Description

[Technical field]

[0001] The present invention relates to a support device that supports an air conditioner in a suspended state in a ceiling space. [Background technology]

[0002] 2. Description of the Related Art Conventionally, various support devices that support an air conditioner while hanging it from a ceiling space and allow the installation position of the air conditioner to be adjusted in a horizontal plane have been proposed (Patent Documents 1 to 4).

[0003] For example, the support device in Patent Document 1 provides a support with a mounting hole larger than the diameter of the support bolt that supports the air conditioner, and places a plate member above the mounting hole with an outer size larger than the mounting hole and with a hole in the center through which the support bolt can be inserted, allowing the support bolt to move inside the mounting hole and making it possible to adjust the installation position of the air conditioner.

[0004] Furthermore, the support device in Patent Document 2 connects a first angle member and a second angle member in a criss-cross pattern, attaches a hanging device for attaching a hanging bolt to the first angle member, and attaches a support bolt for supporting the air conditioner to the second angle member, allowing the hanging device to slide along the longitudinal direction of the first angle member and allowing the support bolt to slide along a slit formed in the second angle member, thereby making it possible to adjust the installation position of the air conditioner.

[0005] In addition, the support device of Patent Document 3 connects the upper end of the first ceiling bolt that supports the air conditioner and the lower end of the second ceiling bolt that hangs down into the ceiling space by inserting them into long holes formed in a plate-shaped ceiling position adjustment fitting, making it possible to adjust the position of the first ceiling bolt within the horizontal plane.

[0006] Furthermore, the support device of Patent Document 4 assembles frame members having slits formed in the longitudinal direction in a crisscross pattern, allowing the positions at which the suspension bolts and support bolts are connected to be adjusted along the slits of the frame members. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2017-218835 A [Patent Document 2] JP 2017-146064 A [Patent Document 3] JP 2018-146204 A [Patent Document 4] JP 2020-56464 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, the support device in Patent Document 1 has a narrow range in which the position of the air conditioner can be adjusted in the horizontal plane, making it difficult to use. In order to increase the range in which the position of the air conditioner can be adjusted, the diameter of the mounting hole must be increased, which inevitably increases the size of the plate member and the weight of the support device.

[0009] In contrast, the support devices of Patent Documents 2 to 4 have slits or long holes formed in the angle members and frame members, so that a wider range of adjustment for the position of the air conditioner can be secured than the support device of Patent Document 1. However, in order to further expand the position adjustment range of the air conditioner in the support devices of Patent Documents 2 to 4, the angle members and frame members must be lengthened, and the size of the support device cannot be avoided. In particular, since this type of support device is installed in the ceiling space while supporting the air conditioner, if other hanging objects such as pipes and ducts are installed in the ceiling space, there is a problem that if the support device is made larger, it will interfere with the other hanging objects, making it impossible to install the air conditioner in an appropriate position.

[0010] Furthermore, when the length of the slits or slots formed along the longitudinal direction of the angle members or frame members is increased, the rigidity of the angle members or frame members decreases accordingly. To prevent this, it is necessary to increase the thickness of the angle members or frame members to increase their rigidity. However, when the thickness of the angle members or frame members is increased, the weight of the support device is inevitably increased. Since the support device is installed in the ceiling space during high-altitude work, there is a problem that the workability is significantly reduced when the weight increases.

[0011] The present invention has been made to solve the above-mentioned problems in the conventional art, and aims to provide a support device that allows the position of an air conditioner to be adjusted over a wide range without increasing its size or weight. [Means for solving the problem]

[0012] In order to achieve the above-mentioned object, firstly, the present invention provides a support device that supports a number of support bolts connected to each of a number of mounting pieces provided on a side of an air conditioner and supports the air conditioner in a suspended state, comprising a pair of first frame members arranged parallel to each other in a horizontal plane on the upper surface side of the air conditioner and supporting the support bolts, a pair of second frame members arranged parallel to each other in the horizontal plane on the upper surface side of the air conditioner and perpendicular to the first frame members, and connecting bolts hanging down into a ceiling space, and connecting fittings that connect the first frame members and the second frame members perpendicular to each other, wherein the position at which the support bolts are supported and the connecting position of the connecting fittings are each adjustable along the longitudinal direction of the first frame member, and the position at which the hanging bolts are connected and the connecting position of the connecting fittings are each adjustable along the longitudinal direction of the second frame member.

