Description

The present invention relates to a fitting provided with an external sash that is slidable on the outdoor side and an internal sash that is slidable on the indoor side.

Conventionally, fittings such as sliding windows have been known to have a structure for preventing rainwater from entering from the outdoor side. Patent Document 1 discloses this kind of technology.

According to Patent Document 1, the space of the meeting part is an isobaric space equal to the outdoor space, and even if rainwater accompanied by a strong wind blows from the gap between the lower frame and the internal sash, the rainwater will exceed it. Described is a configuration that is blocked by an AT material having a height dimension that cannot be achieved. As a result, it is possible to prevent rainwater from entering the indoor space from the inside and outside of the combination stile and improve the watertightness.

By the way, in fittings such as sliding windows, rainwater or the like enters between the outer sash located on the outdoor side and the inner sash located on the indoor side, and the smoke return formed on the found surface on the indoor side of the outside stile. As a result, water may leak to the lower frame and flow into the room. In a sash with high watertightness, a drainer or the like is provided to prevent water from entering, but it is difficult to completely eliminate the gap. In particular, on the upper floors of a building, if there is air leakage due to strong winds, water may be drawn into the room and water leakage may easily occur. There was room for improvement in conventional fittings in terms of further improvement in watertightness.

Next, the detailed configuration of the outer smoke return portion 435 of the external shoji 40 will be described. FIG. 8 is an enlarged front view showing the lower end portion of the outer smoke return portion 435 of the external shoji 40 of the present embodiment. FIG. 8 shows the lower end portion of the outer smoke return portion 435, and schematically shows how water falls along the finding surface 435a of the outer smoke return portion 435.

As shown in FIG. 8, the outer smoke return portion 435 is continuous in the vertical direction without interruption. The tip surface of the outside smoke return portion 435 on the indoor side in the finding direction is formed as a vertical portion 435b extending linearly in the vertical direction.

The corners on the indoor side in the finding direction of the outer smoke return portion 435 are chamfered to form an inclined portion 70. The upper end 70a of the inclined portion 70 is connected to the vertical portion 435b, and the lower end portion 70b of the inclined portion 70 is connected to the horizontal portion 435c extending to the outdoor side in the finding direction.

The inclined portion 70 is inclined so as to proceed toward the vertical frame 14 in the finding direction as it descends from the upper end portion 70a. In the present embodiment, the upper end portion 70a of the inclined portion 70 is located on the indoor side in the finding direction rather than the center in the width direction of the indoor side finding surface 430a in the outer stile 43. The lower end portion 70b of the inclined portion 70 is positioned so as not to overlap the lower frame windbreak plate 60 in the vertical direction. Further, the upper end portion 70a and the lower end portion 70b have a slightly rounded shape.

In the present embodiment, from the viewpoint of safety, the upper end portion (not shown) of the outside smoke return portion 435 on the door end side is R-processed. The upper end surface of the outer smoke return portion 435 is horizontal, and the position of the starting end portion (outdoor end portion in the finding direction) where the R portion starts is the lower end portion 70b (room in the finding direction) of the inclined portion 70. It is on the indoor side in the finding direction with respect to the position of the outer end). The configuration of the upper end portion of the outside smoke return portion 435 on the door end side can be changed as appropriate depending on the circumstances, such as changing the shape of the R portion or omitting the R portion.

According to the above embodiment, the following effects are obtained.
The outer sash 40 included in the fitting 1 of the present embodiment is arranged on the outer stile 43 located on the outdoor side and the indoor side finding surface 430a of the outer stile 43, extends to the indoor side in the prospect direction, and then the outer sash 40. It is provided with an outer smoke return portion 435 that bends to the door end side of the door, and an inclined portion 70 is formed on the door end side of the outer shoji 40 of the outer smoke return portion 435 toward the opposite side of the outer shoji 40 as it goes down. Will be done.

As a result, even if rainwater or the like descends along the finding surface 435a of the outside smoke return portion 435, the inclined portion 70 can guide water droplets to the outdoor side in the finding direction of the outside stile 43, so that the outside smoke can be guided. It is possible to effectively prevent the water that has traveled through the return portion 435 from falling downward as it is and moving to the indoor side through the lower frame 12 to cause water leakage. Further, since the inclined portion 70 eliminates the corner portion of the lower end portion of the outer smoke return portion 435 located on the tip end side in the moving direction, the safety is also improved.

Further, in the present embodiment, the lower frame windbreak plate (lower frame windbreak member) 60 is attached to the lower frame 12, and the lower end portion 70b of the inclined portion 70 is in the finding direction with respect to the lower frame windbreak plate 60. It is a position on the outdoor side of the building that does not overlap in the vertical direction.

As a result, it is possible to effectively prevent the occurrence of a situation in which the water that has fallen through the outside smoke return portion 435 exceeds the lower frame windbreak plate 60 and moves to the indoor side in the finding direction.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment and can be appropriately modified.

In the above embodiment, an example in which the inclined portion 70 is formed linearly has been described, but the present invention is not limited to this configuration. For example, the lower end portion of the outer smoke return portion 435 may be bent in an arc shape to guide rainwater to the outdoor side.
