An auxiliary drive device for a wheelchair has at least one freely pivotable electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The coupling mechanism includes a movable locking element which is movably supported in the coupling mechanism. The movable locking element can be in a locking position in which it causes locking in a positive-locking manner so that the auxiliary drive device is coupled to the wheelchair and, by operation of a handle, the locking element can be moved in a release position in which uncoupling of the auxiliary drive device from the wheelchair is possible.

A personal transporter includes a seat, a frame having a base and a strut supporting the seat, hinged to the base and pivotable between an open configuration and a folded configuration, a pair of driving wheels and at least one non-driving wheel associated to the base defining, in use, three unaligned points on the ground, a pair of electric motors, a pair of control pedals, each associated to a respective electric motor to drive a respective driving wheel, and a support rod for supporting the strut in the open configuration, hinged to the strut and slidably mounted on the base in a guide. The base has a rear portion for supporting the at least one non-driving wheel and a pair of front portions, each hinged to the strut and integrally rotatable with a respective control pedal.

Drifting karts in accordance with embodiments of the invention are described that include a front wheel drive train and rear caster wheels that can be dynamically engaged to induce and control drift during a turn. One embodiment of the invention includes a chassis to which a steering column is mounted, where the steering column includes at least one front steerable wheel configured to be driven by an electric motor, a battery housing mounted to the chassis, where the battery housing contains a controller and at least one battery, wiring configured to provide power from the at least one battery to the electric motor, two caster wheels mounted to the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis, and a hand lever configured to dynamically engage the caster wheels to induce and control drift during a turn.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame.

A mobility device that includes support assemblies that may be secured to feet, legs, thighs, and torso of a user. An exemplary mobility device may further include an actuator that may be coupled with the exemplary support assemblies and may actuate rotational movements of the exemplary support assemblies with respect to each other. Such movement of support assemblies may accordingly move respective limbs of a disabled user. An exemplary mobility device may allow for a user to change position from a lying position to a standing position or from a standing position to a sitting position, which may significantly increase mobility of a disabled user. An exemplary mobility device may further include an exemplary wheeled base that may allow a disabled user to further move around.

A reclining wheelchair apparatus for providing a convenient way for wheelchair users to rest or be cared for includes a chair base frame and a plurality of wheels coupled to the chair base frame. A seat bottom is coupled to a base top side and a pair of pivot brackets is pivotably coupled to a base top side adjacent the base back side. A chair back is coupled to the pair of pivot brackets and moves between an upright position and a reclined position. The pair of pivot brackets rests on a pair of bracket supports when the chair back is in the reclined position. A pair of locking pins is coupled to the pair of pivot brackets and selectively engages with the base top side to secure the chair back in the upright position.

A bar handle device includes a fixing portion attached to a steering mechanism, a short portion to which grips are attached, and a long portion connecting the short portion and the fixing portion. The long portion is composed of a first bar member and a second bar member interconnected in serial, and includes a cross-linking member connecting the first bar member and the second bar member.

A convertible wheelchair system, between a wheelchair configuration and an all-terrain configuration, is provided. Embodiments include a central frame aligned along a central longitudinal axis, the central frame having a front and back bar parallel to each other and orthogonal to the central longitudinal axis, paired side bars aligned with the central longitudinal axis, and paired wheel cages, aligned with the central longitudinal axis and attached to the front and back bars, each wheel cage supporting an axle and a wheel mounted thereon. The system further includes a forward beam alignable with the central longitudinal axis, configured to support a forward wheel, and reversibly attached to the front bar. The convertible wheelchair is in the all-terrain configuration when the forward beam is attached to the frame, and the wheelchair configuration when the forward beam is detached from the frame, the central frame thereby standing without the forward beam.

A system controls assistive technologies with an assistive tool for users with movement and/or communication disorders. The system includes an electronic communication interface, a biometric sensor, a calibration module and a processing unit. The interface presents users with stimuli associated with commands and/or information that the user might select. The sensor detects the user's biometric activity and generates a biometric electrical signal. During initial calibration, the calibration module records signal characteristics associated with a biometric electrical signal detected with voluntary biometric activity. The processing unit recognizes, based on the biometric electrical signal and the signal characteristics, the user's voluntary biometric activity and commands and/or information the user wants to select. The processing unit provides control signals to the interface and the assistive tool, based on the user's selection preferences. The interface presents stimuli based on the presentation control signal, if present, or presents a scan of stimuli.
