DETAILED DESCRIPTION OF THE INVENTION

[0010] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. Duplicate descriptions of these parts will be appropriately simplified or omitted.

[0011] Embodiment 1 FIG. 1 is a perspective view of a roof device for a passenger conveyor according to the first embodiment.

[0012] FIG. 1 shows an escalator 1, which is a passenger conveyor. The escalator 1 is installed between an upper floor and a lower floor of a building. A first entrance 2a is installed on the upper floor of the building. A second entrance 2b is installed on the lower floor of the building. For example, a user moves between the upper and lower floors from the first entrance 2a through the movement area 3 of the escalator 1 and the second entrance 2b. Hereinafter, the left-right direction refers to the horizontal direction among directions perpendicular to the direction along the movement area 3.

[0013] A pair of balustrades 4 are provided on both sides of the moving area 3 in the left-right direction. For example, the balustrade 4 is made up of a member including a glass panel and a support pillar. The balustrade 4 may be made up of a metal plate or the like instead of a glass panel and a support pillar. Each of the pair of moving handrails 5 is an endless belt. The pair of moving handrails 5 is wound around the outer periphery of the pair of balustrades 4, respectively. The multiple steps 6 are connected to each other in an endless manner. The multiple steps 6 are provided below the moving area 3.

[0014] When the escalator 1 is in normal operation, the multiple steps 6 move in a circular motion between the upper and lower floors of the building. Each of the pair of moving handrails 5 moves in a circular motion around the corresponding balustrade 4 in synchronization with the multiple steps 6. Users move within the movement area 3 by standing on one of the multiple steps 6. In other words, the vertical range of the movement area 3 is the range from the top of the step 6 moving on the upper side to a specified height equivalent to a person's height. The horizontal range of the movement area 3 is the range from one of the pair of balustrades 4 to the other. The specified height equivalent to a person's height may be set arbitrarily to a value such as the maximum expected human height.

[0015] For example, when maintenance work is performed inside the escalator 1, some of the steps 6 are removed. A worker performs the maintenance work at the openings of the removed steps 6. At this time, a roof device 10 is installed on the escalator 1.

[0016] The roof device 10 is a temporary roof that is installed during maintenance work. For example, the roof device 10 is installed from the first entrance 2a to the second entrance 2b. The roof device 10 covers the top and both left and right sides of the moving area 3. The roof device 10 shields the opening and the worker from the surrounding environment. Therefore, for example, a user riding on another escalator installed next to the escalator 1 cannot see the opening and the worker because of the roof device 10.

[0017] The roof device 10 comprises a plurality of frame bodies 11, 12, 13, a shielding body 14, a pair of first supports 20, a pair of second supports 30, and a plurality of intermediate supports 40. The plurality of frame bodies 11, 12, 13 includes a first frame body 11, a second frame body 12, and a plurality of intermediate frame bodies 13.

[0018] For example, the first frame body 11 is formed in a U-shape. Lightweight materials such as carbon fiber and resin can be selected as the material for the first frame body 11. The material for the first frame body 11 may also be a metal such as aluminum. When the roof device 10 is installed, the first frame body 11 covers the moving area 3 in an arch shape. In this case, the first frame body 11 is positioned so that the opening of the U-shape faces downward. Both ends of the first frame body 11 are respectively located above the pair of moving handrails 5. Therefore, the first frame body 11 is positioned at the top and both left and right sides of the moving area.

[0019] For example, the shape and material of the second frame body 12 are the same as those of the first frame body 11. When the roof device 10 is installed, the second frame body 12 is aligned with the first frame body 11 along the movement area 3. The second frame body 12 is disposed in the same posture as the first frame body 11.

[0020] For example, the shape and material of the multiple intermediate frame bodies 13 are all the same as the shape and material of the first frame body 11. When the roof device 10 is installed, the multiple intermediate frame bodies 13 are lined up along the movement area 3 between the first frame body 11 and the second frame body 12. Each of the multiple intermediate frame bodies 13 is arranged in the same posture as the first frame body 11.

