    Abstract: A folding wheelchair is easily convertible between a folding wheelchair of a first type and a folding wheelchair of a second type through the use of conversion components, some of which are mounted permanently to the wheelchair and some of which are received by the mounted conversion components. In one form, the first type is a folding beach wheelchair while the second type is a folding all-terrain or trail wheelchair. Conversion is achieved through changeable front and back wheels. For instance, the folding beach wheelchair includes right and left rear wheels having oversized, low pressure tires. Right and left front brackets are mounted to the existing frame and are configured to receive right and left wheel assemblies, having smaller, low pressure tires mounted for pivoting movement. The folding all-terrain wheels have solid, high pressure or the like tires.

  • Patent number: 8851213
    Abstract: A motorized wheel chair is equipped with a safety system for bringing the wheel chair to a stop if a wheel chair user should experience an emergency situation which renders the user unable to safely control the wheel chair while in use. The safety system utilizes at least one switch mounted to an upright backrest for sensing whether or not the user's back is in contact with the backrest. If the user's back is in contact with the backrest, the wheel chair is operative and may be controlled in a normal manner. If the user's back moves out of contact with the backrest, whether voluntarily or because of an emergency situation, the safety system operates to disable operation of motors which operably propel drive wheels of the wheel chair, thus causing the wheel chair to be inoperative and bringing the wheel chair to a stop if in motion.

  • Patent number: 8684113
    Abstract: A device for adapting a manual wheelchair to drive with a powered wheel is disclosed. The device attached to the wheelchair provides means for raising the wheelchair front caster wheels and simultaneously having the powered wheel contact the driving surface. The disclosed device may be rotated so that the powered wheel lifts from the surface as the front caster wheels are lowered to contact the driving surface enabling manual operation of the wheelchair. The disclosed device includes a mechanism for steering the powered wheel, controls for varying the forward or backward speeds and braking. The device may be detached from the chair and is adaptable to fit a large variety of wheelchairs with capability for ergonomically adjusting the steering column for the comfort of the user. Optional human interface devices may be incorporated so the chair occupant may control speed and steering by operating a joystick, head array or other such devices.

    Abstract: A detachable and foldable wheelchair frame rigidizing device. A pair of opposing top surfaces each includes one of a pair of opposing bottom surfaces and a cut-out pattern forming finger elements extending beyond each opposing bottom surface. The finger elements are arranged in an alternating interlocking fashion such that when the opposing top surfaces are folded together to form a planar surface the finger elements fit closely together and the opposing bottom surfaces are sized to extend beyond each of their respective top surfaces to support at least a portion of each of the finger elements from the opposing top surface when in an unfolded position. Frame attachments are attached to the perimeter of the opposing bottom surfaces. A hinge is centrally positioned to join the finger elements from each opposing top surface.

  • Patent number: 8651507
    Abstract: A mounting assembly for attaching auxiliary equipment to a wheelchair includes multiple adjustment features. In the preferred embodiment, different wheelchair widths may be accommodated by utilizing attachment arms that pivot co-axially with a main column of the auxiliary equipment. The mounting assembly preferably includes a pair of arms and a pair of links that extend from the arms. The lengths of the links and the arms may be adjusted by rotation of a rod portion of each arm and each link, but other means for enabling changes in length are possible. The links are preferably pivotally connected to the arms, so that the distance between the ends can be varied on the basis of the particular wheelchair. Ball-and-socket joints are used, but rotatability of the sockets permits flexibility of the orientations of the joints. Additionally, a vernier adjustment effect may be included to permit adjustments in the angle of the main column.

  • Publication number: 20140042727
    Abstract: The present invention relates to a reconfigurable wheel chair designed to assist physically challenged people to use toilets without moving off wheel chairs. The wheel chair comprises a split seat, which includes a central retractable part. The rest of said seat is a sliding part, which rests on rails and is free to move over the toilet seat when enabled using mechanisms known in the art such as motor screw mechanism, etc. The wheel chair further comprises a sensor for aligning the chair to the toilet seat automatically. In use, once the wheel chair is aligned, the retractable part of the seat moves down. The roller at the back of the wheelchair seat is moved down onto the toilet to provide additional support. The motor is then activated that moves the sliding part of the seat over the toilet seat.
