Abstract:
1. A bat weight for use on a bat having a knob end, a barrel end opposite the knob end and a taper defined along an outer surface between the knob end and the barrel end, the bat weight comprising: a) an elongated tubular sleeve comprising a longitudinal axis, a first opening at a first end, a second opening at a second end opposite the first end, a circumferential inner wall surface defined along the longitudinal axis between the first and second ends for positioning adjacent the bat outer surface, and a circumferential outer wall surface defined along the longitudinal axis between the first and second ends for assisting in the gripping and positioning of the sleeve relative to the bat; b) an enclosed interior defined between the inner and outer wall surfaces from the first end to the second end; c) an annular retainer ring secured within the enclosed interior proximate the first end for engaging the bat taper upon sliding advancement of the tubular sleeve across the bat outer surface from the knob end to the barrel end, the retaining ring fixing the dimension of the first opening such that the first opening is not adjustable relative to the bat; and d) at least one weight secured within the interior and spaced from the retainer; e) wherein centrifugal force during swinging of the bat seats the retainer against the bat taper.
