본 발명은 냉장고등의 가전제품의 도어 좌우 개폐장치의 현지와 도어 손잡이의 연관된 작동으로 도어를 좌우 마음대로 열고 닫을 수 있게 한 것이다.The present invention enables the door to be opened and closed freely from side to side by the associated operation of the door handle and the door of the left and right door opening and closing device of a home appliance such as a refrigerator.

종래의 냉장고나 가전제품에서 도어 개폐를 좌, 우로 마음대로 열고 닫을 수 있게 하기 위하여 도어의 좌, 우측 상, 하에 힌지 구멍을 형성하고 힌지를 좌우공용으로 설치 가능하도록 함으로서 좌측 혹은 우측으로 변경하여 냉장고의 문을 개폐하도록 하였으므로 인하여 소비자들이 힌지의 고장이 났을 때 이를 교체하기 위하여 따로 공구를 사용하므로 그 제품외관에 부주의로 흠집을 내는 등 많은 어려움이 뒤따랐으며 도어 손잡이는 단순히 도어에 고정되어 아무런 작동이 없었다.In order to allow the door to be opened and closed at any time in a conventional refrigerator or home appliance, a hinge hole is formed on the left, right, top and bottom of the door, and the hinge can be installed for right and left to change the left or right side of the refrigerator. Since the door is opened and closed, consumers use a separate tool to replace the hinge when it breaks down, which leads to many difficulties such as inadvertently scratching the exterior of the product. The door handle is simply fixed to the door and no operation is performed. There was no.

또한 일측에만 손잡이 및 힌지를 설치하여 좁은 공간에 설치하기가 어렵고 넓은 공간을 차지하는 불편이 있었다.In addition, by installing the handle and the hinge only on one side, it was difficult to install in a narrow space and occupy a large space.

그러나 본 발명은 냉장고의 전면 좌우측 상부 및 하부에 부라켓트를 설치하고 상하도어 손잡이 사이에 부라켓트를 설치함으로써 힌지봉을 수직으로 지지하고 이 상하 힌지봉이 손잡이의 레버 작동간을 당기고 약간 눌렀을 때 연동되어 회전하는 주회전간 상하 우, 좌 암나사에 끼워져 상하로 승강되어서 좌측 손잡이로 도어를 열으면 우측 손잡이의 상, 하 및 중간 도어사이 부라켓트로 지지힌지되므로 도어가 열리고 닫히게 작동되고 또한 우측 손잡이를 잡아 당기고 놓아서 도어를 열고 닫으면 그 지지 힌지는 좌측손잡이 작동처럼 좌측 힌지봉으로 열고 닫을 수 있게 한 것이다.However, the present invention supports the hinge rods vertically by installing the brackets between the upper and lower left and right sides of the refrigerator and installing the bracket between the upper and lower door handles, and the upper and lower hinge rods pull the lever operation of the handle and press it slightly. When the door is opened with the left handle, the door is opened and closed because the hinge is supported by the left and right, left and right female screws, and the upper and lower left and right handles are opened by the left handle. When the door is opened and closed by pulling and releasing it, the supporting hinge is opened and closed with the left hinge rod as the left-handed operation.

본 발명은 이와 같이 종래의 힌지를 없애고 손잡이를 개량한 것으로 도어의 힌지없이 상하 및 도어사이 부라켓트를 설치하고 손잡이의 레버작동간의 연동작용으로 상하로 힌지봉을 승강시키어서 도어를 오른쪽, 왼쪽에서 마음대로 쉽게 열고 닫을 수가 있으므로 좁은 공간에 유용하게 설치할 수 있는 것으로서 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention removes the conventional hinge and thus improved the handle to install a bracket between the top and bottom and the door without the hinge of the door and to raise and lower the hinge rod up and down by the interlocking action between the lever operation of the handle right, left Since it can be easily opened and closed at will as it can be usefully installed in a narrow space as described in detail by the accompanying drawings as follows.

냉장고 전면 좌우측 상부에는 부라켓트(1)를 체결하는데, 부라켓트 수직부에 구멍(1a)은 스크류를 사용하여 냉장고 본체에 고정하기 위한 구멍이며, 수평부구멍(1b)은 좌, 우측 힌지봉이 삽입되는 구멍이며, 이 부라켓트(1)는 냉장고 본체에 고정되는 부분과 힌지봉(6)을 삽입하는 구멍(1b)이 있는 부분이 수직으로 굽힘되어져 있는데 냉장고의 하부에는 상부와 정반대방향으로 굽힘하여 사용한다.The rackets 1 are fastened to the upper left and right sides of the refrigerator, and the holes 1a in the vertical parts of the refrigerator are holes for fixing to the refrigerator main body using screws, and the horizontal holes 1b are hinged left and right.

