Description

The present invention relates to cars and elevators.

An elevator car comprises a car chamber and a car frame that supports the car chamber. The car chamber has a floor, a ceiling, and side panels. The car frame is disposed outside the car chamber and is formed into a rectangular frame that surrounds the floor, ceiling, and side panels. The car frame movably engages with guide rails provided in the hoistway.

Patent Document 1 describes a technique for assembling a car. Generally, after assembling the car in the elevator, the distance between the elevator hatch sill and the car cage sill may differ between the left and right sides. In this case, the position of the car is adjusted by moving the entire car chamber relative to the car frame.

JP 2004-196488 A

By the way, to adjust the position of the car after the passenger car has been assembled, first remove the vibration-isolating rubber that connects the floor of the car (car floor) to the bottom frame of the car frame. Next, the entire car is lifted using a jack bolt attached to the bottom frame. After that, a worker pushes the car to adjust its position. Therefore, adjusting the position of the car requires a lot of work time.

Taking into consideration the above problems, the objective of this invention is to provide a car and elevator that allows the position of the car chamber relative to the elevator shaft to be easily adjusted.

In order to solve the above problems and achieve the object, the elevator car includes a car chamber, a car frame, a support beam, a bracket, and a jack bolt. The car chamber has side panels that surround the car chamber on all four sides in the left-right and front-back directions when viewed from the boarding side of the building. The car frame surrounds the car chamber on all four sides in the left-right and up-down directions. The support beam is fixed to the car frame and supports the car chamber. The bracket has a fixed portion fixed to the car chamber and an opposing portion that faces the car frame in the front-back direction. The jack bolt passes through the opposing portion of the bracket and abuts against the car frame. The car chamber has a car floor and a ceiling that face each other in the up-down direction. The fixed portion of the bracket is fixed to the car floor.
The elevator also includes the car that moves up and down within the elevator shaft.

According to the car and elevator having the above configuration, the position of the car room relative to the hoistway can be easily adjusted.
Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same functions or configurations are designated by the same reference numerals, and duplicated descriptions will be omitted.

1. Embodiment [Elevator]
First, the configuration of an elevator according to one embodiment of the present invention will be described with reference to FIG.
FIG. 1 is a schematic configuration diagram of an elevator according to one embodiment.

As shown in Figure 1, the elevator includes a hoist 1, a main rope 2, a car 3, a counterweight 5, and a pulley 6. The car 3 includes a pair of under-car pulleys 4A, 4B. The car 3 moves up and down the elevator shaft 100 according to the movement of the main rope 2 wound around the pair of under-car pulleys 4A, 4B.

The hoist 1 is a device that winds up the main rope 2 to raise and lower the car 3. The hoist 1 is installed at the top of the hoistway 100. One end and the other end of the main rope 2 are fixed to the top of the hoistway 100. The main rope 2 is wound around a pair of under-car pulleys 4A, 4B, the hoist 1, and a pulley 6.

The car 3 rises and falls while being guided by a pair of guide rails (not shown). A pair of under-car pulleys 4A, 4B are arranged below the car 3. The counterweight 5 is a weight for reducing the load on the hoist 1 by balancing the mass with the car 3. When the hoist 1 winds up the main rope 2, the counterweight 5 rises and falls in the opposite direction to the car 3. The pulley 6 is arranged above the counterweight 5 and rises and falls together with the counterweight 5.

[Car]
Next, the configuration of the car 3 will be described with reference to FIG.
FIG. 2 is a perspective view showing the appearance of the car 3. As shown in FIG.

In this embodiment, the front-back, up-down, left-right directions are defined based on the line of sight of the elevator user facing the car 3. In this case, the near side as seen from the elevator user is the forward direction, the far side is the rear, the upper side is the upward direction, the lower side is the downward direction, the left side is the left side, and the right side is the right side.

As shown in Figure 2, the elevator car 3 comprises a car frame 7 and a car chamber 8 arranged inside the car frame 7. The car chamber 8 has an internal storage space for carrying luggage and passengers. The car chamber 8 is formed by a car floor 12, side panels 13, and a ceiling 15. The car floor 12 and the ceiling 15 are arranged to face each other in the vertical direction with the storage space between them. The side panels 13 are arranged to surround all four sides of the storage space, except for the car door 18.

The car frame 7 is formed into a vertically long rectangle when viewed from the front-to-rear direction.

