The vertical frames 22A and 22B each face two guide rails 170 (one is omitted in FIG. 2) installed in the hoistway 110 (see FIG. 1). The two guide rails 170 extend in the vertical direction. The two guide rails 170 guide the car 2 in the vertical direction (elevating direction).

The upper portions of the vertical frames 22A, 22B are connected to the upper frame 23 using a connecting member 37, which will be described later. Moreover, four raising members 31 are connected to the vertical frames 22A, 22B and the upper frame 23 using screws.

The upper frame 23 extends in the left-right direction. The cross-sectional shape of the upper frame 23 perpendicular to the left-right direction is approximately C-shaped. Two sliders 25 (one is omitted in FIG. 2) are fixed to the upper frame 23. The two sliders 25 are arranged at both ends of the upper frame 23 in the longitudinal direction. The two sliders 25 are slidably engaged with the two guide rails 170, respectively. Thereby, the car 120 is guided by the two guide rails 170 and moves in the vertical direction within the hoistway 110 (see FIG. 1).

As shown in FIG. 3, the vertical frames 22A and 22B have a base piece 221 and side pieces 222 and 223 continuous to the base piece 221. The base piece 221 is formed in a rectangular shape that is long in the vertical direction. The plane of the base piece 221 is perpendicular to the left-right direction. One plane of the base piece 221 faces the side plate 126C (126D) of the car room 121. Two connecting member through holes 221a are provided in the upper part of the base piece 221. A connecting member screw (bolt) 55 passes through each of the two connecting member through holes 221a (see FIG. 9).

The side pieces 222 and 223 stand up substantially perpendicularly from the long sides of the base piece 221. The side pieces 222, 223 are formed into rectangles that are long in the vertical direction. The planes of the side pieces 222, 223 are perpendicular to the front-rear direction. The side pieces 222, 223 face each other in the front-rear direction. Two through-holes 224 for raising members are provided in the upper portions of the side pieces 222 and 223, respectively. Vertical frame screws (bolts) 51 pass through the two raising member through holes 224 (see FIG. 6).

The upper frame 23 has a base piece 231 and side pieces 232 and 233 that are continuous with the base piece 231. The base piece 231 is formed into a rectangular shape that is long in the left-right direction. The plane of the base piece 231 is perpendicular to the vertical direction. One plane (lower surface) of the base piece 231 faces the ceiling plate 127 of the car compartment 121. Two connecting member through holes 231a are provided at both ends of the base piece 231 in the left and right direction. Connection member screws (bolts) 55 pass through the two connection member through holes 231a (see FIG. 9).

The side pieces 232 and 233 stand up substantially perpendicularly from the long sides of the base piece 231. The side pieces 232, 233 are formed into rectangles that are long in the left-right direction. The planes of the side pieces 232, 233 are perpendicular to the front-rear direction. The side pieces 232 and 233 face each other in the front-rear direction. Two raising member through holes 234 are provided at both ends of the side pieces 232 and 233 in the left and right direction, respectively. Upper frame screws (bolts) 53 pass through the two raising member through holes 234 (see FIG. 6).

[Elevating member]
Next, the structure of the raising member 31 will be explained with reference to FIGS. 4 and 5.
FIG. 4 is a perspective view of the raising member 31 viewed from the outside. FIG. 5 is a perspective view of the raising member 31 viewed from the inner side.

As shown in FIGS. 4 and 5, the raising member 31 is made of a plate having a substantially L-shaped planar shape. The raising member 31 has a vertical frame connecting portion 32 connected to the vertical frame 22A (22B) and an upper frame connecting portion 33 connected to the upper frame 23. The vertical frame connecting portion 32 is formed in a rectangular shape extending in the vertical direction. The vertical frame connecting portion 32 is provided with a vertical frame screw through hole 32a through which the vertical frame screw 51 passes. The vertical frame screw through hole 32a is formed in a vertically elongated shape extending in the vertical direction. Thereby, the vertical connection position of the raising member 31 can be easily changed.

The upper frame connecting portion 33 is continuous with the upper side of the vertical frame connecting portion 32. The upper frame connecting portion 33 has a rectangular screw-through piece 34 extending in the left-right direction and a support piece 35 continuous with the screw-through piece. The screw penetrating piece 34 contacts the side piece 232 (233) of the upper frame 23. The screw through piece 34 is provided with two upper frame screw through holes 34a and a hanging hole 34b.

The two upper frame screw through holes 34a are arranged at appropriate intervals in the left-right direction. The upper frame screws 53 pass through the two upper frame screw through holes 34a. The hanging hole 34b is arranged at the corner of the upper part of the screw penetrating piece 34 on the vertical frame connection part 32 side. This hanging hole 34b is used when suspending the raising member 31.

