Description

  The present invention relates to passenger conveyors such as escalators and moving walkways, and more particularly to a configuration of a boarding / alighting floor provided at a boarding / exiting gate.

  A boarding / alighting floor provided at an entrance / exit of an escalator, which is a type of passenger conveyor, is generally configured by laminating a decorative plate that forms a tread surface and a number of parts that are provided on the back surface of the decorative plate and formed of a thin steel plate. A main frame having a sheet metal structure. In addition, a boarding / alighting floor requires a large number of types of boarding / alighting floor widths in accordance with the specifications of the escalator, and it is common to manufacture a boarding / alighting floor corresponding to each boarding / alighting floor width.

  In addition, escalator users walk on this boarding / exiting floor, but if the decorative board forming the tread surface is worn due to friction from walking, etc., the boarding / exiting floor will be used to prevent the user from falling due to reduced frictional resistance. It is a general situation that is required to exchange.

  Furthermore, the getting-on / off floor opens and closes when entering and exiting the escalator's machine room for maintenance work. Since the weight of the getting-on / off floor is heavy, it is indispensable to reduce the burden on workers.

  Therefore, as a conventional technique for improving the maintenance work of the entrance / exit floor plate of the passenger conveyor composed of the decorative plate and the back plate for fixing the decorative plate, for example, as disclosed in Patent Document 1, a decorative plate is used. It has been proposed to divide into a plurality of pieces and attach each of the divided decorative plates to the back plate in a detachable manner.

  However, the main frame body of the conventional boarding / exiting floor described above is a sheet metal structure formed by superimposing parts formed by thin steel plates, so that it has many parts, the weight increases, and further the width of each passenger conveyor In order to cope with this, there are problems such as an increase in the number of types of parts because the dimensions of individual parts also change. Furthermore, when the surface of the decorative board forming the tread of the boarding / exiting floor is worn due to friction caused by the user's walking, the boarding / exiting floor is required to be replaced, and the boarding / exiting floor itself is replaced.

  Further, in the technique disclosed in Patent Document 1 above, no consideration is given to the width of the boarding floor with respect to the dimensions of the backboard to which a large number of decorative plates are attached. There is a problem in the maintenance work for changing the boarding / exiting floor due to the heavy weight.

  The object of the present invention is to reduce the number of parts and improve the manufacturability of the boarding / alighting floor, to change the boarding / alighting floor width corresponding to the width of various passenger conveyors, and to easily change the decorative board due to wear, and to have a mass. It is providing the passenger conveyor provided with the boarding / alighting floor which can reduce.

In order to solve the above problems, the present invention mainly adopts the following configuration.

  First, the whole structure of the escalator as a passenger conveyor which concerns on embodiment of this invention is demonstrated below, referring FIG. In the escalator 1 relating to the present embodiment, a large number of steps 2 are connected endlessly and circulated, and passengers are transported between the upper floor 3 and the lower floor 4. In addition, the escalator 1 is positioned on both sides in the width direction of the step 2, a frame (frame body) 5 installed in the building structure, a handrail 6 that is provided for passenger safety and moves in synchronization with the step 2. A balustrade 7 that supports the handrail 6 and is erected along the longitudinal direction of the frame 5. In addition, the width direction of the getting on / off floors 8 and 9 refers to the longitudinal direction of the getting on / off floors 8 and 9, in other words, the direction perpendicular to the plane of FIG. The boarding / exiting floors 8 and 9, the handrail 6, the balustrade 7, and the like are supported by the frame 5, and the building-side boarding entrances (specifically, the upper floor boarding / exiting floor 8 and the lower floor) The boarding / exiting floor 9) is fixed.

  The frame 5 of the escalator 1 includes an upper floor getting on / off floor 8 and a lower floor getting on / off floor 9 on which a user gets on and off, and an inclined portion 10 that connects these. Further, a drive machine 12 is installed in the upper floor machine room 11 in the upper floor getting on / off floor 8 to drive the drive sprocket 13. On the other hand, a driven sprocket 15 is installed in the lower floor machine room 14 in the lower floor getting-on / off floor 9, and an endless chain 16 is wound between the upper and lower drive sprockets 13 and the driven sprocket 14 to drive continuously. It is supposed to be.

  An axle 17 is connected to the chain 16 at equal intervals, and each step 2 is attached to the axle 17.

  Next, FIG. 2 is an enlarged perspective view showing a configuration of an getting-on / off floor of an escalator as a passenger conveyor according to the first embodiment of the present invention. Here, the meaning of the term “getting on and off” in this specification includes those on an escalator and those on a moving sidewalk. In this embodiment, the boarding and getting off floors 8 and 9 used for the escalator will be described.

