The passenger conveyor is provided with handrails or hand belts for endless movement with the step of placing and moving the passengers and for gripping the passengers without losing balance.

As shown in FIG. 4, the hand belt 1 is made of a steel wire for reinforcement between layers of a core body 4 formed by laminating a plurality of canvases 2 with an adhesive 3 and having a substantially C-shaped cross section. A plurality of wire cords 5 made of twisted wires or the like are sandwiched between the core body 4
The decorative rubber layer 6 is laminated to improve the durability of the passenger conveyor, which is attached to a hand belt mounting rail of a passenger conveyor that is endlessly rotated and used. Has been.

As a reinforcing material for such a hand belt for a passenger conveyor, in addition to the wire cord 5, as shown in FIG. 5, a flat metal strip 7 such as a steel tape or a synthetic fiber cloth has been used.

[0005]

However, the one using the synthetic fiber cloth as the reinforcing material cannot obtain sufficient strength, and the one using the wire cord is composed of the stranded wire of the steel wire and the like. Stranded wire is cut by pinching, sagging, etc.,
In some cases, the cut end may even reach the surface of the decorative rubber layer 6. Therefore, the number of wire cords must be increased in order to improve the reinforcing property, which is not economical.

Further, in the case of the metal flat belt 7, the deformation in the cross-sectional direction is suppressed and a sufficient reinforcing force as an elongation stopper is obtained, but since the metal flat belt 7 is a continuous body, the adhesion with the canvas 2 is weak and the durability is long. The sex has deteriorated. Therefore, the surface of the metal flat strip 7 is roughened to increase the surface area of the metal flat strip 7, and an adhesive is applied to the surface to allow the adhesive to penetrate into the fine irregularities formed on the surface to adhere to the canvas. I have to plan
The number of processes has increased and the cost has increased.

The present invention has been made in order to solve the above-mentioned drawbacks and provides sufficient reinforcement to prevent the handbelts for passenger conveyors from stretching, and also has strong adhesion to canvas, which improves durability and is inexpensive. It is an object of the present invention to provide a handrail for a passenger conveyor that can be manufactured at any time.

[0008]

In order to achieve the above object, a handrail for a passenger conveyor according to the present invention comprises a core body made of canvas having a substantially C-shaped cross section and laminated with an adhesive.
In a passenger conveyor hand belt consisting of a reinforcing member made of a metal flat belt provided in the core body and a decorative rubber layer laminated on the core body, the reinforcing material has a plurality of perforations through which an adhesive intervenes. is there.

[0009]

A metal flat strip is used as a reinforcing material provided between layers of a core body made of canvas having a substantially C-shaped cross section laminated with an adhesive. Perforations are provided in the metal flat strip at a predetermined pitch.
Therefore, the adhesive enters the perforations, the adhesives above and below the metal flat belt are integrated, and the metal flat ribbon and the canvas are firmly bonded.
Therefore, it is possible to improve durability while having a sufficient reinforcing force to prevent stretching. Moreover, since the number of processes can be reduced, the passenger conveyor hand belt can be manufactured at low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment to which a hand belt for a passenger conveyor of the present invention is applied will be described with reference to the drawings. As shown in FIG. 1, the passenger conveyor hand belt 10 shown in FIG.
A decorative rubber layer 60 was laminated by sandwiching a metal flat belt 50, which is a reinforcing material, between layers of a core body 40 formed by laminating a plurality of canvas 20 with an adhesive 30 and having a substantially C-shaped cross section. It is a thing.

3 to 7 sheets of the canvas 20 are laminated, are rigid, and are bent and formed by pressing a large number of rollers. As the adhesive 30, so-called rubber glue or the like is used,
Chloroprene rubber, styrene-butadiene rubber or the like may be applied to the canvas 20 in advance so that the rigid canvases 20 are adhered to each other.

The metal flat belt 50 provided in the central portion between the laminated canvas 20 is made of steel tape such as steel and has a desired width. The metal flat belt 50 is provided with perforations 51 at predetermined intervals. As shown in FIG. 2, for example, two rows are provided with a desired pitch d. As shown in FIG. 3, the size of the perforations 51 may be such that the perforations 51 have a diameter a through which the adhesives 30 above and below the flat metal strip 50 enter each other. Perforation 51
The adhesive 30 applied to the canvas 20 in the upper and lower layers of the metal flat belt 50 enters the metal flat belt 50, and the metal flat belt 50 is integrated with the upper and lower adhesives 30 and firmly bonded to the canvas 20. The shape of the perforations 51 may be any shape such as a circle or an ellipse.

Such a passenger conveyor hand belt is mounted on a hand belt mounting rail (not shown) of the passenger conveyor which is endlessly driven to rotate. The passenger conveyor handrail having such a configuration is manufactured by laminating the canvas 20 applied with the adhesive 30 and supplying the adhesive 20, and the metal flat belt 50 in which the perforations 51 are previously provided between the desired canvas 20. To supply. After that, a large number of rollers are pressed to make the cross section substantially C-shaped to form the core body 40. An unvulcanized decorative rubber is placed on the core 40, heated and vulcanized to form the decorative rubber layer 6