Hole, the upper horizontal hole 2b is a hole for supporting the hinge rod of the upper door of the refrigerator, the lower horizontal hole 2c is a hole for supporting the hinge rod 5 of the lower door of the refrigerator, The portion supported on the front of the refrigerator and the portion having the hinge holes 2b and 2c are formed perpendicular to each other, and are necessarily fastened between the doors of the refrigerator.

랙(3)은 냉장고의 손잡이(8)에 선회핀이 끼워진 지점(8a)과 랙(3) 일끝단부의 선회핀이 끼워진 회전지점(3a)에다 레버간(9)을 연결하고, 또 냉장고 손잡이 일측하부 안쪽으로 스프링 걸고리 돌기(8b)를 고장하여 랙 일끝단부의 돌기(3b)와 연결되게 스프링(11)을 탄설하고 랙(3) 일끝단부는 안내지지부(14)를 설치하여 레버간(9)의 당김과 누르는 작동을 원활히하고, 이 레버간(9)과 연동되게 하고 주회전간(7)의 회전운동으로 변환시킨다.The rack (3) connects the lever (9) to the point (8a) where the turning pin is fitted to the handle (8) of the refrigerator and the turning point (3a) at which the turning pin is fitted at one end of the rack (3). The spring hook protrusion 8b is broken into one side lower portion and the spring 11 is piled up so as to be connected to the protrusion 3b at one end of the rack, and one end of the rack 3 is provided with a guide support 14 to install the guide portion 14 between the levers. The pulling and pressing operation of) is smoothed, and the lever is interlocked with the levers 9 and converted into the rotational movement of the main rotations 7.

이때 주회전간(7)의 상부는 암오른나사(7b)하부는 암왼나사(7c)를 각각 상하에 형성시켜 상부 힌지봉(5) 및 하부힌지봉(6)나사로 연결 작동되게 하여 주회전간(7)의 기어(7a) 회전운동에 의하여 상하직선운동을 하게 하여 상하 안내지지부(12)(13)내홈에서 상하힌지봉(5)(6)의 돌기편(5d)(6d)이 승강되어 결국 부라켓트 구멍(2c)과 (1b)에 상하 힌지봉(5)(6)이 끼워져 냉장고도어 손잡이(8)로 좌우 어느쪽에서든지 열고 닫을 수 있도록 형성하였다.At this time, the upper part of the main rotation section (7), the lower part of the female right screw (7b) to form the upper and lower female screws (7c), respectively, to be connected to the upper hinge rod (5) and the lower hinge rod (6) to operate the main rotation interval (7). (7a) by the rotational movement of the gear (7a) to move up and down in the inner groove of the upper and lower guide support (12) (13), the protrusion pieces (5d) (6d) of the upper and lower hinge rods (5) and (6) are eventually raised The upper and lower hinge rods 5 and 6 are inserted into the racket holes 2c and 1b, and the refrigerator door handles 8 are formed to be opened and closed on either side.

이와 같이 구성된 본 발명은 냉장고 좌우측에 부착되어 있는 손잡이(8)의 레버간(9)에 힘을 가하지 않은 상태는 냉장고 좌우 양측이 부라켓트(1)(2)의 구멍(1b)(2b)(2c)속에 힌지봉(5)(6)이 끼워지게 되므로 냉장고의 도어는 열리지 않는다.According to the present invention configured as described above, in the state where no force is applied to the levers 9 of the handle 8 attached to the left and right sides of the refrigerator, the left and right sides of the refrigerator are holes 1b and 2b of the racket 1 and 2. Since the hinge rods 5 and 6 are fitted in the 2c, the door of the refrigerator is not opened.

그러나 냉장고의 문을 열고자 할 경우에는 첨부도면 제5도와 같이 좌우 어느쪽의 손잡이(8)의 레버간(9)을 누르면 레버간(9)과 연결되어 있는 랙(3)이 ＂가＂방향으로 직선운동을 하게 되고 따라서 랙(3)과 맞물려 있는 주회전간(7)의 외주면기어(7a)가 회전운동하게 되며 주회전간(7)의 회전운동으로 주회전간(7) 내측에 형성되어 있는 상부의 오른나사(7b) 및 하부의 왼나사(7c)가 회전하므로 이 오른나사에 나삽되어 승강운동하는 상부 힌지봉(5)은 ＂나＂방향으로 내려오게 되고 왼나사에 나삽되어 승강운동하는 하부 힌지봉(6)은 ＂다＂방향으로 상승하게 되어 냉장고의 문은 쉽게 열수 있다.However, in order to open the door of the refrigerator, as shown in FIG. 5, when the levers 9 of the handles 8 on the left and right sides are pressed, the rack 3 connected to the levers 9 moves in the right direction. And the outer circumferential gear 7a of the main rotation section 7 engaged with the rack 3 rotates, and the upper part formed inside the main rotation section 7 by the rotational movement of the main rotation section 7. Since the right screw (7b) and the lower left screw (7c) of the rotation is rotated, the upper hinge rod (5), which is screwed into the right screw and moves up and down, comes down in the direction of ＂, (6) rises in the ＂direction so that the door of the refrigerator can be opened easily.

