Abstract

PURPOSE:To make it possible to adjust the positional relationship between a main body and a duct easily even under a condition wherein the position of a duct is determined by a method wherein to an adapter which is made of a cylindrical shaped sheet metal or resin, and is attached to a main body, a flange part is equipped, and on the flange part, cross shaped screw holes which are formed into a cross shape are provided. CONSTITUTION:At several spots on the periphery of a flange part 7 of an adapter 5 which is made of a sheet metal or resin, cross shaped screw holes 13 which are formed into a cross shape are provided so that moving of the adapter 5 is available in a considerably wide range, and the adapter 5 is fixed by fixing screws 14. When a cut part on a ceiling surface 9, which is previously determined, and the position of a suspended main body 1 are different, suspending bolts 3 and a duct 4 are adjusted. When the duct 4 cannot be moved, the fixing screws 14 for the adapter 5 are loosened, and the position of the adapter 5 is moved and adjusted to the duct 4, and the adapter 5 is fixed again by the fixing screws 14. Thus, it is constituted to connect a duct by making it possible to move an adapter by providing cross shaped screw holes, and therefore, it is not required to redo a duct installation, and construction work becomes much easier.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an adapter that connects to a duct connected between the main body of an air conditioner or the like and an indoor air outlet.

2. Description of the Related Art Conventionally, when a main body of a ventilation air conditioning unit such as UniSoto is installed in the attic of an apartment complex to provide ventilation and air conditioning, a duct connected to the main body is provided to carry out intake and exhaust air. The main body and the duct are connected as shown in FIGS. 3 and 4. In other words, the main body 1 of the ventilation air conditioning unit
is installed by a hanging fitting 2 and a hanging bolt 3. For example, an intake duct 4 is provided on one side of the main body 1.
An adapter 6 for connection is installed from inside the room and is fixed with screws 6. The adapter 6 is composed of a collar part 7 for fixing with the screw 6 and a cylindrical part 8, and is connected to the outer periphery of the cylindrical part 8 by fitting into the inner periphery of the duct 4. In addition, as shown in Fig. 4, the sea urchin body 1 is embedded in the attic 10 above the ceiling surface 9 and is connected to the duct 4. A panel/l/11 was connected to the lower part of the main body 1, and air was blown into the room from the cassette panel 11.

Problems to be Solved by the Invention In such a conventional configuration, the pasting work on the ceiling surface 9 is completed, the installation by hanging the main body 1 is also completed, and the duct 4
The installation of the cassette panel 11 is completed until it reaches near the main body 10, and in the final construction, the ceiling surface is cut out to match the ceiling surface 9 and the main body 1, and the cassette panel 11 is to be joined to the main body 1. However, in practice, the ceiling surface 9 is cut open and the cassette panel 10 and the main body 1 are joined almost in alignment, so the adapter 6 of the Ruruka main body 1 and the duct 4 do not match well, and the duct 4 Since the adapter 6 and the duct 4 are held and fixed in the attic, it is often difficult to connect the adapter 6 and the duct 4 because they are misaligned with each other.The connection between the adapter 6 and the duct 4 is made by modifying the duct 4 that is already fixed. However, there was a problem in that it took time and effort to correct the misalignment and make connections.

The present invention solves the above-mentioned conventional problems, and aims to provide an adapter that allows the positional relationship between the main body and the duct to be easily adjusted even when the position of the duct has been determined.

Means for Solving the Problem In order to solve this problem, the present invention has a cylindrical sheet metal or resin having a flange portion in which one end face is widened into a donut shape, and the flange portion has several parts. A cross-shaped hole is provided, the center of which is located at the center of the plane portion, and is provided on a constant circumference.

With this configuration, if there is a misalignment between the adapter and the duct, the position of the adapter can be moved and connected using the cross-shaped screw hole, and the adapter with the screw hole in the other embodiment can be connected. As appropriate, use the screw holes to position and connect to the duct.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2, and the same reference numerals used in the conventional example indicate the same thing.
Explanation will be omitted. That is, the flange 7 of the adapter 5 made of sheet metal or resin is provided with cross-shaped screw holes 13 at several places around the circumference, so that the adapter 6 can be moved relatively widely, and the fixing screws 14 to fix the adapter 6. In the above configuration, if the predetermined cut part of the ceiling surface 9 and the position of the suspended wooden body 1 are different, the hanging bolts 3 and the duct 4 will have to be adjusted, but if the duct 4 does not move, , adapter 6
Loosen the fixing screw 14 and adjust the position of the adapter 6 to the duct 4.
It is moved in accordance with the movement and then fixed again with the fixing screw 14. FIG. 3 shows another embodiment, in which a large number of screw holes 16 are provided in the collar 7 of the adapter 5 in the form of punching, and while the adapter 6 is moved, the duct 4 You move it while adjusting its position until it's in the right position.

As a result, the large number of screw holes 16 allows adjustment to be made no matter which screw hole 16 is selected, and this adjustment has a wider adjustment range than the first embodiment and improves workability.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a cross-shaped screw hole in the flange of the adapter attached to the main body to enable movement of the adapter and connect it to the duct. Because of this structure, even if the duct does not move, it can be easily adjusted by adjusting the adapter, and there is no need to redo the duct work, making the construction easier. Also,
By providing a large number of screw holes in the flange, the adjustment range is expanded, and the connection can be made even if the positions of the duct and the adapter are greatly misaligned.
