BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing window in which a shoji is attached to a window frame such as an inward-turning window, an outward-turning window, an inward-opening window, an outward-opening window so as to be openable / closable.

[0002]

2. Description of the Related Art Various inclining windows are known in which a lower frame forming a window frame is connected to a lower frame forming a shoji so that the lower frame can swing in the indoor and outdoor directions. For example, Japanese Patent No. 2743244 discloses the above-mentioned inversion window. The inclining window described above is opened by swinging the shoji in the closed state toward the inside of the room and tilting it to the inside, and then swinging the shoji in the open state outside the room into the window frame. The stored state brings the above-mentioned closed state.

[0003]

The inward-folding window described above is a window that mainly circulates air between the inside and outside of the room, that is, ventilates the room. Most of the air circulation point (that is, the ventilation point) when the inclining window is opened is between the upper part of the shoji (upper frame) and the upper part of the window frame (upper frame). Therefore, when ventilating the room, the air supply (the air outside the room flows into the room) and the exhaust air (the air inside the room flows out) are located at one place between the upper part of the shoji screen and the upper part of the window frame. Ventilation efficiency is poor because it is performed.

It is an object of the present invention to provide an opening / closing window which can efficiently ventilate a room with two ventilation areas.

[0005]

A first aspect of the present invention is provided with a window frame in which frame members are connected in a square shape and a shoji screen in which a frame is connected in a square shape, and any one of the shoji screens is connected to the window frame. An opening / closing window that is swingably connected to any one of the frame members in the indoor / outdoor direction, and has a shoji screen housed in a window frame and in an open state in which the shoji screen is tilted toward the indoor side or the outdoor side. An opening / closing window characterized in that a ventilation part is formed on the outer side in the in-plane direction with respect to the airtight / watertight part of a frame other than the frame that forms the main ventilation part with the frame material of the window frame when opened. Is.

A second aspect of the present invention is an opening / closing window in which a ventilation portion is formed more outward in the in-plane direction than the airtight / watertight portion of the frame connected to the window frame in the first invention.

In a third aspect of the invention, in the first or second aspect of the invention, a plurality of slit-shaped openings are formed in the longitudinal direction at a position closer to the outer side in the in-plane direction than the air-tight / water-tight portion of the frame. It is an opening and closing window as a part.

[0008]

[Operation] According to the first aspect of the invention, when the shoji screen is in an open state, air flows through the main ventilation areas to the inside and outside of the room, and at the same time, the air flows to the inside and outside of the room through the ventilation section formed in the frame. Therefore, there are two ventilation points. Therefore, the room can be efficiently ventilated. Further, when the shoji screen is closed, air does not flow between the room and the room through the ventilation part formed in the frame, and rainwater or the like does not enter the room.

According to the second aspect of the present invention, the ventilation part is formed in the frame connected to the window frame, so that the ventilation part by the ventilation part of the frame and the main ventilation part face each other in the vertical direction or the left-right direction of the window frame. Therefore, the room can be ventilated more efficiently.

According to the third aspect of the invention, the plurality of slit-shaped openings are visually observed when viewed from the inside of the room, and the ventilation can be visually appealed to the user.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a sash frame 1
Then, the sliding door sash 2 with the ventilation small window is formed by the inner sliding door 2 and the outer sliding door 3 which are attached to the sash frame 1 in a sliding manner and the small ventilation window 4 attached to the inner sliding door 2. Then, by opening the small ventilation window 4 with the inner door 2 and the outer door 3 closed, the room communicates with the outdoors, and the room can be ventilated.

In the sash frame 1, an upper frame 1a, a lower frame 1b and left and right vertical frames 1c are connected in a rectangular shape. The internal shoji 2
Is an upper frame 2a, a lower frame 2b, a combination frame 2c, and a door stop frame 2d.
To form a frame assembly 7 having an upper opening 5 and a lower opening 6 by connecting the middle bands 2e across the lower part of the summing frame 2c and the lower part of the door stop frame 2d. A glass 8 is attached to the upper opening 5, and a small window 4 for ventilation is attached to the lower opening 6. The outer shoji 3 includes an upper frame 3a, a lower frame 3b, an assembling frame 3c, and a door stop frame 3
A glass 8 is attached to a frame assembly 7 in which d is connected in a square shape.

