Flexible Control Element Patents (Class 74/489)
  • Patent number: 4838113
    Abstract: A throttle mechanism for a vehicle employing a handle grip for steering where the throttle lever is controlled by manual actuation. A shield plate may be provided on the throttle lever to physically block the air flow against the vehicle from flowing directly over the operator's thumb actuating the throttle. Heating elements may be provided to heat a cover on the throttle lever which in turn heats the driver's hand. Heat controlling circuits to effectively reduce the heating input at high temperatures, multiple circuits for both rapid and slow heating and circuitry associated with the vehicle lighting switches may be employed.

  • Patent number: 4819497
    Abstract: A fast opening arrangement for shoes of bicycle brakes--of the type wherein control is obtained, by cable, through a control lever pivotally mounted on a body fixed to the bicycle handle bar--comprises a cylinder inserted across the control lever and axially moving through the same between two positions, which alternatively rest with their lateral surface against one or the other of the two sidewalls of the body on which said lever is pivotally mounted. These walls project to different extents and are cam profiled. In one of the two positions, the brake shoes are close to but spaced from the tire for normal braking; but in the other position, the shoes are spaced far enough apart to permit the wheel to be removed from between them.

  • Patent number: 4817452
    Abstract: The invention provides a simple method for reducing the amount of force required to actuate a motorcycle clutch. A miniature, lightweight housing means provides a pivot for a lever means to which is attached a short cable from the clutch actuation handle and also the original cable from the clutch. Because the two cable attachment points on the lever means are staggered, the lever means provides mechanical advantage and thereby reduces the manual force required to move the clutch actuation handle.The invention is designed to allow fast installation by providing cable slots in all parts and using cable sleeve tension to permit simple hook-on attachment of cable terminal hardware to the lever means. The housing means cover is used to exclude the environment and also to assure mechanical strength. The pivot pin and attachment hardware for anchoring the cables is locked into place by the covers.

  • Patent number: 4815330
    Abstract: A speed-change operating device for a bicycle includes an operating lever for actuating a derailleur, the operating lever being supported rotatably through a lever shaft to a base member attached to the bicycle frame. A friction mechanism applies to the lever an adjustable rotational resistance against a bias force of a return spring associated with the derailleur. A positioning mechanism includes a positioning member having a plurality of engaging portions for precisely setting the respective speed change stages of the derailleur and an engaging member engageable with at least one of the engaging portions. An operating mechanism selects between an operating mode and a non-operating mode of the positioning mechanism so that the positioning mechanism can be placed in a non-operating mode, when desired, with the speed-change operation being performed in such non-operating mode only with the friction mechanism resisting the return spring.
