〔産業上の利用分野）
本発明はマンコンベヤ装置に使用される移動手摺の改良
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a moving handrail used in a passenger conveyor device.
エスカレータ等マンコンベヤ装置に使用される移動手摺
は、一般に、湾曲して形成された綿布と、この綿布上に
重着された芯体と、該綿布上に重着された断面横Ｃ字状
の化粧ゴムとから構成され、欄干のガイド部に無端状に
巻回配置される。Movable handrails used in passenger conveyor devices such as escalators generally include a curved cotton cloth, a core layered on the cotton cloth, and a horizontal C-shaped cross section layered on the cotton cloth. It is made of decorative rubber and is wound endlessly around the guide part of the balustrade.
そして、マンコンベヤにおける主枠内の手摺駆動装置の
駆動ローラと加圧ローラとに挾持されて摩擦力により循
環移動するようになっている。Then, it is held between a drive roller and a pressure roller of a handrail drive device in the main frame of the passenger conveyor and circulated by frictional force.
ところで、上記移動手摺を駆動ローラと加圧ローラとに
挾持させ摩擦力により循環移動させると、移動手摺の化
粧ゴム表面の艶が低下してしまうという問題を生じる。However, if the movable handrail is held between a drive roller and a pressure roller and circulated by frictional force, a problem arises in that the gloss of the decorative rubber surface of the movable handrail is reduced.
この艶の低下は、上記摩擦力の他に、乗客の手の平の手
垢、油や空気中の塵埃、乗客の悪戯によるガムや１ノシ
ートの化粧ゴムへの付着、そして、メーカー指定以外の
洗剤、クリーナー、溶剤等の使用によっても生じる。こ
れらの汚れは化粧ゴムに浸透固着して一般の清掃では除
去し難く、又指定以外の清掃剤や溶剤による化粧ゴムの
艶の回復は不可能である。そして、これらの汚れを放置
すると、マンコンベヤの運転時に化粧ゴム層に亀裂が生
じて事故を引き起こす虞れがあり、よって、化粧ゴムの
艶を低下させる汚染を確実に防止する必要がある。In addition to the above-mentioned frictional force, this decrease in luster is caused by dirt on the passenger's palm, oil and dust in the air, adhesion to the gum or cosmetic rubber of the sheet due to mischief by the passenger, and detergents and cleaners other than those specified by the manufacturer. , also caused by the use of solvents, etc. These stains penetrate and stick to the decorative rubber, making them difficult to remove by ordinary cleaning, and it is impossible to restore the luster of the decorative rubber using cleaning agents or solvents other than those specified. If these stains are left unattended, there is a risk that cracks will occur in the decorative rubber layer during operation of the passenger conveyor, causing an accident.Therefore, it is necessary to reliably prevent contamination that would reduce the luster of the decorative rubber.
この問題の解決策としては、従来、メーカー指定のクリ
ーナーを使用する定期的な清掃や化粧ゴム表面に汚染防
止作用を営むウレタン等からなる合成樹脂膜を形成する
もの（実開昭６０−３３５７０号公報参照）が採用され
ている。Conventional solutions to this problem include periodic cleaning using a cleaner specified by the manufacturer, and forming a synthetic resin film made of urethane or the like on the surface of the cosmetic rubber to prevent contamination (Utility Model Application No. 60-33570). (see official bulletin) has been adopted.
しかしながら、定期的な清掃は多くの時間と労力を費や
す欠点があり、又ウレタン等からなる合成樹脂膜を化粧
ゴムに用いる方法は以下の様な欠点を有していた。即ち
、■化粧ゴムを構成する合成ゴムは非極性であるので、
ウレタン等の塗料を化粧ゴム上に塗布しても付着性が悪
い。■塗布層際し、ウレタン等の塗料を溶剤で薄めて濃
度を下げ重ね塗りをする必要がある。■この重ね塗りの
方法を使用しても、移動手摺の屈曲移動によりウレタン
に切れや剥離が生じ艶の維持や汚染防止を１〜２年しか
図ることができない。However, periodic cleaning has the drawback of consuming a lot of time and effort, and the method of using a synthetic resin film made of urethane or the like for decorative rubber has the following drawbacks. In other words, ■Since the synthetic rubber that makes up the decorative rubber is non-polar,
Even when paints such as urethane are applied to decorative rubber, they have poor adhesion. ■When applying the coating layer, it is necessary to dilute the urethane or other paint with a solvent to lower the concentration and apply multiple coats. - Even if this method of multiple coatings is used, the urethane may break or peel due to the bending movement of the handrail, and maintenance of gloss and prevention of contamination can only be achieved for one to two years.
また、上記問題の解決策εして、通常のゴム用プライマ
ーやゴム糊の使用も考えられるが、これらはゴムを溶剤
で溶かしたものなので上塗り塗料との付着性に欠け、長
期に亘って艶の維持や汚染の防止を図ることができなか
った。In addition, as a solution to the above problem, it is possible to use ordinary rubber primer or rubber glue, but since these are made by dissolving rubber in a solvent, they lack adhesion with the top coat and do not maintain gloss over a long period of time. It was not possible to maintain the environment or prevent contamination.

