As described above, in the safety device 20 and the passenger conveyor 1 of the present embodiment, the step 2 at the end (first end) of the safety device 20 on the opposite side of the entrance/exit 8 changes from upward movement to substantially parallel movement. It is positioned on the entrance/exit 8 side of the position A and on the entrance/exit 8 side from the substantially central position of the tread surface 2a1 of the step 2 that moves substantially in parallel. Therefore, according to the present embodiment, even if luggage such as a suitcase comes into contact with the deflector 24 or the cap 32 at the tip and topples over during the ascending operation, it is possible to prevent the luggage from falling toward the lower floor. can.

That is, in the passenger conveyor of the comparative example, the ends of the safety device 20 and the deflector on the side opposite to the entrance/exit 8 are located on the opposite side of the entrance/exit 8 from the substantially central position of the tread surface of the step that moves substantially in parallel. . FIG. 13 is an explanatory diagram showing a state when the passenger conveyor of the comparative example comes into contact with the deflector.

As shown in FIG. 13( a ), in the passenger conveyor of the comparative example, the deflector is located on the opposite side of the doorway 8 from the substantially central position X of the tread surface of the step that moves substantially in parallel. It is assumed that the user moves up with a load 50 placed on the step 2 and comes into contact with the deflector (FIG. 13(b)). In this case, the baggage 50 is pulled toward the lower floor by contact with the deflector (FIG. 13(c)). Then, the cargo 50 moves to the rear step, and the cargo 50 inclines (Fig. 13(d)) and overturns (Fig. 13(e)). It rolls on a sloping part formed by a plurality of steps and falls toward the lower floor.

On the other hand, in this embodiment, as shown in FIG. 6(a), the end (first end) of the deflector 24 on the side opposite to the entrance/exit 8 causes the step 2 to move substantially parallel from the upward movement. It is positioned on the entrance/exit 8 side from the position A where the position A changes and on the entrance/exit 8 side from the substantially central position X of the tread surface 2a1 of the step 2 that moves substantially in parallel.

It is assumed that the user puts the baggage 50 on the step 2, moves upward, and comes into contact with the deflector 24 (FIG. 6(b)). In this case, the baggage 50 is pulled toward the lower floor by contact with the deflector (FIG. 6(c)). Then, the load 50 moves to the rear step, and the load 50 inclines (FIG. 6(d)) due to the difference in level with the rear step and falls (FIG. 6(e). However, in this embodiment, the load 50 is , not on the slope formed by the rising steps, but on the treads 2a1 of the steps that are moving substantially in parallel, that is, the treads 2a1 of the two steps 2 are horizontal. You will not fall.

Therefore, according to the present embodiment, even if luggage such as a suitcase comes into contact with the deflector 24 or the cap 32 at the tip and topples over during the ascending operation, it is possible to prevent the luggage from falling toward the lower floor. can.

(Second embodiment)
In the safety device 20 and the passenger conveyor 1 of the first embodiment, the end (first end) of the safety device 20 on the side opposite to the entrance 8 is positioned at the position where the step 2 changes from upward movement to substantially parallel movement. It is located on the side of the entrance/exit 8 from A and is located on the entrance/exit 8 side from the substantially central position of the tread surface 2a1 of the step 2 that moves substantially in parallel, thereby preventing the luggage from falling even if it falls over. In this second embodiment, the end (first end) of the safety device 20 on the side opposite to the doorway 8 is the doorway of the step 2 that moves substantially parallel to the doorway 8 side of the changed position. It is located on the doorway 8 side from the edge on the 8 side.

The configurations of the passenger conveyor 1 and the safety device 20 of this embodiment are the same as those of the first embodiment described with reference to FIGS.

FIG. 7 is a perspective view showing a state in which the safety device 20 of the second embodiment is attached to the skirt guard panel 14. FIG. FIG. 8 is a schematic diagram showing the positional relationship between the tread surface 2a of the step 2 on the upper floor side and the safety device 20 of the second embodiment. The shapes of the base 122, the two caps 32, and the deflector 124 of this embodiment are the same as those of the first embodiment.

In this embodiment, the base 122 and the deflector 124 are shorter in length than the base 22 and the deflector 24 of the first embodiment. Specifically, as shown in FIGS. 7 and 8, in the safety device 20 of the present embodiment, the end (first end) of the safety device 20 opposite to the entrance 8, that is, the entrance 8 The end of the cap 32 and the deflector 124 on the opposite side is located on the doorway 8 side from the position A where the step 2 changes from upward movement to approximately parallel movement, and the doorway 8 of the tread surface 2a1 of the step 2 moves approximately parallel. It is located on the boarding/alighting opening 8 side from the side edge Y.

On the other hand, as shown in FIGS. 7 and 8, the second end of the safety device 20 opposite to the first end, that is, the tip of the cap 32 and the deflector 124 on the side of the entrance/exit 8 is the first end. As in the embodiment, it is located at a predetermined distance from the end 33 of the boarding plate 53 of the passenger conveyor 1 .

Therefore, in this embodiment, the base 122 and deflector 124 are shorter in length than the base 22 and deflector 24 of the first embodiment.

In the case of the safety device 20 in which the cap 32 is not provided, the deflector 124 or the end of the base 22 on the side opposite to the entrance/exit 8 will move substantially parallel to the entrance/exit 8 side of the change position A. The safety device 20 may be configured so as to be positioned at the edge Y of the tread surface 2a1 of the step 2 on the entrance/exit 8 side.

Also, in the case of the safety device 20 without the cap 32, the deflector 124 or the end of the base 122 opposite to the entrance 8 is positioned at a predetermined distance from the end 33 of the boarding plate 53 of the passenger conveyor. The safety device 20 may be configured to be spaced apart.

