Description

【０００１】
【産業上の利用分野】
本発明は、上吊り式サッシに用いる吊車の障子框に対する高さ（障子框に対する吊車の突出量）、すなわち、上枠に対する障子框の離開幅の調節装置に関するものである。
【０００２】
【従来の技術】
例えば、実公昭５４−２８３７７号公報所載の通り、吊車本体の取付け杆に小径部を段設し、任意の小径部を障子框に設けた挾持板で挾持し、該挾持状態を前記挾持板を挾持方向に付勢するばねで維持するようにした構造のものがある。
【０００３】
【発明が解決しようとする課題】
前記従来例は、取付け杆に段階的にして吊車の高さ調節を行うものであるから段階的な高さ調節しか行えず、いわゆる微調節を行えない構造となっている。
【０００４】
本発明は、従来例の斯様な欠点を回避し、斬新な構造の調節装置を提供するものである。
【０００５】
【課題を解決するための手段】
上枠に設けた案内レール上に載置したローラと該ローラを回動自在に枢着した吊車本体とからなる吊車の前記吊車本体に縦長の長孔を設け、該長孔を通じて締付け螺子の先端を障子框に設けた螺子孔に螺合して前記吊車本体を前記障子框に組付けると共に、前記吊車本体に前記長孔と縦方向に並べて窓口を形成し、該窓口の周縁に圧接して前記吊車本体を下方に押圧するカム片を、前記障子框に外部から回動操作可能に組付けた構成としたものである。
【０００６】
【作用】
外部からカム片を回動操作すると、カム片は吊車本体に形成した窓口の周縁に圧接して吊車本体を下方に押圧し、吊車本体（吊車）は上枠の案内レール上にローラを載置して高さ方向において定位置を維持しているため、前記の押圧作用は、締付け螺子を緩めて吊車に対して自由状態にある障子框に負荷され、締付け螺子の長孔との係合関係により、負荷の方向によって障子框は吊車本体に沿って上昇或いは降下し、障子框の高さ調節（障子框に対する吊車の相対的な突出量の調節）が行われ、該調節状態は、締付け螺子を締め付けることによって維持される。
【０００７】
【実施例】
図面は本発明に係る吊車の高さ位置調節装置の一実施例を示し、図１は本発明要部の一部欠截正面図、図２は図１の側面図、図３は図１の横断面図、図４は配置関係を示す略示正面図である。
【０００８】
実施例のものは、互いに回転自在に接続した一対の障子１，１´で成る一対の折たたみサッシ構成体Ａ，Ａを窓枠２に組付けて折たたみサッシを構成し、該折たたみサッシの折たたみサッシ構成体Ａの召合せ側の障子１の縦框１ａに蝶番を介して操作框３を接続し、該操作框３に、前記窓枠２の上枠２ａに設けた案内レール４上を転動するローラ５を備えた吊車６を組付け、この吊車６の前記操作框３に対する突出量（上枠２ａに対する操作框３上端の離開幅）調節のために本発明装置を適用したものであるが、本発明装置は実施例のような構造以外のサッシに適用できることは勿論である。
【０００９】
前記操作框３の前記縦框１ａに対向する外側の部片３ａには、該部片３ａの内側に重ね合わせて裏板７をビス１９で止着し、この裏板７の前記部片３ａの窓孔８に嵌合した膨出部７ａにカム９の偏心軸９ｂを回動可能に組付け、カム片９ａを前記部片３ａ表面に突出させて、前記吊車６の取付け片１０に設けた窓口１１に回動可能に係合してある。
【００１０】
吊車６は、主体ブロック１２と該主体ブロック１２の一端に縦長の前記取付け片１０を連設して成る吊車本体１３の主体ブロック１２の両端に一対の前記ローラ５，５を回動自在に枢着して構成し、前記取付け片１０に前記窓口１１と該窓口１１を介する上下に縦長長孔１４，１４を設け、該縦長長孔１４を通じて締付け螺子１５を前記部片３ａ乃至裏板７に形成した螺子孔１６に螺合して締付け、窓口１１に、前記の通り、カム片９を回動可能に係合して操作框３に組付け、ローラ５を前記案内レール４上に転動自在に載置したものである。
【００１１】
前記カム９は、円形板状のカム片９ａと該カム片９ａの一側に偏位させて突設した偏心軸９ｂとで成り、カム片９ａの、偏心軸９ｂの延長上の表面には工具（ドライバー）の係止溝１７を設けて構成し、円形のカム片９ａの径と横長方形状の前記窓口１１の高さ幅をほぼ同じくして、前記の通り、カム片９ａを窓口１１に回動可能に係合したものである。
【００１２】
しかして、図２の状態において、締付け螺子１５を緩めて、カム片９ａを係止溝１７を利用して回動させると、カム片９ａは偏心軸９ｂに対して偏心して回動して、窓口１１の縁部に圧接し、当該縁部部分を介して本体１３を下方に押圧し、このとき吊車６の本体１３の高さ方向の位置の変動が生じないから、操作框３は、締付け螺子１５の縦長長孔１４に沿う上昇に案内されるように（すなわち、垂直方向）上昇し、例えば、図２の２点鎖線位置にまで上昇し、この状態で締付け螺子１５を締め付けることにより、当該上昇した状態が維持される。
【００１３】
また、修理乃至点検時には締付け螺子１５を取り外すことにより吊車本体１３と操作框３乃至障子１を互いに離脱することができる。
【００１４】
【発明の効果】
本発明は前記の通りの構成であるから、無段階に吊車の高さ位置調節（障子框に対する吊車の突出量調節乃至上枠に対する障子框の離開幅調節）を簡単に行うことができ、従って、微調節を行え、また、締付け螺子を取り外すことにより吊車と障子框を互いに分離できるから、保守点検作業上好適である。

[Industrial application fields]
The present invention relates to a device for adjusting the height of a suspension car used for an upper suspension sash (the amount of protrusion of the suspension car relative to the shoji fence), that is, an opening width of the shoji fence relative to an upper frame.
