The present invention relates to a transport and storage container for transporting and providing objects, particularly vehicle accessory pieces, in the field of assembly lines, the container comprising a bottom plate, a first front side wall and an opposite second front side wall, a rear side wall, a front side wall opposite the rear side wall, and a pivotably fastened lid opposite the bottom plate, the container in the empty state being reducible in size in its outer dimensions by the walls being pivoted at least in part relative to one another, to which end bottom plate and walls and walls with walls are connected by hinges.
Transport containers, as have been indicated above, are used in many ways for transporting the most different objects. To be more specific, such transport containers are used in the car industry to transport accessory parts, subassemblies, or other parts required for the assembly of a vehicle from the supplier to the car manufacturer. Such transport containers are then erected at the assembly line of the car manufacturer to remove the parts delivered in them and to mount them on the vehicle.
These transport containers must be very stable so that the parts transported in them do not get damaged. The transport containers must also be reusable to use them repeatedly for the intended transportation. That is why such containers are normally made from metal, whereby they have a considerable weight.
A further demand which is made on such containers is the demand to observe predetermined base area dimensions. Standard containers, as are used in the above-mentioned field, have a length of 1150 mm, a width of 1000 mm and a height of 1000 mm. Moreover, dimensions of 1200×1000×1000 or 1200×800×1000 (each time length×width×height) are standard. Containers of such sizes are above all the subject matter of the present invention.
Since the emptied containers must be transported back again to the supplier, it is necessary, for keeping the transportation costs low, that the empty transport and storage containers can be reduced in their outer dimensions, i.e. they must be disassembled or collapsed, but at the same time they must not exceed the predetermined base area dimension, also in the collapsed or folded state.
A further demand which is made on such a transport and storage container is the demand that, apart from a lid opposite the bottom plate, a front side wall can also be opened so that the parts provided in the container can be removed at the assembly line. At the same time, the containers must be stackable, so that during assembly also several containers can be put one on top of the other so as to remove the parts through the respective opened front side walls subsequently.
Starting from the above-described prior art and the corresponding preconditions the transport and storage containers of such type must satisfy, it is the object of the present invention to develop a transport and storage container of the above-described type such that safe transportation of the objects is ensured, that objects can be removed easily, and that the container can also be transported in the empty state in a space-saving manner without the need for handling a large number of individual parts.
This object is achieved according to the invention by a transport and storage container according to claim 1. Further preferred developments of the transport and storage container are indicated in the dependent claims.
Hence, a transport and storage container is provided which comprises both a lid and front door leaves, so that the parts to be stowed away accordingly in the container can be introduced into or removed from the container from above via the lid and also via the front door opening. At the same time, however, it is also possible to collapse the transport and storage container such that in the collapsed state it has a substantially smaller overall height and can be transported and stored thereby in a space saving manner in the empty state. It is here of advantage that all parts, i.e. the bottom plate, the front side walls, the rear wall and the lid and the door leaves, are also connected to one another in the collapsed state, via corresponding hinges. No individual parts have to be handled, neither during unfolding of the transport and storage container nor during collapsing of the container. Moreover, the container is constructionally designed such that it can particularly be made from stable materials, such as metal, but nevertheless has a relatively low weight, despite its high stability, due to the construction according to the invention.
To accomplish a condition where the first door leaf lies flat on the bottom plate during collapsing of the container, the pivot axis between the bottom plate and the first front side wall should be located at a corresponding distance above the plane of the bottom plate. Thanks to such a flat support of the individual plates of the container, i.e. not only of the bottom plate and the first front side wall, but also of the other walls, an overall height that is as small as possible is accomplished in the collapsed state.
Furthermore, the pivot axis between the bottom plate and the second front side wall should be located at a distance above the plane of the bottom plate which approximately corresponds to the sum of the thickness of the first front side wall and the first door leaf. For instance, the first front side wall and the first door leaf can be accommodated under this second front side wall and the second door leaf.
Likewise, the pivot axis between the bottom plate and the rear side wall should be located at a distance above the plane of the bottom plate which corresponds approximately to the sum of the thickness of the first front side wall and the first door leaf and the thickness of the second front side wall and the second door leaf, so that rear side wall and lid can rest flat on the second front side wall positioned thereunder.
To achieve the corresponding position of the pivot axis of the first front side wall, the pivot axis is formed on the upper edge of a stationary section which is connected to the bottom plate and pertains to the first front side wall.
This applies equally to the pivot axis of the second front side wall which is preferably formed on the upper edge of a stationary section which is connected to the bottom plate and pertains to the second front side wall.
Preferably, the pivot axis of the rear side wall should also be formed on the upper edge of a stationary section which is connected to the bottom plate and pertains to the rear side wall, by corresponding members.
To be able to firmly close the container during transportation in its unfolded state, the respective door leaves are each lockable to the bottom plate on the one hand and to the lid on the other hand by at least one lock. In a simple form, this lock is formed by two bolts, at the top and at the bottom on the door, which engage into the bottom plate and the lid, respectively.
Likewise, a lock that stiffens the container can be provided, which lock clamps the bottom plate against the lid. Such a lock can be formed by a pivot arm which is pivotably held on the door leaf.
