Problems to be solved by the invention

The vibration isolator described in patent document 1 includes 3 rubber members facing the column. The 3 rubber members are fixed to the 1 plate member. Therefore, it is not possible to independently move the 3 rubber members by the plate member. For example, when the plate member is moved in a state where the rubber member 21 is in contact with the column to confirm that the rubber member 19 is in contact with the column, the rubber member 21 is moved in a state where it is in contact with the column. Due to the frictional resistance of the rubber member 21, the rubber member 19 may be determined to be in contact with the post even if the rubber member 19 is not in contact with the post.

The present invention has been made to solve the above problems. The invention aims to provide an elevator car provided with a vibration isolator which can independently move a plurality of components opposite to a column.

Means for solving the problems

The elevator car of the invention is provided with: a car room; a support device for supporting the car chamber; and a vibration-proof member provided in the car room. The support device is provided with: a lower member that supports the car room from below; and a column extending upward from the lower member. A No. 1 surface, a No. 2 surface and a No. 3 surface are formed on the column. The 1 st surface faces the car compartment side in a plan view. The 2 nd surface and the 3 rd surface face in opposite directions to each other. The vibration isolator is provided with: a 1 st cushioning member opposite the 1 st surface; a 1 st arm provided with a 1 st buffer member; a 2 nd buffer member opposite to the 2 nd surface; a 2 nd arm provided with a 2 nd buffer member; a 3 rd cushioning member opposite the 3 rd surface; a 3 rd arm provided with a 3 rd cushion member; a 1 st fixing means for fixing the 1 st arm and the 2 nd arm to an upper surface of the car room in a state where the 1 st arm and the 2 nd arm are overlapped; and a 2 nd fixing unit for fixing the 1 st arm and the 3 rd arm on the upper surface in a state that the 1 st arm and the 3 rd arm are overlapped.

Effects of the invention

The car of the elevator of the invention is provided with a vibration-proof piece. The vibration isolator is provided with: a 1 st cushioning member opposite the 1 st surface; a 1 st arm provided with a 1 st buffer member; a 2 nd buffer member opposite to the 2 nd surface; a 2 nd arm provided with a 2 nd buffer member; a 3 rd cushioning member opposite the 3 rd surface; a 3 rd arm provided with a 3 rd cushion member; 1 st fixing unit; and a 2 nd fixing unit. The 1 st fixing means fixes the 1 st arm and the 2 nd arm to the upper surface of the car room in a state where the 1 st arm and the 2 nd arm are overlapped. The 2 nd fixing unit fixes the 1 st arm and the 3 rd arm to the upper surface in a state that the 1 st arm and the 3 rd arm are overlapped. Therefore, if the elevator car is the elevator car of the present invention, the 1 st buffer member, the 2 nd buffer member and the 3 rd buffer member can be moved independently. That is, the position of the 1 st buffer member can be adjusted by the 1 st arm. The 2 nd arm can be used to adjust the position of the 2 nd cushioning member. The 3 rd arm can be used to adjust the position of the 3 rd cushioning member.

Detailed Description

Hereinafter, the detailed description will be given with reference to the drawings. Duplicate descriptions are appropriately simplified or omitted. In the drawings, the same reference numerals denote the same or equivalent portions.

Embodiment mode 1

Fig. 1 is a diagram showing an example of an elevator apparatus including a car 1 according to embodiment 1. The elevator apparatus includes a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in the hoistway 3 by the main ropes 4. The main ropes 4 are an example of means for suspending the car 1 and the counterweight 2 in the hoistway 3. The roping method for suspending the car 1 and the counterweight 2 is not limited to the example shown in fig. 1.

The main ropes 4 are wound around a drive sheave of the hoisting machine 5. The car 1 is driven by a hoisting machine 5. The control device 6 controls the hoisting machine 5. That is, the control device 6 controls the movement of the car 1. The car 1 and the control device 6 are connected by a control cable 7. The control device 6 controls the devices provided in the car 1 via the control cable 7.

Fig. 1 shows an example of a machine room 8 in which a hoisting machine 5 and a control device 6 are installed above a hoistway 3. The hoisting machine 5 and the control device 6 may be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed on the top of the hoistway 3 or may be installed in a pit.

