Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional work machine, the user has to remove the mist device during maintenance of the work machine or the like, which is troublesome.

[0005] An object of the present invention is to provide a mount fixed to an open cab type vehicle, which reduces the possibility of interfering with vehicle maintenance work, work for holding an object, etc. more than before.

Means for Solving the Problems

[0006] A frame according to one aspect of the present invention is a frame fixed to an open-cabin type vehicle having a first support column and a second support column, comprising: a base having a holding portion for holding an object; a first fixing portion fixed to the first support column of the vehicle; a second fixing portion fixed to the second support column of the vehicle; a first support member connected to each of the base and the first fixing portion, which supports the base so as to be displaceable between a first position and a second position which is a position displaced relative to the first fixing portion and the second fixing portion with respect to the first position; and a first locking mechanism having a first locking member which is displaceable between a first locking position and a first release position, wherein when the first locking member is in the first locking position, the first locking member enters into the first trajectory of the base when the base is displaced from the first position to the second position, restricting the base from being displaced from the first position to the second position, and when the first locking member is in the first release position, the first locking member retracts from the first trajectory, allowing the base to be displaced from the first position to the second position.

[0007] The first support member of the frame in this embodiment contributes to reducing the possibility of the frame interfering with vehicle maintenance work or work involving holding objects, by displacing the base between a first position and a second position. The first locking mechanism of the frame contributes to restricting the base from displacing from the first position to the second position. The first locking mechanism of the frame contributes to reducing malfunctions caused by the base displacing from the first position to the second position unintentionally by the user.

Mode for Carrying Out the Invention

[0009] Hereinafter, an embodiment embodying the present invention will be described in order with reference to the drawings. The following description uses left and right, front and rear, and up and down indicated by arrows in the drawings. Referring to FIGS. 1 to 4, the vehicle 9 to which the air conditioning system 1 of the present embodiment is mounted will be described. The vehicle 9 of the present embodiment is an open-cabin type forklift.

[0010] The vehicle 9 includes a vehicle body 91, a driver's seat 92, a mast 93, forks 94, columns 951, 952, a first support column 961, a second support column 962, a head guard 98, and lamps 991, 992. The vehicle body 91 houses a structure that generates power such as an engine and a power battery inside, and holds tires at the four corners. The driver's seat 92 is provided on the upper part of the vehicle body 91. The mast 93 is provided at the front end of the vehicle body 91 and extends in the vertical direction. The forks 94 are movable in the vertical direction along the mast 93.

[0011] Column 951 extends diagonally upward and backward from the front right portion of the vehicle body 91 relative to the driver's seat 92, then curves backward and extends horizontally. Column 952 extends diagonally upward and backward from the front left portion of the vehicle body 91 relative to the driver's seat 92, then curves backward and extends horizontally. First support column 961 extends upward from the rear right portion of the vehicle body 91 relative to the driver's seat 92. The upper end of the first support column 961 is connected to the rear end of the underside of column 951. Second support column 962 extends upward from the rear left portion of the vehicle body 91 relative to the driver's seat 92. The upper end of the second support column 962 is connected to the rear end of the underside of column 952. The driver's seat 92 is positioned between the first support column 961 and the second support column 962 in the left-right direction. The front, rear, left, and right directions of the driver's seat 92 are open. In other words, vehicle 9 can be described as an open-cabin type forklift in which the driver's seat 92 is open in the front, rear, left, and right directions. The open-cabin type vehicle 9 is not limited to vehicles in which the driver's seat 92 is open in the front, rear, left, and right directions, but also includes vehicles in which a portion of the space where the driver and passengers sit is open in the front, rear, left, and right directions and communicates with the outside. Ramp 991 is a rectangular parallelepiped that is long in the vertical direction and is installed on the back of the first support column 961. Ramp 992 is a rectangular parallelepiped that is long in the vertical direction and is installed on the back of the second support column 962. The upper end position of the driver's seat 92 is within the vertical extension range of ramps 991 and 992. The longitudinal direction F1 of the first support column 961 and the longitudinal direction F2 of the second support column 962 are each slightly inclined towards the driver's seat 92 with respect to the vertical direction.

[0012] Referring to Figures 2 to 20, the air conditioning system 1 installed in the vehicle 9 will be described. As shown in Figures 2 to 4, the air conditioning system 1 comprises an air conditioner 2 and a mounting base 3, and the air conditioner 2 is fixed via the mounting base 3 behind the driver's seat 92 of the vehicle 9 and above the rear of the vehicle body 91. The air conditioning system 1 will be described below with the following position as the reference position, where the longitudinal direction K1 of the air conditioner 2 coincides with the longitudinal direction K2 of the mounting base 3, and the air outlet 20 of the air conditioner 2 is positioned on the side of the mounting base 3 where the first column fixing part 13 is provided in the longitudinal direction K2. The longitudinal direction K1 of the air conditioner 2, the longitudinal direction K2 of the mounting base 3, and the longitudinal direction K3 of the base 4 are also simply referred to as the longitudinal direction K. When the air conditioning system 1 is in the reference position, the longitudinal direction K is the left-right direction. Of the two directions parallel to the longitudinal direction K, the right is also called the first direction and the left is also called the second direction. One example of a fastening member used in this embodiment is a bolt, which is fastened by screwing it into a threaded hole formed in a hole through which the bolt is inserted.

[0013] The air conditioner 2 in this embodiment is, as an example, an evaporative cooling type spot cooler. The air conditioner 2 comprises a housing 21, an air outlet 20, a duct 23, and a water inlet 19. The housing 21 is shaped like a rectangular parallelepiped, elongated in the left-right direction. The air outlet 20 is provided on the upper right end, which is one end of the housing 21 in the longitudinal direction K1. The duct 23 is connected to the air outlet 20, extends upward from the air outlet 20, and is then bent forward. The tip 22 of the duct 23 is directed toward the driver's seat 92 of the vehicle 9 and is located in front of the front end of the first support column 961.

[0014] As shown in Figures 2 to 5, the air conditioner 2 further includes a power supply unit 39, a tank 24, a cooling unit 36, a fan 38, and fixed parts 26, 27, and 17. The power supply unit 39 is either a power harness extending from one end of the housing 21 in the longitudinal direction K1, or a power battery. If the power supply unit 39 is a power harness, the power harness is connected to the power supply of a vehicle 9 on which the mounting frame 3 is attached, for example. If the power supply unit 39 is a power battery, the power battery may be provided either inside or outside the housing 21, or it may be provided integrally with the housing 21. In this embodiment, the power supply unit 39 includes a power harness extending from a side surface 37 located on one side of the housing 21 in the longitudinal direction K1. The air outlet 20 is provided at one end of the housing 21 in the longitudinal direction K1. The air conditioner 2 is held by the support portion 41 of the frame 3 with the air outlet 20 positioned at the right end of the upper surface 35 of the housing 21.

[0015] The tank 24 is a rectangular parallelepiped container having a water supply section 18 at its bottom, and holds liquid for supply to the cooling section 36. The liquid is, for example, water. The water supply section 18 engages with a water inlet 19 provided in the housing 21. At least a portion of the tank 24 is positioned facing one side of the width direction W, which intersects the longitudinal direction F1 of the first support column 961 and the longitudinal direction K of the base 4. In this embodiment, the width direction W is the front-to-back direction, and one side of the width direction W is the rear. The rear surface of the tank 24 is the widest surface of the tank 24 and constitutes the rear surface of the housing 21, which is one side of the width direction W. In the front-to-back direction, the tank 24 is located behind the outlet 20. A forward-recessed gripping section 25 is formed on the upper part of the rear surface of the tank 24. As shown in state U3 of Figure 5, the tank 24 is detachable from the housing 21. When removing the tank 24 from the housing 21, the user of the air conditioning system 1 can grip it by hooking their finger or other operating body onto the gripping part 25.

[0016] As shown in Figure 3, the cooling unit 36 ​​and the fan 38 are provided inside the housing 21. The cooling unit 36 ​​is configured to cool air and includes, for example, at least one of a sensible heat exchanger and a vaporization element. The sensible heat exchanger is a component that exchanges sensible heat between two air sources. The vaporization element is, for example, a filter into which water is supplied, and is a component that cools the air using the heat of vaporization when the supplied water evaporates in the filter. In this embodiment, the cooling unit 36 ​​includes a vaporization filter that absorbs liquid supplied from the tank 24. The cooling unit 36 ​​cools the surrounding air using the heat of vaporization of the liquid absorbed by the vaporization filter. The fan 38 is driven by power supplied from the power supply unit 39 and blows the air cooled by the cooling unit 36 ​​out of the outlet 20 to the outside of the housing 21. The fan 38 may be any fan, and can be selected from, for example, a centrifugal fan such as a sirocco fan and a propeller fan.

[0017] As shown in state U1 in Figure 5, the fixed portion 26 is a pair of front and rear screw holes formed on the upper right side of the housing 21. The fixed portion 27 is a pair of front and rear screw holes formed on the upper left side of the housing 21. The fixed portion 17 is a total of six screw holes, three in the left-right direction and two in the front-rear direction, provided at the bottom of the housing 21. As shown in Figures 2 and 3, the air conditioning system 1 includes fasteners 49 and 50 that are detachably fixed to the fixed portions 26 and 27 of the housing 21 and the fixed portions 45 and 46 of the frame 3, which will be described later.

Wall portion 512 extends to the left from the rear end of wall portion 511. A first axial hole 513 is formed in the upper end of wall portion 512, and a first axial hole 514 is formed in the lower end of wall portion 512. The first axial holes 513 and 514 are each circular holes that penetrate in the front-to-back direction when viewed from the rear. The wall portion 512 has a pair of upper and lower notches 516 and 510 that are cut out from the left end of the wall portion 512 toward the right. In the vertical direction, the pair of notches 516 and 510 are formed between the first axial holes 513 and 514. The connecting portion between the wall portion 511 and the wall portion 512 has a hole 515 that penetrates in the front-to-back direction and is elongated in the left-to-right direction. In the vertical direction, the hole 515 is formed between the pair of notches 516 and 510.

[0022] The first clamping member 52 is a bent plate shape and has wall portions 521 and 522. Wall portion 521 is rectangular in right view. The front end portion 505 of wall portion 521 is located to the right of the central portion 504 in the front-rear direction of wall portion 521. Holes 527 and 530 are formed in the front end portion 505. Holes 528 and 529 are formed in the rear end portion of the central portion 504. Holes 527 to 530 are circular holes that penetrate from side to side in a right view, formed near the four corners of wall portion 521. Wall portion 522 extends to the right from the rear end of wall portion 521. The length of wall portion 522 in the left-right direction is longer than the length of wall portion 512 in the left-right direction. Wall portion 522 is positioned behind wall portion 512. A first elongated hole 523 is formed at the upper end of the wall portion 522, and a first elongated hole 524 is formed at the lower end of the wall portion 522. The first elongated holes 523 and 524 are each elongated in the first clamping direction C1, i.e., the left-right direction, and penetrate in the front-rear direction. The wall portion 522 further has circular holes 525 to 527 formed therein, which penetrate in the front-rear direction and are circular in shape when viewed from the rear. Hole 525 is formed to the right of the center of the wall portion 522 in the left-right direction, which is the longitudinal direction K of the base 4. Holes 526 and 527 are each formed to the left of the center of the wall portion 522 in the left-right direction. In the up-down direction, hole 525 is formed between holes 526 and 527. The wall portion 522 is equipped with a holder 740 below the first elongated hole 524. The holder 740 holds the harness of the power supply unit 39 of the air conditioner 2 by inserting it through it.

