DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for a movable louver window in which a plurality of multi-layer louver blades are vertically rotatably mounted in a frame.

[0002]

2. Description of the Related Art As a movable louver window, for example, the one shown in Japanese Utility Model Publication No. 1-39288 is known. In other words, an upper frame, a lower frame, and left and right vertical frames form a rectangular frame,
A pair of louver blades are connected at intervals in parallel and vertically displaced by clips to form a multi-layer louver blade, and the multi-layer louver blade clip is vertically rotatably connected to a vertical frame to form a plurality of louver blades. A multi-layer louver blade is attached to the frame so as to be rotatable up and down, and a room-side upper lateral airtight material and an outdoor-side upper horizontal air-tight material are mounted on the upper frame, and the indoor louver blade of the uppermost multilayer louver blade is attached to the upper frame. A room-side louver blade of the lowermost multilayer louver blade with a room-side lower horizontal airtight material and an outdoor-side lower horizontal airtight material attached to the lower frame, with the airtightness between the outdoor louver blade and the upper frame, respectively. Airtight between the louver blades and the lower frame on the outdoor side and the lower frame, respectively, and the vertical frame is fitted with a vertical airtight material on the indoor side and an outdoor vertical airtight material so that the clip of each multi-layer louver blade is airtight. It is.

In such a movable louver window, a plurality of indoor louver blades are continuous with each multilayer louver blade closed, and a plurality of outdoor louver blades are continuous. Since an air layer is formed between the louver blades on the outdoor side, the movable louver window has excellent heat insulation.

[0004]

With such a movable louver window, the louver blade and the upper frame on the indoor side of the uppermost multilayer louver blade are water-tight with the indoor-side upper horizontal airtight material, and the louver blade on the outdoor side is closed. The upper frame is watertight with the outdoor upper horizontal airtight material, the indoor and outdoor louver blades of the lowermost multilayer louver blade and the lower frame are airtight with the indoor and outdoor lower horizontal airtight material, and the uppermost multilayer louver. Rainwater does not enter the frame from between the blade and the upper frame, and rainwater does not enter the frame from between the lowermost multi-layer louver blade and the lower frame.

[0005] However, rainwater may intrude from the overlapping portion of the louver blades that are vertically adjacent to each other, and the infiltrated rainwater may collect in the lower frame and flow from the frame to the indoor side due to strong wind and rain.

Accordingly, an object of the present invention is to provide a drainage structure for a movable louver window which can solve the above-mentioned problem.
