Description

[0001]
[Industrial applications]
The present invention relates to a ceiling-suspended air conditioner in which a main body is suspended by a plurality of bolts suspended from a ceiling.
[0002]
[Prior art]
Japanese Utility Model Publication No. 3-3869 and Japanese Utility Model Publication No. 1-25222 are known as one type of such a ceiling-suspended type air conditioner.
In the air conditioner disclosed in the former publication (Japanese Utility Model Publication No. 3-3869), hanging members are arranged on four sides of the main body, and through holes are formed in all of these hanging members. A bolt hanging from the ceiling is passed through each through hole from above, and the hanging bracket is fixed to the bolt with a nut.
[0003]
In the air conditioner disclosed in the latter publication (Japanese Utility Model Publication No. 1-25222), a groove is formed in the hanging metal fitting, and the bolt is engaged from the side of the hanging metal fitting. ing.
[0004]
[Problems to be solved by the invention]
However, in the former air conditioner, since the tip of the bolt must be passed through the hole from above the hanging bracket, there is a problem that the work of passing through the hole is troublesome and quick installation cannot be performed. In particular, if holes are passed through all the hanging fittings, it is difficult to suspend the ceiling where the working posture is not sufficient.
[0005]
In this case, as shown in FIG. 7, a notch 51 opened to the side of the hanging metal member 50 is formed for all the hanging metal members so that the bolt 52 can be engaged with the hanging metal member 50 from the side. Installation is considered possible.
However, in such a configuration, for example, when the main body 53 is abnormally raised at the time of installation, or when the hanging metal fitting 50 is located above the washer 54 attached to the bolt 52 due to an earthquake or the like, the bolt 52 is not attached to the hanging metal fitting 50. It is conceivable that it is easy to come off from it and it is not possible to fix it securely.
[0006]
In the state where the bolt 52 is securely fixed, the distance A between the bolt 52 and the side plate 55 of the main body 53 is large as shown in FIG. Therefore, since a large force is applied to the base piece 56 of the hanging fitting 50 fixed to the side plate 55, it is necessary to securely fix the base piece 56 and the side plate 55. Further, since a large force is applied to the base piece 56, it is necessary to provide the side plate 55 having a strength capable of withstanding this force, and the increase in cost is inevitable with the increase in the thickness of the side plate 55.
[0007]
Therefore, an object of the present invention is to provide an air conditioner that can be easily and reliably installed, and suppresses an increase in a force applied to a main body at the time of installation.
[0008]
[Means for Solving the Problems]
In order to achieve this object, a first aspect of the present invention is to provide a hanging device attached to a side plate of a main body, comprising a horizontal piece and a vertical piece extending from the horizontal piece, and a notch extending from the vertical piece to the horizontal piece. Is provided , and a bolt suspended from the ceiling of the house is inserted into the notch, and furthermore, the horizontal piece of the hanging tool is turned around a fulcrum provided on the horizontal piece, and the elastic force of the spring is used. A stopper is provided on the vertical piece to prevent the bolt from coming off.
[0009]
In the second invention, a hanger is provided on a side plate of a main body in which a heat exchanger and a blower are stored, and the hanger is provided with a notch extending substantially parallel to the side plate, and the notch is hung from a ceiling of a house. The hanging piece is inserted into the horizontal piece , and the hanging piece rotates around a fulcrum provided on the horizontal piece, and is applied to the vertical piece by the elastic force of the spring to prevent the bolt from coming off. it is those you so that with a stopper.
[0010]
[Action]
According to the first invention, when installing the air conditioner, first, the stopper is pushed with a bolt and the bolt is inserted into the through hole. Then, a stopper is applied to the vertical piece to prevent the bolt from coming off the through hole. In addition, the stopper prevents the bolt from moving outside the main body, thereby preventing an increase in the distance between the bolt and the main body.
[0011]
According to the second aspect, when inserting the bolt hanging from the ceiling into the notch of the hanging member of the main body, move the bolt substantially parallel to the side plate while moving the bolt near the side plate of the main body. Let it.
[0012]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the air conditioner 1 is a ceiling-embedded type air conditioner that is suspended and fixed in a ceiling space, and has a suction port 3 in the center of a decorative plate 2 and a pair of outlets on both sides thereof. Openings 4a and 4b are provided for exchanging heat from the air sucked through the inlet 3 and then blowing out the air from the outlets 4a and 4b.