[0023] When fixing the first fixing part 5 to the first support column 961, the user positions the first clamping member 51 to the right of the first support column 961 and the first clamping member 52 to the left of the first support column 961. The user positions the wall portion 512 in front of the wall portion 522.

Similarly, the user inserts the first fixing member 542 from the rear into the first elongated hole 524 and the first shaft hole 514. The first elongated holes 523 and 524 allow for changes in the position of the first clamping member 52 relative to the first clamping member 51. The user adjusts the position of the first clamping members 51 and 52 in the first clamping direction C1 and temporarily fixes the position of the first clamping members 51 and 52 with the first fixing members 541 and 542. The arrangement of the first clamping members 51 and 52 with respect to the first support column 961 is adjusted so that the first clamping member 52 contacts the front surface of the first support column 961, the extension direction of the upper ends of the first clamping members 51 and 52 is parallel to the horizontal plane in the front-rear direction, and the extended surface of the wall portion 522 is parallel to the vertical direction. The user inserts the first bolt 531 from the right into the hole 517 in the wall portion 511 of the first clamping member 51 and the hole 527 in the wall portion 521 of the first clamping member 52. Similarly, the user inserts the first bolt 532 through hole 518 and hole 528, the first bolt 533 through hole 519 and hole 529, and the first bolt 534 through hole 520 and hole 530. The first bolts 531 and 534 are shorter than the first bolts 532 and 533.

[0024] As shown in Figure 7, the user tightens the first bolts 531 to 534 to clamp the first support column 961 with the first clamping members 51 and 52, thereby fixing the first fixing part 5 to the first support column 961. In the front-rear direction, the first support column 961 is located behind the first bolts 531 and 534 and in front of the first bolts 532 and 533. That is, in the front-rear direction, the first support column 961 is located between the first bolts 531 and 534 and the first bolts 532 and 533.

[0025] As shown in Figure 3, the first support member 7 supports the base 4 so that the base 4 is displaceable between a first position and a second position which is a position in which the base 4 is displaced relative to the first fixing part 5 and the second fixing part 6 with respect to the first position. In this embodiment, the first support member 7 is connected to the first fixing part 5 and the first end 47 of the base 4, respectively, and supports the base 4 so that it is rotatable in the first and second positions around an axis 71 extending in the axial direction J intersecting the longitudinal direction K of the base 4. The first support member 7 further supports the base 4 so that it is rotatable to a third position in which the opening degree relative to the first position is greater than that of the second position. As shown in state U12 in Figures 19 and 20, the first position in this embodiment is the position in the reference position where the longitudinal direction K of the base 4 is parallel to the imaginary line segment V connecting the first column fixing part 13 and the second column fixing part 14. In this embodiment, the imaginary line segment V is a line segment extending in the left-right direction, connecting the back surface of the first fixing part 5 and the back surface of the second fixing part 6. The first position is the position in the longitudinal direction K of the base 4 where the holding portion 41 is positioned between the first column fixing portion 13 and the second column fixing portion 14.

The elongated holes 735 and 736 are formed at the other end of the wall portion 732 in the longitudinal direction K of the base 4, and at positions separated from the shaft hole 734 in a direction that intersects the longitudinal direction K of the base 4. Specifically, the elongated hole 735 is formed in an arc shape centered on the shaft hole 734 when viewed from the rear, above and to the left of the shaft hole 734, and the elongated hole 736 is formed in an arc shape centered on the shaft hole 734 when viewed from the rear. In the vertical direction, the shaft hole 734 is located between the elongated holes 735 and 736. The elongated holes 735 and 736 are formed at positions corresponding to the holes 526 and 527 of the first fixing portion 5. The wall portion 731 extends rearward from the upper end of the wall portion 732, and the wall portion 733 extends rearward from the lower end of the wall portion 732. Holes 737 and 738 that penetrate in the vertical direction are formed in the wall portion 731. In the wall portion 731, a pair of front and rear holes 123 are formed to the left of the hole 737. In the wall portion 733, a hole 739 is formed that penetrates vertically at a position below the hole 737. The second member 72 is positioned between the wall portions 731 and 733.

[0027] The first member 73 is fixed to the back of the first fixing part 5. When fixing the first member 73 to the first fixing part 5, the user inserts the first fixing member 543 from the rear through the axial hole 734 of the first member 73 and the hole 525 of the first fixing part 5, inserts the second fixing member 545 from the rear through the elongated hole 735 of the first member 73 and the hole 526 of the first fixing part 5, and inserts the second fixing member 546 from the rear through the elongated hole 736 of the first member 73 and the hole 527 of the first fixing part 5. The user rotates the first member 73 around the first fixing member 543 to adjust the angle of the first member 73 relative to the first fixing part 5. The user uses a spirit level or the like placed on the top surface of the first member 73 to adjust the angle of the first member 73 relative to the first fixing part 5 so that the wall portion 731 is positioned horizontally. The user fastens the first fixing member 543 and the second fixing members 545 and 546 to fix the first member 73 to the back surface of the first fixing part 5.

[0028] As shown in Figure 3, the first support member 7 is positioned to the left of the first end of the first fixing part 5 in the second direction, i.e., the right end, in the left-right direction along the imaginary line segment V. The first member 73 of the first support member 7 is positioned inside both ends of the first fixing part 5 in the left-right direction, and the left-right extension of the first member 73 is inside the left-right extension of the first fixing part 5. In the up-down direction, the first elongated hole 523 is located above the upper surface of the first member 73, and the first elongated hole 524 is located below the bottom surface of the first member 73. The elongated holes 735 and 736 are located between the plate portions 721 and 723 of the second member 72.

[0029] As shown in Figures 2, 3, and 6, the second member 72 is a C-shaped bent plate member that is open to the right when viewed from the rear. The second member 72 comprises a wall portion 722 and plate portions 721 and 723, and can rotate relative to the wall portion 732 around the axis 71. The wall portion 722 faces the first adjustment member 171 which is fixed to the first end portion 47 of the base 4. Holes 751 that penetrate in the left-right direction are formed near the four corners of the wall portion 722. The second member 72 is fixed to the first adjustment member 171 by third fixing members 752 (see Figure 3) inserted through each of the holes 751. The plate portions 721 and 723 extend in a direction intersecting the axial direction J. Plate portion 721 extends to the right from the upper end of the wall portion 722, and plate portion 723 extends to the right from the lower end of the wall portion 722. A notch 724 is formed at the front end of plate portion 721, recessed to the rear. A notch 725 is formed at the front end of plate portion 723, recessed to the rear. The notches 724 and 725 are substantially the same in shape.

[0030] As shown in Figure 9, with the base 4 in the first position, the wall portion 732 is positioned in the portion where the notches 724 and 725 are formed, and the notches 724 and 725 face the wall portion 732. With the base 4 in the first position, in the front-rear direction, the front end of the second member 72 is located in front of the back surface of the first fixing portion 5. The notches 724 and 725 allow the base 4 to rotate to a position that is rotated from the position where the longitudinal direction K of the base 4 is parallel to the direction in which the extended surface of the wall portion 732 extends, toward the first position from the second position. When the base 4 is in the first position, the direction toward the first position from the second position is forward. That is, with the notches 724 and 725 provided, even if the base 4 rotates by a predetermined angle counterclockwise in a plan view from the position where the longitudinal direction K of the base 4 is parallel to the extended surface of the wall portion 732, the first member 73 does not interfere with the second member 72. The notches 724 and 725 contribute to reducing the situation in which the base 4 of the frame 3 attached to the vehicle 9 cannot be positioned in the first position due to twisting of the first support column 961 and the second support column 962 of the vehicle 9. The predetermined angle is set, for example, in the range of 0 to 5 degrees of the opening of the base 4 with respect to the first position.

[0031] As shown in Figure 6, holes 711 and 726 are formed in the plate portion 721, penetrating vertically. In the plate portion 723, a hole 727 is formed, penetrating vertically, at a position below hole 711. A cylindrical shaft 71 extends between the wall portions 731 and 733. Holes 711 and 727 communicate with the holes in the shaft 71. The second member 72 is positioned between the wall portions 731 and 733 such that hole 711 is located below hole 737 of the first member 73. A shaft member 74, extending vertically, is inserted through holes 737, 711, 727, and 739, respectively. The shaft member 74 comprises a body portion 741, a head portion 742, and a fixing portion 743. The head portion 742 is provided at the upper end of the shaft member 74. The diameter of the head portion 742 is larger than the diameter of the body portion 741 and the diameter of hole 737. The diameter of the body portion 741 is smaller than the diameter of the hole 737. The diameter of the fixing portion 743 is smaller than the diameter of the body portion 741. Screw threads are formed on the outer circumference of the fixing portion 743. Rings 744 and 746 are fitted onto the body portion 741. In the vertical direction, ring 744 is positioned between the wall portion 731 and the head portion 742 of the first member 73. In the vertical direction, ring 746 is positioned between the wall portion 733 of the first member 73 and the plate portion 723 of the second member 72. A nut 745 is fastened to the fixing portion 743 of the shaft member 74. This supports the second member 72 so that it can rotate around the shaft 71 relative to the first member 73.

[0032] The second locking mechanism 10 is used to restrict the base 4 from rotating beyond a predetermined range from each of the second and third positions. The second locking mechanism 10 is fixed to the upper surface of the first member 73 of the first support member 7. The second locking mechanism 10 comprises a second locking member 115, a second locking support 112, and a biasing member 116. The second locking member 115 is a cylindrical member that is long in the vertical direction. The upper end of the second locking member 115 is connected to a disc-shaped operating part 111. The diameter of the operating part 111 is larger than the diameter of the second locking member 115. The second locking support 112 is a plate-shaped member with a hole 113 that penetrates in the vertical direction. The lower end of the operating part 111 is inserted through the hole 113. The left end 114 of the second locking support 112 is bent downward from the surface in which the hole 113 is formed. A pair of front and rear holes 122 are formed in the left end 114. The second lock support portion 112 is fixed to the upper surface of the first member 73 by a pair of fixing members 121 inserted through a pair of holes 122 and a pair of front and rear holes 123 of the first member 73. The second lock support portion 112 supports the second lock member 115 so that it can be displaced in the vertical direction perpendicular to the longitudinal direction K of the base 4 between the second lock position and the second release position. The second lock position is located below the second release position. Specifically, in the vertical direction, the second lock position is the position where the lower end portion 117 of the second lock member 115 is below the upper surface of the plate portion 721. The second release position is the position in the vertical direction where the lower end portion 117 of the second lock member 115 abuts against the upper surface of the plate portion 721. The biasing member 116 biases the second lock member 115 in the direction from the second release position toward the second lock position, that is, downward. The lower end portion 117 of the second lock member 115 is inserted through the hole 738 of the first member 73 of the first support member 7. When the second locking member 115 is in the second release position, the lower end portion 117 of the second locking member 115 comes into contact with the plate portion 721 of the second member 72, pushing the plate portion 721 downward.

[0033] The second locking mechanism 10, when the second locking member 115 is in the second locking position, is adjacent to at least one of the base 4 and the first support member 7 in the second position, thereby restricting the base 4 from being displaced from the second position, or restricting the base 4 from being displaced from a third position that is different from the first and second positions. In the second locking mechanism 10 of this embodiment, when the base 4 is in the second or third position, the second locking member 115 is displaceable to the second locking position. As shown in state U13 of Figure 20, when the base 4 is in the second position and the second locking member 115 is in the second locking position, the lower end portion 117 of the second locking member 115 is inserted through the hole 726 of the second member 72 of the first support member 7 connected to the base 4, thereby restricting the base 4 from being displaced beyond a predetermined range from the second position. As shown in state U14 of Figure 20, in this embodiment, when the base 4 is in the third position and the second locking member 115 is in the second locking position, the lower end portion 117 of the second locking member 115 is inserted into the notch 725 of the second member 72 of the first support member 7, thereby restricting the base 4 from displacing beyond a predetermined range from the third position. That is, when the base 4 is in the second or third position, the second locking mechanism 10 moves the second locking member 115 to the second locking position, causing the second locking member 115 to enter the rotational trajectory P of the second member 72, thereby restricting the base 4 from displacing beyond a predetermined range from its current position. The predetermined range is defined by the size of the lower end portion 117 and the size of the hole 726 or notch 725.

