Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sash having a water collecting port on the upper surface of a lower frame.

[0002]

2. Description of the Related Art In many cases, a lower frame of a sash has a hollow structure from the viewpoint of strength. In addition, since rainwater and dew condensation water easily accumulate on the upper surface of the lower frame, the lower frame substrate (upper wall)
A water collection port is formed by communicating with a hollow portion below the water hole, and rainwater or the like guided to the hollow portion is discharged to the outside through a drain port provided on a front wall of the hollow portion. However, in this configuration, when the rain wind is strong, the air pressure in the hollow portion is increased by the strong wind, and the air blows out from the water collecting port of the lower frame to the indoor side. For this reason, the rainwater moving on the upper surface of the lower frame may splash at the location of the water collecting opening and scatter into the room.

[0003] Among sashes provided with sliding sliding doors, the rising rail provided on the upper surface of the lower frame and the indoor rising wall have substantially the same height so that the sliding door can be easily attached and detached from the indoor side. In this case, rainwater easily accumulates between the rails or between the rail and the indoor rising wall. Rather, in the sash having this structure, rainwater is positively stored between the rails or between the rails and the rising wall, and the rainwater pressure and the sealing function are used. That is, the pressure of the rainwater stored on the indoor side acts between the lower frame of the shoji and the rail, thereby preventing wind and rain from blowing more than that. A groove structure in which rainwater or dew condensation water easily accumulates, such as between rails, between a rail and a room-side rising wall, or between a fitted outer sash and an indoor-side rising wall, etc. In the case of having, the splash is liable to be scattered due to the blowing from the water collecting port.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sash which does not blow out from a water collecting port provided in a lower frame.

[0005]

A sash having a sash frame and a shoji is provided. The sliding doors are mainly sliding doors such as single sliding sliding doors and sliding sliding doors, but may also be three- or four-sheet sliding doors or rotary sliding doors. In addition, sashes are not only windows, but also door sashes. The lower frame of the sash frame is
This is an extruded product of an aluminum alloy having a hollow portion in cross section, and has an upper substrate provided with rails and the like and a hollow portion therebelow.

[0006] A water collecting port communicating with the hollow portion is provided on the substrate, a drain port for discharging rainwater or the like is provided in the hollow portion, and the hollow portion is communicated with the indoor space. There are various means for communicating the hollow portion with the indoor space, but the hollow portion of the lower frame is communicated with the hollow portion of the vertical frame from the hole provided at the lower portion of the vertical frame, and the upper portion of the vertical frame is communicated with the indoor space. Providing an air vent hole is one of them. A drain valve may be installed at the drain port. With this structure, even if the air pressure in the hollow portion increases during a strong wind, the air pressure can be immediately released to the indoor space, so that there is no blowout from the water collecting port provided in the lower frame substrate.

The following configuration may be adopted. An exhaust port is provided separately from the water collecting port on the indoor side portion of the lower frame substrate, and the exhaust port is isolated from rainwater moving on the upper surface of the lower frame substrate. There are various isolation means, such as storing around the exhaust port, increasing the depth of moving rainwater or the height of water droplets, and providing an isolation wall across the sump.
A cover attached to the exhaust port is also one of the isolation means, and prevents rainwater from inadvertently entering the vicinity of the exhaust port on the peripheral wall of the cover.

The inside of the cover needs to communicate with the indoor space. The hollow portion of the cover communicates with the hollow portion of the vertical frame, and the cover located in the indoor space has an air vent hole at the top. Further, the cover may be developed so that a sliding door stopper, which is usually disposed on a sliding door such as a sliding sliding door or a single sliding door, may be used as the cover. In this case, the shoji stopper has a hollow structure, and an air vent hole is provided in the upper part. According to this configuration, the processing of providing the same exhaust port as the water collecting port may be performed on the substrate of the lower frame, so that the labor and cost for processing the vertical frame or other members can be reduced.

