Abstract

Disclosed herein is a wiper blade assembly, including: an adaptor; and a cap member connected to a predetermined region of a front of the adaptor to rotate, wherein the cap member includes one or more hollows, the adaptor includes one or more pressing plates, and the cap member is rotated relative to the one or more pressing plates in a state where the one or more pressing plates are inserted in the one or more hollows. Since a wiper arm can be easily attached or detached by the rotation of the cap member, the wipe blade assembly can be easily attached to or detached from the wiper arm even by a beginner.

First claim

What is claimed is:

1. A wiper blade assembly, which is engaged with a wiper arm, comprising:
an adaptor; and
a cap member connected to a region of a front of the adaptor to rotate,
wherein the cap member includes a first hollow and a second hollow spaced from the first hollow,
wherein the adaptor includes a first pressing plate inserted into the first hollow and a second pressing plate inserted into the second hollow,
wherein the cap member is configured to rotate relative to the first pressing plate and the second pressing plate in a state where the first pressing plate and the second pressing plate are inserted into the first hollow and the second hollow, respectively,
wherein the adaptor includes an adaptor body and a press coupling unit located in front of the adaptor body,
wherein the press coupling unit includes a first press coupling unit located at a first side of the adaptor body and a second press coupling unit located at a second side of the adaptor body,
wherein the first press coupling unit includes a first elastic piece connected to the adaptor body, a first pressing plate located at an end of the first elastic piece, and a first support protruding from the first pressing plate,
wherein the second press coupling unit includes a second elastic piece connected to the adaptor body, a second pressing plate located at an end of the second elastic piece, and a second support protruding from the second pressing plate,
wherein one side of the first pressing plate is located at the end of the first elastic piece and the first support is located at the other side of the first pressing plate, and
wherein one side of the second pressing plate is located at the end of the second elastic piece and the second support is located at the other side of the second pressing plate.

2. The wiper blade assembly of claim 1 ,
wherein the wiper arm is a U-shaped hook type wiper arm, and the U-shaped hook type wiper arm includes a longitudinal support and a U-shaped hook located at a front end of the longitudinal support,
wherein the wiper blade assembly further includes a top cover connected with the adaptor, and
wherein the top cover includes a top cover body, a first wiper arm coupling unit located on the top cover body and coupled with the longitudinal support, and a second wiper arm coupling unit located in the front of the top cover body and coupled with the U-shaped hook.

3. The wiper blade assembly of claim 1 ,
wherein the cap member includes a cap unit covering the region of the front of the adaptor and lateral cap portions continuously formed to the cap unit and located at lateral sides of the cap unit,
wherein the cap unit includes an upper cap portion covering an upper surface of the front of the adaptor and a front cap portion continuously disposed to the upper cap portion and covering the front of the adaptor,
wherein the lateral cap portions include a first lateral cap portion located at a first lateral side of the cap unit and a second lateral cap portion located at a second lateral side of the cap unit, and
wherein the first lateral cap portion includes the first hollow, and the second lateral cap portion includes the second hollow.

4. The wiper blade assembly of claim 3 ,
wherein the cap member is configured to rotate such that the front of the adaptor is opened before the wiper arm is engaged and is closed after the wiper arm has been engaged.

5. The wiper blade assembly of claim 1 , wherein the first elastic piece and the second elastic piece have elasticity.

6. A wiper blade assembly, comprising:
an adaptor; and
a cap member connected to a region of a front of the adaptor to rotate,
wherein the cap member includes a cap unit covering the region of the front of the adaptor and lateral cap portions located at lateral sides of the cap unit, and including a first hollow and a second hollow spaced from the first hollow,
wherein the adaptor includes a first elastic piece, a first pressing plate which is located at an end of the first elastic piece and is inserted into the first hollow, a first support protruding from the first pressing plate, a second elastic piece, a second pressing plate which is located at an end of the second elastic piece and is inserted into the second hollow, and a second support protruding from the second pressing plate,
wherein the cap member includes a first locking jaw located at a first side of an inner end of the cap unit and a second locking jaw located at a second side of the inner end of the cap unit and spaced from the first locking jaw,
wherein the cap member is configured not to rotate in a state where the first support and the second support support the first locking jaw and the second locking jaw, respectively,
wherein the cap member is configured to rotate in a state where the first support and the second support release the first locking jaw and the second locking jaw, respectively,
wherein one side of the first pressing plate is located at the end of the first elastic piece and the first support is located at the other side of the first pressing plate, and
wherein one side of the second pressing plate is located at the end of the second elastic piece and the second support is located at the other side of the second pressing plate.

7. The wiper blade assembly of claim 6 ,
wherein the first support and the second support release the first locking jaw and the second locking jaw, respectively, by pressing the first pressing plate and the second pressing plate to move the first support and the second support inward.

8. The wiper blade assembly of claim 6 , wherein the first elastic piece and the second elastic piece have elasticity.
