본 고안은 서랍식 냉장고용 롤러 조립체에 관한 것으로, 특히 조립공정수를 줄이고, 베어링의 마모를 최대로 억제하며, 제품의 수명을 연장시킬 수 있는 서랍식 냉장고용 롤러 조립체에 관한 것이다.The present invention relates to a roller assembly for a drawer-type refrigerator, and more particularly, to a roller assembly for a drawer-type refrigerator, which can reduce the number of assembly processes, minimize the wear of a bearing, and extend the life of the product.

일반적으로 서랍식 냉장고에서는 제4도에 도시한 바와 같이 서랍의 개폐를 원활하게 하기 위하여 냉장고 본체의 양 내측면에 롤러 조립체(R)를 설치하고, 서랍의 양측에 레일(6)을 설치하여 이 레일(6)이 상기 롤러 조립체(R)에 안내되도록 함으로써 서랍이 원활하게 개폐되도록 하고 있다.Generally, in the drawer type refrigerator, as shown in FIG. 4, in order to facilitate opening and closing of the drawer, roller assemblies R are installed on both inner surfaces of the refrigerator main body, and rails 6 are provided on both sides of the drawer. By allowing the 6 to be guided to the roller assembly R, the drawer is opened and closed smoothly.

종래의 롤러 조립체(R)는 제1도에 도시한 바와 같이 냉장고 본체의 양 내측면에 고정되는 샤프트(1)의 외주면에 그 내주면이 밀착되도록 끼워지는 내륜체(4)와, 이 내륜체(4)의 외경보다 큰 내경을 가지는 외륜체(3)와, 이들 내륜체(4)의 외주면과 외륜체(3)의 내주면사이에 삽입되어 내륜체(4)와 외륜체(3)가 원활하게 회전되도록 하는 다수개의 볼(5) 및, 상기 외륜체(3)의 외주측에 결합되는 롤러(2)로 구성된다.As shown in FIG. 1, the conventional roller assembly R includes an inner ring body 4 which is fitted such that its inner circumferential surface is in close contact with the outer circumferential surface of the shaft 1 fixed to both inner surfaces of the refrigerator main body as shown in FIG. The inner ring body 3 and the outer ring body 3 are smoothly inserted between the outer ring body 3 having an inner diameter larger than the outer diameter of 4) and the outer circumferential surface of these inner ring bodies 4 and the inner circumferential surface of the outer ring body 3. It consists of a plurality of balls (5) to be rotated, and a roller (2) coupled to the outer peripheral side of the outer ring body (3).

이와 같이 구성된 종래의 서랍식 냉장고용 롤러 조립체(R)는 샤프트(1)에 고정 결합되는 내륜체(4)와 롤러(2)에 고정 결합되는 외륜체(3)사이에 볼(5)이 삽입되어 있어 내륜체(4)와 외륜체(3)의 상대 회전이 원활하게 이루어짐과 아울러 이에 따라 롤러(2)가 샤프트(1)에 대하여 원활하게 회전할 수 있게 되므로 서랍을 개폐할 때 레일(6)이 롤러 조립체(R)에 의하여 안내되어 서랍을 원활하게 개폐할 수 있게 되는 이점이 있다.The roller assembly (R) for the conventional drawer type refrigerator constructed as described above has a ball (5) inserted between the inner ring body (4) fixedly coupled to the shaft (1) and the outer ring body (3) fixedly coupled to the roller (2). The relative rotation of the inner ring body 4 and the outer ring body 3 is smoothly performed, and accordingly, the roller 2 can be smoothly rotated with respect to the shaft 1 so that the rail 6 can be opened and closed when the drawer is opened and closed. Guided by this roller assembly (R) has the advantage that can be opened and closed smoothly.

그러나 내륜체(4)와 외륜체(3) 및 볼(5)이 금속 재질로 형성되어 있으므로 사용시 볼(5)의 마모가 심하게 발생되어 베어링의 동작이 원활하지 못하여 냉동실 및 야채실의 개폐동작이 부드럽지 못하게 되는 문제점이 있었다. 또한 외륜체(3)를 롤러(2)에 삽입하는 공정이 복잡하고 까다로워서 가격이 상승되는 문제점이 있었다.However, since the inner ring body 4, the outer ring body 3 and the ball 5 are formed of a metal material, the wear of the ball 5 is severely used during use, so that the operation of the bearing is not smooth and the opening and closing operation of the freezer compartment and the vegetable compartment is smooth. There was a problem that could not be. In addition, the process of inserting the outer ring body 3 into the roller 2 has a problem that the price is increased because of the complexity and difficulty.

