<Warp prevention means>
The opening device 100 includes a warp preventing means, and the warp preventing means includes the frame side warp preventing piece 13a and the heel side warping preventing piece 23a.

  In the opening device 100, the door body 20 is fixed by pivot hinges 30 and 40 provided at the upper and lower ends of the door body 20. Therefore, the distance between the upper fixing point for fixing the door 20 and the lower fixing point becomes longer, and the door 20 may be warped. For example, if the opening device 100 is used as an indoor / outdoor partition, a force acts in a direction in which the door 20 is warped in the expected direction due to a negative pressure due to wind-resistant pressure. However, since the opening device 100 is provided with the warp preventing means, the warp can be suppressed. More specifically, when a force that pushes from the indoor side to the outdoor side acts on the door body 20, the heel-side warp prevention piece 23a contacts the frame-side warp prevention piece 13a, and the door body 20 warps in the expected direction. Can be suppressed.

  Thus, in the opening device 100, the warp of the door body 20 is warped by the warp preventing means having the frame side warp preventing piece 13a provided in the vertical frame 13 and the side warping preventing piece 23a provided in the vertical rod 23. Since it can suppress, even if it does not reinforce by thickening the collars 21, 22, 23, and 24, the curvature of the door 20 can be prevented. Accordingly, the flanges 21, 22, 23, and 24 are provided along the outer periphery of the panel 25 so as to cover the end portion and the end surface of the panel 25, and the panel 25 is covered with the flanges 21, 22, 23, and 24. Even if at least a part of the panel 25 and the flanges 21, 22, 23, 24 are bonded by an adhesive means to reduce the size in the direction in which the flanges 21, 22, 23, 24 are found, Warpage of the door 20 can be suppressed.

  When the force that pushes the door 20 to the outside works, the heel-side warpage prevention piece 23a and the frame-side warpage prevention piece 13a must come into contact with each other, so the frame-side warpage prevention piece 13a and the heel-side warpage prevention piece 23a Is provided so that the frame side warpage prevention piece 13a is in front of the heel side warpage prevention piece 23a in front view from the outdoor side in the closed posture of the door body 20, and the frame side warpage prevention piece 13a and A part of the heel side warp preventing piece 23a is provided so as to overlap each other. In the front view from the outdoor side in the closed posture of the door 20, the horizontal length of the portion where the frame side warpage prevention piece 13 a and the heel side warpage prevention piece 23 a overlap obstructs the opening and closing of the door body 20. It is the length which does not come and it is preferable that it is 2 mm or more. If the length is too short, the effect of preventing the door 20 from warping tends to be reduced. In addition, the frame-side warp prevention piece 13a and the heel-side warp prevention piece 23a at a portion where the frame-side warp prevention piece 13a and the heel-side warp prevention piece 23a overlap in a front view from the outdoor side in the closed posture of the door body 20. The distance in the prospective direction is a distance that does not hinder the opening and closing of the door 20, and is preferably 10 mm or less. If the distance becomes too long, the effect of preventing the door 20 from warping tends to be reduced.

  Furthermore, in the front view from the outdoor side, the frame side warpage prevention piece 13a and the heel side warpage prevention piece 23a are provided so as to overlap each other, whereby the frame side warpage prevention piece 13a is provided between the door 20 and the frame body 10. And since it is blocked by the heel-side warp prevention piece 23a, it is possible to improve the heat insulation and improve the design and crime prevention.

  The frame-side warp prevention pieces 13a may extend continuously along the longitudinal direction of the vertical frame 13, or a plurality of the frame-side warp prevention pieces 13a may be provided intermittently. On the other hand, the heel-side warp prevention pieces 23a may extend continuously along the longitudinal direction of the vertical ridge 23, or a plurality of ridge-side warp prevention pieces 23a may be provided intermittently. However, from the viewpoint of productivity, it is preferable that the frame-side warp prevention piece 13a continuously extends along the longitudinal direction of the vertical frame 13, and the heel-side warp prevention piece 23a is It preferably extends continuously along the longitudinal direction.

  Moreover, when the force which pushes the door 20 to the outdoor side act | operates, since the center part of the height direction of the door 20 will move most outdoors, the frame side curvature prevention piece 13a is at least of the vertical frame 13 It is preferable that it is provided at a substantially central portion in the longitudinal direction, and it is preferable that the heel-side warp preventing piece 23 a is provided at least at a substantially central portion in the longitudinal direction of the vertical ridge 23.

  Further, the frame-side warp prevention piece 13a may be manufactured as a separate member from the vertical frame 13 and attached to the vertical frame 13. However, from the viewpoint of productivity and the like, the frame side warp prevention piece 13a is extruded as a member integrated with the vertical frame 13. It is preferable to be manufactured. On the other hand, the heel-side warp prevention piece 23a may be manufactured as a separate member from the vertical rod 23 and attached to the vertical rod 23, but from the viewpoint of productivity and the like, it is extruded as a member integrated with the vertical rod 23. It is preferable to be manufactured.

  3 and 4 exemplify a form in which the horizontal cross-sectional shapes of the frame-side warp prevention piece 13a and the heel-side warp prevention piece 23a are substantially linear, respectively, the warp prevention means is limited to such a form. It is not. The frame side warpage prevention piece and the heel side warpage prevention piece are provided so that the frame side warpage prevention piece is in front of the heel side warpage prevention piece in a front view from the outdoor side in the closed posture of the door body.