[0002]
[Prior art]
For example, as disclosed in Japanese Utility Model Publication No. 54-28377, a small-diameter portion is stepped on a mounting rod of a suspension vehicle body, and an arbitrary small-diameter portion is held by a holding plate provided on a shoji rod, and the holding state is indicated by the holding plate. There is a structure that is maintained by a spring that biases in the holding direction.
[0003]
[Problems to be solved by the invention]
In the conventional example, the height of the suspension wheel is adjusted step by step on the mounting rod, so that only a stepwise height adjustment can be performed, and so-called fine adjustment cannot be performed.
[0004]
The present invention avoids such drawbacks of the conventional example and provides an adjustment device having a novel structure.
[0005]
[Means for Solving the Problems]
A vertically long slot is provided in the suspension vehicle body of a suspension vehicle composed of a roller mounted on a guide rail provided on the upper frame and a suspension vehicle body pivotally mounted on the roller, and a tip of a fastening screw is passed through the elongated hole. The suspension car body is assembled to the shoji fence by screwing it into a screw hole provided in the shoji guard, and a window is formed in the suspension car body in the longitudinal direction with the long hole, and is pressed against the periphery of the window. The cam piece that presses the suspension vehicle body downward is assembled to the shoji cage so as to be rotatable from the outside.
[0006]
[Action]
When the cam piece is rotated from the outside, the cam piece is pressed against the peripheral edge of the window formed on the suspension car body to press the suspension car body downward, and the suspension car body (suspension car) places a roller on the guide rail of the upper frame. Thus, since the fixed position is maintained in the height direction, the pressing action is applied to the shoji cage in the free state with respect to the suspension wheel by loosening the fastening screw, and the engagement relationship with the elongated hole of the fastening screw. Thus, the shoji cage is raised or lowered along the suspension car body depending on the direction of the load, and the height of the shoji fence is adjusted (adjustment of the relative protruding amount of the suspension car with respect to the shoji fence). Maintained by tightening.
