Abstract

<P>PROBLEM TO BE SOLVED: To provide a sash roller for a wire screen, which almost completely eliminates a fear of the slipout of the wire screen from a window frame due to an impact at the time of opening/closing the same, contributes to the easy and quick attachment/detachment of the wire screen to/from the window frame, and has a function of behaving so as to automatically eliminate a gap between the window frame and the wire screen, even if the fitting accuracy of the wire screen is poor, and to provide the wire screen which has the sash rollers attached thereto. <P>SOLUTION: The wire screen is formed of a base block, a wheel bearing arm formed of a leaf spring, an arm fixing means, and a fixture canceling means. The base block is screw-fitted to a frame of the wire screen. The wheel bearing arm has its base-side end fixed to the base block, and pressingly energizes a wheel attached to the tip thereof to a traveling rail. The arm fixing means temporarily fixes the arm at a location at which the wheel is most separate from the traveling rail. The fixture canceling means cancels temporary fixture. The wire screen has the sash rollers mounted thereon at four upper and lower corners thereof. Here, the sash rollers on the upper side of the wire screen can dispense with the arm fixing means. <P>COPYRIGHT: (C)2004,JPO

【発明の属する技術分野】
本発明は、網戸が開閉時のはずみで窓枠から外れてしまったり、網戸をムーズに動かせなかったり、或いは、外れ防止対策を講ずると、網戸を外したい時に簡単に外れなくなる、といった従来の問題点を概ね解消させ得る様に改良された網戸用の戸車、及びこの戸車を取付けた網戸に関する。
【0002】
【従来の技術】
図12は、従来の一般的な構造の戸車70を、網戸100に取付けた状態を示した部分図で、(a)は透視正面図、(b)はその下面視図である。
戸車70は、車輪71を組付けた本体ブロック72を、止螺73によって網戸の縦枠100aに固定させている。74は、車輪71の位置を上下に微調整する為の位置調節螺である。
車輪71の軸受部材75は、この調節を終えた位置に固定される。100bは網戸の横枠、100cは防虫ネット、200は車輪71を載せる走行レールである。
【0003】
上記の様に、車輪71の軸受部材75を、その枠組に固定状態で取付けた従来の網戸100は、開け閉めの際のはずみで、車輪71が走行レール200から外れ易い傾向があった。又、網戸100をスムーズに開閉させ難いきらいもあった。
殊に、横幅寸法に比べて、背丈が高過ぎる網戸は然りである。
そして、建物が古くなって、立て付けが悪い等の状況にあれば尚更である。
【0004】
この様に、車輪71が走行レール200から外れ易かったり、網戸100をスムーズに動かせないのは、網戸100の枠組が軽く、華奢に作られている為に、開閉時に、網戸100が上下に揺動したり、枠組が歪み勝ちな為である。
或いは、網戸100の枠組が経年変形していたり、窓枠が正確に作られていなかったり、年月を経て変形していることも、上記の不調の原因になる。
【0005】
窓枠から外れ易い網戸は、外れた都度、嵌め直さねばならず甚だ手間が掛かる。
高齢者所帯であれば、尚更この問題の改善が望まれる。
そればかりではなく、二階建以上の高い建物の部屋から、網戸が外れて落下すれば、その直下の地上にたまたま人が居れば、重大な事態を招き兼ねない。
そこで、戸車の車輪を、バネ力によって常時レールに押し付けて置く様に構成した戸車も考案されている。
