DETAILED DESCRIPTION OF THE INVENTION

[0007] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0008] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0009] An embodiment of an elevator hall device unit will be described below with reference to Figures 1 to 17. Note that the following embodiment is provided as an example to facilitate understanding of the configuration of the elevator hall device unit, and is not intended to limit the configuration of the elevator hall device unit.

[0010] First, before describing the components of the elevator hall device unit (hereinafter also simply referred to as "hall device unit"), the elevator will be described.

[0011] As shown in Fig. 1, an elevator 1 may include, for example, a car 2 for people (passengers) to ride in, a car drive unit 3 for running the car 2, a car rail 1a for guiding the car 2, and a processing unit 1b for controlling each part of the elevator 1. The drive system of the car drive unit 3 is not particularly limited.

[0012] For example, as in this embodiment, the elevator 1 may be configured to include a car rope 1c having a first end connected to the car 2, a counterweight 1d connected to a second end of the car rope 1c, and a counterweight rail 1e that guides the counterweight 1d, and the car drive unit 3 may be configured to include a sheave 3a around which the car rope 1c is wound, a drive source 3b (e.g., a motor) that rotates the sheave 3a, and a braking unit 3c (e.g., a brake) that brakes the sheave 3a.

[0013] That is, the car drive unit 3 may be a hoist and the elevator 1 may be a rope-type drive system. However, the present invention is not limited to such a configuration, and may be configured, for example, such that the car drive unit 3 is a hydraulic device and the elevator 1 is a hydraulic drive system, or such that the car drive unit 3 is a linear motor and the elevator 1 is a linear motor-type drive system.

[0014] Furthermore, in this embodiment, the first end of the car rope 1c is connected to the car 2, and the second end of the car rope 1c is connected to the counterweight 1d, but the present invention is not limited to this configuration. For example, a configuration is also possible in which both ends of the car rope 1c are fixed to the upper or lower part of the hoistway W1, and the car rope 1c is wound around the sheaves of the car 2 and the counterweight 1d, respectively, thereby connecting the car rope 1c to the car 2 and the counterweight 1d, respectively.

[0015] Furthermore, the elevator 1 according to this embodiment is configured such that the hoisting machine, which is the car drive unit 3, is located inside the machine room W2, but is not limited to such a configuration. For example, the elevator 1 may be configured such that the machine room W2 is not provided and the hoisting machine is located inside the hoistway W1.

[0016] The first lateral direction X1 is also referred to as the first horizontal direction X1, the second lateral direction Y1 is also referred to as the second horizontal direction Y1 which is a horizontal direction perpendicular to the first horizontal direction X1, and the up-down direction Z1 is also referred to as the vertical direction Z1 which is perpendicular to each of the horizontal directions X1 and Y1, and is the ascending and descending direction in which the car 2 and the counterweight 1d ascend and descend. Furthermore, although not particularly limited, the entrance and exit direction in which people move to enter and exit the car 2 may be, for example, the second horizontal direction Y1 as in this embodiment.

[0017] The elevator 1 includes a landing device 10 attached to the opening W3a of the landing W3. For example, as in the present embodiment, the landing device 10 may include landing doors 11 and 12 that move between an open position that opens the opening W3a of the landing W3 and a closed position that closes it, and a jamb 13 fixed to the opening W3a of the landing W3.

[0018] As in the present embodiment, the car 2 may include, for example, a car chamber 2a for passengers to ride in, a car door 2b that moves between an open position that opens the opening 2c of the car chamber 2a and a closed position that closes the opening 2c in order to open and close the opening 2c of the car chamber 2a, and a door drive unit 2d that performs the opening and closing operation of the car door 2b. Then, for example, a configuration may be possible in which the car door 2b opens and closes the opening 2c of the car chamber 2a using the door drive unit 2d, so that the hall doors 11 and 12 of the hall W3 at which the car 2 is stopped open and close the opening W3a of the hall W3 in conjunction with the car door 2b.

[0019] The number of doors 2b, 11, 12 is not particularly limited, and may be, for example, two as in this embodiment, or may be, for example, one or three or more. Furthermore, the opening and closing method of the doors 2b, 11, 12 is not particularly limited, and the doors 2b, 11, 12 may be configured to move in the same direction when opened and closed (one-side open type), for example, as in this embodiment, or may be configured to move in opposite directions when opened and closed (center open type). Furthermore, the moving direction of the doors 2b, 11, 12 may be, for example, the first horizontal direction X1 as in this embodiment.

[0020] 2 and 3, the landing device 10 includes a threshold portion 14 extending in a first direction D1, and a header portion 15 extending in the first direction D1 and moving away from the threshold portion 14 in a second direction D2 perpendicular to the first direction D1. The landing device 10 also includes a threshold bracket 16 that protrudes outward from the threshold portion 14 in the second direction D2 and is fixed to the threshold portion 14 and the skeleton W3b of the landing W3, and a header bracket 17 that protrudes outward from the header portion 15 in the second direction D2 and is fixed to the header portion 15 and the skeleton W3b of the landing W3, respectively.

[0021] The first direction D1, the second direction D2, and the third direction D3 perpendicular to the first direction D1 and the second direction D2 are used as the directions D1 to D3 in the hall device 10 and the directions D1 to D3 in a hall device unit described later. For example, as in this embodiment, in a state in which the hall device 10 is attached to the opening W3a of the hall W3, the first direction D1 may be parallel to the first horizontal direction X1, the second direction D2 may be parallel to the vertical direction Z1, and the third direction D3 may be parallel to the second horizontal direction Y1.

[0022] The header portion 15 may include, for example, as in this embodiment, a plate-shaped header body 15a extending in the first direction D1 and a guide rail 15b extending in the first direction D1 and fixed to the header body 15a. The header body 15a may be fixed to the frame W3b by a header bracket 17, for example, as in this embodiment.

[0023] The landing doors 11, 12 may include, for example, door bodies 11a, 12a that open and close the opening W3a of the landing W3, and guide rollers 11b, 12b that are connected to the door bodies 11a, 12a and are guided by the guide rail 15b, as in the present embodiment. Note that in the present embodiment, since the landing doors 11, 12 are of a one-side open type, for example, when the landing doors 11, 12 are located in the closed position, the first landing door 11 may be configured to abut against the jamb 13 in the first direction D1.

