Embodiment 1 FIG.
1 is a cross-sectional view showing an example of a man conveyor according to Embodiment 1 of the present invention. FIG. 1 shows an escalator as an example of a man conveyor. A concrete description of other examples of the man conveyor such as a moving sidewalk is omitted.

  The escalator truss 1 is stretched between the upper and lower floors. The truss 1 supports the weight of the escalator and the load. Escalator passengers take step 2 as they move between the upper and lower floors. Step 2 is coupled to the step chain 3. The step chain 3 is endless. By connecting a large number of steps 2 to the step chain 3, the steps 2 are arranged from the upper entrance 4 to the lower entrance 5 without any gaps.

  An upper machine room 6 is formed below the entrance / exit 4. The machine room 6 is a space formed at the upper end of the truss 1. In the machine room 6, for example, an electric motor 7, a speed reducer 8, and a control device 9 are installed. A sprocket 10 is provided on a shaft provided in the machine room 6. The step chain 3 is wound around the sprocket 10.

  A floor apparatus 11 is arranged at the entrance / exit 4. The floor apparatus 11 closes the upper part of the machine room 6. For this reason, the passenger of an escalator cannot see the inside of the machine room 6 during movement. The floor apparatus 11 is supported from below by the truss 1.

  A lower machine room 12 is formed below the entrance 5. The machine room 12 is a space formed at the lower end of the truss 1. For example, a tension device 13 is installed in the machine room 12. A sprocket 14 is provided on a shaft provided in the machine room 12. The step chain 3 is wound around the sprocket 14.

  A floor apparatus 15 is disposed at the entrance / exit 5. The floor device 15 closes the upper part of the machine room 12. For this reason, the passenger of an escalator cannot see the inside of the machine room 12 during movement. The floor device 15 is supported from below by the truss 1.

  FIG. 2 is a plan view showing the upper entrance / exit 4. FIG. 3 is a view showing a cross section taken along the line AA of FIG. FIG. 4 is a cross-sectional view showing the truss 1. FIG. 4 is a view corresponding to the CC cross section of FIG. 3.

  FIG. 4 mainly shows a portion of the truss 1 that is disposed below the entrance 4. As shown in FIGS. 3 and 4, the truss 1 includes, for example, four L angles 16 a to 16 d, a support 17, a support 18, a support bracket 19, a support bracket 20, a support angle 21, a joint member 22, and a joint member 23. Prepare.

  The L angles 16a to 16d are arranged at the four corners of the truss 1 in the cross section shown in FIG. The L angles 16a to 16d are arranged so that the length thereof coincides with the length of the man conveyor. The L angles 16a to 16d are arranged in parallel to each other.

  The L angle 16 a and the L angle 16 b are disposed at the lowermost portion of the truss 1. The L angle 16c is disposed above the L angle 16a. A plurality of support columns 17 are provided between the L angle 16a and the L angle 16c. A support bracket 19 is provided on the L angle 16c. The support bracket 19 is fixed to a downward surface of the L angle 16c, for example. A joint member 22 is provided at the L angle 16c. The joint member 22 is fixed to the upper surface of the L angle 16c, for example. The joint member 22 protrudes upward from the L angle 16c.

  The L angle 16d is disposed above the L angle 16b. The L angle 16d is disposed at the same height as the L angle 16c. A plurality of support columns 18 are provided between the L angle 16b and the L angle 16d. A support bracket 20 is provided on the L angle 16d. The support bracket 20 is fixed to the downward surface of the L angle 16d, for example. The support bracket 20 protrudes from the L angle 16d to the L angle 16c side. Further, the support bracket 19 protrudes from the L angle 16c to the L angle 16d side. A joint member 23 is provided at the L angle 16d. The joint member 23 is fixed to the upper surface of the L angle 16d, for example. The joint member 23 protrudes upward from the L angle 16d.