[0013] Secondly, the present invention provides a support device that supports a number of support bolts connected to each of a number of mounting pieces provided on a side of an air conditioner and supports the air conditioner in a suspended state, the support device comprising a pair of first frame members arranged parallel to each other in a horizontal plane on the upper surface side of the air conditioner and supporting the support bolts, a pair of second frame members arranged parallel to each other in the horizontal plane on the upper surface side of the air conditioner and perpendicular to the first frame members, and connecting bolts that hang down into a ceiling space, and connecting metal fittings that connect the first frame members and the second frame members perpendicular to each other, the first frame members having first connecting portions at both longitudinal ends that connect the connecting metal fittings and support portions that support the support bolts, the first connecting portions being fixed to the first frame members By forming the connecting fitting along the longitudinal direction, the connecting position of the connecting fitting can be adjusted in the longitudinal direction of the first frame member, and by forming the support portion along the longitudinal direction of the first frame member, the position supporting the support bolt can be adjusted in the longitudinal direction of the first frame member. The second frame member has, at both ends in the longitudinal direction, a second connecting portion for connecting the connecting fitting and a hanging portion for connecting and suspending the hanging bolt, and by forming the second connecting portion along the longitudinal direction of the second frame member, the connecting position of the connecting fitting can be adjusted in the longitudinal direction of the second frame member, and by forming the hanging portion along the longitudinal direction of the second frame member, the position connecting the hanging bolt can be adjusted in the longitudinal direction of the second frame member.

[0014] Thirdly, the present invention is a support device having the second configuration, wherein the first frame member has a first plate portion arranged parallel to the upper surface of the air conditioner and a second plate portion forming a right angle relative to the first plate portion, the support portion being formed on the first plate portion and the first connecting portion being formed on the second plate portion, and the second frame member has a first plate portion arranged parallel to the upper surface of the air conditioner and a second plate portion forming a right angle relative to the first plate portion, the hanging portion being formed on the first plate portion, and the second connecting portion being formed on the second plate portion.

[0015] Fourth, the present invention is characterized in that, in a support device having any of the first to third configurations, it further includes a regulating member that presses against an upper surface or a side surface of the air conditioner to regulate relative displacement of the air conditioner.

[0016] Fifthly, the present invention provides a support device having the fourth configuration, wherein the regulating member is attached to the support bolt and presses against a side surface of the air conditioner.

[0017] Sixth, the present invention is a support device having the fifth configuration, characterized in that the regulating member is made of an elastic member of a predetermined shape having a hole in the center through which the support bolt is inserted. Effect of the Invention

[0018] According to the present invention, it becomes possible to adjust the position of an air conditioner over a wider range than before, without increasing the size and weight of the support device. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings referred to below, common members are designated by the same reference numerals, and redundant description thereof will be omitted.

[0021] Fig. 1 is a perspective view showing a support device 1 according to one embodiment of the present invention. Fig. 2 is a perspective view showing a state in which the support device 1 supports an air conditioner 100. The XYZ three-dimensional coordinate system shown in Fig. 1 and Fig. 2 is a coordinate system in which the XY plane is the horizontal plane and the Z direction is the vertical direction, and is a coordinate system common to the coordinate systems shown in other figures.

[0022] As shown in FIG. 2, the support device 1 supports a plurality of support bolts 43 connected to a plurality of mounting pieces 110 provided on the side surface of the air conditioner 100, and supports the air conditioner 100 in a state of being suspended in the ceiling space. For example, the plurality of mounting pieces 110 are provided on the side surface of the air conditioner 100 at the four corners. As shown in FIG. 1 and FIG. 2, the support device 1 includes a pair of first frame members 10, 10 arranged parallel to each other in a horizontal plane on the upper surface side of the air conditioner 100. The support device 1 also includes a pair of second frame members 20, 20 arranged parallel to each other in a horizontal plane on the upper surface side of the air conditioner 100 and perpendicular to the first frame member 10. The support device 1 also includes a connecting fitting 30 that connects the pair of first frame members 10, 10 and the pair of second frame members 20, 20 to each other in a perpendicular state.

[0023] The first frame member 10 is arranged so that it traverses the top surface side of the air conditioner 100 in the Y direction, with both ends located above mounting pieces 110 provided on the side surfaces of the air conditioner 100. The first frame member 10 is formed, for example, from an angle iron with an L-shaped cross section, and has a horizontal plate portion 11 parallel to the horizontal plane, and a vertical plate portion 12 standing at a right angle from a side edge of the horizontal plate portion 11. The horizontal plate portion 11 is a first plate portion arranged parallel to the top surface of the air conditioner 100. The vertical plate portion 12 is a second plate portion that forms a right angle with the top surface of the air conditioner 100.

