DETAILED DESCRIPTION OF THE INVENTION

[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 1 is a vertical cross-sectional view showing an elevator installation template device according to the first embodiment installed at the top of a hoistway. In the figure, a hoistway 102 is provided in a building 101. A hall entrance 103 is provided at each landing on each floor of the building 101. On each floor, the space of the hoistway 102 is open to the landing through the hall entrance 103. The frontage direction of the hall entrance 103 on each floor is parallel to the width direction of the hoistway 102.

[0012] A plurality of lifting beams 104 are fixed to the top of the hoistway 102 as fixed members. Each lifting beam 104 is arranged horizontally and parallel to one another. In this embodiment, each lifting beam 104 is arranged along the width direction of the hoistway 102. Also, in this embodiment, two lifting beams 104 are arranged spaced apart from one another in the depth direction of the hoistway 102. The depth direction of the hoistway 102 is a horizontal direction perpendicular to the width direction of the hoistway 102. In this embodiment, H-shaped steel is used as the lifting beams 104.

[0013] When installing an elevator in a hoistway 102, an installation template device 1 is attached to a plurality of lifting beams 104 to position objects to be installed in the hoistway 102. In this embodiment, the objects to be positioned are unillustrated landing thresholds installed at the bottom of the landing entrances 103 on each floor, and a pair of unillustrated car guide rails installed opposite each other in the width direction of the hoistway 102. The installation template device 1 is attached to each lifting beam 104, and is thereby positioned at the top of the hoistway 102.

[0014] A plurality of plumb lines 3, each of which individually suspends a weight 2, are connected to the installation template device 1. As a result, each plumb line 3 is stretched vertically from the installation template device 1 to the hoistway 102. For example, piano wire is used as the plumb line 3. When the hoistway 102 is viewed from above, the position of each plumb line 3 is individually set to a position that serves as a reference for positioning each object in the hoistway 102. As a result, each plumb line 3 serves as a reference for positioning each object.

[0015] In this embodiment, of the multiple plumb lines 3, a pair of plumb lines 3 that serve as a reference for positioning the landing threshold are stretched in the hoistway 102 as a pair of landing threshold plumb lines 3a. Also, in this embodiment, of the multiple plumb lines 3, a pair of plumb lines 3 that serve as a reference for positioning a pair of car guide rails are stretched in the hoistway 102 as a pair of car rail plumb lines 3b.

[0016] Figure 2 is a perspective view showing the installation template device 1 of Figure 1. The installation template device 1 has a plurality of support members 4, a plurality of ruler members 5, a plurality of support fixtures 6, and a plurality of ruler fixtures 7.

[0017] Each support member 4 is placed on each lift beam 104, straddling multiple lift beams 104. In this embodiment, two support members 4 are placed on each lift beam 104, straddling two lift beams 104. Each support member 4 is arranged along the depth direction of the hoistway 102. Each support member 4 is arranged spaced apart from each other in the width direction of the hoistway 102. Each support member 4 is attached to each lift beam 104 by multiple support fixtures 6.

[0018] Each ruler member 5 is placed across two support members 4. Each ruler member 5 is arranged along the width direction of the elevator shaft 102. The multiple ruler members 5 are arranged spaced apart from each other in the depth direction of the elevator shaft 102. Each ruler member 5 is attached to each support member 4 by multiple ruler attachments 7.

[0019] In the present embodiment, two ruler members 5 are attached to each support member 4. Furthermore, in the present embodiment, of the two ruler members 5, one ruler member 5 is a platform threshold ruler member 5a, and the other ruler member 5 is a car rail ruler member 5b. In the present embodiment, when the hoistway 102 is viewed from above, the platform threshold ruler member 5a is arranged in a position closer to the platform entrance / exit 103 than the car rail ruler member 5b. Furthermore, in the present embodiment, a pair of platform threshold plumb lines 3a are connected to the platform threshold ruler members 5a, and a pair of car rail plumb lines 3b are connected to the car rail ruler members 5b.

[0020] Each ruler member 5 has a ruler member body 51, a plurality of linking members 52, and a pair of connectors 53. The plurality of linking members 52 and the pair of connectors 53 are attached to the ruler member body 51.

[0021] The ruler member main body 51 has a plurality of ruler blocks 54. The plurality of ruler blocks 54 are detachably connected to one another in succession in the longitudinal direction of the ruler member 5. Each ruler block 54 is arranged along the longitudinal direction of the ruler member 5. The length of the ruler member main body 51 can be adjusted by adjusting the number of ruler blocks 54.

