Description

本発明は、網戸の外れ止め装置に関し、詳しくは、網戸の開閉時に網戸が上方に浮き上がって網戸の下部が下部レールから外れてしまうことを防止するための網戸の外れ止め装置に関する。 The present invention relates to a screen door slip-off preventing device, and more particularly to a screen door slip-off preventing device for preventing the screen door from floating upward when the screen door is opened and closed and the lower portion of the screen door coming off the lower rail.

上記網戸の外れ止め装置では、例えば網戸の上框の上部水平板部の上面から上方に伸びる室外側の上部突出部材と室内側の上部突出部材とを備え、前記一対の上部突出部材の間に上部レールが位置する状態で網戸を配置し、前記上框の上部水平板部に形成されている貫通孔に差し込まれて突出部材間に位置する弾性部材からなる外れ止め部材を備え、網戸の移動時に発生する上下振動により上方へ浮き上がろうとすることを、外れ止め部材が上部レールに接当することによって阻止されて網戸の下端が下部レールから外れることを阻止するようにしている。そして、前記外れ止め部材に、上部水平板部に形成の貫通孔に係止する鋸歯状突起を上下方向に形成してあり、上部レールの下端面に外れ止め部材をできるかぎり近づけた状態になるように上部水平板部に対して外れ止め部材を上下方向で位置変更自在に構成している（例えば、特許文献１参照）。
特開２００１−２０６４０号公報（第６図、第７図参照） The screen door detachment preventing apparatus includes, for example, an outdoor upper projecting member and an indoor upper projecting member extending upward from the upper surface of the upper horizontal plate portion of the upper screen of the screen door, and between the pair of upper projecting members. The screen door is arranged in a state where the upper rail is located, and the screen door is provided with an anti-slip member made of an elastic member that is inserted into the through hole formed in the upper horizontal plate portion of the upper collar and located between the protruding members. Attempts to float upward due to vertical vibrations that are sometimes generated are prevented by the anti-separation member coming into contact with the upper rail, and the lower end of the screen door is prevented from coming off the lower rail. And the serration-like protrusion which latches to the through-hole formed in the upper horizontal board part is formed in the up-and-down direction in the above-mentioned anti-stop member, and it comes in the state where the anti-stop member was brought as close as possible to the lower end surface of the upper rail Thus, the anti-separation member is configured to be freely changeable in the vertical direction with respect to the upper horizontal plate (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2001-20640 (see FIGS. 6 and 7)

上記特許文献１の外れ止め部材では、上部レールの下面と外れ止め部材の上面との間に隙間が発生してしまうため、網戸の開閉移動中に上下動しながら移動する網戸の外れ止め部材の上端が上部レールに頻繁に接当してしまうため、接当による異音発生の原因になるだけでなく、上部レールと接当しながらの網戸の移動は、スムーズさに欠けるものであった。
又、前記接当を回避するために、上部レールの下面と外れ止め部材の上面との間に隙間が発生しないように、外れ止め部材を上部レールに接当する位置まで上方へ移動させておくことが考えられるが、開閉移動中に網戸が上方に移動したときに上部レールに外れ止め部材が食い込むような力が外れ止め部材に作用してしまうため、その力が網戸の移動抵抗になり、網戸を軽快に移動させることができなくなり、その結果、前述のように上部レールの下面と外れ止め部材の上面との間に隙間が発生する状態にすることになり、改善の余地があった。 In the anti-slip member of Patent Document 1, a gap is generated between the lower surface of the upper rail and the upper surface of the anti-skid member. Therefore, the anti-skid member of the screen door that moves while moving up and down during the opening and closing movement of the screen door is provided. Since the upper end frequently contacts the upper rail, it not only causes abnormal noise due to the contact, but also the movement of the screen door while contacting the upper rail is not smooth.
In order to avoid the contact, the stopper member is moved upward to a position where it comes into contact with the upper rail so that there is no gap between the lower surface of the upper rail and the upper surface of the stopper member. However, when the screen door moves up and down during opening and closing movement, the force that the stopper member bites into the upper rail acts on the stopper member, so that force becomes the movement resistance of the screen door, The screen door cannot be moved lightly, and as a result, a gap is generated between the lower surface of the upper rail and the upper surface of the locking member as described above, and there is room for improvement.

本発明が前述の状況に鑑み、解決しようとするところは、移動時において網戸が外れてしまうことを防止しながらも、異音発生がなく、スムーズかつ軽快に移動させることができる網戸の外れ止め装置を提供する点にある。 In view of the above-mentioned situation, the present invention intends to solve the problem that the screen door is prevented from coming off at the time of movement, but is free from abnormal noise and can be moved smoothly and lightly. The point is to provide a device.

