Abstract

The unit attaching device of the present invention has suspension brackets that have a hole for passing a suspension bolt suspended from a ceiling and that are installed to an indoor unit that is a unit to be suspended. The suspension brackets are installed on the ceiling side of the side surface of a housing of the indoor unit. For example, when an earthquake or the like occurs, the distance between a part that is the base point of the swing of the suspension bolt and the installation position of the unit can be reduced.

First claim

The invention claimed is:

1. A unit attaching device comprising
a first suspension bracket having a first hole adapted to pass a suspension bolt suspended from a ceiling and installed to a unit to be suspended, and
a second suspension bracket having a second hole adapted to pass the suspension bolt,
wherein the first suspension bracket has a first flat portion having the first hole,
wherein the second suspension bracket has
a second flat portion having the second hole,
a hooking portion having a flat surface, and
a connecting portion that connects the second flat portion and the hooking portion,

wherein the first suspension bracket is installed on one of a ceiling side and a floor side of a side surface of a housing of the unit and the second suspension bracket is installed on an other of the ceiling side and the floor side of the side surface of the housing of the unit, and
the flat surface of the hooking portion of the second suspension bracket is superposed onto the first flat portion of the first suspension bracket such that the first suspension bracket and the second suspension bracket are engaged.

2. The unit attaching device of claim 1 , wherein at least two of the first and second suspension brackets installed at a plurality of locations on the unit are same suspension brackets.

3. The unit attaching device of claim 1 , wherein the first and second suspension brackets have a screwing elongate hole for screwing to the housing of the unit.

4. An indoor unit being the unit to be suspended and to which the unit attaching device of claim 1 is installed.

5. The unit attaching device of claim 1 , wherein
each of the first hole and the second hole is elongate in a first direction perpendicular to the suspension bolt, and
each of the first and second suspension brackets has a slit that communicates with the elongate hole in a second direction perpendicular to the suspension bolt, the second direction is eccentric to the first direction.

6. The unit attaching device of claim 1 , wherein
the second flat portion of the second suspension bracket installed on the ceiling side of the unit and a top plate of the unit are at substantially the same position in the height direction.

7. A unit with unit attaching device, comprising:
a unit to be suspended, and
the unit attaching device of claim 1 installed on the unit.

8. The unit attaching device of claim 1 , wherein
the flat surface of the hooking portion of the second suspension bracket has a third hole adapted to pass the suspension bolt, and
the third hole of the second suspension bracket is formed so that the third hole overlaps with the first hole of the first suspension bracket in a state in which the first suspension bracket and the second suspension bracket are engaged.