따라서 본 고안은 상기한 문제점을 해소하기 위한 것으로, 그 목적은 베어링의 마모를 최대로 억제하여 제품의 수명을 연장시킬 수 있도록 하고, 부품수 감소로 조립 생산성을 향상하고 원가를 절감할 수 있도록 한 서랍식 냉장고용 롤러 조립체를 제공하는데 있다.Therefore, the present invention is to solve the above problems, the purpose is to restrain the wear of the bearing to the maximum to extend the life of the product, to reduce the number of parts to improve the assembly productivity and reduce the cost A roller assembly for a drawer refrigerator is provided.

위와 같은 목적을 달성하기 위하여 본 고안은 냉장고 본체의 양 내측면에 고정되는 샤프트에 고정되는 내륜체와, 내주면에 볼삽입홈이 원주방향으로 형성된 플라스틱 재질의 롤러와, 상기 내륜체의 외주면과 롤러의 볼삽입홈사이에 볼을 삽입하여서 구성됨을 특징으로 하는 서랍식 냉장고용 롤러 조립체를 제공한다.In order to achieve the above object, the present invention provides an inner ring body fixed to a shaft fixed to both inner surfaces of a refrigerator main body, a roller of a plastic material formed with a ball insertion groove in a circumferential direction on an inner circumferential surface, and an outer circumferential surface and a roller of the inner ring body. Provides a roller assembly for a drawer type refrigerator characterized in that the ball is inserted between the insertion groove of the ball.

위와 같이 구성된 본 고안의 실시례를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings an embodiment of the present invention configured as described above are as follows.

본 고안에 의한 서랍식 냉장고용 롤러 조립체는 제2도 내지 제3도에 나타낸 바와 같이 냉장고 본체의 양 내측면에 고정되는 샤프트(1)에 내륜체(4)를 고정시키고, 롤러(2)에 볼삽입홈(2a)을 형성하여 상기 내륜체(4)와 롤러(2)의 볼삽입홈(2a)사이에 볼(5)을 삽입하여 구성된다.In the roller assembly for a drawer type refrigerator according to the present invention, as shown in FIGS. 2 to 3, the inner ring body 4 is fixed to the shaft 1 fixed to both inner surfaces of the refrigerator main body, and the ball is fixed to the roller 2. The insertion groove 2a is formed to insert the ball 5 between the inner ring body 4 and the ball insertion groove 2a of the roller 2.

이러한 본 고안은 샤프트(1)에 고정되는 내륜체(4)와 롤러(2)가 볼삽입홈(2a)에 삽입된 볼(5)들에 의하여 상대적인 회전이 원활한 상태로 직접 결합되는 것이므로 냉동실 서랍 또는 야채실 서랍 등의 레일(6)이 상기 롤러(2)의 외주면에 안내될 때 롤러(2)의 회전이 원활하게 이루어짐과 아울러 롤러(2)와 레일(6)사이의 마찰이 감소되어 서랍이 원활하게 개폐되는 것이다.The present invention is a freezer compartment drawer because the inner ring body (4) and the roller (2) fixed to the shaft (1) is directly coupled in a relatively smooth state by the balls (5) inserted into the ball insertion groove (2a) Alternatively, when the rail 6 of the vegetable compartment drawer or the like is guided to the outer circumferential surface of the roller 2, the rotation of the roller 2 is smoothly performed, and friction between the roller 2 and the rail 6 is reduced, thereby reducing the drawer. It will open and close smoothly.

한편, 본 고안에서는 별도의 외륜체를 사용하지 않고 상기 롤러(2)를 플라스틱 재질로 형성하는 과정에서 볼삽입홈(2a)을 형성하고, 이 롤러(2)의 볼삽입홈(2a)과 상기 내륜체(4)사이에 볼(5)을 삽입하는 것에 의하여 간편하게 제조할 수 있게 될 뿐만 아니라 부품수를 줄일 수 있으며, 볼(5)의 마모를 최대로 억제시킬 수 있게 된다.In the present invention, a ball insertion groove 2a is formed in the process of forming the roller 2 with a plastic material without using a separate outer ring body, and the ball insertion groove 2a of the roller 2 and the By inserting the ball 5 between the inner ring bodies 4, not only can be manufactured easily, but also the number of parts can be reduced, and the wear of the ball 5 can be suppressed to the maximum.

따라서 본 고안은 간단한 구조로 부품수를 줄여 조립 생산성 향상과 원가절감을 기할 수 있음과 아울러 제품의 수명을 연장시킬 수 있는 이점이 있다.Therefore, the present invention has the advantage of improving the assembly productivity and cost reduction by reducing the number of parts with a simple structure and extending the life of the product.
