BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for an upper frame in a vertical axis rotating window sash in which a shoji is rotatable around a rotating shaft provided near the center of an upper / lower frame and an upper / lower frame. It is a thing.

[0002]

2. Description of the Related Art A vertical shaft rotating window sash has an upper frame provided with a mounting seat for supporting a rotary shaft. The rotary shaft is inserted into a shaft mounting hole formed in the sash, and the rotary shaft is inserted through the rotary shaft. It supported the shoji on the upper frame so that it could rotate. There is no water draining structure in the upper frame of such vertical shaft rotating window sash, and when rainwater enters the upper frame hollow part from the shaft mounting hole, this rainwater is not drained and stays in the hollow part. It was supposed to do.

[0003]

Since the upper frame of the conventional vertical axis window sash is not provided with the drainage structure as described above, the rainwater that has infiltrated the hollow portion is retained inside. It was This adversely affects the seal, corrodes the sash material, and shortens the sash life. Also, it was a cause of water leakage from the screw holes to the inside of the room. The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to obtain an upper frame drainage structure for a vertical rotary window sash that can drain rainwater that has entered the hollow part of the upper frame to the outside. It is intended.

[0004]

In order to solve the above-mentioned problems, the upper frame drainage structure of the vertical axis rotating window sash according to the present invention is a rotation provided near the center of the upper and lower frames and the upper and lower frames. In a vertical axis rotating window sash capable of rotating a shoji about an axis, a water receiver is installed in the hollow part of the upper frame below the shaft mounting hole of the rotary shaft, and a backup material outside the hollow part is provided. It is characterized in that a drain hole is provided at a higher position for draining rainwater that has infiltrated on the water receiver to the outside of the hollow part chamber.

[0005]

Since the upper frame water drainage hole structure of the vertical shaft rotating window sash according to the present invention is constructed as described above, when rainwater penetrates into the hollow portion from the rotary shaft mounting hole of the upper frame, this rainwater is After falling onto a water receiver located below the mounting hole, it is received and drained to the upper space of the backup material on the outside of the hollow part outside the hollow part through the water drain hole, and then to the outside through the inner space of the outdoor vertical frame and lower frame. Is discharged. Therefore, the rainwater that has entered the upper frame hollow portion does not stay.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention is shown in FIGS. A sash upper frame 1 is rotatably supported near the center of an upper frame 3 of a shoji through a rotary shaft 2 near the center thereof. The upper frame 3 is provided with a shaft mounting seat 4, a shaft mounting hole 5 and a rotary shaft 2 inserted therein. Further, in the hollow portion of the upper frame 3, a water receiver 6 made of sponge rubber, which is waterproof, is installed below the shaft mounting hole 5. The water receiver 6 has a structure in which three sides are surrounded by flanges, and the bottom surface is inclined toward the open side without flanges. The water receiver 6 has a dimension A that is the same as the length of the shaft mounting seat 4 and is provided on the wall surface outside the hollow portion. The dimension B has the same height as the lower end height of the drain hole 7.

The water drainage hole 7 is opened on the wall surface outside the hollow portion room so as to communicate with the upper space at a position higher than the seal material 9 holding the glass 8 and the backup material 10 on the outside of the hollow frame room of the upper frame. The rainwater that has dropped onto 6 is drained to the upper space of the backup material 10 outside the hollow portion room. The height position of the backup material 10 is restricted by the protrusion 11. In addition, the upper space of the back-up material 10 on the outer side of the hollow part outside of the upper frame communicates with the space inside the lower frame through the space inside the vertical frame, and is connected to the outside through the hole provided on the outside wall surface of the lower frame. ing.

In the above structure, however, when rainwater infiltrates into the hollow portion of the upper frame 3 from the shaft mounting hole 5 of the rotary shaft 2, the rainwater is entirely contained in the water receiver 6 located below the shaft mounting hole 5. It falls, flows to the drain hole 7 by the inclined surface of its bottom surface, is discharged to the outside of the hollow part chamber, and is further discharged to the outside through the vertical frame and the lower frame. Therefore, the rainwater that has entered the upper frame hollow portion will not be drained to the same portion and will not accumulate.

[0009]

As described above, according to the vertical frame rotating window sash upper frame drainage structure according to the present invention, rainwater that has entered the upper frame hollow portion can be drained to the outside without delay. It is possible to prevent water leakage into the room from holes, etc., deterioration of the sealing material, and corrosion of the sash material.
As a result, the sash's life can be extended and other great effects can be obtained.
