Description

Technical Field

[0001] This specification relates to a man conveyor, parts for a man conveyor, and a method for manufacturing a man conveyor.

Background Art

[0002] Conventionally, for example, a man conveyor includes a structure having a horizontal frame extending in a first horizontal direction, a rail constituting a part of the man conveyor, and a holding unit for holding the rail. The holding unit includes a bracket for holding the rail, and bolts and nuts for fixing the bracket and the horizontal frame (for example, Patent Document 1). The bolts are inserted into respective through holes of the bracket and the horizontal frame, and the nuts are screwed onto the bolts.

[0003] By the way, it is difficult to form a through hole in the horizontal frame using a tool such as a drill, for example, in a state where the structure is installed on a housing. Therefore, there has been a demand for the ability to fix a holding unit for holding a conveyor component such as a rail to the horizontal frame regardless of the presence or absence of a through hole in the horizontal frame.

[0008] In each drawing, the dimensions of components may be enlarged or reduced from their actual dimensions for the sake of clarity, and the dimensional ratios between drawings may not be consistent. Furthermore, in each drawing, some components may be omitted for the sake of clarity.

[0009] Terms including ordinal numbers such as "1st," "2nd," etc., are used to describe various components, but these terms are used solely for the purpose of distinguishing one component from others, and the components are not particularly limited by these terms. Furthermore, the number of components including ordinal numbers is not particularly limited; for example, there may be only one. Also, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] The following description will explain one embodiment of a man conveyor and man conveyor components with reference to Figures 1 to 9. Note that the following embodiment is provided as an example to aid in understanding the configuration of the man conveyor and man conveyor components, and does not limit the configuration of the man conveyor and man conveyor components.

[0011] As shown in Figure 1, the man conveyor 1 may include, for example, a structure 2 installed on the building frame, a transport section 3 for transporting people (passengers), a pair of railing sections 4 (only one is shown in Figure 1) arranged to sandwich the transport section 3 in a first direction X1, and a drive section 5 for driving the transport section 3 and the railing sections 4.

[0012] In FIG. 1 (and FIG. 2), the first direction X1 is the first horizontal direction (also referred to as the "width direction") X1, the second direction X2 is the second horizontal direction (also referred to as the "front-rear direction") X2 that is orthogonal to the first horizontal direction X1, and the third direction X3 is the vertical direction X3 that is orthogonal to both the first horizontal direction X1 and the second horizontal direction X2. Note that the direction orthogonal to a specific direction refers to a direction parallel to the virtual plane orthogonal to the specific direction.

[0013] Further, the fourth direction X4 is the direction in which the conveying unit 3 conveys a person, and is an inclined direction X4 that is inclined and intersects with the second horizontal direction X2. The fifth direction X5 is a perpendicular direction X5 that is orthogonal to the inclined direction X4. Note that the direction that is inclined and intersects with a specific direction refers to a direction that is inclined and intersects with respect to the virtual plane orthogonal to the specific direction.

[0014] Also, the conveying directions X2 and X4 in which the conveying unit 3 conveys are the second horizontal direction X2 and the inclined direction X4. Note that the second to fifth directions X2 to X5 are directions parallel to the same virtual plane, and the first direction X1 is a direction orthogonal to the virtual plane.

[0015] The man conveyor 1 according to the present embodiment is an escalator with a stepped tread surface for conveying a person, but is not limited to such a configuration. For example, the man conveyor 1 may be a moving walkway (a moving path) with a flat tread surface for conveying a person.

[0016] The conveying unit 3 includes steps 3a on which a person rides and travels. Further, the conveying unit 3 may include, for example, an annular traveling unit 3b that rotates and travels as in the present embodiment. And, for example, as in the present embodiment, the traveling unit 3b rotates and travels by being driven by the driving unit 5, and the plurality of steps 3a are connected to the traveling unit 3b and travel together with the traveling unit 3b, which may be the configuration.

