しかしながら、特許文献1に記載の転落防止装置においては、常に荷台に立てたまま設置されているため、貨物の積込みや荷下ろしの際に、クレーン作業の障害となり、効率が悪いことがあった。
また、貨物の積込みや荷下ろしを行う作業場が狭かったり、天井が低かったり、貨物車の走行中は、各支柱を取り外す必要があり、作業が繁雑であった。
従って、本発明は上述の問題点に鑑みてなされたものであり、その目的は、貨物の積込みや荷下ろしの際でも、クレーン作業の障害とならず、作業効率を向上させる転落防止装置を提供することにある。
However, since the fall prevention device described in Patent Document 1 is always installed while standing on the loading platform, when loading and unloading cargo, the crane operation becomes an obstacle and sometimes the efficiency is poor.
In addition, the work space for loading and unloading cargo was narrow, the ceiling was low, and each column had to be removed while the freight car was running, making the work complicated.
Accordingly, the present invention has been made in view of the above-described problems, and its object is to provide a fall prevention device that does not become an obstacle to crane work even when cargo is loaded or unloaded, and that improves work efficiency. There is to do.

上記問題を解決するため、本発明の請求項1に係る転落防止装置は、円筒形状の嵌入部がヒンジ部によって連結された長尺状の本体部と、貨物車の荷台に形成された孔部に嵌合し、前記嵌入部を摺動可能かつ回動可能に収容する基部と、複数の前記本体部間を張架するネットとを有してなり、前記基部に少なくとも前記ヒンジ部及び前記本体部の前記ヒンジ部側の一端部を収容して前記本体部を前記荷台に対して立設させると共に、前記基部内で前記嵌入部を摺動させて前記ヒンジ部及び前記本体部の前記ヒンジ部側の一端部を露出させて前記荷台に対して前記本体部を折り曲げ可能としたことを特徴としている。
また、本発明の請求項2に係る転落防止装置は、請求項1に記載の転落防止装置において、前記本体部が、ヒンジ部によって連結された第1の本体部と第2の本体部とからなることを特徴としている。
In order to solve the above-described problem, the fall prevention device according to claim 1 of the present invention includes a long body portion in which a cylindrical insertion portion is connected by a hinge portion, and a hole portion formed in a loading platform of a freight vehicle. And a base portion that slidably and rotatably accommodates the insertion portion, and a net that stretches between the plurality of main body portions, and at least the hinge portion and the main body on the base portion The one end part of the hinge part side is accommodated and the main body part is erected with respect to the loading platform, and the fitting part is slid within the base part to slide the fitting part and the hinge part of the main body part It is characterized in that the main body can be bent with respect to the loading platform by exposing one end of the side.
A fall prevention device according to claim 2 of the present invention is the fall prevention device according to claim 1, wherein the main body portion includes a first main body portion and a second main body portion connected by a hinge portion. It is characterized by becoming.

本発明の請求項1に係る転落防止装置によれば、貨物車の荷台に形成された孔部に嵌合させた基部からヒンジ部を露出させるだけで、本体部を前記荷台に対して屈曲させることができるので、貨物の積込みや荷下ろしの際でも、クレーン作業の障害とならない。また、ネットを張ったままで各本体部を屈曲させることができるので、そのまま貨物車を走行させることができるので、転落防止装置を荷台から取り外すような作業を行う必要がない。これは、結果として、貨物の積込みや荷下ろしの際の作業効率を向上させることに繋がる。   According to the fall prevention device of the first aspect of the present invention, the main body is bent with respect to the loading platform only by exposing the hinge from the base fitted in the hole formed in the loading platform of the freight vehicle. Therefore, even when loading and unloading cargo, it does not become an obstacle to crane work. In addition, since each main body can be bent while the net is stretched, the freight vehicle can be run as it is, so there is no need to perform an operation of removing the fall prevention device from the loading platform. As a result, this leads to an improvement in work efficiency when loading and unloading cargo.

