본 고안은 절첩식 밥상등에 사용되는 절첩식 상다리에 관하여 특히 상판 저면에 회동 가능하게 설치되는 지자각을 한쌍의 절첩링크로 된 버팀칸으로써 견고하게 지지토록 한 접첩식 상다리에 관한 것이다.The present invention relates to a folding leg for supporting a folding leg to be used as a pair of folding links, especially a folding leg installed on the bottom of a top plate.
종래 절첩식 상다리는 상판의 저면에 한쌍의 지지각을 회동 절첩 가능하게 설치한 절첩식과, 이들 지지각을 한쌍의 절첩링크로된 버팀간으로 견고하게 지지토록 한 이중 절첩식이 사용되고 있었다.Conventionally, a folding type leg has been used in which a pair of supporting angles can be pivotally installed on the bottom of a top plate, and a double folding type which firmly supports these supporting angles with a pair of folding links.
그러나 전자의 경우에는 4개의 지지각에 각각 탄성록크장치를 설치하여 절첩시 일일이 탄성록크장치를 해지하면서 절첩시켜야 하므로 사용이 번거움뿐 아니라, 지지각은 탄성록크장치에 의해 상단부(상판과의 연결부분)에서만 록크 및 지지되므로 지지격이 약하여 사용중 상이 넘어질 염려가 있었으며, 또한 사용에 따라 반성록크장치가 쉽게 마모되거나 변형되어 절첩 불능 또는 록크불능상태로 되는 등 사용수명이 짧게 되는 폐단이 있었다.However, in the former case, the elastic lock device must be installed on each of the four support angles, and the folding angle must be folded while the elastic lock device is released. Because of the locking and support only in the part), there was a fear that the phase would fall during use due to the weak support, and the use life of the semi-locking device could be easily worn or deformed, resulting in a shortened service life.
또한 후자의 경우에는 상판 저면에 한쌍의 지지각을 횡간으로 연결한 상태로 회동 절첩 가능하게 설치하고, 상판 저면과 횡간 사이에 한쌍의 절첩링크로 된 버팀칸을 설치하여 상다리를 펼쳤을때 지지각이 상판에 대해 버팀간으로써 삼각 지지상태로 되도록 한 것으로 전자와 같은 폐단을 해소될 수 있었으나, 버팀간의 하부링크와 횡간을 회동 가능하게 연결함에 있어 하부 링크와 횡간사이에 별도의 회동 연결구를 설치하였으므로 구조 및 조립 제작이 복잡하고 번거롭게 될 뿐 아니라, 버팀간을 펼칠때 상, 하부링크의 연결부위를 엄지손가락등으로 눌러야 하는 바, 이때 상, 하부 링크사이에 엄지손가락등이 끼어 들어가서 부상을 당하기 쉬운 폐단이 있었다.In the latter case, when the upper leg is extended by installing a pair of folding links between the bottom of the upper plate and the transverse side, it is possible to fold it in a state where the pair of support angles are connected horizontally. It was possible to solve the closed end like the former by making the triangular support state by supporting the upper plate, but in order to connect the lower link and the transverse rotation between the brace so that a separate rotational connector was installed between the lower link and the transverse structure. And as the assembly fabrication is not only complicated and cumbersome, but also when you push the brace between the upper and lower links should be pressed with a thumb, etc. At this time, the thumb is caught between the upper and lower links, which is easy to get injured. There was this.
따라서 본 고안은 이러한 종래의 재반 폐단을 해소하기 위하여 이중 절첩식 상다리에서의 장점을 그대로 발휘할수 있음은 물론 버팀간의 하부 링크하단을 만곡하여 보스부를 일체로 형성함으로써 구조와 조립 제작을 간단하고 편리하게 함과 아울러 하부 링크의 상단부에 부상 방지용 연장부를 형성함으로써 사용중 사용자가 부상을 입는일이 없도록 하려는 것이다.Therefore, the present invention can realize the advantages of the double folding upper legs as it is to eliminate such conventional re-closing, as well as forming the boss unit by bending the lower link between the braces, making the structure and assembly fabrication simple and convenient. In addition, by forming an extension for preventing injury on the upper end of the lower link to prevent the user from being injured during use.
이하 본 고안을 첨부도면에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도시한 바와 같이, 횡간(2)으로 연결된 한쌍의 지지각(1)의 상단부를 지지편(3)으로써 상판(P)저면에 지지하고, 한쌍의 절첩링크(5)(6)로 된 버팀간(4)의 상부링크(5)상단을 지지편(7)으로 상판(P)저면에 연결하고, 하부링크(6) 하단을 횡간(2)에 회동가능하게 연결한 것에 있어서, 상기 버팀간(4)의 하부링크(6) 하단에는 횡간(2)에 연결되는 보스부(8)를 일체로 만곡 형성하며, 하부링크(6)의 상단부에는 부상방지용 연장부(9)를 연장 형성하여서 된 것이다.As shown, the upper end of the pair of support angles 1 connected by the transverse 2 is supported by the support piece 3 on the bottom of the top plate P, and the brace between the pair of folding links 5 and 6 is provided. The upper end of the upper link (5) of (4) is connected to the bottom of the upper plate (P) by the support piece (7), and the lower link (6) is connected to the transverse (2) so as to be rotatable. The lower link 6 of the 4) is formed by integrally curved boss portion 8 connected to the transverse 2, the upper end of the lower link (6) is formed by extending the extension portion 9 for preventing injury. .
