【発明の属する技術分野】
本発明は、鉄道車両の扉などに設けられて昇降する窓のバランサー装置に関する。
【0002】
【従来の技術】
従来、鉄道車両の扉、例えば運転室や車掌室の出入口の扉に設けられる落とし窓は、人力で上下して開閉される。そのため、このような落とし窓の開閉は軽く操作できなければならないことから、通常、落とし窓の重量を軽減するためのバランサーが付設されている。
【0003】
このような落とし窓のバランサーについては、複数のリンク部材や複数のスプリング等により構成したもの(例えば特許文献1参照)や、揺動アーム、連結アーム、エアシリンダ等で構成したもの(例えば特許文献2参照)や、複数のリンクやアクチュエータ等で構成したもの(例えば特許文献3参照)や、複数のリンクやレバー等で構成したもの(例えば特許文献4参照)が知られている。

【発明を解決しようとする課題】
ところで、前記のようなバランサーは、特に人力操作のものにおいては、落とし窓がわずかな力で動き、所望の位置で停止することが望まれるため、微妙な付加力の調整が必要となる。
【0006】
しかし、前記従来のバランサーの構造は複雑である上に、人力操作のものでは、バネやアクチュエータの付加力の調整は困難である。
【0007】
そこで本発明は、昇降する窓を人力等で軽く操作でき、所望の位置で容易に停止でき、かつ、バランサーの構造を簡単にし、付加力の調整も簡単に行える窓のバランサー装置を提供することを目的とするものである。
【0008】
【課題を解決するための手段】
前記の課題を解決するために、請求項1記載の発明は、枠内に窓を昇降可能に設け、該窓の下部に腕を配置して該腕の上端で前記窓の下部を支承し、腕の下端を前記枠の一方の側枠に回転可能に連結し、前記腕よりも下方位置の前記一方の側枠には支持部材を固設し、前記腕の下部に位置して複数個の上部軸穴を腕の長手方向に適宜間隔を有して形成し、前記支持部材には下辺水平方向の波形面に形成し、上辺を水平方向の直線面で形成した長穴状の下部軸穴を水平方向に形成し、前記腕と支持部材間に、腕を上方へ付勢する付勢手段を、その上端を前記上部軸穴に係合し、下端を前記下部軸穴の波形面に係合して架設したことを特徴とする窓のバランサー装置である。
【0009】
本発明においては、付勢手段の上端を、腕に形成した複数個の上部軸穴に選定して係合することにより、窓の下降力に対する腕の反発力を調整することができる。
【0010】
また、付勢手段の下端を、下部軸穴に沿って移動させ所望位置の波形面に係止することにより、窓の下降力に対する腕の反発力を調整することができる。
【0011】
この調整時において、前記上部軸穴の間隔を広くし、この間隔よりも前記波形面の間隔を狭く設定することにより、上部軸穴で大きな調整をし、波形面で微調整を行うことができる。
【0012】
請求項2記載の発明は、前記請求項1記載の発明において、前記付勢手段をガススプリングで形成したものである。
【0013】
【発明の実施の形態】
本発明の好ましい実施の形態を図に示す実施例に基づいて説明する。
【0014】
図の実施例は、本発明を鉄道車両における扉、例えば運転室や車掌室の出入口の扉における落とし窓に適用した例を示すが、本発明はこのような扉の落とし窓に限るものではなく、その他の昇降窓に適用できるものである。
【0015】
図1乃至図8に示す第1実施例において1は扉を示し、該扉1の側枠1aには、対向して2本のレール2,3が垂直方向に配置され、該両レール2,3間に落とし窓4が昇降可能に嵌合されている。該落とし窓4の下面にはコロ案内部材5が水平方向に備えられており、該コロ案内部材5にコロ6が回転可能に嵌合され、コロ6がコロ案内部材5に沿って水平方向に移動するようになっている。
【0016】
前記コロ6には、コロ軸7により腕8の上端が回転可能に連結され、該腕8の下端が扉1の一方の側枠1aに固設した腕軸取付金9に、腕軸10によって回転可能に連結されている。そして、前記腕8は、腕軸10を中心として、図2の実線の如く傾斜した上昇状態Aから、鎖線の如く傾斜した下降状態B間において揺動するようになっている。なお、水平状態をCで示す。
【0017】
前記腕8には上部軸穴11が形成されており、図の実施例では、腕8の下部において、腕8の長手方向に沿って複数、例えば4個適宜間隔を有して形成されている。該上部軸穴11には雌ねじが刻設されている。更に、該隣接する上部軸穴11間の距離L1は所望の寸法に設定されている。
【0018】
