しかし、従来技術は網に特別な加工を実施する必要があり、既存の網戸を有効活用することが困難であり、また、フック面ファスナーおよびループ面ファスナーの２枚の面ファスナーを用いる方法は作業が煩雑でかつ審美性が劣り広く普及するに至っていない。
本発明は、かかる従来技術の問題を解決し、１枚の嵌合可能なフック面ファスナーを用いて網を簡単にかつ強く固定でき、審美性にも優れた網戸を提供するものである。 However, the conventional technique requires special processing for the net, and it is difficult to effectively utilize the existing screen door. Also, the method using two hook and loop hook fasteners is a work. Is inconvenient and inferior in aesthetics, and has not become widespread.
The present invention solves such problems of the prior art, and provides a screen door that can easily and strongly fix a net using a single hook hook-and-loop fastener, and has excellent aesthetics.

即ち本発明は、長手方向に伸びる基板の両縁部に基板から突出する多数のフック状係合素子を有し、基板の中央部が折り曲げ可能なように平坦または凹状であるフック面ファスナーの片端部が網戸枠面に一体化され、該枠面に網を張り合わせてフック状係合素子でその端部を支持し、その状態でフック面ファスナー基板の中央部で折り返して両縁部のフック同士が網を通して嵌合し、網を挟持することによって網を枠面に固定してなる網戸である。 That is, the present invention has one end of a hook hook-and-loop fastener that has a number of hook-like engaging elements protruding from the board at both edges of the board extending in the longitudinal direction and is flat or concave so that the center part of the board can be bent The part is integrated with the screen door frame surface, the net is attached to the frame surface, the end is supported by the hook-like engagement element, and the hooks at both edges are folded back at the center of the hook surface fastener substrate in that state. Is a screen door that is fitted through a net and the net is fixed to the frame surface by sandwiching the net.

これにより、本発明は、１枚の嵌合可能なフック面ファスナーであって、フック面ファスナーを折り返して網を挟むことができるから、網を張り替える作業が容易になる。また、網を簡単にかつ強く固定でき、審美性にも優れている。 Accordingly, the present invention is a hook surface fastener that can be fitted, and the hook surface fastener can be folded back to sandwich the mesh, so that the work of replacing the mesh is facilitated. In addition, the net can be fixed easily and strongly, and it has excellent aesthetics.

図１は網戸１２の全体を示し、図２はフック面ファスナー１及び編み１１の平面を示し、図３は図２の中央部の縦断面を示す。 1 shows the entire screen door 12, FIG. 2 shows a plane of the hook hook-and-loop fastener 1 and the knitting 11, and FIG. 3 shows a longitudinal section of the central portion of FIG.

本発明の網戸１２は＃１８〜＃２４の樹脂製または織り・編み製編みに使用できる。本発明に用いる成形フック面ファスナーの素材はポリエステル、ポリプロピレン、ポリエチレン、ポリアミドなどの樹脂が用いられ、更に、顔料、耐候性向上剤、酸化防止剤、難燃剤、帯電防止剤等を必要に応じて添加することが必要となる。 The screen door 12 of the present invention can be used for # 18 to # 24 resin or weaving / knitting. The material of the molded hook surface fastener used in the present invention is a resin such as polyester, polypropylene, polyethylene, polyamide, and further, a pigment, a weather resistance improver, an antioxidant, a flame retardant, an antistatic agent, etc. as necessary. It is necessary to add.

本発明に用いるフック面ファスナー１は公知の方法、例えば押し出し成形法により基板４に列条突起を立設したテープを製造し、該列条に多数の微小切れ目を付与し、基板４を長さ方向に延伸して、独立した多数のフック状係合素子２を立設したフック面ファスナー１が得られる。フック３及び基板４の形状は押し出しノズルの形状により製造可能である。 The hook hook-and-loop fastener 1 used in the present invention is manufactured by a known method, for example, a tape in which row projections are erected on the substrate 4 by an extrusion molding method. A hook hook-and-loop fastener 1 extending in the direction and provided with a large number of independent hook-like engagement elements 2 is obtained. The shape of the hook 3 and the substrate 4 can be manufactured by the shape of the extrusion nozzle.

