FIG. 4 is an explanatory view showing a state when the bush slides, and FIG. 5 is an explanatory view showing an attached state of the outdoor unit. In the figure, the same reference numerals are used for members common to those shown in FIG.

Referring to FIG. 1, the outdoor unit mounting apparatus according to the present embodiment mounts and supports an outdoor unit 8 on a support frame 20.

First, the outdoor unit 8 will be described. The outdoor unit 8 has a box-shaped case 21 in which cooling components such as a compressor, an outdoor heat exchanger, a fan, and a motor are housed. ing. The box-shaped case 21 has a flat rear surface with a pipe (not shown) for a refrigerant pipe, a handle 22 at the top for facilitating transportation or handling, and a plurality of sides for connecting to the support frame 20 at the side. Are provided respectively. The mounting brackets 23 are elastic packings (not shown) for improving vibration isolation.
Is connected to the support frame 20 by screws or bolts.

In the outdoor unit 8, by operating the internal fan, outside air is introduced into the inside from the air inlets 24 and 25, and the outdoor heat exchanger 26 and the like are cooled.
The air is discharged from the air discharge port 27 to the outside.

In particular, in the outdoor unit 8 of the present embodiment, support brackets 28, 28 protruding toward the support frame 20 are attached to both lower sides of the box-shaped case 21. A shaft 31 is provided therein, and a bush 30 made of an elastic material such as a cylindrical rubber is attached to both ends of the shaft 31.

Here, the bush 30 will be described in detail later. When the bush 30 moves downward along the column together with the outdoor unit 8, the lower part of the outdoor unit 8 is generated due to frictional resistance between the bush 30 and the sliding surface S. A member for controlling the moving speed, which is fitted between a pair of sliding surfaces S formed on the column 33 and exerts a predetermined frictional resistance with the sliding surface S. Is not limited to a cylindrical one or a polygonal one.

On the other hand, the support frame 20 is provided with a window sash 2 (FIG. 2).
Horizontal surface 32 having a groove 32a for engaging with the rail 3 or the drainer when placed on the upper surface and having a flat upper surface.
b, a pair of engaging portions 32, 32,
2 has columns 33, 33 suspended along the outer wall 5 on which the window sash 2 is mounted.

Each of the engaging portions 32 is formed of a U-shaped channel material as a whole, and one side piece 32c on the base end side attached to the column 33 projects and is fixed to the column 33 by welding or the like. ing.

In forming the groove 32a, not only a part of the engaging portion 32 is cut off, but another member is fitted into the groove 32a in order to more securely engage with the rail 3 or the like. May be.

The column 33 is also formed of a pair of U-shaped channel members similar to the engaging portion 32. The channel member slides on the inner surfaces of a pair of opposing pieces 33a with which the bush 30 slides. The strut 33 is set so that the open portions of the channel material face each other.

As shown in detail in FIGS. 3 and 4, the bush 30 is attached to both ends of a shaft 31. The shaft 31 is supported by support brackets 28, 28 provided in the immediate vicinity of a column 33. However, the relationship between the bush 30 and the sliding surface S of the piece 33a is important.

That is, since the bush 30 is controlled so as to obtain an optimum descending speed with respect to the weight of the outdoor unit 8, the elastic hardness or the compressibility is set in accordance with the descending speed. Is preferred. For example, when a general rubber bush is used as in the present embodiment, the distance between the outer diameter D of the bush 30 and the two sliding surfaces S is adjusted so that the compression ratio of the bush is about 15%. It is preferable to set L and lower the bush 30 in a compressed state as shown in FIG.

However, the present invention is not limited to this, and the hardness of the rubber may be adjusted or the material of the sliding surface S may be appropriately selected so that a desired frictional resistance can be obtained.

