In the stored state, the rotation of the scaffolding member 22 is restricted by the insert 26 and the clamp 27.

[0066] In the stored state, the insert 26 and the clamping tool 27 that are clamped by the clamping tool 27 can be separated in the rotational direction of the scaffold member 22 as described below.

[0067] As shown in FIG. 11 , in the stored state, the hook portion 24a is lowered from the landing entrance 9 below the hoistway 1, hooked onto the scaffolding member 22, and moved toward the inside of the hoistway 1, so that the scaffolding member 22 is pulled toward the inside of the hoistway 1 by the hook portion 24a and rotates, and the insert 26 and the clamp 27 move away from each other in the rotational direction of the scaffolding member 22.

[0068] For example, the hook portion 24a can be hooked onto the scaffolding member 22 by lowering the hook portion 24a from the landing entrance 9 to below the hoistway 1 and then moving it upward through the penetration portion 22c of the scaffolding member 22. Also, for example, the hook portion 24a can be hooked onto the scaffolding member 22 by lowering the hook portion 24a from the landing entrance 9 to below the hoistway 1 and then moving it upward from below the scaffolding member 22.

[0069] In a state where the hook portion 24a is hooked to the scaffolding member 22, the side of the support bar 24 opposite the hook portion 24a can be located above the landing threshold 10. For example, after the hook portion 24a is hooked to the scaffolding member 22, the middle portion of the support bar 24 is brought into contact with the landing threshold 10, and the side of the support bar 24 opposite the hook portion 24a is moved toward the landing entrance 9, so that the hook portion 24a moves toward the inside of the hoistway 1. Also, for example, after the hook portion 24a is hooked to the scaffolding member 22, the side of the support bar 24 opposite the hook portion 24a is positioned more inside the hoistway 1 than the hook portion 24a in the depth direction of the landing entrance 9, and the support bar 24 is pulled up in the longitudinal direction of the support bar 24, so that the hook portion 24a moves toward the inside of the hoistway 1.

[0070] Here, the hook portion 24b may be used instead of the hook portion 24a, and the support rod 25 may be used instead of the support rod 24.

[0071] The scaffolding members 22, hinges 23, support bars 24 and 25, inserts 26 and clamps 27 are provided as described above.

[0072] The scaffolding apparatus 21 can be switched from the stowed state to the assembled state as follows.

[0073] For example, after the insertion tool 26 and the clamping tool 27 are released from the stored state in the rotation direction of the scaffolding member 22, the hook portion 24a is lowered from the landing entrance 9 to below the hoistway 1, and then passed through the through-hole 22c and moved upward to hook onto the scaffolding member 22, and then moved toward the inside of the hoistway 1, so that the scaffolding member 22 is pulled toward the inside of the hoistway 1 by the hook portion 24a and rotates, and further the hook portion 24b is hooked onto the reinforcing plate 16a of the vertical frame 16. Similarly, the hook portion 25a is hooked onto the scaffolding member 22, and the support rod 25 is hooked onto the reinforcing plate 17a of the vertical frame 17, so that the scaffolding member 22 is in the assembled state.

[0074] The procedure for switching from the assembled state to the stored state is the reverse of the procedure for switching from the stored state to the assembled state.

[0075] When switching from the assembled state to the stored state, the insert 26 can be inserted into the clamp 27 without using the support rods 24 and 25. For example, after the support rods 24 and 25 are removed, the scaffold member 22 rotates by its own weight, and the insert 26 is inserted into the clamp 27.

[0076] The elevator scaffolding device 21 in the first embodiment is provided as described above.

[0077] When the scaffolding device 21 is switched from the stored state to the assembled state, appropriate measures are taken to prevent people from falling through the open landing entrance 9. For example, a fence or handrail is provided between the vertical frames 16 and 17.

[0078] In addition, when the scaffolding device 21 is switched from the stored state to the assembled state, appropriate measures are taken to prevent the opened landing entrance 9 from being closed unintentionally. For example, when the landing entrance 9 is opened, wedges are fitted into the grooves 10a and 10b of the landing threshold 10 on the side of the landing doors 13 and 14 in the fully closed position.

[0079] In addition, after the scaffolding device 21 is switched from the stored state to the assembled state, appropriate measures are taken to prevent falling from the scaffolding member 22. For example, fences and handrails are provided along the edges of the scaffolding member 22. In this case, the fences and handrails can be attached to the scaffolding member 22, the support rods 24 and 25, the platform jamb 11, etc.

