Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a window sash formed by attaching a folding shoji to a window opening.

(Prior art) Window sashes differ in the opening and closing operations of their shoji parts, such as those that move horizontally such as single sliding windows and double sliding windows, and those that move horizontally such as vertically rotating windows and casement windows. There are some types of shoji that rotate with the fulcrum as a fulcrum, some that rotate on a horizontal axis such as an inward-folding window, and some that rotate on a horizontal axis as a fulcrum, such as a sliding window. It is usually classified as something that rotates as a fulcrum.

In addition to the above-mentioned sashes, there are also known shojis in which the shoji part performs a folding action (for example, the
61962, JP-A-57-108383). These window sashes connect multiple shojis at their adjacent edges in a foldable manner, and these shojis are folded and stored within the expected width of the sash frame. The shoji on the indoor side is provided so that its free end can be moved along the guide rails of the upper and lower frames. In a window sash equipped with this type of folding shoji, the outdoor shoji rotates around its pivot point, and the indoor shoji rotates accordingly, while its free end is connected to the guide rail. The shoji move along the shoji, and both shojis protrude toward the outside of the room while taking an overlapping state or a spread-leg state.

(Problem to be solved by the invention) The above-mentioned conventional window sash equipped with a folding shoji has a sash on the indoor side when closed, in the former, that is, the one disclosed in JP-A-52-61962, and in the latter, in JP-A-57
- Since the central shoji of Publication No. 108383 rotates greatly, the rotation locus of these free ends must be large, and as a result,
In the case of the Utility Model Application Publication No. 52-61962, the rotating support member called a support is also
In the case of Publication No. 108383, there was an inconvenience that the guide rails called arcuate guide grooves protruded far beyond the expected width of the sash frame.

However, in Japanese Utility Model Application Publication No. 52-61962, when the shoji is closed, both the shoji are overlapped inside and outside the room, and in JP-A-57-108383, when the shoji is closed, each shoji is located in a straight line. However, the appearance of the shoji when it is closed is different.

The present invention aims to improve this type of window sash in which both the shoji are overlapped indoors and outdoors when the sash is closed, and the guide rail is made to fit within the expected width of the sash frame.

(Means for Solving the Problem) In order to achieve the above object, the present invention employs the following technical means. That is, for convenience of explanation, the present invention is described with the symbols used in the examples.
Edge 1 that adjoins shoji 1 on the outdoor side and 2 on the indoor side
These shoji 1 and 2 are foldably connected at 1 and 21, and folded and stored by overlapping each other within the expected width of the sash frame 3, and the outdoor shoji 1 has its free end 12 connected to the upper and lower frames 31, 32, and the indoor side shoji 2 has its free end 2
2 is movable along upper and lower guide rails 33, 34, and the guide rails 33, 34 are arranged above and below the storage position of the shoji 1 on the outdoor side when the shoji 1 is folded and stored. Straight rails 33a and 34a are located, and arcuate curved rails 33b and 34b each having one end continuous with the straight rails are curved toward the indoor side around the end 12 of the shoji 1. The other end of the curved rail is positioned on the indoor side of the end portion 12 within the expected width of the sash frame.

(Function) Since the window sash of the present invention is constructed as described above, first, when the indoor/outside shoji 1 and 2 are closed, both shojis are folded and stored in an overlapping manner,
At this time, the free end portion 22 of the shoji 2 on the indoor side is located at the other end of the curved rails 33b, 34b.
When the adjacent edges 11 and 21 of the shoji 1 and 2 are pushed open toward the outdoor side, the shoji 1 on the outdoor side rotates about its free end 12, while the shoji 2 on the indoor side rotates. While following this, the free end 22
The curved rails 33b and 34b are connected to the straight rail 33.
a, moving towards 34a. In the position where both the shoji 1 and 2 are perpendicular to the sash frame (building frame) (first open position), the free end 22 of the shoji 2 is located exactly at the joint between the straight rail and the curved rail. When the free end portion 22 is pushed toward the opposite side of the sash frame, the shoji 1, 2 assumes a protruding form facing toward the outdoor side in an open state (second open position).
Then, the shoji 1 and 2 are folded and stored by the operation opposite to the above. At this time, the folded and stored shoji 1 and 2 are located within the expected width of the sash frame, and similarly, the curved rails 33b and 34b are located within the expected width of the sash frame.

