  The 1st bending part 213b is a bending part by which the edge part by the side of the attachment part 4b in the expansion | extension direction of the 1st reinforcement component 21a was bent by the inclination part 132a side of the 1st leg component 13a. The second bent portion 214b is a bent portion in which the side portion of the first reinforcing component 21a is bent toward the inclined portion 132a of the first leg component 13a. That is, the second bent portion 214b is a first region sandwiching the fastening hole 215 in the extending direction of the first reinforcing component 21a in the region on the end portion side on the attachment portion 4b side in the extending direction of the first reinforcing component 21a. A bent portion is provided on the side opposite to the side where the bent portion 213b is provided, and the side portion of the flat portion 211 is bent toward the inclined portion 132a side of the first leg component 13a.

  The protruding dimension 213c from which the first bent part 213a protrudes from the leg attachment surface 216 may be a dimension that can stop the rotation of the first leg part 12a in the temporarily fixed state by the first bent part 213a. The protrusion dimension 213c from which the first bent portion 213b protrudes from the leg attachment surface 216 may be a dimension that can stop the rotation of the inclined portion 132a of the first leg component 13a in the temporarily fixed state by the first bent portion 213b. That's fine.

  The protruding dimension 214c from which the second bent portion 214a protrudes from the leg attachment surface 216 may be a dimension that can stop the rotation of the first leg component 12a in the temporarily fixed state by the second bent portion 214a. The protrusion dimension 214c from which the second bent portion 214b protrudes from the leg attachment surface 216 is a dimension that can stop the rotation of the inclined portion 132a of the first leg component 13a in the temporarily fixed state by the second bent portion 214b. That's fine.

  As described above, in the temporarily fixed state, the tightening of the screw component is loose, and the inclined portion 122a of the first leg component 12a rotates about the central axis of the screw component with respect to the first reinforcing component 21a. Is possible. In this case, for example, the inclined portion 122a can rotate to the first rotation position where the side surface position of the inclined portion 122a is indicated by the first side surface position 24a in FIG. The first rotational position is such that the portion vertically above the fastening hole 125 in the first leg part 12a is the fastening hole 125 in the first leg part 12a and the fastening hole in the first reinforcing part 21a. This is a rotational position rotated to the center side of the first reinforcing component 21 a in the extending direction of the first reinforcing component 21 a than 215.

  Further, the inclined portion 122a can rotate, for example, to a second rotational position where the side surface position of the inclined portion 122a is indicated by the second side surface position 24b in FIG. The second rotational position is such that the part vertically below the fastening hole 215 in the first leg part 12a is the fastening hole 125 in the first leg part 12a and the fastening hole in the first reinforcing part 21a. This is a rotational position rotated to the center side of the first reinforcing component 21 a in the extending direction of the first reinforcing component 21 a than 215.

  The first bent part 213a and the second bent part 214a are bent toward the inclined part 122a of the first leg part 12a, so that the first leg part 12a in the device installation stand 1 in the temporarily fixed state is provided. However, when the inclined part 122a rotates about the central axis of the bolt 5 attached to the attaching part 4a, the inclined part 122a comes into contact with the first bent part 213a or the second bent part 214a, thereby the first bent part. The rotation of the first leg part 12a is restricted by the role of the obstacle that obstructs the rotation of the 213a or the second bent portion 214a.

  An interval 22a that is an interval between the first bent portion 213a and the second bent portion 214a in the extending direction of the first reinforcing component 21a is larger than a width 22b that is a width of the inclined portion 122a of the first leg component 12a. Is done. The inclined portion 122a of the first leg part 12a and the first reinforcing part 21a are coaxial with the fastening hole 125 of the first leg part 12a and the fastening hole 215 of the first reinforcing part 21a. And are fixed by bolts 5 and nuts 6.

  Therefore, as shown in FIG. 5, in the extending direction of the first reinforcing component 21 a, between the side surface of the first leg component 12 a facing the first bent portion 213 a and the first bent portion 213 a, and the second A gap 23 is formed between the side surface of the first leg part 12a facing the bent portion 214a and the second bent portion 214a. Then, by adjusting the gap dimension 22c, which is the dimension of the gap 23 in the extending direction of the first reinforcement component 21a, the appropriateness of the first leg component 12a with respect to the first reinforcement component 21a in the temporarily fixed state described above. It is possible to limit the rotation range from a simple posture, that is, the rotation range of the first leg part 12a from the vertical direction to an arbitrary range.