本発明の網戸の外れ止め装置は、前述の課題解決のために、サッシ枠を構成する上部枠の上部レールの室内側又は室外側に、網戸の上框から上方に延びる垂直片部をそれの上端が該上部レールの下端よりも上方に位置する状態で配置し、前記上部レールの室外側又は室内側に位置し、該上部レールの下端よりも上方に上端が位置して前記網戸の外れ止めを行う複数の外れ止め部材を前記網戸の上框に備え、前記各外れ止め部材を、前記上部レールの下端よりも上方に上端が位置する外れ止め作用位置と該上部レールの下端よりも上端が下方に位置して該網戸の外れ止めを解除する外れ止め解除位置とに渡って上下位置変更自在に構成し、前記外れ止め部材を、水平軸芯周りで上下揺動自在で、かつ、弾性部材により前記外れ止め作用位置へ揺動付勢された揺動アームと、前記揺動アームに前記上部レール側に突出する状態で備えられ、かつ、該揺動アームの上方側への揺動に伴って前記上部レールの下端に押し付けられる押圧部とから構成し、前記外れ止め部材の下端に接当して該外れ止め部材の下方側への移動を阻止するための接当部材を備え、前記接当部材を、前記外れ止め部材の下方に位置して該外れ止め部材の下方側への接当位置を上下方向で変更させるためにスライド自在に構成した接当部本体と、前記接当部本体を複数のスライド位置にて保持させるための保持手段とから構成したことを特徴としている。
又、網戸の下框に、サッシ枠を構成する下部枠の下部レールの室内側及び室外側の両側に位置して該網戸の外れ止めを行うための外れ止め部をそれの下端が該下部レールの上端よりも下方に位置する状態で備え、前記網戸の移動時に該網戸の浮き上がりにより前記外れ止め部を乗り越えて該網戸が外れてしまうことがないように前記サッシ枠を構成する上部枠の上部レールの下端に接当して該網戸の浮き上がりを規制するための押圧部材を複数備えさせ、前記各押圧部材を、水平軸芯周りで上下揺動自在で、かつ、前記上部レールの下端に押し付け付勢するために上方側へ揺動付勢し、前記押圧部材の下端に接当して該押圧部材の下方側への移動を阻止するための接当部材を備え、前記接当部材を、前記押圧部材の下方に位置して該押圧部材の下方側への接当位置を上下方向で変更させるためにスライド自在に構成した接当部本体と、前記接当部本体を複数のスライド位置にて保持させるための保持手段とから構成してもよい。
外れ止め部材が外れ止め作用位置に揺動付勢されているから、網戸を開閉するために移動することによって、上下動する網戸に追従して外れ止め部材が上下動する、つまり網戸が上方側へ移動するときは外れ止め部材は下方側へ揺動し、網戸が下方側へ移動するときは外れ止め部材は上方側へ揺動することができるから、上部レールの下端に揺動アームに備えた押圧部が常に接当しながら、網戸を移動させることができ、しかも、押圧部の上下動が網戸に移動抵抗となることがなく、網戸をスムーズかつ軽快に移動させることができる。そして、移動時に網戸が不測に大きく浮き上がった場合には、下方側へ揺動する外れ止め部材の下端が接当部材に接当することによって、外れ止め部材の下方側への揺動が阻止され、網戸が外れることを阻止することができる。尚、外れ止め部材に対する接当部材のスライド位置は、上部レールの下端と網戸の上框の上端との隙間の大きさに応じて変更することになる。
又、網戸下框に備えている外れ止め部とサッシ枠の下部レールとの係り代以上に網戸が浮き上がることを、上部レールの下端に接当する押圧部材の上下位置を接当部材にて調節することによって、回避して網戸が外れることを確実に防止することができる。 In order to solve the above-mentioned problems, the screen door slip-off device of the present invention has a vertical piece extending upward from the top of the screen door on the indoor side or the outdoor side of the upper rail of the upper frame constituting the sash frame. Arranged in a state where the upper end is located above the lower end of the upper rail, located on the outdoor side or indoor side of the upper rail, the upper end is located above the lower end of the upper rail, and prevents the screen door from coming off. A plurality of anti-slip members are provided on the upper arm of the screen door, and each anti-slip member is provided with a anti-skid position where the upper end is positioned above the lower end of the upper rail and the upper end of the upper rail is lower than the lower end of the upper rail. It is configured to be able to change the vertical position over a position where the screen door is released and to prevent the screen door from coming off, and the elastic member is capable of swinging up and down around the horizontal axis. To the position to prevent The oscillating arm is urged, and is provided in a state in which the oscillating arm protrudes toward the upper rail, and is pressed against the lower end of the upper rail as the oscillating arm swings upward. A pressing portion, and a contact member for contacting the lower end of the locking member to prevent the locking member from moving downward, wherein the locking member is connected to the locking member. A contact part body configured to be slidable so as to change the contact position of the stopper member to the lower side in the up and down direction, and to hold the contact part body at a plurality of slide positions. It is characterized by comprising a holding means.
Further, the lower end of the screen door is provided with a stopper for preventing the screen door from being located on both the indoor side and the outdoor side of the lower rail of the lower frame constituting the sash frame. An upper portion of the upper frame constituting the sash frame so that the screen door does not come off when the screen door is moved and the screen door is lifted to overcome the slip-off preventing portion when the screen door is moved. Provided with a plurality of pressing members that come into contact with the lower end of the rail to restrict the lifting of the screen door, and each pressing member can swing up and down around a horizontal axis and is pressed against the lower end of the upper rail A biasing member that swings and biases upward in order to bias, and is in contact with the lower end of the pressing member to prevent the pressing member from moving downward; The pressing member is located below the pressing member. A contact portion main body configured to be slidable so as to change the contact position on the lower side in the vertical direction, and a holding means for holding the contact portion main body at a plurality of slide positions. Good.
Since the anti-slip member is oscillated and biased to the anti-skid action position, the anti-skid member moves up and down following the screen door that moves up and down by moving to open and close the screen door. The anti-separation member swings downward when moving to the lower side, and when the screen door moves downward, the anti-separation member can swing upward. The screen door can be moved while the pressing portion is always in contact, and the vertical movement of the pressing portion does not cause movement resistance to the screen door, and the screen door can be moved smoothly and lightly. When the screen door is lifted unexpectedly and large during movement, the lower end of the locking member that swings downward contacts the contact member, thereby preventing the locking member from swinging downward. It is possible to prevent the screen door from coming off. In addition, the sliding position of the contact member with respect to the come-off preventing member is changed according to the size of the gap between the lower end of the upper rail and the upper end of the upper arm of the screen door.
The vertical position of the pressing member that contacts the lower end of the upper rail is adjusted by the contact member so that the screen door is lifted more than the allowance between the stopper provided on the screen door and the lower rail of the sash frame. By doing so, it is possible to reliably prevent the screen door from coming off.

前記外れ止め部材及び前記接当部材を、前記網戸の上框に支持される支持部材に取り付け、前記接当部材の接当部本体の被接当側端に前記支持部材から外部に延出されて該接当部本体をスライドさせるための押し引き用の操作レバー部を備えてもよい。 The detachment prevention member and the contact member are attached to a support member supported by an upper arm of the screen door, and are extended outward from the support member to a contact side end of a contact portion main body of the contact member. An operation lever portion for pushing and pulling for sliding the contact portion main body may be provided.

前記保持手段を、前記接当部本体にそれのスライド方向に所定間隔を隔てて複数箇所に備えた凸部又は凹部と、これら複数の凸部又は凹部に係止して複数のスライド位置で前記接当部材を保持するために前記支持部材に備えた単数又は複数の凹部又は凸部とから構成してもよい。 The holding means is provided with a plurality of convex portions or concave portions provided at a plurality of positions at predetermined intervals in the sliding direction of the contact portion main body, and the plurality of convex portions or concave portions are engaged with the plurality of sliding positions at the slide positions.

The support member may be provided.

前記押圧部の押圧面を円弧形状に構成してもよい。 You may comprise the press surface of the said press part in circular arc shape.

