본 고안은 절첩식 의자의 다리 끝단부분에 간편하게 연결시켜 무게의 균형을 바닥원판의 중심선상으로 집중시켜 바닥과의 미끄럼을 방지시켜 주는 다리 연결 받침구에 관한 것이다.The present invention relates to a leg connection support that can be easily connected to the leg end of the folding chair to balance the weight on the centerline of the floor disc to prevent slipping with the floor.
지금까지의 연결 받침구는 도면 제 4 도에서 보는 바와 같이 받침구에 미치는 무게의 균형을 중심쪽으로 치중하고져 상부지주관을 중심에서 일측으로 편중시키고 다리 하단과 연결하는 "ㄱ"형 연결지지대를 중심쪽으로 이동시켰으나 받침구의 땅에 닿는 단위면적이 작아 무게의 중심을 받침구의 바닥원판에 분포시키기가 어렵고 파손시 다른 받침구와 교체시켜야 되는 불편이 있었다.As shown in FIG. 4, the connecting base is focused on the balance of the weight on the base, and the upper support pipe is centered on one side and connected to the bottom of the leg. Although it moved, it was difficult to distribute the center of weight to the bottom disc of the support, because the unit area touching the ground of the support was small, and there was an inconvenience to replace it with another support.
본 고안에서는 이와 같은 문제점을 해소하고져 바닥원판의 상부중앙에 지주관을 형성시키고 이 지주관을 중심으로 네개의 연결지지대를 직각이 되게 입설시키되 이 연결지지대와 연결하는 다리 하단의접속면이 지주관의 90°각도 중심선상에 유지하도록 교차된 중심선상의 일측 방향으로만 편중되도록 입설시켜 두개의 다리 하단이 "ㄱ"형으로 연결구의 연결지지대와 접속연결될때 두개가 모두 연결구의 중심선상에서 상호 접속되어 무게가 중심선상으로 집중되어 균형을 유지시킬 수가 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention to solve this problem, to form a holding tube in the upper center of the bottom disc and to install the four connecting supports at a right angle centering around the holding tube, the connection surface at the bottom of the bridge connecting the connecting support is a holding tube The two legs are interconnected on the centerline of the connector when the bottom of the two legs is connected to the connector support of the connector in the form of "a" so that it is biased only in one direction on the intersected centerline to maintain the 90 ° angle of the centerline. The weight is concentrated on the center line to maintain the balance will be described in detail based on the drawings as follows.
바닥원판의 상부중앙에 위치한 지주관(1)의 90°각도로 교차된 중심선을 중심으로 네개의 연결지지대(2)를 모두 중심선상에 일측면이 접하도록 일측방향으로 편중되게 입설시키고 저면의 가장자리는 다수의 돌기(3)를 일정한 간격으로 형성시키고 내부중앙의 함입단(4)에는 미끄럼방지용 고무판(5)을 부착시켜서된 것으로 미설명부호(2')는 연결공이다.The four connecting supports (2) are centered on one side so as to contact one side on the center line and centered on the center line intersected at 90 ° angle of the support pipe (1) located in the upper center of the bottom disc. Is formed by attaching a plurality of projections (3) at regular intervals and attached to the inner end of the recessed end (4) of the anti-slip rubber plate (5), reference numeral 2 'is a connection hole.
이와 같은 구조로 된 본 고안은 네 개의 연결지지대(2)를 바닥원판의 상부 중앙에 위치한 지지관(1)의 90°각도로 교차된 중심선상의 일측방향으로만 편중되게 입설시켰으므로 두개의 다리 하단과 "ㄱ"형으로 연결지지대(2)의 연결공(2')과 연결시 그 양접속면이 중앙지주관의 중심선상에서 "ㄱ"형으로 접속되므로 무게의 하중이 받침구의 중심선상으로 집중되어 균형이 유지가 되고 일측 연결지지대가 파손시에도 타측의 연결지지대를 이용하여 연결시킬 수 있으며, 특히 바닥면에 닿는 저면의 가장자리에는 다수의 돌기(3)를 형성시키고, 내향의 함입단(4)에는 고무판(5)을 부착시켰으므로 미끄러운 바닥면에는 고무판이 접착되고 약간 경사면에서는 가장자리의 돌기에 의하여 미끄러지는 것을 방지시켜 주도록 된 것이다.The present invention having such a structure allows the four legs to be biased in one direction only on one side of the center line intersected at 90 ° angle of the support tube 1 located at the upper center of the bottom disc. When connecting with the connecting hole (2 ') of the connecting support (2) in the bottom and the "a" shape, the connection surface is connected to the "b" shape on the center line of the central support pipe, so that the load of the weight is concentrated on the center line of the base. When the balance is maintained and one side connection support is damaged, it can be connected by using the other side support support, and in particular, a plurality of protrusions (3) are formed at the edges of the bottom facing the bottom surface, and the inwardly indented end (4) Since the rubber plate 5 is attached to the rubber plate, the rubber plate is adhered to the slippery surface, and on the slightly inclined surface, the rubber plate 5 is prevented from slipping by the projection of the edge.
