DETAILED DESCRIPTION

[0023] Hereinafter, embodiments will be described with reference to the drawings.

[0024] Implementation Method 1

[0025] Figure 1 This is a plan view showing the entrance and exit of an escalator according to Embodiment 1. A plurality of steps 1 are connected in a ring shape. Furthermore, the plurality of steps 1 are supported by a main frame (not shown). The main frame is installed between the upper and lower floors.

[0026] Each step 1 moves in a circular motion along a circulation path (not shown). The circulation path has an outward path, a return path, an upper reversing portion, and a lower reversing portion. A plurality of grooves 1a parallel to the direction of travel are provided on the upper surface of each step 1. The upper surface of each step 1 is the upper surface when the step 1 is on the outward path, that is, the surface for passengers to board. Figure 1 In the embodiment, the moving direction of each step 1 is left or right.

[0027] A pair of handrails 2 are provided on the main frame. A ring-shaped moving handrail 3 is provided on each handrail 2. Each moving handrail 3 moves synchronously with the plurality of steps 1.

[0028] A floor 4 is provided at the entrance. A comb device 5 is provided between the floor 4 of the entrance and the steps 1. The comb device 5 includes a comb plate 6 and a plurality of comb members 7.

[0029] The comb plate 6 is arranged over the entire width direction of the boarding and landing entrance. The width direction of the boarding and landing entrance is a direction perpendicular to the direction of travel of each step 1 at the boarding and landing entrance and horizontal to the direction of travel of each step 1 at the boarding and landing entrance. Figure 1 up and down directions.

[0030] Each comb-tooth member 7 is fixed to the comb-tooth plate 6 using a plurality of fixing tools (not shown). As each fixing tool, screws are used, for example. In addition, the plurality of comb-tooth members 7 are arranged in a row along the width direction of the boarding and alighting entrance.

[0031] Each comb-tooth member 7 is made of resin or metal. For example, fiber-reinforced resin is used as the resin. For example, aluminum or an aluminum alloy is used as the metal. The comb-tooth plate 6 is made of a metal stronger than the material of each comb-tooth member 7, such as steel.

[0032] Figure 2 It is along Figure 1 Cross-sectional view along line II-II. Figure 3 It is enlarged to show Figure 1 A top view of one of the plurality of comb teeth parts 7 and a portion of the comb plate 6.

[0033] Each comb member 7 includes a fixing portion 7a and a plurality of comb teeth 7b. The fixing portion 7a is superimposed on and fixed to the comb plate 6. The plurality of comb teeth 7b protrude from the fixing portion 7a in parallel with each other along the direction of travel of the step 1.

[0034] Each comb tooth 7b has a base 7c, an insertion portion 7d, and a connecting portion 7e. The base 7c is the portion adjacent to the fixing portion 7a and not inserted into the groove 1a. That is, when the comb tooth member 7 is installed in the escalator, the base 7c is located above the upper surface of the step 1 at the entrance.

[0035] The insertion portion 7d is the front end portion of the comb teeth 7b and is inserted into the groove 1a. The connection portion 7e is the middle portion of the comb teeth 7b and is the portion connecting the base portion 7c and the insertion portion 7d.

[0036] Each base portion 7c is located on the comb plate 6. The bottom surface 7f of each base portion 7c is in contact with the upper surface of the comb plate 6. In addition, the bottom surface 7f of each base portion 7c is neither bonded nor fixed to the upper surface of the comb plate 6.

[0037] The bottom surface 7f of each base portion 7c is provided with a notch 11. Each notch 11 is provided along the width direction of each comb tooth 7b. The width direction of each comb tooth 7b is parallel to the width direction of the boarding and alighting entrance. Each notch 11 serves as the starting point for the breakage of each comb tooth 7b.

[0038] Each notch 11 is positioned away from the boundary between the fixed portion 7a and the comb teeth 7b. Furthermore, each notch 11 is also positioned away from the front end face 6c of the comb plate 6. The front end face 6c is the end face of the comb plate 6, i.e., the end face on the side of the boundary between the comb device 5 of the entrance and the steps 1.