  The boarding / alighting floors 8 and 9 in the present embodiment are mainly composed of a decorative board 18 that forms a tread surface, and a main frame 19 that is provided on the back surface of the decorative board 18 and supports passenger loads and the like. The decorative plate 18 has a structure using a general technique such as a material formed by punching a thin steel plate such as stainless steel into a concavo-convex shape, or a surface having a concavo-convex shape by an etching process.

  On the other hand, the main frame 19 which is the main frame in the present embodiment is manufactured by a method such as extrusion using aluminum or the like as a material, and has substantially the same cross section in the width direction of the landing floors 8 and 9 as shown in FIG. It is formed of a continuous body such as a shape. That is, the main frame 19 in the getting-on / off floor has a substantially identical cross-sectional shape cut in a cross-section in the width direction and the vertical direction at any position in the width direction, and constitutes a formed body continuous in the width direction. Is. In addition, in FIG. 3 mentioned later, the structural example which divides the continuous formation body (namely, continuous body) into three is shown. If an attempt is made to produce this continuous body having substantially the same cross-sectional shape by aluminum die casting, the facility becomes enormous, so it is not very suitable.

  Here, the escalator type has a main step width of about 1000 mm, but there are also 600 mm and 800 mm when the number of users and the number of users is small. Naturally, the width dimension of the getting-on / off floors 8 and 9 changes according to the escalator type, but as shown in FIG. 3, the getting-on / off floors 8 and 9 of the present embodiment have the main frame 19 in the width direction. Since it is formed of a continuous body having substantially the same cross-sectional shape, the width dimension L of the main frame body 19 can be easily changed by cutting and using it according to the required length. Therefore, it is easy to provide the escalator landing floors 8 and 9 with a wide variety of widths.

  Further, the main frame body 19 of the present embodiment can be seen from the cut surface cut in the user's traveling direction (direction perpendicular to the width direction shown in FIG. 2) (FIG. 2 and FIG. 4 described later). As can be seen from FIG. 2, the cavity 21, the oblique side 20, the vertical side 40, the upper side 41, and the lower side 42 are formed. The cross section has a plurality of triangular cavities 21 and is made of aluminum or the like, so that even if the main frame 19 is formed of a continuous body having substantially the same cross-sectional shape, the overall mass becomes heavy. This is a configuration that can be suppressed, and is effective when the occupant floors 8 and 9 are attached and detached because they enter the escalator machine room for maintenance work or the like.

  In addition, since the substantially same cross-sectional shape of the present embodiment is a triangular cross-sectional shape having a hypotenuse 20 in addition to the vertical side 40 (a so-called truss structure is adopted), it passes over the landing floors 8 and 9. It is effective to effectively distribute the load from the user to the main frame body 19 and to secure the rigidity necessary for the structure of the main bodies 8 and 9. The vertical side 40 and the oblique side 20 are respectively arranged in a vertical direction and an oblique direction with respect to the user traveling direction of the getting-on / off floor.

  In addition, as shown in FIG. 4, the decorative plate 18 and the main frame 19 are fixed by providing a screw-shaped shaft 22 on the back surface of the decorative plate 18 and inserting the shaft into the through hole 23 of the main frame 19. The nut 24 is fixed. As another fixing method, as shown in FIG. 5, a countersunk screw 25 may be inserted from a through hole provided on the surface of the decorative plate 18 and fastened to a screw hole provided in the main frame 19. Further, in this fixing method, fixing may be performed using a double-sided tape or an adhesive.

  Next, the structure of the getting-on / off floor of the escalator as a passenger conveyor which concerns on the 2nd Embodiment of this invention is demonstrated below, referring FIGS. 2nd Embodiment is an example at the time of making the cross-sectional shape of the main frame 19a which mounts the decorative board 18 into another structure, From the board thickness of the decorative board 18 to the both ends of the user advancing direction of the main frame 19a. A slightly larger groove 26 (a hook portion, a fitting portion, or a U-shaped portion) is provided. By providing the groove 26, the decorative plate 18 can be inserted by sliding in the width direction of the main frame 19a, and the decorative plate 18 is fitted into the groove 26 of the main frame 19a. The decorative plate 18 can be fixed (fixing the decorative plate 18 in the insertion direction can be fixed by general bonding), and a fixing shaft is not required, so that the configuration is suitable for reducing the number of parts. It is.

  Here, when the surface of the decorative board 18 is worn due to friction caused by the user's walking, it is generally required to replace the getting-on / off floors 8 and 9 in order to prevent the user from falling due to a decrease in frictional resistance. Although it is the actual condition, since only the decorative board 18 can be slid and replaced by this configuration, it is possible to reduce the material cost for replacement and the lead time for manufacturing and replacement. In addition, when storing alternatives for replacement in advance, since storage was conventionally performed for each boarding / exiting floor, a large storage space was required. However, with the configuration of the present embodiment, only the decorative board 18 is stored. This is an effective means for saving storage space.