Fig. 2 is a view schematically showing the car 1 as viewed from the direction a of fig. 1. The car 1 includes a car room 11, a frame 12, a vibration isolation member 13, a guide 14, and vibration isolation members 15 and 16. The cage 11 forms a space for passengers to ride. The frame 12 supports the car room 11. In the example shown in fig. 2, the frame 12 supports the car room 11 via the vibration isolation member 13. The frame 12 directly supports the car room 11 if the car 1 does not have the vibration isolation member 13. The frame 12 is an example of a device for supporting the car room 11. The means for supporting the car room 11 may not be frame-shaped. As shown in fig. 2, in the 1: in a rope-winding type elevator apparatus 1, a main rope 4 is connected to a frame 12.

The frame 12 shown in fig. 2 surrounds the car room 11 in the vertical and horizontal directions. The frame 12 has a lower member 21, a post 22, a post 23, and an upper member 24. The lower member 21 is disposed below the car room 11. The lower member 21 supports the car room 11 from below. The column 22 extends upward from one end of the lower member 21. The column 23 extends upward from the other end of the lower member 21. The cage 11 is disposed between the pillars 22 and 23. The upper end of the pillar 22 protrudes upward from the upper surface 11a of the car room 11. The upper end of the pillar 23 protrudes upward from the upper surface 11a of the cage 11. The upper member 24 is coupled to an upper end of the column 22 and an upper end of the column 23.

The guide 14 is provided to the frame 12. A pair of guide rails 9 are provided in the hoistway 3. The guide rail 9 extends vertically in the hoistway 3. The car 1 is disposed between the guide rails 9. The guides 14 disposed above and below the column 22 face the one guide rail 9. The guides 14 disposed above and below the column 23 face the other guide rail 9. The movement of the car 1 is guided by guide rails 9.

The vibration isolator 15 is provided in the car room 11. The vibration isolators 15 project from the car room 11 toward the pillars 22. The vibration isolator 16 is provided in the car room 11. The vibration isolators 16 project from the car room 11 toward the pillars 23. The vibration isolators 15 and 16 restrict displacement of the car room 11 in the horizontal direction with respect to the frame 12. This suppresses the inclination of the car room 11 with respect to the frame 12. Since the car 1 includes the vibration isolators 15 and 16, it is possible to prevent the car room 11 from contacting with surrounding equipment and generating noise, and to prevent the car room 11 and the equipment from being damaged. The mechanism of the vibration isolator 16 is the same as that of the vibration isolator 15. Therefore, the vibration isolator 15 will be described in detail below. The vibration isolator 16 will not be described in detail.

Fig. 3 is a view showing a section B-B of fig. 2. Fig. 4 is a view showing a section C-C of fig. 3. In fig. 4, the guide rail 9 is not shown. In the following, the X axis and the Y axis are set as shown in fig. 3. The X axis extends horizontally in the lateral width direction of the car 1. The Y axis extends horizontally in the depth direction of the car 1. The X-axis and the Y-axis are perpendicular to each other.

As shown in fig. 3, vertical surfaces 22a, 22b, and 22c are formed on the column 22 of the frame 12. The surface 22a faces in the X direction. That is, the surface 22a faces the car room 11 side in plan view. The surface 22b faces the Y direction. Surface 22c faces in the-Y direction. That is, the surface 22b and the surface 22c face in opposite directions to each other. In the example shown in fig. 3, surface 22a is perpendicular to surface 22 b. Surface 22a is perpendicular to surface 22c. The surface 22a is formed in such a manner as to join the surface 22b and the surface 22c.

Fig. 5 is a plan view showing the vibration preventing member 15. Fig. 6 is a front view of the vibration isolator 15 shown in fig. 5. Fig. 7 is a view showing a D-D section of fig. 5. The vibration isolator 15 includes shock absorbing members 31 to 33, arms 34 to 36, a lower pad 37, nuts 38 to 39, an upper pad 40, and bolts 41 to 42.

The buffer member 31 is a columnar member made of rubber, for example. Cushioning member 31 opposes surface 22a of post 22. Cushioning member 31 may also be in contact with surface 22 a. The buffer member 31 is provided to the arm 34. Fig. 8 is a plan view showing the arm 34. Fig. 9 is a front view showing the arm 34. Fig. 10 is a side view showing the arm 34. The arm 34 includes, for example, a plate member 45, a plate member 46, and a reinforcement 47.

