Description

  The present invention relates to passenger conveyors such as escalators and moving sidewalks, and more particularly to a balustrade structure at an exit.

  In the conventional escalator, an escalator body configured in a hollow body is installed between an upper floor and a lower floor, and a step is locked to a pair of step chains wound between upper and lower step sprockets. An endless conveyor is arranged in the escalator body, and a pair of balustrades are erected in parallel with each other over the longitudinal direction of the escalator body at the upper left and right sides of the escalator body. A drive device such as a motor is disposed at the lower floor end in the escalator body, and rotates the step with the step chain via the step sprocket. Further, a moving handrail provided on the balustrade is driven to rotate in synchronization with the step (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 04-020497

In this type of escalator, the step is moving at a constant speed, which may be faster than the walking speed of a passenger with a disability or an elderly passenger.
However, in conventional escalators, a pair of balustrades are extended in the longitudinal direction of the escalator body in parallel with each other at regular intervals, so when a passenger with slow walking speed is walking on the floor board of the exit, There was a problem in that the exit portion was crowded because there was no place for the subsequent passengers to get on the steps and transported to the exit.

  The present invention has been made to solve the above-described problem. The distance between the pair of balustrades at the exit is a mouth-opening shape, and even if the speed of a passenger walking on the floor board of the exit is slow, the exit The purpose is to obtain a passenger conveyor that secures a space where the subsequent passengers who have been transported to can avoid the passengers and can eliminate congestion at the exit.

  A passenger conveyor according to the present invention includes a truss, a passenger entrance configured to close one end of the truss with a passenger floor board, and a passenger exit configured to close the other end of the truss with a passenger floor board. It is connected endlessly with the mouth, from the entrance floor board to the exit floor board, enters the truss from the entrance side end of the exit floor board, and enters the truss through the exit side inversion part. A plurality of steps that circulate along the circulation path that leads to the outside of the truss from the exit side end of the entrance floor plate through the entrance side reversing portion, and the plurality of steps. A pair of balustrades that are erected on the truss so as to face the width direction of the steps and extend from the entrance to the exit along the moving direction of the plurality of steps, and the pair of balustrades Guided by each of the balustrades, it is linked to the cyclic movement of the multiple steps. And a, a moving handrail endless circulated moved. The pair of balustrades are arranged in a range from the exit side end of the entrance floor board to the entrance side end of the exit floor board, with the intervals in the width direction of the plurality of steps being constant. Extending in parallel with each other in the direction of movement of the steps, and at the exit, the intervals in the width direction of the plurality of steps become wider as they move away from the entrance in the direction of movement of the plurality of steps. It is extended to.

  In this invention, the pair of balustrades are extended so that the distance in the width direction of the step at the exit is wide enough to move away from the entrance in the moving direction of the step. When a passenger who has reached the exit is grabbed by the moving handrail and changes to the exit floor, the passenger is guided in the moving direction of the moving handrail. Therefore, the passenger who has transferred to the exit floor board will walk so as to deviate outward in the width direction of the step with respect to the direction of movement of the subsequent passenger carried on the step. The walking space expands. Thereby, even if the passenger who has transferred to the exit floor board is walking slowly, the subsequent passenger can walk avoiding the passenger, and the congestion at the exit is eliminated.

It is a side view which shows typically the whole structure in the escalator which concerns on one embodiment of this invention. It is II-II arrow sectional drawing of FIG. It is a principal part top view which shows the downhole periphery in the escalator which concerns on one embodiment of this invention. It is sectional drawing explaining the structure of the curved part of the balustrade in the escalator which concerns on one embodiment of this invention.

  Hereinafter, a preferred embodiment of a passenger conveyor according to the present invention will be described with reference to the drawings.

FIG. 4 is a cross-sectional view illustrating the configuration of the curved portion of the balustrade in the escalator according to one embodiment of the present invention.

  In FIG. 1, an escalator 1 includes a truss 2 spanned between upper and lower floors, an electric motor 5 installed in an upper machine room 3 of the truss 2, and an electric machine 5 driven in the upper machine room 3. A drive sprocket 7 connected by a chain 6, an upper step sprocket 8 mounted coaxially with the drive sprocket 7, a lower step sprocket 9 installed in the lower machine chamber 4 of the truss 2, and an upper step sprocket 8 is fixed to an endless step chain 10 wound around the lower step sprocket 9 and a step shaft (not shown) attached to the step chain 10 at regular intervals, and is driven by an electric motor 5. A plurality of steps 11 that circulate between the upper and lower entrances 14 and 15, and the steps 11 that move on both sides of the step 11 on the forward path side of the steps 11 that circulate. A pair of balustrades 20 erected on the truss 2 so as to extend along the direction, and an endless moving balustrade that is guided and moved by the moving balustrade driving device 12 to the balustrade 20 at the same speed as the step 11 26 and a control panel 13 provided in the upper machine room 3 for controlling the driving of the electric motor 5.

