Description

Technical Field

[0001] The present invention relates to a car body and an elevator.

Background Art

[0002] In recent years, there has been a shortage of elevator installation technicians. In addition, with the reform of the working style, reduction of overtime work of installation technicians has been attempted. Therefore, improvement in productivity per installation technician is required.

[0003] An elevator is basically assembled on-site where all components including the car are installed. The car is composed of two main parts: a car body and a platform that functions as a load-bearing structure of the car body. The car body has a car floor, side plates (front, rear, left, and right surfaces), a ceiling, a door machine, etc. installed on the car floor.

[0004] When assembling the car body, a plurality of divided side plates are carried onto the car floor one by one, and each side plate is arranged at a predetermined position. Then, after adjusting the positions (alignment) of adjacent side plates, each side plate is fixed to the car floor and the ceiling with screws. Thus, the assembly work of each side plate of the car body requires installation, tilt adjustment, and screw fastening at multiple locations (side plate side surfaces and upper and lower surfaces), so it requires skill and labor. Therefore, to improve productivity per installation technician, it is effective to improve the workability of the car assembly work.

[0005] Patent Document 1 describes a car assembly structure in which a wall panel is erected and fixed on the periphery of a floor panel in a hoistway space. The car body described in Patent Document 1 has side plates erected and fixed on the long side of the car floor on its periphery, and the half panels divided left and right are pivotally connected via a vertical rotation axis. This side plate is carried in through the access opening in a folded state and erected and fixed in an extended state.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, the elevator and the elevator according to the embodiments of the present invention will be described. In each figure, common parts are denoted by the same reference numerals.

[0013] 1. First Embodiment [Elevator] First, the configuration of the elevator according to the first embodiment will be described with reference to FIG. 1. FIG. 1 is an overall configuration diagram of the elevator according to the first embodiment.

[0014] As shown in FIG. 1, the elevator 1 is installed in a hoistway 110 formed in a building structure. The elevator 1 includes a car 120 for carrying people and luggage, a main rope 130, a counterweight 140, and a hoist 150.

[0015] A machine room 160 is formed at the top of the hoistway 110. The elevator according to the present invention is not limited to an elevator having a machine room, and may be a so-called machine-roomless elevator that does not have a machine room above the hoistway 110.

[0016] The hoisting machine 150 is located in the machine room 160. The main rope 130 is wound around the hoisting machine 150. The hoisting machine 150 is a device that winds up the main rope 130 in order to raise and lower the elevator car 120. A deflection wheel 151 is installed near the hoisting machine 150. The main rope 130 is mounted on the deflection wheel 151.

[0017] The elevator car 120 has a hollow, roughly rectangular cage chamber (see Figure 2). The elevator car 120 is connected to a counterweight 140 via a main rope 130. The hoisting machine 150 raises and lowers the elevator car 120 and the counterweight 140 in a bucket-and-loop fashion via the main rope 130. The hoisting machine 150 is driven by a control unit (not shown).

[0018] [Riding car] Next, the configuration of the elevator car 120 according to the first embodiment will be described with reference to Figure 2. Figure 2 is a front view showing the exterior of the elevator car 120.

[0019] In this embodiment, the forward / backward, up / down, and left / right directions are defined based on the line of sight of the elevator user facing the elevator car 120. In this case, from the elevator user's perspective, the front is forward, the back is backward, the top is up, the bottom is down, the left is left, and the right is right. The up / down direction is the same as the vertical direction.

[0020] As shown in Figure 2, the elevator car 120 comprises a car frame 2, a car compartment 3 located inside the car frame 2, a control panel 9, and a car door (not shown).

[0021] The elevator car 3 has an internal storage space for carrying luggage and people. The elevator car 3 has a car floor 4, side panel modules 5, and a ceiling 6. The car floor 4 and ceiling 6 face each other in the vertical direction via the aforementioned storage space. The side panel modules 5 are arranged to surround the storage space on all four sides, except for the car door portion.