[0034] The user can displace the second locking member 115 from the second locked position to the second released position by pushing the operating part 111 upward against the biasing force of the biasing member 116. When the second locking member 115 is in the second released position, the second locking mechanism 10 allows the second locking member 115 to move away from the hole 726 or notch 725 of the second member 72 of the first support member 7, which is in the second or third position, and allows the base 4 to be displaced from the second or third position. That is, when the base 4 is in the second or third position, the second locking mechanism 10 moves the second locking member 115 to the second released position, thereby retracting the second locking member 115 from within the rotational trajectory P of the second member 72 and allowing the base 4 to be displaced beyond a predetermined range from its current position.

[0035] As shown in Figures 8 to 14, the base 4 of the frame 3 comprises a main body 40, a shaft 43, a width adjustment mechanism 11, and a length adjustment mechanism 12. As shown in Figures 8 and 9, the main body 40 is formed by combining multiple structural members such as square pipes with a square cross-section. The bottom surface of the main body 40 has structural members 441 to 446. Structural members 441 to 444 each extend in the left-right direction. Structural members 441 to 444 are arranged in this order from front to back. Three fixing members 452 are inserted from below into structural members 442 and 443, respectively, at equal intervals in the left-right direction. Each fixing member 452 is inserted into the corresponding fixed part 17, fixing the air conditioner 2 to the holding part 41 from below. Structural members 445 and 446 each extend in the front-rear direction. Frame 445 is positioned in the front-rear direction between frames 441 and 444 and at the right end of the main body 40. Frame 445 connects to the right end of frame 442 and the right end of frame 443. Frame 446 is positioned in the front-rear direction between frames 441 and 444 and at the left end of the main body 40. Frame 446 connects to the left end of frame 442 and the left end of frame 443.

[0036] As shown in Figures 8 to 12, the main body 40 has structural members 411 to 421 that constitute the holding part 41. The bottom of the holding part 41 is made up of structural members 441 to 445. The holding part 41 is positioned towards the right, which is one side of the longitudinal direction K of the frame 3, and holds the air conditioner 2 in a position where one side of the longitudinal direction K1 of the housing 21, the side on which the air outlet 20 is provided, coincides with the right side, which is one side of the longitudinal direction K of the frame 3. Structural members 411 and 412 extend in the left-right direction. Structural members 413 to 415, 418, and 421 extend in the front-back direction. Structural members 416, 417, 419, and 420 extend in the up-down direction. The vertical lengths of structural members 416, 419, and 420 are approximately the same. The vertical length of frame 417 is shorter than the vertical length of frame 416. The lower end of frame 416 is connected to the upper right end of frame 441. The lower end of frame 419 is connected to the upper left side of the center of frame 441 in the left-right direction. The lower end of frame 420 is connected to the upper left side of the center of frame 444 in the left-right direction. The right end of frame 411 is connected to the left side of frame 416 at a predetermined vertical position. The left end of frame 411 is connected to frame 419 at a predetermined vertical position. The predetermined vertical position can be set appropriately according to the size of the device held by the holding part 41, and in this embodiment, it is a position below the center of frame 416 in the vertical direction. Frame 411 is located above frame 441. The upper right end of frame 412 connects to the lower end of frame 417. The left end of frame 412 connects to the right side of frame 420 at the same vertical position as frame 411. Frame 412 is located above frame 444. The front end of frame 413 connects to the rear of frame 416 at the same vertical position as frame 411.

The rear end of frame 415 connects to the front of the lower end of frame 420. Frame 414 is located above frame 415.

[0037] The front end of frame 418 is connected to the upper rear end of frame 416. The rear end of frame 418 is connected to the upper front end of frame 417. Frame 418 is located above frame 413. A pair of front and rear fixing parts 45 are formed on the upper surface of frame 418. Each of the pair of fixing parts 45 is a screw hole for fastening a screw that fixes a fastener 49 to the holding part 41. The front end of frame 421 is connected to the upper rear end of frame 419. The rear end of frame 421 is connected to the upper front end of frame 420. Frame 421 is located above frame 414. A pair of front and rear fixing parts 46 are formed on the upper surface of frame 421. Each of the pair of fixing parts 46 is a screw hole for fastening a screw that fixes a fastener 50 to the holding part 41. The fixing parts 45 and 46 fix the fixed parts 26 and 27 of the air conditioner 2 to the holding part 41. In this embodiment, the base 4 has fixing parts 45 and 46 corresponding to the fixed parts 26 and 27, respectively.

[0038] The main body 40 has structural members 461 to 465 that constitute the connecting part 42. The connecting part 42 is provided in the second direction of the holding part 41. In this embodiment, the connecting part 42 is connected to the end of the holding part 41 in the second direction, that is, the left end. The bottom of the connecting part 42 is made up of structural members 441 to 444 and 446. Structural members 461 and 462 extend in the left-right direction. The left-right length of structural members 461 and 462 is shorter than the left-right length of structural members 411 and 412. Structural member 465 extends in the front-rear direction. The front-rear length of structural member 465 is approximately the same as the front-rear length of structural members 413 and 414. Structural members 463 and 464 extend in the up-down direction. The vertical lengths of structural bodies 463 and 464 are shorter than the vertical lengths of structural bodies 416, 419, and 420. The lower end of structural body 463 connects to the upper left end of structural body 441. The lower end of structural body 464 connects to the upper left end of structural body 444. The right end of structural body 461 connects to the left side of structural body 419 at the same vertical position as structural body 411. The lower left end of structural body 461 connects to the upper end of structural body 463. Structural body 461 is located above structural body 441. The right end of structural body 462 connects to the left side of structural body 420 at the same vertical position as structural body 411. The lower left end of structural frame 462 connects to the upper end of structural frame 464. The front end of structural frame 465 connects to the rear left end of structural frame 461 at the same vertical position as structural frame 411. The rear end of structural frame 465 connects to the front left end of structural frame 462 at the same vertical position as structural frame 411. Structural frame 465 is located above structural frame 446.

[0039] As shown in Figures 7 and 10, the length H2 of the connecting portion 42 in the vertical direction is shorter than the length H1 of the holding portion 41. In the vertical direction, the upper end of the holding portion 41 is located above the upper end of the first fixing portion 5 and the upper end of the second fixing portion 6. In the vertical direction, the lower end of the holding portion 41 is located at approximately the same position as the lower end of the first fixing portion 5 and the lower end of the second fixing portion 6. In the longitudinal direction K of the base 4, the center M2 of the holding portion 41 is located in the first direction, i.e., to the right, of the center M3 of the base 4 and the center M1 of the main body portion 40. In the longitudinal direction K of the base 4, the length L1 of the main body portion 40 is longer than half the length L3 of the base 4, and the length L2 of the holding portion 41 is longer than half the length L1 of the main body portion 40.

[0040] As shown in Figure 15, the shaft 43 is cylindrical and extends along the longitudinal direction K of the frame 3. The right end of the shaft 43 is fixed to a rectangular plate member 191 when viewed from the right side. The central part of the shaft 43 is inserted through and fixed to a rectangular plate member 192 when viewed from the right side. The shaft 43 is fixed to the connecting part 42 of the main body 40 via the width adjustment mechanism 11 and the plate members 191 and 192. The shaft 43 forms the second end 48 of the base 4.

[0041] The width adjustment mechanism 11 can adjust the position of the base 4 relative to the first column fixing part 13 and the second column fixing part 14 in the width direction W, which is perpendicular to the longitudinal direction K of the base 4 and the longitudinal direction F1 of the first column 961. The width direction W is perpendicular to the axial direction J, that is, the vertical direction. The width adjustment mechanism 11 includes a first adjustment member 171 and second adjustment members 172 and 173. The first adjustment member 171 is fixed to the first end 47 of the base 4 so as to be able to change the position of the base 4 in the width direction W relative to the first column fixing part 13. The first adjustment member 171 is rectangular in shape when viewed from the right side and is fixed to the right end of the main body part 40. The first adjustment member 171 has a plurality of round holes 181 arranged in the width direction W. The plurality of round holes 181 are arranged in two rows, one above the other, at equal intervals in the front-to-back direction. The width adjustment mechanism 11 fixes the position of the base 4 in the width direction W at the first end 47 of the base 4 by inserting the third fixing member 752 through each of the holes 751 in the second member 72 of the first support member 7 and one of the corresponding round holes 181 among the plurality of round holes 181.

[0042] The second adjustment members 172 and 173 are fixed to the second end 48 of the base 4 so as to be able to change the position of the base 4 in the width direction W relative to the second column fixing part 14, or the position of the holding part 41 of the base 4 in the width direction W relative to the second column fixing part 14 is changed by changing the position of the second end 48 of the base 4 in the width direction W relative to the holding part 41. In this embodiment, the second adjustment members 172 and 173 change the position of the holding part 41 of the base 4 in the width direction W relative to the second column fixing part 14 by changing the position of the second end 48 of the base 4 in the width direction W relative to the holding part 41. The second adjustment member 172 is a rectangular plate that is long in the front-rear direction and is fixed to the left side of the frame 414, 415, 419, 420 of the holding part 41 within the main body 40. The second adjustment member 172 has a plurality of circular holes 182 arranged in the width direction W. The plurality of circular holes 182 are arranged in two rows, upper and lower, at equal intervals in the front-rear direction, similar to the plurality of circular holes 181. The second adjustment member 172 fixes the position of the shaft 43 in the width direction W by inserting the third fixing member 174 through each of the holes formed near the four corners of the plate member 191 and one of the corresponding round holes 182. Similarly, the second adjustment member 173 is a rectangular plate that is long in the front-rear direction and is fixed to the left side of the frame 446, 463 to 465 of the connecting part 42 within the main body 40. The second adjustment member 173 has a plurality of round holes 183 arranged in the width direction W and an elongated hole 193 that is long in the width direction W. Similar to the plurality of round holes 182, the plurality of round holes 183 are arranged in two rows, upper and lower, at equal intervals in the front-rear direction. The elongated hole 193 is through which the shaft 43 fixed to the plate member 192 is inserted. The second adjustment member 173 fixes the position of the shaft 43 in the width direction W by inserting the third fixing member 174 through each of the holes formed near the four corners of the plate member 192 and one of the corresponding round holes 183 among the plurality of round holes 183.

[0043] In Figure 15, state U4 shows the base 4 positioned furthest forward relative to the first column fixing part 13 and the second column fixing part 14; state U5 shows the base 4 positioned one hole 181 further back than its furthest rearward position relative to the first column fixing part 13 and the second column fixing part 14; and state U6 shows the base 4 positioned furthest rearward relative to the first column fixing part 13 and the second column fixing part 14. In states U4 to U6, the longitudinal direction K, the vertical position, and the horizontal position of the base 4 are the same. In each of states U4 to U6, the base 4 can be displaced between the first and second positions.

