It is possible to prevent the vehicle from being tilted or derailed due to dropping of the wheel holding member or the like. That is, even in an emergency state, the vehicle can travel to a safe place (a low position such as a platform).

以下、実施の形態を示す図面に基づき本発明を詳説する。
図１は本発明の乗物装置の第１の実施形態の正面から見た要部断面図である。
本発明の乗物装置は、ジェットコースター等の遊戯用の車両１と、これが走行する高架状の軌条２ａを備えている。軌条２ａは左右一対に設けられ、軌道２を構成している。
車両１は、軌条２ａに転動する複数の車輪12と、その複数の車輪12を保持する車輪保持部材20と、車輪保持部材20が外嵌状に枢着される車軸10と、を備えている。車両１は、軌条２ａに上下方向及び左右外方の３方向から接触可能な複数の車輪12によって、軌道２から脱線せずに走行可能に設けられている。 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
FIG. 1 is a cross-sectional view of an essential part of a vehicle apparatus according to a first embodiment of the present invention viewed from the front.
The vehicle apparatus of the present invention includes a play vehicle 1 such as a roller coaster and an elevated rail 2a on which the vehicle travels. The rails 2 a are provided in a pair of left and right, and constitute the track 2.
The vehicle 1 includes a plurality of wheels 12 that roll on the rail 2a, a wheel holding member 20 that holds the plurality of wheels 12, and an axle 10 on which the wheel holding member 20 is pivotally attached. Yes. The vehicle 1 is provided so as to be able to travel without derailing from the track 2 by a plurality of wheels 12 that can come into contact with the rail 2a from the three directions of the vertical direction and the left and right outward directions.

車輪保持部材20は、車軸10が挿通可能な円筒状ボス部21を有している。車軸10に円筒状ボス部21を外嵌させることで、車軸10の軸心Ｌ10周りに揺動するものである。例えば、軌条２ａの上面に転動する支持車輪12Ａ，12Ａは、前後方向に分かれて２個ずつ各車輪保持部材20に枢着されている。また、軌条２ａの外側面に転動する案内車輪12Ｂ，12Ｂは前後方向に分かれて２個ずつ車輪保持部材20に枢着されている。これによって、カーブや宙返り等の複雑な軌道２であっても車両１が確実に案内されつつ走行する。 The wheel holding member 20 has a cylindrical boss portion 21 into which the axle 10 can be inserted. The cylindrical boss portion 21 is externally fitted to the axle 10 to swing around the axis L 10 of the axle 10. For example, the support wheels 12A and 12A that roll on the upper surface of the rail 2a are separated in the front-rear direction and are pivotally attached to each wheel holding member 20 two by two. Further, the guide wheels 12B, 12B rolling on the outer surface of the rail 2a are separated in the front-rear direction and are pivotally attached to the wheel holding member 20 two by two. As a result, the vehicle 1 travels while being reliably guided even on a complicated track 2 such as a curve or somersault.

そして、本発明の乗物装置は、仮に、車軸10が破断する（破損した）緊急状態で、車軸10の破断した車軸先端部10Ａ及び車輪保持部材20が、脱落するのを防止すると共に、車軸10が破断後も、車両１を軌道２に走行させることが可能な安全手段30を備えている。   The vehicle apparatus according to the present invention prevents the axle tip portion 10A and the wheel holding member 20 from being broken off in the emergency state in which the axle 10 is broken (broken). Is provided with safety means 30 that allows the vehicle 1 to travel on the track 2 even after breaking.

安全手段30は、車輪保持部材20の円筒状ボス部21の内端側（車軸10の軸心Ｌ10の左右内方側）に突設された外鍔部31と、車軸堅牢部10Ｂに付設され（上述の緊急状態において）外鍔部31に係止可能な軸心外方向移動阻止部材32と、を備えている。 Safety means 30 includes an outer flange portion 31 projecting from the (right and left inner side of the axis L 10 of the axle 10) the inner end of the cylindrical boss portion 21 of the wheel holding member 20, attached to the axle robust unit 10B And (in the above-described emergency state) an axially outward movement blocking member 32 that can be locked to the outer flange 31.

