Abstract

PROBLEM TO BE SOLVED: To regenerate and reuse a wiper blade so as to prevent adhesion of grains and powder disturbing visibility by wiping a glass surface contact part of blade rubber of a wiper blade with a cleaning agent, formed of a volatile solvent, and eliminating an oxide film formed at the blade rubber. SOLUTION: Blade rubber 16 has a tapered glass surface contact part 16B, brought into flexible contact with the glass surface 20 to clean the glass surface 20 while sliding on the glass surface 20, at the tip edge of a rubber body 16A. The glass surface contact part 16B of the blade rubber 16 of a wiper blade 10 is wiped with a cleaning agent, formed of a volatile solvent, so as to eliminate an oxide film 18 formed at the blade rubber 16. The wiper blade 10 is thereby regenerated and prevents fine grains or powder of the oxide film from sticking to the glass surface 20 from the wiper blade 10, thus preventing the visibility of glass from being disturbed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning a wiper blade for an automobile and a cleaning agent used for carrying out the method.

[0002]

2. Description of the Related Art Wiper blades for automobiles are used to wipe off water droplets on the surface of windshields such as windshields when running in rain, and to wipe off dirt or dirt attached to the surfaces of windshields.

[0003] When oily components in waste gas or sap of plants that are scattered in the air adhere to the windshield of an automobile and stain the glass surface, a cleaning solution for cleaning the glass surface is blown and wiped off. Although dirt is removed, if the wiper blade deteriorates due to long-term use, wiping the glass surface with a wiper blade will deteriorate the visibility of the glass even if these dirt is removed, and will especially remove dirt such as oily components or sap. It is known that if the deteriorated wiper blade is continuously used without being taken, the visibility of the glass is rather deteriorated.

[0004] The deterioration of the surface of the blade rubber of the wiper blade is caused by the fact that it receives sunlight and reacts with oxygen in the air to form an oxide film over a long period of use.
In addition, if the wiper blade thus deteriorated is used continuously, the reason for obstructing the view of the glass surface is that the oxide film is rubbed by the glass surface during use of the wiper blade to form fine particles or powder on the glass surface. This is because it adheres, and when this is combined with dirt such as oily components or sap adhered to the glass surface, the visibility of the glass is further deteriorated.

[0005] In the prior art, the blade rubber of the wiper blade was refrained from touching the glass contact portion for the purpose of preventing damage. Therefore, when the wiper blade deteriorates, it is discarded and replaced with a new wiper blade. As a result, the parts were consumed greatly, which was extremely uneconomical.

[0006]

The problem to be solved by the present invention is that the wiper blade can be reclaimed and used, and particles or powders which obstruct the view of the glass surface from the wiper blade side adhere. An object of the present invention is to provide a wiper blade cleaning method and a cleaning agent used for performing the method.

[0007]

A first object of the present invention is to form a blade rubber of a wiper blade by wiping a portion of the blade rubber which should come into contact with a glass surface with a cleaning agent comprising a volatile solvent. It is another object of the present invention to provide a method for cleaning a wiper blade, characterized by removing an oxide film.

[0008] A second object of the present invention is to provide a wiper blade, characterized in that the blade rubber of the wiper blade is made of a volatile solvent for wiping an oxide film formed on a portion to be brought into contact with the glass surface. It is to provide a cleaning agent.

As described above, when the blade rubber of the wiper blade is wiped with a cleaning agent composed of a volatile solvent to remove the oxide film formed on the blade rubber, the wiper blade is regenerated. Fine particles or powder of an oxide film do not adhere to the glass surface from the wiper blade, and the view of the glass is not obstructed.

