が知られている。Conventionally, as shown in Japanese Utility Model Application Publication No. 54-72371 (see Figures 1 and 2), this type of door roller has an outer cover a and a roller b rotatably supported in the center thereof.
A guide groove e is provided in the front plate d of the outer cover a in the downward direction of the road, and an insertion support piece f provided at one end of the inner lever C is attached to one side wall of the outer cover a. A slide protrusion i protruding forward from the other end of the inner lever C is inserted into the guide groove e so as to be slidable up and down and protrudes to the outside. A stop protrusion j extends laterally in a hook shape, an adjustment screw k is screwed into the upper wall a' of the outer cover a from the outside, and the lower end of the screw abuts against the other end of the inner lever C to perform the adjustment. A device is known in which the mounting height of the roller b relative to the outer cover a can be adjusted by screwing in and loosening a screw k to move an inner lever C up and down.
しかし、この構造の戸車であると外ケースａに形威した

摺動がスムーズに行なえずその結果内レバーｃの調節ビ
スにとの接触部が歪んだりしてローラｂの上下調節が円
滑に出来なくなってしまう。However, in a door roller having this structure, the guide groove e and the bearing hole formed on the outer case a support the sliding protrusion i and the insertion support piece f formed on the inner lever C, respectively, and the sliding protrusion Since the removal stopper protrusion j is used in the shape of i, the shapes of the outer case a and the inner lever C are very complicated, which makes pressing difficult. Guide groove e of case a or protrusion 1 of inner lever C? If the dimensions of J are different from each other, the protrusion 1v of the inner lever C will not be the same when the guide fee is engaged with the protrusion 1vJ. J gets stuck or protrusion 1? j may not slide up and down along the guide groove e, making it impossible to slide up and down smoothly, and as a result, the contact part of the inner lever c with the adjustment screw becomes distorted, making it difficult to adjust the up and down of the roller b. It won't work smoothly.
そこで、各部材に寸法的余裕を与えると今度は構造上内
レバーＣのガタッキがひどくなって建具をスムーズに開
閉できなくなってしまうとの不具合を発生する。Therefore, if a dimensional allowance is given to each member, the inner lever C becomes structurally unstable, resulting in a problem that the fittings cannot be opened and closed smoothly.
このように、前述した従来の戸車では製作上精度的に非
常に厳しい制限を受けるので加工が面倒であるとの不具
合を有する。As described above, the above-mentioned conventional door roller is subject to very severe limitations in terms of manufacturing accuracy, and has the disadvantage that processing is troublesome.
つまり、内レバーＣと外ケースａとは三箇所で摺動自在
に嵌合して上下動可能に連結しであるから、形状が複雑
であるとともに、三箇所の嵌合部の寸法が互にばらつく
と円滑に上下動できないから寸法精度が非常に厳しくな
って加工及び組立が面倒となってしまう。In other words, the inner lever C and the outer case a are slidably fitted at three points and connected to be movable up and down, so the shape is complicated and the dimensions of the three fitting portions are different from each other. If there is variation, it will not be possible to move up and down smoothly, making dimensional accuracy extremely difficult and making processing and assembly troublesome.
本考案は上記の事情に鑑みなされたものであり、その目
的はローラの取付高さを調節できると共に、加工及び組
立が容易なる戸車を提供することである。The present invention was developed in view of the above circumstances, and its purpose is to provide a door roller that allows adjustment of the mounting height of the roller and is easy to process and assemble.
以下第３図以後を参照して本考案の実施例を説明する。Embodiments of the present invention will be described below with reference to FIG. 3 and subsequent figures.
第３図は本考案に係る戸車Ａを網戸Ｂの下框Ｃに取付け

りも下方に延設してガイド片２０を形威している。The inner frame 3 is a box-shaped body with an open bottom formed by an upper wall 12, a vertical wall 13, and side walls 14, 14, and a roller 4 is rotatably supported on the vertical wall 13 via a roller pin 15. A projecting piece 16 is integrally formed on one side wall 14 and is fitted into the engaging portion 11 so as to be slidable up and down, and a mounting piece 17 is integrally formed on the other side wall 14'. The mounting hole 19 through which the pivot pin 18 that is fitted into the support hole 9 is inserted gives shape, and the lower end of the vertical wall 13 extends below both side walls 14 to provide the guide piece 20 with shape. are doing.
前記外枠２の横壁７の端面７ａには一対の切欠２１．２
１が形成され、該切欠２１，２１の中間部には前記調節
ビス５が螺合するビス孔２２が形威しである。A pair of notches 21.2 are provided on the end surface 7a of the horizontal wall 7 of the outer frame 2.
1 is formed, and a screw hole 22 into which the adjustment screw 5 is screwed is formed in the intermediate portion of the notches 21, 21.