[0024] The first frame member 10 has first connecting portions 13, 13 that connect the connecting fittings 30 to both ends of the vertical plate portion 12 in the longitudinal direction. For example, the first connecting portions 13, 13 are formed as elongated holes extending along the longitudinal direction of the vertical plate portion 12. The elongated holes of the first connecting portions 13, 13 are formed in two locations on both end sides of the first frame member 10.

[0025] The first frame member 10 has support portions 14, 14 that support the support bolt 43 on both ends of the horizontal plate portion 11 in the longitudinal direction. For example, the support portions 14, 14 are formed as elongated holes extending along the longitudinal direction of the horizontal plate portion 11. The elongated holes of the support portions 14, 14 are formed in two locations on both ends of the first frame member 10.

[0026] The support bolt 43 is a rod-shaped member with a male screw formed on the outer circumferential surface. The upper end of the support bolt 43 is inserted into the support part 14, and fixed to the horizontal plate part 11 of the first frame member 10 by clamping the horizontal plate part 11 with two nuts. A cylindrical or conical vibration-proof member 44 made of an elastic material such as rubber is attached to the lower end of the support bolt 43, and a nut 45 is attached to the lower side of the vibration-proof member 44. The nut 45 supports the lower surface of the vibration-proof member 44. The lower end of the support bolt 43 is attached in a state in which the vibration-proof member 44 is disposed on the lower surface side of the mounting piece 110. As a result, the mounting piece 110 of the air conditioner 100 is placed on the vibration-proof member 44. Therefore, the support bolt 43 supports the mounting piece 110 provided on the side surface of the air conditioner 100 via the vibration-proof member 44. By supporting the air conditioner 100 via the vibration-isolating member 44, the support device 1 can prevent vibrations generated during operation of the air conditioner 100 from being transmitted to the upper floor via the support device 1 and the hanging bolts 41.

[0027] The support bolt 43 is attached by being inserted into the support portion 14 formed as an elongated hole. Therefore, when one of two nuts attached to sandwich the horizontal plate portion 11 is loosened, the support bolt 43 can move along the longitudinal direction of the support portion 14. In other words, the position at which the first frame member 10 supports the support bolt 43 can be adjusted along the longitudinal direction (Y direction) of the first frame member 10.

[0028] The second frame member 20 is disposed so as to cross the upper surface side of the air conditioner 100 in the X direction, and both ends of the second frame member 20 extend further outward beyond the pair of first frame members 10, 10. The second frame member 20, like the first frame member 10, is formed, for example, of an angle bar having an L-shaped cross section, and has a horizontal plate portion 21 parallel to the horizontal plane and a vertical plate portion 22 hanging down at a right angle from the side edge of the horizontal plate portion 21. The horizontal plate portion 21 is a first plate portion disposed parallel to the upper surface of the air conditioner 100. The vertical plate portion 22 is a second plate portion that forms a right angle with the upper surface of the air conditioner 100. The upper end of the vertical plate portion 12 of the first frame member 10 and the lower end of the vertical plate portion 22 of the second frame member 20 are disposed so as to intersect in a state of contact or closeness with each other.

[0029] The second frame member 20 has second connecting portions 23, 23 that connect the connecting fittings 30 to both ends of the vertical plate portion 22 in the longitudinal direction. For example, the second connecting portions 23, 23 are formed as elongated holes extending along the longitudinal direction of the vertical plate portion 22. The elongated holes of the second connecting portions 23, 23 are formed in two locations on both end sides of the second frame member 20.

[0030] The second frame member 20 also has hanging portions 24, 24 at both ends in the longitudinal direction of the horizontal plate portion 21 for connecting and suspending hanging bolts 41. For example, the hanging portions 24, 24 are formed as elongated holes extending along the longitudinal direction of the horizontal plate portion 21. The elongated holes of the hanging portions 24, 24 are formed in two locations on both ends of the second frame member 20.

[0031] The hanging bolt 41 is a bolt that hangs down into the ceiling space and connects the support device 1 to a structure such as an upper floor floor slab. For example, the upper end of the hanging bolt 41 is fixed to an anchor embedded in the structure such as an upper floor floor slab. The lower end of the hanging bolt 41 is inserted into the hanging part 24 and fixed to the horizontal plate part 21 by fastening two nuts 42 that sandwich the horizontal plate part 21 of the second frame member 20.

