[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 58-87763 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional elevator disclosed in Patent Document 1, the U-shaped mounting bracket is a single member. This limits the options for the position of the rail bracket fixed to the mounting bracket. This can make it difficult to adjust the position of the rail bracket depending on the layout of the car, making it difficult to reduce the space in the elevator shaft.

[0005] The present disclosure is intended to solve the above-mentioned problems, and aims to provide an elevator rail mounting device and an elevator rail mounting method that can save space in the elevator shaft. [Means for solving the problem]

[0006] The elevator rail mounting device according to the present disclosure comprises a main body bracket, a main body anchor bolt fixed to the first wall surface of a first and second wall surfaces formed on the walls of a hoistway, a main body fixing device for fixing the main body bracket to the first wall surface, a support bracket fixed to the main body bracket, a support anchor bolt fixed to the second wall surface and a support fixing device for fixing the support bracket to the second wall surface, and a rail bracket fixed to the main body bracket and attached to a guide rail that guides the elevating body, wherein a plane including the first wall surface and a plane including the second wall surface intersect each other, and the main body bracket and the support bracket are separate members. [Effects of the Invention]

[0007] According to the present disclosure, it is possible to save space in the elevator shaft. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] 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.

[0010] Embodiment 1 FIG. 1 is a top view showing an elevator rail mounting device according to embodiment 1. FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1. FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1. FIG. 4 is a perspective view showing the elevator rail mounting device of FIG. 1. The walls of the hoistway 1 are formed with a front wall surface (not shown), a rear wall surface 11, a left wall surface 12, and a right wall surface (not shown). When viewed from above, the hoistway 1 is surrounded by the front wall surface, the rear wall surface 11, the left wall surface 12, and the right wall surface.

[0011] The left wall surface 12 and the right wall surface 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 the landing of each floor. The front wall surface and the rear wall surface 11 face each other in the depth direction of the hoistway 1. The depth direction of the hoistway 1 coincides with the horizontal direction perpendicular to the width direction of the hoistway 1.

[0012] At the landings on each floor, a landing entrance (not shown) that penetrates the front wall surface is formed in the wall of the elevator shaft 1. At each floor, the elevator shaft 1 is open to the landing through the landing entrance. Each landing entrance can be opened and closed by a landing door (not shown). In this embodiment, when the landing entrance is viewed from the landing on each floor, the wall surface located to the left of the landing entrance is the left wall surface 12, and the wall surface located to the right of the landing entrance is the right wall surface. Also, in this embodiment, when the landing entrance is viewed from the landing on each floor, the rear wall surface is located further back than the front wall surface.

[0013] The plane including the left wall surface 12 intersects with each of the two planes including the front wall surface and the rear wall surface 11, respectively. The plane including the right wall surface also intersects with each of the two planes including the front wall surface and the rear wall surface 11, respectively. In this embodiment, when the elevator shaft 1 is viewed from above, the left wall surface 12 and the right wall surface are each perpendicular to the front wall surface and the rear wall surface 11, respectively. As a result, in this embodiment, the shape of the elevator shaft 1 when viewed from above is rectangular with corners formed at each of the four corners.

[0014] As shown in Fig. 1, a car 13 and a counterweight 14 are provided in the hoistway 1 as a lifting body that can move up and down. In this embodiment, when the hoistway 1 is viewed from above, the counterweight 14 is located next to the car 13 in the width direction of the hoistway 1. The counterweight 14 is located closer to the left wall surface 12 than the car 13.

[0015] In the hoistway 1, a pair of car guide rails and a pair of counterweight guide rails 2 (not shown) are arranged in the vertical direction. Each car guide rail is a guide rail that guides a car 13. Each counterweight guide rail 2 is a guide rail that guides a counterweight 14. In this embodiment, the pair of car guide rails face each other in the width direction of the hoistway 1, with the car 13 interposed therebetween, and the pair of counterweight guide rails 2 face each other in the depth direction of the hoistway 1, with the counterweight 14 interposed therebetween. The configuration of the car guide rails is similar to the configuration of the counterweight guide rails 2.

[0016] Of the pair of counterweight guide rails 2 , one counterweight guide rail 2 located near the rear wall surface 11 is attached to the wall of the hoistway 1 via a rail attachment device 3 .

[0017] The counterweight guide rail 2 has a flange portion 21 and a guide portion 22. The flange portion 21 is a plate-shaped portion arranged along the vertical direction. The guide portion 22 is provided on the flange portion 21 along the longitudinal direction of the flange portion 21. When the counterweight guide rail 2 is viewed along the longitudinal direction of the counterweight guide rail 2, the guide portion 22 protrudes from the middle portion of the flange portion 21. This gives the counterweight guide rail 2 a T-shaped cross section. One of the counterweight guide rails 2 attached to the wall of the hoistway 1 by the rail mounting device 3 is arranged with the back surface of the flange portion 21 facing the rear wall surface 11.

[0018] The rail mounting device 3 is disposed at a corner formed between the rear wall surface 11 and the left wall surface 12 of the elevator shaft 1. The horizontal external force acting on the counterweight guide rail 2 is supported by the rear wall surface 11 and the left wall surface 12 via the rail mounting device 3.

[0019] The rail mounting device 3 has a main body bracket 4, a main body fixing device 5, a support bracket 6, a support fixing device 7, and a rail bracket 8. In this embodiment, the first wall surface to which the main body bracket 4 is fixed is the rear wall surface 11, and the second wall surface to which the support bracket 6 is fixed is the left wall surface 12. The main body bracket 4, the support bracket 6, and the rail bracket 8 are separate members.

[0020] Here, Fig. 5 is a perspective view showing the main body bracket 4 of Fig. 4. The main body bracket 4 has a main body base portion 41 and a main body protruding portion .

[0021] The main body base portion 41 is a plate-like portion arranged along the longitudinal direction of the main body bracket 4. The main body base portion 41 is provided with a main body fixing hole 43. The main body fixing hole 43 penetrates the main body base portion 41. In this embodiment, the main body bracket 4 has one main body fixing hole 43, which is a circular hole.

[0022] The main body protrusion 42 is a plate-like portion provided on the edge of the main body base portion 41. The main body protrusion 42 is arranged along the longitudinal direction of the main body bracket 4. When the main body bracket 4 is viewed along the longitudinal direction of the main body bracket 4, the main body protrusion 42 protrudes from the edge of the main body base portion 41 in a direction intersecting with the main body base portion 41. As a result, when the main body bracket 4 is viewed along the longitudinal direction of the main body bracket 4, the main body base portion 41 and the main body protrusion 42 form an L-shape.

[0023] As shown in Fig. 1, the main body bracket 4 is disposed in the space between the back surface of the counterweight guide rail 2 and the rear wall surface 11. As shown in Figs. 2 and 3, the main body bracket 4 is disposed with the main body base portion 41 overlapping the rear wall surface 11. The main body bracket 4 is also disposed with the main body protrusion portion 42 protruding from the top of the main body base portion 41 toward the opposite side of the rear wall surface 11.

