Abstract

The present invention relates to a wiper blade assembling adapter, a wiper blade assembly, and a wiper apparatus. There is provided a wiper blade assembling adapter for coupling a wiper blade to a wiper arm, which has a distal end at which a plurality of coupling elements facing each other protrude inward from each side surface surrounding the adapter, the wiper blade assembling adapter including a main body part coupled to the wiper blade and a locking part rotatably provided in the main body part.

First claim

What is claimed is:

1. A wiper blade assembling adapter for coupling a wiper blade to a wiper arm, which has a distal end at which a plurality of coupling elements facing each other protrude inward from each side surface surrounding the adapter, the wiper blade assembling adapter comprising:
a main body part coupled to the wiper blade; and
a locking part rotatably provided in the main body part,
wherein
the main body part includes a plurality of guide parts including a first guide part and a second guide part, each having a) an insertion part into which a coupling element of the plurality of coupling elements of the wiper arm is inserted in a first direction and b) a catching part which extends from a distal end of the insertion part in a second direction different from the first direction and which is configured to block movement of the coupling element in the first direction after the coupling element moves in the second direction, the main body part having a hinge part disposed at one side of the main body part, and
the locking part has a) a rotary surface which is rotatably coupled to the hinge part and b) a cover surface which extends from the rotary surface and covers an outer surface of the wiper arm that surrounds the main body part, and
wherein the cover surface has a cover element that extends from a distal end toward the guide part, and the cover element covers at least the insertion part of the first guide part in a locking state.

2. The wiper blade assembling adapter of claim 1 , wherein:
the plurality of coupling elements of the wiper arm protrude inward at different heights; and
the plurality of guide parts are provided such that heights of the catching parts are different.

3. The wiper blade assembling adapter of claim 1 , wherein the insertion part and the catching part are connected to form an L-shape.

4. The wiper blade assembling adapter of claim 1 , wherein the first guide part is disposed adjacent to the hinge part and the second guide part is disposed farther removed from the hinge part than the first guide part.

5. The wiper blade assembling adapter of claim 4 , wherein the main body part further includes a step part provided at an outer surface facing the wiper arm.

6. The wiper blade assembling adapter of claim 5 , wherein the step part has a shape that is continuous with the insertion part of the first guide part.

7. The wiper blade assembling adapter of claim 4 , wherein a rotation limiting element protrudes from one side of the hinge part, and the locking part changes between an unlocking state, in which the cover surface rotates to cause an outer surface of the main body part to be exposed, and a locking state, in which the rotary surface rotates to cover the outer surface of the main body part.

8. The wiper blade assembling adapter of claim 1 , wherein the hinge part is provided as a pair of hinge parts at both sides of one surface of the main body part, each hinge part is provided in the form of a free end that is deformable so that distal ends of the hinge parts are able to come close to each other, and an elastic bar configured to connect the pair of hinge parts to each other is provided to maintain a gap between the hinge parts.

9. A wiper blade assembly comprising:
a wiper blade which has a close contact member configured to come in close contact with a surface of a target of close contact; and
an adapter which is fastened to the wiper blade and to and from which a wiper arm is attached and detached,
wherein
the adapter includes a main body part coupled to the wiper blade and a locking part rotatably provided in the main body part,
the main body part includes a) an insertion part into which a coupling element, which protrudes from a side surface of the wiper arm that surrounds a side surface of the main body part, is inserted and b) a catching part configured to catch the coupling element seated thereon after passing through the insertion part, and
the locking part has a) a rotary surface which is rotatably connected to the main body part and b) a cover surface which covers an outer surface of the wiper arm that covers an outer surface of the main body part, and
wherein the cover surface has a cover element that extends from a distal end toward the guide part, and the cover element covers at least the insertion part of the first guide part in a locking state.

10. The wiper blade assembly of claim 9 , wherein the wiper blade further includes an elastic member configured to provide an elastic force to the close contact member in a direction in which close contact with the close contact member occurs, and a cover member configured to cover the elastic member.

11. The wiper blade assembly of claim 9 , wherein the wiper blade further includes a coupling cover provided at a center and to which the adapter is coupled,
wherein a coupling hole in a cylindrical shape whose one side is open is provided in any one of the main body part and the coupling cover, and a bar-shaped seating element configured to be forcibly fitted to the coupling hole is provided at the other one of the main body part and the coupling cover.

12. The wiper blade assembly of claim 11 , wherein the seating element is fastened to the coupling hole and serves as a hinge shaft so that the wiper arm and the wiper blade rotate relative to each other.
