Description

【0001】
【発明の属する技術分野】
本発明は、建物開口部に防虫のために取り付けられ、アコーディオン式に伸縮自在のネットを横引きにより開閉自在とした網戸に関するものである。
【0002】
【従来の技術】
従来から、図3に示すような網戸、即ち、多数の平行で等間隔な折曲部において交互に逆方向に折曲することによりアコーディオン式に伸縮自在としたネット32を、枠体31内において横引き式に開閉自在とした横引き式網戸は、極めて一般的に知られている。この横引き式網戸においては、上記ネット32の一端を上記枠体31の一方の縦枠部材31aに固定すると共に、該ネット32の他端を上記枠体31の上下の横枠部材31c,31dに沿って摺動する開閉操作用の操作框33に取り付け、また、ネット32の上下端を横枠部材31c,31dに嵌入した状態でガイドさせ、それによって該ネット32を開閉自在にしている。
【0003】
上記横引き式網戸において、図3に例示しているように、操作框33に一端を固定したワイヤ34a〜34dを上記ネット32中に水平に挿通したうえで、上記縦枠部材31aに設けたガイド部材35を介して該縦枠部材中に垂下させ、該縦枠部材31a中においてそれらのワイヤの先端に重り36を吊下しておくと、ネット32が張設状態にあるときに操作框33が当接している縦枠部材31bと該操作框33との間に設けた掛け金具37を外したとき、該張設状態にあるネット32を上記重り36の作用により自動的に折り畳み、建物開口部を自動開放することができる。
【0004】
しかるに、通常、上記ネット32が張設状態にあるときの上記重り36とその上昇限となる当接部38との間にある程度の間隔dが生じるようにワイヤ長を設定し、建物開口部への枠体31の取付けの際の縦横枠部材31a〜31dの寸法調整等を行う際に支障を来さないようにしているので、張設したネット32にある程度強い風などの外力が作用したときには、図4に示すように、ネット32が風下側に膨らんで、その上下端が横枠部材31c,31dから脱出し、その部分において防虫の目的を達成できなくなるばかりでなく、その都度ネットの上下端を横枠部材31c,31d内に復帰させる作業が必要となる。
【0005】
即ち、上記ネット32は、重り36によりワイヤに作用する張力でその姿勢を所定の張設状態に保持し、比較的弱い風では風下側になびかないようにしているが、それにある程度強い外力が作用したときには、重り36を図4に示すような当接部38への当接位置まで引き上げながら風下側に膨らむので、それに伴って伸縮自在のネット32の上下端が横枠部材31c,31dから外れ、上記不都合が生じることになる。
【0006】
また、この不都合を避けるために重り36をより重くすると、風等によるネットの膨らみを一層抑制できるが、ネット32の張設操作のための操作框33の操作力が大きくなり、しかも、張設したネット32を該重り36の作用で自動開放するとき、操作框33が開放側の縦枠部材に強く衝突し、大きな衝撃音を発すると共に、衝撃によって一部が破損する可能性も生じることになる。
【0007】
【課題を解決するための手段】
上記課題を解決するための本発明の横引き式網戸は、多数の平行で等間隔な折曲部において交互に逆方向に折曲することによりアコーディオン式に伸縮自在としたネットを、枠体内において横引き式に開閉自在とし、上記ネットの一端を上記枠体の縦枠部材に固定すると共に、該ネットの他端を上記枠体に沿って摺動する開閉操作用の操作框に取り付けた横引き式網戸において、一端を上記操作框に固定したワイヤを上記ネット中に水平に挿通したうえで、上記縦枠部材に設けたガイド部材を介して該縦枠部材中に垂下させ、該縦枠部材中においてそのワイヤの先端に重りを吊下し、あるいは、一端を上記縦枠部材に固定したワイヤを、上記ネット中に水平に挿通したうえで、上記操作框に設けたガイド部材を介して該操作框中に垂下させ、該操作框中においてそのワイヤの先端に重りを吊下し、上記ネットが張設状態にあるときの上記重りとその上昇限となる当接部とに接するようにそれらの間にばね部材を介装したことを特徴とするものである。
【0008】
【課題を解決するための手段】
上記課題を解決するための本発明の横引き式網戸は、多数の平行で等間隔な折曲部において交互に逆方向に折曲することによりアコーディオン式に伸縮自在としたネットを、枠体内において横引き式に開閉自在とし、上記ネットの一端を上記枠体の縦枠部材に固定すると共に、該ネットの他端を上記枠体に沿って摺動する開閉操作用の操作框に取り付けた横引き式網戸において、一端を上記操作框に固定したワイヤを上記ネット中に水平に挿通したうえで、上記縦枠部材に設けたガイド部材を介して該縦枠部材中に垂下させ、該縦枠部材中においてそのワイヤの先端に重りを吊下し、あるいは、一端を上記縦枠部材に固定したワイヤを、上記ネット中に水平に挿通したうえで、上記操作框に設けたガイド部材を介して該操作框中に垂下させ、該操作框中においてそのワイヤの先端に重りを吊下し、上記ネットが張設状態にあるときの上記重りとその上昇限となる当接部との間にばね部材を介装したことを特徴とするものである。