[0024] Furthermore, the threshold portion 14 may be provided with, for example, a guide groove (not shown) extending in the first direction D1 in order to guide the lower ends of the landing doors 11, 12. The threshold portion 14 may be fixed to the frame W3b by, for example, a threshold bracket 16 as in this embodiment.

[0025] The threshold bracket 16 may, for example, as in this embodiment, have a base portion 16a fixed to the threshold portion 14 and a protrusion portion 16b protruding downward from the base portion 16a. Note that the part having the protrusion portion 16b may, for example, as in this embodiment, be separate from the part having the base portion 16a, or may, for example, be the same body (integral body) as the part having the base portion 16a.

[0026] Furthermore, the header bracket 17 may include, for example, a base portion 17a fixed to the header portion 15, and a protrusion 17b protruding upward from the base portion 17a, as in this embodiment. Note that the component having the protrusion 17b may be the same (integrated) component as the component having the base portion 17a, as in this embodiment, or may be separate from the component having the base portion 17a.

[0027] The landing device 10 may, for example, as in the present embodiment, include a first fixing means 18 that fixes the base portion 16a of the threshold bracket 16 to the threshold portion 14, and a second fixing means 19 that fixes the base portion 17a of the header bracket 17 to the header portion 15. Although not particularly limited, the first and second fixing means 18, 19 may, for example, as in the present embodiment, be fasteners (for example, bolts and nuts), or may be, for example, welding.

[0028] The protrusion 16b of the threshold bracket 16 may be fixed to the body W3b by, for example, a third fixing means 4. Although not particularly limited, the third fixing means 4 may be, for example, as in this embodiment, a fastener (for example, a nut and a male-threaded anchor bolt embedded in the body W3b, or a bolt and a female-threaded anchor bolt embedded in the body W3b), or may be, for example, welding.

[0029] The protrusion 17b of the header bracket 17 may be fixed to the body W3b by, for example, a fourth fixing means 5. Although not particularly limited, the fourth fixing means 5 may be, for example, as in this embodiment, a fastener (for example, a nut and a male-threaded anchor bolt embedded in the body W3b, or a bolt and a female-threaded anchor bolt embedded in the body W3b), or may be, for example, welding.

[0030] <First conveying process> Next, the first transport step in the manufacturing method of the hall device 10 will be described with reference to FIGS.

[0031] In the first transport step, the hall device 10 is transported as a hall device unit 7. Although not particularly limited, the first transport step may be, for example, a step in which the hall device unit 7 is transported within a building in which the hall device 10 is manufactured (a transport step within a manufacturing building), or may be, for example, a step in which the hall device unit 7 is transported from a building in which the hall device 10 is manufactured to a building in which the hall device 10 is to be installed (a transport step between buildings).

[0032] As shown in Figures 4 and 5, the hall device unit 7 includes a hall device 10 and a jig 20 that is removably attached to the hall device 10. The length of the hall device unit 7 in the first direction D1 is shorter than the length of the hall device unit 7 in the second direction D2. In Figures 4 and 5 (as well as Figure 9), the hall device 10 is shown by a two-dot chain line (note that an enlarged view of the dashed dot line in Figure 5 is shown by a solid line), and the jig 20 is shown by a solid line.

[0033] The landing device 10 constituting the landing device unit 7 includes at least one of the landing doors 11, 12, the jamb 13, the threshold portion 14, the header portion 15, the threshold bracket 16, and the header bracket 17. Although not particularly limited, for example, as in the present embodiment, the landing device 10 constituting the landing device unit 7 may include all of the components 11 to 17.

[0034] The jig 20 includes a first outer frame portion 21 and a second outer frame portion 22 that extend in the second direction D2 and connect the threshold portion 14 and the header portion 15, and a first connection portion 23, a second connection portion 24, and a third connection portion 25 that connect the first outer frame portion 21 and the second outer frame portion 22. Note that, although not particularly limited thereto, at least one of the outer frame portions 21, 22 and the connection portions 23, 24, 25 may be configured to be extendable and contractible, for example.

[0035] Furthermore, the jig 20 may include, for example, as in this embodiment, temporary fixing means (e.g., bands) 26 that temporarily fix the landing doors 11, 12 to the jamb 13, fifth fixing means 27 that detachably fix the outer frame portions 21, 22 and the threshold portion 14, sixth fixing means 28 that detachably fix the outer frame portions 21, 22 and the header portion 15, and seventh fixing means 29 that detachably fix the connection portions 23, 24, 25 to the outer frame portions 21, 22.

[0036] The first outer frame portion 21 and the second outer frame portion 22 are removably attached to the threshold portion 14 and the header portion 15 by fixing means 27, 28. Although not particularly limited, the fifth and sixth fixing means 27, 28 may be, for example, fasteners (e.g., bolts and nuts) as in this embodiment.

[0037] The outer frame portions 21, 22 may have, for example, as in the present embodiment, a plurality of suspension holes 21a-21d for suspension (the suspension holes of the second outer frame portion 22 are not shown). The plurality of suspension holes 21a-21d may have, for example, as in the present embodiment, a first end hole 21a arranged at first ends 21e, 22e in the second direction D2 of the outer frame portions 21, 22, a second end hole 21b arranged at second ends 21f, 22f in the second direction D2 of the outer frame portions 21, 22, and a first inner hole 21c and a second inner hole 21d arranged between the first end hole 21a and the second end hole 21b.

[0038] As a result, for example, by attaching the end of the wire V1 to the first end hole 21a of each of the first outer frame portion 21 and the second outer frame portion 22, the hall device unit 7 is suspended in a vertical position in which the second direction D2 is along the vertical direction Z1, as shown in Fig. 6(a). Also, for example, by attaching the end of the wire V1 to the first and second middle holes 21c, 21d (see Fig. 5) of the first outer frame portion 21, the hall device unit 7 is suspended in a horizontal position in which the first direction D1 is along the vertical direction Z1, as shown in Fig. 6(b).

