Description

Detailed Description of the Invention (Objective of the Invention) Industrial Field of Application The present invention provides a method for forming step walls on a base plate of a lower frame to provide a low step board and a high step board. erect an outer rail and an inner rail, respectively, and use packing for outer shoji to cover the space between the indoor side of the lower part of the outer shoji and the step wall, and use packing for inner shoji to cover the space between the lower indoor side of the inner shoji and the rain cover of the bottom frame. This relates to the airtight structure of the lower part of the mating stile of sashes (general, soundproof sliding sashes, four-bar sliding sashes, etc.).

Conventional technology For example, as disclosed in Utility Model Application Publication No. 57-68096, an inner rail of a high tier board is sandwiched between the joining part of the lower frame corresponding to the lower end of the inner and outer shoji joining frames when the inner and outer shoji are closed. When the shoji is closed, the sheet-like air and water tight material (fin-shaped piece) protrudes downward from the air and watertight block fitted to the lower end of the inner shoji sill, and when the shoji is closed, the sill board and the lower part of the outer shoji stile are attached. Some are designed to maintain airtightness at the joint by contacting the side of the room. However, according to this device, the airtightness by the sliding plate and the sheet-like air-tight material is the same, and the indoor side is divided by the sliding plate and the sheet-like air-water-tight material. Even if they are pressed together in the best possible condition, rainwater that blows from outside onto the lower part of the inner shoji stile will directly wet the contact area between the sliding board and the sheet-like air/water tight material, and will also leak into the room due to the pressure difference between the indoor and outdoor areas. There was a problem with easy penetration.

Problems to be Solved by the Invention The present invention solves the problems of the prior art, namely:
The problem is that rainwater that blows from outside onto the lower part of a sliding stile, etc., directly wets the seal at the bottom of the stile, and rainwater enters the room from this seal part due to the pressure difference between the indoor and outdoor areas. This is an attempt to solve the problem.

(Structure of the Invention) Means for Solving the Problem A step wall is formed on the substrate of the lower frame to provide a low step board and a high step board, and the low step board is provided with an outer rail and the high step board is provided with an inner rail. In a satsushi in which the rails are set up, and the space between the lower indoor side surface of the outer shoji and the step wall is filled with outer shoji packing, and the space between the inner shoji lower indoor side surface and the rain cover is filled with inner shoji packing, the bottom frame is The joining part or the inner shoji joining frame is provided with a closing member that continuously closes the gap between the lower end of the inner shoji joining frame and the board of the lower frame with the packing for the inner and outer shoji when the shoji is closed. The lower frame is provided with at least an outer shoji sash and an inner rail between the lower end of the shoji sill and the base plate of the lower frame at a position spaced apart from the closing member toward the inner shoji closed side when the shoji is closed. A partition wall piece that closes the gap is fixed, and the high step board on the outdoor side from the inner rail is removed from the lower frame between this partition piece and the blocking member, so that when the shoji is closed, water drops below the stile when the inner shoji is closed. The feature is that a space is provided and this water dripping space is communicated with the outside of the shoji so that the pressure is equal to that of the outside.

According to the above means, when the inner and outer shoji are closed, the closing member continuously closes the gap between the lower end of the inner and outer shoji stile and the base plate of the lower frame, and also closes the gap between the inner and outer shoji packing. Between the stile, the inner rail, and the step wall of the bottom frame, the space between the lower part of the stile and the base plate of the bottom frame is closed with a partition piece, and between this partition piece and the closing member, there is an outdoor By forming a water drainage space with equal pressure, rainwater spraying from outside directly wets the bulkhead piece and does not directly wet the closing member that seals the lower part of the stile. Even if rainwater enters the drainage space between the partition wall piece and the closing member, this drainage space has the same pressure as the outside, so the rainwater is quickly drained outside and prevents rainwater from entering through the closing member. It is something.