[0017] The drive unit 5 may, for example, as in this embodiment, include a drive wheel 5a around which the first end of the running unit 3b in the second horizontal direction X2 is wrapped and which rotates about the first horizontal direction X1 as an axis, a winding unit 5b that supports the second end of the running unit 3b in the second horizontal direction X2, a drive source 5c that rotates the drive wheel 5a, and a braking unit 5d that brakes the rotation of the drive wheel 5a. As a result, step 3a is reversed by the drive wheel 5a and also by the winding unit 5b.

[0018] The drive wheel 5a may be, for example, a sprocket. The winding portion 5b may be, for example, a guide material that guides the running portion 3b to reverse direction, or it may be, for example, a rotating material (e.g., a sprocket) around which the running portion 3b is wound and which rotates about a first horizontal direction X1 as an axis. The drive source 5c may be, for example, a motor and an inverter. The braking portion 5d may be, for example, a brake.

[0019] The railing section 4 may, for example, include a rotating, moving annular handrail belt 4a, a railing body section 4b that supports the handrail belt 4a, and a cover section 4c that covers the lower part of the railing body section 4b. For example, the handrail belt 4a may be driven by the drive unit 5, and the movement of the handrail belt 4a may be synchronized with the movement in step 3a.

[0020] As shown in Figure 2, for example, the traveling units 3b may be provided in pairs, separated in the first horizontal direction X1, and multiple steps 3a (only one is shown in Figure 2) may be arranged between the pair of traveling units 3b, 3b. Alternatively, for example, as in this embodiment, the transport unit 3 may be provided with a connecting shaft 3c that connects the pair of traveling units 3b, 3b, and the steps 3a may be rotatably connected to the connecting shaft 3c. In this configuration, the steps 3a are rotatably connected to each traveling unit 3b with the first horizontal direction X1 as the axis.

[0021] Step 3a may, for example, include a step body 3d and a first roller 3e connected to the step body 3d so as to be rotatable about a first horizontal direction X1 as an axis, as in this embodiment. Alternatively, the step body 3d may, for example, include a tread portion 3f on which a person steps, a curved kick portion 3g, and a pivot portion 3h rotatably connected to a connecting shaft 3c, as in this embodiment.

[0022] The running section 3b may, for example, include a chain 3i formed in an annular shape, and a second roller 3j and a third roller 3k connected to the chain 3i so as to be rotatable about a first horizontal direction X1 as an axis, as in this embodiment. For example, in this embodiment, the second roller 3j is rotatably connected to the end of the connecting shaft 3c, and the third roller 3k is positioned away from the connecting shaft 3c. As a result, the first roller 3e and the second roller 3j are connected to the step body 3d and support the load of the step body 3d.

[0023] As shown in Figure 3, the structure 2 includes a horizontal frame 8 extending in the first horizontal direction D1. Alternatively, the structure 2 may also include, for example, an upper frame 2a and a first lower frame 2b extending in the second horizontal direction D2, a vertical frame 2c extending in the vertical direction D3 and connecting the upper frame 2a and the first lower frame 2b, and a second lower frame 2d extending in the first horizontal direction D1 and connecting the lower ends of the first lower frame 2b.

[0024] Thus, structure 2 may be a truss structure or girder structure composed of multiple frames 2a to 2d, 8. Although not particularly limited, in this embodiment, for example, the horizontal frame 8 connects the intermediate parts of the vertical frames 2c in the vertical direction D3. Also, although not shown in the figures, structure 2 may include, for example, inclined frames that extend inclined relative to frames 2a to 2d, 8 and connect frames 2a to 2d, 8 to each other, or connecting frames that extend in the second horizontal direction D2 and connect frames (vertical frames 2c, inclined frames) to each other.

[0025] The first horizontal direction D1 is perpendicular to the second horizontal direction D2. For example, in this embodiment, the first horizontal direction D1 is the first horizontal direction X1, the second horizontal direction D2 is the second horizontal direction X2 or the inclination direction X4 (inclination direction X4 in Figure 3), and the vertical direction D3 is the vertical direction X3 or the perpendicular direction X5 (in perpendicular direction X5 in Figure 3).

[0026] Furthermore, in this embodiment, the vertical direction D3 is a direction perpendicular to the first horizontal direction D1 and the second horizontal direction D2, respectively. However, the configuration is not limited to this, and for example, the vertical direction D3 may be a direction that intersects at an angle with respect to at least one of the first horizontal direction D1 and the second horizontal direction D2.