[0039] 4 and 5, the first outer frame portion 21 is disposed outside (to the right in FIG. 4) the first ends (right ends in FIG. 4) of the threshold portion 14 and the header portion 15 in the first direction D1. The second outer frame portion 22 is disposed outside (to the left in FIG. 4) the second ends (left ends in FIG. 4) of the threshold portion 14 and the header portion 15 in the first direction D1.

[0040] As a result, for example, when the landing device unit 7 is being transported, an external object will hit the outer frame portions 21, 22 from the first direction D1. Therefore, it is possible to prevent the ends of the threshold portion 14 and the header portion 15 in the first direction D1 from being hit from the first direction D1. As a result, it is possible to prevent damage to the threshold portion 14 and the header portion 15, for example.

[0041] Furthermore, the second ends 21f, 22f of the outer frame portions 21, 22 are disposed further outward in the second direction D2 (lower in FIGS. 4 and 5) than the threshold portion 14. Furthermore, the second ends 21f, 22f of the outer frame portions 21, 22 (specifically, the ends of the outer frame portions 21, 22 in the second direction D2) are disposed further outward in the second direction D2 than the threshold bracket 16 (lower in FIGS. 4 and 5).

[0042] As a result, for example, when the landing device unit 7 is being transported, an external object will hit the second ends 21f, 22f of each outer frame portion 21, 22 from the second direction D2. Therefore, it is possible to prevent the threshold portion 14 and the threshold bracket 16 from being hit from the second direction D2. As a result, it is possible to prevent damage to the threshold portion 14 and the threshold bracket 16, for example.

[0043] Furthermore, the first ends 21e, 22e of the outer frame portions 21, 22 may be disposed, for example, as in this embodiment, further outward in the second direction D2 (upper side in FIGS. 4 and 5) than the header portion 15. Furthermore, the first ends 21e, 22e of the outer frame portions 21, 22 (specifically, the ends of the outer frame portions 21, 22 in the second direction D2) may be disposed, for example, as in this embodiment, further outward in the second direction D2 than the header bracket 17 (upper side in FIGS. 4 and 5).

[0044] As a result, for example, when the landing device unit 7 is being transported, an external object will hit the first ends 21e, 22e of the outer frame portions 21, 22 from the second direction D2. This prevents the header portion 15 and the header bracket 17 from being hit from the second direction D2. As a result, for example, damage to the header portion 15 and the header bracket 17 can be prevented.

[0045] Note that, for example, as in this embodiment, the header bracket 17 may be detachable from the header portion 15 by the second fixing means 19 so that the attitude relative to the header portion 15 can be changed. As a result, the header bracket 17 is fixed to the header portion 15 in a temporary attitude (see FIGS. 4 and 5) when being transported as the landing device unit 7, and is fixed to the header portion 15 in a main attitude (see FIGS. 2 and 3) when being fixed to the body W3b.

[0046] 2 and 3, when the header bracket 17 is in the normal position, the protrusion 17b of the header bracket 17 protrudes outward in the second direction D2 (upward in FIGS. 2 and 3) from the base 17a of the header bracket 17. On the other hand, when the header bracket 17 is in the temporary position, as shown in FIGS. 4 and 5, the protrusion 17b of the header bracket 17 protrudes inward in the second direction D2 (downward in FIGS. 4 and 5) from the base 17a of the header bracket 17.

[0047] As a result, the first ends 21e, 22e of the outer frame portions 21, 22 (specifically, the ends of the outer frame portions 21, 22 in the second direction D2) are disposed further outward in the second direction D2 (upper side in FIGS. 4 and 5) than the header bracket 17. Note that this configuration is not limited to this, and for example, the header bracket 17 may be fixed to the header portion 15 in the same posture (original posture) both when being transported as the hall device unit 7 and when fixed to the body W3b.

[0048] First ends 23a, 24a, 25a of the connection portions 23, 24, 25 are attached to the first outer frame portion 21, and second ends 23b, 24b, 25b of the connection portions 23, 24, 25 are attached to the second outer frame portion 22. In this way, the connection portions 23, 24, 25 connect the first outer frame portion 21 and the second outer frame portion 22.

[0049] Therefore, when the first outer frame portion 21 and the second outer frame portion 22 are hit from the first direction D1, the first outer frame portion 21 and the second outer frame portion 22 can be reinforced by the connecting portions 23, 24, 25. Furthermore, for example, even when the first outer frame portion 21 and the second outer frame portion 22 are pulled outward in the first direction D1, the first outer frame portion 21 and the second outer frame portion 22 can be reinforced by the connecting portions 23, 24, 25.

[0050] When viewed in the third direction D3, the first ends 23a, 24a, 25a of the connecting portions 23, 24, 25 are spaced apart from each other, while the second ends 23b, 24b, 25b of the connecting portions 23, 24, 25 overlap each other. As a result, when viewed in the third direction D3, the two connecting portions 23, 24 (23, 25; 24, 25) and a part of the first outer frame portion 21 form a triangle.

[0051] Therefore, for example, when viewed in the third direction D3, the strength of the triangular portion formed by the two connecting portions 23, 24 (23, 25; 24, 25) and part of the first outer frame portion 21 can be increased compared to when the two connecting portions 23, 24 (23, 25; 24, 25), part of the first outer frame portion 21 and part of the second outer frame portion 22 form a rectangle.

[0052] Moreover, when viewed in the third direction D3, the first connecting portion 23 intersects the first outer frame portion 21 and the second outer frame portion 22 perpendicularly. This allows the first connecting portion 23 to increase the strength in the first direction D1 when the first outer frame portion 21 and the second outer frame portion 22 are hit from the first direction D1. Therefore, for example, when an external force in the first direction D1 is applied to the outer frame portions 21, 22, it is possible to prevent the triangular portion formed by the two connecting portions 23, 24 (23, 25; 24, 25) and a part of the first outer frame portion 21 from deforming.

[0053] 7 and 8, end portions 23a, 23b, 24a, 24b, 25a, and 25b of the connecting portions 23, 24, and 25 are provided with connecting holes 23c, 24c, and 25c. Note that only second end portions 23b, 24b, and 25b of the connecting portions 23, 24, and 25 are shown in FIGS.

