BALL BAT INCLUDING A STIFFENING ELEMENT IN THE BARREL

摘要

A ball bat includes a barrel in which one or more stiffening elements are located. The stiffening element may be positioned at a variety of locations, and may have a variety of configurations, for selectively limiting the barrel's performance without appreciably increasing the bat's moment of inertia. In one configuration, the stiffening element includes two radially outer flanges, a radially inner flange, and two web members connecting the outer flanges to the inner flange. The radially outer surfaces of the radially outer flanges contact, and may be affixed to, the inner surface of the barrel wall.

1. A ball bat, comprising:
a substantially hollow barrel having an inner surface; a handle attached to or integral with the barrel and extending from the barrel in a longitudinal direction; and a stiffening element in the barrel, the stiffening element including:
first and second longitudinally spaced base portions positioned against the inner surface of the barrel;a first radially inwardly protruding portion extending from an end of the first base portion to a first distal end;a second radially inwardly protruding portion extending from an end of the second base portion to a second distal end; anda longitudinal portion extending from the first distal end of the first radially inwardly protruding portion to the second distal end of the second radially inwardly protruding portion.
