Description

【０００１】
【発明の属する技術分野】
本発明は、駅のホームから乗降客や利用者が車両の連結部の隙間へ転落するのを防止するための転落防止装置に関するものである。
【０００２】
【従来の技術】
従来、この種の転落防止装置は、例えば、実開平５−９４０４７号公報には、車両の連結部に取付けられるもので、車両の連結面端部に固設した保持具に、該連結面端部に対向して取付けられるＵ字状に曲げたシート状弾性体の保護柵が開示されている。該シート状弾性体からなる対向する両保護柵によって車両の連結部の隙間を狭くして、転落事故の発生を防止している。
【０００３】
また、特開平１０−５９１７５号公報には、着脱容易に構成された平板状弾性体の転落防止保護柵が開示されている。
【０００４】
【発明が解決しようとする課題】
通常、鉄道車両の連結部の間隔は、各電鉄会社や車両の種類によって設定されていてそれら車両毎に大きく異なっている。そのため、前述した各従来例の保護柵構造では、互いに対向する保護柵の先端部を人間の通れない間隔もしくは隙間の無いように配置させるには、車両の連結間隔や軌道のカーブ条件および取付部構造に応じてサイズや形状の異なる外幌を多種類用意する必要があり、コストアップが避けられないという問題点がある。
【０００５】
しかも、実開平５−９４０４７号公報に記載の保護柵の構造では、保護柵がＵ字状に曲げられているので、車体幅方向に広くなり、車両の連結面に設置されている足掛や雨樋に干渉する。また、特開平１０−５９１７５号公報に記載の例では、着脱容易とするために、保持具に形成された溝に嵌合する膨出部が形成された形状の平板状弾性体を、前記溝に落とし込んで装着する構成であり、該保護柵を十分に締結するものではない。
【０００６】
また最近では、美観に対する注文が大きくなってきており、車両の連結部の隙間も綺麗に体裁よくカバーすることが望まれている。
【０００７】
本発明の目的は、多種類のサイズや形状のものを用意する必要がなく、各種鉄道車両の連結間隔に対応させることができ、簡易な構成で容易に脱着可能であると共に、美観よく保持具にしっかり締結される構成の車両用転落防止装置を提供することを目的とするものである。
【０００８】
【問題を解決するための手段】
上記の目的を達成するために請求項１に係る発明は、転落防止部材と該部材を保持する保持具とから構成され、車両連結部の間隙部外側を塞ぐように、それぞれの車両の連結面端部から前記転落防止部材が対向して配設される転落防止装置であって、前記転落防止部材が長い板状の押し出し成形品であり、幅方向断面において、一定厚さの平行部である根元部と、先端に向かって一部または全部の幅が段々細くなり、可撓性を有する先端断面円弧状の細い先端部とを備えており、前記根元部の長さ方向の複数箇所に位置固定用凹部あるいは孔部を設け、前記根元部を挟持する保持具を、前記転落防止部材と同等な長さの一対のＬ型断面形状の板金で構成し、前記保持具のいずれか一方の長さ方向の複数箇所に前記凹部あるいは孔部と係合する複数の突部を設け、前記突部を、円柱状部と先が段々細くなる円錐状部とを備える形状とし、前記凹部あるいは孔部を、前記円柱状部が挿入可能な程度の大きさとしたことを特徴としている。
【０００９】
上記の構成を有する請求項１に係る発明によれば、転落防止部材の幅方向の先端部が撓み易いので、カーブ走行時に接近する連結部の内側において、対向した転落防止部材同士が接触しても破損することはない。また、転落防止部材が対向する車両と接触しても車両を傷付けることもなく、乗降客が接触しても体を傷付けることもない。さらに、保持具が備える複数の円柱状突部を、転落防止部材の平行な根元部の長さ方向の複数箇所に設ける凹部あるいは孔部に係合させて取付位置を固定するので、前記保持具と前記転落防止部材とを容易にまた確実に締結することができる。また、一対のＬ型断面形状の板金製保持具で前記転落防止部材を挟持するので、ネジ等を使用せずに見映えよく堅固に保持することができる。
【００１０】
請求項２に係る発明は、前記転落防止部材の幅方向断面の一方の面を、前記根元部と前記先端部とに至る平らな面としていると共に、前記平行部が、車両間隔に応じた長さに切断容易な平行面部であり、切断した後に前記凹部あるいは孔部を形成容易な平行面部であり、さらに、切断面を有する前記根元部の全長を前記保持具により挟み込んで保持容易な平行面部であることを特徴としている。
【００１１】
上記の構成を有する請求項２に係る発明によれば、根元部分を平行面部として切断容易としたので、種々の車両の連結部の車両間隔に対応した転落防止部材を容易に得ることができる。また、切断した後、平行面部に位置固定用凹部あるいは孔部を形成するので、所定の位置に前記凹部あるいは孔部を正確に形成することができる。さらに、根元部から先端部に至る平らな面を外面側の人目が触れる面とし、切断面を有する根元部の全長を一対の保持具により挟持して被覆するので美観を損なうことがない。
【００１２】
請求項３に係る発明は、前記転落防止部材が板状の弾性体であって、耐候性を有し、さらに着色自在なゴム部材からなることを特徴としている。
