  The present invention relates to a seal structure for a housing sash. More specifically, the present invention relates to a seal structure for a residential sash that closes a gap between the external shoji that is slid into a sash frame of the residential sash and is fitted to be freely opened and closed.

  As shown in FIG. 9, a normal residential sash has two shojis 21 (shoulders located on the indoor side) in a rectangular sash frame 10 composed of an upper frame 11, a lower frame 12, and vertical frames 13 and 14. : Inner shoji), 22 (shoji located outside the door: outer shoji) are fitted in a sliding manner. As a result, the two shojis 21 and 22 are slidable to open and close, and when they are closed, both shojis 21 and 22 are locked by locking the lock member 100 provided between the summing rods 21A and 22A of both shojis 21 and 22. Are attracted to each other.

  Between the shoji 21 and 22 and the sash frame 10, that is, between the upper collars 21 B and 22 B of the shoji 21 and 22 and the sash frame 10, the door toe 21 C and 22 C of the shoji 21 and 22 and the sash frame 10 Both shojis 21 and 22 are closed when locked and unlocked between the lower saddles 21D and 22D of the shojis 21 and 22 and the sash frame 10 or between the summons 21A and 22A of the shojis 21 and 22. Various sealing materials are provided for effectively reducing the sound entering the indoor side from the outdoor side by closing the gap between the two.

Here, between the summons 21A and 22A of the shojis 21 and 22, for example, as shown in FIG. 10, the seal piece 31b of the sealant 31 and the sealant attached to the summons 21A of the shoji 21 A sealing structure in which 32 sealing pieces 32b are elastically contacted with a substantially plate-like cushioning member 33 attached to the indoor side surface 24a of the opposing shoji summoning cage 22A so as to block between the summing cages 21A and 22A. Conceivable.
The sealing material 31 is integrally formed with a mounting base 31a having a substantially L-shaped cross section and attached to the mounting base 31a so as to cover the surfaces 23a and 23d exposed on the indoor side in the summon 21A of the shoji 21. It consists of a lip-shaped seal piece 31b that protrudes from 31a toward the outer shoji 22 side. Further, the sealing material 32 is integrally formed with the attachment base 32a attached to the outdoor side surface 23b of the summing bowl 21A and the attachment base 32a, and is projected from the attachment base 32a toward the outer obstacle 22 side. It consists of three lip-shaped seal pieces 32b.
The sealing piece 31b of the sealing material 31 and the sealing piece 32b of the sealing material 32 are juxtaposed on the outdoor side surface 23b of the summing bowl 21A of the inner shoji 21. The sound-insulating effect is exhibited by elastically contacting the buffer member 33 attached to the.

Further, as shown in FIG. 12, the hollow seal portion 35b of the sealing member 35 attached to the summing rod 21A of the inner shingle 21 is elastically brought into contact with the surface 24a of the opposing outer armor summing rod 22A. A seal structure that closes the space between the summon bowls 21A and 22A is known (for example, Patent Document 1).
The sealing material 35 is integrally formed with the attachment base 35a attached to the outdoor side surface 23b of the summon 21A of the inner limb 21 and the attachment base 35a so as to bulge and curve from the attachment base 35a toward the outer obstacle 22 side. It is composed of a projecting annular hollow seal portion 35b, and when both the shojis 21 and 22 are closed, the hollow seal portion 35b is in direct elastic contact with the summing rod 22A of the outer shoji 22 to exert a soundproof effect.

JP-A-10-77770 (FIG. 8)

  However, in the case of the seal structure shown in FIG. 10, the seal piece 31b of the seal material 31 has a lip shape with a substantially tongue-like cross section, so that the seal piece 31b is inverted as shown by the dotted line in FIG. There is a risk that the seal will break. The sealing piece 32b of the sealing material 32 also has a lip shape with a substantially tongue-shaped cross section, and although not shown, there is a possibility that partial sealing may occur as with the sealing piece 31b of the sealing material 31. .

