Description

The present invention relates to a picture frame that constitutes a picture frame placed on the indoor side of an opening frame such as a window frame or a door frame, and a natural wind ventilation window in which the opening degree of a window shoji can be adjusted by natural wind.

Conventionally, window devices have been provided at openings of building frames for the purpose of daylighting, ventilation, and the like. Further, it is common practice to provide a picture frame on the indoor side of the window frame that constitutes the window device as a parting material for the inner wall. The picture frame is composed of a plurality of picture frames respectively arranged on the indoor side of the frame material that constitutes the window frame.
In addition, the frame that constitutes the lower side of the picture frame is sometimes called a plate to distinguish it from the frame that constitutes the upper side of the picture frame, but in the present specification and claims, these are not distinguished , are all called picture frames.

The picture frame is fixed to a frame material such as an upper frame that constitutes the window frame. As a mounting structure of the frame to the frame material, for example, as described in Patent Document 1, the outdoor end of the frame is screwed to a fin-shaped angle provided at the indoor end of the frame. Fixed structures are widely used.

However, the mounting structure of the picture frame as described above needs to be screwed from the indoor space side. For this reason, if sufficient work space can be secured on the indoor side of the frame material, there is no problem, but as in the case of natural wind ventilation windows, for example, the frame is fixed with a shoji with a large expected size built inside the window frame. If it must be done, it is difficult to secure a sufficient work space on the indoor side of the frame material, and there is a possibility that the screwing work itself cannot be performed. The estimated size of the shoji means the size of the shoji in the indoor/outdoor direction.

As a mounting structure of the picture frame to the frame material, in addition to the structure using the screw described above, a structure in which the outdoor end of the picture frame is fitted to the indoor end of the frame is also known. Specifically, the frame is fitted to the frame member by pushing the fitting portion provided at the outdoor end portion of the frame toward the fitting portion provided at the indoor end portion of the frame member. To support. According to such a frame mounting structure, the frame mounting work is completed only by pushing the frame in. Therefore, even when it is difficult to secure a sufficient work space on the indoor side of the frame material, the frame can be mounted. It is possible to prevent work from becoming impossible.

However, even if a mounting structure in which the frame is fitted and supported by the frame material is adopted, if a shoji with a large projected size is built inside the window frame, the projected size of the frame should be adjusted according to the projected size of the shoji. need to be bigger. For this reason, it becomes difficult to smoothly fit the fitting portion of the frame to the fitting portion of the frame material, and problems such as deformation of the frame into an arcuate cross-section due to the pushing force toward the outside tend to occur. As described above, even when a structure in which the frame is fitted to and supported by the frame material is employed, if the estimated size of the frame becomes large, the problem arises that the workability of attaching the frame is reduced. In addition, when a frame with a large estimated size is used, the size of the extrusion die for manufacturing the frame is also increased.

[Support structure and opening/closing structure of glass shoji 5]
The glass shoji 5 is rotatably supported with respect to the window frame 4 by a pair of bearing devices (not shown). The pair of bearing devices are spaced apart in the in-plane direction and positioned above the central portion of the glass shoji 5 in the vertical direction. A pair of bearing devices is arranged between a vertical frame 9 forming the window frame 4 and a vertical frame 16 forming the glass shoji 5 . Each bearing device is supported by a vertical frame 16 and is supported by a shaft portion (not shown) disposed in the in-plane direction, and by a vertical frame 9 (outdoor vertical frame 9a), which rotatably supports the shaft portion. It is constructed with no bearings. Therefore, the natural wind ventilation window 1 of this example is a laterally rotating window that rotates around the central axis X of the shaft portion.

A balance weight 24 is fixed to the indoor side of the upper frame 14 constituting the glass shoji 5. - 特許庁The balance weight 24 is positioned above the central axis X and is attached to the upper frame 14 so as to protrude greatly toward the indoor side. The balance weight 24 includes a case 25 having a substantially U-shaped cross section fixed to the indoor side of the upper rail 14 and a weight body (not shown) arranged inside the case 25 .

Since the glass shoji 5 of this example has the balance weight 24 as described above, the position of the center of gravity is located on the indoor side of the glass panel 13 . For this reason, the glass shoji 5 is arranged at a predetermined angle (for example, about 20 to 45 degrees, preferably about 20 to 45 degrees, preferably is tilted by 30 degrees). Therefore, the air warmed in the room can be exhausted to the outside by gravity ventilation.

In addition, since the surface area of the glass shoji 5 is larger in the lower portion than in the upper portion across the central axis X, when the wind blows toward the glass shoji 5, the glass shoji 5 is The portion below the central axis X receives more wind than the portion above X.

Therefore, when the wind blows from the inside of the building to the outside, i.e., the so-called negative pressure wind, the glass shoji 5 is kept open, and is opened depending on the strength of the wind (magnitude of the wind force). change the degree. That is, if the strength of the wind increases, the degree of opening is increased, and if the strength of the wind weakens, the degree of opening is decreased.

On the other hand, when the wind blows from the outside of the building toward the interior, that is, when the wind is so-called positive pressure, the glass shoji 5 tilts to close, and the degree of opening changes depending on the strength of the wind (magnitude of the wind force). Let That is, if the strength of the wind increases, the degree of opening is decreased, and if the strength of the wind weakens, the degree of opening is increased.

The natural wind ventilation window 1 of this example has a mode in which the opening degree of the glass shoji 5 can be adjusted freely by the natural wind as described above, a mode in which the glass shoji 5 is forcibly opened in the event of a fire, etc., and a mode in which the wind strength is increased. Regardless, it is possible to switch between the mode in which the glass shoji 5 is forcibly closed. Mode switching is performed by swinging the swing pin 26 attached to the indoor-side end of the vertical frame 16 and the swing pin 26 arranged inside the cover 9c attached to the indoor-side vertical frame 9b. This is realized by electrically or manually switching the posture (inclined state) of the glass shoji 5 using the push/pull member 27, a wire or a pulley (not shown), or the like. Various modes of the natural wind ventilation window 1 and a specific structure for switching the modes are described in detail in Patent Document 2, for example, and are not the gist of the present invention, so detailed description thereof is omitted here. do.
