Description

[Detailed Description of the Invention] This invention relates to a support device for supporting a ceiling-suspended air conditioner on the ceiling with bolts and nuts.

Conventionally, as a means of mounting this type of air conditioner on the ceiling,
There is a system in which a support bracket is attached to the ceiling in advance, the air conditioner is lifted close to the ceiling, and a bolt is threaded between the air conditioner and the support bracket to support the air conditioner. With the support means, it is necessary to lift the heavy air conditioner for a long time while aligning the air conditioner with the support fittings and bolting them, which is very dangerous and requires a large number of workers. There are drawbacks.

Therefore, recently, as shown in Fig. 4, a U-shaped support bracket is installed on the ceiling a, and a U-shaped hanging bracket d is attached to the air conditioner C, so that the open parts of the hanging brackets S and D face each other. When installing the air conditioner C to support the air conditioner C, slide the hanging fitting d of the air conditioner C into the support fitting from the front and lock it, and the air conditioner With C suspended, bolt e is inserted between the hanging fittings and d.
I am trying to fix it with.

By the way, with this kind of support means, the air conditioner C is suspended by the hanging fittings d and the supporting fittings and bolted, so there is less danger than in the case described above, and fewer workers are required. Although there are advantages, since two metal fittings are used, the gap between the air conditioner C and the ceiling a increases, and the number of parts required to install the air conditioner C increases, resulting in an increase in cost.

This invention was devised to eliminate the above problems, and it eliminates the need to lift the heavy object of the air conditioner at a high place for a long time, and makes it easier to hang the air conditioner from the ceiling. The purpose of this product is to improve workability and allow it to be mounted closely to the ceiling, and its features are as follows.

That is, the mounting plate attached to the top plate side of the casing of the air conditioner is formed from a horizontal piece that is substantially flush with the top plate and a bent piece whose rear end is bent downward, and On the front side of the horizontal piece, an insertion hole through which a nut to be screwed onto the mounting bolt can be inserted is provided, and an elongated hole with a width slightly larger than the diameter of the mounting bolt is provided continuously in front of the insertion hole. A communicating hole is continuously provided in the horizontal piece and an insertion hole is provided in the bent piece at the corner with the side bent piece so that the nut can be inserted from an oblique direction of the casing, and a continuous hole is provided in front of the communicating hole. and provide an elongated hole with a width slightly larger than the diameter of the bolt, and insert the nut into the communication hole and the insertion hole in the corner part, and the length from the corner of the horizontal piece to the center of the front insertion hole. It is characterized by being longer than the length between the centers of two mounting bolts located in the front and back direction so that when the bolt moves slightly and is supported in the rear elongated hole, the front nut can be inserted into the front insertion hole. shall be.

To hang the air conditioner from the ceiling by cutting it, first lift the entire unit and tilt it forward, connect the nuts to the communication holes and insertion holes in the rear corner of the casing, and then move the casing slightly backwards to attach the air conditioner to the ceiling. The rear part of the air conditioner is temporarily supported in the rear elongated hole, and then the whole body is suspended by inserting the front bolt into the front insertion hole and moving rearward.By screwing the nut, the air conditioner is suspended. Since it is fixed in a predetermined position, the work of attaching it tightly to the ceiling has become much easier.

Next, the details of the present invention will be explained with reference to the embodiments shown in the drawings.

Furthermore, each of the through holes 9, 9, the communication hole 10b and the insertion hole 10a are elongated holes 11, 11 with a width slightly larger than the diameter of the bolt 1, which is approximately the same size as the through hole 9, respectively.
This makes it continuous.

The length L between the corner edge of the horizontal piece 8a on the bent piece 8b side and the center of the insertion hole 10a is set to be larger than the longitudinal direction l between the bolts 1 and 1 as described above. be.

Furthermore, the new piece 8b is provided with an insertion hole 12 that is continuous with the communication hole 10b, and is formed to have a large diameter so that the nut 4 can be inserted into the casing 5 from the diagonal rear direction.

This bent piece 8b also serves to double-string the circumferential surface of the large-diameter communication hole 10b located at the rear end of the horizontal piece 8a.

Further, the peripheral portion of the bolt through hole 9 in the mounting plate 8 is
The strength of the mounting plate 8 is strengthened by pressing it upward.

Reference numeral 13 denotes a positioning plate for the port, which is made of cardboard such as cardboard.

The positioning plate 13 has holes 14 at the four corners through which bolts are inserted, and the holes 14, 14 and 1 provided in the front and rear directions on both left and right sides.

Although the context is opposite to that described above, it is still within the scope of the present invention.

Further, in the above example, the through-holes 9 are thickened, but the through-holes 9 may not be provided as long as each elongated hole 11 of each horizontal piece 8a has enough strength to support the air conditioner. ,
The vertical pieces 8C of each mounting plate 8 are also not required to be installed depending on the position, and each nut 4 is inserted into each communication hole 10b and each insertion hole 12 provided at the rear end corners of the horizontal pieces Ba and Ba from an oblique direction. Although it is made so that it can be inserted, it may be made so that it can be inserted from above or from the horizontal direction, and various other design changes are possible without departing from the purpose of the present invention.

As explained above, the support device of the present invention has mounting plates 8 attached to both sides of the top plate 6 of the casing 5 in an air conditioner.

Since the position of the base hole is determined so that it can be inserted into the nuts 4, 4 (or rear), by supporting one side of the casing 5 in the long hole 11.11, the support weight of the entire air conditioner can be increased. is significantly reduced, and the anterior (or posterior) side
The insertion work is also extremely easy.

■ Like cutting, first insert the rear (or front) bolts and nuts, then the front (or rear) bolts/nuts to one side, then move the entire casing 5 horizontally backward (or forward) and insert each nut 4. All you have to do is support it in each elongated hole 11, and in the end, the entire installation work is difficult because the mounting bolts are installed in the ceiling, so it is difficult to install them at accurate pitches. In summary, the present invention is easy to install, does not require supporting heavy objects for long periods of time, and is less dangerous.

■Furthermore, since the rear parts (or front parts) of the horizontal pieces 8a, 8a are bent downward to form the bent pieces 8b, 8b, the horizontal pieces 8a, where the through holes closer to the bent pieces 8b, 8b are located. ,
Since the ends of the mounting plates 8a can be reinforced, the ends will not be deformed, and the mounting plates 8, 8 as a whole can be made more compact.
