Description

  The present invention relates to an air outlet. More specifically, the present invention relates to a plurality of wind direction control fins arranged to be rotatable at a required interval to an air outlet of a cylindrical case member, and these wind direction control fins are connected to each other. It is related with the air outlet which can carry out the attitude | position displacement of all the wind direction control fins synchronously with this connecting member.

  Various vehicle interior members such as an instrument panel, a floor console, and a roof panel are installed in a vehicle passenger compartment such as a passenger car. An air outlet connected to the air conditioner unit through an air duct is disposed at a required position of these vehicle interior members, and temperature-controlled air sent from the air conditioner unit is directed in an appropriate direction in the vehicle passenger compartment. It comes to blow out. Many of these air outlets have a wind direction control mechanism for adjusting the blowing direction of temperature-controlled air. When these air outlets are roughly classified from structural aspects, they are composed of (a) a plurality of interlocking wind direction control fins. Further, it can be classified into “fin type”, (b) “barrel type” in which a wind direction control member in which a plurality of wind direction control fins are fixedly formed is disposed in a cylindrical main body, and the like.

  FIG. 9 is a schematic perspective view showing an example of a conventional fin-type air outlet, and FIG. 10 is a partial perspective view showing a part of the air outlet in a broken direction in order to show a wind direction control mechanism. 11 is a front view of the air outlet. The air outlet 10 has a plurality of (five in the drawing) first airflow direction control fins (five shown in the figure) disposed at a required interval in the vertical direction in a horizontal posture at the air outlet 14 of the cylindrical case member 12. Lateral fins 20 and a plurality of (three in the figure) second wind direction control fins (vertical fins) arranged at required intervals in the lateral direction at the rear side of these first wind direction control fins 20. ) 30 and a cross fin type. Each first wind direction control fin 20 is rotatably disposed on both side walls of the case member 12 with support pins 22 and 22 projecting from both ends in the longitudinal direction, and one end in the longitudinal direction. Connection pins 24 project from the connection pins 24, and these connection pins 24 are connected to a single first connection rod (connection member) 26. Therefore, for example, the structure is such that all the first wind direction control fins 20 can be posture-displaced synchronously by angularly displacing (posture displacement) only the first wind direction control fins 20 positioned at the center in the vertical direction. .

Each of the second airflow direction control fins 30 is rotatably disposed on the upper and lower wall portions of the case member 12 with support pins 32 and 32 projecting from both end portions in the longitudinal direction, and at one end portion in the longitudinal direction. Connection pins 34 are provided so as to project from each other, and these connection pins 34 are connected to a single second connection rod (connection member) 36. Accordingly, by sliding the knob 38 slidably disposed on the first wind direction control fin 20 located at the upper and lower center in the left and right direction, the angular displacement of the second wind direction control fin 30 at the left and right center through the operation rod 39. (Posture displacement) can be made, and in conjunction with this, all the second wind direction control fins 30 can be posture-displaced synchronously. Such an air outlet is disclosed in, for example, Patent Document 1.
Japanese Patent Laid-Open No. 06-016034

  By the way, in the conventional air outlet 10 mentioned above, the 1st connection rod 26 which connects each 1st wind direction control fin 20 is visually recognized from the air blower outlet 14 as FIG. The problem which causes the deterioration of the texture of a vehicle interior member was inherent. Further, as illustrated in FIG. 11, since the first connecting rod 26 is located inside the case member 12, turbulent flow is generated in the temperature-controlled air that is circulated and guided to the air outlet 14 via the case member 12. There are inherent problems that are likely to occur and cause distribution resistance. Furthermore, when the first wind direction control fins 20 are assembled to the case member 12, the first connecting rods 26 need to be assembled to the first wind direction control fins 20 in advance, and the assembly work of the air outlet 10 is skillful. There is also a problem that assembly failure is likely to occur.

  In addition, since the second air direction control fin 30 is disposed at a portion that is moderately recessed from the air outlet 14, the second connecting rod 36 that connects them is hardly visible and does not affect the appearance. However, since the second connecting rod 36 is located inside the case member 12, there are problems such as a problem of resistance to flow of temperature-controlled air and a problem that assembly failure is likely to occur.

  Accordingly, it is an object of the present invention to provide an air outlet capable of improving the appearance and improving the texture, reducing the flow resistance of the temperature-controlled air, and facilitating assembly work.

In order to solve the above problems and achieve the intended purpose, the present invention provides:
It has a plurality of wind direction control fins arranged to be rotatable at a required interval to the air outlet of the cylindrical case member, and a connecting member for connecting these wind direction control fins to each other. In the air outlet that can displace the wind direction control fin of the
An opening provided in a portion of the wall of the case member and adjacent to each wind direction control fin;
Each of the wind direction control fins protrudes from the axial end portion, and includes a support shaft portion extending outward of the case member through the opening,
In the outside of the case member, the connecting member is connected to a support shaft portion of each wind direction control fin.

