| 20100283216 | BICYCLE WITH TWO FRONT WHEELS - A bicycle with two front wheels includes: a main frame provided at its front end with a vertically oriented head tube; a pair of front wheels non-rotatably provided on both ends of a front wheel shaft held below the head tube; a rear wheel that is rotatably supported by a rear end of the main frame; driving means for driving the front wheels; and steering means for steering the front wheels. The steering means includes a steering handle, and a steering shaft extending from the steering handle downward and including a vertical steering shaft portion that is rotatably supported by the head tube and that has a lower end for turning the front wheel shaft. The driving means includes a horizontal driving shaft pivotally supported by the main frame, and a vertical driving body that can be rotated by the horizontal driving shaft and that is coaxial with the head tube, and the vertical driving body rotates the front wheel shaft through driving-interconnection means. | 11-11-2010 |
| 20110278814 | PERSONAL TRANSPORTATION DEVICE - A personal transportation device comprises a riding platform supported by one or more wheels, a steering mechanism at least partially embedded in the riding platform and a drive wheel assembly. A first wheel may be steerable while a second wheel is a slave wheel. The steering mechanism may be foot-operated. The drive wheel may be hand-propelled and non-steerable. The drive wheel is operatively connected to a drive sprocket and chain and is coupled to the riding platform by a platform frame. The personal transportation device may comprise one or more track arm assemblies coupled to the drive wheel assembly such that movement of the track arm assemblies operates the drive wheel assembly and rotates a drive wheel to propel the vehicle. | 11-17-2011 |
| 20120001400 | TRICYCLE WITH FRONT AND REAR STEERING - A vehicle with front and rear steering is disclosed. The vehicle can be a cycle. The cycle includes a front wheel steered by a front hand-steering mechanism, and two back wheels steered by a back hand-steering mechanism. The back wheels are dual inclined casters with full rotational movement. A drive train forward of the front wheel drives the front wheel, while a rider is inclined in a seat in a recumbent orientation. The front and rear steering provides unlimited maneuverability and turning capabilities. | 01-05-2012 |
| 20120181770 | CYCLE HAVING AN ARM DRIVE AND A LEG DRIVE - The invention relates to a two-wheeled cycle having an arm crank drive and a leg crank drive. The cycle has steering by means of shaft legs, wherein the cycle is steered by tilting, and the cycle has at least one steering support element which dampens, limits, or fixes the steering motion or exerts a restoring force in the straight-ahead position of the steering wheel. In addition, the geometry of the steering axis and of the fork offset are optimized. | 07-19-2012 |
| 20140091550 | DUAL STEERABLE VEHICLE - A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another. | 04-03-2014 |
| 20160144927 | Scooter Generating Power By Rowing In Both Directions - Disclosed herein is a scooter-type vehicle comprising at least one front wheel and at least two rear wheels, wherein power for forward motion is developed by the occupant of the vehicle pushing and pulling a propulsion lever, which also serves as the steering mechanism for the vehicle, in both directions. A novel inventive gearbox mechanism is contained in a small housing, which allows for the drive wheel, through the steering means, to be rotated fully 180 degrees, allowing backward motion of the vehicle as well. | 05-26-2016 |
| 20160167728 | BICYCLE HAVING FRONT WHEEL DRIVING MEANS | 06-16-2016 |
| 20160185416 | Bicycle with Coordinated Pedal and Upper Body Leverage - A cycle or bicycle is driven both by rotation of pedals that drive a rear wheel in a conventional manner, and by fore and aft movement of the handlebars. Fore and aft movement of the handlebars about an adjustable hinge, which also rotate as a unit about a front wheel turning axis, is transmitted to a drive rod. The drive rod then drives an actuator mechanism which transfers force due to movement of the handlebars to the primary drive mechanism through which pedal power is also applied to the rear wheel. Forces generated by this movement of the handlebars is additive to forces applied by the rider directly to the pedals, in a coordinated manner that does not inhibit steering of the bicycle. | 06-30-2016 |
