[0093] The insert 26 is provided in the scaffolding member 22. The insert 26 is mounted on the scaffolding plate 22a. The insert 26 is a plate-shaped member. The insert 26 extends in the depth direction and the up-down direction of the landing entrance 9. In the assembled state, the insert 26 is located at a position closer to the inner side of the shaft 1 than the hinge 23. In the assembled state, the insert 26 is located at the lower side of the scaffolding member 22. In the stored state, the insert 26 is located at a position lower than the hinge 23. In the stored state, the insert 26 is located on the wall 3 side of the scaffolding member 22. The insert 26 is provided on one side and the other side of the width direction of the landing entrance 9 of the scaffolding member 22. The insert 26 is a reinforcing plate 22b.

[0094] The clamp 27 is provided in the hoistway 1. The clamp 27 is located below the hinge 23. The clamp 27 is mounted on the wall 3. The clamp 27 is integral with the scaffolding member 22 and does not move. The clamp 27 is provided on one side and the other side in the width direction of the landing entrance 9. The clamp 27 is a spring member. The clamp 27 is a clip.

[0095] In the stored state, the insert 26 and the clamp 27 hold the scaffolding member 22 in such a manner that the side surface of the inner side of the shaft 1 of the scaffolding plate 22a becomes approximately vertical. In the stored state, the insert 26 is clamped by the clamp 27. In the stored state, the insert 26 is inserted into the clamp 27 along the rotation direction of the scaffolding member 22. In the stored state, the insert 26 is inserted into the clamp 27 along the depth direction of the landing entrance 9. In the stored state, the clamp 27 is elastically bent in the width direction of the landing entrance 9. In the stored state, the insert 26 is pressed by the clamp 27 by the elastic force of the clamp 27. In the stored state, the scaffolding member 22 is restrained from rotating by the insert 26 and the clamp 27.

[0096] The inserting member 26 and the clamping member 27 clamped by the clamping member 27 in the stored state can be separated in the rotation direction of the scaffold member 22 as described below.

[0097] like Fig.11 As shown, in the stored state, the hook 24a is lowered from the floor station entrance 9 to the bottom of the shaft 1, and is hooked on the scaffolding component 22, and is moved toward the inside of the shaft 1, thereby, the scaffolding component 22 is pulled toward the inside of the shaft 1 by the hook 24a and rotated, and the insert 26 and the clamp 27 are separated in the rotation direction of the scaffolding component 22.

[0098] For example, the hook 24a is lowered from the landing entrance 9 to the bottom of the shaft 1, and moves upward through the through portion 22c of the scaffolding member 22, thereby being hooked on the scaffolding member 22. In addition, for example, the hook 24a is lowered from the landing entrance 9 to the bottom of the shaft 1, and moves upward from the bottom of the scaffolding member 22, thereby being hooked on the scaffolding member 22.

[0099] In a state where the hook 24a is hooked on the scaffolding member 22, the side of the support rod 24 opposite to the hook 24a can be located on the upper part of the landing sill 10. For example, after the hook 24a is hooked on the scaffolding member 22, the middle part of the support rod 24 is brought into contact with the landing sill 10, and the side of the support rod 24 opposite to the hook 24a is moved toward the landing entrance 9, thereby the hook 24a moves toward the inside of the shaft 1. In addition, for example, after the hook 24a is hooked on the scaffolding member 22, the side of the support rod 24 opposite to the hook 24a is arranged at a position closer to the inside of the shaft 1 than the hook 24a in the depth direction of the landing entrance 9, and the support rod 24 is pulled along the length direction of the support rod 24, thereby the hook 24a moves toward the inside of the shaft 1.

[0100] Here, the hook portion 24 b may be used instead of the hook portion 24 a. In addition, the support rod 25 may be used instead of the support rod 24 .

[0101] The frame part 22, the hinge 23, the support rods 24 and 25, the insert 26 and the clamp 27 are arranged as described above.

[0102] The scaffold device 21 can be switched from the stored state to the assembled state as described below.