[0022] The cage frame 2 is formed as a vertically elongated rectangle when viewed from the front or back. The cage frame 2 is arranged to surround the cage compartment 3. The cage frame 2 has an upper frame 11 positioned above the cage compartment 3, a lower frame 12 positioned below the cage compartment 3, and a pair of vertical frames 13A and 13B positioned on the left and right sides of the cage compartment 3. Multiple cage lower pulleys 7 are rotatably supported on the lower frame 12. The main rope 130 (see Figure 1) is hung on the multiple cage lower pulleys 7.

[0023] [Basket room] Next, the configuration of the elevator car 3 according to the first embodiment will be described with reference to Figure 3. Figure 3 is a perspective view of the elevator car 3 with the ceiling 6 (see Figure 2) and the car door removed.

[0024] As shown in Figure 3, the cage floor 4 of the cage compartment 3 has a floor body 41 and a floor frame 42. The floor body 41 is formed in the shape of a rectangular plate with an appropriate thickness. The floor body 41 has long sides that face each other in the left-right direction and short sides that face each other in the front-back direction.

[0025] The floor frame 42 is positioned at the edge of the upper surface of the floor body 41. The floor frame 42 is formed in a roughly rectangular frame shape by vertically erected plate bodies (thin plates). A door cutout 43 is also formed on the front side of the floor frame 42.

[0026] The lower parts of the side plates 51-54 of the side plate module 5, described later, are in contact with the floor frame 42 and fixed using screws. In other words, the floor frame 42 serves as both a positioning part for positioning the side plate module 5 and a fixing part for fixing the side plate module 5. This reduces the number of parts in the cage floor 4.

[0027] The floor frame 42 has a plurality of screw threading portions 44. The plurality of screw threading portions 44 are, for example, screw holes formed in the floor frame 42. Alternatively, the plurality of screw threading portions 44 may be nuts welded to the outer surface of the floor frame 42 (forming screw through holes in the floor frame 42). Screws for fixing the side plate module 5 to the floor frame 42 (hereinafter referred to as "side plate fixing screws") are screwed into the plurality of screw threading portions 44.

[0028] The side panel module 5 is retractable into approximately cylindrical shapes and is placed 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 according to the present invention, and the rear side panel 54 corresponds to the second side panel according to the present invention. The right side panel 52 corresponds to the third side panel according to the present invention, and the left side panel 53 corresponds to the fourth side panel according to the present invention.

[0029] The front panel 51, right panel 52, left panel 53, and rear panel 54 are each formed in the shape of a vertically elongated rectangular plate. The front panel 51 and rear panel 54 are approximately the same size and face each other in the front-to-back direction. The right panel 52 and left panel 53 are approximately the same size and face each other in the left-to-right direction. The shorter sides of the front panel 51 and rear panel 54 are shorter than the shorter sides of the right panel 52 and left panel 53.

[0030] Both ends of the front panel 51 are connected to one end of the right panel 52 and the left panel 53 via vertically extending pivot fittings 59. Therefore, the front panel 51 is rotatable horizontally around the pivot fittings 59 relative to the right panel 52 and the left panel 53. The pivot fittings 59 can be, for example, hinges.

[0031] Recesses are formed on the inner side of the lower ends of the front side plate 51, right side plate 52, left side plate 53, and rear side plate 54. As a result, thin sections are formed at the lower ends of the front side plate 51, right side plate 52, left side plate 53, and rear side plate 54. Screw holes are formed in the thin sections of each side plate 51-54 through which screws for fixing the side plates pass. The screws for fixing the side plates pass through the thin sections of each side plate 51-54 from the inside of the elevator car 3 and are screwed into the screw threaded sections 44 of the floor frame 42. Therefore, workers can perform the fixing work of each side plate 51-54 from the inside of the elevator car 3.

