Description

Technical Field

[0001] This invention relates to the car cabin and elevators. Background Technology

[0002] In recent years, there has been a shortage of skilled elevator installers. Furthermore, reforms in work methods are seeking to reduce the extra-hour work of these installers. Therefore, there is a need to improve the productivity of each installer.

[0003] Elevators are basically assembled entirely on-site, including the car. The car consists of two main parts: the car compartment and the platform that functions as the load-bearing structure of the car compartment. The car compartment includes the car floor, side panels (front, back, left, and right surfaces) installed on the car floor, the ceiling, and the door operator.

[0004] During the assembly of the car cabin, the multiple, pre-divided side panels are moved one by one onto the car floor, positioning each panel in its designated place. Then, after adjusting (aligning) the positions of adjacent side panels, they are secured to the car floor and ceiling using screws. This assembly process requires setting up, tilting and adjusting, and tightening screws on multiple parts (side panels and upper and lower surfaces), thus demanding skill and labor. Therefore, improving the workability of the car cabin assembly process is effective in increasing the productivity of each worker.

[0005] Patent Document 1 describes a car assembly structure in which a fixed wall panel is erected on the periphery of the floor panel within the hoistway space. In the car compartment described in Patent Document 1, a side panel erected on the long side of the car floor and fixed to its periphery is pivotally connected to a panel divided into left and right halves via a longitudinal rotation axis. This side panel is moved in from the entrance / exit opening in a folded state and erected and fixed in an extended state.

[0006] However, the car compartment described in Patent Document 1 is constructed by dividing the side panel that forms one side. Therefore, the improvement in workability is limited, as it only improves the workability of assembling the side panel of the divided structure.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2006-273431 Summary of the Invention

[0008] In view of the above problems, the object of the present invention is to provide a car and elevator that can improve the workability of assembly operations.

[0009] To address the aforementioned issues and achieve the objectives of this invention, one aspect of the invention reflects a car compartment comprising a car floor, a ceiling, and side panel modules fixed to the car floor and ceiling. The side panel modules have a first side panel and a second side panel facing each other, and a third side panel and a fourth side panel facing each other. The two ends of the first side panel are connected to one end of the third and fourth side panels in a manner rotatable about a rotation axis extending vertically. The two ends of the second side panel are connected to the other end of the third and fourth side panels in a manner rotatable about a rotation axis extending vertically. The first and second side panels are formed between the third and fourth side panels in a foldable manner.

[0010] An elevator reflecting one aspect of the present invention includes a car that moves up and down within a shaft, the car having the aforementioned car compartment.

[0011] The car cabin and elevator with the above structure can improve the workability of the assembly operation.

[0012] Furthermore, the issues, structures, and effects other than those described above will be clarified through the following description of the implementation methods. Attached Figure Description

[0034] The following describes the car and elevator according to embodiments of the present invention. Furthermore, common components are labeled with the same reference numerals in all figures.

[0035] 1. First Implementation Method

[0036] [elevator]

[0037] First, refer to Figure 1The structure of the elevator in Embodiment 1 will be described.

[0038] Figure 1 This is an overall structural diagram of the elevator according to implementation method 1.

[0039] like Figure 1 As shown, elevator 1 is installed in a shaft 110 formed within a building structure. Elevator 1 includes a car 120 for carrying people and goods, a main rope 130, a counterweight 140, and a traction machine 150.

[0040] A machine room 160 is formed at the top of the shaft 110. Furthermore, the elevator of the present invention is not limited to an elevator with a machine room; it can also be a so-called machine room-less elevator that does not have a machine room above the shaft 110.

[0041] A traction machine 150 is located in the machine room 160. A main rope 130 is wound on the traction machine 150. The traction machine 150 is a device for winding the main rope 130 to raise and lower the car 120. A guide pulley 151 is provided near the traction machine 150. The main rope 130 is strung on the guide pulley 151.

[0042] The car 120 has a car compartment that is hollow and generally rectangular in shape (see reference). Figure 2 The car 120 is connected to the counterweight 140 via the main rope 130. The traction machine 150 raises and lowers the car 120 and the counterweight 140 in a bucket-like manner via the main rope 130. The drive of the traction machine 150 is controlled by a control unit (not shown).