Embodiment In FIGS. 1 to 4, 1 is a lower frame, and its base plate 3 includes a low step plate 4, a first step wall 2a rising upward from this, and a high step continuous to this step wall 2a. Board 5
An outer rail 6 is provided upright from the low step board 4, and an inner rail 7 is provided upright from the outdoor end of the high step board 5. A mounting groove 9 for an auxiliary lower frame, which will be described later, is formed on the upper end of the vertical wall 8 of the step wall 2a raised from the lower step board 4 on the outside surface of the room. Reference numeral 10 denotes a rain return piece erected from the indoor side end of the high step board 5, and a mounting groove 11 for an inner shoji packing 11a is formed on the outdoor side surface thereof. Outer and inner shoji screens 12 and 13 are placed on the outer rail 6 and inner rail 7, respectively, so that they can be opened and closed. Reference numeral 14 denotes an auxiliary lower frame that is attached to approximately half of the lower frame 1 facing the outer shoji 12 when closed, using the mounting groove 9 and the engagement piece 7a at the lower end of the inner rail 7. The upper surface of this auxiliary lower frame 14 is set at the same height as the high step board 5, and forms a part of the high step board 5. , the mounting groove 1 for the packing 15a for the outer shoji is provided on the end surface on the outdoor side.
5 is formed at a position higher than the upper end of the outer rail 6. Indoor side piece 16 of the lower stile 16 of the outer shoji 12
The lower end height of a is located above the upper end of the outer rail 6, and when the outer shoji 12 is closed, the lower stile 16 of the outer shoji 12 between the outer rail 6, the low plate 4, and the step wall 2b is located below the outdoor shoji 12. An equal pressure space P1 is formed, and even if rainwater enters the indoor side from the outer rail 6, the height of the rainwater is the maximum height of the outer rail 6 and the outer shoji packing 15a is It is designed to prevent direct rainwater from getting wet. Next, an airtight piece 17a is attached to the lower end of the inner shoji stile 17, which closes the end opening of the shogi stile 17 and straddles the inner rail 7 to make the space between the inner rail 7 and the stile 17 airtight. At the joining part of the lower frame 1 that faces the lower end of the inner shoji joining stile 17 when closed, the inner rail 7 is sandwiched between the upper surface of the high step board 5 and the lower end (airtight piece) of the joining stile 17. Contacting fin pieces 18a, 18b, 19b
Closing members 18 and 19 are installed so as to overlap with the lower end of the stile 17 toward the end in the direction of opening the inner sash (on the right side in FIG. 1). In the closing member 18 on the indoor side of the inner rail 7, the mating end 11ae of the packing 11a for an inner sash and one of the fin pieces 18b (left side in FIG. 2) are in contact with each other as shown in FIG. 2, and the fin piece 18a is These fin pieces 18 are formed so that the upper end of the indoor side is in contact with the lower end of the packing 11a for the inner shoji.
The outdoor ends of a and 18b are in contact with the indoor side surface of the inner rail 7, and the closing member 19 on the outdoor side of the inner rail 7 connects the outer shoji packing 15a and the outdoor side surface of the inner rail 7. and the lower end of the inner shoji stile 17 when the shoji is closed,
The gap between the lower frame 1 and the high-stage plates 5 forming a part of the base plate 3 is closed. The end surface 14a of the auxiliary lower frame 14 is exactly in the same vertical plane as the inner shoji closing side end of the closing member 19, and the closing plate 20 that closes the end surface 14a of the auxiliary lower frame 14 is located on the auxiliary lower frame 1.
It is attached to the end surface 14a of 4. At a predetermined distance from the closing members 18 and 19 of the lower frame 1 toward the inner shoji closing side (left side in FIG. 1), and at a position where it overlaps with the closing side end of the inner shovel joining frame 17 when closed. As shown in FIG. 4, the partition piece 21 is attached. This bulkhead piece 21 includes the smoke return 22a of the outer shoji frame 22, the inner rail 7, and the step wall 2a.
The upper part of the space formed between the lower part of the inner shoji joining stile 17 in between and the base plate 3 of the lower frame 1 facing this is substantially closed. As described above, the auxiliary lower frame 14 is located on the inner shoji closing side (second
(on the left side of the figure), so the inner rail 7
The high plate 5 of the auxiliary lower frame 14 on the outdoor side is not located between the closing members 18, 19 and the partition piece 21, and a water drop space 23 is formed below the center of the inner shoji sill 17, and this water drop The space 23 communicates with the equal pressure space P1 below the outer shoji at its lower part, and also communicates with the outside through the gaps between the partition piece 21, the inner and outer shoji 12, 13, and the low plate 4, and is also under equal pressure. I'm used to space. A drain hole 24 is bored in the indoor side of the inner rail 7 of the high plate 5 corresponding to the water drain space 23, and the space below the drain hole 24 communicates with the water drain space 23. Further, the inner and outer rails 6 and 7 of the lower frame 1 are notched at both ends, respectively, to facilitate sweeping out dirt and the like, and the outer rail 6 is provided with a drainage hole 25. Also, 2
Reference numeral 6 denotes a fitting that makes the inner shoji fitting stile 17 and the outer shoji fitting stile 22 airtight.

