[Modes for carrying out the invention] 【0009】 The embodiments will be described below with reference to the figures. In the following, the same or corresponding parts will be denoted by the same reference numerals, and redundant explanations will not be repeated. 【0010】 (Embodiment 1) The configuration of the escalator 100 according to Embodiment 1 will be described with reference to Figures 1 to 3. Figure 1 is a schematic side view showing the configuration of the escalator 100 according to Embodiment 1 from the side. Figure 2 is a schematic top view showing the configuration of the floor plate 2 and step 8 of the escalator 100 according to Embodiment 1 from above. Figure 3 is a schematic cross-sectional view showing the configuration of the floor plate 2 and step 8 of the escalator 100 according to Embodiment 1 from the side. 【0011】 Referring to Figure 1, the escalator 100 comprises a truss 1, a floor plate 2, an upper sprocket 3, a lower sprocket 4, a step chain 5, a drive unit 6, a control unit 7, a step 8, a railing 9, a movable handrail 10, and a machine room 11. 【0012】 Truss 1 houses floor slabs 2, upper sprockets 3, lower sprockets 4, step chains 5, drive unit 6, and control unit 7. Floor slabs 2 are installed in the upper and lower sections of truss 1, respectively. Upper sprockets 3 are installed in the upper section of truss 1. Lower sprockets 4 are installed in the lower section of truss 1. Step chains 5 are wrapped around upper sprockets 3 and lower sprockets 4. When drive unit 6 drives upper sprockets 3, step chains 5 wrapped around upper sprockets 3 and lower sprockets 4 are driven. When drive unit 6 drives step chains 5, steps 8 connected to step chains 5 move in a circular motion between the upper and lower sections. Control unit 7 is configured to control drive unit 6 and the like. 【0013】 A railing 9 is positioned above the truss 1. A movable handrail 10 is attached to the railing 9. The movable handrail 10 moves in a circular motion between the upper and lower floors. The movable handrail 10 moves in conjunction with the step 8. Machine rooms 11 are installed in the upper and lower parts of the truss 1, respectively. 【0014】 Referring to Figures 2 and 3, the configuration of the floor plate 2, step 8, plate 30, and switch 40 of the escalator 100 according to Embodiment 1 will be described. 【0015】 Step 8 is configured to move sequentially under the floorboard 2. Multiple grooves R are provided in step 8. The surface of step 8 is provided with irregularities due to the multiple grooves R. Each of the multiple combs C of the floorboard 2 is inserted into each of the multiple grooves R. 【0016】 The bed board 2 has a plurality of combs C. Each of the plurality of combs C is configured to mesh with each of the plurality of grooves R respectively. The bed board 2 includes a rubber part 21, a rubber plate 22, and screws 23. A plurality of combs C are provided on the rubber part 21. The rubber part 21 is attached to the rubber plate 22. The screws 23 fix the rubber part 21 and the rubber plate 22. 【0017】 The escalator 100 includes a plate 30. The plate 30 is attached to at least one of the plurality of combs C. The plate 30 is disposed between at least one of the bottoms B of the plurality of grooves R and at least one of the plurality of combs C. The plate 30 is configured to be rotatable along the moving direction of step 8. 【0018】 The plate 30 is configured to rotate about an axis connected to the comb C. The plate 30 is configured to open by rotating forward in the moving direction of step 8. The plate 30 is configured to close by extending toward the bottom B of the groove R of step 8. The plate 30 is configured to close when the plate 30 rotates backward in the moving direction of step 8 from the open state where the plate 30 rotates forward in the moving direction of step 8. The plate 30 is biased to close by a spring 31. When foreign objects such as dust accumulate in front of the plate 30 and the force pushing the plate 30 exceeds the biasing force of the spring 31 when the plate 30 is pushed by the foreign objects such as dust, the plate 30 opens, and the foreign objects such as dust pass through the plate 30 and flow to the rear of the plate 30. The foreign objects such as dust that flow to the rear of the plate 30 flow into the machine room 11. 【0019】 The escalator 100 includes a switch 40. The switch 40 is configured to detect the state in which the plate 30 is open. In the present embodiment, the switch 40 is a contact switch 41. The contact switch 41 is configured to detect the state in which the plate 30 is open by contacting the plate 30 when the plate 30 is opened. When the plate 30 is opened, the contact switch 41 is pushed by the plate 30, and thus the contact switch 41 operates. When the contact switch 41 operates for a certain period of time (for example, 10 seconds), the control device 7 stops the escalator 100. 【0020】 Next, the operation and effect of the escalator 100 according to Embodiment 1 will be described. According to the escalator 100 according to Embodiment 1, the plate 30 is disposed between at least one of the bottoms B of the plurality of grooves R and at least one of the plurality of scoops C, and is configured to be rotatable along the moving direction in Step 8. Therefore, since the plate 30 fills the gap between the step 8 and the scoop C, it is possible to prevent foreign matters such as dust from being caught in the gap between the step 8 and the scoop C. Further, when a certain amount of foreign matters such as dust accumulates near the boarding and alighting openings of the step 8, the plate 30 can be opened to discard the foreign matters such as dust. Also by this, it is possible to prevent foreign matters such as dust from being caught in the gap between the step 8 and the scoop C. 【0021】 According to the escalator 100 according to Embodiment 1, the switch 40 is configured to detect the state in which the plate 30 is open. Therefore, the state in which the plate 30 is open can be detected by the switch 40. 【0022】 According to the escalator 100 of Embodiment 1, the contact switch 41 is configured to detect the open state of the plate 30 by making contact with the plate 30 when the plate 30 opens. Therefore, when the plate 30 opens, the contact switch 41 can detect the open state of the plate 30 by making contact with the plate 30. Consequently, the contact switch 41 can be operated by making contact with the plate 30. Furthermore, if the contact switch 41 is operating for a certain period of time, the escalator 100 can be stopped. 