[Solution] The passenger conveyor 1 comprises an endless circular handrail belt 4a running along the periphery of the parapet section 4, an inlet 9 provided at the base of the parapet section 4 at the boarding and alighting section 1a where the handrail belt 4a enters the truss 2, and a floor plate 7 at the boarding and alighting section 1a, and a blocking body 8 erected from the floor plate 7 within the widthwise projection of the handrail belt 4a when viewed in a plane.

Description

[Technical field]

[0001] The present invention relates to a people conveyor. [Background technology]

[0002] The handrail belt of the passenger conveyor runs along the periphery of a pair of balustrades on both ends of the conveyor. At the boarding / alighting entrance, the handrail belt is reversed at the newel and passes through the inlet and enters the interior of the structure. In the area where the handrail belt of the inlet enters, if a foreign object is drawn in, An inlet switch is provided to stop the vehicle from running. However, luggage such as suitcases of passengers getting off the passenger conveyor, or luggage of passengers who mistakenly enter the passenger conveyor, can come into contact with the handrail belt and be pulled into the lower part of the handrail belt, activating the inlet switch and stopping the passenger conveyor. One of the reasons for this is thought to be that handrail belts are made of a material with high friction in order to improve grip.

[0003] To solve such problems, a passenger conveyor is known that has a blocking body extending from the inside of the balustrade to the outside of the balustrade below the handrail belt and in front of the inlet (for example, Patent Document 1). However, since conventional obstructions are provided on the inside of the handrail, there is a risk that, for example, a passenger without baggage may trip over the obstruction and fall when getting off the passenger conveyor. Also, a passenger conveyor is known in which a blocking body is provided under a canopy that protrudes from the top of the inlet toward the landing side, in front of the inlet switch and inside the handrail (for example, Patent Document 2). However, in this case, although it does not interfere with passengers' walking, the blocking body is located just before the inlet switch, and after the foreign object is drawn into the handrail belt, the blocking body removes the foreign object just before the inlet switch, which is not sufficient to prevent the foreign object from being drawn in.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0009] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] Hereinafter, one embodiment of the passenger conveyor will be described with reference to Figures 1 to 5. Note that the following embodiment is provided as an example to aid in understanding the configuration of the passenger conveyor, and is not intended to limit the configuration of the passenger conveyor.

[0011] As shown in Figure 1, a person conveyor 1 may include, for example, a structure 2 installed on a main body, a transport section 3 for transporting people (passengers), a pair of balustrade sections 4 (only one is shown in Figure 1) arranged to sandwich the transport section 3 in the first horizontal direction D1, a drive section 5 for driving the transport section 3 and the balustrade sections 4, and a control panel 6 for controlling the entire device.

[0012] In each figure, the first direction D1 is the first lateral direction (also called the "width direction") D1 which is parallel to the horizontal direction, the second direction D2 is the second lateral direction (also called the "front-rear direction") D2 which is parallel to the horizontal direction and perpendicular to the first lateral direction D1, and the third direction D3 is the vertical direction perpendicular to the first lateral direction D1 and the second lateral direction D2, that is, the up-down direction D3. Also, when the passenger conveyor 1 is viewed in a plan view, at each boarding and disembarking section 1a, the direction away from the passenger conveyor 1 is the front, and the direction approaching the passenger conveyor 1 is the rear.

[0013] The passenger conveyor 1 according to this embodiment is an escalator with a stepped tread surface for transporting passengers, but is not limited to such a configuration. For example, the passenger conveyor 1 may be a moving walkway with a flat tread surface for transporting passengers.

[0014] The transport unit 3 may include, for example, as in this embodiment, an endless annular running unit 3a that rotates and runs when driven by the drive unit 5, and a plurality of steps 3b that are connected to the running unit 3a and run together with the running unit 3a, and have tread surfaces on which people can stand. Although not particularly limited, the running unit 3a may be, for example, a roller chain.

[0015] Also, for example, the running portions 3a may be provided as a pair separated from each other in the first horizontal direction D1, and the steps 3b may be disposed between the pair of running portions 3a, 3a. The steps 3b may be connected to the respective running portions 3a so as to be rotatable about the first horizontal direction D1.

[0016] The driving unit 5 may include, for example, as in this embodiment, a pair of rotating units 5a, 5a around which the running unit 3a is wound so that the step 3b is reversed and which rotate about an axis in the first horizontal direction D1, and a driving source 5b that rotates the rotating unit 5a. Although not particularly limited, the rotating unit 5a may be, for example, a sprocket, and the driving source 5b may be, for example, a motor.

[0017] The balustrade section 4 may include, for example, an endless circular handrail belt 4a that rotates and runs, a balustrade main body section 4b that supports the handrail belt 4a, and a cover section 4c that covers the lower part of the balustrade main body section 4b. For example, the handrail belt 4a runs by being driven by the drive section 5, and the running of the handrail belt 4a may be synchronized with the running of the step 3b.