[0032] Multiple screw threading portions 55 are provided at the upper ends of the front side plate 51, the right side plate 52, the left side plate 53, and the rear side plate 54. These multiple screw threading portions 55 are, for example, screw holes formed in the front side plate 51, the right side plate 52, the left side plate 53, and the rear side plate 54. Alternatively, the multiple screw threading portions 55 may be nuts welded to the outer surfaces of the front side plate 51, the right side plate 52, the left side plate 53, and the rear side plate 54 (forming screw through holes in the side plates 51-54). Screws for fixing the ceiling 6 to the side plate module 5 (hereinafter referred to as "ceiling fixing screws") pass through the multiple screw threading portions 55.

[0033] The front panel 51 has a front panel 51A and a front panel 51B. Front panel 51A and front panel 51B are each formed as vertically elongated rectangular plates and are adjacent to each other in the left-right direction. Door cutouts are formed in front panel 51A and front panel 51B.

[0034] A control panel 9 is mounted on the front panel 51A. The control panel 9 is a so-called vertical control panel. The control panel 9 passes through an opening formed in the front panel 51A. The control panel 9 has an operating section that faces the inside of the elevator car 3. Multiple destination floor buttons, open buttons, close buttons, etc., are arranged on the operating section.

[0035] The horizontally parallel short sides of front panel 51A and front panel 51B are set to a length (size) that divides the front side plate 51 approximately in the horizontal direction. The adjacent long sides of front panel 51A and front panel 51B are connected via a rotating shaft fitting 59 that extends vertically. As a result, the front side plate 51 is formed to be foldable between the right side plate 52 and the left side plate 53 with a simple structure.

[0036] Both 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 vertically extending pivot fittings 59. Therefore, the rear side plate 54 is rotatable horizontally around the pivot fittings 59 relative to the right side plate 52 and the left side plate 53. The rear side plate 54 has a rear panel 54A and a rear panel 54B. The rear panel 54A and the rear panel 54B are each formed as vertically elongated rectangular plates and are adjacent to each other in the left-right direction.

[0037] The horizontally parallel short sides of rear panel 54A and rear panel 54B are set to a length (size) that divides the rear side plate 54 approximately in the horizontal center. The adjacent long sides of rear panel 54A and rear panel 54B are connected via a vertically extending rotating shaft fitting 59. As a result, the rear side plate 54 is formed to be foldable between the right side plate 52 and the left side plate 53 with a simple structure.

[0038] The horizontal (short side) length of the front panel 51A and front panel 51B is shorter than half the horizontal (short side) length of the right panel 52 and left panel 53. Similarly, the horizontal (short side) length of the rear panel 54A and rear panel 54B is shorter than half the horizontal (short side) length of the right panel 52 and left panel 53. As a result, when the front panel 51 and rear panel 54 are folded between the right panel 52 and left panel 53, respectively, the front panel 51 and rear panel 54 do not interfere with each other.

[0039] Wirings 57A and 57B are fixed to the front plate 51 and the right plate 52 using binding members. The front plate 51 and the right plate 52 have multiple wiring fixing holes. The binding members pass through the multiple wiring fixing holes. It is preferable that the fixing of wirings 57A and 57B to the front plate 51 and the right plate 52 be removable. This makes it easier to replace wirings 57A and 57B with new wiring. Furthermore, the fixing of wirings 57A and 57B is not limited to binding members, but may also be a duct member (so-called wiring duct) that houses the wirings 57A and 57B.

[0040] One end of wiring 57A is electrically connected to the control panel of control panel 9. The other end of wiring 57A is connected to a wiring connection part 58. For example, a connector can be used as the wiring connection part 58. Alternatively, the wiring connection part 58 may be a relay panel.

[0041] The wiring connection portion 58 of the wiring 57A is connected to wiring (not shown) located below the car floor 4. The portion of the wiring 57A from the other end to a predetermined length (for example, 200 mm) is not fixed to the front side plate 51. This allows the wiring connection portion 58 to be easily connected to the wiring (not shown) located below the car floor 4.

