しかし、特許文献１では、操作部は退避位置にあるときに竪框の下端において室内側壁と室外側壁との間に位置するので、竪框の室外側壁の下端コーナが露出しており、このコーナで怪我をさせる可能性があり、コーナを塞ぐ部品（端部キャップ）が必要になるので、網戸の製造コストが高くなると共に網戸の組立て性に劣るという問題がある。 However, in Patent Document 1, since the operating portion is located between the indoor side wall and the outdoor side wall at the lower end of the heel when in the retracted position, the lower end corner of the outdoor side wall of the heel is exposed. Injuries may occur, and parts (end caps) for closing the corners are required, which raises the problem that the manufacturing cost of the screen door becomes high and the screen door is not easily assembled.

そこで、本発明は、使用者の安全性を高めると共に網戸の製造コストを低くでき且つ網戸の組立て性が良い網戸用戸車の提供を目的とする。 Then, this invention aims at provision of the door door for screen doors which can raise a user's safety, can lower the manufacturing cost of a screen door, and has good assembly property of a screen door.

請求項１に記載の発明は、ケースと、スライダーと、車輪保持具と、車輪の上下位置調整具とを備え、ケースは網戸の下框と竪框のコーナ部に取付けるものであり、スライダーは、下框の長手方向に移動自在にケースに取付けてあると共に網戸先端側に操作部を有し、操作部は竪框の室外側壁の下端コーナに設けた切除部に位置して竪框の室外側面と略連続する退避位置と網戸先端から突出する突出位置に移動自在なものであり、車輪保持具は、スライダーに連動して移動自在にケースに設けたものであり、操作部が退避位置にあるときに車輪が下方移動できる位置にあると共に、操作部が突出位置にあるときに車輪の下方移動が規制される位置にあり、上下位置調整具は車輪が下方向移動できる位置にある車輪保持具に上方から当接して車輪が上方へ移動するのを規制することを特徴とする。 The invention described in claim 1 includes a case, a slider, a wheel holder, and a wheel vertical position adjuster, and the case is attached to a corner of the screen door and the saddle, , Which is attached to the case so as to be movable in the longitudinal direction of the lower heel and has an operation portion at the end of the screen door, and the operation portion is located at the cut-out portion provided at the lower end corner of the outer wall of the heel. The wheel holder is provided in the case so that it can be moved in conjunction with the slider. The wheel is in a position where the wheel can move downward at a certain time, and is in a position where the downward movement of the wheel is restricted when the operating portion is in the protruding position, and the vertical position adjuster is a wheel holding position where the wheel can move downward. A car that touches the tool from above There characterized by restraining the upward movement.

請求項１に記載の発明によれば、網戸の建込み時には、操作部が竪框から網戸先端側に突出する位置にあるときには、車輪保持具は車輪の下方移動を規制する位置にあり、車輪が網戸の建込みの邪魔にならず、建込みが容易にできる。
網戸を建込んだ後、操作部が移動して退避位置にあるときには、車輪保持具に上下位置調整具が当接して車輪が上に移動するのが規制されると共に車輪保持具が下方移動できる位置にあるので、網戸を建込んだ状態で網戸が持ち上げられると、車輪保持具が下方に移動自在であるから車輪はレールからの外れが防止される。
網戸を取外すときは、建込み時と同様に操作部が竪框から網戸先端側に突出する位置へ移動すると、スライダーに連動して車輪保持具は車輪の下方移動が規制される位置に移動し、車輪がケースに対して下がらないように規制するので、この状態で網戸を持ち上げても、車輪が邪魔にならずに網戸外しができる。
操作部が退避位置にあるとき、操作部は竪框の室外側面に略連続して位置して、切除部を塞いでいるので、切除部による怪我防止の為に切除部に別途塞ぎ部材（端部キャップ）を設けなくて済み、網戸の製造コストを低くでき且つ組立て性が良い。 According to the first aspect of the present invention, when the screen door is installed, the wheel holder is in a position for restricting the downward movement of the wheel when the operation portion is in a position protruding from the bag toward the screen door tip side. However, it does not get in the way of installing the screen door and can be installed easily.
After the screen door is built, when the operation unit moves and is in the retracted position, the vertical position adjuster comes into contact with the wheel holder to restrict the wheel from moving upward and the wheel holder can move downward. Since it is in the position, when the screen door is lifted in a state where the screen door is installed, the wheel holder is movable downward, so that the wheel is prevented from coming off the rail.
When removing the screen door, if the operating part moves from the saddle to a position where it projects to the tip of the screen door in the same way as when erected, the wheel retainer moves to a position where the downward movement of the wheel is restricted in conjunction with the slider. Since the wheel is regulated so as not to be lowered with respect to the case, even if the screen door is lifted in this state, the screen door can be removed without the wheel getting in the way.
When the operating part is in the retracted position, the operating part is positioned substantially continuously on the outer side surface of the heel and closes the excision part. Therefore, in order to prevent injury by the excision part, a separate blocking member (end No part cap) is required, and the manufacturing cost of the screen door can be reduced and the assemblability is good.

