Description
제 1 도는 본 고안의 사시도.1 is a perspective view of the present invention.
제 2 도는 본 고안의 전개 상태를 나타낸 단면도.2 is a cross-sectional view showing a developed state of the present invention.
제 3 도는 본 고안의 절첩 상태를 나타낸 단면도.3 is a cross-sectional view showing a folded state of the present invention.
본 고안은 탄력성이 있는 압착 로울러를 체착편의 융출부에 감입 또는 해탈케 하므로서 상다리를 간편히 절첩할 수 있게한 절첩 장치에 관한 것이다.The present invention relates to a folding apparatus that allows the upper and lower legs to be easily folded by intruding or releasing the elastic pressing roller into the fusion portion of the landing piece.
종래에도 단순히 탄발 압착 로울러에 의해 상다리를 전개 및 절첩토록 그 상태를 고정 유지케한 것이 있었으나 이는 단지 탄발 압착 로울러의 회동 여하에 따라 절첩 또는 전개토록 되어 있어 그 탄발 압착 로울러가 상다리의 회전축과는 편심된 곳에 위치하고 있으므로 절첩 작업시 회전축의 직상방은 그 회동반경이 적어지므로서 탄발 압착 로울러 자체에 무리한 힘이 전달되어 지면서 유동 되어야 하므로 로울러를 관착한 중심축은 물론 상판의 체착판이면과의 마찰이 심하게 되어 그 절첩 작업이 부드럽지 못했으며 중심축과의 파손 로울러의 표면마손이 심했으며, 상품이 견고치 무한 결과를 초래했던 것이다.In the related art, there was a case in which the upper leg was fixed and maintained to be simply developed and folded by the elastic crimping roller. However, it is simply folded or developed according to the rotation of the elastic crimping roller so that the elastic crimping roller is eccentric with the rotation axis of the upper leg. Since it is located in the same place, the upper part of the rotary shaft during folding operation should be flowed with excessive force being transmitted to the shot compression roller itself as the rotation radius decreases, so that the friction between the central axis of the roller as well as the top plate of the top plate is severe. As a result, the folding work was not smooth, and the surface of the roller was damaged with the central axis.
본 고안은 상기한 문제점을 시정고져 고안된 것으로 첨부된 예시 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is described in detail with reference to the accompanying drawings as designed to correct the above problems are as follows.
즉 체착판(2)을 가진 축수부(1)에 지각(3)을 회전축(4)에 의해 체착하고 그 상단 전방부에 탄발 압착로울러(5)를 중심축(6)으로 관착 시킨것에 있어서, 축수부(1)의 상면에 호형의 융출부(7)를 압출 성형하고 탄발 압착로울러(5)가 착설된 반대측 지각면에 고무패킹(8)을 착설하여 되는 상다리의 절첩 장치이다.That is, in the case where the crust 3 is attached to the bearing part 1 having the mounting plate 2 by the rotation shaft 4, and the shot compression roller 5 is welded to the central axis 6 at the upper front part thereof, It is an upper leg folding apparatus which extrudes the arc-shaped fusion | melting part 7 on the upper surface of the bearing part 1, and installs the rubber packing 8 on the opposite perceptual surface in which the elastic compression roller 5 was installed.
본 고안의 작동 상태를 설명하면 다음과 같다.Referring to the operating state of the present invention is as follows.
먼저 상다리의 지각(3)을 전개코져 하려면 예시도면 제 2 도에서 보는 바와 같이 지각(3)을 화살표 방향으로 가압하면 지각(3)의 상단 전방부에 관착된 탄발 압착로울러(5)가 중심축(6)을 기점으로 회동 되면서 축수부(1) 상면 전방부의 융출부(7)에 위치 감입되어 고정되는 것이다.First, to develop the upper crust 3 of the upper leg, pressurizing the crust 3 in the direction of the arrow, as shown in FIG. 2 of the drawing, and the shot force roller 5 attached to the upper front of the crust 3 is the central axis. (6) is rotated from the starting point is fixed to the position of the immersion portion 7 of the front surface of the bearing portion (1).
이때 회전축(4)의 전상방 축수부 면판부를 가압시켜 호형의 융출부(7)를 형성 하였으므로 회전축(4)을 기점으로 회전되는 탄발 압착 로울러(5)의 중심축(6)의 회동 반경의 거이 동일하므로 무리한 힘을 받지 않고 중심축(6)이나 체착판(2)이면부에도 마찰 계수가 최대한 적게되어 부드럽게 작동토록 한 것이다.At this time, since the arcuate fusing portion 7 was formed by pressing the face plate portion of the upper and upper bearing portion of the rotating shaft 4, the hooking angle of the rotation radius of the central shaft 6 of the shot compression roller 5 rotated from the rotating shaft 4 as a starting point. Since it is the same, the friction coefficient is reduced as much as possible even when the central axis 6 or the mounting plate 2 is not subjected to unreasonable force, so that it operates smoothly.
이와 같이 전개된 상다리를 절첩코져 하려면 화살표 방향으로 지각(3)을 가압하면 탄발 압착 로울러(5)가 중심축(6)을 기점으로 회동되면서 후방부로 이동되어 결합되는데 이때의 탄발 압착 로울러의 회동 상태는 전개시와 동일한 방법으로 역순되므로 무리한 힘이 전달되지 않고 이동 절첩되는 것이다.In order to fold the developed upper leg, press the crust 3 in the direction of the arrow, and the elastic crimping roller 5 rotates to the rear part while being rotated about the central axis 6, and is coupled to the pivoting crimping roller. Since is reversed in the same way as it is deployed, the force is not folded and is folded.
이렇게 일단 절첩 시키면 지각(3)의 상단에 관착시킨 고무패킹(8)이 지면에 닿게되므로 상을 서로 포개어 적게 하드라도 상판의 표면 지각(3)에 직접 닿아 긁혀지는 등의 문제점을 방지하게 되며 또한 절첩된 상태에서도 상으로서의 역할을 할수 있게되는 것이다.Once folded like this, the rubber packing 8 attached to the upper end of the crust 3 comes into contact with the ground, thus preventing the problems such as scratching by directly touching the surface crust 3 of the top plate even if the images are superimposed on each other. Will be able to act as a prize even in the folded state.
본 고안은 고무 로울러의 회동로를 회동반경과 동일하게 확장시키므로서 절첩전개 작업중 무리한 힘이 가해지므로 해서 파손되거나 작업이 힘들게 되는 등의 문제점을 해결하여 사용이 부드럽고 고장이 없는 상다리를 제공받게 되는 것이다.The present invention extends the rotational path of the rubber roller in the same way as the rotational radius, so that excessive force is applied during the folding and deploying operation, thereby solving problems such as being damaged or difficult to work, thereby providing a smooth and trouble-free upper leg. .