軸心外方向移動阻止部材32が付設される車軸堅牢部10Ｂとは、車軸10の車輪保持部材20が枢着される近傍かつ車軸10の基端（軸心Ｌ10の左右内方）寄りで、断面係数が大きい部分や、車両１からの繰り返し荷重や金属疲労に強い部分（部位）等の破断の虞が低い（破壊される心配の少ない）部分である。つまり、車軸10が破断する緊急状態では、車両１側に（車体９に取着されたまま）残存する車軸10の部分（部位）である。 The axle robust unit 10B that axial epicardial movement blocking member 32 is attached, (right and left inward of the axis L 10) the proximal end of the near and the axle 10 of the wheel holding member 20 is pivotally mounted in the axle 10 in close A portion having a large section modulus or a portion (part) resistant to repeated load or metal fatigue from the vehicle 1 is less likely to be broken (has little fear of being broken). That is, in an emergency state where the axle 10 is broken, it is a portion (part) of the axle 10 that remains on the vehicle 1 side (while attached to the vehicle body 9).

外鍔部31は、リング状の円環部材を、円筒状ボス部21の内端側の外周に外嵌し、溶接等により固着して形成したものである。
なお、外鍔部31は、車輪保持部材20を製作する際、例えば鍛造や鋳造又は機械加工にて、円筒状ボス部21と一体状に形成しても良い。 The outer collar portion 31 is formed by fitting a ring-shaped annular member to the outer periphery on the inner end side of the cylindrical boss portion 21 and fixing it by welding or the like.
The outer flange portion 31 may be formed integrally with the cylindrical boss portion 21 by, for example, forging, casting or machining when the wheel holding member 20 is manufactured.

軸心外方向移動阻止部材32は、図１及び図２と図３に示すように、緊急状態で外鍔部31に係止可能な円弧状の爪部32ａを有している。爪部32ａは、ボス部21の外周面の半径に対して僅かに大きな曲率半径の円弧に形成されている。つまり、ボス部21の外周面に接近して、外鍔部31（の軸心Ｌ10の外方側の面）に広く接触可能（係り代が大きくなるよう）に形成されている。 As shown in FIGS. 1, 2, and 3, the off-axis direction movement blocking member 32 has an arcuate claw portion 32 a that can be locked to the outer flange portion 31 in an emergency state. The claw portion 32 a is formed in an arc having a slightly larger curvature radius than the radius of the outer peripheral surface of the boss portion 21. In other words, close to the outer peripheral surface of the boss portion 21 is formed in a widely accessible (so that engagement allowance increases) in the outer collar portion 31 (the surface of the outer side of the axis L 10 in).

爪部32ａは、車軸10が破損していない正常な状態で、外鍔部31に当接せず、所定の間隙（クリアランス）をもって配設されている。爪部32ａと外鍔部31とは、車軸10の軸心方向に所定の間隙を形成している。爪部32ａとボス部21の外周面とは、車軸10のラジアル外方向に所定の間隙を形成している。つまり、爪部32ａは、正常な状態で車輪保持部材20の揺動に干渉しないように設けられ、かつ、緊急状態で外鍔部31に係止可能に設けられている。言い換えると、阻止部材32を外鍔部31に対して所定の間隙をもって包囲状に配設している。   The claw portion 32a is disposed with a predetermined gap (clearance) without contacting the outer flange portion 31 in a normal state where the axle 10 is not damaged. The claw portion 32 a and the outer flange portion 31 form a predetermined gap in the axial direction of the axle 10. The claw portion 32a and the outer peripheral surface of the boss portion 21 form a predetermined gap in the radially outward direction of the axle 10. That is, the claw portion 32a is provided so as not to interfere with the swing of the wheel holding member 20 in a normal state, and is provided so as to be able to be locked to the outer flange portion 31 in an emergency state. In other words, the blocking member 32 is disposed in a surrounding shape with a predetermined gap with respect to the outer flange portion 31.

また、阻止部材32は、１つの外鍔部31を上下方向から挟むように（１８０度対称位置に）２箇所に配設されている。緊急状態で、車体９の荷重を、車軸10の破断した車軸先端部10Ａに替わって車輪保持部材20に伝達し、車輪保持部材20（の車輪12）に車体９（車両１）の荷重を支持する。   In addition, the blocking member 32 is disposed at two locations so as to sandwich one outer flange portion 31 from the vertical direction (at a 180-degree symmetrical position). In an emergency state, the load of the vehicle body 9 is transmitted to the wheel holding member 20 instead of the broken axle tip portion 10A of the axle 10, and the load of the vehicle body 9 (vehicle 1) is supported by the wheel holding member 20 (the wheel 12). To do.