[0080] The elevator scaffolding device 21 in the first embodiment is an elevator scaffolding device that is provided in an elevator device and can be switched between an assembled state in which it forms a scaffold connecting to the landing entrance 9 in the hoistway and a stored state in which it forms an entrance protection member for the landing entrance 9 in the hoistway, and includes a scaffolding member 22, a hinge 23, and support rods 24 and 25, the hinge 23 is provided below the landing entrance 9 and has a rotation axis 23a oriented in the width direction of the landing entrance 9, and the scaffolding member 22 is The scaffolding member 22 is attached to a hinge 23 and rotated around a rotation axis 23a to be switched between an assembled state and a stored state. In the assembled state, the scaffolding member 22 extends from the hinge 23 inside the elevator shaft 1 in the width and depth directions of the landing entrance 9, and the support rods 24 and 25 connect the scaffolding member 22 to the outer periphery of the landing entrance 9 above the scaffolding member 22. In the stored state, the scaffolding member 22 extends from the hinge 23 downward in the width and vertical directions of the landing entrance 9.

[0081] As a result, when workers move between the scaffolding in the hoistway 1 formed by the scaffolding device 21 and the landing entrance / exit 9, they do not need to descend into the hoistway pit, which is the bottom of the hoistway 1.

[0082] In addition, workers can set up scaffolding inside the hoistway 1 without having to set up a stepladder at the bottom of the hoistway 1.

[0083] Furthermore, workers can use the scaffolding device 21 regardless of the depth from the landing entrance 9 to the bottom of the elevator shaft 1.

[0084] In addition, the scaffolding member 22 can be accommodated in the space in which the entrance / exit protection member is installed.

[0085] In addition, the worker can hook the hook of the safety belt onto the support member 24 or 25.

[0086] It is effective to provide a scaffolding device 21 that connects to the landing entrance 9 of the landing 2 on the lowest floor among the multiple landings 2 at which the car 5 stops. In many elevator devices, it is difficult to move from the landing entrance 9 of the landing 2 on the lowest floor to the upper part of the car 5. The descent of the car 5 is restricted so as not to hit the equipment at the bottom of the elevator shaft 1.

[0087] The elevator scaffolding device 21 in embodiment 1 is an elevator scaffolding device provided in an elevator system in which the landing door 9 is opened and closed between a fully closed state and a fully open state by the landing doors 13 and 14 moving between a fully closed position and a fully open position when the elevator system is in operation, and in the assembled state, the landing door 9 is open, and the support rods 24 and 25 are positioned on the fully closed position side of the landing doors 13 and 14.

[0088] As a result, in the assembled state, the landing doors 13 and 14 are held in an open position by the support rods 24 and 25, allowing workers to easily move between the scaffolding in the elevator shaft 1 formed by the scaffolding device 21 and the landing entrance 9.

[0089] The elevator scaffolding device 21 in embodiment 1 is provided in an elevator device that does not raise or lower the car 5 when the landing entrance / exit switch detects that the landing entrance / exit 9 is in a fully closed state, and when the landing entrance / exit switch does not detect that the landing entrance / exit 9 is in a fully closed state.

[0090] This makes it possible to prevent the car 5 from rising and falling and colliding with the scaffolding device 21 in the assembled state.

[0091] The elevator scaffolding device 21 in embodiment 1 is an elevator scaffolding device provided in an elevator device in which the sides and upper part of a landing entrance / exit 9 are formed by a landing jamb 11, and in an assembled state, support rods 24 and 25 connect the scaffolding member 22 to the landing jamb 11.

[0092] This makes it possible to easily attach the support rods 24 and 25 to the outer periphery of the landing entrance 9 above the scaffolding member 22, regardless of the structure of the elevator shaft 1.

[0093] The elevator scaffolding device 21 in embodiment 1 is an elevator scaffolding device provided in an elevator system in which the landing entrance 9 is opened and closed by moving the landing doors 13 and 14 in the width direction of the landing entrance 9, and in which the landing doors 13 and 14 can be opened further than the fully open position during maintenance of the elevator system, and in an assembled state, the landing doors 13 and 14 are opened further than the fully open position, and the support rod 24 is attached to the hoistway 1 side of the vertical frame 16 of the landing jamb 11 that forms the side of the landing entrance 9, and the support rod 25 is attached to the hoistway 1 side of the vertical frame 17 of the landing jamb 11 that forms the side of the landing entrance 9.

