Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wind direction control device for an air conditioner mounted on a vehicle, for example.

[Prior Art] This type of wind direction control device is constructed by arranging a plurality of blades in parallel to each other in an opening of a housing, and the direction of the air discharged from the opening is controlled by the blades. . The angle of inclination of each blade relative to the opening can be changed by a drive source such as an electric motor, and between the output shaft of the motor and the blade,
A cam mechanism, a link mechanism, etc. are provided, whereby the rotational motion of the output shaft is converted into parallel motion, and the blade is rotationally displaced.
In such a device, when attempting to move the blade manually, the cam mechanism and link mechanism must also be moved, which poses a problem in that a very large amount of force is required. For this reason, various wind vent control devices have been developed that allow the blades to be easily moved by hand, independent of a drive source such as a motor.

For example, the air outlet control device shown in FIGS. 4 and 5 was proposed by the applicant of the present invention on May 20, 1985 (Utility Application No. 1987-73490).

In FIG. 4, a plurality of blades 13 are attached to each opening 12 formed in the front surface of the housing 11 in parallel with each other. Blade 13
extends from the upper side to the lower side of the opening 12, is swingably supported on each side, and controls the direction of the air flow discharged from the opening 12. 1 opening 1
The blades 13 provided on the housing 11 are connected to each other so that they are always parallel to each other, and a pin 14 attached to one of the blades 13 protrudes from the upper surface of the housing 11 and is connected to the protruding end thereof. Member 15 is formed. A moving member 16 provided on the upper surface of the housing 11 so as to be able to reciprocate in the left-right direction in the figure is connected to the connecting member 15 via a pin 17 of a transmission mechanism, which will be described later. Moving member 16
is driven by a motor (not shown) and displaced in the left-right direction, thereby changing the direction of the blade 13 via the connecting member 15. Note that the switch 18 is for driving the motor.

The moving member 16 has a plate-shaped portion 16a that slides on the upper surface of the housing 11, and an overhanging portion 16b that extends toward the connecting member 15 side. The plate-shaped portion 16a is the fifth
As shown in the figure, it has an elongated hole 25 extending in the direction of displacement of the moving member 16, and a pin 26 erected on the upper surface of the housing 11 is inserted into the elongated hole 25. A leaf spring 27 and a washer 28 are press-fitted into the protruding portion of the pin 26 from the elongated hole 25, so that the movable member 16 is pressed against the upper surface of the housing 11 with a constant force. The overhanging portion 16b is connected to the plate-shaped portion 16a by a guide plate 16c, and an auxiliary plate 16d is connected in parallel to the guide plate 16c on the opposite side from the guide plate 16c. These guide plates 16c and support plates 16d are formed on the upper surface of the housing 11 and extend in parallel to a pair of rails 3.
6, thereby allowing the moving member 16 to reciprocate along the rail 36.

The transmission mechanism 31 includes the overhang portion 16b and the guide plate 16.
A pin 17 is housed in a portion surrounded by the catcher plate 16d and the pin 17 extends from the upper surface of the transmission mechanism 31.
engages with a long hole 29 bored in the overhang portion 16b in a direction parallel to the rail 36. As shown in FIG. 5, the transmission mechanism 31 includes a support section 33 having four arm sections 32, four pads 35 inserted into holes formed at the tips of each arm section 32, and each pad 35. It has a spring 34 that urges the gap to be widened. The pad 35 is biased by the spring 34 and comes into sliding contact with the guide plate 16c and the auxiliary plate 16d. pin 1
7 is provided upright on the upper surface of the support portion 33 and engages with the elongated hole 29, thereby allowing the transmission mechanism 31 to slide relative to the moving member 16. Also, the pin 17 has a long hole 29.
The connecting member 15 projects upwardly from the projecting portion 16b through the connecting member 15, and the projecting portion fits into the groove 15a of the connecting member 15.

Butt 35 and guide plate 16c or auxiliary plate 16
When the moving member 16 is displaced, the frictional force acting between the moving member 16 and the connecting member 15 can be transmitted to the connecting member 15
Conversely, when moving the blade 13 manually, the moving member 16
The size is such that the transmission mechanism 31 can be displaced without moving the transmission mechanism 31.

Although the wind direction control device described above allows the blades to be easily moved by hand, it has the following problems.

[Problems to be solved by the invention] When assembling the transmission mechanism 31 to the moving member 16,
The spring 34 must be compressed and then fitted in a direction perpendicular to the force that compresses the spring 34, resulting in poor assembly performance.

Further, the sliding resistance between the transmission mechanism 31 and the moving member 16 varies greatly due to variations in the distance between the guide plate 16c and the auxiliary plate 16d and the distance between the springs 34 and the butts 35.

The present invention aims to solve the above-mentioned problems, improve assembling performance, and suppress variations in sliding resistance.

[Means for Solving the Problems] To achieve the above object, the present invention includes a housing having an opening, and a housing extending from one side of the opening to the other side and sliding into the opening. a blade that is freely supported and controls the direction of airflow discharged from the opening; a connecting member that is fixed to the blade and swings together with the blade;
The blade includes a drive mechanism having a moving member that reciprocates, and a transmission mechanism that is connected to the connecting member and is slidable with respect to the moving member. In a wind direction control device that is rotatably displaced by being transmitted via a connecting member, and is rotatably displaceable independently of the drive mechanism by forcibly generating a relative displacement between the transmitting mechanism and the moving member. The moving member is provided with a connecting portion having a long hole extending in the direction of reciprocating motion, and the transmitting member is provided with a protruding portion that abuts one side of the connecting portion and is loosely fitted into the long hole. a sliding member that contacts the other side of the connecting portion; and a locking member that is locked to the protruding portion from the other side of the connecting portion;
a biasing means provided between the sliding member and the locking member so as to bring the sliding member and the supporting portion into contact with the connecting portion with a predetermined load; and an engaging portion with the connecting member; It was constructed from .

[Operation] Therefore, according to the above configuration, when assembling the transmission mechanism to the moving member, the direction in which the biasing means is retracted and the direction in which the locking member is assembled are the same, making the assembly very easy. becomes.

Furthermore, since the sliding resistance between the transmission mechanism and the moving member is affected only by the dimensions of the protrusion and the spring, variations in sliding resistance can be suppressed compared to conventional devices.
