Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sash drainage device.

[0002]

[Prior Art]

 For example, as disclosed in Japanese Utility Model Laid-Open No. 62-40192, a through hole communicating with the outside is provided in the horizontal part of the sash lower frame, and a draining block is fitted in the through hole to attach the water to the horizontal part. A drainage channel for the condensed water that has accumulated in the drainage channel is installed vertically, and a spherical valve element that connects and disconnects the valve seat provided in the drainage channel is housed in the drainage channel. Some of them have a structure that projects below the drainage channel.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional structure, the valve body is brought into contact with the valve seat by wind pressure to prevent the invasion of wind into the room, but since the valve body is spherical, the valve body moves toward the valve seat due to wind pressure. Is not always smooth. In addition, when draining water, the dew condensation water is drained through a small gap between the valve body and the water draining block, so that the gap easily clogs and drainage operation cannot always be performed smoothly. There is.

The present invention has been devised for the purpose of eliminating such drawbacks of the conventional example and providing a drainage device for a sash capable of smoothly performing drainage and rain operation for windbreaks.

[0005]

[Means for Solving the Problems]

 A through hole communicating with the outside is provided in the horizontal part of the sash lower frame, and a drainage block is fitted in the through hole to vertically install a drainage channel for the condensed water that has accumulated on the horizontal part. A guide cylinder supported by arm pieces projecting in the drainage direction from the water draining block is provided in the passage, and a plate-shaped valve element is provided at the lower end of a rod rod supported by the guide cylinder in a vertically movable manner. A valve seat for contacting / separating the valve body is provided at an intermediate portion in the vertical direction of the drainage channel.

【Example】

 The drawings show one embodiment of the sash drainage device according to the present invention. FIG. 1 is a vertical cross-sectional view showing a part of the sash drainage operation omitted, and FIG. FIG. 3 is a vertical sectional view, FIG. 3 is a perspective view of the drainage material, FIG. 4 is a vertical sectional view of the same, and FIG.

The drainage device of the present invention is configured by providing a horizontal hole 1a of the sash lower frame 1 with a through hole 2 communicating with the outside and attaching a drainage material A to the through hole 2.

The drainage material A is composed of a water draining block 3 and a valve body 4 attached to the water draining block 3, and the water draining block 3 has a small diameter upper drainage channel 5a and a large diameter lower drainage channel 5b. A cylindrical body having a drainage channel 5 communicating with the above is penetrated through the through hole 2, and a locking collar 6 provided at the upper end is locked at an edge portion and fitted into the through hole 2. A guide tube 7 is supported on the lower part of the upper drainage channel 5a by four arm pieces 10, 10, 10, 10 protruding from the drainage block 3 in the direction of the drainage channel 5 and guided by the guide tube 7. A circular plate-shaped valve body 4 is provided at the lower end of a rod rod 8 which penetrates a cylinder 7 and is supported so as to be vertically movable, and a valve seat 9 with which the valve body 4 comes into contact with and separates from the upper drainage channel 5a. It is provided at the top.

Therefore, as shown in FIG. 1, the valve body 4 is separated from the valve seat 9 due to the weight of the valve body 4 or the load of the condensed water, and the condensed water accumulated on the horizontal piece 1 a is drained. Is drained to the outside world.

Further, under strong wind, the valve body 4 is pushed up by the wind pressure, the valve body 4 comes into contact with the valve seat 9 to close the drainage channel 5, and the invasion of wind into the room is prevented.

FIG. 11 shows a reinforcing ridge.

[0012]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the valve body can easily come into contact with the valve seat due to wind pressure to prevent wind from entering the room, and there is a risk of clogging. It is possible to provide a sash drainage device that can smoothly drain dew condensation water.
