Then, while the vertical frame 6 is opened, the load F applied to the guide protrusion 8 from the intermediate door contact piece 10 is dispersed, and a component force is generated in the in-plane direction of the external shoji 2 so that the door of the external shoji 2 comes off. There is a problem that it is easy. On the other hand, it is conceivable to improve the strength of the vertical frame 6 to prevent the vertical frame 6 from being opened and to prevent the door of the shoji 2 from coming off. Will rise. The same applies to the shoji 3.
[0006]
The present invention has been made in view of such circumstances, and an opening device that can easily and inexpensively prevent the door of the shoji from coming off when pressurized from the indoor side to the outdoor side. The purpose is to provide.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an opening device according to claim 1 includes a frame and a shoji that is housed in the frame so as to be movable in the left-right direction.

[0008]
In the first aspect of the invention, the outdoor side is pressurized from the indoor side to the outdoor side, for example, by a negative pressure, and the shoji bends so as to protrude to the outdoor side. When the piece of the sliding door is in an inclined state, the slope of the sliding piece of the sliding door is pressed against the guide protrusion of the vertical frame of the frame in a surface contact state. If it does so, since the load applied to a guide protrusion from an intermediate door contact piece will not be disperse | distributed and a component force will not arise in the surface direction of a shoji, it will become difficult to remove the door tip of a shoji. Therefore, it is possible to prevent the door of the shoji from coming off easily and inexpensively without increasing the strength of the vertical frame of the frame.
[0009]
The opening device according to claim 2 is the invention according to claim 1, wherein an upper door piece and a lower door piece are respectively attached to upper and lower ends of the door-end side vertical fence.

Yes. As described above, the external shoji B is a shoji that arranges the synthetic resin frame members 46, 47, and 48 on the indoor side to achieve high-performance heat insulation and enhance the interior of the indoor side.
[0015]
As shown in FIG. 3, an upper door end piece 53 and a lower door end piece 54 are respectively attached to the upper and lower end portions of the door-end side vertical rod 43, and the vertical intermediate portion is spaced apart. Two intermediate door stop pieces 55 and 55 are attached.
As shown in FIGS. 1 and 4, the intermediate door contact piece 55 is fitted and fixed to a door-end side vertical rod 43 and a synthetic resin frame member 48. In order to more firmly fix the intermediate door contact piece 55, it may be screwed to the door end side vertical rod 43. The intermediate door end piece 55 is formed of a synthetic resin in a substantially L-shaped plate shape, and includes an abutting surface 56 extending in the indoor / outdoor direction and a vertical frame 23 on the left side of the frame A of the abutting surface 56. It is formed between the abutting surface 56 and the slanted surface 57, which is formed at a position closer to the vertical frame 23, and is formed between the abutting surface 56 and the slanted surface 57. And an inclined surface 58 gradually toward the outdoor side.
The upper door stopper piece 53 and the lower door stopper piece 54 are formed in the same manner as the intermediate door stopper piece 55, and are fitted to the door-end side vertical rod 43 and the synthetic resin frame member 48 and fixed by screwing. .
[0016]
The upper door-stop piece 53, the lower door-door piece 54, and the intermediate door-door piece 55 are formed on the guide protrusion 31 of the vertical frame 23 when the outer door B is closed. 54 and the intermediate door-contacting piece 55 come into contact with each other so that the door-end side spatula 43 is brought to the indoor side, and in the state in which the shoji B is completely closed, the upper door-contacting piece 53 The abutting surfaces 56 of the lower door end piece 54 and the intermediate door end piece 55 are abutted against the tip of the guide protrusion 31.
[0017]
The inner shoji C is configured in the same manner as the outer shoji B. That is, an upper eave 61, a lower eave 62, a door end side eave 63 and a summing eave 64 made of an aluminum alloy extruded shape, and a synthetic resin frame respectively disposed on the indoor side of each eave A square ridge assembly 70 is assembled by the members 66, 67, 68, and 69, and the multilayer glass 51 is incorporated in the ridge assembly 70. As described above, this inner shoji C is also a shoji with a synthetic resin frame member 66, 67, 68, 69 arranged on the indoor side to achieve high-performance heat insulation and an improved interior property on the indoor side. .
[0018]
Similarly to the case of the shoji B, the upper door stop piece 53, the lower door stop piece 54 and the two intermediate door stop pieces 55 are attached to the doorside side spatula 63 of the inner shoji C. When closing, each inclined surface 57 of the upper door contact piece 53, the lower door contact piece 54, and the intermediate door contact piece 55 hits the guide protrusion 32 of the vertical frame 24 on the right side of the frame A, and the door end side. The vertical fence 63 is brought closer to the indoor side, and in the state in which the inner shoji C is completely closed, the abutting surfaces 56 of the upper door stopper piece 53, the lower door stopper piece 54, and the intermediate door stopper piece 55 are It is abutted against the tip of the guide protrusion 32.
