Specifically, the lower frame 10 is disposed parallel to the left-right direction, and each of the floor support beams 14A, 14B is disposed parallel to the front-rear direction.

[0024] A car door 18 is provided at the front of the car chamber 8. The car door 18 is provided so as to be openable and closable in the left-right direction. A pair of under-car pulleys 4A, 4B are arranged below the car chamber 8 (see FIG. 1 for 4B). The under-car pulleys 4A, 4B are arranged forward of the vertical frames 11A, 11B. One under-car pulley 4A is attached to a floor support beam 14A, and the other under-car pulley 4B is attached to a floor support beam 14B.

[0025] [Vibration isolation section] Next, the configuration of the vibration isolation unit 20 will be described with reference to FIGS. Fig. 3 is an explanatory diagram showing a pair of floor support beams 14A, 14B. Fig. 4 is a perspective view of the car floor 12 as viewed from below.

[0026] The vibration-proof section 20 has four coil springs 20A shown in FIG. 3, a first spring base 20B attached to the bottom surfaces of the floor support beams 14A and 14B, and a second spring base 20C attached to the bottom surface of the car floor 12 shown in FIG. 4.

[0027] As shown in FIG. 3, the coil spring 20A is an elastic member for vibration isolation. The first spring seat 20B and the second spring seat 20C are plate-shaped members. The first spring seat 20B is provided with four spring receiving holes (not shown) for receiving one ends of the four coil springs 20A. The spring receiving holes of the first spring seat 20B are formed in a circular shape. The diameter of the spring receiving hole of the first spring seat 20B is larger than the diameter of the coil spring 20A. The gap between the spring receiving hole of the first spring seat 20B and the coil spring 20A is set to a size necessary for adjusting the position of the car chamber 8.

[0028] As shown in Fig. 4, the second spring seat 20C is provided with four spring receiving holes 20D that receive the other ends of the four coil springs 20A. The spring receiving holes 20D are formed in a circular shape. The diameter of the spring receiving holes 20D is set to be approximately the same as the diameter of the coil springs 20A. The coil springs 20A fit into the spring receiving holes 20D and move together with the second spring seat 20C and the cage 8.

[0029] As shown in Fig. 3, the car floor 12 has a rectangular floor member 12A. The two short sides of the floor member 12A are approximately perpendicular to the front-rear direction, and the two long sides of the floor member 12A are approximately perpendicular to the left-right direction. A cage sill 12B is attached to one of the short sides of the floor member 12A facing forward. The cage sill 12B faces a hatch sill (not shown) provided in the hoistway 100 at a predetermined distance.

[0030] A floor frame member 12C is provided on the short side of the floor member 12A facing rearward. Furthermore, floor frame members 12D and 12E are provided on the two long sides of the floor member 12A, respectively. The lower portions of the three side plates 13, excluding the side plate 13 to which the car door 18 is attached, are fixed to the surfaces (inner surfaces) of the floor frame members 12C to 12D on the storage space side.

[0031] The car chamber 8 is supported by a pair of floor support beams 14A, 14B via vibration isolation parts 20. This suppresses vibration of the car chamber 8. The car 3 also has a pair of vibration prevention parts 31A, 31B (see FIG. 5) that suppress vibration of the car chamber 8 in the front-to-rear direction. The pair of vibration prevention parts 31A, 31B also serve as a position adjustment mechanism for the car chamber 8. The configuration of the pair of vibration prevention parts 31A, 31B will be described later with reference to FIG. 5 and FIG. 6.

[0032] [A pair of vertical frames] Next, the configuration of the pair of vertical frames 11A, 11B will be described with reference to FIG. FIG. 5 is a perspective view of the car 3 with the ceiling 15 and side panels 13 removed.

[0033] As shown in Fig. 5, the vertical frame 11A has a vertical frame main body 21, a connecting member 22, and a fitting portion 23. The vertical frame main body 21 extends long in the up-down direction. The vertical frame main body 21 has two side portions 21A, 21B facing each other in the front-rear direction, and a main body plate 21C continuing to the two side portions 21A, 21B. The main body plate 21C faces the car chamber 8. The two side portions 21A, 21B protrude substantially perpendicularly from both side ends of the main body plate 21C toward the opposite side to the car chamber 8.