[0054] The seventh fixing means 29 includes protruding portions 29a that protrude from the outer frame portions 21 and 22 in the third direction D3 and are inserted into the connection holes 23c, 24c, and 25c, and retaining portions 29b that prevent the protruding portions 29a from coming out of the connection holes 23c, 24c, and 25c. Note that only the second outer frame portion 22 is shown in Figures 7 and 8.

[0055] Since the retaining portions 29b are removably attached to the protruding portions 29a, the retaining portions 29b prevent the protruding portions 29a from coming out of the connection holes 23c, 24c, and 25c. As a result, the ends 23a, 23b, 24a, 24b, 25a, and 25b of the respective connecting portions 23, 24, and 25 are sandwiched between the retaining portions 29b and the outer frames 21 and 22, and the ends 23a, 23b, 24a, 24b, 25a, and 25b of the respective connecting portions 23, 24, and 25 are attached to the outer frames 21 and 22.

[0056] Therefore, connection holes 23c, 24c, 25c of second ends 23b, 24b, 25b of connection portions 23, 24, 25 are inserted into the same protrusion 29a, and retaining portion 29b is attached to protrusion 29a, thereby attaching second ends 23b, 24b, 25b of connection portions 23, 24, 25 to second outer frame portion 22. In this way, multiple connection portions 23, 24, 25 can be attached to second outer frame portion 22 by attaching one retaining portion 29b to one protrusion 29a.

[0057] Furthermore, when retaining portion 29b is removed from protrusion 29a and connection holes 23c, 24c, 25c of second ends 23b, 24b, 25b of connection portions 23, 24, 25 are removed from the same single protrusion 29a, second ends 23b, 24b, 25b of connection portions 23, 24, 25 are removed from second outer frame portion 22. Thus, multiple connection portions 23, 24, 25 can be removed from second outer frame portion 22 by removing one retaining portion 29b from one protrusion 29a.

[0058] In this way, by attaching or detaching one retaining portion 29b to or from one protrusion 29a, it is possible to attach or detach multiple connection portions 23, 24, 25 to or from second outer frame portion 22. Therefore, for example, it is possible to easily attach or detach multiple connection portions 23, 24, 25 to or from second outer frame portion 22.

[0059] <Second conveying process> Next, the second transport step in the manufacturing method of the hall device 10 will be described with reference to FIGS.

[0060] Although not particularly limited, the second transport step may be, for example, a step of transporting the hall device unit 7 from a hall on a reference floor (hereinafter also referred to as a "reference hall") W4 (see FIGS. 11 to 14) to an opening W5a of a hall (hereinafter also referred to as an "mounting hall") W5 (see FIG. 14) that is above the reference hall W4 and to which the hall device 10 is mounted (also referred to as an "mounting hall"). Note that, although not particularly limited, the reference hall W4 may be, for example, a hall (generally a hall on the first floor) where the hall device unit 7 is temporarily placed when it is transported into the building.

[0061] 9 and 10, the jig 20 of the landing device unit 7 in the second transport step includes a connecting portion 31a to which the mounting portion V2a (see FIGS. 11 to 14) of the lifting device V2 can be attached. For example, as in this embodiment, the jig 20 includes the connecting device 30 that connects the first outer frame portion 21 and the second outer frame portion 22, and the connecting portion 31a may be provided on the connecting device 30.

[0062] For example, as in this embodiment, the connector 30 may include a plate-shaped connector body 31 having a connecting portion 31a, an outer tube portion 32 fixed to the connector body 31, an inner tube portion 33 inserted into the outer tube portion 32, and an eighth fixing means 34 that fixes the outer tube portion 32 and the inner tube portion 33. By changing the fixed position of the inner tube portion 33 relative to the outer tube portion 32, the length of the connector 30 in the first direction D1 can be changed.

[0063] Although not particularly limited, for example, the eighth fixing means 34 may include a bolt 34a and a plurality of nuts 34b fixed inside the inner cylindrical portion 33, and the connecting body 31, the outer cylindrical portion 32, and the inner cylindrical portion 33 may include bolt holes 31b, 32a, and 33a into which the bolt 34a is inserted. As a result, the length of the connecting device 30 in the first direction D1 can be changed by changing the bolt holes 31b, 32a, and 33a into which the bolt 34a is inserted and the nuts 34b into which the bolt 34a is screwed.

[0064] Furthermore, the jig 20 can be attached to a plurality of types of hall devices 10 that have different lengths in the first direction D1 and / or the second direction D2, for example. A plurality of connecting portions 31a are provided so as to be aligned in the first direction D1 in accordance with the center of gravity positions in the first direction D1 of the hall device units 7 corresponding to the plurality of types of hall devices 10, and the connecting device 30 is provided with an indicator 31c that indicates the center of gravity position of the hall device unit 7.

[0065] Although not particularly limited, for example, as shown in Fig. 10, the display unit 31c may display the type of the landing device 10 (type "A", "B", or "C") and the side of the closed position of the landing doors 11, 12 (the "L" (left) side, the "R" (right) side). For example, if the type of the landing device 10 is type "A" and the side of the closed position of the landing doors 11, 12 is the "L" side, the position of the center of gravity of the landing device unit 7 in the first direction D1 is the position of the fourth connecting portion 31a from the left among the nine connecting portions 31a in Fig. 10.

[0066] This makes it possible to easily grasp the position of the center of gravity of the landing device unit 7 in the first direction D1 using the display unit 31c. In particular, in the case where the landing doors 11, 12 are of a one-side open type as in the present embodiment, the position of the center of gravity of the landing device unit 7 in the first direction D1 is away from the center of the landing device unit 7 in the first direction D1, but the position of the center of gravity of the landing device unit 7 in the first direction D1 can be easily grasped using the display unit 31c.

[0067] Furthermore, the connecting portion 31a may be configured to be rotatably attached to the attachment portion V2a, as in the present embodiment. Although not particularly limited, the connecting portion 31a may be, for example, a circular through-hole, as in the present embodiment.

[0068] In the second transport step, a lifting device V2 is used as shown in Figures 11 to 14. In the enlarged view of the dashed-dotted line area in Figure 14, only the connecting body 31 is shown in cross section.

