Modular shelter

Abstract

A modular shelter designed to partially or totally cover a ground area comprises a plurality of nested modules assembled with telescopic fitting by rotation around one and the same vertical axis, so as to vary between an extended position where the whole of said area is covered and a retracted position wherein all of the modules are housed in the module having the largest dimensions. Each module has a roof and a substantially vertical side wall. Each module comprises a rigid structure supporting filling panels and composed: of a parallel and horizontal bottom arch and top arch, of a plurality of uprights that extend between said bottom and top arches, of radial cross-members converging towards said vertical axis from the top arch.

1 . Modular shelter designed to partially or totally cover a ground area, comprising a plurality of nested modules assembled with telescopic fitting by rotation around one and the same vertical axis, so as to vary between an extended position where the whole of said area is covered and a retracted position wherein all of the modules are housed in the module having the largest dimensions, each module having a roof and a substantially vertical side wall, wherein each module comprises a rigid structure supporting filling panels and composed: 
 of a parallel and horizontal bottom arch and top arch,    of a plurality of uprights that extend between said bottom and top arches,    of radial cross-members converging towards said vertical axis from the top arch.    
   
   
       2 . Shelter according to  claim 1 , wherein the cross-members of one of the modules support a vertical shaft, at their free end, said shaft being situated at a distance from the ground and coinciding with the axis of rotation of the modules, the free ends of the cross-members of the other modules being mounted rotating freely on said shaft.  
   
   
       3 . Shelter according to  claim 1 , wherein each filling panel of the roof of the modules is a portion of surface of revolution the axis whereof coincides with the axis of rotation of the modules, and the generating line whereof is a substantially horizontal straight line.  
   
   
       4 . Shelter according to  claim 1 , wherein each filling panel of the side wall of the modules is a portion of surface of revolution the axis whereof coincides with the axis of rotation of the modules, and the generating line whereof is a substantially vertical straight line.  
   
   
       5 . Shelter according to  claim 1 , wherein the module having the largest dimensions is fixed with respect to the ground and defines an angular sector of more than 90° in a plane perpendicular to the axis of rotation of the modules.  
   
   
       6 . Shelter according to  claim 1 , wherein each movable module is mounted sliding along a respective slide arranged on the ground and centered on the axis of rotation of the modules.  
   
   
       7 . Shelter according to  claim 1 , wherein the filling panels of the roof of at least one module are made from a thermally insulating material.  
   
   
       8 . Shelter according to  claim 1 , wherein at least one filling panel of the side wall of at least one module is made from a transparent or translucent material.
