As a result, the lower floor side of the passenger conveyor 1 becomes the fixed end, and the upper floor side becomes the free end. The lower floor side of the passenger conveyor 1 may be a free end and the upper floor side may be a fixed end, or the lower floor side and the upper floor side of the passenger conveyor 1 may be free ends, respectively. Then, the slide floor is arranged on the free end side of the passenger conveyor 1.

1-2. Configuration of Upper Floor (Slide Floor) Next, the configuration of the upper floor 4B showing the slide floor will be described with reference to FIGS. 2 to 4.
FIG. 4 is an enlarged cross-sectional view showing the tip of the upper floor 4B.

As shown in FIGS. 2 and 3, the upper boarding / alighting floor 4B is arranged above the support angle 9 and extends from the frame 2 toward the upper cradle 201B. The upper floor 4B is arranged in the upper cradle 201B so that the upper surface thereof is at the same height as the finished floor 203 of the building structure 200.

The upper floor 4B has a pair of joint members 21 and 21, a floor main body 25, and a support member 26. The tip of the floor body 25 on the side opposite to the frame 2 faces the wall surface 201a formed in the direction orthogonal to the width direction of the upper cradle 201B.

The floor body portion 25 has a tread plate member 22, a reinforcing member 23, and a bracket member 24. Then, the bracket member 24, the reinforcing member 23, and the tread plate member 22 are laminated in this order from the lower side in the vertical direction.

The tread plate member 22 is formed of a substantially flat plate-shaped member. The tread plate member 22 serves as a decorative surface for the upper floor 4B. A reinforcing member 23 is fixed to the lower surface portion of the tread plate member 22 on the lower side in the vertical direction. The reinforcing member 23 is formed thicker than the tread plate member 22, and reinforces the tread plate member 22.

The bracket member 24 is fixed to the side of the reinforcing member 23 opposite to the tread plate member 22, that is, to the lower surface portion. The bracket member 24 supports the tread plate member 22 and the reinforcing member 23. The bracket member 24 is attached to a support member 26 provided above the support angle 9. As a result, the floor body 25 is supported by the support member 26. The floor body 25 projects substantially horizontally from the frame 2 and the support angle 9 toward the building structure 200.

As shown in FIG. 4, the tip portion 22a of the tread plate member 22 protrudes toward the wall surface portion 201a from the tip portions 23a and 24a of the reinforcing member 23 and the bracket member 24. Further, the tip portion 23a of the reinforcing member 23 projects toward the wall surface portion 201a from the tip portion 24a of the bracket member 24. Further, the tread plate member 22, the reinforcing member 23, and the tip portions 22a, 23a, 24a of the bracket member 24 are not tapered.

The configuration of the floor body portion 25 is not limited to the above-mentioned example, and the tread plate member 22 and the reinforcing member 23 may be integrally formed, or the reinforcing member 23 and the bracket member 24 may be integrally formed. You may. Alternatively, the tread plate member 22, the reinforcing member 23, and the bracket member 24 may all be integrally formed.

As shown in FIG. 2, joint members 21 are fixed to both ends of the floor body 25 in the width direction. The joint member 21 is arranged in a gap formed on both sides of the floor main body 25 and the upper cradle 201B in the width direction.

As shown in FIGS. 3 and 4, the tip portion of the joint member 21 on the side opposite to the frame 2 on the entrance / exit side faces the wall surface portion 201a of the upper cradle 201B. Further, a tapered portion 21a inclined in the vertical direction is formed at the tip portion of the joint member 21. The tapered portion 21a is inclined so that the lower surface of the joint member 21 continuously approaches the upper surface as the distance from the frame 2 increases. The tapered portion 21a of the joint member 21 faces the wall surface portion 201a of the upper pedestal 201B and the mounting surface of the upper pedestal 201B. Further, the tapered portion 21a slides on the upper corner portion of the wall surface portion 201a in the vertical direction.

Further, the joint member 21 is formed so that its vertical length is longer than the vertical length of the floor body portion 25. The floor body 25 is housed in the projection plane of the joint member 21 when viewed from the horizontal direction. The tip portions 22a, 23a, and 24a of the floor body portion 25 are located closer to the frame 2 than the tapered portion 21a of the joint member 21.

