[0012] Hereinafter, an embodiment of the passenger conveyor according to the present invention will be described. The passenger conveyor described here is applied to the embodiments of the steps and demarcation described later.

[0013] Passenger conveyors include escalators, which form a height difference between the steps as they move circulating between the boarding and alighting floors at both ends, and powered walkways (moving walkways), which form no height difference. In this embodiment, an escalator will be used as an example of a passenger conveyor, but the present invention can also be applied to other passenger conveyors such as powered walkways.

[0014] Furthermore, no particular distinction will be made between the names of the components that make up an escalator and an electric walkway. For example, the steps described in this embodiment are generally called steps in escalators, but may be called pallets in electric walkways. The steps used in the following description are not limited to escalator steps, but also include electric walkway pallets.

[0015] FIG. 1 is a perspective view of a main part of a passenger conveyor 100 according to an embodiment of the present invention. The passenger conveyor 100 of this embodiment comprises a boarding and alighting floor 1 installed on the floor surface of each floor of the building, a plurality of steps 2 that are endlessly connected and move in a circular motion between the boarding and alighting floor 1 on the lower floor and the boarding and alighting floor 1 on the upper floor, balustrades 3 arranged on both sides (left and right sides) of the steps 2 in the direction of movement of the steps 2, a moving handrail 4 supported by the balustrades 3 and moving in a circular motion in synchronization with the steps 2, an inner deck 5A and a skirt guard 5B that cover the inside of the lower part of the balustrade 3, and an outer deck 5C that covers the outside of the lower part of the balustrade 3.

[0016] In this specification, the width direction of the step 2 is defined as the direction indicated by W in Fig. 1, and the depth direction of the step 2 is defined as the direction indicated by D in Fig. 1. When simply referring to the width direction or depth direction, it means the width direction W or depth direction D of the step 2. In this case, the up-down direction is the direction perpendicular to the tread surface of the step 2, and is the direction perpendicular to the width direction W and depth direction D. Furthermore, the sides (both sides) of the step 2 mean the sides (both sides) in the width direction W, and the side ends (both side ends) mean the ends of the step 2 or cleat 2D (see Fig. 2) in the width direction W.

[0017] [Example 1] The structure of the steps 2 of the passenger conveyor 100 will be described with reference to Fig. 2. Fig. 2 is a perspective view of the steps 2 of the passenger conveyor 100 according to one embodiment of the present invention.

[0018] Step 2 is cleat 2D and riser 2 The cleat 2D is uneven and is provided on the surface (upper surface) of the step 2 to form the tread surface. 2 E is uneven and is configured at the riser (the part that forms the step of the step 2). The triangular bracket 2F is connected to the cleat 2D and riser 2 E is a component that secures

[0019] The cleat 2D is surrounded on all four sides by a side end demarcation 2A, a front end demarcation 2B, and a rear end demarcation 2C. Each of the demarcations 2A, 2B, and 2C also has an uneven surface on the top surface.

[0020] The side end demarcations 2A are arranged on both side ends of the cleat 2D. When the circulating step 2 moves upward, the front end demarcation 2B is arranged at the end of the cleat 2D opposite the riser 2E side, i.e., at the front end (end on the upper floor side) of the cleat 2D. The rear end demarcation 2C is arranged at the end of the cleat 2D on the riser 2E side, i.e., at the rear end (end on the lower floor side) of the cleat 2D. The demarcations 2A, 2B, and 2C are colored in a highly distinctive color that is different from the color of the tread surface of the cleat 2D.

[0021] If the direction of movement is used as the reference, the front-to-back direction of the steps 2 will also be reversed if the direction of circular movement of the steps 2 is reversed, but in this embodiment, the front-to-back direction of the steps 2 is defined based on the case where the steps 2 move in an upward direction. The front-to-back direction of the steps 2 coincides with the depth direction D.

[0022] The steps 2 may be made of aluminum molding material, and the cleats 2D, risers 2E, and triangular brackets 2F may be integrally molded from aluminum. In this embodiment, it does not matter whether the cleats 2D, risers 2E, and triangular brackets 2F are integrally molded or are separate components.

[0023] Fig. 3 is a diagram showing the cross-sectional structure of a side end demarcation 2A formed of a laminated structure. Fig. 4 is a perspective view of the side end demarcation 2A according to one embodiment of the present invention. Fig. 3 shows the shape of the side end demarcation 2A as viewed from the depth direction D.