前記上部レールの室内側又は室外側に、網戸の上框から上方に延びる垂直片部をそれの上端が該上部レールの下端よりも上方に位置する状態で配置し、前記上部レールの室外側又は室内側に位置し、該上部レールの下端よりも上方に上端が位置して前記網戸の外れ止めを行う外れ止め部材を、前記押圧部材の室外側又は室内側に該押圧部材と一体的に揺動自在に備えさせてもよい。 A vertical piece extending upward from the upper end of the screen door is disposed on the indoor side or the outdoor side of the upper rail in a state where the upper end thereof is located above the lower end of the upper rail, A slip-off preventing member that is located on the indoor side and that has an upper end located above the lower end of the upper rail and prevents the screen door from coming off is rocked integrally with the pressing member on the outdoor side or indoor side of the pressing member. You may make it move freely.

外れ止め部材を外れ止め作用位置に揺動付勢する構成とすることによって、網戸を開閉するために移動したときに、上下動する網戸に追従して外れ止め部材を上下動させることができるから、上部レールの下端に揺動アームに備えた押圧部が常に接当しながら、網戸を移動させることができ、接当による異音発生がなく、しかも網戸をガタツキ無くスムーズかつ軽快に移動させることができる使用面において有利な網戸の外れ止め装置を提供することができる。そして、移動時に網戸が不測に大きく浮き上がった場合には、下方側へ揺動する外れ止め部材の下端が接当部材に接当することによって、外れ止め部材の下方側への揺動が阻止され、網戸が外れることを確実に阻止することができ、信頼性の高い網戸の外れ止め装置とすることができる。又、外れ止め機能を有する前記外れ止め部材と網戸の開閉時のガタツキ防止機能を有する押圧部とを一体化することによって、組み付け作業面において非常に安価になる。特に外れ止め部材と押圧部とを一体形成する場合には、別々に製造する場合に比べて材料コストにおいても安価になる。
又、網戸の移動時に網戸の浮き上がりにより外れ止め部を乗り越えて網戸が外れてしまうことがないようにサッシ枠を構成する上部枠の上部レールの下端に接当して網戸の浮き上がりを規制するための押圧部材を複数備えさせることによって、網戸の移動時に、網戸下框に備えている外れ止め部とサッシ枠の下部レールとの係り代以上に網戸が浮き上がって、網戸が外れてしまうことを確実に阻止することができることは勿論のこと、前記と同様に、上部レールの下端に押圧部材が常に接当しながら、網戸を移動させることができ、接当による異音発生がなく、しかも網戸をガタツキ無くスムーズかつ軽快に移動させることができる使用面において有利な網戸の外れ止め装置を提供することができる。
又、前記外れ止め部材や押圧部材を水平軸芯周りで上下揺動させるとともに、水平方向で移動する接当部材との接当により外れ止め部材や押圧部材の上下位置を変更する構成とすることによって、外れ止め部材や押圧部材を上下方向に移動させる構成に比べて、上下方向でのスペースを小さくすることができ、設計の自由度を高めることができる。
前記外れ止め部材や押圧部材の上下位置調節を行う理由として、サッシの上下枠の施工による誤差の他、網戸やサッシの製作誤差を吸収するためである。 By adopting a configuration that swings and biases the slip-off preventing member to the slip-off preventing position, it is possible to move the slip-off preventing member up and down following the screen door that moves up and down when moving to open and close the screen door. The screen door can be moved while the pressing part of the swing arm is always in contact with the lower end of the upper rail, there is no abnormal noise due to contact, and the screen door can be moved smoothly and lightly without rattling. Therefore, it is possible to provide a screen door slip-off preventing device that is advantageous in terms of use. When the screen door is lifted unexpectedly and large during movement, the lower end of the locking member that swings downward contacts the contact member, thereby preventing the locking member from swinging downward. Therefore, it is possible to reliably prevent the screen door from coming off, and it is possible to provide a reliable screen door slip-off device. Further, by integrating the above-described anti-separation member having the anti-separation function and the pressing portion having an anti-rattle function at the time of opening and closing the screen door, the assembling work surface becomes very inexpensive. In particular, when the anti-separation member and the pressing portion are integrally formed, the material cost is reduced as compared with the case where they are manufactured separately.
In addition, to prevent the screen door from rising by contacting the lower end of the upper rail of the upper frame constituting the sash frame so that the screen door does not come off due to the screen door floating due to the screen door moving up. By providing a plurality of pressing members, it is ensured that when the screen door is moved, the screen door will be lifted up more than the engagement between the screen stopper and the lower rail of the sash frame. Of course, in the same way as described above, the screen door can be moved while the pressing member is always in contact with the lower end of the upper rail. It is possible to provide a screen door slip-off preventing device that is advantageous in terms of use and can be moved smoothly and lightly without rattling.
Further, the stopper member and the pressing member are swung up and down around the horizontal axis, and the vertical position of the stopper member and the pressing member is changed by contact with the contact member moving in the horizontal direction. Therefore, the space in the vertical direction can be reduced and the degree of freedom in design can be increased as compared with the configuration in which the stopper member and the pressing member are moved in the vertical direction.
The reason for adjusting the vertical position of the detachment prevention member and the pressing member is to absorb the manufacturing error of the screen door and the sash in addition to the error due to the construction of the upper and lower frames of the sash.

前記外れ止め部材及び前記接当部材を、前記網戸の上框に支持される支持部材に取り付け、前記接当部材の接当部本体の被接当側端に前記支持部材から外部に延出されて該接当部本体をスライドさせるための押し引き用の操作レバー部を備えさせることによって、支持部材を網戸の上框に取り付けるだけで、外れ止め部材及び接当部材を網戸に装着することができる。しかも、支持部材から外部に延出された操作レバー部を直ちに押し引き操作するだけで接当部本体を迅速にスライド（移動）させることができる。 The detachment prevention member and the contact member are attached to a support member supported by an upper arm of the screen door, and are extended outward from the support member to a contact side end of a contact portion main body of the contact member. By providing an operation lever portion for pushing and pulling for sliding the contact portion main body, it is possible to attach the stopper member and the contact member to the screen door only by attaching the support member to the upper arm of the screen door. it can. Moreover, the abutment portion main body can be quickly slid (moved) by simply pushing and pulling the operation lever portion extended to the outside from the support member.

前記保持手段を、前記接当部本体にそれのスライド方向に所定間隔を隔てて複数箇所に備えた凸部又は凹部と、これら複数の凸部又は凹部に係止して複数のスライド位置で前記接当部材を保持するために前記支持部材に備えた単数又は複数の凹部又は凸部とから構成することによって、接当部本体をスライドさせるだけで、凸部と凹部とを係止させて接当部本体を任意のスライド位置にて保持させることができ、螺子などを用いて固定及び固定解除する構成に比べて、接当部本体のスライド位置変更操作を迅速に行うことができる。 The holding means is provided with a plurality of convex portions or concave portions provided at a plurality of positions at predetermined intervals in the sliding direction of the contact portion main body, and the plurality of convex portions or concave portions are engaged with the plurality of sliding positions at the slide positions. By comprising one or a plurality of concave portions or convex portions provided in the support member to hold the contact member, the convex portion and the concave portion can be locked and contacted by simply sliding the contact portion main body. The main part of the contact part can be held at an arbitrary slide position, and the slide position changing operation of the main part of the contact part can be quickly performed as compared with a configuration in which the main part is fixed and released using a screw or the like.

