[0030] In each of the first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43, in a state where the stepped portion 23 is hung on the guide portion 16, the inner surface of the stepped portion 23 contacts one rail side surface 161 and the rail end surface 162 in the guide portion 16.

[0031] Each of the first rail mounting portion 32 and the second rail mounting portion 33 is provided with an alignment portion 34. The first main gauge 3 is arranged by aligning each alignment portion 34 with the positions of a pair of piano wires stretched in the hoistway 1. The first main gauge 3 is attached to the first guide rail 11 and the second guide rail 12 and arranged at positions based on the pair of piano wires, thereby centering each of the first guide rail 11 and the second guide rail 12.

[0032] The second main gauge 4 is attached to the third guide rail 13 and the fourth guide rail 14 and positioned with respect to the first main gauge 3, thereby centering each of the third guide rail 13 and the fourth guide rail 14.

[0033] The connector 5 has a first sub-gauge 51, a second sub-gauge 52, and a third sub-gauge 53 as a plurality of sub-gauges 51 to 53. The plurality of sub-gauges 51 to 53 connect the third rail mounting portion 42 and the fourth rail mounting portion 43 to the first rail mounting portion 32 and the second rail mounting portion 33. The connector 5 positions the second main gauge 4 with respect to the first main gauge 3 by connecting the third rail mounting portion 42 and the fourth rail mounting portion 43 to the first rail mounting portion 32 and the second rail mounting portion 33.

[0034] Each of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53 connects either the third rail mounting portion 42 or the fourth rail mounting portion 43 to either the first rail mounting portion 32 or the second rail mounting portion 33. Specifically, the first sub-gauge 51 connects the third rail mounting portion 42 to the first rail mounting portion 32. The second sub-gauge 52 connects the third rail mounting portion 42 to the second rail mounting portion 33. The third sub-gauge 53 connects the fourth rail mounting portion 43 to the second rail mounting portion 33.

[0035] The four gauge mountings 6 are individually attached to a first rail mounting portion 32, a second rail mounting portion 33, a third rail mounting portion 42, and a fourth rail mounting portion 43. The first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43 are mounting target portions corresponding individually to the four gauge mountings 6. Each gauge mounting 6 is attached to the corresponding mounting target portion.

[0036] Any one of a first sub-gauge 51, a second sub-gauge 52, and a third sub-gauge 53 is connected to each gauge mounting 6. As a result, any one of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53 is attached to each of the first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43 via the gauge mounting 6.

[0037] Specifically, one end of the first sub-gauge 51 is connected to the gauge mounting 6 attached to the first rail mounting portion 32. One end of each of the second sub-gauge 52 and the third sub-gauge 53 is connected to the gauge mounting 6 attached to the second rail mounting portion 33. The other ends of each of the first sub-gauge 51 and the second sub-gauge 52 are connected to the gauge mounting 6 attached to the third rail mounting portion 42. The other end of the third sub-gauge 53 is connected to the gauge mounting 6 attached to the fourth rail mounting portion 43.

[0038] Each gauge mounting 6 is detachably attached to the corresponding mounting target portion among the first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43 by a plurality of fixtures 61. Also, each gauge mounting 6 designates the guide rail to which the corresponding mounting target portion is attached as a reference guide rail among the first guide rail, the second guide rail, the third guide rail, and the fourth guide rail.

[0039] Therefore, the reference guide rail of the gauge attachment 6 attached to the first rail attachment portion 32 is the first guide rail 11. The reference guide rail of the gauge attachment 6 attached to the second rail attachment portion 33 is the second guide rail 12. The reference guide rail of the gauge attachment 6 attached to the third rail attachment portion 42 is the third guide rail 13. The reference guide rail of the gauge attachment 6 attached to the fourth rail attachment portion 43 is the fourth guide rail 14.

[0040] The configurations of the respective gauge attachments 6 are all the same. Here, the configuration of the gauge attachment 6 attached to the first rail attachment portion 32, that is, the configuration of the gauge attachment 6 with the first rail attachment portion 32 as the attachment target portion and the first guide rail 11 as the reference guide rail will be described.

[0041] FIG. 3 is a perspective view showing the gauge attachment 6 attached to the first rail attachment portion 32 of FIG. 1. The gauge attachment 6 has an attachment 7 and a connector 8.