阻止部材32は、板状の取付部材33が固着されている。取付部材33は、側面視円弧状に形成され、貫通孔33ａを貫設している。また、取付部材33は、車軸堅牢部10Ｂに外嵌状に固着されるフランジ部材34にボルト・ナット結合等によって取着されている。つまり、阻止部材32は、車軸堅牢部10Ｂに取付部材33及びフランジ部材34を介して着脱可能に付設されている。フランジ部材34は図３に示すように、くびれ部を有する矩形の板状部材であって、取付部材33の貫通孔33ａと同心状に配設される貫孔34ａを有している。   The blocking member 32 has a plate-like attachment member 33 fixed thereto. The attachment member 33 is formed in an arc shape when viewed from the side, and penetrates the through hole 33a. The attachment member 33 is attached to a flange member 34 that is fixed to the axle fastened portion 10B in an outer fitting manner by bolt / nut coupling or the like. That is, the blocking member 32 is detachably attached to the axle fastened portion 10B via the attachment member 33 and the flange member 34. As shown in FIG. 3, the flange member 34 is a rectangular plate-like member having a constricted portion, and has a through hole 34 a disposed concentrically with the through hole 33 a of the mounting member 33.

即ち、取付部材33の貫通孔33ａ及びフランジ部材34の貫孔34ａに挿通させた図示省略のボルト部材と、ナット部材と、を共働きさせることで、阻止部材32は、取付部材33を介して、フランジ部材34に取着（付設）されている。つまり、阻止部材32は、車軸堅牢部10Ｂにボルト・ナット結合をもって着脱可能に付設されている。
なお、取付部材33又はフランジ部材34のどちらか一方にネジ孔を形成し、そのネジ孔に他方の部材を挿通したボルト部材を螺着させることで、取付部材33及びフランジ部材34を介して、阻止部材32を着脱可能に車軸堅牢部10Ｂに付設しても良い。
即ち、阻止部材32は、メンテナンスや検査等の保守・点検の為に、車輪保持部材20を車軸10から取り外せるように、着脱可能に設けている。なお、図１に於て、５，５は滑り軸受（ブッシュ）を示す。そして、車軸10は一体ものの場合を示している。 That is, by preventing the bolt member (not shown) inserted through the through-hole 33a of the mounting member 33 and the through-hole 34a of the flange member 34 and the nut member from working together, the blocking member 32 is interposed via the mounting member 33. It is attached (attached) to the flange member 34. That is, the blocking member 32 is detachably attached to the axle fastened portion 10B with a bolt and nut connection.
In addition, by forming a screw hole in one of the attachment member 33 or the flange member 34 and screwing a bolt member inserted through the other member into the screw hole, via the attachment member 33 and the flange member 34, The blocking member 32 may be detachably attached to the axle fastened portion 10B.
That is, the blocking member 32 is detachably provided so that the wheel holding member 20 can be detached from the axle 10 for maintenance and inspection such as maintenance and inspection. In FIG. 1, reference numerals 5 and 5 denote sliding bearings (bushes). The axle 10 is shown as an integral unit.

本発明の乗物装置の使用方法（作用）について説明する。
仮に、車軸10が（車輪保持部材20近傍で車軸10の段差部等の応力集中部で）破断する緊急状態となった場合、車軸堅牢部10Ｂは、車両１側に（車体９に取着されたまま）残存し、車軸10の破断した車軸先端部10Ａ及び車輪保持部材20は、軸心外方向（軸心Ｌ10の左右外方向側）に移動しようとする。 A method (action) for using the vehicle apparatus of the present invention will be described.
If the axle 10 enters an emergency state in which it breaks (at a stress concentration portion such as a stepped portion of the axle 10 near the wheel holding member 20), the axle fastened portion 10B is attached to the vehicle 1 (attached to the vehicle body 9). Remaining), the broken axle tip 10A and the wheel holding member 20 of the axle 10 tend to move in the axially outward direction (the laterally outward direction side of the axial center L10).

