Description

本開示は、内窓に関する。詳しくは、二重窓における外窓の屋内側に配置される内窓に関する。 This disclosure relates to an inner window. More specifically, the present invention relates to an inner window arranged on the indoor side of the outer window in a double-glazed window.

従来、建物の開口部に、内窓と外窓とが二重に設けられて構成される二重窓が知られている（例えば、特許文献１参照）。二重窓は、窓を二重にすることで、断熱性能を高めることができると共に、防音性を高くすることができる。二重窓は、新築時に外窓と内窓とを同時に設けることや、既設の窓の屋内側に、リフォームにより内窓を追加することで設けることもできる。 Conventionally, there is known a double-glazed window in which an inner window and an outer window are doubly provided at an opening of a building (see, for example, Patent Document 1). The double-glazed window can improve the heat insulating performance and the soundproofing property by making the window double. Double-glazed windows can be provided at the same time as an outer window and an inner window at the time of new construction, or by adding an inner window by remodeling to the indoor side of the existing window.

屋内側に配置される内窓は、上枠を有する枠体と、枠体内に配置される障子と、を有する。上枠には、下方に突出する下方突出レールが形成されている。障子の上端部には、上枠の下方突出レールを収容するレール収容ガイドが形成されている。上枠の下方突出レールが、障子のレール収容ガイドに収容されてガイドされることで、障子は、枠体内を見付方向の左右方向にスライド移動可能である。 The inner window arranged on the indoor side has a frame body having an upper frame and a shoji screen arranged in the frame body. The upper frame is formed with a downward projecting rail that projects downward. At the upper end of the shoji, a rail accommodating guide for accommodating the downward protruding rail of the upper frame is formed. The downward protruding rail of the upper frame is accommodated and guided by the rail accommodating guide of the shoji, so that the shoji can slide and move in the left-right direction in the finding direction inside the frame.

特開２０１９－１５２００２号公報Japanese Unexamined Patent Publication No. 2019-152002

内窓は、リフォームにより、既存の窓の内側に追加で取り付ける場合がある。この場合、施工時の調整不足・経年劣化による取付面の変形等により、上枠の下方突出レールと障子のレール収容ガイドとの掛かりが少なくなり、障子が脱落し、内窓の障子が倒れてしまう可能性がある。そのため、内窓の障子の脱落に対する対策が望まれている。 The inner window may be additionally installed inside the existing window by remodeling. In this case, due to insufficient adjustment during construction, deformation of the mounting surface due to deterioration over time, etc., the hook between the lower protruding rail of the upper frame and the rail accommodation guide of the shoji is reduced, the shoji falls off, and the shoji of the inner window collapses. There is a possibility that it will end up. Therefore, it is desired to take measures against the falling off of the shoji screen of the inner window.

本開示は、障子の脱落を防止できる内窓を提供することを目的とする。 The present disclosure is intended to provide an inner window capable of preventing the shoji from falling off.