Further, the tread plate member 22, the reinforcing member 23, and the bracket member 24 constituting the floor body portion 25 have the tip portions 22a, 23a, and 24a stepwise in the width direction in correspondence with the inclination of the tapered portion 21a of the joint member 21. They are arranged so as to be offset in the orthogonal direction. As a result, the tip portions 22a, 23a, 24a of the floor body portion 25 do not protrude from the tapered portion 21a of the joint member 21 toward the wall surface portion 201a of the upper cradle 201B, and the tip portion of the floor body portion 25 is made into a joint member. It can be stored in 21.

Further, by arranging the tread plate member 22, the reinforcing member 23, and the bracket member 24 in a staggered manner, the tip portion 22a of the tread plate member 22 can be brought closer to the wall surface portion 201a, and between the floor body portion 25 and the wall surface portion 201a. The resulting gap can be reduced.

As described above, the joint member 21 is the only member to be tapered. As a result, it is possible to reduce the time and effort required to manufacture the upper floor 4B, which is a slide floor, and it is possible to reduce the manufacturing cost.

1-3. Example of Moving the Upper Floor (Sliding Floor) Next, the moved state of the upper floor 4B having the above-described configuration will be described with reference to FIG.
FIG. 5 is a cross-sectional view showing a state in which the upper floor 4B has moved.

When the distance between the lower floor 200A and the upper floor 200B is narrowed due to interlayer displacement due to seismic motion and various vibrations, the distance between the frame 2 and the upper pedestal 201B is also narrowed. At this time, as shown in FIG. 4, the support angle 9 slides in the direction approaching the upper cradle 201B by the slide member 9a. As a result, the upper boarding / alighting floor 4B supported by the frame 2 and the support angle 9 slides.

Since the upper boarding / alighting floor 4B slides toward the wall surface portion 201a of the upper cradle 201B, the tip end portion of the upper boarding / alighting floor 4B abuts on the wall surface portion 201a. Further, the tapered portion 21a of the joint member 21 abuts on the wall surface portion 201a and slides so as to climb the upper end side corner portion of the wall surface portion 201a in the vertical direction. Then, the tapered portion 21a rides on the finished floor surface 203 side from the upper cradle 201B.

Further, the floor body portion 25 arranged between the pair of joint members 21 and 21 also rides on the finished floor surface 203 side from the upper cradle 201B together with the joint members 21. As a result, the entire upper floor 4B rides on the finished floor surface 203 side. As a result, it is possible to prevent the upper boarding / alighting floor 4B and the upper pedestal 201B from being damaged by being compressed by the frame 2 and the upper pedestal 201B.

As described above, the tip portion of the floor body portion 25 is located closer to the frame 2 than the tapered portion 21a of the joint member 21. Therefore, it is possible to prevent the floor body portion 25 from coming into contact with the finished floor surface 203 or the corner portion of the upper cradle 201B when riding on the finished floor surface 203 side. As a result, it is possible to prevent the tread plate member 22, the reinforcing member 23, and the bracket member 24 constituting the floor body portion 25 from being damaged.

After that, when the distance between the lower floor 200A and the upper floor 200B is widened due to further interlayer displacement, the tapered portion 21a of the joint member 21 slides down the corner portion of the wall surface portion 201a, and the upper floor 4B gets on and off. , Return to the upper cradle 201B shown in FIG.

2. 2. Example of Second Embodiment Next, an example of the second embodiment of the passenger conveyor will be described with reference to FIG.
FIG. 6 is an enlarged cross-sectional view showing the tip end portion of the slide floor in the passenger conveyor according to the second embodiment.

The difference between the passenger conveyor according to the second embodiment and the passenger conveyor according to the first embodiment is the shape of the joint member of the slide floor. Therefore, here, the configuration of the joint member will be described, and the same reference numerals will be given to the parts common to the passenger conveyor according to the first embodiment, and duplicate description will be omitted.

As shown in FIG. 6, the upper floor boarding / alighting floor 34B showing the slide floor has a joint member 31 and a floor body portion 25. The floor body portion 25 is configured by laminating the tread plate member 22, the reinforcing member 23, and the bracket member 24, similarly to the floor body portion 25 according to the first embodiment. Joint members 31 are fixed to both ends of the floor body 25 in the width direction.

