Description

휴대용 테니스공 보관함 {Portable tennis ball container}Portable tennis ball container [0001]

본 발명은 테니스 용품에 관한 것으로, 더욱 상세하게는 저온환경에서도 테니스공의 반발력을 일정하게 유지시킬 수 있도록 구성된 "휴대용 테니스공 보관함” 에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to tennis equipment, and more particularly, to a portable tennis ball storage unit configured to maintain a repulsive force of a tennis ball constant in a low temperature environment.

일반적으로 겨울철 실외에서 테니스를 즐기는 동호인들은 0℃ 이하의 저온에서 테니스를 칠 경우 일정시간 이후 공의 온도가 내려감에 따라 공 내부의 공기압이 저하되어 공의 반발력이 상온(10℃~20℃)에서의 반발력에 비해 매우 낮아져 공의 튐(bouncing)에 문제가 발생하여 운동시 불편함을 느낀다.Generally, when a tennis player is playing tennis at a temperature of 0 ° C or less in winter, the air pressure inside the ball decreases as the ball temperature is lowered after a certain period of time, and the repulsive force of the ball is lowered from room temperature (10 ° C to 20 ° C) (Bouncing) of the ball is very low as compared with the repulsive force of the ball.

테니스 동호인들은 이러한 문제의 해결책으로는 겨울철 영하의 기온으로 냉각된 테니스공을 클럽하우스에 있는 난로 위나 라지에이터에 공을 올려 놓고 일정시간 후 온도가 올라간 공을 다시 사용하거나, 반발력이 저하된 공을 그대로 치는 경우가 대부분이다. 전자의 경우 온도조절의 어려움으로 공의 튐(bouncing)이 일정하지 않고 다시 공의 온도가 낮아졌을 때 동일한 방법을 반복적으로 사용함으로 인해 운동의 흐름이 끊기는 번거로움의 문제가 있고, 후자의 경우 상온에 비해 공의 튐(bouncing)이 현저히 떨어져 정상적인 테니스 플레이가 어려운 문제점이 있다.As a solution to this problem, tennis lovers can use a cold tennis ball in the winter to cool the tennis ball on the stove or in the radiator in the clubhouse, use the heated ball again after a certain period of time, Most of them are hit. In the former case, the bouncing of the ball is not constant due to the difficulty in controlling the temperature. When the temperature of the ball is lowered again, there is a problem in that the flow of motion is interrupted due to repeated use of the same method. In the latter case, The bouncing of the ball is significantly lower than that of the ball, which makes it difficult to play normal tennis.

이와 유사한 문제의 해결책으로 고안된 타사례로는 US 8,616,270 B2 (Ralph Samuel Granchelli, Jr.) 2013.12.31.에서 테니스공의 온도를 일정하게 유지하는 장치의 개념에 대한 설명이 있다. 그러나 상기 특허의 내용은 다소 다량의 테니스공을 여러 장치(히터, 냉각기, 휀 외)가 장착된 중대형의 용기에서 히팅하는 개념으로, 중대형 장치 형태와 전원공급 방식의 특성상 이동성이 제한적이고 실제 활용에 어려움이 예상된다.Other examples devised as a solution to this problem include US 8,616,270 B2 (Ralph Samuel Granchelli, Jr.) on December 31, 2013, which describes the concept of a device that keeps the temperature of a tennis ball constant. However, the above patent discloses a concept of heating a relatively large amount of tennis balls in a middle- or large-sized container equipped with various devices (heaters, coolers, fans, etc.), and the mobility is limited due to the characteristics of the medium- Difficulty is expected.

또는 시판되고 있는 겨울철용 테니스공을 사용하는 경우도 있는데 이것은 일반 테니스공에 비해 다소 고가로 수요가 한정적이고 쉽게 구매가 어려운 단점이 있어서 그리 많이 이용되지 않고 있다.Or a commercially available tennis ball for winter season is used, which is somewhat expensive compared with a general tennis ball, and the demand is limited and it is difficult to purchase easily, so it is not used much.

이에 본 발명은 겨울철 테니스를 즐기는 사용자들이 낮은 기온으로 인해 반발력이 저하된 테니스공을 휴대용 테니스공 보관함을 이용하여 장소에 상관없이 빠른 시간에 상온의 공상태로 복원시켜 정상적인 테니스 플레이가 가능하도록 한 것이다.Accordingly, the present invention enables normal tennis players to enjoy a tennis ball having a low repulsive force due to low temperature in winter, by restoring the tennis ball to a ball at room temperature in a short time regardless of a place using a portable tennis ball storage .