(Example) The window sash of the present invention will be explained below based on the illustrated embodiments.

As shown in FIGS. 1 to 4, the window sash of the present invention connects an outdoor shoji 1 and an indoor shoji 2 at adjacent edges 11 and 21 in a foldable manner. The basic configuration is that 1 and 2 are folded and stored within the expected width of the sash frame 3. The connection between the shoji 1 and 2 is the edge 1
1 and 21, in this example, a hinge 4 is interposed between opposing locations.

The shoji 1 on the outdoor side has its free end 12 pivoted to upper and lower frames 31 and 32. In other words, shoji 1 is
It can be rotated to open and close using its end 12, that is, the end on the pivoting side, as a fulcrum. On the other hand, the shoji 2 on the indoor side has its free end 22 connected to the upper and lower frames 31 and 3.
It is provided so as to be movable along two guide rails 33 and 34. In this example, the guide rails 33 and 34 are formed in grooves, and protrusions 23 and 24 that fit into the grooves are provided at the upper and lower ends of the vertical stile at the free end.

The guide rails 33 and 34 are straight rails 33
a, 34a, and curved rails 33b, 34b that follow these, respectively. The straight rails 33a and 34a are formed to correspond to the storage position of the shoji 1 on the outdoor side when it is folded and stored,
On the other hand, the curved rails 33b and 34b are curved in an arc shape toward the indoor side around the end 12 to which the shoji 1 is pivoted. In this example, the auxiliary frame 35 is used to form a curved rail.

Note that the other end of an arm 5, one end of which is pivotally connected to the lower frame 32, is connected to the shoji 2 on the indoor side. In this connection, the other end of the arm 5 is fitted into a guide groove 25 formed in the shoji 2, and by appropriately selecting the fitting position, the opening angle of the shoji 1 and 2 can be set arbitrarily. can. Further, 6 is a lock, which fixes the shoji 1 and 2 when closed. 7 is a retractable screen door.

Next, to explain the operation of the window sash of the present invention, in FIG. 1, the lock 6 is released and the shoji 2 on the indoor side is pushed toward the outdoor direction. Then, the shoji 1 on the outdoor side rotates using the end 12 as a fulcrum, and the shoji 2 rotates accordingly, and its free end 22 runs on the curved rails 33b and 34b (Fig. 3). ). Furthermore, the free end 22 of the shoji 2
By moving the shoji 1 and 2 to the left in the figure, the shoji 1 and 2 can be opened into a protruding configuration as shown in FIG. In addition, in the present invention, by adding another set of two-panel shoji, a so-called double-folding window sash can be obtained.

(Effect of the invention) The window sash of the invention is constructed as described above,
The entire inner and outer shoji 1 and 2 rotate to open and close like a casement window, and the indoor shoji 2 opens and closes to the upper and lower frames 3.
1 and 32, it is possible to obtain a window sash in which the shoji part performs a folding operation. Furthermore, the present invention provides guide rails 33, 3.
4, the straight rails 33a and 34a are located above and below the storage position of the shoji 1 on the outdoor side, and the curved rails 33b and 34b are continuous with the straight rails and located at the end of the shoji 1 on the outdoor side. The curved rail is curved in an arc shape toward the indoor side with 12 as the center, and the other end of the curved rail is located on the indoor side of the end 12 within the expected width of the sash frame. When the outer shoji 1 and 2 are stored in the sash frame, they are folded parallel to each other indoors and outdoors, and the guide rails 33 and 34 are placed at positions corresponding to the vertical direction of these shojis. Therefore, since the indoor/outside shoji and guide rails of the window sash are housed within the sash frame, the guide rails do not protrude from the sash frame as in the past, making it possible to obtain a compact window sash. It is something.
