Since the transport path along which the roller is rolled has a downward slope toward the outside of the window, it can be moved more easily by utilizing this slope.

The groove plate 32e is formed of a member different from the side wall piece 32a in a predetermined shape in order to increase the rigidity of the entire support frame 20, and the side wall piece 32a is formed.
Are fixed in the notches formed by welding and the like, but are not limited thereto.
It is sufficient to form only a cut into which the rail 3 or the like fits in 2a.

Each of the columns 33 is composed of a channel material having a U-shaped cross section, and the channel materials are arranged so that their open portions face each other.
And the engaging portion 32 are connected by the guide pieces 32c, 32c.
The upper end of the support column 33 is inserted into a region formed by the back surface of the base plate, the tips of the inward protruding pieces 32b and 32b, and the inner sidewalls on the front end side of the side wall pieces 32a and 32a. This is done by fixing and by welding.

Each pillar 33 has a pair of side surfaces 33a of the channel material facing each other, and the inner surfaces of the bush 30
Is a sliding surface S on which sliding contact is made.

As shown in FIGS. 2 and 5, the bush 30 is provided with a shaft 3 supported by support brackets 28, 28.
The bush 30 and the sliding surface S are attached to both ends of the outdoor unit 8 and move along the sliding surface S.
Is extremely important for lowering at an optimal lowering speed.

In order to attach the outdoor unit 8 to the support column 33 safely and easily, the bush 30 and the support column 33 support the weight of the outdoor unit 8 and provide a predetermined frictional resistance so that the outdoor unit 8 can be lowered at an optimum lowering speed. It is desirable to have one.

In order to exhibit such frictional resistance, the hardness or compression rate of the bush 30 which is an elastic body corresponding to a desired descending speed may be set. When this compression rate is obtained by an experiment, it is preferable to set the compression rate of the bush 30 to about 15% when a general rubber bush is used for the bush 30 which is the elastic body. It has been found.

Therefore, in the present embodiment, the outer diameter D of the bush 30 shown in FIG. 6 is set so that this compression rate can be obtained.
And the distance L between both sliding surfaces S are set so that the bush 30 descends in a state of being compressed by a predetermined amount.

However, in addition to this, the hardness of the rubber may be adjusted, or the material of the sliding surface S may be appropriately selected to obtain a desired friction resistance.

In the present embodiment, the bush 30 is attached to the support column 3.
The guide piece 32c for lowering it toward the
The guide piece 32c is provided on each of the columns 33
It may be provided on the top of the.

Even in this manner, when the bush 30 is placed on the engaging portion 32 with the back surface of the outdoor unit 8 facing downward and the outdoor unit 8 is moved to the foremost end of the engaging portion 32, the bush 30 Collide with the guide piece 32c, and push the bush 30 to the support column 33.

FIG. 7 is an enlarged perspective view showing the mounting state of the bolt shown in FIG. 1, FIG. 8 is a perspective view showing a modified example of the mounting state of the bolt, and FIGS. 9A and 9B are sectional views showing spacers. is there.

As shown in FIG. 7, the bolt 39 is attached to the opposite side pieces 33a by penetrating the opposite side pieces 33a, so that the strength of the support column 33 is improved against twisting and the like.

Further, since the mounting position of the bolt 39 can be adjusted by selecting the through hole O, the outdoor unit 8 can be set at a desired position, and as a result, the indoor unit R (see FIG. 8).
The length of the pipe P for connecting the outdoor unit 8 and the outdoor unit 8 can be set to be constant, and the cost of the outdoor unit mounting apparatus can be significantly reduced by sharing the components.

That is, since the size of the window of each household is not uniform and variously different, the length of the piping pipe P extending through this window is originally set individually. Preferably. But if you do this,
Even the pipe P for piping is not an outdoor unit mounting unit as one set, and the cost is high.

Therefore, in the present embodiment, the length of the pipe P for piping is made uniform, and the length adjustment at the time of pipe mounting caused by this is performed by the mounting position of the outdoor unit.

If the mounting position of the outdoor unit can be adjusted in this way, the position of the outdoor unit can be set in consideration of the height of the window, and the outdoor unit can be installed so that the view from the window is not obstructed by the outdoor unit. There are also secondary advantages such as installation.

However, when the bush 30 is placed on the bolt 39 that functions as this stopper, the bush 30
Takes the weight of the outdoor unit 8, especially the rubber bush 30.
In the case of, it may be deteriorated during long-term use, and its elasticity may be reduced.

Therefore, in this embodiment, as shown in FIG. 8, an arcuate shape having an upper surface for supporting the rubber bush 30 having a cylindrical shape is provided inside the support column of the bolt 39 functioning as a stopper. Spacer Sp with recess r
Is provided and is fixed by a bolt 39 so that the bush 30 is placed in the recess r of the spacer Sp.

