Abstract

PURPOSE:To fix a fin definitely at a required angle by connecting an interlocking plate with a free end which faces the inner surface of vertical bar of said fin with a pin and attracting an outer surface of said interlocking plate with a magnet. CONSTITUTION:A support metal fitting 2 which is horizontally U-shaped is fixedly installed to an outer side of vertical bars 1 where fins 3, which are mounted with the end with a pin 2B of the support metal fitting 2, are installed so that they may rotate freely. Furthermore, a plurality of magnets 4 are installed longitudinally to the vertical bars 1 on the inner side 1b of the vertical bars 1 of the fins 3. At the same time, an interlocking plate 5 is connected with a free end 3a which faces the inner side of the vertical bars 1 of the fins 3 with a pin 5a while the outside of the interlocking plate 5 is arranged to attracted by the magnets 4. This construction makes it possible to control the angle of the fins without any stage by fixing a movable part with the magnets 4. In this case, two fins can be moved by the interlocking plate 5 simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a louver fin used in an air conditioner outlet or the like.

"Conventional technology and its problems" For example, in a single-family prefabricated house, room heating,
Air conditioning, such as cooling, is performed using large air conditioners, and each room's air conditioning vents are equipped with louver fins that adjust the direction of hot or cold air blown out of the vents.

Conventional louver fins of this type have a large number of rotatable fins (blades) fitted inside the frame body that are fitted into the air conditioning outlet, and these louver fins are designed to move individually or in conjunction with each other. Nishishino is known.

However, such a louver fin has a problem in that there are many parts, and the screw fastening portion may become loose.

Additionally, those that do not use metal fittings and are fixed by the friction of the wood have a problem in that the rotating parts wear out over time and cannot be stopped at the desired angle.

The present invention has been made in order to solve the above-mentioned problems, and aims to provide a louver fin that is less likely to break by reducing the number of component parts and that can reliably stop the blades at a desired angle. The purpose is

"Means for Solving the Problem" In order to solve the above-mentioned problems, the present invention provides a pair of left and right vertical rungs, a supporting metal fitting fixed to the outer surface of these vertical rungs, and a vertical link between the vertical rungs and the vertical rungs. A plurality of fins are arranged along the longitudinal direction of the vertical run, and each end of the fin is rotatably attached to the end by a pin provided on a support fitting of the vertical run; An interlocking plate is connected by a pin to a plurality of magnets provided along the fin and a free end facing the inner surface of the longitudinal fin, and the outer surface side of the interlocking plate is attracted by the magnet.

"Function" In the present invention, the interlocking plate is connected to the free end facing the inner surface of the longitudinal side of the fin by a pin, and the outer surface side of the interlocking plate is attracted by the magnet, so that the pin of the support fitting is The free end side rotates steplessly as a fulcrum, and the rotating part does not wear out due to changes over time, and the free end side of the fin moves to a desired position.

"Embodiment" Hereinafter, one embodiment of the louver fin of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a perspective view of the louver fin of this embodiment, and in the figure, reference numeral 1 indicates a pair of vertical lateral fins provided on the left and right. A supporting metal fitting 2 formed in a U-shape is fixed to the outer surface 1a of the vertical suns 1, 1 with a pin 2a. A plurality of stages are arranged along the longitudinal direction of the longitudinal sill 1 between the longitudinal sills 1, 1, and support metal fittings 2 attached to the longitudinal sill 1 are provided.
A fin 3 is provided, the end of which is rotatably attached by a pin 2b. In this embodiment, two fins 3 are attached to one support fitting 2.

Furthermore, a plurality of magnets 4 are provided on the inner side 1b of the longitudinal sills 1, 1 along the longitudinal direction of the longitudinal sill 1, and an interlocking plate is provided at the free end 3a of the fin 3 facing the inner surface of the longitudinal sill 1. 5 are connected by a pin 5a, and the outer surface side of the interlocking plate 5 is attracted by the magnet 4. In this case, as in the case of the support fitting 2, 1
Two fins can be attached to each interlocking plate.

As shown in FIG. 2, the support fitting 2 is formed in a U-shape, has two screw holes, and has two screw holes inserted into holes 3b formed on the connection side of the fins 3. pin 2
b is provided. In this case, the external shape of pin 2b is hole 3
By making the diameter smaller than the inner diameter of pin 2b, pin 2b fits into hole 3.
It is rotatable within b.

In addition, a push-through hole 1 is provided on the side surface of the vertical zang, into which a magnet 4 is inserted near the center of the support fitting 2 fixed to the side surface of the vertical zang.
The connecting plate 5 has two pins 5 that are pushed into each hole 3C provided on the free end side of the fin 3.
The configuration includes a. In this case, pin 5a
The outer diameter of the pin 5a is smaller than the inner diameter of the hole 3C, so that the pin 5a can freely rotate inside the hole 3.

In the case of this embodiment, the shape of the fin is such that, as shown in FIG. 4, a 45° inclined surface 3d is formed at the free end of the fin (on the right side with respect to the plane of the paper in FIG. 4). That is, in a wall-mounted air conditioner, it is necessary to send air downward during heating and horizontally when cooling. Therefore, during cooling, the fins take on a horizontal shape as shown by the solid line in FIG. 4, and during heating, the fins take on a rotated shape as shown by the two-dot chain line. However, in the case of wood-based fins, a certain thickness is required, so with conventional fins without a sloped surface, the flow path becomes narrow during heating and obstructs the airflow. Ta. Therefore, by providing the 45° inclined surface 3d on the free end side of the fin as in this embodiment, even when the fin is rotated, the obstruction of the air passage is minimized and heating efficiency can be increased. Become.

Next, a method of assembling the louver fin of this embodiment will be explained.

First, the support fitting 2 is fixed to the outer surface of the vertical sill 1 with screws 2a.

Next, the magnet 4 is inserted into the insertion hole IC, and the pins 5a, 5a of the connection plate 5 are respectively inserted into the holes 3C of the two fins to connect the two fins 3, 3.

Next, the pin 2b of the support hardware 2 fixed to the vertical sill l,
2b into the holes 3c, 3c of the two fins 3, the assembled shape as shown in FIG. 3 is obtained.

In this way, according to the louver fin of this embodiment, the angle of the fin can be adjusted steplessly by fixing the movable part with a magnet. And in this case, 2
The fins can be moved simultaneously by interlocking plates.

In the above embodiment, the two fins are interlocked using the interlocking plate, but the invention is not limited to this, and the interlocking plate may be made longer and two or more pins may be provided thereon to interlock the two fins. The plurality of fins described above can be driven in conjunction with each other.

"Effects of the Invention" As described above, according to the louver fin of the present invention, the support metal fittings fixed to the outer surface of the vertical sills and the support metal fittings arranged between the vertical sills and the louver fins of the vertical sills. a fin whose end portion is rotatably attached by a pin provided on a support fitting; a plurality of magnets provided on the inner surface of the vertical sill along the longitudinal force direction of the vertical sill; The interlocking plate is connected to the free end facing the inner surface with a pin, and the outer surface of the interlocking plate is attracted by the magnet, so even if the fulcrum of the fin loosens due to drying of the wood, the magnet will not displace it. The fixing method allows the fin to be securely stopped at the desired angle, the small number of crystal parts makes it difficult to break, and the wood is processed to be R11 pure, making it easy to assemble. play.
