Description

Die Erfindung betrifft einen Behälter für Transport und Lagerung von Gütern mit einem Behälterboden und zumindest zwei übereinander klappbaren Seitenwänden gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a container for transport and storage of goods with a container bottom and at least two superposed side walls according to the preamble of claim 1.

Leere Behälter oder Kästen mit fest ausgebildeten Seitenwänden nehmen viel Stauraum ein. Daher sind Behälter bekannt, die klappbare Seitenwände aufweisen, um das Leertransportvolumen entsprechend zu verkleinern.Empty containers or boxes with fixed side walls take up a lot of storage space. Therefore, containers are known which have hinged side walls to reduce the empty transport volume accordingly.

Derartige Klappbehäiter weisen zumeist einen Behälterboden mit rechteckförmigem Grundriss auf, an dessen Rändern die klappbaren Seitenwände mittels Scharnieren angelenkt sind.Such Klappbehäiter usually have a container bottom with a rectangular plan, at the edges of the hinged side walls are hinged by means of hinges.

In aufgeklappter Stellung der Seitenwände erfolgt ein Rastverbund der Seitenwände untereinander, wobei üblicherweise entsprechende Rastriegel an einem Paar gegenüberliegend angeordneter Seitenwände hinter entsprechenden Rasthaken am anderen Paar der gegenüberliegend angeordneten Seitenwände eingreifen.In the unfolded position of the side walls, a latching connection of the side walls takes place with one another, with corresponding latching bars usually engaging on a pair of oppositely disposed side walls behind corresponding latching hooks on the other pair of oppositely disposed side walls.

Bei vielen Behältern sind die Seitenwände höher als die halbe Breite des Behälterbodens ausgebildet, so dass es, wenn zwei gegenüberliegend angeordnete Seitenwände aufeinander zugeklappt werden, zu einem Überlappen der Seitenwände kommt. Dabei steht die zuletzt umgeklappte Seitenwand schräg über die stirnseitige äußere Kante der zuerst umgeklappten Seitenwand hinweg und kommt nicht parallel zum Behälterboden, sondern in einem Winkel dazu, d. h. in einer Schrägstellung zum liegen. Werden mehrere Behälter aufeinander gestapelt, so ergibt sich ein entsprechendes Biegemoment auf die schräg liegende obere Seitenwand, was auf Dauer die Gefahr einer Deformation oder Schädigung mit sich bringt. Bei derartigen Behältern ergibt sich auaußerdem der Nachteil, dass mehrere zusammengeklappte Behälter unter Umständen nicht stabil übereinander gestapelt werden können.In many containers, the side walls are formed higher than half the width of the container bottom, so that when two oppositely disposed side walls are folded toward each other, it comes to an overlap of the side walls. In this case, the last folded-over side wall is obliquely over the frontal outer edge of the first folded side wall away and does not come parallel to the container bottom, but at an angle to it, ie in an inclined position to lie. If several containers are stacked on top of each other, a corresponding bending moment results on the inclined upper side wall, which brings with it the risk of deformation or damage over time. In such containers results auausßerdem the disadvantage that several collapsed containers can not be stably stacked under certain circumstances.

Um die Nachteile zu vermeiden ist bekannt, die Seitenwände an unterschiedlich hoch ausgelegte Randleisten des Bodens anzulenken, so dass die Seitenwände entsprechend unterschiedlich hoch angelenkt sind, wobei zunächst die weniger hoch angelehnte Seitenwand und daraufhin die höher angelenkte Seitenwand umgeklappt wird, wodurch in Klappstellung beide Seitenwände plan zum Boden ausgerichtet sind.In order to avoid the disadvantages, it is known to articulate the side walls at different height designed edge strips of the soil, so that the side walls are hinged according to different heights, initially the less highly ajar side wall and then the higher hinged side wall is folded, whereby in the folded position both side walls plan are aligned to the ground.

Um ein Umbiegen einer oberen klappbaren Seitenwand, die auf einer unteren klappbaren Seitenwand aufliegt, zu verhindern, ist es bekannt, Scharnierbolzenaufnahmen mit Aussparungen vorzusehen, bei denen die Scharnierbolzen vertikal verschieblich von einer unteren in eine obere Endlage überführbar sind ( AU-B-45117/85 ) und US,6,460,717 B1 .In order to prevent bending of an upper foldable side wall, which rests on a lower foldable side wall, it is known to provide hinge pin receptacles with recesses in which the hinge pins are vertically displaceable from a lower to an upper end position ( AU-B-45117/85 ) and US, 6,460,717 B1 ,

Der Erfindung liegt die Aufgabe zugrunde, einen einfach aufgebauten und robusten Klappmechanismus für einen Behälter mit klappbaren Seitenwänden zu schaffen, der ein planes Aufeinanderliegen zweier eingeklappter Seitenwände ermöglicht.The invention has for its object to provide a simply constructed and robust folding mechanism for a container with hinged side walls, which allows a flat superimposition of two collapsed side walls.

Die Aufgabe wird erfindungsgemäß gelöst durch die Merkmale im kennzeichnenden Teil des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale der Unteransprüche gekennzeichnet.The object is achieved by the features in the characterizing part of claim 1. Advantageous developments of the invention are characterized by the features of the subclaims.

