Embodiment 1 FIG.
FIG. 1 is a cross-sectional view illustrating an example of a passenger conveyor according to the first embodiment. FIG. 1 shows an escalator as an example of a passenger conveyor. Description of other examples of the passenger conveyor such as a moving sidewalk is omitted. FIG. 2 is an enlarged view of a portion A in FIG. FIG. 3 is a view of part A of FIG. 1 as viewed from above.

トラス The escalator truss 1 spans the upper and lower floors. The truss 1 supports the escalator's own weight and the loaded load. A machine room 2 and a machine room 3 are formed inside the truss 1. In the example shown in FIG. 1, the machine room 2 is formed below the entrance 4. The machine room 3 is formed below the entrance 5.

For example, a control device 6, a drive device 7, a sprocket 8, and a pair of sprockets 9 are provided in the machine room 2. A pair of sprockets 10 are provided in the machine room 3. In the following, one of the sprockets 9 will be described as a sprocket 9a and the other will be described as a sprocket 9b. Similarly, one of the sprockets 10 is referred to as a sprocket 10a, and the other is referred to as a sprocket 10b.

The control device 6 controls the drive device 7. The drive chain 11 is wound around the output shaft of the drive device 7 and the sprocket 8. The escalator includes a pair of step chains 12. In the following, one of the step chains 12 is referred to as a step chain 12a, and the other is referred to as a step chain 12b.

The step chain 12a is endless. The step chain 12a is wound around the sprocket 9a and the sprocket 10a. The step chain 12b is endless. The step chain 12b is wound around the sprocket 9b and the sprocket 10b.

多数 A large number of step shafts 13 are provided at equal intervals between the

step chains

12a and 12b. Each step shaft 13 is arranged to be orthogonal to the

step chains

12a and 12b in design. Each step shaft 13 is provided with a step 14 for passengers to get on.

すると When the output shaft of the drive device 7 rotates, the sprocket 8 rotates via the drive chain 11. The sprocket 9a and the sprocket 9b are linked to the sprocket 8. When the sprocket 9a rotates, the step chain 12a moves. When the sprocket 9b rotates, the step chain 12b moves. That is, the driving device 7 moves the step shaft 13 and the step 14 via the step chain 12a and the step chain 12b.

Step 14 is circulated between the entrance 4 and the entrance 5 by being pulled by the

step chains

12a and 12b. The escalator includes a pair of skirt guards 15. In the following, one of the skirt guards 15 is described as a skirt guard 15a, and the other is described as a skirt guard 15b. The skirt guard 15a and the skirt guard 15b are arranged above the step shaft 13 so as to face each other. The passenger gets on step 14 moving between the skirt guard 15a and the skirt guard 15b. In the following, as shown in FIG. 2, the upper and lower sides of step 14 are specified based on the direction of step 14 in which the passenger gets on.

Step 14 includes, for example, a tread plate 20, a support frame 21, a riser 22, a pair of rollers 23, a guide 24, and a guide 25. Hereinafter, one of the rollers 23 is described as a roller 23a and the other is described as a roller 23b. In FIG. 3, a part of the step board 20 is omitted.

The passenger gets on the upper surface 20a of the tread plate 20. In addition, an end surface 20b and an end surface 20c orthogonal to the upper surface 20a are formed on the tread plate 20. The end face 20b faces the skirt guard 15a. A gap is formed between the end face 20b and the skirt guard 15a. The end face 20c faces in a direction opposite to the end face 20b. The end face 20c faces the skirt guard 15b. A gap is formed between the end face 20c and the skirt guard 15b.

The tread plate 20 is fixed to the support frame 21. The tread plate 20 is arranged so as to cover the support frame 21 from above. That is, the support frame 21 supports the tread plate 20 from below. Part of the support frame 21 faces the skirt guard 15a. The portion of the support frame 21 facing the skirt guard 15a does not project from the end face 20b when viewed from above. Another part of the support frame 21 faces the skirt guard 15b. The portion of the support frame 21 facing the skirt guard 15b does not project from the end face 20c when viewed from above. The support frame 21 is provided on the step shaft 13.

The riser 22 is fixed to the support frame 21. The riser 22 is a curved plate-shaped member. The riser 22 is disposed so as to extend downward from the edge of the step board 20.

The roller 23a and the roller 23b are rotatably provided on the support frame 21. The escalator includes a pair of rails 16 and a pair of rails 17. In the following, one of the rails 16 is referred to as a rail 16a, and the other is referred to as a rail 16b. Similarly, one of the rails 17 is referred to as a rail 17a, and the other is referred to as a rail 17b. The roller 23a rolls on the rail 16a. The roller 23b rolls on the rail 16b. Further, as shown in FIGS. 2 and 3, a number of rollers 18a are rotatably provided on the step chain 12a. A number of rollers 18b are rotatably provided on the step chain 12b. The roller 18a rolls on the rail 17a. The roller 18b rolls on the rail 17b. The attitude of the step 14 is controlled by the pair of rails 16 and the pair of rails 17.

The guide 24 is provided on the support frame 21. The guide 24 is arranged below the step board 20. The guide 24 is arranged so as to face the skirt guard 15a.

The guide 25 is provided on the support frame 21. The guide 25 is arranged below the step board 20. The guide 25 is arranged to face the skirt guard 15b.

