Description

 Description Automotive visor Technical field

 The present invention relates to a vehicular side visor mounted as a sunshade above a window opening of a vehicle, wherein air inside the vehicle is discharged from a suction port formed therein by utilizing a negative pressure generated during vehicle traveling. The present invention relates to an automotive side visor that can be used. Background art

 Conventionally, an exhaust function has been added to an automobile side visor, which is installed as a sunshade at the top of the window of an automobile to exhaust and ventilate the interior of the vehicle, such as by discharging tobacco smoke outside the vehicle. Things have been proposed.

 In this automobile side visor, a mounting portion is formed continuously from the upper edge to the front and rear sides, and the visor main body is formed by bulging out of the mounting portion to the outside. The part had a suction port.

 Therefore, when the vehicle is running, if the glass window is slightly lowered to open the upper portion of the window opening, the air in the vehicle compartment can be discharged to the outside of the vehicle compartment through the suction port due to the negative pressure during the vehicle traveling. As described above, the use of the automobile side visor allows the air in the passenger compartment to be discharged to the outside of the passenger compartment without using any power.

However, such a conventional automobile side pizer simply has a suction port opened in the body of the pizer, and the suction port is not provided. No measures have been taken to reduce wind noise caused by wind engulfed in the vehicle, or to prevent rainwater from entering rainwater through the exhaust port.

 Also, in the conventional automobile side visor, since a gap remains between the lower edge of the visor body and the glass window, the gap is passed through the gap to the inner space of the visor body. Running wind enters. Therefore, the traveling wind enters the passenger compartment, which opposes the exhaust of air from the passenger compartment, and there is a problem that the exhaust efficiency is reduced.

 The present invention has been made in order to solve the above-mentioned conventional problems, and provides an automotive side visor that prevents wind noise and rainwater from entering and that can efficiently exhaust air. Is an issue. Disclosure of the invention

 In order to solve the above-mentioned problems, an automotive side visor according to the present invention (claim 1)

 An automotive side visor mounted above the window opening of the vehicle body,

 The mounting portion is formed continuously from the upper edge to the front and rear edges, and bulges outward from the mounting portion to form a visor body,

 An elastic seal piece that comes into contact with the window glass is protruded from the lower edge of the inner surface of the body of the paiser to form an internal space surrounded by the mounting portion and the porcelain seal piece.

 A tunnel-shaped ventilation path is formed in the visor body from the front air intake to the rear air exhaust,

A suction port communicating with the internal space is formed on the inner wall surface of the ventilation path. Configuration.

 In this case, the suction port is formed above the bottom wall surface of the ventilation path (Claim 2), and the outward and rearwardly protruding fins are provided at the front edge of the suction port (Claim 2). There is claim 3).

 When air is exhausted from the passenger compartment using the automotive side visor of the present invention (claim 1), the glass window is slightly lowered to open the upper part of the window opening when the vehicle is running. .

 When a vehicle is running, a negative pressure is generated along the vehicle body due to the wind flowing along the vehicle body.By using this negative pressure, all the power in the vehicle interior air can be used through the suction port. Can be discharged to the outside of the passenger compartment.

 That is, in the automotive side visor of the present invention, the traveling wind when the vehicle is traveling flows into the tunnel-shaped ventilation path from the air intake port and is exhausted from the rear air exhaust port. At this time, the traveling wind flowing in the ventilation path draws the air in the vehicle compartment from the suction port into the ventilation path, and is discharged from the air exhaust port together with the traveling wind.

 In this case, since the elastic sealing piece that comes into contact with the window glass protrudes from the lower edge of the inner surface, the gap between the lower edge of the main body of the paiser and the window glass is closed.

Therefore, it is possible to prevent the traveling wind from entering the internal space (the space surrounded by the window frame mounting portion and the elastic seal piece) of the main body of the pizer through the gap with the window glass. As a result, the internal space of the main body of the piza becomes an integrated space with the vehicle interior through the window opening, so that it is in the same state as if a suction port was directly formed in the vehicle interior, and exhaust was efficiently exhausted. Can be. In addition, a tunnel-shaped air passage is formed in the main body of the pazer, and a suction port is formed on the inner wall surface of the air passage. It is covered by the outer wall.

