Patent number: 8998226Abstract: A three wheeled scooter comprises a chassis having forward and aft ends with a front wheel non-pivotally mounted to the forward end and a pair of rear wheels coaxially mounted to the aft end. The chassis defines a longitudinal axis and includes a support assembly and a handle assembly extending upwardly from the support assembly. The rear wheels are configured to be angularly yawable relative to the longitudinal axis between a neutral position and a yawed position. Steering of the scooter is thereby effectuated by angular yawing of the rear wheels relative to the longitudinal axis such as by asymmetric loading of one of opposing sides of the support assembly.Type: GrantFiled: November 5, 2013Date of Patent: April 7, 2015Assignee: SBYKE USA LLCInventor: Bradley E.

Patent number: 8328209Abstract: A wiggling freewheeled vehicle comprises a folding assembly disposed between a main frame and two carrying frames. The folding assembly includes a pivot movably disposed on the main frame, clasp members integrally formed on the carrying frames, and a fastener able to fix the clasp members. Wherein, the clasp members are pivotally engaged with each other at a place where the pivot could fitly penetrate. By wrapping the main frame in the clasp members that are fixed by the fastener, the vehicle is available for a smooth operation. Oppositely, by releasing the main frame from the clasp members, the vehicle could be folded or collapsed while bending the main frame. Moreover, the collapsed vehicle allows the main frame to be arranged tightly abreast the carrying frames for achieving a compact structure. Thus, the collapsed freewheeled vehicle contributes to a reduced dimension and is beneficial for transportation and storage.Type: GrantFiled: March 10, 2011Date of Patent: December 11, 2012Inventor: Tong-Pei Tsai

Patent number: 7837209Abstract: A person rides the Tri-Axial Control Device standing on pedal assemblies. The pedal assemblies are attached to a control axial member thus forming the Tri-Axial Control Device. The control axial member on the vertical stick, can rotate fore and aft, and turns the front skis and/or wheels. Changing the angle of the vertical stick side-to-side changes the pedal angle. If the rider falls forward the front stick can rotate away. Various torsion controls rod assemblies and pedal assemblies can be utilized to create a unique tri axial device. The device can be folded, is lightweight and can be manufactured without welding. No special equipment or training is required to operate the device. In addition to its entertainment uses, the mounting device for portable electronics can also be used for added safety by adding a global positioning system or other electronic signal device, allowing safety personnel to locate the rider.Type: GrantFiled: May 10, 2007Date of Patent: November 23, 2010Inventors: Adam Micheal Spencer, Deserai Marie Spencer

Patent number: 6517092Abstract: A pushcart comprises two wheels attached to a fixed rear transverse member and two wheels attached to a pivotal front transverse member. The rear and front transverse members connect to a slanted longitudinal member. The wheels are affixed via a fork assembly to the ends of the respective members. The placement and slanting of the longitudinal member, as well as an almost upright steering column, enables an operator to achieve a lower center of gravity, for greater maneuverability and control during use. The platform comprises closely spaced bars affixed to the longitudinal member and to the fixed rear transverse member. The closely spaced bars provide lateral support to the longitudinal member as well as a platform for riding the pushcart. A cover plate shields the one or more tie rods from foreign matter and provides an alternate foot location for the operator during the performance of tricky maneuvers.Type: GrantFiled: March 5, 2002Date of Patent: February 11, 2003Inventor: Allen Dale Humphrey
