Provided is an awning system comprising: a) two vertical tracks; b) two arms, with each arm attached at a first end to one of the vertical tracks, the arm configured to move in a vertical direction and pivot in relation to the track, each arm further configured to be extendible; c) a cross-bar, with each end of the cross-bar attached to a second end of one of the arms; d) a piece of fabric attached at one end to the cross-bar; and e) a holder placed on top of the tracks for holding a second end of the fabric; wherein the awning fabric is configured to be adjusted in both the vertical and the horizontal direction; wherein a user can move the arms vertically and extend the arms to adjust a position of the fabric. Provided is a retractable canopy system comprising: a) a track; b) a frame movably attached to the track; c) a support attached to the frame; d) a connector movably attached to the support, e) two or more rods attached to the connector; f) a canopy piece attached to the rods; wherein the awning is configured to have a stowed and deployed position that are obtained by moving the frame against the track.

A semi-permanent relocatable structure system can be used to construct structures of various sizes and configurations from various components. The components can include leg beams, eave beams, straight roof beams, and apex beams. The width of the structure can be adjusted by interchanging the straight roof beams. The structure can further be customized and adapted over time with various units so as to meet changing needs of the user.

A vertical escape structure comprises an escape housing disposed in a vertical orientation and mounted to a ground to maintain structural integrity in the vertical orientation against external flooding. The escape housing includes an interior which is sealed against water entry from exterior flooding and at least one of a staircase, a ladder, an elevator, or a lift disposed in the interior of the escape housing. The vertical escape structure further comprises a connecting walkway to connect the escape housing to a building. The escape housing has a smaller horizontal footprint than the building. The walkway is severable from the building by force without damaging the escape housing to cause water entry from the exterior flooding.

A retractable roof structure includes first and second roof support structures separated by a span distance, with first and second roof sections supported on the first and second roof support structures. A load transfer structure is configured to transfer load from a frame of the second roof section downwardly through a frame and truss structure of the first roof section to the first and second roof support structures.

A louvered pergola includes (a) a plurality of posts; (b) an elevated frame supported by the posts and defining a central frame opening; and (c) a plurality of louvers supported by the frame and extending parallel with each other across the frame opening. The plurality of louvers includes a first louver fixed to the frame, a second louver fixed to the frame opposite the first louver, and a plurality of pivotable louvers pivotably supported by the frame between the first and second louvers. The pivotable louvers are pivotable between a closed position in which the plurality of louvers partially overlap with each other to close the frame opening and an open position in which a gap is provided between adjacent louvers of the plurality of louvers.

A retractable roof for a building having a supporting frame and a high structure extending vertically above the supporting frame. The roof has at least one structure section with first and second panels. The first panel is hingeably mounted on the supporting frame at a proximal hinge and the second panel is hingeably mounted on the first panel at a distal hinge. A distal end of the second panel is suspended to the high structure with a distal cable connected to a distal motorized winch. A tackle member connects to both first and second panels adjacent the proximal hinge and the distal end, respectively, and includes a tackle wire that forms a wire side of a triangular cross-sectional shape with the first and second panels. The tackle wire connects to a winch mechanism to control a length of the wire side.

Heating louvre (11) for a louvred roof comprising at least two girders which extend parallel to each other and to which several louvres are rotatably connected between an open position and a closed position. The heating louvre (11) is provided with an underside (13). A slot is provided in the underside (13) for fitting a heating element (12) inside the heating louvre (11). After the heating element (11) has been fitted, the cavity (15) is at least partially sealed by it and the heating element (11) is provided to heat a position between the louvred roof and the ground surface by means of radiant heat. By using a slot in combination with a heating element (12) based on radiant heat, it is possible to heat the position between the louvred roof and the ground surface, as the heating element (12) is not fully surrounded by the heating louvre (11).