また、転落防止装置にネットを張ったままで各本体部を荷台の外側に屈曲させることで、万が一、作業者が荷台から落下しても、荷台の外側に展開された転落防止装置に張られたネットによって受け止めることができ、作業者の安全対策を向上することができる。

(First embodiment)
Hereinafter, a first embodiment of a fall prevention device according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a first embodiment of a fall prevention device according to the present invention, where (a) is a front view, (b) is a plan view, (c) is a side view, and (d) is a side view. It is a side view which shows a state when a main-body part is bent.
As shown in FIG. 1A, the fall prevention device 1 includes a main body portion 10, an insertion portion 20 connected to the main body portion 10 by a hinge portion 60, and a hole portion 101 formed in a loading platform 100 of a freight vehicle. And a base 30 that slidably and rotatably accommodates the insertion portion 20, and a net (not shown) that stretches between the plurality of main body portions 10 and 10. Below, the main-body part 10, the insertion part 20, the base 30, and the hinge part 60 are demonstrated, and a net | network is mentioned later.

<本体部>
本体部10は、長尺形状をなし、側面には複数のアイボルト40が長手方向(軸方向)に列設されている(図1(b)参照)。本体部10の長手方向の一端面には、ヒンジ部60を構成するヒンジ片11が形成されている。アイボルト40は、複数の本体部10,10間にネットを張架するために、当該ネットを固定する部材である。
<Main body>
The main body 10 has an elongated shape, and a plurality of eyebolts 40 are arranged in the longitudinal direction (axial direction) on the side surface (see FIG. 1B). A hinge piece 11 constituting the hinge portion 60 is formed on one end surface of the main body portion 10 in the longitudinal direction. The eyebolt 40 is a member that fixes the net in order to stretch the net between the plurality of main body portions 10 and 10.

<嵌入部>
嵌入部20は、円筒形状をなし、一端面に突出したヒンジ片21が形成されている。このヒンジ片21に形成された孔21aと、本体部10のヒンジ片11に形成された孔11aとに軸体50が嵌合することによって、嵌入部20に対して本体部10が一方向に屈曲するヒンジ部(ヒンジ機構)を備えることとなる。ここで、嵌入部20の形状は、基部30に収容された状態で、嵌入部20の軸方向を中心に回動可能である形状であれば特に制限はなく、目的に応じて適宜選択することができる。すなわち、嵌入部20の形状は、中空の円筒形状に限られず、円柱形状でもよい。また、嵌入部20の形状は、矩形管形状や角柱形状でもよい。
<Insertion part>
The insertion portion 20 has a cylindrical shape, and a hinge piece 21 protruding from one end surface is formed. When the shaft body 50 is fitted into the hole 21 a formed in the hinge piece 21 and the hole 11 a formed in the hinge piece 11 of the main body 10, the main body 10 is unidirectional with respect to the fitting part 20. A bent hinge part (hinge mechanism) is provided. Here, the shape of the insertion portion 20 is not particularly limited as long as it is a shape that can be rotated around the axial direction of the insertion portion 20 in the state of being accommodated in the base portion 30, and is appropriately selected according to the purpose. Can do. That is, the shape of the insertion portion 20 is not limited to a hollow cylindrical shape, and may be a columnar shape. Further, the shape of the insertion portion 20 may be a rectangular tube shape or a prismatic shape.

<基部>
基部30は、矩形管形状をなし、その内周面において嵌入部20をその軸方向に摺動可能かつ前記軸方向に回動可能に収容する。すなわち、嵌入部20は、ヒンジ片21の突出方向と直交する平面で回動可能に基部30に収容されている。また、嵌入部20は、基部30に対する回動軸に沿って摺動可能に基部30に収容されている。
また、基部30は、貨物車の荷台100に形成された孔部101に嵌合する。
<Base>
The base portion 30 has a rectangular tube shape, and accommodates the insertion portion 20 on its inner peripheral surface so as to be slidable in the axial direction and rotatable in the axial direction. That is, the fitting part 20 is accommodated in the base part 30 so as to be rotatable on a plane orthogonal to the protruding direction of the hinge piece 21. Further, the insertion portion 20 is accommodated in the base portion 30 so as to be slidable along a rotation axis with respect to the base portion 30.
The base 30 is fitted into a hole 101 formed in the cargo bed 100 of the freight vehicle.