Dabei ist vorgesehen, dass die übereinander klappbaren Seitenwände durch Scharniere an dem Behälterboden angelenkt sind, wobei die Scharniere mit Scharnierbolzen in Scharnierbolzenaufnahmen gelenkig gelagert sind und die Scharnierbolzenaufnahmen Aussparungen aufweisen, die derart ausgebildet sind, dass die Scharnierbolzen in den Scharnierbolzenaufnahmen aus einer unteren Endlage, in welcher die umgeklappte Seitenwand auf dem Behälterboden aufliegt, so weit in eine obere Endlage bewegbar sind, dass ein planes Aufeinanderliegen zweier Seitenwände möglich ist.It is provided that the superimposed hinged side walls are hinged by hinges on the container bottom, the hinges are hingedly mounted with hinge pin in hinge pin receptacles and the hinge pin receptacles have recesses formed such that the hinge pin in the hinge pin receptacles from a lower end position, in which rests the folded side wall on the container bottom, as far as are movable into an upper end position, that a flat superimposition of two side walls is possible.

Insbesondere weisen die Aussparungen obere Bereiche mit ersten Breiten und untere Bereiche mit zweiten Breiten auf, wobei die ersten Breiten kleiner als die zweiten Breiten sind. Dabei sind die Scharnierbolzen in den unteren Endlagen in den unteren Bereichen der Aussparungen angeordnet und in den oberen Endlagen in den oberen Bereichen der Aussparungen angeordnet.In particular, the recesses have upper portions with first widths and lower portions with second widths, wherein the first widths are smaller than the second widths. The hinge pins are arranged in the lower end positions in the lower regions of the recesses and arranged in the upper end positions in the upper regions of the recesses.

Derartig angelenkte übereinander klappbare Seitenwände können in beliebiger Reihenfolge umgeklappt werden und kommen plan aufeinander zum liegen. Der Benutzer braucht sich keine Gedanken mehr machen, welche Seitenwand zuerst zugeklappt werden muss.Such hinged superimposed side walls can be folded in any order and come flat on each other to lie. The user no longer has to worry about which side wall has to be collapsed first.

In einer bevorzugten Ausführungsform weisen die Aussparungen senkrecht zum Behälterboden Längen auf, die größer als die Dicke der Seitenwand, vorzugsweise etwa zwischen der einfachen und der zweifachen Dicke der Seitenwand, ausgebildet sind. Dadurch sind die Scharnierbolzen in den Scharnierbolzenaufnahmen über die so bestimmten Längen bewegbar gelagert.In a preferred embodiment, the recesses have perpendicular to the container bottom lengths which are greater than the thickness of the side wall, preferably formed approximately between the single and the double thickness of the side wall. As a result, the hinge pins are movably mounted in the hinge pin receptacles over the lengths determined in this way.

In einer bevorzugten Ausführungsform sind die Scharnierbolzenaufnahmen aus den Aussparungen und einer, vorzugsweise einstückig mit dem Behälterboden ausgebildeten, seitlich angeformten Randleiste mit einer Außenwand und einer Innenwand gebildet. Die einstückig mit dem Behälterboden ausgebildete Randleiste kann kostengünstig und Material sparend im Spritzgussverfahren zusammen mit dem Behälterboden hergestellt werden.In a preferred embodiment, the hinge pin receptacles of the recesses and a, preferably integrally formed with the container bottom, laterally molded edge strip with an outer wall and an inner wall are formed. The edge strip formed in one piece with the container bottom can be produced inexpensively and in a material-saving manner by injection molding together with the container bottom.

Bevorzugt ist die Randleiste bei einem Paar gegenüberliegend angeordneter Seitenwände höher ausgebildet als bei dem anderen Paar gegenüberliegender Seitenwände, so dass ein Paar gegenüberliegender Seitenwände bezüglich dem anderen Paar vertikal nach oben versetzt an den Behälterboden angelenkt ist. Dadurch kann eine Reihenfolge vorgegeben werden, welches Paar gegenüberliegende Seitenwände zuerst und welches zuletzt einzuklappen ist, beispielsweise die kürzeren Seitenwände zuerst und die längeren Seitenwände darüber. Das Paar zuerst eingeklappter Seitenwände weist das erfindungsgemäße Scharnier auf, bedarfsweise kann das erfindungsgemäße Scharnier auch an dem Paar zuletzt eingeklappter Seitenwände vorgesehen sein.Preferably, the skirt is formed higher in a pair of oppositely disposed sidewalls than in the other pair of opposed sidewalls, such that a pair of opposed sidewalls are hinged vertically upwardly of the container bottom with respect to the other pair. Thereby, an order can be given which pair of opposite side walls should be folded first and which one last, for example the shorter side walls first and the longer side walls above. The pair of first folded-in side walls has the hinge according to the invention, if necessary, the hinge according to the invention can also be provided on the pair of last-folded side walls.

Bevorzugt weisen die Scharnierbolzen Nasen auf, die bei umgeklappter Seitenwand vertikal nach unten weisen. Die Scharnierbolzen weisen bei umgeklappter Seitenwand horizontale Erstreckungen und vertikale Erstreckungen auf, wobei die Größe der vertikalen Erstreckungen die Länge der Nasen mit einschließt. Die horizontalen Erstreckungen sind dabei kleiner als die vertikalen Erstreckungen.The hinge pins preferably have lugs which point vertically downwards when the side wall is folded over. When the side wall is folded down, the hinge pins have horizontal extensions and vertical extensions, the size of which being vertical Distances include the length of the noses. The horizontal extents are smaller than the vertical extents.

