A frame section for producing a backlit false wall and a backlit false wall, having a section body of tubular shape comprising a peripheral wall, a first and a second longitudinal cavity that each have an opening onto the peripheral wall, the first cavity comprising means for attaching at least one canvas, the second cavity accommodating lighting means, wherein the second cavity has an end wall bordered by two diverging cavity walls that delimit the opening of the second cavity.

A hanging system for a stretch false ceiling comprises a fastening profile suitable for being fastened to a wall and having at least one air-flow opening, a rail arranged for hanging at least one stretched piece of fabric and suitable for being securely mounted on the fastening profile, and blocking means for holding the rail in position on the fastening profile when the rail is mounted on the profile. The fastening profile and the rail respectively have, protruding from the wall, reciprocal mating means making it possible to assemble the rail and the fastening profile by insertion of the means into each other. The blocking means have at least one element forming a bolster that is disposed between the fastening profile and the rail.

An improved greenhouse structure having sides and a roof to define at least a partially enclosed space, with an interior ceiling section and the interior ceiling section being at least substantially transparent. An air channel is formed between the roof and the interior ceiling section with an air input device in fluid communication with the air channel and the interior ceiling section has one or more openings through it to allow air in the air channel to pass through and into the enclosed growing space to provide a top-down air conditioned effect.

The present disclosure relates to a false ceiling and an installation comprising such a structure for feeding treated air into a room, comprising a ceiling wall, a false wall positioned on the underside of, and at a distance from, all or a portion of the ceiling wall and defining, with the ceiling wall or a portion of the ceiling wall, an airflow corridor that is referred to as a plenum and comprises an air outlet opening inside the room provided in the false wall, characterized in that the false ceiling comprises lighting means comprising a plurality of light sources that are capable of emitting ultraviolet light and arranged in the airflow corridor so as to sterilize the air flowing in the corridor before it passes through the air outlet slot.

A fabric panel attaching system and methods of assembly and use are presented for attaching fabric panels to structural elements, such as building frames. In various embodiments, the fabric panel attachment system includes a keder rail fastened to support bar, which is attached to a structural profile, such as a building frame member. In some embodiments, the keder rail is fastened to a support bar with bolt and nut. One or more fabric panels are installed within channels of the keder rail. An alignment element may be used with a fastener to assist in aligning abutting sections of keder rail. In various embodiments, the fabric panel attachment system is secured to flat or curvilinear faces of the structural elements. In some embodiments, the fabric panel attachment system may secure directly to the structural element and not a support bar.

The panel includes a frame formed by profile members (6) and a plate member (10) extending therebetween. A textile (11) extends between the profile members which are formed by bending an edge area of a metal plate (15) forming the plate member (10), thereby forming said profile members in one piece with the plate member. Said edge area forms a rounded edge (16) connecting the plate member with the profile member. The profile member includes a first oblique section (21) of the metal plate forming an acute angle with the plate member and having a first end being connected to the rounded edge. The textile is bent about the rounded edge, and an edge element (24) attached along an edge (12) of the textile is adapted to slide along the first oblique section and is spring-biased in the direction of a second end (23) of the first oblique section.

A canvas hanger profile for making a stretched ceiling in a room to be conditioned, the hanger profile comprising at least two wings connected together by a connecting lining, one of the wings being arranged to allow the fastening of the hanger profile on a wall of the room to be conditioned, a second wing, which constitutes a canvas hanger wing, being provided with a blocking end of a canvas hook, wherein the connecting lining and the hanger wing are arranged to define together an unclosed air passage slot through the profile and are delimited by the blocking end of the hanger wing hook, the profile having at least one through opening arranged to allow air to pass through said profile from or towards the slot.

The fabric mounting system (1) includes a mounting profile (4) adapted to be mounted to a wall or ceiling and at least one fabric retaining element (5) engaging the mounting profile and being adapted to retain an edge (6) of the fabric (2). First and second supporting faces (9, 10) of the mounting profile (4) are mutually tapered in such a tapering direction (T) that a resilient bias of first and second legs (7, 8) of the fabric retaining element (5) urges the first and second legs (7, 8) to slide along the first and the second supporting faces (9, 10), respectively, to thereby displace the fabric retaining element in a direction generally against the tapering direction (T) and in a fabric tensioning direction (F) being transverse to a longitudinal direction (L) of the mounting profile (4) in order to stretch the fabric (2) in its retained position.

A mounting frame (100) which can be attached to a ceiling (3) and comprises an assembly of basic profiles (10) comprising a housing (14) for receiving an edge of a covering (1) and a plurality of V-shaped or U-shaped locking clips (50) designed to enter the receiving housing (14) and remain therein in a locked position in which the edge of the covering (1) is clamped between the locking clip (50) and the housing (14). Each locking clip (50) is interposed between an insertion tool and the covering (1) and facilitates the insertion of the covering (1) into the receiving housing (14) without damaging the covering (1). The covering (1), with dimensions greater than those of the frame, can thus be completely removed and reused since the covering has not been damaged in any way, either while the covering (1) is being fitted or while being held in place.

A beam profile member intended for being secured to a wall and arranged to allow the fastening of a tensioned fabric in order to produce a false wall, the beam profile member including a flange for securing to the wall having an inside face and an outside face, characterised in that the outside face of the securing flange is provided with at least one resiliently deformable zone arranged to absorb the deformation of the securing flange generated by the pushing force applied to the inside face of the securing flange during the operation to secure the beam profile member to the wall.