[0024] The main body bracket 4 is arranged so that the longitudinal direction of the main body bracket 4 coincides with the horizontal direction along the rear wall surface 11. Therefore, in this embodiment, the longitudinal direction of the main body bracket 4 coincides with the width direction of the elevator shaft 1. Also, in this embodiment, the main body protrusion 42 is arranged horizontally.

[0025] The main body fixing device 5 fixes the main body bracket 4 to the rear wall surface 11. In this embodiment, there is one main body fixing device 5 that fixes the main body bracket 4 to the rear wall surface 11. The main body fixing device 5 has a main body anchor bolt 51 and a main body fixing nut 52.

[0026] The main body anchor bolts 51 are fixed to the rear wall surface 11 by being driven into pilot holes (not shown) provided in the wall on which the rear wall surface 11 is formed. The main body anchor bolts 51 are passed through main body fixing holes 43 provided in the main body base portion 41. The main body fixing device 5 fixes the main body bracket 4 to the rear wall surface 11 with the main body anchor bolts 51 passed through the main body fixing holes 43.

[0027] The main body fixing nut 52 is screwed into the main body anchor bolt 51. A part of the main body base portion 41 is sandwiched between the rear wall surface 11 and the main body fixing nut 52. The main body fixing device 5 fixes the main body bracket 4 to the rear wall surface 11 by tightening the main body fixing nut 52 and pressing the main body base portion 41 against the rear wall surface 11.

[0028] Fig. 6 is a perspective view showing the support bracket 6 of Fig. 4. The support bracket 6 has a support base portion 61 and a support extension portion 62.

[0029] The support base portion 61 is a plate-shaped portion arranged along the longitudinal direction of the support bracket 6. The support base portion 61 is provided with a support fixing hole 63. The support fixing hole 63 penetrates the support base portion 61. In this embodiment, the support bracket 6 has one support fixing hole 63, which is a circular hole.

[0030] The support overhang 62 is a plate-like portion provided on the edge of the support base portion 61. The support overhang 62 is arranged along the longitudinal direction of the support bracket 6. When the support bracket 6 is viewed along the longitudinal direction of the support bracket 6, the support overhang 62 protrudes from the edge of the support base portion 61 in a direction intersecting the support base portion 61. As a result, when the support bracket 6 is viewed along the longitudinal direction of the support bracket 6, the shape of the support bracket 6 is L-shaped due to the support base portion 61 and the support overhang 62.

[0031] As shown in Fig. 1, the support bracket 6 is disposed in the space between the counterweight guide rail 2 and the left wall surface 12. As shown in Figs. 2 and 3, the support bracket 6 is disposed with the support base portion 61 overlapping the left wall surface 12. The support bracket 6 is also disposed with the support protrusion portion 62 protruding from the upper portion of the support base portion 61 toward the opposite side of the left wall surface 12.

[0032] The support bracket 6 is arranged so that the longitudinal direction of the support bracket 6 coincides with the horizontal direction along the left wall surface 12. Therefore, in this embodiment, the longitudinal direction of the support bracket 6 coincides with the depth direction of the elevator shaft 1. Also, in this embodiment, the support overhang 62 is arranged horizontally.

[0033] The support fixture 7 fixes the support bracket 6 to the left wall surface 12. In this embodiment, there is one support fixture 7 that fixes the support bracket 6 to the left wall surface 12. The support fixture 7 has a support anchor bolt 71 and a support fixing nut 72.

[0034] The support anchor bolt 71 is fixed to the left wall surface 12 by being driven into a pilot hole (not shown) provided in the wall on which the left wall surface 12 is formed. The support anchor bolt 71 is passed through a support fixing hole 63 provided in the support base portion 61. The support fixing device 7 fixes the support bracket 6 to the left wall surface 12 with the support anchor bolt 71 passed through the support fixing hole 63.

[0035] The support fixing nut 72 is screwed onto the support anchor bolt 71. A portion of the support base portion 61 is sandwiched between the left wall surface 12 and the support fixing nut 72. The support fixture 7 fixes the support bracket 6 to the left wall surface 12 by tightening the support fixing nut 72 and pressing the support base portion 61 against the left wall surface 12.

[0036] A portion of the support overhang 62 overlaps with the main body overhang 42. In this embodiment, a portion of the support overhang 62 overlaps with the underside of the main body overhang 42. The support overhang 62 is fixed to the main body overhang 42 at the portion where it overlaps with the main body overhang 42. In this embodiment, the support overhang 62 is fixed to the main body overhang 42 by welding. In this way, the support bracket 6 is fixed to the main body bracket 4.

[0037] The rail bracket 8 is fixed to the main body bracket 4. The rail bracket 8 is attached to the counterweight guide rail 2 by a holder 10.

[0038] Fig. 7 is a perspective view showing the rail bracket 8 of Fig. 4. The rail bracket 8 has a fixed base portion 81 and a rail mounting portion 82. The fixed base portion 81 is a plate-shaped portion arranged along the longitudinal direction of the rail bracket 8.

[0039] The rail mounting portion 82 is a plate-like portion provided on the edge of the fixed base portion 81. The rail mounting portion 82 is arranged along the longitudinal direction of the rail bracket 8. When the rail bracket 8 is viewed along the longitudinal direction of the rail bracket 8, the rail mounting portion 82 protrudes from the edge of the fixed base portion 81 in a direction intersecting with the fixed base portion 81. As a result, when the rail bracket 8 is viewed along the longitudinal direction of the rail bracket 8, the shape of the rail bracket 8 is L-shaped due to the fixed base portion 81 and the rail mounting portion 82.

[0040] The rail mounting portion 82 is provided with a pair of rail mounting holes 83. Each rail mounting hole 83 penetrates the rail mounting portion 82. The pair of rail mounting holes 83 are spaced apart from each other in the longitudinal direction of the rail bracket 8. In this embodiment, the center position between the pair of rail mounting holes 83 in the longitudinal direction of the rail bracket 8 coincides with the center position between both end portions of the rail bracket 8 in the longitudinal direction of the rail bracket 8. Each rail mounting hole 83 is an elongated hole. The longitudinal direction of each rail mounting hole 83 coincides with the longitudinal direction of the rail bracket 8.

[0041] 3 and 4, the rail bracket 8 is arranged with a portion of the fixed base portion 81 overlapping the main body protrusion portion 42. As a result, the fixed base portion 81 is arranged horizontally. In this embodiment, a portion of the fixed base portion 81 overlaps the upper surface of the main body protrusion portion 42.

[0042] The rail bracket 8 is arranged with the rail mounting portion 82 positioned closer to the counterweight guide rail 2 than the fixed base portion 81. The rail bracket 8 is arranged with the rail mounting portion 82 protruding upward from the edge of the fixed base portion 81. The rail bracket 8 is arranged with the rail mounting portion 82 overlapping the back surface of the counterweight guide rail 2.