或いは、網戸の上側の枠に、外れ防止用の部材を取付けたものもある。
【0006】
【発明が解決しようとする課題】
然しながら、上記の様に、一旦窓枠に嵌め込んだ網戸が、不用意に外れてしまうのを防ぐ為に、極力しっかり取付け様とすればする程、網戸を取り外す時に、取り外し作業に手こずる結果を招いていた。
又、網戸の外れ防止策を講じた従来の戸車には、製作コスト、耐久性、取付けの際の手間等の点で改善の余地が多分に残されている。
【0007】
そこで、本発明の目的は、網戸が、開閉時のはずみで窓枠から脱落してしまう恐れをほぼ確実に無くし、然も、網戸の取り外しも、簡単・迅速に行え、更には、網戸の立て付けが悪い状態でも、窓枠と網戸との間の隙間を自ずから無くす様に挙動する機能も備えた網戸用の戸車、及びこの戸車を取付けた網戸を提供するにある。
【0008】
【課題を解決するための手段】
上記の目的を達成する為の、本発明による網戸用の戸車は、
開閉時のはずみで、網戸の車輪が走行レールから外れてしまったり、網戸がスムーズに動かない等の、従来の戸車や網戸の不具合を解消させ得る様に構成したものであって、
網戸の枠組に螺止させるベースブロックと、
その基端側をベースブロックに固定させ、先端側に車輪の軸受部が設けられて、車輪を走行レールに向けて押圧付勢する板バネ製の車輪支持アームと、
車輪支持アームを、車輪が走行レールから最も隔てられた位置に迄屈曲させた状態に仮固定する為のアーム固定手段と、
前記固定状態を解除させる固定解除手段とを備えることを特徴とする。
そして、アーム固定手段は、
ベースブロックに軸支され、その先端にフックを設けた揺動爪と、
揺動爪の先端を、常時は、車輪支持アームに摺接状態に保たせるべく、揺動爪を回動付勢するバネと、
車輪支持アームが前記屈曲状態に迄達した時に、フックを掛合させてこの屈曲状態を固定する為に、車輪支持アームの所定箇所に設けた掛止孔とを備えることを特徴とする。
又、固定解除手段は、掛止孔に掛合されたフックを掛止孔から押し出す為に、その軸方向に前後動可能にベースブロックに組付けたレバー状ロッドを備えることを特徴とする。
レバー状ロッドには、その先端に折曲部を、基端にその回動用の摘みを設けてあり、
折曲部を横向位置にもたらすと、揺動爪が車輪支持アームから遠ざかった回動位置に固定され、縦向位置にもたらすと、この固定状態が解除され、又、レバー状ロッドを前進動させてフックを押しやることにより、車輪支持アームの固定状態を解除させる様に構成したことを特徴とする。
更に、板バネ製の車輪支持アームには、バネ力調節機構が付設されており、
このバネ力調節機構は、並列状に対置したベースブロックの下面と車輪支持アームとの間に左右動自在に組込まれた摺動子と、摺動子に設けた螺孔にその先端部を螺合させ、基端側はベースブロックに挿通状態で掛止させた押・引螺と、ベースブロックと摺動子と間に介在させたコイルバネとを備えることを特徴とする。
【0009】
本発明による網戸は、
本発明による上記の構成を備えた戸車を、網戸の上下の四隅箇所の夫々に取付けたことを特徴とする。
但し、上側の戸車は、アーム固定手段を省くことが出来る。
【0010】
【発明の実施の形態】
以下に、本発明の一実施例に就いて、図1〜図11を参照しながら説明する。図1は、本発明による戸車Aを取付けた網戸100の要部を示した、部分正面視図である。
図中の100a及び100bは、網戸100の枠組を構成する左右の縦枠及びは上下の横枠であり、100cは、この枠組に張設した防虫用ネットである。
【0011】
従って、網戸100は、その下上両端の、各左右両側の、計4箇所に戸車Aを取付けていることになる。
但し、図1に示した上側の2箇の戸車A2は、後述する様に、一旦、窓枠に嵌め込んだ網戸100を、シーズンオフになって窓枠から取り外す作業を容易にする為の機構が省かれている点で、下側の2箇の戸車A1とは相異している。
この相異点を除けば、戸車A1とA2との基本的な構造は、共通している。
【0012】
そこで、以下は、下側の戸車A1に就いて、その具体的な構造を順次説明する。
図2及び図3は、戸車A1の正面図及び透視正面図、図4は、戸車A1の本体部分だけを示した正面図及びその上下左右の4方向視図である。
図5は、戸車A1の主要部分の分解斜視図であり、図6は、それ等の組立状態を示す斜視図である。
【0013】
図7は、後述する、板バネ製の車輪支持アーム20のバネ力を調節する為の、バネ力調節機構の分解正面図及び摺動子の透視斜視図であり、図8は、車輪21の正面図及び側面図である。
図9は、車輪支持アーム20の上下動を規制する、アーム固定・固定解除手段の構成を示す斜視図、図10は、この手段の本体を成す揺動爪及びその回動付勢バネの各正面図である。
そして、図11は、戸車A1の作動説明図である。
【0014】
戸車A1の概略の構成は、図2,図3に示した様に、網戸100の縦枠100aに螺止されるベースブロック10と、その基端側をベースブロック10に固定され、先端側に車輪21を組付けた、板バネ製の車輪支持アーム20と、車輪21を、その走行レール200から最も隔たった位置に固定させる為のアーム固定手段30、及び固定解除手段40とを備えている。
