Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving handrail on a moving sidewalk that can safely and quickly transport passengers even during a relatively long journey.

[0002]

2. Description of the Related Art In the case of a moving sidewalk installed in a place such as an airport, for example, 30 m / min or 40 m / m
There was a problem that the passengers took too long to move because the speed was too slow on a normal moving sidewalk that was driven in.

Therefore, a new type of moving walkway that moves gently when passengers get on and off and moves at high speed in the middle is desired, but as shown in Japanese Patent Laid-Open No. 2-75594, the following movements are made. A sidewalk is proposed.

That is, FIG. 2 is a schematic view of a moving walkway composed of a plurality of endless circulation belts, and FIG. 3 is a partially enlarged view of FIG.

In the figure, reference numeral 2 is an independent module in which an endless sliding belt 20 which is thin and extremely flexible passes under a set of guide rollers 25 and is constantly driven by a driving roller 30 at a constant speed. Set the module 2 located at the low speed and the module 2'located far from the entrance / exit to the high speed gradually, and the passengers move to the adjacent modules 2, 2 ', 2', .... It is configured to gradually accelerate or decelerate each time.

Numeral 15 is arranged at both ends of each module 2 or 2 ', and has a diameter of 30 mm to 70 m, for example.
With an extremely small diameter roller of about m, the gap between the opposing small diameter rollers 15 is suppressed to a size of about 20 mm to 40 mm, which is smaller than that of a considerably small shoe such as a child's shoe.

Reference numeral 10 is an adjacent module 2 or 2 '.
Is a T-shaped carrier plate whose upper surface is positioned lower than the upper surface of the endless sliding belt 20 in the gap of each set, and is a member omitted when at least the circulation speed of the endless sliding belt is high.

Reference numeral 26 is a sliding plate for supporting and guiding the upper track of the endless sliding belt 20, and 27 is a long main circulation belt forming a central portion of a moving walkway which moves fastest in the vicinity of the high speed module 2 '.

[0009]

By the way, in the case of a moving walkway in which a plurality of modules 2 and 2'having different speeds are connected in the transport direction as described above, the passengers are guided for the safety of the transported passengers. How to install moving handrails remains a question.

The present invention has been made in view of the above points, and an object of the present invention is to provide a moving handrail that sufficiently functions even in the case of a variable speed type moving walkway of this type.

[0011]

SUMMARY OF THE INVENTION The present invention is directed to spaced first and second rollers, drive means, and over and above the first and second rollers. At least two modules with an endless belt driven by the longitudinal direction are arranged in series in the longitudinal direction, the endless belts of each module are circulated at different speeds, straddling the first endless belt and the second endless belt, In a moving sidewalk where the moving handrail is arranged on the side, the moving speed of the moving handrail is set to an arbitrary speed between the first endless belt and the second endless belt,
One point of the moving handrail is supported at the highest position or the lowest position different from one end.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is to guide a moving handrail so that the passengers can be provided with joints at their elbows and shoulders.

In the figure, 31 is a drive roller for the getting on and off belt 21,
32 is a drive roller for the first endless sliding belt 22, 33 is a drive roller for the second endless sliding belt 23, 34 is a drive roller for the third endless sliding belt 24, and 35 is a drive for the fourth endless sliding belt 25. Rollers 36 are drive rollers for the main circulation belt 27, and are driven by a single drive source via a drive chain 37 and the like.

FIG. 6 is a diagram showing a driving mechanism for the third and fourth endless sliding belts 24, 25 and the moving handrail 52. The opposite side portion corresponding to the P portion is also the same, Boarding / alighting belts 21, 21 'and first endless sliding belts 22,
22 'and third and fourth endless sliding belts 24, 2
In the case of 4 ', 25, and 25', since the same drive mechanism is used, detailed drawings are omitted.

Reference numeral 74 is a sprocket rotatably provided coaxially with the drive roller 34, and serves to transmit power to the moving handrail 52.

Numeral 80 is a well-known clamping pressure driving device which drives the moving handrail 52 by compressing it, which is composed of driving rollers 80a and 80b, driven rollers 80c and 80d, and sprockets 80e and 80f coaxial with the driving rollers 80a and 80b. The chain 80g for transmitting power is the sprockets 74, 80e, 8
It is wrapped around 0f.

