摘要： A sports racquet having a plurality of string port holes and conventional string holes is formed of a single tube of prepreg material. When molded, mold elements press opposed portions of the prepreg tube into contact with one another, and shape the adjoining prepreg material into a string port hole blanks. The portion of the pressed-together material which initially blocks the string port hole is removed after molding so that the string port holes extend through the frame. Alternatively, the mold elements cause the prepreg tube to follow a serpentine shape, thereby defining string port holes which are open alternately along the top and bottom surface of the frame. A pair of cover rings may be secured to the top and bottom racquet surfaces to cover the open sides of the string port holes.

摘要： A sports racket frame with improved string holes includes a predetermined number of insertion pins pre-arranged in the molding cavity. The inner wall surface of the molding cavity adjacent to each insertion pin is filled with the fiber cement made of materials identical in quality with those making up the tubular strip used to form the racket frame. The sports racket frame so attained is composed of string holes which are integrally and simultaneously made with the racket frame as a unitary body and are provided with tubular support wall extending along the circumference thereof to reinforce the structural strength of the racket frame.

摘要： A tennis racket frame is constructed primarily of an elongated hollow tube member having a wall thereof consisting essentially of a plurality of concentric layers of high tensile strength fibers impregnated and bonded together by binder resin, at least two of the layers being helical windings of opposite unidirectional hands, and the head portion of a racket frame having a groove molded therein to receive the loop portions of the strings in recessed relation to the surrounding surface areas of the frame. The frames are made by a method including the use of a special mandrel on which the layers of fiber are wound under controlled conditions providing extra material in the head portion which is formed into the wall of the grooved portion of the head without affecting the overall sectional dimensions of the frame.

摘要： The present invention relates to a method for manufacturing at least a portion of a sports racquet frame that comprises a step a) of providing a moldable tube structure containing a first inflatable bladder and a second inflatable bladder. The first and second inflatable bladders are positioned on opposite first and second regions of the moldable tube structure. At an intermediate region, the tube structure comprises one or more cross channels, which pass through the moldable tube structure. The method according to the present invention comprises also a further step b) of inserting said tube structure inside a mold forming a mold cavity of a desired shape. Mold members are inserted into the cross channels of the tube structure, so that the outer surface of the mold member faces the inner surface of the corresponding cross channel. The mold members have position and orientation that correspond to the position and orientation, along the string bed plane, of the string port holes, which are to be formed on said frame portion. The method, according to the present invention, comprises also a step c) of pressurizing the first and second bladders, so that the tube structure conforms to the shape of the mold, and heating the mold, so that the tube structure cures. The method, according to the present invention, comprises a further step d) of removing the cured tube structure from the mold cavity and removing the mold members from the cross channels.

摘要： A composite sports racquet includes a head portion which is formed by an upper frame half and a lower frame half. Each frame half is a tubular frame section, and includes a generally flat wall. The two walls are bonded to one another to form a unitary head portion, whereby the first and second walls form internal frame ribs oriented generally parallel to the string bed plane and extending continuously around the head portion. The upper and lower frame halves are preferably pre-molded individually and thereafter glued to one another. Alternatively, one of the frame halves can be pre-molded, with the other frame half thereafter molded onto the pre-molded half Preferably, the first and second walls include a plurality of channel portions which, when the racquet halves are joined, define the string holes. Preferably, the channel portions are contoured at the outer frame surface to form curved bearing surfaces for string entry. Also, if desired, the string holes can be molded so as to extend parallel to the string ends, rather than perpendicular to the racquet frame as is generally done with drilled string holes. Preferably, the string holes have a dimension, in a direction perpendicular to the string bed plane, which is substantially greater than the diameter of standard racquet strings, so that the strings are supported only on the outer portion of the frame, thereby extending the effective string length.
摘要翻译：复合运动球拍包括由上框架半部和下框架半部形成的头部。每个框架一半是管状框架部分，并且包括大致平坦的壁。两个壁彼此粘合以形成整体头部部分，由此第一和第二壁形成大致平行于绳床平面并且围绕头部部分连续延伸的内部框架肋。上半框架和下框架半部优选地单独地预模制，然后彼此粘合。或者，框架半部中的一个可以被预成型，其后的框架一半模制在预成型的半部上优选地，第一和第二壁包括多个通道部分，当球拍半部连接时，弦孔。优选地，通道部分在外框架表面处成形，以形成用于入口的弯曲的支承表面。此外，如果需要，弦孔可以模制成平行于弦杆端部延伸，而不是垂直于球拍框架，如通常用钻孔孔孔所做的那样。优选地，弦孔在垂直于琴弦床平面的方向上具有基本上大于标准球拍琴弦的直径的尺寸，使得琴弦仅被支撑在框架的外部部分上，从而延伸有效字符串长度。

摘要： A method of moulding racquets to define stringing holes in the moulded frame. The method includes forming at least one approximately ladder-shaped member having two side pieces interconnected by rung pieces, with the side pieces substantially conforming to the curved shape of at least part of the frame of the racquet; entrapping the ladder-shaped member between two mould plates defining a mould cavity; injecting a plastic material into the mould cavity to mould the frame around the rung pieces; and forming the ladder-shaped member in two parts and separating the two parts after the frame has been moulded to remove the ladder-shaped member from the moulded frame.