  The support angle 21 is fixed to the support bracket 19 and the support bracket 20. In the example shown in the present embodiment, bolts are welded to both ends of the support angle 21. A bolt welded to one end of the support angle 21 is fixed to the support bracket 19 using a nut. As a result, one end of the support angle 21 is supported by the L angle 16 c via the support bracket 19. A bolt welded to the other end of the support angle 21 is fixed to the support bracket 20 using a nut. As a result, the other end of the support angle 21 is supported by the L angle 16 d via the support bracket 20.

  A portion of the truss 1 disposed below the entrance / exit 5 is configured similarly to a portion disposed below the entrance / exit 4.

  FIG. 5 is a view showing a BB cross section of FIG. 2. FIG. 5 shows a portion of the floor device 11 adjacent to the L angle 16c. The portion adjacent to the L angle 16d in the floor apparatus 11 is configured in the same manner as the portion adjacent to the L angle 16c. The configuration of the floor device 15 is the same as the configuration of the floor device 11. The floor device 11 includes a floor plate 24, a stopper 25, and a guide plate 26, for example.

  The floor plate 24 forms the floor surface of the entrance / exit 4 on the upper surface. That is, the passenger of the escalator steps on the floor plate 24 when passing through the entrance / exit 4. The floor plate 24 includes a reinforcing member 27, for example. The floor plate 24 is placed on the support angle 21 of the truss 1. By placing the floor plate 24 on the support angle 21, the floor apparatus 11 is supported by the truss 1.

  The stopper 25 is a member for preventing the floor plate 24 from being lifted. As shown by a broken line in FIG. 5, the floor plate 24 is prevented from being lifted by the stopper 25 being hooked on the hooked portion. The covered portion forms a part of the truss 1, for example. In the example shown in FIG. 5, the hooked portion is a part of the L angle 16c.

  The stopper 25 is disposed below the floor plate 24. The stopper 25 is adjacent to the hooked portion when the floor plate 24 is placed on the support angle 21. The stopper 25 is displaced so as to approach and separate from the covered portion. FIG. 5 shows an example in which the stopper 25 is provided on the floor plate 24 via the shaft 28. FIG. 6 is a diagram showing a DD cross section of FIG. 5. FIG. 6 shows an example in which the floor apparatus 11 includes two stoppers 25. In FIG. 6, the description of the guide plate 26 and the reinforcing member 27 is omitted.

  The guide plate 26 is a member for displacing the stopper 25 so that the stopper 25 approaches the hooked portion. For example, the guide plate 26 displaces the stopper 25 by applying the wind received on the lower surface to the stopper 25 from the opposite side of the hooked portion.

  The guide plate 26 is disposed below the floor plate 24. For example, the guide plate 26 is provided on the reinforcing member 27. FIG. 5 shows an example in which the lower surface of the guide plate 26 is flat. The upper surface of the floor plate 24 is horizontally arranged to form the floor surface of the entrance / exit 4. The lower surface of the guide plate 26 is disposed obliquely with respect to the upper surface of the floor plate 24. For example, the guide plate 26 is arranged such that the height of the lower surface becomes higher as it approaches the stopper 25. The stopper 25 is disposed between the hooked portion and the portion of the guide plate 26 having the lowest bottom surface.

  For example, when a man conveyor is installed at a station, wind enters the truss 1 when the train passes. An arrow E shown in FIG. 5 indicates a wind traveling upward in the truss 1. The wind traveling upward toward the floor plate 24 changes its direction toward the stopper 25 by hitting the lower surface of the guide plate 26. In the example shown in FIG. 5, the wind hitting the lower surface of the guide plate 26 travels to the left. The wind whose direction is changed by the guide plate 26 strikes the back surface 25 a of the stopper 25. Accordingly, the stopper 25 is displaced so as to approach the L angle 16c, that is, so as to approach the hooked portion. When the stopper 25 approaches the hooked portion, the hook-shaped portion at the tip is arranged immediately below the hooked portion as shown by a broken line in FIG. Since the stopper 25 is hooked on the hooked portion, the floor plate 24 can be prevented from being lifted.