[0043] [Elevator Car]

[0044] Next, refer to Figure 2 The structure of the car 120 in the first embodiment will be described.

[0045] Figure 2 This is the front view showing the exterior of the car 120.

[0046] In this embodiment, the front-back, up-down, and left-right directions are defined based on the line of sight of the elevator user opposite the car 120. In this case, from the elevator user's perspective, the side closer to the front is the front, the side further in is the back, the upper side is the upper, the lower side is the lower, the left side is the left, and the right side is the right. In addition, the up-down direction is the same as the vertical direction.

[0047] like Figure 2 As shown, the car 120 has a car frame 2, a car compartment 3 disposed inside the car frame 2, an operating panel 9, and a car door (not shown).

[0048] The car compartment 3 has internal storage space for loading goods and passengers. The car compartment 3 has a car floor 4, side panel modules 5, and a ceiling 6. The car floor 4 and ceiling 6 are positioned opposite each other in the vertical direction, separated by the aforementioned storage space. The side panel modules 5, except for the car door portion, are arranged to surround the aforementioned storage space.

[0049] The car frame 2 is a longitudinally elongated rectangle when viewed from the front-to-back direction. The car frame 2 is configured to surround the car compartment 3. The car frame 2 has an upper frame 11 located above the car compartment 3, a lower frame 12 located below the car compartment 3, and a pair of longitudinal frames 13A and 13B located on the left and right sides of the car compartment 3. Multiple car pulleys 7 are rotatably supported on the lower frame 12. A main rope 130 (see reference) is wound around the multiple car pulleys 7. Figure 1 ).

[0050] [Elevator Cabin]

[0051] Next, refer to Figure 3 The structure of the car room 3 in the first embodiment will be described.

[0052] Figure 3 Remove the canopy 6 from car compartment 3 (see reference) Figure 2 A 3D view of the car door and its status.

[0053] like Figure 3 As shown, the car floor 4 of the car compartment 3 has a floor body 41 and a floor frame 42. The floor body 41 is formed into a rectangular plate with an appropriate thickness. The floor body 41 has long sides opposite each other in the left-right direction and short sides opposite each other in the front-back direction.

[0054] The floor frame 42 is disposed on the edge of the upper surface of the floor body 41. The floor frame 42 is formed into a generally rectangular frame shape from a plate (thin plate) that is erected vertically. In addition, a door cutout 43 is formed on the front side of the floor frame 42.

[0055] The lower parts of the side panels 51-54 of the side panel module 5 (described later) abut against the floor frame 42 and are fixed with screws. That is, the floor frame 42 serves as both a positioning part for positioning the side panel module 5 and a fixing part for fixing the side panel module 5. As a result, the number of parts of the car floor 4 can be reduced.

[0056] The floor frame 42 has a plurality of screw engagement portions 44. The plurality of screw engagement portions 44 are, for example, screw holes formed in the floor frame 42. Alternatively, the plurality of screw engagement portions 44 may be nuts welded to the outer surface of the floor frame 42 (with screw through holes formed in the floor frame 42). Screws (hereinafter referred to as "side panel fixing screws") for fixing the side panel module 5 to the floor frame 42 are screwed into the plurality of screw engagement portions 44.

[0057] The side panel module 5 can be unfolded into a generally cylindrical shape and disposed on the floor body 41. The side panel module 5 has a front side panel 51, a right side panel 52, a left side panel 53, and a rear side panel 54. The front side panel 51 corresponds to the first side panel of the present invention, and the rear side panel 54 corresponds to the second side panel of the present invention. The right side panel 52 corresponds to the third side panel of the present invention, and the left side panel 53 corresponds to the fourth side panel of the present invention.

[0058] The front side plate 51, right side plate 52, left side plate 53, and rear side plate 54 are each formed into a rectangular plate that is longer in the vertical direction. The front side plate 51 and rear side plate 54 are approximately the same size and are opposite each other in the front-back direction. The right side plate 52 and left side plate 53 are approximately the same size and are opposite each other in the left-right direction. The shorter side of the front side plate 51 and rear side plate 54 is shorter than the shorter side of the right side plate 52 and left side plate 53.