[0094] This allows a worker to easily attach the support rods 24 and 25 to the landing jamb 11 from the landing entrance / exit 9.

[0095] In embodiment 1, the elevator scaffolding device 21 has a landing fixture 15 attached to a vertical frame 16, the landing fixture 15 being an elevator scaffolding device provided in an elevator device that can be maintained from the hoistway 1 side, and in the assembled state, the scaffolding member 22 is located below the landing fixture 15, and the support rod 24 is located outside the landing entrance / exit 9 relative to the landing fixture 15.

[0096] This allows workers to perform maintenance on the landing equipment 15 from the side of the hoistway 1 without being hindered by the support rod 24.

[0097] The elevator scaffolding device 21 in the first embodiment is an elevator scaffolding device provided in an elevator device in which the lower part of a landing entrance 9 is formed by a landing threshold 10, and the hinge 23 is attached to the landing threshold 10.

[0098] This allows the hinge 23 to be easily provided below the landing entrance 9 regardless of the structure of the elevator shaft 1.

[0099] In the elevator scaffolding device 21 in embodiment 1, the support bar 24 has a hook portion 24a at one longitudinal end, and in the stored state, the hook portion 24a can be hooked onto the scaffolding member 22 from the landing entrance / exit 9 and moved toward the inside of the hoistway 1, thereby rotating the scaffolding member 22 toward the inside of the hoistway 1, and the other end of the support bar 24 can be attached to the outer periphery of the landing entrance / exit 9 above the scaffolding member 22, thereby placing the scaffolding device in an assembled state.

[0100] This allows a worker to switch between the stored state and the assembled state using the support rod 24 from the landing entrance / exit 9.

[0101] Similarly, a worker can switch between the stored state and the assembled state by using the support rod 25 from the landing entrance 9.

[0102] The elevator scaffolding device 21 in embodiment 1 is equipped with an insert 26 and a clamp 27, one of the insert 26 and the clamp 27 being provided on the scaffolding member 22 and the other of the insert 26 and the clamp 27 being provided on the hoistway 1, and in the stored state, the insert 26 is inserted into the clamp 27 in the rotational direction of the scaffolding member 22, thereby preventing the scaffolding member 22 from rotating.

[0103] As a result, when the elevator device is in operation, the inserting tool 26 and the clamping tool 27 can prevent the scaffolding member 22 from rotating from the stored state toward the inside of the hoistway 1 and hitting the car 5. For example, it is possible to prevent the scaffolding member 22 from rotating toward the inside of the hoistway 1 due to wind pressure generated when the car 5 rises and falls, an updraft generated in the hoistway 1 due to the temperature difference between the inside and outside of the building in which the elevator device is installed in winter, the shaking of the building in which the elevator device is installed, and the like.

[0104] In the elevator scaffolding device 21 in embodiment 1, the insert 26 is a reinforcing plate 22b provided on the scaffolding member 22, and the reinforcing plate 22b is provided between the side of the hinge 23 and the side opposite the hinge 23 on the scaffolding member 22.

[0105] This eliminates the need to provide the reinforcing plate 22b and the insert 26 separately.

[0106] In the elevator scaffolding device 21 in embodiment 1, the support bar 24 has a hook portion 24a at one longitudinal end, and in the stored state, the hook portion 24a is lowered from the landing entrance 9 to below the hoistway 1 and hooked onto the scaffolding member 22 and moved inwardly of the hoistway 1, so that the scaffolding member 22 is pulled inwardly of the hoistway 1 by the hook portion 24a and rotates, and the insert 26 and the clamp 27 move apart in the rotational direction of the scaffolding member 22.

[0107] This allows the worker to separate the insertion tool 26 and the clamping tool 27 in the rotation direction of the scaffold member 22 using the support rod 24 from the landing entrance / exit 9.

[0108] Similarly, the worker can separate the insert tool 26 and the clamping tool 27 in the rotation direction of the scaffold member 22 using the support rod 25 from the landing entrance / exit 9.

