Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a vehicle ventilation system using a window frame of a fitted window.9 (Prior Art) As a conventional vehicle ventilation system, for example, 1972-
Those described in Japanese Utility Model Publication No. 33847 and Japanese Utility Model Publication No. 47-28829 are known.

In the device described in Japanese Utility Model Application Publication No. 52-33847, a ventilation hole (opening) that connects the inside of the car with the outside of the car is opened in a pillar panel of the car body facing the outside of the car, and a ventilation hole is formed on the outer surface of the pillar panel. A finisher (grille) was attached to hide the

Further, in the device described in Japanese Utility Model Publication No. 47-28829, a ventilation hole 1 through-hole and an opening were formed in the door panel.

(Problem to be Solved by the Invention) However, in the conventional vehicle ventilation system as described above, ventilation holes are formed in the outer and inner panels of the vehicle body, such as pillar panels and door panels. As a result, there were the following problems.

■ Rigidity of the vehicle body decreases.

@ For example, in the case of a bus, etc., there are two specifications for the same car model: one with windows that can be opened and closed like sliding windows, and one with fixed windows, and the one with fixed windows must be equipped with a ventilation system. Vehicle bodies cannot be shared because ventilation holes are drilled in the vehicle body.

◎ Since the ventilation holes face the outside of the vehicle, a finisher is required to hide the holes, which increases the number of parts and installation man-hours, and also makes it difficult to create a flush surface.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, a The pillar has an outer surface facing the outside of the vehicle, a side surface of the pillar that continues from the outer surface of the pillar toward the inside of the vehicle, and a peripheral surface of the pillar that continues from the side surface of the pillar toward the window opening and faces outside the vehicle. In the vehicle window in which the window frame extends along the side edge of the window opening, the window frame is provided on the peripheral surface of the pillar with a gap between the pillar side surface and the window frame side, A window glass covering a window opening is fixed to the frame, and the outer surface of the window glass is disposed on substantially the same plane as the outer surface of the pillar, and the end surface of the glass is disposed with a gap between the side surface of the pillar and the glass side. A ventilation hole was opened in the window frame facing the side of the pillar to communicate the inside of the car with the outside of the car.

(Function) Therefore, the outer glass surface of the windshield and the outer surface of the pillar form the outer surface of the vehicle body, and negative pressure is generated on the outer surface of the vehicle body while the vehicle is running.

And, due to this negative and positive, a ventilation hole in the window frame provided between the window glass and the pillar, a gap on the window frame side between the window frame and the side of the pillar, and a gap on the glass side between the outer edge of the glass and the side of the pillar are formed. The air (positive pressure) inside the car is exhausted to the outside of the car through the passageway.

Further, the ventilation hole is arranged on the inside of the vehicle from the glass-side gap between the outer edge of the glass and the side surface of the pillar, and faces the side surface of the pillar, so that it is not visible from outside the vehicle.

Further, the outer edge of the rear frame 22 is disposed with respect to the pillar side surface 14 with a window frame side gap t1 interposed therebetween.

Note that 150 in FIG. 1 is a cover member that covers the rear end portion of the outer plate member 27.

A ventilation shutter 31 is attached to the attachment hole 25, as shown in FIG. 1.4.6.

This ventilation shutter 31 has the mounting hole 25 in an open state (
the inside of the vehicle 130 and the hollow part 30 are in communication),
It closes the opening and includes a guide member 32 that is attached to the attachment hole 25 and a slide member 33 that slides with respect to the guide member 32.

As shown in FIG. 4, the guide member 32 has a
Air holes 321 are arranged vertically on the 30 side, a guide elongated hole 322 is formed in the vertical direction beside the air hole 321, and a slide guide groove 323 for guiding the slide of the slide member 33 is formed on the back side of the air hole 321. Furthermore, a locking pawl 324 that locks into the mounting hole 25 is provided.

The slide member 33 is connected to the air hole 32 of the guide member 32.
A ventilation hole 331 whose shape matches that of 1 is formed, and the ventilation hole 33

The window glass 40 fits and covers the window opening 110, and as shown in FIG. The inner peripheral edge of the glass is disposed on the surface and the rear edge 42 of the glass is disposed through the glass side gap t2 that communicates the pillar side surface 14, the window frame side gap t1, and the vehicle exterior 120. The window frame 20 is adhesively fixed to the outside surface of the vehicle with an adhesive 141.

The ventilation hole 50 is the hollow part 30 of the rear frame 22.
This ventilation hole 5 communicates with the window frame side gap t1.
As shown in FIGS. 1 and 6, five holes are formed facing the pillar side surface 14 below the ventilation shutter 34.

In addition, each of the five ventilation holes 50 is provided with a hole from the outside 120 side of the vehicle and from the side of the hollow part 30 to the outside 120 side of the vehicle, as shown in FIG. 5.6.
A one-way valve 51 is provided to allow ventilation only to the side and to prevent rainwater etc. from entering the hollow portion 30.