[0043] The fixed base portion 81 is fixed to the main body protrusion portion 42. In this embodiment, the fixed base portion 81 is fixed to the main body protrusion portion 42 by welding. In this way, the rail bracket 8 is fixed to the main body bracket 4.

[0044] The retainer 10 has a pair of rail clips 101 and a pair of fasteners 102. Each rail clip 101 is individually attached to the rail mounting portion 82 by a respective fastener 102. Each fastener 102 has a bolt passed through the rail mounting hole 83 and a nut screwed onto the bolt. The position of each fastener 102 relative to the rail mounting portion 82 is adjustable in the longitudinal direction of the rail bracket 8.

[0045] The flange portion 21 of the counterweight guide rail 2 is sandwiched between each rail clip 101 and the rail mounting portion 82. Each rail clip 101 presses the flange portion 21 of the counterweight guide rail 2 against the rail mounting portion 82 by the tightening force of each fastener 102. In this way, the holder 10 attaches the rail bracket 8 to the counterweight guide rail 2.

[0046] Next, a rail mounting method for mounting the counterweight guide rail 2 to the wall of the hoistway 1 using the rail mounting device 3 will be described. Figure 8 is a flowchart showing the elevator rail mounting method using the rail mounting device 3 of Figure 1. The rail mounting method includes a main body bracket fixing step S1, a support bracket fixing step S2, an inter-bracket fixing step S3, a rail mounting step S4, and a rail bracket fixing step S5. When mounting the counterweight guide rail 2 to the wall of the hoistway 1, first, the counterweight guide rail 2 is placed at a predetermined position in the hoistway 1. Thereafter, the main body bracket fixing step S1, the support bracket fixing step S2, the inter-bracket fixing step S3, the rail mounting step S4, and the rail bracket fixing step S5 are carried out in this order.

[0047] <Main body bracket fixing process S1> In the main body bracket fixing step S1, the main body bracket 4 is fixed to the rear wall surface 11 by the main body fixing tool 5.

[0048] In the main body bracket fixing process S1, the horizontal position of the main body bracket 4 relative to the counterweight guide rail 2 is adjusted based on the position of the counterweight guide rail 2. At this time, the position of the main body bracket 4 relative to the counterweight guide rail 2 is adjusted along the rear wall surface 11. As a result, the position of the main body fixing hole 43 is adjusted to a position offset from the position of the counterweight guide rail 2 in the width direction of the hoistway 1, as shown in FIG.

[0049] In the main body bracket fixing step S1, the position of the main body bracket 4 relative to the counterweight guide rail 2 is adjusted, and then the main body bracket 4 is fixed to the rear wall surface 11 by the main body fixing tool 5.

[0050] When fixing the main body bracket 4 to the rear wall surface 11 with the main body fastener 5, a pilot hole is drilled in the wall on which the rear wall surface 11 is formed using a drill tool. The position of the pilot hole drilled in the rear wall surface 11 is aligned with the position where the main body fixing hole 43 overlaps. Thereafter, the main body anchor bolt 51 is driven into the pilot hole in the rear wall surface 11 to fix the main body anchor bolt 51 to the rear wall surface 11. Thereafter, the main body anchor bolt 51 is inserted into the main body fixing hole 43 to overlap the main body base portion 41 of the main body bracket 4 with the rear wall surface 11. Thereafter, the main body fixing nut 52 is screwed onto the main body anchor bolt 51 and tightened to fix the main body bracket 4 to the rear wall surface 11.

[0051] <Support bracket fixing process S2> After the main body bracket fixing step S1, a support bracket fixing step S2 is performed. In the support bracket fixing step S2, the support bracket 6 is fixed to the left wall surface 12 by the support fixture 7.

[0052] In the support bracket fixing process S2, the position of the support bracket 6 relative to the main body bracket 4 is adjusted based on the position of the main body bracket 4. The adjustment of the position of the support bracket 6 relative to the main body bracket 4 is performed along the left wall surface 12 so that the support overhang portion 62 overlaps the main body overhang portion 42.

[0053] In the support bracket fixing step S2, the position of the support bracket 6 relative to the main body bracket 4 is adjusted, and then the support bracket 6 is fixed to the left wall surface 12 by the support fixture 7.

[0054] When fixing the support bracket 6 to the left wall surface 12 with the support fixing device 7, a pilot hole is drilled using a drill tool in the wall on which the left wall surface 12 is formed. The position of the pilot hole drilled in the left wall surface 12 is aligned with the position where the support fixing hole 63 overlaps. Thereafter, the support anchor bolt 71 is driven into the pilot hole in the left wall surface 12 to fix the support anchor bolt 71 to the left wall surface 12. Thereafter, the support anchor bolt 71 is inserted into the support fixing hole 63 to overlap the support base portion 61 of the support bracket 6 with the left wall surface 12. Thereafter, the support fixing nut 72 is screwed onto the support anchor bolt 71 and tightened to fix the support bracket 6 to the left wall surface 12.

[0055] <Inter-bracket fixing process S3> After the main body bracket fixing step S1 and the support bracket fixing step S2, an inter-bracket fixing step S3 is performed. In the inter-bracket fixing step S3, the support bracket 6 is fixed to the main body bracket 4.

[0056] In the inter-bracket fixing process S3, the support overhang portion 62 is fixed to the main body overhang portion 42 in a state where the support overhang portion 62 overlaps the main body overhang portion 42. In this embodiment, the support overhang portion 62 is fixed to the main body overhang portion 42 by welding. As a result, the support bracket 6 is integrated with the main body bracket 4.

[0057] <Rail installation process S4> After the inter-bracket fixing step S3, a rail mounting step S4 is carried out. In the rail mounting step S4, the rail bracket 8 is mounted on the counterweight guide rail 2.

[0058] In the rail mounting process S4, the rail mounting portion 82 is attached to the counterweight guide rail 2 by the holder 10 with the rail mounting portion 82 overlapping the back surface of the counterweight guide rail 2. In this embodiment, the rail bracket 8 is attached to the counterweight guide rail 2 in a state where the rail bracket 8 is not fixed to the main body bracket 4.

[0059] <Rail bracket fixing process S5> After the rail mounting step S4, a rail bracket fixing step S5 is carried out. In the rail bracket fixing step S5, the rail bracket 8 is fixed to the main body bracket 4.

[0060] In the rail bracket fixing process S5, the fixed base portion 81 of the rail bracket 8 is fixed by welding to the main body protrusion portion 42 of the main body bracket 4. In this way, the counterweight guide rail 2 is attached to the wall of the elevator shaft 1 by the rail mounting device 3.

