Abstract

An adaptor and coupling structure of a vehicular wiper arm are provided. The adaptor has an altered pin coupling structure that is capable of coupling to a variety of wiper arms without using rivets, is easily coupled without manipulating the pin of a wiper arm, is coupled to pivot centrally around a wiper frame, and increases the pivoting supporting strength of a wiper. The pin coupling structure includes a pivoting portion pivotably inserted in a mounting bracket of the wiper frame. The pivoting portion forms a hollow part that guides and couples with the pin of the wiper arm. The wiper frame forms a guide notch for guiding and coupling with the pivoting portion.

Claims

1. An adaptor inserted and installed on a mounting bracket of a wiper frame having a wiper blade installed thereon, the adaptor comprising:

a pivoting portion configured to be inserted along the mounting bracket and defining a downwardly facing convex arcuate surface;

a pin hole for guiding and inserting a first pin of a wiper arm;

a rib extended downwardly from adaptor, wherein the rib is mounted over an upper edge of the mounting bracket of the wiper frame, and

a hollow part integrally formed within the pivoting portion for guiding and coupling with a second pin of a wiper arm,

wherein the wiper frame forms a hole corresponding to the pin hole,

wherein the pivoting portion is guided and coupled by a guide notch provided in the wiper frame, and

wherein the guide notch has an upwardly facing open end and defines an upwardly facing concave arcuate surface therein receiving and fixing with the arcuate surface of the pivoting portion.

2. The adaptor according to claim 1, further comprising an air spoiler for directing oncoming air in an upward direction.

3. A coupling structure of a wiper comprising:

a wiper arm including one of a first and second pins;

a wiper frame including a mounting bracket that defines a guide notch; and

an adaptor inserted and installed on the mounting bracket,

wherein the adapter includes;

a pin hole formed therein for receiving the first pin;

a pivoting portion configured to be inserted along the mounting bracket and defining a downwardly facing convex arcuate surface;

a hollow part formed in the pivoting portion for guiding and coupling with the second pin; and

a rib extending downwardly from the adaptor,

wherein the wiper frame forms a hole corresponding to the pin hole,

wherein the rib is mounted over an upper edge of the mounting bracket of the wiper frame,

and wherein the guide notch has an upwardly facing open end and defines an upwardly facing concave arcuate surface therein receiving and fixing with the convex arcuate surface of the pivoting portion.

4. The coupling structure according to claim 3, wherein the guide notch is formed symmetrically in duplicate.
