[0038] The embodiments will be described with reference to the accompanying drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and the repeated description of the parts will be appropriately simplified or omitted.

[0039] Implementation Method 1

[0040] Figure 1 This is a perspective view of the passenger conveyor in Embodiment 1.

[0041] Figure 1 The passenger conveyor is an escalator. Figure 1In the present invention, a landing floor 1 is provided on each floor of a building. A plurality of steps 2 are connected in a ring shape. The steps 2 are arranged so as to be able to circulate between the entrance and exit floor of the upper floor and the entrance and exit floor of the lower floor. A pair of handrails 3 are provided on both sides of the steps in the width direction along the direction of movement of the steps 2. A pair of handrails 4 are provided along the outer periphery of each of the pair of handrails 3. The pair of handrails 4 are arranged so as to be able to move synchronously with the plurality of steps. A pair of skirt panels 5 are provided below each of the pair of handrails 3.

[0042] Next, use Figure 2 and Figure 3 Step 2 will be described.

[0043] Figure 2 This is a perspective view of the steps of the passenger conveyor in the first embodiment. Figure 3 This is a perspective view of the main part of the steps of the passenger conveyor in the first embodiment.

[0044] like Figure 2 As shown, the steps 2 include a tread 6 , a riser 7 , and a pair of triangular brackets 8 .

[0045] The step 6 is a board for the user to ride on. The riser 7 is kicked up. A pair of triangular brackets 8 are arranged to be separated in the width direction of the step 6. The pair of triangular brackets 8 respectively support one end and the other end of the step 6 and the riser 7 in the width direction.

[0046] The support member 9 is provided at the end portion of the triangular bracket 8 on the side opposite to the riser 7. The support member 9 is formed of aluminum, for example.

[0047] like Figure 3 As shown, the axial direction of the support member 9 is set to the width direction of the step 2. For example, the support member 9 is formed into a cylindrical shape. The support member 9 is provided so that the amount of protrusion from the step 2 is within a predetermined range.

[0048] A pair of guide grooves (not shown) are formed on the inner wall of the support member 9 so as to face each other with the axis of the support member 9 interposed therebetween. A pair of guide grooves are formed so as to extend parallel to the axis. A pair of insertion holes 10 are formed on the peripheral wall of the support member 9 so as to connect the pair of guide grooves with the outside of the support member 9. Figure 3 , only one insertion hole 10 is shown. A pair of fitting grooves 11 are formed at the ends of the support body so as to face each other with the axis of the support member 9 interposed therebetween. The relative direction of the pair of fitting grooves 11 is perpendicular to the relative direction of the pair of guide grooves.

[0049] The guide shoe 12 functions as a step guide device together with the support member 9. The guide shoe 12 is formed of, for example, a resin material and includes a contact portion 13 and a protruding portion 14.

[0050] The contact portion 13 is a portion that contacts the skirt plate 5 when the step 2 moves. For example, the contact portion 13 is formed in a rectangular parallelepiped shape. The protrusion 14 protrudes from the contact portion 13 toward the step 2. The protrusion 14 is housed in the support member 9.

[0051] For example, the protrusion 14 includes a pair of legs 15. A pair of claws 16 protrude outward from the protruding ends of the legs 15 in the direction in which the legs 15 face each other. A pair of protrusions 17 are provided so as to be engageable with the pair of engagement grooves 11. The protrusions 17 are provided on the back surface of the contact portion 13 at a central position between the legs 15.

[0052] When the guide shoe 12 is mounted on the step 2, the pair of claws 16 are inserted into the pair of guide grooves. At this point, the pair of legs 15 are elastically deformed. In this state, the pair of claws 16 advance along the pair of guide grooves. When the pair of claws 16 reach the pair of insertion holes 10, the pair of legs 15 are released from elastic deformation. As a result, the pair of claws 16 are inserted into the interior of the pair of insertion holes 10. At this point, the pair of protrusions 17 are inserted into the pair of fitting grooves 11. As a result, the guide shoe 12 is mounted on the step 2 with the contact portion 13 facing outward in the width direction of the tread 6.

[0053] Next, use Figure 4 and Figure 5 , the relationship between the support component and the guide shoe is explained.

[0054] Figure 4 and Figure 5 This is a diagram for explaining the relationship between the support member and the guide shoe of the passenger conveyor in the first embodiment.

[0055] like Figure 4 and Figure 5 As shown, the support member 9 functions as a support body for the guide shoe 12. The support member 9 contacts the surface of the guide shoe 12 opposite the contact surface with the skirt plate 5. At this point, the support member 9 contacts the back surface of the contact portion 13 of the guide shoe 12, ensuring a distance of at least 90% of the length of the contact surface of the guide shoe 12 in the sliding direction. Specifically, the outer diameter b of the support member 9 is set to at least 90% of the length B of the contact surface of the guide shoe 12 in the sliding direction with the skirt plate 5.

