[0023]
The main body 1 of the wind direction adjusting device has a rectangular tube-like case 2 having an opening 2a opened on the front surface, and an opening is provided inside an air outlet, for example, opened at the top of an instrument panel (not shown). 2a can be attached facing forward.
[0024]
In the opening 2 a of the case 2, a plurality of blades 3 are provided in the horizontal direction at intervals in the vertical direction, and the shaft pin 3 a protruding from one end side of each blade 3 is connected to the case 2. A notch-shaped pin receiver 2c formed on one side plate 2b is rotatably fitted.

A shaft pin 3a and a connecting pin 3b are projected from the other end of each blade 3, and the shaft pin 3a is rotated around a pin receiver 4a of a spacer 4 assembled along the opening edge of the other side plate 2b. The shaft pins 3a are not detachable from the pin receivers 2c and 4a by the finisher 8 which is movably fitted and is in contact with the opening 2a.
[0026]
The finisher 8 is formed of a plate body that is curved in the vertical direction. When the blades 3 are erected along the curvature of the finisher 8, openings 8a that are closed by the blades 3 are opened. On the side of 8a, a long hole 8b from which an operation portion 6f of an operation dial 6d to be described later projects is formed, and on both sides of the finisher 8, one outer surface of the case 2 and the outer surface of the cover 7 protrude. Locking pieces 8c whose tip ends engage with the provided locking claws 7a project backward.
[0027]
The spacer 4 is fitted to the opening edge 2d of the case 2, and an arc-shaped long hole 4b centering on the pin receiver 4a is formed in the vicinity of each pin hole 4a. The connecting pin 3b projecting from the through hole is inserted into the guide holes 5a of the slide link 5 provided on the outer surface of the spacer 4 through the long holes 4b.
[0028]
Each guide hole 5a has a guide hole 5a located in the middle portion of the slide link 5 substantially horizontally, a guide hole 5a located above the middle portion in a substantially square shape, and a guide hole 5a located below the middle portion. Are formed in a substantially inverted-H shape, and projecting portions 5b project rearwardly at the upper and lower portions of the slide link 5, and pins 5c are provided on the inner surface of the projecting portion 5b on the proximal end side. A pin 5d protrudes from the outer surface.
[0029]
Of these pins 5c and 5d, the pin 5c protruding from the base end is fitted into a substantially C-shaped groove 2f formed in the side plate 2b of the case 2 and protruded from the tip side. 5d is fitted in substantially sickle-shaped cam grooves 6b formed in the pair of intermediate gears 6a constituting the mode selection means 6, respectively.
[0030]
The mode selection means 6 selects a normal mode for adjusting the air direction of the air blown from the air outlet and a wind direction characteristic mode for concentrating or diffusing the air blown from the air outlet. An operation dial 6d having the intermediate gear 6a and a pinion 6c simultaneously meshing with the intermediate gear 6a is accommodated in a cover 7 provided parallel to the side plate 2a.
[0031]
As shown in FIGS. 2 and 3, the operation dial 6d has a shaft hole 6e formed at the center thereof rotatably supported by a support shaft 2g protruding from the outer surface of the case 2, and has a front outer periphery. The operation portion 6f is projected from the long hole 8b formed in the finisher 8 to the front surface of the finisher 8, and a mark 6g indicating the operation position is provided on the outer peripheral surface of the operation portion 6f. , Formed by concave grooves and triangular marks.
[0032]
Further, a substantially fan-shaped cam 6h projects from the outer peripheral portion on the rear side of the operation dial 6d, and an arc-shaped cam groove 6j is formed along the outer peripheral surface of the cam 6h. The lower end is bent toward the center of the operation dial 6d to form a bent portion 6k, and a pin 9a protruding from the tip of the shutter opening / closing lever 9 is fitted into the cam groove 6j.
[0033]
On the base end side of the shutter opening / closing lever 9, a prismatic shaft rod 9b is projected in the direction opposite to the pin 9a. The shaft rod 9b is connected to the case 2 through a bearing hole 2h opened in the side plate 2b of the case 2. And is inserted into a shaft hole 10 a of a shutter valve 10 provided in the case 2.
[0034]
The shutter valve 10 is formed of a plate body that can rotate within the case 2, and is rotatably supported on the side plate 2 b of the case 2 by a shaft pin 10 b that protrudes on the opposite side of the shaft hole 10 a. In addition, seal members (not shown) are attached to both ends of the shutter valve 10 to prevent the air from leaking by contacting the inner surface of the case 2 when the shutter valve 10 is closed.
[0035]
Next, the operation of the thus configured wind direction adjusting device will be described.
[0036]
In the case of using in the normal mode, the normal mode is selected as shown in FIG. 3 by making the concave groove of the mark 6g provided on the operation dial 6d of the mode selection means 6 approximately at the center of the long hole 8b.
[0037]
As a result, the slide link 5 is at the reverse end, and the pin 5d protruding from the tip of the protruding portion 5b of the slide link 5 is located at the connecting portion of the arc-shaped portion and the bent portion of the cam groove 6b. Since the blade 3 is held in a horizontal state, the air blown from the air outlet is adjusted in the direction of the parallel wind in the horizontal direction by the blade 3.
[0038]
Further, from this state, when the air blowing direction is adjusted upward, for example, the operation portion 6f of the operation dial 6d is rotated upward.
[0039]
As a result, the slide link 5 is moved downward as shown in FIG. 4, so that each blade 3 connected to the slide link 5 via the connecting pin 3b rotates counterclockwise about the shaft pin 3a. Thus, the air blown out from the air blowing port is adjusted in the direction of the upward parallel wind.
[0040]
Further, when the air blown from the air outlet is diffused and blown to the occupant, the operation portion 6f of the operation dial 6d is further rotated upward to select the wind direction characteristic mode.
[0041]
As a result, the pinion 6c provided on the operation dial 6d rotates the intermediate gear 6a in the clockwise direction, so that the slide link 5 is advanced to the position shown in FIG. 5 by one end of the cam groove 6b formed in the intermediate gear 6a. The blade 3 at the intermediate position is held in the horizontal position by the guide hole 5a of the slide link 5, and the blade 3 above the intermediate position is rotated counterclockwise and turned upward, and at the lower side from the intermediate position. Since the blades 3 are rotated downward in the clockwise direction, the air blown from the air blowing ports is diffused by the blades 3 and blown to the occupant.
[0042]
On the other hand, when the air blowing direction is adjusted downward, for example, from the normal mode state shown in FIG. 3, the operation portion 6f of the operation dial 6d is rotated downward.
[0043]
As a result, the slide link 5 is moved upward as shown in FIG. 6, so that each blade 3 connected to the slide link 5 via the connecting pin 3b is rotated clockwise around the shaft pin 3a. Thus, the air blown from the air outlet is adjusted in the direction of the downward parallel wind.
[0044]
Further, in order to block the air blown from the air outlet, if the operation portion 6f of the operation dial 6d is further rotated downward, the pinion 6c provided on the operation dial 6d causes the intermediate gear 6a to move counterclockwise. In order to rotate, the slide link 5 is advanced to the position shown in FIG. 7 by the other end of the cam groove 6b formed in the intermediate gear 6a, and all the blades 3 are rotated clockwise by the guide holes 5a of the slide link 5. As a result, the blades 3 are aligned on the surface along the curved surface of the finisher 8 to close the opening 8 a of the finisher 8.
[0045]
At the same time, the pin 9a fitted to the cam 6j protruding from the operation dial 6d is moved toward the center of the operation dial 6d by the bent portion 6k of the cam 6j, and the shutter opening / closing lever 9 is rotated counterclockwise. Therefore, the shutter valve 10 closes the inside of the case 2 and almost completely blocks the air blown from the air outlet.
[0046]
In the above-described embodiment, the case where the air blowing characteristic mode is selected by the mode selection means 6 has been described so that the air blown out from the air blowing port is diffused. However, the guide hole 5a formed in the slide link 5 has been described. The guide hole 5a located at the middle part of the slide link 5 is substantially horizontal, the guide hole 5a located above the middle part is substantially reverse-shaped, and the guide hole 5a is located below the middle part. When the wind direction characteristic mode is selected, the air blown out from the air outlet can be concentrated in the occupant direction.
[0047]
Further, as in the modification shown in FIGS. 8 and 9, the direction of the cam groove 6b formed in the intermediate gear 6a may be reversed from that in the above embodiment. In this case, the parallel wind is directed upward as shown in FIG. When the slide link 5 reaches the forward end and the operation dial 5d is further rotated upward, the slide link 5 moves backward as shown in FIG. 9 so that the air blown out from the air outlet is diffused. become.
[0048]

