JPS6018551Y2 - Airtightness/soundproofing device for sliding doors - Google Patents

Description

[Detailed description of the invention] This invention relates to an airtightness and soundproofing device for sliding doors that aims to make the room airtight and soundproof by closing the space between the formwork and the vertical stile of the sliding door with a backing. To provide an airtightness and soundproofing device for a sliding door which has an extremely simple structure, sufficiently exhibits airtightness and soundproofing effects, and improves the starting performance of the sliding door.

In order to obtain sufficient airtightness and soundproofing effects in the room, it is sufficient to place a sufficient amount of backing in the gap between the formwork and the vertical stile, but when starting the sliding door, the backing should be Since it is in close contact with the frame or stile, its surface resistance is large, making it difficult to start the sliding door.

In addition, a pulling device is installed, and only when the sliding door is pulled,
There is also a type that makes the backing close together, but this type has good starting performance of the sliding door, but this requires a special pulling device, which is not only troublesome to install, but also increases the cost. There are drawbacks.

This invention has thus been devised to overcome the above-mentioned drawbacks of the conventional art.

This invention will be explained below based on embodiments shown in the drawings.

In the drawings, reference numeral A designates the backing according to this invention.

The backing A is separated from the mounting base 1 and the close contact portion 2.

The close contact portion 2 has a polygonal shape with a top portion 3 facing the mounting base 1.

In the embodiment shown in the drawings, the close contact portion 2 has a pentagonal shape.

Further, with the top portion 3 as a boundary, a slope located on the vertical stile 4 side of the sliding door B is used as a close contact surface 5.

Further, it is desirable to provide a hollow portion 6 in the close contact portion 2.

The backing A having the above structure is first attached to the flange 8 of the formwork 7 along the longitudinal direction of the formwork 7.

Its installation is done using a backing A in the mounting groove 9 of the flange 8.
This is done by fitting the mounting base 1.

Next, the state of use of this invention will be explained.

First, move sliding door B to close it.

Then, the indoor side surface 10 of the vertical stile 4 of the sliding door B is the backing A.
in close contact with the close contact surface 5 of the

At the same time, the backing A is deformed as shown in FIGS. 2 and 3.

Note that a pull piece 11 is attached to the opposite surface of the vertical stile 4 of the sliding door B that faces the formwork 7, and when the sliding door B is closed, the opposing flange 12 of the bag frame 7 comes into contact with the pull piece 11. , the indoor side surface 10 of the vertical stile 4 of the sliding door B is brought into closer contact with the backing A.

By the way, when sliding door B is closed, backing A is deformed as shown in Figure 3. Backing A after this deformation
, there is a stress that tries to return to the state before deformation.

Therefore, when opening the sliding door B, a slight stress is applied in the starting direction of the sliding door B, thereby improving the starting performance of the sliding door B.

FIG. 4 is a cross-sectional view showing another embodiment of this invention.

That is, the backing A according to this invention is attached to the vertical frame 4 of the sliding door 13, and the close contact surface 5 of the backing A is attached to the opposite side 7 of the bag frame 7.
This allows it to be brought into close contact with the lunge 12.

] This embodiment also has the same effects as those described above and the embodiments.

This invention consists of the following structure.

And if it is an airtight and soundproof device for sliding doors based on this idea,
It makes good use of the elasticity of the backing17, and is structured so that the stress of the backing is applied in the direction in which the sliding door is opened, making it easy to start the sliding door.In addition, the backing has a sufficiently tight surface and has a simple structure. It has the excellent advantage of being able to exhibit sufficient airtightness and soundproofing effects even if it is closed.

[Brief explanation of drawings]

The drawings show an embodiment of this invention. Figure 1 is a cross-sectional view showing the sliding door just before it is closed, Figure 2 is a cross-sectional view showing the sliding door in its closed state, and Figure 3 is a cross-sectional view showing the sliding door in its closed state. FIG. 4 is an enlarged cross-sectional view of the main part showing the deformed state of the backing when it is closed, and FIG. 4 is a cross-sectional view showing another embodiment of this invention.
