Abstract

PURPOSE:To reduce the running resistance in a handrail as well as to prevent any adverse effect due to rainwater by forming the handrail in a horizontal traveling part of a footstep, into a gentle slope way, lowering the side of a lower platform as far as one step. CONSTITUTION:An intermediate horizontal type passenger conveyor 1 with an intermediate horizontal passage C consists of a horizontal passage A, a slope way B, the said intermediate horizontal passage C, another slope way D at the lower side and a horizontal passage E at the upper side. A return passage of a handrail 6 is set down to a locus along these slope ways B, D, but at a return passage F in a part of the intermediate horizontal passage C, the side of the slope way B is formed into such a gentle slope way as situated one step lower. At a projecting bend part, a guiding rotor 7 is supported on the surface side of the handrail 6 and at a recess bend part, a rotor 8 comes into contact with the inner circumferential side and supported as well. Consequently, the return passage side of the handrail 6 is formed into a smooth, gentle slope way owing to the horizontal part C so that running resistance is reduced, while rainwater penetrating into an upward opening is made to flow down to the lower part, thus a slip or the like due to the rainwater is prevented.

具合があった。The above-mentioned prior art is an invention centered on steps, and does not disclose an improvement idea for preventing slippage of the handrail and increasing running resistance by adding an intermediate horizontal portion. In this type of passenger conveyor, running resistance on the return path of the handrail increases particularly at the bent portions (the horizontal portion and the return path before and after the horizontal portion), causing handrail slippage and damage to the drive system. Additionally, when installed outdoors, rainwater collects on the inner periphery of the handrail, increasing the risk of slipping.

本発明の目的は、ハンドレールの走行抵抗を減じる一方
、雨水の悪影響を軽減することにある。An object of the present invention is to reduce the running resistance of a handrail while also reducing the adverse effects of rainwater.

傾斜。In order to achieve the above objective, the return path of the handrail at the horizontal running part of the steps of the intermediate horizontal passenger conveyor is a gentle slope with the lower entrance side lowered one step, and the return path of the handrail is made to be a gentle slope with the lower entrance side lowered. Approximately the same slope angle as the step ramp,
The intermediate horizontal part has a gentle slope that is slightly lower on the lower entrance side than the horizontal level, and the slope angle on the upper entrance side is approximately the same as the slope of the steps.
Slope.

緩傾斜及び傾斜路で構成したものである。It consists of a gentle slope and ramp.

また、前記緩傾斜路と前記傾斜路が交わる部分に回転体

さらに、前記緩傾斜路の相当部を円弧状にすることも可

が減少する。The existence of the above-mentioned gentle slope means, for example, compared to the common-sense handrail return path configuration, which is an inclined, horizontal, and inclined trajectory,
The bending resistance of the handrail is reduced (changes in angle are no longer sudden), and the rainwater that has entered also falls toward the lower entrance, reducing its negative effects. Furthermore, by guiding with a rotating body, running resistance is significantly reduced compared to a sliding body guiding method.

なお、上記効果は緩傾斜路の範囲を大径の円弧状とする
ことでも発揮できる。Note that the above effect can also be achieved by making the range of the gentle slope into a circular arc shape with a large diameter.