[0044] As shown in Figure 16, the length adjustment mechanism 12 can change the length of the base 4 in the longitudinal direction K. The length of the base 4 can be changed by the length adjustment mechanism 12. The length adjustment mechanism 12 includes a shaft 43 that can change the amount of protrusion from the holding portion 41 in the longitudinal direction K of the base 4. The base 4 has a connecting portion 42 on the second direction side. The shaft 43 is connected to the connecting portion 42 via the width adjustment mechanism 11, and the amount of protrusion from the connecting portion 42 in the second direction, i.e., to the left, can be changed. The shaft 43 has a cylindrical first member 431 and a second member 432 inserted through the first member 431, and the length L3 (see Figure 10) of the base 4 in the longitudinal direction K can be adjusted by adjusting the amount of overlap between the first member 431 and the second member 432 in the longitudinal direction K. In this embodiment, the length adjustment mechanism 12 does not change the length L1 of the main body portion 40 of the base 4 in the longitudinal direction K, nor the length L2 of the holding portion 41 of the base 4 in the longitudinal direction K. The length adjustment mechanism 12 is provided with a fixing portion 433 at the left end of the first member 431. The length adjustment mechanism 12 fixes the position of the second member 432 relative to the first member 431 by a screw provided on the fixing portion 433.

[0045] State U7 in Figure 16 shows a state in which the overlap amount in the longitudinal direction K between the first member 431 and the second member 432 is increased compared to state U8, and state U9 shows a state in which the overlap amount in the longitudinal direction K between the first member 431 and the second member 432 is decreased compared to state U8. The base 4 is expandable and contractible in the longitudinal direction K of the base 4 by the length adjustment mechanism 12. In states U7 to U9, the longitudinal direction K of the base 4 is the same for all of them. In each of states U7 to U9, the base 4 can be displaced between the first position and the second position.

[0046] As shown in Figure 17, the second column fixing part 14 fixes the second end 48 of the base 4 in the second direction opposite to the first direction to the second support column 962 of the vehicle 9. The second column fixing part 14 is fixed to the lower part of the second support column 962 below the ramp 992. In the vertical direction, the upper end of the second column fixing part 14 is in approximately the same position as the upper end of the first column fixing part 13. The second column fixing part 14 comprises a second fixing part 6, a second support member 82, and a first locking mechanism 8.

[0047] The second fixing part 6 is connected to the second support member 82 and fixed to the second support column 962 of the vehicle 9. The second fixing part 6 is a clamp that clamps and fixes the second support column 962 in a second clamping direction C2 that intersects the longitudinal direction F2 of the second support column 962, and has a pair of second clamping members 61 and 62. In this embodiment, the second clamping direction C2 is the left-right direction. The second clamping member 61 is positioned to the left of the second support column 962, and the second clamping member 62 is positioned to the right of the second support column 962.

[0048] The second clamping member 61 has a wall portion 611 and a wall portion 612. The wall portion 611 is rectangular in shape when viewed from the right side. Except for some components such as the holes 515, the wall portion 611 has a left-right symmetrical structure to the wall portion 511 of the first clamping member 51. The upper end portion 601 and the lower end portion 602 of the wall portion 611 are each located to the right of the vertical center portion 603 of the wall portion 611. In the left-right direction, the positions of the upper end portion 601 and the lower end portion 602 of the wall portion 611 are approximately the same. Holes 617 and 618 are formed in the upper end portion 601 of the wall portion 611. Holes 619 and 620 are formed in the lower end portion 602 of the wall portion 511. Holes 617 to 620 are each circular in shape, penetrating in the left-right direction when viewed from the left side, and are formed near the four corners of the wall portion 611. The wall portion 612 extends to the right from the rear end of the wall portion 611. A second shaft hole 613 is formed at the upper end of the wall portion 612, penetrating in the front-rear direction. A notch 614 is formed in the wall portion 612, cut out from the right end to the left. The second shaft hole 613 is located above the notch 614.

[0049] The second clamping member 62 is a bent plate shape and has wall portions 621 and 622. Wall portion 621 is rectangular in right-side view. Wall portion 621 has a left-right symmetrical configuration with wall portion 521 of the first clamping member 52. The front end portion 604 of wall portion 621 is located to the left of the central portion 605 in the front-rear direction of wall portion 621. Holes 627 and 630 are formed in the front end portion 604. Holes 628 and 629 are formed in the rear end portion of the central portion 605. Holes 627 to 630 are circular holes that penetrate in the left-right direction in left-side view and are formed near the four corners of wall portion 621. Wall portion 622 extends to the left from the rear end of wall portion 621. The left-right length of wall portion 622 is longer than the left-right length of wall portion 612. Wall portion 622 is positioned behind wall portion 612. A second elongated hole 626 is formed in the wall portion 622, penetrating in the front-to-back direction. The second elongated hole 626 is elongated in the second clamping direction C2, i.e., in the left-to-right direction. The wall portion 622 has circular holes 624, 625, and 627 formed in the rear view, penetrating in the front-to-back direction. Hole 625 is formed to the right of the center of the wall portion 622 in the left-to-right direction, which is the longitudinal direction K of the base 4. Holes 624 and 627 are each formed to the left of the center of the wall portion 622 in the left-to-right direction. In the up-to-down direction, hole 625 is formed between holes 624 and 627.

[0050] When fixing the second fixing part 6 to the second support column 962, the user positions the second clamping member 61 to the left of the second support column 962 and the second clamping member 62 to the right of the second support column 962. The user positions the wall portion 612 in front of the wall portion 622. The user inserts the second fixing member 941 from the rear into the second elongated hole 626 of the wall portion 622 of the second clamping member 62 and the second axial hole 613 of the wall portion 612 of the second clamping member 61. The second elongated hole 626 allows for changes in the position of the second clamping member 62 relative to the second clamping member 61. The user adjusts the position of the second clamping members 61 and 62 in the second clamping direction C2 by positioning the second support column 962 and temporarily fixes the positions of the second clamping members 61 and 62 with the second fixing member 941. The arrangement of the second clamping members 61 and 62 relative to the second support column 962 is adjusted such that the second clamping member 62 contacts the front surface of the second support column 962, the extension direction of the upper ends of the second clamping members 61 and 62 is parallel to the horizontal plane in the front-rear direction, and the extended surface of the wall portion 622 is parallel to the vertical direction. The user inserts the second bolt 631 from the left into the hole 617 in the wall portion 611 of the second clamping member 61 and the hole 627 in the wall portion 621 of the second clamping member 62. Similarly, the user inserts the second bolt 632 into the holes 618 and 628, the second bolt 633 into the holes 620 and 630, and the second bolt 634 into the holes 619 and 629. The second bolts 631 and 633 are shorter than the second bolts 632 and 634. As shown in Figure 7, the user tightens the second bolts 631 to 634 to clamp the second support column 962 with the second clamping members 61 and 62, thereby fixing the second fixing part 6 to the second support column 962. In the front-rear direction, the second support column 962 is located behind the second bolts 631 and 633 and in front of the second bolts 632 and 634. That is, in the front-rear direction, the second support column 962 is located between the second bolts 631 and 633 and the second bolts 632 and 634.

[0051] As shown in Figures 17 and 18, the second support member 82 is connected to the second fixing part 6 and supports the second end 48 of the base 4, i.e., the left end of the shaft 43, when the base 4 is in the first position. The second support member 82 is a plate-shaped member that is bent into a C-shape in plan view with the rear end open. The second support member 82 includes wall portions 821 to 823. Wall portion 821 faces the back surface of the second fixing part 6. The wall portion 821 has an axial hole 832, elongated holes 838, 839, and hole 831 that penetrate in the front-rear direction. The axial hole 832 is formed at one end of the wall portion 821 in the longitudinal direction K of the base 4. Specifically, the axial hole 832 is located to the right of the center of the wall portion 821 in the left-right direction. The axial hole 832 is formed at a position corresponding to the hole 625 of the second fixing part 6. The elongated holes 838 and 839 are formed at the other end of the wall portion 821 in the longitudinal direction K of the base 4, and at positions separated from the shaft hole 832 in a direction that intersects the longitudinal direction K of the base 4. Specifically, the elongated hole 838 is formed in an arc shape centered on the shaft hole 832 when viewed from the rear, above and to the left of the shaft hole 832, and the elongated hole 839 is formed below and to the left of the shaft hole 832. In the vertical direction, the shaft hole 832 is located between the elongated holes 838 and 839. The elongated holes 838 and 839 are formed at positions corresponding to the holes 624 and 627 of the second fixing portion 6, respectively. The head of the second fixing member 941, which was used to temporarily fix the second clamping members 61 and 62, is placed in hole 831.

[0052] Wall portion 822 extends rearward from the right end of wall portion 821, and wall portion 823 extends rearward from the left end of wall portion 821. A pair of upper and lower holes 826 and 825 that penetrate in the left-right direction are formed in wall portion 822. A notch 824 recessed forward from the rear end is formed in wall portion 822. The notch 824 is formed below the pair of holes 826 and 825. A pair of upper and lower holes 829 and 830 that penetrate in the left-right direction are formed in wall portion 823. A notch 828 recessed forward from the rear end is formed in wall portion 823. The notch 828 is formed below the pair of holes 829 and 830. The left end of the shaft 43 of the base 4 in the first position is positioned in the notches 824 and 828. The second support member 82 supports the left end of the shaft 43 of the base 4 in the first position through the notches 824 and 828.

[0053] The second support member 82 is fixed to the second fixing part 6. When fixing the second support member 82 to the second fixing part 6, the user inserts the first fixing member 942 from the rear through the axial hole 832 of the second support member 82 and the hole 625 of the second fixing part 6, the second fixing member 943 from the rear through the elongated hole 838 of the second support member 82 and the hole 624 of the second fixing part 6, and the second fixing member 944 from the rear through the elongated hole 839 of the second support member 82 and the hole 627 of the second fixing part 6. The user rotates the second support member 82 with respect to the second fixing part 6, with the first fixing member 942 as the pivot point, to adjust the angle of the second support member 82 relative to the second fixing part 6. The user uses a spirit level or the like to adjust the angle of the second support member 82 relative to the second fixing part 6 so that the upper surface of the wall part 821 is positioned horizontally. The user fastens the first fixing members 942 to 944 to fix the second support member 82 to the back of the second fixing part 6. As shown in Figure 3, the second support member 82 is positioned inside both ends of the first fixing part 5 in the direction along the imaginary line segment V (see Figure 9) connecting the first column fixing part 13 and the second column fixing part 14. In other words, the extension range of the second support member 82 in the left-right direction is inside the extension range of the second fixing part 6 in the left-right direction.

[0054] The first locking mechanism 8 is fixed to the second fixing part 6. The first locking mechanism 8 comprises a first locking member 81 and a second support member 82. The first locking member 81 is displaceable between a first locking position and a first release position. The second support member 82 functions as a first locking support that supports the first locking member 81. The first locking member 81 is a plate member bent in a C-shape with the front open in plan view. The first locking member 81 is positioned between the wall portions 822 and 823 of the second support member 82. The first locking member 81 comprises wall portions 811 to 813 and an operating part 820. Wall portion 811 extends in the axial direction J and faces wall portion 821 of the second support member 82. A hole 810 is formed in wall portion 811 that penetrates in the front-rear direction. Wall portion 812 extends forward from the right end of wall portion 811. A hole 808 and an L-shaped elongated hole 816 are formed in wall portion 812 in left side view. The wall portion 813 extends forward from the left end of the wall portion 811. The wall portion 813 has a hole 819 and an L-shaped elongated hole 817 when viewed from the left side. The holes 808, 819, and elongated holes 816 and 817 each penetrate in the left-right direction.