[0109] In the first embodiment, the scaffolding member 22 may have a longer length in the width direction of the landing entrance 9. For example, the length of the scaffolding member 22 in the width direction of the landing entrance 9 may be the same as the length of the landing threshold 10 in the width direction of the landing entrance 9. For example, the length of the scaffolding member 22 in the width direction of the landing entrance 9 is limited by the strength of the scaffolding member 22.

[0110] In the first embodiment, the hinge 23 does not have to be attached to the landing threshold 10. In this case, for example, the hinge 23 is attached to the wall 3. Also, in this case, for example, a support member (not shown) that is fixed to the hoistway 1 and supports the landing threshold 10 from below the landing threshold 10 is provided, and the hinge 23 is attached to the support member. In addition, in the first embodiment, the height of the scaffolding member 22 in the assembled state can be changed by changing the position of the rotation axis of the hinge 23 and the shape of the slats of the hinge 23. For example, in the assembled state, the height of the upper surface of the scaffolding member 22 can be adjusted to match the height of the upper surface of the landing threshold 10. In addition, in the first embodiment, the scaffolding device 21 may include one, two, or four or more hinges 23.

[0111] In the assembled state of the first embodiment, the support rod 25 may connect the scaffolding member 22 and the upper frame 18. In this case, the length of the scaffolding member 22 in the width direction of the landing entrance 9 can be made shorter. However, when used as an entrance protection member in the stored state, the scaffolding board 22a is provided larger than the car entrance 6 in the width direction of the car entrance 6. In addition, in the assembled state of the first embodiment, the support rods 24 and 25 may connect the scaffold member 22 and the landing-door opening and closing device 12 together. Furthermore, in the assembled state of the first embodiment, the support rods 24 and 25 may connect the scaffold member 22 to the outer periphery of the opening 3a in the wall 3. In this case, for example, a fastener is provided on the outer side of the landing entrance 9 in the width direction in the wall 3, and in the assembled state, the support rods 24 and 25 are attached to the fastener.

[0112] In the first embodiment, a through-hole may be provided in the upper frame 18, and the landing device 15 may be disposed in the upper frame 18 and may face the landing 2 through the through-hole of the upper frame 18. In the first embodiment, a through-hole may be provided on the wall 3 at the side of the landing entrance 9, and the landing fixture 15 may be attached to the through-hole and face the elevator shaft 1 and the landing 2. In this case, for example, in the assembled state, the support rod 24 is attached to the wall 3.

[0113] In the assembled state of the first embodiment, the hook portion 24b may be hooked to a portion other than the reinforcing plate 16a of the vertical frame 16. In this case, for example, an eye bolt or a hook bolt is attached to the landing jamb 11, and the hook portion 24b is hooked to the eye bolt or the hook bolt. Similarly, in the assembled state of the first embodiment, the hook portion 25b may be hooked onto a portion of the vertical frame 17 other than the reinforcing plate 17a.

[0114] In the first embodiment, the through portion 22c may be provided in a portion of the scaffold member 22 other than the scaffold board 22a. For example, the reinforcing board 22b is provided longer below the scaffold board 22a, and the through portion 22c is provided on the reinforcing board 22b below the scaffold board 22a. Also, for example, the reinforcing board 22b is provided at the end of the scaffold board 22a in the width direction of the landing entrance 9, and the through portion 22c is provided on the reinforcing board 22b. In the first embodiment, the through portion 22c may be a slit that reaches the end of the scaffolding member 22.

[0115] In the assembled state of the first embodiment, it is not necessary to provide the through-hole 22c and the support rod 24 on one side of the landing entrance 9 in the width direction, or the through-hole 22c and the support rod 25 on the other side of the landing entrance 9 in the width direction. When the scaffolding device 21 is used as a scaffold for performing maintenance on the landing equipment 15 from inside the hoistway 1, it is preferable to provide the through-hole 22c and the support rod 24 on one side of the landing entrance 9 in the width direction. In addition, in the assembled state of the first embodiment, a through portion 22c and a support rod 24 or 25 may be provided in the intermediate portion of the landing entrance 9 in the width direction. In addition, in the assembled state of the first embodiment, one or more sets of the through-holes 22c and the support rods 24 or 25 may be provided. In this case, the number of the through-holes 22c and the support rods 24 or 25 can be determined according to the strength of the scaffolding member 22, for example.

[0116] In the first embodiment, the insert 26 may be provided separately from the reinforcing plate 22b. In addition, in the stored state of the first embodiment, the insertion tool 26 may extend in the depth direction and width direction of the landing entrance 9.