実施が極めて困難であった。Furthermore, as a solution to the above problem,
Publication No. 82 discloses a method in which a preformed body for a moving handrail is prepared by forming a synthetic resin film on the upper surface of an unwashed rubber band, and then the preformed body is vulcanized into a C-shaped cross section. However, this manufacturing method significantly complicates the manufacturing process and is extremely difficult to implement.

A moving handrail is constructed of a C-shaped decorative rubber, a polyolefin primer coating layer applied to the surface of the decorative rubber, and a urethane coating layer applied on the polyolefin primer coating layer. There is.

染の防止に資する機能を営む。Hereinafter, the present invention will be described in detail based on an embodiment shown in Fig. 341. In the figure, (1) is a cotton fabric of a movable handrail constructed in a curved manner, and a core body (2) is placed on this cotton fabric (1). The cotton fabric (1) is covered with decorative rubber (3) with a C-shaped cross section (surface rubber).
I put a lot of weight on it. (4) is a polyolefin primer coating layer made of a polyolefin primer applied to the surface of this decorative rubber (3), and this polyolefin primer coating layer (4) has a solubility parameter similar to that of synthetic rubber, This function acts to improve or smooth the adhesion to the top urethane paint and the application, which conventional primers made by dissolving rubber in a solvent do not have. However, (5) is a urethane coating layer made of urethane paint applied on the polyolefin primer coating layer (4), and functions to maintain the gloss of the decorative rubber (3) and prevent contamination.

ドライヤー等を使用しても良い。Next, the method of manufacturing the movable handrail according to the present invention will be explained based on the manufacturing flowchart shown in FIG. 2. First, dirt on the decorative rubber surface of the movable handrail is removed by wiping with thinner or the like. This work is essential when applying a coating layer to the decorative rubber surface of used handrails. Next, cosmetic rubber (3)
A modified polyolefin primer having a solubility parameter similar to that of synthetic rubber is applied to the surface of the decorative rubber (3) to a thickness of approximately 15 μm.Then, the surface of the decorative rubber (3) is irradiated with far infrared rays at 80°C to 90°C or hot air is blown to form the polyolefin primer. is dried and firmly adhered to the surface of the decorative rubber (3). Note that a dryer or the like may be used for this drying work in the case of on-site construction.

Apply twice and then dry the urethane paint by drying at room temperature or baking.

摺の長期使用を図ることが期待できる。As described above, according to the present invention, since the polyolefin primer is applied to the surface of the decorative rubber (3), the application of the urethane paint can be made extremely smooth, and the adhesion of the urethane paint to the decorative rubber can be prevented. This makes it possible to significantly improve the elasticity of the handrail, and it is expected that the urethane will be reliably prevented from breaking or peeling as the handrail bends and moves, allowing for long-term use of the handrail with excellent aesthetics.

極めて容易にすることが可能となる。In addition, conventionally, the cosmetic rubber (3) was made of highly durable synthetic rubber such as C5M, which is expensive and easily colored, and the cosmetic rubber (3) was given a color combination according to the customer's needs. According to the present invention, inexpensive non-colored synthetic rubber (NBR, SBR
Since colored urethane paint can be applied to any color (e.g.), any color can be applied with the urethane paint itself, making it extremely easy to manufacture moving handrails by using inexpensive synthetic rubber as the decorative rubber (3). becomes possible.

することができる。Furthermore, in the past, if you wanted to change the color of a moving handrail that had been used for a long time and was difficult to remove dirt, you would replace it with a new one, but according to the present invention, it is possible to replace the moving handrail with a new one. Since colored urethane paint can be applied to the handrail to change its color and maintain its luster, dirty moving handrails can be refurbished very easily.
