DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a side view showing an elevator according to embodiment 1. In Fig. 1, a machine room 2 is provided above a hoistway 1. In the machine room 2, a hoisting machine 3 and a deflector sheave 6 are installed.

[0011] The hoist 3 has a hoist body 4 and a drive sheave 5. The hoist body 4 has a hoist motor (not shown) and a hoist brake (not shown). The hoist motor rotates the drive sheave 5. The hoist brake keeps the drive sheave 5 stationary. The hoist brake also brakes the rotation of the drive sheave 5.

[0012] A suspension body 7 is wound around the drive sheave 5 and the deflector sheave 6. A plurality of ropes or a plurality of belts are used as the suspension body 7. A car 8 is connected to a first end of the suspension body 7 in the longitudinal direction. A counterweight 9 is connected to a second end of the suspension body 7 in the longitudinal direction.

[0013] The car 8 and the counterweight 9 are suspended in the hoistway 1 by a suspension 7. The car 8 and the counterweight 9 move up and down in the hoistway 1 by rotating the drive sheave 5.

[0014] A pair of car guide rail devices 10 and a pair of counterweight guide rail devices 11 are installed in the elevator shaft 1. In Fig. 1, only the car guide rail device 10 on one side and the counterweight guide rail device 11 on the other side are shown.

[0015] A pair of car guide rail devices 10 guide the lifting and lowering of the car 8. A pair of counterweight guide rail devices 11 guide the lifting and lowering of the counterweight 9.

[0016] The car 8 has a car frame 12 and a car chamber 13. The suspension body 7 is connected to the car frame 12. The car chamber 13 is supported by the car frame 12.

[0017] Fig. 2 is an enlarged front view showing a part of the car guide rail device 10 in Fig. 1. Fig. 3 is a side view showing the car guide rail device 10 in Fig. 2.

[0018] The car guide rail device 10 has a guide rail body 21, a batten 22, and a plurality of fasteners 23.

[0019] The guide rail main body 21 guides the ascent and descent of the car 8 as a lifting body. The guide rail main body 21 is fixed to the elevator shaft wall via a plurality of rail brackets (not shown).

[0020] Furthermore, the guide rail body 21 has a first rail member 31 and a second rail member 32. The first rail member 31 is joined to the upper end of the second rail member 32.

[0021] The batten 22 spans the joint between the first rail member 31 and the second rail member 32 and is fixed to the first rail member 31 and the second rail member 32. The batten 22 is also fixed to the guide rail body 21 by a plurality of fasteners 23. In Fig. 3, the plurality of fasteners 23 are omitted.

[0022] A combination of a bolt and a nut is used as each of the fasteners 23. A plurality of mounting holes (not shown) are provided in each of the first rail member 31 and the second rail member 32. Each of the fasteners 23 is passed through a corresponding mounting hole.

[0023] The first rail member 31 has a first blade surface 31a and a first back surface 31b. The first blade surface 31a is a surface facing the car 8. The first back surface 31b is a surface opposite to the first blade surface 31a, and is a surface facing the elevator shaft wall.

[0024] The second rail member 32 has a second blade surface 32a and a second back surface 32b. The second blade surface 32a is a surface facing the car 8. The second back surface 32b is a surface on the opposite side to the second blade surface 32a, and is a surface facing the hoistway wall.

[0025] A first inclined surface 31c is formed on the first back surface 31b. The first inclined surface 31c is inclined in the up-down direction with respect to the first blade surface 31a. The first inclined surface 31c is formed such that the distance between the first inclined surface 31c and the first blade surface 31a increases continuously upward from the joint between the first rail member 31 and the second rail member 32.

[0026] The distance between the first rear surface 31b and the first blade surface 31a at a position where the first inclined surface 31c is not formed is larger than the distance between the second blade surface 32a and the second rear surface 32b.

[0027] The batten 22 has a first overlapping surface 22a, a second overlapping surface 22b, and a batten back surface 22c. The first overlapping surface 22a is overlapped with the first inclined surface 31c. The second overlapping surface 22b is overlapped with the second back surface 32b. The batten back surface 22c is the surface opposite to the first overlapping surface 22a and the second overlapping surface 22b.

[0028] The first mating surface 22a is inclined with respect to the second mating surface 22b. When the second mating surface 22b is placed on the second rear surface 32b, the first mating surface 22a is parallel to the first inclined surface 31c.

