Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to an air conditioning grill installed in the interior of an automobile.

(Conventional technology) Conventionally, air conditioning grilles installed mainly on instrument panels inside automobiles have been constructed with wind direction changing plates made of thin leaf spring material, or configured in a shape that is easy to curve. Then, this wind direction changing plate is deformed into an arc shape and installed inside the case.
There is a device in which the wind direction can be changed by applying pressure to the wind direction changing plate and changing the arc direction of the wind direction changing plate from side to side (Japanese Utility Model Publication No. 51-2849).

As shown in FIG. 7, for example, there is a type of wind direction changing plate in which V-shaped slits 22 are formed at equal intervals on the upper and lower surfaces of the wind direction changing plate 21 to make it easier to bend. 51-6643).

(Problem to be solved by the invention) In the conventional air conditioning grill mentioned above, the force from the operating lever that changes the wind direction is not evenly transmitted to the entire wind direction change plate, which causes the wind direction change plate to twist and cause the wind to flow. This creates turbulence and creates vortices, which creates noise and impairs the direction of the wind. Further, in the wind direction changing plate 21 having the shape shown in FIG. 7, there are problems in that the unevenness of the slits 22 disturbs the flow of the wind, generates noise, and worsens the direction of the wind.

Structure of the invention (means for solving the problems) In order to solve the above problems, the present invention has a plurality of bendable wind direction adjusting plates arranged inside the main body case, and one end of the wind direction adjusting plates is One end of the wind direction adjustment plate is pivotally supported within the main body case to serve as a curved fulcrum, and the other end is pivotally supported on a connecting rod to which the plurality of wind direction adjustment plates are connected and movable by an operating means. An air conditioning grill that serves as the other curved fulcrum of a wind direction adjustment plate, wherein the wind direction adjustment plate is made of a soft material,
A means is adopted in which at least the shaft portions at both supporting points are made of a rigid body over the entire length of the wind direction adjusting plate.

(Function) By adopting the above means, since the wind direction adjustment plate is made of a soft material, it can be freely curved in a predetermined direction between its two supporting points, so that the wind from the rear of the main body case can be directed to the wind direction adjustment plate. The flow gradually changes direction along the curved part and blows out from the front end of the main body case, and the shafts at both fulcrums of the wind direction adjustment plate are made of a rigid body over the entire length of the wind direction adjustment plate. The rigid body of the wind direction adjustment plate has sufficient rigidity in a certain direction, and the entire wind direction adjustment plate is difficult to twist.

(Example) Hereinafter, an example in which the present invention is embodied in an air conditioning grill attached to an automobile instrument panel will be described with reference to FIGS. 1 to 4.

As shown in FIGS. 1 and 2, the air conditioning grill of this embodiment has four bendable wind direction adjustment plates 2 arranged vertically and equidistantly in a rectangular parallelepiped main body case 1 with holes at the front and rear. One end of each wind direction adjustment plate 2 is rotatably supported on the main body case 1 by a shaft 3 at a position slightly behind the front end inside the main body case 1, and serves as one fulcrum of each wind direction adjustment plate 2. ing.

Here, the wind direction adjustment plate 2 will be explained. The material of the wind direction adjustment plate 2 is a soft material S that is easy to bend, and synthetic resins such as olefin resins such as polypropylene, vinyl chloride resins, and urethane resins, and elastic bodies such as solid rubber and sponge rubber are used. .

Further, as shown in FIGS. 3 and 4, the shaft portions 3 and 5 at both ends of the wind direction adjustment plate 2 are made of a rigid body G over the entire length of the wind direction adjustment plate, and the rigid body G is made of aluminum. Metals such as, hard resins such as hard vinyl chloride resin, hard rubber, etc. are used. The wind direction adjusting plate 2 is manufactured by inserting or insert molding the rigid body G into the soft material S formed into a predetermined shape, but insert molding is preferable from the viewpoint of ease of manufacturing. suitable. This rigid body G prevents the entire wind direction adjustment plate 2 from being twisted, and exhibits sufficient rigidity in the horizontal direction of the wind direction adjustment plate 2 (the direction in which the rigid body G is located).

In addition, this rigid body G has, in addition to the above-mentioned shaft parts 3 and 5,
Any number of pieces can be placed at any position between the shaft parts 3 and 5 of the wind direction adjustment plate 2 (in Figures 3 and 4, 3 pieces are placed at equal intervals).
location) can be provided. In this way, the rigid body G
The above effect is further promoted by increasing the number of .