[0103] For example, after the insert 26 and the clamp 27 are separated in the rotation direction of the scaffolding member 22 from the storage state, the hook 24a is lowered from the landing entrance 9 to the bottom of the shaft 1, and moves upward through the through portion 22c, thereby hooking the scaffolding member 22, and moving to the inside of the shaft 1, thereby the scaffolding member 22 is pulled to the inside of the shaft 1 by the hook 24a and rotated, and then the hook 24b is hooked to the reinforcing plate 16a of the longitudinal frame 16. Similarly, the hook 25a is hooked to the scaffolding member 22, and the support rod 25 is hooked to the reinforcing plate 17a of the longitudinal frame 17, thereby the scaffolding member 22 is assembled.

[0104] The order of switching from the assembled state to the stored state is the reverse order of the order of switching from the stored state to the assembled state.

[0105] Furthermore, 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 due to its own weight, and the insert 26 is inserted into the clamp 27.

[0106] The scaffold device 21 of the elevator in Embodiment 1 is installed as described above.

[0107] When the scaffolding device 21 is switched from the stored state to the assembled state, appropriate measures are taken to prevent the scaffolding device 21 from falling from the opened landing doorway 9. For example, a fence or a handrail is provided between the vertical frames 16 and 17.

[0108] In addition, when the scaffolding device 21 is switched from the storage state to the assembly state, appropriate measures are taken to prevent the opened landing entrance 9 from being accidentally closed. For example, when the landing entrance 9 is opened, a wedge is inserted into the fully closed position side of the landing doors 13 and 14 in the grooves 10a and 10b of the landing sill 10.

[0109] In addition, after the scaffolding device 21 is switched from the stored state to the assembled state, appropriate measures are taken to prevent it from falling from the scaffolding member 22. For example, a fence or a handrail is provided along the edge of the scaffolding member 22. In this case, the fence or the handrail can be installed on the scaffolding member 22, the support rods 24 and 25, the landing three-square frame 11, etc.

[0110] The scaffolding device 21 of the elevator in the first embodiment is provided in the elevator device, and is switched between an assembled state and a stored state, wherein the assembled state is a state in which a scaffolding connected to the landing entrance and exit 9 is formed in the hoistway, and the stored state is a state in which an entrance and exit protection component of the landing entrance and exit 9 is formed in the hoistway, wherein the scaffolding device 21 of the elevator includes a scaffolding component 22, a hinge 23, and support rods 24 and 25, wherein the hinge 23 is provided at a position lower than the landing entrance and exit 9, and the rotating shaft 23a of the hinge 23 is oriented toward the landing entrance and exit 9. In the width direction, the scaffolding component 22 is installed on the hinge 23, and is switched between the assembled state and the stored state by rotating around the rotating shaft 23a. In the assembled state, the scaffolding component 22 extends from the hinge 23 on the inner side of the shaft 1 along the width direction and the depth direction of the floor station entrance 9, and the support rods 24 and 25 connect the scaffolding component 22 to the outer periphery of the floor station entrance 9 above the scaffolding component 22. In the stored state, the scaffolding component 22 extends from the hinge 23 at the bottom along the width direction and the up and down direction of the floor station entrance 9.

[0111] Thus, when a worker goes back and forth between the scaffold in the hoistway 1 formed by the scaffold device 21 and the landing doorway 9 , there is no need to descend to the hoistway pit that is the bottom of the hoistway 1 .

[0112] In addition, the operator can install a scaffold in the hoistway 1 without erecting a step stool at the bottom of the hoistway 1 .

[0113] Furthermore, regardless of the depth from the landing doorway 9 to the bottom of the hoistway 1 , the worker can use the scaffolding device 21 .

[0114] In addition, the scaffold member 22 can be accommodated in the space where the entrance and exit protection member is provided.

[0115] In addition, the operator can hook the hook of the seat belt on the support member 24 or 25 .

[0116] In addition, it is effective to provide a scaffolding device 21 that communicates with the landing entrance 9 of the lowest landing 2 among the multiple landings 2 where the car 5 stops. In many elevator devices, it is difficult to move from the landing entrance 9 of the lowest landing 2 to the upper part of the car 5. The car 5 is restricted from descending in a manner that it does not contact the equipment at the bottom of the hoistway 1.