【0009】
上記横引き式網戸においては、一端を操作框または縦枠部材に固定したワイヤの複数をネットに多段に挿通し、それらのワイヤの他端を縦枠部材または操作框に設けたガイド部材を介して、該縦枠部材または操作框中にその上部から一纏めにして垂下させ、これによって操作框を平行移動させることができる。
また、上記重りとその上昇限となる当接部との間のばね部材を、ネットが張設状態にあるときに若干圧縮された状態として介装することができる。
【0010】
上記構成を有する横引き式網戸は、建物開口部に設置し、そこにネットが張設された状態において、該ネットにある程度強い風などの外力が作用して、ワイヤに重りを持ち上げる方向の力が作用しても、該重りが持ち上げられるときに、該重りと当接部との間に介装したばね部材の力がワイヤに作用するので、上記外力によってワイヤに撓みが生じるのを抑制することができ、その結果、ネットの膨れを抑制することができる。
【0011】
一方、張設状態にあるネットを開放する場合には、操作框の拘束を解除することにより、ワイヤを介して操作框に作用する重りの作用力で自動的にネットが折り畳まれ、開放される。この場合、上記ばね部材の力は、初期段階を除いて操作框の開放動作には関与しないので、操作框に作用する重りの力にばね部材の力が常に加重されたりすることはなく、該ばね部材の存在により操作框がネットの開放時に側枠に強く衝突するようなことはない。
また、上記重りと当接部との間のばね部材を、ネットが張設状態にあるときに若干圧縮された状態として介装すると、ネットの張設時におけるワイヤの張力を高めると同時に、操作框を操作してネットを張設操作する終端での縦枠部材に対する操作框の衝突力が該ばね部材により緩和される。
【0012】
【発明の実施の形態】
図1は本発明に係る横引き式網戸の第1実施例を示している。
この第1実施例の横引き式網戸は、多数の平行で等間隔な折曲部12aにおいて交互に逆方向に折曲することによりアコーディオン式に伸縮自在とした防虫用のネット12を、建物開口部に固定される枠体11内において横引き式に開閉自在としたものである。上記枠体11は、アルミニウムあるいは合成樹脂からなる一対の縦枠部材11a,11b、及び上下の横枠部材11c,11dを四隅において相互に連結することにより構成されたものである。
【0013】
上記ネット12は、その一端を上記枠体11の一方の縦枠部材11aに固定すると共に、該ネット12の他端を上記枠体11の上下の横枠部材11c,11dに沿って摺動する開閉操作用の操作框13に取り付けている。該操作框13は、その上端部に取り付けられた転輪13aを上部の横枠部材11c内に設けたレール上において走行させるようにしている。また、該ネット12の上下端は上記横枠部材11c,11dに設けた溝によってガイドさせている。
【0014】
上記横引き式網戸においては、ネット12中の上下部及びそれらの中間部の各水平方向に略等間隔でワイヤ14a〜14dを多段に挿通し、該ワイヤ14a〜14dの各一端を上記操作框13に固定すると共に、それらのワイヤ14a〜14dの他端を、ネット12中に挿通したうえで縦枠部材11a内に挿通し、最上位のワイヤ14aを除く他のワイヤ14b〜14dを、図示を省略している転向子を介して縦枠部材11a内を上方に導き、それらを最上位のワイヤ14aと共に縦枠部材11aの上部に設けたガイド部材15を介して、縦枠部材11a中に垂下させ、該縦枠部材11a中において、それらのワイヤ14a〜14dの先端に重り16を吊下している。
【0015】
縦枠部材11a中に垂下させる上記ワイヤ14a〜14dは、それらを個別的に垂下させて先端に重り16を取り付けることもできるが、それらを一纏めにして垂下させることもできる。このように、ワイヤ14a〜14dの複数をネット12に多段に挿通し、縦枠部材内においてそれらのワイヤに重り16を吊下すると、各ワイヤに略均等に作用する張力によって操作框13を平行移動させることができる。また、風圧等の作用によりネット12が風下側に膨らんだりするのが抑制される。
なお、縦枠部材11bと操作框13との間には、上記重り16によるワイヤの張力に抗して操作框13をネットの張設位置に保持する掛け金具17を設けている。
【0016】