[0029] The second overlapping surface 22b is parallel to the back surface 22c of the batten. Furthermore, when the batten 22 is fixed to the guide rail body 21, the back surface 22c of the batten is parallel to the first blade surface 31a and the second blade surface 32a. The first overlapping surface 22a is inclined with respect to the back surface 22c of the batten. That is, the first overlapping surface 22a of the first embodiment is formed so that the distance between the first overlapping surface 22a and the back surface 22c of the batten becomes continuously smaller toward the upper side.

[0030] Fig. 4 is a cross-sectional view taken along line IV-IV of the guide rail body 21 in Fig. 3. The guide rail body 21 has a bracket fixing portion 21a and a guide portion 21b. The bracket fixing portion 21a is a portion that is fixed to a rail bracket.

[0031] The guide portion 21b protrudes at a right angle from the center in the width direction of the bracket fixing portion 21a toward the car 8. The lifting and lowering of the car 8 is guided by the guide portion 21b.

[0032] The first blade surface 31a and the second blade surface 32a correspond to an end surface of the guide portion 21b opposite to the bracket fixing portion 21a. The first back surface 31b and the second back surface 32b correspond to an end surface of the bracket fixing portion 21a opposite to the guide portion 21b.

[0033] Fig. 5 is a front view showing the batten 22 of Fig. 3. A plurality of long holes 22d are provided in the batten 22. A corresponding fastener 23 is inserted into each of the long holes 22d.

[0034] The vertical dimension of each of the long holes 22d is greater than the horizontal dimension of each of the long holes 22d. This allows the position of the batten 22 relative to the guide rail body 21 to be adjusted in the vertical direction when all of the fasteners 23 are loosened.

[0035] Next, a method for installing the car guide rail device 10 will be described. After the second rail member 32 is installed in the elevator shaft 1, the first rail member 31 is temporarily installed on the second rail member 32. At this time, as shown in Fig. 6, a step is likely to occur between the first blade surface 31a and the second blade surface 32a.

[0036] From this state, the first blade surface 31a and the second blade surface 32a are aligned flush with each other using the jig 24 shown in Fig. 7. The jig 24 has a positioning plane 24a.

[0037] At this time, the first rail member 31 and the second rail member 32 are sandwiched between the jig 24 and the baffle plate 22, a force is applied to the baffle plate 22 in a direction approaching the jig 24, and the first blade surface 31a and the second blade surface 32a are placed against the positioning plane 24a.

[0038] At this time, the position of the batten 22 in the vertical direction is adjusted so that the first overlapping surface 22a is in close contact with the first inclined surface 31c.

[0039] Thereafter, the batten 22 is fixed to the guide rail body 21 by a plurality of fasteners 23.

[0040] Thus, the installation method of the car guide rail device 10 of the first embodiment has a first step and a second step. The first step is a step of bringing the first blade surface 31a and the second blade surface 32a into contact with the positioning plane 24a to make the first blade surface 31a and the second blade surface 32a flush with each other and adjusting the position of the batten 22 in the vertical direction. The second step is a step of fixing the batten 22 to the guide rail body 21 with a plurality of fasteners 23.

[0041] Fig. 8 is a side view illustrating a method for adjusting the position of the batten 22 in Fig. 3. The dimension of the lower end face of the first rail member 31 in a direction perpendicular to the first blade surface 31a is defined as a first dimension. The dimension of the upper end face of the second rail member 32 in a direction perpendicular to the second blade surface 32a is defined as a second dimension.

[0042] As shown by the solid line in FIG. 8, when the first dimension and the second dimension are equal, the boundary between first and second overlapping surfaces 22a and 22b is located at the joint between first and second rail members 31 and 32.

[0043] 8, when the first dimension is smaller than the second dimension, the batten 22 is shifted upward from the position indicated by the solid line. This allows the first overlapping surface 22a to be brought into close contact with the first inclined surface 31c while keeping the second overlapping surface 22b in close contact with the second back surface 32b. At this time, the boundary between the first overlapping surface 22a and the second overlapping surface 22b is located on the first inclined surface 31c indicated by the dotted line.

[0044] When the multiple fasteners 23 are loosened, the batten 22 can move up and down within the range of the gap dimension between each fastener 23 and the long hole 22d through which the fastener 23 passes.