本発明において使用されるフック面ファスナー１のフック状係合素子２のフックヘッド部５の形状は「▲型」が良好で、これにより、網１１が刺さりやすく且つ抜け難くなるものである。 The hook head portion 5 of the hook-like engagement element 2 of the hook hook-and-loop fastener 1 used in the present invention has a good “▲” shape, which makes the net 11 easy to pierce and difficult to come off.

また、フックヘッド部５「▲型」の最大幅、つまりフックヘッド部５の斜め下方に延びる２つの押さえフック７の間隔は、網１１の網目の隙間幅より狭いことが必要である。また、フック状係合素子２の基板からフックヘッド部５の下限の押さえフック７までの高さはバリア部６の高さおよび網１１の厚さの合計より大きいことが必要である。 Further, the maximum width of the hook head portion 5 “「 ”, that is, the interval between the two pressing hooks 7 extending obliquely below the hook head portion 5 needs to be narrower than the gap width of the mesh of the mesh 11. Further, the height from the substrate of the hook-like engagement element 2 to the lower limit pressing hook 7 of the hook head portion 5 needs to be larger than the sum of the height of the barrier portion 6 and the thickness of the net 11.

上記バリア部６は、フック状係合素子２のフック支柱部３の下方から側方に延出されている。このバリア部６によって、フック状係合素子２が挿通された網１１が基板４から浮いた状態にされる。この結果、フックヘッド部５及び押さえフック７が網１１の網目を貫通し易くなる。 The barrier section 6 extends laterally from below the hook support section 3 of the hook-like engagement element 2. By this barrier portion 6, the net 11 through which the hook-like engagement element 2 is inserted is brought into a state of floating from the substrate 4. As a result, the hook head portion 5 and the holding hook 7 can easily penetrate the mesh of the mesh 11.

さらに、フック状係合素子２の列間距離はフックヘッド部５の最大幅の２倍以上で、フック状係合素子２が密度１０〜１００本／cm２で立設されていることが必要である。これにより、フック面ファスナー１の両縁部のフック状係合素子２同士が、基板４の折り返し部８で折られて幅方向に重ねられ、フック状係合素子２が網１１を両側から挿通して嵌合され、網１１の所定の挟持力が得られる。フック状係合素子２の列間距離はフックヘッド部５の最大幅の２〜２．５倍が好ましく、フック状係合素子２の密度は２０〜６０本／cm２が好ましい。 Further, the distance between the rows of the hook-shaped engagement elements 2 is required to be more than twice the maximum width of the hook head portion 5 and the hook-shaped engagement elements 2 are erected at a density of 10 to 100 / cm2. is there. As a result, the hook-like engagement elements 2 at both edges of the hook surface fastener 1 are folded at the folded portion 8 of the substrate 4 and overlapped in the width direction, and the hook-like engagement element 2 is inserted through the net 11 from both sides. And a predetermined clamping force of the net 11 is obtained. The distance between the rows of the hook-like engaging elements 2 is preferably 2 to 2.5 times the maximum width of the hook head portion 5, and the density of the hook-like engaging elements 2 is preferably 20 to 60 / cm2.

また、本発明のフック面ファスナー１は幅方向中央部で折り返すため、中央部に平坦部または凹状部をフック列２列以上のスペース分介在させることが必要である。また、折り曲げ易くするため、樹脂素材は撓み易い素材を選び、中央部の厚さは０．５mm以下が必要である。両縁部のフック列は２列以上が必要でこれにより、所定の網の挟持力を得るものである。 Further, since the hook surface fastener 1 of the present invention is folded back at the central portion in the width direction, it is necessary to interpose a flat portion or a concave portion in the central portion by a space of two or more hook rows. In order to make it easy to bend, a resin material that is easy to bend is selected, and the thickness of the central portion needs to be 0.5 mm or less. Two or more hook rows at both edge portions are required, thereby obtaining a predetermined mesh clamping force.

尚、本発明のフック面ファスナー１は幅方向片面部を網戸１２の枠に粘着剤等で固定する。更に必要に応じ、ビスで補強することも可能である。また、網はその端部を幅方向中央部で揃えることが挟持作業を容易にさせ、かつ、所定の網の挟持力を得るうえでも有効である。 In the hook surface fastener 1 of the present invention, one side in the width direction is fixed to the frame of the screen door 12 with an adhesive or the like. Furthermore, if necessary, it can be reinforced with screws. Further, aligning the end of the net at the center in the width direction is effective in facilitating the clamping work and obtaining a predetermined net clamping force.