 Therefore, the outer wall surface of the ventilation path functions as a cover for the suction port against rainwater blown to the side surface of the vehicle body, and it is possible to prevent rainwater from entering.

 In addition, since the air outlet is covered with the outer wall surface of the ventilation path, the air outlet is not directly exposed to the outside of the vehicle, so that generation of wind noise due to the air outlet can be prevented.

 In addition, during rainfall, rainwater enters the ventilation path from the air intake and accumulates at the bottom of the ventilation path. In this case, the suction port is formed above the bottom wall of the ventilation path. By doing so (claim 2), it is possible to prevent rainwater from entering the passenger compartment from the bottom of the ventilation path through the suction port. Rainwater collected at the bottom of the ventilation path flows on the bottom wall of the ventilation path due to the traveling wind and is discharged from the air exhaust port.

 Also, if a fin outwardly and rearwardly protrudes from the front edge of the suction port (claim 3), a negative pressure will be generated behind the fin and the air inside the vehicle compartment will be efficiently exhausted. Can be. BRIEF DESCRIPTION OF THE FIGURES

FIG. BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the present invention. FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, FIG. 3 is a cross-sectional view taken along line B-B of FIG. 1, and FIG. 4 is a cross-sectional view of an automobile side visor according to an embodiment of the present invention. FIG. 1 is a side view showing an automobile in a state where one is attached to a vehicle body.

 As shown in FIGS. 3 and 4, the automotive side visor 12 is mounted on a window opening 10 provided in a door 1 (vehicle body) of the vehicle, and is made of synthetic resin or stainless steel. It is formed of metal such as aluminum.

 The side visor 12 has a mounting portion 20 to the window frame 11 forming the window opening 10 continuously from the upper edge 20a to the front edge 20b and the rear edge 20c. While being formed, the visor main body 21 is formed so as to bulge out of the mounting portion 20 to the outside.

 At the lower edge of the inner surface of the visor main body 21, a flexible sealing piece 22 abutting on the window glass 12 is projected, and is surrounded by the elastic sealing piece 2 2 and the mounting portion 20. An internal space S is formed inside the paiser body 21.

 In addition, the above-mentioned natural sealing piece 22 is detachably fitted into a mounting groove 23 formed along a lower edge of the inner surface of the paiser main body 21, and a distal end portion thereof is an outer surface of the window glass 12. The visor body 21 is in close contact with the window glass 12 with an elastic force so as to close the gap between the lower edge of the visor body 21 and the window glass 12.

 Further, a tunnel-shaped ventilation path 3 is formed in the visor body 21 from the front air intake port 30 to the rear air exhaust port 31, and the inner wall surface 3 a of the ventilation path 3 A suction port 32 communicating with the internal space S is formed.

In this case, the three suction ports 32 are provided in parallel with three grill plates 3 2a welded to the inner wall surface 3a, and each of the suction ports 32 is vertically long with the upper side facing backward. An opening is formed obliquely, and a fin 32 b is provided on the front edge so as to project outward and rearward.

 Further, the suction port 32 is formed above the bottom wall surface 3b of the ventilation path 3, whereby the bottom of the ventilation path 3 is formed in a gutter shape.

 The aforementioned vehicle side visor 12 has the mounting portion 20 attached to the window frame 11 by other fixing means or the like, and is originally used as a sunshade.

 In order to exhaust the air in the passenger compartment using the side visor 12, the glass window 12 was slightly lowered as shown in FIG. 3 to open the upper part of the window opening 10 while the vehicle was running. State.

 Therefore, when the vehicle is running, a negative pressure is generated along the vehicle body due to the wind flowing along the vehicle body, and this negative pressure allows the air in the vehicle compartment to be completely removed from the air in the vehicle compartment through the suction port 32. It can be discharged outside the cabin.

 That is, the traveling wind when the vehicle is traveling flows into the ventilation path 3 from the air intake port 30 and is exhausted from the rear air exhaust port 31. At this time, the vehicle interior air is drawn into the ventilation path 3 from the suction port 32 by the traveling wind flowing through the ventilation path 3, and is discharged from the air exhaust port 31 together with the traveling wind.