[0055] The shaft 85 extends in the left-right direction and is inserted through the hole 819. The right end of the shaft 85 is positioned between the wall portions 812 and 813, and the fixing member 827 is inserted from the right. The shaft 85 supports the upper end of the biasing member 86. The biasing member 86 is a coil spring. The lower end of the biasing member 86 is supported by a fixing member 87 that extends in the front-rear direction. The fixing member 87 is fixed to the second support member 82. The biasing member 86 biases the first locking member 81 in the direction from the first release position to the first locking position. The shaft 83 extends in the left-right direction and is inserted through the elongated holes 816 and 817 and the hole 829. The right end of the shaft 83 is positioned between the wall portions 822 and 823, and the fixing member 840 is inserted from the right. The shaft 84 extends in the left-right direction and is inserted through the elongated holes 816 and 817 and the hole 830. The right end of shaft 84 is positioned between wall portions 822 and 823, and a fixing member 850 is inserted through it from the right. The first locking member 81 is supported by the second support member 82 so as to be displaceable in the vertical direction along the elongated holes 816 and 817 through which shafts 83 and 84 are inserted.

[0056] The wall portion 812 has a contact surface 815, and the wall portion 813 has a contact surface 818. The contact surfaces 815 and 818 contact the shaft 43 of the base 4 in the first position when the first locking member 81 is in the first locked position. The contact surfaces 815 and 818 are inclined as the base 4 moves from the first position to the second position, and as the first locking member 81 moves from the first release position to the first locked position. In this embodiment, the side of the base 4 moving from the first position to the second position in the reference position is the rear. The side of the first locking member 81 moving from the first release position to the first locked position is downward. In other words, the contact surfaces 815 and 818 are inclined downward as they move towards the rear. In a left side view, the angle between the wall portion 811 and the contact surfaces 815 and 818 is acute. The operating portion 820 extends rearward from the upper end of the wall portion 811. The operating unit 820 is operated by the user when moving the first locking member 81 from the first locked position to the first unlocked position.

[0057] As shown in state U10 in Figures 14 and 18, when the first locking member 81 is in the first locking position, the first locking member 81 enters the rotational trajectory Q of the base 4 when the base 4 is displaced from the first position to the second position, thereby restricting the base 4 from being displaced from the first position to the second position. In other words, when the first locking member 81 is in the first locking position, the first locking member 81 is adjacent to the shaft 43 of the base 4 in the first position, thereby restricting the base 4 from being displaced from the first position to the second position. The rotational trajectory Q is an arc shape centered on the axis 71 in plan view. When the first locking member 81 is in the first locking position, the first locking member 81 is biased downward by the biasing member 86. Therefore, the first locking member 81 applies its own weight and the biasing force from the biasing member 86 to the shaft 43, suppressing the shaft 43 from wobbling. The lower surface of the first locking member 81 is a contact surface 815, 818 that is inclined along the outer circumference of the shaft 43, so that the contact surfaces 815, 818 can be reliably brought into contact with the shaft 43. The lower ends of the contact surfaces 815, 818 are located below the axis of the shaft 43. Therefore, the first locking member 81 can simultaneously press the shaft 43 downward and restrict the shaft 43 from rotating clockwise in a plan view.

[0058] As shown in state U11, the first locking mechanism 8 allows the first locking member 81 to retract from the rotation trajectory Q and the base 4 to be displaced from the first position to the second position when the first locking member 81 is in the first release position. In other words, the first locking mechanism 8 allows the first locking member 81 to separate from the base 4 in the first position and the base 4 to be displaced from the first position to the second position when the first locking member 81 is in the first release position. When the user displaces the base 4 from the first position to the second or third position, they operate the operating part 820 to displace the first locking member 81 from the first lock position to the first release position against the biasing force of the biasing member 86. The notches 824 and 828 that contact the lower outer circumference of the shaft 43 are inclined slightly downward towards the rear. For this reason, when the first locking member 81 is displaced from the first lock position to the first release position, the user can easily displace the shaft 43 rearward. The lower ends of the elongated holes 816 and 817 of the first locking member 81 extend forward. Therefore, by displacing the first locking member 81 along the elongated holes 816 and 817, the user can maintain the first locking member 81 in the first release position against the biasing force of the biasing member 86.

[0059] The rotational position of the base 4 will be described with reference to Figures 19 and 20. As shown in state U12 in Figures 19 and 20, when the base 4 is in the first position, the extension direction of the virtual line segment V and the longitudinal direction K of the base 4 are parallel. When the base 4 is in the first position, the shaft 43 is restricted by the first locking mechanism 8 from rotating beyond a predetermined range from the first position. When the base 4 is in the first position, the right end of the first support member 7 and the right end of the base 4 are located to the left of the right end of the first fixing part 5. The left end of the holding part 41 of the base 4 is located to the right of the left end of the driver's seat 92. The left end of the shaft 43 is located slightly to the left of the left end of the first locking mechanism 8. In plan view, the main body 40 is contained within the extension range of the vehicle body 91.

[0060] As shown in state U13, when the base 4 is in the second position, the base 4 is rotated 145 degrees clockwise in a plan view relative to when the base 4 is in the first position. At this time, the second locking member 115 of the second locking mechanism 10 is displaceable from the second release position to the second locking position, and the lower end portion 117 of the second locking member 115 fits into the hole 726 of the second member 72 of the first support member 7. As a result, the lower end portion 117 of the second locking member 115 enters the rotation trajectory P of the second member 72, and the base 4 is restricted from rotating beyond a predetermined range from the second position. In a plan view, the base 4 does not overlap with the vehicle body 91. The extension range in a plan view when the base 4 is in the first position and the extension range in a plan view when the base 4 is in the second position do not overlap and are separated from each other. Therefore, the user can easily perform tasks such as attaching and detaching the air conditioner 2 to the holding part 41, and inspecting the vehicle 9 or the air conditioner 2.

[0061] As shown in state U14, when the base 4 is in the third position, the base 4 is rotated 185 degrees clockwise in a plan view relative to when the base 4 is in the first position. At this time, the second locking member 115 of the second locking mechanism 10 is displaceable from the second release position to the second locking position, and the lower end portion 117 of the second locking member 115 fits into the notch 725 of the second member 72 of the first support member 7. As a result, the lower end portion 117 of the second locking member 115 enters the rotation trajectory P of the second member 72, and the base 4 is restricted from rotating counterclockwise beyond a predetermined range from the third position. When the base 4 is in the third position, the wall portion 722 of the second member 72 abuts against the wall portion 732 of the first member 73. As a result, the base 4 is restricted from rotating counterclockwise beyond a predetermined range in a plan view from the third position. In this embodiment, the predetermined ranges for the second and third positions are set to less than 1 degree in the opening of the base 4 relative to the first position. The second locking member 115 is fixed to the upper surface of the first support member 7. Therefore, the user can easily rotate the base 4 from the first position to the second or third position and operate the second locking member 115 while standing behind the vehicle body 91. Depending on the shape of the vehicle body 91, when the base 4 is in the second position, the vehicle body 91 and the base 4 may overlap in a plan view. In contrast, when the base 4 is in the third position, the frame 3 can reduce the possibility of the base 4 overlapping with the vehicle body 91 in a plan view. Therefore, the user can easily perform tasks such as attaching and detaching the air conditioner 2 to the holding part 41, and inspecting the vehicle 9 or the air conditioner 2.

[0062] A modified example of the frame 103 will be described with reference to Figures 21 and 22. In Figure 21, the same reference numerals are used for components similar to those in the frame 3 of the above embodiment. As shown in Figure 21, the modified frame 103 differs from the frame 3 of the above embodiment in that it includes a first column fixing part 107 instead of the first column fixing part 13, and a second column fixing part 108 instead of the second column fixing part 14. The first column fixing part 107 fixes the first end 47 in the first direction along the longitudinal direction K of the base 4 to the first support column 963 of the vehicle 9. The second column fixing part 108 fixes the second end 48 in the second direction along the longitudinal direction K of the base 4 to the second support column 964 of the vehicle 9. The first column fixing part 107 differs from the frame 3 of the above embodiment in that it includes a first fixing part 105 instead of the first fixing part 5, and the second column fixing part 108 differs from the frame 3 of the above embodiment in that it includes a second fixing part 106 instead of the second fixing part 6. The following describes the first fixing part 105 and the second fixing part 106, which differ from the frame 3 of the above embodiment. The first support column 963 and the second support column 964 have different cross-sectional shapes from the first support column 961 and the second support column 962 of the above embodiment, but their longitudinal directions are the same.

[0063] The first fixing section 105 and the second fixing section 106 are suitable for attaching the frame 103 to the first support column 963 and the second support column 964 of a vehicle 9, where the length of the first fixing section 105 and the second fixing section 106 in the front-rear direction must be smaller than that of the first fixing section 5 and the second fixing section 6. Since the first fixing section 105 and the second fixing section 106 have a left-right symmetrical configuration with some exceptions, the configuration of the first fixing section 105 will be explained, and the explanation of the second fixing section 106 will be simplified.

[0064] As shown in Figure 22, the first fixing portion 105 has a pair of first clamping members 150 and 160 that clamp and fix the first support column 963 in a first clamping direction C1 that intersects the longitudinal direction F1 of the first support column 963. The first clamping member 150 is positioned to the right of the first support column 963, and the first clamping member 160 is positioned to the left of the first support column 963.

[0065] The first clamping member 160 is a bent plate member having a first bent portion 145, a first pressing wall portion 164, and a wall portion 162. The first bent portion 145 has a wall portion 163 facing the front surface of the first support column 963, and a wall portion 161 extending rearward from the left end of the wall portion 163. The wall portion 161 is continuous with the wall portion 163. The wall portion 161 extends in a direction perpendicular to the wall portion 163. The wall portion 161 has a pair of upper and lower holes 147 and 148. The pair of holes 147 and 148 are circular holes in the right side view that penetrate in the left-right direction. When the first fixing portion 105 is fixed to the first support column 963, the wall portion 161 and the wall portion 163 of the first bent portion 145 each come into contact with the first support column 963. Specifically, wall portion 163 abuts against the front surface of the first support column 963, and wall portion 161 abuts against the left side surface of the first support column 963. The first pressing wall portion 164 is connected to the first bending portion 145 and is positioned at a distance from the first support column 963. The first pressing wall portion 164 extends rearward from the right end of wall portion 163. The length of the first pressing wall portion 164 in the front-rear direction is shorter than the length of the wall portion 161 opposite to the first pressing wall portion 164 in the front-rear direction. The first pressing wall portion 164 has first insertion portions 165 to 167 through which the first bolts 175 to 177 are inserted in the first clamping direction C1. The first insertion portions 165 to 167 are arranged at equal intervals in the vertical direction. The front-rear positions of the first insertion portions 165 to 167 are set, for example, taking into consideration the shape of the first support column 963. In this embodiment, the first insertion portions 165 to 167 are formed at a position where the width of the first support column 963 is maximized in the left-right direction, with each of the wall portions 161 and 163 of the first bent portion 145 in contact with the first support column 963. The wall portion 162 has the same configuration as the wall portion 522. Specifically, the wall portion 162 has first elongated holes 168, 169 and holes 141 to 143, corresponding to the first elongated holes 523, 524 and holes 525 to 527.

[0066] The first clamping member 150 is a bent plate member having a first pressed wall portion 151 and a wall portion 152. The first pressed wall portion 151 is rectangular in right-side view and is positioned between the first pressed wall portion 164 and the first support column 963 in the first clamping direction C1. The first pressed wall portion 151 has a protrusion 153 and a pair of upper and lower holes 154 and 155. The protrusion 153 projects forward from the front end of the first pressed wall portion 151. The vertical position of the protrusion 153 is near the vertical center of the first pressed wall portion 151. The pair of holes 154 and 155 are circular in right-side view and penetrate in the left-right direction. The pair of holes 154 and 155 are formed at positions corresponding to a pair of holes 147 and 148 of the first clamping member 160. The first pressed wall portion 151 is pressed against the first support column 963 by first bolts 175 to 177 inserted through first insertion portions 165 to 167. The wall portion 152 has the same configuration as the wall portion 512 of the first clamping member 51. Specifically, the wall portion 152 has first axial holes 156, 159 and notches 157, 158, which correspond to the first axial holes 513, 514 and notches 516, 510.

