Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a side ventilator provided on the side of a vehicle body so as to exhaust air inside the vehicle to the outside for ventilation.

(Prior Art) A side ventilator is provided at the lower side of a vehicle body to ventilate the interior of the vehicle.

This type of side ventilator has an outer case that opens with a slit in the outer panel of the vehicle body, a holding frame provided at the inner end of the outer case, and an intervening space between the inner end opening of the outer case and the holding frame. It consists of a one-way valve made of a flexible sheet of rubber or other material that only allows air to flow and blocks outside air from entering the room.

(Problem to be solved by the invention) In the above, the one-way valve is bent outward to exhaust indoor air to the outside, and closes its opening by contacting the holding frame against the outside air. However, when the one-way valve is closed, the one-way valve hits the crosspiece of the holding frame, producing a contact noise, and improvements to prevent this are desired.

The present invention has been developed to improve the above-mentioned problems, and its purpose is to fully demonstrate its function as a one-way valve while suppressing the occurrence of people coming into contact with it in the event of blockage as much as possible, and in terms of noise prevention. It provides an excellent side ventilator.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a portion such as a tongue piece that comes into sliding contact with the inner wall of the outer case at the free end of the one-way valve, and thereby a holding frame of the one-way valve. The gist of this is to reduce the impact on the body.

(Embodiment) Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fixed to.

An opening 504 is formed at the inner end of the duct portion 502 on the vehicle interior side, and a plurality of stop rods 505 are provided projecting from the upper and lower ends of the opening 504 spaced apart in the length direction. The case 5 is made of synthetic resin or the like. A one-way valve 6 made of a flexible elastic material such as rubber is arranged so as to close the inner end opening 504 of the duct part of the case 5, and a holding frame 7 is arranged on the back side of the one-way valve 6.

FIG. 7 is a front view of the one-way valve 6, and the one-way valve 6 has a horizontally long thick base 6 at the upper end.
01, and the base 601 is provided with a plurality of mounting holes 602 spaced apart in the length direction, which are connected to the stopper 505.
to overlap the surface of the base 601 with the upper end of the opening 504. The main body 603 of the one-way valve 6 is formed with a thin wall, and has thick ribs 604 for reinforcement around the four circumferences.
Further, in the embodiment, a horizontal bar-shaped rib 605 is provided at the intermediate portion, and a plurality of vertical ribs 607 connecting the rib 605 and the lower edge 606 of the rib 604 are provided.

Rib 606 on the lower edge of the above one-way valve 6
A plurality of tongue pieces 608 are provided hanging down and projectingly spaced apart in the length direction, and the rib 606 side is a free end, and the tongue pieces 6
08 may be formed integrally, or may be formed separately and the upper end portion of the tongue piece 608 may be integrally joined to the surface of the rib 606. The lower edge of the rib 606 forming the lower edge of the main body 603 is connected to the bottom wall 50 of the duct portion 502 while the base 601 is connected to the upper edge of the opening 504.
6. Set the height so that it faces above.

Reference numeral 7 denotes a holding frame, which is plate-shaped as shown in FIG. 4, and the peripheral frame portion 701 is dimensioned to be in contact with the peripheral portion of the opening portion 504, and the above-described stopper rods 505 are passed through the upper and lower frame portions 702 and 703. Mounting holes 704... are provided, the one-way valve 6 is made to face the edge of the opening 504 and then to the back side thereof, and a stopper 5 is provided in the mounting holes 704...
05... The protruding parts of the rear frame parts 702, 703 to the back surface through which they were passed are heated and melted, and the frame parts 702, 703 are joined to the edge of the opening part 504, and the one-way valve 6 is supported by the base part 601 being sandwiched. , the lower end is free.

A plurality of vertical beams 70 are arranged between the upper and lower frame portions 702, 703 and the left and right frame portions 705, 706 of the peripheral frame portion 701.
7... and in the embodiment, they are connected by one horizontal bar 708, and a plurality of openings 709 are formed between the vertical and horizontal bars 707..., 708.

The tip portion 710 of the surface facing the back surface of the main body 603 of the one-way valve 6 of the above-mentioned crosspieces 707... and 708 is formed into an arc shape as shown in FIGS. 5 and 6, and the tip portion may be V-shaped instead of the arc shape. , the tip portion 710 has a tapered shape.

Next, the function and effect will be described in detail. In FIG. 2, the right side of the figure is the inside of the vehicle, and the left side of the panel 3 is the outside of the vehicle. The flow of air inside the vehicle is allowed by opening the opening 707 of the holding frame 7 by bending the one-way valve 6 inward using the base 601 at the upper end as a fulcrum. When the air inflows, the one-way valve 6 hits the crosspieces 707, 708 of the holding frame 7 and closes the opening 709..., thus preventing the outside air from flowing into the passenger compartment, forming a one-way valve. .

By the way, after the one-way valve 6 discharges the air inside the vehicle compartment by the one-way valve action, the one-way valve 6 returns to the direction of the holding frame 7, and the main body 603 collides with the crosspieces 707 and 708, but the tongue piece 608 is attached to the lower edge of the main body 603. is provided, which slides into contact with the bottom wall 506 of the duct portion 502, and its frictional resistance attenuates the speed of the one-way valve 6 in the direction of the holding frame 7, and in the attenuated state, the crosspiece portion 707, 708, so the collision noise will not occur or will be extremely small. Therefore, the noise when the one-way valve is closed is suppressed as much as possible, and noise prevention can be achieved. Also, the crosspiece part 707,
Since 708 has a tapered shape such as an arc, the collision noise of the one-way valve is also reduced.

(Effects of the invention) As described above, the present invention reduces and suppresses the blockage noise of the one-way valve attached to the side ventilator as much as possible, and effectively prevents noise. This can be realized with a simple configuration of just providing a sliding contact portion such as a tongue piece.