ところが、本発明の乗物装置は、安全手段30によって、車軸10の破断した車軸先端部10Ａ及び車輪保持部材20は軸心外方向の移動を阻止する。
つまり、破断した車軸先端部10Ａに外嵌したままの車輪保持部材20が軸心外方向に移動すると、外鍔部31が、阻止部材32の爪部32ａに当接する（引っ掛かる）。阻止部材32は、車輪保持部材20が軸心外方向へ移動するのを阻止（規制）する。 However, in the vehicle apparatus of the present invention, the safety shaft 30 prevents the broken axle tip portion 10A and the wheel holding member 20 of the axle 10 from moving in the axial direction.
That is, when the wheel holding member 20 that is externally fitted to the broken axle tip portion 10A moves in the axial direction, the outer flange portion 31 comes into contact with (hooks) the claw portion 32a of the blocking member 32. The blocking member 32 blocks (regulates) the wheel holding member 20 from moving in the axial direction.

外鍔部31及び阻止部材32を備えた安全手段30が、車輪保持部材20等の軸心外方向への移動を阻止し、車両１から車輪保持部材20等が脱落するのを防止する。車軸10の破断した車両１は、破断する前に近い姿勢で、車輪保持部材20を介して軌条２ａに走行可能に保持される。言い換えると、車軸10が破断しても、複数の車輪12は、軌条２ａに転動可能な状態で保持される。   The safety means 30 including the outer flange portion 31 and the blocking member 32 prevents the wheel holding member 20 and the like from moving in the axial direction, and prevents the wheel holding member 20 and the like from dropping from the vehicle 1. The vehicle 1 with the axle 10 broken is held by the rail 2a through the wheel holding member 20 in a posture close to that before breaking. In other words, even if the axle 10 is broken, the plurality of wheels 12 are held in a rollable state on the rail 2a.

車軸10の破断時に、車両１の荷重のバランスが崩れ、破損した側に大きく傾倒しようとするが、大きく傾倒する前に、車軸10の破断した車軸先端部10Ａに替わって、阻止部材32が外鍔部31に接触して傾倒を防止する。乗客同士が衝突したり、投げ出されるような強い衝撃が発生するのを防止する。つまり、安全手段30は、車両１を車軸10が破断する前（正常な状態）に近い姿勢に保持させ、軌道２からの脱線を防止する。脱落や横転等の大きな脱線を防止し、重大な事故が発生するのを防止する。   When the axle 10 breaks, the balance of the load of the vehicle 1 is lost, and it tries to tilt greatly to the damaged side. However, before the tilting, the blocking member 32 is replaced with the broken axle tip 10A. Contact the buttocks 31 to prevent tilting. It prevents the occurrence of strong impacts such as passengers colliding with each other or thrown out. That is, the safety means 30 keeps the vehicle 1 in a posture close to that before the axle 10 breaks (normal state) and prevents derailment from the track 2. Prevent major derailments such as dropouts and rollovers and prevent serious accidents.

また、乗客の姿勢が苦しい箇所での車両１の停車や、脱線を防止し、乗客を救助に適した所定の位置（プラットホーム及び乗降場や軌道２が平坦な低位置等）に搬送する。   In addition, the vehicle 1 is stopped or derailed at a place where the posture of the passenger is difficult, and the passenger is transported to a predetermined position suitable for rescue (such as a platform and a landing / low position where the track 2 is flat).

また、車軸10や車輪保持部材20を保守及び点検や交換する際に、阻止部材32を取り外すことで、軸心外方向へ移動できる。   Further, when the axle 10 and the wheel holding member 20 are maintained, inspected, and exchanged, the blocking member 32 can be removed to move in the direction outside the axis.