As shown in FIGS. 1 and 2, a guide member 34 is provided at the top of each support 33. The guide member 34 places the bush 30 on the horizontal surface 32b of the engaging portion 32 with the back surface of the outdoor unit 8 facing down.
When the outdoor unit 8 is moved upward and the outer unit 8 is located at the forefront end of the engaging portion 32, it collides with the bush 30 and guides the bush 30 into the support 33.

A substantially U-shaped notch 35 is formed in the guide member 34, and an elastic member 36 for vibration isolation is provided here.
Is mounted, and the mounting bracket 23 of the outdoor unit 8 is elastically supported by the bolts 37 and the nuts 38.

Each of the columns 33 has three pieces on each side piece 33b.
A through-hole O is opened, and a bolt 39 is attached through both of the through-holes O. The bolt 39 is attached to the bush 30 when the bush 30 is lowered together with the outdoor unit 8 in the column 33. Function as a stopper to stop the outdoor unit 8 at a predetermined position. In particular, since the bolt 39 is attached through the opposing side pieces 33b, the strength of the column 33 is improved against torsion and the like. If a weld nut or the like is attached to one of the side pieces 33b, the assembling property is further improved.

A support member 41 is provided at the lower end of each support 33, one end of which abuts the outer wall 5 via an elastic piece 40, and the other end of which projects into the support 33.

The support member 41 is for mounting the support frame 20 so as to be parallel to the outer wall 5.
This is to prevent the vibration of the outdoor unit 8 from being transmitted to the room through the outer wall 5, but preferably, the distal end portion 41 a of the support member 41 is configured to project into the column 33, and the bolt When the stopper function 39 does not function for some reason and the outdoor unit 8 cannot be supported, the tip 41a of the support member 41 is connected to the bush 30.
The support member 41 serves as a kind of stopper. In this way, in combination with the stopper function of the bolt 39, it becomes a so-called double stopper, so that the outdoor unit 8 can be supported more safely.

In the present embodiment, an L-shaped angle member 42 is attached to the lower end of the column 33 to further improve safety.
Are fixed by welding or the like, and the lower end opening of the column 33 is closed by the angle member 42.

Further, the support frame 20 is prevented from being lifted,
To ensure that the support frame 20 is engaged with the rail 3 of the window sash 2, screws are screwed into the respective engagement portions 32 from above, and the engagement portions 32 are directly fixed to the window sash 2. Alternatively, a means such as covering the engagement portions 32 with a cover plate (not shown) and fixing the cover plate and the window sash 2 with screws may be employed. However, it is preferable that the head of the screw does not protrude from the upper surface of the engagement portion 33.

In FIG. 1, reference numeral "43" denotes a reinforcing angle material.

Next, the operation will be described. In order to install the outdoor unit 8 by the window hanging method, first, only the support frame 20 is attached to the window bar. The engaging portion 32 of the support frame 20 is
Since the groove 32a is provided, the groove 32a is engaged with the rail 3 or drainer of the window sash 2, and the entire support frame 20 is hung down along the outer wall 5 of the window.

In this case, the projecting length of the support member 41 is adjusted so that the support frame 20 is parallel to the wall. Further, in order to prevent the support frame 20 from falling down, tilting or lifting up in the horizontal direction, each engaging portion 32 may be fixed to the window sash 2 with screws or the like.

Then, a bolt 39 is attached to a predetermined position in the vertical direction of the column 33, and the vertical mounting position of the outdoor unit 8 is determined in advance.

When the mounting of the support frame 20 is completed in this way, the outdoor unit 8 is lifted, and the rear surface of the outdoor unit 8 is placed on the upper surface 32b of the horizontal engaging portion 32 as shown in FIG. Put it on. Then, the outdoor unit 8 is moved horizontally on the upper surface 32b of the engaging portion 32, and the bush 30 is pushed forward.

The bush 30 collides with a side surface of a guide member 34 provided on the top of the column 33, and the bush 30 is guided between the sliding surfaces S of the column 33. The installation work of the outdoor unit 8 can be performed without performing a troublesome checking operation such as checking.

