DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a collapsible dwelling, the sidewalls of which can occupy an opened-out position and a collapsed position, its purpose being especially to provide a dwelling whose structure is simple to manufacture and which is particularly simple to collapse and to open out.
A tent frame is known, from Patent FR-A-2, 118,058, which comprises four uprights whose top ends are connected via a X-shaped structure, it being possible to collapse this frame by lowering the central part of the X-shaped structure, thus causing the uprights to move close together in parallel towards the center, and conversely for opening it out.
Tents are also known which open out and collapse in the manner of concertinas. Such tents are described in Patents GB-A-976,912, U.S. Pat. No. 3,373,671, GB-A-889,455, GB-A-1,600,242 and U.S. Pat. No. 4,066,089.
A collapsible tent is known, from Patent U.S. Pat. No. 4,825,891, which comprises two U-shaped opposing frames, the ends of which can be pushed into the ground, this tent collapsing by bringing the two frames side by side.
A collapsible tent is also known, from Patent B GB-A-2,204,337, which comprises three U-shaped frames, which the ends of their corresponding branches are connected in an articulated manner, this tent collapsing by pivotally moving its frames close together.
A collapsible dwelling, in which the roof is separable from the sidewalls, is known, moreover, from tent WO-A-8,603,243.
The present invention provides a collapsible dwelling of a completely different design from those described especially in the aforementioned documents, especially as regards its method of folding or unfolding.
Another object of the present invention is to provide a collapsible dwelling whose ratio of volume in the open-out position to that in the collapsed position is particularly large.
The collapsible dwelling according to the invention comprises a base (2), at least two opposite sidewalls (3, 4) connected in an articulated manner to said base and which can be inwardly folded down one over the other, and a roof (7), which is connected to the top part of said opposite sidewalls (3, 4). The roof continuously connects the opposite sidewalls so that, during the collapsing of the dwelling, the roof is turned over, such that, in the collapsed position, the roof lies between said opposite sidewalls.
Thus, in the collapsed position, the topside of the roof can lie facing the outside of one of said sidewalls, its underside lying facing the inside of the other sidewall.
In a variant of the invention, the roof is rigid and is connected in an articulated manner to said sidewalls.
In another variant, the roof can be formed by a sheet connected to said opposite sidewalls.
In a preferred embodiment, said sidewalls comprise a peripheral frame, a sheet having two portions respectively fastened to said frames of said sidewalls and, between these two portions, a central portion forming said roof.
Said frees can advantageously be U-shaped, of which the ends of their opposite branches forming uprights are articulated to said base and of which their central branch forming a cross-piece lies underneath and carries said sheet.
The dwelling according to the invention can furthermore comprise at least one other sidewall whose top edge lies along a free edge of the roof, the latter being equipped with a flap covering the top part of the outside of this other sidewall, this other sidewall being connected to said base and being able to be inwardly folded down.
Preferably, said opposite sidewalls can be equipped with flaps covering the edges of the outside of said other sidewall.
Said flaps can be formed by extensions of said sheet.
Furthermore, said flaps and the outside of said other sidewall are preferably equipped with detachable fastening means.
In a preferred variant, said other wall comprises a top part and a bottom part which are articulated such that the top part can be folded down over the bottom part.
According to an advantageous embodiment, said bottom part comprises a U-shaped frame, the end