また、上記網戸においては、ネット12が図1に示すような張設状態にあるときに、上記重り16とその上昇限となる当接部18とに接するようにそれらの間にばね部材19を介装している。上記重りと当接部との間に介装するばね部材19は、ネット12が張設状態にあるときにそれに圧縮力が作用しない状態で介装することもできるが、若干圧縮された状態として介装することもできる。また、上記ばね部材19としては、ワイヤの周囲に外嵌するコイルばねを用いるのが望ましいが、スポンジ状その他の弾性体を用いることもできる。
【0017】
上記構成を有する横引き式網戸は、建物開口部に設置し、そこにネット12が張設された状態において、該ネット12にある程度強い風などの外力が作用し、ワイヤ14a〜14dに重り16を持ち上げる方向の力が作用しても、該重りが持ち上げられるときに、該重り16と当接部18との間に介装したばね部材19の力がワイヤ14a〜14dに作用するので、上記外力によってワイヤに撓みが生じるのを抑制することができ、その結果、ネットの膨れを抑制することができる。
【0018】
一方、張設状態にあるネット12を開放する場合には、掛け金具17による操作框13の拘束を解除することにより、ワイヤ14a〜14dを介して操作框13に作用する重り16の作用力で自動的にネット12が折り畳まれ、建物開口部が自動開放される。
【0019】
この場合に、上記ばね部材19を、ネット12が張設状態にあるときにそれに圧縮力が作用しない状態で介装していれば、該ばね部材の力が操作框13の開放動作には関与しないので、操作框13はそれに作用する重り16の力により開放動作し、操作框13の動作にばね部材19の力が影響するようなことはない。
また、ばね部材19を、ネット12が張設状態にあるときに若干圧縮された状態として介装すると、上記ばね部材19の力が、ネット開放の初期段階において操作框13の開放動作に若干関与するが、常に操作框13に作用する重り16の力にばね部材19の力が加重されたりすることはなく、ネット12の張設時におけるワイヤ14a〜14dの張力を若干でも高めると同時に、操作框13を操作してネット11を張設操作する終端での縦枠部材11bに対する操作框13の衝突力が該ばね部材19により緩和される。
【0020】
図2は、本発明に係る横引き式網戸の第2実施例を示すもので、縦枠部材21a,21b、及び上下の横枠部材21c,21dからなる枠体21内において、ネット22を横引き式に開閉自在としているが、上記第1実施例と比べて、複数のワイヤ24a〜24dの一端を縦枠部材21aに取り付け、該ワイヤ24a〜24dをネット22中に水平に挿通したうえで、操作框23に設けたガイド部材25を介して該操作框23中に垂下させ、該操作框23中においてそのワイヤの先端に重り26を吊下した点で相違している。
【0021】
また、第1実施例との上記構成の相違に伴い、ネット22中に多段に挿通した各ワイヤ24a〜24dを操作框23内に挿通し、最上位のワイヤ24aを除く他のワイヤ24b〜24dを、図示を省略している転向子を介して操作框23内を上方に導き、それらを最上位のワイヤ24aと共に操作框23の上部に設けたガイド部材25を介して操作框23中に垂下させ、該操作框23中において、それらのワイヤ24a〜24dの先端に重り26を吊下し、ネット22が張設状態にあるときの上記重り26とその上昇限となる当接部28との間にばね部材29を介装している。
【0022】
この第2実施例の横引き式網戸においては、上述したように、重り26により操作框23には開方向の作用力が付与される同時に、ワイヤ24a〜24dに張力が付与され、該張力によりネット22の姿勢が安定化され、風圧等の作用による該ネット22の膨らみ等が防止される点では、前記第1実施例と変わるところがないが、掛け金具27による操作框23の拘束を解除し、ワイヤ24a〜24dに作用する張力によって操作框23を開方向に移動させて、ネット22を自動開放する場合には、重り26の作用力(位置エネルギ)が、操作框23を開方向に駆動するのに消費されるのは勿論であるが、操作框23と共に重り26自身を移動させるためにも消費され、そのため、第1実施例の場合に比して、操作框23の加速に供される力が軽減され、操作框23が開放端において縦枠部材11aに強く衝突するようなことが回避される。
【0023】
なお、第2実施例の上記以外の構成及び作用効果は、第1実施例の場合と変わるところがないので、それらの説明は省略する。
また、以上において、本発明に係る横引き式網戸の実施の形態について詳述したが、本発明はその特許請求の範囲に記載されている発明の精神を逸脱しない範囲で、設計において種々の変更ができるものである。