[0022] In each ruler member 5, one of the multiple ruler blocks 54 is a base ruler block 54a, and the ruler blocks 54 other than the base ruler block 54a are extended ruler blocks 54b. The length of the base ruler block 54a is longer than the length of the extended ruler blocks 54b. The lengths of the extended ruler blocks 54b are the same. The length of the ruler member main body 51 is adjusted by adjusting the number of extended ruler blocks 54b.

[0023] In this embodiment, the length of the ruler member body 51 of the landing threshold ruler member 5a is shorter than the length of the ruler member body 51 of the car rail ruler member 5b.

[0024] In the ruler member main body 51 of the landing threshold ruler member 5a, one extended ruler block 54b is connected to each end of the base ruler block 54a. As a result, in the ruler member main body 51 of the landing threshold ruler member 5a, three ruler blocks 54 are connected in series.

[0025] Meanwhile, in the ruler member main body 51 of the car rail ruler member 5b, two extension ruler blocks 54b are connected in succession to each end of the base ruler block 54a. As a result, five ruler blocks 54 are connected in succession in the ruler member main body 51 of the car rail ruler member 5b.

[0026] Each connector 52 connects two adjacent ruler blocks 54. Each connector 52 is attached to the ruler member main body 51 in a state where it covers the boundary between the two adjacent ruler blocks 54.

[0027] The pair of connectors 53 are individually attached to both ends of the ruler member main body 51 by fastening bolts 530. Therefore, one of the pair of connectors 53 is attached to the extension ruler block 54b located at one end of the ruler member main body 51. The other of the pair of connectors 53 is attached to the extension ruler block 54b located at the other end of the ruler member main body 51. A plumb line 3 is individually connected to each connector 53. When the base ruler block 54a is located at the end of the ruler member main body 51, the connector 53 is attached to the base ruler block 54a.

[0028] In the landing threshold ruler member 5a, a pair of landing threshold plumb lines 3a are individually connected to a pair of connectors 53. In the car rail ruler member 5b, a pair of car rail plumb lines 3b are individually connected to a pair of connectors 53.

[0029] Fig. 3 is a perspective view showing the base ruler block 54a included in each ruler member 5 of Fig. 2. Fig. 4 is a perspective view showing the extension ruler block 54b included in each ruler member 5 of Fig. 2. Each of the base ruler block 54a and the extension ruler block 54b, i.e., each ruler block 54, has a back plate portion 541 and a pair of side plate portions 542.

[0030] The back plate portion 541 and the pair of side plate portions 542 are each arranged along the longitudinal direction of the ruler member 5. The side plate portions 542 are individually provided on both edge portions of the back plate portion 541. The pair of side plate portions 542 face each other across a space in the width direction of the back plate portion 541. As a result, the cross-sectional shape of the ruler block 54 in a plane perpendicular to the longitudinal direction of the ruler member 5 is C-shaped due to the back plate portion 541 and the pair of side plate portions 542. In each ruler block 54, an opening along the longitudinal direction of the ruler member 5 is formed between the edges of the pair of side plate portions 542. Each ruler block 54 is arranged with the back plate portion 541 facing upward and the opening of the ruler block 54 facing downward. The width direction of each ruler block 54 coincides with the width direction of the back plate portion 541, and the thickness direction of each ruler block 54 coincides with the thickness direction of the back plate portion 541.

[0031] At both ends of each ruler block 54, a connector mounting hole 56 is provided in the back plate portion 541, and a linking mounting hole 57 is provided in each of the pair of side plate portions 542. The connector mounting hole 56 is a through hole that passes through the back plate portion 541 in the thickness direction of the back plate portion 541. The linking mounting hole 57 is a through hole that passes through the side plate portion 542 in the thickness direction of the side plate portion 542. In this embodiment, the linking mounting hole 57 is a screw hole.

[0032] Fig. 5 is an enlarged perspective view showing the ruler member main body 51 and the connector 53 of the landing threshold ruler member 5a of Fig. 2. Fig. 6 is an enlarged perspective view showing the state in which the extension ruler block 54b of Fig. 5 has been detached from the base ruler block 54a. Fig. 7 is an enlarged perspective view showing the end of the base ruler block 54a of Fig. 6.

[0033] Here, the only difference between the configuration of the car rail ruler member 5b and the configuration of the landing threshold ruler member 5a is the number of extension ruler blocks 54b. Therefore, the configuration common to both the landing threshold ruler member 5a and the car rail ruler member 5b will be described as the configuration of the ruler member 5. Furthermore, except for the fact that the length of the base ruler block 54a is longer than the length of the extension ruler block 54b, the configuration of the base ruler block 54a is the same as the configuration of the extension ruler block 54b. Therefore, hereinafter, except when it is necessary to distinguish between the base ruler block 54a and the extension ruler block 54b, both the base ruler block 54a and the extension ruler block 54b will be described as ruler blocks 54.

