摘要： An improved sports racquet is provided having elements placed between the outer edge of the frame and the strings. The elements prevent the strings from touching the outer edge of the frame and rotate in response to a force applied in a direction generally perpendicular to the strings, thereby expanding the sweet spot, providing improved playability of the racquet, and significantly reducing the .[.fibration.]. .Iadd.vibration .Iaddend.that is transferred to the player's arm. The elements are preferably spherical in shape and may be comprised of various materials, including acetal, plastic and metal. The elements preferably rest in receptacles in the racquet frame, which may be integral with the frame or separate pieces, such as sleeves or grommets, that are connected to the frame. The receptacles are preferably designed to have a surface with substantially the same curvature as the bottom surface of the elements.

摘要： An improved sports racquet has elements placed between the outer edge of the frame and the strings. The elements prevent the strings from touching the outer edge of the frame and move in response to a force applied in a direction generally perpendicular to the strings, thereby expanding the sweet spot, providing improved playability of the racquet, and significantly reducing the vibration that is transferred to the player's arm. Each element has two connected seating portions that seat in receptacles in the outer perimeter of the racquet. Thus, two seating portions move together when a ball strikes the playing surface.
摘要翻译：改进的运动球拍具有放置在框架的外边缘和琴弦之间的元件。这些元件防止琴弦接触框架的外边缘并且响应于大致垂直于琴弦的方向施加的力而移动，从而扩展了甜点，从而提高了球拍的改进的可玩性，并且显着减少了振动转移到玩家的手臂。每个元件具有两个连接的座位部分，其位于球拍的外周的容器中。因此，当一个球撞击到游戏表面时，两个座位部分一起移动。

摘要翻译：提供了一种改进的运动球拍，其具有放置在框架的外边缘和琴弦之间的元件。这些元件防止琴弦接触框架的外边缘并响应于大致垂直于琴弦的方向施加的力而旋转，从而扩展了甜点，提高了球拍的可玩性，并显着降低了振动转移到玩家的手臂。这些元件的形状优选为球形，并且可以包括各种材料，包括缩醛，塑料和金属。元件优选地放置在球拍框架中的插座中，其可与框架一体或者连接到框架的单独的件，例如套筒或索环。容器优选设计成具有与元件的底表面基本相同的曲率的表面。