The car frame 7 has an upper frame 9 arranged at the top of the car chamber 8, a lower frame 10 (see Figure 3) arranged at the bottom 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 upper frame 9 is a member that extends elongately in the left-right direction. The upper frame 9 is horizontally suspended between the upper ends of a pair of vertical frames 11A, 11B. One longitudinal end of the upper frame 9 is fixed to the upper end of the vertical frame 11A, and the other longitudinal end of the upper frame 9 is fixed to the upper end of the vertical frame 11B. As a result, the upper ends of the pair of vertical frames 11A, 11B are connected by the upper frame 9.

The pair of vertical frames 11A, 11B are arranged facing each other in the left-right direction. Each of the vertical frames 11A, 11B is a member that extends long in the up-down direction. Each of the vertical frames 11A, 11B is supported movably by the pair of guide rails described above. The guide rails are long members that are installed vertically on the walls of the elevator shaft 100.

The lower frame 10 is disposed in a position facing the upper frame 9 across the cage chamber 8. The lower frame 10 is a roughly rectangular parallelepiped member that extends long in the left-right direction (see FIG. 3). The lower frame 10 is horizontally suspended between the lower ends of a pair of vertical frames 11A, 11B. One longitudinal end of the lower frame 10 is fixed to the lower end of the vertical frame 11A, and the other longitudinal end of the lower frame 10 is fixed to the lower end of the vertical frame 11B. As a result, the lower ends of the pair of vertical frames 11A, 11B are connected by the lower frame 10.

The lower frame 10 supports the car floor 12 via a pair of floor support beams 14A, 14B. The pair of floor support beams 14A, 14B are beams that support the car floor 12. An anti-vibration section 20 is provided at each of both longitudinal ends of the floor support beam 14A, and an anti-vibration section 20 is also provided at each of both longitudinal ends of the floor support beam 14B. The anti-vibration sections 20 are parts that suppress vibrations of the car room 8 including the car floor 12. The car floor 12 is supported by the pair of floor support beams 14A, 14B via multiple (four in this embodiment) anti-vibration sections 20.

The floor support beam 14A is disposed at one end (right end) of the lower frame 10 in the longitudinal direction. The floor support beam 14B is disposed at the other end (left end) of the lower frame 10 in the longitudinal direction (see FIG. 3). Each floor support beam 14A, 14B is fixed to the upper surface of the lower frame 10 by a bolt (not shown) while placed on the lower frame 10. Each floor support beam 14A, 14B is disposed horizontally in a direction perpendicular to the lower frame 10. Specifically, the lower frame 10 is disposed parallel to the left-right direction, and each floor support beam 14A, 14B is disposed parallel to the front-to-rear direction.

A car door 18 is installed at the front of the car chamber 8. The car door 18 is capable of opening and closing in the left-right direction. A pair of under-car pulleys 4A, 4B are arranged below the car chamber 8 (see Figure 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.

[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.

The vibration-proof section 20 has four coil springs 20A as shown in Figure 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 as shown in Figure 4.

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

As shown in FIG. 4, the second spring base 20C has 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 base 20C and the cage chamber 8.

As shown in Figure 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-to-rear direction, and the two long sides of the floor member 12A are approximately perpendicular to the left-to-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 elevator shaft 100 at a predetermined distance.

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

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

[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.

As shown in Figure 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-to-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 approximately vertically from both side ends of the main body plate 21C toward the opposite side to the car chamber 8.

The connecting member 22 is positioned directly above the under-car 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 underside 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.

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 body 21. The fitting portion 23 has a pair of wall plates facing each other in the front-to-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 Figure 5) in the longitudinal direction is fitted into the fitting portion 23 from above.

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.

The connecting member 26 is positioned directly above the under-car 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).

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 body 25. The fitting portion 27 has a pair of wall panels facing each other in the front-to-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 Figure 5) in the longitudinal direction is fitted into the fitting portion 27 from above.

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

5 and 6, the vibration prevention part 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.

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

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 through which the two bolts 37 of the fixing portion 33a 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.

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-to-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-to-rear direction.

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 long 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.

The car 3 has a position adjustment mechanism for adjusting the position of the car 3 relative to the car frame 7 (see FIG. 2). The position adjustment mechanism is composed of the brackets 33, 36 and two jack bolts 34. The two jack bolts 34 pass through the opposing parts 33b, 36b of the brackets 33, 36 and abut against the side parts 21A, 21B of the vertical frame 11A, respectively.

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 between the facing portion 33b and the side portion 21A increases. As a result, the cage chamber 8 moves forward relative to the vertical frame 11A (cage 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 between the facing portion 36b and the side portion 21B increases. As a result, the cage chamber 8 moves backward relative to the vertical frame 11A (cage frame 7).