[0042] The attachment 7 is detachably attached to the first rail attachment portion 32, which is the corresponding attachment target portion, by a plurality of fixtures 61. In the present embodiment, the attachment 7 is attached to the first rail attachment portion 32 by two fixtures 61. Also, in the present embodiment, fastening bolts are used as the fixtures 61.

[0043] The attachment 7 is attached to the first rail attachment portion 32 in a state of overlapping the gripping main body portion 21 of the first rail attachment portion 32. A plurality of fixture retaining holes (not shown) for retaining each fixture 61 are provided in the gripping main body portion 21 of the first rail attachment portion 32. In the present embodiment, a plurality of screw holes into which each fixture 61 is screwed are provided in the gripping main body portion 21 as the fixture retaining holes.

[0044] The connector 8 is detachably attached to the attachment 7. The connector 8 is connectable to all of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53. In the present embodiment, a pin is used as the connector 8.

[0045] One of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53 is connected to the connector 8. In the gauge attachment 6 with the first rail attachment portion 32 as the attachment target portion, the first sub-gauge 51 is connected to the connector 8.

[0046] The attachment 7 is a plate formed with a first surface 71 and a second surface 72 facing opposite sides. In the attachment 7, a specific direction along the first surface 71 is defined as the front-rear direction, and a direction perpendicular to the front-rear direction along the first surface 71 is defined as the left-right direction.

[0047] The attachment 7 has a front end portion 7a, a rear end portion 7b, a first side portion 7c, and a second side portion 7d. Of the both end portions in the front-rear direction of the attachment 7, one end portion is the front end portion 7a and the other end portion is the rear end portion 7b. Also, of the both end portions in the left-right direction of the attachment 7, one end portion is the first side portion 7c and the other end portion is the second side portion 7d.

[0048] Here, FIG. 4 is a perspective view showing the attachment 7 of FIG. 3. The attachment 7 is provided with a plurality of first fixture through holes 73a and a plurality of second fixture through holes 73b. In the present embodiment, two first fixture through holes 73a and two second fixture through holes 73b are provided in the attachment 7. The first fixture through holes 73a and the second fixture through holes 73b are located at positions separated from each other in the left-right direction of the attachment 7. The two first fixture through holes 73a are located at positions separated from each other in the front-rear direction of the attachment 7. The two second fixture through holes 73b are also located at positions separated from each other in the front-rear direction of the attachment 7.

[0049] The gauge attachment 6 with the first rail attachment portion 32 as the attachment target portion uses the first guide rail 11 as the reference guide rail. The attachment 7 can be attached to the first rail attachment portion 32 with the front end portion 7a facing the first guide rail 11 which is the reference guide rail, with the orientations of the first surface 71 and the second surface 72 reversed respectively. Thus, the attachment state of the attachment 7 to the first rail attachment portion 32 can be changed between a first attachment state and a second attachment state.

[0050] When the attachment state of the attachment 7 is the first attachment state, the attachment 7 faces the front end portion 7a towards the reference guide rail, overlaps one of the first surface 71 and the second surface 72 with the attachment target portion, and is attached to the attachment target portion by the fixture 61 passed through the first fixture through hole 73a. When the attachment state of the attachment 7 is the second attachment state, the attachment 7 faces the front end portion 7a towards the reference guide rail, overlaps the other of the first surface 71 and the second surface 72 with the attachment target portion, and is attached to the attachment target portion by the fixture 61 passed through the second fixture through hole 73b.

[0051] In the gauge attachment 6 with the first rail attachment portion 32 as the attachment target portion, the second surface 72 is overlapped with the first rail attachment portion 32 in the first attachment state, and the first surface 71 is overlapped with the first rail attachment portion 32 in the second attachment state. FIG. 3 shows the attachment 7 when it is in the first attachment state. In either the first attachment state or the second attachment state of the attachment 7, the left - right direction of the attachment 7 coincides with the width direction of the guide portion 16 in the first guide rail 11.

[0052] The positions of the first side portion 7c and the second side portion 7d with respect to the first rail attachment portion 32 are interchanged when the attachment state of the attachment 7 is the first attachment state and when the attachment state of the attachment 7 is the second attachment state. In either the first attachment state or the second attachment state of the attachment 7, each fixture 61 is screwed into the same screw hole in the first rail attachment portion 32.

