ABSTRACT:
It's a movable bowling wrist device that is secured to the back of the hand and forearm by means of straps and it consists of four main structural parts made of stainless steel. The hand portion with all its finger extensions and forearm portion are connected together by a wing type structure with an attachment of an adjustable stopping mechanism on top. The hand portion with all its finger extensions is indefinitely moving vertically perpendicular to the wing part from which it is connected can be indefinitely adjusted from left to right or vice versa on a horizontal plane on which it is attach to the forearm portion can be place in a locking position by a swiveling lock. The adjustable stopping mechanism stops the hand portion with all its finger extensions on a backward movement thus producing an angle perpendicular to the forearm portion. Thus the angle formed is not constant, it is merely restricted or limited in a position by the backward movement of the hand portion with all its finger extensions, an indefinite forward motion of the hand will automatically unrestrict the restricted angle formed and a greater angle will be taken into action. And the indefinite foward motion of the hand portion with all its finger extensions, can help the bowler cupp and uncupp, push to create additional or lesser rotation and revolution, from the restricted angle produced, to the ball freely without limitations during delivery and point of release.
