Description

에어라인이 설치된 탁구라켓과 그 제조방법{Table tennis racket with air line installed and its manufacturing method}Table tennis racket with air line installed and its manufacturing method}

본 발명은 탁구에서 반발력 향상을 높여주는 에어라인이 설치된 탁구라켓과 그 제조방법에 관한 것이다.The present invention relates to a table tennis racket provided with an air line that increases repulsion in table tennis and a method of manufacturing the same.

일반적으로, 탁구라켓은 공을 타격하는 라켓본체와 손으로 잡을 수 있는 그립부로 구성되며, 라켓 본체에는 라켓 본체를 구성하는 목판과 더불어 공의 마찰과 반발을 높이기 위한 러버가 부착된다.In general, a table tennis racket is composed of a racket body that strikes a ball and a grip part that can be held by hand, and a rubber for increasing friction and repulsion of the ball is attached to the racket body along with a wooden board constituting the racket body.

기존의 탁구라켓은 라켓본체와 러버를 별도로 제작하고, 접착제를 사용하여 부착하며, 라켓본체의 테두리를 따라 러버를 절단함으로써 완성시킨다. 라켓본체는 러버의 스폰지에 대응하는 평평한 형상으로 이루어져 있다.Existing table tennis rackets are completed by separately manufacturing the racket body and rubber, attaching them with adhesive, and cutting the rubber along the rim of the racket body. The racket body has a flat shape corresponding to the rubber sponge.

라켓본체는 하나의 목판으로 구성된 통판을 사용하거나, 하나의 두꺼운 목판에 얇은 여러 목판이나 탄소판을 사용한 합판을 사용한다. 목판의 특성에 따라 공의 라켓본체에서 타격되는 공의 반발력이나 손에 전달되는 진동에 의한 그립감이 좌우된다. 목판은 가볍고 단단한 편백나무, 호두나무, 오동나무, 은행나무 등을 사용할 수 있으며, 반발력과 그립감을 향상시키기 위해서 다른 재질을 합판하게 된다.The racket body is made of a single wooden board, or a single thick wooden board and a plywood using several thin wooden boards or carbon boards. Depending on the characteristics of the wooden board, the repulsive force of the ball hit from the racket body of the ball or the grip feeling by the vibration transmitted to the hand is influenced. The wooden board can be made of light and hard cypress, walnut, paulownia, and ginkgo, and other materials are made of plywood to improve repulsion and grip.

기존의 탁구라켓은 러버와 라켓본체가 평평한 면으로 접착제에 의해 부착됨으로써 그 사이에 공간이 있지는 않으며, 순수하게 러버와 목판의 탄발 작용에 의해 공에 대한 마찰과 반발 및 제구 성능을 제공한다. 이에 따라 라켓의 무게는 가볍게 하면서 공의 반발과 제구 성능을 향상시키는 데는 한계가 있었다.Existing table tennis rackets have no space between the rubber and the racket body as they are attached by an adhesive on a flat surface, and the rubber and the wooden board provide friction, repulsion, and ball control performance by the elastic action of the rubber and the wooden board. Accordingly, there was a limit to improving the ball's repulsion and throwing performance while making the racket lighter.

도 1 내지 도 3을 참조하면, 본 발명의 일 실시예에 따른 에어라인이 설치된 탁구라켓 제조방법은, 코어목판(100)의 양면부에 접착제를 도포하고 접착제를 경화시켜 카본층(110)을 결합하며, 코어목판(100)과 카본층(110) 사이의 접착제가 경화된 후 카본층(110)에 접착제를 도포하고 접착제를 경화시켜 표층판(120)을 결합하며, 표층판(120)에 연통된 형상을 갖는 공기홈(125)을 형성하는 것이다.1 to 3, a method of manufacturing a table tennis racket equipped with an air line according to an embodiment of the present invention comprises applying an adhesive to both surfaces of a core wooden board 100 and curing the adhesive to form a carbon layer 110. Bonding, and after the adhesive between the core wood plate 100 and the carbon layer 110 is cured, the adhesive is applied to the carbon layer 110 and the adhesive is cured to bond the surface plate 120 to the surface plate 120. It is to form an air groove 125 having a communication shape.

