Karl-Joachim Kuhne has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9103392
    Abstract: A control mechanism for decoupling a drive ratchet on a bicycle hub makes it possible to push the bicycle backwards while the foot pedals of the pedal crank drive remain still. These functions can be applied to folding bicycles, in which pedal movements are harmful when in their folded up state. The control mechanism includes a controlling sleeve coupled to the drive ratchet, which is indirectly connected by means of a frictional device to the unmoving hub axle.
    Type: Grant

  • Patent number: 8100242
    Abstract: The present invention provides a bicycle wheel hub that generally includes an axle, an input sprocket, an output shell, a one-way clutch and a locking mechanism. The one-way clutch operatively connects the input sprocket and the output shell and is configured to drive the output shell in a first direction. The locking mechanism is configured to operatively connect the output shell and the input sprocket to drive the output shell in a second direction to operate the bicycle wheel hub in a fixed drive mode. The locking mechanism is configured to operatively disconnect the output shell and the input sprocket to operate the bicycle wheel hub in a freewheel drive mode.

  • Patent number: 5916329
    Abstract: A casing for accommodating an operating pull for the purpose of attaching the operating pull to a bicycle gear, especially to a multiple-gear hub with a shifting wheel. The shifting wheel is placed, coaxially to the hub axis, at one of the ends of the hub. The shifting wheel is in contact with a control device that can be operated by the bicyclist during operation of the bicycle. The control device can include a remote-handling device that can be used by the bicyclist. The remote-handling device has a cable pull and a cable cover. The cable cover supports itself on the casing extension by an adjusting screw. The casing has a drive casing, for covering the shifting wheel, and a tubular casing extension, for accommodating the cable pull and an operating pull. The drive casing is connected to the casing extension by a joint with a cable guide. A spring storage and a coupling can be accommodated in the casing extension.

  • Patent number: 5810139
    Abstract: A friction device for controlling a clamping roller coupling for a drive device or for a back-pedal brake device connected to a bicycle hub can include a driving link with an ascending surface profile, at least one roll, a cage ring with cage arms, and an output link. The output link can be a brake jacket of the brake device. The brake device can be actuated by pedalling backword to tighten a friction spring on the hub axle. The friction spring can be realized as a loop spring, and a freewheel can be connected between the loop spring and the cage ring. The freewheel can include a first notch element non-rotatably connected to the cage ring, and a second notch element non-rotatably connected to the loop spring. When pedaling in the normal direction of rotation, the first and second notch elements are disengaged and torque is not transmitted to the loop spring.

  • Patent number: 4333627
    Abstract: An arrangement for imparting different adjustable directional movements to an object includes a number of adjusting gear assemblies each corresponding to one of different adjustable directional movements. Each adjusting gear assembly includes a gear housing, a worm and a worm gear both supported in the housing in meshed engagement with each other. The arrangement also includes a first motion transmitting mechanism for driving the worm and a second motion transmitting mechanism for connecting the worm gear to the object to adjustably move the object when the worm gear is driven by the worm. The gear housings of the adjusting gear assemblies are constructed substantially identical.