[0059] Both ends of the front side panel 51 are connected to one side of the right side panel 52 and the left side panel 53 via a rotating shaft fitting 59 extending vertically. Therefore, the front side panel 51 can rotate horizontally relative to the right side panel 52 and the left side panel 53 about the rotating shaft fitting 59. The rotating shaft fitting 59 can be, for example, a hinge.

[0060] Recesses are formed on the inner sides of the lower ends of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54. This creates thin-walled portions at the lower ends of these panels. Screw holes are formed in the thin-walled portions of each side panel 51-54 for screws used to fix the side panels. Screws for fixing the side panels pass through the thin-walled portions of each side panel 51-54 from the inside of the car compartment 3 and engage with the screw threaded portion 44 of the floor frame 42. Therefore, the operator can perform fixing operations on each side panel 51-54 from the inside of the car compartment 3.

[0061] Multiple screw engagement portions 55 are provided at the upper ends of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54. These multiple screw engagement portions 55 are, for example, screw holes formed in the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54. Alternatively, the multiple screw engagement portions 55 may be nuts (with screw through holes formed in the side panels 51-54) welded to the outer surfaces of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54. Screws (hereinafter referred to as "ceiling fixing screws") used to fix the canopy 6 to the side panel module 5 pass through the multiple screw engagement portions 55.

[0062] The front panel 51 has a front panel 51A and a front panel 51B. The front panel 51A and the front panel 51B are each formed as a rectangular plate that is longer in the vertical direction and are adjacent in the left-right direction. Door cutouts are formed on the front panel 51A and the front panel 51B.

[0063] An operating panel 9 is mounted on the front panel 51A. The operating panel 9 is a so-called vertical operating panel. The operating panel 9 is formed through the opening in the front panel 51A. The operating panel 9 has an operating section facing the inside of the car compartment 3. Multiple destination floor buttons, open buttons, close buttons, etc. are arranged in the operating section.

[0064] The short sides of the front panels 51A and 51B, which are parallel to the horizontal direction, are configured to divide the length (size) of the front side panel 51 approximately at the center in the horizontal direction. The adjacent long sides of the front panels 51A and 51B are connected via a swivel fitting 59 extending in the vertical direction. Thus, the front side panel 51 is foldably formed between the right side panel 52 and the left side panel 53 with a simple construction.

[0065] The two ends of the rear side plate 54 are connected to the other ends of the right side plate 52 and the left side plate 53 via rotating shaft fittings 59 extending vertically. Therefore, the rear side plate 54 can rotate horizontally relative to the right side plate 52 and the left side plate 53 about the rotating shaft fittings 59. The rear side plate 54 has a rear panel 54A and a rear panel 54B. The rear panels 54A and 54B are each formed as rectangular plates that are longer in the vertical direction and are adjacent to each other in the left-right direction.

[0066] The short sides of the rear panels 54A and 54B, parallel to the horizontal direction, are configured to divide the length (size) of the rear side panel 54 approximately at the center in the horizontal direction. The adjacent long sides of the rear panels 54A and 54B are connected via a swivel fitting 59 extending in the vertical direction. Thus, the rear side panel 54 is foldably formed between the right side panel 52 and the left side panel 53 with a simple construction.

[0067] The horizontal (short side) lengths of the front panels 51A and 51B are half the horizontal (short side) lengths of the right side panel 52 and left side panel 53. Similarly, the horizontal (short side) lengths of the rear panels 54A and 54B are half the horizontal (short side) lengths of the right side panel 52 and left side panel 53. Therefore, when the front side panel 51 and the rear side panel 54 are folded between the right side panel 52 and the left side panel 53 respectively, the front side panel 51 and the rear side panel 54 will not interfere with each other.

[0068] Wiring 57A and 57B are secured to the front side panel 51 and the right side panel 52 using bundling components. The front side panel 51 and the right side panel 52 have multiple wiring securing holes. The bundling components pass through these holes. The securing of wiring 57A and 57B to the front side panel 51 and the right side panel 52 is preferably detachable. This facilitates the replacement of wiring 57A and 57B with new wiring. Furthermore, the securing of wiring 57A and 57B is not limited to bundling components; it can also be achieved using conduit components (so-called wiring conduits) to house wiring 57A and 57B.