[0056] Next, use Figure 6 A sliding experiment of the guide shoe will be described.

[0057] Figure 6 It is a figure for demonstrating the sliding test of the guide shoe of the passenger conveyor in Embodiment 1.

[0058] The drive shaft 18 is attached to a rotating shaft of a motor (not shown), etc. The drive shaft 18 is disposed separately from the test skirt 5. The driven shaft 19 is disposed separately from the drive shaft 18. Like the drive shaft 18, the driven shaft 19 is disposed separately from the skirt 5. The belt 20 is formed into an endless shape. The belt 20 is wound around the drive shaft 18 and the driven shaft 19. A retaining member 21 is attached to the test skirt 5 side of the belt 20.

[0059] The guide shoe 12 is mounted on the retaining member 21 in a state where the contact portion 13 is in contact with the test skirt 5. The thickness of the contact portion 13 at this time is set to 7 mm, which is a general thickness. The accelerometer 22 is mounted on the side of the contact portion 13 of the guide shoe 12. The guide shoe 12 is pressed against the skirt 5 with a force F. In this state, the drive shaft 18 rotates, whereby the guide shoe 12 moves at a speed V in a state where the surface of the contact portion 13 is in contact with the skirt 5. The values ​​of the force F and the speed V at this time are set to the same values ​​as when the guide shoe 12 is used in an actual passenger conveyor. At this time, a computing terminal not shown collects the acceleration information obtained by the accelerometer 22. The computing terminal displays the acceleration information.

[0060] Next, use Figure 7 The results of the sliding test of the guide shoe will be described.

[0061] Figure 7 It is a figure for demonstrating the result of the sliding test of the guide shoe of the passenger conveyor in Embodiment 1.

[0062] like Figure 7 The parameter shown in the lower section is the "seat ratio." The "seat ratio" is defined by b / B. In the sliding experiment, B is fixed. By changing b, the "seat ratio" changes.

[0063] When the "seat ratio" was 50%, sliding noise was observed. When the "seat ratio" was 80%, sliding noise was observed. When the "seat ratio" was 90%, no sliding noise was observed. When the "seat ratio" was 100%, no sliding noise was observed.

[0064] Figure 7 The left side of the upper section shows the detection result of the accelerometer 22 when sliding noise is confirmed. Figure 7 As shown on the left side of the upper section, when sliding noise is confirmed, friction vibration is also confirmed.

[0065] Figure 7 The right side of the upper section shows the detection result of the accelerometer 22 when no sliding noise is confirmed. Figure 7 As shown on the right side of the upper section, no sliding noise was observed, and no friction vibration was observed either.

[0066] In addition, the presence or absence of friction vibration is determined based on whether the vibration amplitude exceeds a preset value.

[0067] According to the first embodiment described above, the support member 9 supports the guide shoe 12 while maintaining contact with the surface of the guide shoe 12 opposite the contact surface with the skirt panel 5, ensuring a distance of at least 90% of the length of the guide shoe 12's contact surface in the sliding direction. Under these conditions, the guide shoe 12 maintains a torque corresponding to the frictional force it receives from the skirt panel 5. This suppresses pitching motion of the skirt panel 5. Consequently, sliding noise can be suppressed during long-term operation of the passenger conveyor.

[0068] The cross-sectional shape of the support member 9 is not limited. For example, the cross-sectional shape of the support member 9 may be circular, rectangular, square, or elliptical.

[0069] The shape of the contact portion 13 of the guide shoe 12 is not limited. For example, the shape of the contact portion 13 of the guide shoe 12 may be circular, rectangular, square, or elliptical.

[0070] Next, use Figure 8 and Figure 9 , a first modification example of the guide shoe is described.

[0072] like Figure 8 and Figure 9 As shown, the support member 9 is formed into a square cylindrical shape. In this case, the support member 9 contacts the back surface of the contact portion 13 of the guide shoe 12, ensuring a distance of at least 90% of the sliding length of the contact surface of the guide shoe 12 with the skirt plate 5. Specifically, the length b of the support member 9 in the sliding direction is set to at least 90% of the length B of the contact surface of the guide shoe 12 with the skirt plate 5 in the sliding direction. This also suppresses frictional vibration. As a result, sliding noise can be suppressed during long-term operation of the passenger conveyor.

[0073] Next, use Figure 10 and Figure 11 , a second modification example of the guide shoe is described.

[0074] Figure 10 and Figure 11 It is a diagram for explaining a second modified example of the guide shoe of the passenger conveyor in the first embodiment.

