  "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.",
  "claims": [
    "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."

  "description_excerpt": "The present invention relates to a unit attaching device for installing a unit in such a manner that the unit is suspended from a ceiling or the like.\n\nWhen a unit or the like is suspended from and fixed to a ceiling, a space above a ceiling, a beam, or the like of a building (hereinafter referred to as ceiling), for example, suspension bolts are attached to the ceiling, and the unit or the like is fixed to the suspension bolts. For example, in the case of an indoor unit installed on the indoor side of an air-conditioning apparatus, suspension brackets of the indoor unit are fixed to suspension bolts, and the indoor unit is suspended from a ceiling. Here, conventionally, the suspension brackets are often provided at positions on the lower side of the unit in the vertical direction (positions closer to the inside of a room (floor) when installed) (see, for example, Patent Literature 1).\n\nPatent Literature 1: Japanese Unexamined Patent Application Publication No. 2013-224771 (FIG. 2)\n\nConventionally, when installing (attaching) an indoor unit to a building, if the distance between the ceiling and the unit is long, the suspension bolts swing largely, and may be broken. Even if braces are added to increase the strength, the suspension bolts swing about lower attachment parts of the braces, and may be broken. In some cases, the suspended unit may fall.\n\nThe present invention is made to solve the above problem, and it is an object of the present invention to provide a unit attaching device that can fix a suspension bolt and a unit to each other and can suppress the swing of the unit and the suspension bolt.",