[0053] The attachment 7 is provided with a first interference avoidance hole 74a and a second interference avoidance hole 74b. When the attachment state of the attachment 7 is the first attachment state, the first interference avoidance hole 74a avoids interference between the fastening shaft 24 in the first rail attachment portion 32 and the attachment 7. In the first attachment state, as shown in FIG. 3, the fastening shaft 24 is located inside the first interference avoidance hole 74a.

[0054] When the attachment state of the attachment 7 is the second attachment state, the second interference avoidance hole 74b avoids interference between the fastening shaft 24 in the first rail attachment portion 32 and the attachment 7. In the second attachment state, the fastening shaft 24 is located inside the second interference avoidance hole 74b.

[0055] The attachment 7 is provided with a plurality of first connector attachment holes 75a and a plurality of second connector attachment holes 75b as a plurality of connector attachment holes 75. The connector 8 can be selectively attached to the plurality of connector attachment holes 75.

[0056] When the attachment state of the attachment 7 is the first attachment state, the connector 8 can be selectively attached to the plurality of first connector attachment holes 75a. The position of each first connector attachment hole 75a is determined based on the position of the plurality of first fixture through holes 73a. In the present embodiment, two first connector attachment holes 75a are provided on the first side portion 7c of the attachment 7. Also, in the present embodiment, the two first connector attachment holes 75a are provided on the attachment 7 with a space therebetween in the front-rear direction of the attachment 7.

[0057] When the attachment state of the attachment 7 is the second attachment state, the connector 8 can be selectively attached to the plurality of second connector attachment holes 75b. The position of each second connector attachment hole 75b is determined based on the position of the plurality of second fixture through holes 73b. In the present embodiment, two second connector attachment holes 75b are provided on the second side portion 7d of the attachment 7. Also, in the present embodiment, the two second connector attachment holes 75b are provided on the attachment 7 with a space therebetween in the front-rear direction of the attachment 7.

[0058] The attachment 7 is provided with a first notch 76a and a second notch 76b. The first notch 76a is provided at the front end 7a of the attachment 7 and on the first side portion 7c of the attachment 7. The second notch 76b is provided at the front end 7a of the attachment 7 and on the second side portion 7d of the attachment 7.

[0059] An attachment display 77 is attached to each of the first surface 71 and the second surface 72. The attachment display 77 is a display for assisting in specifying the connector mounting holes 75 to be selected according to the difference in the layout of the plurality of guide rails 11 to 14, that is, the difference in the positional relationship of the plurality of guide rails 11 to 14.

[0060] Here, consider the case where the size of the first guide rail 11 is the first size and the case where the size of the first guide rail 11 is a second size different from the first size.

[0061] FIG. 5 is a top view showing the mounting state of the attachment 7 when the size of the first guide rail 11 in FIG. 1 is the first size. FIG. 6 is a top view showing the mounting state of the attachment 7 when the size of the first guide rail 11 in FIG. 1 is the second size.

[0062] Comparing the first guide rail 11 of the first size with the first guide rail 11 of the second size, the width dimension of the guide portion 16 is different between the first size and the second size. In the present embodiment, the first size is larger than the second size. Specifically, the width dimension t1 of the guide portion 16 in the first guide rail 11 of the first size is larger than the width dimension t2 of the guide portion 16 in the first guide rail 11 of the second size.

[0063] For each of the plurality of guide rails 11 to 14, the center line of the guide portion 16 when viewing the hoistway 1 from above is set as the rail reference. The centering of the first guide rail 11 is performed by aligning the rail reference of the first guide rail 11, that is, the center line of the first guide rail 11, with the first guide rail reference line A shown in FIG. 2.

[0064] On the other hand, the first rail mounting portion 32 is attached to the first guide rail 11 by hanging the step portion 23 on the guide portion 16 of the first guide rail 11. The positions of the pair of rail side surfaces 161 formed on the guide portion 16 change with respect to the center line of the first guide rail 11 when the size of the first guide rail 11 changes. Therefore, the position of the first rail mounting portion 32 with respect to the center line of the first guide rail 11 is different depending on whether the size of the first guide rail 11 is the first size and whether the size of the first guide rail 11 is the second size, corresponding to the difference between the first size and the second size.

[0065] Specifically, the position of the first rail mounting portion 32 moves away from the center line of the first guide rail 11 in the width direction of the guide portion 16 as the width dimension of the guide portion 16 in the first guide rail 11 increases. Therefore, in the present embodiment, the position of the first rail mounting portion 32 is farther from the center line of the first guide rail 11 in the width direction of the guide portion 16 when the size of the first guide rail 11 is the first size than when the size of the first guide rail 11 is the second size.