のプレート２５．２５の一側隅部を連結材２６．２６で
上下離隔して一体的に連結した形状であり、該ネジロッ
ク２３は前記横壁７に嵌合装着される。Reference numeral 23 denotes a screw lock, which has a shape in which one side corner of a pair of upper and lower plates 25.25 having screw holes 24 are integrally connected to each other by a connecting member 26.26 with vertical separation apart. It is fitted and installed.
この時一対の連結材２６．２６が一対の切欠２１，２１
に嵌合してそのビス孔２４゜２４とビス孔２２とが合致
するように位置決めされる。At this time, the pair of connecting members 26, 26 are connected to the pair of notches 21, 21.
The screw hole 24 is positioned so that the screw hole 24 matches the screw hole 22.
しかして、内枠３は枢軸ピン１８で外枠２に上下揺動自
在に装着支持され、突片１６が係合部１１に挿入され、
該係合部１１に沿って上下動可能なるストローク（第７
図Ｘ）だけ内枠３は外枠２に対して上下揺動する。Thus, the inner frame 3 is attached to and supported by the outer frame 2 with the pivot pin 18 so as to be able to swing vertically, and the protruding piece 16 is inserted into the engaging portion 11.
A stroke (seventh stroke) that allows vertical movement along the engaging portion 11
The inner frame 3 swings up and down relative to the outer frame 2 by the amount shown in FIG.
また、調節ビス５はネジロック２３、ビス孔２２に螺合
して内枠３の上壁１２に当接し、調節ビス５をネジ込む
ことによって内枠３は枢軸ピン１８を中心として下方に
揺動するので、ローラ４の取付高さを調節できる。In addition, the adjustment screw 5 is screwed into the screw lock 23 and the screw hole 22 and comes into contact with the upper wall 12 of the inner frame 3, and by screwing the adjustment screw 5, the inner frame 3 swings downward about the pivot pin 18. Therefore, the installation height of the roller 4 can be adjusted.
また、内枠３の一端は外枠２に枢軸ピン１８で上下揺動
自在に枢着され、他端に形成された前記突片１６は前記
保合部１１に上下動自在に嵌挿しであるから、加工誤差
等によって係合部１１と突片１６との嵌挿位置が多少異
なっても内枠３はスムーズに外枠２に対して上下揺動で
きる。Further, one end of the inner frame 3 is pivotally attached to the outer frame 2 by a pivot pin 18 so as to be able to freely swing up and down, and the protruding piece 16 formed at the other end is fitted into the retaining portion 11 so as to be able to move up and down. Therefore, even if the fitting positions of the engaging portion 11 and the projection piece 16 are slightly different due to machining errors or the like, the inner frame 3 can smoothly swing up and down with respect to the outer frame 2.
したがって、寸法精度が多少粗くても良いので加工及び
組立が容易となる。Therefore, since the dimensional accuracy may be somewhat rough, processing and assembly are facilitated.
また、外枠２の係合部１１は縦壁６の一部分１０を打出
して形成しであるから係合部１１を容易に形成できるか
ら外枠２を容易に製作できる。Further, since the engaging portion 11 of the outer frame 2 is formed by punching out a portion 10 of the vertical wall 6, the engaging portion 11 can be easily formed, and the outer frame 2 can be manufactured easily.
また、内枠１３はガイド片２０が一体形成され、該ガイ
ド片２０は網戸レール２７の室内側に突出しているから
網戸Ｂが網戸レール２７から外れることを防止できる。Further, the inner frame 13 is integrally formed with a guide piece 20, and the guide piece 20 protrudes toward the indoor side of the screen door rail 27, so that the screen door B can be prevented from coming off from the screen door rail 27.
なお、外枠２は網戸下框Ｃの内面に設けた裏板２８にビ
ス１を螺合して締付固着しである。The outer frame 2 is secured by screws 1 screwed onto a back plate 28 provided on the inner surface of the lower stile C of the screen door.
