Description

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

BACKGROUND ART Conventionally, windows have been 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. 6 and 7, there are two windows 1 and 2, upper and lower windows 1 and 2 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. ing.

Problems to be solved by the invention In this way, in a center-folding window in which the upper and lower windows 1 and 2 are bent in a dogleg shape to open, for example, in order to increase the lighting of the room, it is necessary to If you want to form a long window in the vertical direction across the neighborhood,
The lengths of the upper and lower windows 1 and 2 in the vertical direction both increase, and as is clear from FIG.
has become very large, and there is a problem that the amount of protrusion when the two windows 1 and 2 are opened becomes large. There is a limit to this amount of protrusion due to construction laws.
If it becomes large, there is a problem that it may protrude into the neighboring premises or, if the buildings are close together, it may hit the side of the neighboring building.

This invention solves these problems,
For example, even when a large window is formed in the vertical direction to increase daylight, the purpose is to make it possible to reduce the amount of protrusion of the window when opened.

Means for Solving the Problem In order to solve this problem, the present invention provides at least three windows vertically connected to each other by hinges within the window mounting frame of the building, and among them,
The two windows adjacent to each other are configured so that they can be bent into a dog-shaped side surface, and are configured to be movable up and down along the side frame of the window mounting frame while the other window faces vertically, and the at least A means is provided to keep the three windows open.

Effect This configuration has a better side profile compared to a structure in which the entire structure is made up of two vertically long windows connected to each other, which are bent into a dogleg shape to open the window. The windows that are bent into a dogleg shape are smaller and the amount of protrusion when opened can be reduced.

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.

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 uppermost window 11 is configured to be vertically movable along a guide 16 of the side frame 14a of the window mounting frame 14, and its downward movement is controlled by a stopper (not shown) provided on the guide 16. It is designed to be able to be stopped at a predetermined position. Note that the lower end frame 13b of the lowermost window 13 is pivotally supported by the lower end of the side frame 14a of the window mounting frame 14. Reference numeral 17 denotes a vertically intermediate side portion of the intermediate window 12 and a side frame 14 of the window mounting frame 14.
This damper 17 is a damper that connects the window 17 to the window 17a, and both ends of the damper 17 are pivotally supported to the intermediate window 12 and the side frame 14a. This damper 17 is a rod 18
is biased in the protruding direction. By the way, the window mounting frame 14 is formed vertically and vertically from near the floor of the room to near the ceiling.

In the above configuration, when the handle 19 provided at the connecting portion between the intermediate window 12 and the lowermost window 13 is pushed outward, the uppermost window 11 will be in a vertical state as shown in FIG. It descends along the guide 16, and the middle window 12 and the lowermost window 13 are folded into a dogleg shape on their sides to open. As a result, an opening 20 is formed above the uppermost window 11, and triangular openings 21 are formed on both sides of the middle window 12 and the lowermost window 13 when viewed from the side. As shown in FIG. 2, the three windows 11 to 13 are held open when the uppermost window 11 hits the stopper when it descends and is held open by the biasing force of the damper 17. Windows 11-13
When closing, by grasping and pulling the handle 19, the three windows 11 to 13 can be closed while extending the gas stay 17. In this embodiment, the opening 20 above the top window 11
The interior of the room can be ventilated through the openings 21 on both sides of the middle window 12 and the lowermost 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 upper window 11 is turned upside down.
is formed longer in the vertical direction than the other two windows 12 and 13, and the first embodiment A damper 17 similar to the above is interposed.

In the case of this second embodiment, when the handle 19 provided at the connecting part between the uppermost window 11 and the middle window 12 is pushed outward, the uppermost window 11 and the middle window 12
Triangular openings 22 are formed on both sides when viewed from the side, and an opening 23 is formed below the lowermost window 13, and these openings 22 and 23 allow ventilation of the room.

Next, referring to the third embodiment shown in FIG.
, and instead of the damper 17 provided in the first embodiment, a vertically intermediate side portion of the lowermost window 13 and a side frame 14a of the window mounting frame 14 are connected. A hanging arm 24 is interposed between them, and with this configuration, when the three windows 11 to 13 are opened, openings 25 and 26 are formed above the uppermost window 11 and below the lowermost window 13. The middle window 12 and the bottom window 1 are formed at the same time.
Triangular openings 27 are formed on both sides of 3 when viewed from the side, and these openings 25, 26, 27 can ventilate the room. The open state of the window shown in FIG. 4 is maintained by the hanging arm 24. Specifically, as shown in FIG. 4, the hanging arm 24 and the lowermost window 13 are connected so that the window is kept open.

By the way, in FIG. 5, a hanging arm 24 is interposed between the vertically intermediate side of the second window 13 from the bottom and the side frame 14a of the window mounting frame 14. As shown by the two-dot chain line in FIG. 5, a damper 17 similar to that of the first embodiment is installed between the vertically intermediate side of the second window 12 from the top and the side frame 14a of the window mounting frame 14. It is also possible to intervene. It is also possible to provide both the suspension arm 24 and the damper 17.

Effects of the invention As described above, according to the invention, a folding window is constructed of three or more windows, two of which can be folded into a dogleg shape on the side, and the other windows can be bent vertically. By being able to move up and down along the side frame of the window mounting frame while facing in the same direction, when the whole is constructed by connecting two long windows in the vertical direction to increase daylight, the side surface shape is doglegged. When the window is bent in an open position, the amount of protrusion becomes large, whereas when the window is bent in a dogleg shape, the amount of protrusion becomes smaller when the window is opened.
