Abstract
Abstract A bowler's adjustable wrist brace is made into a glove-like configuration. The brace enables the bowler to quickly and conveniently lock his wrist at various desired angles in order to control the "hook" or sidespin of the bowling ball. Bowling alley lane conditions vary. Even varying amounts of oil applied to the same lane can result in different paths for the same ball throw. This brace enables the bowler to adjust his wrist position for different lane conditions. Additionally, the bowler may achieve a different amount of hook on the same alley for various shots by simply adjusting a lever. A calibrated wrist angle indicator enables the bowler to repeat various desirable wrist positions for his different shots.
