Description of the Related Art For example, in a man conveyer constructed as an escalator, a large number of steps, which are usually called steps, are connected endlessly, and these steps are provided between one of the entrances and exits and the other entrance and exits of the conveyor. The passengers board from one of the entrances and exits on the stepping body that runs in this way,
When the footstep reaches the other entrance / exit, the person gets off the footstep.

固定されている。The comb 12 is formed in a comb shape having a large number of comb teeth 12a at its tip, and each comb tooth 12a at the tip of the comb 12 is a step.
It engages with the cleat 1a and scoops up foreign matter on the foot 1 and is fixed to the comb mounting beam 11 via screws 13.

れて不測の危険が発生するようなことがある。[0006] By the way, usually, many passengers step up their legs and cross the comb 12 to get off from the top of the step body 1 to the boarding / alighting board 10. However, it is inadvertently or without intentionally raising their feet. There are times when you want to try. In such a case, the foot of the passenger's foot is usually guided by the comb 12 to the side of the boarding / alighting plate 10 to avoid the danger, but sometimes a part of the footwear of the passenger is partially caught by the cleat 1a of the tread 1 and the comb teeth of the comb 12. It may be caught between 12a and 12a, which may cause an unexpected danger.

変形または破断するようになっている。Therefore, in general, the comb 12 is disassembled into a plurality of small pieces 12 'in the left-right longitudinal direction as shown in FIG. 7, and a thin portion 12b is formed in the middle of each small piece 12'. When the passenger's footwear is sandwiched between the cleat 1a and the comb teeth 12a and an external force of a certain amount or more is applied to the comb 12, the pressure causes the small piece 12 'of the comb 12 to be deformed via the thin portion 12b or It is supposed to break.
【０００８】そしてこのようにコム12の小片12′が変形

が発生する。However, even after the comb 12 is deformed or broken, there are cases where the passenger neglects to move the foot from the top of the step body 1 to the side of the boarding / alighting board 10. In such a case,
There is a danger that the footwear may get caught in the gap between the lower surface of the comb attachment beam 11 and the upper surface of the footstep 1 as the footstep 1 progresses, resulting in injury.

である。However, even if the operation of the passenger conveyor is stopped by detecting the intrusion of foreign matter into the inside of the comb by the detection mechanism as described above, the running of the footsteps is detected at the same time. It is difficult to stop, and actually the inertial force causes the running of the tread to proceed to some extent, which may also cause the passenger's footwear to be caught in the gap between the comb mounting beam and the tread. However, there is a lack of certainty in terms of certainty. The points described above are the same in a moving sidewalk or the like that is formed by connecting a large number of footsteps in series.

することが可能な開口部21ｄを設けている。As shown in FIGS. 1 and 2, the comb 21 is fixed to the comb mounting beam 11 with the screw 13 at the edge of the board 10 arranged at the entrance 4. This comb 21 is the conventional comb mentioned above.
Comb teeth 21a whose height difference from the cleat 1a of the treadle 1 is as small as possible with respect to 12, and a thin portion located as low as possible
21b is formed, and a concave 21c with a gentle slope is formed,
An opening 21d through which a guide roller, which will be described later, can be projected is provided substantially in the center of the recess 21c.

向に回転させるものである。The guide roller 22 arranged so that the upper part thereof projects from the above-mentioned opening 21d is made of an elastic material such as rubber and is attached to the lower surface of the comb mounting beam 11 by an arm 23.
Is supported substantially horizontally and rotatably through the, and a plurality of collar rings 22a are provided on the peripheral surface at the same pitch as the comb teeth 21a of the comb 21.
As described above, the upper side of the collar 22a has the recess 21 of the comb 21.
It projects from c, and the lower side meshes with the cleat 1a of the tread 1 to prevent entrapment of foreign matter. A motor 24 is connected to the guide roller 22 via a shaft 22b and is driven to rotate along the running direction of the tread 1. here,
The rotation of the tread 1 in the direction opposite to the traveling direction means the guide roller 22.
The lower side is opposite to the running direction of the tread 1, the upper side is in the same direction, and the comb teeth 21a side of the comb 21 of the guide roller 22 is rotated upward.

際の衝撃も緩和される。Next, the operation of the embodiment configured as described above will be described with reference to FIG. When the step body 1 travels, the guide roller 22 is rotated at a constant speed via the motor 24. Since the comb teeth 21a of the comb 21 have a height difference with the cleat 1a of the foot 1 as small as possible, the footwear 25 of the passenger is sandwiched between the cleat 1a of the foot 1 and the comb teeth 21a of the comb 21a. It becomes difficult to get it. Further, even when the passenger neglects to move his / her foot from the top of the footstep 1 toward the boarding / alighting board 10, the footwear 25 of the passenger hits the guide roller 22, and the lower surface of the comb mounting beam 11 and the upper surface of the footstep 1 are contacted. Since the guide roller 22 is driven by the motor 25 to rotate upward on the comb teeth 21a side, the footwear 25 is scooped up, The danger that the passenger's footwear 25 is caught in the gap between the comb mounting beam 11 and the step body 1 is reliably prevented. Further, since the guide roller 22 is formed of an elastic material, the impact when the footwear 25 of the passenger hits the guide roller 22 is also mitigated.

確実にすくい上げられて除去される。On the other hand, when foreign matter such as pebbles intervenes on the foot 1 at normal times, the comb teeth 21a of the comb 21 and the collar ring 22a of the guide roller 22 are doubled on the cleat 1a of the foot 1. Since it is meshed with, the foreign matter is reliably picked up and removed by the comb teeth 21a and the collar 22a.

したマンコンベアの乗降口安全装置を提供できる。As described above, according to the present invention, the comb attached to the edge of the boarding / alighting board at the entrance / exit is formed in a concave shape with a gentle slope, and the direction of travel of the footsteps is changed by the motor. Since a guide roller that is driven to rotate in the opposite direction is provided, and the upper side of this guide roller is made to project to approximately the center of the concave shape of the comb, the footwear of the passengers who ride on the foot will be the cleat of the foot. It becomes difficult to pinch it between the comb teeth of the comb and the passenger's footwear is blocked by the guide rollers even if the passenger neglects to move the foot from the top of the tread to the boarding side. Intrusion into the gap between the lower surface of the comb mounting beam and the upper surface of the footstep is prevented, and the footwear of the passenger is scooped up by the rotation of the guide roller, so that the footwear of the passenger is separated from the comb mounting beam and the footstep. There is a danger of getting caught in the gap Is indeed avoided, it can provide a doorway safety device passenger conveyor that further improve safety.