A tapered portion 31a, which is an inclined surface portion, and an end surface portion 31b are formed at the tip end portion of the joint member 31. The end face portion 31b is formed at the upper end portion in the vertical direction at the tip end portion of the joint member 31. The end face portion 31b is substantially parallel to the vertical direction. The end face portion 31b projects on the same plane as the tip portion 22a of the tread plate member 22 in the floor body portion 25, or on the wall surface portion 201a (see FIG. 3) side of the tip portion 22a of the tread plate member 22. Further, the vertical length of the end face portion 31b is set to be the same as or slightly longer than the vertical length of the tread plate member 22.

A tapered portion 31a is continuously formed from the lower end of the end face portion 31b in the vertical direction. That is, in the upper boarding / alighting floor 34B according to the second embodiment, only a part of the tip portion of the joint member 31 is inclined.

Further, the floor body portion 25 does not project from the tapered portion 31a and the end surface portion 31b toward the wall surface portion 201a (see FIG. 3). That is, the floor main body 25 is housed in the projection plane of the joint member 31 when viewed from the horizontal direction.

Here, the tread plate member 22 is formed to be relatively thinner than the other members. Therefore, the length of the tread plate member 22 and the end face portion 31b having substantially the same length in the vertical direction is relatively short. Then, when an interlayer displacement occurs and the upper boarding / alighting floor 34B approaches the wall surface portion 201a of the upper cradle 201B, the end surface portion 31b of the joint member 31 comes into contact with the wall surface portion 201a. However, since the length of the end face portion 31b in the vertical direction is set to be relatively short, the end face portion 31b immediately rides on the corner portion of the wall surface portion 201a, and the tapered portion 31a comes into contact with the corner portion of the wall surface portion 201a. .. As described above, even in the joint member 31 in which only a part of the lower side of the tip portion is inclined, the same operation and effect as in the first embodiment can be obtained.

Further, by arranging the end surface portion 31b of the joint member 31 at substantially the same position as the tip portion 22a of the tread plate member 22, the gap generated between the floor body portion 25 and the wall surface portion 201a of the upper cradle 201B is reduced. be able to.

Since other configurations are the same as those of the passenger conveyor 1 according to the first embodiment described above, the description thereof will be omitted. Even in the passenger conveyor having the upper boarding / alighting floor 34B having such a configuration, the same operations and effects as those of the passenger conveyor 1 according to the above-described first embodiment can be obtained.

It should be noted that the embodiment is not limited to the embodiment described above and shown in the drawings, and various modifications can be carried out within a range that does not deviate from the gist of the invention described in the claims.

In the above-described embodiment, the escalator in which a step is generated between the steps is described as an example of the inclined passenger conveyor, but the passenger conveyor of the present invention has a plurality of steps in which a step is not generated between the steps. It can also be applied to electric roads, so-called moving walkways.

The present invention can also be applied to a passenger conveyor having a frame in which at least a part of the intermediate inclined portion 2C is provided with a portion parallel to the lower floor horizontal portion 2A and the upper floor horizontal portion 2B. Further, the present invention is the same for a passenger conveyor having a frame in which the extending directions of the intermediate inclined portion 2C are curved and changed so that the extending directions of the lower floor horizontal portion 2A and the upper floor horizontal portion 2B are different. It can be applied to.

Further, although it has been explained that the upper boarding / alighting floor 4B is a sliding floor, the present invention is not limited to this. For example, when the lower floor side of the passenger conveyor 1 is a free end, the lower boarding / alighting floor 4A is a sliding floor. When the lower boarding / alighting floor 4A is a sliding floor, the configuration thereof is the same as the configuration of the upper boarding / alighting floor 4B described above, and thus the description thereof will be omitted.

Further, in the above-described embodiment, the example in which the upper floor 4B indicating the slide floor is fixed to the support angle 9 has been described, but the present invention is not limited to this, and for example, the upper floor 4B is attached to the frame 2. It may be fixed.

Although words such as "parallel" and "orthogonal" have been used in the present specification, these do not mean only strict "parallel" and "orthogonal", but include "parallel" and "orthogonal". Further, it may be in a "substantially parallel" or "substantially orthogonal" state within a range in which the function can be exhibited.