본 발명은 0℃ 이하의 낮은 기온으로인해 반발력이 저하된 테니스 공을 장소에 상관없이 빠른시간에 히팅이 가능하도록 하기위해 휴대가 가능한 소량의 테니스공 히팅 공간을 구성하였고 전원공급 장치를 충전식 전원방식으로 하였으며, 히터의 열이 테니스 공에 빠르게 전달될 수 있도록 하기위해 공과 가열매체의 간격을 최대한 근접 시킨 형태로 고안된 장치이다.The present invention has a small amount of tennis ball heating space that can be carried so that the tennis ball having a low repulsive force due to low temperature below 0 ° C can be heated quickly regardless of the place, And it is a device designed in such a way that the distance between the ball and the heating medium is as close as possible in order to allow the heat of the heater to be transmitted to the tennis ball quickly.

겨울철 0℃ 이하의 낮은 기온에서 반발력이 저하된 테니스공을 빠른 시간에 상온의 상태로 복원시켜 장소에 상관없이 겨울철 테니스 이용자들에게 안정적인 테니스 플레이가 가능하도록 할 수 있다.In winter, tennis balls with low repulsive force at low temperatures of less than 0 ℃ can be restored to normal temperature in a short period of time, so that tennis players can enjoy stable tennis in winter regardless of the place.

도면 2는 제2실시 예에 따른 휴대용 테니스공 보관함의 개념도1 is a conceptual view of a portable tennis ball storage box according to the first embodiment;
2 is a conceptual view of a portable tennis ball storage box according to the second embodiment.

이하 첨부 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 휴대용 테니스볼 보관함은 휴대가 가능하도록 하기 위해 2개의 테니스공을 넣을 수 있는 용기 형태의 개념으로 뚜껑부(100), 본체부(200), 제어 및 전원공급부(300)로 구성된다.The portable tennis ball storage box includes a lid part 100, a main body part 200, and a control and power supply part 300 in the form of a container type in which two tennis balls can be inserted so as to be portable.

뚜껑부(100)는 히팅시 발생하는 열이 외부로 나가지 않도록 차단을 하기 위한 것이고,The lid part 100 is for blocking the heat generated during heating so as not to go out,

본체부(200)는 내부 테니스볼 보관용기(230)와 가열수단(220), 보온재(210)로 구성된다.The main body 200 includes an internal tennis ball storage container 230, a heating means 220, and a heat insulating material 210.

내부 보관용기(230)는 테니스공을 가열하기위한 공간으로 테니스공과 가열수단(220)과의 간격을 최대한 밀착시켜 열전달 효율을 좋게 할 수 있도록 하였다.The inner storage container 230 is a space for heating the tennis ball, so that the distance between the tennis ball and the heating means 220 is minimized to maximize the heat transfer efficiency.

가열수단(220)은 온도가 낮아진 테니스공에 열을 전달하는 발열체로서 전력 소모량과 효율성을 고려하여 여러 형태(코일형 또는 면상 발열체)의 적용이 가능하다. 그러나 가열수단(220)은 전술된 형태로 한정되는 것은 아니다.The heating means 220 is a heating element that transmits heat to a tennis ball having a reduced temperature, and can take various forms (coil type or area heating element) in consideration of power consumption and efficiency. However, the heating means 220 is not limited to the above-described form.

또한 히팅시 열이 내부의 테니스공 방향으로만 전달되게 하기위해 외함과 가열수단(220) 사이에 보온재(210)를 배치하였으며 가열수단(220)의 형태에 따라 생략이 가능하다.Also, a heat insulating material 210 is disposed between the enclosure and the heating means 220 to allow the heat to be transmitted only toward the inner tennis ball during heating, and can be omitted depending on the type of the heating means 220.

제어 및 전원공급부(300)는 제어장치와 충전장치를 배치하는 공간으로 자동온도제어장치(310)는 히팅 시간 및 온도조절이 가능할 수 있도록 하는 히팅센서를 포함하였고, 전원공급장치(320)는 충전식을 적용하여 장소에 상관없이 휴대 사용이 가능하게 하였으며 방전시 보조 밧데리로 재충전이 가능하도록 하였다.The control and power supply unit 300 is a space for disposing the control unit and the charging unit. The automatic temperature control unit 310 includes a heating sensor for controlling the heating time and the temperature. The power supply unit 320 includes a rechargeable battery , Which makes it possible to use the battery regardless of the location, and enables recharging with auxiliary battery when discharging.

본 장치의 사용법은 매우 간단하다. 0℃ 이하로 냉각된 테니스공을 휴대용 테니스공 보관함에 넣고 뚜껑을 닫은 후 히팅버튼을 누르면 가열이 진행되고 일정시간 후 적정온도에서 히팅이 중단되어 테니스공이 과도하게 가열되지 않도록 한다. 히팅이 완료되면 공을 꺼내어 사용하면 되는 방식이다. The use of this device is very simple. Put the tennis ball cooled to below 0 ℃ into the portable tennis ball storage box and press the heating button after the lid is closed. Heating will be continued and after a certain time, the heating will be stopped at the proper temperature to prevent the tennis ball from being heated excessively. When the heating is completed, the ball is taken out and used.
