Description

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

[Prior Art] A conventional air conditioning grille has been proposed in which a number of air deflection plates made of thin plates of rubber or soft resin and shafts of metal or hard resin are supported by parallel links, and the parallel links are rotatably supported on a main body member, and the air direction is changed by operating the parallel links.

As a rotatable support structure between the parallel link and the main body member, as shown in FIG.
An anchor-shaped locking protrusion 22 is provided protrudingly on the
The parallel link 23 has a structure in which a locking hole 24 is provided and the locking protrusion 22 is inserted into the locking hole 24.

Conversely, as shown in FIG. 7, the parallel link 2
There is also a structure in which an anchor-shaped locking protrusion 22 is provided protruding from the third side, and a locking hole 24 into which the locking protrusion 22 is inserted is provided in the main body member 21.

[Problems to be Solved by the Invention] However, in order to prevent the parallel link 23 from falling off the main body member 21, the conventional air conditioning grill described above requires the locking protrusion 22 to be shaped like an anchor, or the locking hole 24 to be formed in the shape of an anchor. It was necessary to create a shape that corresponds to this. Therefore, the structures of the main body member 21 and the parallel links 23 become complicated, and there are problems in that the wind direction deflection plate and the parallel links 23 must be separately assembled to the main body member 21.

SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide an air conditioning grille which has a simple structure for the parallel link and main body member and which allows for easy assembly of the air deflector and the parallel link to the main body member.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a plurality of wind deflection plates each consisting of a plate-like part made of a soft material and a shaft made of a hard material, in the main body member. , a front end of each wind deflection plate is rotatably supported on the main body member by the shaft;
In addition to connecting the rear ends with a connecting member, an insertion hole is provided at the front end of the parallel link arranged between the main body member and the wind deflection plate, and the shaft of the wind deflection plate is inserted into the insertion hole to connect the parallel link at the front end. The link is sandwiched and supported and rotatably supported on the main body member, and the rear end of the parallel link is rotatably supported on the connecting member, and the parallel link is rotated about the axis of the front end of the wind deflection plate. A method is adopted in which a plurality of wind deflecting plates are deflected together by moving the wind deflecting plates.

[Function] By adopting the above means, the parallel link is securely supported between the two members, the wind deflection plate and the main body member, and the axis of the wind deflection plate is inserted into the insertion hole at the front end of the parallel link. The parallel link is rotatably supported with respect to the main body member, and the wind direction deflection plate and the parallel link can be easily assembled integrally to the main body member.

[Example] Below are examples 1 to 4 that embody the present invention.
This will be explained based on the diagram.

As shown in FIG. 1, inside the air duct 1, a barrel 2 as a main body member is attached to a rotating shaft 2 shown in FIG.
It is rotatably supported by a. Same barrel 2
An engagement recess 3 is bored in the front portion (left side in FIG. 1) of the parallel link 4, and an engagement protrusion 5 of the parallel link 4 is rotatably fitted into the engagement recess 3.

As shown in FIG. 3, an insertion hole 6 is provided at the position of the engagement convex portion 5 of the parallel link 4.
A stainless steel shaft 7b is inserted through the front end of each wind deflection plate 7. The airflow direction deflection plate 7 is composed of a bendable plate-shaped portion 7a made of a soft material such as rubber, resin, or metal, and the shaft 7b.

As shown in FIG. 3, the support structure for the front end of the parallel link 4 and the wind deflection plate 7 for the barrel 2 is such that the engagement protrusion 5 of the parallel link 4 is engaged with the engagement recess 3 of the barrel 2. In addition, the shaft 7b, which is the center of rotation of the wind deflection plate 7, is inserted into the insertion hole 6 provided in the parallel link 4, and the parallel link 4 is inserted between the wind deflection plate 7 and the barrel 2. The parallel link 4 and the wind direction deflecting plate 7 are supported so as to be able to rotate independently with respect to the barrel 2.

As shown in FIG. 1, in front of the wind deflection plate 7, there are five non-curved wind direction adjustment plates 9 that support the shaft 7b exposed in the middle and extend in the horizontal direction perpendicular to the wind deflection plate 7. Fixed to barrel 2.
Furthermore, connecting plates 11 as three connecting members extending in the horizontal direction are disposed at the top, bottom, and center of the rear portion of the wind deflection plates 7, and connect the rear end portions of the four wind deflection plates 7 together. ing. Of this connecting plate 11, extending portions 12 as connecting members extending forward from the connecting plate 11 are formed at both left and right end portions of the upper and lower connecting plates 11. A rotation shaft 12a extending from the parallel link 4 is inserted into a hole in the parallel link 4 to be rotatably supported. When the extending portion 12 moves from side to side, the parallel link 4 rotates about the axis 7b of the wind direction deflecting plate 7. At this time, in order to curve the rear part of the wind deflection plate 7 in the same front-back direction as the direction of the wind W from the rear of the air duct 1, the distance between the axis 7b of the front end of the wind deflection plate 7 and the rear end is The ratio of the distance between the coaxial shaft 7b and the rotating shaft 12a in the parallel link 4 is set to 1:0.75.