[0069] One end of wiring 57A is electrically connected to the operation panel of operation panel 9. A wiring connector 58 is connected to the other end of wiring 57A. For example, a connector can be used as the wiring connector 58. Alternatively, a relay panel can also be used as the wiring connector 58.

[0070] The wiring connection portion 58 of wiring 57A is connected to a wiring device (not shown) disposed below the car floor 4. The portion of wiring 57A extending to a predetermined length (e.g., 200 mm) is not fixed to the front side panel 51. Therefore, the wiring connection portion 58 can be easily connected to the wiring device (not shown) disposed below the car floor 4.

[0071] Wiring 57B extends vertically. Wiring connection portions 58 are connected to both ends of wiring 57B. The lower wiring connection portion 58 of wiring 57B connects to a wiring (not shown) disposed below the car floor 4. The upper wiring connection portion 58 of wiring 57B connects to a wiring (not shown) disposed above the ceiling 6. The wiring disposed above the ceiling 6 connects, for example, to electrical equipment (e.g., lighting, air conditioning, etc.) installed in the car compartment 3.

[0072] Conventionally, wiring is pulled up from below the car floor 4, along the outer surface of the car compartment 3, towards the ceiling 6. However, in this embodiment, wiring 57B can be connected only to the wiring located below the car floor 4 and the wiring located above the ceiling 6, thus reducing the work of pulling wiring up from below the car floor 4 to above the ceiling 6. As a result, the workability of assembling the car 120 can be improved.

[0073] Ceiling 6 (reference) Figure 5 The canopy 6 is formed into a rectangular plate with appropriate thickness. The canopy 6 has a square-tube-shaped fixing piece protruding downwards from its periphery. The fixing piece fits into the inner side of the upper part of the side panel module 5. Alternatively, tapered portions guiding the canopy 6 to the fitting position can be provided at the upper ends of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 in the side panel module 5. This allows the canopy 6 to be easily fitted into the side panel module 5.

[0074] The mounting plate of the ceiling 6 has multiple through holes for screws. A ceiling fixing screw for securing the ceiling 6 to the side panel module 5 passes through these through holes. The ceiling fixing screw passes through the mounting plate of the ceiling 6 from the inside of the car compartment 3 and engages with the screw threaded portion 55 of the side panel module 5. Therefore, the operator can perform the ceiling 6 fixing operation from the inside of the car compartment 3.

[0075] [Assembly work of the car compartment]

[0076] Next, refer to Figures 4-12 The assembly operation of the car compartment 3 is explained.

[0077] Furthermore, as a prerequisite for assembling the car compartment 3, the car floor 4 is inserted into the hoistway 110, and the car frame 2 is in a fully assembled state. Additionally, a crane is installed within the hoistway 110.

[0078] Figure 4 This is a flowchart showing the steps involved in assembling the car compartment 3.

[0079] First, the operator moves the canopy 6 from the entrance 111 into the shaft 110, hangs the steel cable 15 on the canopy 6, and lifts it with a crane (not shown) (S1). Figure 5 This diagram shows the process of moving the ceiling 6 into the shaft 110 and lifting it.

[0080] Next, the operator moves the side panel module 5, with the front side panel 51 and the rear side panel 54 folded, from the entrance / exit 111 into the hoistway 110 and places it on the car floor 4 (S2). Figure 6 This diagram illustrates the process of moving the side panel module 5 into the shaft 110. (See diagram for example.) Figure 6 As shown, the side panel module 5 can fold the front side panel 51 and the rear side panel 54 to form a panel of appropriate thickness. Therefore, the side panel module 5 can be easily accessed from the entrance 111 (see reference 111). Figure 5 The right side panel 52 and left side panel 53 of the side panel module 5, which is placed on the car floor 4, can be positioned approximately parallel to the long side (the side extending in the front-to-back direction) of the car floor 4.

[0081] Next, the operator unfolds the side panel module 5 on the car floor 4 (S3). This simplifies the assembly of the side panels 51-54. Figure 7 This diagram shows the state of the side panel module 5 during its unfolding on the car floor 4. Figure 8 This diagram shows the state in which the side panel module 5 is fully unfolded. At this time, if the right side panel 52 and the left side panel 53 of the side panel module 5 are positioned approximately parallel to the long side (the side extending in the front-rear direction) of the car floor 4, the side panel module 5 can be made to not interfere with the floor frame 42 and can be easily unfolded.