The plate member 45 and the plate member 46 are formed by bending a flat plate at right angles. The plate member 45 is perpendicular to the X-axis. The plate member 45 is disposed opposite to the surface 22a of the column 22. The plate member 45 has a screw hole 45a. The plate member 46 extends from the lower end of the plate member 45 toward the car room 11, i.e., in the X direction. The width of the plate member 46 in the Y direction increases as it goes away from the plate member 45. The plate member 46 is placed on a member forming the upper surface 11a of the cage 11. In the following, the member forming the upper surface 11a of the car room 11 is also referred to as a ceiling member 25. The reinforcing member 47 is perpendicular to both the plate member 45 and the plate member 46. The reinforcement 47 is fixed to the plate member 45 and the plate member 46. Further, the arm 34 may not include the reinforcement 47.

Fig. 11 is a diagram showing an example of fixing the buffer member 31. The cushioning member 31 is provided to the plate member 45. Fig. 11 shows an example in which a spacer 52 is disposed between the cushioning member 31 and the plate member 45. The cushioning member 31 may be provided directly on the plate member 45. In the example shown in fig. 11, the bolt 53 penetrates the cushioning member 31 and the spacer 52. The cushioning member 31 is fixed to the surface 45b of the plate member 45 by screwing the bolts 53 passed through the cushioning member 31 and the spacer 52 into the screw holes 45a. Surface 45b faces the-X direction.

The plate member 46 has a pair of through holes 46a and a pair of through holes 46b. The width of the through hole 46a in the X direction is larger than the width in the Y direction. Similarly, the width of the through hole 46b in the X direction is larger than the width in the Y direction. The through holes 46a and 46b are aligned in a row in the Y direction.

The buffer member 32 is, for example, a cylindrical member made of rubber. Cushioning member 32 is opposite surface 22b of post 22. Cushioning member 32 may also be in contact with surface 22 b. The buffer member 32 is provided to the arm 35. Fig. 12 is a plan view showing the arm 35. Fig. 13 is a front view showing the arm 35. Fig. 14 is a side view showing the arm 35. The arm 35 includes, for example, a plate member 48 and a plate member 49.

The plate members 48 and 49 are formed by bending a flat plate at right angles. The plate member 48 is perpendicular to the Y-axis. The plate member 48 is disposed at least partially opposite the surface 22b of the post 22. The plate member 48 has a screw hole 48a. The plate member 49 extends from the lower end of the plate member 48 toward the arm 36 and the car room 11, i.e., in the-Y direction and the X direction. This can efficiently ensure the strength required for the arm 35 against the load received by the shock-absorbing member 32. The plate member 49 is placed on the plate member 46 of the arm 34. The arm 35 may be provided with a reinforcement perpendicular to the plate members 48 and 49.

Fig. 15 is a view showing a fixing example of the buffer member 32. The buffer member 32 is provided to the plate member 48. Fig. 15 shows an example in which a spacer 54 is arranged between the cushioning member 32 and the plate member 48, as in the example shown in fig. 11. The cushioning member 32 may be provided directly to the plate member 48. In the example shown in fig. 15, the bolt 55 penetrates the buffer member 32 and the spacer 54. The cushioning member 32 is fixed to the surface 48b of the plate member 48 by screwing the bolts 55, which have passed through the cushioning member 32 and the spacer 54, into the screw holes 48a. Surface 48b faces in the-Y direction.

The plate member 49 has a pair of through holes 49a. The width of the through hole 49a in the Y direction is larger than the width in the X direction. The through holes 49a are aligned in the Y direction.

The buffer member 33 is, for example, a columnar member made of rubber. Cushioning member 33 opposes surface 22c of post 22. Cushioning member 33 may also be in contact with surface 22c. The buffer member 33 is provided to the arm 36. Fig. 16 is a plan view showing the arm 36. The arm 35 and the arm 36 are symmetrical about the X-axis. The arm 36 includes, for example, a plate member 50 and a plate member 51.

The plate member 50 and the plate member 51 are formed by bending a flat plate at right angles. The plate member 50 is perpendicular to the Y-axis. The plate member 50 is disposed at least partially opposite the surface 22c of the post 22. The plate member 50 is formed with a screw hole 50a. The plate member 51 extends from the lower end of the plate member 50 toward the arm 35 and the car room 11, i.e., in the Y direction and the X direction. This can efficiently ensure the strength required for the arm 36 against the load received by the shock-absorbing member 33. The plate member 51 is placed on the plate member 46 of the arm 34. In addition, the plate member 49 and the plate member 51 do not overlap. The arm 36 may be provided with a reinforcement perpendicular to both the plate member 50 and the plate member 51.

