  • Patent number: 9844720
    Abstract: A braking device is provided for an in-line skate where the braking device selectively alters the motion of the in-line skate depending upon the angulation of the in-line skate relative to a surface. As a user angulates or tilts the in-line skate, the braking device increasingly engages the surface to provide a braking force to alter the motion of the in-line skate.

  • Patent number: 9163681
    Abstract: A brake device includes a first member having holders, each of the holder configured to be in contact with a corresponding rolling body and hold the rolling body rotatably; a second member provided in contact with the rolling body and configured to rotate the rolling body in the holder according to a relative displacement with the first member; and a pressing mechanism configured to press the first member and the second member against each other. This makes it possible appropriately to set performance regardless of, for example, a projecting area of a surface of the first member, the surface being pressed by the second member.

  • Patent number: 7772730
    Abstract: The present invention provides a magnetic wheel including a foundation body, a cover body, a fly wheel, a central axis, a drive motor, a drive gear assembly and two magnetic control strips. The drive gear assembly is driven by an output axis of the drive motor, enabling the swinging of the gear wheel of two magnetic control strips. The drive gear assembly has a gearshift unit, a coupling element and rear gear. The axial direction of the coupling element and rear gear is the same as the central axis of the magnetic wheel. The gear wheel of two magnetic control strips is mated with the rear gear through spur gear, thus making it easier to improve the manufacturing precision and drive efficiency and also reduce the manufacturing cost for better economic efficiency.

  • Publication number: 20090127818
    Abstract: A bicycle includes a frame, a wheel mounted on the frame, a handlebar mounted on the frame, a damping device mounted on the frame and movable to touch the wheel, a control switch mounted on the handlebar, and a connecting wire mounted on the frame and connected between the control switch and the damping device to control movement of the damping device by operation of the control switch. Thus, when the bicycle travels downhill and the rear wheel is rotated at a higher speed, the damping device provides a damping force on the rear wheel to reduce the rotation speed of the rear wheel so as to prevent the rear wheel from being rotated at an excessive high speed when traveling downhill, thereby protecting the rider's safety.

  • Patent number: 7470220
    Abstract: A bicycle trainer is a bicycle-mounted apparatus used to produce friction to resist the turning of a wheel of a bicycle, thereby requiring the rider to exert more energy than would otherwise be necessary. The bicycle trainer is adjustable by the rider while riding, and can simulate hill or mountain climbing at any positive grade.

  • Patent number: 5887683
    Abstract: A braking device with brake adjusting devices disclosed for maintaining the proper spacing between the brake pad and the rim of the bicycle wheel or the brake disc attached to the bicycle wheel. Each of the brake adjusting devices preferably includes a spacing element and a support member which is coupled to the brake device. Of course, the support member can be coupled directly to the friction pad via a resilient biasing portion or coupled to various parts of the braking device. The spacing element is preferably biased against the rim or brake disc so as to apply a constant force thereto for obtaining the proper pad spacing when the braking device is in its release position. If a support member is used, the support member can have an attachment portion which is coupled to the brake shoe or friction pad support, a retaining member supporting the spacing element and a biasing portion located between the attachment portion and the retaining portion. Preferably, the spacing element is a roller or ball.

  • Patent number: 5411276
    Abstract: A roller skate brake for a roller skate having at least two rolling wheels mounted in-line. Each rolling wheel has a circumferential surface and is rotatably mounted to the roller skate about a rolling wheel axle. The brake includes a braking wheel also having a circumferential surface. The braking wheel is rotatably mounted about the roller skate about a braking wheel axle approximately parallel the rolling wheel axle. The braking wheel is mounted to the roller skate so that the circumferential surface of the roller skate wheel can be brought into contact with the circumferential surface of the rolling wheel. The brake also includes a braking lever for braking the rotation of the braking wheel when in contact with the rolling wheel, thus braking the rolling wheel. The circumferential surface of the rolling wheel is generally convex and the circumferential surface of the braking wheel may be generally concave.

  • Patent number: 5374071
    Abstract: A rolling device such as a roller ski or in-line skate that uses a roller of a hard material with the roller mounted to the frame of the roller ski or in-line skate in such a manner that it can be forcibly moved to contact the elastomeric wheel of the roller ski or in-line skate, causing the softer elastomeric material of the wheel to displace about the harder roller, resulting in a significant increase in rolling resistance with minimum frictional wear. A roller ski or in-line skate that uses, in conjunction with the aforementioned roller, a lever actuated brake permitting the roller ski or in-line skate to be stopped on down hill slopes.

  • Patent number: 4312514
    Abstract: A roller skate having a brake assembly attached to at least one wheel journal of the skate. The brake assembly has a brake member which may be selectively and adjustably brought to impart a frictional force against a wheel or wheels of the roller skate. This frictional force reduces the free rotatability of the wheel without otherwise adversely affecting the operational characteristics of the skate.

  • Patent number: 4033433
    Abstract: A body motion actuated, bicycle seat brake comprises a seat resiliently mounted on the seat tube of a bicycle such that at least the forward end of the mounting member may be deflected downwardly by the action of a rider shifting his weight forwardly relative to the mounting member forward end. A brake member is pivotably mounted at one end thereof to the forward end of the mounting member and is slidably mounted at an intermediate location thereof to at least the seat tube of the bicycle such that the distal end of the brake member is disposed in spaced proximity to the rear wheel when the forward end of the mounting member is in an undeflected position, and is urged into abutting, braking relationship with the rear wheel when the forward end of the mounting member is deflected. The seat may also be slidably mounted on the resilient mounting member.