【００１３】
上記の構成を有する請求項３に係る発明によれば、太陽光や雨水や洗浄水等に対して劣化せず、さらに、車両に応じた色合いとすることも容易であり美観に優れ、いつまでも色落ちしない所定の色に着色した転落防止部材を得ることができる。
【００２０】
【発明の実施の形態】
以下、本発明に係る鉄道車両連結部の転落防止装置の実施の形態について、図１から図５に基づいて説明する。
【００２１】
図１は本発明に係る転落防止部材の断面図を示す。図２は保持具が転落防止部材を締結したところを示す全体断面図である。図３は一方の保持具の形状を示す断面図である。図４は本発明に係る転落防止装置が鉄道車両に装着されたところを示す斜視図である。図５は転落防止部材の別実施例を示す断面図である。
【００２２】
図４に示すように、転落防止部材１が車両６及び車両７のそれぞれの連結面端部６ａ，７ａに配設されていて、車両連結部の間隙部Ａに乗降客等がホームＰから線路側に転落しないように構成されている。転落防止部材１は長い板状であって、該転落防止部材１と同じ長さの一対のＬ型の保持具２と３とにより締結される構成とした。
【００２３】
車両連結部の間隙部Ａの間隔Ｂは、各電鉄会社や車両の種類によって大きく異なっている。また、間隔Ｂの隙間にどのくらいの幅と長さの転落防止部材１を装着するかも各電鉄会社により一定ではない。そのために、転落防止部材１の幅と長さは種々用意しておく必要がある。
【００２４】
長板状の転落防止部材１は、図１に示すように、その断面形状が矩形の根元部１ａと段々先細になって先丸形状の先端部１ｂとで構成されている。先端１５を先丸（断面円弧状）とし細くしたのは、転落防止部材１の先端部１ｂを撓み易くするためである。先端部１ｂが撓み易い転落防止部材１であると、カーブ状の軌道を走行あるいは停車した際に、対向する転落防止部材同士が接触しても、お互いに撓んで逃げることができ、結果として激しく擦れあうことがない。また、一方の転落防止部材が他方の車両に当接しても車体を傷付けることもない。また、ホーム上の乗降客が誤って落下しそうになって、この転落防止部材１と接触しても、その当たり具合は柔らかくなり人体を傷付けることもない。
【００２５】
転落防止部材１を先細形状とするためには、両面に同様な傾斜を設けて三角錐形状の先端形状としてもよいが、一方の面を平らな面１１とし、他方の面のみを傾斜面１３とするのが好適である。この場合には、平らな面１１が人目に触れる面とし美観が損なわれないように構成することができる。また、人目に触れない後面部は一部が平面部１２であり、先端部のみに傾斜面１３を設けた形状である。
【００２６】
転落防止部材１は押し出し成形品の１枚ものの弾性体部材であって、元々の幅寸法はＬ１である。幅Ｌ１の弾性体部材から幅Ｌ３切断し所定長の幅Ｌ２を得る。この切断作業は矩形の根元部１ａを切断して行うとよい。また該切断作業の際には、平らな面１１を切断装置に載置することで、正確な形状、寸法に切断することができる。
【００２７】
この切断を取付部となる根元部１ａにて行うことで、切断部１４が保持具２，３に隠れることになり人目に触れず外観を損なうことがない。また、撓み易い先細の先端部１ｂはそのままの形状を保っているので、人体と接触した際にはその当たりは柔らかく、同様に人体を傷つけることはない。
【００２８】
図２により、保持具２，３によって転落防止部材１を締結する方法について説明する。保持具２、３は共にＬ型断面形状をした板金であり、その長さは転落防止部材１の長さと同等である。また、いずれか一方の長さ方向の複数箇所に突部４が形成されている。本実施例においては、保持具３に突部４を配設する構成としたが、他方の保持具２に突部４を配設してもよい。
【００２９】
該突部４は転落防止部材１に形成された凹部１ｃに係合するものであり、図３に示すように、円柱状部４ｂと先が段々細くなっている円錐状部４ａとを備えている。先端を円錐状部４ａとしたのは、突部４を凹部１ｃに、確実にまた楽に挿入可能とするためである。
【００３０】
凹部１ｃに突部４が係合することで、転落防止部材１はその取付位置が固定される。この際、転落防止部材１に形成される凹部１ｃは貫通した孔部として形成してもよい。該凹部または孔部１ｃは転落防止部材１の幅を所定の幅Ｌ２とした後に、所定位置に形成されるものである。
【００３１】
転落防止部材１の凹部１ｃに突部４を係合させて保持具２、３を装着し、前記転落防止部材１を挟み込むように装着してネジ５により、車両の連結面端部に固着する構成である。この際、保持具３の断面形状を図３に示すようにその角度αを９０度よりも少し大きく鈍角状に形成し、転落防止部材１を保持具２との協働で挟み込むと、一点鎖線で示した元々の形状３ａが実線で示す直角形状３ｂとなって固定され、保持具３の長さ方向の弾力によって、転落防止部材１をしっかりと保持する構成となる。
【００３２】
特別な固定ネジを使用せずに、保持具２と３とで挟み込むようにして、転落防止部材１を装着する構成としたので、すっきりとした外観を保つことができ美観を損なうことがない。特に平らな面１１を外側に向けて人目に触れる面とすれば、車両間の連結部を体裁よくカバーすることができ好適である。また、転落防止部材１と保持具２，３の色合いを車両と同様な色合いとすることで、さらに体裁のよい外観とすることができる。
