Abstract

PURPOSE:To coat a wind shield glass with washer liquid and enhance the washing effect of a wiper equipment by having washing liquid guided through a pipe within an wiper arm and quirted out of nozzles formed on a wiper blade. CONSTITUTION:A wipe pipe 1 connected with a wiper pump is, after being passed through a wiper attaching screw 2, installed within a wiper arm 3 and communicated with a wiper blade 4 and a wiper rubber 5. And on the wiper rubber 5, many nozzles 20 for squirting washer liquid are formed so that the wind shield glass can be coated with washer liquid evenly and directly. Therefore, washing can be attained with a little volume of washer liquid without the adverse effect of wind pressure. As washing is carried out while the glass is being coated with the liquid, furthermore, the washing effect can be improved without any obstruction to the view.

Description

[Detailed Description of the Invention] The present invention provides wipers and window washers for vehicles, etc.
Regarding the mechanism.

The conventional washer mechanism, in which the washer liquid injected onto the windshield from a nozzle installed in the bonnet is wiped away with a wimp, has a long distance between the nozzle and the windshield surface.

(1) Physically, a certain amount of liquid is required, but the wiping action of the wiper wipes the liquid away before the liquid itself has its full effect, so it is not enough to be effective. 1
Easily soiled inside (3) The washer fluid temporarily blocks the view.

There were drawbacks such as.

The object of the present invention is to obtain functions that improve the above-mentioned conventional drawbacks.

An example is shown in FIG.

Washer pipe 1 connected to washer pump
is installed inside the wiper arm 3 via the inside of the wiper mounting screw 2, and the wiper blade 4. This leads to wiper rubber 5.

As shown in FIG. 2, the wiper rubber of this blade has a washer fluid hole 1 inside and a plurality of nozzles 2 communicating with the washer fluid hole 1 on the outside.

By applying the necessary pressure from the washer pump, a corresponding amount of washer fluid is delivered from the nozzle hole.

In this case, since the washer liquid is applied directly and evenly to the glass surface, the effect can be obtained with a small amount of liquid and it can be used continuously.

At the same time, it is possible to obtain performance that improves other conventional drawbacks.

[Brief explanation of drawings]

FIG. 1 shows an embodiment of the invention.

Claims (2)

[Claims] (1) A wiper device that sends washer fluid through a pipe installed on the wiper arm from a nozzle installed on the blade. (2) Wiper rubber with a washer fluid hole inside and multiple nozzles communicating from the fluid hole