이때 레버간(9)은 스프링(11)을 압축한다.At this time, the lever (9) compresses the spring (11).

그리고 냉장고 도어를 닫고자할 경우에는 냉장고 손잡이의 누름레버간(9)을 첨부도면 제4도와 같이 놓으면 손잡이(8)와 누름레버간(9)사이에 설치된 압축스프링(11)에 의하여 레버간(9)이 원위치로 돌아가고 이때 누름레버간(9)과 연동된 랙(3)과 주회전간(7)의 내부상하에 형성된 암나사인 오른나사(7b) 및 외나사(7c)에 각기 끼워 승강되는 힌지봉(5)(6)의 나사(5a)(6a)작동이 원위치로 됨으로 냉장고의 도어는 열기전의 상태 즉 힌지봉(5)(6)이 부라켓트(1)(2)의 각구멍(1b)(2b)(2c)에 끼워져 닫혀 힌지되는 것이다.When the refrigerator door is to be closed, the lever lever 9 of the refrigerator handle is placed as shown in FIG. 4 and the lever spring (11) is installed between the handle 8 and the lever lever 9. 9) is returned to its original position, and the hinge which is lifted up and down respectively by the right and left threads 7b and the external threads 7c, which are formed on the upper and lower sides of the rack 3 and the main rotation shaft 7, interlocked with the push lever stem 9, respectively. Since the operation of the screws 5a and 6a of the rods 5 and 6 is returned to their original positions, the door of the refrigerator is in a state before opening, that is, the hinge rods 5 and 6 are each holes of the rackets 1 and 2, respectively. 1b) (2b) (2c) is fitted and closed and hinged.

이와 같이 냉장고등 가전제품 사용시 손잡이의 당김과 누름에 따라서 도어를 좌측 혹은 우측 마음대로 개폐할 수 있고 따로히 잠금장치등을 요하지 않아 사용시 편리한 특징이 있는 것이다.Thus, when using a home appliance, such as a refrigerator, the door can be opened or closed freely according to the pull and push of the handle, and there is no need for a locking device.

따라서 종래와 같이 도어에 손잡이마다 각기 힌지를 하지 않고 좌측이나 우측 손잡이를 잡고서 레버간을 작동시킴으로 도어가 열고 닫을 수가 있어 어린이가 냉장고를 자주열고 닫기가 어려워 냉장고의 냉장효과를 증진하고 따라서 냉장고 도어를 좌우에서 열고 닫을 수 있어 좁은 공간에서 설치될 수 있으므로 냉장고의 설치면적에 구애됨이 없이 설치할 수 있는 특징이 있다.Therefore, the door can be opened and closed by operating the lever by holding the left or right handle without hinges to the door handles as in the prior art, so it is difficult for children to open and close the refrigerator frequently, thereby improving the refrigerating effect of the refrigerator and thus opening the refrigerator door. Since it can be opened and closed from left and right, it can be installed in a narrow space, so it can be installed without regard to the installation area of the refrigerator.

그리고 위에서 설명한 것은 본 발명의 도어손잡이를 수직으로 냉장고도어 좌우양측에 설치한 것으로 그 작동 및 작용효과인 경우이나 또 다른 실시예로 본 발명 도어 손잡이를 냉장고도어 상부, 하부 및 상하도어 사이에 각기 부라켓트(1)를 설치하고 손잡이(8)를 수평으로 착설하여 손잡이의 레버간(9)을 당기고 누름에 따라 랙(3) 및 주회전간(7)이 연동되어서 각 힌지봉(5)(6)이 좌우 왕복운동함으로 도어를 필요에 따라서 상하로 열고 닫을 수도 있는 것이다.In addition, the above-described door handle of the present invention is installed vertically on both sides of the refrigerator door, and in the case of its operation and effect or in another embodiment, the door handle of the present invention is provided between the upper, lower and upper and lower doors of the refrigerator door. Install the racket (1), install the handle (8) horizontally, and pull the lever lever (9) of the handle and push the rack (3) and the main rotation interval (7) in accordance with each hinge rod (5) (6 ), The door can be opened and closed up and down as needed.

이와 같이 손잡이를 힌지없이 단순히 손잡이의 레버의 당김과 누름에 의하여 도어 어느 위치에도 설치하여 좁은 공간에서도 마음대로 냉장고를 설치하여서 도어를 열고 닫을수가 있게 한 것이 본 발명의 유익한 점이다.As described above, it is an advantage of the present invention that the refrigerator is installed at any position of the door by simply pulling and pressing the lever of the handle so that the door can be opened and closed at will in a narrow space.
