the base joins the ends of the two notches, and another of the crease lines extending within the floor plan merges the two notches between the ends thereof and the extension. The distance between the two extensions can then be reduced for hanging the shelf in the carrier by the said tongues are folded up before inserting the projections into the openings around the edges of the incisions interconnecting crease lines and at the same time be kinked in by Bend around the other crease lines that run across the respective tongue between the respective extension and the ends of the incisions, in the opposite direction. The extensions can then be pushed into the openings by the blank is stretched again at the aforementioned fold lines until there is no more Umbug and the reinforcing layer lies with the tongues in a plane.
Der Regalboden kann besonders einfach hergestellt und gleichzeitig besonders stabil und belastbar ausgeführt werden, wenn die Laschen zusammen mit einem den Ansatz der jeweiligen Lasche bildenden Verbindungsstück aus einem Inneren der Grundfläche herausgeschnitten sind, wobei das Verbindungsstück über mindestens eine erste Knicklinie - vorzugsweise über zwei dicht nebeneinander verlaufende parallele Knicklinien - mit der Grundfläche und über eine zweite Knicklinie mit der Lasche verbunden ist, wobei der Zuschnitt an der mindestens einen ersten Knicklinie um 180° umgebogen ist, so dass das Verbindungsstück unten an der Grundfläche anliegt, und wobei die zweite Knicklinie entlang eines seitlichen Randes der Grundfläche zu liegen kommt. Typischerweise wird die mindestens eine erste Knicklinie dabei parallel zum seitlichen Rand der Grundfläche verlaufen, sie kann aber mit dem seitlichen Rand auch einen Winkel von z.B. 45° einschließen.The shelf can be made very simple and at the same time run very stable and resilient, when the tabs together with an approach of the respective tab-forming connector from an inner surface of the base are cut, wherein the connecting piece via at least one first bending line - preferably via two closely juxtaposed parallel fold lines - is connected to the base and a second crease line with the tab, wherein the blank at the at least one first crease line to 180 ° is bent so that the connector abuts the bottom of the base, and wherein the second crease line comes to lie along a lateral edge of the base. Typically, the at least one first crease line will run parallel to the lateral edge of the base, but it may also include an angle of eg 45 ° with the lateral edge.
Um ein Verrutschen oder Herausfallen von auf dem Regalboden lagernden Gegenständen zu vermeiden kann der Regalboden eine die Grundfläche begrenzende Blende aufweisen, die aus dem selben gemeinsamen Zuschnitt gebildet sein kann und gegenüber der Grundfläche abgewinkelt ist. Dabei kann sich die Blende insbesondere entlang des vorderen oder hinteren Randes der Grundfläche erstrecken, an dem die Verstärkungslage über Knicklinien mit der Grundfläche verbunden ist, wobei die Blende dann dort durch zwei aneinandergelegte Streifen des Zuschnitts gebildet ist, die über mindestens eine dieser Knicklinien miteinander verbunden sind, wobei ein erster dieser Streifen über eine weitere dieser Knicklinien mit der Grundfläche und der andere dieser Streifen über eine weitere dieser Knicklinien mit der Verstärkungslage verbunden ist. In diesem Fall sind die Grundfläche und die Verstärkungslage also über mindestens drei Knicklinien miteinander verbunden. Die so gestaltete Blende trägt auch zur Stabilität und zu einem ansprechenden Erscheinungsbild des Regalbodens bei, ohne dessen Herstellung aufwändiger zu machen.In order to prevent slippage or falling out of objects stored on the shelf, the shelf may have a base limiting aperture, which may be formed from the same common blank and is angled relative to the base. In this case, the panel may extend in particular along the front or rear edge of the base, where the reinforcing layer is connected via creases to the base, wherein the panel is then formed there by two juxtaposed strips of the blank, which are interconnected via at least one of these fold lines are, wherein a first of these strips is connected via a further of these creases with the base and the other of these strips via another of these creases with the reinforcing layer. In this case, the base area and the reinforcing layer are connected to each other via at least three crease lines. The so designed aperture also contributes to the stability and an attractive appearance of the shelf, without making its production more complex.
