Abstract: An improved device to aid bowlers in delivery of a bowling ball under varying conditions with a substantially uniform mode of delivery comprises a main brace having a hand end and a forearm end, with a pad bearing upon the forearm and a pad bearing upon the hand or wrist of the bowler, and a strap for securing the brace to the arm of the bowler, the hand end of the brace having at least one receiving portion for an auxiliary support or brace. In a preferred embodiment, the brace has at least one auxiliary finger or hand support or brace removably affixed to the main brace. There is further provided a palm or hand strap, with an optional ball riser, insertable between the palm or hand strap and the user's hand.

Abstract: A brace, limiting movement of the wrist of a user, is disclosed. A bar with padded supports bears on the back of the hand and the forearm of the user when the bar is secured to the arm of the user. The point at which the bar is secured to the arm is designed to operate as the fulcrum of a simple lever, thus amplifying the efficiency of the brace. An adjustable strap, with a releasable latch means, secures the bar to the arm of the user.
