Abstract: The present invention comprises of a lever drivetrain device for control of a vehicle generally including at least one lever shaft with a repositionable scrub brake to inhibit motion of the wheel. The lever shaft is demountably coupled to a receiver via a socket secured to a gear of a gear assembly. The lever permits a multitude of hand positions to vary effort. The scrub brake is demountably coupled to the lever shaft and can be located at a multitude of positions to vary braking load and lever engagement position. In some embodiments, the scrub brake is comprised of material of high coefficient of friction and optimized geometry for braking performance and service.

Abstract: A wheel brush for a wheelchair has a brush assembly that is slidably disposed within a main housing and biased therein via a spring. A brush head is held within one end of the brush assembly so that a portion of the bristles of the assembly extend beyond an open end of the main housing. The device is attached to a brake arm of the wheelchair via a mount member that has a channel such that the brake arm is received within the channel. The wheellock assembly pushes the device toward a rear wheel of the wheelchair such that the bristles engage the wheel and brush dirt off the wheel as the wheelchair rolls being biased thereonto by the spring. The mount member acts as the brake arm for the wheelchair.

Abstract: A wirelessly controlled wheelchair assembly and method of operating thereof is described. The wheelchair assembly comprises a wheel driving unit, a seat edge and footrest lifting unit, a back-rest lifting unit and a seat retracting unit. The wheelchair assembly further comprises a microcontroller electronically coupled with the wheel driving unit, the seat edge and footrest lifting unit, the back-rest lifting unit and the seat retracting unit. The microcontroller is configured to execute a plurality of commands to wirelessly control the operating of the wheelchair. The plurality of commands comprises commands for displacing the wheelchair from a source location to a destination location, lifting the user to slightly detach from the seat, opening the seat by retracting the one or more panels of the seat to enable accessibility of a toilet, move the user in the downward direction and reversing the above steps to restore the user in normal sitting posture.

Abstract: A brake system for a wheelchair comprises a lever assembly adapted to be movably connected to a wheelchair frame, the lever assembly having a handle portion for hand manipulation. A brake unit is adapted to be pivotally connected to relative to the wheelchair frame, the brake unit having a brake end adapted to contact the wheel. An actuator portion and a follower portion are in the brake system, the follower portion cooperating with the actuator portion for the brake unit to be selectively displaceable between at least two configurations, including a floating configuration in which the brake end contacts the wheel so as to automatically pivot into blocking contact with the wheel when the wheel rotates rearwardly, while allowing a forward rotation of the wheel, and a locking configuration in which the brake end is manually locked into blocking contact with the wheel.

Abstract: A wheelchair includes 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. 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. Each rear wheel may include a push-rim having an elastomeric outer layer to facilitate manual gripping and an externally facing generally flat side face. The frame can include first and second spaced apart and unitary tubes which each extend in an unbroken manner from a wheelchair seat to a wheelchair forward region.
