Detailed Description

Embodiment 1.

Fig. 1 is a configuration diagram showing an escalator device including a moving handrail according to embodiment 1 of the present invention. The moving handrail 1A is formed in a ring shape. The moving handrail 1A is driven by a driving member such as a pulley or a roller to move circularly. The moving handrail 1A is rotated at the lower floor entrance 2 and the upper floor entrance 3 of the escalator device by the circulating movement of the moving handrail 1A.

Fig. 2 is a sectional view showing the moving handrail 1A of fig. 1 and a handrail guide to which the moving handrail 1A is mounted. Fig. 2 shows a cross section perpendicular to the longitudinal direction of the moving handrail 1A. The moving handrail 1A includes a handrail main body 101, a tension body 102, and a cloth 103.

The armrest body 101 is formed in a C-shaped cross section. The armrest main body 101 is formed in a ring shape. The direction along the armrest body 101 is the armrest longitudinal direction. The handrail longitudinal direction is the same as the longitudinal direction of the moving handrail 1A. The outer peripheral surface of the armrest body 101 is an exterior surface 104. The inner peripheral surface of the armrest body 101 is a guide surface 105. The guide surface 105 is a surface of the handrail main body 101 facing the handrail guide 4. The exterior surface 104 is a surface of the escalator device to be touched by a user's hand. The cloth 103 is disposed on the guide surface 105. The guide surface 105 moves along the handrail guide 4. The handrail main body portion 101 is attached to the handrail guide 4 such that the handrail main body portion 101 covers the surface of the handrail guide 4. The armrest body 101 has a flat plate portion facing the armrest rail 4 in the height direction and a pair of ear portions sandwiching the armrest rail 4 in the width direction of the moving armrest 1A.

As a material constituting the armrest body portion 101, a thermoplastic elastomer of a monomer such as polyurethane, polystyrene, or polyolefin can be cited. The material constituting the armrest body 101 may be a thermoplastic elastomer obtained by mixing two or more kinds of thermoplastic elastomers, such as polyurethanes, polystyrenes, and polyolefins, which are single monomers.

The tensile member 102 is embedded in the armrest body 101. The tension member 102 is disposed to extend in the longitudinal direction of the handrail. Thereby, the tensile strength and the bending strength of the moving handrail 1A satisfy the required strength. Examples of the material constituting the tension body 102 include a metal plate and a plurality of steel cables.

Examples of the material constituting the cloth 103 include fibers such as cotton and hemp. Further, as a material constituting the cloth 103, a resin such as polyester can be cited. This reduces the friction coefficient of the surface of the cloth 103. Cloth 103 is attached to guide surface 105 in such a manner that cloth 103 covers guide surface 105. The cloth 103 attached to the guide surface 105 moves relative to the surface of the handrail guide 4 by the moving handrail 1A circulating.

The moving handrail 1A is manufactured by joining one end portion in the longitudinal direction and the other end portion in the longitudinal direction of 1 moving handrail long member to each other. Next, the joint portion of the moving handrail 1A will be described. Fig. 3 is a bottom view showing the moving armrest 1A of fig. 2. Fig. 4 is a sectional view taken along line IV-IV of fig. 3. Fig. 5 is a sectional view taken along line V-V of fig. 3. The joint of the moving handrail 1A includes a joint of the handrail main body 101, a joint of the tension body 102, and a joint of the cloth 103. The joint of the armrest body 101 is P1, the joint of the cloth 103 is P2, and the joint of the tension body 102 is P3.

In the joint P1, the joint surface 106 of the armrest main body 101 disposed at the one longitudinal end 501 of the elongated member for moving armrest 5 and the joint surface 107 of the armrest main body 101 disposed at the other longitudinal end 502 of the elongated member for moving armrest 5 are joined to each other. The engaging surface 106 and the engaging surface 107 contact each other.

