DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower register for changing the direction of wind blown into a passenger compartment of a vehicle or the like. In particular, the present invention relates to a blower register that changes a direction of wind blown along a blown path by rotating a barrel disposed in the blower path.

[0002]

2. Description of the Related Art In a vehicle, for example, an automobile, the above-mentioned airflow register is provided on an instrument panel or the like, and the air blown out from an airflow source is sent into the vehicle interior through the airflow register. In a normal blower register, the direction of the wind blown into the vehicle compartment can be changed to any desired direction by the vehicle occupant rotating the barrel which is a constituent member thereof.

As such a blower register, for example, the one shown in FIG. 19 is known. The blower register 51 is attached to an instrument panel 52 of an automobile, and includes a bezel 53 forming a blower passage and a barrel 55 rotatably supported by the bezel 53 via a pin 54. And The wind sent from an air supply source (not shown) is guided by a bezel 53, travels as indicated by an arrow A, and is sent out through a barrel 55 to a vehicle room extending to the right of the instrument panel 52. By rotating the barrel 55 about the pin 54, the barrel 55 can take three positions: a neutral position indicated by a solid line, an upward position indicated by a chain line, and a downward position indicated by a broken line. By turning the barrel 55 by a passenger (not shown), the wind direction can be changed to a desired direction.

[0004]

As shown in FIG. 19, a conventional blower register has a barrel 55 having a single pin 54.
Was just supported. That is, the barrel 55 has only one rotation center. As a result, when the barrel 55 is rotated in one direction, for example, in the direction of the downward position (broken line),
The lower part of the barrel 55 is at the bottom of the bezel 53 (left side in the figure).
Was greatly penetrated. In this state, bezel 5
The leading end 53a of the third end is largely exposed to the front of the barrel 55 (the right side in the figure), so that the wind progressing out of the barrel 55 at the downward position (broken line) and going downward in the figure is the bezel end shelf. There was a problem that it was inhibited by the part 53a.

In order to prevent the rotating barrel 55 from hitting the bottom inner wall of the bezel 53, the length of the barrel 55 cannot be too long. As a result, when the barrel 55 is at the neutral position (solid line), a large space B is formed between the lower end of the barrel 55 and the bezel tip shelf 53a, and therefore the bezel tip shelf 53a is largely exposed to the outside and boarded. There is also a problem that the external appearance is visually impaired and the appearance is significantly impaired.

As a register which can solve the above-mentioned problem caused by exposing the bezel tip shelf 53a to the outside, there is a so-called fin type register which is not a barrel type as shown in FIG. However, this fin type register has a problem that the cost is very high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in conventional registers, and uses a low-cost barrel type register. It is an object of the present invention to provide a blower register that does not hinder the progress of the wind even when is rotated.

[0008]

In order to achieve the above-mentioned object, a blower register according to the present invention has at least two barrel rotation centers arranged side by side in a blower direction, and the barrel has a barrel rotation center. The center of rotation of the barrel changes between the at least two barrel rotation centers when rotating from the neutral position to one side and when rotating to the other side.

[0009]

The barrel rotates from the neutral position in one direction and in the other direction opposite thereto. The center of rotation when the barrel rotates in one direction (for example, upward) is, for example, the center of rotation on the upstream side in the blowing direction. When the barrel rotates in the other direction (for example, downward), the center of rotation of the barrel changes to, for example, the center of rotation on the downstream side. This change in the center of rotation makes it possible to cause the barrel to perform not only a single point-centered rotational movement but also a movement in a direction perpendicular to the blowing direction.
As a result, it is possible to prevent the bezel surrounding the barrel, particularly the bezel tip shelf, from hindering the progress of the wind blown from the barrel. Further, compared to a case where the barrel is simply rotated about one point, even if the length of the barrel is increased, the barrel does not hit the inner wall of the bezel when the barrel is rotated. If the length of the barrel can be increased, when the barrel is located in the neutral position, the bezel tip shelf will not be concealed by the barrel and will not be significantly exposed to the outside, and therefore, the instrument panel to which the barrel is attached, Good appearance can be maintained.

[0010]

1 shows a first embodiment of a blower register according to the present invention.
An example is shown. Referring to FIG.
Is mounted on the instrument panel 2 and the barrel 5 is supported by the bezel 3 and disposed inside the same as in the conventional device shown in FIG. However, in this embodiment, as shown in FIG. 2, a shaft member 6 that is bent in a crank shape is fixed to the side surface 5a of the barrel 5. Although only the front side surface 5a is shown in the drawing, a similar shaft member is actually fixed to a not-shown rear side surface.

