Description

Die Erfindung betrifft eine zusammenklappbare Transportkiste, die aus einem Boden und vier gelenkig mit diesem Boden verbundenen Wänden besteht, die mit Kopplungselementen zum Miteinanderverbinden benachbarter Wände in hochgeklappter Stellung versehen sind, wobei die gelenkigen Verbindungen zwischen mindestens zwei sich einander gegenüberliegenden Wänden und dem Boden durch eine Zapfen-Nut-Verbindung gebildet wird, die eine vertikale und eine horizontale Bewegung dieser Wände über einen durch die Abmessungen der Nuten bestimmten Abstand ermöglicht. Dieser stand der Technik entspricht dem Oberbegriff des Patentanspruchs 1 und ist aus der GB.A.1547179 bekannt.The invention relates to a collapsible transport box, which consists of a floor and four articulated walls connected to this floor, which are provided with coupling elements for connecting together adjacent walls in the folded position, the articulated connections between at least two opposing walls and the floor by a Pin-groove connection is formed, which allows vertical and horizontal movement of these walls over a distance determined by the dimensions of the grooves. This prior art corresponds to the preamble of claim 1 and is known from GB.A.1547179.

Derartige Transportkisten nehmen in zusammengeklapptem Zustand einen minimalen Raum ein, was beim Lagern und Transportieren von leeren Kisten von Vorteil ist. Im Sinne der vorliegenden Anmeldung wird unter vertikal im wesentlichen senkrecht auf dem Boden und unter horizontal im wesentlichen parallel zu diesem Boden verstanden, unabhängig von der Lage des Bodens in bezug auf die horizontale Ebene. Aus der FR-A 2 272 907 ist eine zusammenklappbare Transportkiste bekannt, bei der zwei einander gegenüber angeordnete Wände mit länglichen Nuten versehen sind, die mit am Boden angebrachten Zapfen zusammenwirken und wobei die Kopplungselemente zwischen benachbarten Wänden aus zusammenwirkenden L-förmigen Nuten und hammerkopfförmigen Nocken bestehen. Das Verbinden benachbarter Wände erfolgt dadurch, daß diese Nocken durch horizontale Bewegung eines Wandpaares in die Nuten des anderen Wandpaares eingebracht werden und danach das erste Wandpaar heruntergelassen wird, so daß sich die Nocken im vertikalen Teil der L-förmigen Nuten verschieben. Das Entkoppeln erfolgt dadurch, daß zuerst das erste Wandpaar hochgezogen und danach nach außen gedrückt wird, wonach die Wände heruntergeklappt werden können.Such transport boxes take up minimal space when folded, which is advantageous when storing and transporting empty boxes. For the purposes of the present application, vertical is understood to mean essentially vertical on the floor and horizontal essentially parallel to this floor, regardless of the position of the floor in relation to the horizontal plane. From FR-A 2 272 907 a collapsible transport box is known, in which two walls arranged opposite one another are provided with elongated grooves, which cooperate with pegs attached to the floor, and the coupling elements between adjacent walls made of interacting L-shaped grooves and hammer-head-shaped cams consist. The connection of adjacent walls is carried out by introducing these cams into the grooves of the other wall pair by moving one pair of walls horizontally and then lowering the first pair of walls so that the cams move in the vertical part of the L-shaped grooves. The decoupling is done by first pulling up the first pair of walls and then pushing them outwards, after which the walls can be folded down.

Um es bei der bekannten Kiste zu ermöglichen, daß die Wände so nach innen geklappt werden können, daß das eine Wandpaar flach auf dem anderen Wandpaar aufliegt, werden die Gelenkzapfen auf verschiedener Höhe über dem Boden angebracht (Fig. 4) oder die Nuten der Zapfen-Nut-Verbindung L-förmig ausgeführt (Fig. 5).In order to make it possible in the known box that the walls can be folded inwards so that one pair of walls lies flat on the other pair of walls, the pivot pins are attached at different heights above the floor (FIG. 4) or the grooves of the pins - L-shaped groove connection (Fig. 5).