[0069] The lifting device V2 includes an attachment part V2a that is detachably attached to the connecting part 31a (see FIGS. 12 and 14) of the landing device unit 7, a string-like body V2b that is connected to the attachment part V2a, and a device main body V2c that is disposed inside the elevator shaft W1 and pulls up the string-like body V2b. Note that the device main body V2c may be attached to a frame above the opening of the landing on the top floor by a support device, for example, as in this embodiment.

[0070] In this embodiment, the attachment portion V2a is a hook and the string-like body V2b is a rope (i.e., composed of one member), but the configuration is not limited to this. For example, the lifting device V2 may further include a wire connecting the connecting portion 31a and the hook, the attachment portion V2a being the end of the wire, and the string-like body V2b being composed of the part of the wire other than the end, the hook, and the rope (i.e., composed of multiple members).

[0071] In the second transport process, first, as shown in FIG. 11, with the mounting portion V2a attached to only one connecting portion 31a of the landing device unit 7 and with the landing device unit 7 in a horizontal position, a part of the landing device unit 7 (the left part in FIG. 11) is placed inside the elevator shaft W1 through the opening W4a of the reference landing W4 (placement process).

[0072] The order of the step of attaching the mounting portion V2a to only one connecting portion 31a of the hall device unit 7 (connecting step) and the step of inserting a part of the hall device unit 7 into the interior of the hoistway W1 from the opening W4a of the reference hall W4 (entering step) is not particularly limited. For example, the connecting step may come first and the entrance step may come later, or the entrance step may come first and the connecting step may come later. Furthermore, in the connecting step, the positions of the mounting portion V2a and the connecting portion 31a may be, for example, outside the hoistway W1, or may be, for example, inside the hoistway W1.

[0073] Then, in the placement step, a part of the hall device unit 7 (the left part in FIG. 11) is positioned inside the hallway W1 so that the mounting portion V2a is positioned inside the hallway W1. This allows the other part of the hall device unit 7 (the right part in FIG. 11) to be supported by the reference hall W4. Although not particularly limited, for example, the other part of the hall device unit 7 (the right part in FIG. 11) may be supported by a carriage (not shown) of the reference hall W4.

[0074] 12, the hall device unit 7 is turned in a state in which the attachment part V2a is attached to the connection part 31a of the hall device unit 7 so that the hall device unit 7 changes from a horizontal orientation to a vertical orientation (turning process). Then, in the turning process, the hall device unit 7 is turned while the device main body V2c pulls up the string-like body V2b.

[0075] As a result, the lifting device V2 can rotate the hall device unit 7 while supporting the hall device unit 7. Then, with the mounting part V2a attached to the connecting part 31a of the hall device unit 7, the hall device unit 7 is further rotated, and as shown in FIG. 13, the hall device unit 7 changes from the horizontal position to the vertical position.

[0076] Note that the position of the connecting part 31a may be away from the center of gravity in the second direction D2 of the hall device unit 7, for example, as in this embodiment. As a result, when the hall device unit 7 is hung in a state in which the mounting part V2a is attached to only one connecting part 31a, which is the center of gravity in the first direction D1 of the hall device unit 7, the hall device unit 7 will be in a vertical position due to gravity balance, as shown in FIG.

[0077] Thereafter, the string-like body V2b is pulled up, and the hall device unit 7 is raised in a vertical position to the position of the opening W5a of the attachment hall W5 (raising process). In the raising process, the hall device unit 7 is in a vertical position due to gravity balance, so that it is easy to, for example, put the hall device unit 7 in a vertical position.

[0078] Furthermore, because the outer frame parts 21, 22 are disposed outward from the end of the hall device 10 in the first direction D1 (see FIG. 9), for example, even if the hall device unit 7 swings in the first direction D1 inside the elevator shaft W1, the outer frame parts 21, 22 are hit from the first direction D1. This makes it possible to prevent the hall device 10 from being hit from the first direction D1, and therefore to prevent the hall device 10 from being deformed or damaged.

[0079] Furthermore, while the weight of the hall device unit 7 is heavy, the mounting portion V2a is attached to the connecting portion 31a of the jig 20, and therefore the force due to the weight of the hall device unit 7 is applied to the connecting portion 31a of the jig 20. As a result, the force due to the weight of the hall device unit 7 is not applied to the hall device 10, and therefore, for example, it is possible to prevent the hall device 10 from being deformed or damaged by the force.

[0080] In this way, with the mounting portion V2a attached to the connecting portion 31a at the same position on the landing device unit 7, the landing device unit 7 can be moved using the lifting device V2 from the opening W4a of the reference landing W4 to the position of the opening W5a of the attachment landing W5. This makes it possible to easily transport the landing device unit 7, for example, from the opening W4a of the reference landing W4 to the position of the opening W5a of the attachment landing W5.

[0081] <Installation process> Next, the installation step in the manufacturing method of the hall device 10 will be described with reference to FIGS.

[0082] When explaining the installation process, the landing device 10 attached to the opening W6a of the upper landing (hereinafter also referred to as the "upper landing") W6 is also referred to as the upper landing device 10a, and the landing device 10 attached to the opening W7a of the landing (hereinafter also referred to as the "lower landing") W7 directly below the upper landing W6 is also referred to as the lower landing device 10b.

[0083] Furthermore, the landing device unit 7 having the upper landing device 10a is also referred to as the upper landing device unit 7a, and the jig 20 of the upper landing device unit 7a is also referred to as the upper jig 20a. Furthermore, the landing device unit 7 having the lower landing device 10b is also referred to as the lower landing device unit 7b, and the jig 20 of the lower landing device unit 7b is also referred to as the lower jig 20b.

[0084] First, as shown in Fig. 15, with the upper jig 20a attached to the upper landing device 10a, the upper landing device 10a is fixed to the frame W6b of the upper landing W6 (upper fixing process). Note that, for example, as in this embodiment, the brackets 16, 17 of the upper landing device 10a may be fixed to the frame W6b of the upper landing W6 by the fixing means 4, 5, so that the threshold portion 14 and the header portion 15 are fixed to the frame W6b of the upper landing W6.

