Description

  The present invention relates to a sash.

  As described in Patent Document 1, the conventional lower frame of the sash with a flat upper surface of the lower frame is provided with a plurality of upper surface members divided in the prospective direction on the upper surface of the lower frame base member, The outer slide slide drain groove 14a into which the hanging piece is inserted, and the inner slide slide drain groove 14b into which the hanging piece of the inner peg is inserted are formed. As shown in FIG. 5 of Patent Document 1, the water that has entered the outer slide slide drain groove 14a is drained to the outside via drain holes A1 and A2 provided in the upper surface member and the lower frame base member ( Drainage route A). The inner slide slide drain groove 14b is divided into an outdoor space (side where the inner shoji is located) and an indoor space (side where the outer shoji is located) by a water stop member 80 attached to the lower part of the calling position. As shown in FIG. 7 of Patent Document 1, water that has entered the outdoor space of the drain groove 14b passes through drain holes D1, D2, D3, D4, D5, and D6 provided in the upper surface member and the lower frame base member. As shown in FIG. 5 of Patent Document 1, the water drained outdoors (drainage path D) and entering the indoor space of the inner slide slide drain groove 14b is drain holes B1, provided in the upper surface member and the lower frame base member. It is once poured into the lower frame hollow portion 14c via B2 and B3, and drained to the outside through the drain hole 18 to which the check valve 18a is attached.

As described above, the lower frame of the conventional flat sash has a high cost because it has a large number of parts, a complicated drainage path, and a large number of drainage holes need to be processed. Further, since water is drained via the space below the top member (drainage paths A and D), the space below the top member is partly an outdoor atmospheric pressure region, and the space below the top member Could not be used as a wastewater storage space over the entire length of the lower frame, and sufficient wastewater treatment capacity could not be secured.
As a measure for improving the water tightness and drainage of the lower frame, the height of the hollow portion 14c of the lower frame base member is increased to increase the amount of water that can be stored in the hollow portion 14c to increase the water tightness. It may be possible to improve or improve the drainage by increasing the difference in height between the water inlet and outlet to the hollow portion 14c, but then the overall height of the lower frame also increases, so the appearance deteriorates. Or other sashes and shojis are not compatible.
The sash with the rail protruding on the upper surface of the lower frame has the same problem because the water that has entered the indoor region is drained to the outside through the hollow portion of the lower frame.

As shown in FIG. 8, the drainage member 4 on the left side when viewed from the indoor side forms a notch portion 46 corresponding to the shape of the outer panel guide groove 5 on the contact surface 45 with the lower frame auxiliary material 27, By providing a digging portion 47 that is inclined downward toward the outdoor side so as to communicate with the cutout portion 46, a drainage channel 8 that communicates with the outside from the outer frame guide groove 5 of the lower frame auxiliary member 27 is provided. is there. The drainage channel 8 is formed so that the connecting portion (the bottom surface of the cutout portion 46) with the outer obstacle guide groove 5 is the same surface as or lower than the lower surface of the outer obstacle guide groove 5, and gradually increases from there to the outdoor side. I try to lower it.
Each drainage member 3, 4 has a plurality of side surfaces 48 on the outer peripheral side that are in close contact with the inner peripheral side surfaces of the collar frames 2 a, 2 b with a sealer 49 and that protrude from contact surfaces 42, 45 with the lower frame auxiliary material 27 The protruding piece 50 is engaged with and attached to the lower frame auxiliary member 27. Since the drainage channels 7 and 8 of the drainage members 3 and 4 communicate with the outdoor side, they are at the same pressure as the outdoor side.

  As shown in FIGS. 3 and 4, a water stop member 52 is provided on the upper surface of the lower frame auxiliary material 27 below the summing portion 51 of the inner and outer shoji 12 a and 12 b, and the summing portion 51 It prevents rainwater from entering the room from below. Further, a sealing material 71 is provided in the inner shroud guide groove 6 below the summing portion 51, and the sealing material 71 seals the lower end of the inner shroud 12b. The outdoor area and the indoor area are partitioned by the water stop member 52 and the sealing material 71 and the airtight lines 72a and 72b described above. In the inner shroud guide groove 6, the right half region as viewed from the indoor side where the inner shroud 12 b is located is located in the outdoor region, so that it has the same pressure as the outdoor side. Since the left half region is located in the indoor region, it is at the same pressure as the indoor side.

