According to the double sliding sash 100 with such a configuration, the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are enclosed within the resin stile body 30 and bonded with the resin stile body 30 to be integrally configured with the resin stile body 30 so as to ensure the strength of the stile body 20. Accordingly, it is not necessary to improve the rigidness of the stile body by providing the three-dimensional core member having the U-shaped or rectangle-shaped cross section, and it is possible to utilize the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 with a reduced cross section. Accordingly, it is possible to ensure the strength of the stile body 20 and configure the stile body 20 in a slim design.
The plate surface 41a, 42b of the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are disposed in the front plane respectively such that it is possible to secure a large area of the portion to receive the wind pressure, that is, the pressure in the indoor-outdoor direction, of the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 in the front plane. Accordingly, it is possible to improve the strength with respect to the wind pressure resistance of the stile body 20. Since it is not necessary to provide the core member outside the glass 29, the width of the stile body 20, that is, a length e in the front plane as shown in Fig. 3 can be set to be small to realize a slim design. The outside of the glass 29 corresponds to the outside in the extension direction, for example, the lower stile 23 may be at the lower side of the glass 29.
The upper end portions 41u, 42u of the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are provided to overlap the glass 29 such that the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 may definitely resist the wind pressure received by the glass 29. Accordingly, the strength of the stile body 20 with respect to the wind pressure may be further improved.
The outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are formed from the metal material such that it is possible to definitely ensure the strength of the stile body 20.
Since the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are disposed in the mating stile 21B, in other words, in the mating portion to which the wind pressure is greatly applied, it is possible to prevent the mating stile 21B from being deformed.
The hollow portion S1 is formed by the connection plate 38, the end plate 37, the lower portion of the outdoor-side second plate 32, and the lower portion of the indoor-side second plate 34. The deformation of the stile body 20 may be absorbed by the hollow portion S1, and it is possible to improve the adiabaticity by the hollow portion S1.
Various shapes or combinations of each configuration member as described in the present embodiment are shown as examples, and various changes based on technical design are possible without departing from the spirit of the present disclosure.
For example, in the above-described embodiment, the plate surfaces 41b, 42b of the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are disposed in the front plane of the resin stile body 30; however, the present disclosure is not limited to the configuration. The plate surface 41a, 42b may be disposed in a depth plane, that is, a plane orthogonal to the front plane. More specifically, the core member may be disposed such that the plate surface is in the horizontal plane in the lower end portion of the lower stile 23, the core member may be disposed such that the plate surface is in the horizontal plane in the upper end portion of the upper stile 22, and the core member may be disposed such that the plate surface is in the vertical plane in the indoor-outdoor direction in the end portion of the width direction of the vertical stile 21.
According to the above-described embodiment, the upper end portions 41u, 42u of the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 overlap the glass 29; however, the present disclosure is not limited to the configuration. The inside end portion of the core member in the front face direction may not overlap the panel member. For example, in the lower stile 23, the upper end portions 41u, 42u of the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 may be disposed at the lower side with respect to the lower end portion 28d of the glass 29.
In the above-described embodiment, the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 are disposed at the two sides in the indoor-outdoor direction to sandwich the glass 29; however, the present disclosure is not limited to the configuration. The core member may be disposed at only one side of the indoor side or the outdoor side of the panel member. In the mating stile 21B, if the core member is configured at only one side in the indoor-outdoor direction of each sliding sash 2, as shown in Fig. 2, it is preferable that the core member is provided in an outdoor-side portion 21c of the outside sliding sash, that is, the sliding sash 2A at the outdoor side, and provided in an indoor-side portion 21d of the inside sliding sash, that is, the sliding sash 2B at the indoor side for resisting the wind pressure.
In the above-described embodiment, the outdoor-side stile 3a and the indoor-side stile 3b enclose the outdoor-side reinforcement portion 41 and the indoor-side reinforcement portion 42 to cover all of the surfaces thereof; however, the present disclosure is not limited to the configuration. The configuration of the resin member enclosing the core member may be an embodiment of exposing one surface of the core member while covering other surfaces of the core member, or an embodiment of exposing part of the core member while covering remaining part of the core member.
As the resin configuring the outdoor-side stile 3a and the indoor-side stile 3b, a thermoplastic resin is preferable, and vinyl chloride resin, chlorinated polyethylene, polystyrene, polypropylene, ABS, AES and the like can be used. A vinyl chloride resin is particularly preferable from the viewpoint of easy molding, bending rigidity and durability.
In the above-described embodiment, the double sliding sash has been described as an example; however, the present disclosure is not limited thereto, and the configuration is applicable to other sashes such as a single sliding door, a sash door or the like.
