Description

[Detailed explanation of the idea] This invention relates to a device for attaching a window frame to a bay window.

When a bay window is installed in a window opening in a building, the top plate and base plate generally overhang from the window opening to the outside, and a window frame is formed between these overhangs. What is important is that the window frame portion be firmly mounted between the top plate and the base plate, that the installation work is easy, and that it can be installed as lightweight as possible.

Conventionally, in this regard, by utilizing the hollow part of the vertical frame that forms the window frame, inserting a long bolt between this hollow part and the top plate and the bottom plate, and securing both with nuts. The above three components were to be integrally connected.

Although this connection structure allows for secure installation,
The end of the long bolt must be tightened with a nut in a very special space on the back side of the top plate or base plate, making the installation work troublesome. Long bolts must be prepared, and each vertical frame that makes up the window frame must be attached using long bolts, so there is a problem in that the long bolts account for a large proportion of the weight of the whole. Ta.

This idea was made with attention to the above-mentioned difficulties, and will be explained below with reference to the drawings. Figure 1 shows an example in which a corner bay window, which is a type of bay window, is attached to a window opening 2 opened in a building wall 1. In Fig. 1, a window frame part 5 is interposed between the roofing material 3 and the lower pedestal 4, and a window glass 6 is fitted onto it or attached in a sliding manner. has been done.

In FIG. 2, the top plate 7 on the back side of the roofing material 3 and the corresponding base plate 8 are attached so as to protrude from the window opening 2 toward the outdoor side. A window frame portion 5 consisting of a lower frame 10 and a vertical frame 11 is attached, and for this purpose, an upwardly U-shaped positioning lid mounting bracket 12 is fixed in advance to the window frame attachment position on the back side of the top plate 1 with well-known methods such as screws. A bolt insertion hole 13 is provided through the base plate 8 corresponding to the fixing means.

Further, the upper surface of the upper frame 9 is shaped like an edge 9a having an upwardly U-shaped cross section, and the hollow interior 10a of the lower frame 10 corresponds to the edge 9a.
A washer 14 is fixed in a non-rotatable manner, and a nut 15 is fixed to this washer 14 by known means such as welding.

And the upward U-shaped edge 9a of the upper frame 9 that extends to the window frame portion 5.
is fitted to the mounting bracket 12 to determine the mounting position, and then screw the screws 16 from the upper frame 9 to the mounting bracket 12 or through the mounting bracket 12 to the top plate 1 to fix it. In order to screw in the upper frame 9 from the hollow part 9b as shown in FIG. However, the screw 16 may be screwed in.

Further, the lower frame 10 can be fixed to the base plate 8 by inserting the bolts 11 from the back side into the bolt insertion holes 13 of the base plate 8 and screwing them into the nuts 15 of the lower frame 10.
Before fixing the frame 10 to the base plate 8, a lower pedestal 4 with a substantially stepped cross section that acts as a draining frame is attached to the edge of the overhanging part of the base plate 8, and the lower frame 10 is attached to the base plate via this lower pedestal 4. 8, the indoor side hanging wall 4a and the outdoor side hanging wall 4
b, and can effectively prevent rainwater from entering the room.

In FIG. 2, a nose comb frame 18 is attached to the tip edge of the roofing material 3, and the two are connected watertightly by a caulking material 19.

Further, a window glass 6 is fitted into the window frame portion 5 using a backing 20 and a glass edge presser 21.

Therefore, according to this invention, a mounting bracket for positioning is fixed to the bottom surface of the top plate, and the upward U-shaped upper edge of the upper frame forming the window frame portion is fitted to this mounting bracket. This serves as the mounting reference when installing the window frame between the top plate and the base plate, allowing for accurate installation.The mounting bracket also prevents the upper frame from moving indoors or outdoors, so the mounting bracket and upper It is only necessary to fasten the frame with screws as appropriate; of course, it is not necessary to fasten with screws.

In addition, the bottom frame only needs to be screwed from the back of the main plate to nuts fixed in the hollow interior of the bottom frame.In the end, all that is required is to fit the upper frame to the mounting bracket and fasten bolts to the bottom frame of the main plate, making the installation work easier. It is extremely simple and lightweight since no long bolts are used.

Furthermore, even if the horizontal and vertical widths of the window frame portion change, it can be installed regardless of this, which is advantageous in terms of mass production.