Dabei ist es von Vorteil, wenn die Aussparungen obere Bereiche mit ersten Breiten und untere Bereiche mit zweiten Breiten aufweisen, wobei die ersten Breiten zur Aufnahme der Scharnierbolzen bei umgeklappter Seitenwand in etwa in der Größe der horizontalen Scharnierbolzenerstreckungen ausgebildet sind und die zweiten Breiten zur Aufnahme der Scharnierbolzen bei umgeklappter und aufgestellter Seitenwand in etwa in der Größe der vertikalen Scharnierbolzenerstreckungen ausgebildet sind. Dadurch wird erreicht, dass sich die Seitenwand in aufgeklappter Stellung stets im unteren Bereich der Aussparung befindet, da sie in aufgeklappter Stellung nicht in den oberen Bereich der Aussparung passt.It is advantageous if the recesses have upper portions with first widths and lower portions with second widths, wherein the first widths for receiving the hinge pin with the side wall folded down are formed approximately in the size of the horizontal hinge pin extensions and the second widths for receiving the Hinge bolts are formed with the folded and erected side wall in approximately the size of the vertical hinge pin extensions. This ensures that the side wall in the unfolded position is always in the lower region of the recess, since it does not fit in the unfolded position in the upper region of the recess.

In einer weiteren Ausführungsform der Erfindung verbleiben in aufgeklappter Stellung der Seitenwand zwischen den Scharnierbolzen mit ihren Nasen und der Innenwand der Randleiste und/oder zwischen den Scharnierbolzen mit ihren Nasen und der Außenwand der Randleiste kleine Spalte von vorzugsweise etwa zwei bis drei Zehnteln der Breiten der unteren Bereiche der Aussparungen. Damit ist ein Spiel der Seitenwand im Bereich der Scharnierbolzen vorgesehen, was sowohl das Auf- und Zuklappen erleichtert als auch die verletzbaren Scharnierbolzen vor mechanischer Beanspruchung bei aufgestellter Seitenwand schützt.In a further embodiment of the invention remain in the unfolded position of the side wall between the hinge pin with its lugs and the inner wall of the skirt and / or between the hinge pin with their noses and the outer wall of the skirt small column of preferably about two to three tenths of the widths of the lower Areas of recesses. Thus, a game of the side wall is provided in the hinge bolts, which facilitates both the opening and closing and protects the vulnerable hinge pin against mechanical stress when erected side wall.

Zur horizontalen Positionierung der Seitenwand in aufgeklappter Stellung sind bevorzugt an der Innenwand der Randleiste Anschläge und an dem unteren Ende der Seitenwand nach unten gerichtete Vorsprünge ausgebildet, wobei in aufgestellter Lage der Seitenwand die nach unten gerichteten Vorsprünge an die Anschläge anschlagen. Dadurch wird insbesondere die stirnseitige Verrastung mit den anliegenden Seitenwänden erleichtert, da die Seitenwand in eine feste Position gestellt ist.For horizontal positioning of the side wall in the unfolded position stops are preferably formed on the inner wall of the edge strip stops and at the lower end of the side wall downwardly directed projections, wherein in an erected position of the side wall, the downwardly directed projections abut against the stops. As a result, in particular the frontal locking is made easier with the adjacent side walls, since the side wall is placed in a fixed position.

In einer vorteilhaften Weiterbildung weist die Seitenwand an ihrem unteren Ende nach außen gerichtete Nasen auf, die in aufgestellter Lage der Seitenwand an die Außenwand der Randleiste anschlagen. Der Anschlag der nach außen gerichteten Nasen der Seitenwand an der Randleiste erweist sich ebenfalls insbesondere als vorteilhaft für die Durchführung der stirnseitigen Verrastung der Seitenwand mit den anliegenden Seitenwänden, da die Seitenwand horizontal fest positioniert wird.In an advantageous development, the side wall has at its lower end outwardly directed lugs, which in an erected position of the side wall to the outer wall hit the sidebar. The stop of the outwardly directed lugs of the side wall on the edge strip also proves to be particularly advantageous for carrying out the frontal locking of the side wall with the adjacent side walls, since the side wall is positioned horizontally fixed.

Zur vertikalen Positionierung der Seitenwand in aufgeklappter Stellung sind bevorzugt an der Randleiste im oberen Bereich an der Innenseite der Außenwand nach innen gerichtete Nasen ausgebildet, und in Höhe der nach innen gerichteten Nasen an der Außenfläche der Seitenwand Aussparungen ausgebildet, wobei in aufgestellter Lage der Seitenwand die nach innen gerichteten Nasen in die Aussparungen eingeführt sind. Die nach innen gerichteten Nasen der Seitenwand und die Aussparungen an der Randleiste fixieren die Seitenwand in aufgeklappter Stellung in ihrer Höhe, was den Kasten für den Benutzer handhabbarer macht, da der Behälterboden und die Seitenwand relativ zueinander weniger Spiel aufweisen.For vertical positioning of the side wall in the unfolded position are preferably formed on the edge strip in the upper region on the inside of the outer wall inwardly directed lugs, and formed at the level of inwardly directed lugs on the outer surface of the side wall recesses, wherein in an upright position of the side wall inwardly directed lugs are inserted into the recesses. The inwardly directed lobes of the side wall and the recesses on the edge strip fix the side wall in the unfolded position in height, which makes the box easier to handle for the user, since the container bottom and the side wall have less play relative to each other.