[0032] The hanging bolt 41 is attached by being inserted through the hanging portion 24 formed as an elongated hole. Therefore, when one of the two nuts 42 attached to sandwich the horizontal plate portion 21 is loosened, the hanging bolt 41 can move along the longitudinal direction of the hanging portion 24. In other words, the position where the hanging bolt 41 is connected to the second frame member 20 can be adjusted along the longitudinal direction (X direction) of the second frame member 20.

[0033] 1 and 2, the first frame member 10 is disposed so that the horizontal plate portion 11 is located below the vertical plate portion 12. The second frame member 20 is disposed so that the horizontal plate portion 21 is located above the vertical plate portion 22. Therefore, at the intersection where the first frame member 10 and the second frame member 20 intersect, the horizontal plate portion 11 of the first frame member 10 and the horizontal plate portion 21 of the second frame member 20 face each other with a gap equivalent to the height of the two vertical plate portions 12, 22 between them. Therefore, at the intersection where the first frame member 10 and the second frame member 20 intersect, a certain space is formed between the two horizontal plate portions 11, 21.

[0034] Here, the upper end of the support bolt 43 is attached to the horizontal plate portion 11 so as not to exceed the upper end position of the vertical plate portion 12 of the first frame member 10. Therefore, when one of the two nuts attached to sandwich the horizontal plate portion 11 is loosened to move the support bolt 43 along the longitudinal direction of the support portion 14, the support bolt 43 can be moved beyond the position of the intersection where the first frame member 10 and the second frame member 20 intersect.

[0035] In addition, the lower end of the hanging bolt 41 is attached to the horizontal plate portion 21 so as not to exceed the lower end position of the vertical plate portion 22 of the second frame member 20. Therefore, when one of the two nuts 42 attached to sandwich the horizontal plate portion 21 is loosened to move the hanging bolt 41 along the longitudinal direction of the hanging portion 24, the hanging bolt 41 can be moved beyond the intersection position where the first frame member 10 and the second frame member 20 intersect.

[0036] Fig. 3 is a diagram showing a manner in which the first frame member 10 and the second frame member 20 are connected by the connecting fitting 30. Note that Fig. 3 illustrates a connecting fitting 30 provided at one of four locations on the support device 1.

[0037] The connecting fitting 30 is a fitting formed integrally with a first plate portion 31 joined to the vertical plate portion 22 of the second frame member 20 and a second plate portion 32 joined to the vertical plate portion 12 of the first frame member 10. A plurality of holes 33, 33 formed by burring are provided at a predetermined interval in the X direction on the upper part of the first plate portion 31. Female screws 34 are formed inside the plurality of holes 33, 33. The second plate portion 32 is perpendicular to the first plate portion 31 and has a plurality of holes 35, 35 formed by burring at a predetermined interval in the Y direction. Female screws 36 are formed inside the plurality of holes 35, 35.

[0038] As shown in FIG. 3, the connecting fitting 30 is arranged in a state in which the first plate portion 31 is joined to the vertical plate portion 22 of the second frame member 20, and the second plate portion 32 is joined to the vertical plate portion 12 of the first frame member 10. Then, the connecting fitting 30 is fixed to the vertical plate portion 22 of the second frame member 20 by fastening a fastening member 37 such as a bolt through a second connecting portion 23 formed on the vertical plate portion 22 of the second frame member 20 to each of a plurality of holes 33, 33 provided in the first plate portion 31. Also, the connecting fitting 30 is fixed to the vertical plate portion 12 of the first frame member 10 by fastening a fastening member 38 such as a bolt through a first connecting portion 13 formed on the vertical plate portion 12 of the first frame member 10 to each of a plurality of holes 35, 35 provided in the second plate portion 32. In this way, the connecting fitting 30 connects the intersections of the first frame member 10 and the second frame member 20 to each other.

[0039] Here, if there is one fastening member 38 that fixes the connecting fitting 30 to the first frame member 10, the connecting fitting 30 may rotate around the axis of the fastening member 38 and change its posture. Also, if there is one fastening member 37 that fixes the connecting fitting 30 to the second frame member 20, the connecting fitting 30 may rotate around the axis of the fastening member 37 and change its posture. However, the connecting fitting 30 of this embodiment is fixed to the first frame member 10 using multiple fastening members 38, and is fixed to the second frame member 20 using multiple fastening members 37. Therefore, the connecting fitting 30 of this embodiment does not undergo the above-mentioned posture change, and is fixed to each of the first frame member 10 and the second frame member 20 in a stable posture.