[0021] The shielding body 14 is a foldable sheet. For example, the material of the shielding body 14 may be an opaque material such as a fireproof cover or opaque vinyl. A particularly lightweight material may be used for the material of the shielding body 14. The shielding body 14 is provided so as to cover the first frame body 11, the second frame body 12, and the plurality of intermediate frame bodies 13, respectively. The shielding body 14 is fixed to the first frame body 11, the second frame body 12, and the plurality of intermediate frame bodies 13.

[0022] Although not shown, the portions of the shielding body 14 between the plurality of frame bodies 11, 12, and 13 can be folded. That is, the plurality of frame bodies 11, 12, and 13 and the shielding body 14 are formed so as to have an accordion-like shape as a whole. Note that the shielding body 14 may be formed by connecting a plurality of materials rather than by connecting one material.

[0023] When the roof device 10 is in an installed state where it is installed on the escalator 1, the shielding body 14 covers the moving area 3. When the roof device 10 is in a ready state where it is not installed on the escalator 1, the shielding body 14 is folded so that its length is shortened in the direction in which the multiple frame bodies 11, 12, and 13 are lined up.

[0024] The pair of first supports 20 are provided at both ends of the first frame 11. When the roof device 10 is attached to the escalator 1, one of the pair of first supports 20 is provided between one end of the first frame 11 and one of the pair of moving handrails 5. The other of the pair of first supports 20 is provided between the other end of the first frame 11 and the other of the pair of moving handrails 5. Each of the pair of first supports 20 has a similar configuration.

[0025] The first support 20 supports the load of the first frame 11. The first support 20 is attached to the escalator 1 in either a first configuration or a second configuration.

[0026] In the first form, the first support body 20 is detachably fixed to the moving handrail 5 so as not to move relative to the moving handrail 5. The first support body 20 has a load supported by the moving handrail 5.

[0027] In the second form, the first support 20 is fixed to the balustrade 4 so as not to move relative to the balustrade 4. In this case, the first support 20 is movable relative to the moving handrail 5 while the load is supported by the moving handrail 5.

[0028] The second supports 30 are provided at both ends of the second frame 12. When the roof device 10 is attached to the escalator 1, one of the pair of second supports 30 is located between one end of the second frame 12 and one of the pair of moving handrails 5. The other of the pair of second supports 30 is located between the other end of the second frame 12 and the other of the pair of moving handrails 5. Each of the pair of second supports 30 has a similar configuration.

[0029] The second support 30 is detachably fixed to the balustrade 4 so as not to move relative to the balustrade 4. In this case, the second support 30 is movable relative to the moving handrail 5 while the load is supported by the moving handrail 5.

[0030] Each of the multiple intermediate supports 40 has the same configuration. The multiple intermediate supports 40 are provided at the ends of the multiple intermediate frame bodies 13, respectively. Specifically, a pair of intermediate supports 40, which are two of the multiple intermediate supports 40, are provided at both ends of one intermediate frame body 13. When the roof device 10 is attached to the escalator 1, one of the pair of intermediate supports 40 is located between one end of the intermediate frame body 13 and one of the pair of moving handrails 5. The other of the pair of intermediate supports 40 is located between the other end of the intermediate frame body 13 and the other of the pair of moving handrails 5.

[0031] The intermediate support body 40 is attached to the moving handrail 5. In this case, the intermediate support body 40 is movable relative to the moving handrail 5 while the load is supported by the moving handrail 5.

[0032] Next, the shield 14 will be described with reference to FIG. 2 is a side view of a main part of the roof device for the passenger conveyor in Embodiment 1. Note that the first frame 11 is not shown in FIG.

[0033] As shown in FIG. 2, the shield 14 includes an air passage 15 and a plurality of air outlets 16.

[0034] The air passage section 15 is a tube made of the same material as the shielding body 14. The air passage section 15 is provided from one end to the other end of the shielding body 14 in the direction in which the multiple frame bodies 11, 12, 13 are arranged. For example, when the roof device 10 is in the installed state, the air passage section 15 is located above the movement area 3. Inside the air passage section 15, a single connected cylindrical air passage space is formed.