[0018] In this embodiment, a pair of balustrades 4 (handrail belts 4a) are provided to sandwich the step 3b in the first horizontal direction D1, so the balustrades 4 (handrail belts 4a) are positioned outside the step 3b in the first horizontal direction D1. Note that the outside in the first horizontal direction D1 refers to the side farther from the center line (virtual line) of the passenger conveyor 1 in the first horizontal direction D1, and the inside in the first horizontal direction D1 refers to the side closer to the center line of the passenger conveyor 1 in the first horizontal direction D1.

[0019] The structure 2 may include machine rooms 2a, 2a arranged at each end in the second horizontal direction D2, as in this embodiment. Although not particularly limited, the structure 2 may have a truss structure or a girder structure composed of a plurality of frame members. The machine room 2a may house the rotating unit 5a and the driving source 5b therein, as in this embodiment.

[0020] 1 to 3, the passenger conveyor 1 may include a floor plate 7 attached to the structure 2 so as to cover the machine rooms 2a, 2a from above. As a result, the floor plate 7 constitutes the floor of the boarding and disembarking section 1a disposed at each end of the transport section 3 in the second lateral direction D2 for boarding and disembarking the step 3b. Note that the floor of the boarding and disembarking section 1a may be constituted by the floor plate 7 and a building floor, for example, as in this embodiment.

[0021] The floor plate 7 is, for example, detachable from the structure 2, and may be arranged in a divided manner as in this embodiment. The number of divisions of the floor plate 7 is not particularly limited, but may be, for example, divided into three pieces as in this embodiment.

[0022] As shown in Figs. 2 to 5, a blocking body 8 may be provided in front of the inlet 9 between the floor plate 7 and the handrail belt 4a. Specifically, the blocking body 8 is provided in a manner that fits within at least the projection plane of the handrail belt 4a in the width direction in a plan view. In Fig. 3, the handrail belt 4a is hatched, and the handrail belt 4a and the blocking body 8 overlap in a plan view. For example, the blocking body 8 may be detachably attached to the floor plate 7, or may be fixed to the floor plate 7 by welding or the like.

[0023] As shown in Figs. 3 and 4, the blocking body 8 is provided at a position overlapping the handrail belt 4a with respect to the handrail belt front-rear end line L, which is virtually extended vertically downward from the front end of the handrail belt 4a. The blocking body 8 may be, for example, a quadrangular pyramid with four sides inclined from the floor plate 7 side, with the front-rear direction being the long side and the width direction being the short side, as shown in Fig. 5. In this embodiment, the blocking body 8 has a front inclined surface 8a inclined on the front side of the blocking body 8, a rear inclined surface 8b inclined on the rear side of the blocking body 8, and a pair of side inclined surfaces 8c, 8c inclined on both sides in the width direction of the blocking body 8. In this embodiment, the front inclined surface 8a and the rear inclined surface 8b have the same inclination angle, and the pair of side inclined surfaces 8c, 8c have the same inclination angle, but this is not limited to such a configuration. The front inclined surface 8a and the rear inclined surface 8b may have different inclination angles, and the pair of side inclined surfaces 8c, 8c may have different inclination angles. The inclination angle is, for example, 45 degrees.

[0024] In this embodiment, as shown in Fig. 4, the blocking body 8 is provided so that the lower end of the front inclined surface 8a coincides with the handrail belt front-rear end line L, but is not limited to such a configuration. For example, as shown in Fig. 6, the blocking body 8 may be provided so that the upper end of the front inclined surface 8a coincides with the handrail belt front-rear end line L.

[0025] Next, the action of the blocking body 8 to reduce the occurrence of baggage such as suitcases of passengers getting off the passenger conveyor 1 or baggage of passengers who mistakenly enter the passenger conveyor 1 coming into contact with the handrail belt 4a and being pulled under the handrail belt 4a will be described. For example, the wheel of a suitcase that has come into contact with the handrail belt 4a starts to be pulled under the front-rear end of the handrail belt 4a, and when the pulled-in wheel comes into contact with the front inclined surface 8a of the blocking body 8, the wheel is bounced forward and upward and detached from the handrail belt 4a. Even if the wheel is pulled in between the blocking body 8 and the handrail belt 4a, if there is a rear inclined surface 8b, the wheel will fall along the rear inclined surface 8b, and the wheel will not remain caught between the handrail belt 4a and the blocking body 8.

[0026] In addition, when the wheel of, for example, a suitcase, which has come into contact with the handrail belt 4a from the width direction D1, begins to be pulled below the handrail belt 4a from the width direction D1, when the pulled-in wheel comes into contact with the lateral inclined surface 8c of the blocking body 8, the wheel is bounced upward in the width direction and detaches from the handrail belt 4a.

[0027] [1] In view of the above, it is preferable that the passenger conveyor 1, as in this embodiment, is configured to include an endless circular handrail belt 4a running along the periphery of the parapet portion 4, an inlet 9 provided at the base of the parapet portion 4 at the boarding and alighting portion 1a where the handrail belt 4a enters the structure 2, and a floor plate 7 at the boarding and alighting portion 1a, with blocking bodies 8, 18, 28 erected from the floor plate 7 within the widthwise projection of the handrail belt 4a in a plan view.