  Further, the first bent portion 213a and the second bent portion 214a are arranged so as to sandwich the inclined portion 122a of the first leg part 12a through the gap 23. Thereby, in the assembly of the apparatus installation stand 1, the first bent portion 213a and the second bent portion 214a align the inclined portion 122a of the first leg component 12a and the first reinforcing component 21a. And the screw fastening operation between the inclined portion 122a of the first leg part 12a and the first reinforcing part 21a becomes easy. Thereby, in the apparatus installation stand 1, the assembly property of the apparatus installation stand 1 is improved.

  In particular, when the fan mounting dimension 31d is large, the distance between the first leg part 12a and the second leg part 12b, which is the distance between the pair of legs 11, is long, and the first leg The workability of the screw fastening work between the body part 12a and the second leg part 12b and the first reinforcing part 21a is likely to deteriorate. However, in the apparatus installation stand 1, the first bent part 213a and the second bent part 214a are positioned when the inclined part 122a of the first leg part 12a and the first reinforcing part 21a are aligned. Since it becomes a guide for alignment, the workability of the screw fastening operation between the first leg part 12a and the second leg part 12b and the first reinforcing part 21a is greatly improved.

  In the first embodiment, as shown in FIG. 6, the movable range angle 31b in the attachment direction in the first leg 12 and the second leg 13 is smaller than the movable range angle 31c in the removal direction. Set. The attachment direction is a direction in which the first leg 12 and the second leg 13 are rotated when the blower 2 is attached to the device installation stand 1, and the first vertical portion 121 a of the first leg 12 This is a direction in which the first vertical portion 131a of the second leg 13 approaches each other. That is, the attachment direction is a direction in which the upper ends of the pair of legs 11 approach each other. The removal direction is a direction in which the first leg 12 and the second leg 13 are rotated when the blower 2 is removed from the device installation stand 1, and the first vertical portion 121 a of the first leg 12 The first vertical portion 131a of the second leg 13 is away from each other. That is, the removal direction is a direction in which the upper ends of the pair of legs 11 are separated from each other.

  The movable range angle 31b in the attachment direction is a range of angles in which the first leg 12 and the second leg 13 can be rotated in the attachment direction from the posture along the vertical direction. The movable range angle 31c in the removal direction is a range of angles in which the first leg 12 and the second leg 13 can be rotated in the removal direction from the posture along the vertical direction. The total of the movable range angle 31b in the attachment direction and the movable range angle 31c in the removal direction is a movable range in which each of the first leg 12 and the second leg 13 is rotatable. The angle is 31a.

  In the first embodiment, the rotation restriction unit 212 has a movable range angle 31a of the first leg 12 and the second leg 13 of less than 90 degrees, and the first leg 12 and the second leg. The movable range angle 31b in the 13 attachment direction is limited to be smaller than the movable range angle 31c in the removal direction. Thereby, the first leg body 12 and the second leg body 13 have the amount of collapse in the attachment direction smaller than the amount of collapse in the removal direction, and the distance between the attachment dimensions 31d of the blower 2 is set when the blower 2 is attached. Easy to keep. These rotation ranges can be adjusted to an arbitrary movable range by adjusting the gap dimension 22c shown in FIG.

  And the rotation limiting part 212 which has the structure mentioned above is provided in the both ends of the expansion | extension direction in the 1st reinforcement component 21a and the 2nd reinforcement component 21b.

  Next, an assembly method of the device installation stand 1 and a method of installing the blower 2 will be described. First, the first leg body 12 is formed by screwing the first leg body part 12a and the second leg body part 12b. Moreover, the 2nd leg 13 is formed by screw-fastening the 1st leg part 13a and the 2nd leg part 13b. Next, the attachment plate 14 is screwed to each of the first leg 12 and the second leg 13. The apparatus installation stand 1 is assembled to a temporarily fixed state between the pair of legs 11 and the pair of reinforcing parts 21 before the blower 2 is attached.

  Next, the blower 2 is attached to the apparatus installation stand 1 with the blower 2 sandwiched between the pair of legs 11. When the blower 2 is attached to the device installation stand 1, the second attachment protrusion 2 b provided so as to protrude from one side surface of the blower 2 is attached to the attachment hole of the attachment plate 14 attached to the first leg 12. 15 is inserted. In addition, a second attachment protrusion 2 b that protrudes from the other side surface of the blower 2 is fitted into the attachment hole 15 of the attachment plate 14 attached to the second leg 13.
