Abstract

A novel swing speed training weight that is a composite plastic helical coil adapted to slidably attach to a bat used in the sport of baseball and softball.

Claims

exact text as granted — not AI-modified
1 . A weight training aid comprising a composite plastic in the shape of helical coil that slidably attaches to a swingable sport object selected from the group consisting of a baseball bat and a softball bat.  
   
   
       2 . A weight training aid as claimed in  claim 1  in which the helical coil is pre-formed by shape and size for attachment to the swingable sport object.  
   
   
       3 . A weight training aid as claimed in  claim 1  in which the helical coil can be loosened and slidable to a new attachment location.  
   
   
       4 . The weight training aid as claimed in  claim 1  wherein the cross-sectional shape of the helical coil is rectangular.  
   
   
       5 . A weight training aid as claimed in  claim 4  wherein the inside coil surface of the device and the outside surface of the bat are in close contact to maximize slip resistance.  
   
   
       6 . A weight training aid as claimed in  claim 4  wherein a vertical smooth cut of matching edges between the coil segments provides frictional locking to strengthen the attachment of the weight training aid to the swingable sport object.  
   
   
       7 . The weight training aid as claimed in  claim 1  wherein the helical coil is a composite of a rigid elastic plastic core imbedded in the flexible viscoelastic plastic walls of the coil.  
   
   
       8 . The weight training aid as claimed in  claim 7  wherein the elastic plastic core is a rigid plastic providing grip strength for the attachment of the weight training aid to the swingable sport object.  
   
   
       9 . The weight training aid as claimed in  claim 7  wherein the viscoelastic plastic outer layer is a flexible plastic for absorbing impact shock to retain attachment of the weight training aid to the swingable sport object when the swingable sport object is hit by a ball.  
   
   
       10 . The weight training aid as claimed in  claim 8  wherein the rigid plastic is polyvinyl chloride.  
   
   
       11 . The weight training aid as claimed in  claim 1  wherein the weight of the training aid is in the range of from one-half to ten ounces.  
   
   
       12 . The weight training aid as claimed in  claim 1  wherein the weight of the training aid is in the range of one to six ounces.  
   
   
       13 . The weight training aid as claimed in  claim 1  wherein the weight of the training aid is in the range of two to four ounces.