[0013]
In the main body 6, the blower 5 and the heat exchangers 7a and 7b are housed. Further, a pair of blow-out notices 11a and 11b are formed at positions corresponding to the blow-out ports 4a and 4b of the decorative board 2.
A pair of hanging members 13 is provided on one short side plate 12 (see FIG. 2) of the short side of the main body 6, and each is fixed to a bolt 14 hanging from a ceiling. Although not shown, a similar suspending tool is provided on the other side plate on the shorter side, and the main body is suspended by a total of four bolts.
[0014]
The shape of each of these four hanging members 13 is the same as shown in FIG.
In FIG. 3, the hanging member 13 includes a horizontal piece 15, a vertical piece 16 extending downward from the horizontal piece, and a base piece 17 extending downward on the opposite side to the vertical piece. A piece 17 is fixed to the side plate 12 of the main body. Reference numeral 18 denotes a notch extending from the vertical piece 16 to the horizontal piece 15. Reference numeral 19 denotes a stopper, which is attached to the lower surface of the vertical piece 15 via a spring 20. The stopper 19 is positioned by the vertical piece 16. Therefore, the stopper 19 is supported rotatably about the fulcrum 21 as shown by the dashed line arrow.
[0015]
Next, the installation of the air conditioner 1 will be described.
First, the hanging brackets 13 are fixed to the bolts 14 previously suspended from the ceiling of the main body 6. Although the upper end of the bolt 14 is fixed to the ceiling, the lower end is suspended and is a free end.
Specifically, as shown in FIG. 3, first, the bolts 14 are pressed against the stoppers 19 from the sides of the hanging brackets 13, respectively, and inserted into the notches 18.
[0016]
A nut 22 and a washer (washer) 23 are attached to the bolt 14 in advance, and the nut 22 and the washer (washer) 23 are engaged with the hanging member 13 to suspend the main body 6 by the bolt 14.
Here, the stopper 19 is applied to the vertical piece 16 in advance, but when the stopper 19 is pressed by the bolt 14, the stopper 19 rotates toward the main body 6 (side plate 12 side) by the elastic force of the spring 20, and the notch 18 Open. Then, after the bolt 14 has passed through the notch 18, the stopper 19 is rotated toward the opposite side of the main body by the elastic force (restoring force) of the spring 20, and is again applied to the vertical piece 16 (see FIG. 4).
[0017]
Accordingly, the bolt 14 inserted into the notch 18 of the hanging member 13 is locked in the notch 18 by the stopper 19 as shown in FIG. Even when the main body is raised abnormally at times, in the case of an earthquake, etc.), the bolt 14 does not come off from the notch 18, so that the main body 6 does not drop.
[0018]
Here, if the engagement state of the bolt 14 and the hanging tool 13 is shown, it will be as shown in FIG. Since the stopper 19 is provided on the horizontal piece 15, when the bolt 14 is engaged, the washer 23 contacts the stopper 19, and the bolt 14 is located closer to the main body 6 than the vertical piece 16. In other words, since the distance B between the bolt 14 and the side plate 12 of the main body 6 is shortened, the force (moment) applied to the base 17 of the hanging member 13 is reduced.
[0019]
The present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist of the present invention.
For example, in FIG. 3, the spring 20 may be omitted. In this case, when the bolt 14 is inserted into the notch 18, the stopper 19 does not automatically hit the vertical piece 16, so the installation worker needs to manually return the stopper 19 to the vertical piece 16.
[0020]
The vertical piece 16 may be bent above the horizontal piece 15. In this case, the stopper 19 must be provided on the upper surface of the horizontal piece 15.
Further, as shown in FIG. 6, the vertical piece 41 of the hanging tool 40 may be provided not in the side opposite to the side plate 12 but in a direction orthogonal to the side plate 12. Furthermore, the notch 42 into which the bolt 14 is inserted may extend substantially parallel to the side plate 12, and the bolt 14 may be moved substantially parallel to the side plate 12 while moving the bolt 14 close to the side plate 12 (see a solid arrow). ). By doing so, the position of the bolt 14 can be made as close to the main body 6 as possible, and the distance between the bolt 14 and the main body 6 is shortened as described above. As a result, the force (moment) applied to the base piece 43 of the hanging tool 40 is reduced.
[0021]
【The invention's effect】
