Description

[Detailed description of the invention] This invention relates to a connection structure of vertical frames in a double sash.

As shown in Figure 1, it is possible to attach a new sash to the outdoor side of an existing sash installed in an opening with external walls or side walls on one or both sides to form a double sash. When installing the sash, the outer wall or side wall may get in the way, making it very troublesome to connect the vertical frames.

This invention was devised in view of the above circumstances, and has an extremely simple structure, and the new sash short frame can be easily attached to the existing sash short frame without any relation to the outer walls or wing walls on one or both sides. It is an object of the present invention to provide a connecting structure of short frames in a double sash.

This invention will be explained below with reference to illustrated embodiments.

A new sash short frame 3 is attached to the existing sash short frame 1, which is provided so as to protrude toward the outdoor side, with a connecting fitting 2 interposed on the outdoor side.

A flange 4 that projects in the direction of the existing short sash frame 1 on the opposite side is formed continuously in the vertical direction at the tip of the existing short sash frame 1 on the outdoor side.

At the indoor end of the new short sash frame 3, a flange 5 is formed continuously in the vertical direction along the flange 4 and has the same length as the flange 4 and projects in the direction of the existing short sash frame 1 on the opposite side. be.

The connecting fitting 2 includes a clamping part 6 formed in a short groove shape that opens laterally so that the flanges 4 and 5 can be clamped from the lateral direction simultaneously, and a clamping part 6 formed in a short groove shape that opens in the horizontal direction, and a short frame of the existing sash from the open end of the clamping part 6. 1 or along the inner surface of the newly installed short sash frame 3 (in the embodiment, the inner surface of the newly installed short sash frame 3).

A through hole 8 is formed in the mounting portion 7.
The connecting fitting 2 is fixed to the inner surface of the existing short sash frame 1 or the newly installed short sash frame 3 by screws 9 passing through the sash 9.
In the embodiment, the inner surface of the newly installed short frame 3).

The connecting fitting 2 formed in this way allows the flanges 4 and 5 of the existing short sash frame 1 and the new short sash frame 3 to be fitted into the clamping part 6 at the same time, and a screw that passes through the through hole 8 of the mounting part 7. 9, a plurality of pieces are fixed in the vertical direction on the inner surface of the newly installed short sash frame 3.

Therefore, the newly installed short sash frame 3 is fixed to the existing short sash frame 1.

The existing sash short frame 1 is attached to the indoor end of the new sash short frame 3.
A flange 10 is formed along the outer surface of the flange 10, which protrudes toward the interior of the room, and plays an auxiliary role of the connecting fitting 2, such as preventing the newly installed short sash frame 3 from shifting laterally.

In addition, if the connecting fitting 2 is formed to be slightly elongated in the vertical direction and a plurality of through holes 8 in the mounting portion 7 are formed in the vertical direction, the connection between the existing short sash frame 1 and the new short sash frame 3 can be achieved. become certain.

In addition, as shown in FIG.
It will look good if a recessed hole 10 in which the mounting part 7 can be embedded is formed in the inner side surface of the newly installed short frame 3 that the sash 3 comes into contact with, and the mounting part 7 is fixed in this recessed hole 10.

Note that the recessed hole portion 10 may be formed continuously in the vertical direction of the newly installed short sash frame 3 in the shape of a groove.

FIG. 5 shows a modification of this invention.

The following will explain the embodiments shown in the drawings.

The connecting fitting 11 has a width equal to the width of the flanges 4 and 5 formed on the existing short sash frame 1 and the new short sash frame 3, and clamps the flanges 4 and 5 in the longitudinal direction at both upper and lower ends at the same time. A horizontal groove-shaped fitting portion 12 is obtained.
．． 12, and a mounting part 14 protruding from one end of the clamping part 13 along the inner surface of the newly installed short sash frame 3.
It is formed by

A through hole 8 is formed in the mounting portion 14, and the connecting fitting 11 can be fixed to the inner surface of the newly installed short sash frame 3 by means of a screw 9 passing through the through hole 8.

The connecting fitting 11 formed in this way is attached to the existing sash short frame 1.
and flanges 4 and 5 of the newly installed short frame 3
The upper and lower opening ends of the cutout portion 15 formed in Multiple pieces are fixed in the vertical direction.

Therefore, the newly installed short sash frame 3 is connected to the existing short sash frame 1.

This invention consists of the above-mentioned structure, and includes a clamping part that can simultaneously clamp the existing short sash frame protruding from the outdoor side and the flange protruding from the inner surface of the new vertical sash frame, and the existing short sash frame or The new sash short frame is connected to the existing sash short frame through a connecting fitting consisting of a mounting part that can be fixed to the inner surface of the new sash vertical frame. When installing a new sash on the outside of an existing sash, which is installed in an opening with an exterior wall or side wall, the outside wall or side wall gets in the way when installing a new sash on the outside of the existing sash. The installation is not troublesome, the newly installed short frame can be easily installed, and the structure is extremely simple.
