DESCRIPTION:
BRIEF SUMMARY
The invention relates to an extensible construction.
Extensible constructions designed to be reduced in volume for transport and extended for use at their place of destination have been known in various forms for a long time. They have, however, now become increasingly important due to the natural disasters which have occurred more and more frequently in recent years and which require convenient transport and rapid installation of hospitals and other emergency medical stations, stores, workshops, etc. EP-A-0 109 108 discloses a construction of the type described in the first paragraph of the present specification. This known construction consists of an extensible shed or canopy comprising a set of gentry-like trestles or portals with wheels at their base designed to roll on rails previously placed in the ground so that the trestles or portals can be moved away from each other to stretch out the shed or canopy or brought closer together to fold it up. These trestles or portals have side walls and panels serving as ceilings hinged to them.
The side walls and ceiling panels of the shed or canopy described in the above mentioned document extend to the outside of the trestles or portals when the latter are brought close together so that the height and width of the shed or canopy are greater when the construction is folded up than when it is stretched out.
Moreover, the said shed or canopy has no elements to form a floor and is not equipped with any means for subdividing it into separate space units when it is stretched out.
Other constructions are known which are designed to be transported on wheels and are in particular in the form of trailers provided with means for increasing their volume when installed.
BRIEF DESCRIPTION OF THE INVENTION
The present invention has as its object a horizontally extensive construction which can easily be transported, preferably in a box or container by rapid, modern transport means, in particular by air.
The invention also has as its object an extensible construction which has the same height and width when stretched out as when folded up and which has not only side walls and a ceiling but also a floor.
The invention further relates to an extensible construction which can be rapidly extended without requiring special means or particular skill.
According to the present invention, the extensible construction of the type described in the first paragraph of this specification is basically characterised in that the said prefabricated elements have the form of vertical rectangular frames composed of two uprights connected together by an upper crossbeam and a lower crossbeam, and the connecting members between these frames consist of panels designed to form a floor, a ceiling and optionally side walls of the construction when the construction is extended, the said panels being accommodated in the space bounded by two successive frames when the said frames have been brought close together so that the construction is in its compact state.
In one particularly advantageous embodiment, the extensible construction according to the invention comprises a transportable box capable of containing the aforesaid frames and panels which are enclosed therein when the construction is in its compact state.
The frames and the panels articulated thereto preferably form a superstructure which rests against an infrastructure before, during and after the said frames and panels are moved closer together or stretched out, which infrastructure consists of a system of beams hinged to one another and advantageously forming horizontal rails when stretched out so that rollers mounted on the lower crossbeam of the various frames can roll on these rails.
In one particular embodiment of the construction according to the invention, a panel designed to form the floor of a space unit formed between two frames when these are spaced apart is hinged at its lower edge to the lower crossbeam of the first of these two frames while at the ends of its opposite edge it has rollers capable of rotating freely about shafts para