[0027] As shown in Figures 3 and 4, the man conveyor 1 includes a rail 6 extending in a second lateral direction D2 to guide the conveying section 3 from below, and a plurality of holding units 7 arranged in the second lateral direction D2 to hold the rail 6. Note that in Figures 3 and 4, only one holding unit 7 is shown, and only the left half is depicted.

[0028] Furthermore, the man conveyor 1 may also be equipped with a restraining means 1a extending in the second lateral direction D2 to stop the step 3a traveling along the forward path from above, as in this embodiment. This prevents the step 3a from bouncing up while traveling along the forward path by having the restraining means 1a stop the step 3a from above.

[0029] The rail 6 may, for example, as in this embodiment, include a first rail 6a and a second rail 6b that guide the rollers 3e, 3j, and 3k of the transport unit 3 traveling on the forward path from below, and a third rail 6c and a fourth rail 6d that guide the rollers 3e, 3j, and 3k of the transport unit 3 traveling on the return path from below. As a result, the first roller 3e and the second roller 3j connected to the step body 3d are guided by the rails 6a to 6d, thereby guiding the step 3a.

[0030] At this time, rails 6a to 6d will receive a downward load from the transport section 3 (in particular, the weight of step 3a and the weight of a person riding on step 3a as it travels forward). The forward path refers to the area where step 3a is positioned above and travels in the transport direction, allowing for the transport of a person, while the return path refers to the area where step 3a is positioned below and travels in the opposite direction to the transport direction, making it impossible to transport a person.

[0031] Furthermore, the first rail 6a and the second rail 6b may be connected and integrated, for example, as in this embodiment, or they may be separated, for example. Similarly, the third rail 6c and the fourth rail 6d may be separated, for example, as in this embodiment, or they may be connected and integrated, for example.

[0032] The holding unit 7 includes a first clamping body 10 and a second clamping body 20 that clamp the horizontal frame 8 in the second lateral direction D2, an upper clamping fixing part 31 that fixes the first clamping body 10 and the second clamping body 20 above the horizontal frame 8, and a lower clamping fixing part 32 that fixes the first clamping body 10 and the second clamping body 20 below the horizontal frame 8. As a result, the holding unit 7 is fixed to the horizontal frame 8.

[0033] The number of clamping bodies 10, 20 and fixing parts 31, 32 per horizontal frame 8 is not particularly limited. For example, in this embodiment, there are two second clamping bodies 20 per horizontal frame 8, and there are two first clamping bodies 10 and two fixing parts 31, 32 per second clamping body 20 (i.e., there are four first clamping bodies 10 and four fixing parts 31, 32 per horizontal frame 8).

[0034] As shown in Figures 4 to 7, for example, the upper clamping fixing part 31 and the lower clamping fixing part 32 may be male screw fittings (e.g., bolts), the second clamping body 20 may have insertion holes 21 into which the clamping fixing parts 31 and 32 are inserted, and the first clamping body 10 may have a female screw part 11 that screws into the clamping fixing parts 31 and 32. The configuration of the upper clamping fixing part 31 and the lower clamping fixing part 32 is not particularly limited.

[0035] The horizontal frame 8 comprises vertical plate portions 81 arranged along the first horizontal direction D1 and the vertical direction D3, and horizontal plate portions 82 arranged along the first horizontal direction D1 and the second horizontal direction D2. Specifically, the horizontal frame 8 is called, for example, angle steel, L-shaped steel, etc.

[0036] The first clamping body 10 is provided with a recess 12 that is recessed in the second lateral direction D2 and in which the horizontal frame 8 is positioned. The recess 12 may, for example, include a vertical recess 13 in which the vertical plate portion 81 of the horizontal frame 8 is positioned and a horizontal recess 14 in which the horizontal plate portion 82 of the horizontal frame 8 is positioned, as in this embodiment.

[0037] The vertical recess 13 is provided with a first clamping portion 15 that presses against and contacts the vertical plate portion 81 of the horizontal frame 8. The first clamping portion 15 may be formed in a planar shape, as in this embodiment, and arranged along the first horizontal direction D1 and the vertical direction D3.

