Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a bay window for a building using a bay window sash having a trapezoidal bay window portion projecting in the center.

BACKGROUND ART When installing a bay window in a building, it is common to install bay window sashes produced in a factory in a predetermined position.

This bay window sash is made by connecting sleeves that fit into the other spaces of the window opening to both ends of the bay window that protrudes from the center of the window opening on the outside wall of the building. A pair of upper and lower support frames protruding outward in a trapezoidal shape toward the outside of the room are assembled in the center of the window, and mounting pieces protruding from the upper and lower frames of the bay window are screwed to the outer circumferential surface of the support frames. Mounting pieces protruding from the upper and lower frames are screwed to the building frame such as pillars, lintels, and window sills. Conventionally, the support frame was formed and framed to closely match the inner circumferential dimensions of the bay window sash, so that each mounting piece would be in close contact with the support frame or building frame due to the necessity of screwing.

Problems to be Solved by the Invention The structure of the bay window sash is such that a connecting member having a generally fan-shaped cross section is incorporated between the front body of the bay window, the slope bodies on both sides of the bay window, and the slope body and the sleeves. It is secured with screws through it. However, because the connecting members are extruded, the cross-sectional shape is not necessarily uniform, and due to dimensional errors between the connecting members and the vertical frame, and the strength of the tightening force of the screws, there are some differences in the way the bay window sash is assembled. It is inevitable that variations will occur. Therefore, even if the framework of the support frame is accurate, a gap is likely to form between the sleeve mounting piece and the building frame, and this gap makes it difficult to tighten the screws when attaching the bay window sash to the building. Not only does this cause an obstruction, but even if a complementary member is inserted between them, the position of the sleeve portion shifts outward by the amount of the gap, resulting in an unsightly installation of the bay window sash.

Means for Solving the Problems This invention was made in view of the above circumstances, and it is possible to attach the sleeve mounting piece to the outside of the building frame even if there are variations in dimensions and angles of the assembled bay window sash. The purpose is to ensure that it adheres tightly to the side surface and can be attached with screws, nails, etc.

That is, in order to solve the above-mentioned problems, this invention constructs a bay window sash by connecting sleeves that fit into other spaces of the window opening to both ends of a bay window that projects into the center of the window opening on the outside wall of the building. A pair of trapezoidal upper and lower support frames sandwiching the bay window part of the bay window sash is installed in the center of the window opening, and a mounting piece that is fixed to the outer peripheral surface of the support frame is attached to the upper and lower frames of the bay window part. In addition, the end vertical frames and upper and lower frames of both sleeves are provided with mounting pieces protruding from each other that are fixed to the outside surface of the building frame around the window opening.
By forming the outer circumferential surfaces of the upper and lower support frames to be slightly smaller than the specified position where they are joined to the bay window mounting pieces, the mounting pieces on both sleeves can be directly attached to the building frame, and the bay window mounting pieces can be attached directly to the building frame. The bay window sash is attached by sandwiching a complementary member in the gap created between the window and the support frame.

Function When installing a bay window sash, insert the bay window part of the sash between a pair of supporting frames that project above and below the window opening. Since it is formed slightly smaller than the specified position where it joins the mounting piece, the mounting piece will not hit the outer circumferential surface of the support frame, while the mounting piece on the sleeve will always be in close contact with the outer surface of the building frame. , it is possible to reliably prevent displacement of the sleeve portion, which is easily noticeable when viewed from the room. In addition, a complementary member is inserted between the bay window mounting piece and the support frame, so
The mounting piece can be stably fixed to the support frame with screws, nails, etc.

Example Examples will be described below with reference to the drawings.

A bay window is formed by attaching a bay window sash S to a pair of upper and lower support frames T and T (Fig. 5).

The bay window sash S is made up of a trapezoidal bay window A and sleeves 5, 5 at both ends thereof.The upper and lower support frames T, T that sandwich the bay window A are each composed of a front member 24 made of wood and slopes on both sides. It is framed in a trapezoidal shape by members 25, 25, and a support arm 26 is diagonally interposed between it and the building outer wall 1 (FIGS. 5 and 6).
Then, the bay window portion A of the bay window sash S and the support frames T, T are made to protrude from the center of the window opening 2 of the building exterior wall 1,
Sleeves 5, 5 are fitted at both ends (FIGS. 1 to 3). Further, a top plate 28 is fitted to the upper end of the bay window portion A, and a plate plate 29 is fitted to the lower end thereof (FIG. 2).