【００３３】
図５に別の実施例の転落防止部材１０を示す。人目に触れる面を平らな面１１とし、人目に触れない後面部に平面部１２を設けることは、前記の転落防止部材１と同等であるが、平面部１２から傾斜面１６を経て先端に細い平行面１７を設けて、先丸（断面円弧状）の先端１８とした例である。先端に細い平行部を設けたので、さらに撓み易い形状とすることができる。また、根元部は前記の転落防止部材１と同一であるのでここでは説明しない。
【００３４】
本実施例では保持具を一対のＬ型金具で構成したが、これに限定されるものではなく、転落防止部材１，１０を挟み込む機能を有するものであれば、一体的に形成された保持具を使用してもよい。
【００３５】
転落防止部材１，１０は車両間の連結部に配設されているために、常に外気に接しており、雨に打たれたり、太陽光にさらされている。そのために、色が剥げたり、色落ちしたりする等の劣化をおこすことになる。車両は多くの旅客を輸送する交通手段であって、美観を損ねることは避けることが望ましい。そこで、転落防止部材１の材質に着色性があり、さらに耐候性を有するゴム部材（例えばエチレンプロピレンゴム）を採用することが好適である。
【００３６】
耐候性を有するとは、温湿度や太陽光や雨水等の環境的な影響に対して抵抗力があって、劣化せずまた色落ちしなく、品質が安定していることをいう。
【００３７】
エチレンプロピレンゴムは耐オゾン性、耐薬品性、耐熱性に優れ、さらには太陽光にさらされても色落ちしない性質があるため、転落防止部材１の素材としては好適である。もちろん、同様の性質を備えていれば、その他の素材を用いてもよいのは明らかである。
【００３８】
転落防止部材１を押し出し成形品とし、一部に切断容易な部分を配設した構成としたので、素材を得るのに特別な型材を用意する必要もなく、また、必要寸法に簡単に切断することが可能となり、種々の車両サイズや連結部間隔に対応した転落防止部材１を安価に得ることができる。
【００３９】
車両製造会社または鉄道会社等から所定サイズの転落防止装置の注文がくると、保持具２，３の長さと転落防止部材１の長さと幅が設定されて製造されることになる。把持金具２，３は同一形状の部品を、ただ必要な長さ分切断して得ることができる。また、転落防止部材１は、必要な長さ切断した後に所定の幅出しを行い、最後に凹部１ｃを形成して製造終了となる。
【００４０】
上記のように、あらかじめ初期サイズの保持具２，３と転落防止部材１を準備しておくだけで、種々のサイズの転落防止装置の注文に素早く応じることが可能となり、製造コストを低減できる。また、車両の美観を損ねることがなく、長い間使用しても色落ちしない転落防止装置を得ることができる。
【００４１】
さらには、簡単な構造の転落防止装置としたために、装置の故障等が発生せず、装置寿命が長くなり、さらにコストが低減される効果が得られる。
【００４２】
【発明の効果】
請求項１に記載の発明によれば、車両連結部の間隙部外側を塞ぐように、それぞれの車両の連結面端部から前記転落防止部材が対向して配設される転落防止装置であって、前記転落防止部材が、幅方向断面の一方の面を、平行部である根元部と幅が段々細くなる先端部とに至る平らな面としているので、該平らな面を切断装置に載置して根元部を車両間隔に応じた長さに容易に切断可能であり、部種々の車両タイプや車両サイズにより変化する車両間隔に容易に対応可能な転落防止部材とすることができる。さらに、先端部を可撓性を有する先端断面円弧状としているので、転落防止部材の先端部が撓み易く、カーブ状の軌道を走行あるいは停車した際に、対向する転落防止部材同士が接触してもお互いに撓んで逃げることができ、結果として激しく擦れ合うことがない。また、一方の転落防止部材が他方の車両に当接しても車両を傷付けることもなく、乗降客が接触しても体を傷付けることもない。さらに、一対のＬ型断面形状板金からなる保持具を車両の連結面端部に固定する操作で、前記保持具が備える複数の円柱状突部と転落防止部材に設ける凹部あるいは孔部とを係合させて前記転落防止部材を挟み込んで保持することが可能となるので、ネジ等を使用せずに板状の転落防止部材を堅固に保持することができる。また、前記転落防止部材の根元部の全長を挟持して切断部を被覆する構成となるので、さらに、見映えのよい転落防止装置とすることができる。

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a railroad vehicle connection part falling prevention device according to the present invention will be described with reference to FIGS. 1 to 5.
[0021]
