Description

本発明は、網戸に関し、特に、網戸における網を取り付ける構造に関する。 TECHNICAL FIELD The present invention relates to a screen door, and more particularly to a structure for attaching a screen to a screen door.

よく知られている通り、空気の流通、蚊よけ又は室内への汚染物の侵入の防止などの効果を果たすためには、扉や窓に網を取り付け、網により、蚊や汚染物を効果的に遮断できると共に、空気が網における網穴を介して室内と室外を流通できることが一般的である。 As is well known, in order to achieve such effects as air circulation, repelling mosquitoes or preventing the entry of contaminants into the room, a net is installed on the door or window, and the net is used to effectively filter out mosquitoes and contaminants. It is common that air can flow between indoors and outdoors through the mesh holes in the mesh.

よく用いられる網戸は、ネジによる固定やテープによる粘着により網を窓枠に取り付ける方式以外に、押さえゴムにより網の外周縁を窓における取り付け溝に押さえる方式によって、網を取り付け溝と押さえゴムとの間に挟んで、網を窓枠に取り付けるものである。しかしながら、数多くの網は、可撓性を持った素材により生産されたものであることから、網をきれいに拭い、又は、網を予想せぬ押し付ける際に、網を窓枠に固定して接続する箇所が引き伸ばされることにより、変形や破壊が発生し易い。この場合に、網に折り目が生じることにより、美感に影響を与えてしまい、厳重の場合に網もそれにより窓枠から落下して、蚊よけや室内への汚染物の侵入の効果を失うことがある。そして、良く用いられる網戸は、改善すべき余地が存在する。 In addition to fixing the net to the window frame by fixing it with screws or using adhesive tape, commonly used screen doors use a method in which the outer edge of the net is pressed into the installation groove in the window by a pressing rubber. The mesh is attached to the window frame with a sandwich between them. However, many screens are produced from flexible materials, so that when the screen is wiped clean or the screen is pressed unexpectedly, the screen is fixed and connected to the window frame. Deformation and breakage are likely to occur due to the stretching of the portion. In this case, creases in the net affect the aesthetic appearance, and in severe cases, the net also falls from the window frame, losing its effectiveness in repelling mosquitoes and contaminants entering the room. Sometimes. And screen doors that are often used have room for improvement.
