detailed description

Hereinafter, embodiment of the passenger conveying facility of this invention is demonstrated based on drawing.

(Embodiment 1)

As shown in Fig. 6, the passenger conveying equipment of Embodiment 1 includes: a lifting floor 1 arranged on the floor surface of a building structure; Railings 3 installed on the unshown frame and arranged on both sides along the moving direction of the steps 2; cover plates 4 provided at the bottom of the railings 3; moving handrails that move in a ring along the outer circumference of the railings 3 5; an entrance portion 6 opening at the end of the cover plate 4 as an entry portion of the moving handrail 5 ; and a safety device 7 provided in the entrance portion 6 . The steps 2 and the moving handrail 5 are driven in the same direction by a driving device described later.

As shown in Figure 1, the safety device 7 has an elastic structure 8 arranged at the entrance 6, an entrance switch 9 that detects the movement of the elastic structure 8, and controls the alarm device 10 and the drive according to the output signal from the entrance switch 9. Control device 12 of device 11 .

In the passenger conveying facility of Embodiment 1, in order to reduce the unnecessary operation of the entrance switch 9, studies have been made. Specifically, as shown in FIGS. The main body 8a and the protruding part 8b extending from the main body 8a along the moving handrail 5 are configured. The protruding part 8b is configured not to cover at least a part of the side part 5b of the moving handrail 5. protrude. In addition, in the present application, the side portion 5b of the moving handrail 5 refers to a curved portion provided at the widthwise end of the moving handrail 5 when the moving handrail 5 is viewed in a cross section perpendicular to the advancing direction of the moving handrail 5 . In addition, let the center part sandwiched between both side parts 5b of the moving handrail 5 be the center part 5a.

The elastic structure 8 comes into contact with the foreign matter that enters the entrance 6, and functions as an operating member of the entrance switch 9, has elasticity to the extent that the foreign matter caught in the entrance 6 is not damaged, and reliably transmits external force. Appropriate rigidity for the inlet switch 9 is molded from rubber, for example.

The entrance switch 9 is, for example, a push switch, and is attached to a bracket 13 fixed to the inner surface of the cover plate 4 or to a frame of a passenger conveying device not shown.

The alarm device 10 can be a device that emits an alarm sound such as a buzzer or a bell, a device that uses sound to issue an alarm, a device that uses light to display a warning, or a combination of them, etc., which belong to any known alarm device. .

In Embodiment 1, the protruding portion 8b of the elastic structure 8 does not have a substantially C-shaped cross-sectional shape to cover the periphery of the moving handrail 5 as in the conventional art, but has a rectangular cross-sectional shape along the horizontal portion 5a of the moving handrail 5 . Passengers' luggage often collides with the entrance portion 6 from an oblique direction. Therefore, by omitting the portion opposite to the side portion 5a of the moving armrest 5, the portion along the central portion 5a of the moving armrest 5 is used as the protrusion 8b, thereby reducing the burden on the passenger. When luggage collides with the protruding portion 8b, unnecessary operations of the entrance switch 9 are further reduced. On the other hand, when a foreign object is caught between the moving handrail 5 and the elastic structure 8 in practice, the protruding portion 8 b is reliably displaced to operate the entrance switch 9 .

The protruding portion 8b of the elastic structure 8 provided at the entrance 6 accidentally collides with the passenger's luggage or the like in many cases instantaneously, and the entrance switch 9 outputs a pulse-like output signal with a short signal length. On the other hand, when a foreign object is caught between the moving handrail 5 and the elastic structure 8 actually, the output signal is continuously output from the entrance switch 9 .

When the control device 11 determines that the signal length of the output signal of the entrance switch 9 does not reach the preset threshold, it keeps driving the steps 2 and the moving handrail 5, and activates the alarm device 14 to issue an alarm to passengers. Thereby, it is possible to attract the attention of passengers, prevent foreign matter from being caught in the entrance portion 6, and not stop driving the steps 2 and the moving handrail 5, so that the proper use of the passenger conveying facility can be ensured.

On the other hand, when the control device 11 determines that the signal length of the output signal of the entrance switch 9 has reached a preset threshold value, it immediately stops driving the steps 2 and the moving handrail 5 . Thereby, even if a foreign object is caught, the foreign object removal process etc. can be performed rapidly, Therefore The damage of a foreign object and a passenger conveying facility can be suppressed to the minimum.

Preferably, when the driving of the step 2 and the moving handrail 5 are stopped, the alarm device 14 is activated in conjunction with this to issue an alarm to passengers and attendants. According to the above structure, it is possible to notify the attendant and passengers that the steps 2 and the moving handrail 5 have stopped, or that the entrapment has occurred, so that appropriate handling can be promptly performed.

According to Embodiment 1, the portion of the elastic structure 8 along the central portion 5a of the moving armrest 5 is provided as the protruding portion 8b extending from the main body portion 8a, thereby reducing the contact surface against which the passenger's luggage etc. collides. Reducing unnecessary actuation of the entrance switch 9 prevents unnecessarily issuing an alarm or stopping the driving of the passenger conveyor. On the other hand, in practice, when a foreign object is caught between the moving handrail 5 and the elastic structure 8, the protruding portion 8b is reliably displaced, the entrance switch 9 is activated, and the drive of the steps 2 and the moving handrail 5 can be stopped. Be safe.

(Embodiment 2)

Here, Embodiment 2 of the passenger conveying facility of this invention is demonstrated based on drawing.

As shown in FIG. 5 , in the passenger conveying facility according to Embodiment 2, a notch 19 is formed in a handrail-side joining portion between the main body portion 18 a and the protrusion portion 18 b of the elastic structure 18 .

In Embodiment 2, when a foreign object is caught between the moving handrail 5 and the elastic structure 18, since the notch 19 is formed at the handrail-side junction between the main body portion 18a and the projecting portion 18b, the projecting portion 18b is caught by the foreign object. Pressing makes it easier to displace toward the moving handrail 5 , and slides in contact with the moving moving handrail 5 in a state of entering the entrance portion 6 . In this way, the protruding portion 18b is in sliding contact with the moving handrail 5, further receiving an external force, the main body portion 18a is also largely displaced, and the entrance switch 9 is reliably operated.

According to Embodiment 2, the flexibility of the main body 18a is improved by forming the notch 19 at the armrest-side junction between the main body 18a and the protruding portion 18b. , can reliably make the entrance switch 9 action.

In addition, the present embodiment described above is an embodiment described in detail to describe the present invention in an easy-to-understand manner, and is not necessarily limited to having all the configurations described. In addition, addition, deletion, and replacement of other configurations can be performed on part of the configurations of the above-described embodiments.
