본 발명은 자동차의 윈드 시일드에 맺힌 눈 등을 제거해 주는 와이퍼 브레이드에 관한 것으로, 특히 복수개의 브레이드 러버를 와이퍼 브레이드에 설치함으로써, 브레이드 러버를 장기간 사용시 마모되어 이를 새것으로 교환해 주는 작업 주기를 반감시켜 교환 작업시 발생하는 불편함을 없애는 동시에 원가 절감의 효과를 얻을 수 있는 자동차용 와이퍼 브레이드에 관한 것이다.The present invention relates to a wiper braid that removes snow, etc. formed on the windshield of an automobile, and in particular, by installing a plurality of braid rubbers on a wiper braid, the work cycle of wearing the braid rubber for a long time and replacing it with a new one is halved. The present invention relates to a wiper braid for automobiles, which can eliminate the inconvenience caused during replacement work and at the same time, reduce the cost.

일반적으로, 자동차에 설치되는 와이퍼는 비나 눈이 내릴때 운전자의 시계가 방해받는 것을 막기 위하여 앞면, 뒷면 유리창을 닦아 내는 작용을 하며 그 구성은 와이퍼 브레이드, 와이퍼 암, 전동기, 링크기구 등으로 되어 있다.In general, the wiper installed in the car wipes the front and rear windows to prevent the driver's watch from being disturbed when it rains or snows, and its configuration consists of a wiper blade, a wiper arm, an electric motor, and a link mechanism. .

이러한 와이퍼의 구성부 중 와이퍼 브레이드는 앞면 유리에 맞는 고정구로 지지하고, 고정구의 중앙부분을 와이퍼 암의 끝부분을 끼우도록 되어 있다. 또 와이퍼 암의 다른 끝쪽을 볼트 또는 세레이션으로 링크에 결합된다. 와이퍼 암의 스프링은 와이퍼 브레이드가 적절한 힘으로 앞면 유리와 접촉시키는 역할을 한다.Among the components of the wiper, the wiper braid is supported by a fixture adapted to the front glass, and the center portion of the fixture is fitted with the end of the wiper arm. The other end of the wiper arm is then bolted or serrated to the link. The spring of the wiper arm serves to make the wiper braid contact the front glass with proper force.

그리고 작동중의 와이퍼 브레이드의 접촉 각도에 있어, 전면 유리와의 접촉 각도가 너무 크거나 작으면 닦는 상태가 불량해지며 전면 유리와의 접촉 각도는 30~50°정도를 유지하도록 해야 한다.And in the wiper braid contact angle during operation, if the contact angle with the windshield is too big or too small, the wiping condition will be poor and the contact angle with the windshield should be maintained at 30 ~ 50 °.

하지만, 이처럼 작용하는 와이퍼 브레이드를 구성하는데 있어서, 종래에는 도면 제1도에 도시된 바와 같이 하부에는 윈드시일드(도면중 미도시)에 접촉된 상태로 움직이면서 닦는 작용을 하는 립(12)을 형성하고 상부에는 고정될 수 있도록 수개의 플립(14)을 길이 방향으로 형성하여 된 브레이드 러버(10)와; 상기 플립(14)에 삽설되게 함실(22)을 형성하되 그 저면에는 삽지부(24)를 각각 형성하여 된 괘정구(20)와; 그 괘정구(20)의 상면에 용접 설치된 레버(30)로 구성되었다.However, in the construction of the wiper braid acting as described above, as shown in FIG. 1, a lip 12 is formed on the lower portion of the wiper while moving in contact with a windshield (not shown). And the braid rubber 10 formed by forming a number of flip 14 in the longitudinal direction to be fixed to the upper; A ruler 20 which forms a chamber 22 to be inserted into the flip 14, and an insertion part 24 is formed on the bottom thereof; It consisted of the lever 30 welded to the upper surface of the ruler 20.