[0028] With this configuration, the blocking body 8, which does not impede the walking of passengers, can reduce the amount of foreign objects being drawn toward the retraction opening of the handrail belt 4a without interfering with the walking of passengers getting off the passenger conveyor 1.

[0029] [2] In addition, it is preferable that the passenger conveyor 1 of [1] above be configured, as in this embodiment, such that the width of the blocking bodies 8, 18, 28 in the width direction D1 coincides with the width of the handrail belt 4a in the width direction D1 in a plan view.

[0030] According to such a configuration, foreign objects are less likely to enter below the handrail belt 4a in a plan view, so that it is possible to reduce foreign objects being drawn in toward the retraction opening of the handrail belt 4a.

[0031] [3] In addition, in the passenger conveyor 1 of the above [1] or [2], it is preferable that the blocking bodies 8, 18, 28 have at least a front inclined surface 8a, 18a, 28a at the front, as in this embodiment.

[0032] With this configuration, when a foreign object that is drawn in comes into contact with the forward inclined surfaces 8a, 18a, 28a of the blocking body 8, the foreign object is bounced upward and forward and detached from the handrail belt 4a, thereby reducing the amount of foreign object being drawn in toward the inlet of the handrail belt 4a.

[0033] [4] Furthermore, in the passenger conveyor 1 of [3] above, as in this embodiment, it is preferable that the blocking bodies 8, 18, 28 are configured such that the lower ends of the forward inclined surfaces 8a, 18a, 28a provided at the front in a plan view coincide with the front end portion of the handrail belt 4a.

[0034] This configuration reduces the amount of foreign objects being drawn in toward the retraction opening of the handrail belt 4a, and does not impede the walking of passengers getting on to the passenger conveyor 1 when the boarding / alighting direction is changed to the boarding / alighting opening 1a equipped with the blocking body 8, which becomes the boarding opening for passengers.

[0035] [5] In addition, in the passenger conveyor 1 of [3] above, as in this embodiment, it is preferable that the blocking bodies 8, 18, 28 are provided with widthwise inclined surfaces 8c, 18c, 28c at their widthwise ends.

[0036] With this configuration, foreign objects approaching from the width direction of the handrail belt 4a are bounced upward in the width direction and removed from the handrail belt 4a, thereby reducing the amount of foreign objects being drawn in toward the retraction opening of the handrail belt 4a.

[0037] The passenger conveyor 1 is not limited to the configuration of the embodiment described above, nor is it limited to the above-mentioned effects. Furthermore, the passenger conveyor 1 can be modified in various ways without departing from the spirit of the present invention. For example, it is possible to select one or more of the configurations and methods of the various modified examples described below and adopt them in the configurations and methods of the embodiment described above.

[0038] (A) In the passenger conveyor 1 according to the above embodiment, as in this embodiment, the blocking bodies 8, 18, 28 are configured such that the lower ends of the forward inclined surfaces 8a, 18a, 28a provided in the front in plan view coincide with the front end of the handrail belt 4a. However, the passenger conveyor 1 is not limited to such a configuration. For example, as shown in Fig. 6, the blocking bodies 8, 18, 28 may be configured such that the upper ends of the forward inclined surfaces 8a, 18a, 28a provided in the front in plan view coincide with the front end of the handrail belt 4a.

[0039] According to such a configuration, the foreign object removal action occurs before the foreign object approaches the handrail belt 4a, so that it is possible to reduce the foreign object being drawn toward the retraction opening of the handrail belt 4a at an early stage.

[0040] (B) In the passenger conveyor 1 according to the above embodiment, the blocking body 8 is configured to have a forward inclined surface 8a formed by a flat surface. However, the passenger conveyor 1 is not limited to such a configuration. For example, as shown in Fig. 7, the blocking bodies 18, 28 may be configured such that, instead of the forward inclined surface 8a, the forward inclined surfaces 18a, 28a are inverted R surfaces.

[0041] With this configuration, as a foreign object that comes into contact with the forward inclined surfaces 18a, 28a moves along the reverse R, the inclination angle becomes stronger, making it easier for the foreign object to be bounced upward and forward, further reducing the amount of foreign objects that are drawn toward the retraction port of the handrail belt 4a.

[0042] (C) In the passenger conveyor 1 according to the above embodiment, the blocking body 8 is configured to have a lateral inclined surface 8c formed by a flat surface. However, the passenger conveyor 1 is not limited to such a configuration. For example, as shown in Fig. 8, the width direction inclined surface 28c of the blocking body 28 may be configured to be formed in a concave shape (arcuate shape) in a plan view.

[0043] With this configuration, foreign matter drawn into the handrail belt 4a is guided away from the handrail belt 4a as it approaches the inlet 9, thereby further reducing the amount of foreign matter being drawn toward the inlet of the handrail belt 4a.

[0044] (D) For example, the order of execution of each process, such as operations, procedures, steps, and stages, in the methods and devices shown in the claims, specifications, and drawings, can be arbitrary, as long as the result of a previous process is not used in a subsequent process. For example, even if the description uses "first," "next," etc. for convenience, it does not mean that the processes must be executed in that order. [Explanation of symbols]
