Description

[Detailed Description of the Invention] This invention relates to a window frame structure in which a new window frame is attached to an existing window frame to form a double window.

Various proposals have already been made to create double-glazed windows by installing a new window frame in addition to the existing window frame.

However, since most of these are attached to the open frame, it is necessary to modify the outer wall or existing window frame, and there is a risk of damaging them.

Further, there were other problems such as requiring a lot of effort for installation.

This invention was devised to solve the above-mentioned conventional problems, and its details will be explained below with reference to illustrated embodiments.

In the figure, A is an existing window frame, and B is a newly installed window frame.

The lower frame 1 of the existing window frame A and the lower frame 2 of the new window frame B are connected as follows.

That is, the window inner side projecting flange 5 of the lower frame 2 is placed on the screen door rail 4 of the lower frame 1 and connected.

This projecting flange 5 may be inserted into the inner recess of the rail 4 as a single piece, or, as shown in FIG. You can do it like this.

A heat insulating material 7 is interposed between the rail 4 and the protruding flange 5.

Furthermore, during construction, there are cases in which the draining board 8 is completely removed, cases in which it is left attached to the existing window frame A as it is (see Fig. 4), and cases in which it is partially removed (see Fig. 5).

Further, it is preferable that a hanging flange 9 is provided on the lower frame 2 and fixed to the outer wall 10 with screws 11.

Vertical frame 12 and upper frame 13 of existing window frame A and vertical frame 1 of new window frame B
4. When connecting the upper frame 15, use a bracket C.

That is, the vertical flanges 16 of the vertical frame 12 and the upper frame 13 and the protruding flanges 17 of the vertical frame 14 and the upper frame 15 are sandwiched between the receiving metal fitting C with the heat insulating material 7 interposed therebetween, and this receiving metal fitting C The base ends of the vertical frame 12 and the upper frame 13 are connected to each other by being fixed to the outdoor sides thereof with screws 18.

The side flanges 19 of the vertical frame 14 can be fixed to the circumference 20 and other outer walls with screws 21.

By the way, the screen door dimensions H of the existing window frame A and the new window frame B,
If W is the same, the screen of the existing window frame A can be used as is for the new window frame B.

Furthermore, the newly installed window frame B is arranged along the outer wall 10 and is fixed to the building frame.

For example, if the lower frame 2, left and right vertical frames 14, 14, etc. are each fixed at two locations, sufficient mounting strength for the newly installed window frame can be ensured.

As mentioned above, the lower frame 2 of the new window frame B is equipped with a drain plate 8 provided on the lower surface of the lower frame 1 on the outdoor side of the existing window frame A, or a cover piece that covers the exterior material near the bottom of the building opening. By providing the (hanging flange 9), the external appearance can be improved.

This invention has the above-described configuration, and the new window frame can be positioned with respect to the existing window frame by the lower frame portion of the existing window frame, and the installation of the new window frame can be easily performed.

In addition, the window frame can be retrofitted by integrating with the existing window frame, and the work is simple.

In the end, we were able to provide double-glazed windows with excellent thermal insulation effects.