이렇게 구성된 종래의 기술에는, 비나 눈 등에 의해 유리창이 더러워지게 되면, 운전자의 시야를 방해하게 된다. 그러면 이를 제거하기 위해서 와이퍼 장치를 작동시키게 된다. 이러한 과정으로 상기 와이퍼 장치를 장시간 사용하게 되면 문제가 발생하게 되는데, 상기 와이퍼 장치의 브레이드 러버가 마모되어 본래 기능을 제대로 수행할 수 없게 된다.In the conventional technology configured as described above, when the window becomes dirty by rain or snow, the driver's view is obstructed. The wiper device is then activated to remove it. In this process, a problem occurs when the wiper device is used for a long time, and the braid rubber of the wiper device is worn and thus cannot properly perform its original function.

즉 유리창을 제대로 닦아주지 못해 유리창의 얼룩 등이 군데군데 남게 되므로, 운전자의 시야 확보에 어려움이 생겨 안전 운행에 장애 요소가 된다. 그러므로 운전자는 이처럼 파손된 브레이드 러버를 다시 새것으로 교환해 주는 작업을 해야 하기 때문에 번거롭고 불편하였다. 아울러 그 교환 작업의 주기가 빨리 도달하는 등의 여러문제가 발생하였다.In other words, because the window cannot be properly cleaned, stains of the window remain in several places, which makes it difficult to secure the driver's vision, which is a barrier to safe driving. Therefore, the driver was troublesome and inconvenient because he had to work to replace the broken braid rubber with a new one again. In addition, several problems occurred such that the cycle of the exchange work reached quickly.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 본 발명은 목적은 브레이드 러버의 마모시 그 교환 주기를 반감시킴으로써 그 교환 작업에 따른 불편함을 해소함과 동시에 원가 절감의 효과를 얻을 수 있는 자동차용 와이퍼 브레이드를 제공하는 것이다.Therefore, the present invention is to solve the above problems, the object of the present invention is to reduce the inconvenience of the replacement work by reducing the replacement cycle when the wear of the braid rubber, and at the same time can reduce the cost of the automobile It is to provide a wiper braid.

Two flips 114 and 114a are formed.

상기 괘정구(120)에는, 상기 제1,2브레이드 러버(110)(110a)를 고정토록 제1, 2함실(122)(122a)을 형성하되 제1함실(122)의 저면에는 상기 제1플립(114)에 고정되게 제1삽지부(124)를, 제2함실(122a)의 측면에는 제2플립(114a)에 고정되게 제2삽지부(124a)를 형성하고, 정면 상측에는 삽지공(126)이 형성하여 된다.In the ruler 120, first and second compartments 122 and 122a are formed to fix the first and second blade rubbers 110 and 110a, but the first compartment 122 is formed on the bottom surface of the first compartment 122. The first inserting portion 124 is fixed to the flip 114, and the second inserting portion 124a is formed on the side of the second chamber 122a, and the second inserting portion 124a is fixed to the flip side 114a. 126 is formed.

상기 레버(13)에는, 일측단에 절곡부(132)를 하향 형성한 후 그 절곡부(132)에 사각공(134)을 형성하여 된다.In the lever 13, the bent portion 132 is formed downward at one end thereof, and then a square hole 134 is formed at the bent portion 132.

상기 사각핀(140)은, 상기 레버(130)의 사각공(134)을 통해 상기 괘정구(120)의 삽지공(126)에 고정 설치되게 한다.The square pin 140 is fixed to the insertion hole 126 of the ruler 120 through the square hole 134 of the lever 130.

이렇게 구성되는 본 발명의 설치 및 사용상태를 보면서 이에 따른 작용 효과를 상세히 설명한다.Looking at the installation and use of the present invention configured as described above will be described in detail the effects of the operation.