[0034] In each ruler member 5, at the boundary between two adjacent ruler blocks 54, the end faces of the two ruler blocks 54 are in contact with each other, as shown in Fig. 5. That is, at the boundary between two adjacent ruler blocks 54, the end faces of the back plate portions 541 of the two ruler blocks 54 are in contact with each other, and the end faces of the side plate portions 542 of the two ruler blocks 54 are in contact with each other. As a result, in each ruler member 5, multiple ruler blocks 54 are arranged in a straight line.

[0035] In each ruler member 5, a plurality of fitting structures 58 are provided at the boundary between two adjacent ruler blocks 54. As shown in FIG. 6, each fitting structure 58 has a protrusion 581 and a recess 582. The protrusion 581 protrudes from one of the two adjacent ruler blocks 54. The recess 582 is formed in the other of the two adjacent ruler blocks 54. When the two ruler blocks 54 are connected to each other, the protrusion 581 fits into the recess 582 in each fitting structure 58.

[0036] The fitting structure 58 is provided at the boundary between the back plate portions 541 of each of two adjacent ruler blocks 54, and at the boundary between the side plate portions 542 of each of two adjacent ruler blocks 54.

[0037] Here, in the ruler member main body 51, the width direction of the ruler block 54 is the X direction, and the thickness direction of the ruler block 54 is the Y direction. The longitudinal direction of the ruler member 5 is the Z direction, which is perpendicular to both the X direction and the Y direction. In this case, when two ruler blocks 54 are connected to each other, the fitting structure 58 provided at the boundary between the back plate portions 541 prevents the two ruler blocks 54 from shifting in position relative to each other in the X direction. Furthermore, when two ruler blocks 54 are connected to each other, the fitting structure 58 provided at the boundary between the side plate portions 542 prevents the two ruler blocks 54 from shifting in position relative to each other in the Y direction.

[0038] Fig. 8 is an enlarged perspective view showing the connector 52 in the landing threshold ruler member 5a in Fig. 2. Fig. 9 is an exploded perspective view showing the connector 52 in Fig. 8 detached from the ruler member main body 51. The configuration of each connector 52 is the same in each of the landing threshold ruler member 5a and the car rail ruler member 5b. Each connector 52 has a connector main body 521, a first fastening bolt 522, and a second fastening bolt 523.

[0039] The connector body 521 is disposed across the boundary between two adjacent ruler blocks 54. The connector body 521 is fitted into the ruler member body 51 in a state where it covers the boundary between the two adjacent ruler blocks 54. When the connector body 521 is fitted into the ruler member body 51, the longitudinal direction of the connector body 521 coincides with the longitudinal direction of the ruler member 5.

[0040] The connector main body 521 has a first overlapping plate portion 521a and a pair of second overlapping plate portions 521b. The first overlapping plate portion 521a is a plate-shaped portion extending along the longitudinal direction of the connector main body 521. The second overlapping plate portions 521b are individually provided on both edge portions of the first overlapping plate portion 521a. The pair of second overlapping plate portions 521b face each other in the width direction of the first overlapping plate portion 521a. As a result, the cross-sectional shape of the connector main body 521 in a plane perpendicular to the longitudinal direction of the connector main body 521 is U-shaped due to the first overlapping plate portion 521a and the pair of second overlapping plate portions 521b. In this embodiment, the connector main body 521 is formed by bending a single raw material plate.

[0041] A first through hole 524 and a second through hole 525 are provided in each of the pair of second overlapping plate portions 521b of the connector main body 521. Each of the first through hole 524 and the second through hole 525 is a through hole that penetrates the second overlapping plate portion 521b.

[0042] The first through hole 524 is provided at one longitudinal end of the connector body 521. The second through hole 525 is provided at the other longitudinal end of the connector body 521. When the connector body 521 is fitted into the ruler member body 51, covering the boundary between the two ruler blocks 54, the first through hole 524 overlaps the connecting mounting hole 57 of one ruler block 54, and the second through hole 525 overlaps the connecting mounting hole 57 of the other ruler block 54.