[0061] In this rail mounting device 3, the main bracket 4 and the support bracket 6 are separate components. The first wall surface to which the main bracket 4 is fixed by the main fixture 5 is the rear wall surface 11. The second wall surface to which the support fixture 7 fixes the support bracket 6 is the left wall surface 12. The plane including the rear wall surface 11 and the plane including the left wall surface 12 intersect with each other. This allows the relative positions of the main bracket 4 and the support bracket 6 to be adjusted according to the layout of the car 13 and the counterweight 14, thereby increasing the degree of freedom in adjusting the positions of at least one of the main bracket 4 and the support bracket 6 relative to the rear wall surface 11 and the left wall surface 12. This allows, for example, the position of the support bracket 6 to be adjusted to a position that does not interfere with the counterweight 14, allowing the dimension of the counterweight 14 to be expanded in the direction approaching the left wall surface 12. This therefore contributes to space-saving in the hoistway 1.

[0062] Additionally, the support bracket 6 is fixed to the main body bracket 4. Therefore, the horizontal external force received by the counterweight guide rail 2 can be more reliably transmitted to each of the rear wall surface 11 and the left wall surface 12. This allows the rail mounting device 3 to stably support the counterweight guide rail 2.

[0063] Furthermore, in this rail mounting method, after the main body bracket fixing step S1 and the support bracket fixing step S2, an inter-bracket fixing step S3 is performed in which the support bracket 6 is fixed to the main body bracket 4. This eliminates the need to handle the main body bracket 4 and the support bracket 6 as a single unit, and the positional relationship between the main body bracket 4 and the support bracket 6 can be adjusted according to the layout of the car 13 and the counterweight 14. This makes it possible to adjust the position of the support bracket 6 to a position where it does not interfere with the counterweight 14, for example. This therefore allows for space savings in the hoistway 1.

[0064] Embodiment 2 Fig. 9 is a top view showing an elevator rail mounting device according to embodiment 2. Fig. 10 is a cross-sectional view taken along line XX in Fig. 9. Fig. 11 is a cross-sectional view taken along line XI-XI in Fig. 9. Fig. 12 is a perspective view showing the elevator rail mounting device of Fig. 9. The rail mounting device 3 has a connecting device 9 in addition to a main body bracket 4, a main body fixing device 5, a support bracket 6, a support fixing device 7, and a rail bracket 8.

[0065] Fig. 13 is a perspective view showing the main body bracket 4 of Fig. 12. The main body fixing hole 43 provided in the main body base portion 41 is an elongated hole. The longitudinal direction of the main body fixing hole 43 coincides with the longitudinal direction of the main body bracket 4.

[0066] A main body connecting hole 44 is provided in the main body protrusion 42 of the main body bracket 4. The main body connecting hole 44 penetrates the main body protrusion 42. In this embodiment, the main body connecting hole 44 is an elongated hole. The longitudinal direction of the main body connecting hole 44 coincides with a direction that intersects with the longitudinal direction of the main body fixing hole 43. In this embodiment, the longitudinal direction of the main body connecting hole 44 coincides with a direction that is perpendicular to the longitudinal direction of the main body fixing hole 43.

[0067] As shown in Figures 9 and 10, the main body bracket 4 is arranged with the longitudinal direction of the main body fixing holes 43 aligned with the horizontal direction along the rear wall surface 11. Therefore, when the main body bracket 4 is arranged with the main body base portion 41 overlapping the rear wall surface 11, the longitudinal direction of the main body fixing holes 43 is aligned with the width direction of the hoistway 1. As a result, the longitudinal direction of the main body connecting holes 44 is aligned with the horizontal direction intersecting the rear wall surface 11. In this embodiment, the longitudinal direction of the main body connecting holes 44 is aligned with the depth direction of the hoistway 1, as shown in Figure 9. Other configurations of the main body bracket 4 are the same as those in the first embodiment.

[0068] The main body fixing device 5 fixes the main body bracket 4 to the rear wall surface 11 with the main body anchor bolts 51 passing through the main body fixing holes 43. The horizontal position of the main body bracket 4 relative to the main body anchor bolts 51 is adjustable along the rear wall surface 11 within the range of the longitudinal dimension of the main body fixing holes 43. Therefore, the position of the main body bracket 4 is adjustable relative to the support bracket 6 in the longitudinal direction of the main body fixing holes 43, i.e., in the width direction of the hoistway 1.

[0069] 14 is a perspective view showing the support bracket 6 of FIG. 12. The support fixing hole 63 provided in the support base portion 61 is an elongated hole. The longitudinal direction of the support fixing hole 63 coincides with a direction intersecting the longitudinal direction of the support bracket 6. In this embodiment, the longitudinal direction of the support fixing hole 63 coincides with a direction perpendicular to the longitudinal direction of the support bracket 6.

[0070] A support connection hole 64 is provided in the support overhang portion 62 of the support bracket 6. The support connection hole 64 passes through the support overhang portion 62. The support connection hole 64 is a circular hole.

[0071] 11, the support bracket 6 is arranged with the longitudinal direction of the support fixing holes 63 aligned with the vertical direction. Therefore, when the support bracket 6 is arranged with the support base portion 61 overlapping the left wall surface 12, the longitudinal direction of the support fixing holes 63 is aligned with the vertical direction. Other configurations of the support bracket 6 are the same as those in the first embodiment.

[0072] The support fixture 7 fixes the support bracket 6 to the left wall surface 12 with the support anchor bolt 71 passing through the support fixing hole 63. The vertical position of the support bracket 6 relative to the support anchor bolt 71 is adjustable within the dimensional range of the longitudinal direction of the support fixing hole 63. Therefore, the position of the support bracket 6 is adjustable relative to the main bracket 4 in the longitudinal direction of the support fixing hole 63, i.e., in the vertical direction.

[0073] The support fixing device 7 prevents the support bracket 6 from moving in the depth direction of the hoistway 1 by engaging the support anchor bolt 71 with the support base portion 61. In other words, the support fixing device 7 supports the force in the depth direction of the hoistway 1 received from the support bracket 6 by a pressure-bearing joint.

[0074] In the rail mounting device 3, the position of the support bracket 6 is adjusted in the up-down direction relative to the main body bracket 4, so that a portion of the support overhang 62 overlaps the main body overhang 42, as shown in Figures 10 and 11 . Also, in the rail mounting device 3, the position of the main body bracket 4 is adjusted in the width direction of the hoistway 1 relative to the support bracket 6, so that the position of the main body connecting hole 44 overlaps the support connecting hole 64. In this embodiment, the main body connecting hole 44 is an elongated hole that extends along the depth direction of the hoistway 1, so that any misalignment of the position of the support connecting hole 64 relative to the main body connecting hole 44 is absorbed in the depth direction of the hoistway 1. In other words, the main body connecting hole 44 absorbs any misalignment of the position of the support connecting hole 64 relative to the main body connecting hole 44.

