Description

本発明は、エスカレーターや動く歩道などの乗客コンベアに係り、特に、移動手摺（ハンドレール）の支持部材の構成に関する。   The present invention relates to passenger conveyors such as escalators and moving walkways, and more particularly to the configuration of support members for moving handrails (handrails).

従来、乗客コンベアの移動手摺を支持する手摺ガイドは、幅方向について左右一対の部材で構成され、これらの上面をブラケットで押さえ、このブラケットをボルトでガイドフレームへ固定している。このような、手摺ガイドの固定方法は、例えば、下記特許文献１に記載されている。   Conventionally, a handrail guide that supports a moving handrail of a passenger conveyor is constituted by a pair of left and right members in the width direction, and these upper surfaces are pressed by brackets, and the brackets are fixed to a guide frame by bolts. Such a method for fixing the handrail guide is described, for example, in Patent Document 1 below.

特開平５−７８０８０号公報（図３等）Japanese Patent Laid-Open No. 5-78080 (FIG. 3 etc.)

しかしながら、上述のような手摺ガイドの固定方法では、移動手摺の長手方向について多数のボルトを用いてガイドフレームに固定しなければならず、取付け作業が大変であった。また、移動手摺との摺動に伴い手摺ガイドの外周面が磨耗した結果、手摺ガイドの交換が必要になる場合があるが、その際の交換作業も容易ではない。更に、手摺ガイドが磨耗すると、移動手摺が金属製のボルトやブラケットと接触して移動手摺の内周面の帆布を傷つけ、移動手摺の駆動状態に悪影響を与えたり、移動手摺の交換時期を早めたりする可能性もある。   However, in the method for fixing the handrail guide as described above, it is necessary to fix the guide rail to the guide frame using a large number of bolts in the longitudinal direction of the moving handrail, and the mounting work is difficult. Further, as a result of the outer peripheral surface of the handrail guide being worn as it slides with the moving handrail, the handrail guide may need to be replaced, but the replacement work at that time is not easy. Furthermore, if the handrail guide wears, the moving handrail comes into contact with the metal bolts and brackets and damages the canvas on the inner peripheral surface of the moving handrail, adversely affects the driving state of the moving handrail, and accelerates the replacement time of the moving handrail. There is also a possibility.

従って、本発明の目的は、手摺ガイドの取付けや交換が容易で、移動手摺の安全性や寿命を高めた乗客コンベアを提供することである。   Accordingly, an object of the present invention is to provide a passenger conveyor in which the handrail guide can be easily attached and replaced, and the safety and life of the moving handrail are enhanced.

上述の目的を達成するために、本発明では、踏段に同期して循環移動する移動手摺と、この移動手摺の移動方向に沿って立設された欄干パネルと、この欄干パネルの周縁に取付けられたガイドフレームと、このガイドフレームの外周側を覆って前記移動手摺を案内する手摺ガイドを備えた乗客コンベアにおいて、前記ガイドフレームの外周側の一部に凹部を設け、前記手摺ガイドを幅方向について左右一対のガイド片で形成し、これらガイド片が互いに当接する対向部を有し、これら対向部の少なくとも一部を前記凹部へ挿入し、前記互いに当接する対向部が押し付けあい前記ガイド片の離脱を防止し、前記ガイド片のうち前記凹部へ挿入されている部分が先細りとなるような斜面を有するとともに引掛り部を有し、前記ガイドフレームがその凹部の入口近傍に出張り部を有し、前記引掛り部と前記出張り部とにより前記ガイド片と前記ガイドフレームとが係止されて、前記左右一対のガイド片を前記ガイドフレームに保持した。
In order to achieve the above-mentioned object, in the present invention, a moving handrail that circulates in synchronization with a step, a balustrade panel erected along the moving direction of the moving handrail, and a peripheral edge of the balustrade panel are attached. In the passenger conveyor provided with a guide frame and a handrail guide that covers the outer peripheral side of the guide frame and guides the moving handrail, a recess is provided in a part on the outer peripheral side of the guide frame, and the handrail guide is arranged in the width direction. A pair of left and right guide pieces, each of which has a facing portion that abuts against each other, inserts at least a part of the facing portion into the recess, and the facing portions that abut each other press against each other to release the guide piece The guide piece has a sloped surface such that the portion inserted into the recess is tapered and has a catching portion, and the guide frame is A protruding portion is provided in the vicinity of the entrance of the recess, and the guide piece and the guide frame are locked by the hook portion and the protruding portion, and the pair of left and right guide pieces are held by the guide frame. .