[0019]
In the sliding sash constructed as described above, as shown in FIG. 5, the outdoor side is pressurized from the indoor side to the outdoor side, for example, by a negative pressure, and the entire shoji protrudes to the outdoor side. When the piece 55 of each of the intermediate doors of the outer cover B and the inner cover C is inclined with the warp deformation of the outer cover B and the inner cover C, as shown in FIG. The inclined surface 58 of the intermediate door stop piece 55 of the outer panel B is pressed against the guide protrusion 31 of the vertical frame 23 of the body A in a surface contact state. Then, the load F applied to the guide protrusion 31 from the intermediate door contact piece 55 is not dispersed, and no component force is generated in the in-plane direction of the outer panel B, so that the door tip of the outer panel B is difficult to come off. The same applies to the upper door stop piece 53 and the lower door stop piece 54. In addition, since the warp deformation is larger in the vertical middle part of the external shoji B than in the upper part and the lower part, the case of the intermediate door stopper piece 55 is larger than the upper door stopper piece 53 and the lower door stopper piece 54. A load acts.
[0020]
The same applies to the inner shoji C as in the case of the outer shoji B. That is, when the upper door stopper piece 53, the lower door stopper piece 54, and the intermediate door stopper piece 55 of the inner impingement C are in an inclined state, each door stopper piece of the inner impeller C is placed on the guide protrusion 32 of the vertical frame 24 of the frame A. Since the slope 58 is pressed in a state of surface contact, the door of the inner shoji C is difficult to come off.
Accordingly, it is possible to easily and inexpensively prevent the doors of the outer shoji B and the inner shoji from coming off without increasing the strength of the vertical frames 23 and 24 of the frame A.
[0021]
In the above-described embodiment, the upper door stop piece 53, the lower door stop piece 54, and the intermediate door stop piece 55 are formed with the inclined surfaces 58. The warp deformation of the portion is smaller than the intermediate portion in the vertical direction, and the acting load is also small. Therefore, the upper door piece 53 and the lower door piece 54 do not form the inclined surface 58, and only the intermediate door piece 55 is inclined. 58 may be formed.
[0022]
Moreover, in the above-mentioned embodiment, although each inclined surface 57 of each door stop piece was formed with the curved surface, you may make it form with a plane (slope). Moreover, each slope 58 of each door stop piece may be flat, and a recess, a groove | channel, etc. may be formed in part or the whole surface. In short, when each door stop piece is in an inclined state in accordance with the warp deformation of the outer shoji B and the inner shoji C, the slope 58 is pressed against the guide protrusions 31 and 32 in a substantially surface contact state. If so.
[0023]
Moreover, although the above-mentioned embodiment demonstrated the case where it applied to the composite sash which consists of a metal and a synthetic resin, this invention is applicable also to a metal sash or a synthetic resin sash.
Further, in the above-described embodiment, the case where the present invention is applied to the two-seat differential sash provided with the external obstacle B and the internal imperial C is described. The present invention can be applied to a sash or the like.
[0024]
That is, the present invention includes a frame body and a shoji that is housed in the frame so as to be movable in the left-right direction, and a guide protrusion is provided on the vertical frame of the frame body facing the door-end side vertical shaft of the shoji screen. In addition, the present invention can be applied to an opening device in which a door-stop piece is attached to the door-end side downarm.
[0025]
【The invention's effect】
As described above, according to the opening device of the first aspect, pressure is applied from the indoor side to the outdoor side, the shoji is curved so as to protrude to the outdoor side, and the intermediate door contact piece of the shoji is inclined. When this happens, the slope of the sliding door's intermediate door contact piece is pressed against the guide protrusion on the vertical frame of the frame in a surface contact state, so the load applied to the guide protrusion from the intermediate door contact piece is not dispersed. Since no component force is generated in the in-plane direction of the shoji, it is difficult for the shoji door to come off. Therefore, it is possible to prevent the door of the shoji from coming off easily and inexpensively without increasing the strength of the vertical frame of the frame.
[0026]
According to the opening part apparatus of Claim 2, since the slope is formed in the upper door contact piece and the lower door contact piece of the upper and lower ends of a door-end side vertical wall, it pressurizes from the indoor side to the outdoor side. When this is done, it is possible to further prevent the door of the shoji from coming off.