【0015】
先ず、ベースブロック10は、図1〜図6に示した様に、止螺11によって縦枠100aに固定される縦向ブロック12に、縦枠100bの下面に当接させる横向ブロック13を、ほぼL形に連結させた形態を備えている。
横向ブロック13の先端側には、軸孔を穿った2枚の軸受板14,14を対向状に垂設している。
尚、図4〜図6では、構造を理解し易い様に、手前側の軸受板14を跳ね上げた状態で示している。
【0016】
次に、車輪支持アーム20は、帯板状のバネ材製で、その水平部20aの基端側(図では右端側)を上向きに折曲して設けた立上部20bに、止螺11等を通すボトル孔を上下2箇所に設けている。
水平部20aの先端側には、車輪21の車軸を通す軸孔を設けた2枚の軸受板20cを、対向状に垂設している。
【0017】
従って、車輪21を走行レール200に載せた状態で、両手で支持した網戸100を上下動させても、所定の上下動高さの範囲内では、車輪21は、車輪支持アーム20のバネ作用力によって、常に、走行レール200上に圧接状態に保たれ続ける。それに伴って、車輪支持アーム20は、図11に示した様に、上下に屈曲動させられることになる。
【0018】
更に、車輪支持アーム20の水平部20aには、図5、等に示した様に、その先端近い箇所に、後述する揺動爪32のフック32aを掛止させる為の掛止孔22を、上向きに設けている。
【0019】
バネ材製の車輪支持アーム20には、そのバネ作用力を調節する為のバネ力調節機構50も組付けている。
このバネ力調節機構50は、図3,図7、等に示した様に、ベースブロック10の横向ブロック13の下面側に沿って左右に摺動自在の摺動子51と、その左右動用の押・引螺52と、押・引螺52に外嵌させたコイルバネ53とから成る。
【0020】
図3に示した様に、車輪支持アーム20の水平部20aは、横向ブロック13の下面と対向する様に並列状に配設されており、摺動子51は、横向ブロック13の下面と水平部20aとの間で挟み付けられた状態にある。
その為、上下に屈曲自在の車輪支持アーム20は、摺動子51の下面前縁部との接触箇所が、その屈曲動時の支点となる(図11参照)。
【0021】
押・引螺52は、縦向ブロック12に設けた挿通孔にその外側から挿通させたうえ、その先端部を摺動子51に設けた螺孔51aに螺合させている。
そして、コイルバネ53は、縦向ブロック12と摺動子51と間に挟み込ませた状態で、押・引螺52に外嵌させている。
車輪支持アーム20は、図1に示した様に、網戸100を窓枠に嵌め込んだ状態で、そのバネ力により車輪21が、常時、走行レール200に圧接される様に配設している。
【0022】
従って、押・引螺52を正・逆回転させて、摺動子51の位置を左右に変位させれば、車輪支持アーム20の支点が変動することになり、その分、バネ作用力を調節することが出来る。
尚、車輪支持アーム20に設けた軸受板20cは、アームの屈曲動を妨げるので、軸受板20cは、摺動子51に近づき過ぎない様にその位置と形状を決める必要がある。
【0023】
次に、アーム固定手段30は、図5,図6、及び図9〜図11、等に示した様に、ベースブロック10の軸受板14,14に組付けた支軸31に、その基端側を軸支されて上下に揺動自在の揺動爪32と、揺動爪32の先端に下向きに設けたフック32aを係脱自在に掛止させる為に、車輪支持アーム20の先端側に設けた掛止孔22とを組合わせた構成を備えている。
支軸31には、揺動爪32を下向きに回動付勢するコイルバネ33を組付けている。
【0024】
車輪支持アーム20の固定解除手段40は、図3、図9、等に示した様に、ベースブロック10の縦向ブロック12と、アーム固定手段30としての揺動爪32との間に跨設されて、その軸周りに回動自在で、且つ、軸方向に前後動可能なレバー状ロッド41を、その本体としている。
【0025】
レバー状ロッド41の先端側は、図9に示した様に揺動爪32に設けた掛止溝に載せ架けた状態で、その突出端部を直角に折り曲げて、折曲部41aを設けている。
そして、レバー状ロッド41の基端側は、図3に示した様に、縦向ブロック12に設けた挿通孔を通してその外側に突出させ、この突出端に摘み42を取付けている。
【0026】
次に、網戸100の上端に取付ける戸車A2の構造に就いては、既述の様に、アーム固定手段30及び固定解除手段40を省いた点を除いて、下側の戸車A1と同じなので説明は省くことにする。
尚、上側の戸車A2は、下側の戸車A1に比べて負荷が少ないので、その分、車輪21の径をより小さくしている。
【0027】
次に、戸車A1の作動に就いて説明する。
この実施例では、既述の様に、網戸100の上下の四隅箇所の夫々に、戸車A1又はA2を取付けている。
然し、背丈が低い網戸であれば、縦長の網戸に比べてスムーズに開閉出来るので、本発明による戸車Aは、必ずしも必要としない。
網戸100への戸車Aの取付方は、既述の如くである。
【0028】
先ず、網戸100を窓枠(図示略)に嵌め込むのに先だって、戸車A1のレバー状ロッド41の摘み42を回動操作して、折曲部41aを、図9の(b)に示した様に、下向きの回動位置にもたらして置く。