  The upper entrance 14 is configured by installing a floor plate 16 on the truss 2 so as to close the upper machine room 3. The lower entrance / exit 15 is configured by installing a floor plate 17 on the truss 2 so as to close the lower machine room 4.

  The circulation path of the step 11 includes a forward section that travels between the floor plate 16 and the floor plate 17, an upper reversing portion that reverses the traveling direction at the lower portion of the floor plate 16, and a lower reversal that reverses the traveling direction at the lower portion of the floor plate 17. And a return side section that travels in the truss 2 between the upper reversing part and the lower reversing part. Here, if the step 11 moves from the lower entrance / exit 15 to the upper entrance / exit 14, the step 11 moves to the floor board 16 in the forward path side section, and the truss from the end of the floor board 16 on the lower entrance 15 side. 2, sinks into the upper part of the floor plate 17, the direction of movement is reversed via the upper reversal part, moves the return side section in the truss 2 to the lower part of the floor plate 17, and the direction of movement is reversed via the lower reversal part. It appears from the end on the entrance / exit 14 side and moves in the forward path section to the upper entrance / exit 14 side.

  Further, the forward side section of the step 11 includes an upper horizontal portion A reaching the upper entrance 14 and a lower horizontal portion B reaching the lower entrance 15 and an intermediate inclined portion between the upper horizontal portion A and the lower horizontal portion B. C. Therefore, a passenger who has entered the step 11 from the lower entrance / exit 15 reaches the intermediate inclined portion C via the lower horizontal portion B, is transported through the intermediate inclined portion C to the upper horizontal portion A, and then passes from the upper horizontal portion A to the upper portion. It gets off to the floor board 16 of the entrance / exit 14.

As shown in FIG. 2, the balustrade 20 is mounted on both sides of the step 11, on the balustrade columns 21 erected on the truss 2 at predetermined intervals in the moving direction of the step 11, and on the head of the balustrade column 21. A guide rail frame 22 extending between the upper entrance 14 and the lower entrance 15; an inner plate 23 attached to the guide rail frame 22 and defining the forward path side of the step 11; A guide rail 24 attached to the upper surface of the guide rail frame 22 and extending between the upper entrance 14 and the lower entrance 15 and a step between the steps 11 while maintaining a gap between the steps 11 A skirt guard (not shown) extending along the moving direction of the step 11 is provided.
The guide rail 24 has a pair of flange portions 25 projecting on both sides in the width direction of the balustrade 20 and extending in the moving direction of the step 11. A moving handrail 26 having a C-shaped cross section is attached to the guide rail 24 so that the flange portion 25 is accommodated in the ear portion 26a.

  As shown in FIG. 3, the balustrade 20 extends in parallel to each other with a constant distance between the balustrades 20 in the region of the upper horizontal portion A and the intermediate inclined portion C. In the region of the upper entrance 14, The distance between the balustrades 20 extends from the upper horizontal portion A through the curved portion 30 to the outside of the escalator 1 in the moving direction of the step 11, that is, in a mouth-opening shape that gradually spreads away from the lower entrance 15. It is installed. Although not shown, in the region of the lower horizontal portion B, the distance between the balustrades 20 is extended in parallel with each other. In the region of the lower entrance 15, the distance between the balustrades 20 is the lower horizontal portion. It extends from B toward the outside of the escalator 1 in the moving direction of the step 11 through the curved portion, that is, in a mouth-opening shape that gradually spreads away from the upper entrance 14.

  In the escalator 1 configured as described above, the passengers grab the moving handrail 26 from the floor plate 17 of the lower entrance 15 and move to the step 11 and ride on the step 11 from the lower horizontal portion B to the intermediate inclined portion C. The intermediate inclined portion C is moved toward the upper entrance / exit 14. And if a passenger is a healthy person, when it comes to the upper horizontal part A, it will release a handrail 26, will transfer from the step 11 to the floor board 16 of the upper boarding gate 14, and will walk on the floor board 16 in a desired direction. go.

  However, in the case of passengers who are disabled or elderly passengers, they are transferred to the floor board 16 of the upper entrance 14 while being held by the moving handrail 26. The passenger is guided by the mouth-shaped moving handrail 26 and guided on the floor plate 16 toward the outside of the escalator 1 in the traveling direction of the step 11 while being guided outward in the width direction of the step 11. I will walk slowly. That is, the passenger who has descended on the floor board 16 of the upper entrance / exit 14 walks in a direction deviating outward in the width direction with respect to the moving direction of the subsequent passengers who move on the step 11. As a result, a space for walking on the floor board 16 of the following passenger is expanded, and the subsequent passenger can transfer from the step 11 to the floor board 16 and can walk on the floor board 16 while avoiding the previous passenger. A situation where the mouth 14 is congested is avoided in advance.