Since the selection can be made only by changing the rotation direction, the operability is very good.
[0050]
In addition, a shutter valve that closes the inside of the case in conjunction with the blade when the air outlet is closed by the blades is provided in the case so that it can be opened and closed. Since the inside is also closed, the air blown out from the air blowing port can be almost completely blocked.
[0051]
The mode selection means includes a single operation dial for continuously selecting the normal mode and the wind direction characteristic mode, an intermediate gear rotated by the operation dial, and a longitudinal movement engaged with a cam groove formed in the intermediate gear. Each blade linked to the slide link is continuously rotated to the normal mode position and the wind direction characteristic mode position by moving the slide link back and forth via an intermediate gear with an operation dial. Since the normal mode and the wind direction characteristic mode can be selected continuously with a single operation dial, the operability is significantly improved compared to the case where the conventional mode is selected by another operation means. .
[0052]
In addition, since the rotation of the operation dial is transmitted to the slide link by a gear, the operation of the mode selection means becomes smooth, which makes it easy to select the normal mode and the wind direction characteristic mode with a small operation force, and the mode selection means. Since it can be configured with a small number of parts, the workability at the time of assembling is good and the configuration can be made compact, so that the wind direction adjusting device can be miniaturized.

In addition, the operation part of the operation dial protrudes from the front surface of the finisher attached to the opening of the case, and the slide link is formed by fitting a connecting pin protruding from each blade into the guide hole formed in the slide link. Since the blades are interlocked with each other, the normal mode and the wind direction characteristic mode can be selected continuously by rotating the operation portion of the operation dial with a finger, so that the operability is very good.
[0054]
Moreover, if the case is installed at the top of the instrument panel, the mode selection means can be operated easily from the driver's seat or passenger seat, so that the operability is good and the air blown from the air outlet is circulated throughout the vehicle interior. Therefore, the air conditioning in the passenger compartment can be performed satisfactorily.