  If no upward wind is generated in the truss 1, the hook-shaped portion formed at the tip of the stopper 25 is not disposed directly under the hooked portion. The stopper 25 is arranged vertically downward from the floor plate 24 as shown by a solid line in FIG. For this reason, for example, even if the maintenance staff of the man conveyor removes the floor apparatus 11 in order to perform maintenance work, the stopper 25 does not contact the hooked portion. Maintenance personnel can easily remove the floor apparatus 11.

  In the example shown in the present embodiment, the floor plate 24 can be prevented from being lifted even when another fluid enters the truss 1. For example, when a flood occurs, water enters the truss 1. The water traveling upward in the truss 1 is changed in direction by the guide plate 26 and hits the back surface 25a of the stopper 25 in the same manner as the wind example. Thereby, the stopper 25 is displaced so as to approach the hooked portion. When the stopper 25 approaches the hooked portion, the hook-shaped portion at the tip is arranged immediately below the hooked portion as shown by a broken line in FIG. Since the stopper 25 is hooked on the hooked portion, the floor plate 24 can be prevented from being lifted.

  FIG. 7 is a view showing another example of the man conveyor in the first embodiment of the present invention. FIG. 7 is a view corresponding to the BB cross section of FIG.

  The joint member 22 faces the floor plate 24 from the side. Depending on the type of the man conveyor, the joint member 22 is disposed at a position closer to the stopper 25 than the L angle 16c. In such a case, the stopper 25 is adjacent to the joint member 22 when the floor plate 24 is placed on the support angle 21. The stopper 25 is displaced so as to approach the joint member 22. When the stopper 25 approaches the joint member 22, the hook-shaped portion at the tip is disposed immediately below the joint member 22. In the example shown in FIG. 7, the hooked portion is a part of the joint member 22. The example shown in FIG. 7 can be expected to have the same effect as described above.

  FIG. 8 is a diagram showing another example of the man conveyor in the first embodiment of the present invention. FIG. 8 is a view corresponding to the BB cross section of FIG. 2. In the example illustrated in FIG. 8, the floor device 11 includes, for example, a pressing member 29 and a regulating member 30 in addition to the floor plate 24, the stopper 25, and the guide plate 26.

  In the example shown in FIG. 8, the guide plate 26 is provided on the floor plate 24 so that the end portion of the portion far from the stopper 25 can approach and separate from the floor plate 24. For example, the end portion of the guide plate 26 near the stopper 25 is provided on the reinforcing member 27 via the shaft 31.

  The pressing member 29 presses the guide plate 26 so that the end portion of the guide plate 26 far from the stopper 25 is separated from the floor plate 24. For example, the pressing member 29 pushes the guide plate 26 downward. FIG. 8 shows an example in which the pressing member 29 is a spring provided between the guide plate 26 and the floor plate 24.

  The restricting member 30 restricts the end portion of the guide plate 26 far from the stopper 25 from being separated from the floor plate 24 by a certain distance or more. FIG. 8 shows an example in which the regulating member 30 is a string provided between the guide plate 26 and the floor plate 24. When the floor plate 24 is placed on the support angle 21, the guide plate 26 is fixed at the position where the string is fully extended. In such a state, the lower surface of the guide plate 26 is disposed obliquely with respect to the upper surface of the floor plate 24.

  The maintenance staff of the man conveyor removes the floor apparatus 11 when performing maintenance work. The maintenance staff places the removed floor apparatus 11 on the floor adjacent to the man conveyor, for example. In the example shown in FIG. 8, when the floor device 11 is placed on a flat surface, the pressing member 29 is compressed by the weight of the floor plate 24. As a result, the guide plate 26 is displaced so as to approach the floor plate 24. In the example shown in FIG. 8, the floor apparatus 11 can be placed with the upper surface of the floor plate 24 kept horizontal. In order to prevent the guide plate 26 from colliding with the floor plate 24 when the floor apparatus 11 is placed on the floor or the like, a cushion member 32 may be provided on the reinforcing member 27 as shown in FIG.

