Abstract

An exemplary embodiment of the present invention includes a wiper blade assembly structure which has a space unit formed in a certain area of a support frame, to which a main arm of the wiper is coupled, and allows a replaceable adaptor to be detachably attached to the space unit to thereby enable various types of main arms to be coupled to a single support frame together with the replaceable adaptor.

Claims

1. A wiper blade assembly structure comprising:

a main arm;

an elongated support frame connected to the main arm, said support frame having a space unit defining a cavity therein and formed in a predetermined size in an upper central part of the support frame, a coupling member is formed in one side of the space unit, the coupling member including fixing pins longitudinally spaced along said frame and a flexible hook member, each of the pins and hook member extending generally parallel to each other from a lower central part of the support frame towards said upper central part, to respective free terminal ends, the hook member having an inclination surface formed in an upper part of the hook member; and

a replaceable adaptor including a coupling part comprising vertical grooves configured to detachably couple the space unit of the support frame in a vertical direction using the fixing pins and the inclination surface of the hook member, the replaceable adaptor configured to couple the main arm to the support frame,

wherein the main arm is inserted into the space unit of the support frame.

2. The wiper blade assembly structure according to claim 1, wherein an insert reinforcing frame is provided in the lower central part of the space unit where the replaceable adaptor is inserted.

3. The wiper blade assembly structure according to claim 2, wherein the insert reinforcing frame comprises a steel material.

4. The wiper blade assembly structure according to claim 2, wherein the insert reinforcing frame is longer than the space unit to thereby reinforce the strength of the support frame.

5. The wiper blade assembly structure according to claim 1, wherein a blade fixer is coupled to a lower part of the support frame and a blade is coupled to the blade fixer.

6. The wiper blade assembly structure according to claim 1, wherein the replaceable adaptor is configured to be replaceable depending on a different type of the main arm.

7. A wiper blade assembly structure comprising:

a main arm;

an elongated support frame connected to the main arm, said support frame having a space unit defining a cavity therein and formed in a predetermined size in an upper central part of the support frame, a coupling member is formed in one side of the space unit, the coupling member including fixing pins longitudinally spaced along said frame and a flexible hook member, each of the pins and hook member extending generally parallel to each other from a lower central part of the support frame towards said upper central part, to respective free terminal ends, the hook member having an inclination surface formed in an upper part of the hook member; and

a replaceable adaptor including a coupling part comprising vertical grooves configured to detachably couple the space unit of the support frame in a vertical direction using the fixing pins and the inclination surface of the hook member, the replaceable adaptor configured to couple the main arm to the support frame,

wherein the replaceable adaptor is selectively replaceable to a different type of the replaceable adaptor being configured to be coupled to the main arm.