[0067] When fixing the first fixing part 105 to the first support column 963, the user positions the first clamping member 150 to the right of the first support column 963 and the first clamping member 160 to the left of the first support column 963. The user positions the wall portion 152 in front of the wall portion 162. In the first clamping direction C1, the first pressed wall portion 151 is positioned between the first support column 963 and the first pressing wall portion 164. The wall portion 163 abuts against the front surface of the first support column 963, and the wall portion 161 abuts against the left side surface of the first support column 963. The user inserts the first fixing member 186 from the rear into the first elongated hole 168 of the wall portion 162 of the first clamping member 160 and the first axial hole 156 of the wall portion 152 of the first clamping member 150. The user inserts the first fixing member 187 from the rear into the first elongated hole 169 in the wall portion 162 of the first clamping member 160 and the first axial hole 159 in the wall portion 152 of the first clamping member 150. The first elongated holes 168 and 169 allow for changes in the position of the first clamping member 160 relative to the first clamping member 150. The user adjusts the position of the first clamping members 150 and 160 in the first clamping direction C1 relative to the first support column 963 and temporarily fixes the positions of the first clamping members 150 and 160 with the first fixing members 186 and 187. The user inserts the first bolt 184 from the right into the hole 154 in the first pressed wall portion 151 of the first clamping member 150 and the hole 147 in the wall portion 161 of the first clamping member 160. Similarly, the user inserts the first bolt 185 through the holes 155 and 148 from the right. The first bolts 184 and 185 are located behind the first support column 963. The user inserts the first bolts 175 to 177 through the first insertion parts 165 to 167. The first pressed wall portion 151 is pressed against the first support column 963 by the first bolts 175 to 177 inserted through the first insertion parts 165 to 167. As a result, the first support column 963 is clamped in the first clamping direction C1 by the first pressed wall portion 151 and the wall portion 161. When the first fixing portion 105 is fixed to the first support column 963, no fixing members such as bolts are placed in front of the first support column 963. Therefore, the size of the first fixing portion 105 in the front-rear direction can be reduced compared to the first fixing portion 5.

[0068] Since holes 141 to 143 are formed in the wall portion 162, when the first support member 7 is fixed to the first fixing portion 105, the user inserts the first fixing member 188 from the rear through the axial hole 734 of the first member 73 and the hole 141 of the first fixing portion 105, inserts the second fixing member 189 from the rear through the elongated hole 735 of the first member 73 and the hole 142 of the first fixing portion 105, and inserts the second fixing member 190 from the rear through the elongated hole 736 of the first member 73 and the hole 143 of the first fixing portion 105. The user rotates the first member 73 around the first fixing member 188 to adjust the angle of the first member 73 relative to the first fixing portion 105 and fixes it in place.

[0069] The second fixing portion 106 is symmetrical to the first fixing portion 105, except for some configurations including a configuration for attaching the first locking mechanism 8 to the second fixing portion 106, and has a pair of second clamping members 250, 260. The second clamping member 250 includes a second bent portion 245 and a second pressing wall portion 264. The second bent portion 245 has two continuous wall portions 261, 263, and when the second column fixing portion 108 is fixed to the second support column 964, each of the two wall portions 261, 263 abuts against the second support column 964. The second pressing wall portion 264 is connected to the second bent portion 245, separated from the second support column 964, and has a second insertion portion 265 through which the second bolt 275 is inserted in the second clamping direction C2. The second clamping member 260 has a second pressed wall portion 251, and when the second column fixing portion 14 is fixed to the second support column 964, the second bolt 285 is inserted from the left through the hole 254 in the second pressed wall portion 251 and the hole 247 in the wall portion 261. The second bolt 284 is located behind the second support column 964. In the second clamping direction, the second pressed wall portion 251 is positioned between the second pressed wall portion and the second support column 964 and is pressed against the second support column 964 by the second bolt 275. The second clamping member 260 has a wall portion 262 similar to the wall portion 622 of the second clamping member 62 in the above embodiment, and the second clamping member 250 has a wall portion 252 similar to the wall portion 612 of the second clamping member 61 in the above embodiment.

[0070] A modified example of the first locking mechanism 608 will be described with reference to Figures 23 and 24. In Figures 23 and 24, components similar to those of the first locking mechanism 608 in the above embodiment are given the same reference numerals, and their descriptions are simplified or omitted. As shown in Figures 23 and 24, the first locking mechanism 608 is provided on the frame 3 of the above embodiment instead of the first locking mechanism 8, and is fixed to the second fixing part 6. The first locking mechanism 608 comprises a first locking member 88, a second support member 89, and a third locking mechanism 870. The first locking member 88 is displaceable between a first locking position and a first release position. The second support member 89 functions as a first locking support part that supports the first locking member 88. The first locking member 88 is a C-shaped bent plate member with an open front in plan view, and comprises wall portions 811, 861, 862, and an operating part 820. Wall portion 861 extends forward from the right end of wall portion 811, and wall portion 862 extends forward from the left end of wall portion 811. Wall portion 861 has elongated holes 863, 864, and hole 865 formed in it, which are elongated in the vertical direction when viewed from the left side. In the vertical direction, the extension range of elongated hole 863 is longer than the extension range of elongated hole 864. Wall portion 862 has an elongated hole 866 similar to elongated hole 863. Elongated holes 863, 864, 866, and hole 865 each penetrate in the left-right direction.

[0071] The second support member 89 is connected to the second fixing part 6 and supports the left end of the shaft 43 when the base 4 is in the first position. The second support member 89 includes wall portions 821, 881, and 882. Wall portion 881 extends rearward from the right end of wall portion 821 and has a contact surface 815, and wall portion 882 extends rearward from the left end of wall portion 821 and has a contact surface 818. In addition to the holes 826, 825 and notches 824 similar to those in the above embodiment, a hole 883 is formed in wall portion 881. In the front-rear direction, hole 883 is located in front of holes 826 and 825, and in the up-down direction, hole 883 is located between holes 826 and 825. In wall portion 882, holes 829, 830 and notches 828 similar to those in the above embodiment are formed.

[0072] Shaft 83 extends in the left-right direction and is inserted through elongated holes 863, 866 and hole 829. The right end of shaft 83 is positioned between wall portions 881 and 882, and a fixing member 840 is inserted from the right. Shaft 84 extends in the left-right direction and is inserted through elongated holes 863, 866 and hole 830. The right end of shaft 84 is positioned between wall portions 881 and 882, and a fixing member 850 is inserted from the right. The first locking member 88 is supported by the second support member 89 so as to be displaceable in the vertical direction along the elongated holes 863 and 866 through which shafts 83 and 84 are inserted.

[0073] The third locking mechanism 870 detachably fixes the position of the first locking member 88 in both the first locking position and the first release position. The third locking mechanism 870 comprises a pin 872, an operating part 871, a biasing member 873, and a support member 874. The pin 872 is cylindrical and extends in the left-right direction. The operating part 871 is disc-shaped when viewed from the right side and is fixed to the right end of the pin 872. The diameter of the operating part 871 is larger than the diameter of the pin 872. The biasing member 873 is a coil spring that is externally fitted onto the pin 872 to the left of the support member 874. The biasing member 873 biases the pin 872 to the left. The support member 874 is a plate-shaped member bent into a C shape with the left side open when viewed from above, and supports the pin 872 so that it can move in a left-right direction perpendicular to the downward direction from the first release position to the first locking position. The operating section 871 is located to the right of the support member 874. The lower end of the support member 874 is bent into an L-shape when viewed from the rear and extends parallel to the wall portion 881 of the second support member 89. The support member 874 is fixed to the right side of the second support member 89 and above the notch portion 824 by a fixing member 875 inserted through the lower end of the support member 874.

[0074] As shown in state U15 of Figure 24, when the first locking member 88 is in the first locking position, the first locking mechanism 608 enters the rotational trajectory Q of the base 4 when the base 4 is displaced from the first position to the second position, thereby restricting the base 4 from being displaced from the first position to the second position. When the first locking member 88 is in the first locking position, the pin 872 of the third locking mechanism 870 is inserted through the hole 883 and the elongated hole 864. As a result, the pin 872 restricts the first locking member 88 from moving beyond a predetermined range from the first locking position. The predetermined range is defined by the vertical length of the elongated hole 864 and the diameter of the pin 872. The vertical length of the elongated hole 864 is greater than 1.1 times the diameter of the pin 872 and less than 2 times the diameter of the pin 872. The first locking member 88 adds its own weight to the shaft 43, suppressing rattling of the shaft 43.

[0075] As shown in state U16, the first locking mechanism 608 allows the first locking member 88 to retract from the rotation trajectory Q and the base 4 to be displaced from the first position to the second position when the first locking member 88 is in the first release position. The first release position is located above the first locking position. When the user displaces the base 4 from the first position to the second or third position, they operate the operating unit 871 to remove the pin 872 from the elongated hole 864, and then operate the operating unit 820 to displace the first locking member 88 from the first locking position to the first release position. After displacing the first locking member 88 from the first locking position to the first release position, the user inserts the pin 872 of the third locking mechanism 870 into the holes 883 and 865. This allows the user to maintain the state in which the first locking member 88 is in the first release position.

[0076] In the above embodiment, the frame 3, base 4, first fixing part 5, second fixing part 6, first support member 7, first locking mechanism 8, vehicle 9, and second locking mechanism 10 are examples of the frame, base, first fixing part, second fixing part, first support member, first locking mechanism, vehicle, and second locking mechanism of the present invention. The holding part 41, shaft 43, first end part 47, second end part 48, shaft 71, first locking member 81, second support member 82, biasing member 86, second locking member 115, and second locking support part 112 are examples of the holding part, shaft, first end part, second end part, shaft, first locking member, second support member, biasing member, second locking member, and second locking support part of the present invention. The plate parts 721 and 723 are examples of plate parts of the present invention. The notches 724 and 725 are examples of notches of the present invention. The wall part 732 is an example of a wall part of the present invention. The contact surfaces 815 and 818 are examples of contact surfaces of the present invention. The second support member 82 is an example of the first lock support part of the present invention. The first support column 961 and the second support column 962 are examples of the first support column and the second support column of the present invention, respectively. The first clamping direction C1, the second clamping direction C2, the longitudinal direction K3, the longitudinal direction F1, the longitudinal direction F2, and the axial direction J are examples of the first clamping direction, the second clamping direction, the first longitudinal direction, the second longitudinal direction, the third longitudinal direction, and the axial direction of the present invention, respectively. The rotation trajectory Q is an example of the first trajectory. The rotation trajectory P is an example of the second and third trajectories. The virtual line segment V is an example of the virtual line segment of the present invention. The modified pin 872 is an example of the pin of the present invention.

[0077] The frame 3 of the above embodiment is fixed to an open-cabin type vehicle 9 having a first support column 961 and a second support column 962. The frame 3 comprises a base 4, a first fixing part 5, a second fixing part 6, a first support member 7, and a first locking mechanism 8. The base 4 has a holding part 41 for holding an object. The first fixing part 5 is fixed to the first support column 961 of the vehicle 9. The second fixing part 6 is fixed to the second support column 962 of the vehicle 9. The first support member 7 is connected to each of the base 4 and the first fixing part 5, and supports the base 4 so that it can move between a first position and a second position which is a position that is displaced relative to the first fixing part 5 and the second fixing part 6 with respect to the first position. The first locking mechanism 8 has a first locking member 81 that moves between a first locked position and a first unlocked position. The first locking mechanism 8, when the first locking member 81 is in the first locking position, prevents the base 4 from moving from the first position to the second position by entering the rotational trajectory Q of the base 4 when the base 4 moves from the first position to the second position. The first locking mechanism 8, when the first locking member 81 is in the first release position, allows the first locking member 81 to retract from the rotational trajectory Q, allowing the base 4 to move from the first position to the second position. The first support member 7 of the frame 3 contributes to reducing the possibility that the frame 3 may interfere with vehicle maintenance work or work to hold objects by displacing the base 4 between the first and second positions. The first locking mechanism 8 of the frame 3 contributes to preventing the base 4 from moving from the first position to the second position. The first locking mechanism 8 of the frame 3 contributes to reducing malfunctions caused by the base 4 moving from the first position to the second position when the user does not intend it.