The cloth 103 has a lapped portion 108 disposed at the other end 502 in the longitudinal direction of the elongated member for moving handrail 5 and a lapping portion 109 disposed at one end 501 in the longitudinal direction of the elongated member for moving handrail 5. The overlapping portion 109 overlaps the surface of the overlapped portion 108 on the handrail guide 4 side. The lap portion 109 and the lap-receiving portion 108 are bonded to each other via an adhesive. A region where the lap portion 109 and the lapped portion 108 overlap each other in the cloth 103 is defined as a lap region 110.

In the joint portion of the moving handrail 1A according to embodiment 1, the rigidity ratio of the non-joint portion and the joint portion of the moving handrail 1A is closer to 1 than the joint portion of the conventional moving handrail shown in patent document 2. As a result, when the moving handrail 1A is caused to travel, the contact between the moving handrail 1A and the members constituting the escalator becomes smooth, and there is an effect that damage of the surface resin on the appearance side due to the rigidity ratio between the non-joint portion and the joint portion of the moving handrail 1A can be suppressed.

The position of the end of the overlapping portion 109 in the armrest longitudinal direction is the position of the joint portion P2 in the armrest longitudinal direction. On the surface of the cloth 103 facing the handrail guide 4, a boundary portion 111 is formed in which the end portion of the cloth 103 in the handrail longitudinal direction is disposed. In other words, the end of the cloth 103 in the handrail longitudinal direction is disposed on the surface of the cloth 103 facing the handrail guide 4. The boundary portion 111 indicates a gap formed between the end portion of the cloth 103 and the starting point of the overlapped portion 108 of the cloth constituting the overlapped portion 108. The boundary portion 111 is a space in which a part of the resin sheet 112 is filled by a hot-pressing process. The boundary portion 111 is an intermediate product formed before the hot pressing step. Therefore, the end of the lap portion 109 in the armrest longitudinal direction is disposed at the boundary portion 111. In other words, the end of the cloth 103 in the handrail longitudinal direction is the end of the lap portion 109 in the handrail longitudinal direction. The position of the end of the overlapped portion 108 in the armrest longitudinal direction is the position of the joint portion P1 in the armrest longitudinal direction.

The cloth 103 is made of a nonwoven fabric or a woven fabric. The woven fabric is formed by plain or silk weaving a twisted yarn or a single yarn. Therefore, in the cut surface of the cloth 103, the end of the cloth or the yarn is exposed regardless of the cutting method. In a state where the end of the cloth 103 is exposed, the moving handrail 1A is circularly moved, and the end of the cloth 103 is brought into contact with a driving member that circularly moves the moving handrail 1A. This causes the end of the cloth 103 to burst. When the fraying occurs, the fraying portion of the cloth 103 becomes a starting point from which the lapping portion 109 is peeled off from the lapped portion 108. The lap portion 109 peels off the overlapped portion 108, which deteriorates the moving handrail 1A.

Therefore, in embodiment 1, the moving handrail 1A further includes the resin sheet 112. The resin sheet 112 is provided on the cloth 103 so that the cloth 103 is interposed between the resin sheet 112 and the handrail main body portion 101. The resin sheet 112 covers the boundary portion 111. This prevents the end of the cloth 103 from coming into contact with the driving member that circulates the moving handrail 1A.

A recessed step portion 113 is formed at the end of the tension body 102 disposed at one end 501 in the longitudinal direction. The stepped portion 113 has a concave shape when viewed perpendicularly to the tension body 102. A step portion 114 is formed in a convex shape at an end portion of the tension body 102 disposed at the other end portion 502 in the longitudinal direction. The stepped portion 114 is convex when viewed perpendicularly to the tension body 102. In the engaging portion P3, the step portion 113 and the step portion 114 are engaged with each other in a state where the step portion 113 and the step portion 114 are fitted to each other.

Next, the shape of the resin sheet 112 will be described. The shape of the resin sheet 112 described here is an example, and other shapes may be used. The position of one end of the resin sheet 112 in the longitudinal direction of the handrail is P2A, and the position of the other end of the resin sheet 112 in the longitudinal direction of the handrail is P2B. A joint P2 is disposed at the center between the position P2A and the position P2B in the armrest longitudinal direction. The dimension between the position P2A and the position P2B in the longitudinal direction of the armrest is 1mm to 100 mm. In addition, the positions of the position P2A and the position P2B may be the positions where the joint P2 is disposed between the position P2A and the position P2B in the armrest longitudinal direction, and the joint P2 may not be disposed at the center between the position P2A and the position P2B in the armrest longitudinal direction.

