  • Patent number: 6315085
    Abstract: A semi automatic brake applicator for wheel chairs which have at least one arm with an actuator lever pivotally attached to the arm, an actuator rod pivotally attached to the actuator lever at the first of two ends and to a clamp at the second end, the clamp being attached to the brake actuator lever of the wheel chair brake system. In operation, the actuator lever is rotationally pivoted which causes the actuator rod to move linearly which, in turn, causes the clamp to rotate the brake actuation handle thereby bringing the brake shoe into contact with the drive wheel thus setting the brake. Reverse motion of the actuator lever causes the brake to release.
