Description

[Detailed Description of the Invention] The present invention relates to an additional sash that is attached to the outside of an aluminum sash such as a window.

When installing a new screen door, rain door, shutter, etc. on the outside of a window with an aluminum sash installed, it is sufficient if the existing aluminum sash has a mounting part attached in advance, but if it is not attached, It is not possible to easily replace aluminum sashes, and it is also relatively difficult to install additional sashes to attach screen doors, etc., without damaging parts of the building or damaging the appearance. It is.

The present invention aims to provide an additional sash that can be easily attached to the existing aluminum sash in such a case, and examples thereof will be described below in detail with reference to the drawings.

FIG. 1 shows the state in which the additional sash according to the present invention is attached to an existing aluminum sash.
It forms a support frame for rain shutters, shutters, etc., and the upper and lower horizontal frames 2 and 3 are provided with rails 5 of any shape according to the fittings to be installed, and the outermost rails of the upper and lower bars 7 and 8 of the existing aluminum sash 6 are provided. a groove 11 that fits into the inward protrusions 9 and 10;
12 are formed.

The upper and lower horizontal frames 2 and 3 are made of the same aluminum material as the existing aluminum sash or other appropriate material, and are connected and integrated by left and right side frames made of the same material.

As shown in detail in FIGS. 2 and 3, the groove 11 in the upper horizontal frame 2 is formed on the inner mounting surface 14 of the main body 13 of the horizontal frame 2 with a thickness equivalent to that of the protrusion 9 of the aluminum sash 6. step part 1
Attach the mounting bracket 15 with the screw 1 at its base 17.
8 or the like, it is formed between the mounting surface 14 and the mounting bracket 15.

The holes 19 for inserting the screws 18 in the base 17 of the mounting bracket 15 are preferably vertically elongated holes so that the fixing position of the mounting bracket 15 with respect to the mounting surface 14 can be adjusted in the vertical direction.

The mounting fittings 15 may be provided at a plurality of locations along the length of the horizontal frame 2, as shown in FIG. 3, but may also be installed over the entire length of the horizontal frame 2.

On the other hand, as shown in FIG. 1, the groove 12 in the lower horizontal frame 3 is formed by integrally connecting the projecting wall 21 to one side of the main body 20 of the horizontal frame 3. Although it is formed between the horizontal frame 21 and the upper horizontal frame 2, it can also be formed using the same mounting hardware as in the case of the upper horizontal frame 2.

FIG. 4 shows another embodiment of the mounting bracket fixed to the upper horizontal frame 2. In this mounting bracket 22, similarly to the mounting bracket 15, the wall thickness of the protrusion 9 of the aluminum sash 6 is A corresponding step 23 is provided, and a long hole 24 for inserting a screw is provided on this step 23, and a mounting bracket 2 is provided on this step 23.
A bending protrusion 26 serving as a branch is provided at the lower end of the base 25 of 2, and the protrusion 26 is configured to abut against the lower end of the mounting surface 14 on the horizontal frame body 13.

Therefore, when a screw is inserted into the elongated hole 24 and tightened, the distance between the upper end of the mounting bracket 22 and the mounting surface 14 varies greatly depending on the degree of tightening, and the aluminum sash 6
Even if the thickness of the protrusion 9 varies in size, it can be firmly fixed by tightening.

Addition sash 1 having the above configuration to existing aluminum sash 6
To attach the aluminum sash 6 to the lower frame 8, first fit the groove 12 of the lower horizontal frame 3 into the outermost protrusion 10 of the lower frame 8 of the aluminum sash 6, and then fit the mounting surface 14 of the upper horizontal frame 2 onto the top of the aluminum sash 6. The outermost protrusion 9 on the frame 7 is abutted, the protrusion 9 is held between the mounting brackets 15 or 22, and the screw 18 is secured.
It can be fixed to the horizontal frame 2 by using the following method.

In this case, there is no need to perform any processing on the existing aluminum sash 6.

As described above, according to the additional sash of the present invention, it is possible to install new screen doors, rain shutters, shutters, etc. by attaching it to the outside of the existing aluminum sash, and when installing the additional sash, the upper and lower Since it is only necessary to fit the inward protrusions of the existing aluminum sashes into the grooves formed in the horizontal frame, there is no need to drill holes in the existing aluminum sashes for screw fixing or damage the exterior walls of the building. The installation and removal are extremely easy, since at least the groove in the upper horizontal frame is formed by a mounting bracket with a step corresponding to the thickness of the protrusion. The protruding portion can be firmly tightened at the stepped portion of the mounting bracket, so that the additional sash can be firmly attached to the existing aluminum sash without being rattled without being screwed.