[0040] The long hole of the first connecting portion 13 provided in the vertical plate portion 12 of the first frame member 10 is formed longer than the interval between the multiple holes 35, 35. Therefore, the connecting fitting 30 is movable along the longitudinal direction (Y direction) of the first connecting portion 13 by loosening the fastening member 38. In other words, when the fastening member 38 is loosened, the first frame member 10 can be moved in the longitudinal direction (Y direction) relative to the connecting fitting 30. Therefore, when the fastening member 38 is loosened, the intersection point where the first frame member 10 and the second frame member 20 intersect can be moved in the longitudinal direction (Y direction) of the first frame member 10.

[0041] Furthermore, the long hole of the second connecting portion 23 provided in the vertical plate portion 22 of the second frame member 20 is formed longer than the interval between the multiple holes 33, 33. Therefore, the connecting fitting 30 can be moved along the longitudinal direction (X direction) of the second connecting portion 23 by loosening the fastening member 37. In other words, when the fastening member 37 is loosened, the second frame member 20 can be moved in the longitudinal direction (X direction) relative to the connecting fitting 30. Therefore, when the fastening member 37 is loosened, the intersection point where the first frame member 10 and the second frame member 20 intersect can be moved in the longitudinal direction (X direction) of the second frame member 20.

[0042] The connecting fittings 30 as described above are arranged at the four intersections where the first frame member 10 and the second frame member 20 intersect. Of the multiple connecting fittings 30 arranged at the four intersections, two connecting fittings 30 have the structure shown in Fig. 3. The other two connecting fittings 30 have a structure obtained by flipping the structure shown in Fig. 3 left and right.

[0043] In the support device 1 configured as described above, when adjusting the position of the hanging bolt 41 in the X direction, the position of the hanging bolt 41 can be adjusted beyond the range of the long hole formed as the hanging portion 24. FIG. 4 is a diagram showing the position adjustment range of the hanging bolt 41. FIG. 4(a) shows a state in which the second frame member 20 is moved to the right relative to the first frame member 10, and FIG. 4(b) shows a state in which the second frame member 20 is moved to the left relative to the first frame member 10. As shown in FIG. 4(a), when the second frame member 20 is moved to the right of the first frame member 10, the range in which the hanging bolt 41 can be adjusted in the X direction is the range L1 of the long hole formed as the hanging portion 24. Also, as shown in FIG. 4(b), when the second frame member 20 is moved to the left of the first frame member 10, the range in which the hanging bolt 41 can be adjusted in the X direction is the range L1 of the long hole formed as the hanging portion 24. However, the range L1 of the elongated hole shown in Fig. 4(a) and the range L1 of the elongated hole shown in Fig. 4(b) are shifted from each other in the X direction. Therefore, by moving the second frame member 20 in the X direction relative to the connecting fitting 30, the support device 1 can exceed the range L1 of the elongated hole formed as the hanging portion 24 and set the range in which the hanging bolt 41 can be adjusted to L2.

[0044] That is, the second frame member 20 of the support device 1 is capable of adjusting the position where the hanging bolt 41 is connected and the connection position where the connecting fitting 30 is connected along the longitudinal direction (X direction) of the second frame member 20, so that two-stage position adjustment in the X direction is possible, and this two-stage position adjustment ensures a wider adjustment range than before. Therefore, it is no longer necessary to form the hanging portion 24 for connecting the hanging bolt 41 long in the longitudinal direction of the second frame member 20, and a decrease in the rigidity of the second frame member 20 can be suppressed.

[0045] Therefore, this support device 1 does not require lengthening the second frame member 20 or increasing the thickness of the second frame member 20 to increase its rigidity, and makes it possible to adjust the installation position of the air conditioner 100 in the X direction over a wide range without increasing the size or weight of the second frame member 20.

[0046] In addition, when adjusting the position of the support bolt 43 in the Y direction, the support device 1 can adjust the position of the support bolt 43 beyond the range of the long hole formed as the support part 14. FIG. 5 is a diagram showing the position adjustment range of the support bolt 43. FIG. 5(a) shows a state in which the first frame member 10 is moved upward relative to the second frame member 20, and FIG. 5(b) shows a state in which the first frame member 10 is moved downward relative to the second frame member 20. As shown in FIG. 5(a), when the first frame member 10 is moved upward relative to the second frame member 20, the range in which the support bolt 43 can be adjusted in the Y direction is the range L3 of the long hole formed as the support part 14. Also, as shown in FIG. 5(b), when the first frame member 10 is moved downward relative to the second frame member 20, the range in which the support bolt 43 can be adjusted in the Y direction is the range L3 of the long hole formed as the support part 14. However, the range L3 of the long hole shown in FIG. 5(a) and the range L3 of the long hole shown in FIG. 5(b) are mutually shifted in the Y direction. Therefore, by moving the first frame member 10 in the Y direction relative to the connecting fitting 30, the support device 1 can adjust the support bolt 43 beyond the range L3 of the long hole formed as the support portion 14, to a range L4.

