Description

The present invention relates to a waterproof structure for a summing portion of a double door, and more particularly to a waterproof structure for a lower portion of the summing portion.

In a door device that requires airtightness or watertightness, the door frame is provided with airtight members or watertight members in a quadruple shape, and when the opening is closed, the four peripheral edges on the indoor side of the door body press the airtight members or watertight members. In this way, airtightness or watertightness is ensured. In double doors in which the door side parts of the two door bodies form a summing portion when the opening is closed, the support portion (groove or pocket is formed) protruding from one door body is airtight for the summing portion. A member or a watertight member is provided, and the door side portion of the other door body is in close contact with the airtight member or the watertight member when the opening is closed, so that the airtightness or watertightness of the summoning portion is ensured ( Patent Documents 1 to 5).

When watertight performance is required for the double doors, in particular, if a slight gap is formed at the lower part of the summoning section, there is a risk that water will enter the building due to water leakage from the gap. Therefore, it is important how to prevent water leakage in the lower part of the summoning section in a double door that requires watertight performance. In the above Patent Documents 1 to 5, an airtight structure or a watertight structure of the lower part of the summoning part is disclosed, respectively, but how to improve the waterproof performance of the lower part of the summoning part depends on the structure of the summoning part. There are various approaches.

The inventors have provided a lower part of the watertight member for the summoning section and a first door body provided with the watertight member for the summoning section (the second door that is in close contact with the watertight member for the summoning section when the opening is closed). I thought about improving the waterproof performance of the lower part of the summoning section by paying attention to the water tightness with the lower part of the body (not the body).