[0085] As a result, with the outer frame portions 21, 22 attached to the upper landing device 10a, the threshold portion 14 and the header portion 15 are fixed to the frame W6b of the upper landing W6. Therefore, the threshold portion 14 and the header portion 15 can be fixed to the frame W6b of the upper landing W6 while maintaining the positional relationship between the threshold portion 14 and the header portion 15.

[0086] The method for fixing the upper landing device 10a to the frame W6b of the upper landing W6 may be the same as or different from the method for fixing the lower landing device 10b to the frame W7b of the lower landing W7, which will be described later. Furthermore, although not particularly limited, the lower landing device unit 7b may be temporarily fixed to the frame W7b of the lower landing W7 when the upper fixing step is performed.

[0087] 16, the upper landing device unit 7a and the lower landing device unit 7b are connected by the first suspending tool V3 and the second suspending tool V4, and the lower landing device unit 7b is suspended from the upper landing device unit 7a (suspending process). For example, as in this embodiment, the upper ends of the suspending tools V3 and V4 may be attached to the second end holes 21b of the outer frame parts 21 and 22 of the upper jig 20a, and the lower ends of the suspending tools V3 and V4 may be attached to the first end holes 21a of the outer frame parts 21 and 22 of the lower jig 20b.

[0088] As a result, although the weight of the lower landing device unit 7b is heavy, the force due to the weight of the lower landing device unit 7b is applied to the upper jig 20a and the lower jig 20b because the hoisting devices V3 and V4 connect the upper jig 20a and the lower jig 20b. Therefore, for example, the force due to the weight of the lower landing device unit 7b is not applied to the upper landing device 10a and the lower landing device 10b, so deformation or damage to the upper landing device 10a and the lower landing device 10b can be suppressed.

[0089] Additionally, the outer frame portions 21 and 22 of the lower jig 20b are disposed outward from the end portion of the lower landing device 10b in the first horizontal direction X1. As a result, the center of gravity of the lower landing device unit 7b in the first horizontal direction X1 is located between the first outer frame portion 21 and the second outer frame portion 22 connected to the hoisting devices V3 and V4.

[0090] Moreover, the first suspender V3 connects the first outer frame portions 21, 21 of the jigs 20a, 20b, and the second suspender V4 connects the second outer frame portions 22, 22 of the jigs 20a, 20b. This allows the first suspender V3 and the second suspender V4 to be spaced far apart, allowing the lower landing device unit 7b to be stably suspended from the upper landing device unit 7a.

[0091] The upper ends of the suspenders V3 and V4 are attached to the second end holes 21b at the lower end of the upper jig 20a, and the lower ends of the suspenders V3 and V4 are attached to the first end holes 21a at the upper end of the lower jig 20b. This allows the length of the suspenders V3 and V4 to be shortened.

[0092] Moreover, the second end hole 21b, which is the lower end of the upper jig 20a, is positioned lower than the threshold bracket 16, which is the lower end of the upper landing device 10a. This allows the length of the hoisting devices V3 and V4 to be further shortened, so that the lower landing device unit 7b can be stably suspended from the upper landing device unit 7a. Therefore, for example, when the lower landing device unit 7b is suspended from the upper landing device unit 7a by the hoisting devices V3 and V4, it is possible to prevent the lower landing device unit 7b from swaying.

[0093] The suspenders V3 and V4 also include length-adjusting portions V3a and V4a. Although not particularly limited, the suspenders V3 and V4 may include, for example, as in the present embodiment, an attachment portion V3b that is detachably attached to the lower jig 20b, a string-like body V3c that is connected to the attachment portion V3b, and a tool main body V3d that is detachably attached to the upper jig 20a and that pulls up the string-like body V3c.

[0094] As a result, the modified portion V3a is composed of the string-like body V3c and the tool body V3d. Note that the hoisting tools V3 and V4 may be, for example, chain blocks (hoists) as in this embodiment, or may also be, for example, turnbuckles.

[0095] Then, by changing the lengths of the suspenders V3 and V4, the position of the lower landing device 10b is aligned with the opening W7a of the lower landing W7 (alignment process). As a result, for example, in the case where the landing doors 11 and 12 are of the one-side open type as in the present embodiment, even if the center of gravity position in the first direction D1 of the lower landing device unit 7b is away from the center of the first direction D1, the position of the lower landing device 10b can be easily aligned with the opening W7a of the lower landing W7.

[0096] 17, with the lower jig 20b attached to the lower landing device 10b, the lower landing device 10b is fixed to the frame W7b of the lower landing W7 (lower fixing process). As a result, with the outer frame portions 21 and 22 attached to the lower landing device 10b, the threshold portion 14 and the header portion 15 are fixed to the frame W7b of the lower landing W7.

[0097] Therefore, the threshold portion 14 and the header portion 15 can be fixed to the frame W7b of the descending landing W7 while maintaining the positional relationship between the threshold portion 14 and the header portion 15. Note that, for example, as in the present embodiment, the brackets 16, 17 of the descending landing device 10b may be fixed to the frame W7b of the descending landing W7 by the fixing means 4, 5, thereby fixing the threshold portion 14 and the header portion 15 to the frame W7b of the descending landing W7.

[0098] This allows the lower landing device 10b to be fixed to the frame W7b of the lower landing W7 directly below using the upper landing device unit 7a having the upper landing device 10a fixed to the frame W6b of the upper upper landing W6 directly above. Therefore, for example, the lower landing device 10b can be easily fixed to the frame W7b.

[0099] Thereafter, the upper jig 20a is removed from the upper landing device 10a (upper removal step). This allows only the upper landing device 10a to be attached to the opening W6a of the upper landing W6.

[0100] [1] As described above, the manufacturing method of the elevator hall device 10 is as follows, as in this embodiment: A manufacturing method of an elevator hall device 10 using an upper hall device unit 7a having an upper hall device 10a attached to an opening W6a of a first hall (an upper hall in this embodiment) W6, and a lower hall device unit 7b having a lower hall device 10b attached to an opening W7a of a second hall (a lower hall in this embodiment) W7 directly below the first hall W6, an upper fixing step of fixing the upper landing device 10a to the body W6b; After the upper fixing step, a suspending step is performed in which the upper landing device unit 7a and the lower landing device unit 7b are connected with suspenders V3 and V4 to suspend the lower landing device unit 7b from the upper landing device unit 7a. A lower fixing step of fixing the lower landing device 10b to the body W7b after the hanging step. This method is preferred.

