ABSTRACT:
A hand-held braking device for use with foot-mounted wheeled vehicles such as in-line skates, rollerskates, skateboards, roller skis, and other similar wheeled vehicles designed to control speed or to stop quickly in a short distance. The device consists of a pole whose length is approximately 90% of the height of the user. The top end has a handle; the center has a foam rubber hand grip; the bottom end has a brake pad assembly. The brake pad assembly comprises a front and a back trapezoid plate fastened to the bottom end of the pole, between which is fastened a replacable trapezoid pad of rubber or similar material, The rubber pad is approximately twice as large as the two plates and extends below the lower edges of the two plates. The rubber pad and the two plates are both curved to form a scoop, The bottom 6 to 8 inches of the pole is bent in a curve at approximately a 20' angle to the upper end of the pole. Speed control or stopping is caused by friction between the ground surface and the rubber pad, The rubber pad engages the ground either by being dragged from the rear or by being extended to the front on either the right or left side of the body. A third technique for engaging the ground surface is thrusting the brake pad assembly rearward between the legs and engaging the ground surface by "sitting" on the pole while holding the handle and the hand grip. The degree of braking is determined by the amount of pressure exerted downward on the rubber pad with the pole while being held with both hands.
