Spark pole

Abstract

A spark pole is useful for controlling the movement of a rider of a wheeled device over a skating surface, and for generating sparks as the rider moves with respect to the skating surface. The spark pole has a shaft with a handle at one end and a grinding head at the other end. The grinding head supports at least one spark-producing body that generates sparks when it frictionally engages a skating surface. The grinding head also has a grinding head for frictional engagement with the skating surface to control the rider's movement along the skating surface. The shaft is preferably telescoping and adjustable in length.

What is claimed is: 
     
         1 . A spark pole, comprising:
 a shaft having a first end and a second end;   a handle located at the first end of the shaft;   a grinding head located at the second end of the shaft;   at least one spark-producing body extending from the grinding head; and   whereby the spark pole is configurable for being held by a user to maintain balance and provide propulsion by contacting the at least one spark-producing body from the grinding head to a surface thereby creating sparks from frictional contact between the at least one spark-producing body and the surface.   
     
     
         2 . The spark pole of  claim 1 , wherein the grinding head further comprises a ground tip. 
     
     
         3 . The spark pole of  claim 1 , wherein the shaft further comprises:
 a first shaft member having an upper end and a lower end; and   a second shaft member having an upper end and a lower end;   wherein the lower end of the first shaft member engages the upper end of the second shaft member, the upper end of the first shaft member being the first end of the shaft, and the lower end of the second shaft member being the second end of the shaft.   
     
     
         4 . The spark pole of  claim 1 , wherein the at least one spark-producing body is a plurality of spark sticks. 
     
     
         5 . The spark pole of  claim 1 , wherein the shaft has a central axis that extends from the first end to the second end, and further wherein the at least one spark-producing body are cylindrical, each of the at least one spark-producing body having a central axis that is not parallel to the central axis of the shaft. 
     
     
         6 . The spark pole of  claim 1 , wherein the at least one spark-producing body comprises ferrocerium. 
     
     
         7 . The spark pole of  claim 3 , wherein one of the first and second shaft members is an outer telescoping member, and the other of the first and second shaft members is an inner telescoping member, the inner telescoping member being received in the outer telescoping member, the inner telescoping member being slidably received within the outer telescoping member. 
     
     
         8 . The spark pole of  claim 7 , wherein the inner telescoping member is securable in fixed spatial relation relative to the outer telescoping member in at least one position relative to the outer telescoping member.
