Elements of stretched false ceiling, use of same for producing false walls and false ceilings

A false partition element comprising:

• a frame comprising at least one profile, each profile having an attachment projection and a lateral edge, the lateral edge of at least one profile being curved along at least a portion thereof;
• and
• a fabric stretched inside the frame, at least one edge of the fabric having an attachment element co-operating with the attachment projection to attach the fabric to the profile, wherein a visible portion of the stretched fabric has a shape defined at least in part by the curve of the lateral edge of the profile;
• wherein the profile includes a main wall having a plurality of extensions oriented inward of the profile, said plurality of extensions comprising:
• an upper extreme sole,
• a first L-shaped projection, when seen as a cross section, the first L-shaped projection forming, with the main wall, a first support groove with an opening oriented towards the upper extreme sole,
• a second projection approximately perpendicular to the main wall,
• a third L-shaped projection, when viewed as a cross section, the fourth
• a fourth T-shaped projection, when viewed as a cross section, the fourth projection comprising a first wall approximately perpendicular to the main wall and a second wall approximately parallel to the main wall, and
• the attachment projection.

A false partition element comprising:

• a frame comprising at least one profile, each profile having an attachment projection and a lateral edge, the lateral edge of at least one profile being curved along at least a portion thereof;
• and
• a fabric stretched inside the frame, at least one edge of the fabric having an attachment element co-operating with the attachment projection to attach the fabric to the profile, wherein a visible portion of the stretched fabric has a shape defined at least in part by the curve of the lateral edge of the profile;
• and
• wherein:
• said frame further comprises a plurality of rails mounted approximately perpendicular to the profiles;
• said frame further comprises a plurality of side rails, the rails and side rails forming a trellis;
• said rails define openings passed through by said side rails;
• the profile includes a main wall having a plurality of projections oriented inward of the main wall;
• the rails extend up to a height less than a height of the profile, whereby the rails and side rails are hidden from view by the profile;
• said frame further comprises a stiffening element attached to at least one of the plurality of rails and to an upper extremity side of the profile, said stiffening element being slanted with respect to plane of the fabric and chosen from the group, comprising beams, struts, turnbuckles and tightening trundles.

A false partition element comprising:

• a frame comprising at least one profile, each profile having an attachment projection and a lateral edge, the lateral edge of at least one profile being curved along at least a portion thereof;
• and
• a fabric stretched inside the frame, at least one edge of the fabric having an attachment element co-operating with the attachment projection to attach the fabric to the profile, wherein a visible portion of the stretched fabric has a shape defined at least in part by the curve of the lateral edge of the profile;
• and
• wherein:
• the profile includes a main wall having a plurality of projections oriented inward of said main wall, said plurality of projections comprising:
• an upper extreme sole,
• a first L-shaped projection, when seen as a cross section, the first L-shaped projection forming, with the main wall, a first support groove with an opening orientated towards the upper extreme sole,
• a second projection approximately perpendicular to the main wall,
• a third L-shaped projection, when viewed as a cross section,
• a fourth T-shaped projection, when viewed as a cross section, the fourth projection comprising a first wall approximately perpendicular to the main wall and a second wall approximately parallel to the main wall,
• the attachment projection,
• said upper extreme sole comprises a projection approximately parallel to the main wall and spaced apart from the main wall by a first distance, thereby defining a first housing to slideably accept a first profile plate whose thickness is less than or equal to the first distance between the upper extreme sole and the first support groove;
• the first wall of the fourth projection includes a rib spaced apart from the main wall by a second distance approximately equal to a size of an opening of a second support groove defined by the third projection, thereby defining a second housing to slideably accept a second profile plate whose thickness is less than or equal to the second distance;
• a height of the first housing approximately equals a height of the second housing;
• further comprising first and second profile plates respectively introduced into the first and second housings, wherein at least one of the first and second profile plates has an external face that marries a shape of an internal face of the profile and at least one threaded hole, each threaded hole being fitted with a screw for locking the profile plate to the profile;
• further comprising a plurality of rails mounted approximately perpendicular to the profile;
• further comprising a plurality of rail supports, each comprising:
• a main plate whose external face marries a shape of an internal face between the third projection and the rib, and
• a bracket extending approximately perpendicular to the main plate and attached to at least one of the plurality of rails.
