Description

[Technical field]

[0001] The present invention relates to passenger conveyors such as escalators and moving walkways and repair methods thereof, and more particularly to the structure of a boarding and alighting floor provided at a boarding and alighting entrance and a repair method thereof. [Background technology]

[0002] The boarding and alighting floor installed at the entrance and exit of an escalator, which is a type of passenger conveyor, generally comprises a decorative plate that forms the tread surface, and a frame body of a sheet metal structure attached to the back surface of the decorative plate and constructed by overlapping many parts formed from thin steel plates.

[0003] Furthermore, when escalator users walk on the boarding and alighting floor, the decorative panels that form the tread surface wear away due to friction caused by walking, reducing the frictional resistance. In such cases, the boarding and alighting floor is repaired and replaced to prevent users from falling and ensure their safety. In addition, boarding and alighting floors are also repaired and replaced as part of general maintenance when they become dirty, scratched, or deformed. It is desirable to reduce the frequency of such repairs and replacements, the number of parts, and the labor required for replacement.

[0004] The boarding and alighting floor is part of the floor plate and also functions as a door to access the escalator machine room for maintenance work. If this door is heavy, the labor required to open and close it is a burden for the workers who need to enter and exit the machine room, so it is desirable to reduce this burden. In response to this, a passenger conveyor has been proposed that is equipped with a boarding and alighting floor that can be changed to a width that corresponds to various widths of passenger conveyors, has a structure that allows easy replacement of decorative panels due to wear, and is lightweight.

[0005] For example, the boarding and alighting floor disclosed in Patent Document 1 is composed of a decorative plate made of a thin steel plate having an uneven surface and a frame body to which the decorative plate is attached. The frame body of this boarding and alighting floor is formed of a continuous body with the same cross-sectional shape, and the continuous body can be cut to a size corresponding to the width of the passenger conveyor.

[0006] [Patent Document 1] JP 2012-1290 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, according to the technology disclosed in the above-mentioned Patent Document 1, in order to stably attach and fix the decorative panel to the frame body, in addition to inserting a flat head screw through a through hole provided on the surface of the decorative panel and fastening it to a screw hole provided on the frame body, the decorative panel is also attached to the frame body using double-sided tape or adhesive to prevent partial lifting of the decorative panel. Since the decorative panel is attached in this way, peeling it off often damages the frame body to the extent that it bends, unless great care is taken. For this reason, every time the decorative panel wears out significantly, it becomes necessary to replace the entire boarding floor, including the frame body to which the decorative panel is attached.

[0008] SUMMARY OF THE PRESENT EMBODIMENT The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a passenger conveyor that reduces the frequency of changing boarding and alighting floors. [Means for solving the problem]

[0009] The present invention, which solves the above-mentioned problems, provides a passenger conveyor equipped with boarding and alighting floors that cover machine rooms provided at both the front and rear longitudinal ends of the frame, and a carrier that circulates between the boarding and alighting floors and is endlessly connected between them, in which the boarding and alighting floor has a box-shaped structure formed partly or entirely of a flat rectangular prism consisting of a first plane that is installed horizontally, a second plane opposite the first plane, and the remaining vertical plane, and the boarding and alighting floor has a reversible structure in which either the first plane or the second plane can be used as the surface of the boarding and alighting floor. Effect of the Invention

[0010] According to the present invention, a passenger conveyor can be provided that reduces the frequency of changing boarding and alighting floors. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. The following description and drawings are examples for explaining the present invention, and may be omitted or simplified as appropriate for clarity of explanation. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0013] The present invention is not limited to the embodiments, and all application examples that conform to the concept of the present invention are included in the technical scope of the present invention. Those skilled in the art can make various additions and modifications to the present invention within the scope of the present invention. The present invention can be implemented in various other forms. Unless otherwise specified, each component may be multiple or singular.

[0014] Fig. 1 is a side cross-sectional view showing the overall configuration of an escalator as a passenger conveyor according to an embodiment of the present invention. As shown in Fig. 1, in the escalator 1 according to this embodiment, a number of steps (carriers) 2 are endlessly connected and circulated to transport passengers between an upper floor 3 and a lower floor 4. Note that the same reference numerals are used for the escalators 1 as the passenger conveyor 1.

