Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor for guiding and transporting passengers from an upper floor to a lower floor, from a lower floor to an upper floor, or in a horizontal direction, and in particular, a passenger installed near an entrance / exit of the passenger. The present invention relates to a conveyor entrance / exit device.

[0002]

2. Description of the Related Art Conventionally known passenger conveyors, so-called escalators, are provided with measures to prevent passengers from pulling in their legs (for example, Japanese Utility Model Laid-Open No. 52-1252).
See Microfilm Publication No. 94. ).

FIG. 3 is a schematic view of the above-mentioned Japanese Utility Model Laid-Open No. 52-12529.
1 shows a passenger conveyor 1 provided with measures for preventing passengers from pulling in their feet as disclosed in No. 4 microfilm publication.

This passenger conveyor 1 is arranged in an endless manner and is rotated in a predetermined direction by a plurality of steps 2 (only one is shown in the figure), and a rotation movement is performed in synchronization with the rotation movement of step 2. A handrail 3 as a moving handrail, a balustrade 4 arranged below the handrail 3 in the vicinity of the passenger transport area used as a moving handrail, and step 2
The skirt guard 5 is disposed on both outer sides of the rail with a slight gap, and the safety valve 6 fixed to the balustrade 4 and wrapped in the air above the outer side of the step 2.

Between both outer sides of the step 2 and the skirt guard 5 are prevented from interfering with each other during the rotational movement of the step 2 to cause a squeaking noise or abrasion.
A gap of about mm is set.

The safety valve 6 is arranged continuously along the entire length of the passenger carrying area set in accordance with the rotational movement in step 2, and is made of a material having a low friction resistance. This prevents the foot from being caught in the gap between the step 2 and the skirt guard 5 described above.

[0007]

By the way, in the passenger conveyor entrance / exit device configured as described above, since the safety valve 6 is fixed to the balustrade 4, the P between the step 2 and the safety valve 6 is fixed. Since the shoes S are widely open, the shoes S are likely to approach the skirt guard 5, and there is a problem that the measures are not a reliable measure for preventing entanglement.

Further, since the safety valve 6 is a mere "protrusion", when a passenger gets on and off, he / she must step up to step 2 while confirming the position of the safety valve 6, and when using it for passengers. It imposes a burden on the safety of.

Further, when the passenger conveyor 1 is of a boarding / alighting type,
Due to the vertical displacement in step 2, the interval P between the entrance / exit area and the vicinity of the center of the passenger transportation area is different. In particular, when the toe of the shoe S is in the downward direction, which is located on the open end side of the step 2, the interval P is widest on the upstream side in the moving direction of the step 2 near the doorway where the step 2 is moving horizontally. In the downstream side of the moving direction of the step 2 in the vicinity of the doorway where the step 2 is moving in the horizontal direction, the space P becomes the narrowest in combination with the balustrade 4 moving obliquely downward.

On the other hand, since the shoe S generally protrudes outward from the ankle toward the toe, if P changes during the above-mentioned period, the toe area is forcibly narrowed regardless of the passenger's intention. There is a problem that the shoe S is sandwiched between the step 2 and the safety valve 6 because of being guided toward P, and in particular with the recent increase in the thickness of women's shoes.

In order to solve the above problems, the present invention can realize a more reliable measure for preventing shoes from being caught.
Moreover, it is an object of the present invention to provide an entrance / exit device for a passenger conveyor that can reduce the burden on the safety of passengers.
