본 고안은 합성수지로 제조된 원형 하우징내에 필터판을 삽입한 카메라용 필터에 관한 것이다.The present invention relates to a filter for a camera in which the filter plate is inserted into a circular housing made of synthetic resin.
종래의 카메라용 필터하우징은 주로 알루미늄 또는 황동등의 금속으로 제조되며, 그 구조는 제1도에 도시되어 있다. 원형하우징(1)의 후단 즉, 카메라 경통의 선단에 부착되는 부분에 내측으로 돌출되고 외주면에는 나사가 형성된 돌출부(2)를 형성하고 그로써 필터판(3)의 외주부근을 접촉시키고 상기 원형하우징의 내부에 나사 결합시킨 지지링(4)으로 압착시키거나, 또는 제2도에 도시한 바와같이 원형하우징(1)의 후단에 형성한 내측돌출부(2)의 인접하방에 2단 요홈을 형성하여 그 하단부에 필터판(3)을 삽입시컴과 동시에, 상기 요홈에 횡단면이 원형인 가벼운 탄성분할링(6)을 끼워맞추어 필터판을 누르도록 구성되어 있었다.The conventional filter housing for a camera is mainly made of a metal such as aluminum or brass, the structure of which is shown in FIG. On the rear end of the circular housing 1, i.e., the portion attached to the front end of the camera barrel, an inwardly protruding portion 2 is formed on the outer circumferential surface thereof, whereby the outer peripheral portion of the filter plate 3 is brought into contact with each other. It is pressed with a support ring 4 screwed inside, or as shown in FIG. 2, a two-stage groove is formed below the inner protrusion 2 formed at the rear end of the circular housing 1, and At the same time as inserting the filter plate 3 into the lower end portion, a light elastic split ring 6 having a circular cross section was fitted in the groove to press the filter plate.
그러나, 상기와 같은 카메라용 필터는 그 하우징이 금속으로 되어 있기 때문에 무거우며, 하우징 부품을 제조할때는 주로 절삭가공을 하게되므로 많은 공정을 거쳐야 하고, 따라서 제조비가 많이 들었다. 또 상기와 같은 구성으로 하기 때문에 조립과정을 자동화하기 어려우며 사람의 손을 필요로 하였다.However, the camera filter as described above is heavy because the housing is made of metal, and when the housing parts are manufactured, the cutting process is mainly performed, so a lot of processes are required, and thus, manufacturing costs are high. In addition, since the configuration as described above it is difficult to automate the assembly process and required a human hand.
그런데 상기 카메라용 필터하우징을 합성수지재료로 형성하면 전체중량이 감소되고 하우징 부품도 프레스로 성형할 수 있으므로 제조비가 적게되어, 상기와 같은점에 착안하여 최근에는 합성수지 하우징을 갖는 카메라용 필터를 제3도에 도시한 바와같이 제조하고 있다. 즉 원형하우징(1)의 상단부에 돌출부(2)를 형성하고, 돌출부(2)의 내면에 쐐기모양의 돌출부(7)를 형성하여 필터판(3)을 상기 돌출부(7)의 압력으로 탄성 변형시켜 필터하우징(1)에 강제로 끼워맞춘다. 또 제4도에 도시한 바와같이 원형하우징(1)의 상단부에 돌출부(2)를 형성하고, 필터판(3)을 돌출부(2)와 원형하우징(1)의 내면에 형성시킨 플랜지(8)에 접착제(9)등으로 접착한 것도 공지되어 있다.However, when the filter housing for the camera is formed of a synthetic resin material, the total weight is reduced and the housing parts can be molded by a press, thereby reducing the manufacturing cost. In view of the above, a camera filter having a synthetic resin housing has been recently manufactured. It manufactures as shown in FIG. That is, the protrusion 2 is formed at the upper end of the circular housing 1, and the wedge-shaped protrusion 7 is formed on the inner surface of the protrusion 2 so that the filter plate 3 is elastically deformed by the pressure of the protrusion 7. To the filter housing 1 by force. In addition, as shown in FIG. 4, a flange 8 is formed on the upper end of the circular housing 1, and the filter plate 3 is formed on the inner surface of the protrusion 2 and the circular housing 1. As shown in FIG. It is also known to adhere to an adhesive 9 or the like.
