Description

Technical Field

[0001] The present invention relates to a floor structure for a passenger conveyor. Background Art

[0002] Typically, a floor is installed above the flooring of passenger conveyors, with a machine room located beneath the floor. The machine room, for example, is surrounded by a truss structure and houses the drive unit and control panel. During maintenance, inspection, or repairs on passenger conveyors, operators remove the floor and enter the machine room to perform inspections. In other words, the floor of a passenger conveyor serves not only as a display element but also as a door to the interior of the machine room.

[0003] Furthermore, to prevent liquids such as water droplets from dripping through the floor into the machine room, a drip shield is sometimes installed between the floor and the machine room. Japanese Patent Application Publication No. 2012-188268 describes a floor structure in which the floor and drip shield are integrated to reduce the inconvenience of workers entering the machine room for maintenance, inspection, or repairs.

[0007] Problems to be solved by the invention

[0008] The floors of passenger conveyors are often installed on top of the machine room of the passenger conveyor simply by relying on their own weight, and are not mechanically fastened to the outside. However, there are cases where passenger conveyors are grounded to the outdoors or face the outdoors. In such cases, the floors of passenger conveyors may be exposed to strong winds during typhoons, etc. When strong winds blow over the floor, the air pressure near the front of the floor drops, generating negative pressure, and the machine room becomes relatively high. As a result, buoyancy is generated on the floor placed on the machine room. If the floor is not mechanically fastened, when the buoyancy exceeds the weight of the floor, the floor will float. In addition, when the floor is lifted to a height exceeding the thickness, the back of the floor is also blown by the wind. As a result, there is a concern that the floor will detach from the building ground around it.

[0009] One possible solution is to fasten the floor to a lower truss structure. However, mechanically fastening the floor requires additional fastening components, which complicates the structure and increases costs. Furthermore, mechanical fastening has strength limitations, but wind speeds are virtually unlimited, and unexpected buoyancy can act on the floor, potentially causing it to float or detach.

[0010] An object of the present invention is to provide an improved floor structure capable of suppressing detachment of the floor by reducing the pressure difference between the machine room and the outside air, which causes buoyancy, without adding additional members for fastening the floor.

[0011] Means for solving problems

[0012] The floor structure of the passenger conveyor of the present invention is the following floor structure: the floor is arranged at the boarding and alighting area of ​​the passenger conveyor and is used to open and close the upper opening of the machine room below the boarding and alighting area, wherein the floor has: a plurality of holes, which pass through from the front side of the floor serving as the boarding and alighting area to the back side opposite to the machine room; and a groove-shaped guide groove, which is arranged vertically below the plurality of holes and opens toward the plurality of holes.

[0013] Effects of the Invention

[0014] The passenger conveyor floor structure according to the present invention includes multiple holes formed in the floor, extending from the front to the back of the floor, facing the machine room. This allows ventilation through the holes to reduce the pressure difference between the front and back sides of the floor, even if the front of the floor is exposed to strong winds and negative pressure is generated. This effectively prevents the floor from lifting or detaching. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their descriptions are simplified or omitted.

[0023] Implementation method 1.

[0024] Figure 1 and Figure 2 1 is a diagram schematically showing the structure of the passenger conveyor in the vicinity of the boarding and alighting area according to the present embodiment. Figure 1 Shows a cross section parallel to the moving direction and the vertical direction, Figure 2 The upper surface of the passenger conveyor is shown. Figure 1 and Figure 2 In the example shown, an escalator 1 is illustrated as a passenger conveyor. However, the structure of the floor of the passenger conveyor described later can be applied to other passenger conveyors such as moving walkways. Figure 1 and Figure 2 , the structure near the boarding and alighting area of ​​the escalator 1 will be described.

[0025] An escalator 1 is installed across different floors of a building. It is a transportation device that allows users to travel between a boarding and alighting station 2 located on the upper floor and a boarding and alighting station located on the lower floor. The boarding and alighting station 2 on the upper floor and the boarding and alighting station on the lower floor are connected by a moving walkway 3, which allows multiple steps to move. Handrails 4 are arranged on both sides of the moving walkway 3 in the width direction. These handrails 4 have a pair of skirts and moving handrails.

