Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to escalator balustrades, and particularly to transparent, translucent, or opaque balustrade panels made of glass or synthetic resin, and handrail belts that are directly attached to the balustrade panels. Regarding the structure that guides the.

[Technical background]

Conventionally, escalator balustrades are constructed by continuously attaching balustrade panels 2A, 2B, 2C, etc. made of glass, synthetic resin, etc. to a main body 1 as shown in Fig. as,
A handrail deck board 3 and a handrail rail 4 are provided in a continuous manner and are integrally attached with screws 5.
As shown in FIG. 3, a large number of rollers 6 are provided to guide the handrail belts at the end of the upper and lower handrails in order to reduce rolling friction. The handrail belt 7 is fitted into this, and the handrail belt 7 is rotated up and down to reduce the running resistance of the rotating part.

However, in this case, when installing the handrail, for example, when the building wall 9 is close, the screws 10 from the back side of the handrail deck board 3 must be removed.
The problem was that it was difficult to install.
Furthermore, many parts such as the mounting bracket 8, the handrail deck board 3, and their accessories are required between the balustrade panel 2 and the handrail rail 4, and much labor is required for processing, assembly, and installation.

[Purpose of the invention]

The present invention was made based on the above technical background, and in order to reduce the number of parts and reduce the running resistance of the handrail belt when the handrail deck board at the end of the handrail is removed.
The purpose is to reduce the running resistance of the handrail belt in the natural, curved, and straight parts of the handrail.

[Summary of the invention]

The present invention relates to a method for removing handrail deck boards and attaching handrail guide devices such as straight handrail rails to straight and curved sections in order to further enhance the transparency of escalator balustrades.

In particular, escalators have panels with glass or synthetic resin attached to the railings and rubber handrail guides attached directly along the periphery of the panels.
Roller devices are provided along the peripheral edges of the upper and lower ends of the upper and lower ends (folded portions) so as to overlap in the thickness direction of the panel, and the roller devices are configured to protrude from the outer end surface of the edge frame or the panel end surface. The present invention relates to an escalator railing characterized by the following.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

(Structure and operation of the invention) In FIGS. 4 to 6, panels 2A, 2B, and 2C are shown to constitute a handrail on the escalator body 1.
Attach a handrail rail (excluding the top and bottom ends) to the upper side of the handrail in a continuous manner. As shown in FIG. 5, the upper and lower ends and the new part (folded part) have a U-shaped cross section along the periphery of the panel 2A.
A curved edge frame 11 having a U-shape as a whole is attached along the panel 2A. Roller devices 12 are provided on both sides of the edge frame 11 in parallel with the panel 2A, and the roller devices 12 are provided to protrude from the outer end surface 11A of the edge frame 11 (or the panel 2A). FIG. 6 shows a cross-sectional view of the attachment part between the edge frame 11 and the panel 2A, in which a notch 13 is provided in advance in the panel 2A, and a synthetic rubber or polymer material is provided in that part to prevent damage to the bolt 14 and the panel 2A. A plastic bushing such as wood is inserted and joined together.

FIG. 7 is a perspective view of a roller device for guiding the handrail belt at the upper and lower ends of the manual parts,
It has a mounting hole (through hole) 16 provided in the edge frame 11, and a plurality of roller devices are integrally attached to the side surface thereof by welding 17. Each of these components is composed of an edge frame 11 shown in FIG. 8, and a roller device 12, as shown in FIG. Ru.

On the other hand, the panel 2A is processed into a shape in which one side is linear and the other part is U-shaped and partially circular.
A plurality of notches 13 are provided on the U-shaped processed side portion to match the pitch of the mounting holes 16 of the edge frame 11.

At least the edge frame 11 is shown in FIGS. 5 and 6.
As shown in the figure, it is provided so as not to protrude from substantially the same plane as the handrail belt 7 from the direction of arrow B.

The above-mentioned parts are assembled as shown in FIG. 4, and a handrail belt 7 is attached to guide the handrail in a movable manner.

According to the above configuration, the edge frame 11 attached to the peripheral edge of the panel 2A protects the strength of the panel 2A and enables welding attachment as a base for attaching the roller device 12 .

A bushing 15, which is a buffer member, is interposed to protect the joint between the notch 13 of the panel 2A and the bolt 14.

The roller device 12 is provided with a plurality of rollers 19, and the roller device 12 is provided with the panel 2A in between.
are arranged in double rows, and a large number of rollers 19 are provided in order to reduce the contact surface pressure between the rollers 19 and the handrail belt 7 at the turning portion of the handrail belt 7.

In addition, the roller 19 is made of a ball bearing mounted on the shaft or a metal material that is processed into a hollow cylindrical shape and then a high-molecular low-friction material such as tetrafluoroethylene resin is baked or a bushing is inserted into the inner diameter part (sliding rotation surface). It can also be configured as follows.

As shown in FIG. 11, the edge frame 11 and the roller frame 18
It is also possible to form a common edge frame body 20 in which the two are integrated.

This edge frame body 20 is manufactured by bending a thin plate or using a shaped material (Al extrusion material, roll homing).
etc. can also be used.

〔Effect of the invention〕

According to the present invention, the handrail belt reversing portion can be guided by a roller device without attaching a handrail deck board to the panel constituting the handrail, and the running resistance of the handrail belt can be reduced.

In addition, the handrail rail can be installed to the parapet panel by storing it almost within the C-shaped cross-sectional curve of the handrail belt (within the width), and installation is easy.
Furthermore, the handrail deck board and its accessories are no longer necessary, and the running resistance of the bent portion of the handrail belt at the tip end part of the handrail is reduced, making it possible to extend the life of the handrail belt.