One end portion and the other end portion of the resin sheet 112 in the handrail longitudinal direction are formed to linearly extend in the width direction of the moving handrail 1A. Further, the one end portion and the other end portion of the resin sheet 112 in the handrail longitudinal direction may not extend linearly in the width direction of the moving handrail 1A.

The midpoint of the joining portion P2 in the width direction of the moving handrail 1A is Z. The midpoint Z is the point that the resin sheet 112 should minimally cover. The dimension between the midpoint Z in the width direction of the moving handrail 1A and each of the two ends of the resin sheet 112 is preferably 1mm or more and not more than the dimension from the midpoint Z to each of the pair of inflection points of the handrail main body portion 101 having the C-shaped cross section. Depending on the shape of the moving handrail 1A, for example, the dimension between the midpoint Z in the width direction of the moving handrail 1A and each of the both ends of the resin sheet 112 is preferably in the range of 10mm to 35 mm. The dimension of the resin sheet 112 in the thickness direction is preferably 0.1mm to 10mm, and more preferably 0.2mm to 2 mm. The dimension of the resin sheet 112 in the thickness direction is smaller than the dimension between the cloth 103 and the handrail guide 4. The cloth 103 and the handrail guide 4 are in contact with each other at a portion of the moving handrail 1A having a large curvature and formed in a C-shaped cross section. On the other hand, a gap is formed between the cloth 103 and the handrail guide 4 in a portion near the center in the width direction of the conveyance surface of the moving handrail 1A. When the moving handrail 1A moves while the cloth 103 in the vicinity of the center in the width direction of the conveyance surface of the moving handrail 1A is constantly in contact with the handrail guide 4, the sliding performance of the moving handrail 1A with respect to the handrail guide 4 is reduced, and abrasion occurs between the cloth 103 and the handrail guide 4. Therefore, the dimension of the resin sheet 112 in the thickness direction needs to be smaller than the dimension between the cloth 103 and the handrail guide 4. The dimension between the cloth 103 and the handrail guide 4 in this case is a dimension between the cloth 103 and the handrail guide 4 in a portion near the center in the width direction of the conveyance surface of the moving handrail 1A.

The resin sheet 112 is made of the same material as the material of the handrail main body portion 101. The material of the resin sheet 112 may be different from the material of the handrail main body portion 101. Examples of the material constituting the resin sheet 112 include thermoplastic elastomers of monomers such as polyurethanes, polystyrenes, and polyolefins. The material constituting the resin sheet 112 may be a thermoplastic elastomer obtained by mixing two or more kinds of thermoplastic elastomers of monomers such as polyurethanes, polystyrenes, and polyolefins.

Next, a method for manufacturing the moving handrail 1A will be described. Fig. 6 is a flowchart illustrating a method of manufacturing the moving handrail 1A of fig. 1. First, in step S1, an extrusion molding process is performed. In the extrusion molding step, the elongated member 5 for the moving handrail is formed. In the extrusion molding step, first, the tension member 102 and the cloth 103 are disposed on an insert line of an extrusion molding machine, not shown. The tensile member 102 is disposed at a position embedded in the thermoplastic elastomer. The cloth 103 is disposed at a position where the guide surface 105 is formed.

Then, the thermoplastic elastomer is put into a die of an extrusion molding machine, and the grip body 101 is extrusion molded together with the tensile member 102 and the cloth 103.

Then, the continuously molded elongated member for a traveling armrest 5 is cooled by a refrigerant such as water or air, and then wound around a primary storage core.

Thereafter, in step S2, a cutting step is performed. In the cutting step, the elongated member 5 for the moving handrail wound around the primary storage core is cut to a length suitable for use as a final product. The cut-off section of the elongated member for a handrail 5 is the same as the section of the handrail 1A shown in fig. 2. The extrusion molding step is an example, and the extrusion molding step may be performed by another method.