[0042] Wiring 57B extends vertically. Wiring connectors 58 are connected to both ends of wiring 57B. The lower wiring connector 58 of wiring 57B is connected to wiring (not shown) located below the elevator car floor 4. The upper wiring connector 58 of wiring 57B is connected to wiring (not shown) located above the ceiling 6. The wiring located above the ceiling 6 is connected to electrical equipment (e.g., lighting and air conditioners) installed in the elevator car 3.

[0043] Conventionally, wiring was routed from below the car floor 4 along the outer surface of the car compartment 3 and up to the ceiling 6. However, in this embodiment, since it is only necessary to connect the wiring 57B located below the car floor 4 and the wiring located above the ceiling 6, the work of routing the wiring from below the car floor 4 to the ceiling 6 can be reduced. As a result, the work efficiency of assembling the elevator car 120 can be improved.

[0044] The ceiling 6 (see Figure 5) is formed in the shape of a rectangular plate with an appropriate thickness. The ceiling 6 has a rectangular tubular fixing piece that protrudes downward from its periphery. The fixing piece is fitted into the inside of the upper part of the side plate module 5. Tapered portions may be provided at the upper ends of 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 guide the ceiling 6 into the fitting position. This allows the ceiling 6 to be easily fitted into the side plate module 5.

[0045] The fixing piece of the ceiling 6 has multiple screw through holes. Ceiling fixing screws for fixing the ceiling 6 to the side plate module 5 pass through the multiple through holes of the fixing piece. The ceiling fixing screws pass through the fixing piece of the ceiling 6 from the inside of the elevator car 3 and are screwed into the screw threaded portion 55 of the side plate module 5. Therefore, workers can perform the fixing work of the ceiling 6 from the inside of the elevator car 3.

[0046] [Assembly work of the elevator car compartment] Next, the assembly process for cage compartment 3 will be explained with reference to Figures 4 to 12.

[0047] Furthermore, as a prerequisite for assembling the elevator car 3, it is assumed that the elevator car floor 4 is already installed in the elevator shaft 110 and the elevator car frame 2 is already assembled. It is also assumed that a lifting machine is installed in the elevator shaft 110.

[0048] Figure 4 is a flowchart showing the assembly procedure for cage compartment 3. First, the worker brings the ceiling 6 into the elevator shaft 110 from the entrance 111, attaches a wire rope 15 to the ceiling 6, and lifts it with a lifting machine (not shown) (S1). Figure 5 shows the process of bringing the ceiling 6 into the elevator shaft 110 and lifting it.

[0049] Next, the worker carries the side panel module 5, with the front and rear side panels 51 and 54 folded, into the elevator shaft 110 from the entrance 111 and places it on the elevator car floor 4 (S2). Figure 6 shows the process of carrying the side panel module 5 into the elevator shaft 110. As shown in Figure 6, the side panel module 5 can be folded into a plate of appropriate thickness by folding the front and rear side panels 51 and 54. This allows the side panel module 5 to be easily carried in from the entrance 111 (see Figure 5). The right side panel 52 and left side panel 53 of the side panel module 5 placed on the elevator car floor 4 should be positioned approximately parallel to the long side (the side extending in the front-to-back direction) of the elevator car floor 4.

[0050] Next, the worker unfolds the side panel module 5 on the cage floor 4 (S3). This simplifies the assembly of the side panels 51-54. Figure 7 shows the side panel module 5 in the process of being unfolded on the cage floor 4. Figure 8 shows the side panel module 5 after it has been fully unfolded. At this time, if the right side panel 52 and left side panel 53 of the side panel module 5 are positioned approximately parallel to the long side (the side extending in the front-to-back direction) of the cage floor 4, the side panel module 5 will not interfere with the floor frame 42, and the side panel module 5 can be easily unfolded.