[0015] This escalator 1 comprises a frame 5 installed in an architectural structure, a handrail 6 which is provided for the safety of passengers and moves in sync with the steps 2, and a balustrade 7 which is located on both sides of the width of the steps 2 to support the handrail 6 and which is erected along the longitudinal direction Y of the frame 5 (the direction in which users travel).

[0016] The upper level boarding / alighting floor 8 and the lower level boarding / alighting floor 9, the handrails 6, the balustrade 7, etc. are supported by the frame 5, and the boarding / alighting entrances on the building side are fixed to both longitudinal ends of the frame 5. These boarding / alighting entrances include the upper level boarding / alighting floor 8 and the lower level boarding / alighting floor 9, and are collectively referred to as the boarding / alighting floors 8, 9. The boarding / alighting floors 8, 9 are not limited to the escalator 1, but are also applied to moving walkways. Here, the boarding / alighting floors 8, 9 used in the escalator 1 will be explained in more detail.

[0017] The width direction of the boarding and alighting floors 8, 9 is the X direction (Fig. 3) perpendicular to the longitudinal direction Y of the frame 5. In other words, it refers to the direction perpendicular to the plane of Fig. 1. The frame 5 of the escalator 1 has an upper boarding and alighting floor 8 and a lower boarding and alighting floor 9 where users get on and off, and an inclined section 10 connecting these. Also, a driving machine 12 is installed in an upper machine room 11 in the upper boarding and alighting floor 8, and drives a driving sprocket 13.

[0018] On the other hand, a driven sprocket 15 is installed in the lower floor machine room 14 in the lower floor boarding / disembarking floor 9, and an endless chain 16 is wound around the upper and lower driving sprockets 13 and driven sprockets 14 to drive them continuously. Axles 17 are connected to this chain 16 at equal intervals, and each step 2 is attached to the axles 17. The upper floor machine room 11 and the lower floor machine room 14 are collectively referred to as the upper and lower floor machine rooms 11, 14, or the escalator machine rooms 11, 14, or simply the machine rooms 11, 14.

[0019] The conventional boarding and alighting floor disclosed in Patent Document 1 was composed of two main components: a frame that supports passenger loads, etc., and a decorative plate that is attached to the surface of the frame to form the tread. This decorative plate is made using common techniques, such as by stamping out a thin steel plate such as stainless steel into an uneven shape, or by etching the surface to make it uneven, and is a structure that ensures a certain level of friction against the soles of passengers' shoes, in addition to providing a moderate design effect as the name "decorative plate" implies.

[0020] In contrast, the boarding and alighting floors 8, 9 in the escalator 1 according to the embodiment of the present invention are not provided with decorative panels, and are basically constructed only of a single component frame 18. Fig. 2 is a partially enlarged cross-sectional side view for explaining the installation form and external shape of the boarding and alighting floors in the escalator in Fig. 1.

[0021] The boarding and alighting floors 8, 9 have a substantially identical cross-sectional shape in the width direction, and are stretched by an arbitrary length L in the depth direction relative to the paper plane of Figs. 1 and 2, i.e., in the width direction X described later with reference to Fig. 3, to form a frame body 18 (reference numeral 19 in Fig. 3). As described above, the frame body 18 (19) constitutes the boarding and alighting floors 8, 9 as a single item. In this way, the boarding and alighting floors 8, 9 constituted as a single item by the frame body 18 (19) are the same, but are given different reference numerals for the convenience of explaining their functions. In other words, these boarding and alighting floors 8, 9 function as floor covers for the machine rooms 11, 14. The frame body 18 (19) refers to a rigid floor cover structure.

[0022] The frames 18, 19 are manufactured by a method such as extrusion molding using aluminum or the like, that is, the frames 18, 19 as the boarding and alighting floors 8, 9 have substantially the same cross-sectional shape cut along a plane perpendicular to the width direction X at any position in the width direction X, and constitute a continuous formed body in the width direction X. The frames 18, 19 are flat rectangular parallelepipeds formed into a box structure partially or entirely. Note that it is not necessary for all six faces constituting the box structure to have a sealing function, and for example, two opposing faces may be open and nearly hollow.

