摘要： The present invention is a chain structure of bicycles, which comprises a plurality of rollers, a plurality of chain sheets and a plurality of chain rollers. Wherein the rollers define a mounting space. Each chain sheet comprises a chain body, a first pivot joint part extending from one end of chain body and to be arranged in the mounting space, a second pivot joint part horizontally extending from the other end of chain body, the second pivot joint part is installed on the roller with the first pivot joint part, wherein the first pivot joint part is in a horizontal position different from chain body, the first pivot joint part defines a rotation space for placing the second pivot joint part of another chain sheet, so that the first pivot joint part and second pivot joint part can rotate a preset angle in the rotation space. When the chain sheets are combined with rollers respectively, the chain bodies remain on the same plane, the chain roller penetrates the second pivot joint part and the first pivot joint part respectively for connecting the roller to the chain sheets on both sides of roller. Thereby, the chain is thinned and the weight is reduced, the tensile strength is increased by thickening the chain sheet.

摘要： A stepper scooter provides step pads that are connected to a laterally arranged rocker bar assembly. Vertical movement of the step pads causes the rocker bar assembly to reciprocally pivot which translates drive chains which cause rotation of the drive wheel or wheels. The rocker bar assembly comprises two four bar linkages between a center fork and each step pad. An alternate embodiment uses the rocker bar to reciprocally rotate a gear axle which drives a bevel gear arrangement to rotate the drive wheel or wheels via one-way bearings. Another embodiment incorporates a chain and sprocket drive between the bevel gear arrangement and the drive wheel or wheels, wherein the one-way bearings are replaced with a one-way sprocket drive. A stand is provided that is useful with any of the above scooter embodiments. The stand lifts the wheels of the scooter off the ground or floor by supporting a rear sprocket tube of the scooter to render the scooter effectively immobile during use. The scooter can be used as a stationary exercise device.

摘要： A carbon fiber toothed structure has a body. The body is circular and has a toothed segment and at least one carbon fiber cloth. The toothed segment is formed on an outer periphery of the body. The at least one carbon fiber cloth is deposited on a front side and a rear side of the body from a center to the outer periphery of the body to cover the toothed segment. The body is made by stacking multiple circular carbon fiber cloths of different diameters with each other. Some of the carbon fiber cloths deposited in the body have smaller diameters than those of the others of the carbon fiber cloths to enable the center of the body being thicker than the outer periphery of the body. The toothed segment has two guiding inclined planes respectively deposited on the front side and the rear side of the body.

摘要： A bicycle transmission apparatus comprises a base member, an input shaft, a first transmission member, a second transmission member, and a first coupling member. The base member is configured to be attached to a bicycle frame as a separate member from the bicycle frame. The first transmission member is rotatable relative to the base member about a first rotational axis different from the input rotational axis. The second transmission member is rotatable relative to the base member about a second rotational axis different from each of the input rotational axis and the first rotational axis. The first coupling member is configured to couple the first transmission member to the second transmission member to transmit rotation of the first transmission member to the second transmission member at a variable speed stage.

摘要： An object of the present invention is to provide a saddle-type vehicle which can switch between the parking brake state and the neutral state using a clutch actuator configured to operate the clutch and thus lower the manufacturing cost. According to the present disclosure, there is provided a saddle-type vehicle which can be driven by a driver sitting on a seat and steering a bar handle. The saddle-type vehicle can comprise a clutch arranged on a power transmitting path from a driving source to a wheel (or wheels) configured to selectively transmit a driving power of the driving source to the wheel and selectively cut off the transmission of driving power of the driving source; a transmission arranged on the power transmitting path configured to shift gears in accordance with the travelling state of the vehicle; and a clutch actuator comprising an electrically operated actuator configured to actuate the clutch, wherein the clutch can be switched by the clutch actuator between a parking brake state, in which the power transmission between the driving source and the driving wheel is performed under a stopped state of the driving source, and a neutral state, in which the power transmission between the driving source and the driving wheel is cut off.
