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 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.

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.

An odour neutralising structure comprising a wall rail section arranged to hang a stretched fabric in order to produce a false wall and at least one filter cartridge containing a sorbent material that can absorb one or more specific odour(s), said cartridge being housed in a groove in the wall rail section.

An example of conversion of solar energy into other forms of useful energy is taking heat from an area below a roof and using the heat to generate mechanical energy or electrical power. An air duct opening is placed in a hottest area under the roof. An air fan is placed in the air duct to draw the heated air from the area below the roof. A heat exchanger coil is placed inside the air duct. A return air duct is routed back to the area below the roof. The heat exchanger coil is coupled to a turbine through a closed loop line. A heat transfer medium pump, a first valve and a second valve are retained in the closed loop line. The first valve, second valve and pump are used regulate heat transfer medium into and out of the turbine. An electrical generator may be connected to the turbine.

A fabric housing, a method of installing a fabric housing, and a method of manufacturing a fabric housing are provided. The fabric housing for stretching fabric on walls or ceilings includes a first exterior wall. The fabric housing also includes a second exterior wall. The fabric housing further includes a tensioning leg configured to tightly abut one of the first exterior wall or second exterior wall. The tensioning leg is configured to grip a fabric between the tensioning leg and the one of the first exterior wall or second exterior wall. The fabric housing still further includes a pair of opposing jaws configured to secure the fabric. The pair of opposing jaws are disposed along one of the first exterior wall or the second exterior wall. A corresponding method of manufacturing a fabric housing and installing a fabric housing are provided herein.

A device for attaching flexible, flat fabrics includes at least one keder rail having a keder channel in which a keder core attached to the fabric is inserted. The device includes at least one receiving profile in or on which the at least one keder rail is arranged relocatable at an adjustable height.

The invention relates to a device for re-cladding a removable panel comprising an outer face, an inner face situated on the opposite side to the outer face, and a peripheral edge joining the outer and inner faces, said re-cladding device is notable in that it comprises at least two cladding sections the vertical cross section of which is in the overall shape of a C and which are fixed facing one another along two respective opposing regions of said peripheral edge, and a fabric is kept stretched along the outer face of the removable panel by said cladding sections.

An expander member for use with fastening track for fabric wall coverings that allows for wider distances between the fabric and the wall to be covered. The invention allows for top loading of fabric as well as side loading. The expander includes a series of grooves that allow for fastening of the member to a wall as well as for fastening to additional members proximate the top and bottom as desired. Alternatively, one or more pocket holes can be used to secure the member to a wall using a fastening screw. In the preferred embodiment first flange extends outward from the member with a height shorter than the member forming a groove therebetween for the placement therein of the fastening track. An alternate embodiment includes a second top flange that is proximate the top side and the back that has a length shorter than the top side creating a groove therebetween for the placement therein of a second fastening track that allow for fabric to horizontally stretch atop the member a desired.

A ceiling system including: a ceiling structure suspended in an interior space. The ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame comprising a fabric gripping member; a support grid comprising a plurality of intersecting struts defining a plurality of grid openings, the support grid disposed within the central opening and coupled to the perimeter frame; a plurality of acoustic ceiling panels, each of the acoustic ceiling panels mounted to the support grid and disposed in one of the grid openings; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric sheet located below the acoustic ceiling panels and covering the central opening.
