본체(10)의 하부에는 본체(10)를 설치면(100)과 이격 상태로 지지함과 동시에 수평조절 등을 위해 본체(10)의 높이를 조절할 수 있는 복수의 레그조립체(40)가 설치된다.The lower part of the main body 10 is provided with a plurality of leg assembly 40 for supporting the main body 10 in a spaced apart state and at the same time to adjust the height of the main body 10 for horizontal adjustment and the like. .

도 2 내지 도 4는 본 발명에 따른 세탁기 레그조립체의 제1실시 예를 나타낸 것이다. 도 2에 도시한 바와 같이, 제1실시 예의 레그조립체(40)는 본체(10)의 하부에 체결되는 수나사부(42) 및 수나사부(42)의 하부에 마련된 지지부(43)를 갖춘 레그(41)와, 레그(41)의 수나사부(42)에 체결되는 조임부재(50)를 포함한다. 2 to 4 illustrate a first embodiment of a washing machine leg assembly according to the present invention. As shown in FIG. 2, the leg assembly 40 of the first embodiment includes a leg having a male screw portion 42 fastened to the lower portion of the main body 10 and a support portion 43 provided at the lower portion of the male screw portion 42. 41 and a fastening member 50 fastened to the male screw portion 42 of the leg 41.

레그(41)의 수나사부(42)는 도 2에 도시한 바와 같이, 본체(10)의 바닥판(18)에 형성된 관통공(19)을 통하여 본체(10)의 내부로 진입하며, 바닥판(18)의 내측에 고정된 너트(20)에 체결된다. 따라서 이러한 레그(41)는 수나사부(42)를 조이거나 풀어 본체(10)의 하부로 노출되는 부분의 높이를 조절함으로써 본체(10)의 높이를 조절할 수 있다.As shown in FIG. 2, the male screw portion 42 of the leg 41 enters the inside of the main body 10 through a through hole 19 formed in the bottom plate 18 of the main body 10, and the bottom plate. It is fastened to the nut 20 fixed inside of 18. Therefore, the leg 41 can adjust the height of the main body 10 by adjusting the height of the portion exposed to the lower portion of the main body 10 by tightening or loosening the male screw portion 42.

조임부재(50)는 도 2와 도 4에 도시한 바와 같이, 둘레 쪽에 요철부(51)가 마련된 원판형태로 마련되며, 레그(41)의 수나사부(42)에 체결될 수 있도록 그 중심부에 암나사부(52)를 구비한다. 이러한 조임부재(50)는 도 3에 도시한 바와 같이, 그 상면(53)이 본체(10)의 하면과 접하도록 조여 줌으로써 레그(41)의 높이를 조절한 상태에서 레그(41)가 풀리지 않도록 결속할 수 있게 한 것이다. 외면의 요철부(51)는 조임부재(50)를 조이거나 풀 때 미끄러짐을 방지함으로써 조임부재(50)를 손쉽게 조이거나 풀 수 있도록 한다. 2 and 4, the tightening member 50 is provided in the form of a disc provided with an uneven portion 51 on the circumferential side, and the center of the tightening member 50 to be fastened to the male screw portion 42 of the leg 41 A female screw portion 52 is provided. As shown in FIG. 3, the fastening member 50 is tightened so that the upper surface 53 is in contact with the lower surface of the main body 10 so that the leg 41 is not released in a state where the height of the leg 41 is adjusted. It is to be united. The uneven portion 51 of the outer surface prevents slipping when tightening or loosening the tightening member 50 so that the tightening member 50 can be easily tightened or loosened.

또 조임부재(50)는 수지재의 사출성형을 통하여 제조한다. 이는 조임부재(50)를 수지재질로 제조함으로써 외부의 충격이 가해지는 경우에도 조임부재(50)가 파손되지 않도록 한 것이다. 즉 종래의 금속재질로 된 조임부재에 비하여 내충격성이 커지도록 한 것이다. 또 이처럼 조임부재(50)를 수지재질로 만들 경우에는 조임부재(50)를 조일 때 조임부재(50)의 상부가 본체(10)의 하면 형상에 대응하여 약간 변형되면서 본체(50)의 하면과 밀착될 수 있기 때문에 조임부재(50)의 풀림을 방지하는 효과도 높일 수 있다.In addition, the fastening member 50 is manufactured by injection molding of a resin material. This is because the fastening member 50 is made of a resin material so that the fastening member 50 is not damaged even when an external impact is applied. That is, the impact resistance is increased as compared with the conventional tightening member made of metal. In addition, when the tightening member 50 is made of a resin material as described above, when the tightening member 50 is tightened, the upper part of the tightening member 50 is slightly deformed to correspond to the lower surface shape of the main body 10 and the lower surface of the main body 50. Since it can be in close contact can also increase the effect of preventing the loosening of the fastening member (50).

또 조임부재(50)는 상면(53)이 평면으로 이루어진다. 이는 도 3에 도시한 바와 같이, 조임부재(50)의 상면(53)이 본체(10)의 하면과 밀착되도록 조임부재(50)를 조일 때 조임부재(50) 상면(53)과 본체(10) 하면 사이의 접촉면적이 커져 마찰력이 커지도록 함으로써 본체(10)의 진동이 생기는 경우에도 조임부재(50)의 풀림이 방지되도록 한 것이다. In addition, the fastening member 50 is the upper surface 53 is made of a flat. 3, the upper surface 53 and the main body 10 of the tightening member 50 when the tightening member 50 is tightened to closely contact the lower surface of the main body 10 as shown in FIG. 3. In this case, the contact area between the lower surfaces is increased to increase the frictional force so that the loosening of the tightening member 50 is prevented even when the main body 10 is vibrated.