In bevorzugten Ausführungsformen ist die Seitenwand mittels zumindest zwei, bevorzugt drei bis vier erfindungsgemäßer Scharnieren an dem Behälterboden angelenkt.In preferred embodiments, the side wall is hinged to the container bottom by means of at least two, preferably three to four hinges according to the invention.

In der nachfolgenden Figurenbeschreibung werden weitere bevorzugte Ausführungsformen der Erfindung angegeben.In the following description of the figures further preferred embodiments of the invention are given.

Figur 1 zeigt eine Schnittansicht eines Behälters 100 aus dem Stand der Technik, der vier Seitenwände und einen Behälterboden 102 aufweist. Dargestellt sind zwei einander gegenüberliegende Seitenwände 101 und 101a, die über Scharniere 103 und 103a an den Behälterboden 102 gekoppelt sind. Die Scharniere 103 und 103a sind im Bereich einer an den Behälterboden 102 angeformten Randleiste 105 angeordnet. Die Randleiste 105 steht nach oben, d. h. senkrecht zu einer Ebene durch den Behälterboden 102 über den Behälterboden 102 hervor. Die Seitenwand 101 ist umgeklappt und liegt dabei horizontal und plan auf dem Behälterboden 102 auf. Die Seitenwand 101a ist ebenfalls umgeklappt und kommt, da sich die beiden Seitenwände 101 und 101a in einem mittleren Bereich M des Behälterbodens 102 überlappen, auf einer stirnseitigen Kante 104 der Seitenwand 101 zum liegen. Die Seitenwände 101 und 101a überlappen sich zwar, liegen aber nicht plan aufeinander sondern es steht die zuletzt umgeklappte Seitenwand 101a im Überlappungsbereich M mit einem sich vergrößerndem Spalt 106 schräg über die zuerst umgeklappte Seitenwand 101 vor. FIG. 1 shows a sectional view of a container 100 of the prior art, which has four side walls and a container bottom 102. Shown are two opposing side walls 101 and 101 a, which are coupled via hinges 103 and 103 a to the container bottom 102. The hinges 103 and 103a are arranged in the region of a skirt 105 formed on the container bottom 102. The skirt 105 is up, ie perpendicular to a plane through the container bottom 102 on the container bottom 102 out. The side wall 101 is folded down and lies horizontally and flat on the container bottom 102. The side wall 101a is also folded over and, since the two side walls 101 and 101a overlap in a middle region M of the container bottom 102, comes to lie on an end edge 104 of the side wall 101. Although the side walls 101 and 101a overlap, they are not flat on one another but the last folded-over side wall 101a projects in the overlapping area M with a widening gap 106 obliquely over the first folded-over side wall 101.

Bei einer Stapelung eines weiteren Behälters auf den Behälter 100 ergibt sich ein Biege- oder Drehmoment auf die zuletzt umgeklappte Seitenwand 101a um die Kante 104 als Biege- oder Drehachse, da der Boden des oberen Behälters auf die schräg liegende Seitenwand 101a aufliegt und diese nach unten drückt.When another container is stacked on the container 100, a bending or torque results on the last folded-over side wall 101a around the edge 104 as a bending or rotation axis, since the bottom of the upper container rests on the inclined side wall 101a and pushes them down.

Figur 2 zeigt einen Teil eines erfindungsgemäßen Behälterbodens 2 und einer umgeklappten Seitenwand 1 in Schnittansicht entlang eines Schnitts X-X gemäß Figur 8. Die Schnittebene der Figuren 2 bis 4 und 7 geht durch die Linie X-X und die Schnittebene der Figuren 5 und 6 geht durch die Linie Z-Z. FIG. 2 shows a part of a container bottom according to the invention 2 and a folded side wall 1 in a sectional view along a section XX according to FIG. 8 , The cutting plane of the FIGS. 2 to 4 and 7 goes through the line XX and the cutting plane of the Figures 5 and 6 goes through the line ZZ.

Die Seitenwand 1 ist mittels eines Scharniers 3 an dem Behälterboden 2 angelenkt. Das Scharnier 3 weist hier rein beispielshalber einen Scharnierbolzen 4 und eine Scharnierbolzenaufnahme 5 auf. Der Scharnierbolzen 4 ist nach Art eines üblichen Scharnierbestandteils ausgebildet. In den Figuren 8 bis 11 sind dazu Ausführungsbeispiele dargestellt.The side wall 1 is articulated by means of a hinge 3 to the container bottom 2. The hinge 3 has here purely by way of example a hinge pin 4 and a hinge pin receptacle 5. The hinge pin 4 is formed in the manner of a conventional hinge component. In the FIGS. 8 to 11 For this purpose, exemplary embodiments are shown.