本発明によれば、手摺ガイドの取付けや交換が容易で、移動手摺の安全性や寿命を高めた乗客コンベアを提供できる。   According to the present invention, it is possible to provide a passenger conveyor in which the handrail guide can be easily attached and replaced, and the safety and life of the moving handrail are enhanced.

本実施形態は、乗客コンベアの一例であるエスカレーターに本発明を適用したものであり、図１は、その乗降床１付近を示したものである。本実施形態のエスカレーターは、この乗降床１から他方の乗降床（図示せず）にかけて、無端状に連結された踏段２が循環移動し、この踏段２と同期して移動手摺３も循環移動するように構成されている。また、踏段２の長手方向の両端には、欄干部が設置されており、この欄干部の上端付近における、移動手摺３及びその支持構造の詳細は、図２に示す通りである。すなわち、この欄干部は、移動手摺３の移動方向に沿って立設された欄干パネル４と、この欄干パネル４の周縁に取付けられたガイドフレーム５と、このガイドフレーム５の外周側を覆って移動手摺３を案内する手摺ガイド８などで構成されている。尚、本実施形態では、欄干パネル４として、ガラスパネルを採用している。   In the present embodiment, the present invention is applied to an escalator which is an example of a passenger conveyor, and FIG. 1 shows the vicinity of the boarding / exiting floor 1. In the escalator of the present embodiment, a step 2 connected endlessly circulates from this boarding / exiting floor 1 to the other boarding / unloading floor (not shown), and the moving handrail 3 also circulates in synchronization with the step 2. It is configured as follows. Moreover, balustrades are installed at both ends of the step 2 in the longitudinal direction, and details of the movable handrail 3 and its supporting structure in the vicinity of the upper end of the balustrade are as shown in FIG. That is, the balustrade part covers the balustrade panel 4 erected along the moving direction of the moving handrail 3, the guide frame 5 attached to the periphery of the balustrade panel 4, and the outer peripheral side of the guide frame 5. A handrail guide 8 for guiding the moving handrail 3 is formed. In the present embodiment, a glass panel is employed as the balustrade panel 4.

また、ガイドフレーム５は、その内周側が略Ｕ字状となっており、この略Ｕ字状の部分を欄干パネル４の上端に嵌め込んで固定されている。一方、ガイドフレーム５の外周側の中央近傍には凹部７が設けられ、ガイドフレーム５の外周側の幅方向両端には爪部５ａ，５ｂが設けられている。ここで、「内周側」とは、移動手摺３の移動経路に対して内側を意味し、「外周側」とは、その移動経路に対して外側を意味する。   Further, the guide frame 5 has a substantially U-shape on the inner peripheral side, and the substantially U-shaped portion is fitted and fixed to the upper end of the balustrade panel 4. On the other hand, a recess 7 is provided in the vicinity of the center on the outer peripheral side of the guide frame 5, and claw portions 5 a and 5 b are provided at both ends in the width direction on the outer peripheral side of the guide frame 5. Here, “inner circumference side” means inside the movement path of the moving handrail 3, and “outer circumference side” means outside the movement path.