[0024] The demarcations 2A, 2B, and 2C in this embodiment are constructed as a laminated structure. The laminated structure can be formed, for example, by stacking materials using a 3D printer. In this embodiment, the laminated structure is constructed as shown by the arrow L in FIG. 3. This stacking direction coincides with the vertical direction when the demarcations 2A, 2B, and 2C are attached to the steps 2.

[0025] Each of the demarcations 2A, 2B, and 2C can be formed in the same manner using a laminated structure. The following describes the side end demarcation 2A. The side end demarcation 2A faces the skirt guard 5B and has a side surface (sliding surface) that slides against the skirt guard 5B.

[0026] When forming a laminated structure using a 3D printer, the size of the laminated structure that can be formed is limited by the size of the 3D printer. In this embodiment, taking into consideration the use of a small 3D printer, the side end demarcation 2A has a structure (a divided structure) divided into multiple parts in its longitudinal direction. In particular, in this embodiment, the side end demarcation 2A is divided into two members (side end demarcation members) 2AA, 2AB, which prevents an unnecessary increase in the number of parts. In other words, the side end demarcation 2A in this embodiment has a two-part structure.

[0027] The side end demarcation 2A has two members 2AA, 2AB each having a protrusion 2AA4, 2AB4 and a recess (groove) 2AA5, 2AB5. The side end demarcation member (first member) 2AA is provided with a protrusion 2AA6 that protrudes in the longitudinal direction of the side end demarcation 2A, and the side end demarcation member (second member) 2AB is provided with a recess 2AB6 that is recessed in the longitudinal direction of the side end demarcation 2A.

[0028] Projection 2AA 6 and recessed portion 2AB 6 The protrusions 2AA and 2AA are configured to be able to fit together and form a fitting portion. 6 and recessed portion 2AB 6 By fitting these together, the side end demarcation member 2AA and the side end demarcation member 2AB are assembled together. This makes it easy to align the projection 2AA4 and recess 2AA5 of the side end demarcation member 2AA with the projection 2AB4 and recess 2AB5 of the side end demarcation member 2AB. 6 and recessed portion 2AB 6 Between the side end demarcation member 2AA and the side end demarcation member 2AB in You can also swap them.

[0029] The side end demarcation member 2A of this embodiment is composed of laminated structures 2AA and 2AB in which materials are laminated. That is, the side end demarcation member 2AA and the side end demarcation member 2AB are composed of laminated structures.

[0030] This laminated structure 2AA (2AB) has an upper end surface 2AA1 (2AB1), a lower end surface 2AA3 (2AB3), and a side surface 2AA2 (2AB2). The upper end surface 2AA1 (2AB1) is formed by the upper end surface of the convex portion 2AA4 and is the tread surface on which passengers step. The lower end surface 2AA3 (2AB3) is the surface that rests on the cleat 2D. The side surface 2AA2 (2AB2) is the side surface of the laminated structures 2AA, 2AB that is located closest to the side end of the step 2. In addition, the side surface 2AA2 (2AB2) is the side surface that is located on the skirt guard 5B side, and in this embodiment, it faces the skirt guard 5B via a sliding member 2AC (see Figure 6) described later.

[0031] The laminated structures 2AA, 2AB are formed by stacking materials, and have smooth surfaces (layer formation surfaces) perpendicular to the stacking direction L. Therefore, the upper end surface 2AA1 (2AB1) and the lower end surface 2AA3 (2AB3), which are end surfaces in the stacking direction L of the laminated structures 2AA, 2AB, are also perpendicular to the stacking direction L and are formed as smooth planes.

[0032] On the other hand, unevenness occurs on the side surface 2AA2 (2AB2) which is the surface 21 along the stacking direction L. This is because slight unevenness occurs on the surface 21 along the stacking direction due to differences in the speed at which the material solidifies for each stacked layer. For this reason, the coefficient of friction of the side surface 1AA2 which is the surface 21 along the stacking direction L is greater than the coefficient of friction of the smooth end surfaces 2AA1, 2AA3.

[0033] Furthermore, the side end demarcations 2A, 2B, and 2C can be formed even if the stacking direction of the materials in the stacked structure 2AA (2AB) is set in a direction different from the direction L shown in Fig. 3. This will be described later.

[0034] 5 is a diagram according to one embodiment of the present invention, and is an enlarged view of the steps 2 and the skirt guard 5B and their vicinity, as viewed from the depth direction D in FIG.

