The rotation arm is rotated by the forward movement of the torsion spring contact side, and closes the adjustment plate in the ventilator via the interlocking member.

When storing the ashtray after use, the contact side of the torsion spring is pushed back against the biasing force. The rotating arm is rotated by the backward movement of the torsion spring contact side, and opens the adjustment plate in the ventilator via the interlocking member.

The contact side of the torsion spring has a spring action, which acts to relieve unreasonable load stress when inserting and removing the ashtray.

(Example) Next, the first example of the present invention will be described in Figures 1 to 5.
This will be explained based on the diagram. 1 to 5, a ventilator outlet 6 is provided in the center of an instrument panel 1 of an automobile, in this example the left side of the instrument panel 2, and a pull-out ashtray is provided below the outlet 6. 3 is placed. The bulging parts 3C of the ashtray 3 at the upper ends of both sides of the ashtray 3 are slidably locked to the locking parts 4A of the support plate 4 fixed horizontally within the instrument panel 1, and can be taken in and out from one side of the instrument panel. It is being done. Note that a finger hook 3B for pulling out the ashtray 3 is provided on the front end (end on the vehicle interior side) 3A of the ashtray 3, and a retainer (not shown) for the ashtray 3 is formed on the support plate 4. has been done. An outlet 6 of the ventilator 5 is connected to a duct 7 so that air for air conditioning can be blown out. Note that 6A is a guide plate that changes the direction of the blown air. The duct 7 near the outlet 6 has a rectangular cross section, and an adjustment plate 8 for adjusting the air flow rate is installed inside this part of the duct 7.
They are arranged perpendicular to the longitudinal direction. Adjustment plate 8
Both ends 9A and 9B of a support shaft 9 fixed in the longitudinal direction at the center thereof protrude outside the side walls 7A and 7B of the duct 7 and are rotatably supported, and one end of the support shaft 9 outside the side wall 7A An interlocking member 10 for rotating the support shaft 9, that is, the adjustment plate 8, is fixed to the 9A side.
On the other hand, a bracket 11 that pivotally supports a rotating arm 13 and a torsion spring 15 is attached to the outer surface of the duct 7 below the adjustment plate 8. The rotating arm 13 has an axial hole in the center, a long hole 13B in the upper end, and a locking groove 13D in the bent piece 13C at the lower end. The upper end is pivotally connected to the lower end of the interlocking member 10 via the pin 14 in the elongated hole 13B. The torsion spring 15 is an annularly wound spring wire end 15.

It extends downward so that it can be biased toward the front side. However, the urging force of the torsion spring 15 is not strong enough to push the ashtray 3 forward. The adjustment plate 8 is arranged so that the ashtray 3 is connected to the instrument panel 1.
The lower end of the torsion spring 15 is set so that when the ashtray 3 is fully stored in the interior, the duct 7 is opened horizontally, and when the ashtray 3 is fully pulled out and ready for use, the duct 7 is closed vertically. The length of the side end 15A and the pivot position between the upper end of the rotating arm 13 and the interlocking member 10 are set in advance.

Therefore, when ventilation air is flowing in the duct 7 and air is being blown out from the outlet 6, when the ashtray 3 is pulled out from the instrument panel 1 for smoking, the ashtray 3 must be pulled out. As it moves, torsion spring 1
The lower end 15A of the bracket 11 is moved forward by a set amount (the amount of movement of the ashtray), and the rotating arm 13 is rotated in the direction of arrow P in FIG. 5 about the support shaft 12 of the bracket 11. Therefore, the interlocking member 10 pivotally attached to the upper end of the rotating arm 13 is rotated about the support shaft 9 in the direction of the arrow P shown in the figure, and the adjustment plate 8 in the duct is moved in the direction of the arrow Q shown in FIG. Since the duct 7 is rotated approximately 90 degrees and held vertically, the flow rate of air inside the duct 7 is almost blocked by the adjustment plate 8, and the amount of air blown out from the outlet 6 is reduced, which is convenient for smoking.

When the ashtray 3 is housed in the instrument panel 1, the above-described operation is performed in the reverse order, the adjustment plate 8 is returned to the horizontal position, and a predetermined amount of air is blown out from the air outlet 6.