[0051] As shown in Figure 8, once the side panel module 5 is fully deployed, the lower parts (thin sections) of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 of the side panel module 5 come into contact with the floor frame 42. This positions the side panel module 5 on the cage floor 4. Therefore, the operator can easily position the side panel module 5 relative to the cage floor 4.

[0052] Next, the worker fixes 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 cage floor 4 using side plate fixing screws (S4). Next, the worker lowers the ceiling 6, which is suspended by the lifting machine, and fits it onto the upper end of the side plate module 5 (S5). Figure 9 shows the state in which the ceiling 6 has been lowered onto the upper end of the side plate module 5. Subsequently, the worker fixes the ceiling 6 to the upper end of the side plate module 5 using ceiling fixing screws (S6).

[0053] Next, the worker installs the door machine, including the car door, electrical equipment, etc., into the car compartment 3 (S7). Subsequently, the worker performs the wiring work for the electrical equipment to be installed in the car compartment 3 (S8). At this time, the worker uses the wiring 57A and 57B that are pre-fixed to the front side plate 51 and the right side plate 52 of the side plate module 5. This improves the work efficiency of the wiring work and shortens the working time for assembling the car compartment 3 compared to conventional methods.

[0054] Figure 10 shows the state before the baseboard is fitted into the lower part of the side panel module 5. As shown in Figure 10, the lower part (thin section) of the side panel module 5 is exposed to the inside of the elevator car 3. Therefore, the screws used to fix the side panel module 5 to the floor frame 42 are visible from the inside of the elevator car 3.

[0055] The worker then inserts the finishing baseboard 30 into the lower part (thin section) of the side panel module 5 (S9). This completes the assembly of the elevator car 3. Figure 11 shows the process of inserting the finishing baseboard 30 into the lower part of the side panel module 5. Figure 12 shows the state after the finishing baseboard 30 has been inserted into the lower part of the side panel module 5.

[0056] As shown in Figure 11, the finishing baseboard 30 is a member with a roughly C-shaped side profile and can be fitted into a recess that forms the thin-walled portion of the side panel module 5. By fitting the finishing baseboard 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 interior appearance of the car compartment 3 can be improved.

[0057] Furthermore, the fixing pieces of the ceiling 6 in this embodiment are exposed on the inside of the elevator car 3. As a result, the screws used to fix the ceiling 6 to the side panel module 5 are visible from the inside of the elevator car 3. Therefore, the worker fits a finishing baseboard (not shown) onto the fixing pieces of the ceiling 6. This covers the connection between the side panel module 5 and the ceiling 6, improving the appearance of the inside of the elevator car 3.

[0058] [Temporary Wheel Unit] The side panel module 5 forms one of the four walls of the elevator car 3, and therefore can be quite heavy. In this case, transporting the side panel module 5 within the building and bringing it into the elevator shaft 110 becomes complicated. To facilitate the transport of the side panel module 5, a temporary wheel unit 60 can be attached to the side panel module 5.

[0059] Next, the configuration and usage of the temporary wheel unit 60 will be explained with reference to Figures 13 and 14. Figure 13 is a perspective view of the temporary wheel unit 60. Figure 14 shows the temporary wheel unit 60 attached to the lower part of the side plate module 5.

[0060] As shown in Figure 13, the temporary wheel unit 60 has an adapter plate 61 and a plurality of casters 62 fixed to the adapter plate 61. The adapter plate 61 is formed in the shape of a rectangular plate with an inner surface that is substantially vertical in the horizontal direction. The plurality of casters 62 are fixed to the lower surface of the adapter plate 61. The adapter plate 61 has a plurality of connection holes 63. Wheel screws (not shown) for fixing the temporary wheel unit 60 to the side plate module 5 pass through the plurality of connection holes 63.

[0061] As shown in Figure 14, the temporary wheel unit 60 is attached to the lower part of the side plate module 5 by utilizing the screw holes (screw holes through which screws for fixing the side plates pass) in the right side plate 52 and left side plate 53 of the side plate module 5. In other words, the lower part of the side plate module 5 is a connection part to which the temporary wheel unit 60 can be attached and detached.

