Description

  The present invention relates to a passenger conveyor device in which a plurality of passenger conveyors that are operated in the same direction are installed in a building, and more particularly to a passenger conveyor device that efficiently and smoothly transports a user and ensures safety.

When installing multiple passenger conveyors in a building, as a passenger conveyor device that transports passenger conveyor users efficiently and smoothly and prevents stagnation on the user's flow line, ensuring safety Combines a normal speed passenger conveyor that can be operated only at normal speed and a speed-switchable passenger conveyor that can switch operation speed in multiple stages, and installs multiple passenger conveyors at appropriate locations in the building. There is a type of passenger conveyor that is operated while switching the operation speed according to the time zone and the congestion situation (see, for example, Patent Document 1).
JP-A-2005-29323 (paragraph numbers 0016 to 0024, FIG. 1)

  However, the above-described conventional passenger conveyor device requires a speed-switching passenger conveyor equipped with power conversion means such as an inverter that changes the speed, resulting in an increase in the cost of the device. Further, the variable control of the operation speed requires an operator or is effective only for a fixed time, and as a result, there is a problem that it is difficult to accurately cope with the use state of the passenger conveyor.

  The present invention was made from the actual situation in the above-described prior art, and its purpose is to provide a passenger conveyor device that can prevent the user from staying on the flow line without requiring the installation of a speed switching type passenger conveyor. It is to provide.

In order to achieve the above object, the invention according to claim 1 of the present invention is to install a plurality of passenger conveyors, one entrance and one exit , operated in the same direction in a building, In a passenger conveyor device in which a user draws a single flow line toward a predetermined position, the step width of at least one passenger conveyor before the traveling direction is set smaller than the step width of a subsequent passenger conveyor It is said.

  In the invention according to claim 1 of the present invention configured as described above, the step width of at least one passenger conveyor positioned in front of the moving direction, that is, in front of the user's flow line, is set as the subsequent passenger conveyor in the flow line. By setting it to be smaller than the step width, the carry amount of the succeeding passenger conveyor is made larger than that of the front passenger conveyor. This makes it possible to prevent the user from staying on the flow line without requiring the installation of a speed-switching passenger conveyor.

  Further, the invention according to claim 2 of the present invention is characterized in that the step width is set to be increased stepwise from the passenger conveyor before the traveling direction toward the subsequent passenger conveyor.

  In the invention according to claim 2 of the present invention configured as described above, the step width is set to be gradually increased from the passenger conveyor positioned in front of the user's flow line toward the subsequent passenger conveyor in the flow line. Thus, in a plurality of passenger conveyors, the transport amount of the succeeding passenger conveyor gradually becomes larger than that of the front passenger conveyor. This can more reliably prevent the user from staying on the flow line.

  ADVANTAGE OF THE INVENTION According to this invention, without requiring installation of a speed-switching type passenger conveyor, ie, without causing cost improvement, a stay on a user's flow line can be prevented and safety can be improved.

  Embodiments of a passenger conveyor device according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a passenger conveyor, and FIG. 2 is an explanatory diagram showing an embodiment of a passenger conveyor device according to the present invention.

  As shown in FIG. 1, the passenger conveyor, for example, the escalator 1, is installed across the upper and lower floors, and is composed of an upper horizontal frame 2a, an intermediate inclined frame 2b, and a lower horizontal frame 2c, and an upper horizontal frame. A driving sprocket 3 pivotally supported in 2a, a driven sprocket 4 pivotally supported in the lower horizontal frame 2c, and a step chain 5 wound endlessly across the driving sprocket 3 and the driven sprocket 4; The balustrade panel 6 erected along positions corresponding to both sides of the frame 2 in the width direction, the moving handrail 7 guided and moved by the periphery of the balustrade panel 6, and the step chain 5 and the moving handrail 7 are driven. And a plurality of steps 9 having step plates that are connected to the step chain 5 and are always held horizontally on the forward path side.

  FIG. 2 shows that a plurality of, for example, three escalators are installed in a building such as a department store or a shopping center, and a user moves from the first floor A to the second floor B and the third floor C toward the fourth floor D. In this example, it is assumed that one flow line is drawn, and the escalator 1A, escalator 1B, and escalator 1C are arranged from the lower floor side, and these three units are in the same driving direction of the ascending operation. The escalator 1A is set to the step width Wa, the escalator 1B is set to the step width Wb, the escalator 1C is set to the step width Wc, and the step widths Wa, Wb, and Wc have a relationship of Wa <Wb <Wc. That is, as the escalators 1A to 1C are used to proceed to the upper floor, the step width increases and the conveyance amount increases.

  According to the present embodiment, a plurality of passengers are set by gradually increasing the step width from the passenger conveyor 1A located in front of the user's flow line toward the subsequent passenger conveyor 1C in the flow line. In the conveyor, the transport amount of the succeeding passenger conveyor gradually increases from the passenger conveyor in front. As a result, the user can be prevented from staying on the flow line, and the safety can be improved. In addition, since it is not necessary to install a special escalator, that is, a speed switching type passenger conveyor, the user can be efficiently and smoothly transported without causing an increase in cost.

  FIG. 3 is an explanatory view showing another embodiment of the passenger conveyor device according to the present invention.

  The passenger conveyor apparatus shown in FIG. 3 shows an example in which three escalators 1A to 1C are installed as shown in FIG. 2 described above, but the setting of the step width is different. That is, in this embodiment, the relationship between the step width Wa of the escalator 1A and the step width Wb of the escalator 1B is Wa <Wb as in FIG. 2, but the relationship between the step width Wb of the escalator 1B and the step width Wc of the escalator 1C is Wb. = Wc. That is, Wa <Wb = Wc holds for the relationship between the step widths.

  According to another embodiment, depending on the use situation of the building, the step width is varied between the required floors, and the passenger conveyor located in front of the user's flow line is followed by the subsequent line in the flow line. The carrying amount of the passenger conveyor is increased, thereby preventing the user from staying on the flow line without requiring the installation of a speed switching type passenger conveyor.

  In addition, although embodiment mentioned above demonstrated taking the escalator as an example as a passenger conveyor apparatus, it cannot be overemphasized that this invention is applicable not only to this but an electric road.

It is a schematic block diagram of a passenger conveyor. It is explanatory drawing which shows one Embodiment of the passenger conveyor apparatus which concerns on this invention. It is explanatory drawing which shows other embodiment of the passenger conveyor apparatus which concerns on this invention.
