Description

가구용 받침 로울러Furniture Support Rollers

제1도는 본 고안의 분해 사시도.1 is an exploded perspective view of the present invention.

제2도는 본 고안의 종단면도.2 is a longitudinal sectional view of the present invention.

본 고안은 대형가방이나 탁자등의 저면에 체착하는 자유회전형 받침로울러의 구조를 개량하여 종래와 같이 금속제 베어링볼이 없이도 로울러의 회전방향이 자유자재로 되게한 합성수지의 받침로울러에 관한 것으로 종래의 받침로울러는 주로 금속제로 구성되어 지지판의 축공에 축삽된 회전지지틀이 볼베어링에 의해 회전자재 되도록 하였던 바, 이는 제작비가 많이 소요되어 비경제적이고 사용중 녹이슬게 되면 회동상태가 유연하지 못하고 사용수명도 오래가지 못하였던 바 본 고안은 이러한 종래의 로울러가 갖는 결점을 시정보완하기 위하여 안출한 것으로 이를 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention relates to a support roller of a synthetic resin which allows the rotation direction of the roller to be freely made without a metal bearing ball by improving the structure of a free-rotating support roller attached to the bottom of a large bag or table. The supporting roller is mainly made of metal so that the rotary support frame inserted into the shaft hole of the support plate can be rotated by the ball bearing. This is expensive to manufacture and it is inexpensive. The present invention, which did not last long, was devised to solve the drawbacks of the conventional roller, which will be described in detail with reference to the accompanying drawings.

체결공(1')을 갖는 지지판(1)의 중심부에 단입부(2'), (2")가 형성된 돌환부(2)를 형성하여 바퀴(8)가 달린 지지틀(5)의 단입부(7), (7')를 전기한 단입부(2'), (2")에 접합되게 결합하되 돌환부(2)의 단입부(2'), (2")에 다수의 환상돌기(3), (3')와 종돌조(4), (4')를 돌설하여 이들 환상돌기(3), (3')와 종돌조(4), (4')가 지지틀(5)의 단입부(7), (7')와 축지봉(6)에 접동되게 한 구조이다.The indentation part of the support frame 5 with the wheel 8 is formed by forming the projection part 2 formed with the indentation part 2 'and (2 ") in the center part of the support plate 1 which has the fastening hole 1'. (7) and (7 ') are bonded to the indentations (2') and (2 "), which are described above, and a plurality of annular projections are formed at the indentations (2 ') and (2") of the projection (2). 3), (3 ') and longitudinal projections (4) and (4') protrude through these annular projections (3), (3 ') and longitudinal projections (4), (4') of the support frame (5). It is the structure which made it slide in the stepped parts 7 and 7 'and the axial stick 6.

도면중 미설명 부호 9는 축지봉(6)의 고정용 너트이고, 6'는 이의 괘지홈이다.In the figure, reference numeral 9 denotes a nut for fixing the shaft rod 6, and 6 'is a recessed groove thereof.

이상과 같이된 본 고안은 지지판(1)의 돌환부(2)에 바퀴(8)가 달린 지지틀(5)의 축지봉(6)이 축삽되어 회동 자재되도록 함에 있어서 종래에는 별도의 볼베어링을 삽설하였으나 본 고안은 볼베어링이 없이 돌환부(2)의 단입부(2'), (2")에 돌설환 환상돌기(3), (3')와 종돌조(4), (4')를 지지틀(5)의 단입부(7), (7')와 축지봉(6)에 최소의 마찰면적으로 접동되게 하였기 때문에 합성수지 재질 자체가 갖는 특유의 매끄러운 윤활성에 의해 마찰력에 극미하게 되어 종래와 같은 볼베어링을 삽설하지 않더라도 지지틀(5)의 회동 상태는 극히 유연하게 되며 마모율도 극미하여 로울러의 사용수명도 종래의 철제로된 로울러에 비해 손색이 없고 매우 염가로서 로울러를 제조할 수 있는 효과가 있다.The present invention as described above is conventionally inserted in a separate ball bearing in the shaft rod 6 of the support frame 5 with the wheel 8 is inserted into the pivoting portion 2 of the support plate (1) to be pivoted material. However, the present invention supports the projections 3, 3 'and the bellows 4 and 4' in the indents 2 'and 2' of the projection 2 without ball bearings. Because the sliding area is slid to the indentations 7, 7 'and the shaft rod 6 of the mold 5, the frictional force unique to the synthetic resin itself is minimized to the frictional force. Even if the ball bearing is not inserted, the rotational state of the support frame 5 is extremely flexible, and the wear rate is extremely low. Therefore, the service life of the roller is inferior to conventional steel rollers, and the rollers can be manufactured at a very low cost. .