In this case, the support member 9 contacts the back surface of the contact portion 13 of the guide shoe 12, ensuring a distance of at least 90% of the length of the contact surface of the guide shoe 12 in the sliding direction with the skirt panel 5. Specifically, the larger outer diameter b of the support member 9 is set to at least 90% of the length B of the contact surface of the guide shoe 12 in the sliding direction with the skirt panel 5. This also suppresses frictional vibration. As a result, sliding noise can be suppressed during the long-term operation of the passenger conveyor.

[0076] Next, use Figure 12 and Figure 13 , a third modification example of the guide shoe is described.

[0077] Figure 12 and Figure 13 It is a diagram for explaining a third modified example of the guide shoe of the passenger conveyor in the first embodiment.

The pair of contact members 23 are in contact with the surface of the guide shoe 12 on the opposite side of the contact surface with the skirt 5, ensuring a distance of more than 90% of the length of the contact surface of the guide shoe 12 in the sliding direction. In this case, friction vibration is also suppressed. As a result, sliding noise can be suppressed during long-term operation of the passenger conveyor. Moreover, the material cost and weight of the step guide device can be suppressed. In addition, even in a case where it is difficult to replace the support member 9 in the existing passenger conveyor, the desired "seat surface ratio" can be ensured.

[0079] Next, use Figure 14 and Figure 15 , a fourth modification example of the guide shoe is described.

Specifically, the outer diameter b of the contact member 23 is set to more than 90% of the length B of the contact surface of the guide shoe 12 in the sliding direction in contact with the skirt board 5. In this case, friction vibration is also suppressed. As a result, sliding noise can be suppressed during long-term operation of the passenger conveyor. Moreover, even in a case where it is difficult to replace the support member 9 in the existing passenger conveyor, it is easier to ensure the desired "seat surface ratio".

[0085] Next, use Figure 18 and Figure 19 , a sixth modification example of the guide shoe is described.

[0086] Figure 18 and Figure 19 It is a diagram for explaining a sixth modified example of the guide shoe of the passenger conveyor in the first embodiment.

[0087] like Figure 18 and Figure 19 As shown, the pair of contact members 23 are bolts. The pair of contact members 23 function as a support body together with the support member 9. The pair of contact members 23 are screwed into the direction of the contact surface of the guide shoe 12 that contacts the skirt board 5 relative to the pair of threaded hole portions connected to the side of the support member 9. The pair of contact members 23 are in contact with the surface of the guide shoe 12 opposite to the contact surface of the guide shoe 12 that contacts the skirt board 5 for a distance of more than 90% of the length in the sliding direction of the contact surface of the guide shoe 12 that contacts the skirt board 5. In this case, friction vibration is also suppressed. As a result, sliding noise can be suppressed during long-term operation of the passenger conveyor. Moreover, the pair of contact members 23 can be reliably in contact with the surface of the guide shoe 12 opposite to the contact surface of the guide shoe 12 that contacts the skirt board 5. As a result, a stable pressing reaction force can be obtained.

[0088] Next, use Figure 20 and Figure 21 , the seventh modification example of the guide shoe is described.

The pair of contact members 23 are respectively connected to the side surfaces of the step 2. The pair of contact members 23 function as a supporting body together with the support member 9. The pair of contact members 23 are in contact with the surface of the guide shoe 12 on the opposite side of the contact surface with the skirt board 5, ensuring a distance of more than 90% of the length of the contact surface of the guide shoe 12 in the sliding direction. In this case, friction vibration is also suppressed. As a result, sliding noise can be suppressed during long-term operation of the passenger conveyor. Moreover, the pair of contact members 23 can be reliably in contact with the surface of the guide shoe 12 on the opposite side of the contact surface with the skirt board 5. As a result, a stable pressing reaction force can be obtained.

[0091] Next, use Figure 22 and Figure 23 , an eighth modification example of the guide shoe is described.

[0093] like Figure 22 and Figure 23 As shown, the contact member 23 is cylindrically shaped. It is connected to the side surface of the support member 9. Together with the support member 9, the contact member 23 functions as a support structure. The pair of contact members 23 maintains contact with the surface of the guide shoe 12 opposite the contact surface with the skirt 5, ensuring a distance of at least 90% of the length of the contact surface of the guide shoe 12 in the sliding direction. Specifically, the outer diameter b of the contact member 23 is set to at least 90% of the length B of the contact surface of the guide shoe 12 in the sliding direction. A pair of auxiliary elastic members 24 function as part of the support structure. The pair of auxiliary elastic members 24 are respectively disposed between the side surface of the step 2 and the contact member 23. The pair of auxiliary elastic members 24 press the contact member 23 against the surface of the guide shoe 12 opposite the contact surface with the skirt 5. This also suppresses frictional vibration. As a result, sliding noise can be suppressed during the long-term operation of the passenger conveyor.

[0094] Next, use Figure 24 and Figure 25, a ninth modification example of the guide shoe is described.
