Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air-conditioning grill installed in an instrument panel or the like at the front of an automobile.

[Prior Art] Conventionally, air conditioning grilles installed in the instrument panel of automobiles have been constructed with a wind deflection plate made of an elastic plate spring material such as metal, rubber, or resin. It has been proposed to change the direction of the wind by curving it into an arc.

For example, as shown in FIGS. 7 and 8, the front end of the main body case 20 is
Four bendable wind direction deflection plates 21 that are pivotally supported are arranged. The left and right rear end portions of the wind deflection plates 21 are fixed to a pair of connecting rods 22 that connect the four wind deflection plates 21. Further, at the upper left side inside the main body case 20, an operating lever 23 is provided, one end of which is pivotally supported by the connecting rod 22, and the other end of which is pivotally supported by the main body case 20. Furthermore, a rod 24 is provided below the operating lever 23 and has one end pivoted on the connecting rod 22 and a middle section pivoted on the main body case 20, and forms a parallel link with the operating lever 23. ing.

By rotating the operating lever 23 in the vertical direction, the connecting rod 22 is moved up and down, and the wind direction deflecting plate 21 is curved.

[Problems to be Solved by the Invention] In the conventional air conditioning grill described above, in order to change the wind direction by curving the wind direction deflecting plate 21, the operation lever 23 located at the upper left end inside the main body case 20 is used. 23 position and wind direction deflection plate 2
The problem is that when the wind deflection plate 21 is curved, the wind deflection plate 21 is twisted or distorted because the wind deflection plate 21 is bendable. The dot was hot.

In addition, in order to solve this problem, increasing the strength and rigidity of each member or increasing the accuracy of bearings, etc., resulted in problems such as an increase in the weight of the entire air conditioning grill and an increase in manufacturing cost.

The purpose of this invention is to solve the above-mentioned problems, and to provide an air conditioning grill that can be operated with light operating force, does not twist or distort when the wind deflection plate is curved, has little increase in weight, and is low in manufacturing cost. It is about providing.

[Means for solving the problem] In order to achieve the above object, the present invention arranges a plurality of bendable wind deflection plates in the main body case,
One end of the wind deflection plate is pivotally supported on the main body case, and the other end is connected to a pair of connecting rods to which the plurality of wind deflection plates are connected, and the wind deflection plate is connected between the same pair of connecting rods or between the plurality of wind deflection plates. A bridging member is bridged between the plates, and an operating member is provided with an operating point approximately at the center of the bridging member and a shaft provided in the main body case as a fulcrum, and one end of which is supported by a shaft on each of the pair of connecting rods. A configuration is adopted in which a pair of rods are provided as parallel links, the other end of which is pivotally supported by the main body case.

[Function] By adopting the above configuration, when the operation member is rotated around the fulcrum, the bridge member rotates together with the point of action of the operation member located at the center of the bridge member, and at the same time, the bridge member rotates as a parallel link. Due to the action of the pair of rods, an equal force is applied to the pair of connecting rods, and the connecting rods rotate effortlessly, causing the wind deflection plate to curve smoothly, so that the wind from the rear of the air conditioning grill is curved. It flows along the wind deflection plate and blows out in a predetermined direction from the front end of the air conditioning grill.

[First Embodiment] An embodiment in which the present invention is applied to an air conditioning grill mounted on an instrument panel inside an automobile will be described below with reference to FIGS. 1 to 3.

As shown in Fig. 3, the rectangular parallelepiped main body case 1
Inside, four bendable wind deflection plates 2 are arranged. The bendable wind deflection plate 2 may be made of rubber such as chloroprene rubber, synthetic resin such as polyvinyl chloride, polypropylene, polyethylene, or metal such as stainless steel.

As shown in FIG. 1, the front end of the wind deflection plate 2 is attached to a
It is rotatably supported on a book shaft 3. A pair of connecting rods 4 for connecting the four wind deflection plates 2 are provided at both rear ends of the wind deflection plates 2. The pair of connecting rods 4 each have a shaft 5 attached to the rear end portion of the wind deflecting plate 2 .

Above and below each connecting rod 4, one end is connected to the same connecting rod 4.
A pair of rods 6 are each provided, the other end of which is pivotally supported by the main body case 1, and each of the pair of rods 6 constitutes a parallel link.

As shown in FIG. 1 or 2, a round bar-shaped bridging member 7 is spanned approximately at the vertical center between the pair of connecting rods 4. As shown in FIG. The rear end of the bridging member 7 is pivotally supported at approximately the center thereof to serve as a point of action 9, and its intermediate portion is supported by a shaft 10 fixed to the main body case 1 and serves as a fulcrum 11, serving as an operating member. An operating lever 8 is provided.

