Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling opening device which indicates the position of a ceiling opening of an air conditioner when the air conditioner is to be embedded and installed in the ceiling.

[0002]

2. Description of the Related Art In recent years, a so-called built-in type in which an air conditioner is embedded in a ceiling is rapidly advancing in order to effectively use a living room and improve its appearance. However, in the installation work of the built-in type air conditioner, the installation work cannot be shortened and the finished state cannot be improved unless there is a work procedure and work with the building side, and these improvements have become necessary.

Conventionally, as shown in FIGS. 4 and 5, this type of mounting is known. Here, in order to show the position of the ceiling opening 6a, the ceiling opening indicating plates 5 are fixed to the air conditioner main body 1a at four locations of the main body corner 1b with screws 7, respectively.

[0004]

However, in such a conventional structure, the air conditioner body 1a has the ceiling surface 6d.
Since the ceiling opening indicating plate 5 is also mounted deeper in the back, the carpenter performing the ceiling assembly may forget to provide the ceiling opening 6a. In such a case, there is a problem in that it takes time to work the ceiling opening 6a after the ceiling assembly is completed and the work is post-processing, so that the finish of the ceiling opening 6a becomes dirty.

Further, the conventional ceiling opening indicating plate 5 has a body corner 1
Since there are only four positions of b, the instruction on the way is the virtual line 5a, so the ceiling opening 6a protrudes inward and outward from the virtual line 5a, which cannot be performed cleanly and accurately.

It is an object of the present invention to provide a ceiling opening device that can shorten the installation work and improve and improve the finished state.

[0007]

A ceiling opening device according to a first aspect of the present invention includes an opening wooden frame 10 indicating a position of a ceiling opening portion of an air conditioner 1 of an air conditioner body 1a of the air conditioner 1. The opening wooden frame is fixed to a mounting screw hole 21 for fixing the ceiling panel 8.

The ceiling opening position according to claim 2 is such that a ceiling line 13 indicating the positional relationship between the air conditioner main body 1a and the ceiling surface 6d is provided around the opening wooden frame 10, and the air conditioning unit is provided in the opening wooden frame 10. The lower fixing nut 12 of the suspension bolt 3 for fixing the main body 1a is provided with a through hole 22 which enables the vertical movement.

[0009]

According to the first aspect of the present invention, the opening wooden frame 10 is fixed to the mounting screw hole 21 for fixing the ceiling panel 8 of the air conditioner body 1a.

As a result, since the opening wooden frame 10 is exposed downward from the ceiling surface 6d, a carpenter who performs ceiling assembly will not forget to provide the ceiling opening 6a.

Next, according to the second aspect of the present invention, the opening wooden frame 1 is provided.
A ceiling wire 13 indicating the positional relationship between the air conditioner body 1a and the ceiling surface 6d is provided around 0, and the lower fixing nut 12 of the hanging bolt 3 for fixing the air conditioner body 1a to the opening wooden frame 10 can be moved up and down. By providing the through hole 23, the wrench tool 24 for vertically moving the nut 12a is provided with the through hole 25.
Pass through the ceiling wire and rotate it up and down to move the ceiling wire 1
3 can be easily fitted to the ceiling surface 6d.

As a result, the ceiling panel 8 becomes the air conditioner body 1
Both a and the ceiling surface 6d are mounted without a gap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The ceiling opening device of the present invention will be described below with reference to FIGS.

Elements having the same functions as those of the conventional example shown in FIGS. 5 to 6 will be described with the same reference numerals.

Numeral 10 is an opening wooden frame showing the position of the ceiling opening 6a of the air conditioner, and an opening plate 10a having a vertical width.
It has a shape that surrounds. Further, the opening wooden frame 10 is provided with mounting plates 10b for fixing to the air conditioner body 1a on both sides of the opening wooden frame 10, and the ceiling panels 8 provided on the air conditioner body 1a are fixed to the mounting plates 10b. A mounting hole 22 is provided for fixing using the mounting screw hole 21. Reference numeral 23 denotes a screw screw for fixing the opening wooden frame 10.

Further, around the opening plate 10a, the ceiling surface 6 when the opening wooden frame 10 and the air conditioner body 1a are integrated with each other.
A ceiling line 13 indicating the vertical positional relationship of d is provided.

Further, the mounting plate 10a is provided with a through hole 25 through which the range tool 24 penetrates in order to vertically move the fixing nut 12 of the suspension bolt 3.

Next, the operation of the configuration of this embodiment will be described. A carpenter who assembles the ceiling assembles the ceiling frame 6c and the ceiling 6 in this order along the outer periphery of the opening plate 10a.
a can be easily provided.

Further, since the opening wooden frame 10 is exposed downward from the ceiling surface 6d, the ceiling opening 6a is not forgotten.

Further, a wrench tool 24 for vertically moving the lower fixing nut 12 is passed through the through hole 25, and the wrench tool 24
It is possible to easily align the ceiling wire 13 with the ceiling surface 6d while rotating the hand and moving it up and down.

As a result, the ceiling panel 8 becomes the air conditioner body 1
Both a and the ceiling surface 6d are mounted without a gap.

[0022]

According to the structure of the first aspect, the opening crate showing the position of the ceiling opening of the air conditioner is fixed to the mounting portion for fixing the ceiling panel of the air conditioner body. Therefore, a carpenter who assembles a ceiling can easily assemble the ceiling frame and the ceiling along the outer periphery of the opening plate in order to provide the ceiling opening.

Further, since the opening wooden frame is exposed downward from the ceiling surface, the ceiling opening will not be forgotten.

Further, since the work of opening the ceiling is performed at the same time as the assembling of the ceiling, the finish can be cleaned accurately.

According to the structure of claim 2, a ceiling wire is provided around the opening wooden frame to indicate the positional relationship between the air conditioner body and the ceiling surface, and the suspension bolt of the air conditioner body is fixed to the opening wooden frame. With a through hole that allows the fixing nut to move up and down, a wrench tool that moves the fixing nut up and down is passed through the through hole, and the wrench tool is turned up and down to easily move the ceiling wire to the ceiling surface. Can be adjusted to

As a result, since the ceiling panel is attached to the air conditioner main body and the ceiling surface without any gap, it is possible to prevent the occurrence of dew condensation due to cold air leakage.

As described above, the present invention makes it possible to shorten the installation work and improve and improve the finished state.
