Abstract

The present invention relates to a flat wiper blade for a vehicle, and more particularly, to a flat wiper blade for a vehicle, which is constructed to allow a blade and spoilers to be integrally assembled with each other via an auxiliary coupler so that the blade and spoilers, fitted into and coupled to the auxiliary coupler, can be easily decoupled from the auxiliary coupler and replaced with new ones or different ones. According to the present invention, spoilers and a blade, which are fitted and coupled into an auxiliary coupler, can be easily replaced through simple manipulation. Spoilers having a variety of colors or patterns can be easily installed, so that a wiper blade for a vehicle can be decorated in various ways in conformity with the taste and character of a user. Also, since manufacturing and assembling processes can be simplified, manufacturing costs can be significantly reduced.

Claims

1. A flat wiper blade for a vehicle, comprising:

a flat frame having a predetermined curvature;

an auxiliary coupler having a through-opening which is defined through an upper part of the auxiliary coupler to extend in a lengthwise direction thereof, and into which the flat frame can be inserted and coupled, and a pair of bent locking portions, which are formed in a lower part of the auxiliary coupler to extend in the lengthwise direction thereof;

a blade having projecting locking portions which are formed at an upper end thereof and can be fitted into the bent locking portions of the auxiliary coupler, the blade being in direct contact with a windshield glass of a vehicle to perform a wiping function;

spoilers each having locking grooves which are defined on inner wall surfaces of a lower part thereof to extend in a lengthwise direction of the spoiler, and into which the auxiliary coupler can be fitted and coupled; and

a bracket coupled to an intermediate part of the auxiliary coupler, wherein the flat frame is coupled into the through-opening of the auxiliary coupler, the auxiliary coupler is fitted into the locking grooves of the spoilers, and the blade is coupled into the bent locking portions of the auxiliary coupler, whereby the blade and the spoilers are integrally assembled with each other via the auxiliary coupler.

2. The flat wiper blade according to claim 1, further comprising:

end caps locked to both ends of the auxiliary coupler, wherein each end cap has locking protuberances formed on an inside lower end thereof such that the locking protuberances are locked and secured into locking holes which are defined adjacent to both width wise end portions on each end of the auxiliary coupler.

3. The flat wiper blade according to claim 2, wherein the spoilers are structured to be capable of having various colors, and various content, such as ads, telephone numbers, images, photographs, characters, etc., can be printed on the spoilers, so that, after a user unlocks the end caps, the spoilers can be replaced with those having different colors or printed with different content, in conformity with the user'"'"'s taste or need.

4. The flat wiper blade according to claim 1, wherein the flat frame is made of carbon steel, and the auxiliary coupler and the spoilers are made of soft plastic.

5. The flat wiper blade according to claim 1, wherein the spoiler is formed to have a triangular sectional shape.

6. The flat wiper blade according to claim 1, further comprising:

a bracket cover, locked to the bracket from the top to cover the bracket.

7. The flat wiper blade according to claim 2, wherein the spoiler is formed to have a triangular sectional shape.

8. The flat wiper blade according to claim 3, wherein the spoiler is formed to have a triangular sectional shape.

9. The flat wiper blade according to claim 4, wherein the spoiler is formed to have a triangular sectional shape.

10. The flat wiper blade according to claim 2, further comprising:

a bracket cover, locked to the bracket from the top to cover the bracket.

11. The flat wiper blade according to claim 3, further comprising:

a bracket cover, locked to the bracket from the top to cover the bracket.

12. The flat wiper blade according to claim 4, further comprising:

a bracket cover, locked to the bracket from the top to cover the bracket.
