Abstract

A coupling mechanism for interfacing between a wiper and a wiper arm comprises an connector and at least one width-adjusting spacer member. The connector has a body, and the two sides of the body are defined as the outer side walls. The body has a stopping portion formed at one end thereof, and an engaging member is formed on the top surface of the body. The width-adjusting spacer member is selectively arranged on the outer side walls of the body. Thus, the width of the coupling mechanism can be adjusted according to the user'"'"'s demands, and thereby, enabling the wiper to be coupled to wiper arms having different specifications.

Claims

1. A coupling mechanism for connecting between a wiper and a wiper arm, comprising:

an connector including an body having at least one outer side wall, a stopping portion formed on one end of the body, and an engaging member formed on a top surface of the body; and

at least one width-adjusting spacer member selectively arranged on an outer side wall of the connector.

2. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 1, wherein the body has two protrusions respectively formed on the two sides of the bottom surface thereof, wherein the protrusions are connected to the stopping portion of the wiper arm.

3. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 1, wherein the engaging member is formed at one end of the body, away from the stopping portion.

4. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 1, wherein the width-adjusting spacer member is connected to the connector through a pivotal portion.

5. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 4, wherein a folded line is formed between the width-adjusting spacer member and the connector.

6. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 4, wherein the width-adjusting spacer member is connected to one end of the body, away from the stopping portion.

7. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 1, further comprising a wiper arm, wherein the wiper arm has an inner wall defined therein, the wiper arm is connected to the connector and the outer side of the width-adjusting spacer member, the engaging member of the connector is engaged to an engaging hole of the wiper arm, the width-adjusting spacer member is received partially or entirely between the inner wall of the wiper arm and the outer side wall of the body.

8. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 1, wherein there are two substantially symmetrically arranged width-adjusting spacer members.

9. The coupling mechanism for interfacing between a wiper and a wiper arm according to claim 8, wherein the two width-adjusting spacer members are connected by a connecting portion and the two width-adjusting spacer members are selectively arranged on the outer side walls of the connector.
