본 고안은 진열장 문 개폐 장치에 관한 것으로서, 특히 문바닥 양측에 롤러를 하나는 높고 다른 것은 낮게 치우쳐서 설치하고 이 롤러가 안내되는 레일홈은 경사지게 형성하여 문을 닫을 때는 자중에 의해 자동으로 닫히도록한 진열장문 개폐장치 구성에 관한 것이다.The present invention relates to a showcase door opening and closing device, and in particular, one roller is installed on both sides of the door bottom and the other is lowered, and the rail groove in which the roller is guided is formed to be inclined so that the door is automatically closed by its own weight when the door is closed. It relates to the configuration of the display door opening and closing device.
종래 진열장은 제1, 2도에 도시한 바와 같이 문(20) 바닥 양측에 롤러(21,22)를 설치하고 이 롤러(21,22)가 끼워져서 구름 이동되는 레일홈(23)을 진열장 몸체(24)바닥 전면에 형성한 것으로서 이는 레일홈(23)이 일정한 깊이의 수평이므로 문(20)을 여닫을 때마다 일일이 손으로 문(20)을 습동시켜 열고 닫아야 되므로 매우 불편할 뿐만 아니라 제2도에서와 같이 롤러(21,22)와 평면인 레일홈(23)사이의 접촉 면적이 넓어서 회전 마찰력이 크기 때문에 최초 문(20)을 여닫을 때 "찌-익"하는 소음 발생과 롤러와 레일 마모량의 증가로 인한 진열장의 수평단축은 물론 장기간 사용시 문(20)이 헐거워지게 되는 문제점이 있었다.Conventional showcases have rollers 21 and 22 installed on both sides of the bottom of the door 20 as shown in FIGS. 1 and 2, and the rail grooves 23 into which the rollers 21 and 22 are fitted and rolled are shown on the display body. (24) It is formed on the front of the floor, because the rail groove 23 is horizontal of a certain depth, every time the door 20 is opened and closed by sliding the door 20 by hand, it is very inconvenient as well as in FIG. As the contact area between the rollers 21 and 22 and the flat rail groove 23 is large and the rotational frictional force is large, the noise generated by the opening and closing of the first door 20 and the amount of roller and rail wear increase. Due to the horizontal shortening of the showcase due to the long-term use there was a problem that the door 20 is loose.
본 고안은 이와 같은 문제점을 해결하기 위하여 진열장문은 닫힐 때 자동으로 닫히게 하여 문 개폐에 편리를 기하고 롤러와 레일홈 사이의 접촉면적을 줄여서 문 개폐시 소음 발생을 최소화하여 롤러와 레일홈의 마모량 감소를 통한 진열장 수명 연장을 도모함은 물론 장기간 사용해도 문이 헐거워질 염려가 없도록 한 진열장 문 개폐장치를 제공하는데 본 고안의 목적이 있는 것으로서, 이와 첨부된 도면을 참조하여 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention automatically closes the display door when it is closed, making it convenient for opening and closing the door, and reducing the contact area between the roller and the rail groove, thereby minimizing the occurrence of noise when opening and closing the roller and the rail groove. It is an object of the present invention to provide a showcase door opening and closing device that prevents the door from loosening even if used for a long period of time as well as to extend the showcase life through reduction, the configuration and effect of the present invention with reference to the accompanying drawings When described in detail as follows.
우선, 제3, 4도를 참조하여 본 고안의 구성을 설명하면, 진열장 몸체(1)하단 앞쪽에 형성된 V형 경사 레일홈(2)의 상단에는 수평면(2')을 형성함과 동시에 정지요홈(3)을 형성하고, 이 경사 레일홈(2)이 끼워지는 진열장 문(4)의 하단 양측에는 각각 롤러(5,6)를 몸체(1)바닥에 대하여 일측은 높게, 타측은 낮게 편심지도록 설치하여서된 것이다.First, referring to Figures 3 and 4, the configuration of the present invention will be described. At the same time, the horizontal groove 2 'is formed at the upper end of the V-shaped inclined rail groove 2 formed at the lower front of the showcase body 1, and at the same time, the stop groove (3) and rollers 5 and 6 on both sides of the lower end of the showcase door 4 into which the inclined rail groove 2 is fitted so that one side is eccentric with respect to the bottom of the body 1 and the other side is low. It was installed.