[0034] The connecting member 22 is disposed directly above the car under pulley 4A, and connects the vertical frame 11A and the floor support beam 14A. The connecting member 22 is made of a bent member, like the vertical frame main body 21. The upper end of the connecting member 22 is set at approximately the same height as the lower surface of the car floor 12. The connecting member 22 is fixed to the side portion 21A of the vertical frame main body 21 using a bolt (screw). The connecting member 22 is also fixed to the floor support beam 14A via an intermediate member 24.

[0035] The fitting portion 23 is an integral structure obtained by bending a metal plate. The fitting portion 23 is fixed to the lower part of the vertical frame main body 21. The fitting portion 23 has a pair of wall plates facing each other in the front-rear direction, and a bottom plate having a flat surface that is approximately perpendicular to the up-down direction. One end of the lower frame 10 (see FIG. 5) in the longitudinal direction is fitted into the fitting portion 23 from above.

[0036] The vertical frame 11B has a vertical frame body 25, a connecting member 26, and a fitting portion 27 (see FIG. 3). The vertical frame body 25 has the same configuration as the vertical frame body 21 of the vertical frame 11A described above, and has two side portions 25A, 25B, and a body plate 25C that is continuous with the two side portions 25A, 25B.

[0037] The connecting member 26 is disposed directly above the car under pulley 4B (see FIG. 3), and connects the vertical frame 11B and the floor support beam 14B (see FIG. 3). The connecting member 26 is made of a bent member, like the vertical frame main body 21. The upper end of the connecting member 26 is higher than the upper surface of the car floor 12. The connecting member 26 is fixed to the side portion 25A of the vertical frame main body 25 using a bolt (screw). The connecting member 26 is also fixed to the floor support beam 14B via an intermediate member (not shown).

[0038] The fitting portion 27 has the same shape as the fitting portion 23 of the vertical frame 11A described above. The fitting portion 27 is fixed to the lower portion of the vertical frame main body 25. The fitting portion 27 has a pair of wall panels facing each other in the front-rear direction, and a bottom panel having a flat surface that is approximately perpendicular to the up-down direction. One end of the lower frame 10 (see FIG. 5) in the longitudinal direction is fitted into the fitting portion 27 from above.

[0039] [A pair of anti-vibration parts] Next, the pair of vibration prevention portions 31A, 31B of the cage 8 will be described with reference to FIGS. FIG. 6 is an explanatory diagram showing an enlarged view of a part of the side surface of the car 3 with the ceiling 15 and the side panel 13 removed.

[0040] 5 and 6, the vibration prevention portion 31A includes a rubber plate 32 as an elastic body, and a metal bracket 33 that supports the rubber plate 32. The rubber plate 32 is formed in an L-shape. The rubber plate 32 represents one specific example of a rubber member according to the present invention.

[0041] The bracket 33 of the anti-sway portion 31A is disposed forward of the vertical frame 11A in the front-rear direction. The bracket 33, like the rubber plate 32, is formed in an L shape and has a fixed portion 33a fixed to the car chamber 8 and an opposing portion 33b opposing the vertical frame 11A of the car frame 7 in the front-rear direction.

[0042] The fixing portion 33a of the bracket 33 is fixed to the floor frame member 12D of the car floor 12 by two bolts 37. The screw through holes of the fixing portion 33a through which the two bolts 37 pass are formed in a substantially elliptical shape that is elongated in the horizontal direction. The rubber plate 32 is interposed between the facing portion 33b and the vertical frame 11A, and between the car chamber 8 and the vertical frame 11A. The facing portion 33b of the bracket 33 presses the rubber plate 32 against the side portion 21A of the vertical frame 11A.