この状態では、コイルバネ33により下向きに回動付勢されている揺動爪32が、折曲部41aによって、その回動を妨害されることはない。
【0029】
網戸100を窓枠に嵌め込む為に、網戸100を持ち上げた状態では、車輪21には何等の押圧力も及ぼされていないので、無負荷状態の車輪支持アーム20は、図2に示した様に水平向きに真っ直ぐに伸びている。
この時、車輪21は、下向きに最も突出した状態にある(図11参照)。
【0030】
一方、網戸100の上端に取付けた戸車A2の車輪21にも、押圧力は及ぼされていないので、その車輪21は上向きに最も突出した状態にある。
【0031】
この様な状態にある網戸100を窓枠に嵌め込むには、先ず、網戸100の下側の戸車A1の車輪21を、床面等の平坦面に押し当てると、車輪21が、図11に示した様に、車輪支持アーム20と共に最も押し上げられた状態になる。
丁度その時、下向きに回動付勢されている揺動爪32の先端のフツク32aが、車輪支持アーム20の掛止孔22に引っ掛かる。
【0032】
その為、車輪21及び車輪支持アーム20を、走行レール200から最も遠ざけた位置に固定させることが出来る。
そして、更に、レバー状ロッド41の摘み42を、前記とは逆向きに90度回動させると、縦向状態から横向状態に変わった折曲部41aが、ベースブロック10に設けた掛止溝に引っ掛かって、揺動爪32の回動は完全に阻止される。
【0033】
そこで、網戸100を持ち上げて、図1の上側に示した様に、上側の戸車A2の車輪21を、窓枠の上縁側に取付けた走行レール200に押し当てると、車輪支持アーム20が下向きに屈曲されて、その分、網戸100を更に持ち上げることが出来る。
【0034】
この時、下側の戸車A1の車輪21は、既述の様に押上状態に固定されているので、網戸100の下側を、窓枠の中に押し込もうとする時に、車輪21が、走行レール200にぶつかってしまう不具合は全く生じない。
そこで、網戸100を支持していた手を離せば、押上状態のままの車輪21を走行レール200に嵌め合わせることが出来る。
この時、上側の戸車A2の車輪21は、車輪支持アーム20のバネ作用力により、その走行レール200に圧接状態のままでで押し上げられる。
【0035】
次に、レバー状ロッド41の摘み42を、前方に押しやると、今迄、車輪支持アーム20の掛止孔22に引っ掛かっていた、揺動爪32のフック32aが孔から押し出される。
その為、車輪支持アーム20は、車輪21を走行レール200に向けて常時押圧する付勢力が回復して、窓枠への網戸100の嵌込作業は支障無く迅速に完了する。
【0036】
窓枠に嵌め込み終えた網戸100は、その上下の四隅に取付けてある、計4箇の戸車Aの夫々の車輪21が、車輪支持アーム20のバネ作用力によって上下の走行レール200に弾力的に圧接された状態になる。
その為、軽量で華奢に作られている網戸100が、その開け閉めの際のはずみで、ガタ付く様にギゴチなく動いたり、枠組が歪んだりしても、網戸100が窓枠から外れてしまう恐れはほぼ確実に無くなる。
【0037】
更に言えば、網戸100の枠組が歪み変形していたり、窓枠が幾分傾いている等の為に、窓枠と網戸100の枠組との間に、蚊等の害虫の侵入口となる隙間が出来る状態にあっても、網戸100の上下の四隅箇所に配置されているバネ材製の4箇の車輪支持アーム20が共同して、この隙間を埋め合わせる様に作用してくれる。
【0038】
次に、シーズンオフとなり、不要になった網戸を取り外す時には、走行レール200に向けて押圧付勢されたままの、下側の戸車A1の車輪21が、この取外作業を妨げることになる。
そこで、レバー状ロッド41の摘み42を廻して、折曲部41aを下向き位置に変位させると、揺動爪32の回動阻止状態が解除される。
【0039】
この状態では、網戸100の重みで車輪21及び車輪支持アーム20をその上限位置に迄押し上げて、既述の様に、揺動爪32のフック32aを、車輪支持アーム20の掛止孔22に掛止させ、押上状態に固定させることが出来る。
従って、下側の戸車A1の車輪21に邪魔されることなく、網戸100をスームズに窓枠から取り外すことが出来る。
【0040】
【発明の効果】
以上の説明によって明らかな様に、本発明による網戸用の戸車は、既存品に比べて以下に列挙した如き実用上のより優れた機能を発揮してくれる。
(a) 車輪には、走行レールへの圧接力が常時作用しているので、網戸の開閉時に、軽量で撓み変形し易い網戸が、窓枠から外れてしまう恐れがほぼ完全に無くなる。
(b) 戸車の上下の四隅の夫々に戸車を取付ければ、背丈の高い網戸でも、この外れ防止効果は完璧になる。
(c) 従って、高層階から落下して来た網戸が、下方の人や物を傷付けるといった重大事故が発生する懸念も解消する。
(d) 網戸を窓枠に取り付け、又、取り外す時には、車輪を走行レールから最も隔てさせた位置に仮固定する手段を設けてあるので、何等の支障も無く極めてスムーズに取付・取外を行える。
(e) 戸車は完全な一体構造に作られているので、網戸への取付けも簡単・迅速に行える。
(f) 構造が比較的簡素なので、製作費や耐久性等の点でも優れている。

TECHNICAL FIELD OF THE INVENTION
