摘要： A game racket with adjustable string tension includes a yoke in the throat portion of the racket to which main strings may be secured that engages opposed inside portions of the frame in the throat at upper and lower opposed pairs of points. A tension member secured between the yoke and handle portion of the racket is adjustable in length as an adjusting screw is rotated to control the position of the yoke in the throat and the main and cross string tension.

摘要： Provided is a racket including a head portion connected to a handle portion. The head portion includes a beam including string holes and at least one string looped through the string holes, the racket further includes at least one tensioning device rotatably arranged on a support surface on the exterior surface of the beam relative to which it can be rotated between a first and a second position. The tensioning device includes a through hole arranged parallel and offset to the rotation axis and extending through the tensioning device. The at least one string is looped from a first string hole through the through hole to a second string hole, so that the tension of the at least one string can be varied by rotation of the tensioning device between the first and second position, and where the outer circumference of the tensioning device further includes a mating surface for mating with the support surface. The mating surface extends from a first mating patch which contacts the support surface in the first position to a second mating patch which contacts the support surface in the second position and where the cross section of the mating surface perpendicular to the rotation axis has an arched shape.

摘要： The present invention provides a game racquet including an integrated circuit capable of supporting a low-voltage energy current. An embodiment of the invention provides a game racquet including one or more enhancements attached or integrated on the racquet frame. These enhancements may include but are not limited to: one or more LEDs, a sound amplification device, and an electromagnetic vibration emitter. In a further embodiment, the game racquet responds electronically to ball impact on at least one of the strings, and subsequently performs and action or actions including but not limited to making a sound or sounds, triggering lights, triggering LEDs, triggering another type of automation on the racquet such as a vibration emitter within the handle. The game racquet frame comprising at least one string channel in the frame head, bridge, or other area, which houses an actuator responds mechanically to a string movement triggering electronic connection.

摘要： Performance of a racket can be adjusted. A racket includes a grip, an annular frame that is provided with a plurality of through holes that penetrate from an inner circumferential face to an outer circumferential face, and a shaft that connects the grip and the frame in a shaft axis direction, the frame having a rear end side attachment part, on the outer circumferential face of the frame and on a side closer to the shaft in the shaft axis direction, where there is mounted a rear end side attachment to which a string tensely provided to the frame is routed, and the rear end side attachment being made of a material different from the frame.

摘要： A devise that enables the conversion of any sports racquet, such as a tennis racquet or a squash racquet, from a conventional “single-strung” configuration to a “dual-strung” configuration without altering or making any changes to the racquet frame itself. Whereas all embodiments to date for the dual stringing of a sports racquet utilize a specialized racquet frame specifically designed to accommodate or provide for the two generally parallel planes of crisscross strings that comprise the two playing surfaces, this invention requires no such specialized frame or alteration to the existing frame. The invention consists of an inner conversion ring that is used in conjunction with, or as an accessory to, any conventional racquet frame and permits said conventional frame to be “dual-strung” yielding two playing surfaces of generally parallel planes of crisscross strings. The conversion ring itself can be made of any rigid or semi-rigid material such as wood, plastic, metal, rubber or composite material. It is shaped and sized to fit within the more or less oval frame structure of the racquet head. The thickness of the ring can be varied and determines the separation between the two string playing surfaces. The racquet is then strung twice, using conventional techniques, so that the strings pass over each side of the conversion ring that acts as the separator between the two playing surfaces. Different string tensions and/or different sting types may be used for the playing surface on each side of the separation ring. This permits any ordinary sports racquet to be further tailored to the player's forehand and backhand.

摘要翻译： 将诸如网球拍或壁球拍的任何运动球拍从传统的“单列”配置转换成“双排”配置的设计，而不改变或对球拍框架本身进行任何改变。 尽管迄今针对运动球拍的双重穿线的所有实施例都使用专门设计用于容纳或提供包括两个游戏表面的十字形串的两个大致平行平面的专门的球拍框，但是本发明不需要这样的专门框架或改变 现有的框架。 本发明包括与任何常规球拍框架结合使用或作为附件使用的内部转换环，并且允许所述常规框架“双重”产生大致平行的十字形平行平面的两个游戏表面。 转换环本身可以由任何刚性或半刚性材料制成，例如木材，塑料，金属，橡胶或复合材料。 它的形状和尺寸适合在球拍头的或多或少椭圆形的框架结构内。 环的厚度可以变化并且确定两个串游戏表面之间的间隔。 然后使用常规技术将球拍串联两次，使得琴弦通过作为两个演奏表面之间的分隔符的转换环的每一侧。 不同的弦张力和/或不同的刺刺类型可以用于分离环的每一侧上的游戏表面。 这允许任何普通的运动球拍进一步适应玩家的正手和反手。
