Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a folding window in which three windows are connected in the vertical direction and can be folded to open and close at this connected portion.

BACKGROUND ART Conventionally, windows have been selectively opened and closed using either a swing method or a slide method. However, even if attempts are made to improve ventilation, especially in high-rise buildings, some windows are constructed so that they do not open beyond a certain level to prevent windows from falling, but there is a problem in that sufficient ventilation cannot be achieved.

Therefore, as shown in FIGS. 4 and 5, there are two upper and lower windows 1 and 2 that are connected to each other. A center folding window has been developed in which the upper end of the upper window 1 slides down along the guide 5 of the side frame 4a of the window mounting frame 4 when the windows 1 and 2 are folded into a dogleg shape and opened. has been done.

Problems to be Solved by the Invention In this configuration, when the two windows 1 and 2 are bent into a dogleg shape and opened, a triangular opening is formed when the window is viewed from the side. However, there was a problem in that the opening size was not large enough depending on the degree of pollution of the indoor air.

This invention solves these problems,
When the window is viewed from the side, it is intended to be larger than the conventional triangular opening to improve air circulation.

Means for Solving the Problem In order to solve this problem, the present invention provides three windows vertically connected to each other by hinges within the window mounting frame of the building, and among the three windows, Either the upper end of the uppermost window or the lower end of the lowermost window is supported so as to be movable up and down with respect to the side frame within the window mounting frame, and the other is pivotally supported on the side frame of the window mounting frame. When the windows are pushed open, the side surface shape is approximately trapezoidal, and an arm or the like is installed between the side of the middle window of the three windows and the side frame of the window mounting frame. The structure is such that the three windows are held in an open state with a substantially trapezoidal side profile by interposing support means.

Effect: With this configuration, when the open window is viewed from the side, the opening has a substantially trapezoidal side profile, which is larger than the conventional triangular opening.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

First, a first embodiment shown in FIGS. 1 and 2 will be described.

In the figure, 11 to 13 are window mounting frames 14 of the building.
There are three windows installed vertically inside the window, the top window 11 and the bottom window 13 are the same size in the vertical direction, and the middle window 12 is vertically larger than the windows 11 and 13 above and below. It is formed long in the direction, and the uppermost window 1
1 lower end frame 11a and upper end frame 12 of the middle window 12
a, the lower end frame 12b of the middle window 12, and the upper end frame 13a of the lowermost window 13 are each bendably connected by a hinge 15 having a horizontal axis. Further, the upper end frame 11b of the uppermost window 11 has rollers 23 provided on both left and right sides of the side frame 4 of the window mounting frame 14.
It is configured to fit into the guide 16 of a and to be able to move up and down as well as rotate. Note that the lower end frame 13b of the lowermost window 13 is pivotally supported by the lower end of the side frame 4a of the window mounting frame 14. Reference numeral 17 denotes an arm connecting the vicinity of the upper end of the intermediate window 12 and the side frame 4a of the window mounting frame 14, and both ends of this arm 17 are pivotally supported to the side of the intermediate window 12 and the side frame 4a. ing. The height of the connection between the arm 17 and the side frame 4a is set to be lower than the connection between the middle window 12 and the arm 17 when the three windows 11 to 13 are opened, as shown in FIG. It is composed of Reference numeral 18 denotes a vertically intermediate side portion of the intermediate window 12 and the window mounting frame 1.
A damper that connects the vicinity of the lower end of the side frame 4a of No. 4,
Both ends of this damper 18 are pivoted to the intermediate window 12 and the side frame 14a. This damper 18 has a structure in which the rod 18a is biased in the protruding direction. Reference numeral 19 denotes a stopper for stopping the lowering of the upper end of the uppermost window 11 at a predetermined position, and the roller 23 is placed on this stopper 19.

In the above configuration, when the handle 20 provided at the connecting portion between the intermediate window 12 and the lowermost window 13 is pushed outward, the upper end of the uppermost window 11 descends along the guide 16. , the middle window 12 opens in parallel from the closed state. At this time damper 18
is contracted, and the intermediate window 12 is forced outwardly by the damper 18. As a result, the connecting portion between the uppermost window 11 and the middle window 12 and the connecting portion between the middle window 12 and the lowermost window 13 are bent into a dogleg shape, and the connecting portions are bent sideways as shown in FIG. Openings 21 that are approximately trapezoidal when viewed from above are formed on both sides.
At this time, since the upper end of the uppermost window 11 is lowered, an opening 22 is also formed above it. As shown in FIG. 2, the open state of the three windows 11 to 13 is held by the arm 17 and damper 18, and when closing the open windows 11 to 13, it is necessary to hold the handle 20. By pulling the damper 18, the three windows 11 to 13 can be closed while expanding the damper 18. By the way, in this embodiment, the room can be ventilated through the openings 21 formed on both sides and the opening 22 formed at the top end, and the openings 21 on both sides are larger than the conventional triangular openings, and the ventilation effect is improved. do. Further, the inner spaces of the three open windows 11 to 13 can be used to dry laundry or hang flower pots.
Further, in this embodiment, the lower end of the lowermost window 13 is configured so as not to rise or fall; however, when the lowermost window 13 is opened as shown in FIG. It is also possible to lift the lower end frame 13b of the lower window 13 to clean the outer surface of the window 13.

Next, the second embodiment shown in FIG. 3 will be described. In this second embodiment, the folding window of the first embodiment is turned upside down, and the side part near the upper end of the middle window 12 and the side frame 1 are
4a, and an arm 17 is interposed between the side near the lower end of the intermediate window 12 and the side frame 14a. In the drawings, the same reference numerals as in the first embodiment indicate the same members. ing. In this embodiment, an opening 22 is formed below the lowermost window 13.

Further, in the two embodiments described above, the sizes (lengths in the vertical direction) of the uppermost window 11 and the lowermost window 13 are the same, but they can also be made different.

Effects of the invention As described above, according to the invention, when an open window is viewed from the side, the opening has a substantially trapezoidal side profile, which is larger than the conventional triangular opening.
It is possible to improve the ventilation effect. Furthermore, the space inside the open window can be used to dry laundry or hang flower pots.
