[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-direction adjusting device which constitutes an air-conditioning outlet mounted on an instrument panel of an automobile. The present invention relates to a wind direction adjusting device that can be changed and can surely perform the changing operation with a simple structure.

[0002]

2. Description of the Related Art Conventionally, a plurality of wind direction adjusting blades are provided in two or more groups inside an air-conditioning case body having a rectangular tubular shape which constitutes an air-conditioning outlet, and each group is operated by operating an operating member. A wind direction adjusting device has been proposed in which a plurality of blades are simultaneously rotated.

One of them is, for example, Shoukai 62-1766.
No. 54 discloses that the barrel is rotatably supported around a horizontal axis or a vertical axis in an air-conditioning case body having a rectangular tube shape that constitutes an air-conditioning outlet, and is provided inside the barrel. A plurality of fins are rotatably supported in the same direction as the rotation direction of the barrel, the fins are divided into two groups, and the fin groups are connected to each other with a connecting rod for each group. Disclosed is a vehicle compartment air-conditioning outlet device in which a fin group of a group and a fin group of the other group are connected to each other via links or gears so that the fin groups and the fin group of the other group simultaneously rotate in opposite directions. In addition, for example
In Japanese Patent No. 41938, two sets of upper and lower louvers having two horizontal blades which are vertically arranged side by side inside a rectangular air-conditioning case body are rotatably supported around a horizontal axis, and each louver is rotatably supported. A gear for changing the angle is attached to one end of
It has a gear drive that connects an interlocking gear that meshes with the gear and an interlocking rack, and pushes and pulls the gear drive with respect to the air conditioning case body to move the upper and lower louvers through the interlocking gear. There is disclosed an airflow direction adjusting device that rotates in the same direction or rotates the upper and lower louvers in opposite directions via the interlocking rack.

[0004]

However, in the wind direction adjusting device disclosed in Japanese Utility Model Laid-Open No. 62-176654, the connecting rod is provided in addition to the plurality of fins regardless of whether the gears are interlocked or not. Since an air-conditioning case body has a large number of parts and a large number of support holes for supporting the rotation shafts of the fins are formed in the air-conditioning case body, a loss of air volume is likely to occur.

Looking at the wind direction adjusting device disclosed in Japanese Utility Model Laid-Open No. 56-141938, the rotation operation of each louver by the interlocking rack is surely performed, but the rotation of each louver by the interlocking gear is performed. Does not always rotate as set, or there is a possibility that the rotation itself may become impossible.

The present invention has been made to solve the above problems. Specifically, the number of parts is reduced to simplify the assembling work, and at the same time, the air distribution for a plurality of groups of wind direction adjusting blades is provided. An object of the present invention is to provide an airflow direction adjusting device that can surely and smoothly perform the characteristic adjustment operation and further reduce the airflow loss.

[0007]

SUMMARY OF THE INVENTION The object is to provide a plurality of pedestals, each of which is a main component of the present invention, having a gear portion that meshes with each other and pivotally supported by an air conditioning case body.
And a plurality of sets of wind direction adjusting blade groups having a plurality of parallel wind direction adjusting blades that are integrally provided upright on the upper surface of each pedestal,
And a single operating member for changing the rotation angle of each wind direction adjusting blade group via the gear portion.

Generally, the free end side of the wind direction adjusting blades is open, but the free ends of the blades are connected and integrated with a reinforcing plate for each of a plurality of groups of wind direction adjusting blades. There is also. Further, preferably, a plate-like spacer having the same thickness as the pedestal is interposed at a position in front of the installation portion of the wind direction adjusting blade group of the air conditioning case body so as to avoid interference with the blade group.

[0009]

According to the wind direction adjusting device of the present invention, it is divided into a plurality of groups of wind direction adjusting blades composed of a plurality of adjusting blades for adjusting the right and left wind directions blown out from the device, and is provided inside the air conditioning case body. It is rotatably supported around a rotation shaft. Each adjusting vane of the plurality of wind direction adjusting vane groups is formed on one surface of the same number of pedestals as the number of groups having a gear part in a state of standing up integrally with the rotating shaft. For this reason, it is not necessary to assemble a plurality of blades by connecting them with an interlocking rod or a link as in the conventional case. Further, in general, one end of each blade of the blade group is set as a free end, so that the ventilation resistance in the air conditioning case is reduced, and the set air distribution characteristic is obtained.

Further, when a plurality of wind direction adjusting blade groups are incorporated inside the air-conditioning case body, the gear parts are in mesh with each other, and the turning operation member is turned to pass through the respective gear parts. A plurality of wind direction adjusting blade groups are simultaneously rotated in opposite directions. At the time of this rotation, if, for example, two groups of wind direction adjusting blades come closer to the front, the air distribution characteristics blown out from the air direction adjusting device have a concentrated wind characteristic that concentrates toward the occupant. When the wind direction adjusting vane groups of are parallel, the air distribution characteristics have a parallel wind characteristic in which a uniform air flow is directed to the occupant, and further, two wind direction adjusting vane groups expand in the separating direction at the front. Then, the air distribution characteristic has a diffused air characteristic that diffuses left and right toward the occupant.