[0117] The scaffolding device 21 of the elevator in embodiment 1 is arranged in the following elevator device: when the elevator device is running, the floor station doors 13 and 14 move between the fully closed position and the fully open position, thereby the floor station entrance and exit 9 opens and closes between the fully closed state and the fully open state. In the assembled state, the floor station entrance and exit 9 is open, and the support rods 24 and 25 are located on the fully closed position side of the floor station doors 13 and 14.

[0118] Thus, in the assembled state, the landing doors 13 and 14 are held by the support rods 24 and 25 to open the landing entrance 9 , so that the operator can easily move back and forth between the scaffold in the hoistway 1 formed by the scaffold device 21 and the landing entrance 9 .

[0119] The elevator scaffolding device 21 in Embodiment 1 is provided in an elevator device that detects whether the landing entrance 9 is fully closed by the landing entrance switch, and does not raise or lower the car 5 when the landing entrance switch does not detect that the landing entrance 9 is fully closed.

[0120] Thereby, in the assembled state, it is possible to prevent the car 5 from being raised or lowered and colliding with the scaffolding device 21 .

[0121] The scaffolding device 21 of the elevator in embodiment 1 is arranged in the following elevator device: the side and upper parts of the landing entrance and exit 9 are formed by the landing three-square frame 11, and in the assembled state, the support rods 24 and 25 connect the scaffolding parts 22 to the landing three-square frame 11.

[0122] Thus, regardless of the structure of the hoistway 1 , the support rods 24 and 25 can be easily attached to the outer peripheral portion of the landing doorway 9 above the scaffold member 22 .

[0123] The scaffolding device 21 of the elevator in embodiment 1 is arranged in the following elevator device: the floor station entrance and exit 9 is opened and closed by moving the floor station doors 13 and 14 in the width direction of the floor station entrance and exit 9. When maintaining the elevator device, the floor station doors 13 and 14 can be opened larger than the fully open position. In the assembled state, the floor station doors 13 and 14 are opened larger than the fully open position. The support rod 24 is installed on the shaft 1 side of the longitudinal frame 16 of the side portion of the floor station three-square frame 11 constituting the floor station entrance and exit 9, and the support rod 25 is installed on the shaft 1 side of the longitudinal frame 17 of the side portion of the floor station three-square frame 11 constituting the floor station entrance and exit 9.

[0124] Thereby, the worker can easily attach the support rods 24 and 25 to the landing three-square frame 11 from the landing doorway 9 .

[0125] The scaffolding device 21 of the elevator of embodiment 1 is arranged in the following elevator device: a floor station equipment 15 is installed on the longitudinal frame 16, and the floor station equipment 15 can be maintained from the side of the shaft 1. In the assembled state, the scaffolding component 22 is located below the floor station equipment 15, and the support rod 24 is located at a position closer to the outside of the floor station entrance and exit 9 than the floor station equipment 15.

[0126] Thereby, the operator can perform maintenance of the landing equipment 15 from the hoistway 1 side without being hindered by the support rod 24 .

[0127] The elevator scaffold device 21 in the first embodiment is provided in an elevator device in which the lower portion of a landing doorway 9 is formed by a landing sill 10 and the hinge 23 is attached to the landing sill 10 .

[0128] Thereby, regardless of the structure of the hoistway 1 , the hinge 23 can be easily provided at a position below the landing doorway 9 .

[0129] In the scaffolding device 21 of the elevator of embodiment 1, the support rod 24 has a hook portion 24a at one end in the length direction. In the stored state, the scaffolding component 22 can be rotated toward the inside of the shaft 1 by hooking the hook portion 24a from the floor station entrance 9 and moving it toward the inside of the shaft 1, and then the other end of the support rod 24 is installed on the outer periphery of the floor station entrance 9 above the scaffolding component 22, so that it can be put into an assembled state.

[0130] Thus, the operator can switch between the stored state and the assembled state using the support rod 24 from the landing doorway 9 .

[0131] Similarly, the operator can switch between the stored state and the assembled state using the support rod 25 from the landing doorway 9 .

[0132] In the scaffolding device 21 of the elevator in embodiment 1, there are an insert 26 and a clamp 27, one of which is set on the scaffolding part 22, and the other of which is set on the hoistway 1. In the stored state, the insert 26 is inserted into the clamp 27 in the rotation direction of the scaffolding part 22, thereby suppressing the rotation of the scaffolding part 22.