The cushioning member 33 is provided on the plate member 50 in the same manner as the example shown in fig. 15. For example, the spacer 56 is disposed between the cushioning member 33 and the plate member 50. The cushioning member 33 may be directly provided to the plate member 50. When the spacer 56 is provided, the bolt 57 penetrates the cushioning member 33 and the spacer 56. The cushioning member 33 is fixed to the surface 50b of the plate member 50 by screwing the bolt 57 passed through the cushioning member 33 and the spacer 56 into the screw hole 50a. The surface 50b faces in the Y direction. Surface 48b and surface 50b are opposite each other.

The plate member 51 has a pair of through holes 51a. The width of the through hole 51a in the Y direction is larger than the width in the X direction. The through holes 51a are aligned in the Y direction.

Fig. 17 is a plan view showing the fixed assembly. Fig. 18 is a front view showing the fixed assembly. The fixed assembly is a member in which the lower bolster 37, the pair of nuts 38, and the pair of nuts 39 are integrated.

The lower pad 37 is a flat plate having a certain width. The lower pad 37 has a surface 37a and a surface 37b facing opposite directions to each other. The lower pad 37 is formed with a pair of through holes 37c and a pair of through holes 37d. The through holes 37c and 37d are aligned in a row in the Y direction. The nut 38 is fixed to the surface 37b by, for example, welding, in correspondence with the position of the through hole 37 c. The center of the nut 38 coincides with the center of the through hole 37 c. The nut 39 is fixed to the surface 37b by, for example, welding, in correspondence with the position of the through hole 37d. The center of the nut 39 coincides with the center of the through hole 37d. The nuts 38 and 39 are aligned in the Y direction. The lower mat 37 abuts against the ceiling member 25 from below such that the surface 37a faces the lower surface of the ceiling member 25. In addition, the functions of the nuts 38 and 39 may be realized by forming screw holes in the lower back plate 37.

In the example shown in the present embodiment, the upper mat 40 is a flat plate having the same shape as the lower mat 37. In addition, the shape of the upper pad 40 is not limited to the same shape as the lower pad 37. Fig. 19 is a plan view showing the upper mat 40. The upper pad 40 has a pair of through holes 40a and a pair of through holes 40b. The through holes 40a and 40b are aligned in a row in the Y direction. The upper pad 40 is placed on the plate member 49 of the arm 35 and the plate member 51 of the arm 36.

The bolt 41 and the nut 38 are an example of means for fixing the arm 34 and the arm 35 to the upper surface 11a of the car room 11 in a state where the plate member 46 of the arm 34 and the plate member 49 of the arm 35 are overlapped. The through-hole 40a, the through-hole 49a, the through-hole 46a, and the through-hole 37c are vertically arranged. The bolt 41 penetrates the upper mat 40, the arm 35, the arm 34, the ceiling member 25, and the lower mat 37 from above. The bolt 41 is screwed into the nut 38 below the lower back plate 37. Thus, the plate member 49 of the arm 35 is fixed to the upper surface 11a of the car room 11 together with the plate member 46 of the arm 34 by the bolt 41.

The bolt 42 and the nut 39 are an example of means for fixing the arm 34 and the arm 36 to the upper surface 11a of the car room 11 in a state where the plate member 46 of the arm 34 and the plate member 51 of the arm 36 are overlapped. The through hole 40b, the through hole 51a, the through hole 46b, and the through hole 37d are vertically arranged. The bolt 42 penetrates the upper mat 40, the arm 36, the arm 34, the ceiling material 25, and the lower mat 37 from above. The bolt 42 is screwed into the nut 39 below the lower shim plate 37. Thus, the plate member 51 of the arm 36 is fixed to the upper surface 11a of the car room 11 together with the plate member 46 of the arm 34 by the bolt 42.

