Description

[Detailed description of the invention] [Industrial application field] This invention relates to bay windows for buildings such as general wooden houses and non-wooden housing complexes.

[Conventional technology]

Conventional bay windows of this type, for example, have a curved bay window with a fitted window in the center, and single-sliding windows on the left and right sides, with storm shutters stored in left and right door pockets installed in the wall. There is a type. Other examples include pentahedral structures, with a window in the center, a sliding window on the left and right sides, and a window in the sleeves on both sleeves, and some do not have shutters.

[Problem that the invention attempts to solve]

However, these bay windows had the following problems due to their construction.

(1) Since the area of opening/closing windows such as single sliding windows or vertical sliding windows is relatively small compared to the opening area of the wall, ventilation efficiency above a certain level cannot be expected even if these windows are fully opened. Furthermore, since the operable window is vertically long and its width is generally narrow, even when fully opened, it is difficult for outside air to flow in at a wide angle in the horizontal direction, making it impossible to enjoy the cool air throughout the room.

(2) The window frames of lattice windows, single sliding windows, vertical sliding windows, etc. run vertically across the opening in the wall, or the lattice-shaped glass frame of each window runs across the window frame. can't be said to have a good view from inside the room. The appearance may also be undesirable depending on the design of the building.

(3) Since storm doors are generally not installed, they are left unprotected during storms, which is not good for security. Of course, some houses have storm doors, but it is common to have a special door pocket along the wall.
It is complicated to fit, and construction is time-consuming and costly. Not only that, but the process of putting in and taking out the shutters itself is not functional.

This idea was made to solve these conventional problems; (1) it has good ventilation efficiency;
(2) Outside air can be introduced into the room from a wide angle; (3)
The purpose is to provide inexpensive and functional shutters and (4) bay windows with excellent views and exterior appearance.

[Means for solving problems]

The bay window according to this invention has a window frame formed by left and right vertical frames and upper and lower horizontal frames that are convex to the outside, a waist wall fixed to the lower part of the window frame, and a wall outside the waist wall. a movable glass shoji made of full glass that is attached to the window frame so as to be movable up and down and opens and closes an opening formed by the window frame and the waist wall; and an outside of the movable glass shoji and the window frame. It is equipped with a shutter that is movable up and down.

[Effect]

(1) Since the opening formed by the window frame and waist wall is opened and closed with a movable glass shoji made of a single sheet of glass,
When fully opened, all of the openings are opened, and these openings are not blocked by the shoji. Therefore, compared to conventional methods where only a portion of the opening in the wall is opened,
Improves ventilation efficiency.

(2) Also, by opening the movable glass shoji, the upper opening can be opened across the entire width, so
Outside air can be brought into the room from a wide angle, allowing you to enjoy the cool feeling throughout the room.

(3) The shutters can be stored on the outside of the waist wall as a "waist wall" in appearance, and during rainstorms, they can literally be used as shutters.
Since it can be used as a security door at night, it is preferable for security reasons, and unlike conventional ones, it does not require a door pocket and is easy to operate, so it is inexpensive and functional.

(4) Movable glass shoji is made entirely of glass, and does not have a structure in which glass is fitted into a window frame or lattice frame as in the past, so there is no obstruction to the view, improving the view from inside the room, and improving the exterior appearance. This may also be desirable depending on the design of the building.