[0062] Here, we will specifically explain how the temporary wheel unit 60 is connected to the lower part of the side plate module 5. First, the adapter plate 61 of the temporary wheel unit 60 is placed 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 holes in the right side plate 52 and the left side plate 53 and the multiple connection holes 63 in the adapter plate 61, and nuts are screwed on.

[0063] By attaching a temporary wheel unit 60 to the lower part of the side panel module 5, workers can carry the side panel module 5 with less force. This allows the side panel module 5 to be easily transported onto the cage floor 4.

[0064] The procedure for removing the temporary wheel unit 60 from the side plate module 5 is as follows: First, the worker slightly lifts the side plate module 5 with a lifting machine. Alternatively, a wire rope 15 chain block attached to the ceiling 6 may be used to lift the side plate module 5 using the chain block.

[0065] Next, the worker removes the temporary wheel unit 60 from the side panel module 5 and unfolds the side panel module 5. After that, the worker lowers the side panel module 5 and places it on the cage floor 4. Note that the side panel module 5 may also be unfolded after it has been placed on the cage floor 4.

[0066] 2. Second Embodiment The difference between the elevator according to the second embodiment and the elevator 1 according to the first embodiment lies in the structure of the elevator car. Therefore, the structure of the elevator car according to the second embodiment will be described here, and the description of the configuration that overlaps with the first embodiment will be omitted.

[0067] [Basket room] The configuration of the elevator car 3A according to the second embodiment will be described with reference to Figure 15. Figure 15 is a perspective view of elevator car 3A.

[0068] As shown in Figure 15, the elevator car 3A has an elevator car floor 4, a side panel module 5, and a ceiling 6. The difference between the elevator car 3A and the elevator car 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.

[0069] The left side end of the ceiling 6 is connected to the upper end of the left side panel 53 of the side panel module 5 via a rotating shaft fitting (not shown) that extends in the front-rear direction. Therefore, the ceiling 6 can rotate vertically around the rotating shaft fitting 59 relative to the left side panel 53 and can be positioned between the right side panel 52 and the left side panel 53. This allows the side panel module 5 and the ceiling 6 to be made into a single assembly part, and further improves the workability of the assembly process. Hereinafter, the assembly of the side panel module 5 with the ceiling 6 connected will be referred to as the car module 10.

[0070] To fold the elevator car module 10, first, the ceiling 6 is positioned between the right-side panel 52 and the left-side panel 53. This causes the inner surface of the ceiling 6 to face 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 ceiling 6. This folds the elevator car module 10.

[0071] [Assembly work of the elevator car compartment] Next, the assembly process for elevator car 3A will be explained with reference to Figures 16 to 21.

[0072] Furthermore, as a prerequisite for assembling the elevator car 3A, it is assumed that the elevator car floor 4 is already installed in the elevator shaft 110 and the elevator car frame 2 is already assembled. It is also assumed that a lifting machine is installed in the elevator shaft 110.

[0073] Figure 16 is a flowchart showing the procedure for assembling elevator car 3A. First, the worker carries the folded elevator car module 10 into the elevator shaft 110 through the entrance 111 and places it on the elevator car floor 4 (S11).

[0074] Figure 17 shows the state immediately before the elevator car module 10 is moved into the hoistway 110. Figure 18 shows the state after the elevator car module 10 has been moved into the hoistway 110. As shown in Figures 17 and 18, the elevator car module 10 can be made entirely of a plate of appropriate thickness. This allows the elevator car module 10 to be easily moved in through the entrance / exit 111.

[0075] Next, the worker unfolds the elevator car module 10 on the elevator car floor 4 (S12). Figure 19 shows the side panel module 5 in the process of being unfolded on the elevator car floor. Figure 20 shows the side panel module 5 after it has been fully unfolded.