In the example shown in the present embodiment, the buffer member 31, the buffer member 32, and the buffer member 33 can be moved independently. Specifically, the position of the buffer member 31 can be adjusted by the arm 34. The position of the cushioning member 32 can be adjusted by the arm 35. The position of the buffer member 33 can be adjusted by the arm 36. Therefore, even in a state where the buffer members 32 and 33 are in contact with the column 22, the contact of the buffer member 31 with the column 22 can be easily confirmed by the movement of the arm 34, that is, the pushing in of the arm 34 in the X direction.

Further, depending on the thickness of the wall of the car room 11, it may be necessary to adjust the position of the buffer member 31 in the X direction. Since a certain gap is required between the car room 11 and the pillar 22, if the wall thickness of the car room 11 becomes thick, the distance from the mounting position of the bolts 41 and 42 to the surface 22a of the pillar 22 becomes long. In the example shown in the present embodiment, the buffer member 31 can be arranged at a desired position corresponding to the distance by finely adjusting the position of the arm 34 along the X-axis. In addition, in order to adjust the position of the buffer member 31 in the X direction, a plurality of spacers 52 may be used.

In the example shown in the present embodiment, as shown in fig. 5, the plate member 46 of the arm 34 is disposed between the planes P1 and P2. That is, the plate member 46 does not protrude from the plane P1 in the Y direction. The plate member 46 does not protrude from the plane P2 in the-Y direction. The plane P1 is a plane including the surface 48b of the plate member 48. The plane P2 is a plane including the surface 50b of the plate member 50. More preferably, the entire arm 34 and the cushion member 31 are disposed between the planes P1 and P2. Therefore, the vibration isolator 15 can be downsized. In the example shown in the present embodiment, the height of the vibration isolator 15 and the area occupied in the plan view can be suppressed, and the cushioning members 31, 32, and 33 can be independently adjusted.

In the example shown in the present embodiment, a gap is formed between the plate member 45 provided with the cushioning member 31 and the plate member 48 provided with the cushioning member 32. Therefore, when the maintenance worker attaches the vibration isolators 15 to the ceiling member 25, the maintenance worker can confirm the state of the buffer member 31 and the state of the buffer member 32 from the gap by visual or manual touch. That is, the maintenance worker does not need to look into the vibration insulator 15 from above the probe in order to check the state of the cushion member 31 and the state of the cushion member 32. Even in the case where the upper member 24 is disposed directly above the vibration isolator 15 as in the example shown in fig. 4, the state of the cushion member 31 and the state of the cushion member 32 can be checked from the front side.

Similarly, in the example shown in the present embodiment, a gap is formed between the plate member 45 provided with the cushioning member 31 and the plate member 50 provided with the cushioning member 33. Therefore, when the maintenance worker attaches the vibration isolator 15 to the ceiling member 25, the maintenance worker can confirm the state of the cushion member 31 and the state of the cushion member 32 from the gap by visual observation or by hand touch. That is, the maintenance worker does not need to look into the vibration insulator 15 from above the probe in order to check the state of the cushion member 31 and the state of the cushion member 32. Even when the upper member 24 is disposed directly above the vibration isolator 15, the state of the cushion member 31 and the state of the cushion member 32 can be checked from the front side.

In the present embodiment, as shown in fig. 3, an example in which the cushioning material 31 faces the center portion of the front surface 22a of the column 22 when viewed from above is described. The cushioning material 31 may be disposed closer to the cushioning material 32 than to the cushioning material 33. In this case, the gap formed between the plate member 45 and the plate member 50 can be increased, and the state of the cushioning member 31 can be confirmed more easily. Similarly, the buffer member 31 may be disposed closer to the buffer member 33 than to the buffer member 32. In this case, the gap formed between the plate member 45 and the plate member 48 can be increased, and the state of the cushioning material 31 can be confirmed more easily.

In the present embodiment, an example in which the plate member 49 of the arm 35 and the plate member 51 of the arm 36 are placed on the plate member 46 of the arm 34 is described. The plate member 46 of the arm 34 may be placed on the plate member 49 of the arm 35 and the plate member 51 of the arm 36. In this case, the plate member 46 may be rectangular. This makes it possible to easily manufacture the arm 34.

