  • Patent number: 7340975
    Abstract: A bicycle control apparatus comprises a first position setting member having a plurality of first positioning members with a first pitch, an operating member that rotates relative to the position setting member, and a second position setting member structured to rotate with the operating member and to move axially. The second position setting member has a plurality of second positioning members with a second pitch, wherein the first pitch is different from the second pitch. The first pitch and the second pitch are set so that an engagement pitch between a first engagement position of the second position setting member and a second engagement position of the second position setting member that results from rotation of the operating member is less than both the first pitch and the second pitch.

  • Patent number: 7252300
    Abstract: Manual braking system with a variable braking force for a wheelchair. Caliper type brakes positioned to mount on and exert braking force on disks mounted to interior “disk” hubs rotatably mounted to the wheelchair frame wheel hubs are mated with the “disk” hubs with a push button release pin allowing the wheel to be quickly removed without disturbing disk braking system. Caliper brakes are actuated by a manual lever arm, cable and pulley combination mounted to the frame of the wheelchair. The lever is provided with and without a plunger mechanism. A plunger mechanism allows the user to maintain the manual braking force exerted on lever without hands. The plunger mechanism is fixably mounted and positioned to insert a plunger head into notches on the lever. The force exerted by the plunger head is sufficient to hold the plunger head within the notch and prevent movement of the lever without manual force.

  • Patent number: 7243762
    Abstract: A bicycle handbrake operating device is provided. The present invention utilizes a roller wheel to pull the brake wire so as to generate a longer pulling distance and to reduce the exerted force as well. The roller wheel is installed inside the handbrake operating device, and the brake wire goes around the roller wheel. When the operating lever is gripped, the brake wire slides along the roller wheel to achieve a longer pulling distance; the roller wheel's self rotation also reduces the exerted force. Additionally, the brake wire almost always remains a straight line during the pull, which makes the operation of the handbrake operating device smooth and the brake wire would undergo minimum wearing.

  • Patent number: RE39757
    Abstract: A brake lever arm is mounted to a base member, with the base member fixed to a bicycle handlebar. The lever arm is pivotal about a pivot point on the base. The lever arm includes an adjusting mechanism that adjusts the position of the lever arm when the lever arm is in a brake dis-engaged position. The adjusting mechanism is slideable in grooves in the lever arm such that the adjusting mechanisms may be moved to positions that are differing distances away from the pivot point. The adjusting mechanism includes a contact member that engages a brake cable connected to the lever arm when the lever arm is moved from the brake disengaged position toward a brake engagement position. The position of the contact member with respect to the pivot point determines the effect movement of the lever arm has on the cable. In this manner, the adjusting mechanism adjusts the length of the stroke or travel of the lever arm from the brake disengaged position to the brake engagement position.