[0045] In such a car guide rail device 10, a first inclined surface 31c is formed on the first back surface 31b. The batten 22 has a first overlapping surface 22a and a second overlapping surface 22b. The first overlapping surface 22a is inclined relative to the second overlapping surface 22b. When the second overlapping surface 22b is overlapped on the second back surface 32b, the first overlapping surface 22a is parallel to the first inclined surface 31c. When the multiple fasteners 23 are loosened, the position of the batten 22 relative to the guide rail body 21 can be adjusted in the vertical direction.

[0046] Therefore, even if a step occurs between the first inclined surface 31c and the second back surface 32b when the first blade surface 31a and the second blade surface 32a are aligned flush, the baffle plate 22 can be brought into close contact with the first inclined surface 31c and the second back surface 32b simply by adjusting the vertical position of the baffle plate 22.

[0047] Therefore, according to the car guide rail device 10 and the installation method thereof of the first embodiment, the centering work of the guide rail can be easily performed. Also, since there is no need to use shims, the number of parts can be reduced.

[0048] Embodiment 2 9 is a side view showing a main part of a car guide rail device 10 according to embodiment 2. In embodiment 2, the first inclined surface 31c is inclined with respect to the first blade surface 31a in the opposite direction to embodiment 1. That is, the first inclined surface 31c in embodiment 2 is formed such that the distance between the first inclined surface 31c and the first blade surface 31a continuously decreases upward from the joint between the first rail member 31 and the second rail member 32.

[0049] Accordingly, the first overlapping surface 22a is inclined with respect to the back surface 22c of the batten in the opposite direction to that in embodiment 1. That is, the first overlapping surface 22a in embodiment 2 is formed so that the distance between the first overlapping surface 22a and the back surface 22c of the batten increases continuously upward.

[0050] Other configurations in the second embodiment are similar to those in the first embodiment. In addition, the method of installing the car guide rail device 10 is also similar to that in the first embodiment.

[0051] With this configuration as well, the same effects as those of the first embodiment can be obtained.

[0052] In the first and second embodiments, first rail member 31, second rail member 32, and batten 22 may be arranged upside down relative to those in FIGS.

[0053] In addition, in embodiments 1 and 2, the distance between the first rear surface 31b and the first blade surface 31a at a position where the first inclined surface 31c is not formed may be the same as the distance between the second blade surface 32a and the second rear surface 32b.

[0054] Embodiment 3 Next, Fig. 10 is a side view showing a main part of the car guide rail device 10 according to the third embodiment. A second inclined surface 32c is formed on the second back surface 32b. The second inclined surface 32c is inclined in the up-down direction with respect to the second blade surface 32a. The second inclined surface 32c is formed such that the distance between the second inclined surface 32c and the second blade surface 32a increases continuously downward from the joint between the first rail member 31 and the second rail member 32.

[0055] The distance between the first back surface 31b and the first blade surface 31a at a position where the first inclined surface 31c is not formed is equal to the distance between the second back surface 32b and the second blade surface 32a at a position where the second inclined surface 32c is not formed.

[0056] The second overlapping surface 22b is inclined with respect to the batten back surface 22c. That is, the second overlapping surface 22b in the third embodiment is formed such that the distance between the second overlapping surface 22b and the batten back surface 22c becomes continuously smaller downward.

[0057] When the first mating surface 22a is mated with the first inclined surface 31c, the second mating surface 22b is parallel to the second inclined surface 31c.

[0058] The second overlapping surface 22b is symmetrical in the up-down direction to the first overlapping surface 22a, with the boundary between the first overlapping surface 22a and the second overlapping surface 22b as the center.

[0059] Other configurations in the third embodiment are similar to those in the first embodiment. In addition, the method of installing the car guide rail device 10 is also similar to that in the first embodiment.

[0060] Fig. 11 is a side view illustrating a method for adjusting the position of batten 22 in Fig. 10. As shown by a solid line in Fig. 11, when the first dimension and the second dimension are equal, the boundary between first overlapping surface 22a and second overlapping surface 22b is located at the joint between first rail member 31 and second rail member 32.