前記上部軸穴11には、付勢手段であるガススプリング12の一端、すなわちガススプリング12の上端に設けた上部取付金13が回転可能に、かつ、取り外し可能に連結されている。該連結部は、図5及び図6に示すように、スパナ等の工具を係止できるように平面部を有する回転部14の両端に雄ねじ15,16を突設した上部軸17を設け、該上部軸17の雄ねじ15を前記上部軸穴11に螺着し、その後、上部軸17に前記上部取付金13を挿通し、その後、雄ねじ16にナット18を螺着して、上部取付金13を腕8に回転可能に、かつ、取り外し可能に連結するようになっている。
【0019】
前記ガススプリング12の他端、すなわち、ガススプリング12のロッド12aの下端に設けた下部取付金具19は、扉1の側枠1a、すなわち、前記腕軸取付金9が付設された側に取り付けられた支持部材である下部軸取付金20に移動調整可能に連結されている。該連結部は、下部軸取付金具20に水平方向の長穴状の下部軸穴21を形成し、該下部軸穴21に下部軸22を下部軸穴21の長手方向に移動可能に挿通し、下部軸22に設けた部材23とナット24とで下部取付金具19を挟持し、また下部軸22に下部取付金具19を回転可能に挿通して形成されている。
【0020】
したがって、ナット24を緩めることにより下部軸22を下部軸穴21の長手方向に移動して下部軸22を所望の位置の波形面21aに係止でき、また、その所望の移動位置においてナット24を締め付けることにより、その下部軸22の位置を固定できるようになっている。
【0021】
更に、前記下部軸穴21の下辺には、複数の凹凸からなる波形面21aが、長手方向、すなわち、水平方向に形成されている。該波形面21aの隣接する山部間の距離L2は、前記上部軸穴11間の距離L1よりも短く設定されているとともに距離L2間に前記下部軸22が嵌合係止する凹面が形成されている。すなわち、下部軸22を距離L2の間隔で移動して山部間に係止できるようになっている。
【0022】
前記ガススプリング12は、前記上部軸17と下部軸22を、これらの間が広がる方向へ所定圧で付勢(反発)するようにガス圧が設定されており、この所定圧以上(押し縮め力)が上部軸17と下部軸22間に作用すると所定圧の反発力を保持しながらロッド12aが退入し、上部軸17と下部軸22間に作用する圧力(押し縮め力)が前記所定圧以下になると所定圧の反発力を保持してロッド12aが進出して、常に上部軸17の上方への押圧力(反発力)が一定になるようになっている。
【0023】
以上の構造において、ガススプリング12における上部軸17と下部軸22の取り付け位置が図の状態において、ガススプリング12の反発力による腕8の上方への反発力と落とし窓4の下降力(自重)とのバランスがとれている状態の場合には、人力により落とし窓2を軽く上下に開閉することができる。
【0024】
また、前記の上部軸17と下部軸22の取り付け位置では落とし窓4の人力による上昇操作が重い場合には、上部軸17を、図の位置よりも上方に形成した上部軸穴11a又は11b(図5参照)に嵌め変えて調整するか、または下部軸22を、図の位置よりも右方側へ移動して調整する。
【0025】
前記上部軸17の嵌め変え操作は、先ず回転部14をスパナ等の工具によって回転して雄ねじ15を腕8より外し、次に、その雄ねじ15を上部軸穴11a又は11bに位置させ、回転部14をスパナ等により回転して雄ねじ15を上部軸穴11a又は12aに螺着する。
【0026】
また、下部軸22を移動させるには、ナット24を緩めて下部軸22を下部軸穴21に沿って左方へ所望量移動して波形面21aの凹部に係合させ、その位置においてナット24を締め付ける。
【0027】
また、前記図における上部軸17と下部軸22の取り付け位置では落とし窓4の自重による下降力よりもガススプリング12の反発力による腕の反発力が大きい場合、すなわち、落とし窓4の人力による下降操作が重い場合には、上部軸17を、図の位置よりも下方に形成した上部軸穴11c(図5参照)に嵌め変えて調整するか、または下部軸22を、図の位置よりも左方側へ移動して調整する。
【0028】
この上部軸17の嵌め変え操作及び下部軸22の移動操作は前記と同様に行う。
【0029】
また、前記の調整量がかなり大きく必要な場合には上部軸17の嵌め変えで行い、微調整を必要とする場合には下部軸22の移動により行う。
【0030】
したがって、調整は、先ず上部軸17によって大きく調整しておき、次に波形面21aにガススプリング12の付勢力によって波形面21aに押し付けられている下部軸22を、ナット24を締めて1波面ずつ滑らせて移動しつつ、落とし窓4の軽重を確認し、バランスがとれた位置でナット24を締め付けて下部軸22を固定する。
