Description

[Detailed description of the invention] The present invention relates to a mounting structure for an airtight material to be attached to the lower stile of a sash shoji. Sufficient airtightness is ensured regardless of the size of the gap between the shoji and the lower stile.

Traditionally, in satsushi, the airtightness between the shoji and the bottom frame was ensured,
To prevent wind and rain from blowing in from the bottom frame of the shoji, an airtight material is fixed along its entire length inside the bottom stile of the shoji, and the tip of this airtight material is attached to the side of the rail installed vertically above the bottom frame. I was trying to make them touch each other.

However, in general, in the lower frame of a sash, a part of the rail is removed for the purpose of discharging dust that has accumulated on the lower frame, especially between the rails, so in this removed part of the rail, There was a drawback that the airtight material did not come into close contact with the rail, and the airtightness between the sash bottom frame and the shoji was impaired.

As one means for improving such inconveniences, there is a technique in which the tip of an airtight material fixed to the lower stile is brought into contact with the surface of the lower frame of the sash.

Although it is true that by doing this, airtightness can be ensured even if the rail has a cut-out portion, it has the following practical drawbacks.

In other words, in general, when installing a shoji into a sash, it is necessary to adjust the spacing of the shoji, and the height of the door roller is adjusted accordingly. The interval between the two is different for each satsushi.

Therefore, when a shoji is built into a sash, if the distance between the bottom frame surface and the bottom stile increases, the tip of the airtight material fixed to the bottom stile will no longer bend over the bottom frame surface, making it impossible to maintain airtightness. .

Furthermore, when the distance between the bottom frame surface and the bottom stile becomes extremely small, the airtight material is strongly pressed against the bottom frame, resulting in deformation and damage, or hindering the smooth opening and closing of the shoji.

Furthermore, since the airtight material fixed to the lower stile protrudes from the lower edge of the lower stile, if the shoji with the airtight material attached is placed on the floor etc. when packing the sash components or inserting the glass, There was also the risk that the protruding airtight material would be pressed against the floor and damaged.

The present invention was made to solve the above-mentioned drawbacks of the conventional airtight material mounting structure, and the airtight material is rotatably attached to the lower stile of the shoji, and the tip of the airtight material is Even if the distance between the sash bottom frame and the shoji bottom stile changes by bringing it into contact with the surface of the sash bottom frame, the airtight material will rotate around its fitted part according to the distance, and The present invention aims to provide a new airtight material mounting structure in which the tip of the airtight material moves up and down to ensure airtightness between the lower frame and the lower stile.

Furthermore, the present invention is designed to prevent the airtight material protruding from the lower stile of the shoji from being damaged by storing it in the lower stile when packing the sash members.

Proceeding, the present invention will be explained in detail based on the illustrated embodiment. In the figure, reference numeral 1 indicates a lower frame of the sash, 2 indicates a rail installed vertically on the lower frame 1, and 3 indicates a rail installed within the sash. This is the lower stile of the shoji screen.

At the lower end of the inner surface of the indoor side wall 4 of this lower stile 3,
A mounting groove 5 for airtight material is integrally formed over the entire length of the lower stile 3.

As shown in FIG. 4A, this mounting groove 5 has a pivot portion 5a at the bottom and a floating portion 5b which widens toward the top.
It also has an opening 6 on the - side so as to face slightly downward, and is structured so that the cross section in the thickness direction of the side wall 4 is approximately fan-shaped.

On the other hand, the airtight material 7 has a tongue-shaped airtight material main body 9 protruding from the center of the surface of a flat holding part 8, and the holding part 8 is fitted into the mounting groove 5 of the lower frame 3. At the same time, the tongue-shaped airtight material main body 9 is inserted into the lower stile of the shoji shoji from the opening 6 of the mounting groove 5 so that it can protrude into the lower stile 3.

As the holding part 8 of the airtight material 7 rotates around the pivot part 5a within the mounting groove 5 having a fan-shaped cross section, the position of the tip of the airtight material 7 moves up and down, and is disposed below the lower stile 3. lower frame 1
surface.

In this case, in order for the tip of the airtight material 7 to always be in contact with the surface of the lower frame 1, it is necessary to always give the airtight material 7 a tendency to rotate counterclockwise in the figure. Therefore, when the shoji is assembled into a sash, it is desirable to utilize the wind pressure that blows from outside over the rails 2 of the lower frame 1 onto the upper surface of the airtight material 7.

Of course, a spring or the like may be incorporated into the mounting groove 5 to press the holding part 8 and give the airtight material 7 a tendency to protrude.
It is also possible to distribute the weight of the airtight material 7 so that it is heavier at the tip so that the tip of the airtight material 7 descends under its own weight and comes into contact with the surface of the lower frame 1.

The mounting structure of the airtight material of the present invention is such that the base of the airtight material is rotatably mounted to the lower stile of the shoji as described above, but the shape of the airtight material used for this and its mounting groove are as shown in the figure. It is not limited.

For example, as shown in FIGS. 4 and 5, a mounting groove 5 having a semicircular cross section is integrally formed at the lower end of the inner surface of the lower stile 3, and a cylindrical airtight material 7 is held in the mounting groove 5. 8 may be fitted in a rotatable manner.

As described above, since the present invention has an airtight material rotatably attached to the lower stile, even if the distance between the lower stile surface and the lower stile changes due to adjustment of shoji separation, etc. 1-2
As shown in the figure, the airtight material rotates around the lower part (pivot part) of the mounting groove 5, and the tip of the airtight material moves up and down accordingly, ensuring reliable contact with the surface of the bottom frame, so that a constant airtightness is always maintained. This has the effect of ensuring sex.

As mentioned above, the present invention forms a mounting groove for the airtight material at the lower part of the inner surface of the inner side wall of the lower stile of the shoji, and when installing the airtight material by fitting it into this mounting groove, the shape of the mounting groove is particularly adjusted to This mounting groove has a pivot part at the top, a floating part that expands toward the upper part, and an opening at the side, and has a substantially fan-shaped cross section in the thickness direction of the side wall 4. The holding part of the airtight material is loosely fitted into the mounting groove, and the entire airtight material can freely rotate around the pivot part of the mounting groove, so the conventional fitting part is tightly fitted into the mounting part. Compared to non-rotating shoji, airtightness and water tightness can be ensured even when the shoji is adjusted up and down or moved out of plane, and in addition, when the shoji is opened and closed, the airtight material slides in pressure contact with the bottom frame or rail. , the pressing contact force can be kept constant and unpleasant noises can be prevented from occurring.

In addition, in the present invention, when force is applied to the airtight material from below, the airtight material easily sinks into the lower stile as shown in Figure 3, but when the satsushi is packed or placed on the floor, etc. There is an advantage that there is no risk of the airtight material being stored in the lower stile and being damaged during cargo handling.