[0035] Each of the plurality of air outlets 16 is a hole provided in air passage 15. Each of the plurality of air outlets 16 is provided on a surface of air passage 15 of shielding body 14 facing movement area 3. For example, air outlet 16 is located between the plurality of frame bodies 11, 12, and 13. For example, air outlet 16 is provided so as to be able to be opened and closed by a lid or the like (not shown).

[0036] For example, a spot cooler 100 is connected to the end of the air passage 15 on the second entrance / exit 2b side. Of the multiple air outlets 16, some air outlets 16 close to where the worker is working are opened. The spot cooler 100 sends air into the air passage 15. The sent air passes through the air passage space of the air passage 15 and is sent out from the open air outlets 16. The area around the worker is cooled by this air.

[0037] The roof device 10 further comprises a plurality of electrical connection terminals 17 and wiring 18 .

[0038] Each of the electrical connection terminals 17 is a plug that transmits or receives an electrical signal. For example, the electrical connection terminals 17 are provided at the air outlets 16, respectively.

[0039] The wiring 18 is a conductor that transmits an electrical signal. The wiring 18 is disposed inside the air passage 15. The wiring 18 is electrically connected to the plurality of electrical connection terminals 17, respectively.

[0040] For example, among the multiple electrical connection terminals 17, the electrical connection terminal 17 located closest to the location where the worker works is electrically connected to the speaker 101 and the microphone 102. Specifically, the jacks of the speaker 101 and the microphone 102 are inserted into the plugs of the electrical connection terminal 17.

[0041] The worker can hear the voice from the speaker 101. The worker can transmit the voice to the outside using the microphone 102. In other words, the worker can communicate with a supervisor who is located far away from the worker via the speaker 101 and the microphone 102.

[0042] Next, the first support 20 will be described with reference to FIG. FIG. 3 is a diagram showing a first support body of a roof device for a passenger conveyor in the first embodiment.

[0043] 3 shows a first embodiment of the first support 20. The first support 20 has a first base portion 21, a first roller portion 22, a gripping portion 23, a reinforcing portion 24, and a first fixing portion 25.

[0044] The first base 21 is attached to an end of the first frame 11. For example, the first base 21 extends in the left-right direction from the connection position with the first frame 11. A lower surface 21a is formed on the first base 21. The lower surface 21a is the surface on the opposite side to the connection position with the first frame 11.

[0045] The first roller portion 22 is provided on the lower surface 21a of the first base portion 21. The first roller portion 22 has an arm 22a and a roller 22b. The arm 22a extends from the lower surface 21a. The roller 22b is provided rotatably with respect to the arm 22a.

[0046] When the roof device 10 is attached to the escalator 1, the first roller portion 22 can move relative to the moving handrail 5 while the load is supported by the moving handrail 5. Specifically, the roller 22b contacts the upper surface of the moving handrail 5. At this time, the roller 22b rolls while in contact with the moving handrail 5, thereby rotating in the direction of movement of the moving handrail 5. The arm 22a rotatably supports the roller 22b and transmits the load from the first base portion 21 to the roller 22b. In other words, the first roller portion 22 supports the load on the moving handrail 5 while rotating relative to the moving handrail 5.

[0047] The gripping portion 23 has two arms 23a. The two arms 23a extend from the lower surface 21a of the first base portion 21. The gripping portion 23 can grip the moving handrail 5 from the left and right directions with the two arms 23a.

[0048] When the first support body 20 is in the first form, the gripping portions 23 grip the moving handrail 5 from the left and right. In this case, the first support body 20 is fixed to the moving handrail 5 so as not to move relative to it.

[0049] Although not shown, when the first support body 20 is in the second configuration, the gripping portion 23 does not grip the moving handrail 5. In this case, the first support body 20 can move relative to the moving handrail 5.

