Description

와이퍼 연결 장치{Wiper Connecting Device}Wiper Connecting Device

본 발명은 와이퍼 연결 장치에 관한 것으로서, 보다 상세하게는 초기 곡률을 가지는 플랫 블레이드 와이퍼 조립체에 와이퍼 암을 연결하는 장치에 관한 것이다.The present invention relates to a wiper connection device, and more particularly, to a device for connecting a wiper arm to a flat blade wiper assembly having an initial curvature.

최근에는 와이퍼의 프라이머리 요크(primary yoke)와 세컨더리 요크(secondary yoke)가 없는 플랫 블레이드 와이퍼가 널리 사용되고 있다. 플랫 블레이드 와이퍼는, 블레이드 내측에 제공되며 초기 곡률을 가지는 지지 부재에 의하여 초기 곡률을 가지고 있으며, 차량의 유리창에 닿게 되면 휨 상태가 펴지면서, 복원력에 의해 차창에 밀착하게 된다.Recently, flat blade wipers without the primary yoke and secondary yoke of the wiper have been widely used. The flat blade wiper is provided inside the blade and has an initial curvature by a support member having an initial curvature. When the flat blade wiper comes into contact with the windshield of the vehicle, the flat blade wiper is brought into close contact with the windshield by a restoring force.

이러한 플랫 블레이드 와이퍼에서, 구동 수단에 의하여 구동되는 와이퍼 암과, 와이퍼 블레이드를 연결하기 위해서 와이퍼 연결 장치가 사용된다. 프라이머리 요크가 사용되는 일반 와이퍼에서는 프라이머리 요크 안쪽에 와이퍼 커넥터를 배치시킬 수 있기 때문에, 와이퍼 암의 단부가 프라이머리 요크에 의해 자연스럽게 가려지므로 미관상의 문제가 크지 않았다. 그러나 프라이머리 요크가 제공되지 않 는 플랫 블레이드 와이퍼에서는, 와이퍼 커넥터만 제공하는 경우, 와이퍼 암 단부가 노출되어 미관상 좋지 않는 단점이 있다. 그래서 플랫 블레이드 와이퍼에는, 와이퍼 커넥터에 더하여, 와이퍼 암의 단부를 가릴 수 있는 가이드 캡 부재가 널리 사용되고 있다.In such a flat blade wiper, a wiper connecting device is used to connect the wiper arm driven by the drive means and the wiper blade. In the general wiper in which the primary yoke is used, since the wiper connector can be disposed inside the primary yoke, the end of the wiper arm is naturally covered by the primary yoke, so the aesthetic problem was not large. However, in a flat blade wiper without a primary yoke, when only the wiper connector is provided, the wiper arm end is exposed, which is aesthetically disadvantageous. Therefore, in addition to the wiper connector, a guide cap member capable of covering the end of the wiper arm is widely used for the flat blade wiper.

종래의 플랫 블레이드 와이퍼에서는 와이퍼 지지 부재에, 축이 리베팅되어 있는 프레임을 고정시키고, 커넥터를 그 프레임의 축에 회전 가능하게 장착하고, 그 커넥터에 U 후크형 와이퍼 암을 체결시킨다. 그리고 가이드 캡을 장착하여 와이퍼 암의 단부를 가리도록 제공하는 구조였다.In a conventional flat blade wiper, a frame on which a shaft is riveted is fixed to a wiper support member, a connector is rotatably mounted on the shaft of the frame, and a U-hook wiper arm is fastened to the connector. The guide cap was mounted to cover the end of the wiper arm.

이러한 종래 기술에서는 커넥터를 장착한 후에 가이드 캡을 장착해야 하므로 부품수가 증대되고, 조립 공정도 두 차례에 걸쳐서 진행되는 단점이 있다.In this prior art, the number of parts is increased since the guide cap is mounted after the connector is mounted, and the assembly process is also performed twice.

본 발명은 이러한 종래 기술의 문제점을 해결하여, 플랫 블레이드 와이퍼에 있어서 와이퍼 커넥터와 가이드 캡을 일체화시킬 수 있는 와이퍼 연결 장치를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION An object of the present invention is to provide a wiper connecting device capable of integrating a wiper connector and a guide cap in a flat blade wiper by solving the problems of the prior art.

본 발명에 의한 와이퍼 연결 장치는, 초기 곡률을 가지는 와이퍼 조립체에 와이퍼 암을 연결시키는 와이퍼 연결 장치로서,The wiper connecting device according to the present invention is a wiper connecting device for connecting a wiper arm to a wiper assembly having an initial curvature,

결합공이 형성되어 있는 유 후크(U-Hook)형 와이퍼 암이 그 사이에 배치되며 와이퍼 암의 단부의 측면을 가리도록 제공되는 서로 마주보는 한 쌍의 측벽(11, 12)과,A pair of sidewalls 11 and 12 facing each other provided with a U-Hook type wiper arm having a coupling hole formed therebetween and covering the side of the end of the wiper arm;

상기 한 쌍의 측벽(11, 12)을 연결하며, 와이퍼 조립체에 회전 가능하게 장착되고, 상기 유 후크형 와이퍼 암의 U자형 내측 곡부(曲部)가 외측면에 안착되도록 제공되는 축부(60)와,A shaft portion (60) connecting the pair of side walls (11, 12) and rotatably mounted to the wiper assembly and provided such that the U-shaped inner curved portion of the u-hook wiper arm rests on an outer surface thereof; Wow,

상기 한 쌍의 측벽(11, 12) 사이에 제공되며, 와이퍼 암의 결합공에 걸리도록 제공되는 돌기(25)가 형성되어 있는 암(20)을 포함하는 레버 부재(15)를 포함한다.The lever member 15 is provided between the pair of side walls 11 and 12 and includes an arm 20 formed with a protrusion 25 provided to engage a coupling hole of the wiper arm.

상기 레버 부재(15)는 상하로 작동 가능하여 상기 와이퍼 암의 결합공과 돌기(25) 사이의 걸림 상태를 해제 가능하도록 제공되는 것이 바람직하다.It is preferable that the lever member 15 is provided to be operable up and down to release the locking state between the engaging hole of the wiper arm and the protrusion 25.

또한, 상기 축부의 회전에 따라 상기 한 쌍의 측벽도 회전 가능하다.In addition, the pair of side walls can also be rotated in accordance with the rotation of the shaft portion.

본 발명에 의하면 와이퍼 암이 연결되는 와이퍼 커넥터와, 와이퍼 암의 단부를 가리는 가이드 캡이 일체형으로 와이퍼 연결 장치가 제공되므로 부품수가 저감되고, 조립 공정 수도 줄어 들어 조립 효율을 높여 주는 효과가 제공된다.According to the present invention, since the wiper connector to which the wiper arm is connected and the guide cap covering the end of the wiper arm are provided in one piece, the number of parts is reduced and the number of assembly processes is reduced, thereby increasing the assembly efficiency.

이하에서는 첨부 도면을 참조하여 본 발명의 양호한 실시예에 대해서 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