FIG. 1 shows a cross-sectional view of a fall prevention member according to the present invention. FIG. 2 is an overall cross-sectional view showing a place where the holder fastens the fall prevention member. FIG. 3 is a cross-sectional view showing the shape of one of the holders. FIG. 4 is a perspective view showing a fall prevention device according to the present invention mounted on a railway vehicle. FIG. 5 is a sectional view showing another embodiment of the fall prevention member.
[0022]
As shown in FIG. 4, the fall-preventing member 1 is disposed at each of the connecting surface end portions 6 a and 7 a of the vehicle 6 and the vehicle 7, and passengers get on and off from the home P in the gap A of the vehicle connecting portion. It is configured not to fall to the side. The fall prevention member 1 has a long plate shape and is configured to be fastened by a pair of L-shaped holders 2 and 3 having the same length as the fall prevention member 1.
[0023]
The distance B between the gaps A of the vehicle connecting portion varies greatly depending on each electric railway company and the type of vehicle. Also, how much width and length of the fall-preventing member 1 is installed in the gap B is not constant depending on each electric railway company. Therefore, it is necessary to prepare various widths and lengths of the fall prevention member 1.
[0024]
As shown in FIG. 1, the long plate-shaped fall-preventing member 1 is composed of a rectangular root portion 1 a and a tip end portion 1 b that is tapered gradually. The reason why the tip 15 is made thin with a rounded tip (circular arc) is to make the tip 1b of the fall prevention member 1 easier to bend. When the tip 1b is the fall-preventing member 1 that is easy to bend, even when the fall-preventing members that are facing each other come into contact with each other when running or stopped on a curved track, they can bend and escape each other, resulting in intense There is no rubbing. Moreover, even if one fall prevention member contacts the other vehicle, the vehicle body is not damaged. Further, even if passengers on the platform are likely to fall accidentally and come into contact with the fall prevention member 1, the hit state becomes soft and does not hurt the human body.
