Definitions
- the invention relates to a wall-reinforced conical stacking box as described in the top section of the claim.
- stacking crates which, when filled, are transported from one place to another, emptied there, and have to be returned to the filling location when empty.
- Containers for living plants and the like may be mentioned here, for example.
- the plants are inserted into the stacking boxes in greenhouses, then loaded onto means of transport, the boxes being stacked one on top of the other without destroying the goods in the box below, such as the living plants.
- Such a stacking is uneconomical on the return transport of the empty boxes, so the boxes are equipped in such a way that they can be stacked one inside the other and thus take up less storage space.
- a known solution consists in equipping the stacking box asymmetrically at the end faces with a projection or an outwardly projecting recess, such that in one position all boxes fit into one another, i.e. the projections on one side correspond directly with the projections on the next box and immediately. If such boxes are now stacked on top of one another in an alternating sequence in the horizontal plane rotated by 180 °, a recess in the upper box, for example, meets the projection in the lower box, so that the two lidless boxes cannot sink into one another.
- this solution has proven to be in need of improvement, since the weight that can be carried by the lower boxes is limited by the fact that the filled boxes can only be received on two sides, so that only a certain stack height can be achieved.
- the object of the invention is therefore to provide a solution with which such stacking boxes can be subjected to a higher pressure load, wherein the wall thicknesses of the box walls can be kept as small as possible.
- the reinforced wall areas of the ribs distributed around the circumference enable the individual rib and thus the entire stacking box to be subjected to high pressure, so that a high stacking height can be achieved. It is also possible to reduce the number of ribs required and the wall thicknesses of the areas of the box located between the ribs.
- each stacking box has two longitudinal sides 2 and 2 'and two end faces 3 and 3' and a box bottom 4 and 4 'and a box opening 5 and 5'.
- Both sides 2 and 3 equipped with ribs 6 and 6 ', which are distributed asymmetrically on the circumference. These ribs have on the upper part of the outer surfaces outer wall-reinforced areas 7 and 7 'and on the lower part, which is not shown in Fig. 1 and 2, but in Fig. 3 and 4 inner surfaces inner wall-reinforced areas 8 and 8'. Due to the asymmetrical arrangement of the ribs 6, the two stacking boxes 1 and 1 'depending on the location of the Ribs of the two boxes towards each other or not, ie there is an empty or full stacking.
- FIG. 3 and 4 two sections along the lines I-I in Fig. 1 and II-II in Fig. 2 are shown.
- a possible embodiment of the invention is shown in these figures.
- the outer wall-reinforced areas 7 and the inner wall-reinforced areas 8 are designed such that the ribs are equipped with wall reinforcements over approximately their entire height. Areas 9 and 9 'may not be wall reinforced depending on the embodiment of the invention. This configuration ensures that the boxes can also be packed sufficiently tightly in the empty stacked position, so that no unnecessary stacking space is required.
- This almost complete design of the ribs with wall-reinforced areas ensures that the stacking crates are able to withstand very high pressures, and in particular even at high stacking heights it is guaranteed that the stacking will not become unstable.
- the described embodiment of the invention can be modified in many ways without departing from the basic idea.
- the height of the individual ribs over which the wall-reinforced regions extend is not specified. It is also conceivable that not all ribs are provided with wall-reinforced areas in the same way, and that the reinforcement areas are formed as ribbed surfaces, whereby the stability of the ribs can be increased.

Abstract
Description
Die Erfindung betrifft einen wandverstärorben konischen Stapelkasten wie er im Oberlsegnitt der Anspruchs beschrieben wird.The invention relates to a wall-reinforced conical stacking box as described in the top section of the claim.
Es gibt eine Vielzahl von Einsatzmöglichkeiten für Stapelkästen, die im gefüllten Zustand von einem Ort zu einem anderen transportiert, dort entleert, und im leeren Zustand zum Füllort zurückgebracht werden müssen. Hier seien beispielsweise Behälter für lebende Pflanzen und dgl. genannt. Die Pflanzen werden in Treibhäusern in die Stapelkästen eingesetzt, dann auf Beförderungsmittel verladen, wobei die Kästen übereinander gestapelt sind, ohne das im darunter liegenden Kasten befindliche Gut, wie z.B. die lebenden Pflanzen, zu zerstören. Auf dem Rücktransport der leeren Kästen ist eine solche Stapelung unwirtschaftlich, deshalb sind die Kästen so ausgerüstet, daß sie ineinander gestapelt werden können und so weniger Stauraum einnehmen.There are a multitude of possible uses for stacking crates which, when filled, are transported from one place to another, emptied there, and have to be returned to the filling location when empty. Containers for living plants and the like may be mentioned here, for example. The plants are inserted into the stacking boxes in greenhouses, then loaded onto means of transport, the boxes being stacked one on top of the other without destroying the goods in the box below, such as the living plants. Such a stacking is uneconomical on the return transport of the empty boxes, so the boxes are equipped in such a way that they can be stacked one inside the other and thus take up less storage space.
