Element as defined in either one of claim 1 or 2, in which the frame is comprised of at least two parts so arranged as to be slidable relative to one another along said direction in substantial parallel relationship with the element thickness, to lie in two end positions, the one position in which the panel is received within the frame thickness and another position in which the panel projects from said frame on either side thereof.

Claim 9

Element as defined in claim 7, in which the frame is comprised of a first framework formed by a U-shaped section the flanges of which face the panel and extend at right angle to the panel thickness, and of a second framework formed by an angle part the one flange of which bears on the U-profile web while the other flange extends at right angle to the panel thickness and faces said panel, the panel being provided along the edges thereof and facing the frame with a projection to which are made fast the connecting means, said connecting means being comprised on the one hand of an angle part the one flange of which is fastened to the projection in parallel relationship with the U-profile flanges, while the other flange bears on the U-profile web opposite the flange of said frame angle part, and on the other hand by screw-bolts the nut of which is fastened to the flange of that angle part made fast to the projection and the shaft of which passes through openings provided in said angle part as well as in the web of said U-profile and in the flange of that frame angle part which cooperates with said profile, the projection and the connecting means being moreover so arranged as to let the flanges of the U-profile and the flange of the frame angle part in parallel relationship with the profile flanges fit on either side of the projection within the panel thickness.

Claim 10

Element as defined in either one of claim 1 or 2, in which the frame, the panel and the connecting means provided between the frame and the panel are so arranged as to let the panel move substantially in parallel relationship with itself and the frame, to lie in two end positions, the one position in which the panel is received within the frame thickness and another position in which the panel projects relative to said frame.

Claim 11

Element as defined in claim 9, which comprises two closing panels arranged in parallel relationship in the frame, said connecting means being so arranged as to let the closing panels move relative to the frame and in parallel relationship with one another along opposite directions, either to be received within the frame thickness, or to project relative to said frame on either side thereof.

Claim 12

Element as defined in claim 10, in which an insulating element is provided between both closing panels of said frame.

Claim 13

An assembly of elements each of which is as defined in claim 1, said elements being joined and hinged to one another to let same swing relative to one another about an axis in parallel relationship with one element edge, to fold the sections concertina-like on one another.

Claim 14

An assembly as defined in claim 12, which comprises a structure comprised of four elements in the shape of a quadrilateral with four right angles, the end elements of the assembly having to form either the double-ceiling of the building or the side walls thereof, while the two other elements comprise the roof sides, the element hinges being so arranged as to let in folded position, the outer surfaces of those elements comprising the roof sides contact one another while the end elements the sizes of which are smaller than the sizes of those elements comprising the roof sides, fit therein.

Claim 15

An assembly as defined in claim 12, which comprises assembly means allowing to join the assembly to the building foundation.

Claim 16

An assembly as defined in claim 12, which comprises a structure formed by four of said elements in the shape of quadrilateral with four right angles, the end elements of the assembly having to form either the side walls of the building or the double-ceiling thereof, while the two other elements comprise the roof sides, the elements being hinged in such a way that in folded position, the outer surfaces of those elements forming the roof sides contact one another while the inner surfaces of said elements engage the inner surface of those elements comprising the side walls or the double-ceiling of the building, the sizes of the various elements as considered in parallel relationship with the hinge axis being the same, while the sizes of the elements as considered at right angle to the hinge axis are the same by pair

Claim 17

An assembly as defined in claim 15, which comprises two intermediate elements, each intermediate element being hinged on one end element.

Claim 18

An assembly as defined in claim 15, which comprises two intermediate elements, each intermediate element being hinged on an element comprising one roof side, the hinge axes of said intermediate elements being in parallel relationship and at the same spacing from the hinge axis of those elements forming the roof sides, said intermediate elements having the same size, the dimension thereof as considered in parallel relationship with the hinge axis being shorter than the corresponding dimension of the other elements while the dimension thereof as considered at right angle to the hinge axis is shorter than the spacing between the hinge axis of an intermediate element and the frame edge of the corresponding roof side-forming element nearest the hinge axis of those elements forming said roof sides, each such intermediate element comprising a frame and at least one closing panel as well as connecting means between the frame and the panel, said connecting means being so arranged as to let said panel move between said two end positions, the hinges of the intermediate elements and said end elements being so arranged as to let in the folded assembly position, the intermediate elements fold back on the inner surfaces of those elements comprising the roof sides and fit within said end elements when the inner surfaces thereof engage the inner surfaces of those elements comprising the roof sides.

Claim 19

An assembly as defined in claim 15, which comprises two intermediate elements, each intermediate element being hinged on an element comprising one roof side, the hinge axis of said intermediate elements being in parallel relationship and at the same spacing from the hinge axis of those elements forming the roof sides, said intermediate elements having the same size, the dimension thereof as considered in parallel relationship with the hinge axis, being shorter than the corresponding dimension of the other elements, while the dimension thereof as considered at right angle to the hinge axis, is shorter than the spacing between the hinge axis of an intermediate element from the corresponding roof side-forming element frame nearest and in parallel relationship with the hinge axis of those elements forming said roof sides, the hinges of the intermediate sections, each intermediate element comprising a frame and at least one closing panel as well as connecting means between the frame and the panel, so arranged as to let the panel move between said two end positions, being so arranged as to let in folded position, said intermediate elements fit within those elements comprising the roof sides, the hinges of said latter elements and of said end elements being so arranged as to let the inner surfaces of the end elements engage the inner surfaces of the roof side-forming elements.
