Patent number: 7637521Abstract: A bracket attaches rigidly to the steering head tube member at the front of a motorcycle frame, so that the fork steering assembly can be relocated and pivotally attached to the front of the bracket. This bracket permits the fork steering assembly to be mounted in a new position which is ahead of, and higher, or lower than its former, manufacturer's specified position. The steering axis can be positioned such that it is tilted at a greater angle of inclination from the vertical, permitting use of longer fork tubes. The bracket permits any motorcycle to be reversibly modified to have the appearance and handling characteristics of a chopper style motorcycle. No modifications to the motorcycles frame are needed, in order to relocate the fork steering assembly. Thus, the originality and value of the motorcycle, if the owner decides to, later, revert to the original appearance, is maintained.Type: GrantFiled: July 1, 2005Date of Patent: December 29, 2009Inventor: Robert William Grant

Patent number: 7614632Abstract: The present invention discloses a folding bicycle comprising a head and a frame, wherein the head includes a handlebar, a handlebar stem, a folding joint, and a front fork, and the front fork has two fork blades each of which is inwardly recessed. When the handlebar is folded downwards with the handlebar stem, the handlebar can be further folded and placed in the recess of the fork blade without interfering with the fork blade. Thus, the folding bicycle can be further folded with a less folded volume.Type: GrantFiled: January 12, 2007Date of Patent: November 10, 2009Inventor: David Tak-Wei Hon

Publication number: 20090152829Abstract: A knee scooter includes a substantially V-shaped chassis formed by a pair of extensions joined together at a vertex. At the vertex, the extensions form an angle of about sixty degrees. Further, the extensions establish a foot-space in the interior of the angle and define a chassis centerline that bisects the angle. An adjustment tube is selectively engageable with the first extension of the chassis to orient the adjustment tube substantially perpendicular to the plane of the chassis. Further, engagement with the first extension off-sets the adjustment tube from the centerline of the chassis. In use, a user rests one knee on the seat while propelling the knee scooter with his/her other leg in the foot-space.Type: ApplicationFiled: December 14, 2007Publication date: June 18, 2009Inventor: Michael Dale Anderson