[0050] When the first support body 20 is in the first configuration, the reinforcing portion 24 is attached to the gripping portion 23 as a reinforcing member. The reinforcing portion 24 increases the force with which the gripping portion 23 grips the moving handrail 5. Specifically, the reinforcing portion 24 applies force to the two arm portions 23a in a direction that increases the gripping force. Although not shown, when the first support body 20 is in the second configuration, the reinforcing portion 24 does not have to be attached to the first support body 20.

[0051] The first fixing portion 25 has two arms 25a and two fixing ends 25b. The two arms 25a extend from the lower surface 21a. The two arms 25a are positioned outward of the two arms 23a. The two fixing ends 25b are provided at the tips of the two arms 25a, respectively. For example, the two fixing ends 25b include suction cups.

[0052] Although not shown, when the first support 20 is in the second form, the first fixing portion 25 is fixed to the balustrade 4. Specifically, for example, suction cups, which are the two fixed ends 25b, are attached to the surface of the balustrade 4. In this case, the first support 20 is fixed to the balustrade 4 so as not to move relative to the balustrade 4. On the other hand, when the first support 20 is in the first form, the first fixing portion 25 is not fixed to the balustrade 4. In this case, the first support 20 is movable relative to the balustrade 4.

[0053] Next, the second support 30 will be described with reference to FIG. FIG. 4 is a view showing a second support body of the roof device of the passenger conveyor in the first embodiment.

[0054] 4 shows the second support 30 attached to the escalator 1. The second support 30 has a second base portion 31, a second roller portion 32, and a second fixed portion 33.

[0055] The second base 31 is attached to an end of the second frame 12. For example, the second base 31 extends in the left-right direction from the position where it is connected to the second frame 12. A lower surface 31a is formed on the second base 31. The lower surface 31a is the surface on the opposite side to the position where it is connected to the second frame 12.

[0056] The second roller portion 32 has the same configuration as the first roller portion 22 in the first support body 20, which is not shown in Fig. 4. That is, the second roller portion 32 has an arm 32a and a roller 32b. When the roof device 10 is attached to the escalator 1, the second roller portion 32 can move relative to the moving handrail 5 while the load is supported by the moving handrail 5.

[0057] The second fixed portion 33 has the same configuration as the first fixed portion 25 of the first support 20. That is, the second fixed portion 33 has two arm portions 33a and two fixed end portions 33b.

[0058] The second fixing portion 33 is fixed to the balustrade 4. Specifically, for example, suction cups that are the two fixing ends 33b are attached to the surface of the balustrade 4. In this case, the second support 30 is fixed to the balustrade 4 so as not to move relative to the balustrade 4.

[0059] Next, the intermediate support 40 will be described with reference to FIG. FIG. 5 is a diagram showing an intermediate support member of a roof device for a passenger conveyor according to the first embodiment.

[0060] 5 shows the intermediate support 40 attached to the escalator 1. The intermediate support 40 has an intermediate base portion 41, an intermediate roller portion 42, and a guide portion 43.

[0061] The intermediate base 41 is attached to an end of the intermediate frame 13. For example, the intermediate base 41 extends in the left-right direction from the connection position with the intermediate frame 13. A bottom surface 41a is formed on the intermediate base 41. The bottom surface 41a is the surface on the opposite side to the connection position with the intermediate frame 13.

[0062] The intermediate roller portion 42 has the same configuration as the first roller portion 22 in the first support body 20, which is not shown in Fig. 5. That is, the intermediate roller portion 42 has an arm 42a and a roller 42b. When the roof device 10 is installed, the intermediate roller portion 42 can move relative to the moving handrail 5 while the load is supported by the moving handrail 5.

[0063] The guide portion 43 has two arms 43a and two guide rollers 43b. The two arms 43a extend from the lower surface 41a. The two guide rollers 43b are rotatably provided below the two arms 43a. For example, the width of the two guide rollers 43b is the same as the width of the moving handrail 5 in the left-right direction. The two guide rollers 43b contact the moving handrail 5 so as to sandwich the moving handrail 5 between them. Each of the two guide rollers 43b can rotate while in contact with the moving handrail 5.

