Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tread which moves at a low speed in a boarding section, then gradually becomes a high speed, moves at a maximum speed in an intermediate section, and becomes gradually slower as it approaches an exit,
The present invention relates to a handrail device provided on both left and right sides of a variable speed type moving sidewalk, which moves at a low speed in the descending section similarly to the boarding section.

[0002]

2. Description of the Related Art In a variable speed moving walkway, it is not practical to change the speed of a moving handrail in synchronism with the changing speed of a tread because the mechanism is complicated. Therefore,
Generally, the moving handrail is divided into a plurality of pieces, which are arranged in series, and the operation is performed at a speed close to the speed of the tread in the vicinity of each.

In such a variable speed type handrail device for a moving sidewalk, it is extremely important for safety that the user smoothly replaces his / her hand between adjacent moving handrails. A device shown in FIG. 2 such as 101662 has been proposed.

That is, cleats 1a,
A member having a special shape different from the ordinary one having 2a is used, and a guide plate 4 is arranged on the connecting portion 3, and the guide plate 4 is provided.
Balls 5 are rotatably scattered to guide passengers' hands.

[0005]

However, in such a handrail device, since the moving handrails 1 and 2 themselves have a special shape, not only the cost is extremely high, but also the guide plate 4 is provided.
Is provided at a position considerably lower than the height of the upper surfaces of the moving handrails 1 and 2, the user's hand drops from the height of the moving handrails 1 and 2 to the height of the guide plate 4 at a stretch, and the moving handrail transfer section 3
Users who were not aware of were surprised and could lose their position. Then, the moving handrail 1 or 2 ahead of the guide plate 4
There is a risk of colliding with the moving handrail 2 or 1 when the hand is replaced.

[0006] Also, although freely rotating balls 5 are arranged on the upper surface of the guide plate 4, when a hand is placed on such a freely rotating ball 5, the hand moves in a direction different from the moving direction of the body. There was also a problem that the posture was not stable due to slipping.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a safer variable speed type handrail device for a moving walkway.

[0008]

SUMMARY OF THE INVENTION The present invention is a variable speed moving walkway that is carried by a user on a tread whose speed changes, and is set up on both sides of the tread at a speed close to that of the tread. In the one with multiple independent moving handrails that move,
The moving handrail transfer section is provided with a plurality of rotating bodies whose rotation axis direction is perpendicular to the moving handrail operation direction.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a handrail device for a moving sidewalk of a variable speed type, rotatably provided with a roller having a function of assisting smooth replacement of a user's hand between a plurality of moving handrails. It is a thing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is an overall view of a handrail device showing an embodiment of the present invention, FIG. 3 is a plan view of FIG. 1, and FIG. 4 is a view taken along the line AA of FIG.

In the figure, 8 and 9 are normal moving handrails, and 11, 1
Reference numeral 2 denotes a guide roller according to the present invention. A plurality of guide rollers having a substantially uniform diameter are arranged in the traveling direction, and are rotatably provided by another independent mechanism described later. The guide rollers 11 and 12 are provided with cut grooves 11a and 12a to prevent the plate 1 from moving unnecessarily in the left-right direction.
It is supported and guided by 3.

A plurality of support rollers 14 are arranged below the guide roller 11 and are inserted between the plates 13. Reference numeral 15 is a circulation belt that passes between the guide roller 11 and the support roller 14. The support roller 14 presses the circulation belt 15 against the lower portion of the guide roller 11, and the driving force of the circulation belt 15 is transmitted to the guide roller 11. Is configured. Reference numeral 16 is a roller for driving the circulation belt 15, and a tension roller 17 applies an appropriate tension to the circulation belt 15. The roller 16
The driving source of the motor is a moving handrail or a separately provided motor 18.
Etc.

Reference numeral 20 denotes a driven roller which is always in contact with the moving handrails 8 and 9 and is driven, and is arranged in front of and behind the support roller 14. Then, the guide roller 1 facing the moving handrails 8 and 9
Reference numeral 2 is in contact with the driven roller 20 and has a structure in which a driving force is obtained from the driven roller 20.

Here, the peripheral speed of the guide rollers 11 can be arbitrarily selected by determining the moving speed of the circulation belt 15, and the peripheral speeds of all the guide rollers 11 are uniform in mechanism. If the driving method of the mechanism in which the rotation speed of 11 can be changed, the peripheral speed can be changed depending on the rotation speed and diameter of each guide roller 11.
The peripheral speed of the guide roller 11 is the same as or slower than the slower speed of the moving handrail before and after the connecting portion, or the same as or lower than the faster speed of the moving handrail before and after the connecting portion. Is set to.

Regarding the guide roller 12, in the drive mechanism as shown in FIG. 1, the moving speed of the moving handrails 8, 9 is the same as the moving speed of the moving handrails 8, 9 with which the driven roller 20 contacts.
It is also possible to set the optimum speed corresponding to the moving handrails 8 and 9 by using an independent drive mechanism that does not depend on the moving speed of the moving handrails 9. As with the guide roller 11, the peripheral speed of the guide roller 12 is equal to or higher than the speed of the slower moving handrail before and after the connecting portion, or the speed of the faster moving handrail before and after the connecting portion. Set to be the same or slower.

Since the driving sources of the guide rollers 11 and 12 are different from each other, the guide rollers 11 and 12 can be set to have a finer speed, such as different circumferential speeds.
It is possible to set the optimum speed corresponding to the speed of 9.

Regarding the layout of the guide rollers 11 and 12, for example, as shown in FIG. 5, the height is gradually changed, the diameter is changed, and the peripheral speed is variously changed by a driving mechanism. can do.

Next, FIG. 6 shows a second embodiment, in which the same parts as those in FIGS. 1 to 5 show the same parts.
A guide roller 32 is narrower in width than the moving handrails 8 and 9, and its movement in the width direction is restricted by the plate 13 as described above. Guides 33 are provided on both sides of the guide rollers 31 and 32. Various types shown in FIG. 7 can be considered for the shape and layout of the guide 33.

Next, FIG. 8 is a view showing another embodiment, in which the guide rollers 41 and 42 are cleats and grooves, and the adjacent guide rollers 41 and 42 have cleats and grooves engaged with each other. It is something like this.

With such a structure, the moving handrails 8 and 9
And a guide roller 11 facing the center.
Since and can be set to different speeds and the shape and material of the guide portion can be changed as appropriate, there is an advantage that a wide range of design choices can be taken.

In the above description, the guide roller is driven by the belt mechanism, but another driving mechanism may be used. In addition, about this variable speed type moving walkway,
Not only when the speed of the tread gradually changes to a variable speed,
Needless to say, it may be a variable speed type moving sidewalk in which belts having different speeds are arranged in series to gradually change the speed.

[0022]

As described above, according to the present invention,
The rotatable rollers act to help the user's hands to be replaced smoothly, so that the user can use the safe moving sidewalk.
