[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outlet grill which is installed, for example, in the interior of a motor vehicle and adjusts the direction of airflow for air conditioning.

[0002]

2. Description of the Related Art Conventionally, as this kind of technique, for example, a technique disclosed in Japanese Patent Application Laid-Open No. Hei 3-271563 is known. As shown in FIGS. 8 and 9, in this conventional technique, the outlet grill 39 is provided at the front end of the air duct 40 and includes a main body case 41 having a substantially square tubular shape. In the main body case 41, a plurality of (four in the figure) wind direction deflecting plates 42 are provided in parallel. Each wind direction deflecting plate 42 includes a bendable plate-shaped portion 43 and a first shaft 44 projecting up and down at a front end thereof. By fitting the first shaft 44 into a shaft hole 45 formed in the main body case 41, the front end of the wind direction deflecting plate 42 is rotatably supported with respect to the main body case 41. The rear ends of the wind direction deflection plates 42 are connected to each other by rods 46.

In FIG. 9, parallel links 47 are provided above and below the wind direction deflecting plates 42 located at both left and right ends, ie, between the main body case 41 and the wind direction deflecting plates 42. At the front end and the rear end of the parallel link 47, insertion holes 48 and 49 are formed, respectively. A second shaft 50 projecting vertically from the rod 46 is inserted into the rear insertion hole 49. Further, the first shaft 44 of the wind direction deflecting plate 42 is inserted into the front insertion hole 48.

An operation lever 51 is provided on the main body case 41 so as to protrude slightly from the front end thereof, and is supported so as to be rotatable in the left-right direction. The operation lever 51 is provided in parallel with each of the parallel links 47, and the rear end thereof is
6. By rotating the operation lever 51 in the left-right direction, each parallel link 47 is rotated around the first shaft 44 in parallel with the operation lever 51. Along with this, the rod 46 is moved left and right forward, and the rear end of each wind direction deflecting plate 42 is moved left and right forward. Further, each wind direction deflecting plate 42 is rotated about the first shaft 44 while being curved at the plate-shaped portion 43. As a result, the wind W from the rear is deflected along the wind direction deflecting plate 42 through the air duct 40, and the main body case 4
The direction of the wind W blown from the front end of 1 is adjusted.

[0005]

However, in the above-mentioned prior art, the respective insertion holes 48, 49 of the parallel link 47 are not provided.
Were merely formed in a circular shape similar to each other. Therefore, when assembling the outlet grille 39, the operator may mistakenly recognize the front insertion hole 48 and the rear insertion hole 49, and may attach the parallel link 47 in the wrong direction. Was.

When foreign matter such as burrs remains in the shaft hole 45 for supporting the first shaft 44, the first
Frictional force is generated between the shaft 44 and the shaft hole 45. Therefore, the first shaft 44 may not be easily rotated due to the frictional force. When the rod 46 is moved right and left forward, that is, when the parallel link 47 is rotated about the first shaft 44, if the first shaft 44 is not rotated, the wind direction deflecting plate 42 is properly rotated. Not curved. as a result,
There was a risk that the direction of the blown wind W could not be properly adjusted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to prevent both ends of a link member from being erroneously assembled and to prevent the bending of a wind direction deflecting plate. It is an object of the present invention to provide an outlet grille capable of suppressing a decrease in a wind direction adjusting function.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a main body case which is disposed in a ventilation duct and allows passage of wind from rear to front, and provided inside the main body case. A circular shaft hole, a wind direction deflecting plate disposed in the main body case, and having a bendable plate-like portion; and a main body formed at a front end of the wind direction deflecting plate so as to project vertically. A first shaft fitted into a shaft hole of the case and rotatably supported, a connecting member for connecting rear ends of the wind direction deflecting plates to each other, and at least one rear end portion of the wind direction deflecting plate or a second axis the formed connected by members projecting in the vertical direction, is disposed between at least one of said wind deflecting plate and the body case, its
Outlet grille having a first insertion hole through which the first shaft is inserted in the wind direction deflection plate and a link member having a second insertion hole through which the second shaft is rotatably inserted. a is, to form a first insertion hole in the link member in a non-circular shape, is fitted to the insertion hole of the first shaft before <br/> Symbol to be inserted into the first insertion hole the portion of the cross-sectional shape and substantially the same shape as the insertion hole, the first insertion hole
, While the first shaft cannot be relatively rotated,
The gist is that the second insertion hole in the link member is formed in a circular shape.

[0009]

According to the above construction, the link member is rotated,
By moving the connecting member, each wind direction deflecting plate is rotated in the same direction with the first axis as a fulcrum with respect to the main body case, and the plate-like portion is curved. Therefore, the wind sent through the air duct flows along each wind direction deflecting plate, and the wind blown forward from the main body case is deflected according to the turning direction of each wind direction deflecting plate and the curved state of the plate-shaped portion. Is done.

