Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a duct drafter for a vehicle such as an automobile.

2. Description of the Related Art A conventional duct drafter for a vehicle is actually developed in Sho 60-1222.
As described in Japanese Patent Publication No. 09 and shown in FIG.
A duct drafter 11 for communicating the interior of the automobile 13 with the interior of the trunk room is provided, and a duct drafter 12 for communicating the interior of the trunk room with the exterior of the automobile is provided. One example of this duct drafter is Shokoku Sho 58-
As described in Japanese Patent Publication No. 9775 and illustrated in FIG.
The flap 14 made of a rubber material is attached to one side of the retainer 15, and the retainer 15 is attached to the drafter case 1.
It is assembled in 6.

Problems to be Solved by the Invention In this conventional vehicle duct drafter, since the flap 14 is made of a rubber material, the flap 14 does not close in a predetermined manner due to deterioration of the rubber material of the flap with time. When the car was washed, it was half-open, and there was the drawback that water drops would penetrate into the car from the half-open flap.

The purpose of this invention is to eliminate the above-mentioned drawbacks of conventional duct drafters for vehicles, to prevent water droplets from entering the interior of the vehicle during car washing, and to smoothly discharge slightly pressurized air inside the vehicle to the outside of the vehicle. It is what

The vehicle duct drafter of the present invention has a drafter case that opens at the end face of the door installed in the interior space of the door, and a retainer rotatably installed in the drafter case serves as a door lock button. By linking with a link mechanism, the retainer was held in a state close to vertical or in a state in which the upper part was rotated from the vertical direction to the inner space side of the door in conjunction with the opening / closing operation of the door lock, and a flap was attached to the exterior of the retainer. It is a thing.

The vehicle duct drafter of the present invention has a flap attached to the outside of the retainer that rotates in conjunction with the door lock button, so that when the door is locked, the flap is easy to move due to the pressure difference between the interior and exterior of the vehicle. Since the air can be opened smoothly, air can be discharged smoothly, and when the door is unlocked and the car is washed, the flap rotates a certain angle from the vertical direction and is inclined more horizontally than when the door was locked, so the flap Due to the self-gravity of the flap, the flap is securely closed and the water drops of the car wash are reliably prevented from entering the interior of the car.

Embodiment Next, one embodiment in which a vehicle duct drafter of the present invention is illustrated will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the upper and lower door lock buttons 1 are connected to one end of a lever 4 in a drafter case 3 via a link 2. A retainer 6 is connected to the other end of the lever 4 via a shaft 5.

The retainer 6 has its upper portion rotated to the door inner space side (left side in the drawing) and its lower portion outside the vehicle (right side in the drawing).
It is installed in the drafter case 3 so that it can rotate.
A flap 7 is attached to the outside of the retainer 6 on the vehicle side.

In the automobile duct drafter of this embodiment, when the automobile is running, the door lock button 1 is pushed down as shown in FIGS. 1 and 2, the lever 4 and the retainer 6 are rotated through the link 2, and the flap 7 is removed. Similar to the retainer 6, the flap 7 communicates with a ventilation opening 9 provided inside a door 8 of an automobile at an angle close to a vertical angle (inclined by about 10 degrees in the drawing) counterclockwise from the vertical direction. The drafter case 3 is easily opened by slightly pressurized air inside the vehicle, and the slightly pressurized air is smoothly discharged to the outside of the vehicle through the gap between the door 8 and the main body.

When the car is washed, the door lock button 1 is pushed up, and when the lock is removed, the lever 4 and the retainer 6 are connected via the link 2.
The flap 7 attached to the retainer 6 by rotating is rotated about 20 degrees in the horizontal direction from an angle close to vertical as in the case of the retainer 6 and rotated about 30 degrees counterclockwise from the vertical as shown in FIG. The flap 7 is surely closed due to the gravity of the flap itself.

Although the retainer 6 and the flap 7 are tilted at an angle close to vertical when the automobile is running in this embodiment, the retainer and the flap 7 may be provided vertically.

Effect of the Invention The vehicle duct drafter of the present invention has a drafter case that opens at the end surface of the door installed in the interior space of the door, and a retainer rotatably mounted in the drafter case is connected by a door lock button and a link mechanism. , The door was locked because the retainer was held in a state close to vertical or the upper part was rotated from the vertical direction to the inner space side of the door in conjunction with the opening / closing operation of the door lock, and the flap was attached to the vehicle outer side of this retainer. At times, the flap can be easily opened due to the pressure difference between the interior and exterior of the vehicle at an angle close to vertical, so that the air can be smoothly discharged to the outside of the vehicle, and when the door is removed and the car is washed, the flap and the retainer are attached vertically. When the flap is placed on the retainer, it is tilted by rotating a predetermined angle from the direction Therefore, even if the flap is deteriorated to some extent with time, the flap itself is surely closed by the gravity of the flap itself, and it is possible to reliably prevent the water droplets of the car wash from entering the vehicle.