[0043] The anti-sway portion 31B has the same configuration as the anti-sway portion 31A, and includes a rubber plate 35 and a bracket 36. The rubber plate 35 represents one specific example of a rubber member according to the present invention. The bracket 36 of the anti-sway portion 31B is disposed rearward in the front-rear direction from the vertical frame 11A. The bracket 36 has a fixed portion 36a fixed to the car chamber 8 and an opposing portion 36b opposing the vertical frame 11A of the car frame 7 in the front-rear direction.

[0044] The fixing portion 36a of the bracket 36 is fixed to the floor frame member 12D of the car floor 12 by two bolts 37. The screw through holes of the fixing portion 36a through which the two bolts 37 pass are formed in a substantially elliptical shape that is elongated in the horizontal direction. The rubber plate 35 is interposed between the facing portion 36b and the vertical frame 11A, and between the car chamber 8 and the vertical frame 11A. The facing portion 36b of the bracket 36 presses the rubber plate 35 against the side portion 21B of the vertical frame 11A.

[0045] The car 3 has a position adjustment mechanism for adjusting the position of the car 3 with respect to the car frame 7 (see FIG. 2). The position adjustment mechanism is composed of the above-mentioned brackets 33, 36 and two jack bolts 34. The two jack bolts 34 penetrate the opposing parts 33b, 36b of the brackets 33, 36 and abut against the side parts 21A, 21B of the vertical frame 11A, respectively.

[0046] When the tip of the jack bolt 34 penetrating the facing portion 33b of the bracket 33 is pushed into the side portion 21A of the vertical frame 11A, the length of the gap generated between the facing portion 33b and the side portion 21A increases. As a result, the car chamber 8 moves forward relative to the vertical frame 11A (car frame 7). On the other hand, when the tip of the jack bolt 34 penetrating the facing portion 36b of the bracket 36 is pushed into the side portion 21B of the vertical frame 11A, the length of the gap generated between the facing portion 36b and the side portion 21B increases. As a result, the car chamber 8 moves backward relative to the vertical frame 11A (car frame 7).

[0047] [Installation of car seats] Next, the installation work of the car 3 will be described. The lower frame 10 of the car 3, the pair of floor support beams 14A, 14B, and the car floor 12 are assembled together and transported to the installation site as a car lower assembly.

[0048] When assembling the car lower assembly in a factory or the like, the bottom surface of the car floor 12 is turned upward, and the second spring seat 20C is attached to the bottom surface. Then, one end of the coil spring 20A is inserted into the spring receiving hole 20D of the second spring seat 20C.

[0049] Next, the pair of floor support beams 14A, 14B to which the first spring base 20B is attached are placed above the car floor 12, and the other end of the coil spring 20A is inserted into the spring receiving hole of the first spring base 20B. Next, the car floor 12 and the pair of floor support beams 14A, 14B are temporarily fixed with a temporary fixing member (not shown). Next, the car lower assembly is turned upside down so that the car floor 12 faces upward.

[0050] The diameter of the spring receiving hole 20D is set to be approximately the same as the diameter of the coil spring 20A. Therefore, when the other end of the coil spring 20A is inserted into the spring receiving hole of the first spring seat 20B, the position of the coil spring 20A is prevented from shifting. As a result, the assembly work of the car lower assembly can be performed efficiently.

[0051] When installing the car 3, first, the pair of vertical frames 11A, 11B are attached to a guide rail (not shown). At this time, the pair of vertical frames 11A, 11B are fixed to the guide rail. Then, after assembling the car 3, the car frame 7 is made movable relative to the guide rail.

[0052] Next, the car lower assembly is placed above the fitting parts 23, 27 of the pair of vertical frames 11A, 11B. Then, the car lower assembly is lowered so that both longitudinal ends of the lower frame 10 are fitted into the fitting parts 23, 27 of the pair of vertical frames 11A, 11B. Next, the lower frame 10 is fixed to the fitting parts 23, 27 using bolts (screws). This allows the car lower assembly to be attached to the pair of vertical frames 11A, 11B.