코어목판(100)은 중간층 목재로서, 필요한 두께만큼 가공하여 준비한다. 카본층(110)은 탄소섬유로 마련하며, 코어목판(100)의 탄성력을 더하게 된다. 이러한 코어목판(100)과 카본층(110)은 용매와 2:1로 희석된 에폭시 경화제로 접착되어 결합된다.The core wooden board 100 is an intermediate layer of wood and is prepared by processing to a required thickness. The carbon layer 110 is made of carbon fiber, and the elastic force of the core wooden board 100 is added. The core wooden board 100 and the carbon layer 110 are bonded and bonded with a solvent and an epoxy curing agent diluted 2:1.

코어목판(100) 상에 희석된 에폭시 경화제를 고르게 도포한 후, 카본층(110)을 에폭시 경화제 상에 밀착시켜 부착하고, 에폭시 경화제가 완전히 경화되어 코어목판(100)과 카본층(110)이 완전히 결합될 때까지 프레스 장치로 압박 상태를 유지시켜 준다.After evenly applying the diluted epoxy curing agent on the core wooden board 100, the carbon layer 110 is closely attached to the epoxy curing agent, and the epoxy curing agent is completely cured so that the core wooden board 100 and the carbon layer 110 are formed. Keep the pressed state with the press device until it is fully engaged.

코어목판(100)과 카본층(110)의 에폭시 경화제에 의한 결합이 충분히 이루어진 게 확인된 후에는, 동일한 에폭시 경화제를 사용하여 표층판(120)을 결합한다. 동일한 방식으로 카본층(110)과 표층판(120) 사이의 에폭시 경화제가 완전히 경화될 때까지 프레스 장치를 사용하여 카본층(110)과 표층판(120)의 압박 상태를 유지시켜 준다.After it is confirmed that the bonding between the core wood plate 100 and the carbon layer 110 by the epoxy curing agent is sufficiently made, the surface plate 120 is bonded using the same epoxy curing agent. In the same manner, a press device is used to maintain the pressed state of the carbon layer 110 and the surface plate 120 until the epoxy curing agent between the carbon layer 110 and the surface plate 120 is completely cured.

코어목판(100)의 양면부에 위치하는 표층판(120) 중 하나 이상은 1mm 두께 이상의 무늬목을 사용함이 적절하다. 표층판(120)은 코어목판(100)의 양면에 모두 무늬목을 사용할 수 있으며, 한면에 대해서만 무늬목을 사용할 수 있다.At least one of the surface layer plates 120 positioned on both sides of the core wood plate 100 is appropriate to use a veneer having a thickness of 1 mm or more. The surface layer plate 120 may use veneers on both sides of the core wood plate 100, and veneers may be used only on one side.

표층판(120)이 카본층(110)에 완전히 결합된 게 확인된 후에는, 표층판(120)의 표면을 샌드페이퍼와 같은 연마도구를 사용하여 매끄럽게 연마하며, 1차 옻칠을 수행한다.After it is confirmed that the surface plate 120 is completely bonded to the carbon layer 110, the surface of the surface plate 120 is smoothly polished using a polishing tool such as sand paper, and the first lacquer is performed.

1차 옻칠은 표층판(120) 상에 도포된 옻칠이 완전히 건조될 때까지, 8시간 이상 상온 건조를 한다. 1차 옻칠이 다 마른 게 확인된 후에는, 표층판(120)에 공기홈(125)을 가공하게 된다.The primary lacquer is dried at room temperature for 8 hours or more until the lacquer applied on the surface plate 120 is completely dried. After it is confirmed that the primary lacquer is dry, the air groove 125 is processed in the surface layer plate 120.

공기홈(125)은 레이저 커팅 및 조각기로 격자무늬 또는 라탄무늬 등을 모티브로 한 다양한 형태로 양각과 음각이 두드러지도록 골고루 파내어 형성한다. 이러한 공기홈(125)에 의해 표층판(120)에 에어라인이 형성된다. 공기홈(125)은 코어목판(100)의 양면에서 한면 또는 양면에 대해 선택적으로 수행할 수 있다.The air groove 125 is formed by digging evenly so that the embossing and the engraving are prominent in various forms having a lattice pattern or a ratan pattern as a motif by laser cutting and engraving. Air lines are formed in the surface layer plate 120 by these air grooves 125. The air groove 125 may be selectively performed on one side or both sides of both sides of the core wooden board 100.