[0078] The first support member 7 is connected to the first fixing part 5 and to the first end 47 of the base 4 in the first direction along the longitudinal direction K of the base 4, and supports the base 4 so as to be rotatable around an axis 71 extending in the axial direction J perpendicular to the longitudinal direction K of the base 4. The frame 3 is connected to the second fixing part 6 and includes a second support member 82 that supports the second end 48 of the base 4 in the second direction opposite to the first direction when the base 4 is in the first position. The frame 3 can secure the amount of movement of the second end 48 of the base 4 with a simpler configuration than a configuration in which the base 4 can be displaced between the first and second positions by sliding the base 4. The power supply unit 39 of the air conditioner 2 extends from the right side of the air conditioner 2 on the axis 71 side in the longitudinal direction K and is inserted into the first elongated hole 524 of the first fixing part 5, so that the harness can be arranged around the first support column 961 near the axis 71, and the frame 3 can be rotated with the harness connected to the vehicle 9.

[0079] The first locking mechanism 8 is fixed to the second fixing part 6, and when the first locking member 81 is in the first locking position, the first locking member 81 enters the rotation trajectory Q and restricts the base 4 from rotating from the first position to the second position. When the first locking member 81 is in the first release position, the first locking mechanism 8 retracts from the rotation trajectory Q and allows the base 4 to rotate from the first position to the second position. The first locking mechanism 8 of the frame 3 can restrict the rotation of the base 4 in the first position when the first locking member 81 enters the rotation trajectory Q, so it can stably restrict the rotation of the base 4 in the first position compared to when the first locking member 81 is provided near the shaft 71.

[0080] The base 4 is connected to the holding portion 41 and has a shaft 43 extending from the holding portion 41 in a second direction. The second support member 82 supports the shaft 43 when the base 4 is in the first position. The rotation trajectory Q is the trajectory of the shaft 43 when the base 4 is displaced from the first position to the second position. The first locking mechanism 8 of the frame 3 only needs to support the shaft 43 when the base 4 is in the first position, so it can be made into a relatively simple configuration compared to when the second end portion 48 of the base 4 is a component other than the shaft 43, such as the main body portion 40.

[0081] The first locking member 81 has contact surfaces 815 and 818 that contact the shaft 43 of the base 4 when it is in the first locked position. The contact surfaces 815 and 818 are inclined toward the side from the first unlocked position toward the first locked position as the base 4 moves toward the second position from the first position. The first locking member 81 of the frame 3 can stably contact the shaft 43 when the base 4 is in the first position.

[0082] The first position is the position where the longitudinal direction K of the base 4 is parallel to the imaginary line segment V connecting the first fixing part 5 and the second fixing part 6. The first support member 7 is fixed to the first fixing part 5 and has a wall portion 732 extending in a direction parallel to the axial direction J, and plate portions 721 and 723 extending in a direction intersecting the axial direction J and rotating relative to the wall portion 732 about an axis 71. The plate portions 721 and 723 have notches 724 and 725 formed therein that allow the base 4 to rotate to a position rotated toward the first position from the second position than the position where the longitudinal direction K of the base 4 is parallel to the extended surface of the wall portion 732. The frame 3 can rotate the base 4 to a position where the second end portion 48 of the base 4 can be supported by the second support member 82, even when the positions of the first support column 961 and the second support column 962 are twisted with respect to the rotation direction of the base 4.

[0083] The first locking mechanism 8 has a second support member 82 that supports the first locking member 81 so that it can be displaced in the axial direction J between a first locking position and a first release position. The frame 3 makes it easier to move the first locking member 81 between the first release position and the first locking position compared to the case where the first locking member 81 is not supported by the second support member 82.

[0084] The first locking mechanism 8 has a biasing member 86 that biases the first locking member 81 in the direction from the first release position toward the first locking position. The frame 3 prevents the first locking member 81 from moving from the first locking position toward the first release position even when a force is applied in the direction of displacement of the base 4.

[0085] The first support member 7, which is at least one of the base 4 and the first support member 7, has a plate portion 721 that displaces together with the base 4. The frame 3 is equipped with a second locking mechanism 10 having a second locking member 115 that displaces to a second locking position and a second release position. When the second locking member 115 is in the second locking position and the base 4 is in the second position, the second locking mechanism 10 prevents the base 4 from displacing from the second position to the first position by allowing the second locking member 115 to enter the rotational trajectory P of the plate portion 721 when the base 4 displaces from the second position to the first position. When the second locking member 115 is in the second release position, the second locking mechanism 10 allows the second locking member 115 to retract from the rotational trajectory P, and permits the base 4 to displace from the second position to the first position. The frame 3 can maintain the state in which the base 4 is positioned in the second position when the base 4 is in the second position, thus improving the convenience of the user of the frame 3 for tasks such as vehicle maintenance work and tasks involving holding objects.

[0086] The second locking mechanism 10 includes a second locking support portion 112 that supports the second locking member 115 so that it can be displaced between the second locking position and the second unlocking position in a direction perpendicular to the longitudinal direction K of the base 4. The frame 3 facilitates the operation of moving the second locking member 115 between the second unlocking position and the second locking position.

[0087] The first support member 7 is connected to the first fixing part 5 and to the first end 47 of the base 4 in the first direction along the longitudinal direction K of the base 4, and supports the base 4 so as to be rotatable about an axis 71 that extends in the axial direction J perpendicular to the longitudinal direction K of the base 4. The second locking mechanism 10 is located on the first support member 7. Because the second locking mechanism 10 is located around the axis 71 of the frame 3, the user can easily access the second locking member 115.

[0088] The first support member 7 is connected to the first fixing part 5 and to the first end 47 of the base 4 in the first direction along the longitudinal direction K of the base 4, and supports the base 4 so as to be rotatable about an axis 71 extending in the axial direction J perpendicular to the longitudinal direction K of the base 4. The frame 3 has a second support member 82 and a second locking mechanism 10. The second support member 82 is connected to the second fixing part 6 and supports the second end 48 of the base 4 in the second direction opposite to the first direction when the base 4 is in the first position. The first support member 7, which is at least one of the base 4 and the first support member 7, has a plate portion 721 that displaces together with the base 4. The frame 3 has a second locking mechanism 10. The second locking mechanism 10 has a second locking member 115 that displaces between a second locked position and a second unlocked position. The second locking mechanism 10, when the second locking member 115 is in the second locking position and the base 4 is in the second position, enters the rotation trajectory P of the plate portion 721 when the base 4 rotates from the second position to the first position, thereby restricting the base 4 from rotating from the second position to the first position. The second locking mechanism 10, when the base 4 is in the second position and the second locking member 115 is in the second release position, retracts the second locking member 115 from the rotation trajectory P, thereby allowing the base 4 to rotate from the second position to the first position. The second locking mechanism 10, when the second locking member 115 is in the second locking position and the base 4 is in the third position, where the opening degree relative to the reference is greater than that of the second position, enters the rotation trajectory P of the plate portion 721 when the base 4 rotates from the third position to the second position, thereby restricting the base 4 from rotating from the third position to the second position. The second locking mechanism 10, when the base 4 is in the third position and the second locking member 115 is in the second release position, retracts the second locking member 115 from the rotation trajectory P, allowing the base 4 to rotate from the third position to the second position. The support frame 3 can reduce the possibility of the base 4 and the vehicle body 91 overlapping in a plan view compared to when the base 4 cannot rotate to the third position. The support frame 3 can improve the convenience of the user of the support frame 3 for tasks such as vehicle maintenance work and holding objects, both when the base 4 is in the second position and when it is in the third position.

[0089] The first fixing part 5 is a clamp that clamps and fixes the first support column 961 in a first clamping direction C1 that intersects the longitudinal direction F1 of the first support column 961. The second fixing part 6 is a clamp that clamps and fixes the second support column 962 in a second clamping direction C2 that intersects the longitudinal direction F2 of the second support column 962. The frame 3 is designed to facilitate the process of fixing the frame 3 to the vehicle 9.

[0090] The base 4 is extendable and retractable in the longitudinal direction K of the base 4. The frame 3 can be fixed to each of multiple vehicles 9, each having a different distance between the first support column 961 and the second support column 962.

[0091] In the longitudinal direction K of the base 4, the center M2 of the holding portion 41 is positioned in a first direction along the longitudinal direction K of the base 4 or in a second direction opposite to the first direction, relative to the center M3 of the base 4. In the frame 3, the holding portion 41 of the base 4 is positioned to one side in the longitudinal direction K of the base 4, so the degree to which the air conditioning system 1 obstructs the driver's view when checking behind the vehicle 9 on the side where the holding portion 41 is not positioned, i.e., to the left of the driver's seat 92, can be reduced compared to conventional designs. In this embodiment, as shown in Figure 7, the driver of the vehicle 9 can easily check behind the vehicle to the left of the driver's seat 92.

[0092] The modified first locking mechanism 608 has a pin 872 that is inserted into the first locking member 88 in a direction perpendicular to the direction in which the first locking member 88 is displaced from the first locking position to the first release position, and the pin 872 restricts the displacement of the first locking member 88 from the first locking position to the first release position. Therefore, the modified first locking mechanism 608 helps the user maintain the state in which the first locking member 88 is positioned in the first locking position. The first locking mechanism 608 can suppress the displacement of the first locking member 88 when the user does not intend it. The third locking mechanism 870 of the first locking mechanism 608 is provided on the right side of the second support member 89, which is between the first fixing part 5 and the second fixing part 6 in the left-right direction. The first locking mechanism 608 is less likely to interfere with the driving and operation of the vehicle 9 compared to the case in which the third locking mechanism 870 is provided on the left side of the second support member 89.

[0093] The present invention is not limited to the above embodiments, and various modifications are possible. The mounting direction of the frame 3 to the vehicle 9 is not limited to the direction in which the longitudinal direction K of the frame 3 is in the left-right direction of the vehicle 9, but may be, for example, the longitudinal direction K of the frame 3 may be in the front-rear direction of the vehicle 9. In other words, the frame 3 may be mounted between the column 951 and the first support column 961. The open-cabin type vehicle 9 to which the frame 3 is attached is not limited to a forklift, but may be, for example, a golf cart, construction equipment (small excavator), etc.

[0094] The air conditioner 2 attached to the vehicle 9 by the frame 3 is not limited to a spot cooler, but may also be a heater, dehumidifier, air purifier, mist sprayer, etc. The internal configuration of the housing 21 may be appropriately changed depending on the type of air conditioner 2. Instead of the air conditioner 2, the frame 3 may hold vehicle-related items such as a spare battery for at least one of the vehicle 9 and air conditioner 2, a pen, slips of paper, and the driver's belongings such as drinks, etc. The arrangement of the air outlet 20, power supply unit 39, and tank 24 of the air conditioner 2 relative to the housing 21 may be appropriately changed. For example, the air outlet 20 may be provided on the front, back, right side, left side, or bottom of the housing 21. If the power supply unit 39 is a power battery, the harness may be omitted. If the power supply unit 39 is a power harness, the power harness may be directly connected to a portable power supply (battery), for example, or connected to a portable power supply via an AD / DC converter. The power supply unit 39 may be a harness extending from the front, left side, top, bottom, or rear of the housing 21. The power supply unit 39 may be omitted.