[0064] When the intermediate support body 40 moves relative to the moving handrail 5, the guide portion 43 guides the intermediate support body 40 so that the intermediate support body 40 does not move in the left-right direction relative to the moving handrail 5.

[0065] Next, a method for installing the roof device 10 will be described with reference to FIG. Fig. 6 is a perspective view of a state in which the roof device for the passenger conveyor according to the first embodiment is attached to the second entrance / exit. Note that the first entrance / exit 2a is not shown in Fig. 6.

[0066] The method for installing the roof device 10 includes a first installation step, a second installation step, a third installation step, a moving step, and a fixing step.

[0067] 6 shows the roof device 10 after the first, second, and intermediate installation steps have been performed. In preparation for the first, second, and third installation steps, a worker carries the roof device 10, which is folded accordion-like and in a ready state, to the second entrance / exit 2b of the escalator 1.

[0068] In the first attachment step, the worker attaches each of the pair of first supports 20 to the corresponding moving handrail 5 in a first configuration. That is, the worker fixes the first supports 20 to the moving handrail 5 so that the first supports 20 do not move relative to the moving handrail 5.

[0069] In the second installation step, the worker installs each of the pair of second supports 30 to the corresponding balustrade 4. That is, the worker installs the second supports 30 to the balustrade 4 so that the second supports 30 do not move relative to the balustrade 4. The second supports 30 can move relative to the moving handrail 5 while the load is supported by the moving handrail 5.

[0070] In the intermediate attachment step, workers attach each of the multiple intermediate supports 40 to the corresponding moving handrail 5. That is, workers attach the intermediate supports 40 to the moving handrail 5 so that the intermediate supports 40 can move relative to the moving handrail 5 and so that the intermediate supports 40 can move along the moving handrail 5.

[0071] The first mounting step, the second mounting step, and the intermediate mounting step may be performed in any order. Although not shown, after the first mounting step, the second mounting step, and the intermediate mounting step are performed, the moving step is performed.

[0072] The moving process is a process of expanding the roof device 10, which is in a folded state after installation, to the length of the installed state. In the moving process, a worker moves the escalator 1 from the side of the second entrance 2b to the side of the first entrance 2a. The moving handrail 5 and step 6 of the escalator 1 move.

[0073] While the movement process is being carried out, the second support 30 does not move from the position on the balustrade 4 to which it is attached. The pair of first supports 20 move together with the moving handrail 5 as the moving handrail 5 moves. The first frame 11 moves together with the pair of first supports 20. At this time, the first frame 11 pulls the shielding body 14 in the direction of movement of the moving handrail 5. The force pulling from the first frame 11 causes the shielding body 14 to expand from its folded state in the direction of movement of the moving handrail 5.

[0074] Immediately after the first frame body 11 starts moving, each of the multiple intermediate supports 40 does not move together with the moving handrail 5. Each of the multiple intermediate supports 40 moves together with the shielding body 14, which is expanding from its folded state. Specifically, when the shielding body 14 is pulled a certain distance by the first frame body 11, the portion of the shielding body 14 that exists between the first frame body 11 and the intermediate frame body 13 adjacent to the first frame body does not expand any further. In this case, the shielding body 14 pulls the intermediate frame body 13 in the direction of movement of the moving handrail. Because the intermediate support body 40 can move relative to the moving handrail 5, the intermediate frame body 13 moves together with the intermediate support body 40 in the direction of movement of the moving handrail due to the force of the pulling from the shielding body 14. Thereafter, the portion of the shielding body 14 that exists between the intermediate frame body 13 and the intermediate frame body 13 adjacent to the intermediate frame body 13 on the opposite side of the first frame body 11 from the first frame body 11 does not expand any further. Thereafter, each of the multiple intermediate frame bodies 13 moves sequentially in the movement direction of the moving handrail 5 in the same manner.

