Further, as shown in FIG. 6, the front leg portion 17 and the rear leg portion 18 are set to such a length that the vertical column 13 is positioned higher than the car-mounted device 2 when the left and right handrail portions 11, 12 are lying down. ing.
次に、前記従来のかご上手摺装置１０の動作について説明する。保守点検作業時に、かご上手摺装置１０を起立状態に保持している場合には、図８（ａ）に示すように、上段ピン３５がＵ字穴３３に挿入されているため、縦柱１３は起立状態にある。また、前脚部１７の脚部材２０は、図７に示すように、縦柱１３に沿って下垂している。 Next, the operation of the conventional car handrail device 10 will be described. When the car upper handrail device 10 is held upright during the maintenance and inspection work, the upper pin 35 is inserted into the U-shaped hole 33 as shown in FIG. Is upright. Moreover, the leg member 20 of the front leg part 17 hangs down along the vertical column 13, as shown in FIG.
保守点検作業が終了して、かご上手摺装置１０を倒伏するときは、図８（ｂ）に示すように、右手摺部１１の縦柱１３を持ち上げてＵ字穴３３から上段ピン３５を抜き、図８（ｃ）に示すように、縦柱１３を下段ピン３４を中心にして、図８の反時計方向に回転し、図８（ｄ）に示すように、縦柱１３を９０度傾倒する。 When the car handrail device 10 is laid down after the maintenance and inspection work is completed, the vertical column 13 of the right handrail portion 11 is lifted and the upper pin 35 is removed from the U-shaped hole 33 as shown in FIG. 8 (c), the vertical column 13 is rotated counterclockwise in FIG. 8 around the lower pin 34, and the vertical column 13 is tilted 90 degrees as shown in FIG. 8 (d). To do.
これによって、前脚部１７の脚部材２０の先端面２０ａは、図６に示すように、自重によって縦柱１３から離れ、縦柱１３と脚部材２０が直交した状態で、先端面２０ａがかご１の上面に当接する。このとき、脚部材２０の先端部は座金２４に係止されるため、脚部材２０の先端部が嵩上台３０方向に動くことはなく、安定した状態で保持される。これにより、右手摺部１１は、嵩上台３０，前脚部１７及び後脚部１８によってかご１上に倒伏状態に収納される。また、左手摺部１２も同様に行なう。
尚、保守点検作業時には、上記と逆の手順によって、かご上手摺装置１０を起立状態にする。
Thereby, as shown in FIG. 6, the front end surface 20 a of the leg member 20 of the front leg portion 17 is separated from the vertical column 13 by its own weight, and the front end surface 20 a is in a state where the vertical column 13 and the leg member 20 are orthogonal to each other. It abuts on the upper surface. At this time, since the distal end portion of the leg member 20 is locked to the washer 24, the distal end portion of the leg member 20 does not move in the direction of the bulkhead 30 and is held in a stable state. As a result, the right handrail portion 11 is housed in a lying state on the car 1 by the bulkhead 30, the front leg portion 17 and the rear leg portion 18. Moreover, the left handrail part 12 is performed similarly.
At the time of maintenance / inspection work, the car upper handrail device 10 is raised in the reverse procedure.
しかしながら、前記従来のかご上手摺装置１０は、右手摺部１１及び左手摺部１２を安定して倒伏状態に保持するために、かご１に座金２４を設けなければならないという問題があった。 However, the conventional car handrail device 10 has a problem that the car 1 must be provided with a washer 24 in order to stably hold the right handrail part 11 and the left handrail part 12 in a lying state.

The upper surface of the car is provided with a bulkhead that rotatably supports the vertical column and supports the vertical column so that the vertical column can be moved up and down by a predetermined distance. It is pivotally attached to the vertical column, and a tip end surface is provided on the other end side, and when the handrail portion is in a lying state, one end side of the leg portion on the horizontal projection plane is more than the other end side. It is configured to come to the bulkhead side.
また本発明は、前記縦柱に対する前記脚部の回転量を制限するためのストッパが前記脚部に設けられていることを特徴とするものである。
更に本発明は、前記脚部の先端面は、倒伏状態において、前記かご上面と平行になる構成であることを特徴とするものである。
Further, the invention is characterized in that a stopper for limiting the amount of rotation of the leg with respect to the vertical column is provided on the leg.
Furthermore, the present invention is characterized in that the front end surface of the leg portion is configured to be parallel to the upper surface of the car in the lying down state.