[0133] Thus, when the elevator device is in operation, the insert 26 and the clamp 27 can be used to prevent the scaffolding member 22 from rotating from the stored state to the inside of the shaft 1 and hitting the car 5. For example, the scaffolding member 22 can be prevented from rotating to the inside of the shaft 1 due to wind pressure generated by the lifting and lowering of the car 5, the rising airflow in the shaft 1 due to the temperature difference between the inside and outside of the building where the elevator device is installed in winter, and the shaking of the building where the elevator device is installed.

[0134] In the elevator scaffold device 21 of the first embodiment, the insert 26 is a reinforcing plate 22 b provided on the scaffold member 22 , and the reinforcing plate 22 b is provided across the scaffold member 22 on the hinge 23 side and the side opposite to the hinge 23 .

[0135] Thus, there is no need to separately provide the reinforcing plate 22b and the insert 26.

[0136] In the scaffolding device 21 of the elevator of embodiment 1, the support rod 24 has a hook portion 24a at one end in the length direction. In the storage state, the hook portion 24a is lowered from the floor station entrance 9 to the bottom of the shaft 1, and is hooked on the scaffolding component 22 and moved toward the inside of the shaft 1, thereby the scaffolding component 22 is pulled toward the inside of the shaft 1 by the hook portion 24a and rotated, and the insert 26 and the clamp 27 are separated in the rotation direction of the scaffolding component 22.

[0137] Thus, the operator can separate the inserting tool 26 and the clamping tool 27 from the landing doorway 9 by using the support rod 24 in the rotation direction of the scaffold member 22 .

[0138] Similarly, the operator can separate the inserting tool 26 and the clamping tool 27 in the rotation direction of the scaffold member 22 from the landing doorway 9 using the support rod 25 .

[0139] In the first embodiment, the length of the scaffolding member 22 in the width direction of the landing entrance 9 can be made longer. For example, the length of the scaffolding member 22 in the width direction of the landing entrance 9 can be set to the same length as the length of the landing sill 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.

[0140] In addition, in Embodiment 1, the hinge 23 may not be attached to the landing sill 10. In this case, for example, the hinge 23 is attached to the wall 3. In this case, for example, a support member (not shown) fixed to the hoistway 1 and supporting the landing sill 10 from below the landing sill 10 is provided, and the hinge 23 is attached to the support member.

[0141] 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 hinge plate of the hinge 23. For example, in the assembled state, the height of the upper surface of the scaffolding member 22 can be made consistent with the height of the upper surface of the landing sill 10.

[0142] In addition, in the first embodiment, the scaffold device 21 may include one, two, or four or more hinges 23 .

[0143] In the assembled state of the first embodiment, the support rod 25 may connect the scaffolding member 22 to 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 plate 22a is set larger than the car entrance 6 in the width direction of the car entrance 6.

[0144] In addition, in the assembled state of the first embodiment, the support rods 24 and 25 may connect the scaffolding member 22 and the landing door opening and closing device 12 .

[0145] In addition, in the assembled state of the first embodiment, the support rods 24 and 25 may connect the scaffolding member 22 to the outer periphery of the opening 3a of the wall 3. In this case, for example, a fixing is provided on the outer side of the width direction of the landing entrance 9 of the wall 3, and in the assembled state, the support rods 24 and 25 are attached to the fixing.

[0146] Furthermore, in Embodiment 1, a through portion may be provided in the upper frame 18 , and the landing equipment 15 may be arranged in the upper frame 18 and pass through the through portion of the upper frame 18 to face the landing 2 .

[0147] In the first embodiment, a through portion may be provided on the side of the landing entrance 9 of the wall 3, and the landing equipment 15 may be mounted on the through portion and face the hoistway 1 and the landing 2. In this case, for example, the support rod 24 is mounted on the wall 3 in the assembled state.

[0148] In the assembled state of Embodiment 1, the hook 24b may be hooked to a portion other than the reinforcing plate 16a of the vertical frame 16. In this case, for example, an eyebolt or a hook bolt is installed on the landing three-way frame 11, and the hook 24b is hooked to the eyebolt or the hook bolt.

[0149] Similarly, in the assembled state of the first embodiment, the hook portion 25 b may be hooked on a portion of the vertical frame 17 other than the reinforcing plate 17 a .

