Description

【０００１】
【発明の属する技術分野】
本発明は鉄道軌道の分岐器における基本レールや伸縮継目における受けレール・トングレールのように横圧を受けるレールの弾性締結装置に関する。
【０００２】
【従来の技術】
従来から床板と、前記床板上に載置されるとともに横圧を受けるレールに当接する立上り部および前記レールの底部上への当接部を有する剛性のレールブレスと、前記床板上に固着若しくは一体形成して立設された平面コ字状の係止金具と、両側の折返部が前記係止金具の凹部に係止されるとともに中央折返部が前記係止金具のゲート部下面から突出して前記レールブレスにばね圧で押圧するＷ字状の線ばねクリップとからなる横圧を受けるレールの弾性締結装置が知られている。
【０００３】
前記従来例はＷ字状の線ばねクリップの中央折返部が厚肉のレールブレス上で、しかも横圧を受けるレールの底部外に位置するため、前記レールにかかるばね圧が小さく、そのためレールブレスの立上り部をレールのあご部に当接するように延出したり、レールブレスの後端をストッパで支持したり、前記レールブレスと前記中央折返部間に緩み止め座金を介在させる等、部品数が多い。
【０００４】
また他の従来例として、床板に固定された前記平面コ字状の係止金具内にレールブレスを挿通し、前記Ｗ字状の線ばねクリップで厚肉のレールブレス上面を押圧しているものも知られているが、これではレールブレスの立上り部をレールに強く押付けることができず、このためレールブレスの後部に緩め止め座金を噛ませる等、この場合も部品数が多くなる。したがって従来例はいずれも制作費が高くなるとともに組立て作業を迅速にすることができない。
【０００５】
【発明が解決しようとする課題】
本発明は従来例の前記欠点を解消することを課題とするもので、レールブレスの支持力を大きくするとともにＷ字状の線ばねクリップの押圧力を効率良くし、少ない部品数で安定良くレールを支持できるようにすることを課題とする。
【０００６】
【課題を解決するための手段】
本発明は床板と、前記床板上に載置されるとともに横圧を受けるレールに当接する立上り部および前記レールの底部上への当接部を有する剛性のレールブレスと、前記床板上に固着若しくは一体形成して立設された平面コ字状の係止金具と、両側の折返部が前記係止金具の凹部に係止されるとともに中央折返部が前記係止金具のゲート部下面から突出して前記レールブレスにばね圧で押圧するＷ字状の線ばねクリップとからなる横圧を受けるレールの弾性締結装置において、前記床板の上面に傾斜溝を設け、前記レールブレスを平面コ字状に形成して開口部を形成し、しかも前記レールブレスを側面Ｌ字状に形成するとともに前記立上り部を前記レールの腹部に当接する高さに形成し、また前記立上り部から前記開口部に向け、かつ前記レールの底部上に位置する下段部を連設し、前記レールブレスの後部下端に前記傾斜溝に摺動自在な挿入脚を形成し、また前記係止金具を前記開口部内で、かつ前記レールに対して直角方向位置に設け、さらに前記Ｗ字状の線ばねクリップの中央折返部を前記下段部を介して前記レールの底部の真上からばね圧で押圧することを特徴とする。
【０００７】
床板上に立設している係止金具に開口部を有するレールブレスを落とし込むとともに床板の傾斜溝に挿入脚を嵌入し、レールブレスの側板をハンマー等で打つ。ここに挿入脚が傾斜溝に案内されて摺動するため、楔作用を生じ、レールブレスの立上り部はレールの腹部に強く圧接する。続いてＷ字状の線ばねクリップを外方から係止金具に押込めば、両側の折返部が係止金具の凹部に係止されるとともに中央折返部が係止金具のゲート部下面から突出してレールブレスの下段部上を弾性で押圧し、レールブレスの両側板より遙かに低く、しかもレールの底部の真上にある下段部を介してレールブレスの当接部がレールの底部を確実に押圧する。
【０００８】
前記本発明の手段では前記下段部の端縁の形状を特定するものではないが、レールブレスの下段部の端縁が床板の傾斜溝に平行であることが好ましい。
【０００９】
このようにすれば、レールブレスがいずれの位置にあっても、線ばねクリップの中央折返部と下段部との接触面積が同一となり、押圧力が一定となり、安定性が良い。
【００１０】
【発明の実施の形態】
図で示す例は分岐器における本発明の実施の形態を示すもので、図示を省略したまくらぎ上に可変パッド６、軌道パッド７を介して床板１が図示を省略した手段により取付けられている。床板１上には凹溝１２および傾斜溝１１が形成され、横圧を受けるレール２として基本レールが凹溝１２底部に載置されるとともに図２で示すように底部２１の左端が凹溝１２端および床板１上に固着された上部床板１′により係止されている。なお符号８はトングレールであり、図２の矢印で示すように図示を省略した転てつ器により上部床板１′上を左右動し、図１、２では基本レールに当接した状態を示している。
【００１１】
凹溝１２底部には平面コ字状の係止金具４が溶接によりレール１に対して直角位置に固定されて床板１上に立設されている。この係止金具４は後述するレールブレス３の両側板３６、３６より高さが低く形成されている市販のものである。この係止金具４の両側にはそれぞれ凹部４０、４０が形成され、上部内方にゲート部４１が形成されている。
【００１２】
図中、符号３は剛性のレールブレスであり、レールブレス３は平面コ字状で開口部３３を有する。またレールブレス３は立上り部３０と両側板３６、３６を略Ｌ字状に一体形成して成り、立上り部３０の高さはレール２の腹部２０に当接するものであり、立上り部３０から開口部３３に向けて各側板３６より低い下段部３４が連設され、しかもこの下段部３４はレール２の底部２１上に当接する距離を有し、下段部３４の端縁３５は床板１の傾斜溝１１に平行であり、レールブレス３の後部下端に傾斜溝１１に摺動自在な挿入脚３２が両側板３６、３６と一体的に掛設されている。