[0053] Next, the four side panels 13 are fixed to the car floor 12, and the ceiling 15 is fixed onto the four side panels 13. This completes the assembly of the car room 8 (see FIG. 2). Next, both longitudinal ends of the upper frame 9 are fixed to the upper ends of the vertical frames 11A and 11B using bolts (screws). This completes the assembly of the car frame 7, and the installation of the car 3 is completed.

[0054] [Adjusting the position of the car] Next, the position adjustment operation of the car 3 will be described. The position adjustment work of the car 3 may be performed on the car floor 12 when the car lower assembly is attached to the pair of vertical frames 11A, 11B, or may be performed after the car 3 is assembled.

[0055] The car 3 is supported by a pair of floor support beams 14A, 14B via four vibration-proofing parts 20. The pair of floor support beams 14A, 14B are supported by the lower frame 10 of the car frame 7. As described above, the vibration-proofing part 20 has a coil spring 20A, a first spring base 20B attached to the floor support beams 14A, 14B, and a second spring base 20C attached to the car floor 12. The diameter of the spring receiving hole of the first spring base 20B is larger than the diameter of the coil spring 20A. Therefore, the car 3 can be moved horizontally without lifting the car 3 relative to the floor support beams 14A, 14B.

[0056] When adjusting the position of the car 3, first remove the rubber plates 32, 35 (see FIG. 6) of the pair of anti-sway portions 31A, 31B. Then, when moving the car 3 forward, push the tip of the jack bolt 34 penetrating the bracket 33 into the side portion 21A of the vertical frame 11A. At this time, the tip of the jack bolt 34 penetrating the bracket 36 is kept away from the side portion 21B of the vertical frame 11A. This causes the car 3 to move forward.

[0057] On the other hand, when moving the car 3 rearward, the tip of the jack bolt 34 penetrating the bracket 36 is pushed into the side 21B of the vertical frame 11A. At this time, the tip of the jack bolt 34 penetrating the bracket 33 is kept away from the side 21A of the vertical frame 11A. This causes the car 3 to move rearward. By pushing in the jack bolt 34 in this way, the car 3 (car floor 12) can be easily moved, and the position of the car 3 in the fore-and-aft direction can be easily adjusted.

[0058] After adjusting the position of the car 3, the brackets 33, 36 are removed from the car floor 12. Next, the rubber plate 32 is interposed between the facing portion 33b of the bracket 33 and the side portion 21A of the vertical frame 11A. Then, the bracket 33 is placed in a position where the facing portion 33b presses the rubber plate 32 against the side portion 21A, and the fixing portion 33a of the bracket 33 is fixed to the car floor 12 using two bolts 37.

[0059] Further, a rubber plate 35 is interposed between the opposing portion 36b of the bracket 36 and the side portion 21B of the vertical frame 11A. Then, the bracket 36 is disposed at a position where the opposing portion 36b presses the rubber plate 35 against the side portion 21B, and the fixing portion 36a of the bracket 36 is fixed to the car floor 12 using two bolts 37. This makes it possible to suppress vibration of the car 3 in the front-rear direction.

[0060] The jack bolt 34 may be stored together with the car 3 while passing through the brackets 33, 36, or may be removed from the brackets 33, 36 and stored separately from the car 3.

[0061] 2. Summary As described above, the car 3 of the above-mentioned embodiment includes the car chamber 8, the car frame 7, the floor support beams 14A, 14B (support beams), the brackets 33, 36, and the jack bolt 34. The car chamber 8 has the side plates 13 surrounding the four sides in the left-right direction and the front-rear direction when viewed from the boarding side of the building. The car frame 7 surrounds the car chamber 8 in the four sides in the left-right direction and the up-down direction. The floor support beams 14A, 14B are fixed to the car frame 7 and support the car chamber 8. The brackets 33, 36 have fixing parts 33a, 36a fixed to the car chamber 8 and facing parts 33b, 36b facing the car frame 7 in the front-rear direction. The jack bolt 34 penetrates the facing parts 33b, 36b of the brackets 33, 36 and abuts against the car frame 7. This allows the car 3 to be easily moved in the forward and backward directions, and the position of the car 3 can be easily adjusted.

