And the door 15 is provided with a transparent glass to enable the perspective of the goods displayed in the showcase.

상기 전,후방 안내레일(12)(13)의 단면은 철(凸)형으로 형성되어 안내레일(12)(13)의 상면에 이물질이 끼지 않도록 구성된다.The cross section of the front and rear guide rails 12 and 13 is formed in an iron shape so that foreign substances are not caught on the upper surfaces of the guide rails 12 and 13.

상기 전,후방 롤러부(12)(13)는 각각 도어(15)의 하단부에 취부되는 동일한 길이를 가지는 브래키트(21)(31)와, 상기 안내레일(12)(13)의 상면이 끼워져 안내되는 홈(23)(33)이 형성되고 상기 브래키트(21)(31)에 굴대설치되어 있는 롤러(22)(32)로 구성된다. 상기 롤러(22)(32)의 홈(23)(33)과 상기 철형의 안내레일(12)(13)의 구성에 의하면 롤러(22)(32)와 안내레일(12)(13)의 접촉면이 최소화된다.The front and rear roller parts 12 and 13 are respectively fitted with brackets 21 and 31 having the same length that are mounted to the lower end of the door 15, and the upper surfaces of the guide rails 12 and 13 are fitted. Guide grooves (23) (33) are formed and consists of rollers (22) (32) that are mandrel mounted on the brackets (21) (31). According to the structure of the grooves 23 and 33 of the rollers 22 and 32 and the guide rails 12 and 13 of the iron type, the contact surfaces of the rollers 22 and 32 and the guide rails 12 and 13 are formed. This is minimized.

한편, 상기 후방안내레일(13)의 우측 단부에는 도어(15)의 열림상태를 유지하는 걸림부(14)가 형성되어 도어(15)를 완전히 우측으로 열게 되면 후방롤러부(30)의 롤러(32)가 상기 걸림부(14)에 걸려 도어(15)가 열린상태를 유지하게 된다.On the other hand, at the right end of the rear guide rail 13 is formed a locking portion 14 to maintain the open state of the door 15, when the door 15 is completely opened to the right, the roller of the rear roller part 30 32 is caught by the catch 14 to keep the door 15 open.

상기와 같이 구성된 본 발명에 의한 쇼케이스의 도어자동닫힘장치의 작용효과를 설명하면 다음과 같다.Referring to the effect of the automatic door closing device of the showcase according to the present invention configured as described above are as follows.

쇼케이스 내부에 전시되어 있는 제품을 꺼내기 위해 도어(15)를 열게 되면 도어(15)의 롤러(22)(32)가 안내레일(12)(13)에 의해 각각 안내된다. 즉 안내레일(12)(13)의 경사를 거슬러 올라가면서 도어(15)가 이동되어 도어(15)가 열리게 된다. 이 상태에서 제품을 꺼낸 후, 도어(15)에서 손을 떼게 되면, 도어(15) 자체의 하중과 안내레일(12)(13)의 경사에 의해 롤러(22)(32)가 안내레일(12)(13)을 따라 이동되면서 도어(15)가 닫히게 된다.When the door 15 is opened to take out the products displayed in the showcase, the rollers 22 and 32 of the door 15 are guided by the guide rails 12 and 13, respectively. That is, the door 15 is moved while going up the inclination of the guide rails 12 and 13 to open the door 15. After the product is removed in this state and the hand is released from the door 15, the rollers 22 and 32 are guided by the load of the door 15 itself and the inclination of the guide rails 12 and 13. The door 15 is closed while moving along the 13.

이때, 상기 롤러(22)(32)가 굴대설치되어 있는 브래키트(21)(31)는 롤러부(20)(30)가 동일한 경사를 가지는 상기 전,후방 안내레일(12)(13)에 의해 안내되도록 되므로 그 길이가 서로 동일하여 종래와 같이 일측 브래키트가 길어 변형이 발생하는 등의 문제가 발생되지 않으며, 안내레일(12)(13)의 형상이 철형으로 형성되어 레일(12)(13)상에 이물질이 잔류하지 않게 됨과 동시에 롤러(22)(32)와의 접촉면적이 최소로 되어 롤러(22)(32)가 레일(12)(13)상을 이동하는데 마찰이 최소로 줄어들게 된다.At this time, the brackets 21 and 31 on which the rollers 22 and 32 are mandrel are provided on the front and rear guide rails 12 and 13, in which the roller parts 20 and 30 have the same inclination. Since the length is equal to each other so that one side of the bracket is long as in the prior art does not cause a problem such as deformation occurs, the shape of the guide rails 12, 13 is formed in an iron shape rail (12) ( At the same time, foreign matter does not remain on the surface 13 and the contact area with the rollers 22 and 32 is minimized so that the rollers 22 and 32 move on the rails 12 and 13 to minimize the friction. .

한편, 안내레일(12)(13)의 경사를 종래에 비해 크게 할 수 있으므로, 도어닫힘상태에서 롤러(22)(32)가 있는 되는 안내레일(12)(13)의 좌측의 높이를, 제4도의 (b)에 도시된 바와 같이, 최대한 낮게 설계할 수 있어 도어닫힘상태에서의 냉기유출을 최소화할 수 있게 된다.On the other hand, since the inclination of the guide rails 12 and 13 can be made larger than in the prior art, the height of the left side of the guide rails 12 and 13 with the rollers 22 and 32 in the door closed state is determined. As shown in (b) of Figure 4, it can be designed as low as possible to minimize the cold air leakage in the door closed state.

한편, 도어(15)의 열림상태를 장시간 유지할 필요가 있을 경우에는 후방롤러부(30)의 롤러(32)가 후방안내레일(13)의 걸림부(14)에 걸려질 때까지 도어(15)를 열어주면 롤러(32)가 걸림부(14)에 걸려 도어(15)의 닫힘이 방지된다.On the other hand, when it is necessary to keep the open state of the door 15 for a long time, the door 15 until the roller 32 of the rear roller part 30 is caught by the locking part 14 of the rear guide rail 13. Opening the roller 32 is caught by the locking portion 14 to prevent the door 15 from being closed.

위에서 상세히 설명한 바와 같은 본 발명에 의한 쇼케이스의 도어자동닫힘장치에 의하면 전,후방롤러부의 브래키트 길이가 동일하게 형성되어 있어 종래와 같이 상대적으로 길이가 긴 브래키트가 변형되는 문제가 발생되지 않고, 안내레일의 경사를 종래의 것에 비해 크게 할 수 있어 도어의 닫힘이 원활하고, 도어닫힘 상태에서의 레일높이가 제4도의 (b)에서 볼 수 있는 것 같아 낮아 냉기유출이 적어지며, 레일의 형상이 철형으로 형성되어 레일상면에 이물질이 끼지 않고 롤러와의 접촉면적이 최소화되어 롤러회전이 원할하게 되는 효과가 있다.According to the automatic door closing device of the showcase according to the present invention as described in detail above, the front and rear rollers have the same length of the brackets, and thus the problem of deforming the relatively long brackets as in the prior art does not occur. Since the inclination of the guide rail can be increased compared to the conventional one, the door is smoothly closed, and the height of the rail in the closed state is not as low as that shown in FIG. It is formed in this iron shape and the foreign matter is not caught on the upper surface of the rail and the contact area with the roller is minimized, so that the roller rotation is smooth.