공기홈(125)의 가공이 완료된 후에는, 2차 옻칠을 수행한다. 2차 옻칠은 1차 옻칠과 동일한 방식으로 공기홈(125)을 포함하여 고르게 옻칠을 하며, 상온에서 8시간 건조를 시킨다.After the processing of the air groove 125 is completed, a secondary lacquer is performed. The second lacquer is lacquered evenly including the air groove 125 in the same manner as the first lacquer, and dried at room temperature for 8 hours.

상기와 같이 코어목판(100), 카본층(110), 및 표층판(120)이 완전히 결합되고, 공기홈(125)이 형성되며 1, 2차 옻칠이 완성된 원판이 마련된다. 원판은 탁구라켓 형상으로 절단하여 라켓 원형을 마련하는 데 사용된다.As described above, the core wood plate 100, the carbon layer 110, and the surface plate 120 are completely combined, the air groove 125 is formed, and the primary and secondary lacquer finished original plates are provided. The disk is cut into a table tennis racket shape and used to prepare the original racket.

라켓 원형에는 손잡이(140)와 러버(150)를 부착하여, 탁구라켓을 완성시키게 된다. 러버(150)는 통상적으로 액체 글루를 라켓 원형의 표층판(120)과 러버(150)에 일정 두께로 고르게 펴고 10분 정도 건조시켜 부착하게 된다.The handle 140 and the rubber 150 are attached to the original racket to complete the table tennis racket. The rubber 150 is typically applied by spreading the liquid glue to the surface layer plate 120 and the rubber 150 in a circular racket to a predetermined thickness and drying for about 10 minutes.

한편, 액체글루 도포 시는 공기홈(125)의 음각 홈부에 일부 묻을 수도 있으나, 액체글루가 마르면 고무판인 러버(150)로 올라붙어 탄성 공기층이 형성될 공간이 충분히 확보된다. 다만, 액체글루가 너무 얇으면 부착력이 저하되고, 너무 두꺼우면 홈에 액체글루가 가득 매워져 공기층이 형성될 공간이 없어지게 되므로, 도포두께를 적절하게 조절함이 바람직하다.On the other hand, when the liquid glue is applied, some of the concave grooves of the air groove 125 may be partially buried, but when the liquid glue dries, it is adhered to the rubber 150, which is a rubber plate, thereby sufficiently securing a space in which an elastic air layer is formed. However, if the liquid glue is too thin, the adhesion is lowered, and if the liquid glue is too thick, the liquid glue is filled in the groove and there is no space for the air layer to be formed. Therefore, it is desirable to appropriately control the coating thickness.

상기와 같이 제작된 탁구라켓은 공기홈(125)으로 인한 표층판(120)과 러버(150) 사이의 에어층으로 인하여 탁구공과 러버(150)면에 전달되는 느낌이 에어라인으로 인하여 부드러우며, 스매싱과 같은 강력 타격을 할 때에, 파워와 스피드가 향상이 증가되어 성능이 배가됨으로써 기존과 차별화된 타구 성능을 나타낸다.The table tennis racket produced as described above is soft due to the air line, the feeling transmitted to the table tennis ball and the rubber 150 surface due to the air layer between the surface plate 120 and the rubber 150 due to the air groove 125, When a powerful hit such as smashing is performed, the power and speed are increased and the performance is doubled, indicating a batting performance that is differentiated from the previous one.

공기홈(125)의 에어라인은 공기층을 탁구라켓의 러버(150) 내측에 형성된 형성하는데, 탁구공이 접촉될 때 공기 탄성층을 제공함으로써 러버(150)의 표면과 탁구공 사이의 탄력적인 마찰과 타구의 제구 성능 및 향상된 반발력을 만들게 된다.The air line of the air groove 125 forms an air layer formed inside the rubber 150 of the table tennis racket. By providing an air elastic layer when the table tennis balls are in contact, elastic friction between the surface of the rubber 150 and the table tennis balls and It makes the batted ball's control performance and improved repulsion.
