Description

[Detailed description of the invention] The present invention has a wing 3 installed above the rear window 2 of the automobile 1 at a distance from the rear window 2 and substantially parallel to the rear window 2 in the width direction of the rear window 2. This invention relates to an automobile rear window cleaning device that prevents raindrops, mud, and dust from adhering to the rear window by shaping airflow along the window.

This type of device has already been proposed in Japanese Utility Model Publication No. 50-27704, but in this conventional example, the wings are not easy to attach and detach, and therefore become a nuisance when washing a car, especially when washing an automatic car. There was a problem in that it took time and effort to remove the wings.

The present invention has been devised in view of these points, and its purpose is to provide a rear window cleaning device for an automobile in which the blades can be easily attached and detached and the attachment strength is high.

The present invention will be explained in detail below using examples.

In the figure, reference numeral 9 denotes a spoiler integrally formed of a weather-resistant composite or resin, with leg pieces 4 extending at right angles from both ends of a wing 3 having a length approximately equal to the width of the automobile 1. 4 leg pieces at the tip
The mounting rod 5 is shaped like a round bar and is longer than the width of the mounting rod 5. The mounting rod 5 is preferably a metal pipe 6 coated with synthetic resin.

The spoiler 9 is attached by a connector 7 to a rear door 10 of a coupe-style or van-like type of automobile 1 in which the rear window 2 is located at the rearmost position.

The connector 7 is a cylindrical bearing 11 with one end open and the other end closed.
The bearing 11 is fixed to the side edge of the rear door 10 by a U-shaped frame 12, and the mounting rod 5 is inserted through a window 13 provided in the center of the bearing 11 on the opposite side of the U-shaped frame 12.
is inserted into the bearing 11 and the fixing bolt 14 screwed into one end of the bearing 11 is tightened, and the spoiler 9 is connected by sandwiching the mounting rod 5 between the tip of the fixing bolt 14 and the closed surface of the other end of the bearing 11. It is fixed to the fixture 7.

On the other hand, as shown in FIG. 8, the U-shaped frame 12 has both side edges of the rear door 10 into which the rear window 2 is fitted. 15, and the side piece 15 on the opposite side from the bearing 11.
It is fixed to the rear door 10 by making a screw 16 screwed into it come into contact with the inner surface of the rear door 10. It falls within 18.

Further, the side piece 15 located on the inside of the vehicle of the U-shaped frame 12 is shorter in width than the other side piece 15, and a waterproof packing 19 is fitted to the inner peripheral edge of the opening 17, that is, the inner edge of the drain groove 18. The connectors 7 do not overlap with each other, and even if the connector 7 is attached to the rear door 10, it does not interfere with the opening and closing C of the rear door 10.

To attach the spoiler 9 to the rear door 10, first fix the connectors 7 to both side edges of the rear door 10 above the rear window 2, and then fit the mounting rods 5 at both ends of the spoiler 9 into the bearings 11 as described above. As a result, a gap 20 is formed between the blade 3 and the rear door 10, and the blade 3 is approximately parallel to the rear door 10 and inclined downwardly to the rear.
When the vehicle is running, the airflow A flowing in a substantially horizontal direction along the roof 8 of the automobile 1 is received by the lower surface of the blade 3 and its direction is changed to form an airflow B along the surface of the rear door 10 and the rear window 2. This prevents the rear window 2 from getting dirty by blowing away raindrops and dust that are about to land on the rear window 2.

In addition, this airflow B joins the airflow C that flows turbulently from the bottom of the car 1 through the bumper 21 upwards to form a backward flow D, and mud rolls up on the airflow C from below. The mud and dust are carried by the rear flow D and blown away to the rear of the automobile 1, thereby preventing mud and dust from adhering to the rear window 2 and the rear surface of the automobile 1.

Further, on the lower surface of the blade 3, a straightening blade 23 that runs in the width direction of the blade 3 is integrally protruded at an appropriate interval from the length direction. The different airflows A are rectified by the rectifying blades 23 and the rear window 2
This creates a uniform air flow B across the width of the tube.

As described above, the present invention has a wing horizontally mounted above the rear window at a distance from the rear window and approximately parallel to the rear window, so that air flows approximately horizontally backward along the roof of the vehicle when the vehicle is running. As a result, the airflow flowing along the rear window blows away raindrops and dust floating near the rear window, and these airflows are blown away. The airflow that flows along the rear window flows along the bottom of the car and merges with the downward airflow that rolls upward from the rear end of the car and flows toward the rear of the car. It creates a flowing rear airflow and blows mud and dust flying upwards to the rear, preventing dirt from adhering not only to the rear window but also to the rear of the car, improving rear visibility. In addition, the mounting rod at the end of the leg that extends from the wing through the window provided in this bearing is fitted into the bearing of the connector fixed to the rear door of the car, and the mounting rod is attached to one end of the bearing. Since both end surfaces of the mounting rod, which can slide freely in the axial direction within the bearing, are supported and fixed by the tip of the screwed fixing bolt and the closed surface of the other end of the bearing, the fixing bolt can be tightened by hand only. However, since the mounting rod is held in place, the wing can be installed securely, and there is no risk of the wing coming off during high-speed driving.Furthermore, the wing can be easily removed by loosening the fixing bolt. This has the advantage that it can be easily dealt with when it becomes a nuisance, for example, when washing a car, especially during an automatic car wash.