[0025]
In order to make the fall-preventing member 1 have a tapered shape, it is possible to provide the same inclination on both sides to form a triangular pyramid-shaped tip shape, but one surface is a flat surface 11 and only the other surface is an inclined surface 13. Is preferable. In this case, the flat surface 11 can be configured as a surface that can be seen by the human eye so that the aesthetic appearance is not impaired. In addition, a part of the rear surface portion that is not touched by human eyes is a flat surface portion 12 and has a shape in which an inclined surface 13 is provided only at the tip portion.
[0026]
The fall prevention member 1 is an elastic member of a single extruded product, and the original width dimension is L1. A width L3 is cut from the elastic body member having the width L1 to obtain a predetermined length L2. This cutting operation may be performed by cutting the rectangular root portion 1a. Moreover, in the case of this cutting operation, it can cut | disconnect to an exact shape and a dimension by mounting the flat surface 11 in a cutting device.
[0027]
By performing this cutting at the root portion 1a serving as the attachment portion, the cutting portion 14 is hidden by the holders 2 and 3, and the appearance is not impaired without touching the human eye. Further, since the tapered tip portion 1b that is easily bent maintains the shape as it is, the contact with the human body is soft and does not damage the human body in the same manner.
[0028]
With reference to FIG. 2, a method of fastening the fall prevention member 1 with the holders 2 and 3 will be described. Each of the holders 2 and 3 is a sheet metal having an L-shaped cross section, and the length thereof is equal to the length of the fall prevention member 1. Moreover, the protrusions 4 are formed at a plurality of locations in any one of the length directions. In this embodiment, the protrusion 4 is disposed on the holder 3, but the protrusion 4 may be disposed on the other holder 2.
[0029]
The protrusion 4 engages with a recess 1c formed in the fall prevention member 1, and as shown in FIG. 3, it includes a columnar portion 4b and a conical portion 4a that is gradually tapered. Yes. The reason why the tip is the conical portion 4a is that the protrusion 4 can be reliably and easily inserted into the recess 1c.
[0030]
When the protrusion 4 is engaged with the recess 1c, the mounting position of the fall prevention member 1 is fixed. At this time, the recess 1c formed in the fall prevention member 1 may be formed as a through hole. The recess or hole 1c is formed at a predetermined position after the fall prevention member 1 has a predetermined width L2.
[0031]
The protrusions 4 are engaged with the recesses 1c of the fall prevention member 1 and the holders 2 and 3 are attached. The holders 3 and 3 are attached so as to sandwich the fall prevention member 1 and fixed to the connecting surface end of the vehicle with screws 5. It is a configuration. At this time, when the cross-sectional shape of the holder 3 is formed to be an obtuse angle slightly larger than 90 degrees as shown in FIG. 3 and the fall prevention member 1 is sandwiched in cooperation with the holder 2, The original shape 3 a shown in FIG. 5 is fixed as a right-angled shape 3 b shown by a solid line, and the fall prevention member 1 is firmly held by the elastic force in the length direction of the holder 3.
[0032]
Since the fall prevention member 1 is configured to be sandwiched between the holders 2 and 3 without using a special fixing screw, a clean appearance can be maintained and the aesthetic appearance is not impaired. In particular, if the flat surface 11 is a surface that is exposed to the outside, the connecting portion between the vehicles can be covered with good appearance. In addition, the appearance of the appearance can be further improved by setting the color of the fall prevention member 1 and the holders 2 and 3 to the same color as the vehicle.
[0033]
FIG. 5 shows a fall prevention member 10 of another embodiment. The surface 11 that touches the human eye is the flat surface 11 and the flat surface portion 12 is provided on the rear surface portion that is not touched by the human eye, which is equivalent to the fall prevention member 1 described above. This is an example in which a parallel surface 17 is provided to form a tip 18 having a round tip (circular arc). Since the thin parallel part is provided at the tip, the shape can be further easily bent. Moreover, since the root part is the same as the fall prevention member 1, it will not be described here.
[0034]
In this embodiment, the holder is composed of a pair of L-shaped brackets, but the holder is not limited to this, and the holder is integrally formed as long as it has a function of sandwiching the fall prevention members 1 and 10. May be used.
