Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shutter vane for a radiator for a vehicle or other vehicle.

This type of conventional radiator shutter, as shown in FIGS. 1 and 2, includes a rectangular frame 1, a pair of left and right vertical frames 2 fixed in the frame 1, and a space between the vertical frames 2 and 2. A pair of fixed upper and lower horizontal frames 3, a pair of operating rods 4 movably arranged along the vertical frames 2, 2, and two pins each provided at both ends are connected to the vertical frames 2 and 2, respectively. A plurality of vanes 5 are pivotally connected to the operating rod 4 and are pivotally supported in parallel between the vertical frames 2, 2 and between the operating rods 4, 4, and the operating rod 4.
and the frame 1, and gives the operating rod 4 the tendency to move upward, that is, in the direction of opening the vane 5. A spring 6 is fixed to the frame 1 and generates negative pressure from an engine (not shown). The vacuum actuator 7 is connected to a shutter stat and is controlled by a shutter stat (not shown), and is capable of moving the operating rod 4 downward, that is, in the direction of closing the vane 5, when activated.
The vane 5 is formed by drawing and forming a metal material such as iron or aluminum, and the vane body 8 is formed by processing the metal material, and is fitted into the hole 2a of the vertical frame 2 and the hole 4a of the operating rod 4, respectively. The vane body 8 is provided with two pins 9a and 9b that can
Since it consists of a pair of support arms 9 crimped to both ends of the shutter, it has the disadvantage that it is heavy, which in turn increases the weight of the entire shutter. or,
Since the vane main body 8 and the support arm 9 are molded separately, it is possible to avoid some errors in the attachment angle of each support arm 9 to each vane main body 8.
There was a problem in that all vanes 5 could not be completely closed when the shutter was closed. Furthermore, since the pins 9a and 9b, which are one of the two parts constituting the vane pivot joint, are made of metal, the mating member to which they are to be pivotally mounted, that is, the vertical frame 2,
If the operating rod 4 is made of metal, there is a problem in that when the vane 5 opens or closes or when vibrations due to the wind occur during running, a metallic sound is generated from the vane pivot point and the noise becomes high.

In view of the above-mentioned problems, the present invention integrally molds the vane main body and the support arm by molding a rigid resin material or press molding a thin metal plate such as an iron plate, and at the same time, the vane main body and the supporting arm are integrally formed by molding a rigid resin material or a thin metal plate such as an iron plate. The seal part is integrally molded with a flexible resin material, and the support arm has a hole or pin for the vane pivot, resulting in a radiator shutter vane that is lighter, has improved strength, improves sealing performance, and reduces noise. However, this will be explained below based on an embodiment shown in FIG.
3 are integrally molded, and the vane body 1
A seal portion 14 is integrally molded on the edge of the vane body 12 from a flexible resin material different from that of the vane body 12.
This is a vane in which a support arm 13 is provided with holes 13a and 13b for vane pivoting. Note that the vane main body 12 is provided with reinforcing ribs 12a.

The vane according to the present invention is constructed as described above, and since the entire vane is made of resin material, the weight of the entire shutter is reduced. Further, for the same reason, it is extremely easy to mold the shape into a shape that adapts to the flow of the wind, which also has the advantage of helping to reduce the resistance when opening the shutter. In addition, since the vane body 12 and the support arm 13 are made of a rigid resin material, and the seal portion 14 is made of a flexible resin material, they are integrally molded, so that the strength of the vane 11 is improved and at the same time the sealing performance is also improved. do. Furthermore, since the support arm 13 having the holes 13a and 13b, which is one of the two parts constituting the vane pivot joint, is made of resin, even if the mating member to which it is to be pivoted is made of metal, Metallic noise is no longer generated from the vane pivot point due to wind vibration when the vane 11 opens and closes or when the vane is running, which helps to reduce noise.

FIG. 4 shows a second embodiment, in which the support arm 1
The structure is the same as that of the first embodiment, except that pins 13c and 13d for vane pivoting are provided in place of the holes 13a and 13b in the third embodiment.

In both of the first and second embodiments, the vane main body 12 and support arm 13 can be molded using all the metal plates as a core to further strengthen the rigidity.

FIG. 5 shows a third embodiment, in which a vane body 16 and a support arm 17 are integrally molded by press-forming a thin metal plate such as an iron plate, and the vane body 16 is attached to the edge of the vane body 16. The seal portion 18 is integrally molded from a flexible resin material, and the support arm 17 has holes 17a, 17 for vane pivots.
b is an integrally molded vane. Therefore, since the vane 15 is made of a thin metal plate and a resin material, the weight of the entire shutter is reduced. In addition, since the vane body 16 and the support arm 17 are made of press-molded thin metal plates, and the seal portion 18 is made of a flexible resin material and integrally molded, the vane 15
This improves the strength and occlusion properties at the same time.

FIG. 6 shows a fourth embodiment, in which the support arm 1
The structure is the same as that of the third embodiment, except that pins 17c and 17d for vane pivoting are provided in place of the holes 17a and 17b.

As mentioned above, the vane of the radiator shutter according to the present invention has the important practical advantages of reducing the overall weight of the shutter, improving its strength, and at the same time improving its sealing properties and reducing noise.
