Description

[Detailed description of the invention] As a method for attaching a window frame to a window opening in a wooden house, the upper and lower frames and side frames of this window frame are assembled in advance into a peripheral frame shape, and then fitted into the window opening. There is a method in which the upper and lower frames and the vertical frame are made into separate members and these are individually attached to the upper and lower frames and the vertical frame inside the window opening, but in the former method, the frame-shaped integral window The need to fit the frame into the window opening creates a gap between the window frame and the inner periphery of the window opening, and it takes a great deal of effort to close this gap, and in wooden houses, the window opening does not meet the design dimensions. However, the latter method is often adopted because dimensional errors tend to occur and therefore the window frame is difficult to fit into the window opening.

In this latter method, since the upper and lower frames and the vertical frame are individually attached to the inner periphery of the window opening, it is important to have a watertight configuration at the intersection corners of these members, and especially for the lower frame and the vertical frame, where this watertight configuration is most required. At the corner with the vertical frame, conventionally, the edge of the lower frame is bent upward by a required amount to form an upright flange wall, and the lower end of the vertical bar is overlapped with the upright flange wall, and the upright flange In order to improve the fit of the wall within the window, a recessed portion is formed in the vertical beam at a position opposite to the upright flange wall, and the upright flange wall is fitted into the recessed portion.

However, carving a recessed part on the vertical beam to match the upright flange wall is extremely complicated and has poor workability.
This will significantly reduce the strength of the vertical beam.

The present invention has been developed in view of this point.

Hereinafter, one embodiment of the present invention will be described based on the drawings. As shown in FIGS. 2 to 4, the lower frame 1 of the window frame has a horizontal wall portion 2 that is slightly downwardly inclined forward. Several support ribs 3, 3 are protruded from the lower surface of 2, and screw pockets 4, 4 are formed, and rail strips 5, 5 are formed on the upper surface of the side wall 2.
are erected, and a hanging wall 6 for water return is provided on the indoor side of the rail strips 5, 5.

At the end of this lower frame 1, the above-mentioned supporting bones 3 and hanging wall 6 for water return are cut off by the required amount from these end faces, and the edge of the horizontal wall portion 2 is approximately equal to the hanging wall 6 for water return. It is bent upward at a right angle to form an upright flange wall 7, and a required amount of the rail strips 5, 5 are cut off inside the upright flange wall 7.

Thus, the lower frame 1 is fitted into the window opening with a coating material 8 such as plate putty applied to the outer surface of the upright flange wall 7, and the upright flange wall 7 is adhered to the vertical beam 9a via the coating material 8. It is placed on the lower crosspiece 9b in a fixed state, and the through hole 10 (see FIGS.
By driving a wood screw through the lower frame 9b into the lower frame 9b.
It is fixed at b.

On the other hand, the vertical frame 11 is provided with an outdoor decorative edge 13 and an indoor decorative edge 14 on both indoor and external edges of the base plate 12, extending perpendicularly to the base plate 12 and across the front and back surfaces thereof, and A plurality of supporting ribs 15.15 are provided on the back surface of the vertical frame 11 in the longitudinal direction.

The amount of protrusion of the decorative edges 13 and 14 from the surface of the base plate and the amount of protrusion of the support rib 15 are approximately equal to the length of the upright flange wall 7 plus the coating thickness of the coating material 8.

Thus, each decorative edge 13.
14 and the lower ends of the supporting bones 15 are cut out to match the height of the upright flange wall 7 as shown in FIG.
17 is constructed, and this vertical frame 11 is fitted into the window opening with the decorative edge 13.14 and the supporting frame 15 in contact with the vertical frame 9a, and the upright flange wall 7 is fitted into the engaging portions 16, 17.
The lower end of the vertical frame 11 is superimposed on the upright flange wall 7 from the outside in a state of engagement with the upright flange wall 7.

Further, the indoor side decorative edge 14 is brought into contact with the outdoor side surface of the water return hanging wall 6 as shown in FIG. 2 and is overlapped.

Next, the vertical frame 11 is fixed to the vertical frame 9a by driving a wood screw into the vertical frame 9a through the through hole 18 (FIGS. 1 and 4) formed in the base plate portion 12.