[0043] The first fastening bolt 522 is a first block fastening member that fastens the connector body 521 to one of the two ruler blocks 54. The connector body 521 is fastened to one of the ruler blocks 54 by threading the first fastening bolt 522 passed through the first through hole 524 into the connecting mounting hole 57 of one of the ruler blocks 54. In this embodiment, the connector body 521 is fastened to one of the ruler blocks 54 only by the first fastening bolt 522 passed through one of the two first through holes 524 provided in the connector body 521.

[0044] The second fastening bolt 523 is a second block fastening member that fastens the connector main body 521 to the other of the two ruler blocks 54. The connector main body 521 is fastened to the other ruler block 54 by the second fastening bolt 523 passing through the second through hole 525 being screwed into the connecting mounting hole 57 of the other ruler block 54. In this embodiment, the connector main body 521 is fastened to the other ruler block 54 only by the second fastening bolt 523 passing through one of the two second through holes 525 provided in the connector main body 521.

[0045] When the two ruler blocks 54 are connected to each other by the connector 52, the two ruler blocks 54 are prevented from moving apart in the Z direction. This keeps the protrusions 581 of each fitting structure 58 fitted into the recesses 582.

[0046] Fig. 10 is a perspective view showing the connector 53 of Fig. 2. Fig. 11 is an enlarged perspective view showing the connector 53 of Fig. 10 attached to the ruler member main body 51. Note that part of the connector 53 is omitted in Fig. 11. Each connector 53 has a protruding member 531 and a connector main body 532.

[0047] The protruding member 531 is a plate-like member arranged along the longitudinal direction of the ruler member 5. The protruding member 531 is detachably attached to the ruler block 54 in a state where it protrudes from the ruler member main body 51 in the longitudinal direction of the ruler member 5. In this embodiment, the protruding member 531 is attached to the extended ruler block 54b. A portion of the protruding member 531 is inserted inside the ruler block 54 located at the end of the ruler member main body 51. The remaining portion of the protruding member 531 protrudes from the ruler block 54 located at the end of the ruler member main body 51.

[0048] 10, the protruding member 531 is provided with a screw hole 533 and a plurality of adjustment holes 534. The screw hole 533 is provided in a portion of the protruding member 531 that is inserted into the inside of the ruler block 54. The plurality of adjustment holes 534 are provided in a portion of the protruding member 531 that protrudes from the ruler block 54.

[0049] Each adjustment hole 534 is a through hole that penetrates the protruding member 531. The multiple adjustment holes 534 are provided in the protruding member 531 at intervals from one another in the longitudinal direction of the ruler member 5. The intervals between the multiple adjustment holes 534 are shorter than the dimensions of the extension ruler blocks 54b in the longitudinal direction of the ruler member 5. In this embodiment, the multiple adjustment holes 534 are arranged at equal intervals in the longitudinal direction of the ruler member main body 51. Also, in this embodiment, the center-to-center distance between two adjacent adjustment holes 534 is set to several tens of mm.

[0050] The protruding member 531 is attached to the ruler block 54 located at the end of the ruler member main body 51 by threading a fastening bolt 530 passed through a connector mounting hole 56 of the ruler block 54 into a threaded hole 533 of the protruding member 531. This makes the protruding member 531 detachable from the ruler block 54.

[0051] The connector body 532 is detachably attached to the protruding member 531. The connector body 532 is attached to the protruding member 531 while being selectively disposed in one of a plurality of adjustment holes 534. The position of the connector body 532 relative to the protruding member 531 is adjusted by changing the adjustment hole 534 in which the connector body 532 is disposed, among the plurality of adjustment holes 534. The distance from the end of the ruler member body 51 to the connector body 532 is adjusted by adjusting the position of the connector body 532 relative to the protruding member 531.

[0052] The plumb line 3 is connected to the connector body 532. The connection position of the plumb line 3 relative to the connector 53 is adjusted by adjusting the position of the connector body 532 relative to the protruding member 531. In each ruler member 5, the distance between the pair of plumb lines 3 is adjusted by adjusting the number of expansion ruler blocks 54b and adjusting the position of the connector body 532 relative to the protruding member 531 in each connector 53.

[0053] As shown in FIG. 10, the connector body 532 has a mounting bolt 532a, a mounting nut 532b, and a connecting nut 532c.

[0054] The threaded portion of mounting bolt 532a is passed through one of the plurality of adjustment holes 534. A mounting nut 532b is screwed onto the threaded portion of mounting bolt 532a. Mounting bolt 532a is attached to protruding member 531 by fastening protruding member 531 between the head of mounting bolt 532a and mounting nut 532b. This makes connector main body 532 detachable from protruding member 531.

