Swimmer's kickboard with speedometer

Abstract

A swimmer's kickboard comprising a speedometer and display, such that the speed of the kickboard's passage through the water may be measured and conveyed to the user.

1 . A swimmer's kickboard device comprising a speed measuring means to determine the rate of travel of the kickboard through water and a speed display means to visually display the rate of travel of the kickboard through the water.  
   
   
       2 . The device of  claim 1 , wherein said speed measuring means comprises a propeller.  
   
   
       3 . The device of  claim 2 , wherein said propeller is mounted onto a rotating shaft pivotally mounted to said kickboard, whereby the axis of rotation of said shaft is not maintained in a fixed orientation relative to said kickboard.  
   
   
       4 . The device of  claim 2 , wherein said propeller is visible to a user when the device is propelled through water.  
   
   
       5 . A swimmer's kickboard device comprising: 
 a main body composed of a buoyant material, said main body having an upper surface, a lower surface, sides and a rounded nose;    speed measuring means to determine the speed of the device as it is pushed through water; and    speed display means to display the speed of the device measured by the speed measuring means as the device is pushed though water.    
   
   
       6 . The device of  claim 5 , wherein said speed measuring means comprises a propeller mounted to said lower surface of said main body.  
   
   
       7 . The device of  claim 6 , further comprising brace members and a propeller shaft, wherein said propeller is mounted on said propeller shaft and said propeller shaft is mounted on said brace members.  
   
   
       8 . The device of  claim 7 , wherein said propeller shaft is mounted to said brace members in a pivoting manner, whereby the axis of rotation of said propeller shaft may vary relative to said lower surface dependent upon the orientation of the main body relative to the surface of the water.  
   
   
       9 . The device of  claim 8 , further comprising a guard member disposed about said propeller.  
   
   
       10 . The device of  claim 5 , wherein said speed sensing means comprises a propeller, and wherein said main body further comprises an opening extending from said lower surface to said upper surface, and wherein said propeller is mounted within said opening.  
   
   
       11 . The device of  claim 10 , further comprising a transparent cover disposed over said propeller on said upper surface.  
   
   
       12 . The device of  claim 11 , further comprising bore members passing through said main body whereby water is delivered through said bore members to said propeller.
