Patent number: 11668386Abstract: A pulley structure may be equipped with an outer rotating body, an inner rotating body, and a coil spring provided between the outer rotating body and the inner rotating body. The coil spring is configured so as to undergo torsional deformation in a diameter-expanding or a diameter-contracting direction, thereby engaging the outer rotating body and the inner rotating body and transmitting torque, and to undergo torsional deformation in the direction opposite the direction in which torque is transmitted, thereby entering a disengaged state in which the coil spring slides with the outer rotating body or the inner rotating body, thus interrupting the transmission of torque. The number of windings of the coil spring is in a range between [M-0.125] and M (both inclusive), where M is a natural number.Type: GrantFiled: April 17, 2018Date of Patent: June 6, 2023Assignee: Mitsuboshi Belting Ltd.Inventors: Hayato Shimamura, Katsuya Imai, Ryosuke Dan, Takashi Morimoto

Patent number: 11623712Abstract: A mechanism and method for externally adjusting the mid-valve stiffness is described and enables adjustment of a mid-valve functionality without disassembly of a suspension system incorporating the invention. The effect of this adjustment on the damping curve is far greater than either low-speed compression adjusters or conventional high-speed compression adjusters. The apparatus combines the valve-stiffening system of a high speed compression adjuster with the sensitivity of the mid-valve. Externally accessible adjustment members are operatively coupled to the mid-valve components located internally in a fork so that manipulation of the adjustment members causes adjustment of the mid-valve and the damping force created by the mid-valve. The apparatus may be utilized in closed cartridge suspension forks (CCSF) and open cartridge suspension forks (OCSF) and other shocks or suspension dampers.Type: GrantFiled: May 9, 2021Date of Patent: April 11, 2023Assignee: KREFT, LLCInventor: Adam Krefting