[0075] The connector 9 fixes the support bracket 6 to the main body bracket 4 while being passed through the main body connecting hole 44 and the support connecting hole 64. The connector 9 has a connecting bolt 91 and a connecting nut 92.

[0076] The connecting bolt 91 is passed through the main body connecting hole 44 and the support connecting hole 64. The connecting nut 92 is screwed onto the connecting bolt 91. The main body overhang portion 42 and the support overhang portion 62 are sandwiched between the head of the connecting bolt 91 and the connecting nut 92. When the connecting nut 92 is tightened with the main body overhang portion 42 and the support overhang portion 62 sandwiched between the head of the connecting bolt 91 and the connecting nut 92, the support overhang portion 62 is fixed to the main body overhang portion 42.

[0077] The connector 9 prevents movement of the main body bracket 4 in the width direction of the hoistway 1 relative to the support bracket 6 by engaging the main body protrusion 42 and the support protrusion 62 with the connecting bolt 91. This allows the connector 9 to transmit the force in the width direction of the hoistway 1 between the main body bracket 4 and the support bracket 6 by pressure-bearing connection. Other configurations in the second embodiment are the same as those in the first embodiment.

[0078] When the counterweight guide rail 2 is subjected to an external force in the horizontal direction, the external force received by the counterweight guide rail 2 is supported by the wall of the hoistway 1 via the rail mounting device 3. It is conceivable that the counterweight guide rail 2 may be subjected to external forces in three directions: a direction along the width of the hoistway 1 toward the left wall surface 12, a direction along the width of the hoistway 1 away from the left wall surface 12, and a direction along the depth of the hoistway 1 toward the rear wall surface 11.

[0079] Next, we will explain the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in the direction toward the left wall surface 12 along the width direction of the hoistway 1. FIG. 15 is a top view showing the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in the direction toward the left wall surface 12 along the width direction of the hoistway 1 in FIG. 9. When the counterweight guide rail 2 receives an external force F1 in the direction toward the left wall surface 12, the external force F1 is transmitted from the counterweight guide rail 2 to the rail bracket 8, the main body bracket 4, the connector 9, and the support bracket 6 in that order, and reaches the left wall surface 12. As a result, a pressing load acts on the left wall surface 12 from the support bracket 6. Therefore, the external force F1 in the direction toward the left wall surface 12 is supported by a reaction force F2 of the left wall surface 12 that opposes the pressing load of the support bracket 6.

[0080] 16 is a top view showing the forces supporting the moment acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force F1 acting in a direction toward the left wall surface 12 along the width direction of the hoistway 1 in FIG. 9. When the counterweight guide rail 2 receives the external force F1 in a direction toward the left wall surface 12, a force moment acts from the support bracket 6 to the left wall surface 12. When the force moment acts from the support bracket 6 to the left wall surface 12, the end of the support bracket 6 farther from the rear wall surface 11 is pressed against the left wall surface 12, and the end of the support bracket 6 closer to the rear wall surface 11 tries to move away from the left wall surface 12. In this case, the force moment acting on the left wall surface 12 is supported by a reaction force F3 of the left wall surface 12 that opposes the pressing load of the support bracket 6 and a holding force F4 of the left wall surface 12 that holds the support fixture 7.

[0081] Next, we will explain the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in the direction away from the left wall surface 12 along the width direction of the hoistway 1. FIG. 17 is a top view showing the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in the direction away from the left wall surface 12 along the width direction of the hoistway 1 in FIG. 9. When the counterweight guide rail 2 receives an external force F1 in the direction away from the left wall surface 12, the external force F1 is transmitted from the counterweight guide rail 2 to the rail bracket 8, the main body bracket 4, the connector 9, the support bracket 6, and the support fixture 7 in that order, before reaching the left wall surface 12. As a result, a load acts on the left wall surface 12 in a direction that pulls out the support fixture 7. Therefore, the external force F1 acting in a direction away from the left wall surface 12 is supported by the holding force F2 of the left wall surface 12 that holds the load in the direction in which the supporting fixture 7 is pulled out.

[0082] 18 is a top view showing the forces supporting the moment acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force F1 acting in a direction away from the left wall surface 12 along the width direction of the hoistway 1 in FIG. 9 . When the counterweight guide rail 2 receives the external force F1 in a direction away from the left wall surface 12, a moment of force acts from the support bracket 6 to the left wall surface 12. When the moment of force acts from the support bracket 6 to the left wall surface 12, the end of the support bracket 6 closer to the rear wall surface 11 is pressed against the left wall surface 12, and the end of the support bracket 6 farther from the rear wall surface 11 tries to move away from the left wall surface 12. In this case, the moment of force acting on the left wall surface 12 is supported by a reaction force F3 of the left wall surface 12 that opposes the pressing load of the support bracket 6 and a holding force F4 of the left wall surface 12 that holds the support fixture 7.

[0083] Next, we will explain the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in a direction toward the rear wall surface 11 along the depth direction of the hoistway 1. FIG. 19 is a top view showing the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in a direction toward the rear wall surface 11 along the depth direction of the hoistway 1 in FIG. 9. When the counterweight guide rail 2 receives an external force F1 in a direction toward the rear wall surface 11, the external force F1 is transmitted from the counterweight guide rail 2 to the rail bracket 8 and the main body bracket 4 in that order, and reaches the rear wall surface 11. As a result, a pressing load acts on the rear wall surface 11 from the main body bracket 4. Therefore, the external force F1 in the direction toward the rear wall surface 11 is supported by a reaction force F2 of the rear wall surface 11 that opposes the pressing load of the main body bracket 4.

[0084] Next, we will explain the rail mounting method for mounting the counterweight guide rail 2 to the wall of the hoistway 1 using the rail mounting device 3. In the rail mounting method, after placing the counterweight guide rail 2 in the hoistway 1, similar to the first embodiment, the main body bracket fixing process S1, the support bracket fixing process S2, the inter-bracket fixing process S3, the rail mounting process S4, and the rail bracket fixing process S5 are carried out in this order.

[0085] In this embodiment, in the support bracket fixing step S2, if the support overhang 62 is spaced apart in the vertical direction from the main body overhang 42, the position of the support bracket 6 relative to the main body bracket 4 is adjusted in the vertical direction. At this time, the position of the support bracket 6 relative to the support fixture 7 is adjusted along the longitudinal direction of the support fixing hole 63. Thereafter, the support bracket 6 is fixed to the left wall surface 12 by the support fixture 7.

[0086] Furthermore, in this embodiment, in the inter-bracket fixing step S3, if the position of the main body connecting hole 44 deviates in the width direction of the hoistway 1 from the position where it overlaps with the support connecting hole 64, the position of the main body bracket 4 relative to the support bracket 6 is adjusted in the width direction of the hoistway 1. When adjusting the position of the main body bracket 4 relative to the support bracket 6, the main body fixing nut 52 of the main body fastener 5 is loosened. In this way, the position of the main body connecting hole 44 is adjusted to a position where it overlaps with the support connecting hole 64.