[0023] In addition, in the boarding and alighting floors 8, 9 of the passenger conveyor 1, the frame bodies 18, 19 formed as a continuum have a plurality of grooves 20 or protruding strips 21 formed in parallel and densely on each of two faces, the upper first plane A and the lower second plane B, which are installed horizontally (omitted in FIG. 3). One of these, the first plane A, is initially exposed in a state of being fixed facing upward as the boarding and alighting floors 8, 9. Note that when a plurality of grooves 20 or protruding strips 21 are formed in parallel and densely, they are continuous grooves and continuous protruding strips, and either name is essentially the same.

[0024] At this time, the first plane A needs to guarantee a certain frictional force against the soles of passengers' shoes to ensure safety, just like the tread of the circulating steps 2. The other, second plane B, faces downward and is placed so as to cover the ceiling of the machine rooms 11, 14, and the edge of the second plane B is supported by the floor frame 22 (part of the frame 5) via a cushioning material 23. At this time, not only does the second plane B need not guarantee a frictional force against the soles of passengers' shoes, but it does not need to be aesthetically pleasing either, as it is not exposed.

[0025] Among the above, from the viewpoint of ensuring safety, the multiple parallel and densely formed grooves 20 or ridges 21 are beneficial because they have the function of preventing slipping and falling. Furthermore, from the viewpoint of structural strength, the ridges 21 provided on the flat plate surface are beneficial because they have the function of reinforcing the frame body 18 as ribs or corrugated plates. Furthermore, from the viewpoint of design, a certain degree of aesthetic appeal can be expected. The frames 18, 19 as boarding and disembarking floors are required to have all of the friction, strength, and aesthetic appeal for the upward exposed surface according to the required functions, but the downward hidden surface does not require friction or aesthetic appeal.

[0026] These grooves 20 or ridges 21 have the same cross-sectional shape and can be mass-produced accurately and easily in a continuous body manufactured by extrusion molding using aluminum as the material. In this passenger conveyor 1, the boarding and alighting floors 8, 9 have a basic external shape of a flat rectangular parallelepiped, and are formed by six surfaces, namely, two surfaces, the first plane A and the second plane B, which are installed horizontally, and the remaining four surfaces, the vertical planes C to F. The boarding and alighting floors 8, 9 are shaped so that the area average of the first plane A and the second plane B is the same for the frictional force against the soles of passengers' shoes. The reason for using the area average is that it includes cases where the design does not necessarily provide uniform surface friction over the entire surface.

[0027] Furthermore, the boarding and alighting floors 8, 9 are flat rectangular parallelepipeds with the same configuration on both sides. That is, the first plane A and the second plane B, which are installed horizontally, are the same shape, and on both surfaces, the grooves 20 or the protruding strips 21 have the same cross-sectional shape and are manufactured by extrusion molding as a continuous body. With this manufacturing method, the burden of making the front and back of a flat rectangular parallelepiped with the same configuration remains the same, and this contributes to improving manufacturability overall.

[0028] Therefore, in the passenger conveyor 1, when one of the first plane A and the second plane B of the boarding and alighting floors 8, 9 deteriorates to the extent that replacement is required, the boarding and alighting floors 8, 9 can be turned over and reinstalled as long as the other is of usable quality. In this way, in the passenger conveyor 1, the boarding and alighting floors 8, 9 have a reduced number of parts, improved manufacturability, and doubled lifespan.

[0029] In this way, the boarding and alighting floors 8, 9 can be easily maintained in response to wear, and by increasing the number of times they are used and extending their lifespan, materials can be saved and the labor required for storing, transporting and providing those materials can be reduced. In other words, this contributes to reducing the variety, quantity, storage period and maintenance personnel required for spare parts.