[0117] In the first embodiment, clamp 27 may be attached to a portion of hoistway 1 other than wall 3. In this case, for example, a support member is fixed to hoistway 1, and clamp 27 is attached to the support member.

[0118] In the first embodiment, the insert 26 may be provided in the elevator 1 , and the clamp 27 may be provided in the scaffold member 22 .

[0119] In the first embodiment, the insertion tool 26 and the clamping tool 27 on one side of the landing entrance 9 in the width direction, or the insertion tool 26 and the clamping tool 27 on the other side of the landing entrance 9 in the width direction, may not be provided. In addition, in the first embodiment, an insert 26 may be provided at the middle part of the scaffold member 22 in the width direction of the landing entrance 9, and a clamp 27 may be provided at the middle part of the wall 3 in the width direction of the landing entrance 9. Moreover, in the first embodiment, one or more sets of insert tools 26 and clamp tools 27 may be provided. In this case, for example, the number of insert tools 26 and clamp tools 27 can be determined according to the holding force with which clamp tools 27 hold insert tool 26 in a clamped state.

[0120] In the first embodiment, the scaffolding device 21 may be used in an elevator device in which one or three or more landing doors move in one direction in the width direction of the landing entrance to open and close the landing entrance.

[0121] In addition, in embodiment 1, the scaffolding device 21 may be used in an elevator system in which one or more landing doors move in one direction in the width direction of the landing entrance, and another one or more landing doors move in the other direction in the width direction of the landing entrance to open and close the landing entrance. The elevator scaffolding device 21 shown in Figures 15 and 16 is used in an elevator device in which the landing door 13 moves in one direction in the width direction of the landing entrance 9 and the landing door 14 moves in the other direction in the width direction of the landing entrance 9 to open and close the landing entrance 9. Fig. 15 is a rear view of the landing entrance 9 in a modified example of the first embodiment. Fig. 15 is a drawing corresponding to Fig. 3. Fig. 16 is a rear view of the landing entrance 9 in a modified example of the first embodiment. Fig. 16 is a drawing corresponding to Fig. 12. 15, the landing threshold 10 is provided with a groove (not shown) instead of the grooves 10a and 10b, the landing door opening / closing device 12 has a rail 12c instead of the rails 12a and 12b, and the landing doors 13 and 14 are guided in their movement in the width direction of the landing entrance 9 by the rail 12c and the groove of the landing threshold 10. In the assembled state, the support rods 24 and 25 are positioned on the side of the landing doors 13 and 14 at the fully closed position.

[0122] In addition, in embodiment 1, the side surface of wall 3 facing the elevator shaft 1 below the landing threshold 10 may be located at the same position in the depth direction of the landing entrance / exit 9 as the side surface of wall 3 facing the elevator shaft 1 above the landing threshold 10. In addition, in embodiment 1, the side of wall 3 facing hoistway 1 below landing threshold 10 may be located further outside hoistway 1 than the side of wall 3 facing hoistway 1 above landing threshold 10.

[0123] Next, the elevator scaffolding device 31 according to the second embodiment will be described with reference to Figs. 17 to 20.

[0124] FIG. 17 is a rear view of the landing entrance 9 in the second embodiment. FIG. 17 is a drawing corresponding to FIG. 3. FIG. 18 is a drawing showing the hanging device 32 and the receiving device 33 in the second embodiment. FIG. 18 is a drawing of the L part in FIG. 17. FIG. 19 is a drawing showing the hanging device 32 and the receiving device 33 in the second embodiment. FIG. 19 is a drawing viewed from the arrow MM in FIG. 18. FIG. 20 is a drawing showing the hanging device 32 and the receiving device 33 in the second embodiment. FIG. 20 is a drawing corresponding to the arrow MM in FIG. 18. FIG. 20(a) shows a state in which the hanging device 32 is moved upward by the support rod 24 in the stored state. FIG. 20(b) shows a state in which the hanging device 32 and the receiving device 33 are separated from each other in the rotation direction of the scaffold member 22 by the support rod 24 from the stored state.

