EP1288131B1 - Container with foldable wall - Google Patents

Abstract

A container has a horizontal frame (5, 6) linked by upright door battens (4). The battens are supported on one or both sides by transverse diagonal strips (14, 15) linked (Z) by a V-shaped interlocking notch fitting.

Description

The invention relates to a one of its side walls ago loading and unloading folding wall container with at least one removable and adjustable over the Seitenwanderstreckung support part for non-positive connection between the bottom and top part of the container and at least two door panels with side doors, each of two or more are formed by hinges interconnected door wings.

Such folding wall containers are made EP 0554132A . NL 8403373 known.

By the well-known design of a Faltwandcontainers, namely that it can be opened on one of its longitudinal sides, although an advantage is achieved for the loading and unloading, but in comparison to a differently constructed container a significant reduction in strength and rigidity in purchasing be taken. This is particularly noticeable when the charge can not be distributed over a large area over the bottom surface of the container, but due to the nature of the charge only a relatively small footprint is significantly burdened. In practice, it has been helped so far with bracing elements. For example, one has hung a chain there before closing a side door. In this way, if the chain has been dimensioned sufficiently large, a certain remedy can be created. However, this also requires additional assembly work, which is not only annoying, but also dangerous.

Also, a special reinforcement or stiffening of the side doors to solve the problem is out of the question, because this would mean that no hinged doors could be used. Hinged doors are not suitable for receiving the corresponding forces from home, whereas doors with only one door wing require that the necessary clearances are available laterally from the container for loading and unloading.

To eliminate the above-mentioned disadvantages is proposed in a Faltwandcontainer according to claim 1.

It is further known ( DE 21 21 686 A1 ) In a container of a general nature, to provide the doors located on the front sides with a support, with the help of which tensile forces can be absorbed, pressure forces but not. As a result, the torsional stiffness of a container can be improved, but reinforcement or stiffening of a transport container with side doors can not be achieved as a result.

The invention will be explained below with reference to the drawing, for example.

In Fig. 1 a door with three wings 10, 11 and 12 is shown, which are pivotable about vertical pivot axes 111 and 112 to each other, as is usually the case with folding doors for folding wall containers.

In Fig. 1 the door is shown in the closed position, wherein an upper longitudinal spar 5 of the folding wall container and a lower longitudinal spar 6 of the folding wall container each extend over the length of the container. With 4 a vertical support member is designated, which limits the door panel of the folding door to the right side, but is not suitable to record significant vertical forces that could serve the stiffening of the folding wall container. This support member 4 is supposed to look in the direction Fig. 1 from left to right and vice versa to be able to handle the loads better during loading and unloading.

According to a preferred embodiment of the invention, a transverse reinforcement is now provided which extends diagonally to the door panel and bridges the door panel from bottom left to top right. This transverse stiffening consists of three mutually movable pressure bars 13, 14 and 15, which are fixed to the inside of wings 10, 11 and 12 of the door, so that they can join the corresponding pivoting movements of the wings. In Fig. 1 the closed position of the door is shown, so that the elements 13, 14 and 15 are engaged with each other.

Fig. 2 shows an enlarged view of the engagement position of the two pressure rods 14 and 15 to each other. The push rod 14 has an extended end face and can receive the end portion of the other push rod 15 in a recess.

The 3 and 4 show from above from the engagement position of the two pressure bars 14 and 15 in the closed and open position.

The in the Fig. 1 to 4 embodiment shown is based on pressure bars. It is within the scope of the invention to replace these pressure bars by tension rods.

Claims (1)

1. Container with foldable wall loadable and unloadable from one of its side walls, comprising at least one support (4) removable and adjustable through the side wall extent for frictional connection between the bottom and roof part (5, 6) of the container, and comprising at least two door panels with side doors, which are each formed by two or more door wings (10, 11, 12) mutually connected by hinges (111, 112), characterised in that a cross bracing is provided for each door panel, which are each formed by individual struts (13, 14, 15) mounted at the inner surfaces of the wings (10, 11, 12) of the side door, which are arranged in mutual engagement in the closed condition of the door (fig. 3) and transfer forces between the roof part and bottom part and are not engaged in the open position of the door (fig. 4), the struts (13, 14, 15) are each formed as a flat bar having a cross-section increasing their buckling strength, the flat side of which is mounted at the surface of the door wing, and the struts are formed with mutually complementary engagement surfaces at their ends and extent diagonally across the door panel.
