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 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.

A removable panel is provided. The removable panel including a fixed section including a metal fixed section frame, an opening section including a metal opening section frame able to be reversibly nested in the fixed section, at least one magnet that makes it possible to maintain the opening section nested in the fixed section, at least one sling fastened to the fixed section at a first end and reversibly fastened to the opening section at a second end. The removable panel includes at least one safety device able to ensure the fastening of the at least one sling to the opening section. A suspended ceiling that integrates a removable panel is also provided.

The present invention relates to an easily assembled and disassembled shade-providing structure, such as may be mounted to a playground assembly. The shade-providing structure comprises an outer frame defining an interior space and a canopy that may be positioned in that interior space. The canopy has one or more rods around its periphery, such as may be inserted through one or more pockets in the canopy fabric. Each of the outer frame and the rod(s) has a set of apertures configured to receive a locking fastener and a set of apertures configured to receive a jack screw or similar tensioning device. Accordingly, to assembly the structure, one or more jack screws can be used to provide the canopy with a desired tension and then locking fasteners can be used to secure the canopy to the outer frame.

A ceiling panel according to the present invention has opposed translucent membranes secured in a tensioned state across a perimeter frame. The frame includes frame members that are designed to oppose inward bowing of the perimeter frame caused by the tensioned membranes. The frame members have a side profile shaped to conceal a grid support network with the lower translucent member extending across and about a lower edge of the perimeter frame. The invention also includes a modified structure for supporting of translucent panels below a grid network.

A stretched-web structure for producing a false ceiling or a dropped ceiling box in a room, including two flexible webs arranged parallel to one another and fastened stretched between at least one wall, wherein one of the webs is made of polyvinyl chloride and the other web is made of fabric.

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 false ceiling comprising a bearing structure comprising at least two coplanar and mutually parallel opposite profile members fixed to a ceiling, the profile members between them defining an access opening providing access to the ceiling, each profile member comprising a shoulder defining a horizontal bearing surface facing towards the ceiling, at least one panel positioned between the profile members, the panel being dimensioned to rest on the bearing surface of the profile members, the false ceiling further comprising removable and attached wedging means for transversely wedging the panel between two opposite profile members, the wedging means being arranged on either side of the panel.

The present invention relates to an easily assembled and disassembled shade-providing structure, such as may be mounted to a playground assembly. The shade-providing structure comprises an outer frame defining an interior space and a canopy that may be positioned in that interior space. The canopy has one or more rods around its periphery, such as may be inserted through one or more pockets in the canopy fabric. Each of the outer frame and the rod(s) has a set of apertures configured to receive a locking fastener and a set of apertures configured to receive a jack screw or similar tensioning device. Accordingly, to assembly the structure, one or more jack screws can be used to provide the canopy with a desired tension and then locking fasteners can be used to secure the canopy to the outer frame.
