BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a rigid construction which offers an extendible internal space and which, if required, can be moved in the form of a trailer or semitrailer or be transported in the form of a container.
Activities in various fields such as culture, sport, medicine, civil defense and education sometimes require the temporary use of a confined space offering a useful volume that is adequate and in any case greater than would be provided by a bus, a coach, a semitrailer or a container for example. Examples which may be cited are a mobile medical clinic, a mobile command centre, a travelling cinema, a travelling exhibition room, a mobile dispensary and the like.
In the present state of the art, the requisite useful spaces can be produced by erecting constructions of flexible material, for example a tent, or by erecting constructions of rigid material, for example huts, single-storey constructions, containers and the like. The erection of constructions of this kind necessitates numerous handling operations and does not quickly offer the final space required for the desired use.
To extend the useful space requires an amount of manpower which may be considerable (for example pitching a tent), the execution of preparatory construction work (for example casting a solid bed or plinths beneath huts) or many often difficult handling operations (for example assembling and adjusting containers).
SUMMARY OF THE INVENTION
The object of the present invention is to respond to this need of the market by providing a rigid construction which, starting from an initial space imposed by the particular conditions, for example a transport regulation (size of an ordinary container or load), enables a larger useful space to be created rapidly while requiring the work of only one person.
In accordance with the invention, there is provided a rigid construction notable in that it comprises a first fixed box and at least one second box surrounding the fixed box, the second box being mounted so as to be able to slide transversely to an axis of the fixed box in order to extend the internal volume of the construction.
In an illustrative non-limiting embodiment, the fixed box is carried by a plurality of fixed crossbars and the second box is mounted on a plurality of sliding crossbars which are mounted to slide along the fixed crossbars.
A preferred embodiment comprises sliding crossbars which are mounted to slide inside hallow fixed crossbars and they slide on rolling means.
Advantageously, the sliding crossbars roll with the aid of rollers on retractable rolling crossbars.
In a particular embodiment, the sliding crossbars carry brackets (22) serving as a support for the casing of the movable box.
On the interior face of the roof of the sliding box are advantageously a plurality of sliding channels for the suspension of rollers integral with the fixed roof of the box.
The casing of the second box can be formed with support means which are an integral part of the casing. It could also be self-supporting.
The floors of the fixed box and sliding box(es) can be mounted in various ways. For example, the floor which is integral with the fixed structure can be mounted on lifting means arranged to raise the said floor when the second box or boxes are retracted 96 that the floor of the or of each second box can be accommodated beneath it. The floor of the or of each second box can also be articulated to the structure of the said box so as to be able to be raised by pivoting when the sliding box is in the retracted position. Also only a part of the floor of each sliding box may be articulated. The floors may advantageously be mounted over vibration damping devices.
The constructions according to the invention can be put in place and opened out without the need for qualified staff and without the use of expensive or non-standardized materials or components. What is more, the constructions of the invention can be put in place equally well in normal environmental conditions and in hostile conditions (very
