Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a ventilation device that is attached to the windows of various automobiles such as passenger cars and trucks.

[Conventional technology]

If you smoke inside a car, you need to open the side windows to ventilate the smoke. There is also a vehicle that uses a fan to exhaust the air inside the vehicle to the outside of the vehicle, but it is extremely expensive.

[Problem that the invention aims to solve]

The front edge of the front door window next to the driver's seat in a passenger car is sloped diagonally backwards, so when the window glass is lowered slightly, the front edge of the window glass and the front edge of the window frame are In some cases, a space is created between them, from which air can blow into the car, preventing smoke from escaping from inside the car. Therefore, the purpose of this invention is to use the principle of a ventilly tube to quickly exhaust cigarette smoke from inside a car by installing the window glass in a slightly lowered position.

[Means for solving problems]

In order to solve the above problems, this invention provides a board that is removably attached between the upper edge of the automobile window frame and the slightly lowered upper edge of the window glass, and this board has a long ventilation hole in the front and back direction. In an automobile ventilation system, the airflow guide plate is provided with a plurality of airflow guide plates on the outside of the board to deflect the airflow flowing along the side of the car diagonally outward and rearward. is provided with an opening having a shutter that can be opened and closed over the entire length, and the outer surface of the board located at the bottom of the vent is provided with an outward facing plate that is inclined diagonally upward to the outside so that air flows upward from the side surface of the vehicle body. Airflow is deflected outward by an upstream outward facing plate.

[Effect]

The ventilation device of the present invention has the above-mentioned configuration, and when this device is attached to an automobile and the vehicle is driven, the airflow flowing from the front of the automobile along the side surfaces flows diagonally outward and rearward by each airflow guiding plate.

When such an airflow occurs, the air pressure in the vicinity of the airflow guide plate decreases, and the air inside the car is sucked out through the vents provided in the board, similar to a ventilator tube, and the air flows into the cabin. Cigarette smoke, etc., is immediately exhausted outside. Additionally, the airflow guide plate alone may not be able to prevent the hot summer airflow or the cold airflow in the winter from flowing into the interior of the vehicle, which rolls up as the car travels and rises from below the car. case,
Since there is an outward facing plate on the outside of the lower part of the vent, the above-mentioned airflow from below is prevented from flowing into the vehicle interior.

〔Example〕

In FIGS. 1 to 6, reference numeral 1 denotes a board made of hard plastic or the like, the upper edge of which fits into a groove 3 at the top of a window frame 2 of a front door of an automobile.
A groove 5 into which the upper edge of the lowered window glass 4 fits is provided in the lower part. In the figure, the upper and lower edges of the board 1 are shown as straight lines for convenience of drawing, but if the upper edge of the window frame 2 is to be attached to a gently curved upper edge, the shape should be adapted to this.

The board 1 also has ventilation holes 6 and 7 that are long in the front and back direction.
are provided at the front and rear, and a ventilation box 8 extending almost the entire length is provided at the upper part of the board 1 on the inside of the vehicle.

This ventilation box 8 has a front wall 9 and a rear wall 1 as shown in FIG.
0 and an intermediate wall 11, and the inside of the vehicle has a
As shown in the figure, it has a downward wall 12, a lower opening between the front wall 9 and the middle wall 11, and the middle wall 11 and the rear wall 10.
Shutters 13 and 14 that can be opened and closed are provided in the opening between them.

The shutters 13 and 14 are rotatably attached to the front wall 9, the rear wall 10, and the intermediate wall 11 by shafts 15, respectively.

Furthermore, knobs 16 and 17 are provided at the front ends of the shutters 13 and 14, respectively, and the shutters 14 at the rear are provided with knobs 16 and 17, respectively.
A plurality of ventilation holes 18 are provided.

At the bottom of the board 1 on the outside of the vehicle, near the front, there is an outward facing frame 2.
0 is provided, and this frame 20 is provided with a long window 21 in the front and rear direction. Further, a plurality of airflow guiding plates 22 are provided at appropriate intervals from the lower surface to the outer upper part of the frame 20, and each of the guiding plates 22 is
As shown in the figure, it is horizontally inclined so that the outer end faces diagonally backward.

The outward facing frame 20 is slightly inclined upward as shown in FIG. 6, and is further extended rearward to form a wide outward facing plate 23 as shown in FIGS. 1 and 4, reaching near the rear end of the board 1. Moreover, as shown in FIG. 7, this outward facing plate 23 is inclined obliquely upward.

A wider eaves plate 25 is provided above the outward facing plate 23, and is fixed to the substrate 1 below the vent hole 7. This eaves plate 25 is inclined slightly downward as shown in FIG. 7, and has elongated holes 26 formed in the front and back directions on the board side, and the rear end of each elongated hole 26 is shown in FIG. As shown in FIG. 5, an airflow guiding plate 27 is provided with a forward downward slope.