The support piece 35 is formed by bending. The support piece 35 protrudes substantially perpendicularly from the lower side of the screw penetrating piece 34. The support piece 35 comes into contact with one plane (lower surface) of the base piece 231 of the upper frame 23 . Thereby, the support piece 35 supports the lower part of the upper frame 23. As a result, the load of the upper frame 23 can be prevented from being concentrated on the upper frame screws 53.

[Elevating the upper frame]
Next, the work of raising the upper frame 23 will be explained with reference to FIGS. 6 to 9.
FIG. 6 is a perspective view showing a state in which the raising member 31 is connected to the car frame 122. FIG. 7 is a perspective view showing a state before the upper frame 23 is raised. FIG. 8 is a perspective view showing a state in which the upper frame 23 is raised. FIG. 9 is a perspective view showing a state in which the upper frame 23 and the vertical frame 22A are connected by a connecting member 37.

When installing the car 120 of the elevator 1 in a building structure, first, the vertical frames 22A and 22B of the car frame 122 are positioned with respect to the guide rail 170. Next, the upper frame 23 and the lower frame 21 are connected to the vertical frames 22A and 22B. When connecting the upper frame 23 to the vertical frame 22A (22B), four raising members 31 are used.

As shown in FIG. 6, in the connection work of the upper frame 23 and the vertical frame 22A (22B), the vertical frame screw through hole 32a of the raising member 31 and the two raising member through holes of the vertical frame 22A (22B) are connected. Two vertical frame screws (bolts) 51 are passed through the holes 224, and the nuts 52 are screwed together. Thereby, the raising member 31 and the vertical frame 22A (22B) are connected. At this time, the vertical frame screw 51 located above contacts the upper end of the vertical frame screw through hole 32a. The vertical frame screw 51 located below is located in the middle of the vertical frame screw through hole 32a.

Further, two upper frame screws (bolts) 53 are passed through the two raising member through holes 234 of the upper frame 23 and the two upper frame screw through holes 34a of the raising member 31, and the nuts 54 are screwed together. . Thereby, the raising member 31 and the upper frame 23 are connected. The upper frame 23 is positioned at a connection position with respect to the vertical frames 22A and 22B.

When the upper frame 23 and the vertical frame 22A (22B) are connected using the raising member 31, the steady rest member 41 provided on the side surface of the ceiling plate 127 is connected to the vertical frame 22A (22B) via the vibration isolating rubber 42. It contacts the frame connection part 32. Thereby, vibration of the car room 121 can be suppressed. The length of the vertical frame connecting portion 32 in the vertical direction is set to at least the length facing the steady rest member 41 (vibration isolating rubber 42).

Next, as shown in FIG. 7, the slider 25 is fixed to the upper frame 23, and the slider 25 is slidably engaged with the guide rail 170. At this time, connecting member screws (bolts) 55 are used as screws for fixing the slider 25. That is, the two connecting member screws (bolts) 55 are passed through the through holes of the slider 25, the connecting member 37, and the two connecting member through holes 231a of the upper frame 23, and the nuts 56 are screwed together.

After the slider 25 is fixed to the upper frame 23, the ceiling plate 127 of the car room 121 is placed within the car frame 122 and suspended. Next, the lower frame 21 and the side plates 126C and 126D are placed inside the car frame 122, and the four side plates 126A to 126D and the car floor 125 are connected. At this time, the car floor 125 is supported by the lower frame 21 of the car frame 122.

When connecting (assembling) the four side plates 126A to 126D, there is a risk that the side plates 126A to 126D and the ceiling plate 127 will interfere and damage the design of the ceiling plate 127. Therefore, the suspended ceiling plate 127 is raised to a position where it does not interfere with the side plates 126A to 126D. At this time, since the upper frame 23 of the car frame 122 interferes with the ceiling plate 127, work to raise the upper frame 23 is performed.

In the raising work, when the ceiling plate 127 is raised, the upper frame 23 is raised to a raised position where it does not interfere with the ceiling plate 127. In the raising work, first, the two vertical frame screws (bolts) 51 and nuts 52 are loosened. Thereby, the raising member 31 and the upper frame 23 connected to the raising member 31 become movable upward.

Thereafter, as shown in FIG. 8, the raising member 31 and the upper frame 23 are raised until the vertical frame screw 51 located below contacts the lower end of the vertical frame screw through hole 32a. Thereby, the upper frame 23 is placed in the raised position. Next, the vertical frame connecting portion 32 of the raising member 31 and the vertical frame 22A (22B) are fastened using two vertical frame screws (bolts) 51 and nuts 52. Thereby, the work of raising the upper frame 23 is completed.

After assembling the four side plates 126A to 126D within the car frame 122, the four side plates 126A to 126D and the ceiling plate 127 are connected. At this time, the ceiling plate 127 is lowered. Next, the two vertical frame screws (bolts) 51 and nuts 52 are loosened. Then, the raising member 31 and the upper frame 23 are lowered until the vertical frame screw 51 located above contacts the upper end of the vertical frame screw through hole 32a. Thereby, the upper frame 23 is placed at the connection position.