[0076] As shown in Figure 20, once the side panel module 5 is fully deployed, the lower parts (thin sections) of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 of the side panel module 5 come into contact with the floor frame 42. This positions the side panel module 5 on the cage floor 4. Therefore, the operator can easily position the side panel module 5 relative to the cage floor 4.

[0077] Next, the worker fixes the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 of the side panel module 5 to the floor frame 42 of the cage floor 4 using side panel fixing screws (S13). Next, the worker attaches the wire rope 15 to the ceiling 6 facing the left side panel 53 and lifts the ceiling 6 with a lifting machine (S14). Figure 21 shows the ceiling 6 of the cage module 10 being lifted with a lifting machine.

[0078] When the ceiling 6 is raised, the four end faces of the ceiling 6 face the upper parts of the front side panel 51, right side panel 52, left side panel 53, and rear side panel 54 of the side panel module 5, and the outer and inner surfaces of the ceiling 6 become parallel to the horizontal direction (see Figure 15). Next, the worker fixes the ceiling 6 to the upper end of the side panel module 5 using ceiling fixing screws (S15).

[0079] Next, the worker installs the door machine, including the car door, electrical equipment, etc., into the car compartment 3 (S16). Subsequently, the worker performs the wiring work for the electrical equipment to be installed in the car compartment 3 (S17). At this time, the worker uses the wiring 57A and 57B that are pre-fixed to the front side plate 51 and the right side plate 52 of the side plate module 5. This improves the work efficiency of the wiring work and shortens the working time for assembling the car compartment 3A compared to conventional methods.

[0080] Next, the worker inserts the finishing baseboard 30 (see Figures 11 and 12) into the lower part (thin section) of the side panel module 5 (S18). This completes the assembly of the elevator car 3A. By inserting the finishing baseboard 30 into the lower part (thin section) of the side panel module 5, the connection between the side panel module 5 and the elevator car floor 4 is covered, and the interior appearance of the elevator car 3 is completed.

[0081] The embodiments of the elevator car and elevator of the present invention, including their effects, have been described above. However, the elevator car and elevator of the present invention are not limited to the embodiments described above, and various modifications can be made without departing from the gist of the invention as described in the claims.

[0082] Furthermore, the embodiments described above are explained in detail for the purpose of clearly illustrating the present invention, and are not necessarily limited to those comprising all the described configurations. It is also possible to replace parts of the configuration of one embodiment with those of another embodiment, and to add configurations from other embodiments to the configuration of one embodiment. Additionally, it is possible to add, delete, or replace parts of the configuration of each embodiment with those of other embodiments.

[0083] In the first and second embodiments described above, the front side plate 51 and the rear side plate 54 were made into a split structure and made foldable between the right side plate 52 and the left side plate 53. However, in the side plate module according to the present invention, the right side plate and the left side plate may also be made into a split structure and made foldable between the front side plate and the rear side plate. In this case, the folded right side plate and the left side plate should not interfere with each other. Furthermore, the split structure of the side plate is not limited to two divisions, but can also be an even number of divisions such as four or six divisions that can be folded.

[0084] In the first and second embodiments described above, the floor frame 42 was formed in a substantially rectangular frame shape using vertically erected plates (thin plates). However, the cage floor according to the present invention may also have a floor frame for fixing a plurality of side plates and a positioning part that engages with the plurality of side plates to position the side plate modules. In this case, the positioning part can be formed by vertically erected thin plates or pins.

[0085] Furthermore, in the first and second embodiments described above, the wiring 57A and 57B were fixed to the front side plate 51 and the right side plate 52. However, the quantity and fixing position of the wiring according to the present invention can be set as appropriate.

[0086] In this specification, although terms such as "parallel" and "orthogonal" are used, these do not mean only strictly "parallel" and "orthogonal," but may also refer to states that are "approximately parallel" or "approximately orthogonal," which include "parallel" and "orthogonal" and are within a range in which they can perform their functions.