Next, a specific example in which the balustrade 20 is formed in a mouth shape will be described with reference to FIGS. 3 and 4.
First, in the region of the intermediate inclined portion C, the balustrade 20 has a substantially horizontal upper side of the guide rail 24 (hereinafter referred to as an upper side of the guide rail 24) on a vertical plane perpendicular to the vertical plane including the traveling direction of the moving handrail 26. And it is extended in parallel with the moving direction of the step 11 so that the height from the step 11 to the upper side of the guide rail 24 may become substantially constant. Further, in the region of the upper horizontal portion A, the balustrade 20 has the step 11 such that the upper side of the guide rail 24 is substantially horizontal and the height from the step 11 to the upper side of the guide rail 24 is substantially constant. It extends parallel to the direction of movement. In the area of the upper entrance 14, as shown in FIG. 3, after the balustrade 20 is bent by the bending portion 30, the upper side of the guide rail 24 becomes substantially horizontal, and the guide rail 24 from the floor plate 16 It extends in a straight line inclined at a predetermined angle with respect to the moving direction of the step 11 so that the height to the upper side is substantially constant. Further, the guide rail 24 is folded at the upper end portion of the balustrade 20 and guided to the inlet.

  In the curved portion 30 of the balustrade 20, as shown in FIG. 4, the angle θ formed between the vertical line and the vertical line on the upper surface of the guide rail frame 22 gradually increases from the curve start point a, and passes through the point b to the curve center point. It is made to gradually decrease after reaching the maximum at c, and to return to zero at the bending end point e after passing through the point d. The height position of the extending end of the flange portion 25 on the inner plate 23 side (outer peripheral side) of the guide rail 24 attached to the upper surface of the guide rail frame 22 is constant from the bending start point a to the bending end point e. It has become. Further, the height position of the extended end of the flange portion 25 on the opposite side (inner peripheral side) of the inner plate 23 of the guide rail 24 attached to the upper surface of the guide rail frame 22 gradually increases from the curve start point a. When the curve center point c is exceeded, the curve gradually decreases and returns to the same height as the curve start point a at the curve end point e.

  At this time, the track length of the extending end of the flange portion 25 on the inner plate 23 side of the guide rail 24 from the bending start point a to the bending end point e in the bending portion 30 is the guide rail 24 extending from the bending start point a to the bending end point e. The angle θ formed by the perpendicular of the upper surface of the guide rail frame 22 in the curved portion 30 and the vertical line is set so as to be equal to the track length of the extended end of the flange portion 25 on the opposite side of the inner plate 23.

  As a result, the traveling distances of the two ear portions 26a of the moving handrail 26 passing through the curved portion 30 of the balustrade 20 become equal, resulting in a difference in curvature radius between the inner peripheral side and the outer peripheral side of the guide rail 24 in the curved portion 30. Thus, the stress generated in the moving handrail 26 is suppressed. Therefore, even if the curving portion 30 is provided in the balustrade 30, the moving handrail 26 can be smoothly traveled and the life of the moving handrail 26 can be extended.

In addition, although the said embodiment demonstrated the escalator, this invention is not limited to an escalator, For example, you may apply to passenger conveyors, such as a moving sidewalk.
Further, in the above-described embodiment, the height position on the outer peripheral side of the guide rail is kept constant at the curved portion of the balustrade, the height position on the inner peripheral side is gradually increased to the maximum height position, and then gradually Although it is supposed to be lower, the height of the outer periphery of the guide rail is kept constant at the curved part of the balustrade, the height of the inner periphery is gradually lowered to the lowest position, and then gradually increased. May be.
Further, in the above embodiment, only the upper horizontal part side of the upper rail entrance of the balustrade is configured as a curved portion, and the entire part corresponding to the upper entrance of the balustrade is configured in an open mouth shape. The entire part corresponding to may be curved in an open mouth shape.

Further, in the above embodiment, the entire part corresponding to the upper entrance of the balustrade is configured as an open mouth, but the distance between the balustrades is widened with the upper horizontal part side of the upper entrance of the balustrade as a curved part. After that, the upper entrance may be configured to maintain a widened distance between the balustrades.
Further, in the above embodiment, the part of the balustrade corresponding to the upper entrance and the lower entrance, the distance between the pair of balustrades of the escalator in the moving direction of the step through the curved portion from the upper horizontal portion and the lower horizontal portion It is assumed that it is configured in a mouth-opening shape that gradually spreads outward, but at least the part of the balustrade corresponding to the exit is an escalator in which the distance between the pair of balustrades passes through the curved part and the step moves What is necessary is just to be comprised by the open mouth shape which spreads gradually toward the outward.