[0039] Figure 2 The cross-sectional shape of the incision 11 in the comb plate 6 is a triangle, but the cross-sectional shape of each incision 11 is not limited to a triangle. In addition, each incision 11 can be formed by molding, and can also be formed by cutting after comb plate 6 is molded.

[0040] In this comb tooth device 5, a notch 11 is provided on the bottom surface 7f of each base portion 7c. Furthermore, each base portion 7c is not inserted into the groove 1a. Therefore, if the comb teeth 7b are damaged, for example, by colliding with a foreign object in the groove 1a and receiving a load from below, the comb teeth 7b are more likely to be damaged through the notch 11. This reduces the likelihood that a portion of the comb teeth 7b will remain in the groove 1a after damage, thus preventing damage to the steps 1 caused by deformation of the comb teeth 7b.

[0041] Furthermore, among the plurality of comb teeth 7 b , only the comb teeth 7 b subjected to the load from below are more likely to be damaged, and degradation of the function of the comb tooth member 7 as a whole can be minimized.

[0042] Furthermore, the bottom surface 7f of each base portion 7c is in contact with the comb-tooth plate 6. Therefore, damage to each comb tooth 7b due to a load from above can be suppressed.

[0043] Implementation Method 2

[0044] then, Figure 4 It is a plan view showing a part of the comb-tooth member 7 and the comb-tooth plate 6 in an enlarged manner according to the second embodiment. Figure 5 is to remove Figure 4 A top view of the comb tooth component 7 is shown.

[0045] The comb plate 6 of Embodiment 2 includes a comb plate main body 6a and a plurality of comb plate protrusions 6b. The fixing portion 7a overlaps with the comb plate main body 6a.

[0046] A plurality of comb plate protrusions 6b protrude from the comb plate main body 6a in parallel with each other along the traveling direction of the steps 1. The bottom surface 7f of each base portion 7c contacts the upper surface of the corresponding comb plate protrusion 6b.

[0047] The length of each comb plate protrusion 6b in a direction parallel to the direction of travel of the step 1 is the length not inserted into the groove 1a. In other words, when the comb plate 6 is installed in the escalator, each comb plate protrusion 6b is located above the upper surface of the step 1 at the entrance.

[0048] Apart from Figure 4 and Figure 5 Other than the illustrated configuration, the configuration of the comb device 5 and the configuration of the escalator are the same as those of the first embodiment.

[0049] According to such a comb device 5, the area of ​​the comb plate 6 visible between adjacent comb teeth 7b when viewed from directly above can be reduced or eliminated, thereby making the comb plate 6 less conspicuous.

[0050] Implementation 3

[0051] then, Figure 6 This is a cross-sectional view showing the key parts of the escalator according to the third embodiment, showing the Figure 1 The cross section of line II-II is equivalent to the cross section of Figure 7 It shows Figure 6 A top view of the key parts of the comb device 5.

[0052] A plurality of intermediate members 8 are provided between the comb plate 6 and the plurality of comb members 7. Each intermediate member 8 is made of a metal, such as steel, that is stronger than the material of the comb members 7. Furthermore, each intermediate member 8 is positioned entirely below the corresponding comb member 7. The front end surface 6c of the comb plate 6 is flat, and the comb plate 6 does not have a comb plate protrusion 6b.

[0053] Each intermediate member 8 includes an intervening portion 8a and a plurality of intermediate protruding portions 8b. The intervening portion 8a is interposed between the comb plate 6 and the fixing portion 7a.

[0054] Multiple intermediate protrusions 8b protrude parallel to each other from the interposed portion 8a along the direction of travel of the step 1. The bottom surface 7f of each base portion 7c contacts the upper surface of the corresponding intermediate protrusion 8b. Furthermore, the bottom surface 7f of each base portion 7c is neither bonded nor fixed to the upper surface of the intermediate protrusion 8b.

