CONSTITUTION: A baseball bat(8) has a knob(1) end disposed at one end of the bat adjacent to a cylindrically shaped handle portion of the bat. A weight(3) is disposed in the bat, apart from a cylindrically shaped handle portion of the bat. It is also disposed in axial alignment with the bat and can be moved through a moving duct(4) in the bat.

Description

무게 중심의 이동에 의한 연습용 야구배트{For the practice bat that form the center of gravity move of weight}Baseball bat for form by movement of center of gravity {For the practice bat that form the center of gravity move of weight}

본 고안은 연습용 야구배트에 관한 것으로서 더욱 상세하게는 배트속에 중량의 무게추의 중심이동에 의해서 하나의 배트로 무게가 다르게 느껴지는 여러개의배트가 형성되는 방법에 관한것이다.The present invention relates to a practice baseball bat, and more particularly to a method of forming a number of bats that feel different weight in one bat by moving the center of weight of the weight in the bat.

일반적으로 야구선수들이 타격시 스윙스피드를 상승시키기 위해서 일반 야구배트에 중량의 쇠붙이 링을 끼워서 허공에 스윙연습을 한다.In general, a baseball player swings in the air by putting a heavy metal ring on a regular baseball bat in order to raise the swing speed when hitting.

그 일례로서 도 1에서와 같이 일반 야구배트에 쇠붙이 링을 끼워서 스윙연습을 하고 타석에 들어서기 직전 배트무게를 최소화하고 스윙시 스피드를 급상승시키기 위해서 중량의 쇠붙이 링을 배트에 끼워서 사용을 한다.As an example, as shown in FIG. 1, an iron ring is inserted into an ordinary baseball bat to practice swinging, and a heavy metal ring is inserted into the bat to minimize the weight of the bat just before entering the plate and to rapidly increase the speed during the swing.

그러나 이와 같은 방식으로 스윙연습을 할 경우 스윙스피드를 상승시키는데 도움을 줄 수 있으나 무게조절의 필요시 쇠붙이 링을 끼웠다 뺏다 해야 하는 번거로움이 있고 쇠붙이 링과 야구배트를 따로 보관, 휴대해야 하는 불편함이 생기는 것이다.However, if you practice swinging in this way, it can help you to increase your swing speed, but if you need to adjust the weight, you need to insert and pull the metal ring. This is what happens.

본 고안은 상기와 같은 문제점을 해소하기 위해서 배트 내부에 쇠붙이 무게추를 장착하여 회전식 무게 조절장치로 무게의 중심이동을 시켜 배트무게가 다르게 느껴지도록 하는 방식으로 쇠붙이 링과 야구배트를 따로 휴대할 필요가 없으며 쇠붙이 링을 따로 끼웠다 뺏다 할 필요없이 무게조절장치를 퉁해 배트속에 장착된 쇠붙이 추의 중심이동으로 무게를 달리할 수 있는데 본 고안의 목적이 있는 것이다.In order to solve the problems described above, the present invention needs to carry a metal ring and a baseball bat separately in such a way that the weight of the bat is felt differently by moving the center of gravity with a rotary weight adjusting device inside the bat. The purpose of this invention is to be able to vary the weight by moving the center of the metal weight attached to the bat without the weight adjusting device without having to insert and separate the metal ring.

이와 같은 목적을 달성하기 위해 배트 내부에 쇠붙이 무게추를 장착하는 단계, 장착된 무게추가 이동관을 통해서 이동하는 단계, 회전 조절장치에 의해서 무게가 조절되는 단계, 전체 무게의 조절의 필요시 추가 장착과 완전 교체 장착이 용이한 단계, 쇠붙이 무게추가 안으로 내장됨에 있어 외관이 미려해진 단계로 이루어진 것에 특징이 있다.In order to achieve this purpose, there is a step of mounting an iron weight on the inside of the bat, moving the mounted weight through the moving tube, adjusting the weight by the rotation control device, additional mounting if necessary to adjust the overall weight and It is characterized by consisting of a stage that is easy to replace completely and has a beautiful appearance in that it is built into the metal weight.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

도 3의 1을 회전하면 쇠붙이 추의 받침대 2와 쇠붙이 추 3이 이동관 4를 통해 중심이동을 하게되어 무게중심이 손목쪽에 있을 때 정성적인 배트를 거꾸로 들고 스윙을 하는 경우가 되고 무게중심이 배트의 끝부분에 있게되면 정상적으로 배트를 잡고 스윙을 하는 경우와 같은 형식으로 배트전체의 무게완 상관없이 무게중심의 이동만으로 배트를 들었을 때 다른 무게의 배트가 형성되는 것이다.Rotating 1 in FIG. 3 causes the base 2 and the base 3 of the metal weight to be moved through the moving tube 4 so that the qualitative bat is swinged upside down when the center of gravity is on the wrist, and the center of gravity is the weight of the bat. If you are at the end, the bat is a different weight is formed when the bat is lifted by moving only the center of gravity, regardless of the weight of the whole bat in the same form as if you are swinging the bat normally.

도 2의 9와 10의 화살표와 눈금이 일치하면서 사용시의 무게를 알려주고 12는 쇠붙이 추의 이동을 눈으로 확인할 수 있는 투명 아크릴 판이며 11은 물과 같은 이물질의 침입을 막아주는 고무부분이 형성되어 있다.9 and 10 in Fig. 2 and the scale coincides with the weight when used, 12 is a transparent acrylic plate that can visually check the movement of the metal weight and 11 is a rubber part is formed to prevent intrusion of foreign substances such as water have.

도 3의 5와 6은 결합됨으로 쇠붙이 추가 배트 내부에서 고정되어 이동할 수 있도록 고안된 결속 부분이다.5 and 6 of Figure 3 is a binding portion designed to be fixed and moved inside the metal additional batter combined.

이로서 배트 내부에 무게추 장착과 이동을 하면서 무게를 달리 조절될 수 있는 기능이 이루어 질 수 있는 것이다.This allows the weight to be adjusted while moving and mounting the weight inside the bat.

이상에서 상술한 바와같이 본 고안은 배트 내부에 쇠붙이 무게추의 장착과 무게중심의 이동에 의해서 배트의 무게를 달리 느낄 수 있게해서 하나의 배트로 무게가 달리 느껴지는 여러개의 배트가 형성되고 사용할 수 있는 효과를 얻을 수 있으며 무게추의 이동을 조절장치의 조작에 의하여 무게 조절이 필요시 탈 부착없이내부에서 간단히 조절할 수 있으므로 무게 조절의 필요시 기존의 방식과는 달리 쇠붙이 링을 끼웠다 뺏다 할 필요가 없으므로 번거로움이 없어 편리함과 쇠붙이 링이 배트 내부에 장착되어 외관이 미려해 졌고 휴대하기가 편리해진 것이다.As described above, the present invention makes it possible to feel the weight of the bat differently by mounting the metal weight and moving the center of gravity inside the bat, so that several bats with different weights can be formed and used as one bat. The weight of the weight can be adjusted easily by the operation of the adjusting device without the need for detachment.Therefore, there is no need to insert and remove the metal ring when the weight is needed. There is no hassle and convenience and the metal ring is installed inside the bat for a beautiful appearance and easy to carry.