そして、ガイドフレーム５の凹部７の入口近傍には、幅方向内側の向きへ突出した出張り部６ａ，６ｂが形成されている。ここで、「幅方向内側」とは、移動手摺３の幅方向について中央寄りを意味し、「幅方向外側」とは、その幅方向について両端寄りを意味する。尚、ガイドフレーム５の材質としては、例えば、アルミなどが用いられている。   In the vicinity of the entrance of the concave portion 7 of the guide frame 5, projecting portions 6 a and 6 b projecting inward in the width direction are formed. Here, “inward in the width direction” means near the center in the width direction of the moving handrail 3, and “outside in the width direction” means near both ends in the width direction. For example, aluminum is used as the material of the guide frame 5.

更に、手摺ガイド８は、移動手摺３の幅方向について左右一対のガイド片８ａ，８ｂで構成されており、いずれのガイド片８ａ，８ｂも、プラスチックなどの樹脂製であって、移動手摺３の摺動材としての役割を果たしている。そして、これらガイド片８ａ，８ｂの互いに向かい合う側、すなわち、幅方向内側は、内周側へ延在し、互いに当接する対向部を形成している。また、これらガイド片８ａ，８ｂの幅方向内側の内周側端、又は、これら対向部の少なくとも一部は、共通の凹部７へ挿入されている。更に、ガイド片８ａ，
８ｂのうち凹部７へ挿入されている部分の一部が、幅方向外側へ突起して鍵状の引掛り部９ａ，９ｂを形成している。尚、ガイド片８ａ，８ｂの幅方向外側には、内周側へ変形した湾曲部を有している。 Further, the handrail guide 8 is composed of a pair of left and right guide pieces 8 a and 8 b in the width direction of the movable handrail 3, and both guide pieces 8 a and 8 b are made of resin such as plastic, It plays a role as a sliding material. The sides of these guide pieces 8a and 8b facing each other, that is, the inner side in the width direction, extend to the inner peripheral side and form opposing portions that come into contact with each other. Further, the inner peripheral side ends on the inner side in the width direction of these guide pieces 8 a and 8 b, or at least a part of these facing portions are inserted into the common recess 7. Furthermore, the guide piece 8a,
A part of the portion of 8b inserted into the concave portion 7 protrudes outward in the width direction to form key-like hook portions 9a and 9b. In addition, it has the curved part which deform | transformed to the inner peripheral side in the width direction outer side of guide piece 8a, 8b.

また、ガイド片８ａ，８ｂは、その外周面の一部、具体的には、その外周面の幅方向内側の部分に、手摺駆動装置（図示せず）のローラと略同じ幅寸法の溝部１０が設けられている。そして、この溝部１０の幅方向についての位置は、手摺駆動装置のローラの幅方向についての位置と略同一である。つまり、移動手摺３の内周面のうち、手摺駆動装置のローラに圧接される部分については、手摺ガイド８の外周面と接触しないようにし、手摺駆動装置のローラと移動手摺３との間の摩擦係数への影響や移動手摺３の低寿命化を抑制している。また、溝部１０の表面に、手摺ガイド８の他の表面と比べて高い摩擦係数となるような加工を施し、手摺駆動装置からの駆動力を効率的に得ることも可能である。   Further, the guide pieces 8a and 8b have a groove portion 10 having a width dimension substantially the same as that of a roller of a handrail driving device (not shown) on a part of the outer peripheral surface, specifically, on the inner side in the width direction of the outer peripheral surface. Is provided. And the position about the width direction of this groove part 10 is substantially the same as the position about the width direction of the roller of a handrail drive device. In other words, the portion of the inner peripheral surface of the moving handrail 3 that is in pressure contact with the roller of the handrail driving device is not in contact with the outer peripheral surface of the handrail guide 8, so that the portion between the roller of the handrail driving device and the moving handrail 3 The influence on the friction coefficient and the life reduction of the moving handrail 3 are suppressed. In addition, the surface of the groove portion 10 can be processed so as to have a higher coefficient of friction than the other surface of the handrail guide 8 to efficiently obtain the driving force from the handrail driving device.