前記網戸の上框を構成する水平の上壁部分に複数の貫通孔を形成し、それら貫通孔に前記支持部材を入り込ませて該貫通孔の外周縁に係止保持させるための係止部を該支持部材に備えさせることによって、支持部材を網戸の上框を構成する水平の上壁部分に形成の貫通孔に挿入して係止保持させるだけで、支持部材を取り付けることができる。 A plurality of through holes are formed in a horizontal upper wall portion that constitutes the upper arm of the screen door, and a locking portion is provided for allowing the support member to enter the through holes and locking and holding the outer peripheral edge of the through hole. By providing the support member, the support member can be attached simply by inserting the support member into a through-hole formed in the horizontal upper wall portion constituting the upper arm of the screen door, and holding the support member.

前記押圧部の押圧面を円弧形状に構成することによって、上部レールとの接触面積を小さくすることができ、その分網戸の移動時の上部レールとの摺接抵抗を小さくして、網戸の移動抵抗を小さくすることができる。 By configuring the pressing surface of the pressing portion in an arc shape, the contact area with the upper rail can be reduced, and the sliding contact resistance with the upper rail when moving the screen door is reduced accordingly, and the screen door moves. Resistance can be reduced.

図１に、サッシ枠を構成する上部枠１に、屋内側のガラス障子２及び屋外側のガラス障子３を備え、前記上部枠１の最も屋外側に位置する上部レール４に網戸５を備えた上側のみの縦断面図を示している。前記網戸５には外れ止め装置を備えさせており、この外れ止め装置は、前記上部レール４の室内側に、網戸５の上框６の上壁部分６Ａから室内側に延出された水平板部６Ｂから上方に延びる垂直片部７をそれの上端が該上部レール４の下端よりも上方に位置する状態で配置し、前記上部レール４の室外側に位置し、該上部レール４の下端よりも上端が上方に位置して前記網戸５の外れ止めを行う２個の外れ止め部材８（図では１個のみ図示）を前記網戸５の上框６の水平板部６Ｂに備えさせている。前記垂直片部７と前記外れ止め部材８とを図１とは反対の位置関係に配置してもよい。つまり、前記垂直片部７を上部レール４の室外側に配置し、前記外れ止め部材８を上部レール４の室内側に配置して実施してもよい。前記外れ止め部材８の２個を前記網戸５の上框６の網戸移動方向両側にそれぞれ振り分けて設けているが、外れ止め部材８を３個以上設けて実施することもできるが、個数が多くなればなるほど網戸５の外れ止め効果が大きくなるが、その分移動抵抗も大きくなるため、外れ止め部材８の２個を上框６の網戸移動方向両側にそれぞれ振り分けて設ける場合が最適である。ここでは、網戸５の上框６の上壁部分６Ａから室内側に延出された水平板部６Ｂから上方に延びる垂直片部７としているが、水平板部６Ｂの無いものであってもよい。この場合、上框６の上壁部分６Ａに前記外れ止め部材８を設けることになる。前記ガラス障子２，３の具体的構成は、図１に示されるものに限定されるものではなく、網戸５を装着するためのサッシ枠を備えるものであれば、どのような構成のものでも本発明は適応できる。 In FIG. 1, the upper frame 1 constituting the sash frame is provided with an indoor side glass shoji 2 and an outdoor side glass shoji 3, and the upper rail 4 located on the most outdoor side of the upper frame 1 is provided with a screen door 5. A vertical sectional view of only the upper side is shown. The screen door 5 is provided with a locking device, which is a horizontal plate extending from the upper wall portion 6A of the upper arm 6 of the screen door 5 to the indoor side of the upper rail 4 on the indoor side. The vertical piece portion 7 extending upward from the portion 6B is disposed with its upper end positioned above the lower end of the upper rail 4 and is positioned outside the upper rail 4 from the lower end of the upper rail 4. In addition, two horizontal stoppers 8 (only one is shown in the figure) are provided on the horizontal plate portion 6B of the upper screen 6 of the screen door 5 so as to prevent the screen door 5 from coming off. You may arrange | position the said vertical piece part 7 and the said locking member 8 in the positional relationship opposite to FIG. That is, the vertical piece 7 may be arranged outside the upper rail 4 and the anti-slip member 8 may be arranged inside the upper rail 4. Two of the anti-skid members 8 are provided separately on both sides of the screen door 5 in the moving direction of the screen 6 of the screen door 5, but can be provided with three or more anti-skid members 8 but the number is large. The more it is, the greater the effect of preventing the screen door 5 from coming off. However, since the movement resistance also increases accordingly, it is optimal to provide the two stopper members 8 separately on both sides of the upper door 6 in the screen door moving direction. Here, although it is set as the vertical piece part 7 extended upwards from the horizontal board part 6B extended from the upper wall part 6A of the upper arm 6 of the screen door 5 to the indoor side, the thing without the horizontal board part 6B may be sufficient. . In this case, the detachment preventing member 8 is provided on the upper wall portion 6A of the upper collar 6.

The invention is adaptable.