Here, the first insertion hole of the link member and the first
Since the fitting portions of the first shaft and the first shaft are formed in a non-circular shape, the rotation torque can be transmitted between the first shaft and the first insertion hole. Therefore, when the link member is rotated, the first shaft is integrally rotated. Therefore, for example, even when a large frictional force is generated between the first shaft and the shaft hole of the main body case, and the first shaft is difficult to rotate, the first shaft is not rotated by the link member. Accordingly, it is forcibly rotated. Therefore, the smooth movement of the wind direction deflection plate is not hindered.

In the link member, since the first insertion hole and the second insertion hole are formed in different shapes, each of the insertion holes corresponding to the first axis and the second axis is formed. Identification becomes easy.

FIG. 2 is a perspective view of the outlet grill G in this embodiment, FIG. 3 is a plan sectional view of the outlet grill and the like, and FIG. 4 is a sectional view taken along line AA of FIG. FIG. 5 is a sectional view taken along line BB of FIG. In FIG. 3, an outlet grill G is provided at a front portion of the cylindrical blow duct 1. The outlet grille G includes a main body case 2 having a substantially rectangular cylindrical shape, and the main body case 2 is provided with a plurality of fixed plates 3 extending in the left-right direction. The main body case 2 is supported by a rotating shaft 4 projecting from both sides so as to be rotatable up and down with respect to the air duct 1.

Behind the fixed plate 3 in the main body case 2, a plurality of (four in this embodiment) wind direction deflecting plates 5A, 5B, 5C and 5D extending in the vertical direction are arranged in parallel at right and left sides at equal intervals. Are located. Each wind direction deflection plate 5A-5D
Has a plate-shaped portion 6 and first shafts 7A, 7B, 7C, 7D formed at the front end thereof so as to protrude vertically. The plate-like portion 6 includes a flexible portion 8 that can be bent and a hard portion 9 that is integrally formed at a rear portion thereof. The soft part 8 is made of rubber mixed with polypropylene, and the hard part 9 and the first shafts 7A to 7D are made of polypropylene mixed with glass fiber. Above and below the hard portion 9, a second shaft 10 having a tip-cracked shape and a slightly enlarged tip is formed so as to protrude in the vertical direction.

A first shaft 7A is provided on the upper and lower inner sides of the main body case 2.
7D are formed respectively.
The upper and lower ends of the first shafts 7A to 7D are fitted into the respective shaft holes 11. For this reason, the respective wind direction deflecting plates 5A to 5D are rotatably supported on the main body case 2 about the first shafts 7A to 7D. In addition, each of the wind direction deflection plates 5A to 5D
Is connected at its rear end, that is, at the hard portion 9, to left and right elongated rods 12 as connecting members.

Here, of the four wind direction deflecting plates 5A to 5D, the wind direction deflecting plates 5 located at the left and right ends of the main body case 2 are provided.
Above and below A, 5D, parallel links 13 as link members are arranged in parallel with the main body case 2. As shown in FIG. 5, a first insertion hole 14 is formed at the front end of each parallel link 13, and a second insertion hole 15 is formed at the rear end. The first shafts 7A and 7D are inserted through the first insertion holes 14. Second
The insertion hole 15 has an undercut shape, and the second shaft 10 is fitted into the second insertion hole 15.
The end face of the parallel link 13 and the tip face of the second shaft 10 are substantially flush, and the parallel link 13 is rotatable with respect to the second shaft 10.

As shown in FIGS. 2 and 3, in the main body case 2, an operation lever 16 is supported at a substantially center between the two fixed plates 3 in the middle stage so as to be rotatable about a shaft 2a. I have. The operating lever 16 is disposed in parallel with each parallel link 13, and has a rear end portion on which the shaft 1 of the rod 12 extends.
2a so as to be rotatable. The front end of the operation lever 16 projects slightly forward of the main body case 2. Further, the operating lever 16 is provided with an elastic force applying means such as a leaf spring 17. Then, a frictional force is applied between the operation lever 16 and the fixed plate 3 by the elastic force of the leaf spring 17, and the position of the operation lever 16 can be maintained.

