Regarding the register of.

Conventionally, as a round register having a circular air outlet in a cylindrical frame, a plurality of blade plates are radially arranged in a substantially cylindrical nozzle housing, and each blade plate is interposed via a support shaft above and below the blade plate. Patent Document 1 below knows a register having a structure in which a damper is rotatably supported and a damper is arranged at a rear portion in a nozzle housing so as to open and close a ventilation path.

This register has a cylindrical nozzle with a support base mounted in a cylindrical nozzle housing, and a plurality of blade plates are rotatably provided inside the support base via a radial support shaft. A dial knob is provided on a cylindrical guide portion at the center of the support base so as to be rotatably supported via a fixing knob and movably movable in the axial direction. Further, a pair of semi-circular dampers are provided at the rear portion in the nozzle housing so as to be openable and closable via a rotation shaft in the radial direction, and a pair of dampers are provided on a support base via a bevel gear and a connecting shaft. It is connected to the dial knob provided in the center, and the damper opens and closes by rotating the dial knob.

A bezel 9 is fitted to the downstream end of the retainer 1 by locking the locking portion 91 to the locking claw 13 on the retainer side, and the front portion of the rotating louver 2 is fitted in the bezel 9 in FIG. Appears like.

The register having the above configuration is used by being attached to, for example, an air outlet of an air conditioner provided on an instrument panel of an automobile. When changing the blowing direction of the register, the rotary louver 2 is tilted by holding the front portion of the rotary louver 2 serving as the operation unit 6, for example, the operation knob 61 or the annular operation frame 28. At this time, since the operation unit 6 constitutes the whole including the operation knob 61 of the rotary louver 2 and the annular operation frame 28, the user can easily hold the rotary louver 2 by holding the annular operation frame 28 or the like. The tilting operation can be performed to adjust the blowing direction.

Further, when opening / closing the damper device 7 or adjusting the air volume, the operation knob 61 of the rotating louver 2 serving as the operation unit 6 or the annular operation frame 28 is held around the axis (center line S2) of the universal joint 8. Rotate with. At this time, the entire rotating louver 2 including the cylindrical frame 20, the operation knob 61, the annular operation frame 28, and the like rotates around the center line S2, and the rotational power is transferred to the output shaft 81 via the universal joint 8. Be transmitted.

As a result, the bevel gear 77 attached to the end of the output shaft 81 rotates, and the semicircular dampers 71 and 72 of the damper device 7 rotate in opposite directions via the gear pieces 75 and 76. As a result, as shown in FIGS. 20 and 21, the damper device 7 is opened or closed, or the opening angles of the semicircular dampers 71 and 72 are adjusted, and the ventilation passage 15 is opened or closed, or the air volume is increased. Adjustments are made.

On the other hand, when the movable fin 23 of the rotating louver 2 is rotated around its support shafts 24 and 26, the operating knob 61 is held and pulled toward the front as shown in FIG. At this time, the knob shaft member 4 slides in the axial direction with respect to the fin shaft support portion 3, and the guide groove 41 of the knob shaft member 4 acts on the guide pin 25 of the movable fin 23 to cause the movable fin 23 to support the movable fin 23. Rotate around 24 and 26. As a result, as shown in FIG. 19, each movable fin 23 is in an inclined state with respect to the axial direction of the ventilation passage 15, and the inclined movable fin 23 diffuses the blown air and blows a mild wind (diffused wind).

On the other hand, when changing from the mild wind to the spot wind, the operation knob 61 is pushed in as shown in the right figure of FIG. As a result, the knob shaft member 4 slides rearward with respect to the fin shaft support 3, and the movable fin 23 is moved to the support shaft 24 by the action of the guide groove 41 of the knob shaft member 4 and the guide pin 25 of the movable fin 23. It rotates around 26, and as shown in FIG. 5, each movable fin 23 is in a parallel state with respect to the axial direction of the ventilation path 15, and a straight spot wind is blown.

In this way, by pushing or pulling back the operation knob 61 with respect to the knob shaft support portion 27 and sliding the knob shaft member 4 in the axial direction, it is possible to easily adjust from spot wind to mild wind (diffusion wind). By rotating the entire rotary louver 2 (operation unit 6), the damper device 7 can be easily opened and closed and the air volume can be easily adjusted. Since the damper device 7 is opened and closed and the air volume is adjusted by rotating the entire rotating louver 2 (operation unit 6), the rotation adjustment of the movable fin 23 by the sliding operation of the operation knob 61 is not affected. ..