[0047] In other words, the first frame member 10 of the support device 1 is capable of adjusting the position that supports the support bolt 43 and the connecting position that connects the connecting fitting 30 along the longitudinal direction (Y direction) of the first frame member 10, allowing two-stage position adjustment in the Y direction, and this two-stage position adjustment ensures a wider adjustment range than before. Therefore, it is no longer necessary to form the support part 14 that supports the support bolt 43 long in the longitudinal direction of the first frame member 10, and a decrease in the rigidity of the first frame member 10 can be suppressed.

[0048] Therefore, this support device 1 makes it possible to adjust the installation position of the air conditioner 100 in the Y direction over a wide range, without the need to lengthen the first frame member 10 or increase the thickness of the first frame member 10 to increase its rigidity, and without increasing the size and weight of the first frame member 10. As a result, the support device 1 makes it possible to adjust the position of the air conditioner 100 over a wide range in the horizontal plane, without increasing its size and weight.

[0049] Incidentally, the support bolts 43 connected to the support parts 14 of the first frame member 10 may vibrate significantly when an earthquake occurs. When the support bolts 43 vibrate, the air conditioner 100 also vibrates significantly. Furthermore, when the support bolts 43 vibrate, a phenomenon occurs in which the first frame member 10 twists in sync with the vibration of the support bolts 43. Therefore, it is preferable that the support device 1 be provided with a mechanism for suppressing the vibration of the air conditioner 100 when an earthquake occurs.

[0050] 6 is an enlarged side view showing a portion of the air conditioner 100 supported by the support device 1, and shows an example in which a restricting member 50 is attached to the support bolt 43. The restricting member 50 is attached to the support bolt 43, and restricts relative displacement between the support bolt 43 and the air conditioner 100 by pressing against a side surface 100a of the air conditioner 100.

[0051] FIG. 7 is a diagram showing the restricting member 50 shown in FIG. 6. As shown in FIG. 7(a), the restricting member 50 includes a long nut 51, a bolt 53, and a pressing member 54 attached to the tip of the bolt 53. The long nut 51 has a predetermined length in the axial direction, and has a screw hole 51a at the center of the axis into which the bolt 53 can be screwed. The long nut 51 also has a screw hole 52 formed in the radial direction of the long nut 51 and penetrating the outer peripheral side surface. The screw hole 52 can be screwed into the support bolt 43 as shown in FIG. 7(b). The bolt 53 is attached to the screw hole 51a from one end of the long nut 51. The pressing member 54 provided at the tip of the bolt 53 is formed of an elastic material such as rubber, and presses the side surface 100a of the air conditioner 100. 7(b), by rotating the bolt 53 in the R direction, the length of the bolt 53 protruding from one end of the long nut 51 can be adjusted, and the pressing force with which the pressing member 54 presses the side surface 100a of the air conditioner 100 can be adjusted. By pressing the side surface 100a of the air conditioner 100 with a predetermined pressing force, such a restricting member 50 can suppress relative displacement between the support bolt 43 and the air conditioner 100 when an earthquake occurs.

[0052] Such a restricting member 50 can not only suppress vibration of the air conditioner 100, but also vibration of the support bolts 43. Therefore, by providing the restricting member 50, the twisting phenomenon of the first frame member 10 can also be reduced.

[0053] Fig. 8 is a diagram showing a restricting member 50 different from that shown in Fig. 6. This restricting member 50 is attached to the horizontal plate portion 11 of the first frame member 10, and restricts relative displacement between the air conditioner 100 and the first frame member 10 by pressing against the upper surface 100b of the air conditioner 100.