[0035] There is a small gap δ between the step 2 and the side end demarcation 2A and the skirt guard 5B. If clothing or the like gets caught in this gap δ, there is a risk that it will get caught on the side end demarcation 2A and become difficult to remove.

[0036] As explained in Figure 3, the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB) has a large coefficient of friction due to the unevenness. If the laminated structure 2AA (2AB) is used as the side end demarcation 2A as is, the opposing surface of the side end demarcation 2A facing the skirt guard 5B becomes the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB). Therefore, clothing or the like that gets into the gap δ is likely to get caught on the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB), which has a large coefficient of friction.

[0037] FIG. 6 is a diagram showing a cross-sectional structure of a side end demarcation 2A according to one embodiment of the present invention. In this embodiment, a low-friction coefficient member (sliding member or low-friction coefficient member) 2AC, which is configured as a separate piece from the laminated structure 2AA (2AB) that constitutes the side end demarcation 2A, is attached to the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB). In this case, the friction coefficient of the sliding member 2AC is smaller than the friction coefficient of the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB). The low-friction coefficient sliding member 2AC is provided on the side of the side end demarcation 2A that faces the skirt guard 5B of the passenger conveyor 100.

[0038] Here, the side end demarcation 2A has a first surface 21 along the stacking direction L of the material. The side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB) is also included in the first surface 21. The side end demarcation 2A also includes a sliding member 2AC with a low coefficient of friction and has a second surface 22 composed of the sliding member 2AC. The friction coefficient of the second surface 22 is lower than that of the first surface 21, which has unevenness. Thus, in this embodiment, the first surface 21, which is one surface of the laminated structure 2AA (2AB) that constitutes the side end demarcation 2A, is used as a reference, and the second surface 22, which has a lower friction coefficient than the first surface 21, is provided on the side end demarcation 2A. The side end demarcation 2A is then positioned so that this second surface 22 faces the skirt guard 5B.

[0039] In Patent Document 1, fine irregularities are provided on the peaks of the cleats at the corners where the rear demarcation meets the riser, increasing the coefficient of friction at the corners. In contrast, this embodiment is characterized in that, based on a first surface 21 along the stacking direction L of the material, a second surface 22 with a lower coefficient of friction than this first surface 21 is provided on the side end demarcation 2A.

[0040] That is, in this embodiment, The demarcation (side end demarcation) 2A is composed of a laminated structure 2AA (2AB) in which materials are laminated, and has a first surface 21 along the lamination direction L of the materials and a second surface 22 having a smaller friction coefficient than the first surface 21, The demarcation 2A is arranged so that the second surface 22 is the surface facing the skirt guard 5B.

[0041] The side end demarcation 2A of this embodiment is configured so that at least two or more surfaces 21, 22 have different coefficients of friction. In other words, the side end demarcation 2A of this embodiment has at least two surfaces 21, 22 with different coefficients of friction.

[0042] [Change Example 1] In Example 1, a sliding member 2AC with a low friction coefficient was attached to the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB), thereby forming a second surface 22 with a lower friction coefficient than the first surface 21 in the side end demarcation 2A.

[0043] In this example, the sliding member 2AC of Example 1 is formed as a film with a low friction coefficient by a thin film forming method such as vapor deposition on the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB). Alternatively, the side surface 2AA2 (2AB2) of the laminated structure 2AA, 2AB, which has unevenness, may be polished to form the second surface 22 having a lower friction coefficient than the first surface 21. By using the polishing method, the second surface 22 can be formed by a simple process.

[0044] [Change Example 2] FIG. 7 is a diagram showing an embodiment of the division structure of the demarcation 2A to which the present invention is applied.

[0045] In this example, the fitting portion formed by the protrusion 2AA6 and the recess 2AB6 in the first embodiment is changed to a fitting portion in which stepped surfaces abut against each other.

[0046] The laminated structure 2AA has a stepped surface 2AA7 between the upper end surface 2AA1 and the lower end surface 2AA3, and further has a stepped surface 2AA8 between the upper end surface 2AA1 and the stepped surface 2AA7, and a stepped surface 2AA9 between the stepped surface 2AA7 and the lower end surface 2AA3.

[0047] The laminated structure 2AB has a stepped surface 2AB7 between an upper end surface 2AB1 and a lower end surface 2AB3, and further has a stepped surface 2AB8 between the upper end surface 2AB1 and the stepped surface 2AB7, and a stepped surface 2AB9 between the stepped surface 2AB7 and the lower end surface 2AB3.