前記各外れ止め部材８を、それの上端（図では接当部１０Ｓの上面）が前記上部レール４の下端よりも上方に位置する外れ止め作用位置（図１、図２（ｂ）参照）と該上部レール４の下端よりも下方に位置して該網戸５の外れ止めを解除する外れ止め解除位置（図２（ａ）参照）とに渡って上下位置変更自在に構成している。詳述すれば、前記外れ止め部材８を、図１、図２（ａ），（ｂ）及び図３に示すように、後述する支持部材１５に貫通したピンＰにて水平軸芯Ｘ周りで上下揺動自在で、かつ、弾性部材の一例であるつる巻きバネ９により前記外れ止め作用位置へ揺動付勢された合成樹脂製で板状の揺動アーム１０と、前記揺動アーム１０の遊端に備えさせた外れ止め用の接当部１０Ｓの上面よりも下方に位置する上面を有し、前記上部レール４側に向けて水平方向に突出するように、該揺動アーム１０に一体成形され、かつ、該揺動アーム１０の上方側への揺動に伴って前記上部レール４の下端に押し付けられる合成樹脂製の押圧部１１とから構成し、前記外れ止め部材８の揺動アーム１０の下端に接当して該揺動アーム１０の下方側への移動を阻止するための接当部材１２を備え、前記接当部材１２を、前記揺動アーム１０の下方に位置して該揺動アーム１０の下方側への接当位置を上下方向で変更させるためにスライド自在（移動自在）に構成された接当部本体１３と、前記接当部本体１３を複数のスライド位置にて保持するための保持手段１４とから構成している。前記押圧部１１の上面の押圧面（上部レール４の下端と接当する面）１１Ａを円弧形状に構成することによって、上部レール４との接触面積を小さくして、上部レール４との接触抵抗を小さくしているが、他の形状にしてもよい。前記揺動アーム１０の下面に、前記接当部本体１３の先端部上側の角部が引っ掛かって係止保持される鋸歯状になった多数の段部１０Ａを形成して、揺動アーム１０の下方側への接当阻止を係止により確実に行えるようにしているが、段部１０Ａの無いものであってもよい。前記接当部本体１３の先端部１３Ａをこれよりも後方（水平軸芯Ｘから離れる側）に位置する本体部分１３Ｂよりも上面を低くしてあり、図２（ｂ）に示すように揺動アーム１０の水平軸芯Ｘ側へできる限り近づけることができるようにしているが、同一高さにして実施することもできる。図２（ａ）では、支持部材１５の底壁１５Ａの上面に外れ止め部材８の揺動アーム１０の下端が接触する最下降位置を示しているが、網戸５を外せることができる高さであれば、最下降位置でなくてもよい。又、図２（ｂ）では、揺動アーム１０の水平（揺動）軸芯側端部の下面１０Ｂが、支持部材１５の底壁１５Ａの上面に接当して、最大上昇位置（図では水平面に対してほぼ３４度の角度となる位置）になっているが、上框６の上壁部分６Ａの上面と上部レール４の下面との間の隙間（距離）によって調節することになる。しかも、図２（ｂ）の最大揺動角度も変更することもできる。
前記揺動アーム１０及び前記押圧部１１について上述すれば、その揺動アーム１０の遊端（水平軸芯Ｘから離れる端）の上面には、上方に半円状に突出するとともに揺動アーム１０よりも厚みを薄くした前記接当部１０Ｓを形成し、残りの揺動アーム１０の遊端で上端からほぼ三日月状に水平方向でかつ揺動アーム１０の厚み方向に突出する状態で前記押圧部１１を形成することによって、揺動アーム１０の強度を高めながらも、必要となる接当部１０Ｓと押圧部１１とを備えさせることができるようにしているが、接当部１０Ｓと押圧部１１とを別体に構成して、それらを一体化してもよい。 Each of the locking members 8 has a locking position (see FIGS. 1 and 2B) in which the upper end (the upper surface of the contact portion 10S in the drawing) is positioned above the lower end of the upper rail 4. The upper and lower positions of the upper rail 4 are arranged below the lower end of the upper door 4 so that the upper and lower doors can be unlocked (see FIG. 2A). More specifically, as shown in FIGS. 1, 2A, 2B and 3, the anti-slip member 8 is moved around the horizontal axis X by a pin P penetrating a support member 15 described later. A plate-like rocking arm 10 made of a synthetic resin that is rockable up and down and is urged to rock by the helical spring 9 that is an example of an elastic member. The swing arm 10 is integrated with the swinging arm 10 so as to have a top surface positioned below the top surface of the contact portion 10S for retaining to be provided at the free end, and to protrude in the horizontal direction toward the upper rail 4 side. The swing arm of the anti-slip member 8 is formed of a synthetic resin pressing portion 11 which is molded and pressed against the lower end of the upper rail 4 as the swing arm 10 swings upward. 10 to prevent the swinging arm 10 from moving downward. The contact member 12 is slidable so that the contact member 12 is positioned below the swing arm 10 to change the contact position to the lower side of the swing arm 10 in the vertical direction ( The contact portion main body 13 is configured to be movable) and holding means 14 for holding the contact portion main body 13 at a plurality of slide positions. The contact surface with the upper rail 4 is reduced by configuring the pressing surface 11A on the upper surface of the pressing portion 11 (the surface contacting the lower end of the upper rail 4) into an arc shape, thereby reducing the contact area with the upper rail 4. However, other shapes may be used. On the lower surface of the swing arm 10, a plurality of stepped portions 10 A having a sawtooth shape, in which the upper corner portion of the contact portion main body 13 is hooked and held, is formed. Although the contact prevention to the lower side can be reliably performed by the locking, the step portion 10A may be omitted. The front end portion 13A of the contact portion main body 13 has a lower upper surface than the main body portion 13B located behind (the side away from the horizontal axis X) and swings as shown in FIG. 2 (b). Although it can be as close as possible to the horizontal axis X side of the arm 10, it can be carried out at the same height. FIG. 2A shows the lowest position where the lower end of the swing arm 10 of the locking member 8 comes into contact with the upper surface of the bottom wall 15A of the support member 15, but at a height at which the screen door 5 can be removed. If it exists, it does not have to be the lowest position. Further, in FIG. 2B, the lower surface 10B of the horizontal (swinging) axis side end portion of the swinging arm 10 is in contact with the upper surface of the bottom wall 15A of the support member 15, and the maximum ascending position (in the drawing). However, it is adjusted by the gap (distance) between the upper surface of the upper wall portion 6A of the upper collar 6 and the lower surface of the upper rail 4. Moreover, the maximum swing angle in FIG. 2B can also be changed.
If the swing arm 10 and the pressing portion 11 are described above, the swing arm 10 protrudes upward in a semicircular shape on the upper surface of the free end (the end away from the horizontal axis X) of the swing arm 10 and the swing arm 10. The pressing portion is formed in a state where the contact portion 10S having a smaller thickness is formed, and protrudes in the horizontal direction in the crescent shape from the upper end at the free end of the remaining swing arm 10 and in the thickness direction of the swing arm 10. 11 can be provided with the required contact portion 10S and the pressing portion 11 while increasing the strength of the swing arm 10, but the contact portion 10S and the pressing portion 11 are provided. May be configured separately and integrated.