【0024】
【発明の効果】
以上に詳述した本発明の横引き式網戸によれば、上述したばね部材の設置により、ワイヤに吊下する重りを必要以上に大きくすることなしに、ネットが張設状態にあるときだけワイヤに作用する張力を高め、それによって、張設したネットにある程度強い風などの外力が作用したときのネットの膨らみを抑制でき、結果的に、ネット上下端の横枠部材からの脱出を可及的に抑制することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a screen door that is attached to an opening of a building to prevent insects, and an accordion-type telescopic net can be opened and closed by lateral pulling.
[0002]
[Prior art]
Conventionally, a screen 32 as shown in FIG. 3, that is, a net 32 that can be expanded and contracted in an accordion manner by alternately bending in opposite directions at a large number of parallel and equally spaced folding portions, A horizontal screen door that can be opened and closed in a horizontal manner is very generally known. In this horizontal sliding screen door, one end of the net 32 is fixed to one vertical frame member 31 a of the frame 31, and the other end of the net 32 is fixed to the upper and lower horizontal frame members 31 c and 31 d of the frame 31. Is attached to an operating rod 33 for opening and closing that slides along the upper and lower ends of the net 32, and the upper and lower ends of the net 32 are guided in a state of being fitted into the horizontal frame members 31c and 31d, thereby making the net 32 openable and closable.
[0003]
As illustrated in FIG. 3, in the horizontal sliding screen door, the wires 34 a to 34 d having one end fixed to the operation rod 33 are horizontally inserted into the net 32 and then provided to the vertical frame member 31 a. When the net 32 is in the stretched state, it is suspended in the vertical frame member via the guide member 35 and the weight 36 is suspended from the ends of the wires in the vertical frame member 31a. When the hanging bracket 37 provided between the vertical frame member 31b with which the contact 33 abuts and the operation rod 33 is removed, the net 32 in the stretched state is automatically folded by the action of the weight 36, and the building The opening can be opened automatically.
