Description

[Detailed Description of the Invention] This invention relates to a connecting structure of split ends in a step window.

Conventionally, this type of window frame for tiered windows is shown in Figure 1 or Figure 2.
As shown in the representative example in the figure, a blind main body 1, an upper frame 2,
After the lower frame 3 is assembled with fixing screws 4a, 4b, 4c, etc., a caulking material 5 is placed in the groove of the split connecting portion formed by the open body 1 and the upper and lower frames 2, 3.
It is configured to be filled with or fitted with packing 6 to prevent rainwater from entering through the connection.

However, in the conventional structure described above, since it is a retrofit type in which caulking material 5 is filled or packing 6 is fitted after assembling the open body 1 and the upper and lower frames 2 and 3, the on-site assembly work is required. Moreover, there was a problem that it was easy to peel off or come off.

This idea was made in order to improve the problems with the conventional structure mentioned above, and a fitting groove that opens outward is formed in the open body, and the packing can be installed in advance at the factory. The present invention provides a connecting structure for a gap in a step window that is easy to assemble. The present invention relates to a window frame for a step window, in which a split window frame is provided with a window frame at the top and bottom of the window frame, the lower frame of the upper window frame and the extended flange of the window frame are formed upright on this flange. A concave groove opening outward is formed by the hanging flange of the lower frame of the frame and the overlapping part connected by overlapping, and one side is fitted into the fitting groove formed on the lower side of the extending flange. The other side of the packing attached to the blind body is bent so as to cover the opening of the groove and is fitted into the groove, and the blind body and the lower window frame are fixed by fixing screws. It is characterized by

Hereinafter, one embodiment of this invention will be explained in detail based on FIGS. 3 and 4. FIG. 3 is a cross-sectional view of the main parts according to this invention, in which 1 is the blind main body, 2 is the upper frame, and 3 is the lower frame.

The blind main body 1 is provided with an extending flange 1a and an overlapping part 1b with the hanging flange 3a of the lower frame 3 at right angles, and a fitting opening opening outward is provided on the lower side of the extending flange 1a. A stepped locking portion 1c is provided to form a groove 10.

On the other hand, the outer end surface of the upper frame 2 is provided with a locking receiving portion 2a that abuts against the stepped locking portion 1c of the eyeless main body 1, and the outer end surface of the lower frame 3 is provided with a locking protrusion 3b. There is.

Therefore, the overlapping part 1b of the open body 1, the hanging flange 3a of the lower frame 3, and the overlap between the open body 1 and the upper frame 2.
When the lower frame 3 is fixed with the fixing screws 4a and 4b,
A concave groove 11 that opens outward is formed by the extending flange 1a and the overlapping portion 1b of the eyeless main body 1.

FIG. 4 shows a packing 12 according to this invention, which includes an insertion portion 12a that is fitted into a fitting groove 10 formed on the lower side of the extending flange 1a of the open body 1;
It is an elastic body that includes an open body 1 and a covering part 12b that is fitted into a groove 11 formed by the upper and lower frames 2 and 3, and is formed so that it can be bent freely with a notch-shaped bending part 12c. There is. Also, the above packing 12
A lip 12d is provided at the tip of the covering portion 12b.

In order to assemble the slotted part of the stepped window configured as described above, the insertion part 12a of the packing 12 is fitted into the fitting groove 10 of the slotted main body 1 in advance in the factory or before assembly on site. After that, the blind main body 1 and the lower frame 3 and the blind main body 1 and the upper frame 2 are fixed with fixing screws 4a and 4b. After that, the covering part 1 of the packing 12
2b is bent at the bending portion 12c and fitted into the groove 11, and the lip 12c is engaged with the locking protrusion 3b of the lower frame 3 to complete the installation.

As explained in detail above, according to this invention, a fitting groove that opens outward is formed in the main body, so the fitting of the packing can be done in advance in the factory or on-site, or at the site. It can be easily installed even after the main body, upper frame, and lower frame are assembled, and can be selected arbitrarily by the constructor.

Furthermore, since the packing is provided with a covering portion, the groove can be easily covered, and the insertion portion will not come off.

Further, since the concave grooves at the connecting portions between the open body and the upper and lower frames are sealed by packing, practical effects such as being able to reliably prevent rainwater from entering are achieved.
