Description

자동차용 와이퍼{a wiper for vehicles}Wiper for vehicles {a wiper for vehicles}

본 발명은 자동차용 와이퍼에 관한 것으로, 특히 블레이드의 재사용이 가능해짐으로써 블레이드 교체비용의 절감을 도모할 수 있도록 된 자동차용 와이퍼에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile wiper, and more particularly, to an automobile wiper that enables reduction of blade replacement costs by allowing a blade to be reused.

일반적으로 자동차의 전면 유리창인 윈드쉴드글래스에는 모터로 작동되는 와이퍼가 구비되어, 비가올 때 윈드쉴드글래스 면에 묻은 물방울을 닦아 줌으로써 운전자의 시야를 확보하여 안전운행을 할 수 있도록 되어 있다.In general, the windshield glass, which is the windshield of the car, is provided with a motor-driven wiper, so as to clean the water droplets on the surface of the windshield glass when it rains to secure the driver's vision and to drive safely.

상기 와이퍼는 고정(설치)점을 중심으로 회동되는 아암과, 이 아암에 중심부가 고정되는 카트리지와, 이 카트리지에 끼워지고 유리면에 직접 접촉되어 유리면의 물방울을 쓸어내리는 고무재질의 블레이드로 이루어져 있다.The wiper is composed of an arm pivoted about a fixed (installation) point, a cartridge fixed to the center of the arm, and a rubber blade inserted into the cartridge and directly in contact with the glass surface to wipe off water droplets on the glass surface.

따라서, 운전자가 실내에서 와이퍼스위치를 on시키면, 모터가 작동되어 상기 아암이 설정범위내에서 부분회동(왕복)되고, 이때 카트리지에 끼워진 블레이드가 윈드쉴드글래스에 묻은 물방울을 제거하여 운전자의 시야를 확보할 수 있게 된다.Therefore, when the driver turns on the wiper switch indoors, the motor is operated to rotate the arm partially within the set range, and the blade inserted in the cartridge removes water droplets on the windshield glass to secure the driver's vision. You can do it.

한편, 상기 블레이드에는 립이 형성되어 있어서, 이 립이 윈드쉴드글래스면에 직접 닿은 상태에서 이동됨으로써 와이핑작용을 하게 되는데, 이 립이 닳으면 윈드쉴드글래스면에서 물방울을 닦아내는 작용이 제대로 이루어지지 않으므로 블레이드를 교환해야만 한다.On the other hand, the blade is formed with a lip, the lip is moved in direct contact with the windshield glass surface to perform a wiping action, when this lip worn wears the action to wipe the water droplets on the windshield glass surface properly The blade must be replaced because it is not supported.

즉, 종래 와이퍼의 블레이드에는 상기 립이 하나만 형성되어 있기 때문에(메인립의 양측에 보조립이 형성된 형식의 것도 있으나, 보조립은 고려하지 않는다.) 블레이드의 사용이 1회에 한정되므로 블레이드의 교환비용이 증가되는 문제점이 있었다.That is, since only one lip is formed in the blade of the conventional wiper (although there is a type in which the auxiliary lip is formed on both sides of the main lip, the auxiliary lip is not considered). Since the use of the blade is limited to one time, the blade is replaced. There was a problem that the cost is increased.

또한, 블레이드 교체시기가 임박하였을 때 갑자기 집중 호우를 만나게 되면, 와이핑작용이 원활하게 이루어지지 않으므로 전방시야를 제대로 확보할 수 없어서 안전운행에도 지장을 주게 되는 문제점이 있었다.In addition, when suddenly meets the heavy rain when the blade replacement time is imminent, the wiping action is not made smoothly, there is a problem that can not secure the front view properly, also interfere with the safe operation.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 블레이드를 재사용할 수 있게 됨으로써 블레이드 교체비용을 절감할 수 있고, 호우에도 즉시 대처할 수 있도록 된 자동차용 와이퍼를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, and the object of the present invention is to provide a wiper for an automobile that can reduce blade replacement costs by being able to reuse blades and immediately cope with heavy rain.