When attaching the safety device 20 of this embodiment configured in this manner to the skirt guard panel 14, first, the operator positions the attachment position of the safety device 20 to the skirt guard panel 14. As shown in FIG. Specifically, the operator places the tip of the cap 32 as the first end on the skirt guard panel 14 on the upper story side, and moves the step 2 from the transition position A from the upward movement to the substantially parallel movement to the boarding/alighting opening 8 . A pop nut is attached to the skirt guard panel 14 so that it is positioned at the edge Y on the entrance/exit 8 side of the tread surface 2a1 of the step 2 that moves substantially parallel. The mounting procedure beyond this is the same as in the first embodiment.

As described above, in the safety device 20 and the passenger conveyor 1 of the present embodiment, the end of the cap 32 and the deflector 124 on the side opposite to the entrance 8 is positioned at the entrance from the position A where the step 2 changes from upward movement to approximately parallel movement. It is positioned on the doorway 8 side from the edge Y on the doorway 8 side of the tread surface 2a1 of the step 2 that is on the 8 side and moves substantially in parallel. Therefore, according to the present embodiment, it is possible to prevent luggage such as a suitcase from coming into contact with the deflector 24 and the tip cap 32 and falling over during the ascending operation.

FIG. 9 is an explanatory view showing a state when contacting the deflector 124 (or the cap 32) in the passenger conveyor 1 of the second embodiment. In this embodiment, as shown in FIG. 9(a), the end (first end) of the deflector 124 on the opposite side of the entrance/exit 8 is positioned at a position A where the step 2 changes from upward movement to substantially parallel movement. It is located at the edge Y of the tread surface 2a1 of the step 2 which is closer to the entrance 8 and moves substantially in parallel.

It is assumed that the user moves up with the load 50 placed on the step 2 and comes into contact with the deflector 124 (FIG. 9(b)). In this case, the load 50 is pulled toward the lower floor by contact with the deflector 124 (FIG. 9(c)). However, in the present embodiment, the tread surface 2a1 of the step 2 that is moving substantially parallel, that is, the tread surface 2a1 of the two steps 2 on which the load 50 is placed is horizontal. can avoid overturning (Fig. 9(d)).

Therefore, according to the present embodiment, it is possible to prevent luggage such as a suitcase from coming into contact with the deflector 24 and the tip cap 32 and falling over during the ascending operation.

(Modification)
Modifications of the above embodiment will be described below.
In the above embodiment, the position of the deflector has been described by taking as an example a case in which two steps 2 move substantially parallel from the upward movement past the change position A, but the number of steps 2 that move substantially parallel is limited to two. not a thing For example, it is possible to apply the safety device 20 of the above-described embodiment when the number of steps 2 that move substantially parallel is three or more but less than two.

That is, in the first embodiment, the end (first end) of the safety device 20 on the side opposite to the entrance 8 is closer to the entrance 8 than the position A where the step 2 changes from upward movement to approximately parallel movement. , and should be located on the entrance/exit 8 side from the substantially central position of the tread surface 2a1 of the step 2 that moves substantially in parallel. In the second embodiment, the end of the cap 32 and the deflector 124 on the side opposite to the entrance 8 is substantially parallel to the entrance 8 side from the position A where the step 2 changes from upward movement to approximately parallel movement. It is sufficient that the tread surface 2a1 of the moving step 2 is located on the doorway 8 side from the edge Y on the doorway 8 side. On the other hand, the tip of the cap 32 and the deflector 124 on the entrance/exit 8 side may be located at a predetermined distance from the end 33 of the boarding/alighting plate 53 of the passenger conveyor 1, as in the first embodiment. Therefore, the length of the deflectors 24, 124 and the base 22 varies depending on the number of the steps 2 that move substantially parallel. That is, the length of the deflector 24 increases as the number of the steps 2 that move substantially in parallel increases.

FIG. 10 is a schematic diagram showing the positional relationship between the tread surface 2a of the step 2 on the upper floor side and the safety device 20 in the passenger conveyor of the modified example. indicates the case. FIG. 11 is a schematic diagram showing the positional relationship between the tread surface 2a of the step 2 on the upper floor side and the safety device 20 in the passenger conveyor of the modified example. A single case is shown. As shown in FIGS. 10 and 11, it can be seen that the length of the deflector 24 increases as the number of steps 2 that move substantially parallel increases.

The shape of the deflectors 24, 124 as viewed from above is not limited to those of the first and second embodiments. FIG. 12 is a schematic diagram showing the shape of the deflector of the modification as viewed from above.

As shown in FIG. 12, the deflector 224 of the safety device 120 of the modified example is formed in a substantially flat plate shape, similar to the first and second embodiments. It has a long strip shape. Also, as shown in FIG. 12, the deflector 224 of the modified example has an edge portion on the side of the base 22 and an edge portion on the side of the base 22 from the center portion to the front of both ends when viewed from above, as in the first and second embodiments. The edge of the step 2 on the side of the central portion extends the same distance (that is, the same width). Then, the deflector 224 of the modified example is curved in a gently rounded shape so as to gradually become concave inward (toward the skirt guard panel 14) as it approaches each of the ends. The edge portion and the edge portion of the step 2 on the central portion side are connected to each other.

As described above, the deflector 224 of the modified example is curved in a gently rounded shape so that it gradually becomes concave toward the inner side (toward the skirt guard panel 14) as it approaches each of the ends, so that it is possible to prevent the step from rising. 2 is less likely to come into contact with the end of the deflector 224, and the possibility of overturning of the load can be reduced.