[0054] For example, the restricting member 50 may be attached to the support portion 14 formed on the horizontal plate portion 11, or may be attached to a hole different from the support portion 14. The restricting member 50 shown in FIG. 8 is attached to the horizontal plate portion 11 by fastening two nuts 55, 56 attached to the bolt 53 while sandwiching the horizontal plate portion 11. A pressing member 54 is attached to the tip of the bolt 53. The pressing force with which the pressing member 54 presses the upper surface 100b of the air conditioner 100 can be adjusted by adjusting the length by which the bolt 53 protrudes downward from the lower surface of the horizontal plate portion 11. Such a restricting member 50 can suppress the relative displacement between the first frame member 10 and the air conditioner 100 when an earthquake occurs by pressing the upper surface 100b of the air conditioner 100 with a predetermined pressing force. As a result, the vibration of the support bolt 43 can also be suppressed. Therefore, by providing the restricting member 50 shown in FIG. 8, the twisting phenomenon of the first frame member 10 can also be reduced.

[0055] Figure 9 is a diagram showing a restricting member 50 which is further different from those in Figures 6 and 8. This restricting member 50 is attached to the support bolt 43, and restricts relative displacement between the support bolt 43 and the air conditioner 100 by pressing against the side surface 100a of the air conditioner 100.

[0056] FIG. 10 is a diagram showing the restricting member 50 shown in FIG. 9. As shown in FIG. 10, the restricting member 50 is composed of a disk-shaped elastic member 58. The elastic member 58 is formed in a disk shape with a predetermined radius D2, and a hole 59 through which the support bolt 43 is inserted is formed in the center thereof. As shown in FIG. 9, the radius D2 of the elastic member 58 is formed to be the same size as the distance D1 between the support bolt 43 attached to the mounting piece 110 and the side surface 100a of the air conditioner 100, or a size slightly larger than that. Therefore, when the support bolt 43 is inserted into the hole 59 in the center of the elastic member 58, the outer peripheral surface of the elastic member 58 abuts against the side surface 100a of the air conditioner 100, and is attached in a state in which it presses against the side surface 100a.

[0057] 11 is a perspective view showing a state in which elastic members 58 are attached to the four support bolts 43 that support the air conditioner 100. By attaching the elastic members 58 to each of the four support bolts 43, it is possible to suppress relative displacement between the support bolts 43 and the air conditioner 100 when an earthquake occurs. The elastic members 58 can also reduce the twisting phenomenon of the first frame member 10.

[0058] When attaching the restricting member 50 to the support bolt 43, it is preferable to attach it to the upper side rather than the center of the support bolt 43, more specifically, to a position near the upper end, as shown in Fig. 9. By attaching the restricting member 50 to a position near the upper end of the support bolt 43, the restricting member 50 can be attached to a position close to the first frame member 10, which increases the effect of reducing the twisting phenomenon of the first frame member 10.

[0059] Also, in FIG. 10, the elastic member 58 is formed in a disk shape. However, the shape of the elastic member 58 is not limited to a disk shape, and may be formed in any predetermined shape including a disk shape. For example, the elastic member 58 may be formed in a polygonal shape such as a triangle or a rectangle. By forming the elastic member 58 in a polygonal shape, the area for pressing the side surface 100a of the air conditioner 100 can be increased compared to a disk shape. Therefore, there is an advantage that the effect of reducing the twisting phenomenon of the first frame member 10 can be further improved. When the elastic member 58 is formed in a polygonal shape, it is preferable to form it in a regular polygon. By forming it in a regular polygonal shape, there is an advantage that the pressing force can be made equal regardless of which side of the polygon is abutted against the side surface 100a of the air conditioner 100.

[0060] As described above, the support device 1 of this embodiment includes a pair of first frame members 10, 10 that are arranged parallel to each other in a horizontal plane on the upper surface side of the air conditioner 100 and support the support bolt 43, a pair of second frame members 20, 20 that are arranged parallel to each other in a horizontal plane on the upper surface side of the air conditioner 100 and perpendicular to the first frame members 10, 10 and connect the hanging bolt 41 that hangs down into the ceiling space, and a connecting metal fitting 30 that connects the first frame members 10, 10 and the second frame members 20, 20 in a mutually perpendicular state. The position where the first frame member 10 supports the support bolt 43 and the connecting position of the connecting metal fitting 30 are each adjustable along the longitudinal direction of the first frame member 10. In addition, the position where the hanging bolt 41 is connected and the connecting position of the connecting metal fitting 30 are each adjustable along the longitudinal direction of the second frame member 20. The support device 1 having such a configuration is capable of adjusting the position of the air conditioner 100 in a wider range than before, without increasing in size or weight.

