  Next, operation | movement of the air blower outlet unit 1 for vehicles in this Embodiment which has the above-mentioned structure is demonstrated using FIGS.

  First, for convenience of explanation, the state shown in FIGS. 7 to 10, that is, the state where the upper ventilation member 14 a closes the upper ventilation path while the lower opening and closing member 14 b opens the lower ventilation path is set as the initial state.

  7 is a front view showing the operation member 6, the link mechanism 7, the upper opening / closing member 14a, and the lower opening / closing member 14b, FIG. 8 is a rear view showing the above-described elements, and FIG. 9 is an operation member. FIG. 10 is a perspective view of each element viewed from the side, and FIG. 10 is a perspective view of each element viewed from the opening / closing member side.

  As shown in FIGS. 7 to 10, in the initial state, the operating shaft 12 is positioned at the end of the linear portion 20b of the slit 20 in the joint arm 8a, and the arc-shaped portion 11a of the slit 11 in the joint arm 8b. Located at the end. Further, while the engagement state between the lock claw 10b of the joint arm 8b and the operation member 6 is maintained, the engagement state between the lock claw of the joint arm 8a and the operation member 6 is released, and the joint arm 8a becomes the operation member. It is located on the side away from 6.

  From the initial state described above, the operation member 6 is rotated by a predetermined angle in the clockwise direction indicated by the arrow in FIG. As a result, the intermediate state shown in FIGS. This intermediate state is a state where the upper ventilation path is opened by the upper opening / closing member 14a and the lower ventilation path is opened by the lower opening / closing member 14b.

  When the operation member 6 is rotated in the direction indicated by the arrow in FIG. 11, the projecting edge 15 of the operation member 6 is also rotated clockwise by the same angle. At this time, since the gear portion 15a formed on the outer periphery of the projecting edge portion 15 and the gear portion 17a of the operating member 17 mesh with each other, the operating member 17 also rotates together with the gear portion 17a in the direction indicated by the arrow in FIG. Operated. When the actuating member 17 rotates, the actuating shaft 12 provided integrally with the actuating member 17 also rotates in the direction indicated by the arrow (counterclockwise) in FIG.

  Since the operating shaft 12 is located in the linear portion 20b of the slit 20 in the joint arm 8a in the initial state shown in FIG. 7, the joint arm 8a is also moved to the arrow in FIG. 11 by rotating the operating shaft 12 as described above. As shown by, it is rotated around the rotation shaft 9a. That is, the joint arm 8a can be turned in a direction approaching the operation member 6. By rotating the joint arm 8a in this manner, the upper opening / closing member 14a can be rotated together with the joint arm 8a in the direction indicated by the arrow in FIG. Thereby, only an upper side ventilation path can be opened.

  On the other hand, with respect to the joint arm 8b, since the operating shaft 12 is located in the arcuate portion 11a of the slit 11 in the joint arm 8b in the initial state, the operating shaft 12 moves to the position shown in FIG. Even so, the operating shaft 12 only moves along the arcuate portion 11 a of the slit 11. Therefore, the joint arm 8b does not rotate during the transition from the initial state to the intermediate state, and the lower opening / closing member 14b is kept open.

  In the process from the initial state to the intermediate state as described above, only the joint arm 8a is rotated while maintaining the open state of the lower ventilation path by the lower opening / closing member 14b without rotating the joint arm 8b. Then, the upper opening / closing member 14a is rotated, and the upper ventilation path can be shifted from the closed state by the upper opening / closing member 14a to the open state.

  When the operation member 6 is further rotated by a predetermined angle in the clockwise direction indicated by the arrow in FIG. 15 from the above intermediate state, the final state shown in FIGS.

FIG. 17 is a perspective view of each of the above elements viewed from the operation member side in the final state, and FIG. 18 is a perspective view of each of the above elements viewed from the opening / closing member side in the final state.

  When the operation member 6 is further rotated by a predetermined angle clockwise as indicated by an arrow in FIG. 15 from the intermediate state, the projecting edge 15 of the operation member 6 is also rotated by the same angle clockwise, and the gear portion on the outer periphery of the projecting edge 15 The gear portion 17a of the operating member 17 meshing with 15a also rotates in the direction indicated by the arrow in FIG. The operating member 17 is also rotated together with the gear portion 17a, and the operating shaft 12 provided integrally with the operating member 17 also rotates in the direction indicated by the arrow (counterclockwise) in FIG.

  Since the operating shaft 12 is located in the arcuate portion 20a of the slit 20 in the joint arm 8a in the intermediate state shown in FIG. 11, even if the operating shaft 12 moves to the position shown in FIG. It only moves along the arcuate portion 20a of the slit 20. Therefore, the joint arm 8a does not rotate during the transition from the intermediate state to the final state, and the upper opening / closing member 14a is kept open.

  On the other hand, for the joint arm 8b, as shown in FIGS. 11 and 15, the operating shaft 12 moves from the arcuate portion 11a of the slit 11 in the joint arm 8b into the linear portion 11b. In addition, the joint arm 8 b receives a force in a direction in which it is pulled away from the operation member 6 by the operating member 12. The joint arm 8b receives such a force from the operating shaft 12, and when the operating shaft 12 moves from the arc-shaped portion 11a of the slit 11 in the joint arm 8b into the linear portion 11b, the lock claw 10b of the joint arm 8b. And the engagement state with the wall part 22b of the guide groove 13b is cancelled | released. As a result, as shown in FIG. 15, the joint arm 8 b rotates in a direction away from the operation member 6. By rotating the joint arm 8b in this manner, the lower opening / closing member 14b can be rotated together with the joint arm 8b in the direction indicated by the arrow in FIG. Thereby, only a lower side ventilation path can be opened.

  In the process from the intermediate state to the final state as described above, only the joint arm 8b is rotated while maintaining the open state of the upper ventilation path by the upper opening / closing member 14a without rotating the joint arm 8a. The lower opening / closing member 14b is rotated, and the lower ventilation path can be shifted from the open state by the lower opening / closing member 14b to the closed state.

  As described above, in the vehicle air outlet unit 1 according to the present embodiment, by operating one operating member 6, a plurality of opening and closing members can be individually driven to open and close each ventilation path individually. it can.

  In addition, it is also possible to make it transfer to an initial state through an intermediate state from said final state by making the rotation direction of an operation member into a reverse direction. It is also possible to shift from the intermediate state to the initial state or the final state.
