Abstract

PURPOSE:To reduce the travel loss of the movable handrail of a man-conveyer. CONSTITUTION:A return side movable handrail guide is tilted to satisfy the condition of theta2=theta3 < theta1, where theta1: the tilt angle of a landingattached escalator, and theta2 and theta3: bent angles on the lower and upper step sides of the return side movable handrail guide in a landing 1D respectively. Consequently the travel loss of a movable handrail can be sharply reduced.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor device such as an escalator, and more particularly to an improvement in a handrail guide on the return side of an escalator with a landing.

0002

[Prior Art] Figure 2 shows a conventional passenger conveyor system. In the figure, 1 is the main frame of an escalator with a landing, and this main frame has an upper machine room 1A installed on the upper floor and an upper machine room 1A installed on the lower floor. It comprises a lower machine room 1B installed, an inclined part 1C installed at an angle between the machine room 1A and the lower machine room 1B, and a landing 1D provided horizontally in the center of this inclined part 1C. It is composed of Furthermore, on both sides of the main frame 1, there are balustrades 2 that follow the shape of the main frame 1, and on this balustrade 2,
An endless moving handrail 3 is slidably wound around. Further, a drive gear 5 that rotates based on the drive of the drive machine 4 is disposed in the upper machine room 1A, and a follower gear 6 is disposed in the lower machine room 1B.

Reference numeral 7 denotes a step, and a plurality of steps 7 are connected in an endless manner in the internal longitudinal direction of the main frame 1, and a drive gear 5 and a follower gear 6 are wound around the front wheel axle (not shown). The step chains 8 are connected.

Reference numeral 9 denotes a handrail drive device disposed on both sides of the interior of the inclined portion 1C near the upper machine room 1A. 10 and the lower surface (surface) of the moving handrail 3 on the return side
a plurality of lower rollers 11 pressed against the drive machine 2;
It has a function of moving the handrail 3 in a circular manner by operating based on the drive of the handrail 3. The return-side moving handrail 3 is guided by return-side moving handrail guides (not shown) disposed on both sides of the main frame 1 to circulate.

On the other hand, θ1 is the inclination angle of the escalator with a landing, θ2 is the bending angle of the lower floor side of the return side moving handrail guide (not shown) that guides the return side moving handrail 3 at the landing 1D, and θ3 is the bending angle of the lower floor side of the landing 1D. This is the bending angle of the return side moving handrail guide on the upper floor side. And these θ1
~θ3 has the relationship θ1 = θ2 = θ3.

Therefore, when the driving machine 2 is driven, the step chain 8 circulates and moves toward the step 7 while being guided by the step rail.
The train circulates and transports passengers either upstairs or downstairs. Also,
Based on the drive of the drive machine 2, the handrail drive device 9 operates to circulately move the movable handrail 3.

[0007]

[Problems to be Solved by the Invention] The conventional passenger conveyor device is constructed as described above, and θ1 to θ3 are θ1 =
Because of the relationship θ2 = θ3, there was a problem in that the travel loss of the movable handrail 3 was large. The present invention has been made in view of the above, and an object of the present invention is to provide a passenger conveyor device that can reduce travel loss of a moving handrail.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, on the inclined part of the main frame of the escalator,
A landing is provided horizontally, and a return side moving handrail guide for guiding the return side moving handrail is arranged on the inside of this landing.
Moreover, if the inclination angle of the escalator is θ1, the bending angle of the lower floor side of the return side moving handrail guide at the landing is θ2, and the bending angle of the upper floor side of the return side moving handrail guide at the landing is θ3, then It is characterized in that the side moving handrail guide is inclined so that θ2 = θ3 < θ1.

[0009]

[Operation] According to the present invention, the return side moving handrail guide is tilted so that the bending angle of the lower floor side of the return side moving handrail guide at the landing = the upper floor side bending angle of the return side moving handrail guide at the landing < the landing Since the inclination angle of the escalator is set, the traveling loss of the moving handrail can be significantly reduced.

0010

[Example] Hereinafter, the present invention will be described in detail based on an example shown in FIG. 1. θ1 is the inclination angle of the escalator with a landing, and θ2 is the return side moving handrail guide that guides the return side moving handrail at the landing 1D. The bending angle θ3 on the lower floor side (not shown) is the bending angle on the upper floor side of the return side moving handrail guide at the landing 1D. And these θ1 ~ θ3
Due to the inclination of the return side moving handrail guide, θ2 = θ3
<θ1.

The other parts are the same as the conventional example.

Next, the effects of the present invention will be explained in detail in comparison with the conventional example, but the premise is that in FIG.

[Math 1] T'2 = T2 + R1

[Math 2] R=T1-T3.

[0013] The above T1, T2, T'2, T3 =
Tension μ acting on the return handrail 3 = frictional resistance R = running loss R1 = running loss between θ3 and θ2.

According to the conventional example, θ1 = θ2 = θ3
=π/6=0.523, whereas according to the present invention, θ2 =θ3 =25°=25°×π/180°=0
．． It becomes 44.

[0015] According to the above configuration, since the return side movable handrail guide is inclined to establish the relationship θ2=θ3 <θ1, it is possible to significantly reduce travel loss of the return side movable handrail 3.

[0016]

As described above, according to the present invention, the inclination angle of the escalator with a landing is θ1, the bending angle of the lower floor side of the return side moving handrail guide at the landing is θ2, and the bending angle of the return side moving handrail guide at the landing is θ2. The bending angle on the upper floor side is θ3
In this case, since the return side movable handrail guide is inclined so that θ2 = θ3 <θ1, it is possible to significantly reduce travel loss of the movable handrail. Further, there is an effect that wear of the movable handrail guide can be prevented.
