ABSTRACT:
A manual braking mechanism is adapted for manually overridable remote conl. The mechanism is disposed in a generally planar region forward of a vehicle's handle bar that does not interfere with the vehicle body or a human vehicle driver. The mechanism includes a base plate releasably clamped to the vehicle's handle bar and a housing fixed on the base plate. A brake cylinder in the housing connects to a control lever swingable on the base plate about a lever axis, and the cylinder's reaction force biases the lever toward a brake releasing position. A link pivots on the plate at the lever axis, has a hinge connection remote from the lever axis and has a carrier closer to the lever axis to the hinge connection. The carrier cammingly rotates the lever as the link swings on the lever axis. The mechanism has a frame whose first leg connects to the base plate at the lever axis and the frame's second leg is releasably clamped to the handle bar. The clamps for the base plate and second leg can be loosened to turn the modified braking mechanism on the handle bar. A third leg of the frame pivotally supports one end of a motor unit while the motor unit's opposite end engages the link's hinge connection. An extensor translates into and from the motor unit to swing the link so that the lever may release or apply the vehicle brake. The hinged connection utilizes a manually removable quick release pin that allows rapid decoupling of the motor unit from the link, after which the motor unit can be swung free of the link.
