[Figure 10] This figure shows an alternative configuration of the boundary between the upper surface and mounting portion of the inner deck in Modification Example 2. [Modes for carrying out the invention]
[0008] —First Embodiment— A first embodiment of the passenger conveyor will be described below with reference to Figures 1 to 8.
[0009] Figure 1 is a schematic diagram of the passenger conveyor 1. In this embodiment, mutually orthogonal XYZ axes are defined to clearly show the correlation between the drawings. In Figure 1, the upper part of the diagram is the positive side of the Z axis, the right side of the diagram is the positive side of the Y axis, and the front of the diagram is the positive side of the X axis. The passenger conveyor 1 is a conveyor, also known as an escalator, installed on the floors of the upper and lower floors of a building structure for people to board and alight. The passenger conveyor 1 comprises a frame 2 installed on the building structure, a plurality of steps 3, a drive mechanism 4 that drives the steps 3, a railing section 5, a deck 6 that supports the railing section 5, a lower boarding / alighting floor 71, and an upper boarding / alighting floor 72.
[0010] Frame 2 is installed spanning the lower boarding / alighting platform 71 and the upper boarding / alighting platform 72. Frame 2 includes a straight section 21, which is a straight line section in the height direction, i.e., where the Z-axis coordinate value changes; a lower transition section 22 from the lower boarding / alighting platform 71 to the straight section 21; and an upper transition section 23 from the straight section 21 to the upper boarding / alighting platform 72. Hereafter, the direction extending from the lower boarding / alighting platform 71 to the upper boarding / alighting platform 72 in Frame 2 will be referred to as the longitudinal direction of Frame 2. The width direction of Frame 2 is the X-axis direction.
[0011] Step 3 moves along a guide rail (not shown) provided on the frame 2, either from the lower boarding platform 71 to the upper boarding platform 72, or from the upper boarding platform 72 to the lower boarding platform 71. The steps 3 are connected in an endless manner and move in a cyclic manner by the drive mechanism 4.
[0012] A pair of railing sections 5 are provided so as to sandwich the steps 3 from the X-axis direction. However, in Figure 1, only one railing section 5 is shown for drawing purposes. Each railing section 5 comprises a railing panel 51 and a movable handrail 52 arranged around the railing panel 51. The movable handrail 52 moves in the same direction as the steps 3, synchronized with the movement of the steps 3. The deck 6 is provided along the longitudinal direction of the frame 2, at both ends of the frame 2 in the width direction. The deck 6 covers the entire straight section 21 of the frame 2, a part of the lower transition section 22, and a part of the upper transition section 23.
[0013] Figure 2 is a perspective view of the lower transition section 22 in the passenger conveyor 1. In Figure 2, the railing part 5 and the deck 6 arranged on the minus side of the X-axis of the step 3 are shown. The deck 6 includes an inner deck 61, an outer deck 62, and a skirt guard 63. The deck 6 is arranged below the railing part 5, that is, on the minus side of the Z-axis, to support the railing part 5, and sandwiches the railing part 5 from both sides of the X-axis. The railing panel 51 may be transparent, but in this figure, the railing panel 51 is opaque and does not transmit the objects behind it. Therefore, the outer deck 62 is not shown in Figure 2.
[0014] The inner deck 61 is arranged near the step 3 at the lower part of the railing panel 51, and the outer deck 62 is arranged on the opposite side. The inner deck 61 has a curved shape as shown in Figure 2. The skirt guard 63 is arranged along the vertical direction, that is, the Z-axis direction, on the side of the step 3.
[0015] Figure 3 is a cross-sectional view of the inner deck 61. However, the circled part in the upper right of Figure 3 is an exploded view of the mall 64 part described later, and the circled part in the lower right is a schematic configuration diagram of the inner deck 61. In Figure 3, the railing panel 51 adjacent to the inner deck 61 and the outer deck 62 adjacent to the minus side of the X-axis are also shown.
[0016] The inner deck 61 has a substantially L-shaped cross-section as shown in the circled part in the lower right of Figure 3. Hereinafter, the long side part is called the upper surface part 611, and the short side part is called the mounting part 612. The end part on the minus side of the X-axis of the upper surface part 611 is fixed by the fixture 511 attached to the railing panel 51. As shown in the circled part in the upper right of Figure 3, the mounting part 612 is fixed to the skirt guard 63 using screws 65 together with the mall 64. As shown by the dashed-line circle, that is, part A, in the circled part in the upper right of Figure 3, the mall 64 not only covers the mounting part 612 but also covers the region up to a predetermined distance from the end part on the plus side of the X-axis of the upper surface part 611.
