[0010] The following describes embodiments of the subject matter of the present disclosure with reference to the accompanying drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. Note that the subject matter of the present disclosure is not limited to the following embodiments, and any component of the embodiments may be modified or omitted within the scope of the gist of the present disclosure.

[0011] Embodiment 1 Fig. 1 is a perspective view showing an elevator guide rail centering device according to embodiment 1. Fig. 2 is a top view showing the guide rail centering device of Fig. 1. In the figure, a first guide rail 11, a second guide rail 12, a third guide rail 13, and a fourth guide rail 14 are arranged in an elevator shaft 1 as a plurality of guide rails 11 to 14.

[0012] The first guide rail 11 and the second guide rail 12 face each other in the width direction of the hoistway 1. The width direction of the hoistway 1 coincides with the left-right direction when the hoistway 1 is viewed from a landing (not shown) provided on each floor of the building. A car (not shown) is disposed between the first guide rail 11 and the second guide rail 12. The first guide rail 11 and the second guide rail 12 are used as a pair of car guide rails that guide the up-and-down movement of the car.

[0013] The third guide rail 13 and the fourth guide rail 14 face each other in the depth direction of the hoistway 1. The depth direction of the hoistway 1 is a horizontal direction perpendicular to the width direction of the hoistway 1. A counterweight (not shown) is arranged between the third guide rail 13 and the fourth guide rail 14. The third guide rail 13 and the fourth guide rail 14 are used as a pair of counterweight guide rails that guide the movement of the counterweight in the vertical direction. In this embodiment, when the hoistway 1 is viewed from above, the counterweight is arranged next to the car in the width direction of the hoistway 1.

[0014] The first guide rail 11 is disposed closer to the third guide rail 13 and the fourth guide rail 14 than the second guide rail 12. The third guide rail 13 is disposed closer to the first guide rail 11 and the second guide rail 12 than the fourth guide rail 14.

[0015] Each of the plurality of guide rails 11 to 14 has a flange portion 15 and a guide portion 16. The flange portion 15 is a plate-shaped portion arranged along the longitudinal direction of the guide rail. The guide portion 16 is a protrusion provided on the flange portion 15 along the longitudinal direction of the guide rail. The cross-sectional shape of each of the plurality of guide rails 11 to 14 is T-shaped due to the flange portion 15 and the guide portion 16. When the elevator shaft 1 is viewed from above, the center line of the guide portion 16 of each of the plurality of guide rails 11 to 14 is set on each of the guide rails 11 to 14 as a rail reference.

[0016] Each of the first guide rail 11 and the second guide rail 12 is arranged with a guide portion 16 protruding from a flange portion 15 toward the space between the first guide rail 11 and the second guide rail 12. When the elevator shaft 1 is viewed from above, the center line of each of the guide portions 16 of the first guide rail 11 and the second guide rail 12 coincides with a guide rail first reference line A set in the elevator shaft 1 along the width direction of the elevator shaft 1, as shown in FIG.

[0017] Each of the third guide rail 13 and the fourth guide rail 14 is arranged with a guide portion 16 protruding from a flange portion 15 toward the space between the third guide rail 13 and the fourth guide rail 14. When the elevator shaft 1 is viewed from above, the center line of the guide portion 16 of each of the third guide rail 13 and the fourth guide rail 14 coincides with a guide rail second reference line B set in the elevator shaft 1 along the depth direction of the elevator shaft 1, as shown in FIG.

[0018] 2, the guide section 16 of each of the plurality of guide rails 11 to 14 is formed with a pair of rail side surfaces 161 and a rail end surface 162. When the hoistway 1 is viewed from above, the pair of rail side surfaces 161 are located symmetrically with respect to the center line of the guide section 16. When the hoistway 1 is viewed from above, the rail end surface 162 is perpendicular to the center line of the guide section 16.

[0019] A pair of piano wires (not shown) is stretched vertically within the hoistway 1, and serves as a reference for centering each of the plurality of guide rails 11 to 14. In this embodiment, the pair of piano wires is stretched at positions spaced apart from each other in the width direction of the hoistway 1.