This one-way valve 51 is made of a rubber sheet and has an opening/closing door 52 formed at a position covering each ventilation hole 50.

Next, the operation of the embodiment will be explained.

When ventilating the interior 130 of the vehicle, slide the slide member 33 using the operation knob 332 to align the air holes 321 and the ventilation holes 331 and open the air holes 321, thereby opening the pillar side surface 14 and the rear frame. The interior of the vehicle 130 and the exterior of the vehicle 120 are communicated through the window frame side gap 1+ between the pillar side surface 14 and the window glass 40, the glass side gap t2 between the pillar side surface 14 and the window glass 40, and the hollow portion 30.

Then, as the vehicle A runs, negative pressure is created on the outside 120 side of the window frame side gap t1 and the glass side gap t2, so that the inside 130
As shown in FIG. 6, the air hole 321 and the ventilation hole 33
1 into the hollow part 30, flows downward inside the hollow part 30, and is discharged to the outside of the vehicle 120 through the ventilation hole 5o.

At this time, the opening/closing door 52 is rotated upward by the air discharged from inside the vehicle 130, as shown in FIG.

Also, due to crosswinds, etc., the window frame side I! When the pressure in the vicinity of the JI gap t1 and the glass side gap t2 becomes higher than that in the vehicle interior 130, the opening/closing door 52 is closed by the pressure, and rainwater and wind do not enter the hollow interior 30 from the vehicle exterior 120.
Further, even if rainwater were to enter, the air hole 321 on the inside 130 side is located at a higher position than the ventilation hole 50 on the outside 120 side, so it will not enter into the inside 130 side.

Furthermore, when ventilation of the interior 130 of the vehicle is not necessary, the air hole 321 of the guide member 32 is closed by the slide member 33, so that the exterior 120 including the hollow portion 30 and the interior 130 of the vehicle
Communication with 0 is cut off.

Further, the ventilation hole 50 is located between the pillar side surface 14 and the glass rear edge 42.
is arranged closer to the vehicle interior 130 than the glass side gap t2 with the glass side gap t2,
Furthermore, since it faces the pillar side surface 14, the one-way valve 5
Regardless of the presence or absence of 1, it cannot be seen from outside the vehicle.

In addition, by slidingly adjusting the sliding member 33 of the ventilation shutter 31, the opening degree of the air hole 321 can be adjusted and the ventilation amount can be finely adjusted.

To attach the fill-in window B to the window opening 110, the vehicle interior side surface of the window frame 20 and the pillar circumferential surface 15 are adhered with the adhesive 141 as described above.

The window frame of a known sliding window (not shown) forms a glass sliding rail or groove facing the window opening, and after fitting the glass into the sliding rail or groove so that it can be opened and closed, the window frame is opened. Fit the inner side of the frame and apply adhesive 140 in the same way as the window frame 20 of window B.
It is glued to the pillar peripheral surface 15 with.

Further, in the ventilation system of the present invention, the ventilation hole 50 at the outermost side of the vehicle is located at the outer plate member 27. It is hidden behind the glass rear edge 42 and the pillar 10 and is not visible from outside the vehicle 120 or is difficult to see.

In the fitted window B, the window frame 20 serves as a spacer,
By creating a flush surface in which the outer surface of the vehicle body, such as the outer surface of the glass 41 and the outer surface of the pillar 13, are substantially the same surface, aerodynamic drag is reduced and wind noise is reduced.

In the ventilation system, since the ventilation hole 50 is covered by the opening/closing door 52 of the one-way valve 51, rainwater, dust, etc. from the outside of the vehicle 120 are prevented from entering the hollow part 30 and the inside of the vehicle 130 through the ventilation hole 50.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in the embodiment, ventilation is provided in one direction from the inside of the vehicle to the outside of the vehicle, but it may be possible to provide mutual ventilation, or it is also possible to provide ventilation in both directions.

Further, although the device is provided on the rear side of the window in the embodiment, it may be provided on the front side.

(Effects of the Invention) As explained above, in the vehicle ventilation system of the present invention, since the ventilation holes are formed in the window frame rather than in the vehicle body panel, the air inside the vehicle can be ventilated without reducing the rigidity of the vehicle body. be able to. In addition, with sliding windows, ventilation is possible by opening the window glass, and with closed-in windows, ventilation can be achieved by using the ventilation system of the present invention. Since it is possible to use a common vehicle body, it is possible to obtain the effect that a common vehicle body can be used.

In addition, since the ventilation holes are not visible from outside the vehicle, there is no need for a finisher to hide the ventilation holes, which saves the time and effort of installing a finisher, and makes it easier to create a flush surface.
The effect is that the appearance can be improved.
