Description

  The present invention relates to a method for setting a reference for selecting an escalator or an auto slope that assists a pedestrian in a public space.

  In recent years, there have been an increasing number of cases where an auto slope (an inclined moving sidewalk) is introduced for the purpose of assisting the movement of pedestrians in public spaces. Since such an auto slope has no step on the tread surface, there is no need to restrict the walking of the passenger like an escalator, and thus has the advantage that the flow of passengers is not hindered (see Patent Documents 1 to 3 below). ).

On the other hand, however, the above-mentioned auto slope has the slope of the tread surface as it is, so if the slope becomes steep, the burden on the user's body increases or the user falls over in the event of a sudden stop, etc. It can be considered harmful.
In general, escalators are used for places with steep slopes, and auto-slope is used for places with gentle slopes. It is difficult to decide.

  Therefore, in view of the above situation, the present invention, in a gradient range where both an escalator and an auto slope can be installed, is a mathematical formula indicating a preference ratio obtained by comparing the safety of both based on the user's experience evaluation, and An object of the present invention is to provide a method for setting a reference for selecting an escalator or an auto slope using a gradient angle as a reference value.

In order to achieve the above object, the present invention provides
[1] A method for setting an escalator or an auto slope selection criterion, which indicates a ratio of preference for an escalator from the viewpoint of safety in a gradient range where both the escalator and the auto slope can be installed. The gradient angle of the intersection of the value and the value of the following formula (2) indicating the ratio of preference for the auto slope is used as a reference value for selection between the escalator and the auto slope.

y = a + b [(е ^kx −1) / k] (1)
y = 100− {a + b [(е ^kx −1) / k]} (2)
Where a, b, and k are the coefficients shown in the following table, and е is the base of the natural logarithm.

Hereinafter, embodiments of the present invention will be described in detail.
First, in the slope range where both escalators and auto slopes can be installed, the safety of both was compared based on the user's experience evaluation. As a result, the following became clear.
(1) From the standpoint of posture stability, escalators whose treads are horizontal are generally safer than auto slopes, and this is particularly noticeable in descending conditions.

(2) From the viewpoint of the preference rate by the user, auto slope is preferred unless the escalator is significantly lower in the stepping rate. This is considered to be because there are advantages such as no step in the auto slope.
(3) If the deceleration at the time of stopping is suppressed, the safety of both the escalator and the auto slope is improved, but in the preference comparison, the tendency to prefer the escalator becomes stronger.

(4) When an auto slope is installed in a place with a steep slope, the deceleration must be kept lower than 0.6 m / s ² for safety.

Further, when the loose stop method is adopted, if the gradient range is 4 degrees to less than 4.4 degrees, the auto slope ○ is preferred over the escalator □. On the other hand, when the gradient range is 4.4 to 12 degrees, the escalator □ is preferred over the auto slope ◯.

In the present invention, the conventional stop method is a stop method based on the emergency stop deceleration (1.0 m / s ² ) used in many escalators, and the loose stop method considers the influence on passengers. Therefore, this is a stopping method with a slow deceleration (0.6 m / s ² ) that is used by some manufacturers.
Formula (1) which shows the preference characteristic of an above-mentioned escalator can be shown as follows.

y = a + b [(е ^kx −1) / k] (1)
