Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame structure in an opening frame arranged in an opening such as a window provided in a wall. 2. Description of the Related Art A window, which is an opening provided on a wall surface of a house, is usually a glass shoji supported by a window frame, which is an opening frame.
It is opened and closed by a screen door or the like. Recently, frame materials such as glass screens and screen doors have been made of aluminum profiles, and the frame material forming the periphery of the opening has also been made of aluminum profiles. Has become. A window frame made of an aluminum profile is usually provided with a frame mounting frame that is fitted into an interior frame on the indoor side and attached to the inner surface of the interior frame. The frame mounting frame is formed in a rectangular or square frame shape by a horizontal mounting upper frame portion, a mounting lower frame portion, and vertical left and right mounting vertical frame portions. The upper frame and the lower frame of the frame mounting frame are vertically provided with an upper guide rail and a lower guide rail for supporting a glass sliding door for opening and closing the inside of the frame mounting frame, a screen door, and the like. A glass shoji, a screen door, and the like are slidably supported by the upper guide rail and the lower guide rail. [0003] Since a window frame made of such an aluminum profile is excellent in heat conductivity, the frame mounting frame located in the room is cooled by outdoor cold air. For this reason, there is a problem that dew condensation water adheres to the inner surface of the frame mounting frame. Condensed water adhering to the mounting upper frame portion and each mounting vertical frame portion of the frame mounting frame flows down to the mounting lower frame portion and accumulates on the mounting lower frame portion. For this purpose, a drain port is provided in the lower guide rail portion provided vertically outside the outdoor of the mounting lower frame portion, and the condensed water accumulated on the mounting lower frame portion is drained to the outside through the drain port. That is being done. [0004] A drain port provided in the lower guide rail is usually formed by punching a lower guide rail formed of an aluminum plate. For this reason, the drain outlets are open to the inside and the outside of the room, respectively, and can be easily seen from the room side. As described above, when the drain port provided on the lower guide rail portion is easily viewed from the indoor side, the occupant may have anxiety about the insects entering the room. [0005] In order to solve such a problem, a cover member made of synthetic resin and having a U-shaped groove shape with a downward cross section is disposed on the indoor side of the drain port. In this case, the cover member is provided with an opening that allows the inside of the groove to communicate with the drain port, and the dew condensation water that has entered the inside of the groove from each end opening of the groove provided in the cover member is covered by the cover member. It is discharged through an opening and a drain provided in the member. However, in such a configuration in which the drain port is covered with a specially shaped cover member, a specially shaped cover member must be manufactured, which causes a problem that economic efficiency is impaired. SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to make it easy to see that a drain port is open from the room to the outside without impairing the economy.