[0087] In the inter-bracket fixing process S3, the positions of the main body connection holes 44 are adjusted to overlap the support connection holes 64, and then the support extension 62 of the support bracket 6 is fixed to the main body extension 42 of the main body bracket 4 with the connector 9. Other steps in the rail mounting method are the same as those in the first embodiment.

[0088] In this rail mounting device 3, the main body fixing holes 43 provided in the main body bracket 4 are elongated holes. The main body bracket 4 is arranged with the longitudinal direction of the main body fixing holes 43 aligned with the width direction of the hoistway 1, i.e., the horizontal direction along the rear wall surface 11. The main body fixing devices 5 fix the main body bracket 4 to the rear wall surface 11 with the main body anchor bolts 51 passing through the main body fixing holes 43. This allows the position of the main body bracket 4 relative to the main body fixing devices 5 to be adjusted along the main body fixing holes 43. As a result, even if the position of the main body bracket 4 relative to the support bracket 6 is misaligned in the horizontal direction along the rear wall surface 11, the position of the main body bracket 4 relative to the support bracket 6 can be adjusted. This makes it possible to easily fix the support bracket 6 to the main body bracket 4.

[0089] Furthermore, the support fixing holes 63 provided in the support bracket 6 are elongated holes. The support bracket 6 is arranged with the longitudinal direction of the support fixing holes 63 aligned with the vertical direction. The support fixture 7 fixes the support bracket 6 to the left wall surface 12 with the support anchor bolts 71 passed through the support fixing holes 63. Therefore, even if the support bracket 6 is separated from the main bracket 4 in the vertical direction, the position of the support bracket 6 relative to the main bracket 4 can be adjusted in the vertical direction. This makes it possible to easily fix the support bracket 6 to the main bracket 4.

[0090] Furthermore, the main body bracket 4 is provided with a main body connecting hole 44. The support bracket 6 is provided with a support connecting hole 64. The main body connecting hole 44 is an elongated hole. The longitudinal direction of the main body connecting hole 44 coincides with the horizontal direction intersecting the rear wall surface 11. The connector 9 is passed through the main body connecting hole 44 and the support connecting hole 64 to fix the support bracket 6 to the main body bracket 4. Therefore, the main body connecting hole 44 can be overlapped with the support connecting hole 64 within the dimensional range of the main body connecting hole 44 in the longitudinal direction. This makes it possible to absorb any misalignment of the support connecting hole 64 relative to the main body connecting hole 44, and ensure that the main body connecting hole 44 can be more reliably overlapped with the support connecting hole 64. Therefore, the connector 9 can be more reliably passed through the main body connecting hole 44 and the support connecting hole 64, and the support bracket 6 can be more reliably fixed to the main body bracket 4.

[0091] In the second embodiment, the main body connecting hole 44 is an elongated hole. However, the support connecting hole 64 may be an elongated hole and the main body connecting hole 44 may be a circular hole. In this case, the longitudinal direction of the support connecting hole 64 coincides with the horizontal direction intersecting the rear wall surface 11. Even in this case, the support connecting hole 64 can absorb any misalignment of the support connecting hole 64 relative to the main body connecting hole 44, and the main body connecting hole 44 can be more reliably aligned with the support connecting hole 64. In other words, by making either the main body connecting hole 44 or the support connecting hole 64 an elongated hole and aligning the longitudinal direction of that hole with the horizontal direction intersecting the rear wall surface 11, the main body connecting hole 44 can be more reliably aligned with the support connecting hole 64.

[0092] Embodiment 3 Fig. 20 is a top view showing an elevator rail mounting device according to embodiment 3. Fig. 21 is a cross-sectional view taken along line XXI-XXI in Fig. 20. Fig. 22 is a cross-sectional view taken along line XXII-XXII in Fig. 20. Fig. 23 is a perspective view showing the elevator rail mounting device of Fig. 20. As in embodiment 2, the rail mounting device 3 has a main body bracket 4, a main body fixing device 5, a support bracket 6, a support fixing device 7, a rail bracket 8, and a connecting device 9. In this embodiment, the first wall surface to which the main body bracket 4 is fixed is the left wall surface 12, and the second wall surface to which the support bracket 6 is fixed is the rear wall surface 11.

[0093] 24 is a perspective view showing the main body bracket 4 of FIG. 23. The main body fixing hole 43 provided in the main body base portion 41 is an elongated hole. The main body connecting hole 44 provided in the main body protruding portion 42 is also an elongated hole. The longitudinal direction of the main body fixing hole 43 coincides with the longitudinal direction of the main body bracket 4, and the longitudinal direction of the main body connecting hole 44 coincides with a direction intersecting the longitudinal direction of the main body fixing hole 43. In this embodiment, the longitudinal direction of the main body connecting hole 44 coincides with a direction perpendicular to the longitudinal direction of the main body fixing hole 43.

[0094] As shown in Fig. 20, the main body bracket 4 is disposed in the space between the counterweight guide rail 2 and the left wall surface 12. As shown in Figs. 21 and 22, the main body bracket 4 is disposed with the main body base portion 41 overlapping the left wall surface 12. The main body bracket 4 is also disposed with the main body protrusion portion 42 protruding from the upper portion of the main body base portion 41 toward the opposite side from the left wall surface 12.

[0095] As shown in Figures 21 and 22, the main body bracket 4 is arranged with the longitudinal direction of the main body fixing holes 43 aligned with the horizontal direction along the left wall surface 12. Therefore, when the main body bracket 4 is arranged with the main body base portion 41 overlapping the left wall surface 12, the longitudinal direction of the main body fixing holes 43 is aligned with the depth direction of the hoistway 1. As a result, the longitudinal direction of the main body connecting holes 44 is aligned with the horizontal direction intersecting the left wall surface 12. In this embodiment, the longitudinal direction of the main body connecting holes 44 is aligned with the width direction of the hoistway 1, as shown in Figure 20. Other configurations of the main body bracket 4 are the same as those in the second embodiment.

[0096] The main body fixing device 5 fixes the main body bracket 4 to the left wall surface 12 with the main body anchor bolt 51 passing through the main body fixing hole 43. The horizontal position of the main body bracket 4 relative to the main body anchor bolt 51 is adjustable along the left wall surface 12 within the range of the longitudinal dimension of the main body fixing hole 43. Therefore, the position of the main body bracket 4 is adjustable relative to the support bracket 6 in the longitudinal direction of the main body fixing hole 43, i.e., in the depth direction of the hoistway 1.

[0097] Figure 25 is a perspective view showing the support bracket 6 of Figure 23. The support fixing hole 63 provided in the support base portion 61 is an elongated hole. The longitudinal direction of the support fixing hole 63 coincides with a direction intersecting the longitudinal direction of the support bracket 6. In this embodiment, the longitudinal direction of the support fixing hole 63 coincides with a direction perpendicular to the longitudinal direction of the support bracket 6. The support connection hole 64 provided in the support overhang portion 62 is a round hole.