The present invention is a conventional problem that the screen door is disengaged from the window frame when it is opened and closed, or the screen door cannot be moved smoothly, or if measures are taken to prevent the screen door from being removed, the screen door cannot be easily removed when the screen door is removed. The present invention relates to a door door for a screen door improved so as to substantially eliminate the points, and a screen door to which the door door is attached.
[0002]
[Prior art]
FIGS. 12A and 12B are partial views showing a state in which a door roller 70 having a conventional general structure is attached to a screen door 100. FIG. 12A is a transparent front view, and FIG. 12B is a bottom view.
In the door roller 70, a main body block 72 on which wheels 71 are assembled is fixed to a vertical frame 100a of a screen door by a set screw 73. Reference numeral 74 denotes a position adjusting screw for finely adjusting the position of the wheel 71 up and down.
The bearing member 75 of the wheel 71 is fixed at the position where the adjustment has been completed. 100b is a horizontal frame of a screen door, 100c is an insect-proof net, and 200 is a running rail on which wheels 71 are mounted.
[0003]
As described above, in the conventional screen door 100 in which the bearing member 75 of the wheel 71 is fixedly mounted on the framework, the wheel 71 tends to easily come off the traveling rail 200 when the door is opened and closed. In addition, it was difficult to open and close the screen door 100 smoothly.
This is especially true for screen doors whose height is too high compared to their width.
It is even more so if the building is old and the standing is poor.
[0004]
In this way, the wheels 71 are easily detached from the traveling rail 200 and the screen door 100 cannot be moved smoothly because the frame of the screen door 100 is light and delicate, so that the screen door 100 swings up and down when opening and closing. It is because it moves and the framework tends to be distorted.
Alternatively, the above-mentioned malfunction may be caused by the frame of the screen 100 being deformed over time, the window frame not being made accurately, or being deformed over time.