[0061] 11, when the first dimension is smaller than the second dimension, the batten 22 is shifted obliquely upward from the position of the solid line. This allows the first overlapping surface 22a to be brought into close contact with the first inclined surface 31c while the second overlapping surface 22b is kept in close contact with the second inclined surface 32c. At this time, the boundary between the first overlapping surface 22a and the second overlapping surface 22b is located on the first inclined surface 31c shown by the dotted line.

[0062] Although not shown, when the second dimension is smaller than the first dimension, the batten 22 is shifted diagonally downward from the position indicated by the solid line. This allows the second overlapping surface 22b to be brought into close contact with the second inclined surface 32c while keeping the first overlapping surface 22a in close contact with the first inclined surface 31c. At this time, the boundary between the first overlapping surface 22a and the second overlapping surface 22b is located on the second inclined surface 32c.

[0063] Even with this configuration, it is possible to obtain the same effects as in embodiment 1. Moreover, regardless of whether the first dimension or the second dimension is smaller, batten 22 can be easily brought into close contact with first rail member 31 and second rail member 32.

[0064] Embodiment 4 12 is a side view showing a main part of a car guide rail device 10 according to embodiment 4. In embodiment 4, the first inclined surface 31c is inclined with respect to the first blade surface 31a in the opposite direction to embodiment 3. That is, the first inclined surface 31c in embodiment 4 is formed such that the distance between the first inclined surface 31c and the first blade surface 31a continuously decreases upward from the joint between the first rail member 31 and the second rail member 32.

[0065] Accordingly, the first overlapping surface 22a is inclined with respect to the back surface 22c of the batten in the opposite direction to that in embodiment 3. That is, the first overlapping surface 22a in embodiment 4 is formed so that the distance between the first overlapping surface 22a and the back surface 22c of the batten increases continuously upward.

[0066] The second inclined surface 32c is inclined with respect to the second blade surface 32a in the opposite direction to that in embodiment 3. That is, the second inclined surface 32c in embodiment 4 is formed such that the distance between the second inclined surface 32c and the second blade surface 32a continuously decreases downward from the joint between the first rail member 31 and the second rail member 32.

[0067] Accordingly, the second overlapping surface 22b is inclined with respect to the back surface 22c of the batten in the opposite direction to that in embodiment 3. That is, the second overlapping surface 22b in embodiment 4 is formed so that the distance from the back surface 22c of the batten continuously increases downward.

[0068] Other configurations in the fourth embodiment are similar to those in the third embodiment. In addition, the method of installing the car guide rail device 10 is also similar to that in the third embodiment.

[0069] With this configuration as well, the same effects as those of the third embodiment can be obtained.

[0070] Embodiment 5. 13 is a side view showing a main part of the car guide rail device 10 according to the fifth embodiment. The first back surface 31b is parallel to the first blade surface 31a over the entire length of the first rail member 31. The second back surface 32b is parallel to the second blade surface 32a over the entire length of the second rail member 32. The distance between the first blade surface 31a and the first back surface 31b is smaller than the distance between the second blade surface 32a and the second back surface 32b.

[0071] The shape of the batten 22 is the same as that of the batten 22 in the first embodiment. A shim 25 is interposed between the first rail member 31 and the batten 22. The shim 25 has a shim front surface 25a and a shim back surface 25b. The shim front surface 25a is superimposed on the first back surface 31b. The first superimposing surface 22a is superimposed on the shim back surface 25b.

[0072] The shim back surface 25b is inclined in the up-down direction with respect to the shim front surface 25a. That is, the shim back surface 25b is formed such that the distance between the shim back surface 25b and the shim front surface 25a becomes continuously smaller downward.

[0073] When the second mating surface 22b is mated with the second back surface 32b, the first mating surface 22a is parallel to the shim back surface 25b.

[0074] As in the first embodiment, when all the fasteners 23 are loosened, the position of the batten 22 relative to the guide rail body 21 can be adjusted in the vertical direction.

[0075] Fig. 14 is a front view showing the shim 25 of Fig. 13. A plurality of round holes 25c are provided in the shim 25. A corresponding fastener 23 is inserted into each of the round holes 25c.

[0076] Other configurations in the embodiment 5 are similar to those in the embodiment 1. Moreover, except that the shim 25 is sandwiched between the first rail member 31 and the batten 22, the installation method of the car guide rail device 10 is also similar to that in the embodiment 1.