[0004]
However, the wire length is usually set so that a certain distance d is formed between the weight 36 when the net 32 is in the stretched state and the abutting portion 38 that is the upper limit of the weight 36, and the opening to the building opening. When adjusting the dimensions of the vertical and horizontal frame members 31a to 31d when the frame body 31 is attached, the external force such as a strong wind is applied to the stretched net 32. As shown in FIG. 4, the net 32 swells to the leeward side, and the upper and lower ends thereof escape from the horizontal frame members 31c and 31d. The operation | work which resets an edge in the horizontal frame members 31c and 31d is needed.
[0005]
That is, the net 32 keeps its posture in a predetermined tension state by the tension acting on the wire by the weight 36 so that it does not flutter on the leeward side with a relatively weak wind. In this case, the weight 36 swells to the leeward side while being pulled up to the contact position with the contact portion 38 as shown in FIG. 4, and accordingly, the upper and lower ends of the extendable net 32 are disengaged from the horizontal frame members 31c and 31d. The above inconvenience occurs.
[0006]
Further, if the weight 36 is made heavier to avoid this inconvenience, the bulging of the net due to wind or the like can be further suppressed, but the operating force of the operating rod 33 for the operation of extending the net 32 is increased, and moreover, When the opened net 32 is automatically opened by the action of the weight 36, the operating rod 33 strongly collides with the vertical frame member on the open side, and a large impact sound is generated. Become.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the horizontal sliding screen door of the present invention has an accordion-type net that can be expanded and contracted alternately in a large number of parallel and equally-folded folding portions in a frame. A horizontal pulling type that is openable and closable, with one end of the net fixed to the vertical frame member of the frame, and the other end of the net attached to an operating rod for sliding operation that slides along the frame. In the sliding screen door, a wire having one end fixed to the operation rod is horizontally inserted into the net, and then suspended in the vertical frame member through a guide member provided on the vertical frame member. A weight is suspended from the tip of the wire in the member, or a wire having one end fixed to the vertical frame member is inserted horizontally into the net, and then inserted through the guide member provided on the operation rod. Hang down in the operation cage, During operation stile suspended from a weight to the tip of the wire, interposed a spring member therebetween so as to be in contact with the above weight and the abutment thereof the ascent limit when the net is in a tensioned state It is characterized by that.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the horizontal sliding screen door of the present invention has an accordion-type net that can be expanded and contracted alternately in a large number of parallel and equally-folded folding portions in a frame. A horizontal pulling type that is openable and closable, with one end of the net fixed to the vertical frame member of the frame, and the other end of the net attached to an operating rod for sliding operation that slides along the frame. In the sliding screen door, a wire having one end fixed to the operation rod is horizontally inserted into the net, and then suspended in the vertical frame member through a guide member provided on the vertical frame member. A weight is suspended from the tip of the wire in the member, or a wire having one end fixed to the vertical frame member is inserted horizontally into the net, and then inserted through the guide member provided on the operation rod. Hang down in the operation cage, A weight is suspended from the tip of the wire in the operation rod, and a spring member is interposed between the weight when the net is in a tensioned state and the abutting portion which is the ascending limit. To do.
[0009]
In the above-described horizontal screen door, a plurality of wires fixed at one end to the operation rod or the vertical frame member are inserted into the net in multiple stages, and the other ends of these wires are passed through a guide member provided on the vertical frame member or the operation rod. Thus, the vertical frame member or the operating rod can be suspended together from the upper portion thereof, whereby the operating rod can be translated.
Further, the spring member between the weight and the abutting portion which is the upper limit thereof can be interposed in a slightly compressed state when the net is in the tensioned state.
[0010]
The horizontal screen door having the above configuration is installed in the opening of a building, and when the net is stretched there, external force such as strong wind acts on the net to force the wire to lift the weight. Even when the weight is lifted, the force of the spring member interposed between the weight and the abutting portion acts on the wire when the weight is lifted, so that the bending of the wire due to the external force is suppressed. As a result, the swelling of the net can be suppressed.
