The upper parts of the side pieces 222 and 223 are respectively provided with two through-holes 224 for heightening members. The screws (bolts) 51 for the vertical frame pass through the two through-holes 224 for heightening members (see FIG. 6 ).

The upper frame 23 has a base sheet 231 and side sheets 232 and 233 continuous with the base sheet 231 . The substrate 231 is formed in a long rectangle in the left-right direction. The plane of the substrate 231 is perpendicular to the up-down direction. One plane (lower surface) of the base sheet 231 is opposed to the roof panel 127 of the car 121 . Two through-holes 231 a for connection members are provided at both ends in the left-right direction of the base sheet 231 . The connecting member screws (bolts) 55 pass through the two connecting member through-holes 231 a (see FIG. 9 ).

The side panels 232 , 233 stand approximately vertically from the long sides of the base sheet 231 . The side panels 232 and 233 are formed in long rectangles in the left-right direction. The planes of the side panels 232 and 233 are perpendicular to the front-back direction. The side panels 232, 233 face each other in the front-rear direction. Two through-holes 234 for heightening members are respectively provided at both ends in the left-right direction of the side pieces 232 and 233 . The screws (bolts) 53 for the upper frame pass through the two through-holes 234 for heightening members (see FIG. 6 ).

[heightening member]

Next, the configuration of the heightening member 31 will be described with reference to FIGS. 4 and 5 .

FIG. 4 is a perspective view of the heightening member 31 viewed from the outer side. FIG. 5 is a perspective view of the heightening member 31 viewed from the inner surface side.

As shown in FIGS. 4 and 5 , the heightening member 31 is composed of a plate body having a substantially L-shaped planar shape. The heightening member 31 has the vertical frame connection part 32 connected to the vertical frame 22A (22B), and the upper frame connection part 33 connected to the upper frame 23. As shown in FIG. The vertical frame connecting portion 32 is formed in a rectangle extending in the vertical direction. The vertical frame connection part 32 is provided with the screw penetration hole 32a for vertical frames through which the screw 51 for vertical frames penetrates. The vertical frame screw through hole 32a is formed in a vertically long shape extending in the vertical direction. Thereby, the connection position of the taller member 31 in the up-down direction can be changed easily.

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 penetration piece 34 extending in the left-right direction and a support piece 35 continuous with the screw penetration piece. The screw penetration piece 34 is in contact with the side piece 232 ( 233 ) of the upper frame 23 . The screw penetration piece 34 is provided with two upper frame screw penetration holes 34a and a suspension hole 34b.

The two upper frame screw through holes 34 a 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 hole 34b for suspension is arranged at the upper corner of the screw penetration piece 34 on the side of the vertical frame connecting portion 32 . The hole 34b for suspension is used when the heightening member 31 is suspended.

The support piece 35 is formed by bending. The support piece 35 protrudes approximately vertically from the lower side of the screw penetration piece 34 . The supporting piece 35 is in contact with one flat surface (lower surface) of the substrate 231 of the upper frame 23 . Thus, the support piece 35 supports the lower portion 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 .

[Heightening operation of the upper frame]

Next, the heightening operation of the upper frame 23 will be described with reference to FIGS. 6 to 9 .

FIG. 6 is a perspective view showing a state where the heightening 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 where the upper frame 23 is raised. FIG. 9 is a perspective view showing a state where the upper frame 23 and the vertical frame 22A are connected by the connecting member 37 .

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

As shown in FIG. 6, in the connection operation between the upper frame 23 and the vertical frame 22A (22B), two vertical frame screws (bolts) 51 are inserted through the vertical frame screw through holes 32a of the heightening member 31 and the vertical frame 22A. The two heightening members of (22B) pass through the holes 224 and screw the nuts 52 together. Thereby, the heightening member 31 is connected to the vertical frame 22A (22B). At this time, the upper end of 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 part of the vertical frame screw through-hole 32a.

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

When the upper frame 23 and the vertical frame 22A ( 22B) are connected using the heightening member 31 , the anti-vibration member 41 provided on the side of the car roof 127 contacts the vertical frame connecting portion 32 of the heightening member 31 via the anti-vibration rubber 42 . Accordingly, vibration of the car 121 can be suppressed. The vertical length of the vertical frame connecting portion 32 is set to be at least a length facing the vibration-proof member 41 (vibration-proof rubber 42 ).

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

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

When the four side panels 126A to 126D are connected (assembled), the side panels 126A to 126D and the car roof 127 may interfere with the appearance of the car roof 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 car roof 127, the work of raising the height of the upper frame 23 is performed.

