Description

  The present invention relates to a sash having a drainer attached to the lower surface of a lower frame.

  In the conventional sash, in order to prevent the dirty rainwater flowing down from the sash frame from being applied to the outer wall and contaminating the outer wall, a drainer may be attached below the lower frame. As shown in FIG. 10, the conventional drainer 90 is screwed and attached to the outdoor side surface of the housing 92 with a space from the lower surface 91a of the lower frame 91 (see, for example, Non-Patent Document 1). As shown by an arrow 93 in the figure, when there is a strong rain wind, there is an inconvenience that rainwater enters the casing 92 through the upper surface of the drainer 90.

As another conventional example, there is one in which a drainer 90 is attached to the lower surface 91a of the lower frame 91 as shown in FIG. The drainer 90 has a hollow plate-like main body 90a and a contact portion 90b extending stepwise from the indoor side end of the main body to the indoor side, and has a bowl-shaped engagement protruding from the upper surface of the main body. The stop piece 90c is hooked on the outdoor side end portion 91b of the lower frame, and the upper surface of the contact portion 90b and the lower surface of the lower frame 91a are adhered and attached with a double-sided tape 94. The drainer 90 is attached by attaching a double-sided tape 94 to the upper surface of the abutting portion 90b in advance and attaching the locking piece 90c to the outdoor end of the lower frame in a state where the drainer is inclined as indicated by a virtual line in the figure. It is hooked on the portion 91b, and the drainer is rotated so that the abutting portion 90b is lifted with the locking portion as a fulcrum, and the double-sided tape 94 is pressure-bonded to the lower frame lower surface 91a. Since this drainer has only one locking portion with the lower frame, the mounting state is very unstable, so that the double-sided tape 94 is peeled off and a gap is formed between the lower frame lower surface 91a and the upper surface of the contact portion 90b. There is a high risk of opening. Further, since the contact portion 90b extends to the frame fixing piece 91c of the lower frame, as shown in the arrow 93 in the figure, when rainwater enters the gap between the upper surface of the contact portion 90b and the lower frame lower surface 91a, the rainwater 94 is There is a risk of entering the housing 92. Furthermore, when attaching a drainer to the lower frame of the continuous window, it is necessary to cut out the lower part of the vertical from the abutting part 90b to the upper surface of the main body part 90a, but the cross-sectional strength is reduced by the notch. For this reason, the drainage bends at the notched portion.