[0095] The method of holding the air conditioner 2 on the frame 3 is not limited to the case where the air conditioner 2 is held on the upper surface of the holding part 41 as in the above embodiment. For example, the air conditioner 2 may be directly attached to the holding part 41 of the base 4 by a rubber band that surrounds it. The air conditioner 2 does not have to be fixed to the base 4 via the fasteners 49 and 50, and may be directly fixed to the base 4 by a fixing member inserted through the fixed parts 26 and 27 of the air conditioner 2, for example. The number, shape, and arrangement of at least one of the fixed parts 26 and 27, the fixing parts 45 and 46, the fasteners 49 and 50, and the fixing member 452 may be changed as appropriate. Some of the fasteners 49 and 50 and the fixing member 452 may be omitted.

[0096] The configurations of the first fixing part 5 and the second fixing part 6 may be modified as appropriate. For example, the shapes of the pair of first clamping members 51 and 52, and the pair of second clamping members 61 and 62 are not limited to a flat plate shape, but may be other shapes. At least one of the pair of first clamping members 51 and 52, and the pair of second clamping members 61 and 62 may be provided with a resin material such as rubber for anti-slip purposes. The pair of first clamping members 51 and 52 do not need to have at least one of the first axial holes 513 and 514, or the first elongated holes 523 and 524. The first fixing part 5 may be a U-shaped fixing device having a shape that follows the three sides of the first support column 961 instead of the pair of first clamping members 51 and 52, or a band that is wrapped around and fixed to the first support column 961, or a fixing device such as a bolt that is inserted through the first support column 961. The second fixing part 6 may be a U-shaped fixing device having a shape that conforms to the three sides of the second support column 962, a band that is wrapped around and fixed to the second support column 962, or a fixing device such as a bolt that is inserted through the second support column 962, instead of the pair of second clamping members 61 and 62. The pair of second clamping members 61 and 62 do not need to have at least one of the second shaft hole 613 or the second elongated hole 626. The number, arrangement, length, and type of the first bolts 531 to 534 used in the first fixing part 5 may be changed as appropriate. The number of first bolts 531 to 534 may be 1 to 3 or 5 or more. Similarly, the number, arrangement, length, and type of the second bolts 631 to 634 used in the second fixing part 6 may be changed as appropriate. The number of second bolts 631 to 634 may be 1 to 3 or 5 or more. The frame 3 may be fixed directly to the first column 961 with bolts or the like by fixing the first support member 7 to the first support column 961, in which case the first support member 7 functions as the first fixing part. The method for setting the virtual line segment V may be appropriately changed depending on the configuration of the first column fixing part 13, the second column fixing part 14, the first fixing part 5, and the second fixing part 6. For example, the method for setting the virtual line segment V may be a line segment connecting the front end of the first column fixing part 13 and the front end of the second column fixing part 14.

[0097] The configuration of the base 4 may be modified as appropriate. The base 4 may have a structure in which the main body 40 and the shaft 43 are integrated. The base 4 may omit at least one of the connecting part 42, the shaft 43, the width adjustment mechanism 11, and the length adjustment mechanism 12. If the base 4 does not have a shaft 43, the left end of the main body 40 of the base 4 may be supported by the second support member 82. The shaft 43 may not be able to extend or retract in the longitudinal direction K of the base 4. The base 4 may have a configuration in which the main body 40 extends or retracts in the longitudinal direction K of the base 4. The shaft 43 may be provided in the first direction of the main body 40 within the longitudinal direction K of the base 4, that is, on the side of the shaft 71. The connecting part 42 may be provided in the second direction of the holding part 41 and does not have to be directly connected to the holding part 41. The shaft 43 was supported at two points on the connecting portion 42 in the longitudinal direction K of the base 4, but it may be supported at one point, three or more points, or on the surface of a plate extending parallel to the bottom of the main body portion 40. The first end of the shaft 43 may be supported on the main body portion 40 at a position away from the holding portion 41 in the second direction.

[0098] The position of the base 4 in the width direction W relative to the first fixing part 5 and the second fixing part 6 may be immovable. The configuration of the width adjustment mechanism 11 may be changed as appropriate. The width adjustment mechanism 11 may be fixed to the second end of the main body part 40, i.e., the left end, so as to be able to change the position of the base 4 in the width direction W relative to the second column fixing part 14. The configuration for changing the position of the first fixing part 5 and the second fixing part 6 in the width direction W may be provided in addition to the base 4. For example, the position of the back surface of the first fixing part 5 that connects to the first support member 7 may be movable in the front-rear direction. The position of the first fixing part 5 that connects to the first support member 7 may be changed in the front-rear direction by connecting to the first support member 7 via a spacer. The position of the back surface of the second fixing part 6 that connects to the second support member 82 may be movable in the front-rear direction. The position of the second fixing part 6 that connects to the second support member 82 may be changed in the front-rear direction by connecting to the second support member 82 via a spacer.

[0099] The base 4 may be formed in part or in whole by combining structural members, or in part or in whole by combining plate members. The cross-sectional shape of part or all of the structural members used in the base 4 may be any shape, such as a polygon or a circle. The number, length, longitudinal direction, and arrangement of the structural members of the base 4 may be changed as appropriate. In the longitudinal direction K of the base 4, the center M2 of the holding portion 41 may coincide with the center M3 of the base 4, or it may be located to the left of the center M3.

[0100] The first support member 7 is connected to the base 4 and the first fixing part 5, and supports the base 4 so that it can move between a first position and a second position which is a position displaced relative to the first fixing part 5 and the second fixing part 6 with respect to the first position. For example, the first support member 7 may be configured to allow the base 4 to move parallel to the first fixing part 5 and the second fixing part 6 in any direction such as the front-rear direction, the up-down direction, and the left-right direction. Specifically, the first support member 7 may be provided so that the base 4 can move horizontally on the base plate, and the base 4 may be displaced between a first position on the base plate and a second position which is pulled out by a predetermined amount in any direction. The first support member 7 may be provided with a hinge that rotatably supports the base 4, so that the base 4 can rotate between the first position and the second position. The first support member 7 may also be able to displace the base 4 between the first position and the second position by rail and link mechanism, etc. The first position, second position and third position may be changed as appropriate.

[0101] The first support member 7 may be shaped so that it does not interfere with the second member 72 even when the base 4 is rotated by a predetermined angle counterclockwise in a plan view from a position where the longitudinal direction K of the base 4 is parallel to the extended surface of the wall portion 732, by reducing the size of the plate portions 721 and 723 of the first support member 73 without the notches 724 and 725. Alternatively, the first support member 7 may be shaped so that it interferes with the second member 72 when the base 4 is rotated by a predetermined angle counterclockwise in a plan view from a position where the longitudinal direction K of the base 4 is parallel to the extended surface of the wall portion 732, by reducing the size of the plate portions 721 and 723 of the first support member 73 without the notches 724 and 725.

[0102] The first support member 7 does not necessarily have to have at least one of the axial holes 734 and the elongated holes 735 and 736 formed therein. The position and shape of the axial holes 734 and the elongated holes 735 and 736 in the wall portion 732 may be changed as appropriate. For example, the axial holes 734 and the elongated holes 735 and 736 may be formed on the same line in the axial direction J, or on the same line in the longitudinal direction K of the base 4. The first support member 7 may be connected to any of the left side, front, top, and bottom surfaces of the first fixing portion 5, depending on the arrangement of the first support column 961 in the vehicle 9. One of the elongated holes 735 and 736 may be formed in relation to the axial hole 734, or three or more elongated holes including the elongated holes 735 and 736 may be formed.

[0103] The configuration of the first locking mechanism 8 may be appropriately modified depending on the configuration of the first support member 7 and the base 4. The shaft 71 of the first support member 7 may be provided on the left side of the frame 3. In other words, the first direction may be to the left. The shaft 71 may extend in a left-right direction parallel to the longitudinal direction K of the frame 3. In this case, the shaft 71 may be connected to the front, back, top, or bottom surface of the base 4. If a hole extending in the vertical direction is formed at the left end of the shaft 43, the first locking member 81 may have a first lock position when it enters the hole and a first release position when it retracts from the hole. The first lock position and the first release position may be appropriately modified depending on the configuration of the first locking member 81 and the method of locking the base 4 by the first locking member 81. In other words, the direction in which the first locking member 81 is displaced from the first lock position to the first release position with respect to the rotation trajectory Q of the base 4 may be appropriately modified. For example, the first locking member 81 may be displaceable between a first locking position where it enters the rotation trajectory Q of the base 4 and a first release position where it is retracted from the rotation trajectory Q by rotating horizontally around an axis 71 extending in the axial direction J. The first locking mechanism 8 may be provided on the first support member 7. Specifically, the first locking mechanism 8 may have a second locking member 115 of the second locking mechanism 10, and the plate portion 721 of the second member 72 may be provided with a hole that allows the second locking member 115 of the second locking mechanism 10 to move to the second locking position when the base 4 is in the first position. The shape, size, and arrangement of the contact surfaces 815 and 818 may be changed as appropriate. The first locking member 81 may have a single contact surface that is long in the left-right direction and connected to the contact surfaces 815 and 818. The first locking member 81 may contact the shaft 43 with a surface that extends vertically.

[0104] The configuration of the second support member 82 as the first lock support part may be changed as appropriate. The second support member 82 may be provided with guide parts such as elongated holes and grooves that guide the first lock member 81 to the first lock position and the first release position, in which case the first lock member 81 should have guided parts such as protrusions and shafts that are inserted into the guide parts. The biasing member 86 may be omitted as appropriate, for example, when the weight of the first lock member 81 of the first lock mechanism 8 is sufficiently heavy. The biasing member 86 may be a biasing member such as a torsion spring or a leaf spring. The first lock mechanism 8 may electrically displace the first lock member 81 to the first lock position and the first release position. The first lock member 81 may be a fastener such as a bolt that detachably fixes the second end 48 of the base 4 to the second fixing part 6. The first lock member 81 may be a band member that fixes the second end 48 of the base 4 to the second fixing part 6. In these cases, the second end 48 of the base 4 is supported by the second fixing part 6. The frame 3 may have a second support member 82 that supports the shaft 43 and a first lock support part that supports the first lock member 81 as separate components. The shapes of the notches 824 and 828 of the second support member 82 may be changed as appropriate. The third lock mechanism 870 may not have holes 865 and may not be able to hold the first lock member 88 in the first release position. The shapes and arrangement of the holes 864 and 865 may be changed as appropriate.

[0105] The configuration of the second locking mechanism 10 may be appropriately modified according to the configuration of the first support member 7 and the base 4. The second locking mechanism 10 may be displaceable from the second release position to the second locking position only when the base 4 is in the second position. The second locking mechanism 10 may be displaceable from the second release position to the second locking position at each of three or more positions, including the second and third positions, where the base 4 is located. The second locking mechanism 10 may be fixed to the base 4, and the position where the second locking member 115 enters the rotational trajectory P of the restricting part provided on the first member 73 or the first fixing part 5 may be defined as the second locking position, and the position where it retracts from the trajectory may be defined as the second release position. The second locking mechanism 10 may be omitted. The biasing member 116 may be omitted as appropriate. The second locking mechanism 10 may electrically displace the second locking member 115 between the second locking position and the second release position. Various fixing members may be appropriately modified and may include bolts and nuts, various screws, etc. The above modifications may be combined within a range that is not contradictory.
