Athletic swing plane indicator

Abstract

The invention disclosed is an athletic swing plane training device used as a baseball bat swing plane visual indicator.

1 ) An athletic swing plane visual indicator comprising:
 a. a housing tapered to fix itself into position over a baseball bat with a simple sliding motion;   b. an at least one battery;   c. a switching circuit to connect and disconnect indicator light emitting diodes (“LEDs”) to at least one battery;   d. an at least one current limiting circuit;   e. and a number of indicator light emitting diodes equally spaced around the housing.   f. wherein the switching circuit is configured to detect initiation of the motion to generate illumination via the indicator light emitting diodes to define a path of illumination as a visible streak in a plane through which the housing traverses.   
     
     
         2 ) The invention in  claim 1 , wherein said switching circuit is a manual switch recessed in said athletic swing plane visual indicator housing, but accessible to the user. 
     
     
         3 ) The invention in  claim 1 , wherein said switching circuit is an automatic centrifugal switch embedded in said athletic swing plane visual indicator housing and not accessible to the user when being used and configured to automatically engage during motion of the housing, the motion coinciding with the motion of the baseball bat. 
     
     
         4 ) The invention in  claim 1 , wherein said switching circuit is an automatic switch based on accelerometers embedded in said athletic swing plane visual indicator housing and not accessible to the user when being used and configured to automatically engage during motion of the housing, the motion coinciding with the motion of the baseball bat. 
     
     
         5 ) An athletic swing plane visual indicator comprising:
 a. a housing tapered to fix itself into position over a baseball bat with a simple sliding motion;   b. an at least one battery;   c. a switching circuit to connect and disconnect the indicator light emitting diodes (“LEDs”) to at least one battery;   d. an at least one current limiting circuit;   e. a timing circuit designed to keep said indicator light emitting diodes (“LEDs”) illuminated for a period of time, such as ten seconds, after said athletic swing plane visual indicator is swung;   g. wherein the switching circuit is configured to detect initiation of the motion to generate illumination via the indicator light emitting diodes to define a path of illumination as a visible streak in a plane through which the housing traverses.   
     
     
         6 ) The invention in  claim 5 , wherein said switching circuit is a manual switch recessed in said athletic swing plane visual indicator housing, but accessible to the user. 
     
     
         7 ) The invention in  claim 5 , wherein said switching circuit is an automatic centrifugal switch embedded in said athletic swing plane visual indicator housing and not accessible to the user when being used and configured to automatically engage during motion of the housing, the motion coinciding with the motion of the baseball bat. 
     
     
         8 ) The invention in  claim 5 , wherein said switching circuit is an automatic switch based on accelerometers embedded in said athletic swing plane visual indicator housing and not accessible to the user when being used and configured to automatically engage during motion of the housing, the motion coinciding with the motion of the baseball bat. 
     
     
         9 ) An athletic swing plane visual indicator comprising:
 a. a housing constructed of a plastic with semi-rigid properties that allows said athletic swing plane visual indicator to conform to the shape and diameter of a given athletic bat size;   b. a timing circuit designed to keep said indicator light emitting diodes (“LEDs”) illuminated for a period of time, such as ten seconds, after said athletic swing plane visual indicator is swung;   c. at least one battery;   d. switching circuit to connect and disconnect the indicator light emitting diodes (“LEDs”) to at least one battery;   e. at least one current limiting circuit;   f. a number of indicator light emitting diodes (“LEDs”) equally spaced around the housing;   h. wherein the switching circuit is configured to detect initiation of the motion to generate illumination via the indicator light emitting diodes to define a path of illumination as a visible streak in a plane through which the housing traverses.   
     
     
         10 ) The invention in  claim 9 , wherein said switching circuit is a manual switch recessed in said athletic swing plane visual indicator housing, but accessible to the user. 
     
     
         11 ). The invention in  claim 9 , wherein said switching circuit is an automatic centrifugal switch embedded in said athletic swing plane visual indicator housing and not accessible to the user when being used. 
     
     
         12 ). The invention in  claim 9 , wherein said switching circuit is an automatic switch based on accelerometers embedded in said athletic swing plane visual indicator housing and not accessible to the user when being used and configured to automatically engage during motion of the housing, the motion coinciding with the motion of the baseball bat.
