发明名称 Ball bat
摘要 A ball bat includes a hollow handle segment, a wooden barrel segment and a reinforcing segment. The handle segment has a handle section, a connecting section that has an outer diameter smaller than that of the handle section, and an abutment section that is disposed between the handle and connecting sections. The barrel segment has an abutment end section, a top end section that is opposite to the handle section of the handle segment, and an insertion hole that extends from the abutment end section toward the top end section. The connecting section is inserted into the insertion hole. The abutment end section abuts against the abutment section. The reinforcing segment is sleeved on the abutment end section.

主权项 1. A ball bat comprising: a hollow handle segment extending along an axis, and having a handle section, a connecting section that is opposite to said handle section along the axis and that has an outer diameter smaller than that of said handle section, and an abutment section that is disposed between said handle and connecting sections; a wooden barrel segment extending along the axis, and having an abutment end section, a top end section that is opposite to said handle section of said handle segment along the axis, and an insertion hole that extends from said abutment end section toward said top end section along the axis, said connecting section of said handle segment being inserted into said insertion hole, said abutment end section abutting against said abutment section of said handle segment; a reinforcing segment surrounding the axis and sleeved on said abutment end section of said barrel segment; said barrel segment includes a surrounding wall having said abutment end section and said top end section, and an inner abutment wall surrounded by said surrounding wall and cooperating with said surrounding wall to define said insertion hole; said connecting section of said handle segment has a hollow end opposite to said handle section along the axis and formed with a plurality of angularly spaced-apart slits that extend in the direction of the axis; and said handle segment further has an expanding member inserted into said hollow end of said connecting section such that said hollow end of said connecting section is urged to expand radially and outwardly to abut tightly against an inner surrounding surface of said surrounding wall that faces said insertion hole.