Fig. 7 is a plan view showing the elongated member for a traveling armrest 5 formed in the extrusion molding process of fig. 6. In step S2, the elongated member for moving handrail 5 is cut to a length suitable for use of the escalator device. The position of one end of the elongated member 5 for moving the handrail in the longitudinal direction of the handrail is Ca, and the position of the other end thereof is Cb. In this example, a description will be given of a configuration in which both end portions of the elongated member 5 for a moving handrail are cut in the handrail longitudinal direction, but when one of both end portions of the elongated member 5 for a moving handrail is already cut in the handrail longitudinal direction, only the other end portion is cut in the cutting step.

Thereafter, in step S3, a cut end portion processing step is performed. In the cut end portion processing step, one longitudinal end portion 501 of the elongated member for traveling handrail 5 is formed, and the other longitudinal end portion 502 of the elongated member for traveling handrail 5 is formed. The order of forming the one longitudinal end portion 501 and the other longitudinal end portion 502 may be either the order of forming the one longitudinal end portion 501 and then forming the other longitudinal end portion 502, or the order of forming the other longitudinal end portion 502 and then forming the one longitudinal end portion 501. Further, the longitudinal one end portion 501 and the longitudinal other end portion 502 may be formed at the same time in the order of forming the longitudinal one end portion 501 and the longitudinal other end portion 502.

In the molding of the one longitudinal end portion 501, the portion of the handrail main body portion 101 and the portion of the cloth 103 are cut off at the distal end portion d1 of the one longitudinal end portion 501 by a heating device, a cutting device, or the like. Fig. 8 is a plan view showing the elongated member for a walking armrest 5 in which the tension body 102 is exposed at one longitudinal end 501 and the other longitudinal end 502 in fig. 7. The tensile member 102 at the distal end portion d1 is exposed by cutting away a portion of the handrail main body portion 101 and a portion of the cloth 103 at the one end portion 501 in the longitudinal direction.

Then, at the base end portion d2 of the one end portion 501 in the longitudinal direction, the portion of the armrest body 101 disposed on the front side of the elongated member for moving armrest 5 is cut off. Here, the front side refers to the appearance surface 104 side of the moving handrail 1A. Thereby, the front side of the tension body 102 at the base end portion d2 is exposed.

Then, at the base end portion d2 of the one end portion 501 in the longitudinal direction, the portion of the handrail main body portion 101 between the tension body 102 and the cloth 103 is cut off. Thereby, the lap portion 109 is formed.

Thereafter, the portion of the armrest body 101 at the base end portion d2 of the one longitudinal end 501 is cut away to form the joint surface 106. Thereafter, a concave step portion 113 is formed in the tension body 102 at one end portion 501 in the longitudinal direction. Fig. 9 is a plan view showing the elongated member for walking armrest 5 in which the tension body 102 is formed at one longitudinal end 501 and the other longitudinal end 502 in fig. 8. Fig. 10 is a perspective view of one end portion 501 in the longitudinal direction in fig. 9 viewed from the back side.

In forming the longitudinal direction other end portion 502, as shown in fig. 8, the armrest body portion 101 disposed on the front side of the longitudinal direction other end portion 502 is removed. Thereby, the front side of the tension body 102 at the other end portion 502 in the longitudinal direction is exposed.

Thereafter, as shown in fig. 9, a convex step portion 114 is formed in the tensile member 102 at the other end portion 502 in the longitudinal direction. The stepped portions 113 and 114 are shaped to fit each other.

Thereafter, the cloth 103 at the other end portion 502 in the longitudinal direction is pressed against the tension body 102 by the pressing device, and a concave portion is formed in the cloth 103. Thereby, the lapped portion 108 is formed. The size of the concave portion of the cloth 103 in the thickness direction is obtained by adding the size of the lap portion 109 in the thickness direction to the size of the adhesive for joining the lap portion 109 and the lapped portion 108 to each other in the thickness direction.