[0026] On the side of the boarding and alighting area 2 of the escalator 1 that is connected to the end of the moving channel 3, comb teeth 5 and a rubber plate 6 extending in the width direction of the escalator 1 are provided. At the boarding and alighting area 2, a floor 10 is installed in a manner connected to the rubber plate 6. The outer peripheral side of the floor 10 is surrounded by the building floor 7 of the boarding and alighting floor. A depression corresponding to the thickness of the floor 10 is formed at the setting position of the floor 10 on the building floor 7, and a frame portion with a seam is formed on the front. By setting the floor 10 in the frame portion, the building floor 7 and the floor 10 are made coplanar. In addition, in order to remove the floor 10, a small gap is formed between the seam of the frame portion and the floor 10. In this embodiment, the floor 10 is in a state of being embedded in the frame portion due to its own weight.

[0027] exist Figure 1 and Figure 2 In the example of FIG, the floor 10 is composed of two pieces, which are arranged on the side close to the moving passage 3 and the back side. On the front of the floor 10 on the side close to the moving passage 3, floor characters indicating the floor numbers of the boarding and alighting areas are displayed.

[0028] The machine room 8 is located below the floor 10. The machine room 8 is a space surrounded by the truss structure 9. The drive engine that drives the escalator 1, the control panel that controls the operation of the escalator 1, and wiring equipment are centrally located within the machine room 8. The floor 10 also functions as the door to the machine room 8. Specifically, during maintenance, inspection, and repair work on the escalator 1, workers can access the interior of the machine room 8 by removing or opening the floor 10.

[0029] Figure 3 and Figure 4 Schematically shows the structure of the floor panel 10 of this embodiment. Figure 3 The front side of the floor panel 10 is shown. Figure 4 Show Figure 3 AA section of floor 10.

[0030] like Figure 3 and Figure 4 As shown, a plurality of holes 12 are formed on the outer periphery of floor 10. Each hole 12 extends vertically through floor 10 from front 10a of floor 10 toward back 10b facing machine room 8. Holes 12 are regularly arranged in multiple rows along the outer periphery of floor 10. In other words, when viewing floor 10 from front 10a or back 10b, a striped lattice pattern is formed along the outer periphery of floor 10.

[0031] The size of each hole 12 (i.e., the surface area of ​​the front surface 10a) is small enough to prevent pedestrians from tripping or getting caught. Furthermore, considering the size of the holes 12, the number of holes 12 is determined so as to ensure sufficient ventilation between the front surface 10a and the back surface 10b of the floor panel 10.

[0032] On the back side 10b of the floor panel 10, a trough-shaped drainage channel 13 is arranged to cover the vertically lower sides of all the holes 12. Specifically, the trough 13 opens facing the back side 10b of the floor panel 10 and is arranged so as to surround the outer periphery of the back side 10b with a width greater than the width of the portion where the holes 12 are formed. The trough 13 has a sufficient capacity to prevent liquids such as rainwater falling from the holes 12 from overflowing.

[0033] A drain port 15 is formed in the rain gutter 13. The drain port 15 is connected to a drain pipe for draining water to the outside. The drain port 15 and the drain pipe are formed with a diameter sufficient to ensure drainage performance so that liquid does not overflow the rain gutter 13. The drain port 15 is formed at a position on the inner circumference side of the portion where the hole 12 is formed so as not to overlap with the portion where the hole 12 is formed in a figure projecting the floor 10 and the rain gutter 13 in the vertical direction. Figure 3 ] A position B obtained by projecting the formation position of the drain port 15 in the vertical direction is shown in FIG.

[0034] The vertical height of the inner peripheral side wall 16 of the rain gutter 13 is lower than the height of the outer peripheral side wall 17. In a cross section perpendicular to the flow direction of rainwater, etc. in the rain gutter 13, the top of the inner peripheral side wall 16 of the rain gutter 13 is separated from the back surface 10b of the floor 10 by a space C.

[0035] According to the structure of the floor panel 10 of this embodiment, a plurality of holes 12 sufficient for ventilation are formed near the periphery of the floor panel 10, and a certain space C is maintained between the side walls 16 of the gutter 13 and the back surface 10b of the floor panel 10. Consequently, even if strong winds blow across the front surface 10a of the floor panel 10, generating a negative pressure there, ventilation between the front surface 10a of the floor panel 10 and the machine room 8 through the holes 12 can reduce the pressure difference between the front surface 10a of the floor panel 10 and the machine room 8. Therefore, even when the floor panel 10 is simply installed in a framed state within the surrounding building floor 7, it is possible to effectively prevent the floor panel 10 from floating or becoming detached due to strong winds.

