Two sets of a movable handrail 51b corresponding to the acceleration / deceleration area and a movable handrail 51c corresponding to the high-speed area are provided on each side, and each movable handrail 51b, 51c has substantially the same speed as the speed of the pallets 50 in both corresponding areas. It is controlled to run at.

[0005] Each of the movable handrails 51b and 51c is formed in an endless shape and continuously circulates and travels. A substantially V-shaped empty space is provided between the movable handrails 51b and 51c having different traveling speeds. it can. For this reason, a support 59 is erected from the frame 57 in the air space between them, and a fixed handrail 61 fixed on the support 59 is provided to provide continuity between the movable handrails 51b and 51c. The movable handrails 51b, 5 adjacent to the fixed handrail 61 in the front and rear directions.
Since 1c always rotates and moves, it is necessary to form a slight gap S between adjacent surfaces. Since the surface of both handrails is substantially flat, the gap S is formed over the entire width of the handrail in the width direction.

FIG. 10 is an explanatory view of another example of a handrail device for a variable-speed passenger conveyor, which is disclosed in Japanese Patent Application Laid-Open No. 50-26277. FIG. 10 shows a handrail device applied to a conveyor device that accelerates and decelerates the conveying speed while curving the tread plate 71 in a horizontal plane and conveys the intermediate plate at a high speed, and each of the handrail devices 72a, b, 73a, and b. ,

[0007]

In the case of the movable handrail shown in FIGS. 7 to 9, in the transfer between the handrails, the passenger must once release his / her hand from the handrail that has been grasped and move on to the next handrail. In addition, there are areas where passengers are troublesome and lack comfort, and there are areas where handrails can not be grasped,
There is a problem that comfort and safety are impaired. Also,
There is also a problem that the passenger's comfort is impaired due to a sudden change in speed when changing the handrail. Furthermore, if the passenger does not release his hand during the transfer, there is a risk of collision with the fixed handrail, and there is a risk of fingers being caught in the gap between the handrail and the fixed handrail, which also lacks safety. There was a problem.

In the device disclosed in Japanese Patent Laid-Open Publication No. Sho 50-26277, since a part of the handrail device is arranged so as to overlap at the border of the handrail device, at least one of the handrail devices has a transfer path. The railing is not parallel to the treads, and the handrail position is changed in the lateral direction as viewed from the passenger, and there is a problem that passenger comfort and safety are impaired. In addition, there is a problem that a sudden change in speed occurs when the handrail is changed, and passenger comfort is impaired.

[0016]

FIG. 1 is a plan view of a variable speed moving sidewalk to which an embodiment of the present invention is applied. FIG. 2 is an enlarged view of a portion A surrounded by a square in FIG. 3 is a cross-sectional view taken along the line CC in FIG. 1, and FIG. 4 is an enlarged view of a portion B surrounded by a square in FIG. Hereinafter, the present embodiment will be described with reference to FIGS.

As shown in the figure, the moving sidewalk has three regions: a low speed region, an acceleration / deceleration region, and a high speed region. In the drawing, reference numeral 1 denotes a tread portion comprising a plurality of pallets, and a main tread portion 1a and a telescopic tread portion 1b arranged between the main tread portions 1a and extending and contracting (portions shown in black in the drawing).
It is composed of

Reference numerals 3a, 3b, and 3c denote handrail belts of a movable handrail device provided separately on both sides of a sidewalk in a low-speed area, an acceleration / deceleration area, and a high-speed area. As shown in FIG. 3, these handrail belts 3a, 3b, 3c are formed endlessly with arc portions at both ends, and are configured to run independently and circulate independently. The speed is set to be the same as that of the tread in each area, or approximately the average speed of the area. Reference numerals 5, 7, 9, and 11 denote auxiliary handrails installed between the low-speed area and the acceleration / deceleration area, and between the acceleration / deceleration area and the high-speed area.

Here, the configuration of the auxiliary handrails 5, 7, 9, 11 will be described with reference to FIGS. The auxiliary handrail 5 is installed at the joint between the handrail belt 3a and the handrail belt 3b, and the handrail belt 3
The intermediate speed belts 5a and 5b are provided on both side surfaces of the belts 3a and 3b so as to partially overlap the handrail belts 3a and 3b when viewed from the side.

The handrail belts 3a and 3b and the intermediate speed belt 5
The gap between a and 5b is set to be larger than the thickness of the finger, so that there is no danger of the passenger's finger being pinched at the overlapping part of the handrails. Also, the intermediate speed belt 5
The transport speeds of a and 5b are set to be intermediate between the speeds of the handrail belts 3a and 3b before and after straddling. For this reason,
Since the intermediate speed belts 5a and 5b act so as to alleviate a sudden change in speed at the time of connection, comfort is not impaired at the time of connection. Further, the intermediate speed belts 5a and 5b are provided so as to partially overlap the handrail belts 3a and 3b when viewed from the side, so that passengers can transfer without substantially releasing their hands from the handrails, which is also comfortable. Does not impair the performance.

2 and 4, reference numeral 15 denotes an auxiliary handrail 5;
This is a brush that is installed in a layered manner without gaps between the handrail and the movable handrail, and between the joints of the movable handrail. The brush 15 is installed so that the fiber extends in a direction perpendicular to the traveling direction of the handrail belt. By providing the brush 15, when the passenger comes to the transit part, his hand touches the brush, so that the passenger can be alerted to the transit part, which is safe. The brush is
As shown in FIG. 4, it is provided along the handrail belts 3a, 3b, and when a passenger forgets to release the handrail belts 3a, 3b, the hand always touches and the alerting power is high. .

