BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for a sliding sash in which an inner sash and an outer sash are mounted in a window frame.

[0002]

2. Description of the Related Art In general, pulling sashes are often provided with a space between an outer rail and an inner rail of a lower frame of a shoji and a shoji dropped between the inner and outer rails. ing. However, since water accumulates between the inner and outer rails, a drainage device is provided.

Usually, such a drainage device is such that a drainage block having a drainage plate which can be opened only to the outside is fitted into an opening provided in a lower frame of a window frame. According to such a drainage device, the distance between the inner and outer rails can be increased,
The shoji can be removed from the indoor side.

[0004] As this type of drainage device, for example, a drainage block is fitted into an opening between an outer rail and an inner rail of a lower frame of a sash, as disclosed in Japanese Patent Application No. 5-28041. In some cases, the drainage block can be removed from the opening by fixing the upper and lower elastic pieces with the retaining piece at the upper end and releasing the elastic piece. Since such a drain block is used, it is possible to obtain a drain device in which the drain block is firmly fixed and which can be easily removed.

[0005]

By the way, as described above, the drain block having the drain plate which can be opened only to the outside opens the drain plate by the weight of the water accumulated in the block, and the drain block is opened from the drain port to the outside of the room. The system is designed to discharge water to avoid water accumulation in the rails.

However, the drain plate of this drain block does not have a regulating means for regulating the opening amount during the entire opening process of the drain plate. Had. When an external force is applied to the drainage device due to strong wind or rain, the drainage plate may be opened more than the opening required for drainage. Further, a sound may be generated when the drainage plate is opened and closed.

[0007] For this reason, in the past, in the case of strong wind and rain, the drainage plate was opened more than the opening required for drainage due to wind pressure, and rainwater sometimes entered from the drain outlet. In addition, the higher the wind pressure applied to the drainage device, the more the drainage plate is opened and the drainage plate cannot be closed. As described above, the more the drainage plate is opened, the easier it is to infiltrate rainwater from the drainage port, and the greater the noise generated when the drainage plate is opened and closed. Furthermore, when the amount of water that intrudes increases, a situation occurs in which water accumulates in the rail.

Therefore, the present invention solves such a problem when the external force is applied to the drainage device due to strong wind and rain.
It is an object of the present invention to provide a drainage device that prevents rainwater from entering through a drain port even when the drainage plate is opened and suppresses the volume of sound generated when the drainage plate is opened and closed.

A sash drainage device characterized in that:

As described above, according to the drain device for a sash of the present invention, the opening amount regulating means is provided in the middle of the entire opening process of the drain plate, so that the opening amount of the drain plate can be suppressed. That is, it is possible to set the limit amount of opening of the drain plate small.

As described above, in the related art, particularly in the case of strong wind and rain, the drainage plate is opened more than the amount required for drainage due to wind pressure, so that rainwater may enter from the drainage port, or the drainage device may be damaged. As the wind pressure increases, the drainage plate opens greatly and the drainage plate may not close, or the sound generated when the drainage plate opens and closes may increase, or if the amount of water that intrudes increases. , Water had accumulated in the rails, but in the present invention,
Since the regulating means is provided in the middle of the process of fully opening the drainage plate, the amount of opening of the drainage plate can be suppressed, and rainwater can be prevented from entering. Further, the volume of the sound generated when the drainage plate is opened and closed can be suppressed. Even if the drainage plate is opened, the limit amount of opening of the drainage plate is set small, so that rainwater does not easily enter and a small amount of rainwater enters. Therefore, it is possible to avoid a situation in which the infiltrated rainwater accumulates in the rail.

According to a second aspect of the present invention, in the first aspect, the regulating means contacts at least one of the drainage plate and the attachment portion of the drainage block with the attachment portion or the drainage plate. This is a sash drainage device provided with a projection.

As described above, according to the sash drainage device of the present invention, at least one of the drainage plate and the mounting portion of the drainage block is provided with the projection that comes into contact with the mounting portion or the drainage plate. Can be easily regulated.