[0082] like Figure 8 As shown, when the side panel module 5 is fully deployed, the lower parts (thin-walled portions) of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 in the side panel module 5 abut against the floor frame 42. Thus, the side panel module 5 is positioned relative to the car floor 4. Therefore, the operator can easily position the side panel module 5 relative to the car floor 4.

[0083] Next, the operator uses side plate fixing screws to fix the front side plate 51, right side plate 52, left side plate 53, and rear side plate 54 of the side plate module 5 to the floor frame 42 of the car floor 4 (S4). Then, the operator lowers the canopy 6, which is lifted by the crane, so that it fits into the upper end of the side plate module 5 (S5). Figure 9 This diagram shows the state where the canopy 6 has descended to the upper end of the side panel module 5. Next, the operator uses canopy fixing screws to fix the canopy 6 to the upper end of the side panel module 5 (S6).

[0084] Next, the operator installs the door operator, electrical equipment, and other components, including the car door, into the car compartment 3 (S7). Then, the operator performs wiring work on the electrical equipment installed in the car compartment 3 (S8). At this time, the operator uses wiring 57A and 57B, which are pre-fixed to the front side panel 51 and right side panel 52 of the side panel module 5. This improves the workability of the wiring work and shortens the assembly time of the car compartment 3 compared to previous methods.

[0085] Figure 10 This diagram shows the state before the decorative baseboard is embedded in the lower part of side panel module 5. (See diagram for example.) Figure 10 As shown, the lower part (thin-walled part) of the side panel module 5 is exposed inside the car compartment 3. Therefore, the side panel fixing screws used to fix the side panel module 5 to the floor frame 42 can be seen from the inside of the car compartment 3.

[0086] Therefore, the operator inserts the decorative kick plate 30 into the lower part (thin-walled part) of the side panel module 5 (S9). Thus, the assembly of the car chamber 3 is completed. Figure 11 This diagram shows the case where a decorative kickboard 30 is embedded in the lower part of the side panel module 5. Figure 12 This diagram shows the state in which a decorative kickboard 30 is embedded in the lower part of the side panel module 5.

[0087] like Figure 11 As shown, the decorative skirting board 30 is a component with a roughly C-shaped side profile, which can be inserted into the recess for forming the thin-walled portion of the side panel module 5. By inserting the decorative skirting board 30 into the lower part (thin-walled portion) of the side panel module 5, the connection between the side panel module 5 and the car floor 4 can be covered, and the shape of the inner side of the car compartment 3 can be adjusted.

[0088] Furthermore, in this embodiment, the fixing plate of the ceiling 6 is exposed inside the car compartment 3. Therefore, ceiling fixing screws for fixing the ceiling 6 to the side panel module 5 can be seen from the inside of the car compartment 3. Therefore, the operator inserts a decorative skirting board (not shown) into the fixing plate of the ceiling 6. As a result, the connection between the side panel module 5 and the ceiling 6 can be covered, and the shape of the inside of the car compartment 3 can be adjusted.

[0089] [Temporary wheel unit]

[0090] The side panel modules 5 form the four walls of the car compartment 3, thus increasing their weight. This complicates the transport of the side panel modules 5 within the building and their insertion into the hoistway 110. Therefore, to facilitate the transport of the side panel modules 5, temporary wheel units 60 can be installed on them.

[0091] Next, refer to Figure 13 and Figure 14 The structure and usage of the temporary wheel unit 60 are explained.

[0092] Figure 13 This is a three-dimensional view of the temporary wheel unit 60. Figure 14 This diagram shows the state in which a temporary wheel unit 60 is installed at the lower part of the side panel module 5.

[0093] like Figure 13 As shown, the temporary wheel unit 60 has a connecting plate 61 and a plurality of casters 62 fixed to the connecting plate 61. The connecting plate 61 is formed into a rectangular plate with an inner surface that is substantially perpendicular to the horizontal direction. The plurality of casters 62 are fixed to the lower surface of the connecting plate 61. The connecting plate 61 has a plurality of connecting holes 63. Wheel screws (not shown) for fixing the temporary wheel unit 60 to the side plate module 5 pass through the plurality of connecting holes 63.

