Definitions

• the invention relates to a variable-sized space element which, when unfolded, provides a large usable volume, folded together, e.g. for transport purposes, but only requires a small volume.
• the invention has for its object to provide a resizable space element according to the preamble of the main claim, which allows a variation of the volume in a wide range and has high strength and good insulation properties.
• the floor and the ceiling which are designed as plate-shaped elements in the invention, are connected by means of further plate-shaped elements via lockable hinges and thus have high strength and good insulation properties.
• lockable hinges which can be designed in the manner of the hinges described in the documents of DE-GM 89 09 950.8, and on the other hand in the use of lightweight or composite materials.
• the combined use of the linear expansion by means of the telescopic adjusting device and the use of the hinges mean that the range of the volume variation is a multiple of what was previously used. Also, the space that the folded resizable space element occupies is only a fraction of that
• drive units for linear and / or radial drive movements can advantageously be provided in a further embodiment of the invention.
• These drive units can be controlled by a controller so that a synchronous movement of all plate-shaped elements is possible.
• it is also possible to move individual plate-shaped elements for example manually, for example to make readjustments.
• plate-shaped elements it may be useful to reduce the weight in a covering construction or to combine it with covering structures, e.g. Save weight.
• Roller blind-like walls can also be used.
• the resizable room elements according to the invention can not only be used in the field of camping and caravan construction, they can also be used for other purposes in the field of mobile living. For example, it could be used as a garden, hunting or shelter. Use as a combination with travel buses or cruising yachts would also be conceivable.

• FIG. 1 shows a first embodiment of the variable-size space element according to the invention, on the bottom 10 of which a plate-shaped element 20 designed as a flat surface element is arranged.
• plate-shaped elements 24a, 25a which are designed as angle elements, are fastened via lockable hinges 30a, 30b.
• This Angle elements are L-shaped in cross section and have second lockable hinges 34, 35 which are arranged at the free end of the leg of the angle element which does not connect to the plate-shaped element 20 on the floor.
• the second lockable hinges are connected, in mirror image to a plane through the second hinges, by plate-shaped elements 24b, 25b, which are designed as angle elements, and in turn by a plate-shaped element 21, which is designed as a flat surface element, and one Part of the ceiling 1 1 forms.
• the resizable space element 1 has a

• FIG. 2. 2 is the
• Telescopic device 51 for the sides and extendable twice for the floor and the ceiling.
• these telescopic adjustment devices which are shown in FIG. 3 as being simply extendable, the
• Cross-sectional area of the spatial element the area of the plate-shaped elements in plan view and thus also the volume of the spatial element increases when the telescopic adjustment devices 50, 51 are extended.
• Third drive units 55, 57, which move the telescopic adjustment device 50, 51, are provided as drive means.

• 5 Another embodiment of the variable-sized space element is designed with plate-shaped elements on the sides, which are designed as angle elements, have only little remaining space in the folded state. 4 and 5 show two states, namely the state folded up and the state during unfolding. It can be seen that the second hinges 34, 35 are moved into the middle of the room by the folding process and at the same time the first hinges 30a, 30b, 31a, 31b become side edges of the folded spatial element by this process.

• Installation parts 60 to 65 can be installed in a size-changing spatial element according to the invention, as shown in FIG. 7. These built-in parts form the device and, when folded, find space in the remaining space 79, which is shown in FIG. 2.
• the remaining space depends on the length of the legs of the angle elements, which adjoin the plate-shaped element of the ceiling or floor, if such angle elements are arranged on the sides. The longer these legs are, the more space remains when folded.
