The gap, the gap between the lower portion of the handrail 5 and the upper floor 2, is small, and a part of a person's body or an object is easily caught.

The present invention has been made in view of the above-mentioned circumstances in the prior art, and an object thereof is to provide a passenger conveyor capable of increasing the gap between the lower portion of the handrail and the floor. .

[0009]

In order to achieve this object, the present invention provides a hand rail that is driven in synchronization with a step, and a hand rail which is provided at an inlet of the hand rail and is operated in accordance with an ON operation. In a passenger conveyor equipped with a rail and a safety switch for stopping the driving of the step, the handrail is a handrail that moves in only one direction, and the folding part on one end side of the upper handrail and the entry The dimension between the inlet and the other end of the handrail is set to be larger than the dimension between the folded portion on the other end side and the inlet on the other end side, and the one end side The safety switch is provided at the entrance.

According to the present invention constructed as described above, since the dimension between the turn-back portion on one end side located in the traveling direction of the handrail and the inlet is set large, this The curve of the folded portion of the handrail on the one end side can be increased.

As a result, the gap between the lower portion of the handrail on the one end side and the floor can be made relatively large, and it is possible to make it difficult for a person's body or part to be caught.

Further, since the dimension between the folded-back portion on the other end located on the side opposite to the direction of travel of the handrail and the inlet is set small, the total length of the handrail is made equal to the conventional one. Therefore, the total length of the passenger conveyor can be kept the same as before.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a passenger conveyor according to the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing a first embodiment of the present invention, and FIG. 2 is a side view showing a second embodiment of the present invention.

FIGS. 1 and 2 are drawn corresponding to FIG. 3 described above. Of the reference numerals shown in FIGS. 1 and 2, the same reference numerals as those shown in FIG. 3 indicate the equivalents.

For example, in the first embodiment shown in FIG.
Between the lower floor 1 and the upper floor 2, a frame 3 forming a base frame of a passenger conveyor, that is, an escalator is arranged, a balustrade 4 is provided on the frame 3, and a handrail 5 can be moved to the balustrade 4. Is attached to.

In particular, in the first embodiment, the handrail 5 is set so as to be movable only in one direction, that is, in the ascending direction, as shown by an arrow 15, and one end of the handrail 5 is set. The dimension T ₁ between the side folded-back portion 9a and the inlet 7 of the handrail 5 is larger than the dimension T ₂ between the other folded-back portion 8 and the inlet 6 of the handrail 5. Is also set large. The relationship between these dimensions T ₁ and T ₂ and the dimension t shown in FIG.
_1> t, and has a T ₂ <t. The curve of the folded portion 9a along with the fact that larger dimensions T _1, is set larger than the curve of the folded portion 9 shown in FIG.
Further, since the handrail 5 is a handrail that moves in only one direction, the safety switch 11 is provided at the inlet 7 and the safety switch is not provided at the inlet 6 side. Further, by increasing the size T ₁ and decreasing the size T ₂ , the total length of the handrail 5 is set to be equal to the length of the handrail 5 shown in FIG. 3 described above. Along with this, the entire length of the frame 3 and the balustrade 4, that is, the total length of the escalator is made equal to the total length of the escalator shown in FIG.

At the front position of the safety switch 11,
Safety fence 13 to prevent parts of the body and things from being caught
Is arranged.

In the first embodiment constructed as described above,
As the dimension T ₁ is set large as described above, the curve of the folded portion 9a can be increased.
A gap between the lower part of the folded-back portion 9a and the upper floor 2 can be increased, and therefore a part of a person's body or an object is less likely to be caught in this gap, and safety is improved. Further, since the total length of the passenger conveyor can be set to be equal to the conventional one, the production cost will not be increased.

In the second embodiment shown in FIG. 2, contrary to the above-described first embodiment, the handrail 5 is set to be movable only in one direction indicated by an arrow 14, that is, in the descending direction. , The dimension T ₁ between the folded-back portion 8a on one end side of the handrail 5 and the entry port 6 of the handrail 5 is set to be equal to the dimension of the folded-back portion 9 on the other end side and the entry of the handrail 5. It is set to be larger than the dimension T ₂ between the mouth 7.

Even in the second embodiment constructed as described above, the gap between the lower portion of the folded-back portion 8a and the lower floor 1 can be increased, and therefore, a part of the human body can be placed in this gap. Hard to be caught and the safety is improved. Further, as in the first embodiment, the total length of the passenger conveyor can be set to be equal to the conventional one.

[0022]

EFFECTS OF THE INVENTION Since the present invention has the above-described structure, the gap between the lower portion of the handrail and the floor can be increased, and a part of a person's body or an object can be caught in this gap. It becomes difficult and the safety is improved compared to the conventional one.