FIG. 4 is an enlarged view of part B of FIG. The guide 24 has a convex portion 26. The protrusion 26 is made of, for example, resin. The projection 26 projects from the end surface 20 b of the tread plate 20 when viewed from above. That is, the convex portion 26 is disposed at a position closer to the skirt guard 15a than the tread plate 20. A gap is formed between the protrusion 26 and the skirt guard 15a. The gap between the protrusion 26 and the skirt guard 15a is smaller than the gap between the end face 20b and the skirt guard 15a. For example, a part of the convex portion 26 is disposed immediately above the step shaft 13.

The symbol C is the center point of the step axis 13. The surface 26a of the central portion of the convex portion 26 is a part of the surface of the sphere S centered on the center point C. The symbol R is the radius of the sphere S. The convex portion 26 is disposed, for example, entirely inside the sphere S.

FIG. 5 is an enlarged view of a portion D in FIG. The guide 25 has a convex portion 27. The protrusion 27 is made of, for example, resin. The protrusion 27 projects from the end face 20 c of the tread plate 20 when viewed from above. That is, the protrusion 27 is disposed at a position closer to the skirt guard 15b than the tread plate 20. A gap is formed between the protrusion 27 and the skirt guard 15b. The gap between the protrusion 27 and the skirt guard 15b is smaller than the gap between the end face 20c and the skirt guard 15b. For example, a part of the convex portion 27 is disposed immediately above the step shaft 13.

形状 The shape of the protrusion 27 is the same as the shape of the protrusion 26. The surface 27a at the center of the projection 27 is another part of the surface of the sphere S centered on the center point C. The convex portion 27 is disposed, for example, entirely inside the sphere S.

As described above, in the escalator, the step 14 is moved by being pulled by the

step chains

12a and 12b. The length of the step chain 12a does not always match the length of the step chain 12b. For example, the length of the step chain 12a varies depending on assembly errors and aging. The length of the step chain 12b varies depending on assembly errors and aging. Therefore, the step axis 13 may be inclined with respect to the traveling direction of the step 14. When the step shaft 13 tilts, the step 14 also tilts.

In the example shown in the present embodiment, the surface 26a of the projection 26 is a part of the surface of the sphere S centered on the center point C. The surface 27a of the projection 27 is a part of the surface of the sphere S centered on the center point C. Therefore, even if the step 14 is inclined, the width W of the step 14 does not change. The width W is a width in a direction orthogonal to the traveling direction of step 14 and in a horizontal direction. Therefore, for example, even if the guide 24 contacts the skirt guard 15a, the guide 24 is not excessively pressed against the skirt guard 15a. Even if the guide 25 contacts the skirt guard 15b, the guide 25 is not excessively pressed against the skirt guard 15b. For this reason, the abnormal sound generated when the step 14 is tilted can be reduced.

In the present embodiment, an ideal example in which the center of the sphere S is the center point C of the step axis 13 has been described. This is an example. The center of the sphere S may be shifted from the center point C of the step axis 13. For example, the center of the ball S may be a specific point C ′ (not shown) immediately below the tread plate 20. However, it is preferable that the point C ′ is closer to the center point C. In such a case, the distance from the point C 'to the surface 26a of the central portion of the convex portion 26 becomes a constant value. Similarly, the distance from the point C ′ to the surface 27a of the central portion of the convex portion 27 becomes the above-mentioned constant value. Even in such an example, a certain effect can be expected.

In the present embodiment, an example has been described in which the surface 26a is a part of the surface of the sphere S and the surface 27a is another part of the surface of the sphere S. This is an example. The surface 26a may be a part of the surface of the cylinder, and the surface 27a may be another part of the surface of the cylinder. In this example, the guide 24 and the guide 25 can be easily manufactured. In such a case, the cylinder for forming the surface 26a and the surface 27a is, for example, a cylinder whose center line is a straight line passing through the center point C and orthogonal to the tread plate 20.

円 Note that a cylinder whose center line is a straight line passing through the center point C and orthogonal to the tread plate 20 is an ideal example. The center line of the cylinder for forming the surface 26a and the surface 27a may be shifted from the center point C of the step shaft 13. For example, the center line of the cylinder may be a specific straight line orthogonal to the tread plate 20. However, it is preferable that the specific straight line is closer to a straight line passing through the center point C. In such a case, the distance from the specific straight line to the surface 26a of the central portion of the convex portion 26 has a constant value. Similarly, the distance from the specific straight line to the surface 27a of the central portion of the convex portion 27 has the constant value. Even in such an example, a certain effect can be expected.

As another example, the cylinder for forming the surface 26a and the surface 27a may be a cylinder having a center line about a straight line F orthogonal to the plane E as shown in FIG. The plane E is a plane that includes the center line of the step axis 13 and is parallel to the moving direction of the step axis 13. The moving direction of the step shaft 13 is equal to the traveling direction of the step 14. Ideally, the straight line F passes through the center point C of the step axis 13. However, the straight line F does not have to pass through the center point C. The straight line F is preferably as close to the straight line passing through the center point C as possible. When the straight line F passes through the center point C, the distance from the straight line F to the surface 26a at the center of the convex portion 26 becomes a constant value. Similarly, the distance from the straight line F on the surface 27a of the central portion of the convex portion 27 has the above-mentioned constant value.

The present invention is applicable to, for example, a passenger conveyor provided with a skirt guard.
