Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding window, for example, a sliding window used as a heat insulating sash.

[0002]

2. Description of the Related Art As a conventional window sash, a sliding window type in which one or a plurality of sliding doors are slidably accommodated in a window frame is often used.

In recent years, window frames and shojis have been made of metal indoor members made of extruded aluminum members and the like, outdoor members made of similar shape members, and resin heat insulating members connecting these indoor and outdoor members. Insulation sashes made of are increasingly used. In such a heat insulating sash, even if the outdoor member is cooled by the outside air in winter, the cold heat is insulated by the heat insulating member, so that the temperature of the indoor member is maintained at approximately room temperature, and good dew-proofing property is obtained. It has become.

[0004]

By the way, since the sash forming the sash may be warped by wind pressure, conventionally, the sash which has been warped to the outside is corrected into the room or provided on the sash. In order to bring the sealing material into close contact with the window frame, a drawing member for drawing the shoji to the indoor side is arranged in the vertical frame. However, conventionally, no countermeasure has been taken for a large warp of the shoji to the indoor side.

[0005] In particular, in the case of a shroud made of a heat insulating sash, the outdoor member is cooled by the outside air and contracts, and the indoor member expands relatively to the outdoor member. It may be greatly warped to the indoor side even by contraction and expansion. Therefore, correcting the warp is an important issue.

According to experiments and the like, the warp in the heat insulating sash is the largest in the vertical direction of the shoji, especially in the central part.
In the case of ° C., the surface temperature of the outdoor member becomes −6 ° C., the surface temperature of the indoor member becomes about 8 ° C., the surface temperature difference becomes 14 ° C., and a warp of about 4 mm occurs in the central portion. Therefore,
If the surface temperature difference becomes larger, further warpage may occur, and depending on the degree of warpage, the vertical frame on the door side of the shoji interferes with part of the vertical frame that constitutes the window frame, and the shoji is surely It may not close.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sliding window in which a shoji can be securely closed even when the shoji is greatly warped to the indoor side.

[0008]

SUMMARY OF THE INVENTION A sliding window according to the present invention comprises a window frame and a shoji housed in the window frame so as to be movable in a finding direction. A sliding window provided with a protruding portion on the indoor side from a portion facing the front stile, wherein at least one of the protruding portion of the window frame and the stile on the side of the door end of the shoji, and the other And a donation means for bringing the shoji to the outside of the room while contacting the door. That is, in the present invention, the donating means may be provided only on the protrusion of the window frame, may be provided only on the vertical frame on the door-end side of the shoji, or may be provided on both the window frame and the shoji.

In the present invention, since the donating means is provided on the projection of the window frame and / or the vertical frame on the side of the door of the shoji, the shoji which is warped in the room moves in the closing direction. As a result, the warp is corrected by the donation means and the door is securely closed. At this time, by providing the donating means near the vertical portion of the projection of the window frame or the vertical frame of the shoji, large warping of the shoji can be effectively corrected.

[0010] In the above, at least the shoji of the window frame and the shoji may be constituted by an indoor member arranged on the indoor side, an outdoor member arranged on the outdoor side, and a heat insulating member connecting these indoor and outdoor members. Good. In such a case, since the shoji has a so-called heat insulating structure, a large warp of the shoji to the indoor side is corrected even in the sliding window provided with the heat insulating performance, so that the shoji can be securely closed.

In the sliding window of the present invention, the donating means may be provided on the piece member. In such a case,
In order to provide the donation means on a piece member separate from the window frame and the vertical frame, for example, by making the piece member made of synthetic resin, the window frame made of metal or the like does not directly contact the shoji, The shoji and the window frame are prevented from being damaged.

Further, such a donating means may be an inclined surface which is located on the indoor side from the vertical frame of the window frame toward the vertical frame of the shoji, and in such a case, the structure of the donating means is simple. And the donation means can be easily formed. Here, the inclined surface includes a flat surface and a curved surface such as an arc surface.

Further, in the sliding window of the present invention, when the donating means is provided on the side of the vertical frame of the shoji, a guide piece inserted between the indoor member and the outdoor member constituting the vertical frame of the shoji is provided on the vertical frame of the window frame. A drawing member is provided between the indoor member and the outdoor member of the vertical stile, and a drawing member that contacts the guide piece is arranged on the drawing member. A first inclined surface and a second inclined surface located on the indoor side of the first inclined surface and inclined in a direction opposite to the first inclined surface may be provided, and the second inclined surface may be used as a donating means.

[0014] Conventionally, in order to correct a shoji that has been warped to the outside of the room, a pulling member provided with only the first inclined surface has been provided in some cases. In the present invention, a second inclined surface which is inclined in a direction opposite to the first inclined surface is provided on the collecting member, and the second inclined surface is used as a donating means. It becomes possible to correct even if the shoji warps both inside and outside, and the number of parts can be reduced.

[0015] The outdoor surface of the guide piece may be inclined toward the indoor side at the leading end in the protruding direction. In such a case, the sash may come into contact with the inclined outdoor surface of the guide piece. As a result, the correction of the shoji that warps to the indoor side is assisted, and the shoji can be more securely closed.
