BEST MODE FOR CARRYING OUT THE INVENTION Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an example of a mounting base according to the present invention. In these figures, 1 is a ceiling fixing plate, which is usually a hook-shaped material made of metal or the like and is mounted on the ceiling by nuts or bolts embedded in the ceiling. It is fixed. Also, 2 is a hanging metal fitting,
Reference numeral 3 denotes a base, and as shown in the figure, the base 3 has a U-shape, and has a bolt 4 for mounting and fixing the outdoor unit of the air conditioner on a horizontal portion thereof, and the standing portions on both sides are provided in the hanging metal fitting 2. It is slidably fitted, the fixing claw 16 is engaged with the square hole 14 at a required position, and is fixed with a bolt 19 to form an installation mount as a whole, and to the long hole 6 of the ceiling fixing plate 1. It is fastened and fixed by bolts 5.

FIGS. 2A and 2B show details of the mounting and fixing portion between the hanging metal fitting 2 and the ceiling fixing plate 1. For example, FIG.
Recessed portion 8 with respect to the width of the hanging metal fitting as exemplified in (b) and (c)
A bracket 7 having a lower part as a splicing part is used,
The upper side of the hanging metal fitting 2 is fitted into the concave portion 8 of the bracket 7 by abutting the side of the concave portion 8 to prevent the hanging metal fitting 2 from swinging, and penetrates through the bolt hole of the hanging metal fitting and the bolt hole 9 of the bracket. The bolts 5 are fixed to the long holes 6 of the ceiling fixing plate 1 as shown in FIG. Reference numeral 10 denotes a protrusion provided on the bracket 7, and the protrusion 10 is fixed when the ceiling fixing plate 1 is fixed.
Is fixed by the long hole 6 of the ceiling fixing plate 1. Further, as shown in the figure, both side protrusions 11 of the recess 8 are formed in a tapered inclined shape in which the protrusion length is gradually reduced outward. The assembly can be smoothed every time. In the illustrated example, the upper portion of the hanging metal fitting is fitted in the recessed portion 8, but a U-shaped portion is continuously formed in the lower portion of the bracket 7, and a U-shaped surface of the U-shaped portion is formed in a similar shape. It may be attached to the U-shaped inner surface of the hanging fitting made of a U-shaped material so as to prevent lateral vibration.

Further, in order to make it easier to match the outdoor unit mounting pitch on the ceiling fixing plate 1 and the upper portion of the hanging metal fitting 2, as shown in FIG.
On the other hand, the hanging metal fitting 2 is provided with a square hole 13 so that the square hole 13 and the hole indication 12 of the circular shape, the rhombic shape, the triangular shape or the like are aligned with each other. At this time, it is more effective if a triangle mark is attached to the central portion of the ceiling fixing plate 1 and the mounting position is measured and fixed by the square hole 13 of the hanging fitting 2.

FIG. 4 shows a structure for assembling the ceiling fixing plate 1 and the hanging metal fitting 2 as described above before the construction on the site to facilitate the transportation to the site. By loosening the bolt, the hanging metal fitting 2 fixed to the plate 1 is rotated around the bolt portion in the direction of the arrow in the drawing as a fulcrum and can be folded together with the connected base. By doing so, on-site construction can be made easier.

According to the present invention, the base 3 is assembled to the ceiling fixing plate 1 and the suspension fitting 2 configured as described above to form the installation mount, and the suspension fitting 2 and the base 3 at this time are combined. The connection is an important feature of the present invention and is shown in FIG.
~ Fig. 7 shows a specific configuration therefor.

That is, FIGS. 5 (a), (b), (c) and FIG. 6 show an example of the structure of the hanging metal fitting 2 which is advantageous for connection, FIG. 7 shows an example of the structure of the base, and the hanging metal fitting 2 is shown in FIG. , As shown in FIG. 6, it is made of a material having a U-shaped or C-shaped cross section, for example, a metal material such as steel, and the standing portion of the U-shaped or U-shaped base 3 shown in FIG. 7 can slide in the hollow portion. The two are integrally connected by being fitted to. Therefore, the lower part of the hanging metal fitting 2 is cut inward so that the base 3 can be easily inserted, and a plurality of square holes 14 are provided in the lower part of the sliding surface at intervals in the vertical direction. It is also provided on the top and bottom. As shown in FIG. 7, one of the bases 3 faces outward, engages with the square hole 14, and fixes the base 3 to the hanging metal fitting 2 at a required height position.
And inward, projection 17 on the top, stopper 1 on the bottom
8 is projectingly provided, the upright portion of the base 3 is inserted into the suspension fitting 2, and the fixing claw 16 is locked in the square hole 14 of the suspension fitting 2 to temporarily fix the base 3 to the suspension fitting 2. Bolt 19
Fixing of both is achieved by.

In this case, although the fixing claw 16 is a sliding surface in the figure, it may be attached to the side surface as shown in FIG. 7 (c). It is easier to check the parts. Further, it is not always limited to the fixing claws as shown in the drawing, and it is also possible to use a claw 21 with a spring 20 as shown in FIG. 7D.

FIGS. 8 and 9 show the manner of engagement and locking when the hanging fitting 2 and the base 3 are connected. Figure 8
(A), (b), and (c) are modes in which the base 3 is engaged with the lower square hole of the hanging metal fitting 2, and gradually rise as shown in (a), and the upper part of the hanging metal fitting 2 as shown in (b). The fixing claw 16 of the base 3 engages with the square hole, and as shown in (c), the base 3 once descends and is temporarily fixed by locking by claw engagement.
Both are fixed using the bolt 19.

On the other hand, in the case of the lower square hole engagement in FIG. 9, as shown in (a), the base 3 upright portion is sequentially inserted into the suspending metal fitting 2 and raised, and the upper square hole of the upper square hole as shown in (b). In order to engage in the same manner as in the case and to lower the base 3 from this, the base 3 is slightly raised to release the locking of the fixing claw 16 and pulled out downward, and the projection 17 hits the inside of the hanging metal fitting. 15
Stop by touching. These are performed in order to simplify the storage by folding the hanging metal fitting 2 and the base 3 while they are integrated at the time of folding. Thus, the present invention is manufactured as a frame for suspending and installing the outdoor unit of the air conditioner, which simplifies the on-site construction and ensures the assembly.

[0020]

As described above, the present invention has a slidable fitting structure for connecting the hanging metal fittings and the base in the ceiling-mounted installation stand of the air conditioner outdoor unit to the bases so that they can be engaged with each other at desired positions. It has a mating part and has a fitting structure, so it is easy to assemble, and since the engaging part is provided, temporary fixing is performed and connection work is easy, and the installation mount installation work is conventional. In comparison, it is easy and simple. In addition, since the present invention uses the bracket of a predetermined shape to connect the ceiling fixing plate and the hanging metal fitting, the lateral vibration of the hanging metal fitting is prevented, and the hole display to be fitted is provided, so that the outdoor unit mounting pitch can be improved. The advantage of being easy to adapt is that, further, since the hanging metal fitting can be rotated and folded by loosening the fixing bolt of the hanging metal fitting, it is convenient for transportation and the construction time on site can be greatly shortened. Since the bracket has a protruding part that narrows outward, it is easy to insert the hanging metal fitting, and the engaging structure between the hanging metal fitting and the base also hits the fixing claw and the multiple square holes and protrusions, and suspends the stopper. The operation is easy and reliable, and the effect of improving the work efficiency of mounting the mounting base is expected as a whole.