Fig. 20 is a plan view showing another example of the car 1. Fig. 20 shows an example in which optional equipment such as air conditioning equipment is provided above the car room 11. When optional equipment is placed on the car room 11, the upper member 24 of the frame 12 needs to be disposed so as not to interfere with the optional equipment. That is, when the optional equipment is provided in the car 1, the upper member 24 is often disposed at a higher position than when the car 1 does not have the optional equipment. Fig. 20 (a) shows an example in which the upper member 24 is a square ring shape in a plan view. Fig. 20 (b) shows an example in which some of the members constituting the upper member 24 parallel to the X axis are disposed directly above the vibration insulators 15 and 16.

Fig. 21 is a view corresponding to fig. 3 of the car 1 shown in fig. 20. Fig. 22 is a view corresponding to fig. 4 of the car 1 shown in fig. 20. In the example shown in fig. 3 and 4, the vibration isolator 15 faces a coupling member 26 for coupling to the upper member 24 in the column 22. That is, the surfaces 22a to 22c are surfaces of the connecting member 26.

On the other hand, in the example shown in fig. 21 and 22, the vibration isolator 15 faces the column member 27 extending downward from the connecting member 26 in the column 22. That is, the surfaces 22a to 22c are the surfaces of the pillar members 27. The column member 27 is slightly thinner than the connecting member 26. Therefore, in the example shown in fig. 21 and 22, compared with the example shown in fig. 3 and 4, it is necessary to move the buffer member 31 in the-X direction, the buffer member 32 in the-Y direction, and the buffer member 33 in the Y direction. Such position adjustment can be easily performed if the example is the one described in the present embodiment.

Fig. 23 is a plan view showing another example of the vibration isolator 15. In the example shown in fig. 23, the vibration isolator 15 includes a support device 43 in addition to the shock absorbing members 31 to 33, the arms 34 to 36, the lower pad 37 (not shown), the nuts 38 to 39 (not shown), and the bolts 41 to 42. In the example shown in fig. 23, the upper pad 40 is not shown, but the vibration isolator 15 may be provided with a pad similar to the upper pad 40. By providing the same pad as the upper pad 40, the force of the holding arms 35 and 36 can be increased.

In the example shown in fig. 23, the arm 34 includes a plate member 58 in addition to the plate member 45, the plate member 46, and the reinforcing member 47. The plate member 58 is perpendicular to the X-axis. That is, the plate member 58 is disposed parallel to the plate member 45. The plate member 46 is disposed between the plate member 45 and the plate member 58.

Fig. 24 is a plan view showing the supporting device 43. The support device 43 includes a support body 59, a pair of adjustment bolts 60, a pair of adjustment bolts 61, and a pair of adjustment bolts 62.

The support 59 is formed by bending a flat plate. The support 59 includes, for example, a bottom plate 63 and holding plates 64 to 66. The bottom plate 63 has a pair of through holes 63a and a pair of through holes 63b. The through holes 63a and 63b are aligned in a row in the Y direction.

The holding plate 64 extends upward from one end of the bottom plate 63. The holding plate 64 is perpendicular to the X-axis. The adjustment bolt 60 is held by the holding plate 64 so as to be displaceable along the X axis. The holding plate 64 is disposed so as to oppose the plate member 58. The front end of the adjusting bolt 60 abuts against the plate member 58.

The holding plate 65 extends upward from the other end of the bottom plate 63. The holding plate 65 is perpendicular to the Y-axis. The adjustment bolt 61 is held by the holding plate 65 so as to be displaceable along the Y axis. The holding plate 65 is disposed so as to face the plate member 48 of the arm 35. The front end of the adjusting bolt 61 abuts against the plate member 48.

The holding plate 66 extends upward from the other end of the bottom plate 63. The holding plate 66 is perpendicular to the Y-axis. The adjustment bolt 62 is held by the holding plate 66 so as to be displaceable along the Y axis. The holding plate 66 is disposed so as to face the plate member 50 of the arm 36. The front end of the adjusting bolt 62 abuts against the plate member 50.

In the example shown in fig. 23, the support member 59 is placed on the ceiling member 25 such that the bottom plate 63 faces the upper surface 11a of the car room 11. The arm 34 is placed on the bottom plate 63 of the support 59. Thereby, the through-hole 49a, the through-hole 46a, the through-hole 63a, and the through-hole 37c are vertically aligned. The bolt 41 penetrates the arm 35, the arm 34, the support device 43, the ceiling member 25, and the lower mat 37 from above, and is screwed into the nut 38. The through-hole 51a, the through-hole 46b, the through-hole 63b, and the through-hole 37d are vertically arranged. The bolt 42 is passed through the arm 36, the arm 34, the support device 43, the ceiling member 25, and the lower mat 37 from above and screwed into the nut 39.

