Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in the mounting structure of a ventilator grill for an automobile.

Prior Art Conventionally, as shown in FIGS. 1 and 2, an opening 2 is formed in an instrument panel 1, and a sandwiched plate part 4 is formed in a case 3 for forming a ventilator grille extending in the direction of air blowing. Open the ventilator grille configuration case 3 from the direction of arrow A 2.
The clamped plate part 4 is inserted between the clamping plate part 5 formed on the instrument panel 1 and the pad 6 covering the instrument panel 1, and the clamped plate part 4 is clamped. A mounting structure for an automobile ventilator grill is known in which a ventilator grille 7 is sandwiched between a plate portion 5 and a pad 6, and is mounted on an instrument panel 1 and connected to a ventilation duct (not shown). (Refer to the mounting structure in Japanese Utility Model Application Publication No. 57-130713). In addition, in FIG. 1, 8 indicates a vertical louver, 9 indicates a vertical louver operating member, and 10 indicates a horizontal louver.

By the way, in this conventional automobile ventilator grille mounting structure, a lever mechanism 12 serving as a shutter valve mechanism for opening and closing a shutter valve 11 for adjusting air volume is mounted on the outside of a case 3 for constructing a ventilator grille, as shown in FIG. arranged,
When inserting the ventilator grille forming case 3 into the opening 2, the lever mechanism 12 is guided into the opening 2 while facing the holding plate part 5 as the opening surrounding wall, so that the ventilator grille forming case 3 and the opening are guided. Since there is not enough space between the ventilator grille and the surrounding wall, the ventilator grille configuration case 3 is
Depending on how the case 3 for constructing the ventilator grille is inserted into the opening 2, a part of the lever mechanism 12 may come into contact with the clamping plate 5, which is the peripheral wall of the opening, from the insertion direction. However, there is a problem in that the lever mechanism 12 as a shutter valve mechanism may break.

OBJECT OF THE INVENTION The present invention has been made in view of the problems of the prior art described above, and an object of the present invention is to insert a case for configuring a ventilator grille into an opening formed in an instrument panel. An object of the present invention is to provide a mounting structure for a ventilator grill for an automobile, which can reliably prevent breakage of a shutter valve mechanism when the ventilator grill is mounted on an instrument panel.

The ventilator grill configuration case 20 has a side wall 22, a top wall 23, and a bottom wall 24, and the side wall 22 has a clamped portion at the rear end in the insertion direction of the ventilator grill 13. A plate portion 25 is formed, and a clamped plate portion 26 is formed on the upper wall portion 23 and the bottom wall portion 24 at their rear ends in the insertion direction. The clamped plate parts 25 and 26 are configured to extend along the periphery of the opening, and constitute an outer frame of the case.
The instrument panel 15 is formed with a clamping plate part 27 as an opening peripheral wall, and the clamped plate parts 25 and 26 are inserted between the clamping plate part 27 and the pad 14 so that the clamping plate part 27 and the pad 14 can be connected to each other. FIG. 5 shows a state in which the clamped plate part 26 is clamped by the clamping plate part 27 and the pad 14, and the clamped plate part 26 is clamped by the clamped plate part 27 and pad 14. The parts 25 and 26 are configured to extend in the insertion direction, and the forward part in the extending direction is connected to the clamping plate part 27.
The tip is tapered to facilitate entry between the pad and the pad 14. The ventilator grill configuration case 20 is provided with a shutter valve for adjusting the air volume, a horizontal louver, and a vertical louver. In FIG. 5, 28 is the pivot shaft of the horizontal louver, and in FIG. 6, 29 is the vertical louver. 30 indicates a shut valve.

The shut valve 30 is opened and closed by a shut valve mechanism 31 for opening and closing operations.
Here, this shut valve mechanism 31 is the sixth
As shown in FIG. 7, it is disposed on the bottom wall portion 24. The shutter valve mechanism 31 here has a lever configuration, and in FIGS. 6 and 7, reference numerals 32 and 33 indicate lever component plates, and 34 indicates a rotary operating member. As shown in FIG. 6, the bottom wall portion 24 is provided with a pair of guide plate portions 35 spaced apart in the opposite direction of the side wall portions 22, 22. The front end in the insertion direction is connected by a connecting plate part 36 extending in a direction crossing between the side walls 22, 22, and the rear end in the insertion direction is connected to the case outer frame. connected to. The connecting plate portion 36 is connected to the case 20 for configuring the ventilator grille.
When inserting into the instrument panel 15,
It comes into contact with the sealing rubber 19 to position the ventilator grille forming case 20 in the insertion direction.

The space surrounded by the guide plate portion 31 and the connecting plate portion 36 is a space for arranging the shut valve mechanism, and the shut valve mechanism 31 is disposed therein. The connecting plate part 36 and the guide plate part 35 cooperate to constitute a reinforcing frame part of the case 20 for constructing the ventilator grille.The case 20 for constructing the ventilator grille is made of synthetic resin. The plate portion 36 and the guide plate portion 35 ensure the heat resistance of the case outer frame when the air blowing temperature is high. Guide plate part 35
When inserting the ventilator grill configuration case 20 into the opening 18, the lower surface 37 of the case 20 is inserted into the holding plate portion 2.
7, the lower surface 37 has a curved surface 38 at its forward end in the insertion direction, and when inserting the ventilator grill configuration case 20, the curved surface 38 first comes into sliding contact with the holding plate portion 27, Thereafter, the plane portion 39 comes into sliding contact with the holding plate portion 27, and the ventilator grille forming case 20 is connected to the shutter valve mechanism 3 by this guide plate portion 37.
1 and the holding plate part 27 while maintaining the gap between the opening 18
This is what you will be guided by.

Effects of the Invention As explained above, the present invention extends in the insertion direction of the case for composing a ventilator grille, and is in sliding contact with the opening peripheral wall of the instrument panel, so that the opening peripheral wall and the shuttle valve mechanism are connected to each other. Since the guide plate part is formed to guide the ventilator grille forming case to the opening while maintaining the interval, it is possible to reliably prevent the shutter valve mechanism from breaking when the ventilator grille is mounted on the instrument panel.