According to such a configuration, the inner and outer shoji 12, 1
3 is closed, the airtight piece 17a at the lower end of the inner shoji stile 17 is closed by the fin pieces 18 of the closing members 18, 19.
a, 18b, and 19b, and the outdoor side end of the fin piece 19b is in contact with the outer shoji joining frame 22, and the lower part of the inner shoji joining frame 17 has a closing member 18,
A water drop space 23 having the same pressure as the outside of the outer shoji 12 is formed between the partition wall piece 19 and the partition wall piece 21. When the shoji is closed, when rainwater sprays from the outside onto the lower part of the inner shoji stile 17, this rainwater only directly wets the partition piece 21, and further rainwater blows onto the outer shoji stile 22.
Even if water enters the water drop space 23 through the smoke return 22a or the gap between the lower end of the inner shoji joining frame 17 and the partition piece 21, the water drop space 23 communicates with the equal pressure space P1 at the bottom of the outer shoji 12 and is connected to the outside. Since it is an equal pressure space, rainwater does not accumulate in this water drop space 23 but flows along the outer rail 6 of the lower frame 1, is drained from the drain hole 25 of the outer rail 6, and is drained from the closing members 18, 19.
There is almost no rainwater splashing on the surface, thus stabilizing and improving air-water tightness.

Also, when rainwater blows very hard,
Rainwater crosses the inner rail 7 from the lower stile of the inner shoji and enters onto the high step board 5 on the indoor side of the inner rail 7, causing the high step board 5
The lower end of the inner shoji stile 17 and the fin piece 18a
attempts to enter the room through the seal, but
In this embodiment, the drain hole 24 is bored just in front of the fin piece 18a of the closing member 18, and the high plate 5 on the indoor side of the inner rail 7 is eliminated, so that rainwater that has come down can drain from the drain hole 24. Drained into space 23,
Rainwater does not accumulate in contact with the closing member 18 to the extent that it infiltrates into the room through the seal portion of the closing member 18. However, in normal use, it is rare for rainwater to cross the inner rail 6 and flow onto the high plate 5 on the indoor side of the inner rail 6, so this drainage hole 2
4 may be omitted, or it may be provided at any location on the high plate 5 on the side closer to closing the inner shoji screen than the closing member 18 and on the indoor side of the inner rail 7.

