정구용 공Tennis ball

제1도는 본 고안의 전체 사시도.1 is an overall perspective view of the present invention.

제2도는 본 고안의 일부를 절개한 전체 사시도.Figure 2 is an overall perspective view of a part of the present invention incision.

제3도는 제1도의 A-A선 단면도이다.3 is a cross-sectional view taken along the line A-A of FIG.

본 고안은 폴리우레탄을 발표시켜서 그 표면에 방수층을 형성하면서 기모층을 도포하여 공전체의 탄성을 유연성 있게 하면서도 부드러운 촉감을 주어 부주의로 인한 인체에 접촉이 되거나 유리창등에 충격이 가해진다 하여도 유리창이 깨지거나 상처를 주는 결점이 없도록 한 완구용 정구공에 관한 것이다.The present invention releases polyurethane and forms a waterproof layer on its surface, applying a brushed layer to make the elasticity of the whole sheet flexible while giving a soft touch to the human body due to carelessness or impact on the glass window. The present invention relates to a toy tennis ball that is free from cracks and scars.

종래의 정구용 공은 중심부에 공기를 주입된 것이 있으나 탄성과 부드러운 촉감이 약하여 부주의로 인한 인체 접촉이나 유리등에 접촉된 경우 본의 아닌 불상사가 발생되는 결점이 있었다. 그러나 본 고안에서는 우레탄의 탄성과 표면에 방수층을 도층시켜 공이 물에 잠수되어도 표면에만 물이 묻고 공내부에는 침수되지 않을 뿐만 아니라 기모층이 있어 촉감이 양호한 것이어서 어린이들도 장소에 구애됨이 없이 놀 수 있도록한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Conventional tennis ball is injected into the center of the air, but the elasticity and soft touch is weak, the inadvertent accident occurs when the human body contact or glass contact due to carelessness. However, in the present invention, the urethane's elasticity and the waterproofing layer are coated on the surface, so that even if the ball is submerged in water, the water will only be buried in the surface and will not be submerged inside the ball. When described in detail by the accompanying drawings to be as follows.

완구용 정구공(1)을 형성함에 있어서 폴리우레탄이나 특수 합성고무(2)제로 한 공(1) 표면에 방수층(3)을 형성시킨 표면에 기모층(4)이 되도록 도포시킨 것이다.In forming the toy ball 1 for a toy, it is apply | coated so that it may become the brushed layer 4 on the surface in which the waterproof layer 3 was formed in the surface of the ball 1 made of polyurethane or special synthetic rubber (2).

이와같은 구조의 작용 효과를 설명하면 다음과 같다.The effect of such a structure is demonstrated as follows.

폴리우레탄이나 특수합성고무(2)제로 한 공(1)에 미세공(2′)이 형성되어 탄성 작용이 촉진되며 공(1) 표면에 방수층(3)이 있어 습기의 침입이 방지되어 물이 공(1) 표면에 닿아도 다른 공으로 교체함이 없이 계속 사용할 수 있으며 방수층(3) 표면의 기모층(4)은 촉감을 부드럽게 하여 공(1)이 라켓에 닿는 촉감 역시 부드러워 라켓을 움직이는데 부담을 덜어주며 폴리우레탄이 가지는 유연성에 의하여 인체나 유리등에 강하게 접촉되어도 종래와 같이 통증이나 유리가 파손되는 율이 격감되게 하고 유연성에 따른 내구성에 의하여 수명을 연장시킬 수 있도록 한 효과를 가지므로 정구용 공으로서는 매우 실용적가치가 큰 것이다.Fine holes (2 ') are formed in the ball (1) made of polyurethane or special synthetic rubber (2) to promote elastic action, and there is a waterproof layer (3) on the surface of the ball (1) to prevent moisture from entering. Even if it touches the surface of the ball (1), it can be used continuously without replacing it with another ball, and the brushed layer (4) on the surface of the waterproof layer (3) softens the touch so that the touch of the ball (1) touches the racket is also soft. As a ball for tennis, it has the effect of reducing the pain or damage rate of glass as in the prior art and prolonging its life due to its flexibility. It is very practical.

Claims (1)

도면에 표시된 바와같이 폴리우레탄(2)으로된 공(1)의 표면에 방수층(3)과 기모층(4)을 형성하여 유연성과 내구성이 양호 토록한 정구용공.As shown in the drawing, the water resistant layer 3 and the brushed layer 4 are formed on the surface of the ball 1 made of polyurethane 2 so that the flexibility and durability are good.