[0005]
The screen door that is easily detached from the window frame must be re-inserted each time it comes off, which is extremely time-consuming.
In the case of the elderly, further improvement of this problem is desired.
Not only that, if the screen door falls off from a room in a tall building with more than two stories, if a person happens to be on the ground directly underneath, a serious situation may occur.
In view of this, a door roller has been devised in which the wheels of the door roller are constantly pressed against the rail by a spring force.
Alternatively, there is a type in which a member for preventing detachment is attached to the upper frame of the screen door.
[0006]
[Problems to be solved by the invention]
However, in order to prevent the screen door once fitted into the window frame from being accidentally detached as described above, the more you try to attach it as tightly as possible, the more difficult it is to remove the screen door I was invited.
Further, the conventional door roller that has taken measures to prevent the screen door from coming off has much room for improvement in terms of manufacturing cost, durability, labor for installation, and the like.
[0007]
Therefore, an object of the present invention is to almost certainly eliminate the danger that the screen door will fall out of the window frame due to the bounce at the time of opening and closing, and of course, the screen door can be easily and quickly removed.

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a partial front view showing a main part of a screen door 100 to which a door roller A according to the present invention is attached.
100a and 100b in the figure are the left and right vertical frames and the upper and lower horizontal frames that constitute the frame of the screen door 100, and 100c is an insect-proof net stretched over the frame.
[0011]
Accordingly, the door 100 is attached to the door 100 at a total of four locations on the left and right sides on the lower and upper ends of the screen door 100.
However, the upper two door rollers A2 shown in FIG. 1 have a mechanism for facilitating the work of removing the screen door 100 once fitted into the window frame from the window frame when the season is off, as described later. Is different from the two doors A1 on the lower side.
Except for this difference, the basic structures of the door cars A1 and A2 are common.
[0012]
Therefore, the specific structure of the lower door car A1 will be sequentially described below.
2 and 3 are a front view and a transparent front view of the door roller A1, and FIG. 4 is a front view showing only a main body portion of the door roller A1 and four vertical and horizontal views thereof.
FIG. 5 is an exploded perspective view of a main part of the door roller A1, and FIG. 6 is a perspective view showing an assembled state thereof.
[0013]
FIG. 7 is an exploded front view of a spring force adjusting mechanism for adjusting a spring force of a wheel support arm 20 made of a leaf spring, which will be described later, and a perspective view of a slider. FIG. It is a front view and a side view.
FIG. 9 is a perspective view showing the structure of an arm fixing / fixing releasing means for restricting the vertical movement of the wheel supporting arm 20, and FIG. It is a front view.
FIG. 11 is an operation explanatory view of the door roller A1.
[0014]
As shown in FIGS. 2 and 3, the schematic configuration of the door roller A <b> 1 has a base block 10 screwed to the vertical frame 100 a of the screen door 100, and a base end side thereof fixed to the base block 10, and A wheel support arm 20 made of a leaf spring, to which the wheel 21 is attached, an arm fixing means 30 for fixing the wheel 21 at a position farthest from the running rail 200, and a fixing releasing means 40 are provided. .
[0015]
First, as shown in FIGS. 1 to 6, the base block 10 includes a vertical block 12 fixed to the vertical frame 100 a by a set screw 11 and a horizontal block 13 to be in contact with the lower surface of the vertical frame 100 b. It has an L-shaped connection.
Two bearing plates 14, 14 each having a shaft hole are vertically provided on the distal end side of the horizontal block 13 so as to face each other.
4 to 6, the bearing plate 14 on the near side is shown in a flipped up state so that the structure can be easily understood.
[0016]
Next, the wheel support arm 20 is made of a band-shaped spring material, and has a horizontal portion 20a with its base end (right end in the figure) bent upward to form a rising portion 20b, and a set screw 11 and the like. There are two upper and lower bottle holes through which the water passes.
Two bearing plates 20c provided with shaft holes through which the axles of the wheels 21 pass are provided vertically at the distal end side of the horizontal portion 20a so as to face each other.
[0017]
Therefore, even if the screen door 100 supported by both hands is moved up and down while the wheel 21 is placed on the traveling rail 200, the wheel 21 exerts the spring acting force of the wheel support arm 20 within a predetermined vertical movement height range. Accordingly, the pressure contact state is always kept on the traveling rail 200. Along with this, the wheel support arm 20 is bent up and down as shown in FIG.