Figur 2 zeigt weiterhin eine Nase 6, die als Fortsatz des Scharnierbolzens 4 ausgebildet und vertikal nach unten gerichtet ist. Der Scharnierbolzen 4 weist bei umgeklappter Seitenwand 1 eine horizontale Erstreckung der Größe D1 (vgl. Fig. 3) und eine vertikale Erstreckung der Größe D2 auf, wobei die Größe D2 der vertikalen Scharnierbolzenerstreckung die Länge der Nase 6 mit einschließt und größer als D1 ist. FIG. 2 further shows a nose 6, which is formed as an extension of the hinge pin 4 and directed vertically downwards. When the side wall 1 is folded over, the hinge pin 4 has a horizontal extension of the size D 1 (cf. Fig. 3 ) and a vertical extent of size D 2 , wherein the size D 2 of the vertical hinge pin extension includes the length of the nose 6 and is greater than D 1 .

Die Scharnierbolzenaufnahme 5 ist kastenförmig und wird von einer Randleiste 7 und einer Aussparung 8 gebildet. Die Randleiste 7 ist einstückig mit dem Behälterboden 2 ausgebildet und ist seitlich an den Behälterboden 2 vollumfänglich angeformt. Sie umgibt die Aussparung 8, die einen Käfig mit einem horizontalen Spielraum und einem vertikalen Spielraum für den Scharnierbolzen 4 bildet. Die Randleiste 7 ist unterseitig offen etwa nach Art eines umgekehrten "U" ausgebildet, wobei die Schenkel des "U" eine Außenwand 9 und eine Innenwand 10 der Randleiste 7 bilden. In weiteren Ausführungsformen kann die Randleiste 7 unterseitig geschlossen ausgebildet sein und die Aussparung 8 im Sinne eines Rahmens vollständig umschließen.The hinge pin receptacle 5 is box-shaped and is formed by a skirt 7 and a recess 8. The edge strip 7 is formed integrally with the container bottom 2 and is integrally formed on the container bottom 2 to the full extent. It surrounds the recess 8, which forms a cage with a horizontal clearance and a vertical clearance for the hinge pin 4. The skirt 7 is open on the underside open in the manner of an inverted "U", wherein the legs of the "U" form an outer wall 9 and an inner wall 10 of the skirt 7. In further embodiments, the edge strip 7 may be formed closed on the underside and completely enclose the recess 8 in the sense of a frame.

Die Aussparung 8 hat vertikal, d. h. senkrecht zu einer durch den Behälterboden 2 definierten Ebene, eine Länge L. Dargestellt ist weiterhin die maximale Dicke D der Seitenwand 2. Die Aussparung 8 ist in ihrer Länge L größer als die einfache Dicke D der Seitenwand 1, etwa zwischen einfacher und zweifacher Dicke D der Seitenwand ausgebildet.The recess 8 has vertical, d. H. Also shown is the maximum thickness D of the side wall 2. The recess 8 is greater in its length L than the simple thickness D of the side wall 1, approximately between single and double thickness D. formed the side wall.

Die Aussparung 8 ist in einen oberen Bereich 11 mit einer in der dargestellten Schnittebene definierten horizontalen Ausdehnung oder ersten Breite B1 und einen unteren Bereich 12 mit einer zweiten Breite B2 aufgeteilt, d. h. sie weist diese Bereiche auf, die einen horizontalen Spielraum für den Scharnierbolzen 4 und damit für die horizontale Lage der Seitenwand 1 definieren. Der obere Bereich 11 hat eine Breite B1, welche kleiner als die Breite B2 ist. Die Breite B1 ist zur Aufnahme des Scharnierbolzens 4 in etwa auf die Größe D1 der horizontalen Scharnierbolzenerstreckung ausgelegt. Der untere Bereich 12 weist eine Breite B2 von in etwa der Größe D2 der vertikalen Scharnierbolzenerstreckung auf.The recess 8 is divided into an upper region 11 with a horizontal extent or first width B 1 defined in the illustrated sectional plane and a lower region 12 with a second width B 2 , ie it has these areas which provide a horizontal clearance for the hinge pin 4 and thus define the horizontal position of the side wall 1. The upper portion 11 has a width B 1 which is smaller than the width B 2 . The width B 1 is designed to accommodate the hinge pin 4 in about the size D 1 of the horizontal hinge pin extension. The lower region 12 has a width B 2 of approximately the size D 2 of the vertical hinge pin extension.

In Figur 2 ist die Seitenwand 1 umgeklappt und liegt satt auf dem Behälterboden 2 auf. Die Lage der Seitenwand 1 zum Behälterboden 2 entspricht derjenigen der Seitenwand 101 aus Figur 1. Dies wird als untere Endlage der Seitenwand 1 zu dem Behälterboden 2 bezeichnet.In FIG. 2 If the side wall 1 is folded down and is fed on the container bottom 2. The position of the side wall 1 to the container bottom 2 corresponds to that of the side wall 101 FIG. 1 , This is referred to as the lower end position of the side wall 1 to the container bottom 2.

Figur 3 zeigt ebenfalls den Teil des Behälterbodens 2 und der umgeklappten Seitenwand 1 in Schnittansicht. Dargestellt ist darüber hinaus eine der Seitenwand 1 gegenüberliegend angeordnete Seitenwand 1a, welche umgeklappt ist. Zwischen einer Stirnseite 13 der umgeklappten Seitenwand 1a und einer Außenseite 14 der Innenwand 10 der Randleiste 7 verbleibt ein Spalt 15, da die Seitenwand 1a zwar höher als die halbe Breite des Behälterbodens 2 aber niedriger als die gesamte Breite des Behälterbodens 2 ausgebildet ist. FIG. 3 also shows the part of the container bottom 2 and the folded side wall 1 in a sectional view. Shown is also one of the side wall 1 opposite side wall 1a, which is folded. Between a front side 13 of the folded side wall 1a and an outer side 14 of the inner wall 10 of the skirt 7 remains a gap 15, since the side wall 1a is indeed formed higher than half the width of the container bottom 2 but lower than the entire width of the container bottom 2.