[0030] Here, the mainstream escalator type has a step width of about 1000 mm, but there are also 600 mm or 800 mm types depending on the building size or the number of users. Naturally, the width dimensions of the boarding and alighting floors 8, 9 will also change according to the escalator type. Figure 3 is a perspective view for explaining the diagonal rails of the boarding and alighting floor in a modified example.

[0031] The boarding / alighting floor 9 (8) shown in FIG. 2 is formed by extruding aluminum, forming the frame body 18 as a continuous body with approximately the same cross-sectional shape. The boarding / alighting floor 9 (8) with such a structure can suppress the overall mass from becoming heavy by forming the wall thickness uniformly thin, and is an effective configuration when removing the boarding / alighting floor 9 (8) to enter the escalator machine room 11, 14 for maintenance work, etc. The upper and lower planes A and B installed horizontally on the frame body 18 are continuous bodies with approximately the same surface shape, and the front and back surfaces A and B have the load resistance as tread surfaces. In other words, the boarding / alighting floor 9 (8) made of the frame body 18 has a strength such that the upper plane A does not deform even when stepped on by a person, and also has a strength such that the lower plane B installed opposite the floor frame 22 does not deform.

[0032] The frame body 19 according to the modified example of Fig. 3 is formed of a continuous body having a substantially uniform cross-sectional shape in the width direction, so that the width dimension L of the frame body 19 can be easily changed by cutting the long continuous body to the required length. This makes it easy to provide escalator boarding and alighting floors 8, 9 with a wide variety of widths. As can be seen from a cross section cut in the travel direction Y of the user (the longitudinal direction of the frame 5), this frame body 19 is formed of a cavity 28, a diagonal side 27, a vertical side 24, an upper side 25, and a lower side 26.

[0033] In other words, by having substantially the same cross-sectional shape with oblique side 27, having multiple triangular cavities 28 in cross section in the width direction X of boarding and alighting floors 8, 9, and using aluminum or other materials, even if frame body 19 is formed as a continuous body of substantially the same cross-sectional shape, the overall mass can be prevented from becoming heavy, and this configuration is effective when boarding and alighting floors 8, 9 are removed to enter the escalator machine room for maintenance work, etc.

[0034] Furthermore, the substantially uniform cross-sectional shape of the frame 19 is a triangular cross-sectional shape having a vertical side 24 as well as a diagonal side 27 (a so-called truss structure is adopted), which is effective in effectively distributing the load from users passing over the boarding and alighting floors 8, 9 to the entire frame 19 and ensuring the necessary structural rigidity for the main bodies of the boarding and alighting floors 8, 9. The vertical side 24 and the diagonal side 27 are respectively disposed perpendicularly and diagonally to the user travel direction Y of the boarding and alighting floors 8, 9.

[0035] As described above, in the above embodiment, the escalator 1 has been taken as an example, but similar boarding and alighting floors 8, 9 are generally used in other passenger conveyors such as moving walkways, and further, since the frame body is formed as a continuous body having substantially the same cross-sectional shape, it has versatility in that the width dimension L of the frame body 19 can be easily changed by cutting it according to the required length, and it can be easily applied to wide moving walkways, etc. In this way, the passenger conveyor according to the embodiment of the present invention can be applied to moving walkways, etc. in addition to the escalator 1.

[0036] [Comparative Example] Next, a brief description will be given of a boarding / alighting floor 30 according to a comparative example with reference to Fig. 4. Fig. 4 is a cross-sectional view showing an enlarged part of a cut surface of the boarding / alighting floor 30 cut in the travelling direction Y of the user. The boarding / alighting floor 30 made of a steel plate is attached to the floor frame 22 via a reinforcing member 31 attached with a double-sided tape 32 in order to obtain rigidity against the weight of passengers and bending stress caused by stepping on it. This boarding / alighting floor 30 may have the above-mentioned decorative plate (not shown) attached to the top layer in order to ensure frictional force between the upper flat surface and the soles of passengers' shoes, but the grooves 20 and the ridges 21 shown in Fig. 2 may be formed on the surface of the boarding / alighting floor 30.

