c. Problem to be Solved by the Invention However, according to the above-mentioned prior art, when the vertical fin 103 is deeply inserted into the groove 103, the inclination angle of the vertical fin 103 is limited, and if the vertical fin 103 is too shallow, the operation lever 101 is separated from the groove 103. May occur. In particular, since the vertical fin 103 and the operating lever 101 are in direct contact with each other, there is a problem that the vertical fin 103 becomes heavy during operation.

An object of the present invention is to solve the above-mentioned problems and to provide a ventilator grill capable of smoothly adjusting the wind direction.

d. Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of horizontal fins that integrally rotate in the vertical direction and a plurality of horizontal fins that are arranged on the rear side of the horizontal fins and that operate in conjunction with each other. A plurality of vertical fins that rotate via a shaft in a direction orthogonal to the horizontal fins are provided, and an operation lever that slides along the axial direction of the horizontal fins is attached to one of the horizontal fins, which is in the middle. In a ventilator grill in which an arm is provided on a vertical fin so as to project toward the front side and the arm and the operation lever are rotatably engaged with each other via an axis, a lower portion of the operation lever facing the lower surface of the horizontal fin. The plate is provided with a plurality of protrusions that come into contact with the front and rear portions of the lower surface of the horizontal fin in the same direction as the axial direction of the horizontal fin, and the upper plate of the operation lever has a convex surface that comes into contact with the central portion of the horizontal fin in the front-rear direction. Formed by the above-mentioned ridge and convex surface An extension is formed on the lower surface of the rear end of the horizontal fin while holding the fin, and a protrusion that engages with the rear end of the extension is formed at the tip of the lower plate, and the protrusion of the lower plate is formed. By this, the extending portion on the lower surface of the rear end portion of the horizontal fin is locked to form a gap between the inner surface of the operation lever and the tip of the horizontal fin.

e. Action When the operating lever slides along the horizontal fin, the arm engaged with the operating lever via the shaft moves, and the vertical fin provided with this arm rotates to change its direction. Since the vertical fins interlock with each other, all the vertical fins change their orientations accordingly.

f. Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 7 (a) and (b), reference numeral 1 is a ventilator grill attached to a cold / hot air outlet of an air conditioner of an automobile. The ventilator grill 1 is composed of a ventilator case 2 attached to the outlet and a louver body 3 axially supported by the ventilator case 2 so as to be vertically rotatable.

The louver body 3 is formed by integrally molding a plurality of horizontal fins 4, and a plurality of vertical fins 5 are pivotally supported on the upper and lower surfaces of the louver body 3 behind the horizontal fins 4. The vertical fins 5 are pivotally supported on the rear side by a common connector 6 and interlock with each other.

Reference numeral 7 denotes an operation lever which is slidably attached to one of the horizontal fins 4 along the axial direction of the horizontal fin 4. The operation lever 7 has upper and lower plates 7a, 7a as shown in FIGS. 7
It is a U-shaped member that holds the upper and lower surfaces of the horizontal fin 4'at b. The lower side plate 7b of the operating lever 7 is provided with a projection 8 which engages with the rear end edge of the horizontal fin 4'on the plate surface, and an engagement groove 9 at the tip, and engages with this engagement groove 9. Axis
As shown in FIGS. 10 (a), 10 (b), and 10 (c), 10 is provided on the upper surface of an arm 11 which is integrally provided with one of the vertical fins 5. A notch 12 is provided at the front of the vertical fin 5'at a position corresponding to the plate 7b.

On the surface of the operating lever 7 facing the horizontal fin 4 ', a convex surface 13 is formed on the upper plate 7a so as to abut the central portion of the horizontal fin 4'in the front-rear direction as shown in FIG. 4'A plurality of ridges abutting on the front and rear of the lower surface
14 is provided in the same direction as the axial direction of the horizontal fin 4 '. On the other hand, on the lower surface of the rear end portion of the horizontal fin 4'supporting the operation lever 7, an extending portion 15 engaging with the protrusion 14 is formed, and the horizontal fin 4'is formed.
A gap 16 is formed between the tip of the control lever 7 and the operating lever 7.
On the plate surface of the horizontal fin 4 ', projections for restricting the sliding range of the operating lever 7 are provided on both sides of the horizontal fin 4'.

According to the above configuration, when the operation lever 7 is held and operated up and down, the louver body 3 rotates up and down and the lateral fins 4 move up and down. Next, when the operating lever 7 is slid laterally, the operating lever 7 slides along the horizontal fins 4 ',
The shaft 10 provided on the arm 11 of the vertical fin 5'is moved through the engagement groove 9. In this way, the shaft 10 rotates and moves laterally, changing the orientation of the vertical fins 5'to lateral direction. Since the vertical fins 5'and the other vertical fins 5 are connected by the connector 6, the vertical fins 5'and the other vertical fins 5 also change their orientation. The upper plate 7a of the operating lever 7 has a convex surface
Since 13 is formed and the ridge 14 is formed on the lower plate 7b, the contact area with the horizontal fin 4'is reduced, and the smooth movement is performed.

g. Effect of the Invention As described above, according to the ventilator grill of the present invention, a plurality of horizontal fins that integrally rotate in the vertical direction and a plurality of horizontal fins that are disposed on the rear side of the horizontal fins are interlocked with each other to operate as described above. A plurality of vertical fins that rotate via a shaft in a direction orthogonal to the horizontal fins are provided, and an operation lever that slides along the axial direction of the horizontal fins is attached to one of the horizontal fins, which is in the middle. In a ventilator grill in which an arm is provided on a vertical fin so as to project toward the front side and the arm and the operation lever are rotatably engaged with each other via an axis, a lower portion of the operation lever facing the lower surface of the horizontal fin. The plate is provided with a plurality of protrusions that come into contact with the front and rear portions of the lower surface of the horizontal fin in the same direction as the axial direction of the horizontal fin, and the upper plate of the operation lever is provided with
A convex surface is formed in contact with the center of the horizontal fin in the front-rear direction, and the projection and the convex surface hold the horizontal fin, and an extension is formed on the lower surface of the rear end of the horizontal fin. A protrusion to be fitted is formed at the tip of the lower plate, and the protrusion of the lower plate locks the extending portion of the lower surface of the rear end of the horizontal fin to connect the inner surface of the operation lever and the tip of the horizontal fin. Since a gap is formed between the horizontal fins, the horizontal fins can be firmly gripped by the operating lever, so that the sliding operation can be performed smoothly without rattling the operating lever. In addition, a protrusion that engages with the rear end of the extending portion provided on the lower surface of the rear end of the horizontal fin is formed at the tip of the lower plate, and the rear end of the horizontal fin is formed by the protrusion of the lower plate. Since the gap is formed between the inner surface of the operation lever and the tip of the horizontal fin by locking the extending portion of the lower surface, the contact area between the horizontal fin and the inner surface of the operation lever is small. Since its sliding resistance is small, it can be easily grasped with a fingertip and moved, and no sliding noise is generated during operation.