Die gegenüberliegende Seitenwand 1a ist als erstes umgeklappt, so dass sie unmittelbar, d.h. in der unteren Endlage auf dem Behälterboden 2 aufliegt. Die Seitenwand 1 ist aufgrund der erfindungsgemäßen Scharnierbolzenaufnahme 5 im Vergleich zur Anordnung in Figur 2 um die Seitenwanddicke D höher liegend angeordnet, d. h. senkrecht zum Behälterboden 2 um etwa die Seitenwanddicke D parallel nach oben versetzt und liegt ihrerseits plan auf der gegenüberliegenden Seitenwand 1a auf. Dies bezeichnet eine obere Endlage der Seitenwand 1 zum Behälterboden 2, wobei ersichtlich in Stapelstellung kein Drehmoment wegen des Überlappens der Seitenwände 2 im mittleren Bereich des Behälterbodens 2 und damit keine nachteilige Biegebeanspruchung auf die oben liegende umgeklappte Seitenwand 1 einwirkt.The opposite side wall 1a is folded down first, so that it rests directly, ie in the lower end position on the container bottom 2. The side wall 1 is due to the hinge pin receptacle 5 according to the invention compared to the arrangement in FIG. 2 arranged higher lying around the side wall thickness D, that is offset perpendicular to the container bottom 2 by about the side wall thickness D parallel upward and in turn is flat on the opposite side wall 1a. This denotes an upper end position of the side wall 1 to the container bottom 2, wherein apparent in the stacking position no torque because of the overlapping of the side walls 2 in the central region of the container bottom 2 and thus no adverse bending stress on the overhead folded side wall 1 acts.

Um dies zu erreichen ist die Aussparung 8 so hoch ausgebildet, dass der Scharnierbolzen 4 in der Aussparung 8 von der unteren Endlage zur oberen Endlage bewegbar ist. In der oberen Endlage ist der Scharnierbolzen 4 im oberen Bereich 11 der Aussparung 8 angeordnet. Dabei ist die Breite B1 der Aussparung 8 im oberen Bereich 11 etwa an die Größe D1 der horizontalen Scharnierbolzenerstreckung angepasst, so dass horizontal im Wesentlichen kein Spiel der Seitenwand 1 verbleibt. Die Nase 6 weist in der oberen Endlage der Seitenwand 1 nach unten.To achieve this, the recess 8 is formed so high that the hinge pin 4 is movable in the recess 8 from the lower end position to the upper end position. In the upper end position, the hinge pin 4 is arranged in the upper region 11 of the recess 8. In this case, the width B 1 of the recess 8 in the upper region 11 is approximately matched to the size D 1 of the horizontal hinge pin extension, so that substantially no play of the side wall 1 remains horizontally. The nose 6 points in the upper end position of the side wall 1 down.

Figur 4 zeigt die Seitenwand 1 in aufgeklappter Stellung zum Behälterboden 2. In aufgeklappter Stellung befindet sich der Scharnierbolzen 4 im unteren Bereich 12 der Scharnierbolzenaufnahme 5. Die Nase 6 weist in die Richtung der hier nicht dargestellten gegenüberliegenden Seitenwand 1a. Die Aussparung 8 ist derart ausgebildet, dass zwischen dem Scharnierbolzen 4 mit seiner Nase 6 und der Innenseite 16 der Innenwand 10 der Randleiste 7 ein Spalt 17 verbleibt. Der Spalt 17 beträgt etwa zwei bis drei Zehntel der Breite B2 des unteren Bereichs 12 der Aussparung 8. In einer weiteren Ausführungsform können der Scharnierbolzen 4 und die Nase 6 den unteren Bereich 12 der Aussparung 8 auch so ausfüllen, dass horizontal im Wesentlichen kein Spiel der Seitenwand 1 verbleibt. In noch weiteren Ausführungsformen kann auch zwischen dem Scharnierbolzen 4 und der Innenseite der Außenwand 19 der Randleiste 7 ein entsprechender Spalt verbleiben. FIG. 4 shows the side wall 1 in the unfolded position to the container bottom 2. In the unfolded position is the hinge pin 4 in the lower portion 12 of the hinge pin receptacle 5. The nose 6 points in the direction of the opposite side wall 1a, not shown here. The recess 8 is formed such that between the hinge pin 4 with its nose 6 and the inside 16 of the inner wall 10 of the skirt 7 a gap 17 remains. The gap 17 is about two to three tenths of the width B 2 of the lower portion 12 of the recess 8. In another embodiment, the hinge pin 4 and the nose 6, the lower portion 12 of the recess 8 also fill so that horizontally substantially no play the side wall 1 remains. In still further embodiments, a corresponding gap may also remain between the hinge pin 4 and the inside of the outer wall 19 of the skirt 7.

