Two-blade windshield wiper device with built-in water spray device for automobiles.

The present innovation is a device of a two-blade windshield wiper with a built-in water spray device for motor vehicles any iru,

Windshield wipers with a wiper blade are known per se, but without a built-in water spray device.

Water spray devices are also known, but not in Connection to a two-blade wiper device.

The well-known windshield wipers and water spray devices have the. Disadvantage that the water spray device is attached to the vehicle body. When you press the same, the water jet sprayed onto the glass pane in an uncontrolled manner due to the driving speed There is a risk that oncoming vehicles as well as vehicles driving behind, First and foremost, in bad weather periods with existing layers of salt and dirt, immediately dirty the windows and any view is taken for seconds.

Even when used immediately with conventional windshield wipers must be driven on for too long in a blind state, so that there is a greatest risk of accidents in these unavoidable seconds.

The present innovation, on the other hand, has the task of using the two-blade windshield wiper with built-in water spray device, when using them, you can immediately achieve clear washing or wiping effects on the car window.

The two-blade windshield wiper device with built-in water spray device, can still be easily mounted on motor vehicles like the previous windshield wipers. In addition, the individual parts of the An innovation with a simple structure so that it can be dismantled and replaced for all vehicle types without difficulty.

Another advantage of the innovation is that instead of the previous one, a wiper blade is added so that a water channel is arranged between the wiper blades, which is provided with three or more holes and aims the water jet at the glass pane.

The water channel, which is incorporated in the windshield wiper rubber, runs along the entire length of the wiper. Both sides of the water channel are each closed to only through the holes that are directed towards the pane of glass to spray water onto the respective wiping surface »

The water connection is in the middle of the two-blade windscreen wiper device. The water hose for the water connection leads to the windscreen washer system conventionally installed in the vehicle interior and connected to them.

Another advantage of the innovation is, as can be seen from Figure 1, that the production of this device can be injected (extruded) in one operation, and that the water channel then on both sides can be closed at the end by a respective rubber stopper. In continuation of this idea, the rubber profile can also be replaced when it has worn out, without having to remove the bracket holder must replace

Further details of the innovation are to be found in an exemplary embodiment infer that is described in more detail below with reference to three figures.

Figure 1 shows in a front view the outlines of the bracket holder, with the two-blade windshield wiper device according to the invention is equipped.

Figure 2 shows in a section and in an enlarged view Double-leaf rubber profile with the retaining hooks. The cut image

was created by cutting the bracket bracket according to Section line I - I.

FIG. 3 shows a section, also in an enlarged representation the rubber sheet double profile with the water connection for the Water channel. The sectional view is the result of a cut, according to the section line II - II.

In Figure 1 is the front view of the two-blade windshield wiper device with built-in water spray device with the bracket holder, dashed version, designated in its entirety by 10. The water channel 3, which runs through the rubber profile 1, can be seen. The water channel is sealed on both sides with a rubber stopper 2 at the end. The spray holes are labeled 4.

Figure 2 shows the section through the section line I - I. Here is the Bracket holder 5> of the bracket 6 to recognize. You can still see the hatched plug 7 · pos. 8 shows two spring plates 9 which run through the entire length of the windshield wiper in order to be curved Slices to effect a favorable investment.

In Figure 3, the water connection to the water channel 3 can be seen. You can also see a section through one of the spray nozzles 13

The better mode of operation of the two-blade windshield wiper device with a built-in water spray device is the following ι

An additional wiper profile b in FIGS. 1 and 2 produces a better windshield wiping effect. The spray nozzle assembly between the two Schei'benwischprofilen causes that always when wiping, too if it does not rain, without a lot of water, a good washing of the window is guaranteed. Among other things, the water is not immediately from the Washed windshield, but stays between the two wiper blades for a certain time when the windshield wiper moves «
