Publication number: 20240051333Abstract: A spoke includes an axle body and two connecting elements. The axle body has a middle segment and two connecting segments. The two connecting segments are respectively connected to two opposite sides of the middle segment. The two connecting segments each have a first peripheral surface, and the two first peripheral surfaces each are formed with a friction enhancing structure. The two connecting elements respectively wrap at least a part of the two friction enhancing structures by means of injection molding. The two connecting elements each have a second peripheral surface facing away from the axle body, and the two second peripheral surfaces each are formed with a connecting structure.Type: ApplicationFiled: August 9, 2022Publication date: February 15, 2024Inventor: WEI-CHIH WEI

Patent number: 11845508Abstract: A bicycle headset includes a fixed member, wherein the headset is fixed onto a headtube of a bicycle via the fixed member. A steerer tube of a fork passes through the headtube and is connected to a fork portion. The fixed member has a first contour including a first guiding section, a second section, and a joint section that connects the first section and the second section and is located at the highest site among the first contour. A rotating member is fixed onto the steerer tube. A movable member is disposed onto the rotating member and is movable along an axial direction of the steerer tube. An elastic member urges the movable member to allow a second contour of the movable member to constantly touch the first contour of the fixed member, thereby preventing a stem connected to the steerer tube from overly turned and assisting to steer back.Type: GrantFiled: July 19, 2021Date of Patent: December 19, 2023Assignee: TIEN HSIN INDUSTRIES CO., LTD.Inventor: Wei-Chih Wei

Publication number: 20230382486Abstract: A bearing seat suitable for receiving a bearing includes an annular body, a first outer-radial flange and a second outer-radial flange. The annular body includes a peripheral wall. The peripheral wall has a first end, a second end, an inner matching surface and an outer surface. A thickness difference of the peripheral wall from the first end to the second end is within 30%. A portion of the inner matching surface is suitable for contacting and matching with an outer matching surface of the bearing. The first outer-radial flange protrudes from the outer surface adjacent to the first end and extends to the first end. The second outer-radial flange protrudes from the outer surface adjacent to the second end and extends to the second end. The overall structure of the bearing seat is uniform, which can reduce warpage and deformation caused by uneven shrinkage during the injection process.Type: ApplicationFiled: May 24, 2022Publication date: November 30, 2023Inventor: WEI-CHIH WEI

Patent number: 11543313Abstract: A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a handlebar of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the handlebar detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.Type: GrantFiled: June 23, 2020Date of Patent: January 3, 2023Assignee: TIEN HSIN INDUSTRIES CO., LTD.Inventors: Meng-Hua Chiang, Wei-Chih Wei

Patent number: 11536622Abstract: A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.Type: GrantFiled: June 23, 2020Date of Patent: December 27, 2022Assignee: TIEN HSIN INDUSTRIES CO., LTD.Inventors: Meng-Hua Chiang, Wei-Chih Wei