[0036] Furthermore, a rain gutter 13 is provided vertically below the portion of the floor 10 where the hole 12 is formed. This prevents liquids such as rainwater and foreign matter such as pebbles, sand, and soil falling from the hole 12 from falling into the machine room 8.

[0037] Furthermore, in this embodiment, the holes 12 are arranged in multiple rows in a grid pattern around the periphery of the floor panel 10. This is because, to ensure sufficient ventilation, and structurally, it is simple to place the rain gutters 13 near the periphery of the floor panel 10. However, the arrangement of the holes 12 is not limited to this. As long as the holes 12 are small enough to prevent pedestrians from tripping, and sufficient ventilation is ensured, the holes 12 can be arranged in only one circle around the periphery, or they can be arranged so that the holes 12 form a pattern on the front surface 10a of the floor panel 10. However, while rain gutters 13 are required vertically below all holes 12, if the range of rain gutters 13 is too large, they can actually reduce ventilation. Therefore, it is preferable that the surface area of ​​the portion where the holes 12 are formed is less than 40% to 50% of the surface area of ​​the floor panel 10.

[0038] In this embodiment, the rain gutter 13 is described as a continuous drainage ditch that surrounds the periphery of the floor panel 10, covering the vertically lower sides of the portions where the holes 12 are formed. However, the rain gutter 13 does not need to be a single component, as long as it is located vertically below all the holes 12. For example, it may be a plurality of drainage ditch components installed along each side of the periphery of the floor panel 10.

[0039] In addition, the drain port 15 for discharging the liquid in the rain gutter 13 to the outside is formed at a position avoiding the vertical lower side of the hole 12. As a result, foreign matter that falls through the hole 12 will not fall directly into the drain port 15 and block the drain port 15. However, the formation position of the drain port 15 is not limited to a position closer to the inner circumference than the portion where the hole 12 is formed. As long as the drain port 15 is formed at a position avoiding the vertical lower side of the hole 12, it can also be formed at other positions. In addition, in this embodiment, one drain port 15 is shown for illustration, but the number of drain ports 15 is not restricted, and a structure with multiple drain ports 15 is also possible.

[0040] Furthermore, the floor panel 10 of this embodiment can also be fastened to the truss structure 9 surrounding the machine room 8 by fastening members. When the floor panel 10 is mechanically fastened to the machine room 8, the fastening force and the effect of reducing the air pressure difference by the holes 12 can more reliably suppress the floor panel 10 from floating or detaching.

[0041] In this embodiment, two floor panels 10 are arranged parallel to each other on the side and back of the passage 3. However, the number of floor panels 10 used is not limited to two and can be one or three or more. The size of a single floor panel 10 and the number of floor panels 10 used are determined appropriately based on the width of the boarding area 2 and the structure of the building floor 7 surrounding the boarding area.

[0042] Implementation method 2.

[0043] The structure of the escalator of the second embodiment is the same as that of the escalator 1 of the first embodiment, except that a floor 20 is used instead of the floor 10 . Figure 5 and Figure 6 Schematically shows the structure of the floor panel 20 of this embodiment. Figure 5 Showing the front side of the floor 20, Figure 6 Show Figure 5 DD section.

[0044] like Figure 5 and Figure 6 As shown, the floor panel 20 includes a grille member 21. The grille member 21 is made of steel materials assembled in a grid shape, and thus, a plurality of holes penetrating the front and back surfaces of the grille member 21 are arranged in a grid shape as a whole.

[0045] A front panel 22 having a smaller surface area than that of grille member 21 is attached to the front surface of grille member 21. Floor 20 has a portion uncovered by front panel 22, where grille member 21 is exposed. The holes of grille member 21 in this exposed portion function as holes in floor 20, replacing holes 12 in the first embodiment.

[0046] A rain gutter 23 is provided on the back side of the grille component 21. The rain gutter 23 is a trough-shaped guide ditch, which is arranged on the vertical lower side of the portion of the grille component 21 that is not covered by the front panel 22 and is exposed (hereinafter also referred to as the "exposed portion") in a manner that surrounds the outer peripheral portion of the back side of the grille component 21. That is, the rain gutter 23 is arranged to be partially open toward the back side of the exposed portion of the grille component 21. The rain gutter 23 is formed to be slightly wider than the width of the exposed portion of the grille component 21, and also reaches vertically below the outer peripheral portion of the front panel 22. In addition, a drain outlet 25 is formed in the portion of the rain gutter 23 that is located on the vertical lower side of the front panel 22. Figure 5 ] The position E obtained by projecting the formation position of the drain port 25 in the vertical direction is shown in FIG.