If there is a risk of the seal being broken in this way, a long-term stable sealability is not ensured, and if the seal is actually broken, there is a problem that sound or rainwater enters the room from the outside through the gap m There is. Further, since the seal pieces 31b and 32b are elastically contacted by point contact with the shock absorbing member 33 attached to the summing rod 22A of the external shoji 22, the sealing function is not sufficient and the soundproofing effect is low.
Further, since sealing is performed by using two parts such as the sealing materials 31 and 32, assembling takes time and costs are increased.

On the other hand, in the case of the seal structure shown in FIG. 12, only the seal material 35 having the hollow seal portion 35b is provided, so that the assembly can be easily performed and the cost is increased as compared with the two-part one. In addition, in order to elastically contact the summoning cage 22A of the external shoji 22 by surface contact, the sealing pieces 31b and 32b are elastically contacted as in the sealing structure shown in FIG. Excellent sealing performance compared to
However, since the hollow seal portion 35b is simply elastically contacted and sealed to the summing rod 22A on the flat surface of the outer shoji 22, the space between the summing rods 21A and 22A of both shojis 21 and 22 is reduced. If there are variations in the gap, there is a problem that the sealing performance becomes insufficient.

  Accordingly, an object of the present invention is to provide a seal structure for a housing sash that can be easily assembled and reduced in cost, and has an excellent sealing function.

In order to achieve the above-mentioned object, the invention according to claim 1 is directed to a summing gutter (22A) and a prag ( 21) a sealing structure that closes the space between the summoning bowl (21A),

  A housing sash seal structure according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a seal structure of a sash for a house according to an embodiment of the present invention, showing a state in which the shoji is opened, and FIG. 2 shows a state in which the shoji is closed in the seal structure of the sash for house shown in FIG. This corresponds to the enlarged sectional view taken along line AA in FIG. The same parts as those shown in the conventional example are denoted by the same reference numerals.

  The seal structure of the housing sash according to the embodiment of the present invention is a summing bowl 22A of a rehabilitator 22 that slides into a sash frame 10 similar to that shown in FIG. The rubber seal is attached to the summing collar 21A side of the inner shoji 21 and the sealing material 51 attached to the summing collar 21A side of the inner shoji 21 It is comprised from the buffer member 52 which consists of an elastic body.

  The sealing member 51 is integrally formed with the attachment base 51a attached to the summon 21A of the inner shoji 21 and the attachment base 51a. When the two shojis 21 and 22 are closed, the summing stick 22A of the outer shoji 22 faces each other. A hollow seal portion 51b that elastically contacts the surface 24a, and a fin piece 51c that protrudes from the hollow seal portion 51b and elastically contacts the side surface 24c side of the summing rod 22A of the shoji 22 when both the shojis 21 and 22 are closed. Yes.

  The mounting base portion 51a of the sealing material 51 has a substantially L-shaped cross section that is mounted along the vertical direction in which the summoning rod 21A extends, and the indoor side surface that is exposed to the indoor side of the summing rod 21A. It is attached so that 23a and the side surface 23d on the opposite side to the side surface 23c to which the inner sward 21 is attached may be covered. Moreover, the thickness of the attachment base 51a on the side covering the indoor side surface 23a of the summon bowl 21A is thicker than the thickness on the side covering the side face 23d, and the attachment base 51a is integrated with the summon bowl 21A.

