The present disclosure relates to a building structure having a convertible roof with at least one moveable roof section. The moveable roof section can include an integrated overhang. The moveable roof section can also include a roller that rides on a track formed by an angle member. The convertible roof can further have a configuration that reduces rafter visibility.

A release mechanism for a transport carriage used to move an elongated beam or truss is constructed using a non-linear bearing mounted on the carriage and connected to the truss and including upper and lower bearing mounting surfaces having complementary arcuate surfaces and a layer of layers of lower friction bearing material between them. The upper and lower bearing mounting surfaces being arranged to allow one plate to move relative to the other in an arcuate path in the direction of the space of the beam or truss.

A mobile house construction (1) is easy to move with strong mobility; (2) has a high folding ratio, providing a good living experience; (3) has a simple structure and is easy to drive; (4) permits for the entire device to be factory manufactured; and (5) provides a standardization of structure, thus reducing costs. The home construction includes a main body structure and a folding mechanism. The main body mechanism is the main load-bearing structure of the mobile house, which is connected to the folding mechanism. The main structure includes a floor, a water tank, an engine, a bathroom, a kitchen, a door, a window, a load-bearing column, a load-bearing beam, and the like, and can further include several pieces of furniture. The folding mechanism can expand the internal space of the mobile house, including the left side folding mechanism, the right-side folding mechanism and the top folding mechanism.

A roof structure that can provide a drone port where a drone can stably take off and land on a sloping roof includes a sloping roof covering the upper part of a building, a drone accommodation portion that has a size capable of accommodating a drone and is provided to cut out a part of the sloping roof so that a bottom surface is substantially horizontal, a drone port that is provided on the bottom surface of the drone accommodation portion where the drone can take off and land, a cover that covers an opening formed on the sloping roof for the drone accommodation portion, and a doorway that is provided on the drone accommodation portion and allows the drone to enter and exit, in which the cover is configured to be openable and closable, and the doorway is opened and closed by opening and closing of the cover.

A cover assembly may include a housing and an elongated cover. The housing defines a chamber therein. The chamber is disposable in the ground adjacent to a side of the sand area of the jump pit. The elongated cover has a first end, a second end, and spaced-apart sides extending from the first end to the second end. The elongated cover is storable in a compacted configuration in the chamber of the housing below the surface of the ground, and the elongated cover is removable from the chamber and extendable in an uncompacted configuration over the sand area of the jump pit to conceal the sand area.

A Folded Dome like Retractable Opening Structure and Method of the present invention is an hourglass in external appearance with a narrow waist and a mirrored double truncated flexible cone-like structure, with one primary truncated flexible cone-like structure on bottom intermediately supported and connected by one secondary truncated flexible cone-like structure on top. The retractable opening of the present invention is the truncated open end of the primary truncated flexible cone-like structure, where it is flexible to expand to open toward and contract to close away from its peripheral. In operation, the double truncated flexible cone-like structure is a slider crank mechanism, where, power is applied to the secondary truncated flexible cone-like structure, the slider, which moves vertically; the primary truncated flexible cone-like structure, the crank, is rotated; and rotation of the primary truncated flexible cone-like structure forces its truncated open end, same as the retractable opening of the present invention, to uniformly move inward to close and outward to open. A Folded Dome like Retractable Opening Structure is especially suitable for expansive retractable roofs on domed structures often found on a sports stadium.

The present invention provides a sidewall system and a collapsible building using the system thereof. The sidewall system has a fixed wall, a sidewall, and a single-side eave system that has an eave panel that can be unfolded and folded along with the movement of the sidewall automatically. A collapsible building with two sidewall systems and a sliding, retractable roof is also provided. The collapsible building can create an enclosed space easily and quickly. To solve the above problems, the present invention is proposed. A retractable roof with a foldable ceiling is provided. The roof can be used on some expandable structures such as recreational vehicles or mobile houses. Compared to the traditional sliding roof, this invention combines a foldable ceiling inside the roof. The ceiling can split the roof and room which offer a better thermal insulation function.

The present invention provides a sidewall system and a collapsible building using the system thereof. The sidewall system has a fixed wall, a sidewall, and a single-side eave system that has an eave panel that can be unfolded and folded along with the movement of the sidewall automatically. A collapsible building with two sidewall systems and a sliding, retractable roof is also provided. The collapsible building can create an enclosed space easily and quickly. To solve the above problems, the present invention is proposed. A multi-layered folding roof fitted with a liftable ceiling is also provided. The roof can be unfolded and retracted in the horizontal direction, and the internal multi-piece ceiling structure will unfold and fall simultaneously with the roof due to the action of the internal slide rail. The invention can be used in a variety of buildings and mobile homes.

A collapsible modular building is constructed from at least two building modules that are joined together to form the building. Each building module is constructed to be configured in either a collapsed or erect position. In the collapsed position, each module is individually transported to a site by trailer. Once offloaded, the modules are joined together to form the building, this joining together of the modules can be done while the modules are in the collapsed position or in the erect position.

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.