Preferably, such a pivot arm then engages with its ends into a respective locking nose on the bottom plate and on the lid.
To design this pivot arm in a constructionally simple way, the center of gravity of the pivot arm should be arranged approximately at half the height of the door leaf.
As has already been mentioned at the outset, an imperative demand is that such a transport and storage container, also in the collapsed state, should not exceed the base area dimension predetermined by the bottom plate, in a projection onto the bottom plate. This is not the case if the height of the rear side wall which is folded over is smaller than the width of the lid. In such a case the lid which is pivoted onto the outer side of the rear side wall is then projecting with its edge beyond the rear side wall, namely at the side of the rear side wall on which the hinge is located. As a result, the base area dimension is exceeded by the projecting part of the lid. To avoid such a state, the pivot axis is formed between the rear side wall and the lid by at least one corresponding hinge which is assigned to the lid, and said hinge is retained with the lid in a guide arrangement on the rear side wall such that the hinge can be spaced apart from the associated longitudinal edge of the rear side wall. This means that with such an arrangement the lid folded onto the outer side of the rear wall can be shifted such that the edge of the lid portion projecting beyond the base area dimension ends with the edge of the bottom plate.
Such a guide arrangement can be formed by two rods, each of said rods being guided in a sleeve assigned to the rear side wall.
The two rods can here be formed by the free ends of a U-shaped stirrup, with the transverse member of the U-shaped stirrup connecting the two ends being assigned to the lid.
It is here also possible that the lid is subdivided into two parts that are connected with a hinge, so that the part of the lid projecting beyond the basic dimension in the collapsed state can be folded inwards onto the other lid part. This, however, increases the height of the collapsed transport and storage container by the thickness of the folded-over lid part.
To create a stable connection between the door leaves and the associated front side walls, the respective pivotable connection between the first front side wall and the first door leaf and between the second front side wall and the second door leaf is formed by a tubular arrangement, with a thicker tube section assigned to the door leaf, and a thinner tube section assigned to the front side wall. The thin tube section which is assigned to the front side wall is only retained on its upper and lower end, so that the thick tube section with the door leaf attached thereto can rotate freely around the thin tube section.
To enhance the stability of the container even further, reinforcement plates may be arranged in the corner portions of the bottom plate and the side walls, the rear wall and the door leaves.
Furthermore, it is preferred that the length of the thicker tube section is chosen such that it is smaller than the height of the side edge of the door leaf and the front side wall, respectively. The door leaf can thereby be lifted and lowered again to disengage it e.g. from corresponding locking members or to bring it again into engagement with such locking members. If the container comprises the above-mentioned reinforcement plates, the thick tube section should have a length corresponding to the length of the side edge of the front side wall minus the height of these reinforcement plates, so that the thick tube section of the door leaf can be lifted above the reinforcement plate. The door leaf can thereby for instance be disengaged from a locking with the reinforcement plate.
To be able to stack containers safely one on top of the other, but also to be able to grip them with fork-lift trucks, base members are formed on the bottom side of the bottom plate, the base members resting on the inner side of an edge formed on the outer side of the lid, with the containers being stacked one on top of the other. An edge height of a few millimeters is here sufficient.
Further details and features of the invention become apparent from the following description of an embodiment with reference to the drawings. In the drawing,

It should be noted that, as far as reference is made to hinges in the figures, the figures just show the corresponding pivot axes.
Furthermore, the second door leaf 6, which is the left one in
The first front side wall 2 is pivotable around a hinge 15 in the direction of the pivot arrow 16 and the pivot arrow 17, respectively, towards the bottom plate 1. This is also true for the second front side wall 3 which is pivotable about a pivot axis 18 in the direction of the pivot arrow 19 and 20, respectively. As can be seen in
Finally, the rear side wall 4 is held on the bottom plate 1 and on an edge strip 23, respectively, which is firmly connected to the bottom plate 1 and forms part of the rear side wall 4, via a hinge 24 which is pivotable about the pivot axis 25. The lid 7 is connected to the upper edge of the rear side wall 4 by means of a hinge 26 which in the direction of the pivot arrow 27 can be pivoted by 270° outwards in such a manner that the lid 7 comes to rest with its outer side on the outer side of the rear side wall 4.
To collapse the transport container of
After the locks have been unlocked, the right first door leaf 5 is first pivoted onto the inner side of the first front side wall 2. Thereupon the front side wall 2 is pivoted, with the first door leaf 5 being positioned thereunder, around the hinge 15 towards the bottom plate 1 and placed on the bottom plate 1. This arrangement of bottom plate 1, first door leaf 5 and first front side wall 2 can be seen in
To permit such a shifting of the lid 7,
The shifting of the lid 7 relative to the rear side wall 4 can also be accomplished in a different way. However, the shift mechanism should be kept as flat as possible so that the overall height of the transport container in the collapsed state is not excessively increased.
As can be seen with reference to
It goes without saying that different technical details can be modified by virtue of the technical knowledge of a skilled person or can also be realized technically. Of importance to the transport container of the type in question, as has been described above, is the principle how its individual members can be collapsed such that they are space-saving, do not exceed the basic size, but are also very stable in the unfolded state and can particularly also be made from metal.
