    Abstract: A wheelchair comprises a frame and first and second rear wheels that are each independently mounted to the frame via a respective mounting hub. Each rear wheel is detachably mounted to its respective mounting hub at two or more distinct hub mounting points. Either or both of the hub mounting points can be movable with respect to a remainder of the hub, for example via a pivoting arrangement. A disk can be positioned at the rear wheel and a stop element located at the mounting hub can be selectively operated to interfere with the disk to prevent rotation of that rear wheel. The frame can comprise first and second spaced apart and unitary tubes which each extending in an unbroken manner from a wheelchair seat to a wheelchair forward region.

    Abstract: A foldable wheelchair includes a pair of front legs, a pair of rear legs, a seat frame, a dual-hinge joint, and a pair of armrests. A front pivoting means is pivotally connected to the seat frame and the front legs. A rear pivoting means is pivotally connected to the seat frame and the rear legs. A bottom of the dual-hinge joint is pivotally connected to a rear of the seat frame. A top of the dual-hinge joint is pivotally connected to a backrest body. Therefore, the front legs can be folded backward by the front pivoting means and the rear legs can be folded forward by the rear pivoting means. The tilt angle of the backrest body can be adjusted and the backrest body can be folded forward. Thereby the volume of the wheelchair can be reduced.

    Abstract: The present invention is directed to a bi-folding wheelchair (10) with side frames (12) and (14) that fold together with a compound scissor action moving the large rear wheels (96) to a central location while the backrest (50) is folding downwardly. Two separate locking mechanisms (28) and (40) hold the frame apart in the upright position while two additional locking mechanisms (77) hold the backrest (50) upright or down in the collapsed position. All the major components of the conventional wheelchairs like the foot rests, the arm rests, large wheels, caster wheels and the backrest fit into a compact package narrower than the unfolded wheelchair and slightly larger than the diameter of the back wheels with all parts folding in and out simultaneously. The large rear wheel assemblies can be quickly removed further reducing the size and weight of the device for shipping or storage.