Further, as shown in FIG. 6, the upper frame 19 is provided with decorative edges 21 and 22 on both indoor and outdoor edges of the horizontal wall portion 20, and between these decorative edges 21 and 22, the rail strips 5 and 5 of the lower frame 1 are installed. Rail strips 23, 23 facing each other are provided protrudingly.

Then, a slit-like cut 24.24 is carved in the base plate 12 at the upper end of the vertical frame 11, and each rail strip 23, 23 of the upper frame 19 is inserted into this slit-like cut 24.24, and the above-mentioned Fit the upper frame 19 and the vertical frame 11 in a state where the decorative edges 21 and 22 are fitted over the vertical frame 11 as shown in FIG.
This upper frame 19 is fixed by driving wood screws 26 into the upper crosspiece 9C through holes 25 opened in the horizontal wall portion 20.

This allows the upper and lower frames 19, 1. And the vertical frame 11 is fitted and attached like a peripheral frame.

In the present invention, as described above, the upright flange wall 7 of the lower frame 1 is fixed to the vertical frame 9a via the coating material 8, and the lower end of the vertical frame 11 is superimposed on the upright flange wall 7. , the watertight structure at the intersection corner portion of the lower frame 1 and the vertical frame 11 is ensured.

Moreover, the indoor/outdoor decorative edges 13.14 on the side of the vertical frame 11 and the lower ends of the supporting bones 15 are cut out, and the upright flange wall 7 is engaged with the cut-out retaining parts 16.17. Since the vertical frame 11 is overlapped with the flange wall 7, even if the upright flange wall 7 is inserted and interposed between the vertical frame 9a and the vertical frame 11, the upright flange wall 7 fits well. By interposing the frame 11, the vertical frame 11 does not float from the vertical frame 9a and a gap does not occur between the two.

Therefore, the present invention eliminates the need for machining to cut a recessed portion on the side of the vertical beam 9a and to accommodate the upright flange wall 7 in this recessed portion.

In the above embodiment, the upright flange wall 7 was formed by bending the edge of the horizontal wall of the lower frame 1.
As shown in the figure, it may be manufactured from another member 7', and this member 7' may be attached to the lower frame 1 with screws 27 using the screw pockets 4 of the lower frame 1.

Further, in the above embodiment, the vertical frame 11 is attached to the upright flange wall 7.
When polymerizing the indoor decorative edges 14 of the vertical frame 11,
Since the water return vertical wall 6 is overlapped so as to be in contact with the outdoor side surface of the vertical wall 6, the connecting posture of the lower frame 1 and the vertical frame 11, that is, the overlapping posture of the vertical frame 11 with respect to the upright flange wall 7 is the same as that of the indoor decorative edge 14. Although there is an advantage that the correct position can be achieved by the abutment relationship between the wall 6 and the hanging wall 6, as shown in FIG.
When the vertical frame 11 is superimposed on the upright flange wall 7, the indoor side decorative edge 14 rides on the water return hanging wall 6, and both members 6.
14 may be made flush.

This flush state improves the appearance of the outdoor intersection corner.

Furthermore, as shown in FIG. 9, a slit-shaped cut 29 is provided at the lower end edge of the vertical frame 11 close to the indoor side decorative edge 14, so that when the vertical frame 11 is overlapped with the upright flange wall 7, it can be used for water return. As the hanging wall 6 engages with the notch 29, the indoor decorative edge 1
4 may be brought into contact with the indoor side surface of the hanging wall 6 for water return and polymerized.

In this case, due to the mutual engagement between the slit-like cut 29 and the hanging wall 6 for water return, and the abutment relationship between the indoor decorative edge 14 and the hanging wall 6 for water return, the vertical frame 1 is attached to the upright flange wall 7.
There is an advantage that the superposition position of No. 1 is more correctly regulated.

As mentioned above, the present invention eliminates the need to carve a recess in the vertical frame to accommodate the upright flange wall when the lower end of the vertical frame overlaps the vertical flange wall of the lower frame. The installation work is simplified and work efficiency is improved, and the strength of the vertical beam is not unduly impaired.
