International Classification:

A63B 6900

US Classification:

273 54B

Abstract:

An athletic hand movement restricting device intended for attachment to the forearm and wrist of a bowler. The intent of the device is to restrict the said bowler's hand from rotating inwardly over on top of the bowling ball into an undesireable release position, and when the said device is secured into position on the said bowler's forearm and wrist, the said device restricts the said bowler's hand from rotating inwardly past a pre-selected position, but will allow a full unrestricted rotation of the said bowler's hand in an outwardly direction. The amount of restriction can be increased by the said bowler, previous to the said bowler's turn to play, through the use of a movable adjustment means. The said bowler's wrist is free to flex in all four planes while the said device is in position and while the said device is in use. The said device comprises two adjustable means; a wrist means and a forearm means, which secure a hinged plate assembly to the said bowler's forearm and wrist in a manner that will allow the said bowler's hand to rotate outwardly to an open position, but the said device will restrict the said bowler's hand from rotating inwardly into an incorrect closed position before the release of the said bowling ball.