[0077] In such a cage guide rail device 10, even if a step occurs between the shim back surface 25b and the second back surface 32b when the first blade surface 31a and the second blade surface 32a are aligned flush, the baffle plate 22 can be brought into close contact with the shim back surface 25b and the second back surface 32b simply by adjusting the vertical position of the baffle plate 22.

[0078] Therefore, according to the car guide rail device 10 and the installation method thereof of the first embodiment, the centering operation of the guide rail can be facilitated. Also, it is not necessary to machine the first rail member 31 to have the first inclined surface 31c.

[0079] Embodiment 6 15 is a side view showing a main part of the car guide rail device 10 according to embodiment 6. The shape of the batten 22 is similar to that of the batten 22 in embodiment 2. The shim back surface 25b is formed so that the distance between the shim back surface 25b and the shim front surface 25a increases continuously downward.

[0080] Other configurations in the sixth embodiment are similar to those in the fifth embodiment. In addition, the method of installing the car guide rail device 10 is also similar to that in the fifth embodiment.

[0081] With this configuration as well, the same effects as those of the fifth embodiment can be obtained.

[0082] In the fifth and sixth embodiments, the distance between the first blade surface 31a and the first rear surface 31b may be the same as the distance between the second blade surface 32a and the second rear surface 32b.

[0083] Embodiment 7 Next, Fig. 16 is a side view showing a main part of the car guide rail device 10 according to the embodiment 7. Fig. 17 is a side view showing an enlarged view of the main part of Fig. 16.

[0084] A plurality of mounting surfaces are formed on the portion of the first rear surface 31b adjacent to the second rear surface 32b. In the seventh embodiment, the first rear surface 31b is formed with a first mounting surface 31d, a second mounting surface 31e, and a third mounting surface 31f. The distances between the first mounting surface 31d, the second mounting surface 31e, and the third mounting surface 31f and the first blade surface 31a gradually increase from the side closer to the second rail member 32 to the side farther from the second rail member 32.

[0085] The batten 22 of the seventh embodiment is a flat plate. That is, the second mating surface 22b is flush with the first mating surface 22a. The distance between the first mating surface 22a and the second mating surface 22b and the back surface 22c of the batten is uniform throughout the batten 22.

[0086] The batten 22 is superimposed on one of the multiple mounting surfaces and the second back surface 32b. In Fig. 16 and Fig. 17, the first superimposing surface 22a is superimposed on the third mounting surface 31f of the multiple mounting surfaces.

[0087] 16 and 17, the batten 22 is fixed to the guide rail body 21 by a plurality of fasteners 23. Although not shown, the first mounting surface 31d, the second mounting surface 31e, and the third mounting surface 31f each have a plurality of mounting holes formed therein.

[0088] Other configurations in the seventh embodiment are the same as those in the fifth embodiment. In addition, the method of installing the car guide rail device 10 is also the same as that in the fifth embodiment.

[0089] In such a car guide rail device 10, when the first blade surface 31a and the second blade surface 32a are aligned flush, the mesh panel 22 can be brought into close contact with either the first mounting surface 31d, the second mounting surface 31e, or the third mounting surface 31f and the second back surface 32b simply by adjusting the vertical position of the mesh panel 22.

[0090] Therefore, according to the car guide rail device 10 and the installation method thereof of the first embodiment, the centering work of the guide rail can be easily performed. Also, since there is no need to use shims, the number of parts can be reduced.

[0091] In the seventh embodiment, first rail member 31, second rail member 32, and batten 22 may be arranged upside down relative to that in FIG.

[0092] In the seventh embodiment, the number of mounting surfaces may be two or four or more.

[0093] In addition, in the first to seventh embodiments, the guide rail body 21 may be configured by joining three or more rail members together vertically.

[0094] The lifting body may be a counterweight 9. That is, the guide rail device may be a counterweight guide rail device 11.

[0095] Furthermore, in the first to seventh embodiments, the overall layout of the elevator is not limited to the layout in Fig. 1. For example, the roping system may be a 2:1 roping system.

[0096] The elevator may be a machine room-less elevator, a double deck elevator, a one-shaft multi-car elevator system, etc. The one-shaft multi-car system is a system in which an upper car and a lower car arranged directly below the upper car each independently ascend and descend in a common elevator shaft.