The recess r of the spacer Sp is not limited to the arc shape, but may be any shape as long as it conforms to the shape of the bush 30. The spacer Sp also has a shape shown in FIG. 9A, not only a deformed plate member, but also an elastic member such as rubber fitted inside the plate member as shown in FIG. 9A, or a plate member of relatively hard hardness as shown in FIG. 9B. It may be made of a certain synthetic resin or the like.

Further, as shown in FIG. 1, a support member 41 is provided at the lower end of each column 33, one end of which abuts the outer wall 5 via the elastic piece 40 and the other end of which projects into the column 33. ing.

The support member 41 is for mounting the support frame 20 in parallel with the outer wall 5 and for preventing the vibration of the outdoor unit 8 from being transmitted to the room through the outer wall 5.
Preferably, the distal end portion 41a of the support member 41 is configured to protrude into the support post 33, and when the stopper function of the bolt 39 does not function for any reason, the outdoor unit 8 cannot be supported. The tip 4 of the support member 41
1a may contact the bush 30.

In this way, since the support member 41 also serves as a kind of stopper, it becomes a so-called double stopper in combination with the stopper function of the bolt 39, so that the outdoor unit 8 can be supported more safely.

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

In FIG. 10, the support frame 20 is covered with the cover plate 4
3 is a schematic perspective view showing a state of being engaged with the window sash 2 by FIG. 3, and FIG. 11 is a sectional view taken along line 11-11 of FIG.

In order to prevent the support frame body 20 from rising and to ensure that the support frame body 20 is engaged with the rail 3 of the window sash 2, a screw is screwed onto each engagement portion 32 from above. However, the engaging portion 32 may be directly fixed to the window sash 2.
It may be configured as shown in FIGS.

The floating preventing means U is composed of the support frame 2
After the cover 0 is attached to the window sash 2, the engaging portions 32, 32 of the support frame 20 are covered with a cover plate 43 having an L-shaped cross section, and the cover plate 43 and the window sash 2 are fixed with screws 44. It is like that. in this case,
The width m1 of the cover plate 43 is equal to or less than the width m2 of the piping panel 45 attached to the window sash 2, and when the window is closed, the window is not hindered by the cover plate 43 and the window It is preferable to be configured so as to surely contact the end of the.

However, it is preferable that the screw 44 is fitted into the long hole 46 formed in the cover plate 43. In this manner, no matter what width the window sash 2 has, the bent end portion 43a of the cover plate 43 can be attached to the window sash 2 in a state where it is in contact with the window sash 2, thereby providing a cover without any problem. The plate 43 can prevent the support frame 20 from rising.

A protrusion 43b is provided on the upper surface of the cover plate 43, and the pipe panel 4 is attached to the protrusion 43b.
5 at the lower end to prevent air leakage
The support of 5 may be made more reliable. Further, as shown by a broken line in FIG. 11, the bent end portion 43a of the cover plate 43 may be further bent so that the tip easily contacts the inner surface of the wall 5.

In FIGS. 1 and 10, the reference numeral "50" is a reinforcing angle member, and the reference numeral "W" is a window in FIG.

Next, the operation will be described. Outdoor unit 8 outside the window
First, the supporting frame 20
Only to the window W. Engagement part 32 of support frame 20
Has the groove plate 32e, so that the groove 32d of the groove plate 32e is engaged with the rail 3 or the 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 protruding length of the support member 41 is adjusted so that the support frame 20 is parallel to the wall 5.
Further, in order to prevent the support frame 20 from falling down, tilting or lifting up in the horizontal direction, a screw or the like is screwed in from the upper surface or side surface of each engaging portion 32, particularly the groove plate 32e, and fixed to the window sash 2. Is also good.

Then, the bolt 39 is screwed into the column 33 at a predetermined position in the vertical direction, and the tip of the bolt 39 is attached so as to project into the column 33. The screw 39 is screwed in at a position corresponding to the length of the pipe P.

When the mounting of the support frame 20 is completed in this way, the outdoor unit 8 is lifted, and as shown in FIG.
The bush 30 is placed on the upper surface of the inward protruding piece 32b such that the back surface of the outdoor unit 8 faces downward. Then, when the outdoor unit 8 is moved by using the side wall pieces 32a, 32a as lateral guides and the upper surface of the inward protruding piece 32b as a transport path, and the bush 30 is pushed out from the room to the outside, the bush 30 becomes
At the end position of the inward protruding piece 32b, it collides with the guide piece 32c of the engaging portion 32.

Since the diameter D of the bush 30 is set to be larger than the width L between the sliding surfaces S of the support column 33, the bush 30 does not immediately enter the support column 33, but temporarily stops there. That is, the outdoor unit 8 can move the outdoor unit 8 toward the outside of the window without performing the operation of confirming the forward end.

Therefore, the outdoor unit 8 can change its posture smoothly from the horizontal state to the vertical state with the bush 30 as a fulcrum.

In the present embodiment, even if the outdoor unit 8 is not necessarily placed in a completely vertical state, the bush 30 comes into the support column 33 when the outdoor unit 8 is raised from a certain horizontal state. This means that it is possible to drop the outdoor unit 8 into the support column 33 without unnecessarily raising the outdoor unit 8 toward the outside of the window, so it is relatively safe when mounting at a high place. Can work.