[0150] In the first embodiment, the through-portion 22c may be provided at a portion other than the scaffolding plate 22a of the scaffolding member 22. For example, the reinforcing plate 22b is provided longer downward than the scaffolding plate 22a, and the through-portion 22c is provided at a position of the reinforcing plate 22b lower than the scaffolding plate 22a. In addition, for example, the reinforcing plate 22b is provided at the end of the scaffolding plate 22a in the width direction of the landing entrance 9, and the through-portion 22c is provided at the reinforcing plate 22b.

[0151] In the first embodiment, the through portion 22 c may be a slit reaching the end of the scaffold member 22 .

[0152] In addition, in the assembled state of embodiment 1, it is also possible not to have the through-portion 22c and the support rod 24 located on one side of the width direction of the landing entrance 9, or the through-portion 22c and the support rod 25 located on the other side of the width direction of the landing entrance 9. When the scaffolding device 21 is used as a scaffold for maintenance of the landing equipment 15 from the hoistway 1, it is preferably provided with the through-portion 22c and the support rod 24 located on one side of the width direction of the landing entrance 9.

[0153] In the assembled state of the first embodiment, the through portion 22 c and the support rod 24 or 25 may be provided in the middle portion in the width direction of the landing doorway 9 .

[0154] In the assembled state of Embodiment 1, one or more sets of through-holes 22c and support rods 24 or 25 may be provided. In this case, the number of through-holes 22c and support rods 24 or 25 is determined according to the strength of the scaffold member 22, for example.

[0155] In the first embodiment, the insert 26 may be provided separately from the reinforcing plate 22b.

[0156] Furthermore, in the stored state of the first embodiment, the inserting member 26 may be extended in the depth direction and the width direction of the landing doorway 9 .

[0157] Furthermore, in Embodiment 1, the clamp 27 may be attached to a portion other than the wall 3 in the hoistway 1. In this case, for example, a support member is fixed to the hoistway 1, and the clamp 27 is attached to the support member.

[0158] In the first embodiment, the inserting tool 26 may be provided in the hoistway 1 , and the clamping tool 27 may be provided in the scaffold member 22 .

[0159] In the first embodiment, the inserting piece 26 and the clamping piece 27 on one side in the width direction of the landing doorway 9 or the inserting piece 26 and the clamping piece 27 on the other side in the width direction of the landing doorway 9 may not be provided.

[0160] In the first embodiment, the inserting member 26 may be provided at the middle portion of the scaffold member 22 in the width direction of the landing entrance 9 , and the clamping member 27 may be provided at the middle portion of the wall 3 in the width direction of the landing entrance 9 .

[0161] In Embodiment 1, one or three or more sets of inserts 26 and clamps 27 may be provided. In this case, the number of inserts 26 and clamps 27 is determined based on the holding force of the clamps 27 holding the inserts 26, for example.

[0162] Furthermore, in Embodiment 1, the scaffold 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 doorway to open and close the landing doorway.

[0163] In addition, in embodiment 1, the scaffolding device 21 can also be used for an elevator device as follows: one or more landing doors move in one direction of the width direction of the landing entrance and exit, and one or more other landing doors move in another direction of the width direction of the landing entrance and exit to open and close the landing entrance and exit.

[0164] Fig.15 and Fig.16 The elevator scaffolding device 21 shown is used for an elevator device in which the landing door 13 moves in one direction of the width direction of the landing entrance 9 and the landing door 14 moves in the other direction of the width direction of the landing entrance 9 to open and close the landing entrance 9.

[0165] Fig.15 This is a rear view of the landing doorway 9 in the modified example of the first embodiment. Fig.15 is equivalent to Figure 3 . Fig.16 This is a rear view of the landing doorway 9 in the modified example of the first embodiment. Fig.16 is equivalent to Fig.12 .

[0166] exist Fig.15 In the embodiment, the landing sill 10 is provided with a groove (not shown) instead of the grooves 10a and 10b, and the landing door opening and closing device 12 has a track 12c instead of the tracks 12a and 12b, and the movement of the landing doors 13 and 14 in the width direction of the landing entrance 9 is guided by the track 12c and the groove of the landing sill 10. In addition, in the assembled state, the support rods 24 and 25 are located on the fully closed position side of the landing doors 13 and 14.