Next, the vertical frame connecting portion 32 of the raising member 31 and the vertical frame 22A (22B) are fastened using two vertical frame screws (bolts) 51 and nuts 52. Thereby, the upper frame 23 is fixed at the connection position.

Next, as shown in FIG. 9, the upper frame 23 and the vertical frame 22A are connected using the connecting member 37. This connecting member 37 increases the connection strength between the upper frame 23 and the vertical frame 22A. If the connection strength provided by the raising member 31 is sufficient, the connecting member 37 may be omitted. The connecting member 37 has a substantially L-shaped side surface.

As described above, the connecting member 37 is already fixed to the upper frame 23. Therefore, the connecting member 37 is fixed to the vertical frame 22A (22B). That is, the two connection member screws (bolts) 55 are passed through the two connection member through holes 221a of the connection member 37 and the vertical frame 22A (22B), and nuts (not shown) are screwed together. Thereby, the connecting member 37 is fixed to the vertical frame 22A (22B).

In this way, the car 120 according to the present embodiment includes the raising member 31 that is connected to the vertical frames 22A, 22B and the upper frame 23 using the vertical frame screws 51 and the upper frame screws 53. The raising member 31 has a vertical frame screw through hole 32a through which the vertical frame screw 51 passes, and an upper frame screw through hole 34a through which the upper frame screw 53 passes. The vertical frame screw through hole 32a is formed in a vertically elongated shape extending in the vertical direction. Thereby, by loosening the fastening of the vertical frame screws 51, the raising member 31 connected to the upper frame 23 can be easily moved upward. As a result, the work of raising the upper frame 23 can be facilitated. Furthermore, the raising member 31 can hold the upper frame 23 in the raised position. This results in

Further, the raising member 31 is connected to a vertical frame connecting portion 32 that is connected to the vertical frame 22A (22B) using vertical frame screws 51, and to the upper frame 23 using upper frame screws 53. It has an upper frame connection part 33. The upper frame connecting portion 33 includes a screw penetrating piece 34 in which an upper frame screw through hole 34 a is formed, and a support piece 35 that is continuous with the screw penetrating piece 34 and supports the lower part of the upper frame 23 . Thereby, the load of the upper frame 23 can be prevented from being concentrated on the upper frame screws 53.

Further, the screw penetrating piece 34 of the upper frame connecting portion 33 comes into contact with the upper frame 23 in the front-rear direction of the car compartment 121. Note that the front-rear direction of the cage 121 is a direction perpendicular to the vertical direction in which the vertical frames 22A, 22B extend and the left-right direction in which the upper frame 23 extends. Therefore, by connecting the upper frame 23 and the vertical frames 22A, 22B using the raising member 31, the upper frame 23 can be positioned with respect to the vertical frames 22A, 22B in the front-rear direction.

Further, in the raising member 31, the vertical frame screw through holes 32a and the upper frame screw through holes 34a have the same penetrating direction. Thereby, the worker can perform the work of threading the vertical frame screws 51 and the nuts 52 together and the work of threading the upper frame screws 53 and the nuts 54 without changing their posture. As a result, workability when connecting the raising member 31 to the vertical frames 22A, 22B and the upper frame 23 is improved.

Furthermore, a vibration-proofing rubber 42 (vibration-proofing material) is interposed between the raised member 31 and the steady rest member 41 of the car room 121. Thereby, vibration of the car room 121 can be suppressed. Further, the raising member 31 is connected to the vertical frames 22A, 22B and the upper frame 23 even after the elevator 1 is installed. Therefore, parts that become unnecessary after the elevator 1 is installed can be reduced.

Furthermore, the raising member 31 has a hanging hole 34b. Thereby, the raising member 31 can be easily carried to an arbitrary height. Further, when connected to the upper frame 23 and the vertical frames 22A and 22B, the entire car frame 122 can be suspended. As a result, the position of the car frame 122 can be easily adjusted.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention as set forth in the claims.

In the embodiment described above, two vertical frame screws 51 are used to connect the raising member 31 and the vertical frames 22A, 22B. However, at least one vertical frame screw 51 may be used to connect the raising member according to the present invention to the vertical frame. Further, in the embodiment described above, two upper frame screws 53 are used to connect the raising member 31 and the upper frame 23. However, at least one upper frame screw 53 may be used to connect the raising member according to the present invention to the upper frame.

In addition, although words such as "parallel" and "orthogonal" are used in this specification, these do not mean strictly "parallel" and "orthogonal", but include "parallel" and "orthogonal". , and may also be in a "substantially parallel" or "substantially perpendicular" state within the range where the function can be achieved.