As shown in FIGS. 2 and 3, the small window 4 for ventilation is a window in which a shoji 4b is attached to the window frame 4a so as to be openable and closable, for example, the shoji 4b can be swung in the indoor and outdoor directions. The sliding door 4b is an inward tilting window attached so that the sliding door 4b can be tilted inward. A screen door 4c is attached to the outside of the window frame 4a.

Next, an example of a specific shape of the inclining window will be described. As shown in FIGS. 2 and 3, the window frame 4a is formed by connecting an upper horizontal frame member 10, a lower horizontal frame member 11, and left and right vertical frame members 12 in a rectangular shape. The shoji screen 4b has an upper frame 13, a lower frame 14, and left and right vertical frames 15 connected in a rectangular shape, and a glass 16 is attached to the inside thereof. A lower frame 14 is connected to the lower horizontal frame member 11 so as to be swingable in the indoor and outdoor directions. For example, the lower horizontal frame member 11
The shoji attachment piece 17 integrally provided at the upper end of the indoor side vertical plate 11a is fitted and connected with the arcuate concave portion 18 integrally provided at the lower end of the indoor side vertical plate 14a of the lower frame 14.

When the shoji screen 4b is swung to the indoor side and is tilted to the indoor side as shown by a phantom line in FIG. In this open state, a space between the upper portion of the shoji 4b (upper frame 13) and the upper portion of the window frame 4a (upper horizontal frame member 10) is opened, and that portion serves as a main ventilation area. Lower frame 1 of shoji 4b
4 and the lower horizontal frame member 11 of the window frame 4a are swingably connected, so that air hardly circulates between the lower frame 14 and the lower horizontal frame member 11 of the window frame 4a. The connecting part does not become a ventilation part. That is, the upper part on the side opposite to the swingable connecting part is the ventilation part.

A closed state is obtained by swinging the shoji screen 4b tilted toward the indoor side shown by phantom lines in FIG. 2 toward the outdoor side and being housed in the window frame 4a shown by solid lines in FIG. Becomes

The upper frame 13 and the left and right vertical frames 15 are the frame body 1
3a and 15a, and outward plates 13b and 15b integrally provided on the indoor side of the frame main bodies 13a and 15a. The outward plates 13b and 15b project outward in the in-plane direction from the outer surface (outer surface in the in-plane direction) of the frame main bodies 13a and 15a. When the shoji screen 4b is in the above-mentioned closed state, the outdoor side surface of each of the outward plates 13b and 15b is crimped to the upper horizontal airtight member 19 and the vertical airtight member 20 attached to the upper horizontal frame member 10 and the left and right vertical frame members 12, respectively. The lower horizontal airtight member 21 attached to the lower horizontal frame member 11
Is crimped to the outdoor side surface of the indoor vertical plate 11a of the lower frame 14.

The upper lateral airtight member 19 is provided with an airtight member mounting portion formed on the inner side of the inner surface (inner surface in the in-plane direction) of the upper horizontal frame member 10, for example, in the groove 10a which is open to the inner side of the chamber. It is attached to the inside. The vertical airtight material 20 is an airtight material mounting portion formed on the inner surface of the vertical frame member 12 on the indoor side,
For example, the groove 12a that is open to the inside of the room is mounted toward the inside of the room. The lower horizontal airtight member 21 is mounted on the inner side of the lower horizontal frame member 11 on the inner side of the lower middle inward piece 22 such as an airtight member mounting portion, for example, a recessed groove 22a opening to the indoor side facing the indoor side. I am doing it. Each of the airtight members is continuous for four rounds as shown by a dotted line in FIG. 1, and airtightly and watertightly connects between the window frame 4a and the shoji 4b.