Further, since each of the pedestals is made of a plate material having a predetermined thickness, when the pedestal is installed on a part of the bottom portion of the air conditioning case body, the pedestal protrudes inward from the bottom portion of the air conditioning case body. Therefore, turbulence is caused in the flow of wind passing through the air conditioning case body, and the above-mentioned air distribution characteristics are greatly affected. Therefore, in the present invention, the bottom surface of the air conditioning case body is set to be flush with the upper surface of the pedestal behind the installation portion of the wind direction adjusting blade group, and the thickness of the pedestal is formed in the step portion formed in front of the air conditioning case body. By disposing a flat spacer having a thickness equal to the height, the influence of the air distribution characteristics due to the step is eliminated as much as possible.

It has blades 11. The two sets of wind direction adjusting vertical blades 12 and 13 are formed symmetrically and extend in the vicinity of the vertical blades 11 and 11 arranged at one short side end of the pedestals 12a and 13a. The end portions of the pedestals 12a and 13a facing each other are composed of gear portions 12b and 13b. Rotation shafts 12c and 13c are respectively provided at the centers of rotation of the respective gear portions 12b and 13b.
3c is integrally formed with the blades 11 and 11 arranged at the center of each of the blade groups 12 and 13 of the above-mentioned three blades. Further, the upper and lower ends of the rotary shafts 12c and 13c project from the upper ends of the blades 11 and the lower surfaces of the pedestals 12a and 13a, respectively.
The length of the rotation shaft end projecting downward from the pedestal 12a of the first wind direction adjusting vertical blade group 12 is the length of the rotation shaft end projecting downward from the pedestal 13a of the second air direction adjusting vertical blade group 13. It is set longer than the length.

The first and second wind direction adjusting vertical vane groups 12 and 13 thus configured have their gears 12b and 13 respectively.
As shown in FIG. 2, the parts b are meshed with each other and housed and supported inside the air conditioning case body 10. Therefore,
As shown in FIG. 1, when the finisher 17 is fitted to the enlarged portion 10a at the open end of the enlarged portion 10a of the air conditioning case body 10 and the rear end of the finisher 17, the first and second
Recesses 10d and 17a that form support holes for rotatably supporting the ends of the rotating shafts that vertically project from the vertical direction blade groups 12 and 13 are formed. After the first and second wind direction adjusting vertical blade groups 12 and 13 are rotatably accommodated and supported inside the air conditioning case body 10,
First wind direction adjusting vertical blade group 1 protruding downward from the bottom of the
A dial, which is the operation member 14, is attached to the shaft end of the two rotating shafts 12c. According to the illustrated example, the dial 14 has a substantially semicircular shape as long as it can be rotated within the rotation limit.

Further, when the finisher 17 is fitted in the enlarged portion 10a of the air conditioning case body 10, a space portion is formed between the finisher 17 and the first and second wind direction adjusting vertical blade groups 12, 13 described above. In the state in which the plurality of horizontal blades 16 are rotatably connected by the interlocking rod 15, the left and right axial ends of the horizontal blades 16 are connected to the horizontal blade supporting holes formed between the air conditioning case body 10 and the finisher 17. Inserted and supported. The horizontal blade support holes are recesses 1 formed at the left and right front ends of the enlarged portion 10a of the air conditioning case body 10 and the left and right rear ends of the finisher 17.
0e and 17b are formed by abutting. The wind direction adjusting device 1 of the present invention thus assembled has the appearance shown in FIG. Although the air-conditioning case body 10 and the finisher 17 are fixed by the screw 18, the fixing means may be engagement with a claw piece.

According to the wind direction adjusting device of the illustrated example having such a configuration, the plurality of vertical blades 11 for adjusting the left and right wind directions blown out from the device are the first and second wind direction adjusting blade groups 12 and 13. Air conditioning case body 1 divided into two groups
0 is rotatably supported in the left and right around the vertical rotation shafts 12c and 13c. Each of the three vertical blades 11 of each of the first and second wind direction adjusting blade groups 12 and 13 has first and second pedestals 1 that partially include gear portions 12b and 13b.
It is formed on the upper surfaces of 2a and 13a in a state of standing upright together with the rotary shafts 12c and 13c. Therefore, it is not necessary to assemble a plurality of blades by connecting them with an interlocking rod or a link as in the conventional case. Further, particularly in this embodiment, since the upper ends of the vertical blades 11 are free ends, the ventilation resistance passing through the inside of the air conditioning case body 10 is reduced, and turbulent flow does not occur in the case. Therefore, the air distribution characteristics are likely to be as set.

When the two groups of first and second wind direction adjusting blades 12 and 13 are incorporated in the air conditioning case body 10, the gear parts 12b and 13b are in mesh with each other, and the dial 14 Is rotated left and right, the pedestal 12a of the first wind direction adjusting blade group 12 is rotated left and right,
The gear portion 13b of the second pedestal 13a meshing with the gear portion 12b of the pedestal 12a is rotated in the opposite direction at the same rotation angle, and the three vertical blades 11 standing on the upper surface of the pedestal 13a are rotated in the same direction. Turn all at once.

