본 고안은 베드민턴이나 테니스 라켓볼 그리고 스카시에 사용하는 라켓에 관한 것으로 상세하게는 라켓의 공간부에 격벽을 형성하여 라켓강도를 보강하도록 하여 라켓의 휨을 방지하도록 하여서 된 것이다.The present invention relates to a racket for use in badminton, tennis racket ball and scsi, in detail to form a partition wall in the racket to reinforce the racket strength to prevent the racket bending.
일반적으로 라켓에 가해지는 하중은 공을 타구할때 발생하는 측면하중과, 거트장력과 충격하중에 의해 정면하중과 단면하중이 발생한다.In general, the load on the racket is generated by the lateral and cross loads due to the side loads and the gut and impact loads.
따라서. 라켓은 가벼우면서도 측면하중과 정면하중 그리고 단면하중에 견디는 강도를 갖추어야 하였으며 이러한강도에 견디는 라켓을 제공하기 위하여 지금까지는 신소재 개발에 전념하였다.therefore. The racket had to be lightweight, yet have strength to withstand side loads, frontal loads and sectional loads. Until now, it has been devoted to developing new materials to provide rackets that withstand these strengths.
즉 신소재의 개발 순서를 나열하면 목재, 대나무, 알미늄,유리섬유, 탄소섬유,세라믹,보론위스커 그리고 최근에는 캐블러라는 순서로 신소재가 개발되어 라켓강도와 품질향상에 많은 개발이 이루어 졌으나 신소재개발에 따른 재료의 원가가 상승되는 결함이 있는 것이다.In other words, the development order of new materials is listed in order of wood, bamboo, aluminum, glass fiber, carbon fiber, ceramic, boron whisker, and recently, Kevlar, and new materials have been developed in order to improve racquet strength and quality. There is a defect that the cost of the material increases.
이러한 재료의 원가 상승를 막기 위하여 최근에는 라켓틀체의 단면체적을 크게하여 강도를 보강하도록 하고 있으나 이와 같은 경우 두께를 20mm에서 30mm이상까지 크게 함으로서 공을 타구할때 발생하는 측면강도는 보강되었으나 라켓의 한정된 무게에서 체적이 크게 됨으로서 정면강도와 단면강도가 약하여지는 결함이 발생하는 것이다In order to prevent the cost increase of these materials, in recent years, the cross-sectional area of the racket frame has been increased to reinforce the strength. However, in this case, the thickness of the racket is increased from 20 mm to 30 mm or more, thereby increasing the lateral strength generated when the ball is hit. The larger the volume at, the weaker the frontal strength and cross-sectional strength are.
즉 본고안은 측면두께를 종래의 라켓과 동일한 두께로 구성하되 그내부에1개 내지 2개 의 격벽을 형성시켜 라켓의 한정된 무개에서 측면강도 및 정면강도 그리고 단면강도를 높일 수 있도록 한 것이다.In other words, this proposal is to configure the side thickness to the same thickness as the conventional racket, but to form one or two partitions therein so as to increase the side strength and front strength and cross-sectional strength in the limited flat of the racket.
이하 본 고안을 첨부된 도면의 따라 상세히 설명하면, 손잡이 (1)과 틀체 (2) 그리고 망(3)으로 이루어지는 통상의 라겟(8)에 있어서 망(3)을 고정하는 틀체 (2)의 내부 중공부 (4)에는 1개 내지 2개의 격벽(5) 또는 (6) (6')을 형성하여서 된 것으로 상기와 같이 구성된 본 고안은 첨부된 도면 제2도 및 제3도(가)에 도시된 바와 같이 중앙에 형성된 격벽(5)을 관통하는 줄 삽입공(7)을 통해 통상의 방법과 같이 틀체 (2)에 망(3)을 구성할때 격벽(5)에 의하여 단면강도와 측면강도 그리고 정면강도가 보강되었기 때문에 줄을 팽팽히 고정 시킬수 있는 것이며 첨부된 도면 제3도 (나)에 도시된 바와 같이 격벽(6)(6')을 2중으로 구성함으로서 더욱더 강도를 높일 수 있는 것이다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, in which a frame 2 for fixing a mesh 3 in a conventional racket 8 composed of a handle 1, a frame 2 and a mesh 3 is provided. The present invention constituted by forming one to two partitions 5 or 6 and 6 'in the hollow part 4 is illustrated in the attached drawings 2 and 3 (a). As described above, when the mesh 3 is formed in the frame 2 through the string insertion hole 7 penetrating the partition 5 formed in the center, the cross section strength and the side strength are obtained by the partition wall 5. And since the front strength is reinforced, it is possible to fix the string tightly, as shown in (b) of FIG. 3 (b) of the accompanying drawings.
상기와 같이 중공부 (4)에 격벽(5) 또는 (6)(6')을 형성함으로 틀체는 변형이 적게 되고 고급 신소재를 사용하지 않고 저가의 소재를 사용하여도 충분히 강도를 유지 시킬수 있기 때문에 제품의 저렴화를 가져올 수가 있는 것이다.By forming the partitions 5 or 6 or 6 'in the hollow part 4 as described above, the framework is less deformed and the strength can be sufficiently maintained even if a low-cost material is used without using high-grade new materials. It can bring down the cost of the product.