[0009]

1 and 2, a sash 1 is for a semi-external type window, and includes a sash frame 2 and a sliding door 3. FIG. The sash frame 2 has a normal configuration in which an upper frame 4, a lower frame 5, and left and right vertical frames 6, 7 are assembled in a rectangular shape. Each frame material is an extruded aluminum alloy material. The sliding door 3 is a sliding shoji, and is composed of an outer shoji 3a and an inner shoji 3b. Reference numeral 8 denotes a screen door, which is disposed on the outermost side.
The lower frame 5 of the sash frame 2 is obtained by cutting a profile having a hollow portion 9, and includes a substrate 10 serving as an upper wall, an outer rail 11 and an inner rail 12 that are formed by rising upward from the upper surface, and the indoor side. Is provided with a rising wall 13 at the edge of the frame. As shown in FIG. 1, these rails 11 and 12 and the rising wall 1 on the indoor side are used.
3 are almost the same height, the outer rail 11 and the inner rail 1
2 and the indoor-side rising wall 13 are arranged at intervals in the indoor and outdoor directions, so that a space between them and the substrate 10 is a reservoir groove. In addition, a water collecting port 14 is provided at a location corresponding to the upper part of the hollow portion 9 of the substrate 10, and a drain valve 15 is attached as a drain port at several places on the front wall of the hollow portion 9.

The outer sash 3a and the inner sash 3b have almost the same ordinary structure, and include an upper frame 16, a lower frame 17 and left and right vertical frames 18, 19.
Are assembled in a rectangular shape, and the glass 20 is attached thereto. Right vertical frame 19a of outer shoji 3a and left vertical frame 1 of inner shoji 3b
8b is a combination frame, and the other vertical frames are door-stop frames.
On the left side surface of the assembling frame 3b of the inner shoji 3b, there is an overhang portion 21 such as a crescent or a lock mechanism (FIG. 2). The upper frames 16a, 16b of the outer sash 3a and the inner sash 3b are in contact with the guide fins 22 provided on the upper frame 4 from both inside and outside of the room by watertight materials 23, and the lower frames 17a, 17b are provided with watertight materials 24 from the outside.
To contact the outer rail 11 and the inner rail 12 (FIG. 1). Furthermore, the door stop side vertical frames 18a and 19b are in contact with the airtight fins 26 provided on the vertical frames 6 and 7 from outside by a watertight material 25, and the combination frames 19a and 18b generate wind when the sliding door 3 is closed. They come into contact with each other via the watertight material 27 at the barbs.

In FIG. 2, reference numeral 28 denotes a shoji stopper, which is a hollow synthetic resin molded product, the lower surface of which is opened (FIG. 4), and an air vent hole 29 is formed in the upper corner. The shoji stopper 28 is attached to the left vertical frame 6 on the substrate 10 of the lower frame 5. Further, two exhaust ports 30 are formed side by side in the lower frame 5 near the left vertical frame 6 of the substrate 10, that is, in the area of the shoji stopper 28. Therefore, the hollow portion 9 of the lower frame 5 communicates with the indoor space through the exhaust port 30 and the air vent hole 29.

The right and left dimensions of the shoji stopper 28 are slightly larger than the overhang dimensions of the crescent and the like provided in the inner shoji 3b, and the width extends between the outer rail 11 and the inner rail 12. The shoji stopper 28 is mounted on the substrate 10.
Are mounted using rails 11 and 12 (FIG. 3), and a groove 31 (FIG. 4) that sandwiches the inner rail 12 is formed from the side surface to the lower surface side of the shoji stopper 28. Further, the front edge of the shoji stopper 28 is
At the top, abutment is made on the lower surface of the portion 32 projecting to the indoor side, so that the shoji stopper 28 does not float upward.

When the sliding door 3 is closed, the watertight materials 23 to 25 of the frames constituting the outer sash 3a and the inner sash 3b contact the outer surfaces of the corresponding rails. 27, the watertight surface A-
B, BC and CD are formed, and the interior and exterior can be partitioned airtight and watertight for the time being. The shoji stopper 28 is a watertight surface.
The air vent hole 29 is located closer to the indoor side than the AD, and the air vent hole 29 opens to the indoor side space.