Next, a second embodiment of the present invention will be described based on FIGS. 6 to 8. Note that the ventilator 5 in this second embodiment has an air outlet 6 on the upper side of the pull-out ashtray 3 in the center of the instrument panel 1 of the automobile, as in the case of the first embodiment described above. (See Figure 1). The ashtray 3 has bulging portions 3C at the upper ends of both sides of the ashtray 3 slidably locked in locking portions 4A of a support plate 4 fixed horizontally within the instrument panel 1, and can be inserted and removed from the instrument panel 1 side. is made possible.

3 has an inverted L-shape, the shaft hole in the center is inserted into the support shaft 22 of the bracket 21, and the bent piece 23C at the lower end is provided with a locking groove 23D. The torsion spring 25 has an annularly wound end 25
The A and 25B sides are always expanded,
The annular portion is inserted into the support shaft 22 of the bracket 21. The upper end 25B side of the torsion spring 25 is locked and fixed to the upper surface of the bracket 21, the lower end 25A side is locked in the locking groove 23D of the bent piece 23C of the rotating arm 23, and the lower end 25A side is extended. Abuts against the rear end 3D of the put-out ashtray 3,
Moreover, it extends downward so that the rear end portion 3D can be biased toward the front side of the ashtray 3. On the other hand, an adjustment plate 28 is installed in the duct 7 near the outlet 6.
It is arranged perpendicularly to the longitudinal direction of the duct, and is rotatably supported by a support shaft 29 on both side walls 7A and 7B of the duct. An interlocking member 30 is attached to the short side end 28A of the adjustment plate 28, and the interlocking member 30 projects outward from the through hole 7C on the lower surface of the duct 7. upper end 2
Connected to 3B. That is, the interlocking member 30
The upper end 30A bent into an L shape is the adjustment plate 28.
The lower end 30B is bent and pivotally supported by the upper end 23B of the rotating arm 23. The adjustment plate 28 is turned sideways to open the duct 7 when the ashtray 3 is fully accommodated in the instrument panel 1, and closes the duct 7 when the ashtray 3 is fully pulled out and ready for use. Torsion spring 2 so that it is oriented vertically
The length of the lower end 25A of the rotating arm 23 and the pivoting position between the upper end of the rotating arm 23 and the interlocking member 30 are set in advance. Therefore, when the ashtray 3 is pulled out and used while air is being blown out from the air outlet 6, the lower end 25A side of the torsion spring 25 moves forward by a set amount as the ashtray 3 is pulled out, and the bracket 21 is moved forward by a set amount. In order to rotate the rotating arm 23 in the direction of the arrow R shown in FIG. 8 with the support shaft 22 as the rotation center, and to pull the interlocking member 30 pivotally attached to the upper end 23B of the rotating arm 23 downward by a set amount, The adjusting plate 28 is rotated approximately 90 degrees in the direction of arrow S shown in FIG. 8 and is held in a vertical position. Therefore, the flow rate of air in the duct 7 is almost blocked by the adjustment plate 28, and the amount of air from the outlet is reduced, which is convenient for smoking. Note that when storing the ashtray 3 in the instrument panel 1, the adjustment plate 28 is returned to the horizontal position in the reverse order described above.

(Effects of the invention) By using the invention as the problem-solving means, the intended problem is solved by the action described above. That is, according to the present invention, it is of course a simple structure of mechanical means, and when the ashtray is pulled out, the adjustment plate in the ventilator closes, and the amount of air blown from the outlet is weakened. This is convenient because cigarette ash does not scatter, and if the ashtray is stored in the instrument panel, the adjustment plate in the ventilator opens and a predetermined amount of air is blown out from the outlet. In addition, since the present invention adjusts the amount of air blown from the outlet when using the ashtray, there is no problem even if the outlet and the ashtray are placed close to each other. The setting position is not limited to a position away from the air outlet, and the ashtray can be easily set on the instrument panel.

In addition, in the present invention, the contact side of one end of the torsion spring extends through the one end side of the rotating arm, and simply contacts the ashtray in a biased state when stored, and the contact side and the ashtray are connected. Because of the structure that does not allow the ashtray to be inserted or removed, the ashtray can be taken in and taken out through contact on the contact side of the torsion spring, and even if an excessive force is applied to take the ashtray in or out, the unreasonable load stress will be absorbed by the spring force on the contact side. It has the advantage of not damaging the equipment.