[0018]
Further, in the horizontal portion 20a of the wheel supporting arm 20, as shown in FIG. 5 and the like, a hook hole 22 for hooking a hook 32a of a swinging claw 32 described later is provided near a tip thereof. It is provided upward.
[0019]
A spring force adjusting mechanism 50 for adjusting the spring acting force is also attached to the wheel supporting arm 20 made of a spring material.
The spring force adjusting mechanism 50 includes a slider 51 slidable left and right along the lower surface side of the horizontal block 13 of the base block 10 as shown in FIGS. A push / pull screw 52 and a coil spring 53 fitted externally to the push / pull screw 52 are provided.
[0020]
As shown in FIG. 3, the horizontal portion 20 a of the wheel support arm 20 is arranged in parallel so as to face the lower surface of the horizontal block 13, and the slider 51 is horizontally aligned with the lower surface of the horizontal block 13. It is in a state of being sandwiched between the portion 20a.
Therefore, the contact point of the vertically movable wheel supporting arm 20 with the front edge of the lower surface of the slider 51 becomes a fulcrum at the time of the bending movement (see FIG. 11).
[0021]
The push / pull screw 52 is inserted from the outside into an insertion hole provided in the vertical block 12, and its tip is screwed into a screw hole 51 a provided in the slider 51.
The coil spring 53 is externally fitted to the push / pull screw 52 while being sandwiched between the vertical block 12 and the slider 51.
As shown in FIG. 1, the wheel support arm 20 is disposed such that the wheel 21 is constantly pressed against the traveling rail 200 by the spring force in a state where the screen door 100 is fitted in the window frame. .
[0022]
Therefore, if the position of the slider 51 is displaced right and left by rotating the push / pull screw 52 forward and backward, the fulcrum of the wheel support arm 20 fluctuates, and the spring action force is adjusted accordingly. You can do it.
Since the bearing plate 20c provided on the wheel support arm 20 prevents the arm from bending, it is necessary to determine the position and shape of the bearing plate 20c so as not to approach the slider 51 too much.
[0023]
Next, as shown in FIG. 5, FIG. 6, and FIG. 9 to FIG. 11, the arm fixing means 30 is attached to a support shaft 31 attached to the bearing plates 14 of the base block 10 at the base end thereof. A swinging claw 32 pivotally supported on its side and swingable up and down, and a hook 32 a provided downward at the tip of the swinging claw 32 are detachably engaged with the tip of the wheel support arm 20. It has a configuration in which the provided hook holes 22 are combined.
A coil spring 33 for urging the swinging claw 32 to rotate downward is attached to the support shaft 31.
[0024]
The fixing releasing means 40 of the wheel supporting arm 20 is provided between the vertical block 12 of the base block 10 and the swinging claw 32 as the arm fixing means 30, as shown in FIGS. The lever-shaped rod 41 that is rotatable around its axis and that can move back and forth in the axial direction is used as its main body.
[0025]
As shown in FIG. 9, the distal end side of the lever-shaped rod 41 is mounted on a locking groove provided on the swinging claw 32, and its protruding end is bent at a right angle to form a bent portion 41a. I have.
Then, as shown in FIG. 3, the base end side of the lever-shaped rod 41 is projected outward through an insertion hole provided in the vertical block 12, and a knob 42 is attached to the projected end.
[0026]
Next, the structure of the door roller A2 attached to the upper end of the screen door 100 is the same as the lower door roller A1 except that the arm fixing means 30 and the fixing releasing means 40 are omitted as described above. Will be omitted.
Since the upper door roller A2 has a smaller load than the lower door roller A1, the diameter of the wheels 21 is made smaller accordingly.
[0027]
Next, the operation of the door roller A1 will be described.
In this embodiment, as described above, door rollers A1 or A2 are attached to the upper and lower four corners of the screen door 100, respectively.
However, if the screen door is short, it can be opened and closed more smoothly than a vertically long screen door, so the door roller A according to the present invention is not necessarily required.
The method of attaching the door roller A to the screen door 100 is as described above.
[0028]
First, prior to fitting the screen door 100 into a window frame (not shown), the knob 42 of the lever-shaped rod 41 of the door roller A1 is rotated to show the bent portion 41a in FIG. 9B. In the downward pivot position.
