【発明の属する技術分野】
本発明は、エスカレーター装置に係り、特にその踏段往復路の走行配列と半転機構の構成に関する。
【０００２】
【従来の技術】
一般に、エスカレーター装置は、上下の両乗降床間の往路においては踏板表面が上向きの水平面を形成し、反対にその復路においては踏板表面が傾斜部に沿って下向きの傾斜面を形成して走行する反転式往復路の構成（例えば実公平４− ５５０１６ 号公報）となっている。また、踏段の往路においては上記と同様踏板表面が上向きの水平面を形成するのに対し、復路においても踏板表面が上向きになって、エスカレーターの設置角度に沿う傾斜路を形成しつつ走行する平行半転式往復路の構成（例えば特開平１−２４２３８９ 号公報）も提案されている。
【０００３】
【発明が解決しようとする課題】
上記公知例の前者は、最も一般的な踏段走行系であるが、この踏段の往復路を合計した上下寸法が大きく、エスカレーター装置の全体姿（特に機械胴部の高さ）が大型化して建築空間を占有するスペース過多の問題があった。このため、公知例の後者のように機械胴部高さの縮減を意図した薄型エスカレーターの提案がなされたものであるが、これらの公知例は共通的にエスカレーター装置内部、特に往路側の踏段を取外して機械装置の保守点検を行うに際しての保守員の安全確保，作業効率の向上に対する配慮が皆無であり、これらの面での改善が望まれていた。すなわち、公知例の前者は、往路側の踏段を取外して保守員が機械内部の点検や改修作業を行う際、その足場は踏段の裏側の凹凸な構造物、特に多数の蹴上げ板の存在が保守員の安定姿勢保持や歩行の妨げとなって危険を強いる障害物となっていた。この障害を解決するため、往路の踏段を取外した状態において復路の凹凸を平坦化して安全作業に対処する足場装置（特開平１０−２７９２５１号公報）を装着する例もあるが、この方法は作業効率の著しい悪化とその装置の運搬、あるいは収納（保管）スペースを要するという歓迎されざる欠点を有していた。さらに、公知例の後者は、踏段が復路において平坦上になっていて踏段往復路の機械胴部高さが小さい薄型エスカレーターが実現できる一方、作業足場としての上記のような凹凸障害は解消されるものの、踏板が形成する傾斜面が滑りやすく保守員の滑落事故を招くという安全上重大な問題が抱えていた。
【０００４】
本発明の目的は、枠体に収納される機械内部の保守点検を行う際、安定的な作業足場を形成して作業の安全と効率化に寄与し得る踏段復路の構成を備えた薄型のエスカレーター装置を提供することにある。
【０００５】
【課題を解決するための手段】
本発明は、上記目的を達成するために、一方の乗降床と他方の乗降床に連なる水平部と、この両水平部の間を連結する傾斜部を有する長尺の枠体と、この枠体の長手方向に無端状に連結され、踏板と蹴上げ板とで略三角形に形成されて案内レール上を走行する踏段と、両水平部の中に収納されて踏段を往路から復路、あるいは復路から往路にかけて平行半転駆動させる駆動歯車を備えたものにおいて、前記踏段を、その往路においては踏段表面を上向きの水平面とした踏段状に、またその復路においても踏板表面を上向きの略水平面とした階段状に走行させる往復路構成とし、かつ前記駆動歯車近傍に往路から復路、あるいは復路から往路にかけて前記踏段を平行半転させる踏段半転補助機を設け、この踏段半転補助機構は、前記踏段の蹴上げ板に接触して回転力により前記踏段を半転させる回転体で構成されるようにしたものである。
【０００６】
上記構成は、踏段の復路においてその踏板が略水平面を確保し、往路と同様整然とした多数の階段を形成するので、往路の踏段を取外しての機械内部の保守点検を行うに際し、復路の踏段上に位置する保守員の姿勢が安定し、安全性と作業効率の向上に有効で、かつ薄型のエスカレーター装置を提供することができる。
【０００７】
【発明の実施の形態】
