Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a spiral type passenger conveyor, and more particularly to a rail supporting a treadle.

[Prior art]

There are two types of conventional passenger conveyors: an escalator that goes up and down at an inclination angle of 30' and an electric road with a gentle inclination, and the characteristics of each have been utilized to become popular in many areas. but,
Recently, people are not satisfied with the linear transportation function of these two models, and there is a growing demand for spiral passenger conveyors that can provide passengers with a wide field of view. The spiral type, for example, has the advantage of providing a panoramic view of the inside of the store, giving a wide view of the products on display, and is attracting attention for its ability to increase the desire to purchase more than conventional passenger conveyors.

[Purpose of the invention]

The object of the present invention is to smoothly connect the inner and outer rails in the spiral part, curved rail part, and horizontal part, thereby enabling safe and smooth running on the treads from the top of the board to the bottom of the bottom, similar to conventional escalators. We provide a spiral man conveyor that allows you to

[Summary of the invention]

Generally, the escalator rail is the horizontal part at the entrance/exit,
It consists of an inclined section for lowering or ascending passengers and an R section connecting these two sections.

However, in a spiral type passenger conveyor, each rail is twisted, and the rail shape must be determined based on the absolute condition that the ratio of the travel distance between the inside and outside of the treads running on these rails must be the same for each part. was difficult. As a way to solve this problem, if the inner and outer rails are spiral lines that follow the surfaces of two concentric cylinders,
There were methods such as changing the radius of curvature from the cylindrical axis and the axis position of the spiral part and the horizontal part. However, in this case, there is no curved rail, so the tread must run on a rail that has discontinuities. In the present invention, a curved rail connecting the spiral portion and the horizontal portion is provided, and a horizontal adjustment rail is provided in order to eliminate the increase (or decrease) in the length ratio of the inner and outer rails that occurs when the curved rail is provided. Ta.

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

As shown in Fig. 1, the two inner and outer rails 2a and 2b on which the tread l rests are drawn along the inner and outer cylindrical surfaces, and if they are used as feeder lines, they can be unfolded and drawn in a plane. is the second

Equal to the ratio of the rail length at the spiral part and the vertical height of the curved rail, that is, Cz Dz , C2

Therefore, a length adjustment rail corresponding to Cl01' in FIG. 2 was provided to solve the above problem. In this case, the tread on the curved rail section is not strictly horizontal, but its inclination is the only limit.

〔Effect of the invention〕

According to the present invention, by setting the rails of the spiral passenger conveyor, it is possible to run the treads smoothly like a conventional escalator.
