摘要： A racket sport teaching aid device comprises a frame that includes a pointing member. Unexpectedly good results are achieved when a weight is attached to the lower end of the frame. The weighted frame physically maintains the face of the racket perpendicular to the plane of the ground at both the back swing and at the ball impact point. The weighted frame serves the triple functions of stabilizing the head of the racket at the time of impacting the ball, of maintaining the head of the racket at a proper angle with respect to the ground, and of providing a directional guide to be visually observed by the player. This helps the player both to remember to maintain the racket head at impact at a proper angle with respect to the ground and actually physically assists the player in performing this task. The device also assists the player in following through on the stroke such that the follow-through is up and in the direction of the intended shot. The device accomplishes this effect because the pointing member serves as a visual guide which points to the intended target point at completion of the stroke.

摘要： A variable balance racket has a weight moveable from an inactive or rest position near the grip of the handle to an active position adjacent the head of the racket to increase the striking force of the head. The weight can be moved to the active position and held in this active position by a retainer, against the action of an elastic element which returns the weight to the rest position. The weight is released in response to the centrifugal force of the swing of the racket so it is automatically returned to the rest position before the next swing. This arrangement enables the player to move the weight to the active position prior to a serve or anticipated smash, while returning the weight to the rest position after such a swing for normal play or repositioning in the active position by the player.
摘要翻译：可变平衡球拍具有可以从手柄的手柄附近的不活动或静止位置移动到与球拍头部相邻的活动位置的重量，以增加头部的打击力。重量可以移动到活动位置，并通过保持器抵抗弹性元件的作用而保持在该活动位置，弹性元件使重量恢复到静止位置。响应于球拍的摆动的离心力释放重物，使得其在下一摆动之前自动返回到静止位置。这种布置使得玩家能够在作战或预期的粉碎之前将重量移动到主动位置，同时在这样的摆动之后将重量返回到休息位置，以便玩家正常地播放或重新定位在主动位置。

摘要： The present invention relates to a tennis racket accessory that adds weight at a selected position on a tennis racket and allows the player to position and remove the weight on tennis rackets of different sizes. The weight holder is made of a flexible material that wraps around a tennis racket handle and overlaps at the ends. The holder comprises two, spaced pockets with a weight in each pocket. The weights are in the shape of a cylinder. Each of the pockets are of sufficient size to permit its weight to roll along the holder lengthwise dimension over a distance that permits the weights to be moved by hand to opposite sides of the racket handle, and movable angularly to line up with the direction of the respective racket handle side.The holder includes means to fasten the ends together after it has been wrapped around the racket handle. The weights can be tightly pressed against the racket handle sides and the holder retained on the racket handle. The invention further provides method for placing the weight holder on the racket and a method for placing the weight holder on the racket to retain the racket feel.

摘要： Attachable and detachable weights are applied to a racket frame at a distance from the geometric axis that passes through the center of the racket handle, in such a manner as to adjust and increase the racket''s moment of inertia about that axis for normal play, and to alter the weight and the head-to-handle balance of the racket for normal play. This unique placement of the weights increases the effectiveness of the weights.