以下、本発明の一実施の形態を図１〜図３に沿って説明する。図１は、エスカレーター装置１の通常状態の全体側面図、図２は、図１のエスカレーター装置１の保守点検作業状態を示す全体側面図、図３は、図１および図２の要部の内部構造を示す側面図である。このエスカレーター装置１は、下部側にある一方の乗降床２と上部側にある他方の乗降床３の間に跨る水平部４Ａ，水平部４Ｂおよび傾斜部４Ｃを有する長尺の枠体４と、この枠体４の長手方向に無端状に連結され、乗客が乗る水平面を持つ踏板５ａとその後面を塞ぐ蹴上げ板５ｂとで略三角形に形成されて案内レール上を走行する踏段５が両水平部４Ａ，４Ｂの中で往路Ｍから復路Ｎ、あるいは復路Ｎから往路Ｍへと図３に示すように半円分だけ平行状態で転向走行しつつ往路Ｍ区間で乗客輸送を行う仕組みになっている。そして、踏段５の配列は、このエスカレーター装置１内に点在する各種安全装置，配線接続部，ハンドレール駆動系（いずれも図示省略）などを保守点検する際、往路Ｍ側の踏段５を取外した場合、図２に示すようにその復路Ｎの踏段５も乗客が乗る踏板５ａが水平もしくは多少傾斜した略水平面を形成し、この略水平な踏板５ａの上で保守員Ｈが作業できる構成となっている。
【０００８】
ここで、上記踏段５の配列構成による踏段５の走行（移動）は、図１および図２に示したように踏段５を無端状に連結する踏段チューン６と一対の踏段ローラ５ｃ，５ｄを載せて走行させる案内レール（図示省略）の構成と図３に示す半転駆動構成により実用可能となる。このことを両水平部４Ａと４Ｂの内部構成のうち、下部側の例について説明すれば、踏段チューン６を巻きかけてこの踏段チューン６と踏段５を平行半転駆動させる駆動歯車７の所で、図１と図２で図示を省略した案内レールの末端レール８と９に沿って踏段５を平行半転させる踏段半転補助機構１０によって、例えば往路Ｍにおいて矢印ｍのように上昇、復路Ｎにおいて矢印ｎのように下降する踏段５は、復路Ｎ側の末端レール８の半転軌跡である曲線部８Ａの開口部１１を通過して往路Ｍ側の末端レール９の曲線部９Ａに移行する際、踏段５に接触し、この踏段５の半転軌跡に沿って回転する回転力で踏段５が押上げられることにより達成される。ここで、踏段半転補助機構１０は、一対の駆動輪１０Ａにより矢印Ｐ側の回転力を与えられ、案内ローラ１０Ｂにより案内されながら踏段５の半転軌跡に沿って回転する回転体１０Ｃが踏段５の蹴上げ板５ｂに接触しつつ踏段５の走行速度と同期して常に同速度で回転しているもので、この回転体１０Ｃと蹴上げ板５ｂの摩擦力をもって踏段５を押上げ、案内レールの末端レール８から９へ、すなわち復路Ｎから往路Ｍへと平行半転されて往路Ｍ，復路Ｎともに踏段５の踏板５ａを上向き走行可能な踏段配列としている。この構成は、踏段５が矢印ｍ，ｎと反対側の回転、即ち下降運転の場合には、図示は省略するも踏段半転補助機構１０の回転方向を上部側の水平部４Ｂの中において矢印Ｐと反対の時計回り方向に回転させて踏段５を下ろすように上部側の往路側末端レール（末端レール９と同様のもの）から復路側末端レール（末端レール８と同様のもの）へと踏段５を平行半転させるものである。このようにして両水平部４Ａ，４Ｂの中で踏段５を平行に半転させることにより、従来例の後者のように薄型のエスカレーター装置１を得ることができ、さらに上記のように保守点検作業時の保守員Ｈ用の安定した足場が形成され、その作業の安全性と効率の向上を図ることができる。この安定的な足場の存在は、図１に符号ＨＡで示した階高が高く、傾斜部４Ｃの長さが長くなるほど保守員Ｈの疲労の軽減に有効となる。
【０００９】
なお、上記の踏段半転補助機構１０は、例示のものに限定されるものではなく、例えば図３の駆動歯車７の所で、踏段５の両側部に密着する回転式磁力板を設けて、その磁力による吸着力で踏段５を押上げあるいは下ろす平行半転を行うものでもよい。本発明は、回転することによって踏段５の半転を補助する機構であればその構成を問うものではない。
【００１０】
【発明の効果】
以上説明したように、本発明によれば、機械内部の保守点検を行う際、安定的な足場を形成して作業の安全と効率化に寄与し得る踏段復路の構成を備えた、薄型のエスカレーター装置を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an escalator device, and more particularly to a traveling arrangement of a step reciprocating path and a configuration of a half-turn mechanism.