前記外れ止め部材８及び前記接当部材１２を、前記網戸５の上框６に支持される上方が開放されるとともに前記接当部本体１３をスライド可能に保持するための開口縁が形成される合成樹脂製の支持部材１５に取り付け、前記接当部材１２の接当部本体１３の被接当側端に前記支持部材１５から外部に延出されて該接当部本体１３をスライドさせるための押し引き用の操作レバー部１６を一体成形して備えさせている。前記操作レバー部１６を指を引っかけやすいように遊端部が９０度折れ曲がった平面視Ｌ字状に構成しているが、角形や丸形の棒状のものであってもよい。 An upper edge of the stopper member 8 and the contact member 12 supported by the upper arm 6 of the screen door 5 is opened and an opening edge for holding the contact portion main body 13 is formed. Attached to the support member 15 made of synthetic resin, the contact member main body 13 is extended from the support member 15 to the contact side end of the contact member main body 13 of the contact member 12 so as to slide the contact member main body 13. An operation lever portion 16 for pushing and pulling is integrally formed. Although the free end portion is bent 90 degrees so that the operation lever portion 16 can be easily caught by a finger, the operation lever portion 16 may be formed in a square shape or a round rod shape.

前記保持手段１４を、前記接当部本体１３の下面にそれのスライド方向に所定間隔を隔てて複数箇所（図では８箇所の多数箇所であるが、２箇所以上であれば、何カ所設けてもよい）に備えた矩形状の凹部１７と、これら凹部１７に係止して複数のスライド位置で前記接当部材１２を保持するために前記支持部材１５の底壁１５Ａの上面に備えた１個の凸部１８（２個以上設けてもよい）とから構成して、スライド位置を８段階で位置調節することによって、揺動アーム１０の揺動角度を８段階に調節できるようにしているが、２段階以上に調節できるのであれば、何段にしてもよい。このように凹凸部による係止にて複数段階に位置調節する構成にすることによって、調節作業の迅速化を図ることができるが、螺子などを利用して無段階に位置調節できるように構成することもできる。 The holding means 14 is provided at a plurality of locations on the lower surface of the contact portion main body 13 with a predetermined interval in the sliding direction thereof (in the figure, there are a large number of eight locations, but if there are two or more locations, several locations are provided. 1) provided on the upper surface of the bottom wall 15A of the support member 15 to hold the contact member 12 at a plurality of sliding positions by engaging with the recesses 17. It is composed of a plurality of convex portions 18 (two or more may be provided), and the swing angle of the swing arm 10 can be adjusted in eight steps by adjusting the slide position in eight steps. However, as long as it can be adjusted to two or more stages, any number of stages may be used. By adopting a configuration in which the position is adjusted in multiple stages by locking with the uneven portion in this way, the adjustment work can be speeded up, but the position can be adjusted steplessly using a screw or the like. You can also.

前記支持部材１５は、図３に示すように、板状で平面視長方形状の前記底壁１５Ａと、この底壁１５Ａの１つの短辺を除いた３辺から上方に立ち上げた３枚の縦壁１５Ｂ，１５Ｃ，１５Ｄと、前記底壁１５Ａに対して垂直方向に立ち上げられた２枚の縦壁１５Ｂ，１５Ｃのうちの一方の縦壁１５Ｃの上端から水平方向に支持部材１５から離間する側へ延出された水平板部１５Ｅと、この水平板部１５Ｅの上面からの一部から上方に立ち上げられた補強用の縦板部１５Ｆと、この縦板部１５Ｆと水平板部１５Ｅの上面とを３箇所で連結して強度を高めるための３枚のリブ１５Ｇとを備え、図１、図２（ａ），（ｂ）及び図３に示すように、前記網戸５の上框６を構成する水平の上壁部分６Ａから室内側に延出された水平板部６Ｂの長手方向両端部のそれぞれに長方形状の貫通孔６Ｋを形成し（図では１個の貫通孔６Ｋのみを示している）、それら貫通孔６Ｋ，６Ｋに前記支持部材１５を入り込ませて該貫通孔６Ｋ，６Ｋの外周縁に係止保持させるための係止部１９，２０を該支持部材１５の長手方向両端にそれぞれ備えさせている。 As shown in FIG. 3, the support member 15 has a plate-like bottom wall 15A that is rectangular in plan view, and three sheets that rise upward from three sides excluding one short side of the bottom wall 15A. The vertical walls 15B, 15C, 15D and the upper end of one of the two vertical walls 15B, 15C raised in the vertical direction with respect to the bottom wall 15A are separated from the support member 15 in the horizontal direction. A horizontal plate portion 15E extended to the side to be bent, a reinforcing vertical plate portion 15F raised upward from a part from the upper surface of the horizontal plate portion 15E, and the vertical plate portion 15F and the horizontal plate portion 15E. And three ribs 15G for increasing the strength by connecting the upper surface of the screen door 5 as shown in FIG. 1, FIG. 2 (a), FIG. 2 (b) and FIG. Both ends in the longitudinal direction of the horizontal plate portion 6B extending from the horizontal upper wall portion 6A constituting the interior 6 to the indoor side Are formed with rectangular through-holes 6K (only one through-hole 6K is shown in the figure), and the support member 15 is inserted into the through-holes 6K and 6K to form the through-holes 6K and 6K. Locking portions 19 and 20 for locking and holding the outer peripheral edge are provided at both ends of the support member 15 in the longitudinal direction.

前記一方の係止部１９が、上方側に位置する程支持部材１５から遠のく前上がり傾斜姿勢となる前記縦壁１５Ｄの上端面１５ｄと前記水平板部１５Ｅから水平方向に延びる鍔部１５ｅの下面とで構成され、前記他方の係止部２０が、前記鍔部１５ｅと反対側の端部の上端に備えさせた凹部２０Ｃ形成用の上下一対の板部２０Ａ，２０Ｂから構成している。従って、貫通孔６Ｋに上方から支持部材１５を操作レバー部１６側から入り込ませて係止部２０を貫通孔６Ｋの長手方向一端に係止した後、他端側を下方に押し込むことによって他端側の係止部１９を貫通孔６Ｋの長手方向他端に係止して支持部材１５を貫通孔６Ｋに係止保持させることができる。ここでは、水平板部１５Ｅを設けている関係上、支持部材１５を貫通孔６Ｋに上方から入り込ませるようにしているが、水平板部１５Ｅを省略して支持部材１５を貫通孔６Ｋに下方から入り込ませて係止させるようにしてもよい。又、係止により支持部材１５を迅速に上框６に備えさせる場合を示しているが、ビスなどを用いて上框に固定する構成であってもよい。 The upper end surface 15d of the vertical wall 15D and the lower surface of the flange portion 15e extending in the horizontal direction from the horizontal plate portion 15E are positioned so that the one locking portion 19 is located farther away from the support member 15 and is more inclined upward. The other locking portion 20 is composed of a pair of upper and lower plate portions 20A and 20B for forming a recess 20C provided at the upper end of the end opposite to the flange portion 15e. Accordingly, the support member 15 is inserted into the through hole 6K from above from the operation lever portion 16 side, the locking portion 20 is locked to one end in the longitudinal direction of the through hole 6K, and then the other end side is pushed downward. The side locking portion 19 can be locked to the other longitudinal end of the through hole 6K, and the support member 15 can be locked and held in the through hole 6K. Here, since the horizontal plate portion 15E is provided, the support member 15 is inserted into the through hole 6K from above, but the horizontal plate portion 15E is omitted and the support member 15 is inserted into the through hole 6K from below. It may be inserted and locked. Moreover, although the case where the support member 15 is quickly provided in the upper collar 6 by the locking is shown, a configuration in which the support member 15 is fixed to the upper collar using a screw or the like may be used.