Ein Nachteil der bekannten Kiste ist, daß die Verbindung zwischen den Wänden im gebrauchsfähigen Zustand der Kiste nicht in vertikaler Richtung verriegelt ist. Hierdurch können sich die durch die Zapfen-Nut-Verbindung mit dem Boden verbundenen Wände in bezug auf die benachbarten Wände nach oben bewegen, wenn die Kiste beim Hochheben fest an den erstgenannten Wänden gepackt wird. Ein weiterer Nachteil besteht darin, daß durch die komplizierte Konstruktion der Kopplungselemente die Wände der Kiste schwierig durch Spritzgießen eines thermoplastischen Kunststoffes hergestellt werden können.A disadvantage of the known box is that the connection between the walls in the usable state of the box is not locked in the vertical direction. As a result, the walls connected to the floor by the pin-groove connection can move upward with respect to the adjacent walls if the box is firmly packed on the first-mentioned walls when being lifted up. Another disadvantage is that the complicated construction of the coupling elements makes it difficult to produce the walls of the box by injection molding a thermoplastic.

Aus der GB-A-1 547 179 ist weiterhin eine Kiste bekannt, bei der die Kopplung zwischen den benachbarten Wänden durch einen unter horizontalem Federdruck stehenden kugelförmigen Nocken an der einen Wand erfolgt, der in eine Aussparung in der benachbarten Wand aufgenommen wird. Diese Kiste weist im wesentlichen dieselben Nachteile auf wie die aus der FR-A-2 272 907.From GB-A-1 547 179 a box is also known in which the coupling between the adjacent walls is carried out by a spherical cam under horizontal spring pressure on one wall, which is received in a recess in the adjacent wall. This box has essentially the same disadvantages as that from FR-A-2 272 907.

Die Erfindung schlägt eine einfache Konstruktion vor, bei der die Verbindung zwischen den Wänden im gebrauchsfähigen Zustand der Kiste in allen Richtungen verriegelt ist, und welche sich ausnehmend gut zur Herstellung durch Spritzgießen eines thermoplastischen Kunststoffes eignet.The invention proposes a simple construction in which the connection between the walls in the usable state of the box is locked in all directions, and which is exceptionally well suited for production by injection molding a thermoplastic.

Das wird dadurch erreicht, daß die Nut jeder Zapfen-Nut-Verbindung eine - von der Innenseite der Kiste aus gesehen - konvexe Krümmung aufweist wobei der Abstand zum Boden am äunßersten Ende der Nut größer ist als am der Mitte der Kiste zugewandten Ende. Und daß die Kopplungselemente einer Wand aus sich im oberen Bereich dieser Wand befindlichen vertikalen Nocken bestehen und die Kopplungselemente einer benachbarten Wand aus sich im oberen Bereich dieser Wand befindlichen schalen-oder köcherförmigen Elementen bestehen, so daß beim Hochbewegen der mit einer Zapfen-Nut-Verbindung versehenen Wand die Nocken der einen Wand in die schalen-oder köcherförmigen Elemente der benachbarten Wand einschiebbar sind.This is achieved in that the groove of each pin-groove connection has a convex curvature, as seen from the inside of the box, the distance from the floor at the outermost end of the groove being greater than at the end facing the center of the box. And that the coupling elements of a wall consist of vertical cams located in the upper area of this wall and the coupling elements of an adjacent wall consist of shell-shaped or quiver-shaped elements located in the upper area of this wall, so that when moving up with a pin-groove connection provided wall, the cams of one wall can be inserted into the shell-shaped or quiver-shaped elements of the adjacent wall.

Die mit der Zapfen-Nut-Verbindung versehenen Wände befinden sich nun beim Gebrauch der Transportkiste in ihrer höchsten Stellung, so daß die Kiste an diesen Wänden hochgehoben werden kann, ohne daß die Gefahr besteht, daß die Verbindung zwischen benachbarten Wänden entriegelt wird. Die Nuten der Zapfen-Nut-Verbindung werden vorzugsweise in einem hochstehenden Randteil des Bodens angebracht und können verschiedene Formen haben,, wie z.B. kreisbogenförmig, schräg ansteigend, geknickt usw., wobei alle Formen gemeinsam haben, daß der Abstand zum Boden am äußersten Ende der Nut größer ist als das an der Mitte der Kiste zugewandten Ende.The walls provided with the pin-groove connection are now in their highest position when using the transport box, so that the box can be lifted up on these walls without the risk that the connection between adjacent walls is unlocked. The grooves of the spigot-groove connection are preferably made in a raised edge part of the floor and can have different shapes, e.g. arcuate, sloping, kinked, etc., all shapes have in common that the distance to the bottom at the extreme end of the groove is greater than the end facing the center of the box.