[0038] Furthermore, the recess 12 includes an upper stopping portion 16 that can stop the horizontal frame 8 from above, and lower stopping portions 17 and 18 that can stop the horizontal frame 8 from below. As a result, when the horizontal frame 8 is positioned inside the recess 12, the upper stopping portion 16 of the recess 12 can stop the horizontal frame 8 from above, and the lower stopping portions 17 and 18 of the recess 12 can stop the horizontal frame 8 from below. Therefore, the first clamping body 10 can be easily positioned on the horizontal frame 8.

[0039] The upper stopper portion 16 may, for example, be provided in the lateral recess 14 and capable of stopping the lateral plate portion 82 from above, as in this embodiment. The lower stopper portions 17 and 18 may, for example, be provided in the vertical recess 13 and capable of stopping the vertical plate portion 81 from below, as in this embodiment, and include a first lower stopper portion 17 provided in the vertical recess 13 and capable of stopping the vertical plate portion 81 from below, and a second lower stopper portion 18 provided in the lateral recess 14 and capable of stopping the lateral plate portion 82 from below.

[0040] The second clamping body 20 includes a second clamping portion 22 that presses against and contacts the vertical plate portion 81 of the horizontal frame 8, and a rail holding portion 23 that holds the rails 6a to 6d. The second clamping body 20 may also include, for example, a restraining holding portion 24 that holds the restraining means 1a, and a railing holding portion 25 that holds the railing portion 4 (for example, although not shown, the guide material of the handrail belt 4a that travels on the return path, or the panel of the cover portion 4c).

[0041] The second clamping portion 22 may be formed in a planar shape, for example, as in this embodiment, and arranged along the first lateral direction D1 and the vertical direction D3. The rail holding portion 23 may include, for example, a first rail holding portion 23a that holds the first rail 6a and the second rail 6b, a second rail holding portion 23b that holds the third rail 6c, and a third rail holding portion 23c that holds the fourth rail 6d, as in this embodiment.

[0042] Furthermore, as in this embodiment, the rail holding parts 23a to 23c may be configured to hold the rails 6a to 6d by supporting them from below. However, the configuration is not limited to this (or, in addition to this configuration), for example, the rail holding parts 23a to 23c may be configured to hold the rails 6a to 6d by fixing them with fasteners 1b (bolts and nuts, etc.; see Figure 3).

[0043] Furthermore, the second clamping body 20 is positioned above the horizontal frame 8 and has female screw holes 26 and 27 extending in the vertical direction D3, and the holding unit 7 has male screw fittings 41 and 42 that screw into the female screw holes 26 and 27. As a result, the amount by which the male screw fittings 41 and 42 protrude downward from the female screw holes 26 and 27 can be changed by screwing them into the female screw holes 26 and 27.

[0044] The female screw holes 26 and 27 consist of a first female screw hole 26 and a second female screw hole 27 that are spaced apart in the first lateral direction D1. The rail holding portions 23a to 23c are positioned between the first female screw hole 26 and the second female screw hole 27 in the first lateral direction D1.

[0045] Furthermore, the male screw fittings 41 and 42 include a first male screw fitting 41 that screws into the first female screw hole 26 and a second male screw fitting 42 that screws into the second female screw hole 27. The rail holding portions 23a to 23c are positioned between the first male screw fitting 41 and the second male screw fitting 42 in the first lateral direction D1.

[0046] The second clamping body 20 may, for example, include a first plate portion 20a and a second plate portion 20b joined in the second lateral direction D2, as in this embodiment. The joining means (not shown) for joining the first plate portion 20a and the second plate portion 20b is not particularly limited and may be, for example, a fastener (screw material), crimping, welding, etc.

[0047] Here, the details of how the retaining unit 7 is fixed to the horizontal frame 8 will be explained with reference to Figures 4-5 and 8-9. Note that the following configuration is provided as an example to aid in understanding the configuration of the retaining unit 7 and the horizontal frame 8, and does not limit the configuration of the retaining unit 7 and the horizontal frame 8.

