Abstract
ABSTRACT
A container of variable volume includes a main container body having at least one foldable wall element and a drawer-type extension unit to generate an extension providing additional space. The extension has at least a front wall and a pair of side walls or a pair of top and bottom walls. The foldable wall element of the container forms one of the missing top and bottom or the side walls of the extension unit. The other one of the top and bottom or side walls of the drawer-like extension is either another part folded out from the container or is already an integral part of the drawer.
The container has a continuously variable volume and can be better adapted to spatial limitations at the installation site. The interior of the container and the extension is effectively protected from penetration of dampness or contaminants during expansion or retraction of the container.

CONTAINER OF VARIABLT: VOLUME
Tlle invention relates to containers of variable volume.
Containers are normally used for the transportation of goods, but in some instances are utilized -for housing purposes, as workshops, or for tests stands and the like. These latter containers serve not only for the transportation o~ machinery, but must S also provide su-fficient and appropriate living and working space in order for them to appropriately function as a living or working environment.
Since containers are normally transported on trucks, ships or by aircraft, the external dimensions for transportation of a container should be as small as possible, while providing suff1cient internal volume. Since in the case of the above described 10 containers which function as a working or living enviromnent, the working or living space is generally not used during transport of the container, it is particularly desirable to use containers of variable volume. The minimum volume thereby must be sufficient to accommodate all equipment and furnishings of the container during transport, and the n1aximum volume should be as large as possible in order to provide sufficient working 15 andlor living space.
Containers of this type are known and, generally, their volume can be increased on site by folding out additional surface elements which form an extension to the container.
German Utility Model DE-GM 9,113,701 describes such a container, in which 20 the side walls of the container can be folded out. These side walls, when folded out, constitute the floor areas of the extension. The second wall is hingedly connected to each foldable side wall from which a third wall is in turn suspended by hinges. Upon expansion of the container, the second wall becomes an upstanding wall of the extension, and the third wall, folded ~ack towards the container, becomes the ceiling of -25 the extension. The three walls (side wall, second wall and third wall) are thus folded out in a U-shape and in this way forrn tne extension except for the extension side walls. ~ -The necessary side wall elements are driven out from the container and thus close off the extension. The surface elements are hydraulically moved.
It is a significant disadvantage of such a container construction that, during 30 assembly or disassembly of the extension, the container is inevitably open over a large area as a result of the folding out of the side wall. Thus, it is not possible to prevent ,,, ... ... ,, :

In an effort to at least diminish this problem, German Utility Model DE-GM

This object is achieved with a container of variable volume including a main container body having at least a first foldable wall element and a retractable extension unit having at least a front wall and one of a pair of side walls and a pair of top and 30 bottom walls, the extension unit being extendible from one of a side wall, an end wall and a top wall of the main container body, the other of the pair of side walls and the pair of top and bottom walls being respectively selected firom the first foldable wall .. .. . ...
2 lla3~s element, a second foldable wall element of the main container body and an integral part of the extension unit.
According to the invention, a container of variable volume is provided which either has a movable extension that is extendible *om the container as a closed drawer-S type unit with a wall portion of the container forming a cover for the drawer or has atleast one essentially enclosed drawer.
In a preferred embodiment, a wall or wall portion of the container body is folded out as a roof for the drawer, and the roof of this drawer is extended out under the roo-f.
In that embodiment, complete projection is provided for the interior of the container, 10 since the end wall of the extension is positioned behind the movable wall or wall portion of the container which functions as a roof for the drawer. In addition, nothing can penetrate into the roo-fless drawer since the latter is extended out under a roof which is already in place.
In another preferred embodiment, not a wall or wall portion of the container is 15 utilized as roof for the drawer but an element which rests on the roof of the container in the transport condition and can be pivoted through approximately 180 about an upper edge of a container wall. The folded out wall or wall portion of the container can then form a side wall of the extension.
In a further preferred embodiment, the extension drawer does not include a floor20 and a wall element which is folded down from a wall of the container is used as the drawer floor. This element can be a wall or wall portion of the container or a wall which is arranged behind one of the container walls.
In yet another preferred embodiment, at least one wall of the container comprises a double sided flap opening, where by the flaps when swung out form opposite walls of 25 the drawer extension in the extended condition.
All these embodiments in accordance with the invention permit partial extension of the drawer and, thus, a continuous variation of the container volurne. This permits a better adaptation of the expandable container to the external installation conditions on site. The embodiments according to the invention also permit variation of the container 30 volume while the container is kept closed off from the exterior in order to prevent the penetration of the external atmosphere and undesired substances.