A portion 6a of the shaft member 6, which is fixed to the side surface 5a, forms a first support shaft, and a tip portion 6b forms a second support shaft. As shown in FIG. 3, the first support shaft 6a is provided on the first side plate 3b of the bezel 3, and the second support shaft 6b
Is fitted in an arc-shaped guide hole 7 having a center at the center.
On the other hand, the second support shaft 6b is fitted in another arc-shaped guide hole 8 provided on the second side plate 3c of the bezel 3 and centered on the first support shaft 6a. As shown in FIG. 1, the guide holes 7 and 8 respectively include a second support shaft 6b and a first support shaft 6a.
Are formed in an arc shape centered at the center, so that both are arranged such that the interval between the lower portions is wide and the interval becomes narrower as going upward.

The configuration of the register 1 according to this embodiment is roughly as described above. Hereinafter, the mode of operation will be described.
The state shown in FIG. 1 is a case where the barrel 5 is at the neutral position. In this state, the first support shaft 6 a is in contact with the lower end of the left guide hole 7, while the second support shaft 6 b is in contact with the lower end of the right guide hole 8. Barrel 5 from this state
Is turned downward, the second support shaft 6b cannot move downward. Therefore, the barrel 5 rotates counterclockwise around the second support shaft 6b with the first support shaft 6a. Support shaft 6
a moves upward in the left guide hole 7. First support shaft 6a
Stops at a position where the first support shaft 6a contacts the upper end of the left guide hole 7, as shown in FIG. This position is the downward position of the barrel 5. In this state, the wind is directed downward by the barrel 5.

Next, when the barrel 5 is to be turned upward from the downward state, the distance between the guide holes 7 and 8
Since the distance between the first support shaft 6a and the second support shaft 6b is maximum in the neutral state shown in FIG. 1, the second support shaft 6b is only the center of rotation in the state of FIG. It rotates counterclockwise with the support shaft 6a and returns to the neutral position in FIG. When the barrel 5 is further turned upward, the first support shaft 6a
Stops at the lower end of the guide hole 7, the barrel 5 rotates counterclockwise around the first support shaft 6a with the second support shaft 6b, and at this time, the second support shaft 6b is Move upwards within. Then, as shown in FIG. 5, the second support shaft 6b
Is in contact with the upper end of the right guide hole 8, that is, in the upward state. In this state, the wind is directed upward.

When the barrel 5 is turned downward from the upward state in FIG. 5, the first support shaft 6 is moved in the same manner as when the barrel 5 is turned upward.
Since a is only the center of rotation, the barrel 5 rotates counterclockwise about the first support shaft 6a with the second support shaft 6b, and returns to the neutral position in FIG.

As is apparent from the above description, the movement of the two support shafts 6a and 6b is regulated as follows. That is, when moving the barrel 5 upward or downward,
The operation of each of the support shafts 6a and 6b is regulated such that one of the support shafts is fixed as a rotation center.

In this embodiment, when the barrel 5 is rotated in one direction, for example, in a counterclockwise direction toward the downward position (FIG. 4), the barrel is rotated about the first support shaft 6b. It rotates with the shaft 6a. As a result, the barrel 5 protrudes further forward (to the right) while lifting upward, which is a direction perpendicular to the blowing direction A. Therefore, barrel 5
As compared with a case where the wind simply rotates about the first support shaft 6a, the amount of the wind going downward from the barrel 5 whose flow is hindered by the tip shelf 3a of the bezel 3 is reduced, and A large amount of wind can be sent into the vehicle interior.

The fact that the barrel 5 is lifted up about the second support shaft 6b means that the length of the barrel lower portion when the barrel 5 is at the neutral position (FIG. 1) is increased as L. This also means that the lower end does not hit the bottom inner wall of the bezel 3 when the barrel 5 is turned to the downward position (FIG. 4). According to the conventional device having the first support shaft 6a as the center of rotation, the lower length of the barrel 5 must be shortened like R in order to avoid collision between the barrel 5 and the bezel 3. The degree of exposure of the bezel tip shelf 3a below the barrel 5 was B
I had to grow as big as Normally, since the position of the passenger's eyes is at the upper right of FIG. 1, if the bezel tip shelf 3a is largely exposed as described above, it is easy for the passenger to see it, and the appearance is significantly impaired. Was. On the other hand, according to the present embodiment, the length of the barrel lower portion can be increased as indicated by L, so that the degree of exposure of the bezel tip shelf 3a when the barrel 5 is at the neutral position is indicated by D. And the appearance is not impaired.