Indem die Nuten am äußersten Ende mit einer Aussparung zum fixieren der Gelenkzapfen in der nach außen versetzten Stellung versehen werden, kann das unbeabsichtigte Entriegeln der Wände durch einen Stoß gegen die mit der Zapfen-Nut-Verbindung versehenen Wände verhindert werden. Das kann auch dadurch erreicht werden, daß der hochstehende Rand mit Schwellen versehen wird, über die die mit der Zapfen-Nut-Verbindung versehenen Wände bei Bewegung nach außen gedrückt werden müssen. Weiterhin können die mit der Zapfen-Nut-Verbindung versehenen Wände an der Unterseite mit Randleisten versehen werden, die in Fugen im hochstehenden Rand des Bodens eingreifen. Diese Konstruktion kann gegebenenfalls als Schnappverbindung ausgeführt werden.By providing the grooves at the extreme end with a recess for fixing the pivot pins in the outwardly displaced position, the unintentional unlocking of the walls can be prevented by a push against the walls provided with the pin-groove connection. This can also be achieved in that the upstanding edge is provided with thresholds, via which the walls provided with the pin-groove connection must be pressed outwards during movement. Furthermore, the walls provided with the mortise and tenon connection on the underside Edge strips are provided, which engage in joints in the raised edge of the floor. This construction can optionally be carried out as a snap connection.

Vorzugsweise werden die Kopplungselemente der mit der Zapfen-Nut-Verbindung versehenen Wände in gebrauchsfähigem Zustand von oben durch die Kopplungselemente der angrenzenden Wände umfaßt. Das Koppeln bzw. Entkoppeln benachbarter Wände erfolgt dann automatisch, wenn die mit der Zapfen-Nut-Verbindung versehenen Wände in Querrichtung bewegt werden und sich dadurch nach oben bzw. nach unten bewegen. Die Kopplungselemente können dazu z.B. aus zusammenwirkenden Nocken und schalen- oder köcherförmigen Elementen bestehen. Die miteinander verbundenen Wände können dann im Bereich der Kopplungselemente nicht in seitlicher Richtung in bezug aufeinander bewegt werden. Eine solche Konstruktion der Kopplungselemente bringt beim Herstellen der Wände durch Spritzgießen eines thermoplastischen Kunststoffes keine Schwierigkeiten mit sich.In a usable state, the coupling elements of the walls provided with the pin-groove connection are preferably encompassed from above by the coupling elements of the adjacent walls. The coupling or uncoupling of adjacent walls takes place automatically when the walls provided with the pin-groove connection are moved in the transverse direction and thereby move upwards or downwards. The coupling elements can e.g. consist of interacting cams and bowl-shaped or quiver-shaped elements. The interconnected walls can then not be moved in the lateral direction in relation to one another in the area of the coupling elements. Such a design of the coupling elements does not pose any difficulties when the walls are produced by injection molding a thermoplastic.

Zum Zusammenklappen der erfindungsgemäßen Transportkiste genügt es, die Unterkante der mit der Zapfen-Nut-Verbindung versehenen Wände etwas nach innen zu drücken, wodurch sie sich so weit senken, daß die Verbindung zwischen den Wänden entkoppelt wird, wonach die Wände nach innen geklappt werden können.To fold the transport box according to the invention, it is sufficient to push the lower edge of the walls provided with the pin-groove connection inwards, whereby they lower so far that the connection between the walls is decoupled, after which the walls can be folded inwards .