[0066] When the size of the first guide rail 11 is the first size, as shown in FIG. 5, the attachment state of the attachment 7 is set to the first attachment state. At this time, the position of each first connector mounting hole 75a with respect to the center line of the first guide rail 11 is defined as the first state mounting hole position.

[0067] When the size of the first guide rail 11 is the second size, as shown in FIG. 6, the attachment state of the attachment 7 is set to the forward second attachment state. At this time, the position of each second connector mounting hole 75b with respect to the center line of the first guide rail 11 is defined as the second state mounting hole position.

[0068] As described above, the positions of the first rail attachment portions 32 with respect to the center line of the first guide rail 11 are different from each other according to the difference between the first size and the second size. In the attachment 7, the positions of the respective second connector attachment holes 75b with respect to the second attachment tool through hole 73b are different from the positions of the respective first connector attachment holes 75a with respect to the first attachment tool through hole 73a according to the difference between the second size and the first size. Thereby, the first state attachment hole position and the second state attachment hole position coincide with respect to the center line of the first guide rail 11.

[0069] That is, in the attachment 7, the positions of the respective first connector attachment holes 75a with respect to the first attachment tool through hole 73a and the positions of the respective first connector attachment holes 75a with respect to the first attachment tool through hole 73a are determined so that the first state attachment hole position and the second state attachment hole position coincide with respect to the center line of the first guide rail 11. In the present embodiment, the positions of the respective first connector attachment holes 75a with respect to the first attachment tool through hole 73a and the positions of the respective first connector attachment holes 75a with respect to the first attachment tool through hole 73a are determined so that the first state attachment hole position and the second state attachment hole position coincide at positions on the center line of the first guide rail 11.

[0070] The positions of the respective first connector attachment holes 75a with respect to the first attachment tool through hole 73a are determined according to the first size of the first guide rail 11. Specifically, a first attachment distance L1, which is the distance from the center of the first attachment tool through hole 73a to the center of each first connector attachment hole 75a in the left - right direction of the attachment 7, is determined according to the width dimension t1 of the guide portion 16 in the first guide rail 11.

[0071] The positions of the respective second connector attachment holes 75b with respect to the second attachment tool through hole 73b are determined according to the second size of the first guide rail 11. Specifically, a second attachment distance L2, which is the distance from the center of the second attachment tool through hole 73b to the center of each second connector attachment hole 75b in the left - right direction of the attachment 7, is determined according to the width dimension t2 of the guide portion 16 in the first guide rail 11.

[0072] Therefore, the first mounting distance L1 and the second mounting distance L2 are different from each other due to the difference between the width dimension t1 of the guide portion 16 corresponding to the first size and the width dimension t2 of the guide portion 16 corresponding to the second size. The difference between the first mounting distance L1 and the second mounting distance L2 is (t1 - t2) / 2.

[0073] The position of the first rail mounting portion 32 is closer to the center line of the first guide rail 11 by (t1 - t2) / 2 when the size of the first guide rail 11 is the second size than when the size of the first guide rail 11 is the first size.

[0074] On the other hand, in the attachment 7, the second mounting distance L2 is shorter than the first mounting distance L1 by the amount that the position of the first rail mounting portion 32 approaches the center line of the first guide rail 11 due to the difference between the first size and the second size. As a result, the first state mounting hole position and the second state mounting hole position coincide with respect to the center line of the first guide rail 11.

[0075] When the attachment state of the attachment 7 is the first attachment state, the attachment 7 is arranged with the position of the first notch portion 76a aligned with the step portion 23 of the first rail mounting portion 32. As a result, when the attachment state of the attachment 7 is the first attachment state, as shown in FIG. 5, the first notch portion 76a catches on the first guide rail 11. In a state where the first notch portion 76a catches on the first guide rail 11, the inner surface of the first notch portion 76a contacts one rail side surface 161 and the rail end surface 162 of the first guide rail 11.

[0076] When the attachment state of the attachment 7 is the second attachment state, the attachment 7 is arranged with the position of the second notch portion 76b aligned with the position of the step portion 23 of the first rail attachment portion 32. Thereby, when the attachment state of the attachment 7 is the second attachment state, as shown in FIG. 6, the second notch portion 76b catches on the first guide rail 11. In the state where the second notch portion 76b catches on the first guide rail 11, the inner surface of the second notch portion 76b contacts one rail side surface 161 and the rail end surface 162 of the first guide rail 11.