Die Blende kann außerdem zwei entlang der seitlichen Ränder verlaufende Abschnitte aufweisen, an denen jeweils eine Lasche angelenkt ist, die zwischen den genannten Streifen zu liegen kommt, wobei die entlang der seitlichen Ränder verlaufenden Abschnitte der Blende jeweils eine Ausnehmung aufweisen, durch die die Fortsätze der Verstärkungslage hindurch ragen. Auch gegenüber des Randes, an dem die Grundfläche und die Verstärkungslage miteinander über Knicklinien verbunden sind, kann ein Abschnitt der Blende vorgesehen sein, der als Krempelrand ausgeführt und um Laschen herumgelegt sein kann, die dann ebenfalls an den längs der seitlichen Ränder verlaufenden Abschnitten der Blende angelenkt sind. Dabei kann es vorgesehen sein, dass die entlang der seitlichen Ränder verlaufenden Abschnitte der Blende als Griffe geformt sind, die den Regalboden wie ein Tablett zu halten erlauben.The visor may also have two sections extending along the lateral edges, to each of which a tab is hinged, which comes to lie between said strips, wherein the edges along the side edges extending portions of the aperture each having a recess through which the extensions of the Protect reinforcing layer through. Also, with respect to the edge at which the base and the reinforcing layer are connected to each other via crease lines, a portion of the aperture can be provided, which is designed as a carding edge and tabs can be wrapped around, which are then also hinged to the longitudinal edges of the extending portions of the aperture. It may be provided that the sections along the lateral edges extending the aperture are shaped as handles that allow to hold the shelf like a tray.
Die Stabilität und Belastbarkeit des Regals kann noch weiter erhöht werden, wenn die Grundfläche ebenfalls zwei über den zwei Laschen liegende und die Grundfläche dort verbreiternde Fortsätze aufweist, die zwischen dem Ansatz der jeweiligen Lasche und dem darüber liegenden Fortsatz der Verstärkungslage in die die jeweilige Lasche aufnehmende Öffnung hineinragen. Diese Fortsätze können gebildet sein aus Teilen des Zuschnittes, die durch die erwähnten Ausnehmungen in den entlang der seitlichen Ränder verlaufenden Abschnitten der Blende übrig bleiben. Typischerweise liegen die Fortsätze der Verstärkungslage mit den Fortsätzen der Grundfläche in Deckung, so dass mit dem Ansatz der Lasche, dem Fortsatz der Grundfläche und dem Fortsatz der Verstärkungslage drei den Regalboden tragende oder stabilisierende Lagen auf dem unteren Rand der Öffnung aufliegen, was eine ausgesprochen hohe Belastbarkeit des Regalbodens mit sich bringt. Im Hinblick auf die Stabilität ist es dabei vorteilhaft, wenn der Ansatz der Lasche, der Fortsatz der Grundfläche und der Fortsatz der Verstärkungslage die Öffnung möglichst vollständig ausfüllen. Insbesondere in diesem Fall können die zusätzlich zu den Fortsätzen der Verstärkungslage vorgesehenen Fortsätze der Grundfläche auch verhindern, dass sich die Grundfläche und die Verstärkungslage relativ zueinander verschieben und dass die Blende dadurch aus ihrer gegenüber der Grundfläche abgewinkelten Position heraus kippt.The stability and resilience of the shelf can be further increased if the base also has two over the two tabs and the base there widening extensions that between the approach of the respective tab and the overlying extension of the reinforcing layer in which the respective tab receiving Protrude into the opening. These extensions may be formed from parts of the blank remaining through the recesses mentioned in the sections of the panel along the lateral edges. Typically, the extensions of the reinforcing layer with the extensions of the base cover, so that rest with the approach of the tab, the extension of the base and the extension of the reinforcing layer three shelf-supporting or stabilizing layers on the lower edge of the opening, which is a decidedly high Resilience of the shelf brings with it. In terms of stability, it is advantageous if the approach of the tab, the extension of the base and the extension of the reinforcing layer fill the opening as completely as possible. In particular, in this case, the extensions of the base provided in addition to the extensions of the reinforcing layer can also prevent the base and the reinforcing layer from shifting relative to each other and thereby tilting the shutter out of its angled position relative to the base.