In the example shown in fig. 23, when the shock-absorbing member 31 receives a force from the surface 22a, the force is transmitted to the holding plate 64 of the support member 59 via the adjusting bolt 60. The force received by the buffer member 31 can be dispersed to the support 59. Similarly, when the cushioning member 32 receives a force from the surface 22b, the force is transmitted to the holding plate 65 of the support body 59 via the adjustment bolt 61. The force received by the cushioning member 32 can be dispersed to the support 59. When the cushioning member 33 receives a force from the surface 22c, the force is transmitted to the holding plate 66 of the support body 59 via the adjusting bolt 62. The force received by the cushioning member 33 can be dispersed to the support 59. Therefore, if the example shown in fig. 23 is employed, the strength of the vibration isolator 15 can be increased.

The adjusting bolt 60 is an example of means for transmitting the force received by the cushion member 31 from the surface 22a to the support member 59. Similarly, the adjusting bolt 61 is an example of means for transmitting the force received by the cushion member 32 from the front surface 22b to the support body 59. The adjusting bolt 62 is an example of a means for transmitting the force received by the buffer member 33 from the surface 22c to the support body 59.

Fig. 25 is a plan view showing another example of the vibration isolator 15. The example shown in fig. 25 differs from the example shown in fig. 23 in the adjusting bolt 61 and the adjusting bolt 62.

In the example shown in fig. 25, one of the pair of adjustment bolts 61 that is closer to the cushion member 32 is denoted by a reference numeral 61a, and the other is denoted by a reference numeral 61b that is farther from the cushion member 32. As in the example shown in fig. 23, the adjusting bolt 61a is held by the holding plate 65 so as to be displaceable along the Y axis. The front end of the adjusting bolt 61a abuts against the plate member 48.

The adjustment bolt 61b is held by the plate member 48 so as to be displaceable along the Y axis. Specifically, the tip end portion of the adjustment bolt 61b is screwed into a nut welded and fixed to the plate member 48. The adjustment bolt 61b penetrates the holding plate 65. The head of the adjustment bolt 61b opposes the surface 65a of the holding plate 65. Surface 65a faces in the Y direction.

Similarly, in the example shown in fig. 25, one of the pair of adjustment bolts 62 closer to the cushion member 33 is denoted by a reference numeral 62a, and the other thereof farther from the cushion member 33 is denoted by a reference numeral 62b. As in the example shown in fig. 23, the adjustment bolt 62a is held by the holding plate 66 so as to be displaceable along the Y axis. The front end of the adjustment bolt 62a abuts against the plate member 50.

The adjustment bolt 62b is held by the plate member 50 so as to be displaceable along the Y axis. Specifically, the tip end portion of the adjustment bolt 62b is screwed into a nut welded and fixed to the plate member 50. The adjustment bolt 62b penetrates the holding plate 66. The head of the adjustment bolt 62b opposes the surface 66a of the holding plate 66. The surface 66a faces in the-Y direction.

In the example shown in fig. 25, when the cushioning member 32 receives a force in the Y direction, the adjuster bolt 61b is pulled in the-Y direction by the plate member 48 having the tip of the adjuster bolt 61a as a fulcrum. Therefore, when the cushioning member 32 receives a force from the surface 22b, the force is transmitted to the holding plate 65 of the support body 59 via the adjustment bolt 61b. The force received by the cushioning material 32 can be dispersed to the support 59. Similarly, when the cushioning member 33 is urged in the-Y direction, the adjuster bolt 62b is pulled in the Y direction by the plate member 50 with the tip of the adjuster bolt 62a as a fulcrum. Therefore, when the cushioning member 33 receives a force from the surface 22c, the force is transmitted to the holding plate 66 of the support body 59 via the adjustment bolt 62b. The force received by the cushioning member 33 can be dispersed to the support 59.

Fig. 26 is a plan view showing another example of the vibration isolator 15. In the example shown in fig. 26, the vibration isolator 15 includes cushion members 31 to 33, arms 34 to 36, a lower pad 37 (not shown), nuts 38 to 39 (not shown), and bolts 41 to 42. The vibration isolator 15 further includes an adjustment bolt 67, an adjustment bolt 68, a pair of adjustment bolts 69, and a pair of adjustment bolts 70.