次に、第１実施の形態にかかる網戸用戸車１の取付け、網戸の組立て、作用及び効果について説明する。
網戸用戸車１を網戸５の下框７に装着するときには、操作部３２をケース１３から突出する方向に引き出すように操作してスライド操作部３５を網戸幅方向の先端側に位置させることにより、ガイド溝２５の下縁２７は車輪１９が下がらないように車輪保持具１７を規制した状態にしておく。この状態で、網戸用戸車１を網戸５の下框７に下から押し込んで、下框７の内部に固定する。
網戸５の組立てにおいて、下框７と竪框８との組み付けは、図５に示すように、網戸用戸車１を装着した下框７を竪框８の下端の内部に押し込む。これにより、竪框８の係合部８ｃに下框７の被係合部７ｃが係合してほぞ組みにより取付けられると共に、網戸用戸車１に設けてある係止部３０が竪框８の被係止孔３４に係止する。したがって、下框７と竪框８との組み付けは、下框７を竪框８の下端から押し込むだけで容易に組み付けできる。
網戸５の建込み時には、図１（ａ）に示すように、下框７の室内側面に設けてあるスライド操作部３５を、下框７の長孔３７の先端３７ａ側に位置させる。
これにより、スライダー１５がケース１３に対して網戸幅方向の先端側に位置するので、車輪保持具１７に設けてあるガイド軸７１はガイド溝２５の網戸幅方向先端側に位置し、ガイド溝下縁２７の網戸幅方向先端２７ａは車輪１９が下がらないように、車輪保持具１７の下方への回動を規制する。したがって、スプリング２１により車輪保持具１７の網戸幅方向中央部側を常時下方に付勢されていても車輪保持具１７のガイド軸７１をガイド溝下縁２７の網戸幅方向先端２７ａが規制して、車輪１９を上位置で保持する。即ち、外れ止めが解除されるので、網戸の建込み時に車輪１９がケース１３から下がることがなく、車輪１９が邪魔にならずに建込みができ、建込み作業が容易にできる。
網戸５を建込んだ後には、図１（ｂ）に示すように、スライド操作部３５を長孔３７の網戸幅方向中央部３７ｂに移動する。これにより、車輪保持具１７がスライダー１５と共に網戸幅方向中央部側に移動するので、車輪保持具１７のガイド軸７１がガイド溝２５の網戸幅方向中央部側に位置して、ガイド溝２５の湾曲に沿って下方に移動自在になると共に、車輪保持具１７の網戸幅方向中央部側上縁１７ａに高さ規制部材７５の下端７５ｂが当接して車輪１９が上方に移動するのを規制するので、車輪１９が予め調整した所定の高さ（上下位置）に保持される。
車輪１９の高さ（上下位置）調整は、上下位置調整具２４において、下框７の室内側壁に設けてある開口部７９から突設したねじ７７の頭７７ａをドライバで緩め、高さ調整部材７３を網戸幅方向にスライドする。これにより、高さ調整部材７３の傾斜面８３に当接する高さ規制部材７５が傾斜面８３に沿って上方又は下方に移動するので、網戸５を建て込んだまま且つ下框７の室内側から車輪１９の高さを調整することができる。車輪１９の高さ調整後はねじ７７を締め付けて高さ調整部材７３をその位置で固定する。
図２に示すように、網戸５を建込んだ状態（図１（ｂ））で網戸５が矢印Ｓで示すように持ち上げられると、スプリング２１が車輪保持具１７の網戸幅方向中央部側を下方に向けて常時付勢しているので、車輪保持具１７が水平軸３１を中心として下方に向けて回動し、ガイド軸７１はガイド溝２５の中央部側下縁２７ｂの湾曲に沿って移動するので、車輪１９は、図１（ｂ）に示す位置から図２に示すようにケース１３に対して相対的に下方に移動して、レール１１との係合が保持される。
一方、網戸のメンテナンス等の為に、網戸５を外すときには、建込み時（図１（ａ））と同様に、下框７の室内側面に設けてあるスライド操作部３５を長孔３７の網戸幅方向先端３７ａ側に移動することにより、車輪保持具１７のガイド軸７１はガイド溝２５の網戸幅方向先端側に移動し、下縁２７の網戸幅方向先端２７ａで車輪保持具１７の下方への移動を規制する。この状態で網戸５を持ち上げても車輪１９が下がらず、車輪１９が邪魔にならずに網戸外しが容易にできる。 Next, the installation of the screen door door pulley 1 according to the first embodiment, the assembly of the screen door, the operation and the effect will be described.
When the screen door cart 1 is mounted on the lower arm 7 of the screen door 5, by operating the operation unit 32 to be pulled out from the case 13 and positioning the slide operation unit 35 on the front end side in the screen door width direction, The lower edge 27 of the guide groove 25 keeps the wheel holder 17 restricted so that the wheel 19 is not lowered. In this state, the screen door door pulley 1 is pushed into the lower arm 7 of the screen door 5 from below, and fixed inside the lower arm 7.
In assembling the screen door 5, the lower heel 7 and the heel 8 are assembled by pushing the lower heel 7 on which the screen door door cart 1 is mounted into the lower end of the heel 8 as shown in FIG. 5. As a result, the engaged portion 7c of the lower rod 7 is engaged with the engaging portion 8c of the rod 8 and attached by a tenon assembly, and the locking portion 30 provided on the screen door door pulley 1 is Locks in the locked hole 34. Therefore, the lower rod 7 and the rod 8 can be easily assembled by simply pushing the lower rod 7 from the lower end of the rod 8.
When the screen door 5 is installed, as shown in FIG. 1A, the slide operation part 35 provided on the indoor side surface of the lower heel 7 is positioned on the tip 37 a side of the long hole 37 of the lower heel 7.
As a result, the slider 15 is positioned on the front end side in the screen width direction with respect to the case 13, so the guide shaft 71 provided on the wheel holder 17 is positioned on the front end side in the screen door width direction of the guide groove 25, and below the guide groove. The screen door width direction front end 27a of the edge 27 restricts the downward rotation of the wheel holder 17 so that the wheel 19 is not lowered. Therefore, even if the central portion of the wheel holder 17 in the width direction of the door 17 is always biased downward by the spring 21, the guide shaft 71 of the wheel holder 17 is regulated by the tip 27a of the guide groove lower edge 27 in the door width direction. The wheel 19 is held in the upper position. That is, since the detachment prevention is released, the wheel 19 does not fall from the case 13 when the screen door is installed, the wheel 19 can be installed without obstruction, and the installation work can be facilitated.