[0125] The elevator scaffolding device 31 in the second embodiment does not have the insertion tool 26 and the clamping tool 27 in the elevator scaffolding device 21 in the first embodiment. The elevator scaffolding device 31 in the second embodiment has a hanger 32 and a receiver 33. The elevator scaffolding device 31 in the second embodiment has a penetration portion 22d in the scaffolding member 22. Except for the above, the elevator scaffolding device 31 in the second embodiment is the same as the elevator scaffolding device 21 in the first embodiment.

[0126] The hanging device 32 is provided on the scaffolding member 22. The hanging device 32 is attached to the scaffolding board 22a. In the assembled state, the hanging device 32 is located inside the elevator shaft 1 from the hinge 23. In the assembled state, the hanging device 32 is located on the lower side of the scaffolding member 22. In the stored state, the hanging device 32 is located below the hinge. In the stored state, the hanging device 32 is located on the wall 3 side of the scaffolding member 22. The hanging device 32 is provided on one side and the other side of the width direction of the landing entrance 9 on the scaffolding member 22. The hanging device 32 is a spring member. The hanging device 32 is a hook.

[0127] The hanging device 32 has a hook portion 32a. In the stored state, the hook portion 32a is located outside the hoistway 1 of the hanging device 32. In the stored state, the hook portion 32a is folded back to the inside of the hoistway 1 of the hanging device 32. In the stored state, the hook portion 32a protrudes downward from the hanging device 32.

[0128] The receiving device 33 is provided in the elevator shaft 1. The receiving device 33 is located below the hinge 23. The receiving device 33 is attached to the wall 3. The receiving device 33 is integral with the scaffolding member 22 and does not move. The receiving device 33 is provided on one side and the other side in the width direction of the landing entrance 9. The receiving device 33 is a hook.

[0129] The receiver 33 has a hook portion 33a. The hook portion 33a is located inside the hoistway 1 at the receiver 33. The hook portion 33a is folded back to the outside of the hoistway 1 at the receiver 33. The hook portion 33a protrudes upward from the receiver 33.

[0130] In the stored state, the hanging tool 32 and the receiving tool 33 hold the scaffolding member 22 so that the side surface of the scaffolding board 22a facing the hoistway 1 is approximately vertical. In the stored state, the hanging tool 32 is hung from the receiving tool 33 from above. In the stored state, the hook portion 32a of the hanging tool 32 and the hook portion 33a of the receiving tool 33 face each other in the depth direction of the landing entrance 9. In the stored state, the hook portion 32a of the hanging tool 32 is located closer to the wall 3 than the hook portion 33a of the receiving tool 33. In the stored state, the hanging tool 32 and the receiving tool 33 restrict the scaffolding member 22 from rotating inwardly of the hoistway 1. In the stored state, the hanging tool 32 is pushed upwardly to elastically deform, so that the hook portion 32a moves upward, and the scaffolding member 22 is allowed to rotate inwardly of the hoistway 1.

[0131] The through portion 22d penetrates the scaffolding member 22. The through portion 22d penetrates the scaffolding board 22a. The through portion 22d is a hole. In the assembled state, the through portion 22d is located inside the elevator shaft 1 relative to the hinge 23. In the stored state, the through portion 22d is located below the hinge 23. In the stored state, the through portion 22d is located below the hanger 32 of the scaffolding member 22. The through portion 22d is provided on one side and the other side of the scaffolding member 22 in the width direction of the landing entrance 9.

[0132] The hanger 32 and the receiver 33 hung on the receiver 33 in the stored state can be separated in the rotational direction of the scaffold member 22 as described below.

[0133] As shown in Figure 20, in the stored state, the hook portion 24a is lowered from the landing entrance 9 below the hoistway 1, hooked onto the hanging device 32, and moved upward, so that the hanging device 32 is pushed upward by the hook portion 24a and moves, and the hanging device 32 and the receiving device 33 move apart in the vertical direction. Furthermore, by moving the hook portion 24a toward the inside of the hoistway 1, the scaffolding member 22 is pulled toward the inside of the hoistway 1 by the hook portion 24a and rotates, and the hanging device 32 and the receiving device 33 move apart in the rotational direction of the scaffolding member 22.

[0134] For example, the hook portion 24a can be lowered from the landing entrance 9 to below the elevator shaft 1 and then passed through the penetration portion 22d of the scaffolding member 22 and moved upward, thereby being hooked onto the hanging device 32.

[0135] It should be noted that the hook portion 24b may be used instead of the hook portion 24a, and the support rod 25 may be used instead of the support rod 24.

