Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for an air conditioning grill, which is applied to an air conditioner mounted on a vehicle such as an automobile.

[0002]

2. Description of the Related Art Vehicles such as automobiles are provided with an air conditioner for adjusting the temperature and humidity of the air in the passenger compartment to make the passenger compartment comfortable. The conditioned air after being adjusted by the air conditioner is blown out from the air outlet provided in the vehicle compartment. A fin for changing the blowing direction of the conditioned air is provided at the air outlet, and the operator can freely change the blowing direction of the conditioned air by changing the direction of the fin.

The types of ventilation grills provided with fins that change the direction in which the conditioned air is blown will be described below. What is shown in FIGS. 8 and 9 is a round ventilation grill. In this ventilation grill 1, a round grill body 5 formed by fins 3 and a casing 4 is rotatably arranged inside a frame body 2, and an operator moves the grill body 5 in a three-dimensional direction. By rotating (up, down, left and right), the blowing direction of the conditioned air passing through the hole 5a can be changed.

Shown in FIGS. 10 and 11 is a rectangular ventilation grill with variable fins. The ventilation grill 6 is provided with a vertically adjustable fin 10 connected to a frame body 7 of an air outlet by a link 9 and a horizontal adjustment fin 12 similarly connected by a link 11 so as to be rotatable. The operator changes the direction of the fins 10 and 12 so that the direction in which air is blown out can be changed.

What is shown in FIGS. 12 to 14 is a casing.
It is a square ventilation grille 15 (see FIG. 14) that has fins 14 integrated with 13. That is, this rectangular ventilation grill 15 has a casing 13 with a rotating shaft 16.
A grill body 19 having a fin 14 integrated with a casing 13 and a left and right adjusting fin 18 connected by a link 17 is rotatably mounted inside a frame body 20 (see FIG. 14). The operator can freely change the blowing direction of the conditioned air by rotating the grill body 19 and the left and right adjusting fins 18.

The state of rotation of the grill body 19 will be specifically described with reference to FIG. For example, if the operator turns the grill main body 19 about the rotary shaft 16 in the direction of the arrow A to turn it, that is, the grill main body 19 in the upright state (two-dot chain line). Rotate the upper side of the grille 19 so that it is inside the front wall 20a of the frame 20 and the lower side so that it protrudes outwardly from the front wall 20a of the frame 20. ), The upper side of the grill body 19 rotates into the inside of the frame body 20 by rotating a distance B from the front wall 20a of the frame body 20, and the lower side of the grill body 19 forms a distance C from the front wall 20a of the frame body 20. It rotates to project to the outside of the frame body 20. When the grill body 19 is tilted in this manner, the conditioned air is blown upward from the grill body 19. At that time, the left and right adjustment fins
By rotating the 18, it is possible to further blow out the conditioned air in a desired direction on the left and right.

[0007] As a ventilator grill,
Some are disclosed in Japanese Patent Publication No. 60-157420. What is disclosed in this publication is a louver support frame rotatably provided inside a casing, and a louver projecting from the support frame. As a ventilator structure, there is one disclosed in Japanese Utility Model Laid-Open No. 61-80111. The one disclosed in this publication is provided with a baffle plate which closes the ventilation passage near the upstream side of the ventilation register.

[0008]

In the prior art described above, especially the casing 13 shown in FIGS. 12 to 14 is used.
In the rectangular ventilation grill 15 in which the grill body 19 having the fins 14 integrated with is mounted in the frame body 20, the operator rotates the grill body 19 by the rotating shaft 16 to change the blowing direction of the conditioned air. In this case, for example, the upper side of the grill body 19 is rotated inside the frame body 20, and the lower side is rotated to the frame body.
When it is rotated so as to project from the front wall 20a of 20, the part of the opening of the air blow-out on the upper side is hidden inside the frame body 20 as shown in FIG. 14 and FIG. There is a problem that the effective opening area of the air outlet is reduced, the blowing performance is deteriorated, and the appearance is deteriorated. Further, a part of the lower side also protrudes from the front wall 20a of the frame body 20 to the outside, and there is a problem that the appearance is deteriorated similarly to the above (see also FIG. 15).

In the ventilator grill disclosed in Japanese Utility Model Laid-Open No. 60-157420, the louver support frame is supported by a rotation shaft, and when the louver support frame is rotated, the louver support frame is rotated about this shaft. Since the louver support frame moves, a part of the louver support frame may be hidden by the casing. Therefore, it does not solve the problem of the present invention. Further, in the structure of the ventilator disclosed in Japanese Utility Model Laid-Open No. 61-80111, when the air outlet of the ventilation register is directed upward, there is a risk that the ventilation performance may deteriorate due to the orientation of the ventilation register and the baffle plate. It does not solve the problem of the invention.

The present invention has been made to solve the above-mentioned problems, and when a grill body having fins is rotatably supported by a plurality of links, the grill body is rotated when the grill body is rotated. It is an object of the present invention to provide a support device for an air-conditioning grill in which a part of the air conditioner is not hidden, and thereby a reduction in air blowing performance and an unattractive appearance are avoided.

[0011]

As a means for solving the above-mentioned problems, the present invention rotatably supports a grill main body having fins inside a frame by a plurality of links, and the plurality of links are provided. The pitch of the rotation fulcrums on the side of the grill body is narrower than the pitch of the rotation fulcrums on the other side when the grill body is upright.