The moving speed of the moving handrail 52 is increased with respect to the endless sliding belt 24 by appropriately determining the respective diameters of the roller and the sprocket.

Reference numeral 81 is a guide roller, and reference numeral 82 is a tension roller for adjusting the tension of the moving handrail. Since the drive mechanism for the moving handrail 50 is also the speed increasing mechanism similar to the above-mentioned case, detailed description thereof will be omitted.

Further, the driving method of the endless sliding belts 23, 23 ', the main circulation belt 27 and the moving handrails 51, 51', 53 is also the same, and it suffices to replace them with a constant velocity mechanism which does not increase the diameters of the rollers and the sprockets. Therefore, detailed description is omitted.

By the way, the above-mentioned structure is convenient because the circulating belt or the moving handrail at a required speed can be obtained very easily from a single drive source or a limited number of drive sources. Since advance guidance operation and delay guidance operation by the moving handrail are mixed with the movement by the circulation belt, it is desirable to make some adjustments.

That is, the upper surface of the moving handrail 52 straddling the endless sliding belt 24 and the endless sliding belt 25 at different speeds is shown in FIG.
As shown in FIG. 7, since passengers on the endless sliding belt 24 are guided and guided by the moving handrail 52 having a high speed in a flat case, as shown in FIG.
As shown in FIG. 7A, the state transitions to the state shown in FIG. 7B after a predetermined time has passed, and as a result, the moving handrail 52 may pull the body.

That is, at the beginning of riding, the passenger's shoulder joint point A, elbow joint point B, and palm point C (where the moving handrail is gripped)
As shown in FIG. 7A, the relationship of
As a result of the move handrail 52 moving, the points A, B, and C extend straight as shown in FIG. 7B, and the point A moves in the direction of the arrow, so that the body is pulled by the moving handrail 52. Will be done.

For this reason, it is also possible to incline the upper surface of the moving handrail as shown in FIG. 8, that is, to give a slope to the traveling direction of the sidewalk.

That is, the position of the upper surface of the moving handrail 52 facing the joint between the endless sliding belt 24 and the endless sliding belt 25 is raised so that the leading and lagging guiding operations of the moving handrail 52 are alleviated.

That is, as can be seen from FIG. 9, when the height of the moving handrail 52 (where the passengers are touching their hands) increases,
Despite the fact that the moving handrail is advancing with respect to the belt (advancing guidance operation), the angle formed by the line connecting points A and B and the perpendicular line passing through point A hardly changes, and point A- C
Since the point-to-point distance does not increase, it is possible to reduce the discomfort that the passenger pulls forward by the moving handrail.

Then, on the contrary, in a region where the moving handrail is delayed with respect to the belt (delay guiding operation), the moving handrail is guided to a downward slope to reduce the discomfort that the passenger is pulled backward this time. As in the case above, points A and B
Since the angle formed by the line connecting the points and the vertical line passing through the point A is hardly changed, it is possible to alleviate both the advance guidance operation and the lag guidance operation depending on how the moving handrail is inclined.

On the other hand, as for the method of guiding the moving handrail in the area where the passengers are decelerated, as shown by the broken line in FIG. 8, the upper surface position facing the joint between the endless sliding belts 24 'and 25' is lowered, It is desirable to configure so as to have a gradient opposite to that of the acceleration region.

In short, the present invention is applicable to the case where the moving speed of the carrier for guiding passengers is different from that of the moving handrail for guiding passengers.
By devising the guide means of the moving handrail, the leading guide operation and the delayed guiding operation by the moving handrail can be alleviated extremely effectively.

Therefore, the conveyor belt may be not only a belt but also a pallet, and is not particularly limited to a special one.

Further, in the embodiment, the case where the moving handrail is arranged across two belts having different speeds has been described in detail. However, as shown in FIG. Endless belts 60, 61, 62,
In contrast to 63, 64 and 65, the moving handrail 70 has an endless belt
The moving handrail 71 may be a moving walkway that is set at the same speed as that of the endless belt 65 and arranged at the same speed as the endless belt 65, and the present invention can be appropriately applied.

[0039]

As described above, according to the present invention, even with a moving handrail that moves at a speed different from the movement of the conveyor belt, there is little risk that the passenger will fall into an unstable state due to the guiding operation. You can get a moving walkway.