[0055] The length of each intermediate protrusion 8b in a direction parallel to the direction of travel of the step 1 is the length not inserted into the groove 1a. That is, when the intermediate member 8 is installed in the escalator, each intermediate protrusion 8b is located above the upper surface of the step 1 at the entrance.

[0056] Apart from Figure 6 and Figure 7 Other than the illustrated configuration, the configuration of the comb device 5 and the configuration of the escalator are the same as those of the first embodiment.

[0057] In such a comb device 5, a plurality of intermediate members 8 are provided between the comb plate 6 and the plurality of comb members 7. Furthermore, each intermediate member 8 is made of a material having a higher strength than that of the comb members 7. Furthermore, the bottom surface 7f of each base portion 7c contacts the upper surface of the corresponding intermediate protrusion 8b.

[0058] Therefore, similar to Embodiments 1 and 2, when a load is applied from below, only the comb teeth 7b subjected to the load are damaged, and when a load is applied from above, damage to the comb teeth 7b can be suppressed. Furthermore, the possibility of a portion of the comb teeth 7b remaining in the groove 1a after damage is reduced, thereby suppressing damage to the step 1 caused by deformation of the comb teeth 7b.

[0059] Furthermore, the combination of the plurality of comb-tooth members 7 and the plurality of intermediate members 8 can provide the same effects as those of the first and second embodiments, and thus can be easily applied to an existing escalator while retaining the existing comb-tooth plates 6 .

[0060] In Embodiment 3, each comb-tooth member 7 may also be bonded to the corresponding intermediate member 8. This allows each comb-tooth member 7 to be transported or attached to the comb-tooth plate 6 while being assembled with the corresponding intermediate member 8. In this case, the bonding strength is preferably such that, for example, if the comb teeth 7b collide with foreign matter in the groove 1a and become damaged, the comb teeth 7b can be easily peeled off from the intermediate protrusion 8b without affecting the intermediate protrusion 8b.

[0061] In Embodiment 3, the plurality of comb-tooth members 7 and the plurality of intermediate members 8 do not necessarily correspond one to one. For example, one intermediate member 8 may be provided between the comb-tooth plate 6 and two or more comb-tooth members 7 .

[0062] Furthermore, in the third embodiment, the plurality of intermediate protrusions 8b may not be provided on the intermediate member 8. That is, the intermediate member 8 may have a shape in which the intervening portion 8a extends to the boundary between the base portion 7c and the connecting portion 7e.

[0063] Implementation 4

[0064] then, Figure 8 1 is a plan view showing the main parts of the comb device 5 according to Embodiment 4. The comb member 7 according to Embodiment 4 includes a fixing portion 7a, a plurality of comb teeth 7b, and a plurality of ribs 7g. Each rib 7g connects the upper surfaces of adjacent base portions 7c.

[0065] The thickness of each rib 7g is smaller than that of the comb teeth 7b. Furthermore, the thickness of each rib 7g is set so that if a comb tooth 7b is damaged by a load from below, the two ribs 7g adjacent to the damaged comb tooth 7b are easily damaged. This prevents the load from being transmitted to the unloaded comb teeth 7b.

[0066] Apart from Figure 8 Other than the illustrated configuration, the configuration of the comb device 5 and the configuration of the escalator are the same as those of the third embodiment.

[0067] In such a comb device 5, since the rib 7g is provided between the upper surfaces of the adjacent bases 7c, the gap between the adjacent bases 7c can be made less noticeable, thereby improving the design. In addition, foreign matter can be prevented from being caught between the adjacent bases 7c.

[0068] In addition, in Embodiments 1 and 2, ribs 7g may be provided between the upper surfaces of adjacent base portions 7c.

[0069] Furthermore, in Embodiments 1 to 4, two or more cutouts 11 may be provided in each base portion 7 c.

[0070] In addition, in Embodiments 1 to 4, the number of comb-tooth members 7 is not particularly limited.

[0071] In addition, in Embodiments 1 to 4, the comb-tooth plate 6 may be divided into a plurality of parts in the width direction of the entrance.

[0072] Furthermore, the passenger conveyor is not limited to an escalator, and may be, for example, a moving walkway.
