发明名称 APPARATUS FOR DETERRING MODIFICATION OF SPORTS EQUIPMENT
摘要 <p>The present invention relates to an apparatus for playing ball sports including softball. More particularly, the present invention relates to an apparatus for deterring the modification of ball bats. The bat comprises a barrel, a sweet spot, a transition area, a handle, and an end knob. Within the barrel are found supports used to reinforce the structural integrity of the bat to deter users from crushing the bat, causing the bat to fall outside the legal classification of bats allowed by the Amateur Softball Association of America (ASA). The supports are made out of a lightweight durable composition. The supports are held in place by a retaining member. Multiple supports and retaining members may be used.</p>