Embodiment 2. FIG.
FIG. 9 is a diagram showing an example of a man conveyor in the second embodiment of the present invention. FIG. 9 is a diagram corresponding to the BB cross section of FIG. 2. The floor apparatus 11 shown in FIG. 9 includes a floor plate 24 and a stopper 25, for example.

  The stopper 25 is a member for preventing the floor plate 24 from being lifted. As shown by a broken line in FIG. 9, the floor plate 24 is prevented from being lifted by the stopper 25 being hooked on the hooked portion. FIG. 9 shows an example in which the hooked part is a part of the L angle 16c.

  The stopper 25 is disposed below the floor plate 24. The stopper 25 is adjacent to the hooked portion when the floor plate 24 is placed on the support angle 21. The stopper 25 is displaced so as to approach and separate from the covered portion. The stopper 25 is provided on the floor plate 24 via a shaft 28, for example.

  The stopper 25 includes a guide portion 33, for example. FIG. 9 shows an example in which the guide portion 33 is provided at the tip portion of the stopper 25. The guide part 33 makes the stopper 25 approach the hooked part by receiving the fluid on the lower surface. In the example shown in FIG. 9, since the stopper 25 includes the guide portion 33, the floor device 11 does not include the guide plate 26. The floor apparatus 11 may include a guide plate 26.

  When the floor plate 24 is placed on the support angle 21, the lower surface of the guide portion 33 is disposed obliquely with respect to the upper surface of the floor plate 24. For example, the guide portion 33 is disposed so as to approach the L angle 16c side as it goes downward. The lower end portion of the guide portion 33 is disposed at a position lower than the hooked portion.

  For example, when a man conveyor is installed at a station, wind enters the truss 1 when the train passes. An arrow F shown in FIG. 9 indicates a wind traveling upward in the truss 1. When the wind traveling upward in the truss 1 hits the lower surface of the guiding portion 33, the stopper 25 is displaced so as to approach the hooked portion. When the stopper 25 approaches the hooked portion, the tip portion is arranged immediately below the hooked portion as shown by a broken line in FIG. Since the stopper 25 is hooked on the hooked portion, the floor plate 24 can be prevented from being lifted. FIG. 9 shows an example in which a part of the guide portion 33 is arranged directly below the hooked portion.

  If no upward wind is generated in the truss 1, the tip portion of the stopper 25 is not arranged directly below the hooked portion as shown by the solid line in FIG. For this reason, for example, even if the maintenance staff of the man conveyor removes the floor apparatus 11 in order to perform maintenance work, the stopper 25 does not contact the hooked portion. Maintenance personnel can easily remove the floor apparatus 11.

  FIG. 10 is a diagram showing another example of the man conveyor in the second embodiment of the present invention. FIG. 10 is a view corresponding to the BB cross section of FIG. The floor apparatus 11 shown in FIG. 10 is different from the example shown in FIG. 9 in the shape of the stopper 25.

  In the example illustrated in FIG. 10, the stopper 25 includes, for example, a guide portion 33, a hook portion 34, and a displacement restricting portion 35. FIG. 10 shows an example in which the guide portion 33 is disposed between the hook portion 34 and the displacement restricting portion 35. The guide part 33 makes the stopper 25 approach the hooked part by receiving the fluid on the lower surface. In the example shown in FIG. 10, since the stopper 25 includes the guide portion 33, the floor device 11 does not include the guide plate 26. Also in the example illustrated in FIG. 10, the floor apparatus 11 may include the guide plate 26 as in the example illustrated in FIG. 9.

  The hanging portion 34 is a portion that is hung on the hanging portion in order to prevent the floor plate 24 from being lifted. When the stopper 25 approaches the hooked portion, the hooking portion 34 is disposed immediately below the hooked portion as indicated by a broken line in FIG.