[0020] The guide rail centering device 2 is used when centering each of the multiple guide rails 11 to 14. The guide rail centering device 2 has a first main gauge 3, a second main gauge 4, a connecting body 5, and four gauge mounting devices 6.

[0021] The first main gauge 3 has a first main gauge body 31 , a first rail mounting portion 32 , and a second rail mounting portion 33 .

[0022] The first main gauge body 31 is disposed along the width direction of the elevator shaft 1. The first rail mounting portion 32 and the second rail mounting portion 33 are connected to each other via the first main gauge body 31. The first rail mounting portion 32 is attached to the first guide rail 11 by gripping the first guide rail 11. The second rail mounting portion 33 is attached to the second guide rail 12 by gripping the second guide rail 12.

[0023] The second main gauge 4 has a second main gauge body 41 , a third rail mounting portion 42 , and a fourth rail mounting portion 43 .

[0024] The second main gauge body 41 is disposed along the depth direction of the elevator shaft 1. The length of the second main gauge body 41 is shorter than the length of the first main gauge body 31.

[0025] The third rail mounting portion 42 and the fourth rail mounting portion 43 are connected to each other via the second main gauge body 41. The third rail mounting portion 42 is attached to the third guide rail 13 by gripping the third guide rail 13. The fourth rail mounting portion 43 is attached to the fourth guide rail 14 by gripping the fourth guide rail 14.

[0026] 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 has a grip main body portion 21 and a rail hook portion 22 .

[0027] The grip body 21 is shaped like a plate. In the first main gauge 3, the grip body 21 of the first rail mounting portion 32 is fixed to one end of the first main gauge body 31, and the grip body 21 of the second rail mounting portion 33 is fixed to the other end of the first main gauge body 31. In the second main gauge 4, the grip body 21 of the third rail mounting portion 42 is fixed to one end of the second main gauge body 41, and the grip body 21 of the fourth rail mounting portion 43 is fixed to the other end of the second main gauge body 41. The first main gauge 3 and the second main gauge 4 are arranged with their grip bodies 21 horizontal. A step portion 23 is provided on the grip body 21.

[0028] The rail hooking portion 22 is an arm that protrudes from the grip body portion 21. The rail hooking portion 22 is attached to the grip body portion 21 by a fastening shaft 24.

[0029] The first rail mounting portion 32 grips the first guide rail 11 by hooking the step portion 23 onto the guide portion 16 of the first guide rail 11 and the rail hooking portion 22 onto the flange portion 15 of the first guide rail 11. The second rail mounting portion 33 grips the second guide rail 12 by hooking the step portion 23 onto the guide portion 16 of the second guide rail 12 and the rail hooking portion 22 onto the flange portion 15 of the second guide rail 12. The third rail mounting portion 42 grips the third guide rail 13 by hooking the step portion 23 onto the guide portion 16 of the third guide rail 13 and the rail hooking portion 22 onto the flange portion 15 of the third guide rail 13. The fourth rail mounting portion 43 grips the fourth guide rail 14 by hooking the step portion 23 onto the guide portion 16 of the fourth guide rail 14 and hooking the rail hooking portion 22 onto the flange portion 15 of the fourth guide rail 14.

[0030] When the step portion 23 is engaged with the guide portion 16 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, the inner surface of the step portion 23 contacts one of the rail side surfaces 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 positioned so that each alignment portion 34 is aligned with the position of a pair of piano wires stretched within the elevator shaft 1. The first main gauge 3 is attached to the first guide rail 11 and the second guide rail 12 and is positioned based on the pair of piano wires, thereby aligning 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 relative to the first main gauge 3, thereby aligning the third guide rail 13 and the fourth guide rail 14, respectively.

[0033] The connecting body 5 has a plurality of sub-gauges 51 to 53, including a first sub-gauge 51, a second sub-gauge 52, and a third sub-gauge 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 connecting body 5 positions the second main gauge 4 relative 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 mounting devices 6 are individually attached to 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. 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 that individually correspond to the four gauge mounting devices 6. Each gauge mounting device 6 is attached to a 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 device 6. As a result, any one of the first sub-gauge 51, the second sub-gauge 52, and the third sub-gauge 53 is mounted via the gauge mounting device 6 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.