[0077] Here, let the distance from the center of the first fitting through hole 73a in the left - right direction of the attachment 7 to the first notch portion 76a be the first notch distance L11. Also, let the distance from the center of the second fitting through hole 73b in the left - right direction of the attachment 7 to the second notch portion 76b be the second notch distance L21. In this case, the first notch distance L11 and the second notch distance L21 are the same distance from each other.

[0078] Also, let the distance from the first notch portion 76a in the left - right direction of the attachment 7 to the center of each first connector attachment hole 75a be the first adjustment distance L12. Further, let the distance from the second notch portion 76b in the left - right direction of the attachment 7 to the center of each second connector attachment hole 75b be the second adjustment distance L22. In this case, the first adjustment distance L12 and the second adjustment distance L22 are different from each other according to the difference between the first size and the second size. In the present embodiment, the difference between the first adjustment distance L12 and the second adjustment distance L22 is (t1 - t2) / 2.

[0079] The first attachment distance L1 is the distance obtained by adding the first adjustment distance L12 to the first notch distance L11. The second attachment distance L2 is the distance obtained by adding the second adjustment distance L22 to the second notch distance L21.

[0080] The configuration of each gauge attachment 6 with the second rail attachment portion 33, the third rail attachment portion 42, and the fourth rail attachment portion 43 as the attachment target portions is the same as the configuration of the gauge attachment 6 with the first rail attachment portion 32 described above as the attachment target portion. The relationship between the reference guide rail and the attachment 7 in each gauge attachment 6 with the second rail attachment portion 33, the third rail attachment portion 42, and the fourth rail attachment portion 43 as the attachment target portions is also the same as that of the gauge attachment 6 with the first rail attachment portion 32 as the attachment target portion.

[0081] When comparing the two gauge attachments 6 with the first rail attachment portion 32 and the second rail attachment portion 33 as the attachment target portions, as shown in FIG. 2, the directions of the front end portions 7a of the attachment 7 are opposite to each other between one gauge attachment 6 and the other gauge attachment 6. Also, when comparing the two gauge attachments 6 with the third rail attachment portion 42 and the fourth rail attachment portion 43 as the attachment target portions, the directions of the front end portions 7a of the attachment 7 are opposite to each other between one gauge attachment 6 and the other gauge attachment 6.

[0082] Therefore, in the two gauge attachments 6 with the first rail attachment portion 32 and the third rail attachment portion 42 as the attachment target portions, the surface that overlaps the attachment target portion in the first attachment state is the second surface 72, and the surface that overlaps the attachment target portion in the second attachment state is the first surface 71. On the other hand, in the two gauge attachments 6 with the second rail attachment portion 33 and the fourth rail attachment portion 43 as the attachment target portions, the surface that overlaps the attachment target portion in the first attachment state is the first surface 71, and the surface that overlaps the attachment target portion in the second attachment state is the second surface 72.

[0083] The attachment display 77 in each gauge attachment 6 has a first surface display 77a for the first state, a first surface display 77b for the second state, a second surface display 77c for the first state, and a second surface display 77d for the second state.

[0084] As shown in FIG. 5, the first surface display 77a for the first state is provided around a plurality of first connector attachment holes 75a on the first surface 71. The first surface display 77b for the second state is provided around a plurality of second connector attachment holes 75b on the first surface 71. As shown in FIG. 6, the first surface display 77c for the first state is provided around a plurality of first connector attachment holes 75a on the second surface 72. The second surface display 77d for the second state is provided around a plurality of second connector attachment holes 75b on the second surface 72.

[0085] In the two gauge fixtures 6 with the first rail attachment portion 32 and the third rail attachment portion 42 as the attachment target portions, the first connector attachment hole 75a to be selected from among the plurality of first connector attachment holes 75a in the first attachment state is specified based on the content of the first surface display 77a for the first state. Also, in the two gauge fixtures 6 with the first rail attachment portion 32 and the third rail attachment portion 42 as the attachment target portions, the second connector attachment hole 75b to be selected from among the plurality of second connector attachment holes 75b in the second attachment state is specified based on the content of the second surface display 77d for the second state.