Other Embodiments In FIGS. 5 to 8, the lower frame 1 has a high step plate 5 that protrudes from the inner rail 7 toward the outdoor side, and a mounting groove 15 for an outer shoji packing 15a is provided at the tip over the entire length of the lower frame 1. An outer shoji packing 15a is attached to a mounting groove 15 that is formed and faces the outer shoji 12 when closed. The high step board 5 on the outdoor side of the inner rail 7 of the lower frame 1 has a portion corresponding to the lower end of the inner shoji stile 17 when closed, which is about 2/3 of the width of the inner shoji stile 17. It is notched over the length (L shown in FIG. 6). One end 15A of this notch (right side in FIG. 6) is provided with a fin piece 19b similar to the embodiment described above, sandwiching the mounting groove 15 of the outer shoji packing 15a from above and below on the outdoor side from the inner rail 7 of the high step board 5. Also, a closing member 18 is attached to the high plate 5 on the indoor side of the inner rail 6, and when closed, as in the previous embodiment, the closing member 19 closes to the opening direction of the inner shoji stile 17. Lower end airtight piece 17
a and the upper ends of the fin pieces 18a, 18b, 19b are in contact with each other,
The outdoor end of the fin piece 19b is in contact with the indoor side piece 22b of the outer shoji frame 22. Further, a partition wall piece 21A is attached to the other end 15B of the notch (left side in FIG. 6), and this partition wall piece 2
1A is a main body 21 with a thickness of t that is integrated with a mounting seat 21Aa.
Ab, and fin pieces 21Ac protruding upward and toward the outdoor side from both sides of the main body 21Ab, and the main body 21
As shown in FIG.
It is formed in 1Ad. The indoor end of the fin piece 21Ac and the end continuous to the convex part 21Ad of the main body 21Ab are in contact with the outdoor side surface of the inner rail 7 and the vertical wall 8 of the lower frame 1, and the upper end of the fin piece 21Ac is The lower end of the inner shoji joining frame 17 is in contact with a portion near the end in the direction of closing the inner shoji shoji, and is also in contact with the lower indoor side piece 22b of the outer shoji joining stile 22, so that the outer shoji joining stile 22, the inner rail 7, and the stepped wall The lower part of the inner shoji stile 17 and the lower frame 1 when the shoji is closed between 2a
At least the upper part between the substrates 3 is closed. In this way, by the closing members 18, 19 and the partition piece 21A, when the shoji is closed, there is no high step plate 5 on the outdoor side of the inner rail 7 below the inner shoji joining stile 17, and a water dripping space 23 is formed. The water drop space 23 has a sufficient air passage between the lower part of the bulkhead piece 21A and the low plate 4, and the equal pressure space P below the outer shoji screen as in the previous embodiment.
It communicates with 1 and becomes an equal pressure space.

Even with this structure, rainwater from outside only directly wets the partition wall piece 21A, and in the unlikely event that the fin piece 21Ac of this partition wall piece 21A and the outer shoji joining frame 22 and the inner shoji joining frame 17 Even if rainwater enters the drain space 23 from the contact surface (sealed part), the pressure in the drain space 23 is equal to that of the outside, so the rainwater does not collect in the drain space 23 and flows onto the low plate 4 of the lower frame 1. It is possible to prevent rainwater from falling and being discharged outside the room, and wetting the closing members 18 and 19, thereby improving the sealing performance thereof.

In this embodiment, the closing members 18 and 19 are connected to the lower frame 1.
Although I explained it with a general satsushi fixed to , for example, inside,
It can also be applied to a soundproof sash in which the outer shoji 12 and 13 are pulled together using a known pulling mechanism, and a closing member is installed in the inner shoji sill so that it can be raised and lowered, and the closing member is linked to the pulling handle. When the shoji is drawn, the closing member protrudes downward from the inner shoji stile,
A soundproof sash that continuously closes the gap between the lower end of the inner shoji stile and the high plate of the lower frame with the packing for the inner and outer shoji (for example, Japanese Patent Laid-Open No. 1983, which has already been filed by the applicant) - as shown in No. 178768).

(Effects of the Invention) As described above, the present invention provides the following effects when closing the inner and outer shoji:
A closing member is used to close the gap between the lower end of the inner shoji joining stile and the base plate of the lower frame in a continuous manner with the packing for the outer shoji, and at least the gap between the lower end of the inner shoji joining stile and the base plate of the lower frame is closed. The gap between the connecting stile and the inner rail is closed with a bulkhead piece, and a water drain space is formed below the inner sash between the bulkhead piece and the closing member, and this water drain space is made to have the same pressure as the outdoor area, so the outdoor Even if rainwater sprays onto the lower part of the stile, the rainwater directly wets the bulkhead piece and does not directly wet the seal between the lower edge of the shogi stile and the closing member, which prevents rainwater from entering the room. can be prevented,
Moreover, even if rainwater enters the drainage space through the partition wall piece, the pressure in the drainage space is equal to that of the outdoors, so the rainwater will not accumulate and can be smoothly drained outside. The effect can be improved and stabilized.