[0101] According to this method, the upper landing device 10a is fixed to the frame W6b of the first landing (upper landing) W6. After that, the upper landing device unit 7a and the lower landing device unit 7b are connected by the hoisting devices V3 and V4, so that the lower landing device unit 7b is suspended from the upper landing device unit 7a.

[0102] Thereafter, the lower landing device 10b is fixed to the frame W7b of the second landing (lower landing) W7. This allows the landing device (lower landing device) 10b to be fixed to the frame W7b using the landing device unit (upper landing device unit) 7a having the landing device (upper landing device) 10a fixed to the frame W6b of the landing (upper landing) W6 directly above.

[0103] [2] In addition, in the manufacturing method of the elevator hall device 10 described above in [1], as in this embodiment, The upper landing device unit 7a includes an upper jig 20a that is removably attached to the upper landing device 10a, The lower landing device unit 7b includes a lower jig 20b that is removably attached to the lower landing device 10b, In the hanging process, the hanging tools V3 and V4 connect the upper jig 20a and the lower jig 20b. This method is preferred.

[0104] With this configuration, since the lower landing device unit 7b is heavy, the lifting devices V3 and V4 connect the upper jig 20a and the lower jig 20b, so that the force due to the weight of the lower landing device unit 7b is applied to the upper jig 20a and the lower jig 20b.

[0105] [3] In addition, in the manufacturing method of the elevator hall device 10 described above in [2], as in this embodiment, The upper ends of the suspenders V3 and V4 are attached to the lower end of the upper jig 20a. The lower ends of the suspenders V3 and V4 are attached to the upper end of the lower jig 20b. The lower end of the upper jig 20a is positioned lower than the lower end of the upper landing device 10a. This method is preferred.

[0106] According to this method, the upper ends of the suspenders V3 and V4 are attached to the lower end of the upper jig 20a, and the lower ends of the suspenders V3 and V4 are attached to the upper end of the lower jig 20b, thereby shortening the length of the suspenders V3 and V4.

[0107] Moreover, the lower end of the upper jig 20a is positioned lower than the lower end of the upper landing device 10a. This allows the length of the hoisting devices V3 and V4 to be further shortened. Therefore, the lower landing device unit 7b can be stably hoisted on the upper landing device unit 7a.

[0108] [4] In addition, in the manufacturing method of the elevator hall device 10 described above in [2] or [3], as in this embodiment, The upper jig 20a is A first outer frame portion 21 arranged outside a first end portion of the upper landing device 10a in the first horizontal direction X1; A second outer frame portion 22 is arranged outside the second end portion of the upper landing device 10a in the first horizontal direction X1, The lower jig 20b is A first outer frame portion 21 arranged outside a first end portion of the lower landing device 10b in the first horizontal direction X1; a second outer frame portion 22 arranged outside a second end portion of the lower landing device 10b in the first horizontal direction X1, The suspenders V3 and V4 are: a first suspender V3 that connects the first outer frame portion 21 of the upper jig 20a and the first outer frame portion 21 of the lower jig 20b; A second suspender V4 that connects the second outer frame portion 22 of the upper jig 20a and the second outer frame portion 22 of the lower jig 20b, This method is preferred.

[0109] According to this method, the outer frame portions 21, 22 of the lower jig 20b are positioned outward from the ends of the lower landing device 10b in the first horizontal direction X1. As a result, the center of gravity of the lower landing device unit 7b in the first horizontal direction X1 is located between the first outer frame portion 21 and the second outer frame portion 22 connected to the hoisting devices V3, V4.

[0110] Moreover, the first suspender V3 connects the first outer frame portions 21, 21 of the jigs 20a, 20b, and the second suspender V4 connects the second outer frame portions 22, 22 of the jigs 20a, 20b. This allows the first suspender V3 and the second suspender V4 to be spaced far apart, allowing the lower landing device unit 7b to be stably suspended from the upper landing device unit 7a.

[0111] [5] In addition, in the manufacturing method of the elevator hall device 10 according to any one of the above [2] to [4], as in this embodiment, The upper landing device 10a is a threshold portion 14 extending in a first horizontal direction X1; a header portion 15 extending in the first horizontal direction X1 and spaced apart from the threshold portion 14 in the vertical direction Z1; The upper jig 20a includes outer frame portions 21 and 22 that connect the threshold portion 14 and the header portion 15, The upper ends of the suspenders V3 and V4 are attached to the lower end of the upper jig 20a. The lower ends of the suspenders V3 and V4 are attached to the upper end of the lower jig 20b. The lower end of the upper jig 20a is disposed below the threshold portion 14. This method is preferred.

[0112] According to this method, the upper ends of the suspenders V3 and V4 are attached to the lower end of the upper jig 20a, and the lower ends of the suspenders V3 and V4 are attached to the upper end of the lower jig 20b, thereby shortening the length of the suspenders V3 and V4.

[0113] Moreover, the lower end of the upper jig 20a is positioned below the threshold 14. This allows the length of the hoisting devices V3 and V4 to be further shortened. Therefore, the lower landing device unit 7b can be stably suspended from the upper landing device unit 7a.

[0114] [6] In addition, in the manufacturing method of any one of the elevator hall apparatus 10 described above [1] to [5], as in this embodiment, The suspenders V3 and V4 have length-adjustable portions V3a and V4a, The manufacturing method further includes an alignment step of aligning the position of the lower landing device 10b with the opening W7a of the second landing (in this embodiment, the lower landing) W7 by changing the lengths of the hanging tools V3 and V4 after the hanging step and before the lower fixing step. This method is preferred.

[0115] According to this method, after the lower landing device unit 7b is suspended from the upper landing device unit 7a, the lengths of the suspenders V3 and V4 are changed, thereby allowing the position of the lower landing device 10b to be aligned with the opening W7a of the second landing (lower landing) W7. After the position of the lower landing device 10b is aligned, the lower landing device 10b is fixed to the frame W7b.