[0002]
[Prior art]
In general, the escalator device travels with the tread surface forming an upward horizontal surface on the outward path between the upper and lower floors, and conversely, on the return path, the tread surface forming a downward inclined surface along the inclined portion. The structure of the reversing reciprocating path (for example, Japanese Utility Model Publication No. 4-55016) is used. Also, on the outward path of the step, the surface of the tread forms an upward horizontal surface as described above, while the surface of the tread also faces upward on the return path, and the parallel half travels while forming a slope along the installation angle of the escalator. A configuration of a rotary reciprocating path (for example, JP-A-1-242389) has also been proposed.
[0003]
[Problems to be solved by the invention]
The former of the above-mentioned known examples is the most common step running system. However, the vertical dimension of the total reciprocating path of this step is large, and the entire escalator device (especially the height of the machine trunk) is enlarged, so that the building is enlarged. There was a problem of excessive space occupying the space. For this reason, thin escalators intended to reduce the height of the machine body as in the latter known example have been proposed, but these known examples commonly use the inside of the escalator device, particularly the steps on the outward path side. There has been no consideration given to ensuring the safety of maintenance personnel and improving work efficiency when removing and performing maintenance and inspection of the machinery, and improvements in these aspects have been desired. That is, in the former case of the known example, when the steps on the outbound side are removed and the maintenance staff inspects or repairs the inside of the machine, the scaffolding is maintained by the uneven structure on the back side of the steps, especially the presence of many riser plates. This was an obstacle that hindered personnel from maintaining a stable posture and walking, and imposing danger. In order to solve this obstacle, there is an example of mounting a scaffolding device (Japanese Patent Application Laid-Open No. 10-279251) for flattening the unevenness of the return path in a state where the steps on the outward path are removed, and coping with safe work. It had the unwelcome drawback of a significant decrease in efficiency and the need for transport or storage space for the device. Further, the latter known example can realize a thin escalator in which the step is flat on the return path and the machine trunk height of the step reciprocation path is small, while the above-mentioned uneven obstacle as a work scaffold is eliminated. However, there was a serious safety problem that the slope formed by the treads was slippery and caused a maintenance worker to slide down.
[0004]
An object of the present invention is to provide a low-profile escalator having a step return path that can form a stable work platform and contribute to work safety and efficiency when performing maintenance and inspection inside a machine housed in a frame. It is to provide a device.
[0005]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a long frame having a horizontal portion connected to one of the entrance and exit floors and the other entry and exit floor, an inclined portion connecting the two horizontal portions, Steps which are connected endlessly in the longitudinal direction, are formed in a substantially triangular shape with a tread plate and a riser plate, and travel on guide rails, and are stored in both horizontal parts and return the steps from the forward path or the return path. In the one provided with a driving gear for performing a half-parallel drive over the step, the step has a step-like shape with the surface of the step facing upward on the forward path, and a step-like shape with the surface of the step plate facing upward substantially on the returning path. And a step-half-turn assist device for parallel-half-turning the step from the forward path to the return path or from the return path to the forward path is provided in the vicinity of the drive gear, and the step-half rotation assist mechanism includes a step kick. Up The rotational force in contact with the plate is obtained so as to be constituted by a rotary body which Hanten the footstep.