Im Hinblick sowohl auf die Stabilität als auch das Erscheinungsbild des Regalbodens ist es besonders vorteilhaft, wenn die Verstärkungslage einen Grundriss hat, der dem Grundriss der Grundfläche entspricht.With regard to both the stability and the appearance of the shelf, it is particularly advantageous if the reinforcement layer has a floor plan that corresponds to the floor plan of the base.
Das vorgeschlagene Regal kann vollständig oder zumindest teilweise aus Wellpappe gebildet sein, die sich bei gegebener Materialstärke durch besonders hohe Stabilität auszeichnet. Das gilt insbesondere für den genannten Zuschnitt und/oder alle genannten Lagen des Trägers, der aus einem oder mehreren Pappzuschnitten gebildet sein kann. Die genannten Knicklinien können jeweils durch eine Rill-Linie und/oder eine Perforation und/oder eine andere Materialschwächung vorgegeben sein, um das Fertigstellen des Regals durch Falten der Zuschnitte für die Regalböden, Aufstellen des Trägers und Einhängen der Regalböden in den Träger zu erleichtern.The proposed shelf may be formed entirely or at least partially of corrugated cardboard, which is characterized by a particularly high stability for a given material thickness. This applies in particular to the blank and / or all the layers of the carrier mentioned, which may be formed from one or more cardboard blanks. The mentioned bend lines may each be predetermined by a score line and / or perforation and / or other material weakening to facilitate finishing of the shelf by folding the blanks for the shelves, placing the carrier and hooking the shelves into the carrier.

Die vordere Lage 8 liegt mittig in diesem Zuschnitt. Die inneren Lagen 6 der Seitenwände 4 sind jeweils über eine Knicklinie 10 mit der vorderen Lage 8 der Rückwand 3 verbunden. An die inneren Lagen 6 der Seitenwände 4 schließen sich außen die über die Knicklinien 7 mit den inneren Lagen 6 verbundenen äußeren Lagen 5 an, während die zwei Teilflächen 9 der hinteren Lage der Rückwand jeweils über ein Knicklinienpaar, das durch zwei parallel zueinander verlaufende Knicklinien 11 gebildet wird, mit der äußeren Lage 5 einer der Seitenwände 4 verbunden sind. Die Knicklinien 7, 10 und 11 sind jeweils durch eine gestrichelte Linie dargestellt und sind jeweils durch eine Rill-Linie vorgegeben. Stattdessen oder zusätzlich könnten sie auch durch eine Perforation oder eine andere Materialschwächung vorgegeben sein.The
Ein Abstand zwischen den zwei Knicklinien 11 jedes der Knicklinienpaare, die die äußeren Lagen 5 der Seitenwände 4 mit der hinteren Lage der Rückwand 3 verbinden, sind etwa drei- oder viermal so groß wie eine Wandstärke des Zuschnitts, also drei- oder viermal so groß wie eine Dicke oder Materialstärke der verwendeten Wellpappe. Der Abstand zwischen den zwei Knicklinien 7, die die innere Lage 6 mit der äußeren Lage 5 der jeweiligen Seitenwand 4 verbinden, ist ebenfalls größer als die Wandstärke des Zuschnitts und ungefähr oder zumindest fast so groß wie der Abstand zwischen den Knicklinien 11 der genannten Knicklinienpaare. Die Regalböden 2 werden durch jeweils eine Lasche 13 mit jeder der Seitenwände 4 verbunden ist. Dazu weisen die inneren Lagen 6 der Seitenwände 4 schlitzförmige Öffnungen 12 auf, durch die die Laschen 13 geschoben werden, so dass die Laschen 13 von einem zwischen den Lagen 5 und 6 der jeweiligen Seitenwand 4 gebildeten Zwischenraum aufgenommen werden.A distance between the two