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

[0038] Each gauge mounting device 6 is detachably mounted to a 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 mounting fixtures 61. Furthermore, each gauge mounting device 6 uses the guide rail among the first guide rail, the second guide rail, the third guide rail, and the fourth guide rail to which the corresponding mounting target portion is mounted as a reference guide rail.

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

[0040] The gauge mounting devices 6 all have the same configuration. Here, we will explain the configuration of the gauge mounting device 6 attached to the first rail mounting portion 32, that is, the configuration of the gauge mounting device 6 with the first rail mounting portion 32 as the mounting target and the first guide rail 11 as the reference guide rail.

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

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

[0043] The attachment 7 is attached to the first rail mounting part 32 in a state where it overlaps the grip body part 21 of the first rail mounting part 32. The grip body part 21 of the first rail mounting part 32 is provided with a plurality of fixture fastening holes (not shown) for fastening each fixture 61. In this embodiment, the grip body part 21 is provided with a plurality of screw holes as the fixture fastening holes, into which the respective fixtures 61 are screwed.

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

[0045] Any 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 mounting device 6 having the first rail mounting portion 32 as the mounting target, the first sub-gauge 51 is connected to the connector 8.

[0046] The attachment 7 is a plate having a first surface 71 and a second surface 72 facing opposite directions. 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 7a, a rear end 7b, a first side 7c, and a second side 7d. Of the two ends of the attachment 7 in the front-to-rear direction, one end is the front end 7a and the other end is the rear end 7b. Furthermore, of the two ends of the attachment 7 in the left-to-right direction, one end is the first side 7c and the other end is the second side 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 mounting fixture through holes 73a and a plurality of second mounting fixture through holes 73b. In this embodiment, two first mounting fixture through holes 73a and two second mounting fixture through holes 73b are provided in the attachment 7. The first mounting fixture through holes 73a and the second mounting fixture through holes 73b are located at positions spaced apart from each other in the left-right direction of the attachment 7. The two first mounting fixture through holes 73a are located at positions spaced apart from each other in the front-rear direction of the attachment 7. The two second mounting fixture through holes 73b are also located at positions spaced apart from each other in the front-rear direction of the attachment 7.

[0049] The gauge mounting device 6, which has the first rail mounting portion 32 as the mounting target, uses the first guide rail 11 as the reference guide rail. The attachment 7 can be mounted to the first rail mounting portion 32 with the orientations of the first surface 71 and the second surface 72 reversed, with the front end 7a facing the first guide rail 11, which is the reference guide rail. This makes it possible to change the mounting state of the attachment 7 relative to the first rail mounting portion 32 between a first mounting state and a second mounting state.

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

[0051] In the gauge mounting device 6, which has the first rail mounting portion 32 as the mounting target, the second surface 72 overlaps the first rail mounting portion 32 in the first mounting state, and the first surface 71 overlaps the first rail mounting portion 32 in the second mounting state. Figure 3 shows the attachment 7 in the first mounting state. Whether the attachment 7 is in the first mounting state or the second mounting state, the left-right direction of the attachment 7 coincides with the width direction of the guide portion 16 of the first guide rail 11.

[0052] The positions of the first side portion 7c and the second side portion 7d relative to the first rail mounting portion 32 are switched between when the attachment 7 is in the first mounting state and when the attachment 7 is in the second mounting state. Whether the attachment 7 is in the first mounting state or the second mounting state, each mounting fixture 61 is screwed into the same screw hole in the first rail mounting 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 7 is in the first attachment state, the first interference avoidance hole 74a prevents interference between the attachment 7 and the fastening pin 24 in the first rail attachment portion 32. In the first attachment state, as shown in FIG. 3, the fastening pin 24 is located inside the first interference avoidance hole 74a.