[0167] In the first embodiment, the side surface of the wall 3 on the hoistway 1 side below the landing sill 10 may be located at the same position in the depth direction of the landing doorway 9 as the side surface of the wall 3 on the hoistway 1 side upward from the landing sill 10 .

[0168] In the first embodiment, the side surface of the wall 3 on the hoistway 1 side below the landing sill 10 may be located outside the hoistway 1 than the side surface of the wall 3 on the hoistway 1 side above the landing sill 10 .

[0169] Next, use Figures 17 to 20 The scaffold device 31 of the elevator according to the second embodiment will be described.

[0170] Fig.17 This is a rear view of the landing doorway 9 in the second embodiment. Fig.17 is equivalent to Figure 3 . Fig.18 This is a diagram showing a hook member 32 and a receiving member 33 in the second embodiment. Fig.18 yes Fig.17 Figure 2 shows the L part of the graph. Fig.19 This is a diagram showing a hook member 32 and a receiving member 33 in the second embodiment. Fig.19 yes Fig.18 MM view in the figure.

Fig. 20 (a) shows a state where the hook member 32 is moved upward by the support rod 24 in the stored state. Fig. 20 (b) shows a state where the hook member 32 and the receiving member 33 are separated from each other in the rotation direction of the scaffold member 22 by the support rod 24 from the stored state.

[0171] The elevator scaffold device 31 in the second embodiment does not include the inserting member 26 and the clamping member 27 of the elevator scaffold device 21 in the first embodiment. The elevator scaffold device 31 in the second embodiment includes a hooking member 32 and a receiving member 33. The elevator scaffold device 31 in the second embodiment has a through portion 22d in the scaffold member 22. Except for this, the elevator scaffold device 31 in the second embodiment is the same as the elevator scaffold device 21 in the first embodiment.

[0172] The hook member 32 is provided on the scaffolding member 22. The hook member 32 is mounted on the scaffolding board 22a. In the assembled state, the hook member 32 is located at a position closer to the inside of the shaft 1 than the hinge 23. In the assembled state, the hook member 32 is located at the lower side of the scaffolding member 22. In the stored state, the hook member 32 is located at a position lower than the hinge. In the stored state, the hook member 32 is located on the wall 3 side of the scaffolding member 22. The hook member 32 is provided on one side and the other side of the width direction of the landing entrance 9 of the scaffolding member 22. The hook member 32 is a spring member. The hook member 32 is a hook.

[0173] The hook member 32 has a hook portion 32a. In the stored state, the hook portion 32a is located outside the shaft 1 of the hook member 32. In the stored state, the hook portion 32a is folded back to the inside of the shaft 1 of the hook member 32. In the stored state, the hook portion 32a protrudes downward of the hook member 32.

[0174] The receiving member 33 is provided in the hoistway 1. The receiving member 33 is located below the hinge 23. The receiving member 33 is mounted on the wall 3. The receiving member 33 is integral with the scaffold member 22 and does not move. The receiving member 33 is provided on one side and the other side in the width direction of the landing entrance 9. The receiving member 33 is a hook.

[0175] The socket 33 has a hook portion 33a. The hook portion 33a is located inside the hoistway 1 of the socket 33. The hook portion 33a is folded back toward the outside of the hoistway 1 of the socket 33. The hook portion 33a protrudes upward from the socket 33.

[0176] In the stored state, the hook member 32 and the receiving member 33 hold the scaffolding member 22 in such a manner that the side surface of the inner side of the shaft 1 of the scaffolding plate 22a becomes substantially vertical. In the stored state, the hook member 32 is hooked on the receiving member 33 from above. In the stored state, the hook portion 32a of the hook member 32 and the hook portion 33a of the receiving member 33 are opposed in the depth direction of the floor station entrance 9. In the stored state, the hook portion 32a of the hook member 32 is located at a position closer to the wall 3 side than the hook portion 33a of the receiving member 33. In the stored state, the rotation of the scaffolding member 22 to the inner side of the shaft 1 is restricted by the hook member 32 and the receiving member 33. In the stored state, the hook member 32 is pressed upward and elastically deformed, the hook portion 32a moves upward, and the rotation of the scaffolding member 22 to the inner side of the shaft 1 is allowed.