[0061] In addition, when adjusting the position of the support bolt 43 along the long hole formed as the support part 14, the upper end of the support bolt 43 protruding upward from the upper surface of the horizontal plate part 11 does not come into contact with the second frame member 20 and the connecting fitting 30. Therefore, when moving the support bolt 43 along the longitudinal direction of the support part 14, the support device 1 has the advantage that it is possible to move the support bolt 43 beyond the intersection point where the first frame member 10 and the second frame member 20 intersect, and it is easy to adjust the position over a wide range. Similarly, when adjusting the position of the connection of the suspension bolt 41 along the long hole formed as the hanging part 24, the lower end of the suspension bolt 41 protruding downward from the lower surface of the horizontal plate part 21 does not come into contact with the first frame member 10 and the connecting fitting 30. Therefore, when moving the suspension bolt 41 along the longitudinal direction of the hanging part 24, the support device 1 has the advantage that it is possible to move the suspension bolt 41 beyond the intersection point where the first frame member 10 and the second frame member 20 intersect, and it is easy to adjust the position over a wide range.

[0062] The support device 1 as described above is integrally assembled to the air conditioner 100, for example, at a factory. Once the support device 1 is assembled to the air conditioner 100 at the factory, the air conditioner 100 with the support device 1 assembled is transported from the factory to the installation site. At this time, if multiple air conditioners 100 with the support devices 1 assembled can be loaded onto a transport truck or the like in a vertically stacked state, transportation efficiency can be improved.

[0063] 12 is a perspective view showing a transport cart 200 capable of carrying a plurality of air conditioners 100, each having a support device 1 assembled thereto, in a vertically stacked state. The transport cart 200 has a base 210 to which a plurality of wheels 211 are attached, and four support columns 220 extending upward from the four corners of the base 210. The transport cart 200 has support parts 230 arranged at a predetermined interval in the vertical direction on the four support columns 220. For example, the support part 230 is arranged in the front-rear direction between a pair of support columns 220, 220 located on the right side of the transport cart 200, and is also arranged in the front-rear direction between a pair of support columns 220, 220 located on the left side of the transport cart 200. The support parts 230 provided on the left and right sides are arranged at the same height position of the support columns 220, and both ends thereof are fixed to the pair of support columns 220, 220.

[0064] The air conditioner 100 to which the support device 1 is attached is mounted on the transport cart 200, for example, with both ends of the first frame member 10 placed on the support parts 230. The vertical interval between the multiple support parts 230 is formed to be larger than the height dimension of the air conditioner 100 to which the support device 1 is attached. Therefore, as shown in FIG. 12, the transport cart 200 can carry multiple air conditioners 100 to which the support device 1 is attached in a vertically stacked state. In addition, the transport cart 200 does not have a cross member arranged on the front side thereof that crosses between the supports 220, 220. Therefore, the transport cart 200 has an opening 240 on the front side for taking the air conditioner 100 in and out. When the air conditioner 100 is loaded on the transport cart 200, or when the air conditioner 100 loaded on the transport cart 200 is unloaded, this can be done through the opening 240, which provides excellent workability.

[0065] The air conditioners 100 to which the support device 1 has been assembled in the factory are stacked one above the other on a transport cart 200 as shown in Fig. 12 and loaded onto a transport truck or the like and transported to the installation site. As a result, it is possible to improve the efficiency of transportation from the factory to the installation site.

[0066] An embodiment of the present invention has been described above. However, the present invention is not limited to the embodiment described above. In other words, the present invention can be applied to various modified examples other than the configuration described in the embodiment above.

[0067] For example, in the above embodiment, an example was described in which the first frame member 10 is installed in a state where it does not contact the upper surface of the air conditioner 100. However, the first frame member 10 may be installed in a state where it contacts the upper surface of the air conditioner 100. In this case, when fixing the support bolt 43 to the support portion 14 of the first frame member 10, it is preferable to tighten the nut so that a strong axial force (tensile force) is generated in the support bolt 43 between the mounting piece 110 and the horizontal plate portion 11. By applying an axial force to the support bolt 43, it is possible to suppress the vibration of the support bolt 43, and it is possible to suppress the air conditioner 100 from vibrating greatly in the event of an earthquake. In this case, there is an advantage that there is no need to attach the above-mentioned restricting member 50, and the installation work of the air conditioner 100 can be made more efficient.

[0068] In the above embodiment, the configuration has been described in which the first frame member 10 is disposed below the second frame member 20. However, this is not limited to this, and a configuration example in which the first frame member 10 is disposed above the second frame member 20 may also be adopted. [Explanation of symbols]