Eine bekannte Lösung besteht darin, den Stapelkasten asymmetrisch an den Stirnseiten mit einem Vorsprung bzw. einem nach außen ragenden Rücksprung auszurüsten, derart, daß in der einen Lage alle Kästen ineinander passen, d.h. die Vorsprünge der einen Seite korrespondieren direkt mit den Vorsprüngen des nächsten Kastens und sofort. Werden nun derartige Kästen in wechselnder Folge in der Horizontalebene um 180° gedreht aufeinander gestapelt, so trifft der eine Rücksprung im beispielsweise oberen Kasten auf den Vorsprung im unteren Kasten, so daß ein Ineinandersinken der beiden deckellosen Kästen unmöglich ist. Diese Lösung hat sich aber in der Praxis als verbesserungswürdig herausgestellt, da durch die lediglich zweiseitige Aufnahme der gefüllten Kästen das von den unteren Kästen tragbare Gewicht begrenzt ist, so daß nur eine gewisse Stapelhöhe erreicht werden kann.A known solution consists in equipping the stacking box asymmetrically at the end faces with a projection or an outwardly projecting recess, such that in one position all boxes fit into one another, i.e. the projections on one side correspond directly with the projections on the next box and immediately. If such boxes are now stacked on top of one another in an alternating sequence in the horizontal plane rotated by 180 °, a recess in the upper box, for example, meets the projection in the lower box, so that the two lidless boxes cannot sink into one another. In practice, however, this solution has proven to be in need of improvement, since the weight that can be carried by the lower boxes is limited by the fact that the filled boxes can only be received on two sides, so that only a certain stack height can be achieved.
Eine bessere Lösung liegt darin, konische Stapelkästen zu verwenden, die Vor- bzw. Rücksprünge an allen Kastenwänden aufweisen, welche als nach außen weisende, über die gesamte Kastenhöhe angeordnete, zum Kasteninneren hin offene Rippen ausgebildet sind (DE-U- 86 27 458 des Anmelders). Diese nicht symmetrisch am Umfang der Kästen angebrachten Rippen ermöglichen eine homogenere Kraftverteilung in den Kästen und damit höhere Druckbeanspruchung.A better solution is to use conical stacking boxes which have projections or recesses on all box walls, which are designed as outwardly pointing ribs which are arranged over the entire box height and are open towards the inside of the box (DE-U-86 27 458 des Applicant). These ribs, which are not symmetrically attached to the circumference of the boxes, enable a more homogeneous distribution of force in the boxes and thus higher pressure loads.
In der Praxis hat sich aber gezeigt, daß auch die Belastbarkeit solcher konischer Stapelkästen begrenzt ist. Ab einer gewissen Stapelhöhe kann der Druck auf die unteren Kästen derart zunehmen, daß die Gefahr besteht, daß sich die Wandflächen dieser Kästen zu verformen beginnen und die gesamte Stapelung instabil wird.In practice it has been shown that the load capacity of such conical stacking boxes is also limited. Above a certain stack height, the pressure on the lower boxes can increase in such a way that there is a risk that the wall surfaces of these boxes begin to deform and the entire stacking becomes unstable.
Aufgabe der Erfindung ist deshalb die Schaffung einer Lösung, mit der derartige Stapelkästen einer höheren Druckbeanspruchung ausgesetzt werden können, wobei geringe Wandstärken der Kastenwände möglichst beibehalten werden können.The object of the invention is therefore to provide a solution with which such stacking boxes can be subjected to a higher pressure load, wherein the wall thicknesses of the box walls can be kept as small as possible.
Bei einem Stapelkasten der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruches gelöst.In a stacking box of the type described in the introduction, this object is achieved according to the invention by the characterizing features of the claim.
Die verstärkten Wandbereiche der am Umfang verteilten Rippen ermöglichen eine hohe Druckbeanspruchung der einzelnen Rippe und damit des gesamten Stapelkastens, so daß eine hohe Stapelhöhe erreichbar ist. Außerdem ist eine Verringerung der notwendigen Rippenanzahl und der Wandstärken der zwischen den Rippen gelegenen Flächen des Kastens möglich.The reinforced wall areas of the ribs distributed around the circumference enable the individual rib and thus the entire stacking box to be subjected to high pressure, so that a high stacking height can be achieved. It is also possible to reduce the number of ribs required and the wall thicknesses of the areas of the box located between the ribs.