FIG. 6 shows a second embodiment of the present invention.
This embodiment is different from the first embodiment described above in that a first support shaft 16a and a second support shaft 16 formed on a shaft member 16 are provided.
b are both fixed to the barrel 5. As shown in FIG. 7, these support shafts 16a and 16b are fitted in guide holes 7 and 8 provided in one side plate 3b constituting the bezel 3. These guide holes 7,
8 is the same as that shown in FIG. The operation mode of the second embodiment is the same as that of the first embodiment shown in FIG. 1, and a description thereof will be omitted.

The structure of the two spindles fixed to the barrel 5 is not limited to the above two embodiments.
In short, when the barrel 5 is rotated upward or downward, the operation of each of the support shafts 6a and 6b is regulated so that one of the two support shafts is fixed as a rotation center. Just do it.

FIG. 8 shows a third embodiment of the present invention. In the register 11 according to this embodiment, the first support shaft 26a is fixed to the barrel 5, as shown in FIG. On the other hand, the second support shaft 26b is provided at the tip of the bracket 12 which is rotatably fitted on the first support shaft 26a. First
As shown in FIG. 10, the support shaft 26a is fitted into an arc-shaped guide hole 17 provided on the first side plate 3b of the bezel 3 and centered on the second support shaft 26b. The second support shaft 26b is fitted into a hole 18 provided in the second side plate 3c of the bezel 3. The hole 18 is merely a round hole, so that the second support shaft 26b is rotatable but does not move vertically or horizontally.

A first support shaft 2 is provided on the first side plate 3b of the bezel.
A first guide 14 for guiding the protrusion 13 formed on 6a is provided, and a second guide 15 arranged opposite to the first guide 14 is provided. First guide 14
Has a shape in which two portions curved in an arc shape are joined as shown in FIG. Also, the second guide member 1
5 acts so as to restrict the rotation of the first support shaft 26a when the projection 13 hits.

In this embodiment, the first support shaft 26a is located at the lower end of the guide hole 17 by pressing the upper end of the barrel 5 with a finger in order to turn the barrel 5 upward. Therefore, the barrel 5 rotates around the first support shaft 26a, and is in an upward state shown in FIG. At this time, the first support shaft 26a rotates independently of the bracket 12, and the second support shaft 26b does not rotate. At this time, the protrusion 13 on the first support shaft 26 a rotates while its tip is guided by the lower surface of the first guide 14.

When the lower end of the barrel 5 is pressed with a finger to lower the barrel 5 from the state shown in FIG. 12, the tip of the projection 13 comes into contact with the lower surface of the first guide 14 so that the barrel 5 is rotated by the first support shaft. Rotating clockwise around center 26a, FIG.
Return to the neutral position shown in. Thereafter, when the barrel 5 is further rotated downward, the tip of the projection 13 is disengaged from the left curved portion of the first guide 14. And furthermore, the projection 13 is the second
The guide 15 cannot rotate around the first support shaft 26a, so that the barrel 5 rotates clockwise about the second support shaft 26b. At this time,
The protrusion 13 rotates along the right curved portion of the first guide 14 and the second guide 15, and the first support shaft 26 a moves upward in the guide hole 17. In this case, the barrel 5 moves so as to protrude forward (to the right in the drawing) while lifting upward in a direction perpendicular to the blowing direction A.

As described above, also in the third embodiment, similarly to the first and second embodiments, the case where the barrel 5 rotates upward (counterclockwise) and the case where the barrel 5 rotates downward ( The center of rotation changes between the first support shaft 26a and the second support shaft 26b.

FIG. 13 shows a fourth embodiment of the present invention. In this embodiment, instead of using two cylindrical support shafts as in the above-described embodiments, a specially shaped shaft member 36 that curves upward as shown in FIG. 14 is used. I have. The shaft member 36 has a left hanging portion 36a, a right hanging portion 36b, and a curved concave portion 40 formed between the both hanging portions.

