ｔ発明した。The present inventors have determined that 1% of the competitive characteristics of a competitive racket is the speed at which the pole or feather bounces off the racket, which is the part of the handle of the racket adjacent to the throat of the racket (that is, the area between the head and handle of the racket). The inventors unexpectedly discovered that the above could be achieved by providing a plurality of parallel grooves in the racket. . The present inventors have surprisingly discovered that the power (as defined above) of the racket is improved by providing the plurality of parallel grooves in the handle of the racket.
従って１本発明は、ガツトを張つｔヘッド部と。Therefore, one aspect of the present invention is to provide a T-head portion that is firm.
のど部と柄部とからなり、のど部に丁ぐ隣り合う柄部の
外周に複数の平行な溝が延在する競技用ラケットを提供
する。To provide a competition racket, which is composed of a throat part and a handle part, and has a plurality of parallel grooves extending on the outer periphery of the adjacent handle parts located at the throat part.
溝はラケットの柄部の外周に半分より短い寸法にわｔっ
て延在するのが好ましく、まｔ溝は柄部の中央横断面と
鋭角をなｆように形成でると都合がよい。Preferably, the groove extends over less than half the circumference of the racquet handle, and advantageously the groove is formed at an acute angle with the central cross-section of the handle.
上記複数の溝が柄部の長さの約３０％にわたって延在す
るのに十分なだけの溝を設けるのが好ましい。Preferably, there are sufficient grooves such that the plurality of grooves extend over about 30% of the length of the handle.
溝は１例えば矩形、三角形あるいは弧状のような任意の
都合のよい断面形状をもつことが可能で。The grooves can have any convenient cross-sectional shape, such as rectangular, triangular or arcuate.
ラケットの製造中現場成形によりあるいは製造後のラケ
ットに機械加工するととにより得られる。It may be obtained by in-situ molding during manufacture of the racket or by machining the racket after manufacture.

業者に公知である。Two squash racquets were made in the same manner using material Y of iM-, one racquet containing a plurality of parallel grooves according to the invention, and the other racquet constituting a control standard. It is known to those skilled in the art how to construct each racquet by molding it in different molds so that the racket does not have grooves or grooves.

The assembly containing the plastic tube is then removed from the mandrel and placed into a mold that defines the shape of a squash racket, the mold is closed and heated, causing the plastic tube to expand and create molding pressure.

The speed of the ball was measured using a speed measuring device.The results of this test showed that a racket with grooves was able to return the ball faster than a racket without grooves. This shows that the racket with grooves has a larger power7 in terms of "power" defined by the formula power = (rebound speed) x 100 as described above. There is.