[0048] As shown in Figure 8, the horizontal frame 8 is positioned inside the recess 12 of the first clamping body 10. Specifically, the vertical plate portion 81 of the horizontal frame 8 is positioned inside the vertical recess 13 of the recess 12, and the horizontal plate portion 82 of the horizontal frame 8 is positioned inside the horizontal recess 14 of the recess 12. At this time, the tip portion 82a of the horizontal plate portion 82 is separated from the inner surface of the recess 12 (specifically, the bottom surface of the horizontal recess 14) in the second lateral direction D2. That is, the tip portion 82a of the horizontal plate portion 82 has a gap with the inner surface of the recess 12 in the second lateral direction D2.

[0049] Furthermore, a portion of the horizontal frame 8 protrudes from the recess 12 of the first clamping body 10 in the second horizontal direction D2. Specifically, a portion of the vertical plate portion 81 of the horizontal frame 8 (the left portion in Figure 8) is located outside the recess 12 of the first clamping body 10, while the other portion of the vertical plate portion 81 of the horizontal frame 8 (the right portion in Figure 8) is located inside the recess 12 of the first clamping body 10.

[0050] Then, the clamping fixing parts 31 and 32 fix the first clamping body 10 and the second clamping body 20, so that the first clamping part 15 of the first clamping body 10 and the second clamping part 22 of the second clamping body 20 press against the vertical plate part 81 of the horizontal frame 8. As a result, the horizontal frame 8 is securely clamped by the first clamping body 10 and the second clamping body 20 in the second horizontal direction D2. Therefore, the holding unit 7 is fixed to the horizontal frame 8.

[0051] Furthermore, the upper clamping fixing part 31 fixes the first clamping body 10 and the second clamping body 20 above the horizontal frame 8, and the lower clamping fixing part 32 fixes the first clamping body 10 and the second clamping body 20 below the horizontal frame 8. As a result, the holding unit 7 can be fixed to the horizontal frame 8 without using the through holes in the horizontal frame 8. Therefore, the holding unit 7 can be fixed to the horizontal frame 8 regardless of whether or not there are through holes in the horizontal frame 8.

[0052] As a result, for example, the holding unit 7 can also be fixed to the horizontal frame 8 of the existing structure 2. For example, it is unknown whether there are through holes in the horizontal frame 8 of the existing structure 2, and the location of the through holes is also unknown. Therefore, for example, first, the existing conveyor components (parts that make up the man conveyor 1, such as rails) are removed from the horizontal frame 8 of the existing structure 2.

[0053] Then, with the first clamping body 10 and the second clamping body 20 clamping the horizontal frame 8 in the second lateral direction D2, the upper clamping fixing part 31 and the lower clamping fixing part 32 fix the first clamping body 10 and the second clamping body 20. After that, the rails 6a to 6d, etc. are held by the second clamping body 20. In this way, the holding unit 7 that holds the rails 6a to 6d, etc. can also be fixed to the horizontal frame 8 of the existing structure 2.

[0054] Incidentally, the insertion hole 21 of the second clamping body 20 extends in the vertical direction D3. Also, since the second clamping body 20 holds the rails 6a to 6d with, for example, the rail holding parts 23a to 23c, the rail holding parts 23a to 23c receive a downward load from the conveying part 3.

[0055] As a result, a downward force is applied to the second clamping body 20, which may cause the second clamping body 20 to shift downward relative to the first clamping body 10. In other words, for example, the second clamping body 20 may shift downward relative to the horizontal frame 8.

[0056] As shown in Figures 4-5 and 9, the male screw fittings 41 and 42 are screwed into the female screw holes 26 and 27 of the second clamping body 20, thereby changing the amount they protrude downward from the female screw holes 26 and 27. The lower ends of the male screw fittings 41 and 42 then press against the horizontal plate portion 82 of the horizontal frame 8 from above, thereby positioning the second clamping body 20 relative to the horizontal frame 8 in the vertical direction D3.

[0057] Furthermore, the rail holding sections 23a to 23c are positioned between the first male screw fitting 41 and the second male screw fitting 42 in the first lateral direction D1. Since the lower ends of each male screw fitting 41 and 42 are pressed against the horizontal plate section 82 of the horizontal frame 8 from above, the downward load received by the rail holding sections 23a to 23c can be received by the first male screw fitting 41 and the second male screw fitting 42.