In this state, the swinging claw 32 urged downward by the coil spring 33 is not obstructed by the bent portion 41a.
[0029]
When the screen door 100 is lifted to fit the screen door 100 into the window frame, no pressing force is exerted on the wheels 21, so that the wheel support arm 20 in the no-load state is as shown in FIG. It extends straight and horizontally.
At this time, the wheel 21 is in a state of protruding most downward (see FIG. 11).
[0030]
On the other hand, since no pressing force is applied to the wheel 21 of the door roller A2 attached to the upper end of the screen door 100, the wheel 21 is in the state of being most protruded upward.
[0031]
In order to fit the screen door 100 in such a state into the window frame, first, the wheels 21 of the door roller A1 below the screen door 100 are pressed against a flat surface such as a floor, and the wheels 21 are turned into FIG. As shown, it is in the state of being pushed up most together with the wheel support arm 20.
At that time, the hook 32 a at the tip of the swinging claw 32 that is urged to rotate downward is hooked into the hook hole 22 of the wheel support arm 20.
[0032]
Therefore, the wheel 21 and the wheel support arm 20 can be fixed at a position farthest from the traveling rail 200.
When the knob 42 of the lever-shaped rod 41 is further rotated by 90 degrees in the opposite direction to the above, the bent portion 41a that has changed from the vertical state to the horizontal state has a locking groove provided in the base block 10. , The rotation of the swing claw 32 is completely prevented.
[0033]
Therefore, when the screen door 100 is lifted and the wheels 21 of the upper door roller A2 are pressed against the traveling rail 200 attached to the upper edge of the window frame as shown in the upper part of FIG. 1, the wheel support arm 20 is turned downward. The door 100 is bent, and the screen door 100 can be further lifted.
[0034]
At this time, since the wheel 21 of the lower door roller A1 is fixed in the pushed up state as described above, when the lower side of the screen door 100 is to be pushed into the window frame, the wheel 21 The trouble of hitting the traveling rail 200 does not occur at all.
Then, if the hand supporting the screen door 100 is released, the wheel 21 in the pushed-up state can be fitted to the traveling rail 200.
At this time, the wheel 21 of the upper door roller A2 is pushed up by the spring action force of the wheel support arm 20 while being pressed against the traveling rail 200.
[0035]
Next, when the knob 42 of the lever-shaped rod 41 is pushed forward, the hook 32a of the swinging claw 32, which has been hooked on the hook hole 22 of the wheel support arm 20, is pushed out of the hole.
Therefore, the urging force of the wheel support arm 20 that constantly presses the wheel 21 toward the traveling rail 200 recovers, and the work of inserting the screen door 100 into the window frame is quickly completed without any trouble.
[0036]
The screen door 100, which has been fitted into the window frame, has the wheels 21 of the four door wheels A attached to the four upper and lower corners thereof elastically attached to the upper and lower running rails 200 by the spring action force of the wheel support arm 20. It will be in a pressed state.
For this reason, the screen door 100, which is made light and delicate, moves when it is opened and closed, moves without rattling as if rattling, or the frame is distorted, so that the screen door 100 comes off the window frame. Fear is almost certainly gone.
[0037]
Furthermore, since the frame of the screen 100 is distorted or deformed, or the window frame is slightly inclined, the gap between the window frame and the frame of the screen 100 becomes an entrance for a pest such as a mosquito. Even in the state where the vehicle door 100 can be formed, the four wheel support arms 20 made of spring material disposed at the four upper and lower corners of the screen door 100 work together to fill this gap.
[0038]
Next, when the screen door is removed after the season has ended and is no longer needed, the wheel 21 of the lower door roller A1, which is kept pressed and urged toward the traveling rail 200, hinders the removal operation.
Then, when the knob 42 of the lever-shaped rod 41 is turned to displace the bent portion 41a to the downward position, the rotation preventing state of the swinging claw 32 is released.
[0039]
In this state, the weight of the screen door 100 pushes up the wheel 21 and the wheel support arm 20 to the upper limit position, and the hook 32 a of the swinging claw 32 is inserted into the hook hole 22 of the wheel support arm 20 as described above. It can be hooked and fixed in the push-up state.
Therefore, the screen door 100 can be smoothly removed from the window frame without being disturbed by the wheels 21 of the lower door roller A1.
[0040]
