Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a bay window provided in a building.

[Prior Art] As a type of bay window that has been conventionally used, there is a front sash that is arranged outwardly from the wall so as to be almost parallel to the wall, and a connection between the front sash and the wall. Some have satsushi on both the left and right sides placed between them. In the early form of this bay window, the front sash was a sliding type, and the side sashes were a fixed type. Additionally, as housing became more Western-style and diversified, a type with a fixed front sash and a rotating side sash was developed. According to these bay windows, by sliding the front sash or rotating the side sash, either sash can be opened to ventilate the room.

[Problems to be Solved by the Invention] However, with the former bay window, even if the front sash is opened to the maximum extent, the open area is not sufficient, and effective ventilation cannot be achieved. Furthermore, since the front sash is spaced outward from the wall, even if you extend your hand from inside the room, you may not be able to reach the outer surface of the front sash, making cleaning difficult.

With the latter type of bay window, even if the side sashes are rotated significantly, the amount of air that can be taken in from the sides of the bay window is limited, and sufficient ventilation cannot be achieved. Furthermore, for the same reason as mentioned above, there was a problem in that the outer surface of the front sash was difficult to clean. An object of the present invention is to provide a bay window that not only allows effective ventilation by rotating the front sash, but also allows easy cleaning of the outer surface of the front sash.

[Means for Solving the Problems] Therefore, in order to achieve the above object, the present invention provides a front sash disposed outwardly from a wall so as to be substantially parallel to the wall; In a bay window equipped with a pair of mullions joined to the left and right edges of a front sash, and both upper and lower frames joined to both upper and lower edges of the same front sash, the front sash can be rotated into both standing positions or both upper and lower frames. The gist of the bay window is that it is installed and the pivot point of the front sash is set between the left and right ends of the upper and lower frames, or between the upper and lower ends of both frames.

[When the front sash is rotated, the rotation fulcrum is set between the left and right ends of the two-lower ryoshi, or between the upper and lower ends of the two-stand, so both can be stood up with the same rotation fulcrum as the boundary. The space surrounded by the upper and lower frames is divided into two parts and opened. Therefore, effective ventilation is performed from the space.

Furthermore, when the front sash is rotated significantly, its outer surface moves to the inside of the bay window, making it easier to reach the outer surface of the front sash from inside the room. In particular, when the front sash is rotated approximately half a turn, the entire outer surface of the front sash faces indoors, making it the easiest to reach.

``Example'' An example embodying the present invention will be described below with reference to FIGS. 1 to 4.

As shown in Fig. 2.4, the rear end of a roofing material 3 protruding forward (to the left in Fig. 2) is fixed to the upper end of the opening 2 provided in the wall 1, and the lower end of the roofing material 3 An upper frame 4 is attached to the edge. A rear end portion of a skylight 5 is rotatably attached to the roofing material 3, and by rotating the skylight 5, an opening 3a provided in the roofing material 3 can be opened and closed for ventilation. It is possible. Note that the skylight 5 incorporates glass 6 and a blind (not shown).
It is also possible to adjust the amount of daylight.

A rear end of a bottom panel 7 that projects forward while being spaced from the roof material 3 is fixed to the lower end of the opening 2, and a lower frame 8 is attached to the upper edge of the bottom panel 7. . A mounting plate 9 is attached to the bottom panel 7, on which small items etc. can be placed.

As shown in FIG. 1, a pair of molds 10 are attached to both left and right ends of the opening 2. As shown in FIG. Also, ``1 lower both frames 4
, 8 are provided with -5 pairs of left and right mullions 11. A front sash 15 having a brine inside is rotatably supported at an intermediate position between the upper and lower frames 4, 8 in the left-right direction between the two stands 11. Third
The figure shows the support structure of the lower part of the front sash 15, and a mounting bracket 16 is fixed on the lower frame 8 with screws 17. The center portion of the mounting bracket 16 is bent into a mountain shape so as to protrude in one direction. On the other hand, a mounting bracket 18 having the same shape as the mounting bracket 16 is fixed to the lower surface of the front sash 15 with screws 19 in the opposite direction. The center portion of the mounting bracket 18 is bent so as to protrude downward. And reinstallation bracket 16.18
The central protruding portion of is rotatably connected via a spacer 20 to a glue bed 21 as a rotation fulcrum. The support structure for the upper part of the front sash 15 is also the same as described above. When the front sash 15 configured in this manner is closed as shown by the solid line in FIG.
It becomes almost parallel to . Between the formwork 10 and the mullion 11, there are left and right side sashes 22 with blinds installed at intermediate positions in the left and right direction of both lower frames 4.8.
．． 23 are each rotatably supported. The support structure of these left and right side sashes 22 and 23 is the same as the support structure of the front sash 15.

In the bay window of this embodiment configured as described above, for example, by rotating the front sash 15, it is possible to
The space surrounded by 1 and the upper and lower frames 4.8 is divided into two parts and opened. At this time, a larger area is opened than in the past, allowing for sufficient ventilation.

Of course, effective ventilation can also be achieved by rotating the side sashes 22, 23.

In addition, since the glue bed 21 serving as a pivot point for the front sash 15 is arranged at an intermediate position in the left-right direction of the upper and lower frames 4.8 between the two stands 11, for example, the front sash 15 is If you turn it approximately half a turn counterclockwise as shown in , the entire outdoor glass surface faces toward the indoor side, making it easier to reach and clean the glass surface. Similarly, both left and right sides have 22
By rotating the parts 23 by a large amount, it becomes possible to easily clean the outer surfaces thereof.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and may be modified and embodied as desired without departing from the spirit of the invention, for example, as described below.