Further, a plurality of airflow guiding plates 28 are fixed at appropriate intervals from the lower surface of the outward facing plate 23 to the upper outer side. As shown in FIG. 4, this guide plate 28 is also inclined obliquely rearward like the guide plate 22, but is slightly larger than the front guide plate 22.

Reference numeral 30 denotes an airflow guide plate fixed on the rear end of the outward frame 20 between the front and rear ventilation holes 6 and 7. As shown in FIG. 1, the guide plate 30 has a front end fixed to the base plate 1 and a rear end fixed to the front end of the eaves plate 25. In addition, the outer frame 2 at the bottom of the guide plate 30
A triangular transparent window 31 is provided at the rear end of the vehicle.

8 and 9 is a windshield plate that fills the gap created between the front edge of the window glass 4 and the front part of the window frame 2 when the window glass 4 is lowered, so as not to impair visibility.
It is made of a highly transparent material such as transparent plastic, and its front edge fits into the groove 3 of the window frame 2, and its rear edge has a groove 36 into which the front edge of the window glass 4 fits.

Figure 9 shows this invention installed on the window frame 2 of the front door on the right side of the driver's seat of an automobile.

That is, the rear end of the board 1 fits into the groove 3 at the rear of the window frame 2, and the upper edge of the board 1 fits into the groove 3 at the top of the window frame 2.
By fitting the upper edge of the window glass 4 into the groove 5 at the bottom of the substrate 1, the movement of the substrate 1 in the vertical direction and in the inward/outward direction is stopped.

Further, the upper rear part of the wind shielding plate 35 is in contact with the front part of the board 1, and the front edge of the wind shielding plate 35 is in contact with the groove in the front part of the window frame 2.
Since the front edge of the window glass 4 fits into the rear groove 36, the base plate 1 and the wind shield plate 35 are fixed to the window frame 2 so as not to move.

When a car is driven with the ventilation device of this invention installed as described above, an air current is generated accordingly.

This airflow flows along the windowpane 4, and above the windowpane 4, the airflow is guided outward by the multiple airflow guide plates 22, 28 of the device of this invention.

Furthermore, as shown in FIG. 7, an eaves plate 25 and an outward facing plate 23 are provided above and below in the lower part near the rear of the board 1, so that the front and rear and outer sides of the space between them are open. Therefore, the airflow passes between the plates 25 and 23, and during this time, a part of the airflow is directed diagonally upward by the guide plate 27 in FIG.

As mentioned above, since all the air passing through the outer part of the substrate 1 is guided outward, the air pressure in this part becomes lower than the atmospheric pressure.

On the other hand, inside the car, when the shutters 13 and 14 are closed as shown in Figs. Air is taken into the box 8 and exhausted from the vents 6 and 7.

Next, when the shutters 13 and 14 are opened, the air in the room flows through the ventilation box 8 and the ventilation holes 6 and 7, and is quickly exhausted to the outside. Therefore, if the vehicle is running with the shutters 13 and 14 closed during cooling or heating, a small amount of ventilation can be carried out without impairing the cooling or heating effect, and if the shutters are opened at a suitable time, the air inside the vehicle can be replaced.
In addition, hot air in the summer and cold air in the winter that roll up and rise from below the car as the car travels are deflected outward and upward by the outward facing plate 23, so these air flows flow into the car through the vents. There's nothing to do. If your car is equipped with an air conditioner, turning on the ventilation switch will further increase the ventilation effect.

〔effect〕

According to the present invention, as described above, by lowering the window glass of an automobile and installing it in the space created between the window frame and the window glass, the air inside the car can be quickly exhausted to the outside of the car while the car is running. That is, the plurality of airflow guide plates on the outside of the substrate attached between the window frame and the window glass can deflect the airflow on the side of the vehicle body generated as the vehicle travels outward and rearward. Therefore, the air pressure near the outside of the board is low, and the air inside the car quickly flows out of the car by opening the shutter of the ventilation box inside the car, so even if you smoke inside the car, the smoke is quickly exhausted outside the car. and does not cause discomfort to fellow passengers.

Particularly in the case of this invention, since the outer surface of the board located at the bottom of the vent is provided with an outwardly facing plate that is inclined diagonally upward, the hot airflow in the summer that is kicked up as the car runs is prevented. Cold airflow during the winter season is deflected outward by the outward facing plate, and therefore there is no possibility that hot air during the summer season or cold air during the winter season will flow into the vehicle interior.

In addition, even when driving with the shutters fully open, no air is blown into the interior of the car, so you can drive comfortably with the shutters fully open even in the rain. When parking, leave the shutters fully open to allow natural ventilation inside the car and prevent the temperature inside the car from rising abnormally.

Furthermore, if you close the shutters during cooling or heating, there is no risk of large amounts of cold or warm air escaping outside the vehicle.
This has the effect of keeping the air inside the car fresh by providing some ventilation.