Thereafter, the joint surface 107 is formed on the armrest body 101 at the other end portion 502 in the longitudinal direction. Fig. 11 is a perspective view of the other end portion 502 in the longitudinal direction of fig. 9 viewed from the back side.

The description has been given of the configuration in which the shape of each of the joint surfaces 106 and 107 is a plane along a plane perpendicular to the longitudinal direction of the handrail, but the configuration is not limited thereto. The shape of each of the joint surfaces 106 and 107 may be a plane inclined with respect to a plane perpendicular to the longitudinal direction of the handrail, for example. The shapes of the bonding surface 106 and the bonding surface 107 may be irregular shapes that fit into each other.

Fig. 12 is a plan view showing one longitudinal end portion 501 and the other longitudinal end portion 502 joined to each other after the cut end portion processing step of fig. 6. Fig. 13 is a cross-sectional view taken along line XIII-XIII in fig. 12. Fig. 14 is a plan view showing a state in which one longitudinal end portion 501 and the other longitudinal end portion 502 of fig. 12 are in contact with each other. Then, the handrail-moving elongated member 5 is bent so that the one longitudinal end portion 501 and the other longitudinal end portion 502 face each other in the handrail longitudinal direction, and the joint surface 106 and the joint surface 107 contact each other. In this example, the one longitudinal end portion 501 moves toward the other longitudinal end portion 502, but the present invention is not limited thereto, and the other longitudinal end portion 502 may move toward the one longitudinal end portion 501. Further, the longitudinal one end portion 501 and the longitudinal other end portion 502 may be moved in a direction to approach each other.

Thereafter, the lap portion 109 is overlapped on the lap portion 108, and the lap portion 108 and the lap portion 109 are bonded to each other. Thereafter, the step portion 113 and the step portion 114 are fitted to each other.

In this example, a description is given of a configuration in which the joint surface 106 and the joint surface 107 are brought into contact with each other, then the lap portion 109 is overlapped on the lap portion 108, and then the step portion 113 and the step portion 114 are fitted to each other. However, these orders may be changed as needed. The adhesive for bonding the to-be-bonded portion 108 and the bonding portion 109 to each other may be applied before the one longitudinal end portion 501 and the other longitudinal end portion 502 face each other, or after the bonding surface 106 and the bonding surface 107 contact each other.

Thereafter, as shown in fig. 6, in step S4, a resin sheet setting step is performed. Fig. 15 is a cross-sectional view showing a state in which the resin sheet 112 is provided to the elongated member for a traveling armrest 5 in fig. 14. First, the resin sheet 112 is provided on the cloth 103 so that the cloth 103 is sandwiched between the handrail main body portion 101 and the resin sheet 112. Thereby, the end of the bridging portion 109 is covered with the resin sheet 112. In other words, the boundary portion 111 is covered with the resin sheet 112.

As a method of attaching the resin sheet 112 to the cloth 103, for example, a method of attaching the resin sheet 112 to the cloth 103 in a state where the resin sheet 112 is heated in advance and the resin sheet 112 is sufficiently softened can be cited. Further, as a method of attaching the resin sheet 112 to the cloth 103, the following method can be mentioned: in a state where the resin sheet 112 is placed on the cloth, the resin sheet 112 is heated by a heating device, the resin sheet 112 is sufficiently softened, and the resin sheet 112 is attached to the cloth 103. The method of attaching the resin sheet 112 to the cloth 103 is not limited to this, as long as the resin sheet 112 is not easily peeled off from the cloth 103.

Thereafter, as shown in fig. 6, in step S5, a resin replenishing step is performed. As shown in fig. 15, the supplemental resin 6 is added to the region where the portion of the armrest body 101 on the front side of each of the joint P1 of the armrest body 101, the joint P2 of the cloth 103, and the joint P3 of the tensile member 102 has been cut away. The supplemental resin 6 is made of the same material as the armrest main body portion 101.