また本発明は、前記嵩上台は断面が前記縦柱の下部を囲う形状をなすとともに、その中に前記縦柱の下部を収容可能であり、前記縦柱の回動面と直交方向の一対の側面には、それぞれ長手が上下方向の長穴が設けられており、前記縦柱には前記長穴に挿入されるピンが設けられ、前記ピンが前記長穴内を昇降及び回動することによって、前記縦柱が前記嵩上台に対して昇降及び回動可能に構成されており、前記嵩上台の側面のうち、前記縦柱の下端が回動する側の側面には、前記縦柱の回動時に、前記縦柱の下端が干渉しないための空間を有していることを特徴とするものである。 According to the present invention, the bulkhead has a shape in which a cross section surrounds a lower portion of the vertical column, and a lower portion of the vertical column can be accommodated therein, and a pair of orthogonal directions with respect to a rotation surface of the vertical column Each side surface is provided with a long hole whose longitudinal direction is the vertical direction, and the vertical column is provided with a pin inserted into the long hole, and the pin moves up and down and rotates in the long hole, The vertical column is configured to be able to move up and down with respect to the bulkhead, and among the side surfaces of the bulkhead, on the side surface on which the lower end of the vertical column rotates, the vertical column rotates. Sometimes, the vertical column has a space for preventing the lower end from interfering.
本発明によれば、かごに座金を設けなくても、かご上手摺装置を安定して倒伏状態に保持することができる。 According to the present invention, the car handrail device can be stably held in a lying state without providing a washer on the car.
本発明の実施の形態について図により説明する。図１は本実施の形態によるかご上手摺装置の右手摺部を示すものであり、図６の右上部に相当する図である。図２はかご上手摺装置の縦柱の傾倒動作の説明図で図８に相当する図、図３は図２（ａ）のＡ−Ａ断面図である。 Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a right handrail portion of the car upper handrail device according to the present embodiment, and corresponds to the upper right portion of FIG. FIG. 2 is an explanatory view of the vertical column tilting operation of the car handrail device and corresponds to FIG. 8, and FIG. 3 is a cross-sectional view taken along line AA of FIG.
図において、４０は右手摺部、４１は縦柱、４２は上手摺あり、それぞれ角パイプからなっている。また、下手摺や補強部材は図４の従来技術と変わりはない。
４３は縦柱４１の中間部のやや先端側に、ピン４４によって枢着された前脚部で、断面コ字状をなしている。このコ字状の開口と反対側の反開口側面４５の上部には、反開口側面４５の上端部を切り欠いたストッパ４６が形成されている。このストッパ４６は前脚部４３がピン４４を中心にして、図１の時計方向に回転できる量を制限するものである。
In the figure, 40 is a right handrail portion, 41 is a vertical column, and 42 is an upper handrail, each of which is made of a square pipe. Further, the lower handrail and the reinforcing member are the same as those in the prior art of FIG.
Reference numeral 43 denotes a front leg portion pivotally attached by a pin 44 to a slightly distal end side of the intermediate portion of the vertical column 41 and has a U-shaped cross section. A stopper 46 in which the upper end portion of the anti-opening side surface 45 is notched is formed on the upper side of the anti-opening side surface 45 opposite to the U-shaped opening. The stopper 46 limits the amount that the front leg 43 can rotate in the clockwise direction in FIG.
前脚部４３の先端面４７は、前脚部４３の長手方向に対して傾斜しており、反開口側面４５と先端面４７のなす角度αは鋭角になっている。
また、図１に示すように、前脚部４３は、右手摺部４０の倒伏時に縦柱４１がかご上機器２よりも高い位置になるような長さに設定されている。
The front end surface 47 of the front leg portion 43 is inclined with respect to the longitudinal direction of the front leg portion 43, and the angle α formed between the non-opening side surface 45 and the front end surface 47 is an acute angle.
Further, as shown in FIG. 1, the front leg portion 43 is set to a length such that the vertical column 41 is positioned higher than the car-mounted device 2 when the right handrail portion 40 is lying down.
５０は嵩上台であり、断面コ字状の本体５１を有し、この本体５１の開口側５１ａには、その上端がかご上機器２よりも高くなるようにプレート５２が取り付けられている。開口側５１ａは、前記の連結金具３１と同様に、図６における中央側を向いており、左右の手摺部の開口側が互いに対向するように配置されている。 Reference numeral 50 denotes a bulkhead, which has a main body 51 having a U-shaped cross section. A plate 52 is attached to the opening side 51 a of the main body 51 so that the upper end of the main body 51 is higher than that of the car-mounted device 2. The opening side 51a faces the center side in FIG. 6 similarly to the connection fitting 31, and is arranged so that the opening sides of the left and right handrail portions face each other.