The hollow seal portion 51b of the sealing material 51 is provided so as to bulge and bend toward the outdoor side from the outdoor side surface 23b of the summing bowl 21A of the inner shoji 21. It is configured to elastically contact a substantially plate-like cushioning member 52 attached to the indoor side surface 24a side, here the indoor side surface 24a.
Further, the hollow seal portion 51b is spaced from the outdoor side surface 23b of the summoning bowl 21A and extends substantially parallel to the outdoor side surface 23b, and from the side 23c side end of the horizontal site P toward the outdoor side surface 23b. Inclined part Q which inclines so that it may approach. And the position of the outdoor side surface of the horizontal part P of the hollow seal part 51b is set to the outdoor side rather than the position of the indoor side surface of the buffer member 52 attached to the indoor side surface 24a of the summoning bowl 22A. When 21 and 22 are closed, the hollow seal portion 51b elastically contacts the buffer member 52 from the inclined portion Q, and further, the hollow seal portion 51b changes the elastic contact position from the inclined portion Q to the horizontal portion P as the both shojis 21 and 22 are closed. Thus, the sealing area and the sealing force are gradually increased.

  The fin piece 51c of the sealing material 51 is a taper extending from the connecting portion of the mounting base portion 51a covering the corner portion of the indoor side surface 23a and the side surface 23d of the summit bowl 21A and the hollow seal portion 51b to the outdoor side. It is curved from the side surface 23d of the collar 21A toward the side surface 23c on the side where the inner impingement element 21 is attached. And when both the shojis 21 and 22 are closed, the fin piece 51c has an inner surface (a surface on the side surface 23c side of the summing bowl 21A) on the side face 24c side of the summing bowl 22A of the shoji screen 22, here the summing bowl 22A. It is made to elastically contact the side surface of the cushioning material 52 attached to. The fin pieces 51c may be directly brought into elastic contact with the side surface 24c of the summing bowl 22A together with the side face of the cushioning material 52, or may be directly brought into elastic contact with only the side face 24c of the summing bowl 22A.

The material of the sealing material 51 and the buffer material 52 is not particularly limited, but is a rubber-like elastic body made of a solid rubber material such as EPDM rubber or a solid resin material of a thermoplastic elastomer. The stability when attached to the 22 summoning tubs 21A and 22A and the opening and closing of the shojis 21 and 22 are improved.
Further, in order to reduce the weight of the sealing material 51 and the buffer material 52, instead of a solid material, a sponge material caused by fine foaming, a sponge material in which foamed bubbles can be clearly seen, or a part of a sponge material may be used. For example, in the sealing material 51, the hollow seal portion 51b and the fin piece 51c that perform a sealing function are made of soft olefin elastomer (TPO), styrene elastomer (TPS), vinyl chloride (PVC), EPDM sponge (specific gravity 0.4). ~ 0.8), and the mounting base 51a, which is the other part, is made of hard, polypropylene (PP), olefin elastomer (TPO), styrene elastomer (TPS), PVC (PVC), EPDM solid It is conceivable to form with a material such as (specific gravity 0.8 to 1.2).

  Further, a sliding material such as aqueous silicone is applied to the elastic contact portion of the hollow seal portion 51b, or the sliding material is attached or coextruded to further improve the opening / closing performance of the both shojis 21 and 22. You can also.

According to the seal structure of the sash for a house as described above, the space between the summing rod 22A of the outer shoji 22 and the summing rod 21A of the inner shoji 21 that are slidably fitted into the sash frame 10 so as to be freely opened and closed. In addition to elastically contacting the hollow seal portion 51b provided on the side of the summing collar 21A of the inner shoji 21 with the cushioning material 52 attached to the opposing surface 24a side of the summing collar 22A of the outer shroud 22, Since the piece 51c is elastically contacted with the side face 24c side of the summon 22A of the external shoji 22, there is no fear that the hollow seal portion 51b and the fin piece 51c are reversed and the seal is partially broken.
In particular, since the fin piece 51c is elastically contacted by surface contact with the side surface 24c instead of the opposing surface 24a side of the summing rod 22A of the external obstacle 22, a sufficient amount of elastic contact can be secured. As a result, a long-term stable soundproofing effect and an excellent sealing effect against rainwater and wind can be obtained.
Further, since the hollow seal portion 51b and the fin piece 51c are one component together with the mounting base portion 51a, the number of components can be suppressed, thereby facilitating the assembly to the sash frame 10 and reducing the cost.
Further, the fin piece 51c elastically contacts the side wall 24c side of the summing bowl 22A of the external shoji 22 so as to cover the space between the summing bowls 21A and 22A of both shojis 21 and 22 from the outside. Nice looking.