Dabei stoßen die zwei Zuschnitte längs eines parallel zu den Knicklinien 7, 10 und 11 durch die vordere Lage 8 der Rückwand verlaufenden Randes 16 beider Zuschnitte aneinander. In diesem Fall umfasst also auch die vordere Lage 8 des Trägers 1 zwei Teilflächen umfasst, wobei jeder der zwei Zuschnitte eine dieser Teilflächen umfasst. Außerdem bildet jeder dieser Zuschnitte jeweils die Lagen 5 und 6 einer der beiden Seitenwände 4. Zwei unterschiedliche Abstände des Randes 16 zu den die vordere Lage 8 begrenzenden Knicklinien 10 sind dabei so gewählt, dass sich die aus einem ersten der zwei Zuschnitte gebildete Teilfläche der vorderen Lage 8 beim fertiggestellten Träger 1 mit der aus dem anderen der zwei Zuschnitte gebildeten Teilfläche 9 der hinteren Lage überlappt und an die letztgenannte Teilfläche 9 der hinteren Lage angeklebt ist. Auch die Teilflächen 9 sind, wie die Teilflächen der vorderen Lage, in diesem Fall nicht gleich groß gewählt, so dass eine verhältnismäßig große Überlappung beider Zuschnitte erreicht wird.The two blanks abut one another along a

Die Laschen 13, die in die Öffnungen 12 hineingeschoben werden und mit denen der Regalboden 2 dadurch in den Träger 1 eingehängt wird, sind jeweils zusammen mit einem einen Ansatz der Lasche 13 bildenden Verbindungsstück 19 aus einem Inneren der Grundfläche 17 herausgeschnitten, wobei das Verbindungsstück 19 über eine gestrichelt dargestellte erste Knicklinie oder durch zwei dicht nebeneinander verlaufende parallele Knicklinien mit der Grundfläche 17 und über eine zweite Knicklinie mit der Lasche 13 verbunden ist. Im vorliegenden Fall verläuft die erste Knicklinie dabei wie die zweite Knicklinie parallel zu einem seitlichen Rand der Grundfläche 17. Bevor der Regalboden 2 in den Träger 1 eingehängt wird, wird der den Regalboden 2 bildende Zuschnitt an der ersten Knicklinie, längs derer das jeweilige Verbindungsstück 19 mit der Grundfläche 17 verbunden ist, um 180° umgebogen ist, so dass das Verbindungsstück unten an der Grundfläche 17 anliegt und die zweite Knicklinie, längs derer die Lasche 13 an dem Verbindungsstück 19 angelenkt ist, entlang des seitlichen Randes der Grundfläche zu liegen kommt. Wenn der Regalboden 2 dann durch Einschieben der Laschen 13 in die Öffnungen 12 mit dem Träger 1 verbunden wird, kommt der Ansatz der Lasche 13 auf einem unteren Rand der jeweiligen Öffnung 12 zu liegen. Wenn der Regalboden 2 in den Träger 1 eingehängt ist, sind die Laschen 13 dann nach unten abgewinkelt und liegen so zwischen den Lagen 5 und 6 der jeweiligen Seitenwand 4.The
Der fertige Regalboden 2 weist eine aus dem selben Zuschnitt gebildete und im vorliegenden Fall umlaufende Blende 20 auf, die aus dem selben Zuschnitt gebildet ist wie die Grundfläche 17 und die Verstärkungslage 18 und die beim fertiggestellten Regalboden 2 gegenüber der Grundfläche 17 abgewinkelt ist. Diese Blende 20 erstreckt sich insbesondere entlang eines vorderen oder hinteren Randes der Grundfläche 17, an dem die Verstärkungslage 18 über vier Knicklinien mit der Grundfläche 17 verbunden ist. Diese Knicklinien sind in
Die Verstärkungslage 18 hat einen Grundriss, der einem Grundriss der Grundfläche 17 entspricht. Innerhalb dieses Grundrisses verlaufen zwei Knicklinien 25 durch die Verstärkungslage 18, und zwar jeweils von einer Ecke der Verstärkungslage 18 am vorderen oder hinteren Rand der Verstärkungslage 18, an dem diese über die zuvor genannten Knicklinien mit der Grundfläche verbunden ist, bis zu einem gegenüberliegenden freien Rand der Verstärkungslage 18, wobei die Knicklinien 25 sowohl mit diesen zwei Rändern als auch mit den seitlichen Rändern einen nicht verschwindenden Winkel von etwa 45° einschließen, ohne sich jedoch zu kreuzen.The reinforcing
Die die Verstärkungslage 18 weist zwei die Verstärkungslage 18 an den seitlichen Rändern verbreiternde Fortsätze 26 auf, die nach dem Einhängen des Regalbodens 2 in den Träger 1 über den Laschen 13 zu liegen kommen und dann über dem Ansatz jeweils einer der Laschen 13 in die die jeweilige Lasche aufnehmende Öffnung 12 hineinragen. Dabei kann die Verstärkungslage 18 so um die zwei Knicklinien 25 gefaltet werden, dass ein Abstand zwischen den zwei Fortsätzen 26 reduziert wird. Bei fertig aufgestelltem Regal ist der den Regalboden 2 bildende Zuschnitt jedoch nicht um die Knicklinien 25 geknickt. Dann liegen die Knicklinien 25 wie die ganze Verstärkungslage 18 flach auf der Grundfläche 17 auf.The reinforcing