Thereby, since the wheel holder 17 moves to the screen door width direction center part side with the slider 15, the guide axis | shaft 71 of the wheel holder 17 is located in the screen door width direction center part side of the guide groove 25, and the guide groove 25 of FIG. The lower end 75b of the height regulating member 75 comes into contact with the upper edge 17a on the center side in the width direction of the screen door of the wheel holder 17, and the movement of the wheel 19 is restricted. Therefore, the wheel 19 is held at a predetermined height (vertical position) adjusted in advance.
The height (vertical position) of the wheel 19 is adjusted by loosening the head 77a of the screw 77 projecting from the opening 79 provided in the indoor side wall of the lower rod 7 with a screwdriver in the vertical position adjusting tool 24. 73 is slid in the screen door width direction. As a result, the height regulating member 75 that contacts the inclined surface 83 of the height adjusting member 73 moves upward or downward along the inclined surface 83, so that the screen door 5 is still built and the indoor side of the lower lid 7 is The height of the wheel 19 can be adjusted. After adjusting the height of the wheel 19, the screw 77 is tightened to fix the height adjusting member 73 at that position.
As shown in FIG. 2, when the screen door 5 is lifted as shown by the arrow S in the state where the screen door 5 is installed (FIG. 1B), the spring 21 moves the screen door width direction center portion side of the wheel holder 17. Since the wheel holder 17 is constantly biased downward, the wheel holder 17 rotates downward about the horizontal shaft 31, and the guide shaft 71 follows the curvature of the lower edge 27 b on the center portion side of the guide groove 25. Since the wheel 19 moves, the wheel 19 moves downward relative to the case 13 as shown in FIG. 2 from the position shown in FIG. 1B, and the engagement with the rail 11 is maintained.
On the other hand, when the screen door 5 is removed for maintenance of the screen door or the like, the sliding operation portion 35 provided on the indoor side surface of the lower arm 7 is replaced with the screen door of the long hole 37 in the same manner as when the screen door 5 is installed (FIG. 1A). By moving to the width direction front end 37 a side, the guide shaft 71 of the wheel holder 17 moves to the screen door width direction front end side of the guide groove 25, and below the wheel holder 17 at the screen door width direction front end 27 a of the lower edge 27. Regulate the movement of Even if the screen door 5 is lifted in this state, the wheel 19 does not drop, and the screen door can be easily removed without the wheel 19 getting in the way.