  According to the air outlet of the present invention, since the connecting member for connecting the wind direction control fin is disposed outside the case member, the connecting member is hardly visually recognized from the air outlet, and looks bad. In addition, there is a beneficial effect that does not cause a deterioration in the texture of the vehicle interior member. In addition, since the connecting member is located outside the case member, turbulent flow due to the connecting member is not generated in the temperature-controlled air that is guided to flow through the case member to the air outlet, and thus is circulated. Resistance does not increase. Furthermore, the assembling work does not require skill, so that there is an advantage that the assembling work is hardly generated and the assembling work can be facilitated.

  Next, the air outlet according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments.

  An air outlet to which the present application is directed includes a plurality of wind direction control fins arranged to be rotatable at a required interval to an air outlet of a cylindrical case member, and a connecting member that interconnects these wind direction control fins. It has a structure which can carry out the attitude | position displacement of all the wind direction control fins synchronously by this connection member. Therefore, in the embodiment described later, the air outlet 10 illustrated in FIG. 9 and the like is illustrated in the same shape, and the same members / parts as those of the air outlet 10 are denoted by the same reference numerals. .

  1 is an explanatory perspective view showing an air outlet according to a preferred embodiment in a state where a connecting member is disassembled, FIG. 2 is a schematic perspective view showing the embodiment, FIG. 3 is a side view, and FIG. It is the front view shown. The air outlet 40 of the present embodiment basically has a horizontal posture at a predetermined interval in the vertical direction at the air outlet 14 of the cylindrical case member 12 in the same manner as the conventional air outlet 10 illustrated in FIG. A plurality of (five in the drawing) first wind direction control fins (horizontal fins) 20 arranged in the vertical direction and arranged at a required interval in the horizontal direction at the rear side of the first wind direction control fins 20 in a vertical posture. The cross fin type is composed of a plurality of (three shown) second wind direction control fins (vertical fins) 30 provided.

  Each first wind direction control fin 20 is provided with support pins 22, 22 projecting at both ends in the longitudinal direction, and these support pins 22, 22 are opened on both side walls of the case member 12. It is attached in a horizontal posture by being inserted into the support pin 22 and can be rotated around the support pins 22 and 22. Each of the second wind direction control fins 30 is provided with support pins 32, 32 projecting at both ends in the longitudinal direction, and the support pins 32, 32 are formed in the upper and lower wall portions of the case member 12. It is attached in a vertical posture by being inserted into 44 and can be rotated around these support pins 32 and 32.

  In the air outlet 40 of the present embodiment, the first opening 46 is opened at the wall portion (side wall portion) of the case member 12 and adjacent to one end portion of each first wind direction control fin 20. The connecting pin (support shaft portion) 48 projecting from the axial end of each first wind direction control fin 20 can extend (project) outward of the case member 12 through the first opening 46. The length is set. Thereby, outside the case member 12, the connection pin 48 of each 1st wind direction control fin 20 connects with the 1st connection member (connection member) 50 mentioned later, and the structure which each 1st wind direction control fin 20 interlock | cooperates. It is characterized by that. Each of the connecting pins 48 described above protrudes at a position biased toward the rear end side from the end center of the first wind direction control fin 20, and protrudes at a position biased toward the front end side from the end center. The support pins 22 are projected with a required interval (for example, about 1 cm) (FIG. 3).

  The first opening 46 is formed on the front side of the side surface of the case member 12 and has a long hole shape through which the connecting pin 48 of each first wind direction control fin 20 can be freely inserted and has a sufficient wind direction control function. Even if each first wind direction control fin 20 rotates within an angle range (for example, about 35 ° downward (FIG. 5) and upward 35 ° (FIG. 6)), the respective connecting pins 48 do not interfere with each other. The opening size is set. Further, the first connecting member 50 has a connecting hole 52 that is pivotally supported by inserting the connecting pin 48 of each first wind direction control fin 20 in a straight line at every required interval. 20 has a shape that can completely cover the first opening 46 regardless of the posture within the above-mentioned angular range. That is, the first connecting member 50 has a rectangular plate shape that is set to a size larger than that of the first opening 46, and the shutter that always covers the first opening 46 to prevent leakage of temperature-controlled air. It also functions as a member.

  Therefore, when the first wind direction control fin 20 at the center in the vertical direction is operated downward by fingertip operation, as illustrated in FIG. 5, the first connecting member 50 moves upward, and each first wind direction control is performed. The fin 20 rotates about the support pins 22 and 22 and assumes a downward posture. Further, when the first wind direction control fin 20 at the center in the vertical direction is operated upward by fingertip operation, as illustrated in FIG. 6, the first connecting member 50 moves downward, and each first wind direction control is performed. The fin 20 rotates about the support pins 22 and 22 and assumes an upward posture. In any posture, the first connecting member 50 completely covers the first opening 46, and the temperature-controlled air flowing through the case member 12 passes through the first opening 46. It does not leak out of the member 12.