In the example shown in fig. 26, the arm 34 includes holding plates 71 to 73 in addition to the plate member 45, the plate member 46, and the reinforcing member 47. The plate member 46 extends further in the X direction than one end of the arm 35 and one end of the arm 36. The holding plate 71 extends upward from one end of the portion of the plate member 46 extending in the X direction. The holding plate 71 is perpendicular to the X-axis. That is, the holding plate 71 is disposed parallel to the plate member 45.

The plate member 46 extends further in the Y direction than the one end of the arm 35. The holding plate 72 extends upward from one end of the portion of the plate member 46 that extends in the Y direction. The holding plate 72 is perpendicular to the Y-axis. The adjustment bolt 69 is held by the holding plate 72 so as to be displaceable along the Y axis. The holding plate 72 is disposed so as to face the plate member 48 of the arm 35. The front end of the adjusting bolt 69 abuts against the plate member 48.

The plate member 46 extends further in the-Y direction than the one end of the arm 36. The holding plate 73 extends upward from one end of the portion of the plate member 46 extending in the-Y direction. The holding plate 73 is perpendicular to the Y-axis. The holding plate 73 is arranged in parallel with the holding plate 72. The adjustment bolt 70 is held by the holding plate 73 so as to be displaceable along the Y axis. The holding plate 73 is disposed so as to face the plate member 50 of the arm 36. The front end of the adjusting bolt 70 abuts against the plate member 50.

The arm 35 includes a holding plate 74 in addition to the plate members 48 and 49. The holding plate 74 is perpendicular to the X-axis. The holding plate 74 is disposed so as to face the holding plate 71. The adjustment bolt 67 is held by the holding plate 74 so as to be displaceable along the X axis. Specifically, the front end portion of the adjusting bolt 67 is screwed into a nut that is welded and fixed to the holding plate 74. The adjustment bolt 67 penetrates through an elongated hole (not shown) formed in the holding plate 71. The long hole has a long side in the Y direction. The head of the adjustment bolt 67 is opposed to the surface 71a of the holding plate 71. The surface 71a faces in the X direction.

The arm 36 includes a holding plate 75 in addition to the plate member 50 and the plate member 51. The holding plate 75 is perpendicular to the X-axis. The holding plate 75 is disposed parallel to the holding plate 74. The holding plate 75 is disposed so as to face the holding plate 71. The adjustment bolt 68 is held by a holding plate 75 so as to be displaceable along the X axis. Specifically, the tip end portion of the adjusting bolt 68 is screwed into a nut that is welded and fixed to the holding plate 75. The adjustment bolt 68 penetrates an elongated hole (not shown) formed in the holding plate 71. The long hole has a long side in the Y direction. The head of the adjusting bolt 68 is opposed to the surface 71a of the holding plate 71.

In the example shown in fig. 26, when the cushioning member 31 receives a force from the surface 22a, the force is transmitted to the holding plate 74 of the arm 35 via the adjustment bolt 67. Further, when the cushioning member 31 receives a force from the surface 22a, the force is transmitted to the holding plate 75 of the arm 36 via the adjustment bolt 68. The force received by the shock-absorbing member 31 can be distributed to the arm 35 and the arm 36.

Likewise, when the cushioning member 32 is forced from the surface 22b, the force is transmitted to the holding plate 72 of the arm 34 via the adjustment bolt 69. The force received by the cushioning member 32 can be dispersed to the arm 34. When the cushioning member 33 receives a force from the surface 22c, the force is transmitted to the holding plate 73 of the arm 34 via the adjustment bolt 70. The force received by the cushioning member 33 can be dispersed to the arm 34. Therefore, if the example shown in fig. 26 is used, the strength of the vibration isolator 15 can be improved.

The adjusting bolt 67 is an example of means for transmitting the force received by the shock-absorbing member 31 from the surface 22a to the arm 35. The adjusting bolt 68 is an example of a means for transmitting the force received by the shock-absorbing member 31 from the surface 22a to the arm 36. The adjusting bolt 69 is an example of means for transmitting the force received by the cushion member 32 from the surface 22b to the arm 34. The adjusting bolt 70 is an example of means for transmitting the force received by the cushion member 33 from the surface 22c to the arm 34.