【0031】
以上の操作により、バランス調整が極めて容易に行うことができる
【0039】
なお、前記実施例では、上方への付勢手段としてガススプリング12を用いたが、この付勢手段をガススプリング12に代えて、エア又はオイルにより作動するアクチュエータを用いてもよい。
【0040】
すなわち、鉄道車両における複数の窓を同時に自動的に上下に開閉するために各窓毎に昇降用のアクチュエータを設けた場合、各窓部の製造によって各窓毎に自重による下降力が異なる場合がある。このような場合に、アクチュエータの上下端に前記実施例のような調整機構を設けることにより、各窓毎にバランス調整を行うことができる。
【0041】
また、図に示す実施例は落とし窓に適用した例であるが、本発明は落とし窓に限ることなく、落とし窓を含む上下に開閉する窓に適用できるものである。
【0042】
【発明の効果】
以上のようであるから本発明によれば、バランサー装置を、前記従来の構造に比べて、部品点数が少なく簡易な構造で形成できるため、荷重、モーメント計算が容易に設計、製作がしやすく、しかもバランス調整が容易になる。したがって、日常の保守に多くの効果をもたらすものである。

It is connected rotatably. The arm 8 swings between an ascending state A inclined as shown by a solid line in FIG. 2 and a descending state B inclined as shown by a chain line with the arm shaft 10 as a center. The horizontal state is indicated by C.
[0017]
An upper shaft hole 11 is formed in the arm 8, and in the illustrated embodiment, a plurality of, for example, four, are formed at appropriate intervals along the longitudinal direction of the arm 8 in the lower part of the arm 8. . An internal thread is engraved in the upper shaft hole 11. Further, the distance L1 between the adjacent upper shaft holes 11 is set to a desired dimension.
[0018]
An upper mounting metal 13 provided at one end of a gas spring 12 as an urging means, that is, an upper end of the gas spring 12 is rotatably and detachably connected to the upper shaft hole 11. As shown in FIGS. 5 and 6, the connecting portion is provided with an upper shaft 17 projecting male screws 15 and 16 at both ends of a rotating portion 14 having a flat portion so that a tool such as a spanner can be locked, The male screw 15 of the upper shaft 17 is screwed into the upper shaft hole 11, and then the upper mounting metal 13 is inserted into the upper shaft 17, and then the nut 18 is screwed to the male screw 16, and the upper mounting metal 13 is attached. The arm 8 is rotatably and detachably connected.
