The rotation nut member 62 and the first male screw portion 52 have a pitch value of 5 mm per rotation and the panel connecting nut member 65 and the second male screw portion 54 have a pitch value of 100 mm or more per rotation Can be employed. The pitch of the threads of the panel connecting nut member 65 and the second male thread portion 54 is formed to be significantly larger than the pitch of the rotating nut member 62 and the first male thread portion 52, 61 can be rotated to operate the folding member 50. That is, when the rotary lever 61 is rotated to rotate the rotary nut member 62, the first nut portion 52 of the linearly moving pin member 51 and the rotary nut member 52 are screw- The linear moving pin member 51 including the first male screw portion 52 is linearly moved as described above by the rotation of the member 62. [ When the linearly moving pin member 51 is moved in the axial direction as described above, the second male screw portion 54 of the linearly moving pin member 51 also moves in the axial direction and is screwed to the panel connecting nut member 65, And the upper side wall panels 31 and 41 connected to the panel connecting nut member 65 are rotated and folded. In addition, in addition, each thread is formed of a trapezoidal thread and the pitch of the first male thread portion 52 is formed to be significantly smaller than that of the second male thread portion 54, so that it can be operated with relatively small force.

제2수나사부(54) 후방측의 직선 이동핀부재(51)의 후단부(55)는 판넬연결 너트부재(65)의 일측부분과 하부 측벽 판넬(31)의 힌지연결부(57)에 축결합된다.The rear end portion 55 of the linear moving pin member 51 on the rear side of the second male screw portion 54 is axially coupled to one side portion of the panel connecting nut member 65 and the hinge connecting portion 57 of the lower side wall panel 31 do.

이하에서는 상기와 같은 구성을 가지는 본 발명에 따른 접이식 컨테이너의 작동방법에 대해 설명한다. 먼저 접이식 컨테이너가 세워진 상태(도4)에서 접는 동작을 설명하면 도3에서와 같이 회전레버(61)가 회전너트부재(62)에 결합된 상태에서 회전레버(61)를 회전시키면 회전너트부재(62)가 수용부(63)에 수용된 상태에서 제자리에서 회전하게 된다. 회전너트부재(62)가 이와 같이 회전되면 제1수나사부(52)가 회전너트부재(62)와 결합된 직선 이동핀부재(51)는 반대쪽으로 이동하게 되는데, 안내핀(53b)이 길이방향으로 형성된 안내홈(53a)에 결합되어 직선 이동핀부재(51)가 축방향으로 이동된다(도3 참조). Hereinafter, a method of operating the folding container according to the present invention will be described. 3, when the rotary lever 61 is rotated in a state where the rotary lever 61 is coupled to the rotary nut member 62, the rotation nut 61 (FIG. 4) 62 are housed in the accommodating portion 63 and rotate in place. When the rotation nut member 62 is rotated in this manner, the linear movement pin member 51, which is engaged with the rotation nut member 62 by the first male screw portion 52, moves in the opposite direction. When the guide pin 53b moves in the longitudinal direction And the linearly moving pin member 51 is moved in the axial direction (see FIG. 3).

이와 같이 직선 이동핀부재(51)가 반대쪽(도3에서 화살표 방향)으로 이동하게 되면 직선 이동핀부재(51)의 제2수나사부(54)에 결합된 판넬연결 너트부재(65)가 회전하게 되고 판넬연결 너트부재(65)와 연결된 상부 측벽 판넬(31, 41)이 도5에서와 같이 회전하여 하부 측벽 판넬(32, 42) 쪽으로 회전하여 접히게 된다. 3), the panel connecting nut member 65 coupled to the second male threaded portion 54 of the linearly moving pin member 51 rotates (in the direction of arrow in FIG. 3) The upper side wall panels 31 and 41 connected to the panel connecting nut member 65 rotate as shown in FIG. 5 and are turned toward the lower side wall panels 32 and 42 to be folded.

