ABSTRACT:
An all terrain wheelchair for outdoor recreational use is made of non-corrosive materials, such as polyethylene plastic, stainless steel and aluminum, and includes opposite frame members, a collapsible hinged brace assembly fitted between the frame members which locks in an expanded box configuration to hold the opposite frame members apart, defining an operable position for use of the wheelchair. The front and rear wheels include wide rims having horizontal ribs to provide increased traction and surface contact area when traversing soft terrain. Removable armrests are provided to aid ingress and egress of a person in and out of the wheelchair. A shade cover mounts to the frame members to provide protection from the sun and rain. In the expanded, locked position, the box shaped brace assembly provides a storage area under the seat and includes hinged doors at the rear and an open front to provide access to an interior of the box structure. The box structure of the brace assembly further accommodates a removable flotation device, and spokes on the rear wheels form paddle like structures that provide propulsion means in water.
