Description

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

Various proposals have been made to install a new window frame on the outdoor side of an existing window frame to create a double-glazed window, but when installing these, it is necessary to modify the outer wall or the existing window frame, or there is a risk of damage. be.

In particular, during installation, it is difficult to temporarily hold it, and it is also difficult to install it firmly, and the installation structure itself becomes complicated, which increases the amount of time and effort required for installation.

In addition, the temperature of a newly installed window frame that protrudes significantly outdoors will be greatly affected by the outdoor temperature.

If the existing window frame on the indoor side is in direct contact with the new window frame, the outdoor temperature will have a large effect on the indoor temperature via the new window frame and the existing window frame.

In addition, depending on the shape of the existing window frame, the shape of the fittings, and the installation location, it is necessary to adjust the projected direction of the position when installing a new window frame.

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

The existing window frame A is made of sash or other metal as shown in the figure, and has pillars 1, 1. It is fixed to the shield 2 and window sill 3 with screws 5 in contact with their outer surfaces.

An exterior circumference 6, which is framed in a rectangular shape in contact with the outer surface of the vertical flange 4, is attached to the opening body.

An outer wall board 6' is fitted into this exterior circumference 6. The upper frame 7 of the new window frame B has a hook-shaped latching portion 22 consisting of a latching flange 8 extending toward the existing window frame A side and a joining piece 21 extending in the vertical direction.
A recessed groove-shaped mounting portion 23 is formed at the inner tip of the locking flange 8, and a sealing material 9 is mounted thereon.

In addition, a locking flange 11 extending toward the existing window frame side is also provided on the lower frame 10.
and a splicing piece 24 extending in the vertical direction.

Hook-shaped latching portions 22, 25 of the upper and lower frames 7, 10 are latched to the exterior circumferences 6, 6, respectively, in the shape of a seat.

The lower frame 10 has a mounting piece C having a groove-shaped mounting portion 26 at the tip.
Use to fix it to the exterior material.

That is, the mounting piece C is fixed to the lower frame 10 by passing the screw 18 into the elongated screw insertion hole 17 formed in the mounting piece C.

The mounting portions 23 of the upper and lower frames 7 and 1o configured as described above.
26 sealing materials 9 and 2o are inserted, and the newly installed window frame B is fixed to the exterior material with screws 12 and 19.

As described above, the new window frame B is fixed to the circumference 6 and is separated from the existing window frame A.

Therefore, it is insulated by the wooden circumference 6 and the conduction of heat is minimized.

Furthermore, if the width of the circumference 6 in the forward direction is changed, the installation position of the new window frame A can be changed as appropriate.

The short frame 13 has an inwardly protruding tongue piece 14 connected to the exterior circumference 6.
Fix it with screws 15.

Note that the tongue piece 14 can be formed into an angular shape as shown by the chain line.

Further, the short frame 13 is fixed by a mounting piece C attached thereto.

This mounting piece C has a recessed groove-shaped mounting portion 26 formed at the inner tip and a sealing material 16 attached thereto, and an elongated screw insertion hole 17 is provided at the outer tip, and a screw 18 is provided at the outer tip. .19 to fix the short frame 13.

Further, this mounting piece C can also be provided on the lower surface of the lower frame 1o, and is attached using screws 18 and 19.

20 is a sealing material. Furthermore, a similar configuration can also be provided on the upper frame 7.

Since this invention has the above configuration, the following effects can be obtained.

■ The indoor ends of the upper and lower frames of the new window frame are made into hook-shaped latches, and the new window frame can be temporarily attached to the exterior wrap around the upper and lower frame parts, so the new window frame can be attached to the existing window frame. It can be quickly and accurately installed and fixed without causing any distortion on the outside of the room.

@ Since the new window frame and the existing window frame are separated from each other and an exterior wrap is interposed between each frame, it is possible to expect a heat insulating effect between the side window frames.

By changing the expected width of the external circumference, the mounting position of the new window frame can be adjusted as appropriate.