[0017] Figure 4 is a diagram showing the shape of the inner deck 61 before assembly. Since this figure shows the shape before assembly, the XYZ axes are not illustrated. The inner deck 61 is formed by cutting out a fan shape along the R shape of the passenger conveyor 1 where the plate material will ultimately be arranged, forming holes through which the screws 65 pass, and only bending the mounting portion 612. The cutting out from the plate material can be realized, for example, by laser processing.
[0018] Figure 5 is a diagram showing the arrangement of the inner deck 61. As shown by the arrow M1, the inner deck 61 is moved and arranged to fit the bent shape.
[0019] Figure 6 is a diagram showing the arrangement of the molding 64. As shown by the arrow M2, the molding 64 is arranged to cover the mounting portion 612 of the inner deck 61. Then, as shown in Figure 3, the molding 64 and the inner deck 61 are fixed to the skirt guard 63 using the screws 65.
[0020] Figure 7 is a diagram explaining the range of the inner deck 61 covered by the molding 64. Note that Figure 7 is for conceptual explanation, and the shape of the inner deck 61 shown is not accurate. The upper part of Figure 7 shows the inner deck 61 not covered by the molding 64, and the lower part of Figure 7 shows the inner deck 61 covered by the molding 64.
[0021] The inner deck 61 shown in Figure 7 has an upper surface portion 611 on the upper side and a mounting portion 612 on the lower side. Exactly, each region where the plate material exists on the lower side of the inner deck 61 shown in the figure is the mounting portion 612. The upper surface portion 611 is connected to each mounting portion 612. In the inner deck 61, each mounting portion 612 is not directly connected, but is connected to other mounting portions 612 only through the upper surface portion 611. When not covered by the molding 64, the end portion of the lower part shown in the figure has irregularities due to the presence or absence of the mounting portion 612, and intermittent gaps occur.
[0022] As shown in the upper right of Figure 3, the molding 64 also covers a portion of the upper surface portion 611 on the mounting portion 612 side. This is clearly illustrated in the lower part of Figure 7, where the hatched area 64C is the area covered by the molding 64. In other words, the position of the end remains constant regardless of the presence or absence of the mounting portion 612, and the gap is concealed.
[0023] (Comparative example) Figure 8 shows a comparative inner deck 61Z, which is different from the inner deck 61 described above. The comparative inner deck 61Z has a cross-sectional shape that resembles a square bracket. The cross-sectional shape of the comparative inner deck 61Z can also be described as a rectangle with one side removed. The comparative inner deck 61Z has an upper surface portion 611 and a comparative mounting portion 612Z, similar to the inner deck 61. Each comparative mounting portion 612Z is connected without going through the upper surface portion 611.
[0024] The manufacturing method for the comparative inner deck 61Z is as follows: First, the sheet metal is bent to form the cross-sectional shape. Next, while pressing it against a mold, both ends are pulled to form the bent shape. The manufacturing of this comparative inner deck 61Z has the following three problems, for example: Firstly, it requires specialized equipment and mold maintenance for tension bending. Secondly, it requires fine-tuning of the molding conditions for each material, and know-how is needed for production. Thirdly, because force is applied during molding to bend the material, there is an impact on the design surface, such as whitening of the material.
[0025] In contrast, the inner deck 61 in this embodiment can be manufactured using general-purpose machinery such as laser processing machines and presses. Furthermore, the area to be bent is minimal, resulting in little impact on the surface design. In addition, since no force is applied to bend the material, whitening of the material is less likely to occur.
[0026] According to the first embodiment described above, the following effects and advantages can be obtained. (1) The passenger conveyor 1 comprises a plurality of endlessly connected steps 3 that move in a circulating manner, a skirt guard 63 positioned vertically along the side of the steps 3, a railing 5, a deck 6 that supports the railing 5, and an inner deck 61 that covers the upper part of the deck 6 on the step 3 side. The inner deck 61 comprises an upper surface 611 that covers the upper part of the deck 6, and a plurality of mounting parts 612 that are substantially parallel to the side of the deck 6, formed integrally with the upper surface 611, and that fix the inner deck 61 to the skirt guard 63. Each of the mounting parts 612 on the inner deck 61 is connected to the other mounting parts 612 only via the upper surface 611. Therefore, the inner deck 61 of the passenger conveyor 1 is easier to manufacture than the comparative inner deck 61Z.