[0098] As shown in Figure 20, the support bracket 6 is disposed in the space between the back surface of the counterweight guide rail 2 and the rear wall surface 11. As shown in Figures 21 and 22, the support bracket 6 is disposed with the support base portion 61 overlapping the rear wall surface 11. The support bracket 6 is also disposed with the support protrusion portion 62 protruding from the upper portion of the support base portion 61 toward the opposite side of the rear wall surface 11. The support bracket 6 is disposed with the longitudinal direction of the support fixing holes 63 aligned with the up-down direction. Other configurations of the support bracket 6 are the same as those in the second embodiment.

[0099] The support fixture 7 fixes the support bracket 6 to the rear wall surface 11 with the support anchor bolt 71 passing through the support fixing hole 63. The vertical position of the support bracket 6 relative to the support anchor bolt 71 is adjustable within the range of the longitudinal dimension of the support fixing hole 63. Therefore, the position of the support bracket 6 is adjustable relative to the main bracket 4 in the longitudinal direction of the support fixing hole 63, i.e., in the vertical direction.

[0100] The support fixing device 7 prevents the support bracket 6 from moving in the width direction of the hoistway 1 by engaging the support anchor bolt 71 with the support base portion 61. In other words, the support fixing device 7 supports the force in the width direction of the hoistway 1 received from the support bracket 6 through a pressure-bearing joint.

[0101] In the rail mounting device 3, the position of the support bracket 6 is adjusted in the up-down direction relative to the main body bracket 4, so that a portion of the support overhang 62 overlaps with the main body overhang 42, as shown in Figures 21 and 22. Also, in the rail mounting device 3, the position of the main body bracket 4 is adjusted in the depth direction of the hoistway 1 relative to the support bracket 6, so that the position of the main body connecting hole 44 overlaps with the support connecting hole 64. In this embodiment, the main body connecting hole 44 is an elongated hole extending along the width direction of the hoistway 1, so that any misalignment in the position of the support connecting hole 64 relative to the main body connecting hole 44 is absorbed in the width direction of the hoistway 1. In other words, the main body connecting hole 44 absorbs any misalignment in the position of the support connecting hole 64 relative to the main body connecting hole 44.

[0102] The connecting device 9 prevents the movement of the main body bracket 4 in the depth direction of the hoistway 1 relative to the support bracket 6 by engaging the main body protrusion 42 and the support protrusion 62 with the connecting bolt 91. This allows the connecting device 9 to transmit force in the depth direction of the hoistway 1 between the main body bracket 4 and the support bracket 6 by pressure-bearing connection.

[0103] Figure 26 is a perspective view showing the rail bracket 8 of Figure 23. The center position between the pair of rail mounting holes 83 in the longitudinal direction of the rail bracket 8 is shifted from the center position between both ends of the rail bracket 8 in the longitudinal direction of the rail bracket 8.

[0104] As shown in Figures 20 to 23, the rail bracket 8 is arranged so that the longitudinal direction of the rail bracket 8 coincides with the width direction of the elevator shaft 1. Of both end portions of the rail bracket 8, the end farther from the pair of rail mounting holes 83 is fixed to the main body protrusion 42 of the main body bracket 4. In this embodiment, the fixed base portion 81 of the rail bracket 8 is fixed to the main body protrusion 42 by welding. Other configurations in the third embodiment are the same as those in the second embodiment.

[0105] Next, we will explain the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in a direction toward the left wall surface 12 along the width direction of the hoistway 1. FIG. 27 is a top view showing the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in a direction toward the left wall surface 12 along the width direction of the hoistway 1 in FIG. 20. When the counterweight guide rail 2 receives an external force F1 in a direction toward the left wall surface 12, the external force F1 is transmitted in this order to the rail bracket 8 and the main body bracket 4, and reaches the left wall surface 12. As a result, a pressing load is applied from the main body bracket 4 to the left wall surface 12. Therefore, the external force F1 in the direction toward the left wall surface 12 is supported by a reaction force F2 of the left wall surface 12 that opposes the pressing load of the main body bracket 4.

[0106] 28 is a top view showing the forces supporting the moment acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force F1 in a direction toward the left wall surface 12 along the width direction of the hoistway 1 in FIG. 20. When the counterweight guide rail 2 receives the external force F1 in a direction toward the left wall surface 12, a moment of force acts from the main body bracket 4 to the left wall surface 12. When the moment of force acts from the main body bracket 4 to the left wall surface 12, the end of the main body bracket 4 farther from the rear wall surface 11 is pressed against the left wall surface 12, and the end of the main body bracket 4 closer to the rear wall surface 11 tries to move away from the left wall surface 12. In this case, the moment of force acting on the left wall surface 12 is supported by a reaction force F3 of the left wall surface 12 that opposes the pressing load of the main body bracket 4 and a holding force F4 of the left wall surface 12 that holds the main body fastener 5.

[0107] Next, we will explain the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force acting in a direction away from the left wall surface 12 along the width direction of the hoistway 1. FIG. 29 is a top view showing the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force acting in a direction away from the left wall surface 12 along the width direction of the hoistway 1 in FIG. 20. When the counterweight guide rail 2 receives an external force F1 acting in a direction away from the left wall surface 12, the external force F1 is transmitted from the counterweight guide rail 2 to the rail bracket 8, the main body bracket 4, and the main body fixing device 5, in that order, and reaches the left wall surface 12. As a result, a load acts on the left wall surface 12 in a direction to pull out the main body fixing device 5. Therefore, the external force F1 acting in a direction away from the left wall surface 12 is supported by the holding force F2 of the left wall surface 12, which holds the load acting in the direction to pull out the main body fixing device 5.

[0108] 30 is a top view showing the forces supporting the moment acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force F1 acting in a direction away from the left wall surface 12 along the width direction of the hoistway 1 shown in FIG. 20. When the counterweight guide rail 2 receives the external force F1 in a direction away from the left wall surface 12, a moment of force acts from the main body bracket 4 to the left wall surface 12. When the moment of force acts from the main body bracket 4 to the left wall surface 12, the end of the main body bracket 4 closer to the rear wall surface 11 is pressed against the left wall surface 12, and the end of the main body bracket 4 farther from the rear wall surface 11 tries to move away from the left wall surface 12. In this case, the moment of force acting on the left wall surface 12 is supported by a reaction force F3 of the left wall surface 12 that opposes the pressing load of the main body bracket 4 and a holding force F4 of the left wall surface 12 that holds the main body fastener 5.