[0075] Thereafter, when first support 20 reaches the installed position, the worker stops escalator 1 and ends the moving process. Specifically, when first support 20 reaches first entrance 2a as shown in FIG. 1, the worker ends the moving process. Note that the installed state is not limited to the state shown in FIG. 1. For example, the worker may end the moving process when the entire shielding body 14 has stretched to the point where it cannot be expanded any further. In this case, first support 20 may be located at a position on escalator 1 between first entrance 2a and second entrance 2b.

[0076] After the moving process, the fixing process is carried out. In the fixing process, the worker puts each of the pair of first supports 20 present at the installation position into the second state. That is, the worker attaches the first fixing portion 25 of the first support 20 to the corresponding balustrade 4. The worker releases the gripping portion 23 of the first support 20 from the corresponding moving handrail 5. As a result, the first support 20 becomes movable relative to the moving handrail 5. The first support 20 is fixed so that it cannot move relative to the balustrade 4.

[0077] When the moving process is completed, the roof device 10 is in the installed state. The worker completes the installation of the roof device 10 using the installation method. For example, in the installed state, the worker can move the moving handrail 5 and step 6 of the escalator 1 to any location. At this time, the roof device 10 does not move relative to the moving handrail 5.

[0078] Although not shown, the installation method may further include an additional step. In the additional step, the worker attaches the spot air cooler 100 to the air duct 15. The worker opens the air outlet 16 closest to the work location among the multiple air outlets 16. The worker attaches the speaker 101 and the microphone 102 to the electrical connection terminal 17 closest to the work location among the multiple electrical connection terminals 17. By performing the additional step, a safe and efficient work environment is created.

[0079] According to the first embodiment described above, the roof device 10 comprises a first frame body 11, a second frame body 12, an intermediate frame body 13, a shielding body 14, a first support body 20, and an intermediate support body 40. The first support body 20 is fixed to the moving handrail 5. The intermediate support body 40 is attached to the moving handrail 5 in a state where it is movable relative to the moving handrail 5. In the installation method of the roof device 10, when the moving handrail 5 is moved with the first support body 20 and the intermediate support body 40 attached in this manner, the first support body 20 and the first frame body 11 move together with the moving handrail 5 to the installation position of the roof device 10. The first frame body 11 pulls the shielding body 14 in the direction of movement. The intermediate support body 40 and the intermediate frame body 13 are pulled by the shielding body 14 and move to the installation position of the roof device 10. That is, in the work of installing the roof device 10, the worker can install the roof device 10 by attaching it to the side of the second entrance / exit 2b and then operating the escalator 1. As a result, the worker can easily install the roof device 10.

[0080] By installing the roof device 10, users around the escalator 1 cannot see the worker or the opening in the step 6. This prevents the worker from being distracted by being seen by people around them while performing maintenance on the passenger conveyor. It also prevents people around them from seeing the inside of the passenger conveyor through the opening. Furthermore, by covering the worker's work area with the roof device 10, it prevents the worker from being exposed to direct sunlight. This improves the worker's work environment. By covering the work area with the roof device 10, it prevents oil, splashes, etc. that may be scattered during work from scattering outside the moving area 3 of the escalator 1. By covering the work area with the roof device 10, it prevents objects from entering the opening from the outside. This improves the workability of maintenance work.

[0081] Furthermore, the first support 20 has a first roller portion 22 and a grip portion 23. The intermediate support 40 has an intermediate roller portion 42. Therefore, the first support 20 is detachably fixed to the moving handrail 5. The intermediate support 40 supports a load so as to be movable relative to the moving handrail 5.

[0082] Moreover, the first support body 20 further has a first fixing portion 25. Therefore, in the second configuration, the first support body 20 is fixed to the balustrade 4. As a result, the roof device 10 can be stably installed on the escalator 1.

[0083] In addition, in the second form, the first support 20 is fixed to the balustrade 4 in a state in which it is movable relative to the moving handrail 5. Therefore, when the roof device 10 is installed, the moving handrail 5 can be moved independently of the roof device 10.