미설명부호 3는 지지편(3)에 형성된 정지돌기이며, 10은 지지각(1) 하단에 끼워진 받침 고무편이고, 11은 지지편(3)에 지지각(1)을 연결하는 축핀이며, 12는 상부링크(5)와 하부링크(6)를 연결하는 축핀이고, 13은 상부링크(5)를 지지편(7)에 지지하는 축핀이다.Reference numeral 3 is a stop projection formed on the support piece 3, 10 is a support rubber piece fitted to the lower end of the support angle (1), 11 is a shaft pin connecting the support angle (1) to the support piece (3), 12 Is an axial pin for connecting the upper link 5 and the lower link 6, 13 is an axial pin for supporting the upper link 5 to the support piece (7).
이와 같이 구성된 본 고안의 절첩식 상다리는 버팀간(4)의 하부링크(6) 하단과 횡간(2)을 회동되게 연결함에있어 별도의 연결구를 사용하지 않고 하부링크(6) 하단에 보스부(8)를 일체로 만곡형성하였으므로 구조가 간단하고 조립제작이 간편하게 된다.In this way, the folded upper leg of the present invention is configured to pivotally connect the lower link 6 and the transverse 2 of the brace rod 4 without the use of a separate connector. Since 8) is integrally curved, the structure is simple and assembly manufacturing is simple.
사용에 있어서는 제1도의 좌측표시 및 제2도의 1점 쇄선표시와 같이 절첩식 상태에서 지지각(1)을 회동시켜 펼쳐서 제1도의 우측표시 및 제2도의 실선표시 상태로하여 사용하며, 다시 반대 방향으로 회동시켜 제1도의 좌측표시 및 제2도의 1점 쇄선표시 상태로 절첩하여 보관하는 것으로, 사용중에는 지지각(1)이 버팀간(4)에 의해서 상판(P)에 대해 삼각 지지상태로 되므로 견고하게 지지되며 각 지지점에서는 하등 무리가 가지 않으므로 기능고장을 일으킬 염려가 없다.In use, as shown in the left side of FIG. 1 and the dashed-dotted line of FIG. 2, the support angle 1 is rotated and unfolded in a folded state, and the right side of FIG. 1 and the solid line of FIG. 2 are used. And rotated in the direction shown in FIG. 1 to the left and the dashed-dotted line shown in FIG. 2 to be stored, and in use, the support angle 1 is held in a triangular support state with respect to the upper plate P by the brace 4. Therefore, it is firmly supported and there is no fear of malfunction because there is no inferior force at each support point.
지지각(1)을 펼침에 있어서는 제2도의 1점쇄선상태(절첩상태)에서 지지각(1)을 회동시키면 상판(P)과 횡간(2) 사이에 연결된 버팀간(4)의 상, 하부링크(5)(6)가 벌어지게 되며, 지지각(1)을 쇄선 표시상태로 완전히 펼친 상태에서는 버팀간(4)은 상, 하(5), (6)가 일직선상태(즉 死點위치)까지 펼쳐지며 이때 하부링크(6)의 상단부(버팀간(4) 전체로 볼때에는 중간 연결부분을 눌러서 상, 하부 링크(5),(6)가 사점에서 벗어나게 하면 되는바, 여기서 하부링크(6)의 상단부를 누를때 부상방지용 연장부(9)가 형성되어 있으므로 사용자의 엄지 손가락등이 상, 하부링크(5)(6)사이에 끼어 부상을 입는 일이 없게 되는 것이다.In unfolding the support angle 1, when the support angle 1 is rotated in the dashed-dotted state (folded state) of FIG. 2, the upper and lower portions of the brace 4 connected between the upper plate P and the transverse 2 The links (5) and (6) are opened, and in the state where the support angle (1) is fully extended in the dashed line display state, the upper and lower (5) and (6) are in a straight state (ie The upper link of the lower link (6) (when viewed as a whole between the braces (4) in the middle of the connecting portion by pressing the upper, lower links 5, 6) out of the dead center bar, where the lower link (6 When pressing the upper end of the injury prevention extension (9) is formed so that the user's thumb is caught between the upper, lower links (5) (6) to avoid injury.
사용을 마치고 절첩함에 있어서는 버팀간(4)의 상, 하부링크(5)(6)를 다시 반대방향으로 눌러서 사점을 벗어나서 약간 절첩되게 한 다음 지지각(1)을 절첩하면 되며 이때 버팀간(4)도 절첩되는 것이다.When folding after use, press the upper and lower links (5) and (6) in the opposite direction again in the opposite direction to slightly fold out of the dead point, and then fold the support angle (1). ) Is also folded.
이상과 같이 본 고안에 의하면 지지각이 견고하고 안정되게 지지되며 절첩조작이 간편하게 됨은 물론, 구조 및 조립제작이 간편하고 지지각을 펼칠때 사용자가 엄지손가락등에 부상을 입는 일이 없게 되는 효과가 있다.As described above, according to the present invention, the support angle is firmly and stably supported, and the folding operation is simple, as well as the structure and assembly manufacturing are simple, and when the spreading angle is extended, the user is not injured on the thumb. .