[0086] In the two gauge fixtures 6 with the second rail attachment portion 33 and the fourth rail attachment portion 43 as the attachment target portions, the first connector attachment hole 75a to be selected from among the plurality of first connector attachment holes 75a in the first attachment state is specified based on the content of the second surface display 77c for the first state. Also, in the two gauge fixtures 6 with the second rail attachment portion 33 and the fourth rail attachment portion 43 as the attachment target portions, the second connector attachment hole 75b to be selected from among the plurality of second connector attachment holes 75b in the second attachment state is specified based on the content of the second surface display 77b for the second state.

[0087] The distinction between the plurality of first connector attachment holes 75a and the distinction between the plurality of second connector attachment holes 75b are made, for example, by color-coding of the attachment display 77.

[0088] When the sizes of the respective guide rails 11 to 14 are the first size, in each gauge adapter 6, the attachment state of the attachment 7 to the corresponding attachment target portion is set to the first attachment state. In this case, in each gauge adapter 6, the connector 8 is attached to the first connector attachment hole 75a selected from among the plurality of first connector attachment holes 75a.

[0089] When the sizes of the respective guide rails 11 to 14 are the second size, in each gauge adapter 6, the attachment state of the attachment 7 to the corresponding attachment target portion is set to the second attachment state. In this case, in each gauge adapter 6, the connector 8 is attached to the second connector attachment hole 75b selected from among the plurality of second connector attachment holes 75b.

[0090] Thereby, regardless of whether the sizes of the respective guide rails 11 to 14 are the first size or the second size, in each gauge adapter 6, the position of the connector 8 with respect to the center line of the reference guide rail becomes the same position. Therefore, the positional relationship of the connectors 8 in the four gauge adapters 6 does not change regardless of whether the sizes of the respective guide rails 11 to 14 are the first size or the second size. Thereby, each of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53 can be used interchangeably when the sizes of the respective guide rails 11 to 14 are the first size and when the sizes of the respective guide rails 11 to 14 are the second size.

[0091] On the other hand, when the guide rail centering device 2 is used for two types of elevators in which the positional relationships of the plurality of guide rails 11 to 14 are different from each other, in each gauge adapter 6, the connector 8 is attached to the connector attachment hole 75 selected according to the difference in the positional relationships of the plurality of guide rails 11 to 14.

[0092] In each gauge attachment 6, the connector attachment hole 75 is selected from among a plurality of first connector attachment holes 75a when the attachment state of the attachment 7 is the first attachment state, and is selected from among a plurality of second connector attachment holes 75a when the attachment state of the attachment 7 is the second attachment state. The selection of the connector attachment hole 75 in each gauge attachment 6 is performed so that the distances between the respective connectors 8 are the same in two types of elevators. Thereby, each of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53 can be used in common in two types of elevators.

[0093] In such a guide rail centering device 2, each gauge attachment 6 has an attachment 7 and a connector 8. The attachment 7 is detachably attached to a corresponding attachment target portion. The connector 8 is detachably attached to the attachment 7. One of a plurality of sub-gauges 51 to 53 is connected to the connector 8. The attachment 7 is provided with a plurality of connector attachment holes 75 to which the connector 8 can be selectively attached. Therefore, by changing the connector attachment hole 75 to which the connector 8 is attached among the plurality of connector attachment holes 75, the position of the connector 8 with respect to the reference guide rail to which the attachment target portion is attached can be easily changed. Thereby, the connector 8 of each gauge attachment 6 can be arranged at a position where each of the plurality of sub-gauges 51 to 53 can be connected in any of two types of elevators in which the positional relationships of the plurality of guide rails 11 to 14 are different from each other. Therefore, each of the plurality of sub-gauges 51 to 53 can be used in common in two types of elevators in which the positional relationships of the plurality of guide rails 11 to 14 are different from each other. Thereby, it is not necessary to use different types of sub-gauges in each of the two types of elevators, and the number of types of sub-gauges can be reduced.