ここで、手摺ガイド８のガイドフレーム５への取付け方について、図３を用いて説明する。まず、一方のガイド片８ａの湾曲部を、ガイドフレーム５の爪部５ａに嵌め込んでから、ガイド片８ａの引掛り部９ａを下方へ移動させ、ガイドフレーム５の凹部７へ挿入し、この引掛り部９ａと上述の出張り部６ａ，６ｂとを係止させ、ガイド片８ａをガイドフレーム５に保持する。   Here, how to attach the handrail guide 8 to the guide frame 5 will be described with reference to FIG. First, after fitting the curved portion of one guide piece 8a into the claw portion 5a of the guide frame 5, the hooking portion 9a of the guide piece 8a is moved downward and inserted into the concave portion 7 of the guide frame 5, The hook portion 9 a and the above-described protruding portions 6 a and 6 b are locked, and the guide piece 8 a is held on the guide frame 5.

次に、ガイド片８ｂを、ガイド片８ａと同様に、ガイドフレーム５に取付けると、ガイド片８ａ，８ｂの互いの対向部が押し付けあい、ガイド片８ａ，８ｂの脱離が防止できる。また、ガイドフレーム５の出張り部６ａ，６ｂと、手摺ガイド８の引掛り部９ａ，９ｂとにより、移動手摺３の走行中に水平方向の外力が加わった場合でも、手摺ガイド８が脱離せず、エスカレーターの安全性が確保できる。   Next, when the guide piece 8b is attached to the guide frame 5 in the same manner as the guide piece 8a, the opposing portions of the guide pieces 8a and 8b are pressed against each other, so that the guide pieces 8a and 8b can be prevented from being detached. Further, even when a horizontal external force is applied during the traveling of the moving handrail 3 by the projecting portions 6a and 6b of the guide frame 5 and the catch portions 9a and 9b of the handrail guide 8, the handrail guide 8 is detached. Therefore, the safety of the escalator can be secured.

このように、本実施形態によれば、ボルトなどの固定手段を別途用いなくても、手摺ガイド８をガイドフレーム５に保持できるので、取付け作業が容易になるばかりか、結果として、部品点数の減少による製作費の低減が期待できる。更に、移動手摺３との摺動により手摺ガイド８が磨耗した場合に、手摺ガイド８を交換する作業も容易になる。   Thus, according to the present embodiment, the handrail guide 8 can be held on the guide frame 5 without using a fixing means such as a bolt, so that not only the mounting operation is facilitated, but also the number of parts can be reduced. The production cost can be expected to decrease due to the decrease. Furthermore, when the handrail guide 8 is worn due to sliding with the moving handrail 3, the work of replacing the handrail guide 8 is facilitated.

また、手摺ガイド８が磨耗して、その溝部１０の上面が移動手摺３と接触しても、ボルトなどと接触した場合と異なり、移動手摺３の内周面の帆布を傷つける可能性は少ない。したがって、移動手摺３の駆動状態への悪影響を回避したり、移動手摺３の交換時期を長くしたりすることが可能であり、その結果、移動手摺３の安全性や寿命を高めたエスカレーターが提供できる。   Further, even if the handrail guide 8 is worn and the upper surface of the groove portion 10 is in contact with the moving handrail 3, unlike the case where it is in contact with a bolt or the like, there is little possibility of damaging the canvas on the inner peripheral surface of the moving handrail 3. Therefore, it is possible to avoid an adverse effect on the driving state of the moving handrail 3 or to lengthen the replacement time of the moving handrail 3, and as a result, an escalator that improves the safety and life of the moving handrail 3 is provided. it can.

尚、上記本実施形態では、踏段２間に段差が生じるエスカレーターについて説明したが、乗客コンベアの他の一例である動く歩道についても同様の構成を採用することができる。したがって、本明細書中で使用した踏段という用語には、動く歩道のパレットの意味も含まれる。   In addition, although the said embodiment demonstrated the escalator which a level | step difference produces between the steps 2, the same structure is employable also about the moving walkway which is another example of a passenger conveyor. Accordingly, the term step used herein includes the meaning of a moving sidewalk pallet.