도6은 상부 측벽 판넬(31, 41)이 하부 측벽 판넬(32, 42)과 완전히 접힌 상태를 도시한 것으로 탈부착가능한 회전레버(61)를 회전너트부재(62)로부터 분리시킨 상태를 도시한 것이다. 6 shows a state in which the upper side wall panels 31 and 41 are completely folded with the lower side wall panels 32 and 42 and the detachable rotation lever 61 is separated from the rotation nut member 62 .

반대로 접이식 컨테이너가 접힌 상태에서 펴기 위해서는 회전레버(61)를 회전너트부재(62)에 결합시킨 상태에서 전술한 접는 과정과 반대방향으로 회전레버(61)를 회전시키고, 이에 따라 상부 측벽 판넬(31, 41)이 하부 측벽 판넬(32, 42)로부터 멀어지는 방향으로 회전되어 접이식 컨테이너가 세워지게 된다. 한 쌍의 측벽 판넬(30, 40)이 완전히 펼쳐져 수직하게 세워지면 측벽 판넬(30, 40)에 구비된 클램프와 같은 미도시된 록킹장치를 이용하여 상, 하부 측벽 판넬(31, 32)을 수직상태로 고정시키게 된다. 본 발명에서 절첩부재(50)의 작동은 편의상 하나의 절첩부재를 예로 들어 설명하였으나, 접이식 컨테이너를 접거나 펼칠 때 하나의 측벽 판넬(30, 40)의 양측에 구비되는 절첩부재(50)를 동시에 작동시키거나 양 측벽 판넬(30, 40)에 구비되는 절첩부재(50)를 동시에 작동시켜 컨테이너를 접고 펼 수 있다.On the contrary, in order to open the folding container in the folded state, the rotation lever 61 is rotated in the direction opposite to the folding process described above while the rotation lever 61 is coupled to the rotation nut member 62, 41 are rotated away from the lower sidewall panels 32, 42 to raise the foldable container. When the pair of sidewall panels 30 and 40 are completely opened and vertically erected, the upper and lower sidewall panels 31 and 32 are moved vertically using a locking device such as a clamp provided on the sidewall panels 30 and 40 As shown in FIG. The operation of the folding member 50 in the present invention has been described by taking one folding member as an example for the sake of convenience. However, when the folding container is folded or unfolded, the folding member 50 provided on both sides of one of the side wall panels 30, The folding members 50 provided on both side wall panels 30 and 40 can be simultaneously operated to fold and unfold the container.

또한, 본 발명에서는 회전너트부재(62) 및 제1수나사부(52)의 나사산의 피치가 판넬연결 너트부재(65) 및 제2수나사부(54)의 피치보다 현저하게 작게 형성됨으로써 작은 힘으로 회전레버(61)를 회전시켜 절첩부재(50)를 작동시킬 수 있다. 그리고, 회전너트부재(62) 및 제1수나사부(52)의 피치가 판넬연결 너트부재(65) 및 제2수나사부(54)의 나사산의 피치보다 현저하게 작게 형성되어 회전너트부재(62)의 회전에 의해서만 직선 이동핀부재(51)가 이동가능하게 됨으로써 회전너트부재(62)의 회전을 멈출 시에 자세가 유지되어 보다 안정적이고 비교적 작은 힘으로 접고 펼 수 있게 된다.In the present invention, since the pitches of the threads of the rotation nut member 62 and the first male screw portion 52 are formed to be significantly smaller than the pitches of the panel connecting nut member 65 and the second male screw portion 54, The rotation lever 61 can be rotated to operate the folding member 50. [ The pitch of the rotation nut member 62 and the first male screw portion 52 is formed to be significantly smaller than the pitch of the threads of the panel connecting nut member 65 and the second male screw portion 54, The linear moving pin member 51 can be moved only by the rotation of the rotating nut member 62, so that the posture is maintained when the rotation of the rotating nut member 62 is stopped, so that it can be folded and unfolded with a relatively small force.

이상, 본 발명을 바람직한 실시예를 참조하여 설명하였으나, 본 발명은 이에 한정되지 아니하고, 당해 기술분야의 당업자는 하기의 특허청구범위에 기재된 본 발명의 요지를 벗어나지 않는 범위 내에서 다양한 변형이 가능할 수 있을 것이다.
