Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to a parapet inner panel for a curved escalator.

[Prior art]

Conventionally, a curved escalator is known from Japanese Patent Publication No. 48-25559. Such a curved escalator will be explained with reference to FIGS. 1 and 2. In these figures, reference numeral 1 denotes a conveyance path, and the conveyance path 1 has an intermediate constant slope part A that slopes at a constant angle in the vertical direction, and the slope angle changes on both sides above and below.

The upper and lower horizontal parts are formed through the lower curved parts A and A,
Nuals connecting the outbound and return routes are formed at both ends of these sections. Reference numeral 2 denotes fan-shaped steps connected to each other that move along the conveyance path 1, and 3 and 4 denote outer peripheral sides that are erected on the main frame 5 along the longitudinal direction of the conveyance path 1.

The balustrades 6 and 7 on the inner circumferential side are movable handrails supported by the balustrades 3 and 4 and driven in synchronization with the step 2 described above.

The balustrade 3.4 is provided with inner panels 8, 9 on the outer circumference side and on the inner circumference side, which are divided in the longitudinal direction.

However, the curved escalator shown in Japanese Patent Publication No. 48-25559 does not show a specific structure of the inner panel of the handrail. In addition, in conventional curved escalators as shown in Figures 1 and 2, the conveyance path was configured with a constant radius of curvature, which made the overall structure, including the drive mechanism for the fan-shaped steps, complicated, resulting in high costs. There was a problem.

[Summary of the invention]

In order to solve the above-mentioned problems, the applicant of this invention
Patent Application No. 1833.15/1982 (October 19, 1982)
previously proposed a curved escalator equipped with a conveyance path with a constant slope in the middle, upper and lower curved portions with varying inclination angles, and upper and lower horizontal portions with different radii of curvature. In this curved escalator, since the inner panel of the balustrade is composed of a three-dimensional curved surface, the manufacturing cost is high (this is likely to occur), but in this invention, the outer and inner panels of the balustrade are constructed with a constant slope in the middle. , upper and lower curved parts, and upper and lower horizontal parts, and by configuring these parts into the shapes of parts of multiple types of cylindrical surfaces with different radii and configuring both end faces vertically, The purpose of this invention is to provide an inexpensive inner panel of a balustrade that can be manufactured using various types of molds.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 7.

In FIGS. 3, 4, and 5, the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts.

In this embodiment, railings 3 and 4 along the longitudinal direction of the conveyance path 1 are used.
The inner panels 8.9 on the outer and inner periphery sides have an intermediate constant slope part 10.11 corresponding to the conveyance path 1, an upper curved part tz, 13, and a lower curved part 14.15 with varying inclination angles. It is divided into upper and lower horizontal parts 16 and 17, and both end natural parts 18 and 19 that are continuous at both ends of the upper and lower horizontal parts, and is further divided into a large number of constant slope parts 10° and 11.

In addition, the intermediate constant slope portion 10.11 has a radius of curvature R,, R2 centered at point 0, and the slope angle changes, and the lower curved portion 1
2, 13, 14, 15 are curvature radius R3, R, upper and lower horizontal parts 16.17 are curvature radius R centered on points 0', 0''
3′.

R2'. Furthermore, the constant slope part 10°1
The inclination angle of 1 is 01. θ2, R1'cosθ+ R2'CO9θ2 R2'(R1'R2' ) cosθ2R+ < R
The relationship is o<R+'R2(R4<12').

Then, as shown in FIG. 6, a constant slope portion 10 on the outer peripheral side
Is flat 1 on the surface of circle ffJ with radius R? The sides AB and CD of the quadrilateral ABCD are made vertical and wound at a constant inclination angle θ1, and the constant inclination part 11 on the inner circumferential side also has a radius R2.
It has a shape in which a parallelogram is wrapped around the cylindrical surface at a constant inclination angle θ2.

As shown in FIG. 7, the upper curved part 12 on the outer peripheral side has sides A'B' of quadrilateral A'B'C″D' on the circular part surface of radius R3.
The side C'D' is made vertical, and the inclination angle is changed continuously from 01 to 0. Change it up to 0 to create a shape that is wrapped around a quadrilateral.
The lower curved portions 14 and 15 on the outer circumferential side and the inner circumferential side are also the above-mentioned upper curved portions 1.
It can be configured almost the same as 2.13. Above the outer circumferential side and the inner circumferential side,
The lower horizontal parts 16 and 17 have a rectangular shape wrapped around the cylindrical surface of radii R,', R2' with an inclination angle of 0, and both end natural parts 18 and 19 are flat panels.

In addition, in FIGS. 4 and 5, 20 and 21 are upper and lower floor plates, and 22 is a skirt guard.

The inner panel of the parapet according to the embodiment configured as described above has two types of intermediate constant slope parts io and ti including the inner circumferential side and outer circumferential side, and upper and lower curved parts 12, 13, 14, and 15. 4 types including inner circumferential side and outer circumferential side, upper and lower horizontal parts 113.17
is obtained by molding a plastic or plastic plate using a total of 8 types of press dies, including 2 types for the inner and outer periphery sides, and is economical because there are fewer types of press dies for molding. In addition, it is possible to obtain a parapet inner panel that is suitable for the curved escalator that has a conveyance path and a simple step drive mechanism as previously proposed by the applicant.

〔Effect of the invention〕

As explained above, the parapet inner panel according to the present invention has a constant slope in the middle, upper and lower curved parts where the slope angle changes,
and upper and lower horizontal parts, and each of these parts is
By configuring a part of the cylindrical surface with multiple types of different radii, it can be obtained with a small number of molds, and therefore has a constant slope in the middle, an upper part with a varying slope angle, a lower curved part and an upper part. This has the effect of being able to provide at a low cost a curved escalator that is compatible with a curved escalator having a conveyance path with a different radius of curvature at the lower horizontal portion.
