摘要:
A sports racquet having a plurality of string port holes (20), i.e enlarged string holes having two inwardly facing string bearing surfaces which are spaced apart by a distance corresponding to the distance between two contiguous main strings or cross strings, and conventional string holes (18) is formed of a single tube of prepreg material. When molded, mold members (34) press opposed portions of the prepreg tube into contact with one another, and shape the opposed portions and the surrounding prepreg material (37) into a string port hole blanks (40). The portion of the pressed-together material which initially blocks the string port hole (20) is removed after molding so that the string port holes (20) extend through the frame. Alternatively, the mold members (64) cause the prepreg tube to follow a serpentine shape, thereby defining string port holes (62) which are open alternately along the top and bottom surface of the frame. A pair of cover rings (74) may be secured to the top and bottom racquet surfaces (70,72) to cover the open sides of the string port holes (62).
摘要(中):
一种运动球拍,其具有多个弦孔口(20),即具有两个向内相对的弦轴承表面的扩大的弦孔,所述两个向内的轴承表面间隔开相当于两个相邻的主弦或十字线之间的距离的距离,以及常规的弦孔 18)由单层预浸料材料形成。 当模制时,模具构件(34)将预浸料管的相对的部分彼此接触,并将相对的部分和周围的预浸料坯材料成形为串口孔坯料(40)。 在模制之后去除最初阻塞串口孔(20)的压合材料的部分,使得串口孔(20)延伸穿过框架。 或者,模具构件(64)使得预浸料管遵循蛇形形状,从而限定沿框架的顶表面和底表面交替打开的排孔口(62)。 一对盖环(74)可以固定到顶部和底部球拍表面(70,72)以覆盖琴弦孔口(62)的开口侧。
