A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

A parking apparatus has a parking platform mounted to stanchions for movement between lower and upper positions. Left and right lever assemblies have inner surfaces facing toward one another and outer surfaces facing away from one another. Each lever assembly includes a first lever with an upper end articulated to the parking platform and a lower end articulated to a base. A piston-cylinder assembly moves the lever assemblies to raise or lower the parking platform. The upper end of each lever assembly has an inner bearing rotatably mounted adjacent the inner surface of the respective lever assembly and an outer bearing mounted adjacent a surface of the parking platform facing away from the inner bearing. A pin engages the inner and outer bearings, passes through the upper end of the respective first lever and through a part of the parking platform facing the outer surface of the respective lever assembly.

The disclosure relates to an automated parking device comprising a frame, on which at least one movable, in particular raisable or lowerable platform is provided, and the automated parking device is equipped with a chain, part of which forms at least part of a chain deflection system. The chain deflection system consists of at least one chain piece, preferably a roller chain piece, and a deflection piece.

A parking apparatus has left and right vertical stanchions and a parking platform between the stanchions for supporting a parked vehicle. Carriages are mounted to opposite sides of the parking platform and have wheels that engage in channels formed in the stanchions so that the parking platform can be raised and lowered. The channels are configured to widen or tilt toward the bottom ends of the stanchions. These shapes of the channels near the bottom ends of the stanchions are configured relative to the carriages so that the parking platform tilts slightly forward when the parking platform is near the lowest position so that a vehicle can be driven on and off the parking platform. However, the engagement of the carriages and the stanchions cause the parking platform to tilt slightly rearward as the parking platform moves up to prevent the vehicle from rolling off the parking platform.

The present application provides methods for loading and unloading high capacity storage equipment to a solar power canopy. The methods and structures may include horizontal support members have mechanisms to engage corresponding mechanisms on a compartment housing the high capacity storage equipment. The mechanisms may include plates, flanged surfaces, rails, tracks, hook assemblies, and ridges. The methods and structures may include a superstructure that is coupled to an moves with respect to the solar power canopy frame. The superstructure may pivot and/or rotate to allow loading and unloading. The methods and structures also may include cabinets or cubicles sized to receive one or more compartments housing the high capacity storage equipment.

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.