  As shown in FIGS. 1 and 4, the rainwater 53 that has entered the right half area (outdoor area) when viewed from the indoor side where the inner impeller 12 b in which the inner impeller guide groove 6 is closed is located in the chamber of the lower frame auxiliary material 27. Since the drainage member 3 disposed at the right end when viewed from the inside has the drainage channel 7 communicating from the inner guide guide groove 6 to the outside of the room, the drainage member 7 is drained outside through the drainage channel 7 (see arrow 54). ). The drainage channel 7 is formed so that the connecting portion (the bottom surface of the notch 43) with the impeller guide groove 6 is the same as or lower than the bottom surface of the impeller guide groove 6, and gradually increases from there to the outdoor side. Since it is made low, it is possible to drain the rainwater that has entered the inner impeller guide groove 6 to the outside of the room, and the dust that has entered the inner impeller guide groove 6 can be discharged together with the rainwater. Since the bottom wall of the inner impeller guide groove 6 is floated from the upper surface wall 28 of the lower frame main body 26, it is easy to apply a water gradient to the drainage channel 7, and drainage performance is improved.

As shown in FIGS. 1 and 4, rainwater 55 that has entered the inside of the shoji guide groove 5 is formed at the bottom of the shoji guide groove 5 and the outdoor side wall of the lower frame auxiliary material 27 below the shoji guide groove 5. It drains out of the room through the drain holes 56a and 56b. Further, the water is drained also from the drainage channel 8 of the drainage member 4 disposed at the left end as viewed from the indoor side of the lower frame auxiliary material 27 (see arrow 57 in FIG. 4).
The drainage holes 56a and 56b are not formed in the lower frame auxiliary member 27 as described above, and the drainage can be performed only from the drainage channel 8 of the drainage member 4. In this case, labor for processing the drainage holes 56a and 56b is eliminated. Since the drain hole 56b is not exposed on the outdoor side surface, the design is improved and insects can be prevented from entering from the drain hole 56b. The drain holes 56a and 56b can also be formed on the outdoor side wall of the shoji guide groove 5.

  As shown in FIGS. 2 and 4, a drain hole 58a is provided at the bottom of the inner guide guide groove 6 in the left half region as viewed from the indoor side of the external obstacle 12a. Also, drain holes 58b and 58c are provided in the upper surface of the lower frame auxiliary member 27 on the indoor side of the inner shoji rail 37b and the corner portion on the outdoor lower side of the hollow portion 38b on the indoor side of the lower frame auxiliary member 27. . Furthermore, a drain hole 58d is also provided in the upper surface wall 28 of the lower frame body 26 at a position on the indoor side of the hollow portion 38a on the outdoor side of the lower frame auxiliary member 27. Thus, the drainage holes 58 a, 58 b, 58 c, 58 d are provided in the lower frame auxiliary material 27 and the lower frame body 26, and the check valve 33 is installed in the drainage hole 73 provided in the outdoor side wall 32 of the lower frame body 26. In the hollow portion 38b on the indoor side of the lower frame auxiliary member 27, in the hollow portion 59 located outside the inner edge guide groove 6 formed between the lower frame auxiliary member 27 and the lower frame main body 26, The inside of the hollow portion 29 of the lower frame main body 26 is at the same pressure as the indoor side over the entire length of the lower frame 1 in the longitudinal direction.

  Rainwater and condensed water that has entered the indoor area from between the door toe of the outer screen 12a and the frame 2b, or under the summing unit 51, and the like, as indicated by an arrow 60 in FIGS. Flows into the left half of the inner guide guide groove 6 as viewed from the indoor side, and passes through a drain hole 58a formed in the bottom portion thereof and a drain hole 58d formed in the upper surface wall 28 of the lower frame body 26. It flows into the hollow portion 29 of the frame body 26 (see arrow 61) and is drained to the outside through the check valve 33 (see arrow 62). Further, rainwater and condensed water that has entered the indoor side from the inner shoji rail 37b is, as indicated by an arrow 63 in FIGS. 2 and 4, the upper surface of the lower frame auxiliary member 27 and the lower corner portion of the indoor hollow portion 38b. Flows into the hollow portion 29 of the lower frame body 26 through the drain holes 58b and 58c formed in the upper frame wall 28 and the drain hole 58d formed in the upper surface wall 28 of the lower frame body 26, and passes through the check valve 33 as indicated by an arrow 62. Drained outdoors. As described above, in the hollow portion 38b on the indoor side of the lower frame auxiliary member 27, in the hollow portion 59 formed between the lower frame auxiliary member 27 and the lower frame main body 26 on the outdoor side of the inner guide guide groove 6, and Since the inside of the hollow portion 29 of the lower frame body 26 is at the same pressure as the indoor side over the entire length in the longitudinal direction of the lower frame 1, a large amount of water before drainage can be stored in these spaces. Even if the height of the lower frame is not increased, overflow into the room is effectively prevented, and excellent drainage and watertight performance can be obtained.