  On the other hand, in the air outlet 40 of the present embodiment, the second opening 56 is opened in the wall portion (upper surface wall portion) of the case member 12 and in a portion adjacent to one end portion of each second wind direction control fin 30. At the same time, a connecting pin (support shaft) 58 protruding from the axial end of each second wind direction control fin 30 extends (projects) outward from the case member 12 through the second opening 56. The length is set. Thereby, on the outside of the case member 12, the second wind direction control fins 30 are interlocked by connecting the connection pins 58 of the second wind direction control fins 30 to the second connection member 60 described later. Each of the connecting pins 58 is protruded from the center of the second wind direction control fin 30 toward the rear end, and protruded from the center of the end toward the front end. The support pins 32 are projected with a required interval (for example, about 1 cm) (FIG. 7).

  The second opening 56 is opened on the rear side of the upper surface of the case member 12 and has a long hole shape through which the connection pin 58 of each second wind direction control fin 30 can be inserted loosely, and has a wind direction control function. Even if each second wind direction control fin 30 is rotated within an angle range that is sufficiently exerted (for example, about 35 ° to the right (FIG. 7) and about 35 ° to the left (FIG. 8)) The opening size is set so that the pin 58 does not interfere. Further, the second connecting member 60 has a connecting hole 62 that is pivotally supported through the connecting pin 58 of each second wind direction control fin 30, and is linearly formed at every required interval. 30 has a shape that can completely cover the second opening 56 regardless of the posture within the above-described angle range. That is, the second connecting member 60 has a rectangular plate shape that is set to a size larger than the second opening 56, and the shutter that always covers the second opening 56 to prevent leakage of temperature-controlled air. It also functions as a member.

  Accordingly, when the knob 38 disposed on the first wind direction control fin 20 at the center of the top and bottom is slid to the left side by the fingertip operation, the second wind direction at the center of the left and right via the operation rod 39 as illustrated in FIG. The control fin 30 is rotated to the left, and accordingly, the second connecting member 60 is moved to the right, and each second wind direction control fin 30 is rotated about the support pins 32 and 32. The posture is left. Further, when the knob 38 is slid to the right side by the fingertip operation, as illustrated in FIG. 8, the second wind direction control fin 30 at the center of the left and right is rotated to the right via the operation rod 39. Accordingly, the second connecting member 60 moves to the left, and each second wind direction control fin 30 rotates about the support pins 32 and 32 to be in the rightward posture. In any posture, the second connecting member 60 completely covers the second opening 56, and the temperature-controlled air flowing through the case member 12 passes through the second opening 56. It does not leak out of the member 12.

  In the air outlet 40 of this embodiment configured as described above, the first connecting member 50 that connects the first wind direction control fins 20 and the second connecting member 60 that connects the second wind direction control fins 30 are the case members 12. Therefore, the first connecting member 50 and the second connecting member 60 are hardly visually recognized from the air outlet 14, the appearance is not deteriorated, and the texture of the vehicle interior member is deteriorated. Will not be invited. Moreover, since the 1st connection member 50 and the 2nd connection member 60 are located in the exterior of the case member 12, these 1st connection is carried out to the temperature-controlled air distribute | circulated and guided to the air blower outlet 14 through this case member 12. Turbulent flow due to the connecting member 50 and the second connecting member 60 does not occur, and thus the flow resistance does not increase. Furthermore, after the first wind direction control fins 20 and the second wind direction control fins 30 are first assembled in the case member 12, the first connection member 50 and the second connection member 60 are attached to the case member 12. Since it is possible to connect from the outside, the assembling work of the air outlet 40 does not require skill, so that it is difficult for an assembly failure to occur and the assembling work can be facilitated.

  In the embodiment described above, the opening shapes of the first opening 46 and the second opening 56 are inserted through the connection pins 48 of all the first wind direction control fins 20 and the connection pins 58 of all the second wind direction control fins 30. However, the first opening 46 and the second opening 56 are formed in a slit shape extending in an arc along the movement trajectory of the connecting pins 48 and 58. You may do it. In this case, since the opening areas of the first opening 46 and the second opening 56 can be reduced, the first connecting member 50 and the second connecting member 60 can also be reduced.

  In the above-described embodiment, the cross fin type air outlet 40 constituted by the plurality of first wind direction control fins 20 and the second wind direction control fins 30 is exemplified. A configuration including only one wind direction control fin 20 and a configuration including only a plurality of second wind direction control fins 30 are also targeted.

  Further, the shape of the case member 12 and the shape of the air outlet 14 are not limited to those of the above-described embodiments, and may be, for example, those formed of a cylindrical case member 12.

  An air outlet according to the present invention includes a plurality of wind direction control fins arranged to be rotatable at a required interval to an air outlet of a cylindrical case member, and a connecting member that connects these wind direction control fins to each other. And an air outlet that can synchronously displace all the wind direction control fins by this connecting member, and is provided in a vehicle interior member or the like.