When the wiper blade is maintained as described above, the wiper blade can be continuously used, which is very economical. In addition, the blade rubber of the wiper blade becomes thin each time the oxide film is wiped off, so even if it receives the pressure from the wiper arm, the contact pressure on the glass surface becomes small or the glass surface is not sufficiently wiped off with dirt. Therefore, after a certain amount of maintenance, replacement is required.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is used by being attached to the tip of a wiper arm (not shown), but is cleaned by the method of the present invention. 1 shows a wiper blade 10 which comprises a blade lever 14 having a grip 12 to be pivotally supported by a wiper arm and a blade rubber 16 removably attached to the blade lever 14.

As shown in FIG. 2, the blade rubber 16 is a tapered glass which cleans the glass surface 20 while sliding on the glass surface 20 by flexibly contacting the tip edge of the rubber body 16A. It has a surface contact portion 16B.

As shown in FIG. 3, the blade rubber 16 receives sunlight and reacts with oxygen in the air as it is used for a long time to form an oxide film 18. This oxide film 18
When rubbed by the glass surface 20 during use of the wiper blade 10, as shown in FIG. 4, it tends to adhere as fine particles or powder to the glass surface 20 to form the obstruction layer 22. In particular, this view obstruction layer 22 further deteriorates the view of the glass when it is combined with dirt such as an oily component or sap adhered to the glass surface 20.

In the method of the present invention, as shown in FIG. 5, the blade rubber 16 of the wiper blade 10 is
The object of the present invention is to remove the oxide film 18 formed on the blade rubber 16 by wiping the glass surface contact portion 16B to be brought into contact with zero with a cleaning agent composed of a volatile solvent. It is preferable that the cleaning agent is composed of, for example, a diluent obtained by appropriately diluting ethanol as a main component.

As shown in FIG. 5A, a cleaning agent 26 is immersed in a suitable liquid-permeable cloth 24, and the glass surface contact portion 16B of the blade rubber 16 is removed with the cloth 24. It can be done by wiping. Thus, the blade rubber 16 from which the oxide film 18 has been removed is shown in FIG.
As shown in FIG. 2, the first blade rubber 16 in FIG. 2 has a glass surface contact portion 16B which is thinner than the glass surface contact portion 16B but has a regenerated glass surface contact portion 16B. Since the cleaning agent 26 is volatile, it is scattered immediately after wiping and the blade rubber 16 is dried.

Therefore, even if the wiper blade 10 is continuously used, fine particles or powder of the oxide film 18 do not adhere to the glass surface 20 from the wiper blade 10, and the view of the glass is not obstructed. Since the glass surface contact portion 16B of the blade rubber 16 is not touched directly with the hand but is wiped with the cloth 24, the surface is not damaged, so that use of the wiper blade 10 is not hindered.

As described above, the wiper blade 10
The blade rubber 16 becomes thin each time the oxide film 18 is wiped off, so that the contact pressure on the glass surface 20 becomes small or the wiping of the glass surface 20 becomes insufficient even under the pressure from the wiper arm. Therefore, it is necessary to replace the battery after a certain amount of maintenance.

In the above-described embodiment, the cleaning agent is immersed in the surface of a cloth such as a rag to wipe off the oxide film 18 on the glass surface contact portion 16B of the blade rubber 16. However, as shown in FIG. A large number of disposable cleaning pieces 38 in which a cleaning agent 36 is soaked in a small piece of cloth 34 of a predetermined small size sufficient to wipe off the oxide film 18 of the contact portion 16B are stored in the closed container, and if necessary, the cleaning pieces 38 Can be taken out of the closed containers one by one and used for cleaning the blade rubber 16.

[0019]

According to the present invention, as described above, the portion of the blade rubber of the wiper blade which should come into contact with the glass surface is wiped with a cleaning agent comprising a volatile solvent to remove the oxide film formed on the blade rubber. Since the wiper blade is removed, the wiper blade is regenerated and fine particles or powder of an oxide film do not adhere to the glass surface from the wiper blade, and the view of the glass is not obstructed.

Further, when the wiper blade is maintained in such a manner, the wiper blade can be continuously used, so that the use period of the wiper blade is extended, so that the consumption of automobile parts is reduced, which is very economical. It is.