Nested drawer-like combinations are also possible depending on the spatial conditions and requirements for their construction and ffinction. Thus, it is also possible to integrate in a telescopic manner into a first drawer-like unit a further such unit which is preferably used, for exarnple, for accommodating supply systems.
It is also possible to drive out an extension from the roof of the container in order to -form a two level container. In most cases, however, it will be advantageous to push out only a relatively small extension or compartment which will accommodate and protect equipment such as, for example, an air conditioner on the container roof.
Rubber sealing elements can be fitted about the drawer-like units for improved sealing of the container from the outside. The penetration of undesired substances can be prevented more effectively if, in addition to the rubber sealing elements, excess pressure is employed inside the container.
Hydraulic or pneumatic drive devices are preferably provided for the movement of the pivotnble container elements and the drawer elements. Of course, other drive means can be employed, such as spindles, rack and pinion drives, cable or chain drives, and lever systems. ~ -If in the case of a horizontally arranged drawer having a pair of side walls, a pair of top and bottom walls and one front wall the drawer elements are properly sealed to the container, the drawer can be extended by means of an increase in the internal pressure of the container.
If the bearings of a drawer are arranged at a downward slopping angle, the drawer elements can be extended completely, without drive means, simply by the force of their weight.
Slide tracks or roller tracks are preferably provided as guide elements for the drawer, roller tracks having a particularly low friction and being particularly preferred.
Air or magnetic cushion bearings can also be used.
Two preferred exemplary embodiments of the invention are explained ;n greater detail below with reference to the drawings, wherein Figure 1 shows the front view of a container of variable volume according to theinvention, including two retractable drawer-type extension units having a floor, two side walls and a front wall, the roofs of the extensions being respectively formed by a hydraulically pivotable side wall of the container, ~` 211~

Figure 1 shows a main container body 1 two side walls 2 of which can be pivoted using hydraulic actuating means 3. For expansion of the main container 1, the side wall 2 is pivoted upwards until it forms a continuation of the roof 4 of the main container 1 and a drawer-type extension unit is driven out from the main container 1 10 under this roof continuation which then forms the roof of the extension so created. The extension unit has two side walls 5, a front wall 6 and a floor 7. This extension unit is supported by means of a telescopic side rail 8 into which a drive (not shown ) for the drawer-like unit is integrated. After the extension has been extended out from the main container along the slide rail 8, the latter is supported at its outer end point on the lS ground by means of a support element ~ prior to loading of the extension. To compensate for irregularities in the supporting surface, adjustable support elements 9 are provided.
Figure 2 schematically illustrates a container according to the invention, with a ~ -~
plurality of volume expansions. A first extension unit 10, which is a closed drawer with 20 integral roof, is shown extended from a side of the main container body 1. Driven out from a front wall of that unit 10 is a second extension unit 11 of similar construction which is preferably used for accommodating supply systems. A third extension unit 12 is shown extended from the top wall or roof of the main container body 1, which extension is also of similar construction and is preferably used for accommodating 25 further supply systems such as, for example, an air conditioner.
The container according to Figure 3 is similar to the one shown in Figure 1, however, the roof 13 of the extension unit is formed by an element which initially rests on the roof 4 of the main container body 1 in the transport condition and is pivotable through approximately 180 around a top edge of the container wall from which the unit 30 assembly extends. The floor of the drawer-like assembly is formed by a pivotable side wall 14 of the main container body 1 in contrast to the embodiment of Figure 1, wherein the side wall 14 -forms the roof of thc extension.

According to the invention, a container of variable volume is provided which either has a movable extension that is extendible *om the container as a closed drawer-S type unit with a wall portion of the container forming a cover for the drawer or has atleast one essentially enclosed drawer.
In a preferred embodiment, a wall or wall portion of the container body is folded out as a roof for the drawer, and the roof of this drawer is extended out under the roo-f.
In that embodiment, complete projection is provided for the interior of the container, 10 since the end wall of the extension is positioned behind the movable wall or wall portion of the container which functions as a roof for the drawer. In addition, nothing can penetrate into the roo-fless drawer since the latter is extended out under a roof which is already in place.
In another preferred embodiment, not a wall or wall portion of the container is 15 utilized as roof for the drawer but an element which rests on the roof of the container in the transport condition and can be pivoted through approximately 180 about an upper edge of a container wall. The folded out wall or wall portion of the container can then form a side wall of the extension.
In a further preferred embodiment, the extension drawer does not include a floor20 and a wall element which is folded down from a wall of the container is used as the drawer floor. This element can be a wall or wall portion of the container or a wall which is arranged behind one of the container walls.
In yet another preferred embodiment, at least one wall of the container comprises a double sided flap opening, where by the flaps when swung out form opposite walls of 25 the drawer extension in the extended condition.
All these embodiments in accordance with the invention permit partial extension of the drawer and, thus, a continuous variation of the container volurne. This permits a better adaptation of the expandable container to the external installation conditions on site. The embodiments according to the invention also permit variation of the container 30 volume while the container is kept closed off from the exterior in order to prevent the penetration of the external atmosphere and undesired substances.