[0054] When the attachment 7 is in the second attachment state, the second interference avoidance hole 74b prevents interference between the attachment 7 and the fastening shaft 24 in the first rail attachment portion 32. 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 mounting holes 75a and a plurality of second connector mounting holes 75b as a plurality of connector mounting holes 75. Connectors 8 can be selectively attached to the plurality of connector mounting holes 75.

[0056] The connectors 8 can be selectively attached to the multiple first connector mounting holes 75a when the attachment 7 is in the first mounting state. The position of each first connector mounting hole 75a is determined based on the positions of the multiple first mounting hole through holes 73a. In this embodiment, two first connector mounting holes 75a are provided on the first side portion 7c of the attachment 7. Also, in this embodiment, the two first connector mounting holes 75a are provided on the attachment 7 at an interval from each other in the front-to-rear direction of the attachment 7.

[0057] The connectors 8 can be selectively attached to the multiple second connector mounting holes 75b when the attachment 7 is in the second mounting state. The position of each second connector mounting hole 75b is determined based on the positions of the multiple second mounting hole through holes 73b. In this embodiment, two second connector mounting holes 75b are provided on the second side portion 7d of the attachment 7. Also, in this embodiment, the two second connector mounting holes 75b are provided on the attachment 7 at an interval from each other in the front-to-rear direction of the attachment 7.

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

[0059] An attachment indicator 77 is provided on each of the first surface 71 and the second surface 72. The attachment indicator 77 is an indicator that helps identify the connector mounting hole 75 that should be selected depending on differences in the layout of the plurality of guide rails 11-14, i.e., differences in the positional relationship of the plurality of guide rails 11-14.

[0060] Here, consider a case where the size of the first guide rail 11 is a first size, and a 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 attachment 7 when the size of the first guide rail 11 in Fig. 1 is a first size. Fig. 6 is a top view showing the attachment 7 when the size of the first guide rail 11 in Fig. 1 is a second size.

[0062] When 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 differs between the first size and the second size. In this 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 multiple guide rails 11 to 14, the center line of the guide section 16 when the elevator shaft 1 is viewed from above is set as the rail reference. The first guide rail 11 is centered by aligning the rail reference of the first guide rail 11, i.e., the center line of the first guide rail 11, with the guide rail first reference line A shown in FIG.

[0064] Meanwhile, the first rail mounting portion 32 is attached to the first guide rail 11 by hooking the step portion 23 onto the guide portion 16 of the first guide rail 11. The position of the pair of rail side surfaces 161 formed on the guide portion 16 changes relative 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 relative to the center line of the first guide rail 11 differs depending on whether the size of the first guide rail 11 is a first size or a second size, depending on the difference between the first size and the second size.

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

[0066] When the size of the first guide rail 11 is the first size, the attachment 7 is placed in a first attachment state as shown in Fig. 5. The positions of the first connector attachment holes 75a relative to the center line of the first guide rail 11 at this time are referred to as first state attachment hole positions.

[0067] When the size of the first guide rail 11 is the second size, the attachment 7 is placed in the forward second attachment state as shown in Fig. 6. At this time, the positions of the second connector attachment holes 75b relative to the center line of the first guide rail 11 are referred to as second state attachment hole positions.

[0068] As described above, the position of the first rail mounting portion 32 relative to the center line of the first guide rail 11 differs depending on the difference between the first and second sizes. In the attachment 7, the position of each second connector mounting hole 75b relative to the second mounting tool through hole 73b differs from the position of each first connector mounting hole 75a relative to the first mounting tool through hole 73a depending on the difference between the first size and the second size. This causes the first state mounting hole position and the second state mounting hole position to coincide with each other relative to the center line of the first guide rail 11.

[0069] That is, in the attachment 7, the position of each first connector mounting hole 75a relative to the first mounting fixture through hole 73a and the position of each first connector mounting hole 75a relative to the first mounting fixture through hole 73a are determined so that the first state mounting hole position and the second state mounting hole position coincide with the center line of the first guide rail 11. In this embodiment, the position of each first connector mounting hole 75a relative to the first mounting fixture through hole 73a and the position of each first connector mounting hole 75a relative to the first mounting fixture through hole 73a are determined so that the first state mounting hole position and the second state mounting hole position coincide with positions on the center line of the first guide rail 11.