The functions and effects of the air conditioning grill configured as described above will be explained.

First, as shown in FIG. 1, when the operating lever 8 is rotated upward, the operating lever 8 rotates about the fulcrum 11, and the operating point 9 at the rear end rotates downward. Then, since the bridging member 7 is connected to the operating lever 8 at the same point of action 9, it rotates downward in the same way as the point of action 9. Moreover, since the bridging member 7 is bridged between the pair of left and right connecting rods 4, both of these connecting rods 4 also rotate downward. At this time, both connecting rods 4 are rotated smoothly and reliably by a parallel link mechanism of a pair of rods 6 provided respectively. At this time, the operating force (rotational force) from the operating lever 8 is applied to both connecting rods since the point of action 9 of the operating lever 8 is located approximately at the center of the bridging member 7.
is transmitted evenly.

The rear ends of the four wind deflection plates 2 are attached to both connecting rods 4 with shafts 5, so that each wind deflection plate 2
is curved downward in a convex shape about the axis 3 at its front end. As mentioned above, both connecting rods 4 have
Since the operating force from the operating lever 8 is evenly distributed and applied, a uniform force is applied to the rear ends of the four wind direction deflection plates 2 via the shaft 5 as a whole. Therefore, the operating force of the operating lever 8 is light, and each wind direction deflection plate 2
There is no twisting or distortion, and the whole curves smoothly around its front end.

In this state, the wind from the rear of the main body case 1 flows smoothly upward along the curved state of each wind direction deflecting plate 2, and is blown upward from the front end of the main body case 1.

Next, when the operating lever 8 is rotated downward in the opposite direction to the above, the bridging member 7 and the like move in the opposite direction to the above, so that each wind direction deflecting plate 2 curves upward and into a convex shape. Therefore, the wind from the rear of the main body case 1 is blown downward from the front end of the main body case 1, thereby maintaining the interior of the automobile in a comfortable state.

As described above, in the air conditioning grill of this embodiment, the operating lever 8 can be operated with relatively light force. Moreover, when the wind direction deflecting plate 2 is curved, it is not twisted or distorted. Furthermore, since it is only necessary to provide the bridging member 7, etc., the weight of the air conditioning grill does not increase much, and the manufacturing cost can be reduced.

[Second Embodiment] Next, another embodiment in which the present invention is applied to an air conditioning grill mounted on an instrument panel inside an automobile will be described with reference to FIGS. 4 to 6.

As shown in FIG. 6, the front part of the rectangular parallelepiped-shaped ventilation duct 12 with holes in the front and back has three holes in the horizontal direction.
Non-curving rigid resin wind deflection plate 1
A main body case 1 having a main body case 3 is disposed. The main body case 1 is rotatably supported by the air duct 12 via a shaft 14.

Behind the wind deflection plate 13, as shown in FIG. 4, four other bendable wind deflection plates 2 are arranged at approximately equal intervals in the vertical direction perpendicular to the wind deflection plate 13. . At the front end of the wind deflection plate 2,
It is supported by a shaft 3 fixed between flat holding plates 15a and 15b integrally arranged on the upper and lower sides of the main body case 1 and a wind direction deflection plate 2.

Therefore, the coaxial 3 is attached to these holding plates 15a and 15b.
and the wind direction deflection plate 2 are reinforced at four places, respectively, so that the wind direction deflection plate 2 can be reliably bent. Further, the rear end portion is fixed to a shaft 17 provided on a connecting rod 4 that connects the four wind deflection plates 2 above and below.

On the rear extension line of the four wind deflection plates 2, another wind deflection plate 18 made of resin and having rigidity that does not curve is disposed integrally with the upper and lower connecting rods 4. The front end of the wind deflection plate 18 is connected to the shaft 17.
is fixed to the wind W from the rear of the air duct 12.
and are always in the same direction. The wind deflection plate 18 is supported by a shaft 17, and each of the four shafts 17 is reinforced by the wind deflection plate 18, which prevents the wind deflection plate 2 located in front of it from bending. I've learned not to do that.

As shown in FIGS. 4 and 5, a bridging member 7 connecting the four wind deflection plates 2 is provided horizontally at the rear end of the wind deflection plate 2, approximately in the center in the vertical direction. ing. The rear end of the bridging member 7 is pivotally supported at approximately the center thereof to serve as a point of action 9, and its intermediate portion is supported by a shaft 10 fixed to the main body case 1 and serves as a fulcrum 11, serving as an operating member. An operating lever 8 is provided. The operating lever 8 is formed so as to sandwich the wind direction deflecting plate 13 from above and below.