상기와 같은 목적을 달성하기 위한 본 발명은, 카트리지에 정면돌기와 상하면고정단 및 측면고정단이 형성되고, 이 정면돌기와 상하면고정단 및 측면고정단이 끼워지는 구멍 및 홈이 블레이드에 형성되어, 블레이드가 카트리지에 조립되며, 블레이드는 4각 단면으로 형성되되, 4모서리에 각각 립이 형성된 구조로 이루어져 있다.The present invention for achieving the above object, the front projection and the upper and lower fixed end and the side fixed end is formed in the cartridge, the front projection and the upper and lower fixed end and the side fixed end is formed in the blade hole and groove is formed in the blade, the blade Is assembled to the cartridge, the blade is formed in a four-sided cross section, it consists of a structure in which the ribs are formed on each of four corners.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 자동차용 와이퍼의 분해 사시도로서, 본 발명의 카트리지(1)는 블레이드(5) 취부면의 중앙과 양 측부에 4각으로 돌출된 정면돌기(2)들이 형성되고, 이 정면돌기(2)들의 형성위치와 동일선상의 상하부면에 상호 마주 보는 방향으로 절곡돌출된 상하면고정단(3)들이 형성되며, 양측단부에도 서로 마주보도록 안쪽으로 절곡돌출된 측면고정단(4)들이 형성된 형상으로 되어 있다.1 is an exploded perspective view of an automobile wiper according to the present invention, the cartridge (1) of the present invention is formed with a front projection (2) protruding in a square at both the center and both sides of the mounting surface of the blade (5), The upper and lower fixed ends 3, which are bent and protruded in the direction facing each other, are formed on the upper and lower surfaces on the same line as the formation positions of the front protrusions 2, and the side fixed ends 4 which are bent inwardly so as to face each other at both end portions thereof. The shape is formed.

그리고, 상기 카트리지(1)에 취부되는 블레이드(5)는 정사각 단면의 세장부재로서, 상기 정면돌기(2)와 상하면고정단(3)들의 대응위치인 중앙과 양 측부에 서로 교차관통되는 구멍(6,7)들이 형성되고, 양측단부에는 각각 4각의 홈(8)이 형성된 형상으로 되어 있다.In addition, the blade 5 mounted on the cartridge 1 is an elongated member having a square cross-section, and a hole that crosses each other at the center and both side portions corresponding to the front projections 2 and the upper and lower fixed ends 3. 6 and 7 are formed, and each side end part has the shape in which the square groove 8 was formed, respectively.

따라서, 상기 정면돌기(2)와 상하면고정단(3)들이 구멍(6,7)에 끼워지고, 측면고정단(4)이 홈(8)에 끼워지는 상태로 블레이드(5)가 카트리지(1)에 안정적으로장착되게 된다.Accordingly, the blade 5 is inserted into the cartridge 1 with the front protrusion 2 and the upper and lower fixing ends 3 fitted into the holes 6 and 7, and the side fixing ends 4 fitted into the grooves 8. ) Will be mounted stably.