Die Erfindung wird anhand des in der Zeichnung wiedergegebenen Ausführungsbeispiels näher erläutert:

  • Fig. 1 ist eine perspektivische Ansicht einer erfindungsgemäßen Transportkiste;
  • Fig. 2 zeigt eine Vorderansicht und teilweise einen vertikalen Schnitt über den Gelenkzapfen;
  • Fig. 3 eine Seitenansicht und teilweise einen Schnitt nach der Linie 111 - 111 in Fig. 2 dieser Transportkiste. Die Transportkiste besteht aus einem Boden 1, zwei mit einer Zapfen-Nut-Verbindung mit dem Boden verbundenen Seitenwänden 2 und zwei mit festen Gelenken mit dem Boden verbundenen Seitenwänden 3.
The invention is explained in more detail with reference to the embodiment shown in the drawing:
  • 1 is a perspective view of a transport box according to the invention;
  • Fig. 2 shows a front view and partially a vertical section over the hinge pin;
  • Fig. 3 is a side view and partially a section along the line 111-111 in Fig. 2 of this transport box. The transport box consists of a base 1, two side walls 2 connected to the base with a pin-groove connection and two side walls 3 connected to the base with fixed joints.

Der Boden ist mit einem rundumlaufenden hochstehenden Rand 4 versehen. In diesem Rand sind Nuten 5 angebracht, worin sich an der Unterkante der Seitenwände 2 angebrachte Zapfen 6 befinden. Die Nuten bestehen aus einem äußeren, horizontalen-Teil 5' und einem inneren, zum Boden hin geneigten Teil 5". Die Höhe der Randteile 4', in denen sich die Nuten befinden, ist etwas größer als die Höhe des Randes an anderen Stellen. Die Zapfen 6 können bei der Herstellung der Wände 2 mit diesen einstückig ausgebildet werden. Die Seitenwände 3 sind durch feste Gelenke 7 mit dem Bodenrand 4 verbunden. Dies können sowohl Zapfen-Gelenke als auch sogenannte Filmgelenke aus Polypropylen sein.The floor is provided with an all-round raised edge 4. Grooves 5 are provided in this edge, in which there are pins 6 attached to the lower edge of the side walls 2. The grooves consist of an outer, horizontal part 5 'and an inner part 5 "which is inclined towards the floor. The height of the edge parts 4' in which the grooves are located is somewhat larger than the height of the edge at other locations. The pins 6 can be formed in one piece with the walls 2 in the production of the walls 2. The side walls 3 are connected to the bottom edge 4 by fixed joints 7. These can be both pin joints and so-called film joints made of polypropylene.

In heruntergeklappter Stellung liegen die Seitenwände 2 unmittelbar auf dem Boden auf. In dieser Lage befinden sich die Zapfen 6 auf dem niedrigsten Punkt des abfallenden Teils 5" der Nuten 5, so daß die Wände 2 sich zwischen den hochstehenden Rändern 4 befinden. Die Gelenke 7 sind auf dem Rand angebracht, so daß die Seitenwände 3 in heruntergeklappter Stellung auf den Seitenwänden 2 liegen. Die Höhe der Wände und die Abmessungen des Bodens sind in dem dargestellten Ausführungsbeispiel so gewählt, daß einander gegenüberangebrachte Wände sich in heruntergeklappter Stellung nicht überlappen. Es ist aber auch möglich, die Abmessungen des Bodens und der Wände so zu wählen, daß die Seitenwände 3 und gegebenenfalls auch die Seitenwände 2 sich in heruntergeklappter Stellung paarweise überdecken.In the folded-down position, the side walls 2 lie directly on the floor. In this position, the pins 6 are located on the lowest point of the sloping part 5 "of the grooves 5, so that the walls 2 are between the upstanding edges 4. The joints 7 are mounted on the edge, so that the side walls 3 are folded down Position on the side walls 2. The height of the walls and the dimensions of the floor are selected in the illustrated embodiment so that walls placed opposite one another do not overlap in the folded-down position, but it is also possible to increase the dimensions of the floor and walls choose that the side walls 3 and possibly also the side walls 2 overlap in pairs in the folded-down position.