Furthermore, a pair of rods 6 are provided above and below both ends of the connecting rod 4, with one end being pivotally supported by the connecting rod 4 and the other end being pivotally supported by the main body case 1,
The pair of rods 6 constitute a parallel link.

When the operating lever 8 is rotated left and right from the front of the main body case 1, the operating lever 8 is rotated left and right about the fulcrum 11, and the connecting rod 4 connected at the point of action 9 is moved in the opposite direction. The wind direction deflecting plate 2 is curved between the front and rear shafts 3 and 17. At this time, the axis 17 of the wind deflection plate 2
The side end portions are arranged in the same direction as the wind W from the rear of the ventilation duct 12.

The wind direction deflecting plates 2, 13, 18, connecting rod 4, bridging member 7, holding plates 15a, 15b, etc. disposed in the air duct 12 are integral with the main body case 1, and are integrally formed around the shaft 14. It is designed to rotate up and down.

The functions and effects of the air conditioning grill configured as described above will be explained.

First, as shown in FIG. 4, when the operating lever 8 is moved to the right from the center to a predetermined position, the operating lever 8 rotates around the fulcrum 11, so that the rear end of the operating lever 8 The bridging member 7 connected at the point of action 9 moves to the left. And the wind direction deflection plate 2
The shaft 17 of the connecting rod 4 is used as one fulcrum, and the shaft 3 is used as the other fulcrum, and curves protrudingly toward the left.

Further, the wind direction deflection plate 18 located behind the wind direction deflection plate 2 maintains the same direction in the front-rear direction. Therefore, the wind W from the rear of the air duct 12 passes through the wind deflection plate 18 and smoothly flows to the right along the curved wind deflection plate 2.

Also, when the main body case 1 is rotated upward around the shaft 14, the wind deflection plates 2, 13, 1
An integrated object such as No. 8 also rotates upward. Then,
The wind W from the wind direction deflection plate 2 located at the rear is as follows:
The air flows upward along the wind deflection plate 13.

When the operating lever 8 is moved to the left in the opposite direction to the above, the connecting rod 4 is moved to the right, and the wind direction deflection plate 2 is curved to the right in a convex shape. Further, the wind direction deflecting plate 18 maintains its front-rear direction. Therefore, the wind W from the rear of the ventilation duct 12
flows to the left along the wind deflection plate 2 via the wind deflection plate 18.

As described above, in the air conditioning grill of this embodiment, the point of action 9 of the operating lever 8 is located approximately at the center of the bridge member 7, and the operating force of the operating lever 8 is applied to the rear end of the four wind deflecting plates 2. Since the force is transmitted evenly to the connecting rod 4 and the connecting rod 4, the operating lever 8 can be operated with a relatively light force. In addition, the shaft 1 at the rear end of the wind direction deflection plate 2
Since an even force is reliably transmitted to the wind deflection plate 7, the wind direction deflection plate 2 is curved continuously and smoothly, and no twisting or distortion occurs. In addition, since it is sufficient to simply provide members such as the bridging member 7, the weight of the air conditioning grill does not increase much, and the manufacturing cost can be reduced.

Note that the wind W of the wind direction deflection plate 18 and the wind direction deflection plate 2
Since the introduction side end is in the same direction as the direction of the wind W introduced from the blower duct 12, noise generation is reduced.

In addition, by operating the operating lever 8 in the left and right direction, the wind W can be blown out in the left and right directions, and by rotating the main body case 1 in the up and down direction, the wind W can be blown out in the up and down directions. Therefore, the wind W can be easily blown out in any desired direction, up, down, left, or right.

The present invention is not limited to the above embodiments, but may be configured as follows.

(1) In the air conditioning grill of the present invention, the position of the bridging member 7 that spans between a pair of connecting rods 4 or between a plurality of wind deflection plates 2 does not necessarily have to be in the center, and may be placed depending on the structure. can be set at the appropriate position.

(2) In the air-conditioning grill of the present invention, the wind direction deflection plate 2 can be provided vertically in the structure of the first embodiment, and the wind direction deflection plate 2 can be provided in the vertical direction in the structure of the second embodiment. The deflection plate 2 may be arranged horizontally, and the wind direction deflection plate 13 may be arranged vertically. Furthermore, the number of wind deflection plates 2, 13 can be set as appropriate for any structure.

(3) The air conditioning grill of the present invention can be used not only as an outlet for an automobile instrument panel as in each of the embodiments described above, but also as an outlet for a household heater or air conditioner.

[Effects of the invention] The air conditioning grill of this invention can be operated with light operating force, does not twist or warp when the wind deflection plate is curved, and has the advantages of little weight increase and low manufacturing cost. It has a great effect.
