Furthermore, even during rush hours, speeds of up to about 40 m/min are allowed at most for the same reason as above. Therefore, in order to respond to the need for mass transportation due to population growth and transportation equipment that will inevitably become longer distances as we head into the era of deep underground use, it is necessary to transport people safely and quickly to their destinations in a small amount of dedicated space. In order to meet these demands, transportation means that can transport people up to In order to allow passengers to get on and off the vehicle without giving a shock due to the speed difference, a continuous transportation device has been proposed that is equipped with a transfer coupling device that has a speed change function that reduces the relative speed difference in stages.

The same applies when the main body escalator is a main body moving walkway.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the drawings.

1 to 3 show embodiments of the present invention,
The variable speed escalator unit 10 shown in FIG. 1 has a movable walkway 30 provided near the boarding and alighting section of the escalator main body 11 via connecting devices 20 each having a transportation function.

In addition, the main escalator 11 and the moving walkway 30 include:
We are using what is currently in use.

The coupling device 20 is provided with a plurality of rollers 22 forming a transport section 21 of the coupling device 20 via bearings such as bellows (not shown) on a pedestal (not shown), and an idler 22a.
and 22b eliminate the inconvenience caused by the arcuate ends of the transport section of the main escalator 11 and the moving walkway 30.

Handrails 23 are provided on both sides of the transport section 21 in the same way as the main escalator 11 and the moving walkway 30.

A plurality of rollers 22 are provided in parallel without contacting each other so that the longitudinal direction is in the width direction with respect to the traveling direction of the main escalator 11 and is located on the same plane as the transportation part surface of the main escalator 11 and the moving walkway 30. A shaft 24 is formed on both end surfaces of the roller 220 to be pivotally supported by the aforementioned bearings (not shown).
The power from the provided drive device 25 is transmitted to the chains 26a~
Sprockets 27-45 are provided for transmission at 26j.

In addition, the roller 22 surface is subject to slippage during the transportation of personnel.

Appropriate unevenness 22c is formed to prevent this.

Note that the roller 22 and idlers 22a, 22b are
Although it depends on the processing accuracy, it is preferable to provide them at the minimum possible intervals. Further, in this embodiment, the roller 22 is formed in a cylindrical shape, but it is not necessarily limited to this. For example, a polygonal prism whose longitudinal cross-sectional shape is octagonal or decagonal may be used.

The structure of the handrail 23 constituting the connecting device 20 is almost the same as that of the main escalator 11 or the moving walkway 30, but it needs to be designed in consideration of the size of the connecting device.

Further, the handrail 23 is connected to the drive unit W2 of the coupling device 20.
When s is driven, this power is transmitted from the drive device 25 to the sprocket 27 via the chain 26a, and the sprocket 42 and chain 43 drive the handrail 23! 23b to drive it.

Furthermore, a connecting member 50 is provided between the handrail 23 of the connecting device 20 and the handrail of the main escalator 11 or the moving walkway 30 to connect them.

The connecting member 50 is designed to close a gap caused by the shapes of the end portions of the handrail 23 of the coupling device 20 and the handrail of the main escalator 11 or the moving walkway 30, that is, the end portions are formed in an arc shape. Both sides of the handrail main body 23a are covered with covers 51, and rollers 52 are conveniently provided on approximately the same surface as the upper surface of these handrails. The roller 52 allows the handrail 23 of the coupling device 20 to be smoothly connected to the handrail of the main escalator 11 or the moving walkway 30.

Next, the action will be explained.

The coupling device 20 is driven by the drive device 25, so that
Power is transmitted from this drive device 25 to a sprocket 27 via a chain 26a, and this power is sequentially transmitted from a sprocket 28 provided close to the sprocket 27 to a sprocket 29 via a chain 26b. sprocket 31 via chain 26c from sprocket 30 provided close to
transmitted to. In this way, the power from the drive device 25 is transmitted to the chains 26a to 26j and the sprockets 27 to 4.
A plurality of rollers 22 (
In this embodiment, the signal is transmitted to 10 rollers 22 having the same diameter, and these rollers 22 rotate at the same speed and in the same direction.

Also, a chain 43 is connected to a sprocket 42 provided on the shaft 24 of the roller 22 having sprockets 27 and 28.
The handrail 23 constituting the coupling device 20 is driven by the power transmitted through the transport section 21 in the same traveling direction and moving speed.

In addition, a plurality of rollers 22, shafts 24, sprockets 27
~45 and coupling devices 2 such as chains 26a~26j
The parts constituting 0 need to be designed in consideration of the load during use and the above conditions.

Next, the main body escalator 11 is connected to the connecting device 20 shown above.
In this embodiment, the moving speed of the main escalator 11 is 50 m/min, the moving speed of the connecting device W20 is 40 m/min, and the moving speed of the moving pavement 30 is 30 m/min. Take for example the case where

In this case, the speed difference when getting onto the moving pavement 30 from the stop position is naturally 30 m/min, but from the moving pavement 30 to the connecting device 20 and from the connecting device 20 to the main escalator 11.
Since the speed difference when transferring to the moving pavement 30 is 10 m/min, the impact due to these speed differences is greatest when transferring from the stopped position to the moving pavement 30. Moreover, this speed difference of 30 m/min.
m/min is the same as the limit for escalators and moving pavements currently in use. Therefore, by setting these speeds within the desired and permissible range, it becomes possible to transport personnel to the destination in a short time with less impact due to speed differences.

Further, in this embodiment, there is one main body escalator 11, but instead of this, a plurality of main body escalators 11 having stepwise speed differences are provided as shown in FIG. 4, and two main body escalators 11 belonging to these different speed systems are provided. By providing a connecting device 20 that connects locations so that people can be transported with a stepwise change in speed that monotonically increases or decreases, it is possible to transport people safely and quickly to their destinations with a small amount of dedicated space, which can help with population growth. This variable speed escalator is simple and highly economical, and can respond to the need for mass transportation due to the development of large-scale transportation systems, etc., and transportation equipment that will inevitably become longer distances as we move toward the age of deep underground use.

Although the present invention has been described in detail above, the present invention does not necessarily need to be limited to this. For example, the drive mechanism, etc.
Any mechanism such as a gear mechanism or a belt transmission mechanism may be used as long as it satisfies the above conditions, and it is not necessary to drive all of the rollers 22 that constitute the transport section 21 of the coupling device 20. Furthermore, the roller 22
It is also possible to use ones with different diameters.

Note that if a main body moving walkway is used instead of the main body escalator, the structure, operation, and effect are almost the same, so the description will be omitted.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to transport people safely and quickly to a destination in a small amount of exclusive space, and it is suitable for the need for mass transportation due to population growth and the era of deep underground use. The present invention provides a variable speed escalator and moving walkway system that is simple and economical, and can accommodate transportation devices that will inevitably become longer distances.
