Thus, during the compression of the shock-absorber system, the top pivoting link oscillates in relation to the chassis, and about an axis that is perpendicular to the chain line.Type: GrantFiled: January 31, 2008Date of Patent: January 8, 2013Assignee: DecathlonInventors: Cyril Beaulieu, Zigor Garate

Publication number: 20120326416Abstract: A bicycle can include a suspension system with a shock absorber. The shock absorber can have a sag position which can be adjustable. Sag refers to the amount of movement experienced by the suspension under a static load, such as that of the weight of a rider. Methods and systems to set sag can include at least one valve in fluid communication with a gas chamber of the shock absorber. In some embodiments, the at least one valve can be used to automatically set the sag position based on an individual's weight and riding position.Type: ApplicationFiled: September 7, 2012Publication date: December 27, 2012Applicant: SPECIALIZED BICYCLE COMPONENTS, INC.Inventor: Jan Talavasek

Publication number: 20120280470Abstract: A bicycle frame assembly having a number of rotatable members configured to absorb shocks and impacts associated with operation of the bicycle. The assembly includes a frame constructed to support a rider and a chain stay having a rearward end that extends toward a wheel hub and a forward end that is pivotably connected to the frame. An absorber is pivotably connected to the forward end of the chain stay and extends to a rocker arm that is pivotably connected to the frame. A seat stay is pivotably connected to a rearward end of the rocker arm and extends to the rearward end of the chain stay. The rearward ends of the seat stay and the chain stay are pivotably connected to rotate about a common axis.Type: ApplicationFiled: July 17, 2012Publication date: November 8, 2012Inventors: James Colegrove, Dylan Howes, Jose Gonzalez

Publication number: 20120228850Abstract: A rear suspension system for a bicycle which includes a front part having a top tube, a down tube and a seat bracket, and a rear part has seat stays and chain stays. The seat tube has a frame located close to the bottom bracket. A top link unit is pivotably connected to the seat stays and extends toward the front part to form a first pivotal portion. The chain stays are connected to a down link unit which extends into the frame. A second pivotal portion is formed at the mediate portion of the down link unit. A shock-absorbing device has its top end pivotably connected to the first pivotal portion and the lower end of the shock-absorbing device extends into the frame and is pivotably connected to the second pivotal portion which is located close to the axis of the seat tube to provide stable buffering action.Type: ApplicationFiled: March 10, 2011Publication date: September 13, 2012Applicant: KINESIS INDUSTRY CO., LTD.Inventor: JIMMY TSENG

Patent number: 8262115Abstract: A variable height seat bicycle suspension seat post assembly for bicycles that descends at an angle toward the rear of the bicycle while providing a suspension component to the seat post. The downward angle at which the seat post assembly travels lowers the rider's center of gravity and improves the balance, stability, handling characteristics, and traction of the bicycle while at the same time absorbing shocks and other impacts caused by rough terrain.Type: GrantFiled: November 17, 2009Date of Patent: September 11, 2012Inventor: Joshua D. Mackenroth

Patent number: 8196946Abstract: A suspension structure includes a pair of right and left cushion units. The right cushion unit is constituted of a compression coil spring and a right damper, and the left cushion unit is constituted of only a left damper having an outer diameter smaller than a diameter of the compression coil spring and larger than a diameter of the right damper. The left cushion unit is constituted of only the left damper and does not include the compression coil spring and hence, the suspension structure can be simplified. Further, in the left cushion unit, the left damper does not slide relative to the compression coil spring in performing a stroke and hence, no friction is generated.Type: GrantFiled: April 15, 2008Date of Patent: June 12, 2012Assignee: Honda Motor Co., Ltd.Inventors: Tomohiro Fuse, Kazuhiko Gogo

Patent number: 8167328Abstract: A suspension system for a handlebar-steered vehicle includes an upper tube, a lower tube reciprocally slidable relative to the upper tube. A positive spring assembly biases the upper and lower tubes away from each other. A piston assembly is attached to the lower tube. The suspension includes a travel adjustment mechanism including a locking mechanism and an actuator. The locking mechanism is connected to the positive spring assembly and selectively maintains a first portion of the positive spring assembly in a compressed state with the upper and lower tubes drawn toward each other. The actuator is operatively connected to the locking mechanism to releasably engage the locking mechanism to maintain the first portion of the positive spring assembly in the compressed state.Type: GrantFiled: September 16, 2010Date of Patent: May 1, 2012Assignee: SRAM, LLCInventors: Robert Powell, James Osbourne

Publication number: 20120098233Abstract: In accordance with the present invention, an improved bicycle frame according to one embodiment of this invention has a top tube that allows the wheel base to lengthen by resiliently flexing or pivotally deflecting vertically while resisting torsional flex This feature is combined with a resilient, flexible, arcuate down tube extending between the bottom bracket of the bicycle and the bicycle head tube or the intermediate connection points The down tube has at least one arc and springs back to its original position from forces of tension as well as compression The combination of the two flexing members gives the bicycle a smoother ride and may also enhance the delivery of pedal” power to the rear wheel The down tube is replaceable in order to modify the flex characteristics of the frame and physical characteristics, such as head tube and seat tube angle, wheel base, and bottom bracket height.Type: ApplicationFiled: June 28, 2010Publication date: April 26, 2012Inventor: Mark L.
