백화점, 대형 쇼핑몰, 식품가게 등에서는 일부 식품을 오랫동안 냉장 보관하면서 판매하기 위해 냉각장치가 구비된 쇼케이스의 내부에 식품을 저장하고, 고객들이 보관중인 식품을 잘 볼 수 있게 하기 위해, 쇼케이스의 측벽과 도어는 유리 또는 복층유리로 제작되고 있다. In department stores, large shopping malls, food stores, etc., food is stored inside a showcase equipped with a cooling device in order to keep some food refrigerated for a long time and sell it. The door is made of glass or double-glazed glass.
이와 같이 유리도어로 제작된 쇼케이스에서 고객들이 필요한 식품을 선택하고 나서 도어를 열어 놓은 채 자리를 뜨는 경우가 많이 있어 한편으로는, 냉기가 외부로 유출되어 식품 저장공간의 온도가 상승하여 부패가 쉬워지고, 유출된 냉기를 보상하기 위해 과도한 전력이 소모되는 문제점이 있다. Like this, in a showcase made of glass doors, there are many cases where customers select the food they need and then leave with the door open. However, there is a problem in that excessive power is consumed to compensate for the leaked cold air.
이러한 문제 등을 해소하기 위해 쇼케이스나 냉장고를 포함한 여러 분야의 도어를 자동으로 닫히게 하는 연구가 다방면으로 이루어지고 있다. In order to solve these problems, various studies have been conducted to automatically close doors in various fields including showcases and refrigerators.
대한민국 등록특허 제10-0781601호에서는 냉장고 본체의 일측 하부에 고정힌지를 돌출되게 형성하고, 상기 고겅힌지에 곡선형 가이드홈과 걸림홈을 형성하고, 가이드홈과 걸림홈에 삽입되어 이동할 수 있도록 하는 가동편과 고정힌지와 상기 가동편을 연결하여 탄성력을 제공하는 스프링 및 도어에 설치되어 가동편에 걸리거나 이탈되는 걸림돌기를 포함하여 구성된 냉장고 도어의 자동닫힘 장치가 개발된 바 있다. 상기 기술은 두꺼운 냉장고 도어에 설치되어 도어를 열때는 스프링이 늘어나며 장력이 발생하고, 도어를 놓으면 스프링의 장력이 풀리면서 도어를 자동으로 닫히게 할 수는 있으나, 얇은 도어를 사용하는 쇼케이스와 같은 구조에서는 미관상 고정힌지를 외측으로 많이 돌출되게 설치할 수 없어 쇼케이스와 유사한 장치에서는 적용하기 어렵다는 문제점이 있다. Korean Patent Registration No. 10-0781601 discloses that a fixed hinge is formed to protrude from the lower part of one side of the refrigerator body, a curved guide groove and a locking groove are formed on the hinge, and the guide groove and the locking groove are inserted into the locking groove to be movable. An automatic closing device for a refrigerator door has been developed, including a spring connecting a movable piece, a fixed hinge, and the movable piece to provide elastic force, and a locking protrusion that is installed on the door and is caught on or released from the movable piece. The above technology is installed on a thick refrigerator door, so that when the door is opened, the spring is stretched and tension is generated, and when the door is released, the tension of the spring is released and the door can be automatically closed. However, in a structure such as a showcase using a thin door, There is a problem in that it is difficult to apply the fixed hinge to a device similar to a showcase because it cannot be installed to protrude much outward in terms of aesthetics.
대한민국 공개특허 제10-2020-0133163호에서는 하부 문틀의 하부에 장척의 볼트형 힌지축이 설치되고, 힌지축에 감긴 스프링이 결합되며, 볼트형 힌지축의 상부에 도어가 결합된 것으로, 도어를 열면 일정한 압력으로 감겨있는 스프링에 압력이 추가되고, 열린 문을 놓으면 스프링이 풀리면서 도어가 닫히도록 구성된 자동 도어가 개시되어 있다. 상기 기술은 문틀의 하부에 여유공간이 없는 쇼케이스에서는 힌지축을 설치하기가 어렵고, 압축된 스프링의 힘으로 도어가 닫히면서 충격을 주지만 선반 등에 가해지는 충격을 완화하는 수단이 없다는 문제점이 있다. In Korean Patent Publication No. 10-2020-0133163, a long bolt-type hinge shaft is installed at the bottom of the lower door frame, a spring wound around the hinge shaft is coupled, and a door is coupled to the top of the bolt-type hinge shaft. When the door is opened, Disclosed is an automatic door configured such that pressure is added to a spring wound at a constant pressure and the door is closed as the spring is released when the open door is released. The above technique has a problem in that it is difficult to install a hinge axis in a showcase where there is no free space at the bottom of the door frame, and there is no means to alleviate the impact applied to the shelf or the like although the door closes with the force of the compressed spring and gives an impact.
상기와 같은 문제점을 개선하기 위해 본 고안은 쇼케이스와 같이 얇은 도어와 같이 여유공간이 없는 좁은 곳에서도 설치되어 도어가 자동으로 닫히도록 하고, 도어가 90°도로 열렸을 때는 정지상태를 이루며, 도어를 닫을 때 충격을 완화할 수 있는 여닫이문의 자동 닫힘 구조를 제공하고자 한다. In order to improve the above problems, the present invention is installed even in a narrow place where there is no free space, such as a thin door such as a showcase, so that the door automatically closes, and when the door is opened at 90 °, it stops and closes the door. It is intended to provide an automatic closing structure of a casement door that can mitigate the impact when the door is closed.