[0094] like Figure 14 As shown, the temporary wheel unit 60 is installed on the lower part of the side plate module 5 using the screw through holes (screw through holes for screws used to fix the side plates) in the right side plate 52 and left side plate 53 of the side plate module 5. That is, the lower part of the side plate module 5 is a connecting part that allows the temporary wheel unit 60 to be installed and removed.

[0095] Here, the connection of the temporary wheel unit 60 to the lower part of the side plate module 5 will be specifically described. First, the connecting plate 61 of the temporary wheel unit 60 is positioned between the lower part of the right side plate 52 and the lower part of the left side plate 53. Then, wheel screws (bolts) are passed through the screw through holes of the right side plate 52 and the left side plate 53 and the multiple connecting holes 63 of the connecting plate 61, and nuts are screwed in.

[0096] By installing temporary wheel units 60 on the lower part of the side panel module 5, the operator can transport the side panel module 5 with less force. As a result, the side panel module 5 can be easily moved onto the car floor 4.

[0097] The steps for removing the temporary wheel unit 60 from the side panel module 5 are as follows. First, the operator uses a crane to slightly lift the side panel module 5. Alternatively, a chain trolley with steel cable 15 suspended on the ceiling 6 can be installed to lift the side panel module 5.

[0098] Next, the operator removes the temporary wheel unit 60 from the side panel module 5 and unfolds the side panel module 5. Afterwards, the operator lowers the side panel module 5 and places it on the car floor 4. Alternatively, the side panel module 5 can be unfolded after being placed on the car floor 4.

[0099] 2. Second Implementation Method

[0100] The elevator in the second embodiment differs from the elevator 1 in the first embodiment in the structure of the car compartment. Therefore, the structure of the car compartment in the second embodiment will be described here, omitting the description of structures that are repeated in the first embodiment.

[0101] [Elevator Cabin]

[0102] Reference Figure 15 The structure of the car room 3A in the second embodiment will be described.

[0103] Figure 15 This is a 3D view of car room 3A.

[0104] like Figure 15 As shown, the car compartment 3A has a car floor 4, a side panel module 5, and a ceiling 6. The difference between the car compartment 3A and the car compartment 3 of the first embodiment is that the ceiling 6 is rotatably connected to the left side panel 53 of the side panel module 5.

[0105] The left end of the canopy 6 is connected to the upper end of the left side plate 53 in the side plate module 5 via a rotating shaft fitting (not shown) extending in the front-rear direction. Therefore, the canopy 6 can rotate vertically relative to the left side plate 53 about the rotating shaft fitting 59, and can be positioned between the right side plate 52 and the left side plate 53. This allows the side plate module 5 and the canopy 6 to be assembled as a single unit, further improving the workability of the assembly process. Hereinafter, the component with the canopy 6 connected to the side plate module 5 will be referred to as the car compartment module 10.

[0106] With the car compartment module 10 in a folded state, firstly, the roof 6 is positioned between the right side panel 52 and the left side panel 53. Thus, the inner surface of the roof 6 faces the inner surface of the left side panel 53. Next, the front side panel 51 and the rear side panel 54 are folded and positioned between the right side panel 52 and the roof 6. Thus, the car compartment module 10 is folded.

[0107] [Assembly work of the car compartment]

[0108] Next, refer to Figures 16-21 The assembly operation of the car compartment 3A is explained.

[0109] Furthermore, as a prerequisite for assembling the car room 3A, the car floor 4 is inserted into the hoistway 110, and the car frame 2 is in a fully assembled state. Additionally, a crane is installed within the hoistway 110.

[0110] Figure 16 This is a flowchart showing the steps involved in assembling the car compartment 3A.

[0111] First, the operator moves the folded car room module 10 from the entrance / exit 111 into the hoistway 110 and places it on the car floor 4 (S11).

[0112] Figure 17 This diagram shows the state before the car compartment module 10 is moved into the hoistway 110. Figure 18 This diagram shows the state in which the car compartment module 10 is moved into the hoistway 110. (Example) Figure 17 and Figure 18 As shown, the car compartment module 10 can be designed as a plate of appropriate thickness. Therefore, the car compartment module 10 can be easily moved in from the entrance / exit 111.