In FIG. 4, reference numeral 17 denotes a shielding plate provided below the brush 15 at the boundary between the movable handrails.
It has a function to catch this.

Next, the operation of the present embodiment configured as described above will be described. The passenger gets on the tread 1 in the low-speed area from the entrance and gets caught by the handrail belt 3a. Then, when approaching the acceleration / deceleration area, the hand placed on the handrail belt 3a touches the intermediate speed belt 5a or 5b and is naturally grasped by this. Thereafter, when the vehicle enters the acceleration / deceleration region, it touches the handrail belt 3b and can move on naturally. In this transfer, the speed of the handrail belt gradually increases in the order of the handrail belt 3a, the intermediate speed belts 5a and 5b, and the handrail belt 3b. Absent. In addition, since the passenger hardly releases his hand from the handrail, he can transfer safely.

Further, even if the passenger forgets to release his hand from the handrail belt 3a at the time of connection, the handrail belt 3a will descend as it approaches the boundary, and the area around the wrist will move to the intermediate speed belt 5b. As a result, the passenger can naturally transfer to the intermediate speed belt 5b. Furthermore, even when the passenger does not notice, touching the brush 15 with his / her hand draws attention and notices the connection.

FIG. 5 shows the auxiliary handrail of the present invention in the low speed range.
It is explanatory drawing of the example applied to the boundary part between the discontinuous handrail 21 installed in the acceleration / deceleration area | region and the handrail device 23 by the endless belt in the high speed area | region. The discontinuous handrails 21 are provided with a plurality of discontinuous handrails corresponding to each stepping board whose transport speed changes, and synchronize the speed of each handrail with the stepping board.

As shown in FIG. 5, the auxiliary handrail of the present invention can be installed between completely different types of handrail devices, such as a discontinuous handrail and an endless belt type movable handrail. High in nature. In particular, in the case of the above example, the discontinuous handrail is expensive, while the endless belt-type movable handrail is inexpensive, so the use of the auxiliary handrail of the present invention can reduce the discontinuous handrail portion. This has the effect that the cost can be reduced as a whole.

FIG. 6 is an explanatory view of an example in which the auxiliary handrail according to the present invention is applied to a sidewalk that moves flexibly. In such a curved moving sidewalk, the tread speed in the curved area is fast outside the bend and slow inside, so that the speed of each of the divided handrails is set correspondingly to the tread speed. You. Therefore, the speed of the handrail belt of the movable handrail in FIG.
5a, 25b, 29a, V ₁ a rate of 29 b, V ₂ the speed of the outer handrail belt 27a of the curve area, if the speed of the inner curve region of the handrail belt 27b and V _3, V ₃
<V ₁ <V ₂

Therefore, the speed of the auxiliary handrail 5a arranged outside is V _5a , and the speed of the auxiliary handrail _5b arranged inside is V _5b.
Assuming that the speed V _5a and the speed V _5b are V ₁ <V _5a <
Set to be relationship V ₂ and _{V 3 <V 5b <V 1} . By setting in this way, the speed of the inside and outside handrails can be gradually changed at the connecting part between the straight area and the curved area, and a sudden change in speed at the time of transfer is eased, and passenger comfort is reduced Does not impair.

As described above, the auxiliary handrail of the present invention can be installed at each connecting portion of each handrail device, and can be set at an intermediate speed between the speeds of the front and rear handrail belts at each connecting portion.
It is possible to respond to the speed finely and to minimize the loss of comfort when connecting.

[0030]

As described above, the present invention has the following effects.

Since the auxiliary handrail device is arranged in the discontinuous portion between the handrails so as to straddle between the handrails adjacent to each other, the passenger always grips the handrail between the handrails having different speeds. In addition, speed fluctuations between handrails can be reduced, so that passengers can be transported more safely and comfortably. In addition, by providing the auxiliary handrail device, each of the divided handrail devices can be linearly arranged in the transport direction, so that the handrail position does not change laterally from the viewpoint of passengers, and passenger comfort and safety are improved. It is not spoiled.

Further, since the auxiliary handrail device is arranged on the side of the transporting path of the divided handrail device, the passenger's hand can naturally transfer to the auxiliary handrail device when coming to the transfer section.

Since the auxiliary handrail device is arranged on the side of the conveying path and outside of the divided handrail device, the transfer operation can be performed smoothly even at various hand positions of the passenger with respect to the handrail immediately before the auxiliary handrail device. . In addition, even when the passenger places the luggage on the handrail, the luggage can be smoothly transported.

Since the conveying speed of the auxiliary handrail device is set to an intermediate speed between the divided handrail devices, a sudden change in speed between the front and rear handrails can be reduced, and passengers can comfortably change when connecting handrails. Does not impair the performance.

Since the gap between the auxiliary handrail device and the separately arranged handrail device is set to be larger than the thickness of the finger, there is no danger of the passenger's finger being pinched between the two handrail devices, and the safety is ensured.

Since the brushes are arranged between the auxiliary handrail device and the handrail divided and arranged, and between the handrails divided and arranged, the passengers can be alerted at the connecting timing, and the safety is further improved.