[0136] The scaffolding member 22, hinge 23, support rods 24 and 25, hanger 32, and receiver 33 are provided as described above.

[0137] The scaffolding apparatus 31 can be switched from the stowed state to the assembled state as follows.

[0138] For example, after the hook 32 and the receiver 33 are separated from the stored state in the rotation direction of the scaffolding member 22, the hook portion 24a is lowered from the landing entrance 9 to below the hoistway 1, passed through the through-hole 22c, and moved upward to hook onto the scaffolding member 22, and then moved toward the inside of the hoistway 1, whereby the scaffolding member 22 is pulled toward the inside of the hoistway 1 by the hook portion 24a and rotates, and further the hook portion 24b is hooked onto the reinforcing plate 16a of the vertical frame 16. Similarly, the hook portion 25a is hooked onto the scaffolding member 22, and the support rod 25 is hooked onto the reinforcing plate 17a of the vertical frame 17, whereby the scaffolding member 22 is in the assembled state.

[0139] The procedure for switching from the assembled state to the stored state is the reverse of the procedure for switching from the stored state to the assembled state.

[0140] When switching from the assembled state to the stored state, the hanging device 32 can be hung on the receiving device 33 without using the support rods 24 and 25. For example, after the support rods 24 and 25 are removed, the scaffolding member 22 rotates by its own weight, and the hanging device 32 is hung on the receiving device 33.

[0141] The elevator scaffolding device 31 in the second embodiment is provided as described above.

[0142] The elevator scaffolding device 31 in embodiment 2 is equipped with a hanger 32 and a receiver 33, one of the hanger 32 and the receiver 33 being provided on the scaffolding member 22 and the other of the hanger 32 and the receiver 33 being provided in the hoistway 1, and in the stored state, the hanger 32 is hung from above on the receiver 33, thereby restricting the rotation of the scaffolding member 22 inwardly into the hoistway 1.

[0143] As a result, when the elevator device is in operation, the hangers 32 and the receivers 33 can prevent the scaffolding members 22 from rotating from the stored state toward the inside of the hoistway 1 and hitting the car 5. For example, it is possible to prevent the scaffolding members 22 from rotating toward the inside of the hoistway 1 due to wind pressure generated by the car 5 ascending and descending, an updraft generated in the hoistway 1 in winter due to the temperature difference between the inside and outside of the building in which the elevator device is installed, shaking of the building in which the elevator device is installed, and the like.

[0144] In the elevator scaffolding device 31 in the second embodiment, when the hanging device 32 is pushed upward, the hanging device 32 elastically deforms and moves upward, and the scaffolding member 22 is allowed to rotate inwardly of the hoistway 1.

[0145] This allows the structure of the hanger 32 to be simplified.

[0146] In the elevator scaffolding device 31 of embodiment 2, the support bar 24 has a hook portion 24a at one longitudinal end, and in the stored state, the hook portion 24a is lowered from the landing entrance 9 below the hoistway 1 and hooked onto the hanging device 32 and moved upward, causing the hanging device 32 to move upward, and by further moving the hook portion 24a toward the inside of the hoistway 1, the scaffolding member 22 is pulled toward the inside of the hoistway 1 by the hook portion 24a and rotates, and the hanging device 32 and the receiving device 33 move apart in the rotational direction of the scaffolding member 22.

[0147] This allows the worker to separate the hanging device 32 and the receiving device 33 in the rotation direction of the scaffolding member 22 using the support rod 24 from the landing entrance / exit 9.

[0148] Similarly, a worker can separate the hanging device 32 and the receiving device 33 in the rotation direction of the scaffolding member 22 by using the support rod 25 from the landing entrance 9.

[0149] In the second embodiment, the hanging device 32 does not have to be a spring member. In this case, for example, the hanging device 32 is attached to the scaffolding board 22a so as to be rotatable about a rotation axis oriented in the width direction of the landing entrance 9, and the hanging device 32 rotates when pushed upward, and the hook portion 32a moves upward. In the second embodiment, the hanging device 32 may be attached to a portion other than the scaffolding board 22a of the scaffolding member 22. In this case, for example, the hanging device 32 is attached to the reinforcing board 22b.