On the rearward extension line of the wind direction deflection plate 7, extension plates 10 constituting a part of the connecting member are fitted and fixed together by a concave-convex relationship, and each extension plate 10
are integrated by the three upper and lower connecting plates 11. The wind W coming from behind the blower duct 1 is always in the same direction.

An operating lever 13 extending in the front-rear direction is disposed at the center of the barrel 2, and a long hole 14 is provided at the rear thereof, into which a pin 15 fixed to the connecting plate 11 is inserted. In addition, the same operation lever 1
An elongated hole 16 is also formed in the center of the wind direction adjustment plate 3, into which a pin 17 fixed to the rear end of the wind direction adjustment plate 9 located at the front is inserted. At the front end of the operating lever 13, an operating knob 13a which is long in the left and right direction is supported so as to sandwich the wind direction adjustment plate 9 located at the front part and to be slidable left and right.

The functions and effects of the air conditioning grill constructed in this way will be explained.

As shown in Figures 1 and 2, the operation knob 1
When 3a is at the center position in the vertical and horizontal directions, the wind W from the rear of the blower duct 1 passes through the extension plate 10, the wind deflection plate 7, and the wind direction adjustment plate 9, and is blown straight forward.

Next, when the operating knob 13a is slid to the right, as shown in FIG. It rotates while moving forward by the amount allowed by the operation knob 13a, and its rear end moves to the left, opposite to the operating knob 13a. Then, the rear end of the wind direction deflection plate 7 supported by the extension plate 10 which is integrated with the pin 15 inserted into the elongated hole 14 at the rear end of the operating lever 13 and the connecting plate 11 is It moves to the left while shortening the span with the shaft 7b while its movement locus is controlled by the parallel link 4. At this time, as mentioned above, the shaft 7b of the front end of the wind direction deflection plate 7
The ratio of the distance between the rear end and the distance between the coaxial 7b and the rotating shaft 12a in the parallel link 4 is 1:0.75.
Therefore, the rear part of the wind direction deflection plate 7 is substantially the same as the direction of the wind W from the rear of the ventilation duct 1. In this way, the wind deflection plate 7 is in a curved state bulging to the left, and the wind W from the rear of the air duct 1 flows smoothly to the right along the wind deflection plate 7 and is blown out from the front end. At this time, the upper and lower parallel links 4 are connected to the engagement recess 3 of the barrel 2 shown in FIG.
The parallel link 4 rotates counterclockwise in FIG. 4 around the engagement protrusion 5 inserted into the holder, but the parallel link 4 is securely supported by being sandwiched between the two members, the wind deflection plate 7 and the barrel 2. Because of this, there is no risk of it falling off.
Moreover, it rotates relative to barrel 2.

Note that when the operating knob 13a is moved upward, the barrel 2 becomes integrated with the wind direction deflection plate 7, the wind direction adjustment plate 9, the extension plate 10, etc., as shown by the two-dot chain line in FIG. Rotate counterclockwise. Therefore, the wind W from the rear of the air duct 1 is blown out downward along the wind direction adjustment plate 9 located at the front.

As described above, in the air conditioning grill of this embodiment, the parallel link 4 and the barrel 2 have a simple-shaped engagement protrusion 5 and an engagement recess 3 instead of the conventional anchor-shaped protrusion.
The parallel link 4 and the wind deflection plate 7 are connected to the barrel 2.
Since the barrel 2 and the parallel link 4 are assembled together, the structure of the barrel 2 and the parallel link 4 is simplified. In addition, since the shaft 7b of the wind deflection plate 7 is inserted into the insertion hole 6 of the parallel link 4, and the engaging protrusion 5 of the parallel link 4 is inserted into the engagement recess 3 of the barrel 2, the wind deflection plate 7 and the parallel link 4 can be assembled to the barrel 2 at the same time, reducing the number of assembly steps and improving the assembly work efficiency.

The present invention is not limited to the above-mentioned embodiments, and can be modified as desired without departing from the spirit of the invention. For example, it can be configured as follows.

(1) As shown in FIG. 5, the parallel link 4 is provided with an insertion hole 6a that is larger than that of the above embodiment, and the barrel 2 is provided with an engagement protrusion 18 that is inserted into the insertion hole 6a. The engagement protrusion 18 has an insertion hole 1 for inserting the shaft 7b of the wind direction deflection plate 7.
Drill 9. Then, by fitting the engagement protrusion 18 of the barrel 2 into the insertion hole 6a of the parallel link 4 and inserting the shaft 7b of the wind direction deflection plate 7 into the insertion hole 19 of the barrel 2, the parallel link 4 and the wind direction A deflection plate 7 is rotatably supported on the barrel 2.

(2) In the above embodiment, the parallel link 4 is provided with the insertion hole 6 through which the shaft 7b of the wind deflection plate 7 is inserted, but the hole may also be a hole with a bottom.
Any hole is sufficient as long as it can rotatably support the shaft 7b.

[Effects of the invention] The air conditioning grill of the invention has a simple structure for the parallel links and main body members, reduces the number of assembly steps when assembling the wind deflection plate and the parallel links to the main body member, and is easy to assemble. The effect is that the attachment workability is good.