A part other than the frame which becomes a ventilation part when the shoji screen 4b is opened, preferably a part of the frame which is swingably connected to press the airtight material (that is, airtight / watertight part).
A ventilation part is formed on the outer side in the in-plane direction. For example,
Slit-shaped openings 30 are provided in the longitudinal direction at a position closer to the outer side in the in-plane direction than the portion of the lower frame 14 other than the upper frame 13 that serves as a ventilation location where the lower horizontal airtight member 21 of the indoor vertical plate 14a is in pressure contact. Form a plurality.

By doing so, the lower lateral airtight member 21 is opened when the shoji screen 4b is opened as shown by the phantom line in FIG.
Is separated from the indoor side vertical plate 14a of the lower frame 14, and the plurality of openings 3
Air circulates inside and outside through 0. Therefore, the main ventilation area is between the upper part of the shoji screen 4b and the upper part of the window frame 4a, and the opening 30 of the lower frame 14 serves as an auxiliary ventilation area, so that there are two ventilation areas. It is possible to efficiently ventilate the room by supplying air to the ventilation area of and supplying exhaust air to the other ventilation area. In particular, by forming the ventilation portions at the upper and lower portions as described above, it is possible to ventilate the room more efficiently.

When the shoji screen 4b is in the closed state, the lower horizontal airtight member 21 is brought into pressure contact with the outdoor side surface inward of the opening 30 in the indoor vertical plate 14a of the lower frame 14 to be airtight and watertight. Air does not flow through the opening 30 into the room and the outdoors. In other words, the longitudinal end surface of the lower middle inward piece 22 of the lower horizontal frame member 11 abuts the inner surface of the vertical frame member 12, and the groove groove 22 a is formed in the groove groove 1 of the vertical frame member 12.
Since the air does not flow to the inside and the outside of the room, which is continuous with 2a and has the lower middle inward piece 22 as a boundary, the air does not flow to the inside and the outside through the opening 30.

The above-mentioned opening 30, that is, the ventilation part, has a vertical frame 1.
5 may be formed. Further, even in the case of an inclining window in which the lower frame 14 and the lower horizontal frame member 11 are connected by a hinge so as to be swingable in the outdoor direction, the interior can be efficiently ventilated by forming the opening 30 as described above.

Further, in the case of an inner opening window in which a vertical frame member and a vertical frame are swingably connected to each other in the indoor and outdoor directions by a hinge or the like, and in the case of an outside opening window, the vertical frame on the opposite side to the vertically swinging vertical frame is connected. The opening may be formed in the frame, the upper frame, or the lower frame.

Further, the upper frame 13, the lower frame 14, the left and right vertical frames 1
5 is attached with an airtight material, and the airtight material is pressed against the upper horizontal frame member 10, the lower horizontal frame member 11, and the vertical frame member 12 of the window frame 4a to hermetically and watertightly seal between the window frame 4a and the shoji 4b. May be.

Further, the window is not limited to the small window for ventilation, and a normal inclining window may be used.

[0026]

According to the first aspect of the present invention, when the shoji screen is opened, the air flows to the inside and outside of the room through the main ventilation areas, and the inside and outside of the room through the ventilation part formed in the frame. Since air circulates, there are two ventilation points. Therefore, the room can be efficiently ventilated. Further, when the shoji screen is closed, air does not flow between the room and the room through the ventilation part formed in the frame, and rainwater or the like does not enter the room.

According to the second aspect of the present invention, the ventilation part is formed in the frame connected to the window frame, so that the ventilation part by the ventilation part of the frame and the main ventilation part are in the vertical direction or the left-right direction of the window frame. Since they face each other, the room can be ventilated more efficiently.

According to the third aspect of the invention, a plurality of slit-shaped openings are visually observed when viewed from the inside of the room, so that ventilation can be visually appealed to the user.
