Description

[Detailed description of the invention] In this invention, the upper horizontal frame and the lower horizontal frame of the bay window are curved so as to extend out from the window mounting opening of the building in a substantially circular arc shape in plan view, and are installed in the window mounting opening. Concerning improvements to unit bay windows.

Recently, many bay windows have been installed to improve the appearance of buildings or to make effective use of space, and in order to give these bay windows a sense of fashion, bay windows that are approximately arcuate in plan view have been proposed. It's reached.

This idea is a further development of the conventional arc-shaped bay window, which makes it possible to improve the appearance, and is easy to manufacture, which is extremely advantageous for mass production.
The purpose is to provide a structurally robust bay window.

An embodiment of this invention will be described below with reference to the drawings. In Figures 1a to 1c, 1 is the main body of the bay window, 2 is the roof frame above it, and 3 is the skylight provided in the roof frame. It is. In the vertical cross-sectional view of FIG. 2, the bay window main body 1 and the roof frame 2 are attached to a window mounting opening 5 formed in a building wall 4. The base end flange 2a of the roof frame 2 is fixed with screws 7. Further, the upper horizontal frame 6 of the bay window main body 1 is formed into an arc-shaped curved frame that extends from the window mounting opening 5 to the entire area of the outdoor side projecting edge in a substantially arc shape in plan view, as shown in the plan view of FIG. 1c. , on the tip edge of the upper horizontal frame 6,
As shown in FIG. 2, a hanging wall 6a for preventing wind and rain from entering is integrally formed, and a shallow concave gutter 6b is provided in the entire longitudinal direction of the indoor side of the hanging wall 6a. Drain hole 6 communicating with
c is drilled. As shown in FIGS. 1c and 2, a large opening 8 is formed on the upper surface of the roof frame 2 over almost the entire area, and an L-shaped opening 8 is formed along the edge of the opening 8. By forming a stepped portion 8a and fixing a transparent plate 9 such as a glass plate or a polycarbonate plate to the stepped portion 8a via an adhesive 10 or a packing 11, a skylight capable of letting in light and heat is formed. The lower horizontal frame 12 of the bay window main body 1 is curved to have the same curvature as the upper horizontal frame 6, as shown in FIG. Frame 13 and the lower horizontal frame 12
is integrally formed by casting or welding,
Attach the flange portion 13a protruding from the base of the lower frame 13 to the lower crosspiece 5b, which is the lower edge of the window mounting opening 5, with screws 1.
4, one end of the base plate 15 extending toward the indoor side is brought into contact with an edge frame portion 12a protruding from the upper surface of the lower horizontal frame 12, and screwed thereto.

Further, at both ends of the window mounting opening base of each of the upper horizontal frame 6 and lower horizontal frame 12 of the bay window, projections 16 having rectangular cross sections facing each other vertically are provided.
a, 16b, 17a, 17b, and these protrusions 16a, 16b, 17a, 17b are attached to the upper and lower ends of the left and right vertical frames 18, 19, respectively, which are hollow rectangular cylinders and are installed along the window mounting opening 5. Hollow part 18
a, 19a, and by connecting both with screws 20, 21, the upper horizontal frame 6 and lower horizontal frame 12 of the bay window and the left and right vertical frames 18, 19 are firmly connected, and the bay window The main body 1 becomes structurally robust (see FIGS. 2 and 3).

In FIG. 3, the vertical frames 18 and 19 are screwed to the vertical bars 5c and 5d, which are the left and right edges of the window mounting opening 4, and the mullion 22 provided at the center of the projecting part of the bay window main body 1 is fixed with screws. It is screwed to the upper and lower horizontal frames 6 and 12 through holes 22a and 22b, respectively.

And upper and lower horizontal frames 6, 12 and left and right vertical frames 18, 1
In this embodiment, an opening/closing door 23, which is an inner frame of the window, is attached to the bay window main body 1 consisting of a window 9 and a mullion 22, so that it can be opened and closed about a hinge section 24 at one end thereof. This opening/closing door 23 is made up of upper and lower horizontal inner frames 25, 26, left and right vertical inner frames 27, 28, and a window glass 29 fitted within these frames, like a normal door. As shown in FIG.
In order to make it easier to bend with the same curvature as 2,
It is divided into outdoor side dividing members 25a, 26a and indoor side dividing members 25a, 26b, and after bending them, they are integrated with screws 30a, 30b. Note that descriptions of well-known components in the drawings will be omitted.

As described above, according to this invention, the leading edge of the roof frame is curved to the same curvature as the upper horizontal frame of the bay window, the roof frame and the upper horizontal frame of the bay window are integrally formed, and the leading edge of the lower frame is curved to the same curvature as the lower horizontal frame of the bay window, the lower frame and the lower horizontal frame of the bay window are integrally formed, and an opening for installing a skylight is provided on the upper surface of the roof frame, and a skylight is installed in this. Because of this,
The roof frame and the upper horizontal frame of the bay window, and the lower base frame and the lower horizontal frame of the bay window are connected separately. Unlike conventional bay windows, their connecting parts or joints are not exposed, and the bay window itself and the lower frame are connected separately. While the roof frame and the lower frame can harmonize well and give a good appearance, in particular, the integral formation of the roof frame and the upper horizontal frame of the bay window, and the integral formation of the lower frame and the lower horizontal frame of the bay window, makes it easier to manufacture them. This makes it easy to mass-produce bay windows, which is very advantageous, and also allows bay windows to be assembled robustly and has the effect of improving rain protection.
Furthermore, the skylight provided on the top surface of the roof frame improves the lighting efficiency, and the arc-shaped bay window body and the skylight harmonize, making it possible to improve the appearance.

In addition, a gutter is integrally formed on the indoor side of the upper horizontal frame of the bay window, and a drain hole that communicates with the indoor and outdoor areas is provided in the gutter, so that condensed water on the lower side of the skylight can be drained from the gutter. It has the effect of being able to receive the water and discharge it outdoors.

Furthermore, according to the present invention, protrusions having rectangular cross sections facing each other in the vertical direction are provided protruding from the bases of the upper and lower horizontal frames of the bay window on the side of the window mounting opening, respectively, and these protrusions are used to attach the window to the window. The upper and lower ends of the hollow rectangular cylindrical left and right vertical frames that are installed along the installation opening are fitted and connected with screws, so the connecting parts (protrusions) of the upper and lower horizontal frames of the bay window )
The bonding contact area between the respective bonded parts (upper and lower ends of the vertical frame) of the left and right vertical frames corresponding to each bonded part is,
It is much larger than simply connecting the top and bottom ends of the left and right vertical frames to the upper and lower horizontal frames of the bay window with screws, and the upper and lower horizontal frames of the bay window and the left and right vertical frames are firmly connected and fixed. The bay window body can thereby provide a structurally robust bay window.