[0027] (2) The inner deck 61 has a roughly L-shaped cross-section, with the upper surface portion 611 as the first side and the mounting portion 612 as the second side. The inner deck 61 is formed by bending the mounting portion 612 formed at the end of a plate material processed to an appropriate shape, so it does not need to have a cross-sectional shape like the comparative inner deck 61Z, making it easy to manufacture. The comparative inner deck 61Z is formed into a bent shape by pulling both ends of the plate material while pressing it against a mold, so it was necessary to have a cross-sectional shape like a square bracket. However, since the inner deck 61 in this embodiment is manufactured by a different method, it can have a roughly L-shaped cross-section.
[0028] (3) A molding 64 is provided to cover the mounting portion 612. Therefore, the position of the end remains constant regardless of whether the mounting portion 612 is present or not, and the gap in the area where the mounting portion 612 is not present is concealed.
[0029] (Variation 1) Figure 9 shows the molding 64A in modified example 1. The molding 64A includes a molding fixing portion 641 and a molding covering portion 642. The molding fixing portion 641 is fixed to the skirt guard 63 together with the inner deck 61. The molding covering portion 642 is sandwiched between the molding fixing portion 641 and the inner deck 61 and covers a part of the upper part of the inner deck 61 along its longitudinal direction. By making the molding covering portion 642 a separate component from the molding fixing portion 641, it becomes easier to process the tip of the molding covering portion 642, that is, the end on the negative X-axis side in Figure 9, so that it can be closely fitted to the surface of the upper surface portion 611.
[0030] According to this modified example 1, the following effects can be obtained. (4) The molding 64 includes a molding fixing portion 641 which is fixed to the skirt guard 63 together with the inner deck 61, and a molding covering portion 642 which is sandwiched between the molding fixing portion 641 and the inner deck 61 and covers a part of the mounting portion 612 side of the upper surface portion 611 along the longitudinal direction of the inner deck 61.
[0031] (Modification 2) Figure 10 shows an alternative configuration of the boundary 614 between the upper surface 611 of the inner deck 61 and the mounting portion 612. In the embodiment described above, the length of the boundary 614 of each mounting portion 612 was the same as the longitudinal length of the inner deck 61 at the mounting portion 612. However, by providing a notch, the length of the boundary 614 of the mounting portion 612 may be made shorter than the longitudinal length of the inner deck 61 at the mounting portion 612.
[0032] As shown in boundary 614A, the length of the boundary 614 of the mounting portion 612 may be made shorter than the longitudinal length of the inner deck 61 in the mounting portion 612 by providing notches at both ends of the boundary portion. Alternatively, as shown in boundary 614B, the length of the boundary 614 of the mounting portion 612 may be made shorter than the longitudinal length of the inner deck 61 in the mounting portion 612 by providing a notch in the longitudinal center of the inner deck 61 in the boundary portion.
[0033] According to this modified example 2, the following effects can be obtained. (5) A notch is provided at the boundary between the mounting portion 612 and the upper portion 611 to reduce the contact area between the mounting portion 612 and the upper portion 611. Therefore, by reducing the straight portion at the boundary between the upper portion 611 and the mounting portion 612 of the inner deck 61 which needs to be bent, the occurrence of distortion can be suppressed.
[0034] (Variation 3) The cross-sectional shape of the inner deck 61 is not limited to an L-shape. For example, it may have any cross-sectional shape to match the shape of the fastener 511 attached to the railing panel 51. Also, similar to the comparative inner deck 61Z, the cross-section may be in the shape of a square bracket.
[0035] (Modification 4) The inner deck 61 described above may be used only in a portion of the deck 6. The inner deck 61 is part of the deck 6 shown in Figure 1, and the deck 6 extends across the straight section 21, the lower transition section 22, and the upper transition section 23 of the frame 2. The inner deck 61 described above is useful in non-straight sections, and in particular, the straight section 21 may have a different structure from the inner deck 61. Also, the mall 64 shown in Figure 3 is not a mandatory configuration, and the passenger conveyor 1 does not need to have a mall 64.
[0036] The embodiments and modifications described above may be combined in any way. Although various embodiments and modifications have been described above, the present invention is not limited to these. Other embodiments that can be conceivable within the scope of the technical idea of the present invention are also included within the scope of the present invention. [Explanation of Symbols]