[0058] This prevents the second clamping body 20 from shifting downward relative to the first clamping body 10 when it is subjected to a downward load from the rail holding parts 23a to 23c. Therefore, it prevents the second clamping body 20 from shifting downward relative to the horizontal frame 8 when it is subjected to a downward load from the rail holding parts 23a to 23c.

[0059] Returning to Figure 3, the man conveyor 1 may also be equipped with a support 1c that supports the second clamping body 20 from below. For example, as in this embodiment, the support 1c may be a male screw (a bolt in Figure 3), the structure 2 (a fixed frame 2e fixed to the vertical frame 2c in Figure 3) may be equipped with a female screw hole that extends in the vertical direction D3 and screws into the support 1c, and the upper end of the support 1c may be configured to stop the second clamping body 20 from below.

[0060] Furthermore, the man conveyor 1 may also include a connector 1d that connects the structure 2 (fixed frame 2e in Figure 3) and the second clamping body 20, as in this embodiment. The connector 1d is not particularly limited, but may include, for example, a bracket, a fastener (e.g., bolts and nuts) for fixing the bracket and the second clamping body 20, and a fastener (e.g., bolts and nuts) for fixing the bracket and the fixed frame 2e, as in this embodiment.

[0061] Furthermore, for example, the horizontal frame 8 (but not limited to, an existing horizontal frame 8) and the second clamping body 20 may each have through holes extending in the second lateral direction D2, and the man conveyor 1 may be provided with fasteners (for example, bolts and nuts; not shown) for fastening the horizontal frame 8 and the second clamping body 20 through these through holes. That is, a part of the holding unit 7 may be fixed to the horizontal frame 8 using the through holes in the horizontal frame 8.

[0062] [1] Based on the above, the man conveyor 1 is as in this embodiment. A structure 2 having a horizontal frame 8 extending in the first horizontal direction D1, A conveyor component that constitutes part of the man conveyor 1 (in this embodiment, the restraining means 1a, the railing 4, and the rail 6), It comprises a holding unit 7 that holds the conveyor components 1a, 4, and 6, The aforementioned holding unit 7 is The first clamping body 10 and the second clamping body 20 sandwich the horizontal frame 8 in a second horizontal direction D2 that is perpendicular to the first horizontal direction D1, An upper clamping fixing part 31 that fixes the first clamping body 10 and the second clamping body 20 above the horizontal frame 8, It includes a lower clamping fixing part 32 that fixes the first clamping body 10 and the second clamping body 20 below the horizontal frame 8. This configuration is preferable.

[0063] With this configuration, the first clamping body 10 and the second clamping body 20 clamp the horizontal frame 8 in the second lateral direction D2. The upper clamping fixing part 31 fixes the first clamping body 10 and the second clamping body 20 above the horizontal frame 8, and the lower clamping fixing part 32 fixes the first clamping body 10 and the second clamping body 20 below the horizontal frame 8. As a result, the holding unit 7 that holds the conveyor components 1a, 4, and 6 can be fixed to the horizontal frame 8 regardless of whether or not there are through holes in the horizontal frame 8.

[0064] [2] Furthermore, in the man conveyor 1 described in [1] above, as in this embodiment, The first clamping body 10 is provided with a recess 12 that is recessed in the second lateral direction D2 and in which the lateral frame 8 is positioned inside, The recessed portion 12 is The aforementioned horizontal frame 8 is secured from above by an upper stopper 16, The horizontal frame 8 is provided with lower stopper parts 17 and 18 that can be applied to and secured from below. This configuration is preferable.

[0065] With this configuration, the first clamping body 10 is provided with a recess 12 that is recessed in the second lateral direction D2. When the horizontal frame 8 is positioned inside the recess 12, the upper stopper 16 of the recess 12 can stop the horizontal frame 8 from above, and the lower stopper 17,18 of the recess 12 can stop the horizontal frame 8 from below. This makes it easy to position the first clamping body 10 on the horizontal frame 8.
