DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving handrail device for a man-conveyor, and more particularly to a moving handrail device for a rack-driven man-conveyor that transmits driving force by providing rack teeth on the inner surface of the moving handrail. .

[0002]

2. Description of the Related Art FIG.
BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic block diagram which shows the same conventional man conveyor as what was shown by Unexamined-Japanese-Patent No. 1 and No. 59-192084. In the figure, 1 is a main frame, 2 is a step, 3 is a balustrade standing on both sides of the step 2 on the main frame 1, and 4 is a moving handrail provided on the balustrade 3 and moved in synchronization with the step 2. .

[0005] 5 is installed at the upper end of the main frame 1 and
Is a handrail driving device that is connected to the driving device 5 via chains 7 and 8 and drives the moving handrail 4. The handrail driving device 6 moves between a driving roller and a pressure roller. The handrail 4 is pressed to frictionally drive the moving handrail 4.

The conventional friction drive type handrail drive device 6 as described above has the following disadvantages. That is, when the man conveyor becomes a long machine, a slight slip occurs between the moving handrail 4 and the drive roller, so that a speed error is likely to occur,
A shift occurs between the moving handrail 4 and the step 2. Further, a large driving force cannot be obtained due to friction driving, and a plurality of handrail driving devices 6 need to be installed at a high head. Further, the speed of the moving handrail 4 is slightly changed due to the influence of rainwater, garbage, etc., and passenger load fluctuation. Furthermore, a slip occurs due to an abnormal external force applied to the moving handrail 4. Further, since a large pressing force is required by the pressure roller, the surface (on the side of the decorative rubber) of the moving handrail 4 is likely to be deteriorated or stained.

[0005] With respect to the friction drive type handrail drive device 6 having these drawbacks, as shown in, for example, Japanese Patent Laid-Open No. 4-32491, a handrail-side rack tooth is provided on the inner surface of a moving handrail to drive with a gear. A rack-type driving method in which wheels are combined to obtain a large driving force without causing a slip has been proposed.

[0006]

However, in the conventional rack-type driving method, since the number of rack teeth of the moving handrail that can mesh with the driving wheel with gears is one or two, a large driving force will be transmitted. Or, if an abnormal external force acts on the moving handrail, a large force acts on these one or two teeth,
There is a problem that the rack teeth may be damaged.
On the other hand, the rack teeth of the moving handrail need to be made of a flexible and stretchable material such as rubber, plastic, or a cloth laminate so as to be able to cope with the bending of the moving handrail. Have difficulty.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to eliminate the drawbacks of the friction drive system and prevent the handrail-side rack teeth from being damaged.

Both of them rotate together with no slippage, and power is transmitted. Therefore, the point that the speed of the moving handrail 11 can be matched with that of the step 2 is the same as that of the first and second embodiments. No deviation occurs.

However, when a torque equal to or larger than the set torque value is generated (when an abnormal external force is generated), a slip occurs between the first sprocket 21 and the second sprocket 22 and an abnormal external force is generated. Transmission is blocked. That is, in the rack-driven moving handrail device, if the moving handrail 11 is locked for any reason, the chains 14, 15 are locked.

By providing such a belt guide 31, it is possible to prevent the belt 16 from floating from the moving handrail 11 regardless of the installation position of the moving handrail device.
Accurate power transmission can be maintained. In addition, by providing the rotating roller 32 on the surface side of the moving handrail 11,
The above-mentioned lifting is more reliably prevented.

The belt guide 31 and the rotating roller 3
No. 2 only needs to be in contact with the belt 16 and the moving handrail 11 and does not need to be pressed strongly like a friction drive roller or a pressure roller. Absent. Further, the belt guide 31 and the rotating roller 32 can be set so as not to normally contact the belt 16 and the moving handrail 11.