また、開口側５１ａの反対側には、プレート５２の高さ位置付近から所定距離だけ上方まで空間５３が開けられている。この空間５３は図２（ｂ）に示すように、縦柱４１が回転するときに、縦柱４１の下端部が本体５１に干渉しないためのものである。 Further, on the opposite side of the opening side 51a, a space 53 is opened from the vicinity of the height position of the plate 52 up to a predetermined distance. As shown in FIG. 2B, the space 53 is for preventing the lower end portion of the vertical column 41 from interfering with the main body 51 when the vertical column 41 rotates.
５４は本体５１の開口側５１ａと直交する面に設けられた一対の長穴、５５は縦柱４１に設けられて長穴５４に挿入されたピンである。５６はプレート５２に設けられたストッパであり、図２（ａ）に示すように、縦柱４１が起立状態にあるときに、縦柱４１の下端部を支持するものである。 Reference numeral 54 denotes a pair of long holes provided in a surface orthogonal to the opening side 51 a of the main body 51, and 55 denotes a pin provided in the vertical column 41 and inserted into the long hole 54. Reference numeral 56 denotes a stopper provided on the plate 52, which supports the lower end of the vertical column 41 when the vertical column 41 is in an upright state as shown in FIG.
次に、本実施の形態の動作について説明する。保守点検作業時に、右手摺部４０を起立状態に保持している場合には、図２（ａ）に示すように、縦柱４１がストッパ５６に支持されて起立状態にある。また前脚部４３は、図１に示すように、縦柱４１に沿って下垂している。 Next, the operation of the present embodiment will be described. When the right handrail portion 40 is held in the standing state during the maintenance and inspection work, the vertical column 41 is supported by the stopper 56 and is in the standing state as shown in FIG. Moreover, the front leg part 43 hangs down along the vertical column 41, as shown in FIG.
保守点検作業が終了して、右手摺部４０を倒伏するときは、図２（ｂ）に示すように、縦柱４１を持ち上げてピン５５を中心にして、図２の反時計方向に回転し、図２（ｃ）に示すように、縦柱４１を９０度傾倒する。 When the right handrail portion 40 is laid down after the maintenance and inspection work is completed, as shown in FIG. 2B, the vertical column 41 is lifted and rotated counterclockwise in FIG. As shown in FIG. 2C, the vertical column 41 is tilted 90 degrees.
これによって、前脚部４３の先端面４７は、図１に示すように、自重によって縦柱４１から離れ、かご１の上面に当接する。
そして、ピン４４を中心にして、ストッパ４６が縦柱４１に当たるまで、前脚部４３を、図１の時計方向に動かしてやると、縦柱４１と前脚部４３の反開口側面４５とが鋭角αをなす状態で、先端面４７がかご１の上面に当接する。
即ち、縦柱４１の先端側（図１の左方）と前脚部４３の長手方向とのなす角度αが鋭角になる。
As a result, the front end surface 47 of the front leg portion 43 is separated from the vertical column 41 by its own weight and abuts against the upper surface of the car 1 as shown in FIG.
When the front leg 43 is moved in the clockwise direction in FIG. 1 until the stopper 46 hits the vertical column 41 with the pin 44 as the center, the vertical column 41 and the anti-opening side surface 45 of the front leg 43 have an acute angle α. In this state, the tip surface 47 comes into contact with the upper surface of the car 1.
That is, the angle α formed between the front end side of the vertical column 41 (left side in FIG. 1) and the longitudinal direction of the front leg portion 43 is an acute angle.
別の視点から見ると、前脚部４３の長手方向とかご１上面の嵩上台５０方向とのなす角度が鋭角αとなる。したがって、先端面４７は嵩上台５０方向に動くことはなく、右手摺部４０は安定した状態で保持される。
換言すれば、水平投影面上で、前脚部４３の一端側（ピン４４側）が他端側（先端面４７側）よりも嵩上台５０側にくるため、右手摺部４０は安定した状態で保持される。
From another viewpoint, the angle formed by the longitudinal direction of the front leg 43 and the direction of the bulkhead 50 on the upper surface of the car 1 is an acute angle α. Therefore, the tip surface 47 does not move in the direction of the bulkhead 50, and the right handrail portion 40 is held in a stable state.
