Connecting apparatus for wiper, wiper blade assembly, and wiper device

Abstract

The present disclosure relates to a connecting apparatus for a wiper, a wiper blade assembly, and a wiper device. A connecting apparatus for a wiper for interconnecting a wiper blade and a wiper arm includes: a main body portion having one surface on which the wiper arm is seated; and a cap portion rotatably provided on one side of the main body portion and configured to cover the wiper arm seated on the main body portion according to a rotation angle. The main body portion includes a groove configured to engage a rotation center of the cap portion, and a locking portion configured to be able to interfere with positional movement of the cap portion.

What is claimed is: 
     
         1 . A connecting apparatus for interconnecting a wiper blade and a wiper arm, the connecting apparatus comprising:
 a main body portion having one surface on which the wiper arm is seated; and   a cap portion configured to cover the wiper arm seated on the main body portion;   wherein the main body portion comprises:   a groove configured to engage a protrusion of the cap portion to a first position or a second position; and   a locking portion configured to expose to an opening of the cap portion,   wherein the protrusion of the cap portion is configured to move to the first position where the cap portion is locked by a protrusion of the locking portion, or the second position where the cap portion is movable.   
     
     
         2 . The connecting apparatus of  claim 1 , wherein the groove has a form in which a first part configured to restrict a movement of the cap portion and a second part configured to allow the movement of the cap portion, and
 wherein the first position is where the protrusion of the cap portion is placed in the first part, and the second position is where the protrusion of the cap portion is placed in the second part.   
     
     
         3 . The connecting apparatus of  claim 1 , wherein the protrusion of the locking portion is configured to contact with the cap portion to restrict a movement of the cap portion. 
     
     
         4 . The connecting apparatus of  claim 1 , wherein the locking portion is formed in the shape of a cantilever in which the opposite side of the protrusion of the locking portion is fixed. 
     
     
         5 . The connecting apparatus of  claim 1 , wherein the protrusion of locking portion is configured to dislocate from the cap portion by an external force. 
     
     
         6 . The connecting apparatus of  claim 1 , wherein the protrusion of the cap portion is configured to movable to the second position when an external force is applied to the locking portion. 
     
     
         7 . The connecting apparatus of  claim 1 , wherein the opening of the cap portion is configured to engage the protrusion of the locking portion. 
     
     
         8 . The connecting apparatus of  claim 1 , wherein the main body portion comprises a pair of hinge portions in which the groove in a penetrating or non-penetrating form are provided, and
 wherein the locking portion is disposed in parallel with the hinge portions between the pair of hinge portions.   
     
     
         9 . The connecting apparatus of  claim 8 , wherein the hinge portions are surrounded by the cap portion, and
 wherein the locking portion has a shape that is more extended than the hinge portions, while one end thereof is extended to outside of the cap portion so as to be exposed to the outside.