[0011]
On the other hand, when opening the net in the stretched state, the net is automatically folded and released by the weight acting on the operating rod via the wire by releasing the restraint of the operating rod. . In this case, since the force of the spring member is not involved in the opening operation of the operating rod except in the initial stage, the force of the spring member is not always applied to the force of the weight acting on the operating rod. Due to the presence of the spring member, the operating rod does not strongly collide with the side frame when the net is opened.
In addition, if the spring member between the weight and the abutting portion is interposed in a slightly compressed state when the net is in the tensioned state, the wire tension during the tensioning of the net is increased, and at the same time The impact force of the operating rod against the vertical frame member at the terminal end where the net is extended by operating the rod is reduced by the spring member.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a first embodiment of a horizontal screen door according to the present invention.
In the first embodiment, the horizontal screen door is constructed of an insect repellant net 12 which can be expanded and contracted in an accordion manner by alternately bending in opposite directions at a number of parallel and equally spaced bent portions 12a. It can be opened and closed in a horizontal manner in a frame 11 fixed to the part. The frame 11 is configured by connecting a pair of vertical frame members 11a and 11b made of aluminum or synthetic resin and upper and lower horizontal frame members 11c and 11d to each other at four corners.
[0013]
One end of the net 12 is fixed to one vertical frame member 11 a of the frame body 11, and the other end of the net 12 is slid along the upper and lower horizontal frame members 11 c and 11 d of the frame body 11. It is attached to an operating rod 13 for opening / closing operation. The operating rod 13 is configured such that a wheel 13a attached to the upper end of the operating rod 13 travels on a rail provided in the upper horizontal frame member 11c. The upper and lower ends of the net 12 are guided by grooves provided in the horizontal frame members 11c and 11d.
[0014]
In the horizontal type screen door, the wires 14a to 14d are inserted into the upper and lower portions of the net 12 and the intermediate portions thereof in the horizontal direction at approximately equal intervals in multiple stages, and one end of each of the wires 14a to 14d is inserted into the operation rod. 13, the other ends of the wires 14 a to 14 d are inserted into the net 12 after being inserted into the net 12, and the other wires 14 b to 14 d except for the uppermost wire 14 a are illustrated. The vertical frame member 11a is guided upward through a turning element that is omitted, and the uppermost wire 14a and the guide member 15 provided on the upper part of the vertical frame member 11a are inserted into the vertical frame member 11a. A weight 16 is suspended from the tips of the wires 14a to 14d in the vertical frame member 11a.
[0015]
The wires 14a to 14d suspended in the vertical frame member 11a can be individually suspended to attach the weight 16 to the tip, but they can also be suspended together. As described above, when a plurality of the wires 14a to 14d are inserted into the net 12 in multiple stages and the weights 16 are suspended from the wires in the vertical frame member, the operation rod 13 is paralleled by tension acting substantially equally on each wire. Can be moved. Further, the net 12 is prevented from bulging to the leeward side due to the action of wind pressure or the like.
Note that a hook 17 is provided between the vertical frame member 11b and the operating rod 13 to hold the operating rod 13 at the net extension position against the tension of the wire due to the weight 16.
[0016]
Further, in the screen door, when the net 12 is in a stretched state as shown in FIG. 1, a spring member 19 is interposed between the weight 16 and the contact portion 18 which is the upper limit thereof. It is intervening. The spring member 19 interposed between the weight and the contact portion can be interposed in a state where the compression force does not act on the net 12 when the net 12 is in the tensioned state. It can also be inserted. The spring member 19 is preferably a coil spring that is fitted around the wire, but a sponge-like or other elastic body can also be used.
[0017]
The horizontal type screen door having the above-described configuration is installed in a building opening, and in a state where the net 12 is stretched there, an external force such as a strong wind acts on the net 12, and the weights 16 are applied to the wires 14a to 14d. Even when a force in the direction of lifting is applied, the force of the spring member 19 interposed between the weight 16 and the contact portion 18 acts on the wires 14a to 14d when the weight is lifted. It is possible to suppress the bending of the wire due to the external force, and as a result, it is possible to suppress the swelling of the net.