In the case of ordinary wind and rain, the watertight function of the watertight material disposed on the watertight surface AD can sufficiently maintain the airtight watertightness. However, for some reason, as shown in FIG. It invades the inside and accumulates in a reservoir groove 33 formed by the outer rail 11 and the inner rail 12 or the indoor-side rising wall 13 and the substrate 10. Alternatively, the dew water is stored in the reservoir groove 33. The water enters the hollow portion 9 below the substrate 10 from the water collecting port 14 and is discharged to the outside via the drain valve 15. At this time, even if the air pressure in the hollow portion 9 increases due to the wind pressure or the external air pressure, the air pressure escapes from the separately provided exhaust port 30 to the indoor side through the shoji stopper 28, so that the water collection port 1
There is no possibility that the wind blows up from 4 and the water accumulated in the reservoir groove 33 is splashed and scattered to the indoor side. In addition, the exhaust port 30 is surrounded by the shoji stopper 28, is temporarily partitioned from the reservoir groove 33, and is isolated from rainwater moving on the upper surface of the lower frame.

In this embodiment, the drainage valve 15 for discharging rainwater guided to the hollow portion 9 is closed in a strong wind direction because the drainage valve 15 discharges rainwater guided to the hollow portion 9 because the sash uses the water pressure and sealing function of rainwater. It operates, and the watertight surface A-
Since the rainwater that breaks through D is positively stored, the hollow portion 9 below the substrate 10 is filled with rainwater that cannot be completely drained as shown in FIG. Accumulate. And the lower frame 17 of the outer sash 3a and the inner sash 3b
The lower edges of a and 17b sink below the surface of the stored water.
Such rainwater also accumulates on the indoor side of the seal block located at the lower part of the assembling portion. In this case, the water pressure of the accumulated water acts on the gap between the lower edges of the lower frames 17a and 17b and the substrate 10 to oppose the wind pressure, so that when the accumulated water increases to a certain extent, further infiltration of rainwater is suppressed. In addition, since there is a sealing function using water, high watertightness and airtightness are maintained even in a strong wind. The same is true of the seal block, and the rainwater blown from the outside of the block is pushed by the water pressure on the indoor side and cannot enter the indoor side. In addition, since the air vent hole 29 of the shoji stopper 28 is arranged higher than the top of the rail that constitutes the reservoir groove 33, the function of air vent is not impaired.

The above is an example of the embodiment.
The cover that covers the exhaust port 14 provided is not limited to the shoji stopper 28, but may be any cover in general. Further, the air vent hole 29 may be provided in the vertical frame at a position higher than the reservoir groove 33 so as to communicate with the space inside the cover. Although the sash of the reservoir type has been described, the present invention relates to a lower frame having a hollow portion, wherein a water collecting port is provided in a substrate which is an upper wall of the hollow portion, and rainwater on the upper surface of the lower frame is guided from the water collecting port to the hollow portion. It can be generally applied to a sash having a structure for discharging.

[0017]

According to the first aspect of the present invention, since the hollow portion of the lower frame provided with the water collecting port is communicated with the indoor space, there is no blowout from the water collecting port even in strong wind and rain. Is not scattered indoors. According to the configuration of the second aspect, the hollow portion of the lower frame can be communicated with the indoor space with a simple configuration in which the substrate is provided with the water collecting port and the exhaust port. According to the configuration of the third aspect, the configuration as the isolation means is simple, and when the air pressure in the hollow portion is released, the force of the air blown out from the exhaust port is weakened, the curtain shakes, and the blowing sound is generated. Inconvenience can be prevented.
According to the configuration of the fourth aspect, since the air vent hole is provided directly in the cover, the structure is simpler and the manufacturing cost is lower than in the case where the exhaust port is communicated with the indoor space using the hollow portion of the vertical frame. According to the configuration of the fifth aspect, by using the shoji stopper, in the case of the sliding door, no additional member is required to keep the exhaust port isolated from rainwater, and the number of parts does not increase. Further, since the shoji stopper is a component normally provided in the sliding shoji, the existence of the exhaust port is inconspicuous. According to the configuration described in claim 6, in a pool type sash in which rainwater is easily stored, it is possible to eliminate blowout from the water collecting port and prevent generation of splash.