미설명 부호 7은 롤러 고정판, 8은 롤러 고정나사이다.Reference numeral 7 denotes a roller fixing plate, and 8 denotes a roller fixing screw.
본 고안의 작용효과는 제3도 및 제4a도에 도시된 바와 같이 문(4)이 닫힌 상태에서는 문(4)의 일측벽면이 몸체(1)의 일측벽면에 맞닿아 있음과 동시에 롤러(5,6)가 각각 V형 경사레일홈(2)의 최하단 쪽으로 위치하고 있게 된다.As shown in FIGS. 3 and 4a, the effect of the present invention is that the one side wall surface of the door 4 is in contact with the one wall surface of the body 1 and the roller 5 is in the state in which the door 4 is closed. And 6 are respectively located toward the lowermost end of the V-shaped inclined rail groove 2.
이러한 상태에서 문(4)를 열고자 제4a도의 점선 화살표 방향으로 문(4)을 밀면 롤러(5,6)는 경사 레일홈(2)의 최하단측으로부터 최상단으로 굴러가면서 문(4)이 열리게 된다.In this state, when the door 4 is pushed in the direction of the dotted line arrow in FIG. 4A to open the door 4, the rollers 5 and 6 roll from the bottom end side of the inclined rail groove 2 to the top end to open the door 4. do.
이와 같이 문(4)을 열다가 제4b도에 도시된 바와 같이 일측롤러(5)가 경사레일홈(2)의 최상단부에 형성된 정지요홈(3)에 빠지게 되면 이순간 롤러(5,6)의 구름 작동은 중단되어지면서 롤러(5)가 정지요홈(3)에 걸려 문(4)은 열린 상태를 유지하게 된다.In this way, when the door 4 is opened and the one side roller 5 falls into the stop groove 3 formed at the top end of the inclined rail groove 2 as shown in FIG. As the rolling operation is stopped, the roller 5 is caught by the stop groove 3 so that the door 4 remains open.
다음에 문(4)을 닫을때는 상기와 반대로 제4b도의 실선 화살표 방향으로 문(4)을 약간 이동시키면 롤러(5)가 정지요홈(3)에서 빠져나오면서 수평면(2')과 경사레일홈(2)의 경제점(ㄱ)을 지나는 순간 문(4)의 자중에 의하여 각 롤러(5,6)가 경사 레일홈(2)을 타고 최하단측으로 굴러 내리게 되어 제4a도에 도시된 바와 같이 자동으로 닫히게 되는 것이다.Next, when closing the door 4, if the door 4 is slightly moved in the direction of the solid arrow of Fig. 4B, the roller 5 will come out of the stop groove 3, and the horizontal surface 2 'and the inclined rail groove ( At the moment passing through the economic point a of 2), the rollers 5 and 6 roll down to the lowermost side by the inclined rail groove 2 due to the weight of the door 4, and as shown in FIG. It will be closed.
이와 같이 문(4)을 개폐할 때 경사레일홈(2)은 V형홈 형상으로 이 속에 끼워진 롤러(5,6)와의 접촉이 선접촉이 되어 마찰력이 적어지게 되므로 문(4)개폐시 적은 힘으로 원활히 개폐 할 수 있고 닫힐 때 자중에 의한 자동 닫힘이 정확해 지게 된다.As such, when the door 4 is opened and closed, the inclined rail groove 2 has a V-shaped groove, and the contact with the rollers 5 and 6 fitted therein becomes a line contact so that the frictional force is reduced. It can be opened and closed smoothly and the automatic closing by self weight will be accurate when it is closed.
또한 마찰력 감소로 인한 롤러(5,6)와 경사 레일홈(2)간의 마모량이 줄게 되어 문(4)의 개폐 빈도수가 많아도 헐거워 지게될 염려가 없게 되고 따라서 문(4)의 수평연장이 되는 것이다.In addition, the amount of wear between the rollers 5 and 6 and the inclined rail groove 2 due to the reduced frictional force decreases, so that there is no fear of loosening even if the frequency of opening and closing the door 4 is large, and thus the horizontal extension of the door 4 is performed. .
이와 같이 본 고안에 의하면 진열장 문이 자동으로 닫히게 되어 문 개폐시 편리를 도모할 수 있고 문 개폐시 발생하게 되는 소음을 최소화할 수 있게 된 것이다.As such, according to the present invention, the showcase door is automatically closed, thereby facilitating convenient opening and closing of the door and minimizing noise generated when opening or closing the door.