상기 제3도의 경우에는 필터판이 원형하우징에 완전 밀착시키기 어렵고, 원형하우징(1)에 필터판(3)을 강제로 끼워맞춘 경우 필터판(3)이 돌출부(7)를 손상시켜 외관을 해치는 단점이 있다. 또, 제4도의 경우는 필터판(3)을 유리로 제조하는 경우, 원형하우징(1)과의 팽창율의 차이로 필터판(3)이 떨어지는 경우가 있고 상기 접착제가 접착면으로 부터 흘러나와 외관을 심하게 해치는 경우가 많다.In the case of FIG. 3, the filter plate is difficult to completely adhere to the circular housing, and when the filter plate 3 is forcibly fitted to the circular housing 1, the filter plate 3 damages the protruding portion 7 to impair the appearance. There is this. In the case of FIG. 4, when the filter plate 3 is made of glass, the filter plate 3 may fall due to a difference in expansion ratio from the circular housing 1, and the adhesive flows out from the adhesive surface. Often hurts badly.
본 고안은 상기와 같은 단점을 제거한 것으로, 제1목적은 합성수지 하우징을 갖고 자동 조립할 수 있는 카메라용 필터를 제공하는 것이다. 제2목적은 필터판을 하우징에 접착시키면서 접착부위과 외관으로 보아 접착시키지 않은 것처럼 조립하여 외관이 매우 양호한 합성수지 하우징을 갖는 카메라용 필터를 제공하는 것이다. 또 제3목적은 필터판의 두께가 변화해도 동일 부품으로 조립할 수 있는 합성수지 하우징을 갖는 카메라용 필터를 제공하는 것이다. 제4목적은 보다 강한 접착을 할수 있는 합성수지 하우징을 갖는 카메라용 필터를 제공하는 것이다.The present invention is to eliminate the above disadvantages, the first object is to provide a filter for a camera that can be assembled automatically with a synthetic resin housing. A second object is to provide a filter for a camera having a synthetic resin housing having a very good appearance by assembling the filter plate to the housing and assembling the filter plate as if it is not bonded in appearance. A third object is to provide a camera filter having a synthetic resin housing which can be assembled into the same component even if the thickness of the filter plate changes. A fourth object is to provide a filter for a camera having a synthetic resin housing capable of stronger adhesion.
즉, 본 고안은 카메라용 필터의 원형하우징을 피사체 방향으로 암나사를 구비한 전방부(도면상으로는 하방)와 카메라 선단에 맞추어지는 수나사를 구비한 후방부(도면상으로는 상방)로 분할하고 또 상기 하우징의 전방부와 후방부 사이에 필터판을 삽이하고 전방부와 후방부의 접착면의 적어도 한쪽에 요철을 형성하여 상기 양 원형하우징을 서로 초음파 접착하여 일체로 고정한 것을 특징으로 하는 새로운 카메라용 필터인 것이다.That is, the present invention divides the circular housing of the filter for the camera into a front part (downward in the drawing) with a female screw in the direction of the subject and a rear part (upward in the drawing) with a male screw fitted to the tip of the camera. It is a new camera filter, characterized in that the filter plate is inserted between the front part and the rear part and irregularities are formed on at least one of the adhesive surfaces of the front part and the rear part so that the two circular housings are ultrasonically bonded to each other and fixed together. .
이하, 본 고안의 실시예를 첨부도면을 참조하여 구체적으로 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제5도에 도시한 바와같이, 카메라용 필터의 합성수지 원형하우징을 카메라 경통의 선단부에 설치하게되는 수나사를 구비한 후단부(11)와 피사체측으로 암나사를 구비한 전방부(12)로 분할하여 그 사이에 필터판(13)를 협착하고, 또 상기 전방부(12)와 후단부(11)의 상기 접착면(14)을 접착시킨다.As shown in FIG. 5, the synthetic resin circular housing of the camera filter is divided into a rear end portion 11 having a male screw to be installed at the tip end of the camera barrel and a front portion 12 having a female screw on the subject side. The filter plate 13 is clamped in between, and the adhesion surface 14 of the front part 12 and the rear end part 11 are adhere | attached.