[0113] Next, the operator unfolds the car room module 10 on the car floor 4 (S12). Figure 19 This is a diagram showing the side panel module 5 being deployed on the car floor in the middle of its unfolding process. Figure 20 This is a diagram showing the state of the side panel module 5 after it has been fully unfolded.

[0114] like Figure 20 As shown, when the side panel module 5 is fully deployed, the lower parts (thin-walled portions) of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 in the side panel module 5 abut against the floor frame 42. Thus, the side panel module 5 is positioned relative to the car floor 4. Therefore, the operator can easily position the side panel module 5 relative to the car floor 4.

[0115] Next, the operator uses side plate fixing screws to fix the front side plate 51, right side plate 52, left side plate 53, and rear side plate 54 of the side plate module 5 to the floor frame 42 of the car floor 4 (S13). Next, the operator hangs the steel cable 15 on the canopy 6 opposite to the left side plate 53 and uses a crane to lift the canopy 6 (S14). Figure 21 This diagram shows the case where the roof 6 of the car compartment module 10 is lifted by a crane.

[0116] When the ceiling 6 is lifted, the four corner faces of the ceiling 6 are aligned with the upper parts of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 in the side panel module 5. The outer and inner surfaces of the ceiling 6 are parallel to the horizontal direction (see reference). Figure 15 Next, the operator uses ceiling fixing screws to fix the ceiling 6 to the upper end of the side panel module 5 (S15).

[0117] Next, the operator installs the door operator, electrical equipment, and other components, including the car door, into the car compartment 3 (S16). Then, the operator performs wiring work on the electrical equipment installed in the car compartment 3 (S17). At this time, the operator uses wiring 57A and 57B, which are pre-fixed to the front side panel 51 and right side panel 52 of the side panel module 5. This improves the workability of the wiring work and shortens the assembly time of the car compartment 3A compared to previous methods.

[0118] Next, the workers will decorate the baseboard 30 (refer to...). Figure 11 as well as Figure 12 The decorative kick plate 30 is embedded in the lower part (thin-walled part) of the side panel module 5 (S18). Thus, the assembly of the car compartment 3A is completed. By embedding the decorative kick plate 30 in the lower part (thin-walled part) of the side panel module 5, the connection between the side panel module 5 and the car floor 4 can be covered, adjusting the inner shape of the car compartment 3.

[0119] The embodiments of the car room and elevator of the present invention have been described above, including their effects. However, the car room and elevator of the present invention are not limited to the above embodiments, and various modifications can be made within the scope of the spirit of the invention as described in the claims.

[0120] Furthermore, the embodiments described above are detailed for the purpose of easily understanding and illustrating the present invention, and are not limited to having all the structures described. Additionally, a portion of the structure of one embodiment can be replaced with a structure of another embodiment, and structures of other embodiments can be added to the structure of one embodiment. Furthermore, regarding a portion of the structure of each embodiment, other structures can be added, deleted, or replaced.

[0121] In the first and second embodiments described above, the front side panel 51 and the rear side panel 54 are configured as separate structures, allowing them to be folded between the right side panel 52 and the left side panel 53. However, as the side panel module of the present invention, the right side panel and the left side panel can also be configured as separate structures, allowing them to be folded between the front side panel and the rear side panel. In this case, the folded right side panel and the left side panel do not interfere with each other. Furthermore, the side panel's separation structure is not limited to two separations; it can also be configured as an even number of separations, such as four or six separations, that allow for folding.

[0122] In the first and second embodiments described above, the floor frame 42 is formed into a generally rectangular frame shape by a plate (thin plate) erected vertically in the vertical direction. However, as the car floor of the present invention, it may also have a floor frame for fixing multiple side plates and a positioning part for engaging with the multiple side plates to position the side plate modules. In this case, the positioning part can be formed by a thin plate or pin erected vertically in the vertical direction.

[0123] Furthermore, in the first and second embodiments described above, wiring 57A and 57B are fixed to the front side plate 51 and the right side plate 52. However, the number and fixing positions of the wiring in this invention can be appropriately set.

[0124] Furthermore, the terms “parallel” and “orthogonal” are used in this specification, but they do not only refer to strict “parallel” and “orthogonal”. They can also refer to a state of “approximately parallel” or “approximately orthogonal” that includes “parallel” and “orthogonal” and is within the range where it can perform its function.