Fig. 16 is a side view showing a state in which the supplementary resin 6 of fig. 15 and the elongated member for a traveling armrest 5 on which the supplementary resin 6 is placed are pressurized and heated. Thereafter, as shown in fig. 6, in step S6, a hot pressing step is performed. In the hot pressing step, the supplementary resin 6 and the elongated member for a traveling armrest 5 on which the supplementary resin 6 is placed are pressurized and heated by the hot pressing device 7. The hot press device 7 covers the supplementary resin 6 and the part of the elongated member for a traveling armrest 5 on which the supplementary resin 6 is placed. The hot press device 7 covers the periphery of the portion of the elongated member for a traveling armrest 5 on which the supplemental resin 6 is placed.

Further, the one longitudinal end portion 501 and the other longitudinal end portion 502 are pressed in the direction of approaching each other by the clamper 8. The pressing and heating by the hot press 7 are performed in a state where the pressing by the clamper 8 is performed. After the start of the pressurization and heating by the hot press 7, the pressurization by the clamper 8 is released. Further, depending on the specification of the hot press apparatus 7, the clamper 8 may not be necessary. Fig. 17 is a cross-sectional view showing one longitudinal end 501 and the other longitudinal end 502 of the moving handrail 1A after the hot-pressing step. In the hot pressing step, one longitudinal end portion 501 and the other longitudinal end portion 502 of the 1 long members 5 for moving handrail are joined to each other. In the resin sheet setting step, a gap is formed in the boundary portion 111 between the cloth 103 and the resin sheet 112, and in the heat pressing step, a part of the resin sheet 112 is embedded. Therefore, the gap of the boundary portion 111 disappears by the hot pressing process. According to the above processing, the manufacture of the moving handrail 1A is completed. The timing of attaching the resin sheet 112 to the cloth 103 may be any timing before or after the pressing and heating by the hot press 7. Further, the resin sheet 112 may be attached to the cloth 103 by applying pressure and heat by the heat press 7.

As described above, according to the moving handrail 1A according to embodiment 1 of the present invention, the boundary portion 111 where the end portion of the cloth 103 in the handrail longitudinal direction is disposed is formed on the surface of the cloth 103 facing the handrail guide 4. The boundary portion 111 is covered with a resin sheet 112. This prevents the end of the cloth 103 from being exposed in the longitudinal direction of the handrail. Therefore, the driving member that drives the moving handrail 1A can be prevented from abutting against the end of the cloth 103. As a result, the life of the moving handrail 1A can be extended. In addition, by preventing the end of the cloth 103 from abutting against the driving member, the generation of abnormal noise can be suppressed. In addition, by preventing the end of the cloth 103 from abutting against the driving member, the end of the cloth 103 can be prevented from being peeled off from the handrail main body portion 101. As a result, the occurrence of abnormal stop of the escalator device due to peeling of the cloth 103 can be suppressed.

In addition, the end portion of the lap portion 109 in the armrest longitudinal direction is disposed at the boundary portion 111. This prevents the lap joint 109 from being peeled off from the lapped section 108.

The dimension of the resin sheet 112 in the thickness direction is smaller than the dimension of the gap between the cloth 103 and the handrail guide 4. This reduces the frictional force generated between the resin sheet 112 and the handrail guide 4.

The resin constituting the resin sheet 112 is the same as the resin constituting the armrest main body portion 101. This facilitates the formation of the resin sheet 112.

In the method for manufacturing the moving handrail according to embodiment 1 of the present invention, the boundary portion 111 is covered with the resin sheet 112 in the resin sheet providing step. This prevents the end of the cloth 103 from being exposed in the longitudinal direction of the handrail. Therefore, the driving member that drives the moving handrail 1A can be prevented from abutting against the end of the cloth 103. As a result, the life of the moving handrail 1A can be extended.

In the resin sheet setting step, after the resin sheet 112 is heated to soften the resin sheet 112, the resin sheet 112 is attached to the cloth 103 so that the boundary portion 111 is covered with the resin sheet 112. This makes it easy to attach the resin sheet 112 to the cloth 103.

In the resin sheet setting step, after the boundary portion 111 is covered with the resin sheet 112, the resin sheet 112 is heated to soften the resin sheet 112, and the resin sheet 112 is attached to the cloth 103. This makes it easy to attach the resin sheet 112 to the cloth 103.