Die Grundfläche 17 weist ebenfalls zwei Fortsätze 27 auf, die über den zwei Laschen 13 liegen und zwischen dem Ansatz der jeweiligen Lasche 13 und dem darüber liegenden Fortsatz 26 der Verstärkungslage 18 in die die jeweilige Lasche 13 aufnehmende Öffnung 12 hineinragen, wenn der Regalboden 2 in den Träger 1 eingehängt ist, und die die Grundfläche 17 dort verbreitern. Dabei liegen die Fortsätze 26 der Verstärkungslage 18 mit den Fortsätzen 27 der Grundfläche 17 beim fertigen Regalboden 2 in Deckung, so dass mit dem Ansatz der Lasche 13, dem Fortsatz 27 der Grundfläche 17 und dem Fortsatz 26 der Verstärkungslage 18 drei den Regalboden tragende Lagen des Zuschnitts auf dem unteren Rand der Öffnung 12 aufliegen, wobei der Ansatz der Lasche 13, der Fortsatz 27 der Grundfläche 17 und der Fortsatz 26 der Verstärkungslage 18 die dementsprechend dimensionierte Öffnung 12 vollständig ausfüllen.The base 17 also has two

- A shelf according to one of the claims 1 to 3, characterised in that at least one of the tabs (13) together with a connection piece (19) which forms the projection of the tab (13) is cut out of an inside of the base surface (17), wherein the connection piece (19) is connected to the base surface (17) via at least one first crease line and to the tab (13) via a second crease line, where the blank is folded over by 180° at the at least one first crease line, so that the connection piece (19) at the bottom touches the base surface (17), and wherein the second crease line comes to lie along a lateral edge of the base surface (17).
- A shelf according to one of the claims 1 to 4, characterised in that the shelf base (2) comprises a skirting (20) which delimits the base surface (17), is formed from the same common blank and is angled with respect to the base surface (17), wherein the skirting (20) extends in particular along the front or rear edge of the base surface (17), at which edge the reinforcement layer (18) is connected to the base surface (17) via crease lines, and wherein the skirting (20) is formed there by two strips (21) of the blank which are laid onto one another and which are connected to one another via at least one of these crease lines, wherein a first of these strips is connected to the base surface (17) via a further of these crease lines and the other of these strips (21) to the reinforcement layer (18) via a further of these crease lines.
- A shelf according to claim 5, characterised in that the skirting (20) comprises two sections (22) which run along the lateral edges and on each of which a tab (23) is articulated, said tab coming to lie between the mentioned strips (21), wherein each of the skirting sections (22) which run along the lateral edges comprises a recess, through which the continuations (26) of the reinforcement layer (26) project.
- A shelf according to claim 6, characterised in that the sections (22) of the skirting (20) which run along the lateral edges are shaped as grips.
- A shelf according to one of the claims 1 to 7, characterised in that the base surface (17) likewise comprises two continuations (27) which lie over the two tabs (13), widen the base surface (17) there and which, between the projection of the respective tab (13) and the continuation (26) of the reinforcement layer (18) situated there above, project into the opening (12) which receives the respective tab (13).
- A shelf according to one of the claims 1 to 8, characterised in that the reinforcement layer (18) has an outline which corresponds to the outline of the base surface (17).
- A shelf according to one of the claims 1 to 9, characterised in that the mentioned blank and/or all mentioned layers (5, 6) of the carrier (1) are formed from corrugated cardboard and/or that the mentioned crease lines (15, 15') are each predefined by a groove line and/or a perforation and/or another material weakening.