[0035]
Since the fall prevention members 1 and 10 are disposed at the connecting portion between the vehicles, the fall prevention members 1 and 10 are always in contact with the outside air and are hit by rain or exposed to sunlight. For this reason, deterioration such as color peeling or color fading occurs. Vehicles are a means of transportation that transports many passengers, and it is desirable to avoid detracting from aesthetics. Therefore, it is preferable to employ a rubber member (for example, ethylene propylene rubber) having a coloring property in the material of the fall prevention member 1 and further having weather resistance.
[0036]
Having weather resistance means being resistant to environmental influences such as temperature and humidity, sunlight, rainwater, etc., not being deteriorated or fading, and being stable in quality.
[0037]
Ethylene propylene rubber is suitable as a material for the fall prevention member 1 because it is excellent in ozone resistance, chemical resistance, and heat resistance, and further has a property of not fading even when exposed to sunlight. Of course, other materials may be used as long as they have similar properties.
[0038]
Since the fall prevention member 1 is an extrusion-molded product and a part that can be easily cut is provided, it is not necessary to prepare a special mold material to obtain the material, and it is easily cut to the required dimensions. Therefore, the fall prevention member 1 corresponding to various vehicle sizes and connecting portion intervals can be obtained at low cost.
[0039]
When an order for a fall prevention device of a predetermined size comes from a vehicle manufacturer or a railway company, the length of the holders 2 and 3 and the length and width of the fall prevention member 1 are set and manufactured. The gripping metal fittings 2 and 3 can be obtained by cutting a part having the same shape by a necessary length. Moreover, the fall prevention member 1 performs predetermined width | variety after cut | disconnecting required length, finally forms the recessed part 1c, and is complete | finished manufacture.
[0040]
As described above, simply preparing the initial size holders 2 and 3 and the fall-preventing member 1 makes it possible to quickly respond to orders for various sizes of fall-prevention devices, thereby reducing manufacturing costs. In addition, it is possible to obtain a fall prevention device that does not deteriorate the appearance of the vehicle and does not lose color even when used for a long time.
[0041]
Furthermore, since the fall prevention device has a simple structure, no device failure or the like occurs, the device life is extended, and the cost is further reduced.
[0042]
【The invention's effect】
According to the first aspect of the present invention, there is provided a fall prevention device in which the fall prevention members are arranged to face each other from the end portions of the connection surfaces of the vehicles so as to block the gap outside of the vehicle connection portions. Since the fall prevention member has one surface of the cross section in the width direction as a flat surface extending from the base portion which is a parallel portion to the tip portion where the width is gradually reduced, the flat surface is placed on the cutting device. Thus, the root portion can be easily cut to a length corresponding to the vehicle interval, and the fall preventing member can easily cope with the vehicle interval that changes depending on various vehicle types and vehicle sizes. Furthermore, since the tip portion has a flexible tip cross-section arc shape, the tip portion of the fall prevention member is easily bent, and when the vehicle runs or stops on a curved track, the opposite fall prevention members come into contact with each other. Can bend each other and escape, and as a result, they do not rub hard. Moreover, even if one fall prevention member contacts the other vehicle, the vehicle will not be damaged, and even if a passenger gets in contact, the body will not be damaged. Further, the operation of fixing the holder made of a pair of L-shaped cross-section sheet metal to the end of the connecting surface of the vehicle, the plurality of columnar protrusions provided in the holder and the recesses or holes provided in the fall prevention member. Since the fall prevention member can be sandwiched and held together, the plate-like fall prevention member can be firmly held without using screws or the like. In addition, since the cut portion is covered by sandwiching the entire length of the base portion of the fall prevention member, the fall prevention device can be further improved in appearance .
[0043]
According to the second aspect of the present invention, since the base portion is the parallel surface portion, the cutting operation can be performed accurately and easily, and the fall prevention member corresponding to the connecting portion interval of various vehicles can be easily obtained. Can do. Furthermore, since the recess or hole is formed in the parallel surface portion after cutting, the position fixing recess or hole can be accurately provided at a predetermined arbitrary position. In addition, the flat surface from the root portion to the tip portion is a surface that can be touched by the human eyes on the outer surface side, and the entire length of the root portion having the cut surface can be sandwiched and covered by the holder, so that the appearance is good and sufficient It can be set as the fall prevention apparatus provided with the fall prevention member which can be hold | maintained with intensity | strength .
