Patent number: 5516100Abstract: In production of a tennis or badminton racket frame in a mould under application of heat with pressure, an impervious tube is inserted into an FRP tubular material, a pair of such tubular materials are arranged in a spaced juxtaposition in the mould, a string guide strip having transverse, through string holes is inserted between the pair off tubular materials with it string holes being directed normal to the juxtaposition, and internal pressure is applied into the tubular materials during application of heat with pressure. Formation of the string holes is carried out concurrently with mould shaping of the racket frame, thereby greatly simplifying the process with reduction in cost. Absence of the conventional string hole drilling results in smooth opening of the string holes in the end product, thereby avoiding undesirable string breakage during setting under tension to the head of the racket frame.Type: GrantFiled: December 22, 1994Date of Patent: May 14, 1996Assignee: Yamaha CorporationInventor: Yoshihiro Natsume

Patent number: 5290031Abstract: In construction of an attachment-type string protector for racket frames including a base strap and a number of sleeves aligned on the base strap, the base strap is made of a relatively rigid synthetic resin, and a number of tubular vibration absorbers made of a soft synthetic material are inserted into respective sleeves almost over the entire length of the latter in full surface contact with strings. Full surface contact of the vibration absorbers with the strings over an increased length assures high degree of impact damping at shooting balls.Type: GrantFiled: December 28, 1992Date of Patent: March 1, 1994Assignee: Yamaha CorporationInventor: Yoshihiro Natsume
