发明名称 BATTING SKILLS DEVELOPMENT DEVICE
摘要 <p>A batting skills development device for use with a bat, the bat generally having a proximal handle portion and a distal barrel portion with a tapered section extending therebetween. The device comprises, in an exemplary embodiment, a weighted sleeve having a tapered inner surface configured for approximating the tapered section of the bat, with a first end of the sleeve having a first inner diameter larger than a second inner diameter of an opposing second end of the sleeve, the first inner diameter being less than or equal to a barrel diameter of the barrel portion. Thus, during use, the sleeve is slipped over the handle portion of the bat and wedged against the tapered section proximal the barrel portion, thereby maintaining a balanced distribution of weight along the bat while allowing the barrel portion to remain substantially unobstructed.</p>