Figur 5 zeigt eine weitere Schnittansicht eines Teils des Behälterbodens 2 und der Seitenwand 1 in aufgeklappter Stellung, wobei der Schnitt etwas versetzt gegenüber den in den Figuren 2 bis 4 dargestellten Schnitten liegt. Die Randleiste 7 ist in diesem Bereich aus der Innenwand 10 und der Außenwand 9 gebildet und ist nach oben und unten hin offen. An der Randleiste 7 ist im oberen Bereich an der Innenseite 19 der Auβenwand 9 eine nach innen gerichtete Nase 20 als Positionierelement ausgebildet. An der Innenwand 10 ist als weiteres Positionierelement ein Anschlag 21 ausgebildet. FIG. 5 shows a further sectional view of a portion of the container bottom 2 and the side wall 1 in the unfolded position, wherein the section slightly offset from the in the FIGS. 2 to 4 shown cuts lies. The edge strip 7 is formed in this area from the inner wall 10 and the outer wall 9 and is open at the top and bottom. On the edge strip 7, an inwardly directed nose 20 is formed as a positioning in the upper region on the inner side 19 of the outer wall 9. On the inner wall 10, a stop 21 is formed as a further positioning.

Die Seitenwand 1 weist in Höhe der nach innen gerichteten Nase 20 an ihrer Außenfläche eine Aussparung 22 auf. An der Seitenwand 1 sind am unteren Endabschnitt Positionierelemente in Form einer nach außen gerichteten Nase 23 und eines nach unten gerichteten Vorsprungs 24 ausgebildet.The side wall 1 has at the level of the inwardly directed nose 20 on its outer surface a recess 22. On the side wall 1 positioning elements in the form of an outwardly directed nose 23 and a downwardly directed projection 24 are formed at the lower end portion.

Durch diesen Aufbau wird ein Verspannmechanismus des Scharniers 3 gebildet. Um die Seitenwand 1 vertikal festzulegen, ist die nach innen gerichtete Nase 20 in aufgestellter Lage der Seitenwand 1 in die Aussparung 22 eingeführt. Damit die Seitenwand 1 in aufgestellter Lage horizontal festgelegt ist, schlagen der Vorsprung 24 gegen den Anschlag 21 an der Randleiste 7 und die nach außen gerichtete Nase 23 gegen einen unteren Teil der Innenseite 19 der Außenwand 9 der Randleiste 7 an.By this structure, a Verspannmechanismus the hinge 3 is formed. In order to fix the side wall 1 vertically, the inwardly directed nose 20 is inserted in an erected position of the side wall 1 in the recess 22. So that the side wall 1 is fixed horizontally in the raised position, the projection 24 abuts against the stop 21 on the edge strip 7 and the outwardly directed nose 23 against a lower part of the inner side 19 of the outer wall 9 of the skirt 7.

Der Verspannmechanismus zur Stabilisierung der Seitenwand 1 in aufgestellter Lage ist auf Höhe des flächig ausgebildeten Scharnierelements entlang der Linie Z - Z vorgesehen (vgl. Fig. 8). Daher können die Scharnierbolzen 4 mechanisch unbeansprucht sein, wenn die Seitenwand 1 aufgestellt ist, beispielsweise indem zwischen den Scharnierbolzen 4 und der Randleiste 7 Spiel vorgesehen ist.The bracing mechanism for stabilizing the side wall 1 in an upright position is provided at the height of the flat-shaped hinge element along the line Z - Z (cf. Fig. 8 ). Therefore, the hinge pins 4 may be mechanically unclaimed when the side wall 1 is erected, for example, by 7 game between the hinge pin 4 and the skirt.

In einer weiteren Ausführungsform kann die Seitenwand 1 anstelle der oder zusätzlich zu den der Aussparungen 22 nach außen gerichtete Nasen aufweisen, die mit Aussparungen zusammen wirken, die anstelle der oder zusätzlich zu den nach innen gerichteten Nasen 20 der Randleiste 7 ausgebildet sind.In a further embodiment, instead of or in addition to the recesses 22, the side wall 1 may have outwardly directed lugs which cooperate with recesses formed instead of or in addition to the inwardly directed lugs 20 of the skirt 7.

Figur 6 zeigt eine Zwischenstellung beim Auf- oder Zuklappen der Seitenwand 1 in der Schnittebene X-X. Dargestellt ist das Zusammenwirken der nach außen gerichteten Nase 23 mit der Innenseite 19 der Außenwand 9 der Randleiste 7. In umgeklappter Stellung der Seitenwand 1 zeigt die nach außen gerichtete Nase 23 nach oben. Wenn die Seitenwand 1 aufgeklappt wird, dann dreht sich die nach außen gerichtete Nase 23 infolge der Drehung der Seitenwand 1 um die Achse und berührt ab einem Moment die Innenseite 19 der Randleiste 7. Beim weiteren Aufklappen gleitet die Nase 23 an der Innenseite 19 der Randleiste 7 herab bis die Seitenwand 1 fest positioniert ist. FIG. 6 shows an intermediate position when opening or closing the side wall 1 in the sectional plane XX. Shown is the interaction of the outwardly directed nose 23 with the inside 19 of the outer wall 9 of the skirt 7. In the folded-down position of the side wall 1, the outwardly directed nose 23 points upwards. When the side wall 1 is opened, then the outwardly directed nose 23 rotates about the axis as a result of the rotation of the side wall 1 and touches the inner side 19 of the skirt 7 at a moment. As it unfolds, the nose 23 slides on the inside 19 of the skirt 7 down until the side wall 1 is firmly positioned.

