Description

  The present invention relates to a lateral tight material that closes a gap between a lateral frame of a sash window and a shoji screen.

  In the sliding sashes, tight materials are provided between the inside and outside shoji summons, between the shovel and the shoji door toe, and between the shovel and shoji. We are trying to improve. As described in Patent Document 1, the horizontal tight material provided in the horizontal frame includes a base portion attached to a groove-like tight material holder provided in the horizontal frame, and a kamaboko-shaped hollow shape provided on the outdoor side of the base portion. A seal portion is provided, and when the shoji is closed, the hollow seal portion is crushed and comes into surface contact with the side surface of the shoji room.

In the conventional transverse tight material, if the amount of deformation of the hollow seal portion is set large, the hollow seal portion is strongly pressed against the side surface of the shoji room to improve the airtightness and sound insulation, Since the friction between the hollow seal portion and the side of the shoji room increases, there is a disadvantage that opening and closing of the shoji becomes heavy. In addition, if the tight material is hard and the deformation amount is small, the tight material may be loosely or tightly touched due to the slippage of the shoji, and the performance such as airtightness becomes unstable. Further, in the conventional horizontal tight material, since the lower surface of the hollow seal portion is straight and the indoor side end portion is in contact with the tight material holder of the horizontal frame, water droplets adhering to the shoji cover the lower surface of the hollow seal portion. As a result, the inside of the tight material holder in the horizontal frame oozed out, and water overflowed from the tight material holder to the indoor side.
JP-A-8-151869

  In view of the circumstances described above, the present invention can stably ensure high airtightness, reduce the opening / closing force of the shoji, and water droplets attached to the shoji cover the lower surface of the hollow seal portion. An object is to provide a transverse tight material that can prevent the inside of the tight material holder of the lateral frame from seeping.

  In order to achieve the above object, the transverse tight material according to the invention described in claim 1 includes a base portion fixed to the lateral surface of the lateral frame chamber, and a hollow seal portion provided on the outdoor side of the base portion. A wrinkle tight material abutting wall that protrudes substantially horizontally from the base and abuts the end face of the wrinkle tight material fixed to the wrinkle frame, and protrudes inclined from the base in a direction away from the horizontal frame expected surface and the horizontal frame expected surface A wall-facing surface facing wall facing each other at intervals, an outdoor wall that connects the heel tight material abutting wall and the wall-facing surface facing wall, and has a substantially central portion in the vertical direction bulging outward. Grooves are provided in the longitudinal direction at approximately the center in the vertical direction of the inner wall, the inner wall at the corner of the outdoor wall and the heel tight material abutting wall, and the inner wall at the corner of the outer wall and the opposite side of the lateral frame prospective wall.

By providing a groove in the longitudinal direction on the inner wall at the corner of the face-facing wall, the vertical center of the outdoor wall becomes a trough when it is pressed against the shojibu, and it is elastically deformed flexibly and greatly. The gap between the horizontal frame and the shojibu can be reliably sealed, and the valley is in non-contact with the shojibu and close to the base, so the friction with the shojibu is reduced and the shoji The opening and closing force can be reduced. In addition, since the wall-facing surface facing wall of the hollow seal portion is inclined in a direction away from the base frame-facing surface from the base, water droplets can easily flow down the wall-facing surface facing wall. It is difficult for water to soak into. Further, the lateral tight material of the present invention has an abutment tight material abutting wall that protrudes substantially horizontally from the base portion, and even when the hollow seal portion is crushed by being pressed against the shoji lie, the abutment tight material abutment wall Is maintained in a substantially horizontal state, so that rainwater can be prevented from entering the indoor side from the abutting portion with the kite tight material.

  Furthermore, the lateral tight material according to the invention of claim 2 has a draining portion below the base of the lateral frame prospective surface facing wall of the base, so that water drops connecting the lateral frame prospective surface facing wall are eliminated at the draining portion. Thus, it is possible to more reliably prevent water from seeping into the tight material holder.