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

[0071] The position of each second connector mounting hole 75b relative to the second mounting tool through hole 73b is determined in accordance with the second size of the first guide rail 11. Specifically, a second mounting distance L2, which is the distance from the center of the second mounting tool through hole 73b in the left-right direction of the attachment 7 to the center of each second connector mounting hole 75b, is determined in accordance with 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 (t1-t2) / 2 closer to the center line of the first guide rail 11 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 is closer to 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 the center line of the first guide rail 11.

[0075] When the attachment 7 is in the first attachment state, the attachment 7 is positioned such that the position of the first cutout portion 76a is aligned with the position of the step portion 23 of the first rail attachment portion 32. As a result, when the attachment 7 is in the first attachment state, the first cutout portion 76a engages with the first guide rail 11, as shown in Fig. 5. When the first cutout portion 76a engages with the first guide rail 11, the inner surface of the first cutout portion 76a contacts one rail side surface 161 and a rail end surface 162 of the first guide rail 11.

[0076] When the attachment 7 is in the second attachment state, the attachment 7 is positioned such that the position of the second cutout portion 76b is aligned with the position of the step portion 23 of the first rail attachment portion 32. As a result, when the attachment 7 is in the second attachment state, the second cutout portion 76b engages with the first guide rail 11, as shown in Fig. 6. When the second cutout portion 76b engages with the first guide rail 11, the inner surface of the second cutout portion 76b contacts one rail side surface 161 and a rail end surface 162 of the first guide rail 11.

[0077] Here, the distance from the center of the first mounting fixture through hole 73a to the first cutout portion 76a in the left-right direction of the attachment 7 is defined as a first cutout distance L11. Also, the distance from the center of the second mounting fixture through hole 73b to the second cutout portion 76b in the left-right direction of the attachment 7 is defined as a second cutout distance L21. In this case, the first cutout distance L11 and the second cutout distance L21 are the same distance.

[0078] Furthermore, the distance from the first cutout portion 76a to the center of each first connector mounting hole 75a in the left-right direction of the attachment 7 is defined as a first adjustment distance L12. Furthermore, the distance from the second cutout portion 76b to the center of each second connector mounting hole 75b in the left-right direction of the attachment 7 is defined as a second adjustment distance L22. In this case, the first adjustment distance L12 and the second adjustment distance L22 differ from each other depending on the difference between the first size and the second size. In this embodiment, the difference between the first adjustment distance L12 and the second adjustment distance L22 is (t1-t2) / 2.

[0079] The first mounting distance L1 is the first cutout distance L11 plus the first adjustment distance L12. The second mounting distance L2 is the second cutout distance L21 plus the second adjustment distance L22.

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

[0081] When comparing two gauge mounting devices 6 that have the first rail mounting portion 32 and the second rail mounting portion 33 as mounting targets, the orientation of the front end portion 7a of the attachment 7 is opposite between one gauge mounting device 6 and the other gauge mounting device 6, as shown in Fig. 2. Also, when comparing two gauge mounting devices 6 that have the third rail mounting portion 42 and the fourth rail mounting portion 43 as mounting targets, the orientation of the front end portion 7a of the attachment 7 is opposite between one gauge mounting device 6 and the other gauge mounting device 6.

[0082] Therefore, in the two gauge mounting devices 6 having the first rail mounting portion 32 and the third rail mounting portion 42 as the mounting target portions, the surface that overlaps with the mounting target portions in the first mounting state is the second surface 72, and the surface that overlaps with the mounting target portions in the second mounting state is the first surface 71. In contrast, in the two gauge mounting devices 6 having the second rail mounting portion 33 and the fourth rail mounting portion 43 as the mounting target portions, the surface that overlaps with the mounting target portions in the first mounting state is the first surface 71, and the surface that overlaps with the mounting target portions in the second mounting state is the second surface 72.