[0007]
【Example】
The drawings show an embodiment of the height position adjusting device for a suspension vehicle according to the present invention, FIG. 1 is a partially cutaway front view of the main part of the present invention, FIG. 2 is a side view of FIG. FIG. 4 is a schematic front view showing the arrangement relationship.
[0008]
In the embodiment, a pair of folding sash members A, A each composed of a pair of shojis 1, 1 'connected to each other are assembled to the window frame 2 to form a folding sash, and the folding sash is formed. An operating rod 3 is connected to the vertical rod 1a of the shoji 1 on the summing side of the folding sash structure A through a hinge, and the guide rail 4 provided on the upper frame 2a of the window frame 2 is connected to the operating rod 3. A suspension wheel 6 provided with a roller 5 that rolls up is assembled, and the device of the present invention is applied to adjust the protruding amount of the suspension wheel 6 with respect to the operation rod 3 (the separation width of the upper end of the operation rod 3 with respect to the upper frame 2a). However, it goes without saying that the device of the present invention can be applied to sashes other than the structure as in the embodiment.
[0009]
On the outer piece 3a of the operation rod 3 facing the vertical rod 1a, a back plate 7 is fastened with screws 19 so as to overlap the inside of the piece 3a, and the piece 3a of the back plate 7 is fixed. The eccentric shaft 9b of the cam 9 is rotatably attached to the bulging portion 7a fitted in the window hole 8, and the cam piece 9a is projected on the surface of the piece 3a so as to be provided on the mounting piece 10 of the suspension wheel 6. It is engaged with the window 11 so as to be rotatable.
[0010]
The suspension vehicle 6 pivotally pivots a pair of rollers 5 and 5 at both ends of a main block 12 of a main suspension block 13 formed by connecting a main block 12 and a vertically long mounting piece 10 to one end of the main block 12. The installation piece 10 is provided with the window 11 and vertically long holes 14, 14 above and below the window 11, and a fastening screw 15 is attached to the piece 3 a to the back plate 7 through the vertically long hole 14. Screwed into the formed screw hole 16 and tightened. As described above, the cam piece 9 is rotatably engaged with the window 11 and assembled to the operating rod 3, and the roller 5 rolls on the guide rail 4. It is placed freely.
[0011]
The cam 9 is composed of a circular plate-like cam piece 9a and an eccentric shaft 9b that is offset from one side of the cam piece 9a. The cam piece 9a has a surface on the extension of the eccentric shaft 9b. A locking groove 17 for a tool (driver) is provided, the diameter of the circular cam piece 9a is substantially the same as the height of the horizontal rectangular window 11, and the cam piece 9a is connected to the window 11 as described above. It is engaged so that it can rotate.
[0012]
In the state of FIG. 2, when the fastening screw 15 is loosened and the cam piece 9a is rotated using the locking groove 17, the cam piece 9a rotates eccentrically with respect to the eccentric shaft 9b. The body 13 is pressed against the edge of the window 11 and pressed downwardly through the edge, and the position of the suspension 13 in the height direction of the body 13 does not change. The screw 15 is lifted so as to be guided along the vertically elongated hole 14 (that is, in the vertical direction), for example, lifted to the position of the two-dot chain line in FIG. 2, and in this state, by tightening the tightening screw 15, The elevated state is maintained.
[0013]
Moreover, the suspension main body 13 and the operating rod 3 through the shoji 1 can be separated from each other by removing the fastening screw 15 at the time of repair or inspection.
[0014]
【The invention's effect】
Since the present invention is configured as described above, the height position adjustment of the suspended vehicle (adjustment of the protruding amount of the suspended vehicle with respect to the shoji cage or adjustment of the separation width of the shoji cage with respect to the upper frame) can be easily performed steplessly. Fine adjustment can be performed, and the suspension wheel and the shoji fence can be separated from each other by removing the tightening screw, which is preferable for maintenance and inspection work.