  Further, as shown in FIG. 2, in the left half region as viewed from the indoor side where the inner impingement 12b does not exist, the distal end of the airtight member 35a on the outdoor side from the distal end of the indoor airtight member 35b in the inner impeller guide groove 6 The rainwater that is separated downward and flows into the inner guide guide groove 6 from the upper surface of the lower frame auxiliary material 27 falls on the indoor airtight material 35b and then falls on the outdoor airtight material 35a. It falls into the groove and drains from the drain hole 58a at the bottom of the groove. Even if a phenomenon such as water splashing at the bottom of the groove occurs, the kinetic energy is attenuated because the airtight materials 35a and 35b inside and outside must be overcome in a zigzag shape, and even if the surface rises to the upper surface of the lower frame, The kinetic energy that jumps out from there to the indoor space has almost disappeared, and water leakage to the indoor living space can be prevented.

As described above, this sash is provided with the drainage member 3 at the right end as viewed from the indoor side of the lower frame auxiliary member 27, and the drainage member 3 has a drainage channel 7 communicating with the outside from the inner guide groove 6. As a result of the formation, the rainwater that has entered the inner guide groove 6 below the closed inner shroud 12b is drained to the outside without being introduced into the hollow portion of the lower frame 1. There is no need to partition the hollow portion of the lower frame 1 into an outdoor pressure region and an indoor pressure region, and the structure inside the lower frame 1 can be simplified. In connection with this, the number of parts of the lower frame 1 and processing labor can be reduced. In addition, as described above, the rainwater that has entered the inner guide guide groove 6 under the closed inner impeller 12b can be drained to the outside without being introduced into the hollow portion of the lower frame 1, so that the lower frame 1 The hollow portions 59, 29, and 38b can be made to have the same pressure as the indoor side over the entire length in the longitudinal direction, and the water storage portion that stores rainwater and condensed water that has entered these indoor regions beyond the shojis 12a and 12b. Therefore, watertightness and drainage can be improved without increasing the height of the lower frame.
Further, the drainage member 4 is provided at the left end portion of the lower frame auxiliary member 27 as viewed from the indoor side, and the drainage channel 8 is formed in the drainage member 4 so as to communicate with the outside through the outer-slider guide groove 5. Rainwater that has entered the guide groove 5 can be drained smoothly.
Furthermore, since the lower frame auxiliary material 27 placed on the upper surface of the lower frame main body 26 is integrally formed in the prospective direction, this sash greatly reduces the number of parts and reduces costs compared to the conventional lower frame flat sash. I can plan. Since the lower frame auxiliary material 27 can be removed at a time, the maintenance is easy. Further, leakage of water into the lower frame 1 from the joints of the members is prevented, and the watertight performance can be improved. Furthermore, since the lower frame auxiliary material 27 is formed of resin, the entire upper surface of the lower frame 1 is covered with the resin lower frame auxiliary material 27, so that high heat insulation performance can be obtained. Since the airtight lines 72a and 72b are formed between the upper surface of the lower frame 1 and the closed shoji 12a and 12b, the airtightness can be ensured even if the upper surface of the lower frame is substantially flat.
By forming the lower frame 1 with the lower frame main body 26 and the lower frame auxiliary material 27, it is possible to easily form a drain hole 58d for dropping water into the hollow portion 29 of the lower frame main body 26. Processing of the drain holes 58a, 58b, 58c of the lower frame auxiliary material 27 is also easy.
In addition, this sash is provided when the lower frame 1 is looked down from above the indoor side by providing the screen door rail 31 so that the upper end thereof is substantially the same height as or lower than the lower end of the lower frame auxiliary member 27. In addition, the screen door rail 31 is hidden behind the lower frame auxiliary member 27 and is not visible, and the portions other than the pair of grooves 5 and 6 of the lower frame auxiliary member 27 are substantially flat. Can be formed.
Furthermore, since the sash is formed with the shoji guide grooves 5 and 6 in the lower frame auxiliary material 27, the shoji guide grooves 5 and 6 can be simply changed by changing the lower frame auxiliary material 27 while also using the lower frame main body 26. Sashes with different positions and numbers can be formed.

The lower frame auxiliary material 27 can be made of a metal such as aluminum. When the metal lower frame auxiliary material 27 is used, the strength and fire resistance are improved. Even when the metal lower frame auxiliary material 27 is used, as with the resin lower frame auxiliary material 27, the number of parts and processing can be reduced to reduce costs, and cleaning and maintenance are easy. The effect is obtained.
In this sash, the lower frame main body 26 is used in common, and the resin lower frame auxiliary material 27 is selected when the heat insulation performance is important, and the metal lower frame auxiliary material 27 is selected when the cost and fire resistance are important. By doing so, the sash performance can be varied. In the case of a fireproof sash, a metal lower frame auxiliary material 27 is used, and a refractory material that expands due to the heat of the fire in the vicinity of the drain hole and drain hole of the lower frame auxiliary material 27 and the lower frame main body 26. By arranging, the drain hole and the drain hole are closed by the expanded refractory material in the event of a fire, and the spread of fire can be prevented.