[0083] The attachment display 77 in each gauge mounting device 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 state first surface indicator 77a is provided around the plurality of first connector mounting holes 75a on the first surface 71. The second state first surface indicator 77b is provided around the plurality of second connector mounting holes 75b on the first surface 71. The first state second surface indicator 77c is provided around the plurality of first connector mounting holes 75a on the second surface 72, as shown in Fig. 6. The second state second surface indicator 77d is provided around the plurality of second connector mounting holes 75b on the second surface 72.

[0085] In the two gauge mounting devices 6 having the first rail mounting portion 32 and the third rail mounting portion 42 as mounting target portions, the first connector mounting hole 75a to be selected from the plurality of first connector mounting holes 75a in the first mounting state is identified based on the content of the first state first surface indicator 77a. Also, in the two gauge mounting devices 6 having the first rail mounting portion 32 and the third rail mounting portion 42 as mounting target portions, the second connector mounting hole 75b to be selected from the plurality of second connector mounting holes 75b in the second mounting state is identified based on the content of the second state second surface indicator 77d.

[0086] In the two gauge mounting devices 6 having the second rail mounting portion 33 and the fourth rail mounting portion 43 as mounting target portions, the first connector mounting hole 75a to be selected from the plurality of first connector mounting holes 75a in the first mounting state is identified based on the content of the first state second surface indicator 77c. Also, in the two gauge mounting devices 6 having the second rail mounting portion 33 and the fourth rail mounting portion 43 as mounting target portions, the second connector mounting hole 75b to be selected from the plurality of second connector mounting holes 75b in the second mounting state is identified based on the content of the second state first surface indicator 77b.

[0087] The plurality of first connector mounting holes 75a are distinguished from one another, and the plurality of second connector mounting holes 75b are distinguished from one another, for example, by the color coding of the attachment indicators 77.

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

[0089] When the size of each of the guide rails 11 to 14 is the second size, the attachment 7 is placed in a second attachment state relative to the corresponding attachment target portion in each gauge mounting device 6. In this case, in each gauge mounting device 6, the connector 8 is attached to a second connector mounting hole 75b selected from the plurality of second connector mounting holes 75b.

[0090] As a result, whether the size of each of the guide rails 11 to 14 is the first size or the second size, the position of the connector 8 relative to the center line of the reference guide rail is the same in each gauge mounting device 6. Therefore, the positional relationship of the connector 8 in the four gauge mounting devices 6 does not change whether the size of each of the guide rails 11 to 14 is the first size or the second size. As a result, each of the first sub-gauge 51, second sub-gauge 52, and third sub-gauge 53 can be used both when the size of each of the guide rails 11 to 14 is the first size and when the size of each of the guide rails 11 to 14 is the second size.

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

[0092] In each gauge mounting device 6, the connector mounting hole 75 is selected from a plurality of first connector mounting holes 75a when the mounting state of the attachment 7 is in the first mounting state, and is selected from a plurality of second connector mounting holes 75a when the mounting state of the attachment 7 is in the second mounting state. The connector mounting holes 75 in each gauge mounting device 6 are selected so that the distance between each connector 8 is the same in the two types of elevators. This makes it possible for each of the first sub-gauge 51, second sub-gauge 52, and third sub-gauge 53 to be used in both types of elevators.

[0093] In this guide rail centering device 2, each gauge mounting device 6 has an attachment 7 and a connector 8. The attachment 7 is detachably attached to a corresponding mounting target portion. The connector 8 is detachably attached to the attachment 7. One of the multiple sub-gauges 51-53 is connected to the connector 8. The attachment 7 is provided with multiple connector mounting holes 75 to which the connector 8 can be selectively attached. Therefore, by changing the connector mounting hole 75 to which the connector 8 is attached, the position of the connector 8 relative to the reference guide rail to which the mounting target portion is attached can be easily changed. This allows the connector 8 of each gauge mounting device 6 to be positioned so that each of the multiple sub-gauges 51-53 can be connected, in either of two types of elevators in which the positional relationships of the multiple guide rails 11-14 are different from each other. Therefore, each of the sub-gauges 51-53 can be used for both of two types of elevators in which the positional relationships of the multiple guide rails 11-14 are different from each other. This eliminates the need to use different types of sub-gauges for each of the two types of elevators, making it possible to reduce the number of types of sub-gauges.