【００１３】
図中、符号５はばね鋼線からなるＷ字状の線ばねクリップであり、前記係止金具４と線ばねクリップ５は公知のものである。
【００１４】
次に本発明の弾性締結装置の組立法および作用を説明すれば、床板１上に立設している係止金具４にＷ字状の線ばねクリップ５の中央折返部５１がレール２に差しかかる直前まで取付けておく。そしてレール２を床板１上に配置する。次に開口部３を有するレールブレス３を係止金具４に落とし込むとともに床板１の傾斜溝１１に挿入脚３２を挿入し、レールブレス３の側板３６をハンマー等で打つ。ここに挿入脚３２が傾斜溝１１に案内されて摺動するため、楔作用を生じ、レールブレス３の立上り部３０はレール２の腹部２０に強く圧接する。続いてＷ字状の線ばねクリップ５を外方から係止金具４にさらに押込めば、両側の折返部５０が係止金具４の凹部４０、４０に確実に係止されるとともに中央折返部５１が係止金具４のゲート部４１下面から突出してレールブレス３の下段部３４上を弾性で押圧し、レールブレス３の両側板３６、３６より遙かに低く、しかもレール２の底部２１の真上にある下段部３４を介してレールブレス３の当接部３１がレール２の底部２１を確実に押圧する。
【００１５】
なお前記の実施の形態では分岐器の場合を例にとって本発明の弾性締結装置について説明したが、伸縮継目の場合には、レール２が受けレールまたはトングレールとなり、分岐器用のトングレール８がなく本発明の弾性締結装置の構造、組立法、作用については分岐器の場合と同一である。
【００１６】
【発明の効果】
本発明のうち請求項１の発明によれば、レールブレスが楔作用によりレール腹部に強く当接するとともに線ばねクリップの弾性作用が下段部という側板より低く、しかもレール底部の真上に強く働き、横圧に対して充分に耐えることができ、従来例のようにレールの支持力が小さいため立上り部をレールのあご部まで延出したり、ストッパや緩み止め座金のような部品も不要であり、部品数が少なく、安価、迅速かつ容易に製造および組立てをすることができる。また係止金具をレールに対して直角方向に立設するので、レールを床板に配置する以前に線ばねクリップを仮止めしておくことができ、後の作業が容易となる。
【００１７】
本発明のうち請求項２の発明によれば前記請求項１の発明の効果に加え、斜方向へのレールブレスの摺動によりレールブレスがいずれの位置にあっても線ばねクリップの中央折返部の下段部に対する当接面積は均等となり、レールをより安定かつ確実に支持することができる。

DETAILED DESCRIPTION OF THE INVENTION
The example shown in the figure shows an embodiment of the present invention in a branching device, and a floor board 1 is attached to a sleeper not shown through a variable pad 6 and a track pad 7 by means not shown. . A concave groove 12 and an inclined groove 11 are formed on the floor plate 1, and a basic rail is placed on the bottom of the concave groove 12 as a rail 2 that receives lateral pressure, and the left end of the bottom 21 is a concave groove 12 as shown in FIG. The end and the upper floor board 1 'fixed on the floor board 1 are locked. Reference numeral 8 denotes a tongrel, which is moved left and right on the upper floor plate 1 'by means of an unillustrated roller as shown by the arrow in FIG. 2, and in FIGS. ing.
[0011]
At the bottom of the concave groove 12, a U-shaped locking metal fitting 4 is fixed at a position perpendicular to the rail 1 by welding and is erected on the floor plate 1. This locking metal fitting 4 is a commercially available one that is formed to be lower than both side plates 36, 36 of the rail brace 3 described later. Concave portions 40 and 40 are formed on both sides of the locking metal fitting 4, respectively, and a gate portion 41 is formed inside the upper portion.