Since the diameter D of the bush 30 is larger than the width L of the sliding surface S of the column 33, the bush 30 does not easily fall into the column 33 even by the collision. The posture of the outdoor unit 8 can be changed so as to smoothly change from the horizontal state to the vertical state with the bush 30 as a fulcrum. And when it becomes a vertical state, the outdoor unit 8
The overall weight overcomes the frictional resistance between the bush 30 and the column 33, and the outdoor unit 8 moves downward along the sliding surface S. However, since the speed of this downward movement is controlled by the frictional resistance between the bush 30 and the column 33, the outdoor unit 8 descends along the column 33 smoothly and gently.

The outdoor unit 8 includes a bolt 3 serving as a stopper.
9, when the bush 30 is placed on the bolt 39, the movement of the outdoor unit 8 stops.

After this stop, the guide member 34 and the bracket 23 are attached by a bolt 37 and a nut 38 via an anti-vibration material 36, and the other bracket 23 and the support 33 are connected by screws or the like via an elastic packing. If connected, the outdoor unit 8 can be fixed in a state where it is elastically supported by the column 33.

Therefore, even if this outdoor unit 8 is operated,
Vibration and noise are not transmitted to the column 33 not only by the elastic member 36 and the elastic packing but also by the bush 30, whereby the transmission of vibration to the indoor side is reliably prevented.

Even if the bolt 39 is not set on the column 33, since the tip of the support member 41 protrudes into the column 33, an L-shaped angle member 42 is attached to the lower end of the column. Are provided, these serve as a kind of stopper, and there is no problem in supporting the outdoor unit 8.

As described above, when the outdoor unit 8 is moved from indoor to outdoor, the operator only has to slide on the engaging portion 32 or the like. Immediately due to the frictional resistance between the bush 30 and the column 33, the outdoor unit 8
Can be held, so that the outdoor unit 8 can be set at a predetermined place without putting a burden on the body,
The work becomes extremely easy.

Even when the installation location is on the second floor or higher, there is no need to hang a ladder or use the ladder to lift the outdoor unit 8, and it is not necessary to get out of the window by leaning out from the indoor side. Also, work safety is ensured.

Furthermore, if the position of the bolt 39 is appropriately selected in consideration of the height of the window and the size of the outdoor unit 8, the outdoor unit 8
The view from the window is not obstructed.

The present invention is not limited to the above-described embodiment, but can be variously modified and used within the scope of the claims. For example, in the above-described embodiment,
The length of the support frame 20 is fixed, but the present invention is not limited to this, and the support frame 20 may be extended.

In the above embodiment, the upper surface 3 of the engaging portion 32
2b is horizontal, but not only this,
The upper surface 32b of the second 2 may be slightly downwardly inclined. In this way, the movement of the outdoor unit 8 on the upper surface of the engagement portion is relatively easy. Upper surface 32 of this engaging portion 32
If a member that guides the bush 30 is provided on the side of “b”, the outdoor unit 8 can be moved on the upper surface 32 b of the engagement portion 32 with more security.

FIG. 6 is a perspective view of a bush portion according to another embodiment of the present invention, and FIG. 7 is an explanatory view showing an attached state of the embodiment.

When the outdoor unit 8 is to be lowered more gently than in the above-described embodiment, the bush 30 is improved so as to be connected to the shaft 31 outside the bush 30 as shown in FIG. It is good also as what has the flange part 50 provided. The size of the support post 33 is also set so that the bush 30 and the flange portion 50 can be inserted therein, and a coil spring 51 is provided between the bush 30 and the flange portion 50 as shown in FIG. .

In this manner, the outdoor unit 8 is connected to the engaging portion 32.
When it is moved upward, a coil spring 51 is engaged between the bush 30 and the flange portion 50, and the outdoor unit 8
Is lowered along the column, the lowering speed of the outdoor unit 8 is further reduced by the elastic force of the coil spring 51.