[0094] The attachment state of the attachment 7 relative 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 reference guide rail, one of the first surface 71 and the second surface 72 overlaps the attachment target portion, and is attached to the attachment target portion by the attachment tool 61 passed through the first attachment tool through-hole 73a. When the attachment state of the attachment 7 is the second attachment state, the attachment 7 faces the reference guide rail, the other of the first surface 71 and the second surface 72 overlaps the attachment target portion, and is attached to the attachment target portion by the attachment tool 61 passed through the second attachment tool through-hole 73b. The positions of the multiple first connector attachment holes 75a relative to the first attachment tool through-hole 73a are determined according to the first size. The positions of the multiple second connector attachment holes 75b relative to the second attachment tool through-hole 73b are determined according to the second size. Therefore, even if the position of the attachment portion relative to the center line of the first guide rail 11 differs depending on the difference between the first size and the second size, the position of the connector 8 can be aligned with the center line of the reference guide rail. This allows the sub-gauges 51 to 53 to be used interchangeably regardless of whether the size of the reference guide rail is the first size or the second size. This eliminates the need to use different types of sub-gauges depending on the size of the reference guide rail, and allows the number of types of sub-gauges to be reduced.

[0095] The attachment 7 is also provided with a first cutout portion 76a and a second cutout portion 76b. When the attachment 7 is in the first mounting state, the first cutout portion 76a engages with the reference guide rail. When the attachment 7 is in the second mounting state, the second cutout portion 76b engages with the reference guide rail. This allows the attachment 7 to be positioned relative to the reference guide rail directly by bringing the attachment 7 into contact with the reference guide rail. This allows for more accurate positioning of the attachment 7 relative to the reference guide rail.

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

[0097] In the above embodiment, the number of first connector mounting holes 75a in the attachment 7 is two. However, the number of first connector mounting holes 75a in the attachment 7 is not limited to two. The number of first connector mounting holes 75a in the attachment 7 may be three or more. In this way, multiple sub-gauges can be used in even more types of elevators in which the positional relationships between the multiple guide rails 11-14 are different from one another.

[0098] Furthermore, in the above embodiment, the number of second connector mounting holes 75b in the attachment 7 is two. However, the number of second connector mounting holes 75b in the attachment 7 is not limited to two. The number of second connector mounting holes 75b in the attachment 7 may be three or more. In this way, multiple sub-gauges can be used in even more types of elevators in which the positional relationships between the multiple guide rails 11-14 differ from one another.

[0099] In the above embodiment, the attachment 7 is provided with the first cutout portion 76a that engages with the reference guide rail in the first attachment state. However, if the attachment 7 can be attached to a predetermined position on the attachment target portion, the attachment 7 does not need to have the first cutout portion 76a.

[0100] In the above embodiment, the attachment 7 is provided with the second cutout portion 76b that engages with the reference guide rail in the second attachment state. However, if the attachment 7 can be attached to a predetermined position on the attachment target portion, the attachment 7 does not need to have the second cutout portion 76b.

[0101] In the above embodiment, 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 each serve as a mounting target for 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 rail mounting portions that are not the mounting target for the gauge mounting device 6. For example, the third rail mounting portion 42 and the fourth rail mounting portion 43 may not be the mounting target for the gauge mounting device 6, and the gauge mounting device 6 may be mountable 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 is not attached, and one of the multiple sub-gauges 51 to 53 is connected to the connector 8 directly attached to the rail mounting portion. This also reduces the number of types of sub-gauges. Therefore, at least 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 one or more mounting target portions.

[0102] The configurations described in the above embodiments are merely examples of the contents of the present disclosure. The embodiments can be combined with other known technologies. Part of the configuration of the embodiments can be omitted or modified without departing from the gist of the present disclosure. [Explanation of symbols]