이와같이 본 고안에서는 원형하우징의 전방부 및 후방부의 형상이 단순하기 때문에 원형하우징 부품을 용이하게 프레스 성형할 수 있으며 또 접착면이 내부에 숨겨지기 때문에 접착부분이 미려해지고 외관상 좋게 보인다. 접착은 통상적인 접착제를 사용할 수도 있으나 초음파를 사용하면 더욱 강력히 접착할 수 있으며 자동 조립하기도 쉬운 잇점이 있다.Thus, in the present invention, since the front and rear parts of the circular housing are simple, the circular housing part can be easily press-molded, and the adhesive part is hidden inside, so that the adhesive part is beautiful and looks good. Adhesion may use conventional adhesives, but ultrasonics can be used for stronger bonding and automatic assembly.
제6도는 제5도에 도시한 원형하우징의 접착면에 치차모양의 요철(15,15')을 형성한 것이다.6 shows tooth-shaped irregularities 15 and 15 'formed on the adhesive surface of the circular housing shown in FIG.
일반적으로 초음파로 접착부를 용융하여 접착하는 경우 초음파가 강하게 통과하면 잔여 용융물이 발생하는데 이는 요부(15')에 남게되어 외부로 비어져 나오는 것을 방지할 수 있다. 또 상기 요철은 필터판(13)의 두께가 변화해도 원형하우징 부품의 치수를 변화시키지 않는 장점이 있다. 즉 필터판의 두께가 두꺼우면 철부의 용융량을 적게해도 좋고 필터판이 얇으면 철부의 용융량을 많게하여 잔여 용융물을 요부(15')에 유입시켜 외측에는 새어나오지 않도록 조작할 수 있다.In general, in the case of melting and adhering the adhesive part with ultrasonic waves, when the ultrasonic waves pass strongly, residual melt is generated, which may be left in the recessed part 15 ′, thereby preventing it from protruding to the outside. In addition, the unevenness has an advantage of not changing the dimensions of the circular housing part even if the thickness of the filter plate 13 changes. That is, if the thickness of the filter plate is thick, the melting amount of the convex portion may be reduced. If the filter plate is thin, the melting amount of the convex portion may be increased so that the remaining melt flows into the recessed portion 15 'so as not to leak out.
제7도는 원형하우징 후방부(11)와 전방부(12) 사이에 필터판(13)을 협착하여 후방부(11)를 전방부(12)에 나사 결합시킨 후 이를 접착한 경우를 도시한다. 이 실시예에서는 후방부(11)와 전방부(12)를 나사(16)로 결합한 후 접착시키기 때문에 극히 강하게 접착할 수 있으나 통상적으로 사용할때는 이 정도로 강력하게 접착할 필요는 없다. 그러나 특수필터를 사용하는 경우에 유용하다. 이상에 설명한 바와같이 본 고안에 따른 카메라용 필터는 원형하우징을 합성수지로 구성하고 또 상기 원형하우징을 전방부(12)와 후방부(11)로 분할하여 그 접착면에 요철(15,15')을 형성하고, 상기 전방부 및 후방부 사이에 필터판을 협착하고 전방부 및 후방부를 초음파 접착시킨 것으로 되어있기 때문에 조립할때 종래의 손작업도 필요하지 않고 자동 조립할 수 있을뿐 아니라 접착부분이 숨겨지므로 외부에서 알아볼 수 없으며 필터판의 두께가 변화해도 동일부품을 적용할 수 있다.FIG. 7 illustrates a case in which the filter plate 13 is squeezed between the circular housing rear part 11 and the front part 12 to screw the rear part 11 to the front part 12 and then bonded thereto. In this embodiment, since the rear part 11 and the front part 12 are bonded with the screw 16 and then bonded, they can be extremely strongly adhered, but they do not need to be strongly adhered to this extent in normal use. However, it is useful when using special filters. As described above, the camera filter according to the present invention comprises a circular housing made of synthetic resin, and the circular housing is divided into a front part 12 and a rear part 11 to have irregularities on the adhesive surface (15, 15 '). Since the filter plate is squeezed between the front part and the rear part and ultrasonically bonded to the front part and the rear part, conventional hand work is not required when assembling and the automatic assembly can be done, as well as the adhesive part is hidden. The same parts can be applied even if the thickness of the filter plate changes.
이상 본 고안에 따르면 초음파 접착법을 사용할 수 있게되어 접착강도도 높아지고 자동조립하기도 편리하고 가벼운 카메라용 필터를 제공한 것으로 그 효과가 우수하다.According to the present invention, it is possible to use the ultrasonic bonding method, so that the adhesive strength is increased, and the automatic filter is easy to be assembled and provides a light filter for the camera.