次に、本発明の乗物装置の第２の実施の形態について説明する。
図４の要部断面正面図に於て、車両１は、軌条２ａに転動する複数の車輪12と、その複数の車輪12を保持する車輪保持部材20と、車輪保持部材20を枢着するための車軸10を有する車体９と、を備えている。ここで、車軸10は、車体９に取着されるアーム部材15と、アーム部材15の先端側に固着される軸部材16と、を備えたものである。アーム部材15の形状は、矩形パイプ形状ものや円筒形状である。そして、ナット17等によって、軸部材16がアーム部材15に固着され、また、円錐ころ軸受18，18にて、軸部材16に車輪保持部材20が揺動可能に枢着されている。 Next, a second embodiment of the vehicle apparatus of the present invention will be described.
4, the vehicle 1 pivotally attaches a plurality of wheels 12 that roll on the rail 2a, a wheel holding member 20 that holds the plurality of wheels 12, and a wheel holding member 20. And a vehicle body 9 having an axle 10 for the purpose. Here, the axle 10 includes an arm member 15 attached to the vehicle body 9 and a shaft member 16 fixed to the distal end side of the arm member 15. The shape of the arm member 15 is a rectangular pipe shape or a cylindrical shape. The shaft member 16 is fixed to the arm member 15 by a nut 17 or the like, and the wheel holding member 20 is pivotally attached to the shaft member 16 by the tapered roller bearings 18 and 18.

そして、外鍔部31と軸心外方向移動阻止部材32とを備え、かつ、車軸10が破断する緊急状態で、車輪保持部材20等が脱落するのを防止する安全手段30を備えている。   In addition, a safety means 30 is provided that includes an outer flange portion 31 and an axial center direction movement prevention member 32, and prevents the wheel holding member 20 and the like from falling off in an emergency state in which the axle 10 is broken.

外鍔部31は、リング状の円環部材を、円筒状ボス部21の内端側の端面に溶接等により固着して形成したものである。なお、外鍔部31は、円筒状ボス部21と一体状に形成しても良い。   The outer collar portion 31 is formed by fixing a ring-shaped annular member to the end surface on the inner end side of the cylindrical boss portion 21 by welding or the like. The outer flange portion 31 may be formed integrally with the cylindrical boss portion 21.

軸心外方向移動阻止部材32は、車軸10の車軸堅牢部10Ｂであるアーム部材15に固着されている。阻止部材32は、図４及び図５に示すように、緊急状態で外鍔部31に係止可能な円弧状の爪部32ａを有している。また、車軸堅牢部10Ｂに付設するための取付孔32ｂが貫設されている。阻止部材32は、車軸堅牢部10Ｂ（アーム部材15）に設けられたネジ孔に、取付孔32ｂを挿通した取付ボルト部材35を螺着させることで、着脱可能に取着されている。   The off-axis direction movement prevention member 32 is fixed to the arm member 15 which is the axle solid portion 10B of the axle 10. As shown in FIGS. 4 and 5, the blocking member 32 has an arcuate claw portion 32 a that can be locked to the outer flange portion 31 in an emergency state. Further, a mounting hole 32b is provided through the axle fastened portion 10B. The blocking member 32 is detachably attached by screwing a mounting bolt member 35 inserted through the mounting hole 32b into a screw hole provided in the axle fastened portion 10B (arm member 15).

第２の実施の形態の乗物装置の作用について説明する。
仮に、車軸10が（車輪保持部材20近傍で車軸10の段差部等の応力集中部で）破断する緊急状態となった場合、車軸堅牢部10Ｂ（アーム部材15）は、車両１側に残存し、車輪保持部材20及び車軸10の破断した車軸先端部10Ａ（軸部材16のボス部21挿通部分）は、車両１から離脱する方向（軸心外方向）に移動しようとする。 The operation of the vehicle apparatus of the second embodiment will be described.
If the axle 10 enters an emergency state in which it breaks (at a stress concentration portion such as a stepped portion of the axle 10 near the wheel holding member 20), the axle fastened portion 10B (arm member 15) remains on the vehicle 1 side. The wheel holding member 20 and the axle tip portion 10A where the axle 10 is broken (the boss portion 21 insertion portion of the shaft member 16) tends to move in the direction away from the vehicle 1 (the direction outside the axis).

ところが、安全手段30によって、車軸10の破断した車軸先端部10Ａ及び車輪保持部材20は軸心外方向の移動を阻止する。外鍔部31が阻止部材32の爪部32ａに当接して、車輪保持部材20等の軸心外方向への移動が阻止される。車軸10が破断する緊急状態であっても、車両１を乗客が安全な姿勢な状態に保持しつつ軌条２ａに沿って走行可能にする。   However, the safety means 30 prevents the axle tip 10A and the wheel holding member 20 from breaking the axle 10 from moving in the axial direction.