In the raising operation, when raising the car roof 127 , the upper frame 23 is raised to a raised position where it does not interfere with the car roof 127 . In the heightening work, first, loosen the fastening of the two vertical frame screws (bolts) 51 and nuts 52 . Thereby, the heightening member 31 and the upper frame 23 connected to the heightening member 31 can move upward.

Thereafter, as shown in FIG. 8 , the heightening member 31 and the upper frame 23 are raised until the vertical frame screws 51 located below come into contact with the lower ends of the vertical frame screw through holes 32 a. Thereby, the upper frame 23 is arrange|positioned at a raised position. Next, the vertical frame connecting portion 32 of the heightening member 31 and the vertical frame 22A ( 22B) are fastened with two vertical frame screws (bolts) 51 and nuts 52 . Thus, the heightening operation of the upper frame 23 is completed.

In the car frame 122 , after the four side panels 126A to 126D are assembled, the four side panels 126A to 126D are connected to the car roof panel 127 . At this time, the car roof 127 is lowered. Next, the two vertical frame screws (bolts) 51 and nuts 52 are loosened. Then, the heightening member 31 and the upper frame 23 are lowered until the upper end of 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 arranged at the connection position.

Next, the vertical frame connecting portion 32 of the heightening member 31 and the vertical frame 22A ( 22B) are fastened with 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 connection member 37 . The connection member 37 increases the connection strength between the upper frame 23 and the vertical frame 22A. In the case where the connection strength of the heightening member 31 is sufficient, the connection member 37 may be omitted. The side shape of the connecting member 37 is formed in a substantially L-shape.

As described above, the connection member 37 has been fixed to the upper frame 23 . Therefore, the connecting member 37 is fixed to the vertical frame 22A ( 22B). That is, two connecting member screws (nuts) 55 are passed through the connecting member 37 and the two connecting member through-holes 221a of 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).

Thus, the car 120 according to the present embodiment includes the heightening member 31 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 heightening member 31 has the vertical frame screw penetration hole 32a through which the vertical frame screw 51 penetrates, and the upper frame screw penetration hole 34a through which the upper frame screw 53 penetrates. And the vertical frame screw penetration hole 32a is formed in the vertically long shape extended in the up-down direction. Thereby, the heightening member 31 connected to the upper frame 23 can be easily moved upward by loosening the fastening of the vertical frame screws 51 . As a result, the work of raising the height of the upper frame 23 can be facilitated. In addition, the raising member 31 can hold the upper frame 23 in a raised position. thus,

Moreover, the heightening member 31 has the vertical frame connection part 32 connected to the vertical frame 22A (22B) with the vertical frame screw 51, and the upper frame connection part 33 connected to the upper frame 23 with the upper frame screw 53. Then, the upper frame connecting portion 33 has a penetration piece 34 formed with an upper frame screw penetration hole 34a, and a support piece 35 which is continuous with the screw penetration piece 34 and supports the lower portion 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 .

In addition, the screw penetration piece 34 of the upper frame connection portion 33 is in contact with the upper frame 23 in the front-rear direction of the car compartment 121 . In addition, the front-rear direction of the car chamber 121 is a direction orthogonal to the up-down direction in which the vertical frames 22A and 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 heightening member 31, the positioning of the front-back direction of the upper frame 23 with respect to the vertical frames 22A, 22B can be performed.

Moreover, in the heightening member 31, the penetration direction of the screw penetration hole 32a for vertical frames and the screw penetration hole 34a for upper frame is the same. Accordingly, the operator can perform the work of screwing the vertical frame screws 51 and the nuts 52 and the work of screwing the upper frame screws 53 and the nuts 54 without changing the posture. As a result, workability when the heightening member 31 is connected to the vertical frames 22A, 22B and the upper frame 23 is improved.

In addition, vibration-proof rubber 42 (vibration-proof material) is interposed between the heightening member 31 and the vibration-proof member 41 of the car compartment 121 . Accordingly, vibration of the car 121 can be suppressed. In addition, the heightening member 31 can also be connected to the vertical frames 22A, 22B and the upper frame 23 after the installation of the elevator 1 . Therefore, unnecessary components after the elevator 1 is installed can be reduced.

Moreover, the heightening member 31 has the hole 34b for suspension. Thereby, the raising member 31 can be easily transported to an arbitrary height. Moreover, when being connected to the upper frame 23 and the vertical frames 22A and 22B, the whole car frame 122 can be suspended. As a result, the position adjustment of the car frame 122 can be easily performed.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made within a range not departing from the gist of the invention described in the claims.

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

In addition, in this specification, words such as "parallel" and "orthogonal" are used, but they do not only mean strict "parallel" and "orthogonal", but may include parallel" and "orthogonal", and are in The state of "approximately parallel" and "approximately orthogonal" within the range where the function can be exerted.