Next, at the other end of the wind direction adjustment plate 2, a connecting rod 4 on which four wind direction adjustment plates 2 are supported on shafts 5 at equal intervals is vertically provided, and the shaft portion 5 of each wind direction adjustment plate 2 is It serves as the other fulcrum of the wind direction adjustment plate 2. In the position shown in FIG. 1, this wind direction adjustment plate 2 is curved downward between both shaft parts 3 and 5, and the wind W from the rear of the main case 1 hits the wind direction adjustment plate 2 and is directed upward along the curved part. It's starting to blow out.

When the connecting rod 4 is located above the position shown in Fig. 1 and the wind direction adjustment plate 2 is horizontal, the wind direction adjustment plate 2 has its natural length, and the straight distance between the shaft parts 3 and 5 is at its maximum. It's getting longer. In addition, at the end of the wind direction adjustment plate 2 on the shaft 5 side, the direction is the same as the direction (horizontal direction) of the wind W introduced from the rear of the main body case 1, regardless of the vertical position of the connecting rod 4. There is.

When the connecting rod 4 moves further upward, the linear distance between the shaft parts 3 and 5 of the wind direction adjustment plate 2 gradually decreases, the wind direction adjustment plate 2 curves upward, and the wind W from the rear of the main case 1 is reduced. The air hits the wind direction adjustment plate 2 and blows out downward along the curved portion thereof.

Further, at the left end in the horizontal direction inside the main body case 1, one end is rotatably supported by the central shaft part 7 of the connecting rod 4, and the other end is supported by the wind direction adjusting plate 2.
An operating lever 6 serving as an operating means is provided rotatably supported at a fulcrum 8 located rearward of the shaft portion 3 . The shaft portion 7 and fulcrum 8 of the operating lever 6
The distance in the natural length (horizontal direction) between them is set to three-fourths of the distance in the natural length (horizontal direction) between both shaft parts 3 and 5 of the wind direction adjustment plate 2.
By operating the operating lever 6 in the vertical direction, the operating lever 6 rotates around the fulcrum 8, moves the connecting rod 4 up and down, and changes the bending direction of the wind direction adjustment plate 2. It's getting old.

At the bottom of the operating lever 6, one end is rotatably supported on the shaft portion 10 of the connecting rod 4, and the other end is supported on the main body case at a fulcrum 11 located at the same longitudinal position as the fulcrum 8 of the operating lever 6. An auxiliary rod 9 supported by the lever 1 is provided parallel to the operating lever 6. The auxiliary rod 9 rotates parallel to the operating lever 6 around the fulcrum 11 in accordance with the movement of the operating lever 6, and assists the wind direction adjusting plate 2 so that the four wind direction adjusting plates 2 move in a smooth arc. I am definitely learning to draw.

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

First, as shown in FIGS. 1 and 2, when the operating lever 6 on the front left side of the main body case 1 is in a substantially horizontal state, the wind direction adjustment plate 2 is also in a horizontal state and reaches its natural length. ing.

Next, when the operating lever 6 is operated upward, the operating lever 6 rotates around the fulcrum 8, its shaft portion 7 moves downward, and the connecting rod 4 connected to the coaxial portion 7 also moves downward. do. Therefore, the shaft portion 5 of the wind direction adjusting plate 2 is connected and fixed to the connecting rod 4, and since the wind is sent from the rear of the main body case 1, the wind direction adjusting plate 2 curves downward. At this time, since the wind direction adjustment plate 2 is made of a soft material S, it can be easily bent downward, and
Since the shaft parts 3 and 5 are formed of the rigid body G, they have sufficient rigidity in the left and right direction where the rigid body G is provided, and the entire wind direction adjustment plate 2 is difficult to twist. Further, the fulcrum 8 of the operation lever 6 is located further back than the shaft 3 of the wind direction adjustment plate 2, and the distance between the shaft 7 of the operation lever 6 and the fulcrum 8 is longer than the distance between the shafts 3 and 5 of the wind direction adjustment plate 2. Since the distance between the shafts 3 and 5 is shorter, as the connecting rod 4 moves downward, the straight line distance between the shaft parts 3 and 5 of the wind direction adjustment plate 2 gradually becomes shorter, and the degree of curvature of the wind direction adjustment plate 2 increases. Become. In this case as well, the wind direction adjustment plate 2 easily follows the degree of curvature, and the wind direction adjustment plate 2
The whole thing is hard to twist.