[0055] The connecting nut 532c is screwed onto the threaded portion of the mounting bolt 532a attached to the protruding member 531. In this embodiment, a butterfly nut is used as the connecting nut 532c. The plumb line 3 is connected to the connector main body 532 by tightening the connecting nut 532c onto the mounting nut 532b.

[0056] 2, each support member 4 has a support member body 41 and a connector 42. The connector 42 is attached to the support member body 41.

[0057] The support member main body 41 has a plurality of support blocks 43. The plurality of support blocks 43 are detachably connected to one another in succession in the longitudinal direction of the support member 4. Each support block 43 is arranged along the longitudinal direction of the support member 4. The length of the support member main body 41 can be adjusted by adjusting the number of support blocks 43.

[0058] In each support member 4, one of the multiple support blocks 43 is a base support block 43a, and the other support blocks 43 are extended support blocks 43b. The length of the base support block 43a is longer than the length of the extended support block 43b.

[0059] In this embodiment, the lengths of the support members 4 are set to be the same. Also, in this embodiment, in each support member 4, one base support block 43a is connected to one extension support block 43b. The configuration of the base support block 43a is similar to the configuration of the base ruler block 54a, and the configuration of the extension support block 43b is similar to the configuration of the extension ruler block 54b. Each support member 4 is arranged with the open portion of the support block 43 facing downward.

[0060] The connector 42 connects two adjacent support blocks 43. The connector 42 is attached to the support member main body 41 in a state where it covers the boundary between the two adjacent support blocks 43. The configuration of the connector 42 in the support member 4 is similar to the configuration of the connector 52 in the ruler member 5.

[0061] 2, each support fixture 6 is disposed at a position where the support member body 41 intersects with the lifting beam 104. Each support fixture 6 is detachably attached to the support member body 41. Each support fixture 6 attaches the support member 4 to the lifting beam 104 at a position where the support member body 41 intersects with the lifting beam 104.

[0062] Figure 12 is an enlarged side view showing the support fixtures 6 of Figure 2 attaching the support members 4 to the lifting beam 104. Figure 13 is an enlarged perspective view showing the support fixtures 6 of Figure 12. Each support fixture 6 has a support press member 61 and a holding structure 62. The holding structure 62 holds the support press member 61 on the support member 4.

[0063] 12, the support member 61 has a hook portion 611, a holding portion 612, and a connecting portion 613. The support member 61 has a Z-shape formed by the hook portion 611, the holding portion 612, and the connecting portion 613. The support member 61 is formed by bending a single raw material plate.

[0064] The support press member 61 is arranged with the hook portion 611 overlapping the underside of the upper flange of the lifting beam 104, which is an H-shaped steel. As a result, the hook portion 611 sandwiches a part of the lifting beam 104 between the support member 4. In other words, the support press member 61 is arranged with a part of the lifting beam 104 sandwiched between the support member 4 and the hook portion 611.

[0065] The holding portion 612 is disposed inside the support block 43. The holding portion 612 is held to the support block 43 by the holding structure 62. In this embodiment, the holding portion 612 is held by the base support block 43a.

[0066] The connecting portion 613 connects the hooking portion 611 arranged on the outside of the support block 43 with the holding portion 612 arranged on the inside of the support block 43. As a result, the connecting portion 613 extends from the hooking portion 611 through the open portion of the support block 43 to the holding portion 612.

[0067] The holding structure 62 includes a slide member 621 and a support fastening bolt 622 .

[0068] The slide member 621 is attached to the support member 4 so as to be slidable along the longitudinal direction of the support member 4. The cross-sectional shape of the slide member 621 in a plane perpendicular to the longitudinal direction of the support member 4 is C-shaped, as shown in Fig. 13. The slide member 621 is attached to the support member 4 with the support block 43 passing through the inside of the slide member 621.

[0069] 12, the support fastening bolt 622 is a support fastening member attached to the slide member 621. The threaded portion of the support fastening bolt 622 is screwed into a threaded hole provided in the slide member 621. The amount by which the support fastening bolt 622 is screwed into the slide member 621 is adjusted by turning the support fastening bolt 622. The holding portion 612 of the support presser member 61 is pressed against the support member 4 by the support fastening bolt 622, and is thereby held by the support member 4.

[0070] The support fastening bolt 622 is inserted from the slide member 621 through the opening of the support block 43 into the inside of the support block 43. The support fastening bolt 622 presses the holding portion 612 against the support member 4 inside the support block 43.

[0071] The holding portion 612 is an elastic portion that can be elastically deformed. As a result, the holding portion 612 functions as a leaf spring. The holding portion 612 is elastically deformed between the support fastening bolt 622 and the support member 4. The amount of elastic deformation of the holding portion 612 when pressed against the support member 4 is adjusted by adjusting the amount of threading of the support fastening bolt 622 into the slide member 621.

