Abstract

PURPOSE:To surely wipe off fouling on a window glass plate with the quantity of injected washing water or liquid reduced. CONSTITUTION:One or plural parts of the base side of a wiper blade 3 are notched. A washing water injecting nozzle 5 is provided on a blade fixture 2 so as to be arranged in the notched parts 4 of the blade. A flexible pipe 6 for feeding washing water, arranged along a wiper arm 1, is connected to the nozzle 5. This restrains the consumption of the washing water and also surely wipes a glass surface by certainly injecting the washing water at a position directly before the moving direction of the wiper blade 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper device for reliably wiping a window glass in a window of an automobile or the like by reducing the amount of cleaning water or liquid for injecting dirt.

[0002]

2. Description of the Related Art The front window glass of an automobile becomes dirty and obstructs the field of view when the vehicle travels in the rain or otherwise. For this reason, a wiper device for wiping the window glass is additionally provided.However, in this conventional wiper device, a window provided by a nozzle provided on the hood within the swing range of the wiper arm with blades that swings left and right along the surface of the window glass Cleaning water or liquid is sprayed toward the surface to clean and wipe off dirt.

[0003]

When the window glass is extremely dirty and cannot be wiped by merely operating the wiper,
The cleaning water or liquid is sprayed, but it is desirable that the cleaning water is sprayed immediately before the moving wiper blade. However, since the swinging operation of the wiper blade and the spraying operation of the cleaning water are not synchronized, even if the cleaning water is sprayed to the rear position of the wiper blade, the dirt on the glass surface does not come off. For this reason, since the cleaning water is sprayed while the wiper blade is operated, the cleaning water is used in a large amount, and the cleaning water is consumed in a long drive in the rain.

It is an object of the present invention to inject the cleaning water without fail at the position just before the moving direction of the wiper blade so as to suppress the consumption and to surely wipe the glass surface.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. One or more notches are formed on the base side of a wiper blade, and the wiper blade is arranged in the notch. The gist of the present invention is that a nozzle for jetting cleaning water is provided on the blade attachment, and a flexible pipe for supplying cleaning water, which is arranged along the wiper arm, is connected to this nozzle.

[0006]

The wiper blade provided at the tip of the swinging wiper arm is notched on the arm mounting side, and the wartime water injection nozzle is arranged in the notch so that the wiper blade fitting is provided. As a result, when the wiper swings,
The tip surface of the wiper blade tilts in the front-back direction according to the moving direction, but when the wiper blade is tilted backward, the cleaning water is jetted from the nozzle of the blade cutout portion, so this sprayed cleaning water is Immediately before and always ahead. For this reason, the cleaning water must be
It is sprayed to the position of the wiper blade, and the wiping and cleaning by the blade can be surely performed even if the consumption amount is small. In particular, when dust is attached to the glass surface, the jet cleaning water precedes the wiper blade, so that the glass surface can be prevented from being scratched.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the illustrated embodiments. In the figure, reference numeral 1 is a wiper device arranged in a front window or a rear window of a vehicle such as an automobile. Although not shown, a wiper arm 1 having a required length can be lifted up and down on a wiper drive shaft driven in a forward and reverse direction by a motor. The blade attachment 2 is pivotally attached to the tip of the wiper arm 1 and the wiper blade 3 is detachably attached to the blade attachment 2.

The wiper blade 3 is provided with notches 4 at its base portion, that is, at the opposite end contacting the window glass surface, at the side end supported by the blade fitting 2, or at a plurality of locations. Also, the side that contacts the window glass surface is continuous. The cutout portion 4 has such a size that the washing water jet nozzle 5 is arranged so as to be seen through.

The cleaning water injection nozzle 5 is attached to the blade fitting 2 so that the tip of the nozzle faces the glass surface, and a flexible pipe such as a vinyl pipe arranged along the wiper arm 1 for supplying cleaning water. When two or more cutouts 4 are provided in the blade 3 while connecting the blades 6, one nozzle 5 is provided in each cutout 4, and the cutout 4 is filled with the jet cleaning water from the nozzles. The pitch is determined so that it is diffused on the glass surface.

[0010]

According to the present invention, the base side of the wiper blade is 1
Or, a plurality of cutouts are provided, and a cleaning water injection nozzle is provided in the blade attachment so as to be arranged in the cutout portion of this blade, and a flexible water supply for cleaning water is provided in this nozzle along the wiper arm. Since the structure is connected to the flexible tube, it always precedes the movement of the wiper blade, and the cleaning water is sprayed immediately before that, so the glass surface can be wiped and cleaned reliably, and the glass surface can be damaged by dust. Can be prevented.
