A louver roof system having a simplified assembly and installation methods. The louver roof system is constructed with multi-functional mechanical components by means of pre-molded parts to reduce skilled installation time. Water drainage path is an integral part of the main structural assembly.

A multi-function leaf-separating-discharging height-and-angle-adjustable louvered pergola comprises: opposing end caps, multi-screen-securing edges, rainwater-and-wind-sealing insulation strips attached to multi-screen-securing louver blades for automatically raising and lowering shade and video projection screens and controlling fruit-drying duration and also functioning as a truck-bed tonneau cover, cradle axels inserted between cradle caps and rotation cradles, stanchions and rotation cradles screwed to first and second leaf-discharging side gutter beams, corner posts, multi-louver-control bar connected to linkage arm, linkage arm connected to worm-gear transmission controlled by multi-screen-raising-lowering multi-louver-control crank, first and second rainwater-channeling-and-leaf-filtering side gutter beams attached to the corner posts, the discrete-leaf-filtering tubes, spouts, corner-post base plates, and height-and-angle-adjustable tube screws screwed into the corner-post base plates.

A system for creating an enclosed room, such as an office, in an open space that has a floor and a ceiling. The system includes a support frame that is self-supported on the floor of the open space. The support frame includes a series of head rails supported by a series of vertical columns resting on the floor. The vertical columns support a series of wall panels and the head rails support a ceiling such that the ceiling is supported by the support frame independent of the wall panels. The ceiling of the enclosed room is created by a series of ceiling panels and at least one air intake panel and at least one air exhaust panel. The air exhaust panel includes an exhaust fan that removes air from within the enclosed room and draws fresh air into the enclosed room. The ceiling can include a plurality of adjustable louvers and lighting.

A modular building section defining the roof and opposing walls of a modular clearspan building. The building section includes a roof portion extending in a longitudinal direction between opposite first and second ends, and a pair of first and second legs, each leg pivotally attached about a pivot axis to the roof portion proximate a roof portion end. Each of the first and second legs has a stowed position in which the leg generally extends in the longitudinal direction and is in superposition with the roof portion, and an expanded position in which the leg depends from the roof portion and generally extends perpendicularly to the longitudinal direction. The legs are moveable independently of each other from their respective stowed positions to their respective expanded positions under the influence of gravity during lifting of the roof portion. Also disclosed are methods for constructing a modular clearspan building.

A process for conditioning the air within a greenhouse comprising transparent walls and a structure including one or more ridge beams as part of a roof of the greenhouse. The process comprises maintaining a pressure difference between an average pressure within the greenhouse and a pressure exterior to the greenhouse, taking in air from the exterior of the greenhouse and mixing this air with air taken from the interior of the greenhouse to obtain conditioned air, distributing the conditioned air via a forced flow to the interior of the greenhouse, and discharging a volume of air from the interior of the greenhouse via openings present in the one or more ridge beams such to maintain the pressure difference.

A pressure-sensitive relief panel for screened enclosures of swimming pools, spas or patios is disclosed. By securing the panels with a pressure release system the structure and panels can remain intact year round. If a weather event occurs either with or without warning the panels will automatically provide relief from loads or forces imposed by the event that could cause damage or even collapse of the structure.

Embodiments of the present invention are directed to shelter assemblies for bicycles that can be custom designed in a variety of configurations using a relatively small number of modular, easily assembled components. The shelter assembly comprises at least first and second uprights, a crossbar bridging the first and second uprights, and a plurality of roof panels secured to the crossbar. Each roof panel is constructed from a shielding element and one or more rafter elements, which allows each roof panel to be independently rotatable to a plurality of different angles. By securing the roof panels to the crossbar, and in some embodiments the uprights, in a desired configuration, one may prepare a shelter assembly that is custom designed for a particular installation location.

The invention relates to a unit for covering and uncovering a surface using adjustable slats (3), comprising: for each slat (3), a set of two carriages (10.sub.1, 10.sub.2) guided in translation along guide tracks (8); a system (II) for moving the slats (3), comprising two movement motors (12) for each carriage pair (10.sub.1, 10.sub.2) equipping a slat, each motor being mounted in a different carriage; a system (I) for orientating the slats (3), comprising at least one orientation motor (14) for each carriage pair equipping a slat, said at least one motor being mounted in at least one of the carriages; and a control device for moving at least part of the slats in translation and orientating said slats.

A morphing panel mechanism may include a central panel and a side panel, where a first edge of the side panel may be pivotally coupled to a first edge of the central panel. A morphing panel mechanism may further include a guide panel that may be coupled with a first corner of the central panel via a ball joint, where the guide panel may include a first slit. A morphing panel mechanism may further include a flexible panel, where a first edge of the flexible panel may be pivotally coupled with a second edge of the side panel, and a second edge of the flexible panel may be slidably disposed within the slit of the guide panel.
