Description

[Detailed Description of the Invention] Fig. 1 shows a method of installing a conventional ceiling-embedded air conditioner.

2 is a detailed view of part A in FIG. 1, and FIG. 3 is a perspective view of the hanging fitting.

The hanging bolt 1 with the attic nut 5 is hung down, the washer 4 is engaged with the hanging bolt 1, and the washer 4 is engaged with the hole 3a of the hanging fitting 3 provided in the main body 2.
a, Oak) Attach 5a to hanging bolt 1.

Next, align the flange portion 2a of the main body 2 with the lower surface of the ceiling 6 while adjusting the flange portion 2a (5, 5a) up and down.

Thereafter, by means not shown, the decorative panel 7 is attached to the main body 2.
hold it.

In this installation method, in order to engage the hanging bolt 1 with the hole 3a of the hanging bracket 3, several workers support the main body 2 (usually weighing about 50 kg) from below while installing it in the ceiling. It is necessary to position the main body 2 according to instructions from the operator, and the adjustment can only be made by the margin of the diameter of the hole 3a of the hanging fitting 3 relative to the diameter of the hanging bolt 1, making the work laborious and dangerous.

The present invention has been devised in view of the above, and embodiments thereof will be specifically described below with reference to FIG. 4 and subsequent figures.

FIG. 4 is a main body installation procedure diagram showing the first embodiment of the present invention;
Fig. 5 is a perspective view of a rail used in this, and Fig. 6 is a perspective view of a hanging fitting used in this. A pair of rails, 11 is a hanging metal fitting having a notch 11a, and 12, 12a are nuts screwed into the hanging bolt 1.

The approximate height of the rail 10 is determined by engaging the hole 10a of the rail 10 with the hanging bolt 1 with a nut 12 hanging from the attic and screwing in the lug H2a.

Lift the main body 2 to which the hanging fitting 11 has been fixed in advance upward from the opening in the ceiling 6 and place it on the surface 10C of the rail 10 and the hanging fitting 11.
In order to engage the surface 11b, the main body 2 is tilted slightly so that the hanging fitting 11 passes between the rails 10, or the space between the rails 10 is widened in advance, and the main body 2 is passed between the rails 10 as shown in FIG. 2 on the rail 10, slide the hanging fitting 11 of the main body 2 on the rail so that the flange 2a of the main body 2 applies a load evenly on the left and right sides of the ceiling hole, and position the notch 11a. These are fastened with bolts and nuts using the elongated holes 10b.

Thereafter, the height of the main body 2 is finally determined by moving the nuts 12, 128 up and down.

Thereafter, the decorative panel 7 is held on the main body 2 by means not shown, and the installation is completed.

This eliminates the need for the operator to support the main body from below when adjusting the position of the main body relative to the ceiling opening.

In addition, installation is simplified because only the sliding work is required after the main body is mounted, and there is no need to align the holes of the hanging bolts and hanging fittings as in the conventional case.

7 and 8 show a second embodiment of the present invention,
The procedure is the same as in the first embodiment until the rail 10 is held by the hanging bolt 1.

However, the rail 10 and the hanging bolt 1 are fixed at this stage.

The hanging bolt 13 is positioned and fixed in the elongated hole 10b of the rail 10 with respect to the notch 11a of the hanging fitting 11 fixed to the main body 2 and the ceiling hole 6a.

As shown in Figure 8, the hanging ports 1 to 13 have nuts 14.
, 14a, washers 15, 15a are fitted in advance, and while lifting the main body 2, the hanging bolt 13 is expanded relative to the hanging fitting 11, and the hanging bolt 13 is fitted into the notch 11a of the hanging fitting 11.

Next, nut 14.14 a for hanging bolt 13
The height of the main body 2 is determined by adjusting the amount of screwing in.

After this, the decorative panel 7 is held on the main body 2, and the installation is completed.

In this case, vertical position adjustment can be performed from below the ceiling.

Note that the work of fixing the hanging bolts 13 to the rails 10 can be carried out by entering the ceiling space through the ceiling opening for installing the main body, so there is no need for a special ceiling entrance.

Therefore, there is no need to provide a new entrance/exit in the ceiling.

9 and 10 show a third embodiment of the present invention, in which a pair of left and right rails 9 as shown in FIG. 10 are provided intersectingly on the rail 10 shown in FIG. 7. There is.

Engage the hole 9a of the rail 9 with the hanging bolt 1 and then remove it) 12
Screw in a to determine the approximate height of the rail 9.

Next, alignment with the ceiling opening in the longitudinal direction is performed by engaging the long holes 9b of the rail 9 and the holes 10a of the rail 10a, and fastening them using bolts and nuts.

After this, the process is the same as described above, and in addition to the improvements mentioned above, the alignment between the hanging bolt position and the ceiling opening can be moved back and forth and left and right, improving work efficiency.
