Description

[Detailed Description of the Invention] This invention relates to a bay window or the like that is attached to a window opening of a building, or an arcuate bay window that is attached to a corner of a building.

Recently, bay windows such as bay windows have been installed to improve the appearance of buildings or make effective use of space, but conventional bay windows installed in this type of bay windows have a window frame structure on a straight plane. It was hot. Furthermore, recently, from the standpoint of fashionability, bay windows with a planar arc shape have been proposed.
In other words, the conventional arc-shaped bay window was
There are some methods disclosed in Publication No. 53-89730 and Publication of Utility Model Application No. 50-85031. In these bay windows, the window shoji is installed in a snap-fitting manner, or movably installed in a sliding manner, or It is designed to be installed as a hinged door.

By the way, if the window shoji of an arc-shaped overhanging window is a snap-in type, it naturally lacks ventilation and cannot promote the circulation of indoor and outdoor air. There is a difference in level between the indoor shoji and the outdoor shoji at the center of the front of the window, resulting in an unsightly appearance, and the inconvenience that only a portion of the window can be opened when opening the window. be. On the other hand, opening shoji screens do not have the above-mentioned disadvantages and are advantageous in terms of appearance and ventilation. However, in the case of conventional hinged shoji for arc-shaped overhanging windows, there is no means to lock the shoji in the required open position.
Not only was it impossible to adjust the ventilation, but the open shoji screens would rattle or close unexpectedly due to wind pressure.

The present invention has been made in view of the above circumstances, and is an arc-shaped overhang window in which the upper and lower horizontal frames of the window frame installed in the window installation opening are formed in a planar arc shape so as to overhang the outside of the room. And in the window frame above,
A pair of left and right window shojis are arranged in which the upper and lower horizontal frames of each shoji frame are formed in a planar arc shape with the same curvature as the upper and lower horizontal frames of the window frame, and the outer edges of each window shoji are connected to the left and right vertical lines of the window frame. Each is hinged to the frame so that it can be opened outward, and
The other end of a swinging lever with a guide piece attached to one end via a screw operating rod is pivotally connected to the lower end of each window sash,
The guide piece is slidably engaged with a guide groove provided along the lower horizontal frame of the window frame and located on the indoor side of the hinge part of the window shoji, and by tightening the screw operating rod. It is an object of the present invention to provide an arcuate overhang window in which a guide piece is pressed into a guide groove.

Hereinafter, one embodiment of the present invention will be explained based on the drawings. In FIG. 1 or 2, 1 is an opening for installing a window provided on the wall of a building, and 2 is an opening for installing a window in the opening 1 for installing the window. This is a bay window that is a type of bay window, and 3 and 3 are a pair of left and right window shoji that are attached to this bay window 2. 4 is an arc-shaped roof frame made of aluminum casting, etc.; 5 is also an arc-shaped lower support frame; 6
7 is the roof part at the top of the roof frame, and 7 is the lower pedestal part. 8
is the window frame that makes up the outer frame of the bay window, and 9 is this window frame 8
This is the shoji frame of each window shoji 3 that is fitted into the window shoji 3. The window frame 8 installed in the window installation opening 1 consists of upper and lower horizontal frames 8a, 8a and left and right vertical frames 8b, 8b as before.
The shoji frame 9 of each window shoji 3 consists of upper and lower horizontal frames 9a, 9a and left and right vertical frames 9b, 9b, and a window glass 10 is appropriately mounted within the shoji frame 9 framed by these. It is.

Then, the upper and lower horizontal frames 8a, 8a and the left and right vertical frames 8
The upper and lower horizontal frames 8 of the window frame that is the outer frame consisting of b and 8b
As shown in FIG. 4, a and 8a are curved frames bent into planar arc shapes that extend outward from the room, and the upper and lower horizontal frames 9a and 9a of the shoji frame 9 are also the same as the upper and lower horizontal frames 8a and 8a of the window frame 8, respectively. It is curved to the same curvature as 8a.

Note that reference numeral 11 denotes a normal hinge, which is attached between each vertical frame 8b of the window frame 8 and the vertical frame 9b on the outside of the shoji frame 9.

In FIGS. 3 and 4, reference numeral 12 denotes a swing lever. A rectangular guide piece 15 is attached to one end of this lever via a screw operating rod 13, and the other end of the swing lever 12 is 3 and 4 of the lower end of the shoji frame 9
It is pivoted in the position shown in the figure. The guide piece 15 is a bolt portion 13a at the lower end of the screw operating rod 13 attached to one end of the swing lever 12.
and a guide groove 14 formed along the indoor side edge of the lower horizontal frame 8a of the window frame 8 (this guide groove 14 is located closer to the indoor side than the hinge 11 attachment part). Slidably engaged. Therefore, during operation, by tightening the screw operating rod 13, the guide piece 15 screwed with the bolt portion 13a moves downward or upward, and the bottom wall portion of the guide groove 14 is moved downwardly or upwardly. Alternatively, it is crimped and fixed to the upper wall, so that the window sash 3 can be locked in the closed position and any open position via the swing lever 12.

Figure 5 shows another embodiment of this invention.
In this embodiment, a planar arc-shaped window mounting opening 1 is provided at a corner of a building, into which an arc-shaped overhang window having the same structure as described above can be mounted. In FIG. 5, the same components as those in the embodiment described above are given the same reference numerals, and their explanations are omitted.

As explained above, according to the arc-shaped overhang window of the present invention, since the window shoji consists of a pair of window shoji that open outward on the left and right sides, the window opening can be completely opened and sufficient ventilation can be achieved. In addition, when the window is closed, there is no step at the center of the front of the window, unlike the sliding type, which gives it a good appearance.In particular, according to the present invention, each window shoji can be locked in any open position. This allows ventilation to be adjusted and eliminates the inconvenience of open window shoji rattling due to wind pressure or closing unexpectedly.