[0047] As with the gutter 13 of Embodiment 1, the vertical height of the inner side wall 26 of the gutter 23 is lower than the height of the outer side wall 27. Thus, a space F is formed between the top of the inner side wall 26 of the gutter 23 and the back surface of the floor 20.

[0048] As described above, by forming the floor 20 using the grille member 21 , similarly to the first embodiment, a pressure difference between the front and back sides of the floor 20 caused by strong winds can be suppressed, thereby suppressing the floor 20 from floating or falling off.

[0049] Furthermore, the rain gutter 23 is disposed vertically below the exposed portion of the grille member 21 of the floor 20. This prevents liquids such as rainwater and foreign matter such as pebbles, sand, and soil that fall from the holes of the grille member 21 from falling into the machine room 8.

[0050] In addition, in this embodiment, the front panel 22 is provided on the inner peripheral side of the grille member 21, and the exposed portion is arranged on the outer peripheral portion of the floor 20. However, the shape, installation location and installation area of ​​the front panel 22 are not limited to Figure 5 and Figure 6 The structure shown. The width of the exposed portion of the grille member 21 can be set to ensure sufficient ventilation. For example, the front panel 22 can be arranged so that the holes of the grille member 21 are only exposed around the periphery. Furthermore, the exposed portions are not limited to being evenly arranged on all four sides of the floor 20. For example, the exposed portions can be formed only on the two widthwise end sides. However, as in the case of the first embodiment, in order to prevent the reduction in ventilation caused by the rain gutter 23 on the back, the area of ​​the exposed portion is preferably set to no more than 40% to 50% of the surface area of ​​the floor 20.

[0051] As in the first embodiment, the rain gutter 23 is not limited to surrounding the outer periphery of the floor 20. The rain gutter 23 may be a plurality of divided ditches provided on the floor 20, as long as it is arranged vertically below the entire exposed portion.

[0052] The formation position of the drain port 25 of the rain gutter 23 is not limited to the position below the exposed portion. Figure 5 and Figure 6 In addition, the number of the drain port 25 is not limited, and a structure having a plurality of drain ports 25 may also be used.

[0053] Furthermore, the floor 20 of this embodiment can also be fastened to the truss structure 9 surrounding the machine room 8 by fastening members, similarly to the case of Embodiment 1. The number of floor panels 20 is not limited to two, and may be one or three or more.

[0054] Implementation method 3.

[0055] The structure of the floor panel 10 according to the third embodiment is the same as that of the floor panel 10 according to the first embodiment, except that a guide 31 is formed on the back surface 10 b side of the floor panel 10 . Figure 7 This is a cross-sectional view showing the structure of the floor panel according to the third embodiment. Figure 4 The corresponding cross section.

[0056] like Figure 7 As shown, the guide 31 is a rod-shaped member and is disposed on the innermost circumference of the portion where the holes 12 are formed on the back surface 10b of the floor 10. In other words, the guide 31 is disposed on the inner circumference of the innermost row of holes 12 formed in the floor 10 so as to protrude toward the gutter 13.

[0057] Without guide 31, there is a concern that liquid and foreign matter falling from hole 12 may be moved by wind before reaching gutter 13, falling to a location deviating from gutter 13 or moving along back surface 10b of floor 10 and falling into machine room 8. In contrast, according to Embodiment 3, liquid and foreign matter falling from hole 12 are guided to gutter 13 by guide 31. This more reliably prevents the falling matter from deviating from gutter 13 and falling into machine room 8.

[0058] The guides 31 may be provided only in the holes 12 arranged on the innermost circumference side, or may be provided in all the holes 12. Furthermore, the guides 31 may be provided only in any of the holes 12 among the plurality of holes 12.

[0059] In addition, the guide 31 is not limited to a rod-shaped member, and may be, for example, a protrusion-shaped member that protrudes toward the gutter 13 .

[0060] Furthermore, while the guide 31 is provided on the floor panel 10 of the first embodiment, the guide 31 may also be formed on the floor panel 20 of the second embodiment. Specifically, the guide 31 may be disposed on the back side of the hole located at the exposed portion of the grille member 21 of the floor panel 20 of the second embodiment.