The configuration as described above is basically the same as the configuration of the outlet grille in the prior art, and the features of this embodiment will be described in detail below. FIG. 1 is a perspective view showing the wind direction deflecting plates 5A and 5D and the parallel link 13. In FIG. 1, the first insertion hole 14 of the parallel link 13 has an oval shape, and the second insertion hole 15 has a circular shape. The upper and lower ends of the first shafts 7A and 7D of the wind direction deflecting plates 5A and 5D corresponding to the parallel link 13 have a two-stage structure with a neck 18 and a head 19. The neck 18 has the same oval shape as the first insertion hole 14, and its height is equal to the thickness of the parallel link 13. And the neck 18 of the first shaft 7A, 7D
Are fitted into the first insertion holes 14 of the parallel link 13. The head 19 has a cylindrical shape, and the main body case 2
Is fitted in the shaft hole 11. Therefore, the first shafts 7A and 7D cannot rotate relative to the parallel link 13 at the neck portion 18. In other words, the first shafts 7A and 7D are integrally rotated with the rotation of the parallel link 13. Therefore, the rotation of the head 19 in the shaft hole 11 is allowed.

As shown in FIG. 4, the tips of the first shafts 7B and 7C of the two central wind direction deflecting plates 5B and 5C have a conventional cylindrical shape, and are fitted into the shaft holes 11. And is rotatably supported by the main body case 2.

Next, each wind direction deflecting plate 5 for the rod 12
A connection state of A to 5D will be described. As shown in FIG. 6, the rod 12 has connecting portions 20A, 20B having a substantially U-shaped cross section connected to the hard portion 9 of each of the wind direction deflecting plates 5A to 5D.
20C and 20D are formed at equal intervals. As shown in FIGS. 4 and 5, the side surface of each of the connecting portions 20A to 20D has a parallelogram shape slightly inclined with respect to the front-back direction of the outlet grille G. On the other hand, as can be seen from FIG.
At the rear end of the hard portion 9 of each of the wind direction deflecting plates 5A to 5D, a cutout portion 21 which is slightly inclined is formed similarly to the side surface shape of the connecting portions 20A to 20D. A part of the hard part 9 adjacent to the notch 21 is a thin part 22 formed thinner than the other part. These notches 21 and thin portions 2
2 is substantially the same as the side surface shape of the connecting portions 20A to 20D. Then, the connecting portions 20A to 20D are fitted into the cutout portions 21 and the thin portions 22, so that the wind direction deflecting plates 5A to 5D are connected to the rod 12 in a pair.

Further, as shown in FIG.
On the inner surfaces of A to 20D, convex portions 23A, 23B, 23C,
23D are respectively formed. Here, the rod 12
In the connecting portions 20A, 20D located at the left and right ends of the, the convex portions 23A, 23D are formed on the inner surface on the left side (upper side in the figure), and in the central two connecting portions 20B, 20C, the convex portions 23B, 20C are formed. 23C is formed on the right inner surface. In addition, corresponding to each of these convex portions 23A to 23D,
The thin portion 22 of the hard portion 9 in each of the wind direction deflection plates 5A to 5D
Are formed with recesses 24A, 24B, 24C and 24D, respectively. Then, in a state where the respective wind direction deflection plates 5A to 5D and the rod 12 are connected, each of the recesses 24A to 24
D and the projections 23A to 23D are engaged with each other.

Next, the operation of the outlet grill G configured as described above will be described. Now, in the state of FIG. 3, when the operation lever 16 is rotated rightward, as shown in FIG. 7, each of the parallel links 13 rotates in parallel with the operation lever 16 around the first shafts 7A to 7D. Being moved,
The rod 12 is moved obliquely forward. For this reason, the front ends of the wind direction deflecting plates 5A to 5D are rotated about the first shafts 7A to 7D, and the rear ends thereof are moved obliquely forward, so that the respective wind direction deflecting plates 5A to 5D. Are curved in the same manner as each other. As a result, the wind W sent through the air duct 1 flows along each of the wind direction deflecting plates 5A to 5D, and the wind W blown out from between the fixed plates 3 of the main body case 2 moves rightward according to the curved state. Is deflected to

Here, for example, when foreign matters such as burrs remain in the shaft holes 11 corresponding to the wind direction deflecting plates 5A and 5D, the foreign matter such as burrs is located between the shaft holes 11 and the first shafts 7A and 7D. There is a possibility that a large frictional force is generated and the first shafts 7A and 7D are difficult to rotate. However, in this embodiment, the first insertion hole 14 of the parallel link 13 provided corresponding to the wind direction deflecting plates 5A, 5D and the neck 18 of the first shafts 7A, 7D have the same oval shape. Therefore, torque can be transmitted between the first insertion hole 14 and the first shafts 7A and 7D. For this reason, even if a slight frictional force is generated between the first shafts 7A, 7D and the shaft hole 11, when the parallel link 13 is rotated, the first shafts 7A, 7D are parallelized. The link 13 is forcibly rotated with the rotation of the link 13. Therefore, the smooth movement of the wind direction deflecting plates 5A, 5D is not hindered, and the wind direction deflecting plates 5A, 5D are not hindered.
D is curved into a suitable shape. As a result, at least the direction of the wind W blown out along the wind direction deflecting plates 5A and 5D can be appropriately adjusted, and thus the wind direction deflecting plates 5A and 5D can be adjusted.
It is possible to suppress a decrease in the wind direction adjusting function caused by the poor curvature of D.