[0150] In the second embodiment, the through-holes 22d may be slits that reach the ends of the scaffolding members 22. Also, in the second embodiment, the through-hole portion 22d may not be provided. In this case, for example, the hanging device 32 is provided at the lower end of the scaffolding member 22 in the vertical direction, and when the hanging device 32 and the receiving device 33 are separated in the depth direction of the landing entrance 9, the hook portion 24a or 25a is moved from below the scaffolding member 22 to above, so as to be hooked onto the hanging device 32. Also, for example, the hanging device 32 is provided at the side end of the scaffolding member 22 in the width direction of the landing entrance 9, and when the hanging device 32 and the receiving device 33 are separated in the depth direction of the landing entrance 9, the hook portion 24a or 25a is disposed below the hanging device 32 from the side of the scaffolding member 22, and is moved upward, so as to be hooked onto the hanging device 32.

[0151] In the second embodiment, the hanging device 32 may be attached to a portion other than the scaffolding board 22a of the scaffolding member 22. In this case, for example, the hanging device 32 is attached to the reinforcing board 22b.

[0152] In the second embodiment, the receiver 33 may be attached to a portion of the hoistway 1 other than the wall 3. In this case, for example, a support member is fixed to the hoistway 1, and the receiver 33 is attached to the support member.

[0153] In the second embodiment, the receiver 33 does not have to have the hook portion 33a. In this case, for example, the receiver 33 may have a hole that opens upward, and the hook portion 32a of the hanger 32 may be inserted into the hole from above in the stored state to hang the hanger 32.

[0154] In the second embodiment, the hanger 32 may be provided in the elevator 1 , and the receiver 33 may be provided in the scaffold member 22 .

[0155] In addition, in the second embodiment, it is not necessary to provide the through-hole 22d, the hanging device 32, and the receiving device 33 on one side of the landing entrance 9 in the width direction, or the through-hole 22d, the hanging device 32, and the receiving device 33 on the other side of the landing entrance 9 in the width direction. In the second embodiment, a hanger 32 may be provided at the middle of the width direction of the landing entrance 9 on the scaffold member 22, and a receiver 33 may be provided at the middle of the width direction of the landing entrance 9 on the wall 3. Furthermore, in the second embodiment, three or more sets of the through-holes 22d, the hangers 32, and the receivers 33 may be provided. In this case, for example, the number of the hangers 32 and the receivers 33 can be determined according to the holding force for holding the state in which the hangers 32 are hung on the receivers 33.

[0156] Next, an elevator scaffolding device 41 according to the third embodiment will be described with reference to Figs. 21 to 24.

[0160] The support base 42 is provided in the hoistway 1. The support base 42 is attached to a wall 4. The wall 4 is located on one side of the landing entrance 9 in the width direction of the hoistway 1 relative to the landing entrance 9. The wall 4 extends in the depth direction and in the up-down direction of the landing entrance 9. The support base 42 is disposed away from the scaffold member 22 on one side of the landing entrance 9 in the width direction. The support base 42 protrudes from the wall 4 to the inside of the hoistway 1.

[0161] In the assembled state, the scaffold extension members 43 are attached as follows.

[0162] The scaffold extension member 43 connects the scaffold member 22 and the support base 42. The scaffold extension member 43 is detachably attached to the scaffold member 22 and the support base 42. One end 43a of the scaffold extension member 43 is placed on the scaffold member 22. The other end 43b of the scaffold extension member 43 is placed on the support base 42.

[0163] The scaffold extension member 43 has one end 43a disposed closer to the landing entrance 9 than the support rod 24 in the depth direction of the landing entrance 9. The one end 43a faces the support rod 24 in the depth direction of the landing entrance 9.

[0164] The scaffold extension member 43 has a pair of protrusions 43c. The protrusions 43c are located at one end 43a. The protrusions 43c protrude downward from the scaffold extension member 43. The protrusions 43c are pins. The protrusions 43c are passed through the through-holes 22e of the scaffold member 22.

[0165] In the stored state, the scaffold extension member 43 does not connect the scaffold member 22 and the support base 42. In the stored state, the scaffold extension member 43 is handled as follows.

[0166] For example, the scaffolding extension member 43 is stored in a manager's room, a disaster prevention center, or the like provided in the building in which the scaffolding device 41 is installed. Also, for example, the scaffolding extension member 43 is attached to the elevator shaft 1 side of the side of the landing entrance 9 in the wall 3. Also, for example, the scaffolding extension member 43 is attached to the wall 3 side of the scaffolding member 22.