그 장착상태의 단면은 도 2와 같은 바, 즉 블레이드(5)의 4면중 어느 한면에 형성된 구멍(도면에서는 7)에 카트리지(1)의 정면돌기(2)가 삽입되고, 이 정면돌기(2)가 삽입된 구멍의 상하측면에 형성된 구멍(6)으로 상기 상하면고정단(4)들이 끼워지는 상태가 된다. 여기서, 상기 정면돌기(2)는 상하면고정단(4)에 비해 길게 형성되어 있어서 구멍(6,7)들이 서로 교차된 부분을 지나 블레이드(5)의 글래스대응면측까지 끼워지며, 상하면고정단(4)들은 점선으로 도시된 바와 같이 유동적이어서 블레이드(5)를 끼워 넣는데 불편함이 없도록 되어 있다.The cross section of the mounting state is the same as that of Fig. 2, i.e., the front projection 2 of the cartridge 1 is inserted into a hole (7 in the drawing) formed on one of four surfaces of the blade 5, and the front projection 2 The upper and lower fixed ends 4 are inserted into the holes 6 formed on the upper and lower sides of the holes into which the holes are inserted. Here, the front projection (2) is formed longer than the upper and lower fixed ends (4) so that the holes (6,7) are fitted to the glass corresponding surface side of the blade (5) through the intersection of each other, the upper and lower fixed ends ( 4) are fluid as shown by the dotted line so that there is no inconvenience in fitting the blade 5.

또한, 상기 블레이드(5)에는 도 3에 도시된 바와 같이, 4 모서리 부위에 모두 립(5a)이 형성되어 있다.In addition, as shown in FIG. 3, the blade 5 is formed with ribs 5a at all four corners.

따라서, 최초 장착상태에서 윈드쉴드글래스면에 접촉되어 있던 립의 수명이 다하면, 블레이드(5)를 탈거후 90° 회전장착시켜 새로운 립이 윈드쉴드글래스면에 닿게 함으로써 종래 블레이드를 교체한 것과 같은 효과를 볼 수 있다.Therefore, when the life of the lip that was in contact with the windshield glass surface at the time of initial installation is expired, the blade 5 is removed and rotated by 90 ° so that the new lip touches the windshield glass surface. Can be seen.

이와 같이 하나의 립이 수명을 다하였을 때 블레이드를 90° 회전시켜 재장착하여 사용할 수 있게 됨으로써 하나의 블레이드를 여러 차례 반복 사용할 수 있게 되므로, 블레이드 교환에 따른 비용의 지출을 감소시킬 수 있게 된다.As such, when one lip reaches the end of its life, the blade can be rotated by 90 ° to be refitted so that one blade can be repeatedly used, thereby reducing the cost of blade replacement.

또한, 종래에는 립이 닳아서 블레이드 교체시기가 되었으나 미처 블레이드를교체하지 못한 상태에서 호우를 만나게 되면 와이핑작용이 제대로 이루어지지 않아 전방시야를 원활히 확보할 수 없으므로 안전운행에 지장이 있었으나, 본 발명에 따른 블레이드를 사용하면 즉시 블레이드를 90°회전장착하여 새 립이 와이핑작용을 할 수 있게 됨으로써 양호한 상태의 전방시야를 확보할 수 있게 되어 안전운행에 도움이 된다.In addition, in the past, the lip was worn out to replace the blades, but when encountering heavy rain in the state of not replacing the blade, the wiping action is not made properly, so that it is difficult to secure the front view, but in the present invention, there is a problem in the safe operation. By using the blade accordingly, the blade can be rotated 90 ° immediately so that the new lip can be wiped to secure a good forward field of view, helping to drive safely.

이상 설명한 바와 같이 본 발명에 따르면, 하나의 블레이드를 반복하여 재사용할 수 있으므로 블레이드교체에 따른 비용을 절감할 수 있고, 또한 윈드쉴드글래스면에 접촉한 립이 닳은 상태에서 호우를 만나도 즉시 새로운 립을 윈드쉴드글래스면에 접촉시켜 사용할 수 있으므로 블레이드 미교체로 인한 호우시의 전방시야 확보문제를 해결할 수 있게 되는 효과가 있다.As described above, according to the present invention, a single blade can be repeatedly reused, thereby reducing the cost of replacing the blade, and also creating a new lip immediately after encountering heavy rain in a state where the lip in contact with the windshield glass is worn out. Since it can be used in contact with the windshield glass surface, there is an effect that can solve the problem of securing the front field of view in case of heavy rain due to the replacement of the blade.
