| 20100264620 | WHEELCHAIR - A system for providing an automated axial force to a continuously variable transmission (CVT) in a wheelchair. An electronic transmission control receives one or more input signals generated by throttle position or other variables. The microprocessor generates an output signal that adjusts the axial force applied to a CVT thereby automatically adjusting the input to output ratio. The invention also provides a manually controlled variator is designed for use on a wheelchair. The manual shifter hydraulically adjusts an axial force imparted on a variator in communication with a wheelchair wheel and a hand rim. Application of the axial force causes the hand rim input and wheelchair wheel output ratio to change, permitting a wheelchair operator to manually adjust the input to output ratio to more easily operate the wheelchair. | 10-21-2010 |

The tricycle includes a second rear wheel coupled to the frame. The tricycle includes a front suspension system and a rear suspension system functionally coupled to the frame. The tricycle includes a drive system coupled to the frame and a wheel hub fixedly coupled to the first drive shaft. The drive system includes a transmission system coupling a first drive train to a second drive train. The tricycle includes a locking device configured to lock the relative position of the wheel hub and the rear axle, wherein the locking device is selectably adjustably between a first mode and a second mode. The first mode includes the wheel hub and the rear axle locked together, and the second mode includes the wheel hub and the rear axle shaft independently rotatable. | 03-28-2013 |
| 20140265210 | SCOOTER HAVING A VARIABLE SPEED CAM DRIVE SYSTEM - This invention is directed to a variable speed drive system comprising: a frame having front and rear wheels; reciprocating pedals rotatably attached to the frame for supporting the rider; a pedal cam attached to one of the pedals at a hub where a distance between the hub and a first sprocket of the pedal cam is less than a distance between the hub and a second sprocket of the pedal cam; a coupling cam attached at a front axle and operably connected to the pedal cam so that when the pedal cam rotates when force is exerted downward on the pedal, the coupling cam rotates in an opposite direction from the pedal cam; and a drive sprocket carried by the coupling cam and linked to a wheel sprocket by a drive chain so that when the coupling cam rotates, the drive sprocket rotates causing the rear wheel to rotate. | 09-18-2014 |

| 20130307244 | IMPROVEMENTS MADE TO A REVERSER MECHANISM APPLIED TO THE REAR AXLE OF A WHEELCHAIR - A reverser mechanism particularly developed to provide better posture to the wheelchair user and a more efficient propulsion during a forward movement (wheelchair touch) by means of the application of a traction force to the handrims, which is contrary to the rotating movement of the rear wheels (movement contrary to the propulsion), allowing the wheelchair user to adopt a more comfortable and straight position during the effort made to move the wheelchair forward. | 11-21-2013 |

| 20080203696 | Abcycle or abdomicycle vehicle operated by upper body and steering system with leaning body - The Abdomicycle is a three or four-wheeled vehicle, (depending upon vehicle model) on which a rider sits upon a seat, leans back against a backrest which is provided for comfort and safety purposes and propels the vehicle either forward or reverse by a reciprocating motion on a bar that encloses them as they sit on the Abdomicycle. The bar is connected to either the single or dual rear wheels via a crank type mechanism that allows the linear pushing/pulling of the bar from front to back to be converted into a circular motion for the purpose of driving the rear wheel or wheels. The occupant's feet rest upon a forward steering linkage system that allows either foot pressure, or the leaning position of the occupant's body to turn the vehicle to the right or left. The vehicle includes a braking system connected by cable to the wheel(s) for the purpose of stopping the vehicle. The Abdomicycle is designed as a manually powered vehicle for exercises. However although it may defeat the purpose, motor or engine can be attached. Further more this system can apply to any vehicle such as ATV to stabilize turning. | 08-28-2008 |
| 20090020978 | Gear Shifting System Particularly Adapted to Bicyles - A gear shifting system ( | 01-22-2009 |
| 20090026727 | Automatic transmission for electric vehicle hub - An automatic transmission for an electric vehicle hub includes an external motor rotor fixedly connected with a motor shaft; a sun gear; at least three primary planet gears which are engaged with the sun gear; and at least three secondary planet gears coaxially fixed with the primary planet gears. The primary and the secondary planet gears are engaged with a primary and a secondary internal gears, and the secondary internal gear has a diameter greater than that of the primary internal gear. The rotating disk is arranged between the primary internal gear and the secondary internal gear, and a hub is fixed to exterior of the rotating disk. The automatic transmission further includes a clutch device, making the rotating disk and the primary internal gear contact with each other for a transmission of slower rpm, and when the rpm reaches critical, at a high-speed rotation. | 01-29-2009 |
| 20110115189 | Bicycle Transmission System - An enclosed bicycle drivetrain is provided that produces a range of drive ratios suitable for any riding purpose. The enclosure of substantially the entire drivetrain is made practical by the synergistic cooperation of a planetary drive system using a single chain ring and a streamlined rear derailleur system that separates the tensioning and chain guiding functions of a conventional rear derailleur, allowing the rear derailleur components to remain substantially within the shadow of the outer perimeter of the bicycle frame. The planetary drive system is provided with a unique compound pawl that may be easily disengaged from a planetary ratchet member under full riding loads by the application of a small force to destabilize the pawl. A unique shift buffer mechanism cooperates with the rear derailleur system to buffer and store up to the full range of available shift commands. | 05-19-2011 |
| 20130277940 | PROPULSION SYSTEMS FOR MANUALLY OPERATED MOBILITY DEVICES - A propulsion system for a manually-operated mobility device includes a hand rim configured to receive a propulsion force from a user of the manually-operated mobility device, a wheel hub fixedly attached to a wheel for the manually-operated mobility device, and a planetary gear system including a sun gear, a ring gear, and one or more planetary gears disposed between the sun gear and the ring gear. The one or more planetary gears are supported by a planet carrier. One of the sun gear and the ring gear is fixedly coupled to the hand rim and the other of the sun gear and the ring gear is fixedly coupled to the wheel hub. | 10-24-2013 |

The vehicle frame has two wheels and an input tubular member. A crank is attached at each end of the input tubular member. The multi-ratio transmission system includes: a multi-ratio transmission device, a first sprocket, a second sprocket and a chain. The multi-ratio transmission device is installed inside the input tubular member and located at a rotation center of the cranks. The second sprocket is coaxially installed on a wheel axle of a driving wheel. The chain is engaged with the first sprocket and the second sprocket. When the cranks rotate, the rotation motion of the cranks are transmitted to the first sprocket through the multi-ratio transmission device, subsequently, the motion is transmitted to the second sprocket from the first sprocket through the chain, thereby propelling the driving wheel to rotate. | 04-16-2015 |