  Further, a buffer member 52 made of a rubber-like elastic body is provided on the opposing surface (inner side surface) 24a of the summon 22A of the external shoji 22, and the hollow seal portion 51b of the sealing material 51 is formed by the both shojis 21 and 22. Since the elastic seal member 52 is elastically contacted when closed, the soundproofing effect, the sealing effect, and the heat insulating effect are improved as compared with the case where the hollow seal portion 51b is directly elastically contacted with the summoning ridge 22A of the external obstacle 22.

  Further, the attachment base 51a of the seal material 51 has a substantially L-shaped cross section, and is attached so as to cover the indoor side surface 23a and the side surface 23d, which are the surfaces exposed to the indoor side, in the summoning bowl 21A of the inner shoji 21. Appearance is good in appearance.

  In the embodiment of the present invention, the hollow seal portion 51b of the sealing material 51 attached to the summing candy 21A of the inner shoji 21 is elastically brought into contact with the cushioning material 52 attached to the summing candy 22A of the outer shoji 22. However, in particular, it may be elastically contacted directly with the summoning cage 22A of the external shoji 22 to which the cushioning material 52 is not attached. That is, since a double seal structure with the seal piece 51c is provided between the summoning bowls 21A and 22A in addition to the hollow seal portion 51b, sufficient sealing performance can be obtained.

  As shown in FIGS. 3 and 4, when both the shojis 21 and 22 are closed on the side of the cushioning material 62 attached to the summing cage 22 </ b> A of the outer shoji 22, the hollow seal portion 51 b of the sealing material 51 is formed. You may make it provide the hollow part 62b elastically contacted. The cushioning material 62 is composed of an attachment base 62a attached to the indoor side surface 24a of the summon 22A of the external shoji 22 and a hollow portion 62b integrally formed with the attachment base 62a and further bulging and curved indoors. 62b is a cross-sectional substantially arc shape which gradually increased the amount of protrusion toward the inner shoji 21 from the end to the center.

According to this, since hollow parts, such as the hollow seal part 51b of the sealing material 51 and the hollow part 62b of the buffer material 62, are elastically contacted by surface contact, it is reliably sealed by the mutual reaction force, and long-term and stable sealing performance Is obtained.
Further, the hollow portion 62b of the cushioning member 62 has a substantially arc-shaped cross section in which the protruding amount toward the inner shoji 21 side is gradually increased from the end portion to the center portion, so that the seal area and the seal are increased as both the shoji screens 21 and 22 are closed. The force increases and the seal is ensured.

  Further, if the cushioning material 62 having the hollow portion 62b is attached to the summoning cage 22A of the external shoji 22, and the hollow sealing portion 51b and the hollow portion of the sealing material 51 are elastically contacted by surface contact, the sealing performance is sufficient. Therefore, as shown in FIGS. 5 and 6, the fin pieces 51 c may not be formed on the sealing material 51.

  Further, in the embodiment of the present invention, the exposed bases 23a and 23d of the summing bowl 21A of the inner shoji 21 are covered with the mounting base 51a of the sealing material 51. However, as shown in FIGS. The mounting base 61a of the sealing material 61 is disposed on the outdoor side surface 23b of the 21 summoning bowl 21A, and the hollow sealing portion 61b is formed integrally with the mounting base 61a and bulges and curves outwardly. You may make it provide the fin piece 61c which elastically contacts the side face 24c side of the summoning cage | basket 22A of the external shoji 22 at the time of closing the shoji screens 21 and 22 and blinds the clearance gap between both summoning cage | baskets 21A and 22A.