[0177] The through portion 22d penetrates the scaffolding member 22. The through portion 22d penetrates the scaffolding plate 22a. The through portion 22d is a hole. In the assembled state, the through portion 22d is located at a position closer to the inside of the shaft 1 than the hinge 23. In the stored state, the through portion 22d is located at a position lower than the hinge 23. In the stored state, the through portion 22d is located below the hook 32 of the scaffolding member 22. The through portion 22d is provided on one side and the other side of the width direction of the landing entrance 9 of the scaffolding member 22.

[0178] The hook member 32 hooked on the receiving member 33 in the stored state and the receiving member 33 can be separated in the rotation direction of the scaffold member 22 as described below.

[0179] like Fig. 20 As shown, in the stored state, the hook 24a is lowered from the floor station entrance 9 to the bottom of the shaft 1, and is hooked on the hook member 32 and moved upward, thereby, the hook member 32 is pressed upward by the hook 24a and moves, and the hook member 32 and the receiving member 33 are separated in the up and down directions, and then the hook 24a is moved toward the inner side of the shaft 1, thereby, the scaffolding component 22 is pulled toward the inner side of the shaft 1 by the hook 24a and rotated, and the hook member 32 and the receiving member 33 are separated in the rotation direction of the scaffolding component 22.

[0180] For example, the hook 24 a is lowered from the landing doorway 9 to the bottom of the hoistway 1 , and is moved upward through the through portion 22 d of the scaffold member 22 , so that the hook 24 a can be hooked on the hooking tool 32 .

[0181] In addition, the hook part 24b may be used instead of the hook part 24a. In addition, the support rod 25 may be used instead of the support rod 24.

[0182] The scaffolding member 22, the hinge 23, the supporting rods 24 and 25, the hook member 32, and the receiving member 33 are arranged as described above.

[0183] The scaffold device 31 can be switched from the stored state to the assembled state as described below.

[0184] For example, after the hook 32 and the receiving member 33 are separated in the rotation direction of the scaffolding member 22 from the storage state, the hook 24a is lowered from the landing entrance 9 to the bottom of the shaft 1, and moves upward through the through portion 22c, thereby hooking the scaffolding member 22, and moving to the inside of the shaft 1, thereby the scaffolding member 22 is pulled to the inside of the shaft 1 by the hook 24a and rotated, and then the hook 24b is hooked to the reinforcing plate 16a of the longitudinal frame 16. Similarly, the hook 25a is hooked to the scaffolding member 22, and the support rod 25 is hooked to the reinforcing plate 17a of the longitudinal frame 17, thereby the scaffolding member 22 is assembled.

[0185] The order of switching from the assembled state to the stored state is the reverse order of the order of switching from the stored state to the assembled state.

[0186] In addition, when switching from the assembled state to the stored state, the hook member 32 can be hooked on the receiving member 33 without using the support rods 24 and 25. For example, after the support rods 24 and 25 are removed, the scaffold member 22 rotates due to its own weight, and the hook member 32 is hooked on the receiving member 33.

[0187] The scaffold device 31 of the elevator in the second embodiment is installed as described above.

[0188] In the scaffolding device 31 of the elevator in embodiment 2, there are a hook member 32 and a receiving member 33, one of the hook member 32 and the receiving member 33 is set on the scaffolding component 22, and the other of the hook member 32 and the receiving member 33 is set in the shaft 1. In the stored state, the hook member 32 is hooked on the receiving member 33 from above, thereby restricting the rotation of the scaffolding component 22 toward the inside of the shaft 1.

[0189] Thus, when the elevator device is in operation, the hook member 32 and the receiving member 33 can prevent the scaffolding member 22 from rotating toward the inside of the shaft 1 from the stored state and hitting the car 5. For example, the scaffolding member 22 can be prevented from rotating toward the inside of the shaft 1 due to wind pressure generated by the lifting and lowering of the car 5, the rising airflow generated in the shaft 1 due to the temperature difference between the inside and outside of the building where the elevator device is installed in winter, and the shaking of the building where the elevator device is installed.