前記のように構成された外れ止め装置による外れ止め作用について説明すれば、前記外れ止め装置が装着された網戸５を上部レール４に装着すると、外れ止め部材８の揺動アーム１０が外れ止め作用位置（上方）に揺動付勢されることから、図１及び図２（ｂ）に示すように、押圧部１１が上部レール４に常時接当している状態になる。この状態から、網戸５を開閉するために移動することによって、小さなストロークで僅かに上下方向で移動する網戸５に対して揺動アーム１０がつる巻きバネ９の付勢力に抗して下方側及び上方側へ網戸５の動きに追従して揺動することができる、つまり網戸５が上方へ移動すると揺動アーム１０が下降し、網戸５が下方へ移動すると揺動アーム１０が上昇することができるから、上部レール４の下端に押圧部１１が常に接当しながら、網戸５を移動させることができ、網戸５をスムーズかつ軽快に移動させることができるようになっている。そして、移動時に網戸５が不測に大きく浮き上がった場合には、下方側へ揺動する揺動アーム１０の下端が接当部本体１３に接当することによって、揺動アーム１０の下方側への揺動が阻止され、網戸５が外れてしまうことを阻止することができるようになっている。前記揺動アーム１０に対する接当部本体１３のスライド位置は、上部レール４の下端と網戸５の上框６の上端との隙間の大きさに応じて変更することになるが、実際には、揺動アーム１０の接当部１０Ｓの上面が上部レール４の下端よりも下方へ位置することがないように揺動アーム１０の下方側への揺動を接当阻止するスライド位置に設定することになる。前記網戸５を上部レール４から外したい場合には、前記操作レバー部１６を引っ張り操作してから揺動アーム１０を最下降位置まで下方側へ揺動して上部レール４から網戸５の上端を外すことになる。 Explaining the anti-separation effect of the anti-separation device configured as described above, when the screen door 5 to which the anti-skid device is attached is attached to the upper rail 4, the swing arm 10 of the anti-slip member 8 is anti-separation. Since it is oscillated and biased to the position (upward), the pressing portion 11 is always in contact with the upper rail 4 as shown in FIGS. 1 and 2B. From this state, by moving to open and close the screen door 5, the swing arm 10 against the screen door 5 moving slightly in the vertical direction with a small stroke against the urging force of the helical spring 9 and The swinging arm 10 can swing following the movement of the screen door 5 upward, that is, when the screen door 5 moves upward, the swinging arm 10 is lowered, and when the screen door 5 moves downward, the swinging arm 10 is lifted. Therefore, the screen door 5 can be moved while the pressing portion 11 is always in contact with the lower end of the upper rail 4, and the screen door 5 can be moved smoothly and lightly. When the screen door 5 rises unexpectedly and greatly during movement, the lower end of the swing arm 10 swinging downward contacts the contact portion main body 13 so that the swing arm 10 moves downward. Oscillation is prevented and the screen door 5 can be prevented from coming off. The sliding position of the contact portion main body 13 with respect to the swing arm 10 is changed according to the size of the gap between the lower end of the upper rail 4 and the upper end of the upper arm 6 of the screen door 5, The sliding position that prevents the swinging of the swinging arm 10 from being lowered is set so that the upper surface of the contact portion 10S of the swinging arm 10 is not positioned below the lower end of the upper rail 4. become. When it is desired to remove the screen door 5 from the upper rail 4, after pulling the operation lever portion 16, the swing arm 10 is swung downward to the lowest position and the upper end of the screen door 5 is moved from the upper rail 4. Will be removed.

図４（ａ），（ｂ）に示すように、ガラス障子２，３のガラス２１，２１の厚みが図１に比べて厚くなっているため、ガラス障子２，３の上框に挟持させることができるように、該上框の上下方向中間部に水平方向室内側又は室外側に突出する水平板部２Ａ，３Ａを備えさせることによって、上框をそれの中間部から下端にかけたガラスの収納空間を大きく取るようにしている。このように室外側に水平板部３Ａが大きく突出した状態においても、前記外れ止め部材８が上框６に対して下方側へ大きく突出することがないから、ガラス障子２，３の上框を改造することなく、今まで通りのガラス障子２，３を取り付けることができながらも、外れ止め部材８を確実に取り付けることができるようになっている。尚、図４（ａ）に比べて図４（ｂ）の方が水平板部２Ａ，３Ａが室内側及び室外側に大きく突出した状態を示している。又、図４（ａ），（ｂ）において説明しなかった他の部分は、図１のものと同様であり、同一の符号を付している。 As shown in FIGS. 4 (a) and 4 (b), the thickness of the glass 21 and 21 of the glass shoji 2 and 3 is larger than that of FIG. So that the upper plate is provided with the horizontal plate portions 2A and 3A projecting in the horizontal indoor side or the outdoor side at the middle portion in the vertical direction of the upper plate so that the upper plate is placed from the middle portion thereof to the lower end. I try to take a lot of space. Even in the state where the horizontal plate portion 3A protrudes greatly on the outdoor side in this way, the anti-separation member 8 does not protrude greatly downward with respect to the upper flange 6, so that the upper edge of the glass shoji 2, 3 is The glass stoppers 2 and 3 can be attached without modification, and the stopper member 8 can be securely attached. In addition, compared with Fig.4 (a), the direction of FIG.4 (b) has shown the state which the horizontal plate parts 2A and 3A protruded largely indoors and the outdoor side. The other parts not described in FIGS. 4A and 4B are the same as those in FIG. 1, and are given the same reference numerals.