[0048] An upper end surface 2AA1, a lower end surface 2AA3, and a stepped surface 2AA7 of the laminated structure 2AA, and an upper end surface 2AB1, a lower end surface 2AB3, and a stepped surface 2AB7 of the laminated structure 2AB constitute a fitting portion between the laminated structure 2AA and the laminated structure 2AB. The laminated structure 2AA and the laminated structure 2AB are fitted together and assembled integrally by matching the stepped surface 2AA7 of the laminated structure 2AA with the stepped surface 2AB7 of the laminated structure 2AB, butting the stepped surface 2AA8 of the laminated structure 2AA with the stepped surface 2AB8 of the laminated structure 2AB, and butting the stepped surface 2AA9 of the laminated structure 2AA with the stepped surface 2AB9 of the laminated structure 2AB.

[0049] In this case, it is preferable to fasten the laminated structure 2AA and the laminated structure 2AB by fastening a screw so as to penetrate the stepped surface 2AA7 and the stepped surface 2AB7.

[0050] In this embodiment, by abutting the stepped surface 2AA7 and the stepped surface 2AB7, the heightwise (vertical) alignment of the convex portion 2AA4 of the side end demarcation member 2AA and the convex portion 2AB4 of the side end demarcation member 2AB can be easily achieved.

[0051] Moreover, the side end demarcation 2A may have a cross section that is a simple plane and be divided into a laminated structure (side end demarcation member, first member) 2AA and a laminated structure (side end demarcation member, second member) 2AB.

[0052] [Example 2] FIG. 8 is a diagram showing a cross-sectional structure of a side end demarcation 2A according to one embodiment of the present invention.

[0053] In the laminated structure of Example 1, the stacking direction L of the material was vertical, whereas in the side end demarcation 2A of this example, the stacking direction of the material in the laminated structure is the direction shown by arrow L in Figure 7, and this stacking direction coincides with the width direction W of the step 2 (see Figure 1) when the side end demarcation 2A is assembled to the step 2.

[0054] in this case, 8, the first surface 21 along the stacking direction L of the material becomes the upper end surface 2AA1 (2AB1) or the lower end surface 2AA3 (2AB3) of the laminated structure 2AA (2AB), and the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB) becomes a surface perpendicular to the stacking direction L. Therefore, the upper end surface 2AA1 (2AB1) or the lower end surface 2AA3 (2AB3) becomes an uneven surface (first surface 21), and the friction coefficient of the side surface 2AA2 (2AB2) of the laminated structure 2AA (2AB) is smaller than the friction coefficient of the first surface 21. Therefore, in this embodiment, the side surface 2AA2 (2AB2) is disposed as the second surface 22 so as to directly face the skirt guard 5B.

[0055] That is, in this embodiment, The demarcation (side end demarcation) 2A is composed of laminated structures 2AA, 2AB formed by laminating materials, and has a first surface 21 (2AA1, 2AB1, 2AA3, 2AB3) along the lamination direction L of the materials, and a second surface 22 (2AA2, 2AB2) having a smaller coefficient of friction than the first surface 21, The demarcation 2A is arranged so that the second surface 22 is the surface facing the skirt guard 5B.

[0056] Other configurations are the same as in Example 1. In this example, the second surface having the function of the sliding member 2AC is integrally formed with the side end demarcation 2A, which reduces the number of parts and shortens the work time required to assemble the side end demarcation 2A.

[0057] Some of the features of the above-described embodiment are listed below. (1) A passenger conveyor 100 including steps 2 that are endlessly connected and move in a circular motion, a balustrade 3 arranged on the side of the steps 2, a skirt guard 5B arranged at the bottom of the balustrade 3, and a demarcation 2A provided at the top end of the steps 2, The demarcation 2A is composed of a laminated structure 2AA (2AB) in which materials are laminated, and has a first surface 21 along the lamination direction L of the materials and a second surface 22 having a smaller friction coefficient than the first surface 21, The demarcation 2A is arranged so that the second surface 22 is the opposing surface facing the skirt guard 15B.

[0058] (2) In (1), The demarcation 2A is made by laminating materials in a direction L perpendicular to the tread surface of the step 2. The second surface 22 is made of a separate member that has a smaller coefficient of friction than the first surface 21 and is different from the laminated structure 2AA (2AB).

[0059] (3)(1) The demarcation 2A is made by laminating materials in a direction L parallel to the width direction of the step 2. The second surface 22 is formed by an end surface in the lamination direction L of the laminated materials.
