发明名称 SOFT TIPPED POLE AND BRAKING SYSTEM FOR RECREATIONAL USE
摘要 Soft-tipped pole designs and methods for their use on pavement are disclosed. The soft, gripping pole tip can slow down a roller skier or skateboarder by slowing down the rider directly and by providing increased rider stability during breaking. This is accomplished by the rider pressing one or two pole tips against the pavement, with or without the use of a fulcrum point for increased leverage. The soft rubberlike tip has a large surface area that provides durability as well as variable levels of frictional force imparted against the pavement. The fulcrum for the pole can be the user's arm or leg as well as fulcrum element fastened to the rolling device.

主权项 1. A method of braking a human powered rolling vehicle on pavement comprising: manually grasping a soft tipped pole comprising a soft elastomeric tip; pressing the soft tip against the pavement to effect braking; varying the force of the soft tip against the pavement by engaging the soft tipped pole against a fulcrum surface to vary the braking force.