[0006]
In the above-described configuration, the step board secures a substantially horizontal surface on the return path of the step and forms a number of orderly stairs as in the outward path.Therefore, when performing maintenance and inspection inside the machine after removing the step on the outward path, The escalator device can be provided that has a stable attitude of a maintenance person located at a position, is effective in improving safety and work efficiency, and is thin.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 is an overall side view of a normal state of the escalator apparatus 1, FIG. 2 is an overall side view showing a maintenance and inspection work state of the escalator apparatus 1 of FIG. 1, and FIG. It is a side view which shows a structure. The escalator device 1 includes a long frame 4 having a horizontal portion 4A, a horizontal portion 4B, and an inclined portion 4C straddling between one of the floors 2 on the lower side and the other floor 3 on the upper side, The step 5 which is endlessly connected in the longitudinal direction of the frame 4 and has a substantially triangular shape with a tread plate 5a having a horizontal surface on which a passenger rides and a riser plate 5b closing the rear surface thereof and running on a guide rail is provided at both horizontal portions. As shown in FIG. 3, the passengers are transported in the forward M section while turning in a parallel state by a semicircle from the forward travel M to the return travel N or from the return travel N to the forward travel M in 4A and 4B. . The arrangement of the steps 5 is such that when performing maintenance and inspection of various safety devices, wiring connections, and handrail drive systems (all not shown) scattered in the escalator device 1, the steps 5 on the outward path M side are removed. In this case, as shown in FIG. 2, the step 5 of the return path N also has a configuration in which the tread plate 5a on which the passenger rides forms a horizontal or slightly inclined substantially horizontal plane, and the maintenance staff H can work on the substantially horizontal tread plate 5a. Has become.
[0008]
Here, the traveling (moving) of the steps 5 in the arrangement configuration of the steps 5 includes a step tune 6 for connecting the steps 5 endlessly and a pair of step rollers 5c and 5d as shown in FIGS. It can be practically used by the configuration of a guide rail (not shown) for traveling by a half-turn driving configuration shown in FIG. This will be described with reference to an example of a lower side of the internal configuration of the two horizontal portions 4A and 4B. A drive gear 7 which winds the step tune 6 and drives the step tune 6 and the step 5 in parallel and half-turn. 1 and 2, a step half-turn assist mechanism 10 for turning the step 5 in half along the end rails 8 and 9 of the guide rails not shown in FIG. 1 and FIG. The step 5 descending as shown by the arrow n passes through the opening 11 of the curved section 8A which is the half-turn locus of the terminal rail 8 on the return path N side, and moves to the curved section 9A of the terminal rail 9 on the outward path M side. In this case, the step 5 is achieved by being brought into contact with the step 5 and being pushed up by a rotational force rotating along the half-turn locus of the step 5. Here, the step half-turn assist mechanism 10 is provided with a rotational force on the arrow P side by a pair of drive wheels 10A, and a rotating body 10C that rotates along the half-turn locus of the step 5 while being guided by guide rollers 10B. 5, while rotating at the same speed in synchronization with the traveling speed of the step 5 while contacting the riser 5b of the step 5, the step 5 is pushed up by the frictional force between the rotating body 10C and the riser 5b, and The step rails 5a of the steps 5 are arranged in a step arrangement such that the step board 5a of the step 5 can be run upward from the terminal rails 8 to 9, that is, from the return path N to the forward path M in a half-parallel manner. When the step 5 rotates in the direction opposite to the arrows m and n, that is, when the step 5 is in a descending operation, the rotation direction of the step half-turn assist mechanism 10 is set to the direction indicated by the arrow in the upper horizontal portion 4B, although not shown. Step from the upper outward-side terminal rail (similar to terminal rail 9) to the return-side terminal rail (similar to terminal rail 8) so that step 5 is lowered by rotating in the clockwise direction opposite to P. 5 is turned in half parallel. By turning the steps 5 halfway in parallel between the two horizontal portions 4A and 4B in this manner, a thin escalator device 1 can be obtained as in the latter conventional example, and the maintenance and inspection work can be performed as described above. A stable scaffold for the maintenance staff H at the time is formed, and the safety and efficiency of the work can be improved. The presence of this stable scaffold is effective in reducing the fatigue of the maintenance staff H as the floor height indicated by the symbol HA in FIG. 1 is high and the length of the inclined portion 4C is longer.
[0009]
Note that the step half-turn assist mechanism 10 is not limited to the illustrated one. For example, a rotary magnetic force plate that is in close contact with both sides of the step 5 is provided at the drive gear 7 in FIG. A parallel half-turn that pushes up or down the steps 5 may be performed by the attraction force of the magnetic force. The present invention does not matter the configuration of the mechanism as long as it is a mechanism that assists half-turn of the step 5 by rotating.