[0062] Moreover, the car chamber 8 in the above-described embodiment has the car floor 12 and the ceiling 15 that face each other in the vertical direction, and the fixing parts 33a, 36a of the brackets 33, 36 are fixed to the car floor 12. This allows the car 3 to be stably moved when adjusting the position of the car 3. Also, the car 3 can be assembled after adjusting the position of the car floor 12, making it easier to adjust the position of the car 3.

[0063] The car 3 in the above-described embodiment further includes a vibration-isolating unit 20 interposed between the floor support beams 14A, 14B (support beams) and the car floor 12. The vibration-isolating unit 20 includes a first spring pedestal 20B (first pedestal) provided on the floor support beams 14A, 14B, a second spring pedestal 20C (second pedestal) provided on the car floor 12, and a coil spring 20A (elastic member) interposed between the first spring pedestal 20B and the second spring pedestal 20C (second pedestal). The first spring pedestal 20B has a spring receiving hole (receiving portion) that receives the coil spring 20A movably in the horizontal direction. The second spring pedestal 20C has a spring receiving hole 20D (receiving portion) that receives the coil spring 20A so that it cannot move in the horizontal direction. This allows the car 3 to be moved horizontally without being lifted relative to the floor support beams 14A and 14B.

[0064] Moreover, the car frame 7 in the above-described embodiment has an upper frame 9 arranged at the upper part of the car chamber 8, a lower frame 10 arranged at the lower part of the car chamber 8, and a pair of vertical frames 11A, 11B arranged on the left and right sides of the car chamber 8. The floor support beams 14A, 14B (support beams) are fixed to the lower frame 10. The opposing parts 33b, 36b of the brackets 33, 36 face the vertical frame 11A. This allows an operator to operate the jack bolts 34 without entering under the car floor 12. As a result, the safety of the position adjustment work of the car 3 can be improved.

[0065] Moreover, the car 3 in the above-described embodiment further includes rubber plates 32, 35 (rubber members) that are interposed between the opposing parts 33b, 36b and the car frame 7 after the position of the car chamber 8 is adjusted. This allows the brackets 33, 36, which are part of the position adjustment mechanism, to also function as the anti-sway parts 31A, 31B. As a result, it is possible to easily adjust the position of the car 3 in the front-rear direction and reduce the number of parts.

[0066] Moreover, the car 3 in the above-described embodiment has a bracket 33 (first bracket) and a bracket 36 (second bracket). The car 3 also has a jack bolt 34 (first jack bolt) penetrating the opposing portion 33b of the bracket 33, and a jack bolt 34 (second jack bolt) penetrating the opposing portion 36b of the bracket 36. The opposing portion 33b faces a surface (side portion 21A) of the car frame 7 facing forward in the front-to-rear direction, and the opposing portion 36b faces a surface (side portion 21B) of the car frame 7 facing backward in the front-to-rear direction. This allows the car 3 to be easily moved forward and backward.

[0067] The car and elevator of the present invention have been described above, including their effects. However, the car and elevator of the present invention are not limited to the above-mentioned embodiment, and various modifications can be made without departing from the spirit of the invention described in the claims.

[0068] For example, in the above-described embodiment, the brackets 33, 36 of the position adjustment mechanism are fixed to the floor frame member 12D of the car floor 12. However, the car according to the present invention may be configured so that the brackets of the position adjustment mechanism are fixed to the floor frame member 12E. Also, the position adjustment mechanism according to the present invention may be configured so that it is provided on both sides (floor frame members 12D, 12E) in the left-right direction of the car.

[0069] In the above-described embodiment, a coil spring is used as the elastic member of the vibration-proofing section 20. However, other spring members such as leaf springs or rubber members can also be used as the elastic member of the vibration-proofing section according to the present invention.

[0070] In addition, the above-described embodiment is configured to be able to move the car 3 in the horizontal direction without lifting the car by providing a plurality of vibration-proofing parts 20. However, the car position adjustment mechanism according to the present invention can also be applied to a car that can be moved in the forward and backward directions by being lifted relative to the floor support beam.