The bay window section A of the bay window sash S is composed of a front body 3 and slope bodies 4 on both sides, and a sleeve section 5 is combined with the slope body 4 (FIG. 5). Front body 3,
The slope body 4 and the sleeve part 5 each have a plate glass 33 tightly fitted into the frame (Fig. 1),
Regarding the combination of the front body 3 and the slope body 4, and the slope body 4 and the sleeve part 5, connecting members 6, 7 having a substantially fan-shaped cross section are interposed between them, and the vertical frames 8, 9 and the connecting members 6, 7 are combined.
The frames 3, 4, and 5 are fixed to each other by screws 10.

In addition, each of the upper and lower frames 11 and 12 of the front body 3 and both side slope bodies 4 and 4 that constitute the bay window part A has mounting pieces 14 for the support frames T and T, and tips on the upper and lower opposing surfaces of both the support frames T and T. A protruding leg piece 15 is provided to abut against each other. Further, at the tip of the leg piece 15, there is an outward bending part 1.
5a, and a bent portion 15 is formed on the side surface of the mounting piece 14.
A protruding latch piece 14a is provided opposite to a (second
figure).

Next, the end vertical frame 16 and the upper and lower frames 17, 1 of the sleeve portion 5
8 is provided with a mounting piece 21 that joins to the outer surface of the building frame 19 at the periphery of the opening, and a leg piece 22 that abuts against the inner circumferential surface of the frame body 19. 22a, and on the side of the mounting piece 21 there is a hanging piece 21a that hangs on the inner peripheral surface of the building frame 19.
is formed opposite to the bending part 22a (the first
Fig. 3).

In addition, each vertical frame 8, 9, 16 and upper and lower frames 11, 1
2, 17, and 18 use existing semi-external sashes. Therefore, regarding the existing vertical frame 8A used as the vertical frame 8 of the bay window part A, in order to connect it to the connecting members 6 and 7, the connecting leg pieces 3
5, the unnecessary mounting piece 38 is inserted into the V groove 36.
It can be peeled off or bent in the direction of the arrow at the V-groove 36 as shown by the two-dot chain line 35a (FIGS. 1 and 4).

The upper and lower support frames T, T are trapezoidal frames as described above, but the outer peripheral surfaces are shaped like bay window sashes S.
It is recessed and formed one size smaller than the specified position P where it joins with the mounting piece 14 of the bay window part A (FIG. 5). That is, the front member 2 that constitutes the support frame T
4 and the outer side surfaces of both side slope members 25, 25 are made slightly shorter than the regular lengths.

Effects of the Embodiment When installing the already assembled bay window sash S, first insert the bay window sash S between the upper and lower support frames T, T. In this way, the upper and lower support frames T,
Since T is formed one size smaller, the bay window part A
Since the mounting pieces 14 of the support frames T, T do not come into contact with the outer circumferential surfaces of the support frames T, T, the mounting pieces 21 of both sleeve portions 5, 5 are always joined to the outer surfaces of the building frame 19 (FIG. 3).
In this joined state, a gap 30 is created between the mounting piece 14 of the bay window portion A and the outer peripheral surface of the support frame T (FIG. 2). Therefore, after fixing the mounting pieces 21 of both sleeve parts 5, 5 to the building frame 19 with screws 20, a complementary member 27 is inserted into the gap 30 for each mounting piece 14 in the bay window part A.
The mounting piece 14 is fixed to the support frame T with the screw 13 with the complementary member 27 in between.

This gap 30 has been planned from the beginning, and even if the bay window A is moved in and out a little more than planned, it will not be noticeable, so there is no problem with the appearance when viewed from the inside of the room.

In addition, the gap 30 and the supplementary member 27 are hidden from view by the roof eaves portion 31 and cap 32 that cover the support frames T and T (7th
), there is no problem in terms of appearance.

As the material for the complementary member 27, it is appropriate to use a piece of wood because the thickness can be adjusted by carving it and the screws 13 and 20 can easily pass through it.

Effects of the Invention As explained above, according to the present invention, in order to support the trapezoidal bay window portion of the bay window sash, a pair of upper and lower support frames are assembled in a trapezoidal shape at the center of the window opening on the outer wall of the building. By protruding the outer peripheral surface of the upper and lower support frames and forming the outer peripheral surface of the upper and lower support frames to be slightly smaller than the prescribed position where they are joined to the mounting piece of the bay window section of the sash, the outer peripheral surface of the upper and lower support frames and the bay window section of the bay window sash can be easily connected to each other. Since the mounting pieces on both sleeves can be prevented from coming into contact with each other, the mounting pieces on both sleeves can be firmly attached directly to the building frame, and there is no risk of the bay window sash being installed in an unsightly manner. It has excellent effects.

In addition, when constructing the upper and lower support frames, there is no need to ensure that the support frames closely match the inner circumferential dimensions of the bay window sash, which contributes to improving the efficiency of frame work and reducing costs. There is also the effect that it can be done.