[0109] Next, we will explain the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in a direction toward the rear wall 11 along the depth direction of the hoistway 1. FIG. 31 is a top view showing the force that supports the load acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force in a direction toward the rear wall 11 along the depth direction of the hoistway 1 shown in FIG. 20. When the counterweight guide rail 2 receives an external force F1 in a direction toward the rear wall 11, the external force F1 is transmitted from the counterweight guide rail 2 to the rail bracket 8, the main body bracket 4, the connector 9, and the support bracket 6 in this order, and reaches the rear wall 11. As a result, a pressing load acts on the rear wall 11 from the support bracket 6. Therefore, the external force F1 in the direction toward the rear wall 11 is supported by a reaction force F2 of the rear wall 11 that opposes the pressing load of the support bracket 6.

[0110] 32 is a top view showing the forces supporting the moment acting on the wall of the hoistway 1 when the counterweight guide rail 2 receives an external force F1 in a direction toward the rear wall surface 11 along the depth direction of the hoistway 1 in FIG. 20. When the counterweight guide rail 2 receives the external force F1 in a direction toward the rear wall surface 11, a moment of force acts from the main body bracket 4 to the left wall surface 12. When the moment of force acts from the main body bracket 4 to the left wall surface 12, the end of the main body bracket 4 closer to the rear wall surface 11 is pressed against the left wall surface 12, and the end of the main body bracket 4 farther from the rear wall surface 11 tries to move away from the left wall surface 12. In this case, the moment of force acting on the left wall surface 12 is supported by a reaction force F3 of the left wall surface 12 that opposes the pressing load of the main body bracket 4 and a holding force F4 of the left wall surface 12 that holds the main body fastener 5.

[0111] Next, we will explain the rail mounting method for mounting the counterweight guide rail 2 to the wall of the hoistway 1 using the rail mounting device 3. In the rail mounting method, after placing the counterweight guide rail 2 in the hoistway 1, the steps of main body bracket fixing step S1, support bracket fixing step S2, inter-bracket fixing step S3, rail mounting step S4, and rail bracket fixing step S5 are carried out in this order, as in the second embodiment.

[0112] In this embodiment, the main body bracket 4 is fixed to the left wall surface 12 by the main body fastener 5 in the main body bracket fixing step S1.

[0113] In the present embodiment, in the support bracket fixing step S2, the support bracket 6 is fixed to the rear wall surface 11 by the support fixture 7. If the support extension 62 is spaced apart in the vertical direction from the main body extension 42 in the support bracket fixing step S2, the position of the support bracket 6 relative to the main body bracket 4 is adjusted in the vertical direction in the same manner as in the second embodiment.

[0114] In this embodiment, in the inter-bracket fixing step S3, if the position of the main body connection hole 44 deviates in the depth direction of the hoistway 1 from the position where it overlaps with the support connection hole 64, the position of the main body bracket 4 relative to the support bracket 6 is adjusted in the depth direction of the hoistway 1. When adjusting the position of the main body bracket 4 relative to the support bracket 6, the main body fixing nut 52 of the main body fastener 5 is loosened. In this way, the position of the main body connection hole 44 is adjusted to a position where it overlaps with the support connection hole 64. The other steps in the rail mounting method are the same as those in the second embodiment.

[0115] In this way, even if the first wall surface to which the main body bracket 4 is fixed is the left wall surface 12 and the second wall surface to which the support bracket 6 is fixed is the rear wall surface 11, the positional relationship between the main body bracket 4 and the support bracket 6 can be adjusted according to the layout of the car 13 and the counterweight 14, and the degree of freedom in adjusting the position of at least one of the main body bracket 4 and the support bracket 6 relative to the rear wall surface 11 and the left wall surface 12 can be increased. This makes it possible, for example, to adjust the position of the support bracket 6 to a position that does not interfere with the car 13, and to increase the dimensions of the car 13 in the direction approaching the rear wall surface 11. Therefore, space savings in the hoistway 1 can be achieved.

[0116] In the third embodiment, the main body connecting hole 44 is an elongated hole. However, the support connecting hole 64 may be an elongated hole and the main body connecting hole 44 may be a circular hole. In this case, the longitudinal direction of the support connecting hole 64 coincides with the horizontal direction intersecting the left wall surface 12. Even in this case, the support connecting hole 64 can absorb any misalignment of the support connecting hole 64 relative to the main body connecting hole 44, and the main body connecting hole 44 can be more reliably aligned with the support connecting hole 64. In other words, by making either the main body connecting hole 44 or the support connecting hole 64 an elongated hole and aligning the longitudinal direction of that hole with the horizontal direction intersecting the left wall surface 12, the main body connecting hole 44 can be more reliably aligned with the support connecting hole 64.

[0117] Furthermore, in the above-described second and third embodiments, the main body connecting hole 44 is an elongated hole. However, the main body connecting hole 44 and the support connecting hole 64 may each be a circular hole. Even in this case, the support bracket 6 can be fixed to the main body bracket 4 by positioning the main body connecting hole 44 so that it overlaps the support connecting hole 64 and passing the connecting tool 9 through the main body connecting hole 44 and the support connecting hole 64.

[0118] In addition, in each of the above embodiments, the number of body fasteners 5 for the body bracket 4 is one. However, the number of body fasteners 5 for the body bracket 4 may be multiple. In this case, the number of body fastening holes 43 in the body bracket 4 is the same as the number of body fasteners 5.

[0119] In addition, in each of the above embodiments, the number of support fixtures 7 for the support bracket 6 is one. However, the number of support fixtures 7 for the support bracket 6 may be multiple. In this case, the number of support fixing holes 63 in the support bracket 6 is the same as the number of support fixtures 7.

[0120] Furthermore, in each of the above-described embodiments, the rail mounting device 3 is disposed in a corner formed between the rear wall surface 11 and the left wall surface 12 in the hoistway 1. However, the position of the rail mounting device 3 is not limited to this. The rail mounting device 3 may be disposed in any of the corner formed between the front wall surface and the left wall surface 12, the corner formed between the rear wall surface 11 and the right wall surface, and the corner formed between the front wall surface and the right wall surface. In this case, the layouts of the car 13, counterweight 14, car guide rails, and counterweight guide rails 2 are adjusted.

[0121] In each of the above-described embodiments, the support bracket fixing step S2 is performed after the main body bracket fixing step S1 and before the inter-bracket fixing step S3. However, the main body bracket fixing step S1 may be performed after the support bracket fixing step S2 and before the inter-bracket fixing step S3.

[0122] In each of the above embodiments, the rail mounting step S4 is performed after the inter-bracket fixing step S3 and before the rail bracket fixing step S5. However, the rail mounting step S4 may be performed before any of the main body bracket fixing step S1, the support bracket fixing step S2, and the inter-bracket fixing step S3, or the rail mounting step S4 may be performed after the rail bracket fixing step S5.

[0123] In each of the above embodiments, the rail bracket fixing step S5 is performed after the rail mounting step S4. However, the rail bracket fixing step S5 may be performed before any of the main body bracket fixing step S1, the support bracket fixing step S2, the inter-bracket fixing step S3, and the rail mounting step S4.