[0072] The support presser member 61 presses a portion of the lifting beam 104 against the support member 4 by the hooking portion 611 while the holding portion 612 is elastically deformed between the support fastening bolt 622 and the support member 4. As a result, a portion of the lifting beam 104 is gripped between the hooking portion 611 and the support member 4. The support member 4 is attached to the lifting beam 104 by gripping a portion of the lifting beam 104 between the hooking portion 611 and the support member 4. The gripping force when gripping a portion of the lifting beam 104 between the hooking portion 611 and the support member 4 can be adjusted by adjusting the amount of elastic deformation of the holding portion 612 when pressed against the support member 4.

[0073] As shown in Figure 2, each ruler attachment tool 7 is disposed at a position where the ruler member 5 intersects with the support member 4. Each ruler attachment tool 7 is detachably attached to the support member main body 41. Each ruler attachment tool 7 attaches the ruler member 5 to the support member 4 at a position where the ruler member 5 intersects with the support member 4.

[0074] Figure 14 is an enlarged perspective view showing the ruler fixture 7 of Figure 2. Each ruler fixture 7 has a support mounting structure 71, a ruler holding member 72, and a ruler connecting bolt 73.

[0075] The support mounting structure 71 is detachably attached to the support member 4. The support mounting structure 71 has a mounting member 711, a clamping plate 712, and a fastening bolt 713.

[0076] The mounting member 711 has a main body portion 711a that fits into the support member 4, and a pair of receiving plate portions 711b that protrude in opposite directions from the main body portion 711a. The mounting member 711 is attached to the support member 4 with the main body portion 711a fitted into the support member 4.

[0077] The sandwiching plate 712 is disposed inside the support block 43 of the support member 4. A screw hole is formed in the sandwiching plate 712. A fastening bolt 713 is threaded into the screw hole in the sandwiching plate 712, passing through a through hole provided in the main body portion 711a. When the main body portion 711a is fitted to the support member 4, a part of the support block 43 is gripped between the main body portion 711a and the sandwiching plate 712 by tightening the fastening bolt 713 into the screw hole in the sandwiching plate 712. With a part of the support block 43 gripped between the main body portion 711a and the sandwiching plate 712, the support mounting structure 71 is detachably attached to the support member 4.

[0078] The ruler connecting bolt 73 is a ruler connecting member that attaches the ruler holding member 72 to the support mounting structure 71. The ruler holding member 72 is fastened to the support mounting structure 71 by the ruler connecting bolt 73. In this embodiment, the ruler holding member 72 is detachably attached to the support mounting structure 71. In this embodiment, a thumbscrew is used as the ruler connecting bolt 73.

[0079] The ruler holding member 72 has an attachment plate portion 721 and a holding portion 722. The holding portion 722 is connected to the attachment plate portion 721. The ruler holding member 72 is formed by bending one raw material plate.

[0080] The mounting plate 721 is attached to one of the receiving plate portions 711b of the mounting member 711. A screw hole is provided in the mounting plate 721. A through hole is provided in each of the pair of receiving plate portions 711b as a through hole 711c. The ruler joining bolt 73 is passed through the through hole 711c of one of the receiving plate portions 711b and tightened into the screw hole of the mounting plate portion 721, thereby attaching the mounting plate portion 721 to one of the receiving plate portions 711b. In this way, the ruler holding member 72 is detachably attached to the support mounting structure 71.

[0081] The ruler holding member 72 is attached to the support mounting structure 71, and thereby the holding portion 722 holds the ruler member 5 against the support member 4. In this way, the ruler member 5 is attached to the support member 4.

[0082] Next, the procedure for placing the elevator installation template device 1 at the top of the hoistway 102 will be described. The installation template device 1 is placed at the top of the hoistway 102 by attaching it to multiple lift beams 104. When attaching the installation template device 1 to multiple lift beams 104, first, each support member 4 is prepared with its length adjusted to match the spacing between the multiple lift beams 104. The length of each support member 4 is adjusted by adjusting the number of extension support blocks 43b connected to the base support block 43a. Then, the support member 4 is placed on each lift beam 104 so that it spans the multiple lift beams 104. Then, each support member 4 is attached to each lift beam 104 using the support fixtures 6.