  The displacement restricting portion 35 restricts the displacement of the stopper 25 so that the lower surface of the guiding portion 33 is disposed obliquely with respect to the upper surface of the floor plate 24. For example, when the floor plate 24 is placed on the support angle 21, the displacement restricting portion 35 contacts the lower surface of the floor plate 24 from below. When the displacement restricting portion 35 comes into contact with the floor plate 24, the guiding portion 33 is disposed so as to approach the L angle 16c side as it goes downward. The hanging part 34 is disposed at a position lower than the hanging part.

  For example, when a man conveyor is installed at a station, wind enters the truss 1 when the train passes. An arrow F shown in FIG. 10 indicates a wind traveling upward in the truss 1. When the wind traveling upward in the truss 1 hits the lower surface of the guiding portion 33, the stopper 25 is displaced so as to approach the hooked portion. When the stopper 25 approaches the hooked portion, the hooked portion 34 is disposed immediately below the hooked portion as shown by a broken line in FIG. Since the hanging portion 34 is hooked on the hanging portion, the floor plate 24 can be prevented from being lifted.

  If no upward wind is generated in the truss 1, the hanging portion 34 of the stopper 25 is not arranged directly below the hanging portion as shown by the solid line in FIG. For this reason, for example, even if the maintenance staff of the man conveyor removes the floor apparatus 11 in order to perform maintenance work, the stopper 25 does not contact the hooked portion. Maintenance personnel can easily remove the floor apparatus 11.

  For configurations not disclosed in the present embodiment, any configuration disclosed in Embodiment 1 may be employed.

Embodiment 3 FIG.
11 and 12 are diagrams showing examples of the man conveyor in the third embodiment of the present invention. 11 and 12 are views corresponding to the BB cross section of FIG. The floor apparatus 11 shown in the present embodiment includes, for example, a floor plate 24, a stopper 25, a pressing member 36, and a release member 37.

  A screw hole 24 a is formed in the floor plate 24. When the floor apparatus 11 is removed during maintenance, the removal tool 38 is screwed into the screw hole 24a. A portion of the tool 38 that is screwed into the screw hole 24a has a rod shape.

  The stopper 25 is a member for preventing the floor plate 24 from being lifted. The stopper 25 is disposed below the floor plate 24. The stopper 25 is adjacent to the hooked portion. The stopper 25 is displaced so as to approach and separate from the covered portion. FIG. 11 shows an example in which the stopper 25 is provided on the floor plate 24 via the shaft 28.

  The pressing member 36 presses the stopper 25 so that the stopper 25 approaches the hooked portion. When the stopper 25 is pressed against the pressing member 36, the hook-shaped portion at the tip is disposed immediately below the hooked portion as shown in FIG. Since the stopper 25 is hooked on the hooked portion, the floor plate 24 can be prevented from being lifted.

  The release member 37 is a member for releasing the lifting prevention function. The release member 37 releases the lifting prevention function by displacing the stopper 25 so that the stopper 25 is separated from the hooked portion. In the example shown in the present embodiment, the release member 37 displaces the stopper 25 by being pushed by the tip of the tool 38 screwed into the screw hole 24a.

  The release member 37 includes a rotating member 39 and a string-like member 40, for example. The rotating member 39 is rotatably provided on the floor plate 24. The rotating member 39 is disposed below the floor plate 24. A part of the rotating member 39 is disposed immediately below the screw hole 24a. The string-like member 40 is connected between the stopper 25 and the rotating member 39.

  In the example shown in FIGS. 11 and 12, when the tool 38 is screwed into the screw hole 24a, the tip of the tool 38 contacts the rotating member 39 from above. When the tool 38 is screwed into the screw hole 24a even after the tip of the tool 38 contacts the rotating member 39, the rotating member 39 is pushed by the tip of the tool 38 and rotates in a specific direction. In the example shown in FIG. 12, the rotating member 39 rotates clockwise. As the rotating member 39 rotates, the stopper 25 is pulled by the string-like member 40 so as to be separated from the hooked portion. Thereby, the stopper 25 comes off from the hooked portion. The maintenance staff can remove the floor apparatus 11 by lifting the tool 38 upward.