Embodiment 2.

Fig. 18 is a perspective view showing one end in the longitudinal direction of an elongated member for a moving handrail constituting a moving handrail according to embodiment 2 of the present invention. In the moving handrail 1B, the shape of the overlapping portion 109 at the one end portion 501 in the longitudinal direction of the long member 5 for moving handrail is different from that of the moving handrail 1A of embodiment 1. An inclined portion 115 is formed at the end portion of the lap portion 109. The inclined portion 115 is formed to be inclined with respect to a surface extending in the thickness direction of the moving handrail 1B when viewed in the width direction of the moving handrail 1B. Specifically, the inclined portion 115 is formed such that a front side portion of the inclined portion 115 extends from the armrest main body portion 101 toward the distal end side in the longitudinal direction more than a rear side portion of the inclined portion 115. The other structures are the same as those in embodiment 1.

As described above, according to the moving handrail 1B according to embodiment 2 of the present invention, the life of the moving handrail 1B can be extended as in the moving handrail 1A according to embodiment 1.

In embodiment 2, a configuration in which the inclined portion 115 is formed so that the front side portion of the inclined portion 115 extends from the armrest main body portion 101 toward the longitudinal end side rather than the rear side portion of the inclined portion 115 has been described. However, as shown in fig. 19, the inclined portion 116 may be formed such that a portion on the back side of the inclined portion 116 extends from the armrest main body portion 101 toward the longitudinal end side than a portion on the front side of the inclined portion 116.

The shape of the lap portion 109 may be a wave shape, a concave-convex shape, a semicircular shape, or the like as long as the life of the moving handrail 1B is not reduced and the function of the moving handrail 1B is not insufficient.

Embodiment 3.

Fig. 20 is a sectional view showing a moving handrail according to embodiment 3 of the present invention. Fig. 21 is a perspective view illustrating a procedure of manufacturing the moving handrail of fig. 20. Fig. 22 is a perspective view showing a state in which the covering resin 117 of fig. 21 is placed on the elongated member for moving handrail 5. In the moving handrail 1C, the covering resin 117 is removed from the portion of the long member 5 for moving handrail on the back side of the handrail main body portion 101. The overlapped portion 108 is included in the region where the covering resin 117 is removed from the elongated member for moving handrail 5. Thereafter, the one longitudinal end portion 501 and the other longitudinal end portion 502 are joined to each other. In the armrest longitudinal direction, the joint portions P4, P5 of the covering resin 117, the joint portion P1 of the armrest body 101, the joint portion P2 of the cloth 103, and the joint portion P3 of the tension body 102 are arranged to be offset from each other.

Thereafter, as shown in fig. 22, the covering resin 117 is placed in the area where the covering resin 117 is removed in the elongated member for a walking armrest 5. The other configurations are the same as those in embodiment 1 or embodiment 2.

As described above, according to the moving handrail 1C according to embodiment 3 of the present invention, the life of the moving handrail 1C can be extended as in embodiments 1 and 2. In the armrest longitudinal direction, the joint portions P4 and P5 of the covering resin 117, the joint portion P1 of the armrest body 101, the joint portion P2 of the cloth 103, and the joint portion P3 of the tension body 102 are arranged to be offset from each other. This prevents bending stress from simultaneously acting on the joint of the cover resin 117, the joint P1 of the armrest body 101, the joint P2 of the cloth 103, and the joint P3 of the tension body 102.

Embodiment 4.

Fig. 23 is a perspective view showing a moving armrest according to embodiment 4 of the present invention. As shown in fig. 21, in the moving handrail 1C according to embodiment 3, the end surface of the coating resin 117 in the handrail longitudinal direction is parallel to the cross-sectional surface of the long member 5 for a moving handrail. In other words, the end surface of the coating resin 117 in the handrail longitudinal direction is a surface perpendicular to the handrail longitudinal direction. As shown in fig. 22, in embodiment 3, in the hot-pressing step, the joint P4 and the joint P5 between the end face of the covering resin 117 and the region of the elongated member for moving handrail 5 from which the covering resin 117 is removed are melted together.