[0083] After this, each ruler member 5 is prepared with its length adjusted to match the size and installation position of the object to be positioned. In this embodiment, a hall threshold ruler member 5a with its length adjusted to match the size and installation position of the hall threshold, and a car rail ruler member 5b with its length adjusted to match the size and installation position of a pair of car guide rails are prepared. The length of each ruler member 5 is adjusted by adjusting the number of extension ruler blocks 54b connected to the base ruler block 54a.

[0084] Thereafter, each ruler member 5 is placed on each support member 4 so that it straddles multiple support members 4. Thereafter, each ruler member 5 is attached to each support member 4 using a ruler attachment 7. At this time, the position of each ruler member 5 in the horizontal direction is adjusted to match the positions of each object, i.e., the positions of the landing threshold and the pair of car guide rails.

[0085] Thereafter, the plumb lines 3 from which the weights 2 are suspended are respectively connected to the connectors 53 of the ruler members 5. As a result, the pair of plumb lines 3 connected to the respective connectors 53 of the platform threshold ruler members 5a are stretched vertically in the hoistway 102 as platform threshold plumb lines 3a. Similarly, the pair of plumb lines 3 connected to the respective connectors 53 of the car rail ruler members 5b are stretched vertically in the hoistway 102 as car rail plumb lines 3b. At this time, if it is necessary to adjust the distance between the pair of platform threshold plumb lines 3a, the position of the connector main body 532 relative to the protruding member 531 in the connector 53 of the platform threshold ruler members 5a is adjusted. Similarly, if it is necessary to adjust the distance between the pair of car rail plumb lines 3b, the position of the connector main body 532 relative to the protruding member 531 in the connector 53 of the car rail ruler members 5b is adjusted. In this manner, the installation template device 1 is positioned at the top of the hoistway 102.

[0086] In this elevator installation template device 1, the ruler member body 51 of each ruler member 5 has multiple ruler blocks 54. The multiple ruler blocks 54 are continuously and detachably connected to each other in the longitudinal direction of the ruler member 5. The length of the ruler member body 51 can be adjusted by adjusting the number of ruler blocks 54. In each ruler member 5, one connector 53 is attached to the ruler block 54 located at one end of the ruler member body 51, and the other connector 53 is attached to the ruler block 54 located at the other end of the ruler member body 51. This eliminates the need to overlap and slide the ruler blocks 54 together to adjust the length of the ruler member body 51. This eliminates overlapping portions between the ruler blocks 54 in the ruler member body 51. This reduces the weight of the ruler member body 51 and the ruler members 5. This makes the ruler members 5 easier to handle.

[0087] Furthermore, because the length of the ruler member 5 can be adjusted by adjusting the number of ruler blocks 54, a common installation template device 1 can be used, for example, when positioning an object when installing elevators of different types or sizes. This eliminates the need to prepare multiple different installation template devices for each type and size of elevator when installing an elevator. This reduces the burden of manufacturing management and inventory management of the installation template device 1.

[0088] The connector 52 of the ruler member 5 has a connector body 521, a first fastening bolt 522, and a second fastening bolt 523. The connector body 521 is disposed across the boundary between two adjacent ruler blocks 54. The first fastening bolt 522 fastens the connector body 521 to one of the ruler blocks 54. The second fastening bolt 523 fastens the connector body 521 to the other ruler block 54. This allows the two adjacent ruler blocks 54 to be more reliably connected. Furthermore, the two ruler blocks 54 can be positioned along the connector body 521 at the boundary between the two ruler blocks 54, preventing the ruler member 5 from bending at the boundary between the two ruler blocks 54. This more reliably maintains the ruler member 5 in a straight line.

[0089] Furthermore, in each connector 53, a connector body 532 to which the plumb line 3 is connected is detachably attached to a protruding member 531. A plurality of through holes are provided in the protruding member 531 as a plurality of adjustment holes 534, spaced apart from one another in the longitudinal direction of the ruler member 5. The connector body 532 is attached to the protruding member 531 while being selectively positioned in one of the plurality of adjustment holes 534. Therefore, by changing the adjustment hole 534 through which the connector body 532 passes, the position of the plumb line 3 connected to the ruler member 5 can be adjusted in the longitudinal direction of the ruler member 5. Therefore, by making the intervals between the plurality of adjustment holes 534 shorter than the dimensions of the ruler blocks 54, the position of the plumb line 3 can be adjusted more finely and easily than by adjusting the number of ruler blocks 54.

