The present invention provides a double parallelogram vertical lifting device comprising a linkage mechanism and a pushing device. The linkage mechanism comprises a first shaft seat, a second shaft seat, a third shaft seat, an upper support unit movably coupled to the first shaft seat and the second shaft seat on both ends, and a lower support unit movably coupled to the second shaft seat and the third shaft seat on both ends. The upper support unit is provided with a first gear, and the lower support unit is provided with a second gear that meshes with the first gear. The pushing device has one end set on the upper support unit and the other end set on the lower support unit. The invention utilizes the interaction of the first gear and the second gear to generate a reaction force, which enables the lower support unit to cooperate with the upper support unit to move up and down synchronously, and achieves the effect of simple structure and large load capacity.

An apparatus for raising and lowering a vehicle cover is provided. The apparatus includes a flexible member having a first end and a second end, the flexible member configured to flex so that, with the first end positioned adjacent to a vehicle and the second and positioned generally higher than the vehicle, the second end raises the vehicle cover up from the vehicle and lowers the vehicle cover down towards the vehicle. The second end of the flexible member is configured to retain the vehicle cover.

An 11-device-in-one system (which can be used as 360-degree-rotatable rollable portable lockable collapsible expandable carport, green house, gazebo, storage, attic, awnings, tent, workshop, outdoor tables, booth, and RV port) comprises: round bars; square bars releaseably attached to the round bars; 360-degree rotatable lockable wheels rotatably attached to the round bars; canvas roof panels; canvas side panels; canvas end panels; canvas gap-covering panels; panel-lifting Velcros sewn to the side and gap-covering panels; panel-sealing zippers sewn to the end panels (for forming doors); panel-sealing grommets attached to the roof, side, and end panels; bungee cords and balls inserted through the grommets (for attaching the roof, side, and end panels together); first telescopic arms foldably and releaseably attached to the round bars; second telescopic arms foldably attached to the first telescopic arms; feet welded to the second telescopic arms (for attaching to each other over the roof panels to form the frames for booth signs); and toes welded to the round bars (for releaseably locking the feet thereon to form the frames for awnings and tables).

A retractable canopy having a fixed support coupled to a movable boom, an actuator to move the movable boom from a first position proximate a first end of a fixed support to a second position proximate a second end of the fixed support, at least one link coupled to the fixed support and the movable boom, at least one strut rotatably and translatably coupled to the at least one link, and a cover coupled to the fixed support and the movable boom to be deployed from a storage configuration to a deployed configuration by movement of the movable boom.

A shelter for an automobile has a pair of tracks positioned on opposing sides of the automobile and rest on a supporting surface such as the floor of a garage or car-port. A plurality of frames each having a u-shaped contour extend on opposing sides and over the automobile and are spaced apart from it. The terminal ends the frames are engaged with trucks which are in rolling engagement with the tracks. A canopy of a flexible material is attached over the frames and is movable between a folded state and an unfolded state when the trucks are moved within the tracks. The tracks have mutually orthogonal roller contact surfaces and the trucks have mutually orthogonal rollers positioned for rolling on the roller contact surfaces of said tracks. The canopy is able to be withdrawn from either of opposing sides and is further able to be drawn over the automobile to the supporting surface at both opposing sides.

A wheeled land vehicle covering system configured for one-person operation, the covering system having a covering system frame composed of a plurality of spaced apart uprights which support an overhead track from which a vehicle cover is suspended that is extendable along the track to cover a vehicle and which is retractable to uncover the vehicle. Each one of the uprights is height adjustable to adjust how far a top of the cover is above a roof of a vehicle to maintain a ventilation space therebetween. The cover is configured for one-person removal for storage when it is disposed in the fully retracted position. Such a cover also is configured for one-person installation when it is desired to reinstall the cover. The cover is attached by a hanger arrangement that enables extension and retraction of the cover by enabling relative extensible and retractable movement of the cover along the track.