[0037] In the case where the grooves 20, the ridges 21, etc. are formed on the surface of the boarding / alighting floor 30 and the boarding / alighting floor 30 is attached to other components with double-sided tape 32, the following problem occurs. That is, when the upper flat surface of the boarding / alighting floor 30 is damaged and the bonding surface, i.e., the lower flat surface, is peeled off from the reinforcing material 31 for maintenance, that is, when the frame is disassembled, it is known that even if considerable care is taken, the frame that is to be left as the reinforcing material 31 can be damaged.

[0038] In addition, the structure of the boarding and alighting floor 30 is a complex sheet metal structure formed by stacking many parts formed from thin steel plates as a frame. In order to repair and replace such a complex structure with many parts, a considerable amount of materials and labor are required. Therefore, it is difficult to adopt a life-extending method of turning the entire boarding and alighting floor 30 over to make the lower plane the upper plane and expose a newly usable surface, even if the upper plane becomes damaged after a certain period of use. In this way, the structure of the boarding and alighting floor 30 cannot be designed in advance to have the same friction force on the passenger's shoe sole on each of the upper and lower planes.

[0039] In contrast, the boarding and alighting floors 8, 9 according to the embodiment of the present invention, of the two surfaces, the first plane A and the second plane B, which are upper and lower and are in a front-back relationship, when one of the surfaces initially installed so as to be exposed upward, i.e., the upper plane A, deteriorates to the extent that it requires replacement, it is possible to turn the boarding and alighting floors 8, 9 over and reinstall them, provided that the other surface, i.e., the lower plane B, is of a usable quality. The effects of this have already been explained.

[0040] The passenger conveyor 1 according to the embodiment of the present invention can be summarized as follows. [1] The passenger conveyor 1 is configured with machine rooms 11, 14 provided at both front and rear ends in the longitudinal direction of the frame 5, boarding and alighting floors 8, 9 that cover the machine rooms 11, 14, and a carrier 2 that circulates between the boarding and alighting floors 8, 9 in an endless manner. The boarding and alighting floors 8, 9 are box-shaped structures formed partly or entirely of a flat rectangular parallelepiped with a first plane A installed horizontally, a second plane B facing the first plane A, and the remaining vertical planes C to F. In this way, the boarding and alighting floors 8, 9 are box-shaped structures with load-bearing properties as tread surfaces on the front and back faces A and B, so that they have the strength to not deform even on the lower plane B installed opposite the floor frame 22. The passenger conveyor 1 also includes a moving walkway in which the carrier 2 is made of a rubber belt or the like.

[0041] The boarding and alighting floors 8, 9 have a reversible structure in which either the first plane A or the second plane B can be used as the surface of the boarding and alighting floor. In other words, the first plane A and the second plane B have a reversible structure in which the surface friction force is the same on the average area of ​​each plane, and therefore each plane has a backup function. Therefore, in the passenger conveyor 1, the boarding and alighting floors 8, 9 can be installed even if the upper and lower planes are turned upside down. In other words, the boarding and alighting floors 8, 9 are basically formed by a flattened rectangular parallelepiped. The upper and lower planes of the flattened rectangular parallelepiped have a shape in which the friction force against the soles of passengers is the same on the average area of ​​each plane. The boarding and alighting floors 8, 9 may have a tapered structure in which the end sides of the box structure are inclined, or may have a shape in which the upper side converges in a parabola and the corners are rounded in the Y-direction cross section. Furthermore, the present invention also includes slight variations in the shape of the first plane A and the second plane B, so long as the shape satisfies both the viewpoint of ensuring safety through frictional force and the viewpoint of appearance.

[0042] Therefore, in the passenger conveyor 1, when one of the first plane A and the second plane B, i.e., the upper plane A, deteriorates to the extent that replacement is required, the boarding and alighting floors 8, 9 can be turned over and reinstalled if the other plane, i.e., the lower plane B, is of a usable quality. In this way, the boarding and alighting floors 8, 9 in the passenger conveyor 1 have a reduced number of parts and are easier to manufacture. These boarding and alighting floors can be easily maintained in response to wear, and can save materials by increasing the number of times they are used to extend their lifespan, reducing the labor required for storing, transporting, and managing the materials as needed.