조임부재(50)의 하면에는 암나사부(52) 주위에 환형돌출부(54)가 마련된다. The lower surface of the tightening member 50 is provided with an annular projection 54 around the female screw portion 52.

이는 조임부재(50)가 과도하게 풀려 레그(41)의 지지부(43) 쪽으로 이동할 경우 환형돌출부(54)가 지지부(43)의 육각머리부(43a)와 먼저 접하도록 함으로써 조임부재(50)가 과도하게 풀리는 경우에도 조임부재(50)의 암나사부(52)가 파손되는 문제를 방지할 수 있도록 한 것이다. 이러한 구성은 조임부재(50)가 레그(41)의 육각머리부(43a, 금속재질)보다 연질인 수지재질인 점을 감안한 것으로, 조임부재(50)의 암나사부(52)가 육각머리부(43a) 또는 수나사부(42) 하측의 나사산이 형성되지 않는 부분과 접하는 것을 방지하여 암나사부(52)의 파손을 방지할 수 있도록 한 것이다.This is because when the tightening member 50 is excessively loosened and moved toward the support 43 of the leg 41, the annular protrusion 54 first contacts the hexagonal head 43a of the support 43 so that the tightening member 50 is contacted. Even if excessively loosened to prevent the problem that the female screw 52 of the tightening member 50 is broken. This configuration takes into account that the tightening member 50 is made of a resin material that is softer than the hexagonal head 43a (metal material) of the leg 41, and the female threaded portion 52 of the tightening member 50 is a hexagonal head ( 43a) or to prevent the female screw portion 52 from being damaged by contact with a portion where the screw thread under the male screw portion 42 is not formed.

도 5와 도 6은 본 발명에 따른 세탁기 레그조립체의 제2실시 예를 나타낸 것이다. 도 5에 도시한 바와 같이, 제2실시 예의 레그조립체(140)는 제1실시 예와 마 찬가지로, 수나사부(142) 및 지지부(143)를 갖춘 레그(141)와, 레그(141)의 수나사부(142)에 체결되는 조임부재(150)를 구비한다. 여기서 제2실시 예는 조임부재(150)가 수지재질로 이루어지고, 제1실시 예와 달리 그 상면(153)이 오목면으로 된 것이다. 즉 조임부재(150)는 상면(153)의 중심 쪽 높이가 둘레 쪽보다 낮게 형성된 것이다. 5 and 6 show a second embodiment of a washing machine leg assembly according to the present invention. As shown in FIG. 5, the leg assembly 140 of the second embodiment, like the first embodiment, has a leg 141 having a male thread part 142 and a support part 143 and the number of legs 141. The fastening member 150 is fastened to the threaded portion 142. Here, in the second embodiment, the tightening member 150 is made of a resin material, and unlike the first embodiment, the upper surface 153 is a concave surface. That is, the fastening member 150 is formed in the height of the center side of the upper surface 153 is lower than the circumferential side.

이러한 구성은 도 6에 도시한 바와 같이, 조임부재(150)를 조일 경우 조임부재(150)의 중심부분이 약간 상승되도록 변형되면서 조임부재(150)의 상면(153)이 본체(10)의 바닥판(18) 하면에 밀착되도록 한 것이다. 이는 조임부재(150)를 조일 때 조임부재(150)의 변형에 따른 잔류응력에 의해 조임부재(150)의 둘레 쪽이 강한 압력으로 본체(10) 하면을 가압하는 형태가 되도록 함으로써 본체(10) 하면과 조임부재(150) 상면 사이의 마찰력이 커지도록 하고, 이를 통해 조임부재(150)의 풀림이 방지될 수 있도록 한 것이다. 그 밖의 구성은 위의 제1실시 예와 동일하므로 설명을 생략하기로 한다.As shown in FIG. 6, the upper surface 153 of the tightening member 150 is the bottom of the body 10 while being deformed so that the central portion of the tightening member 150 is slightly raised when the tightening member 150 is tightened. The plate 18 is to be in close contact with the lower surface. This is the main body 10 by pressing the lower surface of the main body 10 with a strong pressure due to the residual stress caused by deformation of the fastening member 150 when tightening the fastening member 150 to the main body 10 The frictional force between the lower surface and the upper surface of the tightening member 150 is increased, and thus the loosening of the tightening member 150 is prevented. Other configurations are the same as those of the first embodiment, so description thereof will be omitted.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 세탁기는 레그조립체의 조임부재가 수지재질로 이루어지기 때문에 외부의 충격 등으로부터 조임부재의 파손을 방지할 수 있는 효과가 있다. As described above in detail, the washing machine according to the present invention has an effect of preventing breakage of the tightening member from external impacts, because the tightening member of the leg assembly is made of a resin material.

또 본 발명은 조임부재의 상면이 평면으로 이루어져 본체 하면과의 접촉면적이 확되될 수 있기 때문에 조임부재 상면과 본체 하면 사이의 마찰력을 증대시킬 수 있다. 따라서 세탁기의 진동이 생기는 경우에도 조임부재의 풀림을 방지할 수 있는 효과가 있다.In addition, the present invention can increase the friction between the upper surface of the tightening member and the lower surface of the main body because the upper surface of the tightening member can be made flat, the contact area with the lower surface of the main body can be secured. Therefore, even when vibration of the washing machine has an effect of preventing loosening of the fastening member.
