Definitions

  • the invention relates to folding containers made of plastic for the transport of objects such as fruit and vegetables, which has side walls which can be folded inwards, so that the container is folded from a receiving position in which the side walls are perpendicular with respect to the floor Position can be transferred in which the container can be stowed without taking up much space.
  • folding containers are already known in different embodiments.
  • articulated hinges are used as joints, which, however, predominantly represent the weak point of such a folding container because they can be damaged under load and frequent use.
  • Such containers which represent bulk goods, are not handled with care when in use, rather they are usually opened very quickly and with force, which, in the event that the hinge joints are not extremely robust, can lead to immediate damage.
  • the hinges are again robust, the hinges take up a lot of unnecessary space and also increase the total weight of the folding container, which in turn is disadvantageous for handling.
  • the object of the invention is to provide a folding container which can be easily assembled and disassembled, is of extremely stable and robust construction and in which the hinges no longer form the weak point of the folding container.
  • the container should be easy to handle.
  • the articulated hinges are designed in one piece as an eyelet and pin with container parts and each hinge has at least one articulated pin and at least one articulated eye, the articulated eye being divided into two parts or two halves, one of which forms a fixed hinge part and the other is hinged onto the fixed hinge part after removal from the injection mold and can be firmly locked.
  • the mounting hinge is connected in one piece to the fixed hinge part via a hinge-like hinge.
  • the hinge eyelet for example, the bottom of the container can be formed in one piece with the hinge mechanism. In the injection molding position, the fixed hinge part and the assembly hinge part are opened next to each other and are connected by a film-like joint.
  • the assembly hinge part After being lifted out of the injection mold, the assembly hinge part can be folded over the film hinge onto the fixed hinge part and locked with it, the hinge pin, which is preferably formed in one piece on a foldable side wall part, being framed between the two hinge halves.
  • the fixed hinge part is formed in an edge profile of the floor, whereas the assembly hinge part is integrated in a profile bar that can be opened onto this edge profile or vice versa.
  • the profile base In the folded-up position of the profile strip on the edge profile, the profile base is supported on the edge profile via contact areas, the load being transmitted from the side walls via these contact areas.
  • the hinge mechanism essentially does not participate in the load transmission, so that separate segments for the power transmission and for the pivoting movement are formed by the profile strip.
  • Another advantage of the invention is that when the side walls are pressed out, tension occurs via the contact surfaces and the movement of the side walls to the outside is blocked. Even in this case, the hinges are not loaded and the container is in a stable unfolded position.
  • a plurality of closely spaced joint hinges are expediently used in alignment per side wall, so that the joint hinges are arranged in the manner of a ring binder. If a hinge fails due to breakage or other damage, the function is taken over by the other hinge.
  • the side walls are locked together by locking mechanisms, the locking taking place by locking lugs which are arranged on the side edges of two opposite side walls.
  • the locking lugs engage behind corresponding locking hooks in the side walls which are arranged in a corner. If one wants to move the folding container from its erected position into the folding position, one only has to press the V-shaped or U-shaped locking lugs together so that the locking lugs can be guided past the locking hooks and thus folded inwards through the side wall can be.

S longitudinal side walls 3, on which there are handle openings 4 formed by recesses. All four side walls 2, 3 can be folded inwards, namely along the articulated hinges 5, which will be described in more detail below. The folded position of the four side walls results from FIG.
  • raised edge strips 6 and 7 are formed on the bottom 1, to which the side walls are articulated at 8.
  • the height of these raised edge strips is adjusted in such a way that the corresponding side wall, which is articulated thereon, can be folded over another side wall of the container.

This is achieved by the differently high edge trim design in adaptation to the respective folding positions.
  • FIGS. 6-12 show that at the lower edge of the side walls, here for example the narrow side wall 2, a plurality of hinge pins 8 are arranged at regular intervals over the length of the lower edge of the side wall 2, that is to say are molded onto the side wall 2. In Fig. 12, however, only one of the hinge pins 8 can be seen in detail due to the cut, which is formed on two flanges 9 and the side wall 2.

If the hinge pin 8 is completely encompassed by the eyelet 10 in this sectional view at the top left in FIG. 12, this is only due to the course of the cutting plane, but it is quite clear, for example, from FIGS Hinge pin 8 is fully received in a circular recess in the hinge eyelet 10, so that a perfect position - and thus hinge function is achieved.

  • the profile bar 13 is folded around the flexible connecting part 14 onto the edge profile 6, so that the latching hook 12 snaps behind a latch 15 which is formed in the edge profile 6.
  • the mounting hinge part 10b reaches the complementary half of the eyelet formed in the edge strip profile 6, so that the eye formation in the profile strip 13 complements the fixed hinge part 10a in the edge strip profile 6 to form the hinge eyelet 10.

  • 10 and 11 show the functional position, ie where the catch (s) engage behind the catch hook 15 and the two eyelet designs 10a, 10b complement each other to form the joint eyelet 10.
  • 10, 11 and 12 it is quite clear that in the functional position of the hinge, where the profile strip 13 is folded onto the edge profile 6, the two eyelet formations 10a, 10b lie on one another with their surface on the parting plane 11, that is 7 for the entire contact area designated 16 to the left and right of the eyelet formation 10b including the projecting leg 17 of the profile strip 13, so that according to FIG. 12 there is a very good contact area over the width of the edge profile 6 and that along the Partition plane 11. If, according to FIG.
  • the long side wall 3 was pressed counterclockwise around the hinge pin 8, the lower side wall surface 18 presses on the profile strip 13 so that it is braced against the edge profile 6.
  • the hinge is not loaded.
  • the contact surfaces 16 lying one on top of the other at the parting plane 11 there is tension and thus an intensification of the joint hinge engagement, the legs 17 of the profile strip 13 and the edge profile 6 pressing together, so that the side walls pivot 2, 3 is effectively blocked to the outside by the formation of the edge profile 6 and the profile 13.
  • This means that the folding container is very effective when ⁇ th position of the side walls secured against an after pivoting the side walls 2, 3, so that a very stable, unfolded position of the side walls is achieved.
  • the profile bar 13 which is in locking engagement with the edge profile 6, forms a flap which prevents the side walls from swinging out further from the upright position. In this position, a very good load transfer in the stack is also possible, while largely relieving the strain on the hinge mechanism. This protects the hinge mechanism accordingly.
  • This design ensures a division into components for the load transmission and for the pivoting movement, so that both the eyes and the pivot pins are largely relieved and are only used for the pivoting movement. As can be seen in particular from FIGS. 3 and 13, a large number of hinges are provided for each side wall, so that a hinge-like hinge formation results.
  • hinge pins or pins 8 can also have a different cross section than the circular cross section shown, for example a three-legged cross section, which is advantageous in terms of production technology. It is expedient if the hinge pins are connected at their two ends to the side walls via flanges 9, since this is advantageous for the stability of the hinge pins.
  • FIG. 17 and 18 show the latching of the unfolded side walls 2, 3, whereby here, for example on the side wall 2 left and right, that is to say in the region of the side walls 3, V or U-shaped latching noses 19 are provided, which are behind accordingly latching hooks 20 of the side walls 3 grip. If you want to fold the side wall 2 inwards onto the floor, you only have to sen 19 are manually compressed so that the front nose portion 21 of the locking lugs 19 passes the locking hook 20 so that the wall 2 can be folded inwards. On the other hand, there is an automatic locking via the locking mechanism if, for example, the wall 2 is inadvertently pressed inwards, since the locking lugs 19 are then braced in front of the locking hook 20.