[0018]
On the other hand, when the net 12 in the stretched state is opened, the operating force of the weight 16 acting on the operating rod 13 via the wires 14a to 14d is released by releasing the restraint of the operating rod 13 by the hook 17. The net 12 is automatically folded and the building opening is automatically opened.
[0019]
In this case, if the spring member 19 is interposed in a state where the compression force is not applied to the net 12 when the net 12 is stretched, the force of the spring member is involved in the opening operation of the operating rod 13. Therefore, the operating rod 13 is opened by the force of the weight 16 acting on the operating rod 13, and the force of the spring member 19 does not affect the operation of the operating rod 13.
Further, when the spring member 19 is interposed in a slightly compressed state when the net 12 is in the tensioned state, the force of the spring member 19 is slightly involved in the opening operation of the operating rod 13 in the initial stage of the net opening. However, the force of the spring member 19 is not always applied to the force of the weight 16 acting on the operation rod 13, and the tension of the wires 14a to 14d when the net 12 is stretched is slightly increased and the operation is performed at the same time. The impact force of the operating rod 13 against the vertical frame member 11b at the end of operating the rod 13 to stretch the net 11 is alleviated by the spring member 19.
[0020]
FIG. 2 shows a second embodiment of the horizontal type screen door according to the present invention. In the frame body 21 composed of the vertical frame members 21a and 21b and the upper and lower horizontal frame members 21c and 21d, the net 22 is arranged horizontally. Although it can be opened and closed in a pulling manner, one end of the plurality of wires 24 a to 24 d is attached to the vertical frame member 21 a and the wires 24 a to 24 d are horizontally inserted into the net 22 as compared with the first embodiment. The difference is that the operation rod 23 is suspended through a guide member 25 provided on the operation rod 23, and a weight 26 is suspended from the end of the wire in the operation rod 23.
[0021]
Further, due to the difference in configuration from the first embodiment, the wires 24a to 24d that are inserted into the net 22 in multiple stages are inserted into the operation rod 23, and the other wires 24b to 24d other than the uppermost wire 24a are inserted. Are guided upward in the operation rod 23 through a turning element (not shown) and suspended in the operation rod 23 through a guide member 25 provided on the upper portion of the operation rod 23 together with the uppermost wire 24a. are allowed, during the operation rail 23, suspended from a weight 26 on the tip of their wires 24 a to 24 d, and the weight 26 and the abutment 28 that the ascent limit when the net 22 is in the tensioned state A spring member 29 is interposed therebetween.
[0022]
In the horizontal type screen door according to the second embodiment, as described above, the operating force 23 is applied to the operating rod 23 by the weight 26, and at the same time, tension is applied to the wires 24a to 24d. There is no difference from the first embodiment in that the posture of the net 22 is stabilized and the bulging of the net 22 due to the action of wind pressure or the like is prevented, but the restraint of the operating rod 23 by the hook 27 is released. When the operating rod 23 is moved in the opening direction by the tension acting on the wires 24a to 24d and the net 22 is automatically opened, the acting force (potential energy) of the weight 26 drives the operating rod 23 in the opening direction. Of course, it is consumed for moving the weight 26 together with the operating rod 23, and therefore, it is used for acceleration of the operating rod 23 as compared with the case of the first embodiment. Power Is reduced, the operation rail 23 is avoided so as to collide strongly vertical frame member 11a at the open end.
[0023]
In addition, since the structure and effect other than the above of 2nd Example do not change with the case of 1st Example, those description is abbreviate | omitted.
In the above, the embodiment of the horizontal screen door according to the present invention has been described in detail. However, the present invention is not limited to the scope of the invention described in the claims, and various changes in design can be made. It is something that can be done.
[0024]
【The invention's effect】
According to the horizontal type screen door of the present invention described in detail above, the wire is provided only when the net is in the tensioned state without increasing the weight suspended from the wire more than necessary by installing the spring member described above. The tension that acts on the net can be increased, thereby suppressing the expansion of the net when external force such as strong wind acts on the stretched net, and as a result, it is possible to escape from the horizontal frame members at the upper and lower ends of the net. Can be suppressed.