[0012]
In the figure, reference numeral 3 denotes a rigid rail brace, and the rail brace 3 has a U-shape and has an opening 33. The rail brace 3 is formed by integrally forming a rising portion 30 and both side plates 36, 36 in a substantially L shape, and the height of the rising portion 30 is in contact with the abdomen 20 of the rail 2, and is opened from the rising portion 30. A lower step 34 that is lower than the side plates 36 is provided continuously toward the portion 33, and the lower step 34 has a distance that contacts the bottom 21 of the rail 2, and an edge 35 of the lower step 34 is inclined to the floor plate 1. An insertion leg 32, which is parallel to the groove 11 and is slidable in the inclined groove 11 at the rear lower end of the rail brace 3, is integrally hung on both side plates 36 and 36.
[0013]
In the figure, reference numeral 5 denotes a W-shaped wire spring clip made of a spring steel wire, and the locking metal fitting 4 and the wire spring clip 5 are publicly known.
[0014]
Next, the assembly method and operation of the elastic fastening device according to the present invention will be described. The central folding portion 51 of the W-shaped wire spring clip 5 is inserted into the rail 2 on the locking metal fitting 4 standing on the floor plate 1. Install until just before this. The rail 2 is arranged on the floor board 1. Next, the rail brace 3 having the opening 3 is dropped into the locking bracket 4, the insertion leg 32 is inserted into the inclined groove 11 of the floor plate 1, and the side plate 36 of the rail brace 3 is hit with a hammer or the like. Here, since the insertion leg 32 slides while being guided by the inclined groove 11, a wedge action occurs, and the rising portion 30 of the rail brace 3 is strongly pressed against the abdominal portion 20 of the rail 2. Subsequently, when the W-shaped wire spring clip 5 is further pushed into the locking bracket 4 from the outside, the folded portions 50 on both sides are securely locked to the recesses 40, 40 of the locking bracket 4 and the central folded portion. 51 protrudes from the lower surface of the gate portion 41 of the locking metal fitting 4 and elastically presses on the lower step portion 34 of the rail brace 3, is much lower than the side plates 36, 36 of the rail brace 3, and the bottom portion 21 of the rail 2.