[0090] In the support mounting fixture 6, a holding structure 62 holds the support presser member 61 to the support member 4. The holding structure 62 has a slide member 621 slidably attached to the support member 4 and a support fastening bolt 622 attached to the slide member 621. The support fastening bolt 622 presses the holding portion 612 of the support presser member 61 against the support member 4, thereby holding the holding portion 612 to the support member 4. The support presser member 61 presses a portion of the lifting beam 104 against the support member 4 with the hook portion 611 while the holding portion 612 is elastically deformed between the support fastening bolt 622 and the support member 4. Therefore, the elastic restoring force of the holding portion 612 of the support presser member 61 allows a portion of the lifting beam 104 to be gripped between the hook portion 611 and the support member 4. This makes it possible to easily attach the support member 4 to the lifting beam 104. Moreover, since it is possible to avoid excessive force being applied to the lifting beam 104 and the support member 4, it is possible to prevent damage to the lifting beam 104 and the support member 4. Furthermore, it is possible to maintain a state in which the elastic restoring force of the holding portion 612 is applied to the support fastening bolt 622, which makes it possible to prevent the support fastening bolt 622 from loosening.

[0091] In addition, a fitting structure 58 is provided at the boundary between two adjacent ruler blocks 54. The fitting structure 58 has a protrusion 581 protruding from one ruler block 54 and a recess 582 formed in the other ruler block 54. The protrusion 581 fits into the recess 582. This makes it possible to prevent one ruler block 54 from shifting relative to the other ruler block 54 along the boundary between the two ruler blocks 54. This makes it possible to more reliably maintain the ruler member 5 in a straight line.

[0092] Furthermore, the fitting structure 58 is provided at the boundary between the back plate portions 541 of each of the two ruler blocks 54 and at the boundary between the side plate portions 542 of each of the two ruler blocks 54. Therefore, each fitting structure 58 can prevent each ruler block 54 from shifting in multiple directions along the boundary between the two ruler blocks 54. This makes it possible to more reliably maintain the ruler member 5 in a straight line.

[0093] Furthermore, the ruler attachment device 7 has a support attachment structure 71, a ruler holding member 72, and a ruler joining bolt 73. The support attachment structure 71 is detachably attached to the support member 4. The ruler holding member 72 holds the ruler member body 51 to the support member 4. The ruler joining bolt 73 attaches the ruler holding member 72 to the support attachment structure 71. This makes it possible to attach the ruler member 5 to the support member 4 easily and more reliably.

[0094] In the above embodiment, the number of support members 4 is two, and the number of ruler members 5 is two. However, the number of support members 4 may be three or more. The number of ruler members 5 may also be three or more, depending on the number of objects to be positioned.

[0095] Furthermore, in the above embodiment, in each of the pair of connectors 53 in each ruler member 5, a plurality of adjustment holes 534 are provided in the protruding member 531, making it possible to adjust the connection position of the plumb line 3 to the ruler member 5. However, it is also possible to make the connection position of the plumb line 3 to the ruler member 5 adjustable in only one of the pair of connectors 53. Also, in each of the pair of connectors 53, the connection position of the plumb line 3 to the ruler member 5 may be fixed so that it cannot be adjusted.

[0096] Furthermore, in the above embodiment, two adjacent ruler blocks 54 are connected by a connector 52. However, if the two ruler blocks 54 can be connected to each other without the connector 52, the connector 52 may be omitted. For example, a portion of each ruler block 54 may be a permanent magnet, and the two ruler blocks 54 may be connected to each other by the magnetic force of the permanent magnet.

[0097] Furthermore, in the above embodiment, a fitting structure 58 is provided at the boundary between two adjacent ruler blocks 54. However, the fitting structure 58 does not have to be provided. Even without the fitting structure 58, multiple ruler blocks 54 can be detachably connected to one another in succession in the ruler member 5, and the length of the ruler member main body 51 can be adjusted by adjusting the number of ruler blocks 54.

[0098] In the above embodiment, the support member 4 has a plurality of support blocks 43 connected in series. However, the configuration of the support member 4 is not limited to this. For example, a rod with no joints and whose length cannot be adjusted may be used as the support member 4.

[0099] Furthermore, in the above embodiment, the length of the base ruler block 54a is longer than the length of the extension ruler block 54b. However, the length of the base ruler block 54a may be the same as the length of the extension ruler block 54b, and the lengths of the multiple ruler blocks 54 in each ruler member 5 may all be the same. In this way, the lengths of the ruler blocks 54 can be unified, making it easier to manufacture the ruler blocks 54.

[0100] In the above embodiment, the extension ruler blocks 54b in the ruler member 5 all have the same length. However, the extension ruler blocks 54b in the ruler member 5 may have different lengths. In this way, by adjusting the combination of the lengths of the extension ruler blocks 54b, the length of the ruler member main body 51 can be adjusted more precisely.

[0101] 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.