図１では、押圧部１１と外れ止め用の接当部１０Ｓとを揺動アーム１０に備えさせた構成にしたが、図５に示すように、外れ止め用の接当部１０Ｓを省略して上部レール４の下端に接当する押圧部材２２を上下揺動自在に上框６に備えさせて実施してもよい。
具体的には、網戸５の下框２３に、サッシ枠を構成する下部枠２４の下部レール２５の室内側及び室外側の両側に位置して該網戸の外れ止めを行うための外れ止め部２６，２７をそれの下端が該下部レール２５の上端よりも下方に位置する状態で備え、前記網戸５の移動時に該網戸５の浮き上がりにより前記外れ止め部２６，２７を乗り越えて該網戸５が外れてしまうことがないように前記サッシ枠を構成する上部枠１の上部レール４の下端に接当して該網戸５の浮き上がりを規制するための押圧部材２２を複数（図５では１個のみ示しているが、網戸の移動方向に２個以上設けることになる）備えさせている。前記押圧部材２２を支持する構成は、図２及び図３と同一であるため、図示していない。前記各押圧部材２２を、水平軸芯Ｘ周りで上下揺動自在で、かつ、前記上部レール４の下端に押し付け付勢するために上方側へ揺動付勢し、前記押圧部材２２の下端に接当して該押圧部材２２の下方側への移動を阻止するための接当部材１２（図２（ａ），（ｂ）参照）を備え、前記接当部材１２を、前記押圧部材２２の下方に位置して該押圧部材２２の下方側への接当位置を上下方向で変更させるためにスライド自在に構成した接当部本体１３（図２（ａ），（ｂ）参照）と、前記接当部本体１３を複数のスライド位置にて保持させるための保持手段１４（図２（ａ），（ｂ）参照）とから構成している。前記押圧部材２２の室内側及び室外側の両側に、外れ止め用の板部として、上框６の上壁部分６Ａから室内側へ延びる水平板部６Ｂと、上框６の室内側縦壁部に固定されたＵ字状の枠材の室内側の縦板部７とから構成しているが、それらの形状などの具体的構成は図に示されるものに限定されるものではない。又、前記外れ止め部２６，２７の室外側の外れ止め部２７を水平方向に延びる板部から構成し、室内側の外れ止め部２６を前記下框２３に固定される逆Ｕ字状の枠材の室内側の縦板部から構成しているが、それらの形状などの具体的構成は図に示されるものに限定されるものではない。図５の網戸５の外れ止めの構成を、図１のものに置き換えてもよい。 In FIG. 1, the swinging arm 10 includes the pressing portion 11 and the retaining portion 10 S for preventing detachment, but the retaining portion 10 S for preventing detachment is omitted as illustrated in FIG. 5. A pressing member 22 that comes into contact with the lower end of the upper rail 4 may be provided on the upper collar 6 so as to be swingable up and down.
Specifically, the screen door 5 is provided on the lower arm 23 of the lower frame 24 of the lower frame 24 and is provided on both the indoor side and the outdoor side of the lower rail 25 to prevent the screen door from coming off. , 27 with its lower end positioned below the upper end of the lower rail 25, and when the screen door 5 is moved, the screen door 5 is lifted so that the screen door 5 is disengaged by overcoming the locking portions 26, 27. A plurality of pressing members 22 (only one is shown in FIG. 5) for contacting the lower end of the upper rail 4 of the upper frame 1 constituting the sash frame to restrict the lifting of the screen door 5. However, two or more are provided in the moving direction of the screen door). Since the structure for supporting the pressing member 22 is the same as that shown in FIGS. 2 and 3, it is not shown. Each pressing member 22 can swing up and down around a horizontal axis X and swings and urges upward to press and bias the lower end of the upper rail 4. A contact member 12 (see FIGS. 2A and 2B) for contacting and preventing the downward movement of the pressing member 22 is provided, and the contacting member 12 is connected to the pressing member 22. A contact portion main body 13 (see FIGS. 2A and 2B) configured to be slidable so as to change the contact position on the lower side of the pressing member 22 in the vertical direction; It comprises holding means 14 (see FIGS. 2A and 2B) for holding the contact portion main body 13 at a plurality of slide positions. A horizontal plate portion 6B extending from the upper wall portion 6A of the upper heel 6 to the indoor side as a plate portion for preventing detachment on both the indoor side and the outdoor side of the pressing member 22, and an indoor side vertical wall portion of the upper ridge 6 However, the specific configuration such as the shape thereof is not limited to that shown in the figure. Further, the outside-outside stoppers 27 of the outside-preventing parts 26, 27 are configured by horizontally extending plate parts, and the indoor-side outside-stopping part 26 is fixed to the lower collar 23. Although it comprises a vertical plate portion on the indoor side of the material, the specific configuration such as the shape thereof is not limited to that shown in the figure. 5 may be replaced with that of FIG.

図５に示す網戸５の場合には、下部レール２５に対する網戸５の下框２３の係り代、図５では浅い方の係り代Ｌ（室内側の外れ止め部２６の下端と下部レール２５の上端との距離）よりも網戸５の移動時に浮き上がる距離が小さくなるように網戸５の上方への移動を接当部材１２をスライドさせて押圧部材２２の下方側への移動位置を設定することになる。ここでは、下部網戸５の下框２３の室内側の係り代を室外側の係り代よりも小さくなっているが、これとは逆に設定してもよいし、同じに設定してもよい。
前記網戸５の取り外し方として、例えば押圧部材２２又は外れ止め部材８の下方への移動可能量を図５で示した網戸５と網戸５の下框２３の係り代Ｌよりも大きくした状態になるように接当部材１２をスライドさせて押圧部材２２の下方側への移動位置を設定してから、網戸５を上方に持ち上げ、網戸５の下框２３を下部レール２５から室外側（場合によっては室内側でもよい）へ外すことになる。 In the case of the screen door 5 shown in FIG. 5, the engagement margin of the lower arm 23 of the screen door 5 with respect to the lower rail 25, and in FIG. 5, the shallow engagement margin L (the lower end of the indoor side locking portion 26 and the upper end of the lower rail 25. The sliding member 12 is slid to set the moving position of the pressing member 22 to the lower side so that the distance that rises when the screen door 5 moves is smaller than the distance). . Here, although the engagement margin on the indoor side of the lower lid 23 of the lower screen door 5 is smaller than the engagement margin on the outdoor side, it may be set oppositely or may be set the same.
As a method of removing the screen door 5, for example, the downward movable amount of the pressing member 22 or the detachment prevention member 8 is set to be larger than the engagement allowance L of the screen door 5 and the lower arm 23 of the screen door 5 shown in FIG.