즉, 본 발명은 상기 괘정구(120)의 제1, 2함실(122)(122a)에 각각 상기 제1, 2브레이드 러버(110)(110a)를 삽설하고, 상기 레버(130)의 절곡부(132) 사각공(134)을 상기 괘정구(120)의 사각공(134)에 맞춘 상태에서 상기 삽지공(126)에 고정시키게 된다. 이때 상기 제1, 2브레이드 러버(110)(110a)는 서로 직각 방향으로 형성되어 있다.That is, the present invention inserts the first and second blade rubbers 110 and 110a into the first and second chambers 122 and 122a of the ruler 120, respectively, and the bent portion of the lever 130. (132) The square hole 134 is fixed to the insertion hole 126 in a state in which the square hole 134 of the ruler 120 is fitted. In this case, the first and second braid rubbers 110 and 110a are formed at right angles to each other.

이렇게 설치된 상태에서 그 사용 상태를 살펴보면, 우선 전원을 온시켜 와이퍼 브레이드를 동작시킨다. 즉, 그 와이퍼 브레이드의 제1브레이드 러버(110)가 상기 윈드시일드에 접촉된 상태에서 좌우로 회전을 반복하게 되면, 윈드시일드에 맺힌 눈이나 빗물 따위를 제거하게 되어 운전자의 시야를 양호하게 확보할 수 있게 되는 것이다.Looking at the state of use in this state of installation, first turn on the power to operate the wiper braid. That is, if the first blade rubber 110 of the wiper blade is rotated from side to side in contact with the windshield, the snow or rain water formed on the windshield is removed to improve the driver's vision. It will be secured.

이러한 동작으로 장기간 사용하게 되면, 상기 제1브레이드 러버(110)는 마모되어 윈드시일드에 맺힌 눈 따위를 제대로 제거할 수 없게 되므로, 운전자의 시야 확보에 불리한 경우가 생기게 된다.When used for a long time in this operation, the first braid rubber 110 is worn and can not properly remove the snow formed on the windshield, it is disadvantageous to secure the driver's vision.

이때, 상기와 같이 고정된 사각핀(140)을 빼내게 되면, 상기 괘정구(120)가 움직일 수 있는 상태로 된다. 그러면 운전자는 상기 괘정구(120)를 회동시켜 사용되지 않은 제2브레이브 러버(110a)를 상기 윈드시일드에 접촉된 상태로 위치시킨 후 상기와 같이 빼냈던 사각핀(140)을 상기 레버(130)의 사각공(134)을 통해 괘정구(120)의 삽지공(126)에 삽입 고정하게 된다. 이 상태로 다시 윈드시일드에 맺힌 눈 따위의 제거 작업을 수행할 수 있게 된다. 이와 같이 마모된 제1브레이드 러버(110)의 교환 작업을 일단 생략해도 되는 것이다.At this time, when the fixed square pin 140 is pulled out as described above, the ruler 120 becomes movable. Then, the driver rotates the ruler 120 to position the unused second brake rubber 110a in contact with the windshield, and then removes the square pin 140 that was removed as described above. It is inserted into the insertion hole 126 of the ruler 120 through the square hole 134 of the). In this state, it is possible to perform the removal of snow on the windshield again. The replacement work of the worn first braid rubber 110 may be omitted once.

이후 상기 제2브레이드 러버(110a)도 마모되었을 경우 상기 제1브레이드 러버(110)와 함께 새것으로 교환해 주면 되는 것이다.After the second blade rubber (110a) is also worn when the replacement with the first blade rubber 110 to a new one.

이상에서 상세히 설명한 것과 같이 본 발명 자동차용 와이퍼 브레이드에 따르면, 직각 방향으로 회동될 수 있는 제1,2브레이드 고무를 함께 설치하였으므로, 그 교환 주기를 반감시킬 수 있게 됨에 따라 작업을 간단하게 할 수 있는 동시에 원가 절감의 효과를 갖게 되는 매우 유용한 발명이다.According to the wiper braid for the present invention as described in detail above, since the first and second braid rubbers that can be rotated in a right angle direction are installed together, the replacement cycle can be reduced by half so that the work can be simplified. At the same time, it is a very useful invention that has the effect of cost reduction.