[0084] The roof device 10 further includes a second support 30. The second support 30 fixes the end of the roof device 10 opposite the first support 20 to the parapet 4. This allows the roof device 10 to be installed stably.

[0085] The shield 14 is also provided with an air passage 15 and a plurality of air outlets 16. This allows air to be sent to the work area. For example, cooling air can be sent to the work area. As a result, the working environment for the workers can be improved.

[0086] Furthermore, each of the multiple air outlets 16 can be opened and closed. Therefore, air can be sent only from the air outlet 16 closest to the work location. As a result, the work environment of the workers can be improved efficiently.

[0087] The roof device 10 also includes wiring 18 and a plurality of electrical connection terminals 17. A microphone and a speaker can be electrically connected to the electrical connection terminals 17. The wiring 18 can transmit electrical signals between the microphone and the speaker. This allows communication with workers at the work site from a location remote from the work site. For example, workers can consult with a supervisor at a remote location about the work content. As a result, the efficiency of maintenance work can be improved. Furthermore, the safety of maintenance work can be improved.

[0088] The shield 14 may have a double structure in which the same material is folded back. In this case, the air passage 15 may be a space surrounded by the double structure. The air may be blown from the air outlet 16 through the space surrounded by the double structure.

[0089] In the first mounting step, the second mounting step, and the intermediate mounting step of the installation method, the roof device 10 may be mounted on the side of the first entrance 2a instead of the side of the second entrance 2b. In this case, in the moving step, the roof device 10 spreads out together with the moving handrail 5 from the side of the first entrance 2a toward the side of the second entrance 2b.

[0090] The roof device 10 can be easily dismantled by performing each step in the reverse order of the installation method. Specifically, first, in the reverse order of the fixing step, the worker fixes the first support 20 to the moving handrail by putting the first support into the first configuration. Then, the worker moves the moving handrail 5 and the step 6 in the opposite direction to the movement direction in the moving step. As this movement occurs, the first frame body 11 moves toward the second entrance 2b. The shielding body 14 is folded from its unfolded state. Each of the multiple intermediate frame bodies 13 moves together with the shielding body 14. Each of the multiple intermediate support bodies 40 moves together with the corresponding intermediate frame body 13. When the first frame body 11 arrives at the second entrance 2b, the roof device 10 is in the state shown in FIG. 6. Then, the worker removes the first support 20, the second support 30, and the intermediate support 40 from the moving handrail 5 or the balustrade 4. Thereafter, the worker finishes the work of putting away the roof device 10.

[0091] In addition, in the roof device 10, after the first support body 20 is attached to the moving handrail 5, the multiple intermediate support bodies 40 may be attached to the moving handrail 5 in order. FIG. 7 is a perspective view of a second entrance / exit in another example where the roof device of the passenger conveyor according to the first embodiment is attached.

[0092] As shown in Figure 7, after the first support body 20 is attached to the moving handrail 5, the worker moves the moving handrail 5 and the step 6 to the side of the first entrance 2a, which is not shown in Figure 7. After the moving handrail 5 has moved a certain distance, the worker stops the movement of the moving handrail 5. The worker attaches the intermediate frame body 13 adjacent to the first frame body 11 and the corresponding intermediate support body 40 to the moving handrail 5.

[0093] After that, the worker moves the movable handrail 5 a certain distance, stops it, and attaches the next intermediate frame body 13 and intermediate support body 40 to the movable handrail 5. The worker repeats this series of tasks to sequentially attach multiple intermediate frame bodies 13 to the movable handrail 5. After attaching the last intermediate frame body 13, the worker fixes the second frame body 12 and second support body 30 to the balustrade 4. The worker then performs the fixing process, completing the installation work. In other words, this example of an installation method is a method in which the intermediate attachment process and the moving process are repeated.

[0094] In the installation method described above, the worker can perform the intermediate installation step and the moving step at the position of the second entrance 2b, which allows the worker to easily install the roof device 10.

[0095] The roof device 10 may also be applied to passenger conveyors other than escalators, such as moving walkways for moving passengers in a horizontal direction. [Explanation of symbols]