[Installation of car]
Next, the installation work of the car 3 will be described.
The lower frame 10 of the car 3, a 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.

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 base 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 base 20C.

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 temporary fixing members (not shown). Next, the car lower assembly is turned upside down so that the car floor 12 faces upward.

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 base 20B, the position of the coil spring 20A is not shifted. As a result, the assembly work of the car lower assembly can be performed efficiently.

When installing the car 3, first, a 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.

Next, the car lower assembly is placed above the fitting portions 23, 27 of the pair of vertical frames 11A, 11B. The car lower assembly is then lowered so that both longitudinal ends of the lower frame 10 fit into the fitting portions 23, 27 of the pair of vertical frames 11A, 11B. Next, the lower frame 10 is fixed to the fitting portions 23, 27 using bolts (screws). This attaches the car lower assembly to the pair of vertical frames 11A, 11B.

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 chamber 8 (see Figure 2). Next, both longitudinal ends of the upper frame 9 are fixed to the upper ends of the vertical frames 11A, 11B using bolts (screws). This completes the assembly of the car frame 7, and the installation of the car 3 is completed.

[Cab position adjustment work]
Next, the position adjustment work 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.

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, it is possible to move the car 3 horizontally without lifting the car 3 relative to the floor support beams 14A, 14B.

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

On the other hand, when moving the car 3 rearward, the tip of the jack bolt 34 that penetrates the bracket 36 is pushed into the side 21B of the vertical frame 11A. At this time, the tip of the jack bolt 34 that penetrates 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.

After adjusting the position of the car 3, the brackets 33, 36 are removed from the car floor 12. Next, a 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.

In addition, 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. The bracket 36 is then positioned 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 fore-and-aft direction.

The jack bolt 34 may be stored together with the car 3 while still penetrating the brackets 33, 36, or it may be removed from the brackets 33, 36 and stored separately from the car 3.

2. Summary As described above, the elevator 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 panels 13 that surround the car chamber 8 on all four sides in the left-right and front-back directions when viewed from the boarding side of the building. The car frame 7 surrounds the car chamber 8 on all four sides in the left-right and up-down directions. 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 that are fixed to the car chamber 8, and facing parts 33b, 36b that face the car frame 7 in the front-back 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.

In addition, the car chamber 8 in the above-described embodiment has a car floor 12 and a 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 moved stably when adjusting the position of the car 3. In addition, 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.

In addition, the car 3 in the above-mentioned embodiment further includes a vibration-proofing section 20 interposed between the floor support beams 14A, 14B (support beams) and the car floor 12. The vibration-proofing section 20 has 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. In addition, 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, 14B.

Furthermore, the car frame 7 in the above-described embodiment has an upper frame 9 arranged at the top of the car chamber 8, a lower frame 10 arranged at the bottom 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 portions 33b, 36b of the brackets 33, 36 face the vertical frame 11A. This allows the operator to operate the jack bolts 34 without having to enter under the car floor 12. As a result, the safety of the position adjustment work for the car 3 can be improved.

In addition, 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 fore-aft direction and reduce the number of parts.

Furthermore, 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) that penetrates the facing portion 33b of the bracket 33, and a jack bolt 34 (second jack bolt) that penetrates the facing portion 36b of the bracket 36. The facing portion 33b faces a surface (side portion 21A) of the car frame 7 that faces forward in the fore-and-aft direction, and the facing portion 36b faces a surface (side portion 21B) of the car frame 7 that faces backward in the fore-and-aft direction. This allows the car 3 to be easily moved forward and backward.

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-described embodiment, and various modifications are possible within the scope of the invention as set forth in the claims.

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. In addition, the position adjustment mechanism according to the present invention may be configured so that it is provided on both the left and right sides of the car (floor frame members 12D, 12E).

In addition, the above-described embodiment employs a coil spring 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.

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 multiple vibration isolation parts 20. However, the car position adjustment mechanism according to the present invention can also be applied to a car that can be moved forward and backward by lifting it relative to the floor support beam.

The above-mentioned embodiment has been described in detail to clearly explain the present invention, and is not necessarily limited to having all of the configurations described. In addition, it is possible to add, delete, or replace part of the configuration of the embodiment with other configurations.

In this specification, the words "parallel" and "orthogonal" are used, but these do not mean only "parallel" and "orthogonal" in the strict sense, but also include "parallel" and "orthogonal" and may also refer to a state of "approximately parallel" or "approximately orthogonal" within the range in which the functions can be exerted.
