Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail device for use in intermediate-high speed passenger conveyors in which the steps are faster in the middle of the conveyor travel than at the ends.

Recent passenger conveyors tend to have longer conveyance distances, and in this case, it takes a long time for passengers to get on the conveyor and get off the conveyor. Therefore, it is necessary to improve the service by shortening the time that passengers spend on the conveyor. For this reason, as a passenger conveyor, it is driven at a slow speed near the entrance so that passengers can board safely, gradually accelerates as it approaches the middle part, and moves at a constant high speed in the middle part.
An intermediate-high speed type has been proposed, in which the train gradually decelerates as it approaches the exit, and operates at a slower speed near the exit so that passengers can get off safely.

In addition, as mentioned above, the longer medium-high-speed passenger conveyor is not necessarily straight due to the layout of the building or the topography, and may have a horizontally curved part near the entrance or in the middle. be.

However, in the above-described intermediate high-speed passenger conveyor having a horizontally curved section, the moving speed of the intermediate high-speed step and the left and right handrails in the curved section, especially the left handrail and right handrail, is affected. This created a problem in that it was difficult to grasp these moving handrails and transport passengers safely.

This invention has been made to solve the above-mentioned problems, and in an intermediate high-speed passenger conveyor having a horizontally curved section, in the curved section, the central part of the intermediate step in the left-right (width) direction is To provide a handrail device for a passenger conveyor, in which moving handrails of left and right handrails are respectively moved with the same angular velocity as the angular velocity, and passengers can be safely conveyed by grasping the handrail pieces of these moving handrails.

In the linear intermediate section 4 of the passenger conveyor 1, the outer and inner rails 13, 1 are driven in the direction of the arrow a in the figure.
4 is narrow, so the upper and lower links 20, 2
1 moves in a wide-angle V-shape, and the handrail piece 17 is driven at the same high speed as the intermediate high speed step 6. In addition, in the curved section 3 of the passenger conveyor 1, the intermediate high speed step 6 is gradually decelerated along an arc with a radius of curvature Rc at its center, and at the left side handrail 11 on the outside, the intermediate high speed step 6 has a radius of curvature Ro. Along the circular arc, on the inner right side handrail 12, the handrail pieces 17 are moved along an arc having a radius of curvature Ri smaller than the radius of curvature Rc of the intermediate high speed step 6. In this case, the left and right handrails 11,
Curved portion 13 of outer and inner rails 13 and 14 of 12
The intervals between c and 14c are appropriately set in the reverse curved portions 13b and 14.
Since the handrail pieces 17 of the left and right handrails 11 and 12 gradually become wider toward the direction b, the V-shaped angles of the upper and lower links 20 and 21 become narrower, and the handrail pieces 17 of the left and right handrails 11 and 12 are narrower, while the V-shaped angles of the upper and lower links 20 and 21 become narrower. is moved with the same angular velocity as the angular velocity. Further, in the second part of the entrance/exit, the handrail pieces 17 of the left and right handrails 11 and 12 are decelerated to the same low speed as the speed of the intermediate high speed step 6,

14b, the angle of the V-shape of the upper and lower links 20, 21 becomes the narrowest at these parts, and the handrail piece 17 moves at a predetermined low speed. Then, the handrail pieces 17 of the left and right handrails 11 and 12 are on the outside,
Inverted curved portions 13b, 14b of inner rails 13, 14
When moving toward the intermediate portions 13a, 14a from
After passing through b, the speed gradually increases, and the intermediate part 13a, 1
4a, the handrail piece 17 moves at a predetermined high speed, and in this case as well, the handrail piece 17 moves in response to the speed change in the intermediate high speed step 6.

Therefore, in the handrail device of this embodiment, if a passenger who gets on the intermediate high speed step 6 at the entrance/exit 2 holds the nearby handrail piece 17, there is no need to change the grip on the handrail piece 17 until the passenger gets off, and the passenger is safe.

In the above embodiment, a passenger conveyor having a curved part near the entrance/exit has been described, but the present invention can also be applied to a passenger conveyor which has a curved part in the middle part and decelerates at this curved part as necessary. In substantially the same way as in the embodiment described above, the moving handrails on the left and right handrails can be driven at the same angular velocity as the angular velocity at the center in the left-right direction of the intermediate high-speed step.

As explained above, the present invention provides an intermediate high-speed passenger conveyor having a horizontally curved portion 3, with left and right handrails 7 and 8 provided on both sides along the longitudinal direction of the passenger conveyor, so that the longitudinal direction of these handrails is an outer rail 13 that is provided endlessly along the direction and has an inverted curved portion 13b in the horizontal direction at the end of the handrail;
and an inverted curved part 14 in the horizontal direction that is provided in an endless manner on the inner peripheral side of the outer rail 13 along the longitudinal direction of the handrail and is farthest from the inverted curved part 13b of the outer rail 13.