[0190] In the elevator scaffold device 31 of the second embodiment, by pressing the hook 32 upward, the hook 32 is elastically deformed and moved upward, and the rotation of the scaffold member 22 toward the inside of the hoistway 1 is allowed.

[0191] Thereby, the structure of the hook member 32 can be simplified.

[0192] In the scaffolding device 31 of the elevator of embodiment 2, the support rod 24 has a hook portion 24a at one end in the length direction. In the storage state, the hook portion 24a is lowered from the floor station entrance 9 to the bottom of the shaft 1, and is hooked on the hook member 32 and moves upward, thereby the hook member 32 moves upward, and then the hook portion 24a moves toward the inside of the shaft 1, thereby the scaffolding component 22 is pulled by the hook portion 24a toward the inside of the shaft 1 and rotates, and the hook member 32 and the receiving member 33 are separated in the rotation direction of the scaffolding component 22.

[0193] Thereby, the worker can separate the hooking member 32 and the receiving member 33 in the rotation direction of the scaffold member 22 by using the support rod 24 from the landing doorway 9 .

[0194] Similarly, the worker can separate the hooking member 32 and the receiving member 33 in the rotation direction of the scaffold member 22 by using the support rod 25 from the landing doorway 9 .

[0195] In Embodiment 2, the hook member 32 may not be a spring member. In this case, for example, the hook member 32 is mounted on the scaffolding plate 22a so as to be rotatable about a rotation axis in the width direction of the landing entrance 9, and the hook member 32 is pressed upward to rotate, and the hook portion 32a moves upward.

[0196] In the second embodiment, the hook 32 may be attached to a portion other than the scaffolding plate 22a of the scaffolding member 22. In this case, for example, the hook 32 is attached to the reinforcing plate 22b.

[0197] In the second embodiment, the through portion 22 d may be a slit reaching the end of the scaffold member 22 .

[0198] In the second embodiment, the through-portion 22d may not be provided. In this case, for example, the hook member 32 is provided at the lower end of the scaffold member 22 in the vertical direction, and when the hook member 32 and the receiving member 33 are separated in the depth direction of the landing entrance 9, the hook portion 24a or 25a is moved upward from the bottom of the scaffold member 22 to be hooked on the hook member 32. In addition, for example, the hook member 32 is provided at the side end of the scaffold member 22 in the width direction of the landing entrance 9, and when the hook member 32 and the receiving member 33 are separated in the depth direction of the landing entrance 9, the hook portion 24a or 25a is arranged from the side of the scaffold member 22 to the bottom of the hook member 32, and moved upward to be hooked on the hook member 32.

[0199] In the second embodiment, the hook 32 may be attached to a portion other than the scaffolding plate 22a of the scaffolding member 22. In this case, for example, the hook 32 is attached to the reinforcing plate 22b.

[0200] In the second embodiment, the socket 33 may be attached to a portion other than the wall 3 in the hoistway 1. In this case, for example, a support member is fixed to the hoistway 1, and the socket 33 is attached to the support member.

[0201] In Embodiment 2, the receiving member 33 may not have the hook portion 33a. In this case, for example, the receiving member 33 may have a hole opened upward, and the hook portion 32a of the hook member 32 may be placed in the hole from above in the stored state, thereby hooking the hook member 32.

[0202] In the second embodiment, the hook member 32 may be provided on the hoistway 1 , and the receiving member 33 may be provided on the scaffold member 22 .

[0203] In the second embodiment, the through-hole 22d, the hook 32, and the receiving piece 33 on one side of the width direction of the landing entrance 9 or the through-hole 22d, the hook 32, and the receiving piece 33 on the other side of the width direction of the landing entrance 9 may not be provided.

[0204] In the second embodiment, the hooking member 32 may be provided at the middle portion of the scaffold member 22 in the width direction of the landing entrance 9 , and the receiving member 33 may be provided at the middle portion of the wall 3 in the width direction of the landing entrance 9 .

[0205] In Embodiment 2, three or more sets of through-portions 22d, hooks 32, and receiving members 33 may be provided. In this case, the number of hooks 32 and receiving members 33 is determined based on the holding force for holding the hooks 32 hooked on the receiving members 33, for example.

[0206] Next, use Figure 21 to Figure 24 The scaffold device 41 of the elevator according to the third embodiment will be described.