As mentioned above, the distance in the natural length (horizontal direction) between the shaft portion 7 of the operating lever 6 and the fulcrum 8 is equal to the distance in the natural length (horizontal direction) between both shaft portions 3 and 5 of the wind direction adjustment plate 2. Since it is set to 3/4, regardless of the curved state of the wind direction adjustment plate 2, the end on the shaft portion 5 side is in the same direction as the direction of the wind W from the rear of the horizontal case 1 (horizontal direction). It's summery. As a result, the horizontal wind W from the rear of the main body case 1 flows along the upper surface of the wind direction adjustment plate 2, gradually changes its direction upward according to the curved portion, and is blown out from the front end of the main body case 1.

Next, when the operating lever 6 is operated downward in the opposite direction, the shaft 7 of the operating lever 6 moves upward about the fulcrum 8, and the connecting rod 4 connected thereto also moves upward. Then, since the wind direction adjusting plate 2 is connected to the connecting rod 4 at the shaft portion 5 as described above, it curves upward. At this time, since the wind direction adjusting plate 2 is made of a soft material S, it can be easily bent upward, and since the shaft parts 3 and 5 are made of a rigid body G, it can be easily bent in the left and right direction. It has such rigidity that the entire wind direction adjustment plate 2 is difficult to twist. In addition, the end of the wind direction adjustment plate 2 on the side of the shaft 5 is arranged in the direction of the wind W from the rear of the main body case 1 (horizontal direction) as described above.
and are in the same direction. So, main case 1
The horizontal wind W from the rear flows along the lower surface of the wind direction adjustment plate 2, gradually changes its direction downward according to the curved part, and is blown out from the front end of the main body case 1.

As described above, in the air conditioning grill of this embodiment, the force is transmitted almost evenly to the entire wind direction adjustment plate 2 by operating the operation lever 6, so that the wind direction adjustment plate 2 can be adjusted to a predetermined position without being twisted. Easily curve in any direction. Therefore, the wind W from the rear of the main body case 1 flows smoothly along the wind direction adjustment plate 2, so that no noise is generated and the wind direction does not deteriorate.

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

(1) The rigid body G on the wind direction adjustment plate 2 may be arranged as follows in addition to the above embodiment.

As shown in FIG. 5, the vicinity of both shaft parts 3 and 5 of the wind direction adjustment plate 2 is formed into a wave shape, the rigid body G part is made of a soft resin such as soft vinyl chloride resin, and the other soft material S part is made of a soft material. A soft resin such as vinyl chloride resin obtained by two-color molding, or the above-mentioned rigid body G part is made of hard rubber with a Shore A hardness of about 80, and the other soft material S part is a low hardness rubber with a Shore A hardness of about 30. A sponge rubber obtained by two-color molding may also be used.

In addition, as shown in Fig. 6, the soft material S portion is molded in advance with soft resin, and this
It can also be formed so as to be wrapped around the shaft parts 3 and 5 formed by.

(2) In the above embodiment, the wind direction adjustment plate 2 is arranged horizontally to adjust the wind direction in the vertical direction, but the wind direction adjustment plate 2 is arranged vertically,
It can also be configured to adjust the wind direction in the left and right directions. Further, these two types of wind direction adjusting plates 2 can be installed together in one main body case 1. That is, the wind direction adjustment plate 2 can be arranged horizontally in the front part and vertically in the rear part of the main body case 1, or conversely, it can be arranged vertically in the front part and horizontally in the rear part. It can also be placed in

(3) In the above embodiments, the air conditioning grill of the present invention was embodied in an automobile instrument panel, but it can also be embodied in a household heater, an air conditioner, etc.

Effects of the invention In the air conditioning grill of the invention, the force applied to the wind direction adjustment plate is transmitted almost evenly to the entire wind direction adjustment plate.
Since the wind direction adjustment plate does not twist and the wind from the rear of the main body case flows smoothly along the wind direction adjustment plate, excellent effects are achieved in that less noise is generated and the wind direction is less likely to deteriorate.