[0043] [2] The passenger conveyor 1 preferably further includes a balustrade 7 located on both sides of the width direction X of the conveyor 2 and erected along the longitudinal direction of the frame 5, a handrail 6 driven in synchronization with the conveyor 2, and a boarding / alighting floor support structure. In the boarding / alighting floors 8, 9 of the passenger conveyor 1, the first plane A and the second plane B preferably have the same surface shape. This can reduce the time and effort required for design, production of molds, etc., and inspection, which can contribute to improving overall manufacturability. In addition, even if a defective product has minor scratches on either the first plane A or the second plane B, the other surface without scratches can be used as an acceptable product. In addition, the boarding / alighting floor support structure is a structure in which the boarding / alighting floors 8, 9 are placed in contact with the surfaces of the boarding / alighting floors 8, 9 on the floor frames 22 formed on the upper planes at both ends of the frame 5.

[0044] [3] Of the four vertical surfaces C to F, two opposing surfaces C and D are formed from a continuous body of the same cross-sectional shape. This continuous body can be cut to a size corresponding to the width of the step 2. Products molded from such a continuous body are easy to mass-produce to the same standard and are easy to procure.

[0045] [4] In the passenger conveyor 1, the continuous body is manufactured by extrusion molding using aluminum as the material. Due to extrusion molding, the continuous body can be formed into a rectangular parallelepiped of any length with the same cross-sectional shape. The cross-sectional shape forms a hollow space surrounded by two faces, the first plane A and the second plane B, and two faces E and F of the four vertical faces C to F. In this way, in the continuous body manufactured by extrusion molding using aluminum as the material, the boarding and alighting floors 8 and 9 can be mass-produced accurately and easily.

[0046] [5] The cross-sectional shape of the continuum forming the boarding and disembarking floors 8, 9 is a rectangle surrounded by two of the sides forming the two upper and lower faces A, B, and two of the sides forming the four vertical faces C to F. It is preferable that vertical, horizontal, or diagonal bars are formed on this rectangular cross-sectional shape. The continuum manufactured by extrusion molding with a rectangular cross-sectional shape made of aluminum as described above in [4] is box-shaped, and a cross-bar frame is formed inside the box-shaped shape, which makes it possible to further enhance its robustness.

[0047] [6] In the passenger conveyor 1, a plurality of grooves 20 or ridges 21 are formed in parallel on each of the two surfaces of the first plane A and the second plane B of the continuous body. These grooves 20 or ridges have the same cross-sectional shape, and can be accurately and easily mass-produced in the continuous body manufactured by extrusion molding using aluminum as the material described in [4] above. [7] This passenger conveyor 1 is suitable as an escalator, and the steps 2 of the escalator are the carriers 2 described above in [1] to [6].

[0048] The repair method for the passenger conveyor 1 according to the embodiment of the present invention (the present method) can be summarized as follows. [8] This method is a method for repairing the boarding and alighting floors 8, 9 that have been damaged with use in the passenger conveyor 1 described in [1] above, which has boarding and alighting floors 8, 9 that cover the machine rooms 11, 14. The boarding and alighting floors 8, 9 have a box-shaped structure. In such boarding and alighting floors 8, 9 with a box-shaped structure, the first plane A and the second plane B are in a relationship in which one plane is used as a repair part for the other plane when it is damaged. In other words, if one plane is damaged, the undamaged other plane can take over its role.

[0049] In other words, the frictional force against the soles of passengers' shoes is the same for the average area of ​​the first plane A and the second plane B when they are unused, and they perform a backup function for each other. Therefore, when the upper plane A of the boarding and alighting floors 8, 9, which have a basic outline of a flat rectangular parallelepiped, becomes worn enough to require replacement and becomes slippery, if the lower plane B is of the same quality as a new one, the boarding and alighting floors 8, 9 can be reinstalled upside down with plane B facing up and plane A facing down.

[0050] Thus, according to this method, the boarding and alighting floor is simple and easy to maintain, and by increasing the number of times it can be used and extending its life, it is possible to save on materials and reduce the labor required for handling it. [Explanation of symbols]