 In this case, since the elastic seal piece 22 that comes into contact with the window glass 12 protrudes from the lower edge of the inner surface of the main body 21 of the paiser 21, the lower green of the visor main body 2 1 and the window glass 1 2 Is closed.

Therefore, it is possible to prevent the traveling wind from entering the inner space S of the visor body 21 through the gap. That is, since the inner space S of the visor main body 21 becomes an integrated space with the vehicle interior through the window opening 10, the state becomes the same as when the suction port 32 is directly formed in the vehicle interior. Exhaust can be exhausted efficiently. In addition, a tunnel-shaped air passage 3 is formed in the visor body 21 and a suction port 32 is formed in the inner wall surface 3 a of the air passage 3. O It is covered by the outer wall 3c of 3 o

 Therefore, the outer wall surface 3c of the ventilation path 3 functions as a cover for the suction port 32 with respect to rainwater blown to the side surface of the vehicle body, so that rainwater can be prevented from entering.

 In addition, since the suction port 3 2 is covered with the outer wall 3 c of the ventilation path 3, the suction port 3 2 is not directly exposed to the outside of the vehicle, and the generation of wind noise by the suction port 3 2 is prevented. be able to.

 Also, at the time of rainfall, rainwater enters the ventilation path 3 from the air intake 30 and accumulates at the bottom of the ventilation path 3. In this case, since the suction port 32 is formed above the bottom wall 3b of the ventilation path 3 and the bottom of the ventilation path 3 is formed in a gutter shape, the rainwater that has entered the ventilation path 3 has the force of the traveling wind. As a result, it flows on the bottom wall 3 b of the ventilation path 3 and is discharged from the air exhaust port 31. Therefore, it is possible to prevent rainwater that has entered the ventilation path 3 from entering the vehicle interior through the suction port 32.

 In addition, since the fin 32b projects outward from the front edge of the suction port 32 toward the rear, a negative pressure is generated behind the fin 32b to efficiently reduce the air in the vehicle compartment. It can be discharged well outside the cabin.

 As described above, the embodiment of the present invention has been described with reference to the drawings, but the specific configuration is not limited to this. For example, there is no particular limitation on the number and opening position of the suction ports, and the suction ports may be formed directly on the inner wall surface of the ventilation path without using a grill plate.

Further, the fin provided at the front edge of the suction port is not necessarily required, and a structure in which the suction port 32 is opened rearward as shown in FIG. 5 may be employed. No.

 In the case of a four-door vehicle visor according to the present invention, the door visor may be attached to the front seat window opening as in the embodiment, or may be attached to the rear seat window opening. Is also good. Industrial applicability

 As described above, in the automotive side visor according to the present invention (claim 1), the elastic seal piece that comes into contact with the window glass is protruded from the lower edge of the inner surface of the main body of the pier. Therefore, it is possible to prevent the traveling wind from entering the space inside the visor main body, and in particular, since the space inside the visor main body is integrated with the vehicle interior, the exhaust can be efficiently exhausted.

 In addition, a tunnel-shaped ventilation path is formed in the visor main body, and a suction port is formed on the inner wall surface of the ventilation path, so that the suction port is covered by the outer wall surface of the ventilation path. Therefore, it is possible to prevent rainwater blown into the side of the vehicle body from entering, and since the air outlet is not directly exposed to the outside of the vehicle, it is possible to prevent wind noise from being generated by the air outlet. In addition, since the suction port is formed above the bottom wall surface of the ventilation path and the bottom of the ventilation path is formed in a gutter shape (claim 2), rainwater that has entered the ventilation path is ventilated by the force of the traveling wind. It flows on the bottom wall of the road and is discharged from the outlet. Therefore, it is possible to prevent rainwater that has entered the ventilation path from entering the vehicle interior through the suction port.

 In addition, since the fin projects outward and rearward from the front edge of the suction port, a negative pressure is generated behind the fin, so that the air in the passenger compartment can be efficiently discharged to the outside of the passenger compartment.
