Thus, the arcuate convex configuration of the first face of the handlebar body satisfies the ergonomic design, so that when the user's hand holds the handlebar body, the first face of the handlebar body provides a comfortable sensation to the user's hand, thereby facilitating the user's hand holding the handlebar body.Type: ApplicationFiled: May 19, 2003Publication date: November 25, 2004Inventors: Cheng-Hsun Chiang, David Michael Anthony

Patent number: 6817265Abstract: A steering damper device attenuating the oscillations of the handlebar of a motorcycle during operation, and more particularly, a device capable of varying a damping force variable. The steering damping device prevents the adverse effect of oscillations of the handlebar that would otherwise occur when the load on the front wheel of the motorcycle becomes light. The device includes a rotary steering damper provided in a coaxial manner on a steering shaft. Either a damping force or zero damping force is produced by a variable valve arranged in the bypass passage communicating with a right liquid chamber and a left liquid chamber. The variable valve is controlled by a control device and generates a damping force in the steering damper only when the acceleration of the motorcycle as detected by the acceleration sensor exceeds a threshold value.Type: GrantFiled: March 22, 2002Date of Patent: November 16, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yosuke Hasegawa, Takeyasu Itabashi, Kanji Hayashi, Takeshi Wakabayashi, Osamu Bunya

Publication number: 20040187626Abstract: A bicycle stem and front loading handlebar clamp having a pair of C-shaped cradles provided with handlebar contacting surfaces which have an edge to edge maximum extent in the direction of the handlebar greater than the inside diameter of the cradles and wherein the cradles are characterized by the absence of straight lines and sharp corners.. Handlebar clamping stress concentrations are reduced by the configuration of the contact surfaces and further by a configuration of a moveable one of the cradles somewhat in the form of a laterally elongated cross with smooth curves at the ends and at the corners of the cross.Type: ApplicationFiled: March 25, 2003Publication date: September 30, 2004Inventor: Michael McColligan

Patent number: 6796571Abstract: A hydraulic steering damper (9) is designed to be fitted inside a steering sleeve (3) between the steering sleeve (3) itself and a steering pin (2) that is coaxial with the sleeve (3) and having an axis of rotation (A). The damper (9) includes a cylindrical lining (11), that can be fixed to the steering sleeve (3), and a cylindrical wall (13), that can be fixed to the steering pin (2). The lining (11) and the wall (13) form between them a gap (16) designed to hold a hydraulic fluid (17) and divided into a first and a second chamber (28, 29), which are in fluid communication with each other through a conduit (30). The damper (9) further includes a blade (25) attached to the cylindrical wall (13) and designed to push the fluid (17) from one to the other of the chambers (28, 29) when the steering pin (2) is rotated relative to the steering sleeve (3).Type: GrantFiled: August 21, 2002Date of Patent: September 28, 2004Assignee: Ducati Motor Holding S.p.A.Inventor: Gianluigi Mengoli

Patent number: 6764246Abstract: A bicycle handlebar stem assembly includes a stem with two lugs extending from one of two ends of the stem. A first connection member has an aperture through which the stem extends, and two recesses are defined in an inside of the first connection member so as to receive the two lugs therein. A second connection member has a clamp part on one end thereof and an insertion extends from the other end of the second connection member. The insertion is inserted in the other end of the stem.Type: GrantFiled: March 20, 2003Date of Patent: July 20, 2004Inventor: Cheng-Hsun Chiang

Patent number: 6748821Abstract: An extension for the handle bars of a motorcycle includes an insert with a projection that fits within the handle bars. The handle bars and insert are keyed so as to prevent rotational movement thereof relative to each other. A parallel bar that is clamped to the handle bars retains all of the parts in place.Type: GrantFiled: February 28, 2002Date of Patent: June 15, 2004Inventor: John C. Smith

Publication number: 20040089095Abstract: A bicycle handlebar assembly includes two brake levers connected thereto and each brake lever has two brake cables extending therefrom. The handlebar includes a bar connected to the handlebar stem and has two recesses defined in an outer surface thereof. Each recess includes two entrances which extend at angle relative to an axial direction of the recess. Each of the entrances is a plain surface. The recesses and the entrances receive the brake cables so that the brake cables do not protrude from the outer periphery of the bar.Type: ApplicationFiled: November 12, 2002Publication date: May 13, 2004Inventor: Cheng-Hsun Chiang
