Sport stick training weight

Abstract

A training weight for a sport stick is provided. The sport stick includes a housing having a sidewall, a proximal end wall and a distal end wall. The sidewall and proximal end wall include an opening and slot which are sized to accept a sport stick's handle and knob. Preferably, the training weight includes a cup which is biased by a spring to force the sport stick's knob to engage and lock to the training weight's proximal end wall. The training weight may include a cam mechanism to permit the retraction and extension of the spring and cup.

1 . A training weight for a sport stick having handle portion terminating in a radially extending knob, the training weight comprising:
 a circumferential sidewall forming a central conduit and having a proximal end and a distal end;   a distal end wall engaging and closing said sidewall's distal end;   a proximal end wall engaging said sidewall's proximal end, said sidewall, distal end wall, and proximal end wall forming a central cavity;   said sidewall having an opening adjacent said proximal end wall, said opening extending circumferentially to define said opening's width; and   a slot formed in said proximal end wall, said slot extending from said sidewall's opening radially inward to beyond the center of said proximal end wall.   
     
     
         2 . The sport stick and training weight combination of  claim 1  further comprising a spring located within said central cavity, said spring having a first end positioned at said distal end and a second end positioned to be axially movable within said cavity so as to bias a sport stick's knob in the proximal direction 
     
     
         3 . The sport stick and training weight combination of  claim 2  further comprising a cup engaging said spring's second end, said cup having a depression sized for receipt of a sport stick knob. 
     
     
         4 . The sport stick training weight of  claim 2  further comprising:
 a cam mechanism that will lock the cup in a retracted condition or permit the cup to extend to an extended condition; 
 a recess formed in said distal end wall; and 
 wherein said spring's first end and cam mechanism are positioned in said recess. 
 
     
     
         5 . A sport stick and training weight combination comprising:
 a sport stick having an elongate substantially cylindrical shaft having first and second ends, said sport stick having a circular knob affixed to said shaft's first end and said shaft having a handle portion adjacent to said knob, said knob's diameter being greater than said handle portion's diameter;   a training weight having,
 a circumferential sidewall forming a central conduit and having a proximal end and a distal end; 
 a distal end wall engaging and closing said sidewall's distal end; 
 a proximal end wall engaging said sidewall's proximal end, said sidewall, distal end wall, and proximal end wall forming a central cavity; 
 said sidewall having an opening adjacent said proximal end wall, said opening extending circumferentially to define said opening's width; and 
 a slot formed in said proximal end wall, said slot extending from said sidewall's opening radially inward to beyond the center of said proximal end wall, said proximal end's slot having a width greater than said sport stick's handle's diameter but said slot's width smaller than said sport stick's knob's diameter, and said sidewall's opening's width being greater than said proximal end's slot's width and greater than said sport stick's knob's diameter. 
   
     
     
         6 . The sport stick and training weight combination of  claim 5  further comprising a spring located within said central cavity, said spring having a first end positioned at said distal end and a second end positioned to be axially movable within said cavity, and said sport stick's knob positioned within said cavity with said spring's second end biasing said sport stick's knob in the proximal direction 
     
     
         7 . The sport stick and training weight combination of  claim 6  further comprising a cup engaging said spring's second end, said cup having a depression sized for receipt of a sport stick knob. 
     
     
         8 . The sport stick training weight of  claim 6  further comprising:
 a cam mechanism that will lock the cup in a retracted condition or permit the cup to extend to an extended condition; 
 a recess formed in said distal end wall; and 
 wherein said spring's first end and cam mechanism are positioned in said recess.