When the outdoor unit 8 is in the vertical state, its own weight overcomes the frictional resistance between the bush 30 and the support column 33, and moves downward along the sliding surface S itself. 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 smoothly and gently along the column 33.

When the outdoor unit 8 descends to a predetermined position along the column 33, the outdoor unit 8 comes into contact with a bolt 39 serving as a stopper, and the bush 30 is placed on the bolt 39.
The movement of the outdoor unit 8 stops.

After this stop, when the guide piece 32c and the bracket 23 are attached by the bolts 37 and the nuts 38 via the vibration-proof elastic members 36, the outdoor unit 8 is in a state of being elastically supported by the columns 33. Fixed at.

When the pipe P is connected to the indoor unit R after the outdoor unit 8 is fixed, the refrigerant previously sealed in the outdoor unit 8 fills the entire cooling device.

Therefore, when the outdoor unit 8 is operated, the normal cooling or heating operation is performed. The vibration and noise of the outdoor unit 8 are caused not only by the elastic member 36 and the elastic packing but also by the bush 30. The vibration is not transmitted to the support column 33, so that the vibration transmission to the indoor side is surely prevented.

Even if the bolt 39 is not set so as to protrude into the column 33, since the distal end portion of the support member 41 protrudes into the column 33, the bolt 39 must be set at the lower end of the column. Since the L-shaped angle members 42 are provided, these serve as a kind of stopper, and the outdoor unit 8
Is no problem.

Even when the outdoor unit 8 is moved from the indoor to the outdoor as described above, the operator simply moves the inward protruding piece 32.
It is only necessary to slide the upper surface of b, and even when the outdoor unit 8 is placed outdoors, the outdoor unit 8 can be held immediately by the frictional resistance between the bush 30 and the support column 33, so that the body is burdened. Moreover, the outdoor unit 8 can be easily set in a predetermined place, and the work becomes extremely easy.

Even when the installation place is on the second floor or above, there is no need to hang a ladder or lift the outdoor unit 8 using the ladder, and to carry out the body from the inside of the room and carry it out of the window. , Work safety is also secured.

The present invention is not limited to the above-described embodiments, 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. By doing so, the range of adjustment of the mounting position of the outdoor unit 8 is further increased, and the versatility is increased.

Further, as shown in FIGS. 13 and 15A, it is also possible to use a column 33A having a T-shaped cross section. Note that FIG. 15A is a cross-sectional view taken along the line AA of FIG. 13, and FIGS. 15B to 15D are views corresponding to FIG. 14A showing another modification.

In the case of the support column 33A, as shown in FIG. 15A, a bush 30 in which a groove 30a is formed so as to sandwich the inward protruding rail 51 from both sides is used. The control of the descending speed is determined by the width of the groove 30a and the thickness of the inward protruding rail 51.

The through hole O for inserting the bolt 39 is to be opened in the inward protruding rail 51, and the bolt 39 attached here is preferably a headless one such as a hexagon socket head cap screw. Preference is given to using. When the outdoor unit 8 is lowered from above along the column 33A, the bush 3
This is to ensure that 0 is placed on the bolt 39.

The pillar 3 having such a T-shaped cross section
When 3A is used, unlike the above-mentioned support 33, the support 3
There is no fear that the outdoor unit 8 cannot be attached due to an incorrect attachment state of the outdoor unit 3, and the columns 33A can be reliably installed so as to face each other from the appearance.

As described above, according to the present invention, the following effects can be obtained for each claim. According to the invention of claim 1, when the outdoor unit is attached to the support column of the support frame while controlling the descending speed by the frictional resistance between the bush and the support column, the worker can work extremely easily and safely without burden. Can be completed, and the installation work becomes inexpensive. Also, if the stopper is set at a predetermined position in advance, the outdoor unit can be set at a desired position, and the length of the pipe connecting the indoor unit and the outdoor unit can be set to be constant, resulting in a large cost of the device. Further, since the bush having elasticity can be used, the bush can act as a kind of cushioning material between the stopper and the stopper after the attachment, and has a vibration damping function. Further, if the stopper is set in consideration of the height of the window, the view from the window will not be obstructed by the outdoor unit.

According to the invention as set forth in claim 2, since the guide portion is formed on the top of the supporting column, if the outdoor unit is placed on the engaging portion and moved forward so as to slide on the engaging portion, The bush comes into contact with the guide member and guides the bush between the sliding surfaces of the support columns, which makes it easier to mount the outdoor unit.

According to the third aspect of the present invention, the support member is provided at the lower end of the column, one end of the support member elastically abuts the outer wall, and the other end projects into the channel member. The outdoor unit is supported reliably, and in combination with the elastic bush, vibration from the outdoor unit is not transmitted to the wall, quiet operation is possible, and the tip of this support member functions as a kind of stopper. When combined with the above-mentioned stopper, it becomes a double stopper and supports the outdoor unit more safely.