このように構成された転落防止装置1は、図1(c)に示すように、貨物車の荷台100に形成された孔部101に立てて設置される際には、嵌入部20だけでなく、ヒンジ部60を収容した基部30が孔部101内に嵌合されることによって固定される。すなわち、基部30は、孔部101の深さ寸法に応じて、孔部101に嵌合させたときに、基部30の上端部が孔部101の開口面(荷台100の表面)と面一になり、かつヒンジ部60と嵌入部20とが基部30に収容されるように設定される。このとき、ヒンジ部60だけでなく、本体部10の一端部(ヒンジ部60側)12も基部30に収容される。嵌入部20と共に少なくともヒンジ部60が基部30に収容されることで、ヒンジ部60が機能しなくなり、転落防止装置1は、従来の支柱(スタンション)と同様に孔部101に立てて設置されることとなる。
ここで、本体部10の一端部12は、ヒンジ片が設けられた本体部10の端面から所定の寸法の部分を指す。この「所定の寸法」は、孔部101の形状や、本体部10の長さ及び重量などに応じて、少なくとも孔部101に本体部10が安定して立設される寸法が設定される。
When the fall prevention device 1 configured in this way is installed upright in the hole 101 formed in the cargo bed 100 of the freight car as shown in FIG. The base 30 accommodating the hinge part 60 is fixed by being fitted into the hole 101. That is, when the base 30 is fitted into the hole 101 according to the depth dimension of the hole 101, the upper end of the base 30 is flush with the opening surface of the hole 101 (the surface of the loading platform 100). And the hinge part 60 and the fitting part 20 are set to be accommodated in the base part 30. At this time, not only the hinge part 60 but also the one end part (on the hinge part 60 side) 12 of the main body part 10 is accommodated in the base part 30. Since at least the hinge portion 60 is accommodated in the base portion 30 together with the fitting portion 20, the hinge portion 60 does not function, and the fall prevention device 1 is installed upright in the hole portion 101 in the same manner as a conventional support (stanchion). It will be.
Here, the one end portion 12 of the main body portion 10 indicates a portion having a predetermined dimension from the end surface of the main body portion 10 provided with the hinge piece. The “predetermined dimension” is set to a dimension at which the main body 10 is stably erected at least in the hole 101 according to the shape of the hole 101, the length and weight of the main body 10, and the like.

一方、作業場等において貨物の積込みや荷下ろしを行う場合には、図1(d)に示すように、本体部10を基部30から引き揚げ、荷台100の表面(基部30の上端面)からヒンジ部60及び本体部10の一端部(ヒンジ部60側)12を露出させる。このようにすることで、ヒンジ部60を機能させることを可能とし、基部30に対して回動可能とされた嵌入部20を介して本体部10を荷台100と平行な面上で90°回動させて荷台100の外側に折り曲げる。なお、図1(d)では、本体部10を荷台100の外側に折り曲げたが、本体部10を貨物車の走行方向に折り曲げてもよい。このようにすることで、荷台100に転落防止装置1を設置したまま貨物車を走行させることができ、貨物車の走行に際して転落防止装置1を逐一取り外す面倒がなく、作業上の安全性も確保できる。   On the other hand, when loading and unloading cargo at a work place or the like, as shown in FIG. 1 (d), the main body 10 is lifted from the base 30 and hinged from the surface of the loading platform 100 (the upper end surface of the base 30). 60 and one end part (on the hinge part 60 side) 12 of the main body part 10 are exposed. In this way, the hinge portion 60 can be made to function, and the main body portion 10 is rotated 90 ° on a plane parallel to the loading platform 100 via the insertion portion 20 that is rotatable with respect to the base portion 30. It is moved and bent outside the loading platform 100. In addition, in FIG.1 (d), although the main-body part 10 was bent outside the loading platform 100, you may bend the main-body part 10 in the running direction of a freight vehicle. By doing so, the freight vehicle can be run with the fall prevention device 1 installed on the loading platform 100, and there is no hassle to remove the fall prevention device 1 one by one during the running of the freight vehicle, thus ensuring work safety. it can.