Figur 7 zeigt eine Zwischenstellung beim Auf- oder Zuklappen der Seitenwand 1 in der Schnittebene entlang der Linie Z-Z. Wird die Seitenwand 1 ausgehend von der in Figur 3 dargestellten oberen Endlage aufgeklappt, dann trifft infolge der durch die Klappbewegung hervorgerufenen Drehung des Scharnierbolzens 4 die Nase 6 auf eine Innenseite 25 der Innenwand 10 der Randleiste 7. Dabei verlagert sich die Seitenwand 1 mittels der Nase 6 nach außen. Da der Scharnierbolzen 4 und die Nase 6 in den oberen Bereich 11 der Aussparung 8 nur passen, wenn die Seitenwand 1 umgeklappt ist und die Nase 6 vertikal nach unten gerichtet ist, wird während des Aufklappens ausgehend von der oberen Endlage, in welcher sich der Scharnierbolzen 4 im oberen Bereich 11 befindet, der Scharnierbolzen 4 dem unteren Bereich 12 der Aussparung 8 zugeführt. FIG. 7 shows an intermediate position when opening or closing the side wall 1 in the sectional plane along the line ZZ. If the side wall 1, starting from the in FIG. 3 unfolded upper end position, then hits due to the caused by the folding movement of the hinge pin 4, the nose 6 on an inner side 25 of the inner wall 10 of the skirt 7. In this case, the side wall 1 displaced by means of the nose 6 to the outside. Since the hinge pin 4 and the nose 6 in the upper portion 11 of the recess 8 only fit when the side wall 1 is folded and the nose 6 is directed vertically down, is during the unfolding from the upper end position, in which the hinge pin 4 in the upper region 11, the hinge pin 4 is supplied to the lower region 12 of the recess 8.

Ausgehend von der in Figur 1 dargestellten ersten Endlage ist die Seitenwand 1 jedoch um eine raumfeste Drehachse in die aufgeklappte Stellung überführbar bis der Vorsprung 24 gegen den Anschlag 21 anschlägt und dadurch die Drehung begrenzt.Starting from the in FIG. 1 shown first end position, the side wall 1, however, can be converted to a fixed axis of rotation in the unfolded position until the projection 24 abuts against the stop 21 and thereby limits the rotation.

In den Figuren 8 bis 11 sind Ausschnitte von Seitenwänden in Draufsicht zur Darstellung verschiedener Ausführungsformen von Scharnierelementen 26 dargestellt. Die Auswahl soll die Erfindung in keiner Weise einschränken sondern lediglich beispielhaft Möglichkeiten aufzeigen, die Erfindung zu verwenden. An der Seitenwand 1 sind in Richtung des Behälterbodens 2 zwei Fortsätze ausgebildet. Die in Figur 8 dargestellten Fortsätze 27 weisen einen rechteckigen Grundriss und die in Figur 9 dargestellten Fortsätze 28 weisen einen trapezförmigen Grundriss auf. Es können wie in Figur 10 dargestellt auch stabförmige Fortsätze 29 aus der Seitenwand 1 hervorstehen oder das Scharnierelement 26 kann wie in Figur 11 dargestellt in die Seitenwand 1 eingelassen sein. Am unteren Ende des Fortsatzes können sowohl ein Scharnierbolzen 4 als auch mehrere Scharnierbolzen 4 angeordnet sein. Der Scharnierbolzen 4 ist abgesehen von seiner Nase 6 üblicherweise als Zapfen ausgebildet und kann Material sparende Ausnehmungen aufweisen.In the FIGS. 8 to 11 are cutouts of side walls in plan view to illustrate various embodiments of hinge elements 26 shown. The choice is not intended to limit the invention in any way but merely exemplify ways to use the invention. On the side wall 1 two extensions are formed in the direction of the container bottom 2. In the FIG. 8 illustrated extensions 27 have a rectangular plan and the in FIG. 9 shown Projections 28 have a trapezoidal floor plan. It can be like in FIG. 10 also shown rod-shaped projections 29 protrude from the side wall 1 or the hinge member 26 may, as in FIG. 11 shown in the side wall 1 be embedded. At the lower end of the extension both a hinge pin 4 and a plurality of hinge pins 4 may be arranged. The hinge pin 4 is apart from its nose 6 usually designed as a pin and can have material-saving recesses.

Die Erfindung ist nicht darauf beschränkt, dass der Scharnierbolzen 4 als Teil der Seitenwand 1 ausgebildet ist und die Scharnierbolzenaufnahme 5 als Teil des Behälterbodens 2 ausgebildet ist, d.h. der Scharnierbolzen kann als Teil des Behälterbodens 2 ausgebildet sein und mit einer Scharnierbolzenaufnahme zusammen wirken, die als Teil der Seitenwand 1 ausgebildet ist.The invention is not limited to that the hinge pin 4 is formed as part of the side wall 1 and the hinge pin receptacle 5 is formed as part of the container bottom 2, i. the hinge pin may be formed as part of the container bottom 2 and cooperate with a hinge pin receptacle, which is formed as part of the side wall 1.