  Also, in the configuration of the main frame body 19a in the present embodiment, since it is formed of a continuous body having substantially the same cross-sectional shape, the width of the main frame body 19a can be obtained by cutting it according to the required length. The dimension L can be easily changed. Therefore, it is possible to provide the escalator landing floors 8 and 9 having a wide variety of widths.

  Next, FIG. 10 illustrating the third embodiment of the present invention (FIG. 10 is a view of the getting-on / off floor as seen from the side as in FIG. 1, and the horizontal direction of the upper surface of the decorative board 18 on the paper is the user. Is a sectional view showing a state in which the getting-on / off floors 8 and 9 are incorporated in the escalator 1, and when the several getting-on / off floors 8 and 9 are incorporated, the uneven portions provided in the main frame 19 b By engaging the main frame bodies 19b before and after 27, 28, it is possible to bear the load from the user with the main frame bodies 19b, and to reduce the flexure of the entire landing floors 8, 9 It is. In other words, the main frame body 19b has the convex portion 27 at one end portion in the front and rear direction of the user traveling direction, the concave portion 28 at the other end portion, and the convex portion 27 or the concave portion 28 is adjacent to the adjacent main portion. It connects with the recessed part 27 or the convex part 28 of the frame 19b. Here, the dimension in the width direction of the concavo-convex portions 27 and 28 may be the entire width direction of the main frame body 19b or a part thereof. Furthermore, in this embodiment (the same applies to FIGS. 11 and 12), both end sides of the main frame 19b of the passenger floors 8 and 9 in the user traveling direction are supported by supports integrally formed with the frame 5. Therefore, when two main frame bodies 19b are provided in the user traveling direction in the illustrated example of FIG. 10, if only the above-mentioned support bodies on both ends are provided, the user is located at the center portion in the width direction of the main frame body 19b. Although there may be a possibility of bending with a load, the above-described deflection can be prevented by providing the above-described uneven portions 27 and 28.

  Next, FIG. 11 illustrating the fourth embodiment of the present invention shows a configuration of another main frame body 19c with respect to FIG. 10, and the main frame body 19c has similar uneven portions 29 and 30. FIG. However, the concave portion 30 of the adjacent main frame 19c is placed on the convex portion 29. Unlike the concavo-convex portions 27 and 28 in FIG. 10, the right main frame 19 c is supported by the convex portion of the left main frame in FIG. 11, and the boarding floors 8 and 9 as a whole are also configured in the configuration shown in FIG. 11. This is sufficiently effective in reducing the bending of the material.

  Next, FIG. 12 illustrating the fifth embodiment of the present invention shows an installation area of the main frame body 19d (that is, the lower surface of the main frame body 19d when the getting-on / off floors 8 and 9 are incorporated in the escalator 1). In order to minimize the area where the left and right ends in the user traveling direction are supported by the support described above, an example is shown in which convex portions 31 are provided at the front and rear end portions in the user traveling direction on the lower surface of the main frame 19d. In other words, with respect to the supports (supports fixed to the frame 5 and disposed along both ends in the width direction perpendicular to the user traveling direction) provided at the left and right ends in the user traveling direction. The left and right sides of the frame body 19d are not in contact with each other, but are provided with convex portions 31 only at the front and rear end portions thereof, and are supported on the support body only by the convex portions.

  According to the configuration shown in FIG. 12, due to manufacturing errors of the escalator 1 or the getting-on / off floors 8, 9, the surface of the getting-on / off floors 8, 9, that is, the seam 32 of the decorative board 18 or the boundary 33 with the building floor If the step difference is generated, the protrusion 31 provided below the main frame 19d is adjusted by grinding with a file or the like to eliminate the step difference at the joint 32 of the decorative board 18 or the boundary 33 with the building floor. Is. This configuration is also effective for the above-described FIG. 10 and FIG. 11, and can be easily stepped by forming the lower surfaces of the front and rear end portions in the user traveling direction as the convex portions 31 rather than the configuration in which the entire main frame is installed. It is an effective means for enabling adjustment.

  As described above, in the above-described embodiment, the escalator has been described as an example. However, in other passenger conveyors such as a moving sidewalk, it is common to use a similar getting-on / off floor, and the main frame is substantially omitted. Since it is formed of a continuous body with the same cross-sectional shape, the width of the main frame can be easily changed by cutting it according to the required length, making it easy for wide walkways. Applicable. Thus, the present invention can be used for passenger conveyors such as escalators and moving walkways.