FIG. 5 is a view for explaining the orientation of the first and second wind direction adjusting blade groups 12 and 13 at this time. As shown in FIG. 5A, the first and second wind direction adjusting blade groups 12 are shown. , 1
When 3 is close to the front, the wind distribution characteristic blown out from the wind direction adjusting device has a concentrated wind characteristic that concentrates toward the occupant. In addition, as shown in FIG.
When the second wind direction adjusting blade groups 12 and 13 are in the parallel state, the air distribution characteristic has the parallel air characteristic in which a uniform air volume is directed to the occupant. Further, in FIG. 7C, the first and second wind direction adjusting blade groups 12 and 13 are in a state of expanding in the separating direction at the front, and the air distribution characteristics in this case are diffused air characteristics that diffuse to the left and right toward the occupant. Have.

In this embodiment, in particular, the arrangement of the first and second wind direction adjusting blade groups 12 and 13 inside the air conditioning case body 10 is such that the blade groups 12 and 13 have concentrated wind characteristics as shown in FIG. 5 (a). Vertical blades 11, which are located at the left and right ends of the left and right blade groups 12, 13, when rotated to a position having
The rear ends (upper part of the figure) of 11 are air-conditioning case bodies 1, respectively.
Since it is set to contact the inner wall surface of 0
The air passing through the wind direction adjusting device 1 is completely concentrated and blown out in the front center. Further, in the present embodiment, when the first and second wind direction adjusting blade groups 12 and 13 are rotated to the position having the diffused wind characteristic shown in FIG. Since the rear ends of the left and right vertical blades 11 located on the side are in contact with each other,
The air passing through the wind direction adjusting device 1 is efficiently diffused forward.

Since the pedestals 12a and 13a are both made of a plate material having a predetermined thickness, when the pedestals 12a and 13a are installed on a part of the bottom of the air conditioning case body 10, the pedestals 12a and 13a are also installed.
The a and 13a are projected from the bottom portion of the air conditioning case body 10, causing turbulence in the flow of wind passing through the inside of the air conditioning case body 10, which has a great influence on the above-mentioned air distribution characteristics. Therefore, in the present invention, as shown in FIG.
In the rear of the installation portion of the wind direction adjusting blade groups 12 and 13, the height of the internal space of the air conditioning case body 10 is equal to the height of the vertical blades 11, and the ceiling surface and the bottom surface are aligned with the upper and lower end surfaces of the vertical blades 11. In this case, the first and second wind direction adjusting blade group 1
A step is formed in front of the air conditioning case body 10 including the installation parts 2 and 13 as shown in FIG.
The bottom of the air conditioning case body 10 is lowered by the thickness of a and 13a. Naturally, this step also greatly changes the air distribution characteristics. Therefore, in the illustrated embodiment, the pedestal 12 on the front bottom surface of the pedestal 12a, 13a is indicated by a broken line in FIG.
A flat plate-like spacer 19 having a thickness equal to the thickness of the pedestals 12a and 13a is arranged at a position where it does not interfere with a and 13a, so that the influence of the air distribution characteristic due to the step is eliminated as much as possible.

FIG. 6 shows another embodiment of the first and second wind direction adjusting vertical blade groups applied to the present invention. In this embodiment, the difference from the above-mentioned embodiment is that each wind direction adjusting vertical blade group 12 ', 13' is a top plate 12'd, 1 '.
3'd, and the top plate 12'd, 1
Due to the presence of 3'd, the rigidity of the first and second wind direction adjusting vertical blade groups 12 ', 13' is increased so that the wall thickness of each vertical blade 11 can be made thinner than that of the above embodiment. The top plates 12'd and 13'd constitute the reinforcing plate material in the present invention. Further, even in this embodiment, the spacer 19
Are arranged at the same position, and a second spacer (not shown) is arranged in the front portion of the top plate 12'd, 13'd of the case body 10.

Although the vertical blades for adjusting the left and right wind directions have been described as the blades for giving various air distribution characteristics in the above-mentioned embodiment, the present invention is not limited to the adjustment of the left and right air distribution characteristics, and has the same configuration. By adopting, it is naturally applicable to the wind direction adjusting device for adjusting the upper and lower air distribution characteristics. Those skilled in the art can easily change the configuration from the above description.

[0024]

As is apparent from the above description, according to the wind direction adjusting device of the present invention, various wind distribution characteristics such as concentrated wind characteristics, parallel wind characteristics and diffused wind characteristics can be reliably obtained with a simple operation. Moreover, the number of parts is smaller than that of the conventional device of this type, and the assembling process is reduced, which not only leads to cost reduction, but also because the air-conditioning case body has no sliding groove or extra shaft hole. There is little loss of air volume, and no wind noise is generated because there are no interfering members such as links or interlocking rods that traverse the case.
