Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window for raising and lowering a window, and more particularly to a drainage structure for rainwater and condensed water that collects in the internal space of a crosspiece therein.

[0002]

2. Description of the Related Art In a raising and lowering window, rainwater that enters through the gap between the glass and the beet collects in the inner space of the middle rail which is the lower frame of the stationary shoji located outside the frame. Therefore, in order to discharge the rainwater or the condensed water to the outside, in the conventional raising / lowering window, a drainage port for discharging the rainwater or the like accumulated in the middle rail to the outside is provided in the middle rail.

[0003]

As described above, in the conventional structure in which the drainage port is provided in the middle rail, the outside air communicates with the inner space of the middle rail through the drainage port, and the inner space of the middle rail and the indoor space Communicate with each other through a minute gap between the glass and the beet on the indoor side, so that there is a problem that airtightness and heat insulating property are deteriorated.

In view of the above problems, it is an object of the present invention to provide a raising / lowering window having a structure capable of reducing the deterioration of airtightness and heat insulation due to the drainage portion of the middle rail.

[0005]

According to a first aspect of the present invention, a window frame is composed of left and right vertical frames, an upper frame and a lower frame, and a middle rail is installed between the left and right vertical frames. A movable shoji that constitutes the lower side of the stationary shoji and is vertically movable inside the frame is attached, and at least one end of the internal space of the middle rail is covered with a glass-mounted side cover material of the internal space of the vertical frame or the vertical frame. And a vertical frame are connected to the internal space, and the lower part or the lower frame of the vertical frame is connected to the internal space of the vertical frame or the space between the cover member and the vertical frame. Is provided. The invention according to claim 2 is characterized in that a water-tight valve is provided at the drain port so that water can pass therethrough.

[0006]

According to the present invention, rainwater or dew condensation water that collects in the inner space of the middle rail flows down from the end of the inner space to the inner space of the vertical frame or the inner space between the cover material and the profile, and It flows down to the outside from the drainage port provided in the lower part of the frame or the lower frame. By constructing the flow path for rainwater or the like in this way, the drain port that is directly exposed to the outside, which was provided in the middle crosspiece, can be eliminated, so that the airtight material is improved and the heat insulating property is improved.
In the second aspect of the invention, the drainage port is provided with a valve that allows water to pass therethrough and has airtightness, so that the passage of air is prevented, and thus airtightness and heat insulation are further improved.
