The invention discloses an unidirectionally swinging linkage shutter, a roof with the shutter and a louver blade. The shutter includes a frame and a louver blade, the frame includes a longitudinal keel, the longitudinal keel includes longitudinal keel body and a positioning bar, a pin hole is defined on the positioning bar and beyond the wall, one end of the louver blade close to the indoor is hinged on the pin hole via a pin shaft, the louver blade includes a protruding section protruding outward, a linkage connection position is defined on the protruding section. The roof with the shutter includes a transverse roof beam, a longitudinal roof beam and a louver blade, the longitudinal keel includes a longitudinal keel body and a positioning bar, the positioning bar is provided with a pin hole. The structure of the louver blade is the same as above. In the present invention, the linkage bar will not interfere after the louver blades are closed, and the sealing performance is good, and the water and wind shielding effects of the louver blades are good; it is convenient to install and disassemble the louver blades on site, and can avoid the arbitrary removal of the louver blades from the outside.

A frame truss made of two walls and a roof structure. Each of the two walls have an outer and inner chord. The outer and inner chords of each respective wall are not parallel, but the inner chords of the two walls are parallel to each other. The arrangement of the inner and outer chords of each wall creates an exterior overhang with respect to the ground. Each of the walls converge at their bases and are attached at their bases to a plate. The roof structure attaches to the top of each of the walls and spans between them creating a frame that can be assembled in conjunction with similar frames to construct a building system.

The present invention relates to a portable building assembly providing a complete structure configured for onsite construction. The structure once packed down can be delivered to site in a flat packed form most efficient for transportation.

A system including a plurality of servers mounted in server racks and a cold aisle containment (CAC), the CAC including a roof system, wherein the roof system includes a frame, a plurality of roof panels, wherein each roof panel is connected to the frame and is rotatable with respect to the frame, and a holding mechanism for holding a first roof panel among the plurality of roof panels in a closed position, wherein each roof panel among the plurality of roof panels overlaps at least one adjacent roof panel among the plurality of roof panels, and wherein release of the holding mechanism causes each of the roof panels to rotate to an open position in a cascading manner.

A solar tracking carport comprises a supporting structure including a foundation and at least two columns connected or connectable to the foundation; a three-dimensionally rigid canopy deck having a length from a first edge to a second edge of at least one car, the three-dimensionally rigid canopy deck including one or more upper blocks, each of the upper blocks being rigid at least in its longitudinal direction, each of the upper blocks including at least one solar panel; a deck frame configured to support the one or more upper blocks, the deck frame including a torque transmitting member; a rotation enabling connection configured to rotatably connect at least the torque transmitting member of the three-dimensionally rigid canopy deck to the at least two columns of the supporting structure; and a drive system configured to control tilting of the three-dimensionally rigid canopy deck about the supporting structure over one axis of rotation to a first maximum angle in a first direction and to a second maximum angle in a second direction, the first maximum angle preventing the first edge of the three-dimensionally rigid canopy deck from going below a first minimum threshold height, the second maximum angle preventing the second edge of the three-dimensionally rigid canopy deck from going below a second minimum threshold height.

This disclosure relates to a louvered patio cover. The louvered patio cover may comprise a frame with support beams, louvered panels, support beam couplers, an actuator, a gutter, and/or other components. The support beams may have angled ends. The louvered panels may be rotatably coupled to the support beams. A support beam coupler may comprise first and second receivers. The first receiver may be configured to receive an angled end of a first support beam, and the second receiver may be configured to receive an angled end of a second support beam. The angled ends of the first and second support beams may face, meet, and/or abut each other when received by the first and second receivers. The actuator may be configured to rotate the louvered panels. A gutter may comprise a lighting channel configured to hold a light source for lighting an area under the louvered patio cover.

The invention relates to an installation including: a series of orientable slats (3); a slat orientation system (3) adapted to ensure the pivoting of the slats in order to occupy a closed position or an open position; a system for moving in translation the slats (3) between a stowed position and a deployed position; and a control device piloting the displacement system and the orientation system, on the one hand to define from the stowed position of the slats a transition area (Ev) in which each of the slats exiting its stowed position switches from its open upright position to its closed position and conversely for each of the slats arriving to its stowed position, and on the other hand to ensure the translational displacement of the slats in the closed position outside the transition area (Ev).

A roof system including a frame, a plurality of roof panels, wherein each roof panel is connected to the frame and is rotatable with respect to the frame, and a holding mechanism for holding a first roof panel among the plurality of roof panels in a closed position, wherein each roof panel among the plurality of roof panels overlaps at least one adjacent roof panel among the plurality of roof panels, and wherein release of the holding mechanism causes each of the roof panels to rotate toward an open position in a sequential manner.

A new louver, and a louvered roof assembly having a plurality of these louvers is provided wherein the plurality of louvers. are movable within a frame between an open condition and a closed condition. The louvers, each having first and second ends, are pivotally coupled to the frame for rotation about an axis. A linear drive motor is coupled to a moveable arm bar to which each louver is connected by a pin which pin is attached at the pin's opposite end to a member disposed within the center of each respective louver. Single set and dual sets of louvers may be operated by a single linear drive actuator.

A sun shade includes a cover that is extendable and retractable, a guide rail assembly that is engageable with the cover and defines a first path of movement via a first movable engagement point between the cover and the guide rail assembly, and a support bracket that is engageable with the guide rail assembly and arranged at a lower position relative to the cover. The support bracket defines a second path of movement for the guide rail assembly with the cover via a second movable engagement point between the guide rail assembly and the support bracket.