In other words, on the horizontal projection plane, one end side (pin 44 side) of the front leg portion 43 is closer to the raised platform 50 side than the other end side (tip end surface 47 side), so the right handrail portion 40 is in a stable state. Retained.
また、保守点検作業時には、上記と逆の手順によって、右手摺部４０を起立状態にする。
尚、右手摺部４０の後脚部については、前脚部４３と同様に、縦柱４１に枢着してもよいし、また従来の後脚部１８のように、縦柱４１に固定してもよい。更に、前脚部４３の縦柱４１への取付位置は、中間部のやや先端側に限ることはなく、縦柱４１の上端部など他の箇所でもよい。
Moreover, at the time of a maintenance inspection work, the right handrail part 40 is made to stand in the reverse procedure.
Note that the rear leg portion of the right handrail portion 40 may be pivotally attached to the vertical column 41 as in the case of the front leg portion 43, or may be fixed to the vertical column 41 like the conventional rear leg portion 18. Also good. Furthermore, the attachment position of the front leg portion 43 to the vertical column 41 is not limited to the slightly distal end side of the intermediate portion, and may be another location such as the upper end portion of the vertical column 41.
これにより、従来のようにかご１に座金２４を設けなくても、右手摺部４０を安定した状態で保持することができる。
尚、図１〜図３では右手摺部４０について説明しているが、左手摺部も左右対称になるだけで、同じ動作を行なう。
Thereby, even if it does not provide the washer 24 in the cage | basket | car 1 conventionally, the right handrail part 40 can be hold | maintained in the stable state.
1 to 3, the right handrail portion 40 is described, but the left handrail portion is also left-right symmetrical and performs the same operation.
更に本実施の形態は、図３に示すように、本体５１及びプレート５２と縦柱４１との隙間が少ないので、図２（ａ）に示す縦柱４１の起立時に、縦柱４１の起立状態が安定するという利点がある。
これに対して従来装置は、図９に示すように、連結金具３１の開口側３１ａの反対側の面と縦柱１３との隙間が大きいため、保守点検作業中に縦柱１３が安定しにくい可能性がある。更に、図８（ｂ）に示すように、何かの拍子に縦柱１３が持ち上がって上段ピン３５がＵ字穴３３から外れると、縦柱１３が大きく傾く虞もある。
上記のように、本実施の形態は縦柱４１の起立時の安定性の面でも優れている。
Further, as shown in FIG. 3, the present embodiment has a small gap between the main body 51 and the plate 52 and the vertical column 41. Therefore, when the vertical column 41 shown in FIG. Has the advantage of being stable.
On the other hand, in the conventional apparatus, as shown in FIG. 9, since the gap between the surface opposite to the opening side 31 a of the connection fitting 31 and the vertical column 13 is large, the vertical column 13 is difficult to be stabilized during the maintenance inspection work. there is a possibility. Furthermore, as shown in FIG. 8B, if the vertical column 13 is lifted up in any time and the upper pin 35 is removed from the U-shaped hole 33, the vertical column 13 may be greatly inclined.
As described above, this embodiment is also excellent in terms of stability when the vertical column 41 stands.
前記の実施の形態では、ストッパ５６をプレート５２に設けているが、本体５１側に設けてもよい。またプレート５２と本体５１を一体構造としてもよい。
更に、ストッパ５６を省略することもできる。この場合、縦柱４１の起立時には、ピン５５が長穴５４の底部に当接して縦柱４１を支持することになる。更にまた、ストッパ５６を省略する場合、長穴５４を更に下方に伸ばして、かご１で縦柱４１を直接支持することも可能である。
また、縦柱４１や嵩上台５０などの形状は、断面角パイプ状に限定されるものではない。
In the above embodiment, the stopper 56 is provided on the plate 52, but it may be provided on the main body 51 side. The plate 52 and the main body 51 may be integrated.
Further, the stopper 56 can be omitted. In this case, when the vertical column 41 stands, the pin 55 contacts the bottom of the elongated hole 54 to support the vertical column 41. Furthermore, when the stopper 56 is omitted, it is possible to extend the elongated hole 54 further downward and directly support the vertical column 41 with the car 1.
Moreover, the shapes of the vertical column 41 and the bulkhead 50 are not limited to the shape of a cross-section square pipe.