Dadurch, daß die Rippen verstärkte Wandbereiche in etwa umschlagsymmetrischer Gestaltung innen unten und außen oben aufweisen, werden keine Stützstege mehr benötigt, wie sie bei dem gattungsbildenden Gebrauchsmuster DE-86 27 458-U des Anmelders vorbeschrieben sind. Der Sprungversatz der verstärkten Wandbereiche gewährleistet, daß beim Ineinanderstapeln im Leerzustand die Zwischenräume zwischen den gestapelten Kästen ausreichend gering verbleiben, wobei damit auch gewährleistet ist, daß durch die größere Materialdicke der Wandbereiche der Rippen eine besonders hohe Stabilität und Druckbelastbarkeit der Stapelkästen erreicht wird.The fact that the ribs reinforced wall areas in approximately envelope-symmetrical design inside below and outside above have, no support webs are required, as described in the generic utility model DE-86 27 458-U of the applicant. The jump offset of the reinforced wall areas ensures that the interstices between the stacked boxes remain sufficiently small when stacked one inside the other, whereby this also ensures that a particularly high stability and compressive strength of the stacking boxes is achieved due to the greater material thickness of the wall areas of the ribs.
Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert, diese zeigt in
- Fig. 1 mit wandverstärkten Bereichen versehene Rippen in der Leerstapellage,
- Fig. 2 die gleichen Kästen in der Vollstapellage in gleicher Darstellungsart, wie in Fig. 1,
- Fig. 3 einen Schnitt gemäß der Linie I-I in Fig. 1 und in
- Fig. 4 einen Schnitt gemäß der Linie II-II in Fig. 2.
- 1 ribs provided with wall-reinforced areas in the empty stack position,
- 2 shows the same boxes in the full stack position in the same representation as in FIG. 1,
- Fig. 3 shows a section along the line II in Fig. 1 and in
- 4 shows a section along the line II-II in FIG. 2.
In den Figuren sind zwei Stapelkästen 1 und 1′ dargestellt, wobei der obere Stapelkasten das Bezugszeichen 1′ trägt, während der untere Stapelkasten mit 1 bezeichnet ist.In the figures, two
In den Figuren 1 und 2 sind die Stapelkästen in Leer- bzw. Vollstapellage dargestellt. Jeder Stapelkasten weist zwei Längsseiten 2 bzw. 2′ und zwei Stirnseiten 3 bzw. 3′ sowie einen Kastenboden 4 bzw. 4′ und eine Kastenöffnung 5 bzw. 5′ auf. Beide Seiten 2 und 3 mit Rippen 6 bzw. 6′ ausgerüstet, die asymmetrisch am Umfang verteilt sind. Diese Rippen weisen am oberen Teil der Außenflächen äußere wandverstärkte Bereiche 7 bzw. 7′ und am unteren Teil, der in Fig. 1 und 2 zwar nicht, aber in Fig. 3 und 4 dargestellten Innenflächen innere wandverstärkte Bereiche 8 bzw. 8′ auf. Aufgrund der Asymmetrischen Anordnung der Rippen 6 passen die beiden Stapelkästen 1 und 1′ je nach Lage der Rippen der beiden Kästen zueinander ineinander oder nicht, d.h. es entsteht eine Leer- oder Vollstapelung.In Figures 1 and 2, the stacking boxes are shown in empty or full stack position. Each stacking box has two
In den Fig. 3 und 4 sind zwei Schnitte gemäß der Linien I-I in Fig. 1 und II-II in Fig. 2 dargestellt. In diesen Figuren ist eine mögliche Ausgestaltung der Erfindung gezeigt. Die äußeren wandverstärkten Bereiche 7 und die inneren wandverstärkten Bereiche 8 sind derart gestaltet, daß die Rippen etwa über ihre gesamte Höhe mit Wandverstärkungen ausgerüstet sind. Bereiche 9 bzw. 9′ können je nach Ausgestaltung der Erfindung nicht wandverstärkt sein. Diese Ausgestaltung gewährleistet, daß die Kästen auch in der Leerstapellage ausreichend dicht gepackt werden können, also kein unnötiger Stapelraum benötigt wird. Durch diese fast vollständige Ausgestaltung der Rippen mit wandverstärkten Bereichen wird eine sehr hohe Druckbelastbarkeit der Stapelkästen gewährleistet, insbesondere ist auch bei hohen Stapelhöhen garantiert, daß die Stapelung nicht instabil wird.3 and 4, two sections along the lines I-I in Fig. 1 and II-II in Fig. 2 are shown. A possible embodiment of the invention is shown in these figures. The outer wall-reinforced
Natürlich ist das beschriebene Ausführungsbeispiel der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So ist insbesondere nicht festgelegt, über welche Höhe der einzelnen Rippen sich die wandverstärkten Bereiche erstrecken. Außerdem ist vorstellbar, daß nicht alle Rippen in gleicher Weise mit wandverstärkten Bereichen versehen sind, und daß die Verstärkungs- bereiche als gerippte Flächen ausgebildet sind, wodurch die Stabilität der Rippen noch vergrößert werden kann.Of course, the described embodiment of the invention can be modified in many ways without departing from the basic idea. In particular, the height of the individual ribs over which the wall-reinforced regions extend is not specified. It is also conceivable that not all ribs are provided with wall-reinforced areas in the same way, and that the reinforcement areas are formed as ribbed surfaces, whereby the stability of the ribs can be increased.