On the other hand, holes provided in the side plate of the bezel 3 for supporting the curved shaft member 36 are indicated by reference numerals 27 in FIG.
As shown in the figure, the shaft member 36 is formed in a curved shape corresponding to the curved shape. More specifically, the bearing hole 27
Is formed in a shape in which a left bearing hole 27a for accommodating the left hanging portion 36a of the shaft member 36 and a right bearing hole 27b for accommodating the right hanging portion 36b of the shaft member 36 are curved. The shaft member 3 is located between the holes 27a and 27b.
An overhang portion 27c for supporting the sixth curved concave portion 40 is formed. The upper end of the overhang portion 27c is formed in a smooth curved shape, for example, in an arc shape. Further, as shown in FIG. 13, the curved concave portion 40 is supported by the overhang portion 27c, and the lower end of the right hanging portion 36b of the shaft member 36 is in contact with the lower end of the right bearing hole 27a. A space G having an appropriate width is formed between the upper surface and the upper surface of the bearing hole 27.

In FIG. 13, the projecting portion 2 of the bearing hole 27 is shown.
The barrel 5 is held at the neutral position by receiving the curved concave portion 40 of the shaft member 36 by 7c. When the barrel 5 is turned upward, that is, counterclockwise from this neutral position, the shaft member 36 moves so as to wrap leftward along the upper end of the overhang portion 27c, whereby the barrel 5 moves around the overhang portion 27c. Rotates counterclockwise. Then, as shown in FIG.
The rotation of the barrel 5 stops in a state where the lower end of the barrel a contacts the lower end of the left bearing hole 27a. This state is the upward state of the barrel 5.

When the barrel 5 in the upward state is turned downward, that is, clockwise, the shaft member 36 is turned over.
7c so as to move to the right along FIG.
Return to neutral position. In this state, the right hanging portion 36b of the shaft member 36 contacts the lower end of the right bearing hole 27b, so that the shaft member 36 cannot move around along the overhang 27c thereafter. Therefore, when the barrel 5 is further rotated upward from the neutral position, the shaft member 36
Right hanging part 36b supported by right bearing hole 27b
Is rotated clockwise only within the range permitted by the space G. At this time, the barrel 5 moves so as to protrude forward (to the right in the figure) while lifting upward. This movement of the barrel 5 stops when the upper surface of the shaft member 36 contacts the upper surface of the bearing hole 27, as shown in FIG. This state is the downward state of the barrel 5.

In the fourth embodiment, similarly to the above-described embodiments, the barrel 5 rotates upward (counterclockwise) and downward (clockwise). In some cases, the center of rotation changes. In the case of upward rotation, the center X of the projecting portion 27c of the bearing hole 27 becomes the center of rotation, and in the case of downward rotation, the center Y of the right-side hanging portion 36b of the shaft member 36.
Is the center of rotation.

Although the present invention has been described with reference to several embodiments, the present invention is not limited to these embodiments and can be variously modified. For example, in the description so far, the barrel 5 rotates vertically about the horizontal axis H as shown in FIG. 17, but the barrel 5 is rotated about the vertical axis V as shown in FIG. The present invention can also be applied to the case where the rotation is performed in the left-right direction. Further, in each of the above embodiments, the case where the rotation center of the barrel 5 changes between the two rotation centers has been described as an example, but the rotation center may change between three or more rotation centers. There is no problem.

[0031]

According to the present invention, the center of rotation changes between when the barrel rotates in one direction (for example, upward) and when the barrel rotates in the other direction (for example, downward). I do. Due to this change in the center of rotation, the entire barrel can be shifted in a direction perpendicular to the blowing direction. In this case, if the direction in which the entire barrel is displaced is a direction away from the tip shelf of the bezel, the amount of wind blown out of the barrel that is inhibited by the tip shelf of the bezel is reduced. As a result, more wind can be sent to the vehicle interior through the barrel without waste.

Further, when the barrel is rotated from the neutral position to one side (for example, downward), the entire barrel can be shifted in a direction perpendicular to the blowing direction. Even if the length is increased, the barrel can be prevented from hitting the inner wall of the bezel. If the length of the barrel can be increased in this manner, when the barrel is in the neutral position, more of the tip shelf of the bezel can be hidden by the barrel so as not to be in the field of view of the vehicle. Thereby, the appearance of the instrument panel including the barrel and the bezel can be improved.