Die Oberkante der Wände 3 ist an den Enden mit an der Unterseite offenen, schalenförmigen Kopplungselementen 8 versehen. Die Kiste wird dadurch in gebrauchsfähigen Zustand gebracht, daß erst die Wände 3 hochgeklappt werden und danach die Wände 2. Die gelenkige Verbindung zwischen den Wänden 3 und der Oberkante 4 ist so ausgeführt, daß diese Wände nicht über die vertikale Stellung hinaus nach außen schwenken können. Die hochgeklappten Wände 2 werden dann nach außen gedrückt. Hierbei bewegen sich die Zapfen 6 über den abfallenden Teil 5" zum höher gelegenen Teil 5' der Nuten 5. Die Wände 2 werden hierbei nach oben bewegt, wodurch nockenförmige Kopplungselemente 9 an den Enden der Oberkante dieser Wände in die schalenförmigen Kopplungselemente 8 der Wände eingreifen. Das Plazieren der Wände 2 kann dadurch bewerkstelligt oder unterstützt werden, daß mit Hilfe von in diesen Wänden angebrachten Handgriffen 10 die Wände 2 hochgezogen werden. Die Nocken 9 befinden sich in Aussparungen 11, die an den Enden der Oberkante der Wände 2 in dieser Kante angebracht sind. Sie überragen hierdurch die Oberkante der Transportkiste nicht - genau wie die schalenförmigen Kopplungselemente 8, die über die Nocken 9 gestülpt sind, wie in Fig. 2 dargestellt ist.The upper edge of the walls 3 is provided at the ends with shell-shaped coupling elements 8 which are open on the underside. The box is brought into a usable condition in that first the walls 3 are folded up and then the walls 2. The articulated connection between the walls 3 and the upper edge 4 is designed so that these walls cannot pivot outwards beyond the vertical position . The folded-up walls 2 are then pressed outwards. Here, the pins 6 move over the falling part 5 "to the higher part 5 'of the grooves 5. The walls 2 are moved upwards, whereby cam-shaped coupling elements 9 at the ends of the upper edge of these walls engage in the shell-shaped coupling elements 8 of the walls The placement of the walls 2 can be accomplished or supported in that the walls 2 are pulled up with the aid of handles 10 mounted in these walls. The cams 9 are located in recesses 11 which are located at the ends of the upper edge of the walls 2 in this edge As a result, they do not protrude above the upper edge of the transport box - just like the shell-shaped coupling elements 8, which are placed over the cams 9, as shown in FIG.

Die Wände 2 sind an der Unterseite mit einer nach außen weisenden Randleiste 12 versehen, die in eine Fuge 13 des Bodenrandes 4 eingreift, wenn die hochgeklappten Wände 2 nach außen gedrückt werden. Hierdurch wird die Gefahr, daß diese Wände durch einen Stoß gegen die Unterkante unbeabsichtigt entriegelt werden, vermindert. Die Randleiste und die Fuge können gegebenenfalls als Schnappverbindung ausgeführt sein. Weiterhin kann dem unbeabsichtigten Entriegeln dadurch begegnet werden, daß der horizontale Teil 5' der Nuten am Ende mit einer Aussparung zum Fixieren der Zapfen 6 im gebrauchsfähigen Zustand der Kiste versehen wird oder daß der Rand 4 an der Oberseite stellenweise mit Schwellen versehen wird, worüber die Wände 2 bei der Bewegung nach außen gedrückt werden-müssen.The walls 2 are provided on the underside with an outwardly facing edge strip 12 which engages in a joint 13 of the bottom edge 4 when the folded-up walls 2 are pressed outwards. This reduces the risk of these walls being unintentionally unlocked by an impact on the lower edge. The edge strip and the joint can optionally be designed as a snap connection. Furthermore, the unintentional unlocking can be countered by the fact that the horizontal part 5 'of the grooves is provided at the end with a recess for fixing the pins 6 in the usable state of the box, or that the edge 4 is partially provided with sleepers at the top, about which the Walls 2 must be pressed outwards during the movement.

Die erfindungsgemäße Transportkiste wird vorzugsweise durch Spritzgießen aus einem thermoplastischen Kunststoff, wie z.B. Polyäthylen, Polypropylen, Polystyrol usw., hergestellt.The transport box according to the invention is preferably injection molded from a thermoplastic, such as polyethylene, polypropylene, polystyrene, etc., produced.

Die erfindungsgemäße Transportkiste eignet sich sehr gut zur Verwendung als Einkaufskiste beim Transporheren von Ladenwaren.The transport box according to the invention is very well suited for use as a shopping box when transporting shop goods.
