DEVICE FOR PROTECTING THE REAR WINDOW OF THE CAR FROM POLLUTION

The inventive utility model relates to devices for directing air flow along the roof of a car body to protect the rear window from pollution and can be installed on the car at the request of the owner.

Known models of bodies with a small angle of inclination of the rear door to the hatchback type roof, these include, in particular, cars of the VAZ-2108,2109 models. The rear of this type of body, including the rear window, is very dirty when driving in rain, snow, or on a dusty road. To remove dirt from the rear window, only some modifications of VAZ cars are equipped with wipers / 1 /, which clean part of the glass accessible to the brushes, increase the cost of the car, and distract the driver's attention.

Known windshields that are installed to prevent pollution on the sides of the rear window / 2 /. Strong fixing of such shields on VAZ-2108,2109 bodies without drilling holes in the rear door was unattainable, the shields are torn off by the air stream.

Also known are the designs of transverse profile flaps guiding the air flow along the rear door, preventing its pollution. Thanks to the correctly positioned guide plate above the trailing edge of the roof of a Volkswagen car, Option 1600 was able to reduce glass pollution by three or more times / 3 /.

on the interface between the roof and the rear wall of the body. The means of fastening a similar profile shield on the car body as an additional device must be reliable, not require drilling in the body, and allow quick installation and removal of the shield. The patent literature describes gluing or mounting on the suction cups of the transverse elements to the roof of the body / 5.6 /, however, in the first case, the possibility of removal is excluded, and in the second, reliability is not achieved.

By the claimed device, the transverse shield consists of a front and rear part, located at an angle equal to the angle between the roof and the rear window of the corresponding model of the car and is equipped with racks with the ends turned inwards. The racks are made holes for screws, threaded with strips installed on the inside of the racks. Racks are deviated from the vertical towards the back and the roof. The holes in the uprights can be made with sockets for screw heads. At the rear of the flap, uniform longitudinal slots can be made. The racks deviated from the vertical towards the rear and the roof allow you to place a shield over the interface between the roof and the rear window, and the racks are fixed behind the side of the drainage groove in the place where it has a constant height, that is, at a sufficient distance from the end of the groove. The curved edges of the uprights and sidewalls cover the sides from the outside, the strips are introduced into the grooves from the inside, the cross sections of the grooves only partially overlap the strips and this slightly complicates the flow of water. With the screws tightened, the grooves are tightly sandwiched between the uprights and planks and the shield is not securely fixed over the body. No drilling of mounting holes in the body is required. To improve aerodynamics, holes in the uprights can be made with sockets for screw heads, and uniform longitudinal cuts can be made in the rear part of the shield.

A device for protecting the rear window from pollution contains a transverse flap 1, consisting of a frontal 2 and a rear part 3 located at an angle equal to the angle between the roof and the rear door of the corresponding car model. Racks 4 are welded to the shield 1, deviated from the vertical to the side and to the back. Racks 4 are made of steel strip, their ends 5 are bent inwards (FIG. 2). In the racks 4, holes 6 are made for screws, threaded to the strips 8 installed on the inside of the racks 4. In the racks 4, sockets 9 are made for the screw heads. In the rear part of the flap 3 there are twelve equally spaced slots 10. The device is mounted on the side 11 of the drainage groove of the car roof. For proper installation of the device must be maintained equal to the dimensions of T (figure 2).

The installation of the device is as follows. The straps 8 are connected by screws 7 to the posts 4, leaving gaps between the posts 4 and the straps 8 slightly more than the thickness of the side 11 of the drainage groove. Then the device is installed over the roof of the car, having maintained the recommended dimensions B and T, and tighten the screws, clamping the sides 11 between the trims 8 and racks 4. When the car is moving, the air flow is guided downward along the rear door and protects the glass from pollution from the roadway.