[0019]
The lower mounting bracket 19 provided at the other end of the gas spring 12, that is, the lower end of the rod 12a of the gas spring 12, is attached to the side frame 1a of the door 1, that is, the side to which the arm shaft mounting bracket 9 is attached. It is connected to a lower shaft mounting metal 20 which is a supporting member so as to be movable and adjustable. The connecting portion forms a lower shaft hole 21 in the shape of a horizontally elongated hole in the lower shaft mounting bracket 20, and the lower shaft 22 is inserted into the lower shaft hole 21 so as to be movable in the longitudinal direction of the lower shaft hole 21. The lower mounting bracket 19 is sandwiched between a member 23 and a nut 24 provided on the lower shaft 22, and the lower mounting bracket 19 is rotatably inserted into the lower shaft 22.
[0020]
Therefore, by loosening the nut 24, the lower shaft 22 can be moved in the longitudinal direction of the lower shaft hole 21 so that the lower shaft 22 can be locked to the corrugated surface 21a at a desired position. By tightening, the position of the lower shaft 22 can be fixed.
[0021]
Further, on the lower side of the lower shaft hole 21, a corrugated surface 21a composed of a plurality of irregularities is formed in the longitudinal direction, that is, in the horizontal direction. A distance L2 between adjacent ridges of the corrugated surface 21a is set to be shorter than a distance L1 between the upper shaft holes 11, and a concave surface is formed between the distance L2 to which the lower shaft 22 is fitted and locked. ing. That is, the lower shaft 22 can be moved between the peaks by moving at a distance L2.
[0022]

The rod 12a moves forward while maintaining a repulsive force of a predetermined pressure below, so that the pressing force (repulsive force) upward of the upper shaft 17 is always constant.
[0023]
In the above structure, when the upper shaft 17 and the lower shaft 22 are attached to the gas spring 12 in the state shown in the figure, the repulsive force upward of the arm 8 due to the repulsive force of the gas spring 12 and the downward force (self-weight) of the drop window 4 Can be opened and closed lightly up and down by human power.
[0024]
In addition, when the lifting operation by the manpower of the drop window 4 is heavy at the attachment position of the upper shaft 17 and the lower shaft 22, the upper shaft hole 11a or 11b ( (Refer to FIG. 5), or adjust by moving the lower shaft 22 to the right side of the position in the figure.
[0025]
The operation of changing the fitting of the upper shaft 17 is performed by first rotating the rotating portion 14 with a tool such as a spanner to remove the male screw 15 from the arm 8, and then positioning the male screw 15 in the upper shaft hole 11a or 11b. 14 is rotated by a spanner or the like, and the male screw 15 is screwed into the upper shaft hole 11a or 12a.
[0026]

[0029]
Further, when the adjustment amount is required to be considerably large, it is performed by changing the fitting of the upper shaft 17, and when fine adjustment is necessary, it is performed by moving the lower shaft 22.
[0030]
Therefore, the adjustment is first made largely by adjusting the upper shaft 17, and then the lower shaft 22 pressed against the corrugated surface 21 a by the urging force of the gas spring 12 is tightened on the corrugated surface 21 a, and the nut 24 is tightened one wave surface at a time. While sliding, the weight of the drop window 4 is confirmed, and the nut 24 is tightened at a balanced position to fix the lower shaft 22.
[0031]
With the above operation, balance adjustment can be performed very easily .
[0039]
In the above embodiment, the gas spring 12 is used as the upward biasing means. However, instead of the biasing means, the gas spring 12 may be replaced with an actuator that operates with air or oil.
[0040]
That is, when an actuator for raising and lowering is provided for each window in order to automatically open and close a plurality of windows in a railway vehicle at the same time, the downward force due to its own weight may differ for each window due to the manufacture of each window part. is there. In such a case, balance adjustment can be performed for each window by providing the adjustment mechanism as in the above-described embodiment at the upper and lower ends of the actuator.