【0023】 (Embodiment 2) The escalator 100 according to Embodiment 2 has the same configuration and effects as the escalator 100 according to Embodiment 1, unless otherwise specified. 【0024】 Referring to Figure 4, the configuration of the floor plate 2, step 8, plate 30, and switch 40 of the escalator 100 according to Embodiment 2 will be described. Figure 4 is a schematic cross-sectional view showing the configuration of the floor plate 2 and step 8 of the escalator 100 according to Embodiment 2 from the side. 【0025】 In the escalator 100 according to Embodiment 2, the switch 40 is a pressure switch 42. The pressure switch 42 is configured to detect when the plate 30 is pressed, causing the plate 30 to open. The pressure sensor for detecting the pressure of the pressure switch 42 is installed on the plate 30. 【0026】 In this embodiment, the pressure switch 42 is configured to detect the pressure applied to at least one of the multiple combs C. The pressure sensor for the pressure switch 42 may be installed on at least one of the multiple combs C, in addition to the plate 30. The pressure switch 42 is mounted on the comb plate 22. The pressure switch 42 is positioned between the tip of the comb plate 22 and the screw 23. 【0027】 Furthermore, in this embodiment, the pressure switch 42 is configured to detect the pressure applied to each of the multiple combs C. In addition to the plate 30, the pressure sensor for detecting the pressure of the pressure switch 42 may also be installed on each of the multiple combs C. 【0028】 When plate 30 is pressed by foreign matter such as dirt, the pressure switch 42 is activated. When the pressure switch 42 is activated, the electromagnet on plate 30 is activated, causing plate 30 to open and the foreign matter such as dirt to flow to the back of plate 30. The foreign matter such as dirt that has flowed to the back of plate 30 flows to the machine room 11. When the foreign matter such as dirt has flowed to the back of plate 30, the operation of the electromagnet on plate 30 is deactivated, causing plate 30 to close. If the pressure switch 42 is operating for a certain period of time (for example, 10 seconds), the escalator 100 stops. The escalator 100 may also stop when a pressure exceeding a certain threshold is applied to the pressure switch 42. When the escalator 100 stops, the reason for the stop may be displayed on the control device (control panel) 7. Also, when the escalator 100 stops, a malfunction C may be displayed on the control device (control panel) 7. 【0029】 Next, the effects and benefits of the escalator 100 according to Embodiment 2 will be described. According to the escalator 100 of Embodiment 2, the pressure switch 42 is configured to detect when the plate 30 is pressed and opens, thereby detecting that the plate 30 is open. Therefore, the pressure switch 42 can be activated when the plate 30 is pressed. Consequently, if the pressure switch 42 is operating for a certain period of time, the escalator 100 can be stopped. 【0030】 According to the escalator 100 of Embodiment 2, the pressure switch 42 is configured to detect the pressure applied to at least one of the multiple combs C. Therefore, if a large foreign object hits at least one of the multiple combs C, the pressure switch 42 can detect the pressure. Consequently, if a large pressure is applied to at least one of the multiple combs C, the pressure switch 42 can detect the pressure and immediately stop the escalator 100. The pressure switch 42 is attached to the comb plate 22, and is positioned between the tip of the comb plate 22 and the screw 23. Therefore, the installation of the pressure switch 42 is easy. 【0031】 According to the escalator 100 of Embodiment 2, the pressure switch 42 is configured to detect the pressure applied to each of the multiple combs C. Therefore, the pressure switch 42 can detect which of the multiple combs C has pressure applied to it. Thus, it can recognize which of the multiple combs C has malfunctioned. 【0032】 (Embodiment 3) The escalator 100 according to Embodiment 3 has the same configuration and effects as the escalator 100 according to Embodiment 1, unless otherwise specified. 【0033】 Referring to Figure 5, the configuration of the floor plate 2 of the escalator 100 according to Embodiment 3 will be described. Figure 5 is a partial plan view showing the configuration of the floor plate 2 of the escalator 100 according to Embodiment 3 from above. 【0034】 In the escalator 100 according to Embodiment 3, the comb portion 21 is provided with through holes H extending to the left and right. The screws 23 are fixed to the comb plate 22 while inserted into the through holes H. The comb portion 21 is attached to the comb plate 22 so as to be slidable from left to right. 【0035】 Referring to Figure 6, the configuration of the floor plate 2 of the escalator 100 according to Embodiment 3 will be described. Figure 6 is a schematic cross-sectional view from the front of the movement method showing the state in which each of the multiple combs C of the escalator 100 according to Embodiment 3 is engaged with each of the multiple grooves R. 【0036】 In the floor plate 2 of the escalator 100 according to Embodiment 3, the comb portion 21 can be slid left and right while the screw 23 is inserted into the through hole H. This allows multiple combs C to be slid left and right. In Figure 6, the state after multiple combs C have been slid left and right is shown by a solid line, and the state before multiple combs C have been slid left and right is shown by a dashed line. 【0037】 Next, the effects and benefits of the escalator 100 according to Embodiment 3 will be described. In the escalator 100 according to Embodiment 3, the screw 23 is fixed to the comb plate 22 while inserted into the through hole H that extends to the left and right. With each of the multiple combs C engaged with each of the multiple grooves R, the distance between each comb C and the side of each groove R is not constant because it is shifted left and right depending on the position of step 8. With the screw 23 inserted into the through hole H, each comb C can be slid left and right by sliding the comb portion 21 from side to side. This makes it possible to suppress malfunctions caused by contact between each comb C and the side of each groove R. 【0038】 The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of this disclosure is indicated by the claims rather than the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended. 【0039】 The various forms of this disclosure are summarized below as an appendix.