On the other hand, in the moving handrail 1D according to embodiment 4, the end surface 118 of the covering resin 117 in the handrail longitudinal direction is inclined with respect to the cross-sectional surface of the long member 5 for a moving handrail. In other words, the end surface 118 of the coating resin 117 in the handrail longitudinal direction is inclined with respect to a plane perpendicular to the handrail longitudinal direction. After the covering resin 117 with the inclined end face 118 is provided to the region of the elongated member for a traveling armrest 5 from which the covering resin 117 is removed, they are mutually melted in the hot-pressing step. This enlarges the area of fusion between the coating resin 117 and the region of the elongated member for moving handrail 5 from which the coating resin 117 is removed. The other configurations are the same as those in embodiments 1 to 3.

As described above, according to the moving handrail 1D of embodiment 4, the end surface 118 of the coating resin 117 in the handrail longitudinal direction is inclined with respect to the plane perpendicular to the handrail longitudinal direction. Thus, the area of fusion between the coating resin 117 and the region of the elongated member for moving handrail 5 from which the coating resin 117 is removed can be increased as compared with the case where the end face of the coating resin 117 in the handrail longitudinal direction is a plane perpendicular to the handrail longitudinal direction. By increasing the melting area of the resins, the peeling and crack generation of the joint P4 and the joint P5 can be suppressed, and the peeling and crack generation timing of the joint P4 and the joint P5 can be delayed. As a result, the effect of extending the product life of the moving handrail 1D can be obtained. The cross-sectional shape of the end surface 118 of the coating resin 117 is not limited to a shape inclined with respect to a plane perpendicular to the handrail longitudinal direction, and may be a shape in which the melting area of the resins is enlarged, for example, a shape such as an uneven shape.

Embodiment 5.

Fig. 24 is a perspective view showing a moving armrest according to embodiment 5 of the present invention. As shown in fig. 22, in the moving handrail 1C according to embodiment 3, in the hot-pressing step, the joint P4 and the joint P5 between the end face of the covering resin 117 and the region of the elongated member 5 for a moving handrail from which the covering resin 117 is removed are melted together.

On the other hand, in the moving handrail 1E according to embodiment 5, the adhesive resin 119 is disposed between the cover resin 117 and the cloth 103. Fig. 24 shows a moving handrail 1E for performing a resin replenishing process. In the resin replenishing step, the bonding resin 119 is sandwiched between the cover resin 117 and the cloth 103. In the hot pressing step performed after the resin replenishing step, the covering resin 117 and the cloth 103 are bonded to each other. When the cover resin 117 and the cloth 103 are bonded to each other, the bonding resin 119 is disposed between the cover resin 117 and the cloth 103, and thus the bonding strength between the cover resin 117 and the cloth 103 is improved. As a material constituting the bonding resin 119, the same resin as that constituting the moving handrail 1E or a resin having a similar molecular structure is preferable. Examples of the material constituting the adhesive resin 119 include thermoplastic elastomers of monomers such as polyurethanes, polystyrenes, and polyolefins. Examples of the material constituting the adhesive resin 119 include a thermoplastic elastomer obtained by mixing two or more kinds of monomeric thermoplastic elastomers such as polyurethanes, polystyrenes, and polyolefins. The other configurations are the same as those in embodiments 1 to 4.

As described above, according to the moving handrail 1E according to embodiment 5, the adhesive resin 119 is disposed between the cover resin 117 and the cloth 103. This improves the bonding strength between the cover resin 117 and the cloth 103, compared to the case where the bonding resin 119 is not disposed between the cover resin 117 and the cloth 103. By increasing the adhesive strength between the cover resin 117 and the cloth 103, the cover resin 117 can be prevented from peeling off from the cloth 103. This can provide an effect of extending the product life of the moving handrail 1E.

Embodiment 5 can be combined with embodiments 1 to 4, and has an effect of extending the product life of the moving handrail in any case.