[0012]

As described above, according to the present invention, the pitch of the pivotal fulcrum of the plurality of links rotatably supporting the grille main body on the grille main body side in the upright state of the grille corresponds to the pivotal fulcrum on the other side. Since it is narrower than the pitch, when the grill body is rotated and its direction is changed, the rotation angles of the multiple links change, and the grill body rotates in a state close to ideal,
Part of the grill body is not hidden.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
The same members as those in FIGS. 12 to 14 will be described with the same reference numerals. In the figure, reference numeral 15 is a ventilation grill according to the present invention. Inside the frame 20 of the ventilation grille 15, as shown in FIG. 2, a fin 13 integrated with the casing 13 and a left / right adjusting fin 18 (see FIGS. 5 and 13) connected by a link are attached to the casing 13. A grill main body 19 is provided.

The grill body 19 is rotatably supported inside the frame 20 by two links. That is, one end is rotatably attached to the grill body 19, and the other end is rotatably supported by the first link 21 and the second link 22 rotatably attached to the frame body 20.

The first link 21 and the second link 22 of the rotation fulcrum 23 on the grill main body 19 side when the grill main body 19 is in the upright state (the state not shown in FIG. 1 which is not rotated). The mounting pitch D is narrower than the mounting pitch E of the rotation fulcrum 24 on the other mounting side of the first link 21 and the second link 22.

The attachment of the first link 21 and the second link 22 is performed as follows. That is, as shown in FIG. 2, since the fitting holes 25 are provided on the grill body 19 side of the first link 21 and the second link 22 and the projecting portions 26 are provided on the other side, the fitting holes 25 are formed in the casing. Protrusion 27 provided on 13
Then, the grill body 19 is rotatably supported inside the frame body 20 by fitting the protrusion 26 into the hole 28 provided in the frame body 20.

The first links 21 and the second links
An arm 29 (see FIG. 2) connecting the two 22 is for keeping the grill main body 19 parallel when the grill main body 19 is supported by these two links 21, 22. This arm 29
With this, it is possible to suppress the play of the two links 21 and 22 and the grill body 19.

Next, the principle of mounting the first link 21 and the second link 22 will be described with reference to FIG. As shown by the arrow F in FIG. 3, the first link 21 is the first link 21 in the ascending direction.
The front-back movement amount G of the rotation fulcrum 23 of 21 is small, and the front-back movement amount H is large in the downward direction.

As shown by an arrow I, the second link 22 has a large forward / backward movement amount J of the rotation fulcrum 23 of the second link 22 and a downward movement of the rotation fulcrum 23 of the second link 22. The amount of forward / backward movement K becomes smaller. In this way, the grill main body 19 is inclined by the difference in the moving positions of the first link 21 and the second link 22, for example, the rearward movement amount of the first link 21 is increased with the distance H, By reducing the amount of forward movement of the second link 22 to the distance K, the amount of forward protrusion of the grill body 19 can be reduced.

The rotation fulcrums 23 and 24 move up and down while changing the angles of the two links 21 and 22, but as shown in FIG.
By adjusting the distance to the front of the 19, it is possible to adjust the height of the front. That is, when the distance from the rotation fulcrum 23 to the front surface of the grill body 19 is the dimension L, it can be made smaller by the distance N than when it is the dimension M.

Next, the operation of this embodiment will be described. As described above, the grill body 19 is rotatably attached first.
Since the mounting pitch D of the rotation fulcrum 23 on the grill body 19 side of the link 21 and the second link 22 in the upright state of the grill body 19 is narrower than the mounting pitch E of the rotation fulcrum 24 on the other side, the grill body When turning 19 to change its direction, the turning angles of the first link 21 and the second link 22 can be changed freely, so that the grill body 19 turns in a state close to ideal. This prevents a part of the grill body from being hidden by the frame body 20.

That is, as shown in FIG. 1, the grill main body
The upper side of 19 is rotated by a distance O from the front wall 20a of the frame body 20 and only enters the inside of the frame body 20, which is smaller than the conventional rotation distance B. In addition, the lower side of the grill main body 19 is conventionally a frame body 20.
Although it protruded from the front wall 20a of the vehicle by a distance C, such protrusion disappears when the links 21 and 22 are rotated (see also FIG. 5). Further, by changing the lengths of the links 21 and 22 in addition to the angles of the two links 21 and 22, it is possible to ideally rotate the grill main body 19 without hiding a part thereof. ..

An appropriate flick is required to hold the position of the grill body 19 at the pivot point. This flick is not necessary for all movable fulcrums,
If at least one point has the function, it is possible to achieve the goal of maintaining the position of the grill body 19.

In the present embodiment, the first link 21
The first link 21 and the second link 22, and the casing 13 are connected to each other and the second links 22 by the arms 29.
And the grill body 19 is kept parallel to each other by playing back and play with the two links 21 and 22 and the casing 13 in a direction as shown by an arrow P in FIG. Since the grill main body 19 can be kept parallel to each other, the links 30 and 31 can be downsized as shown in FIG.

[0025]

As described above, according to the present invention, the pitch of the pivotal fulcrum of the plurality of links for rotatably mounting the grill body on the grill body side in the upright state of the grill is pivoted to the other side. Since the pitch is narrower than the fulcrum pitch, when the grill body is rotated to change its direction, the rotation angles of the plurality of links are changed, and a part of the grill body is not hidden by the frame.

That is, the upper side of the grill main body does not go deep into the frame body, and the effective opening area can be maximized, so that the blowing performance can be improved.
Furthermore, since the lower part does not have a protrusion, the grill body is in a natural position when viewed from the front, and the appearance is good.