[0116] [7] In addition, the landing device unit 7, as in this embodiment, The method for manufacturing the elevator hall device 10 according to any one of the above [1] to [6], which is used for at least one of the upper hall device unit 7a and the lower hall device unit 7b, This configuration is preferable.

[0117] According to this configuration, the landing device (lower landing device unit) 7b can be fixed to the frame W7b using the landing device unit (upper landing device unit) 7a fixed to the frame W6b of the landing (upper landing) W6 directly above.

[0118] The manufacturing method of the elevator hall device 10 and the hall device unit 7 are not limited to the configurations of the above-described embodiments, and are not limited to the above-described effects. Furthermore, it goes without saying that various modifications can be made to the manufacturing method of the elevator hall device 10 and the hall device unit 7 without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations, methods, etc. according to the various modified examples described below may be arbitrarily selected and adopted in the configurations, methods, etc. according to the above-described embodiments.

[0119] (A) In the hall device unit 7 according to the above embodiment, the jig 20 is configured to include three connection portions 23, 24, 25 that connect the first outer frame portion 21 and the second outer frame portion 22. However, the hall device unit 7 is not limited to this configuration.

[0120] For example, the jig 20 may be configured to include one, two, four or more connecting portions 23, 24, 25 that connect the first outer frame portion 21 and the second outer frame portion 22. Alternatively, for example, the jig 20 may be configured to not include the connecting portions 23, 24, 25 that connect the first outer frame portion 21 and the second outer frame portion 22.

[0121] (B) Furthermore, in the hall device unit 7 according to the above embodiment, the second end 23b of the first connecting portion 23 overlaps with the second end 24b of the second connecting portion 24 when viewed in the third direction D3. However, the hall device unit 7 is not limited to this configuration.

[0122] For example, the second end 23b of the first connection portion 23 may be configured to be spaced apart from the second end 24b of the second connection portion 24 when viewed in the third direction D3. That is, when viewed in the third direction D3, the first connection portion 23, the second connection portion 24, a portion of the first outer frame portion 21, and a portion of the second outer frame portion 22 may form a quadrangle.

[0123] (C) Furthermore, in the hall device unit 7 according to the above embodiment, the first connection portion 23 intersects the first outer frame portion 21 and the second outer frame portion 22 perpendicularly when viewed in the third direction D3, and the second connection portion 24 and the third connection portion 25 intersect at an angle relative to the first outer frame portion 21 and the second outer frame portion 22 when viewed in the third direction D3. However, the hall device unit 7 is not limited to such a configuration.

[0124] For example, all of the connection portions 23, 24, 25 may be configured to intersect orthogonally with the first outer frame portion 21 and the second outer frame portion 22 when viewed in the third direction D3. Alternatively, all of the connection portions 23, 24, 25 may be configured to intersect at an angle with respect to the first outer frame portion 21 and the second outer frame portion 22 when viewed in the third direction D3.

[0154] (W) Furthermore, in the manufacturing method of the hall device 10 according to the above embodiment, the hall device unit 7 is rotated in a state in which the mounting portion V2a is attached to the hall device unit 7 so that the hall device unit 7 changes from a horizontal orientation to a vertical orientation. However, the manufacturing method of the hall device 10 is not limited to this method.

[0155] For example, the hall device unit 7 may be transported from the opening W4a of the second hall (reference hall) W4 to the opening W5a of the first hall (attachment hall) W5 while maintaining a horizontal orientation. Alternatively, for example, the hall device unit 7 may be transported from the opening W4a of the second hall (reference hall) W4 to the opening W5a of the first hall (attachment hall) W5 while maintaining a vertical orientation.

[0156] (X) Furthermore, in the hall device unit 7 according to the above embodiment, the outer frame portions 21, 22 are configured to be arranged outward from the ends of the threshold portion 14 and the header portion 15 in the first direction D1. That is, the outer frame portions 21, 22 are configured to be arranged outward from the ends of the hall device 10 in the first direction D1 (first horizontal direction X1). However, the hall device unit 7 is not limited to such a configuration.

[0157] For example, the outer frame portions 21, 22 may be configured to be disposed more inward than the ends of the threshold portion 14 and the header portion 15 in the first direction D1. That is, for example, the outer frame portions 21, 22 may be configured to be disposed more inward than the ends of the hall device 10 in the first direction D1 (first horizontal direction X1).

[0158] (Y) Furthermore, the hall device unit 7 according to the above embodiment is configured to include the hall device 10 and the jig 20 that is removably attached to the hall device 10.

[0159] (Z) Furthermore, in the manufacturing method of the hall device 10 according to the above embodiment, when the hall device 10 (10a, 10b) is fixed to the frame W3b (W6b, W7b), the entire outer frame portions 21, 22 are disposed inside the elevator shaft W1 (i.e., outside the opening 3a) (see FIGS. 3, 5, and 15 to 17). However, the manufacturing method of the hall device 10 is not limited to this method.

[0160] For example, as shown in Fig. 18, when the hall device 10 is fixed to the skeleton W3b, at least a part of the outer frame portions 21, 22 (only the first outer frame portion 21 is shown in Fig. 18) may be disposed inside the opening W3a (i.e., overlapping with the skeleton W3b when viewed in the vertical direction Z1). Note that in Fig. 18, a part of the outer frame portions 21, 22 is disposed inside the opening W3a, but the present invention is not limited to this method, and for example, the entire outer frame portions 21, 22 may be disposed inside the opening W3a.

[0161] Furthermore, in order to position a portion of the outer frame portions 21, 22 inside the opening W3a, for example, the length of the outer frame portions 21, 22 in the second direction D2 may be changed. Although not particularly limited, for example, as shown in FIG. 18 , the length of the outer frame portions 21, 22 in the second direction D2 may be made shorter than the height of the opening W3a in the vertical direction Z1, and the second end portions 21f of the outer frame portions 21, 22 may be positioned above the threshold bracket 16.

[0162] 18, the first end holes 21a of the outer frame portions 21, 22 may be disposed inside the elevator shaft X1 (outside the opening W3a). According to this method, for example, with the wire V1 attached to the first end holes 21a of the outer frame portions 21, 22 (see FIG. 6(a)), it is easy to dispose a portion of the outer frame portions 21, 22 inside the opening W3a.
