【考案の詳細な説明】
〔産業上の利用分野〕
本考案はテニス、バトミントン用ラケツトのガ
ツト張り締め用巻き棒に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a rod for tightening the tension of tennis and badminton rackets.
従来は、第２図示のように直径30mm、長さ140
mm程度の木芯１の外周に幅2.5mm、厚さ１mm程度
の牛皮よりなるテープ２を巻き付けていた。
Conventionally, the diameter was 30 mm and the length was 140 mm as shown in the second diagram.
A tape 2 made of cowhide with a width of 2.5 mm and a thickness of about 1 mm was wrapped around the outer periphery of a wooden core 1 of about mm.
しかしこれではその外周にラケツト（図示せ
ず）に張つたガツト３の端部を巻きつけて回転さ
せガツトを張り締めするときにガツト３がその表
面を滑り、張り締めがよくできず、作業性が悪い
ばかりでなく無駄な力を要する欠点があつた。
However, with this method, when the end of the string 3, which is stretched around a racket (not shown), is wrapped around the outer periphery of the string and rotated to tighten the string, the string 3 slips on the surface of the racket, making it difficult to tighten the string properly and making the work easier. Not only was it bad, but it also had the drawback of requiring unnecessary force.
〔問題点を解決するための手段〕
第１図示のように本考案は木等よりなる芯体４
の外周面にはくびれ部５を設けると共にその外周
には天然ゴム又はウレタンゴム等のゴムの層６を
一体に成形してなるテニス、バトミントン用ラケ
ツトのガツト張り締め用巻き棒である。[Means for solving the problem] As shown in the first diagram, the present invention has a core body 4 made of wood or the like.
This is a winding rod for tightening a racket for tennis or badminton, which has a constricted part 5 on the outer circumferential surface of the racket and integrally molds a layer 6 of rubber such as natural rubber or urethane rubber on the outer periphery.
ゴムの層６は芯体４の外周面のくびれ部５，５
により芯体４と係合するので側方に脱出すること
はない。
The rubber layer 6 is formed at the constricted portions 5, 5 on the outer peripheral surface of the core body 4.
Since it engages with the core body 4, it does not escape laterally.
而してゴムの層６に第２図示のようにガツト３
を巻きつけて回転させたときにそのゴム層６の表
面の摩擦によりガツト３は滑ることがなく、効果
的に張り締めすることができ、作業性がよいと共
にガツトも傷つけることがないものである。
Then, the rubber layer 6 is covered with guts 3 as shown in the second diagram.
When the rubber layer 6 is wrapped around the string and rotated, the string 3 does not slip due to the friction on the surface of the rubber layer 6, and can be tightened effectively.It has good workability and does not damage the string. .
