Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a device for attaching a new sash to the outside of an existing sash to create a double sash.

<<Prior Art>> Conventionally, when converting an existing sash into a double sash, a new sash frame was attached to the existing sash frame or the outer wall of a building using screws or the like.

《Problems that the invention aims to solve》 The demand for installing new sashes on the outside of existing sashes to improve the soundproofing or heat insulation effect has increased in recent years, but in the past, it was not possible to attach new sashes to the existing sash frame or the outer wall of the building using screws, etc. Not only was the installation work complicated, but it also caused damage to the sash and buildings, as well as causing rain leaks.

In view of the above points, the present invention is to install a new sash outside without damaging the existing sash or building.
The purpose is to improve the double satsushi.

<Means for Solving the Problems> In order to solve the above problems, the present invention provides that one bent piece 2 of the connecting member 1, which is a long plate with a substantially U-shaped cross section, is connected to the outdoor side of the existing sash A. At the same time, the other bent piece 6 is inserted into the inside of the vertical frame 7 and the upper and lower frames 8, 9 on the indoor side of the newly installed sash B, respectively. A bracing member 10 made of a short plate with a substantially U-shaped cross section is inserted into the connecting member 1 installed between the existing sash A and the new sash B from the outside of the connecting member 1 with the bent pieces 11 facing inward. At the same time, the tension member 10 is attached to the connecting member 1 with the bolt 1.
It is made by tightening with 2.

<<Operation>> Next, the operation of the present invention will be explained based on the drawings.
With double-sliding aluminum sashes, there is always a gap between the vertical frame of the sash and the vertical frame of the glass shoji.

Therefore, the present invention involves inserting a connecting member into this gap and sandwiching it with a new sash that is attached to the outside.
If one bent piece 2 of the connecting member 1 is inserted into the inside of the connecting member 1, and the other bent piece 6 is inserted into the inside of the vertical frame 7 on the indoor side of the newly installed sash B, the load of the newly installed sash B will be received by the connecting member 1, and both Satoshi A and B are connected.

Next, insert one bent piece 2 of the connecting member 1 into the upper frame 4 and the lower frame 5 on the indoor side of the existing sash A, and insert the other bent piece 6 into the upper frame 8 and the inner side of the new sash B on the indoor side. They are inserted into the inside of the lower frame 9 to close the vertical gap between the existing sash A and the new sash B.

Then, on the outer periphery of each connecting member 1 inserted between the existing sash A and the new sash B, bend the tension member 10 between the existing sash A and the new sash B to the bent piece 11.
If the bolt 12 is inserted inward and the tension member 10 is tightened with the bolt 12 from the inside of the connection member 1, the tension member 10 will be attracted to the connection member 1, and if further tightened, the tension member 10 will be tightened. The flat plate part is curved and warped, and the bent piece 11 widens outward to strongly sandwich both sashes A and B to prevent the connecting member 1 from falling off.

<<Example>> Hereinafter, an example of the present invention will be described based on the drawings. Reference numeral 1 is a connecting member consisting of a long plate body with a substantially U-shaped cross section that connects an existing sash A and a new sash B; One bent piece 2 of the connecting member 1 is attached to the left and right vertical frames 3, upper frame 4, and lower frame 5 on the outdoor side of the existing sash A.
Each one is inserted fully into the inside of the .

In addition, the other bent piece 6 of the connecting member 1 is attached to the left and right vertical frames 7, the upper frame 8, and the lower frame 9 on the indoor side of the newly installed sash B.
Each one is inserted fully into the inside of the .

Reference numeral 10 denotes a strut member consisting of a short plate body having a substantially U-shaped cross section, which is inserted in an appropriate number from the outside into each connecting member 1 installed between the existing sash A and the new sash B; The member 10 is fitted so that the tip of the bending piece 11 contacts the connecting member 1, and when the tension member 10 is tightened from the inside of the connecting member 1 with the bolt 12 and drawn to the connecting member 1, the tension is increased. The flat plate part of the member 10 is curved toward the connecting member 1, and the bent pieces 11 on both sides are spread outward, and the bent pieces 11 sandwich both the sashes A and B between the bent pieces 2 and 6 of the connecting member 1. It is fixed.

13 is a bolt hole drilled in the connecting member 1 and the tension member 10, 14 is a sealing member provided between the outer wall 15 and the newly installed sash B, and 16 is a glass shoji.

<<Effect of the invention>> According to the invention, the newly installed sash B is replaced with the existing sash A.
Since no screws or the like are used on both sashes A and B or on the outer wall 15 of the building, there is no risk of damage and there is no fear of rain leakage.

In addition, since the installation is done by connecting the two sashes A and B with the connecting member 1 and sandwiching and fixing both the sashes A and B with the tension member 10, the installation work can be easily performed and is a useful device. It is.