[0094] In addition, the attachment state of the attachment 7 to the attachment target portion can be changed between a first attachment state and a second attachment state. When the attachment state of the attachment 7 is the first attachment state, the attachment 7 faces the front end portion 7a toward the reference guide rail, overlaps one of the first surface 71 and the second surface 72 with the attachment target portion, and is attached to the attachment target portion by the fixture 61 passed through the first fixture through hole 73a. When the attachment state of the attachment 7 is the second attachment state, the attachment 7 faces the front end portion 7a toward the reference guide rail, overlaps the other of the first surface 71 and the second surface 72 with the attachment target portion, and is attached to the attachment target portion by the fixture 61 passed through the second fixture through hole 73b. The positions of the plurality of first connector attachment holes 75a with respect to the first fixture through hole 73a are determined according to the first size. The positions of the plurality of second connector attachment holes 75b with respect to the second fixture through hole 73b are determined according to the second size. Therefore, even if the position of the attachment target portion with respect to the center line of the first guide rail 11 differs from each other according to the difference between the first size and the second size, the position of the connector 8 can be made to coincide with respect to the center line of the reference guide rail. Thereby, regardless of whether the size of the reference guide rail is the first size or the second size, each of the sub gauges 51 to 53 can be used in common. As a result, it is not necessary to use different types of sub gauges depending on the difference in the size of the reference guide rail, and the number of types of sub gauges can be reduced.

[0095] In addition, the attachment 7 is provided with a first notch portion 76a and a second notch portion 76b. When the attachment state of the attachment 7 is the first attachment state, the first notch portion 76a hangs on the reference guide rail. When the attachment state of the attachment 7 is the second attachment state, the second notch portion 76b hangs on the reference guide rail. For this reason, the positioning of the attachment 7 with respect to the reference guide rail can be directly performed by bringing the attachment 7 into contact with the reference guide rail. Thereby, the positioning of the attachment 7 with respect to the reference guide rail can be performed more accurately.

[0096] In addition, in the gauge attachment 6, the attachment 7 is detachably attached to the attachment target portion. Therefore, the gauge attachment 6 can be attached to each of the existing first main gauge 3 and the existing second main gauge 4.

[0097] Note that in the above embodiment, the number of the first connector attachment holes 75a in the attachment 7 is two. However, the number of the first connector attachment holes 75a in the attachment 7 is not limited to two. The number of the first connector attachment holes 75a in the attachment 7 may be three or more. In this way, a plurality of sub - gauges can be made to be used in common in more types of elevators in which the positional relationships of the plurality of guide rails 11 to 14 are different from each other.

[0098] Also, in the above embodiment, the number of the second connector attachment holes 75b in the attachment 7 is two. However, the number of the second connector attachment holes 75b in the attachment 7 is not limited to two. The number of the second connector attachment holes 75b in the attachment 7 may be three or more. In this way, a plurality of sub - gauges can be made to be used in common in more types of elevators in which the positional relationships of the plurality of guide rails 11 to 14 are different from each other.

[0099] In addition, in the above embodiment, the first notch portion 76a that engages with the reference guide rail in the first attachment state is provided in the attachment 7. However, if the attachment 7 can be attached to a predetermined position of the attachment target portion, the first notch portion 76a may not be provided in the attachment 7.

[0100] Also, in the above embodiment, the second notch portion 76b that engages with the reference guide rail in the second attachment state is provided in the attachment 7. However, if the attachment 7 can be attached to a predetermined position of the attachment target portion, the second notch portion 76b may not be provided in the attachment 7.

[0101] Also, in the above-described embodiment, each of the first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43 is a mounting target portion of the gauge mounting device 6. However, among the first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43, there may be a rail mounting portion that is not a mounting target portion of the gauge mounting device 6. For example, the third rail mounting portion 42 and the fourth rail mounting portion 43 may not be mounting target portions of the gauge mounting device 6, and the gauge mounting device 6 may be attachable only to the first rail mounting portion 32 and the second rail mounting portion 33. In this case, the connector 8 is directly attached to the rail mounting portion to which the gauge mounting device 6 cannot be attached, and any one of the plurality of sub-gauges 51 to 53 is connected to the connector 8 directly attached to the rail mounting portion. Even in this way, the number of types of sub-gauges can be reduced. Therefore, at least any one of the first rail mounting portion 32, the second rail mounting portion 33, the third rail mounting portion 42, and the fourth rail mounting portion 43 may be used as one or more mounting target portions, and one or more gauge mounting devices 6 may be individually attached to the one or more mounting target portions.

[0102] As described above, the configuration shown in the above embodiment is an example of the content of the present disclosure. The embodiment can be combined with another known technique. It is possible to omit or change a part of the configuration of the embodiment without departing from the gist of the present disclosure.