Further, in this embodiment, since the first insertion hole 14 and the second insertion hole 15 of the parallel link 13 are formed in different shapes, an operator can attach the parallel link 13 to the first link. When assembling the shafts 7A, 7D and the second shaft 10, the first insertion hole 14 and the second insertion hole 15 are misidentified,
It is not necessary to assemble the parallel link 13 by mistake before and after. As a result, workability can be improved.

Further, in this embodiment, the side surface of each of the connecting portions 20A to 20D of the rod 12 has a slightly inclined parallelogram shape, and each of the wind direction deflecting plates 5A
Similarly, the notch 21 and the thin portion 22 of 5D have a parallelogram shape. For this reason, when assembling the rod 12 and the wind direction deflecting plates 5A to 5D, the vertical direction of the rod 12 can be easily identified. Therefore, even if the worker attempts to assemble the rod 12 as it is on the wind direction deflecting plates 5A to 5D by mistaken in the vertical direction of the rod 12,
The connection portions 20A to 20D and the notch portion 21 are inconsistent, and it becomes impossible to assemble the two members 12, 5A to 5D. Therefore, the rods 12 are moved with respect to the wind direction deflection plates 5A to 5D.
It is possible to reliably prevent the upper and lower parts from being erroneously assembled.

At the same time, when connecting each of the wind direction deflecting plates 5A to 5D and the rod 12, the convex portions 2 of the connecting portions 20A to 20D are connected.
The recesses 24A to 24D of the thin portion 22 are engaged with the recesses 3A to 23D. Therefore, each wind direction deflection plate 5A ~
Positioning of each of the connecting portions 20A to 20D with respect to the 5D can be reliably performed, and the rod 12 and each of the wind direction deflecting plates 5A to 5D can be positioned.
D can be firmly connected.

In addition, the wind direction deflecting plates 5A and 5D to be disposed at the left and right ends are the first shafts 7 of the wind direction deflecting plates 5A and 5D.
A and 7D are slightly different in shape from the wind direction deflecting plates 5B and 5C to be disposed at the center in that a neck portion 18 is formed. Further, each of the wind direction deflection plates 5A to 5D is
Wind direction deflecting plates 5 to be placed on both left and right ends when assembling
There is a possibility that the wind direction deflecting plates 5B and 5C to be disposed at the center may be erroneously assembled reversely. However, in this embodiment, among the connecting portions 20A to 20D of the rod 12, the connecting portions 20A and 20D located at the left and right ends and the connecting portions 20B and 20C at the center position of the convex portions 23A to 23D are mutually different. Is different. In addition, each wind direction deflection plate 5A ~
In the thin portion 22 of the hard portion 9 in 5D, concave portions 24A to 24D are formed so as to correspond to these convex portions 23A to 23D.
Are formed. For this reason, when the arrangement of each of the wind direction deflecting plates 5A to 5D is incorrect, the worker may use the convex portion 23A.
23D and the recesses 24A to 24D can be recognized as being incorrect due to the mismatch of the engagement.

The present invention is not limited to the above-described embodiment, and may be implemented as follows, with a part of the configuration being appropriately changed without departing from the spirit of the invention. (1) In the above embodiment, the operation lever 16 is provided in parallel with each parallel link 13 and the wind direction is adjusted by operating the operation lever 16, but the operation lever is omitted and the parallel link is The front end may be extended from the main body case 2 to serve also as an operation lever.

(2) In the above embodiment, the parallel link 13 is provided above and below the wind direction deflecting plates 5A and 5D located at both left and right ends. However, the parallel link is provided only above or below the wind direction deflecting plate. Only, or may be provided above and below the wind direction deflection plate located at the center. Further, the number of wind direction deflecting plates to be provided with the parallel link may be three or more.

(3) In the above embodiment, the second shaft 10 is formed so as to protrude above and below the hard portion 9. However, an extending portion or the like extending vertically is formed on the rod, and the second shaft 10 is extended. You may make it protrudely provide a 2nd shaft from a part up and down.

(4) In the above embodiment, the air outlet grille G is provided with the wind direction deflecting plates 5A to 5D for deflecting the wind direction in the left and right directions. However, a wind direction deflecting plate for deflecting the wind direction in the up and down direction is provided. It can also be embodied in an outlet grill.

[0032]

As described above in detail, according to the outlet grill of the present invention, it is possible to prevent both ends of the link member from being erroneously assembled, and to cause the bending of the wind direction deflecting plate. Thus, an excellent effect that the deterioration of the wind direction adjusting function can be suppressed can be achieved.
