본 고안은 TV의 전면에 설치되어 화면의 크기를 임의로 용이하게 확대 또는 축소시켜 시청할 수 있도록 구성된 TV화면용 배율렌즈의 인출거리조정장치에 관한 것이다.The present invention relates to a drawing distance adjusting apparatus for a magnification lens for a TV screen, which is installed on the front of the TV and configured to easily enlarge or reduce the size of the screen.

이러한 기술과 관련하여 종래에도 TV의 화면 전방부에 일정거리를 이격시켜 확대경을 설치한 것이 있었으나 이는 그 이격된 상태로 고정되어 있기 때문에 시청자에게 알맞는 화면크기를 임으로 조정할 수가 없어 불편하였다.In the related art, there has been a case in which magnifiers are installed at a predetermined distance from the front of the screen of the TV. However, since it is fixed in the spaced apart state, the screen size suitable for the viewer cannot be arbitrarily adjusted.

그리하여 국내 실용신안공고 제88-320호에서는 좌, 우 수직간의 하단에 고리를 착설하고 좌우양단에 절곡부를 형성하며 내측의 단간은 리벨로 유착한 조절간의 좌우양단의 공간에 수평간을 유삽하고 리벨로서 각각 유착하여 TV밑에 수평간을 깔게 구성한 TV확대경 착설장치를 제공하여 조절간이 꺽이면서 인출되도록 한 것이 있었으나 이는 그 구조가 복잡하고 시청자가 손으로 힘을 가해 일일히 조정해야만 하기 때문에 번거로워 한번 맞추고 나면 그 상태를 계속유지하여 시청하게 되므로 시청자에게 알맞는 화면크기를 그때 그때 용이하게 맞추어 줄수가 없어 결국 종래의 불편함은 해소될 수가 없었다.Thus, in Korean Utility Model Publication No. 88-320, a ring is installed at the bottom of the left and right vertical sides, and bent parts are formed at the left and right ends. As a result, there was a TV magnifier installation device, which was constructed to be horizontally installed under the TV, so that it could be pulled out by adjusting the angle between them. Since the state is continuously maintained, the screen size suitable for the viewer cannot be easily adjusted at that time, and thus, the conventional inconvenience cannot be solved.

본 고안은 이와같은 종래기술이 갖는 제반 문제점과 불편함을 해소하고 개선하기 위하여 안출된 것으로 그 목적은 TV화면의 크기를 시청자가 임의로 용이하게 확대 또는 축소시켜 시청할 수 있도록 구성된 TV화면용 배율렌즈의 인출조정장치를 제공함에 있다.The present invention was devised to solve and improve all the problems and inconveniences of the prior art. The purpose of the present invention is to provide a magnification lens for a TV screen configured to allow viewers to easily enlarge or reduce the size of the TV screen. It is to provide a withdrawal adjustment device.

본 고안의 다른 목적은 상기한 배율렌즈를 TV에서 발생되는 유해전자파를 차단 시킬수 있는 재질로 구성하여 화면의 확대기능은 물론이거니와 TV에서 발생되는 유해전자파를 동시에 제거할 수 있도록 하고자 하는데 있다.Another object of the present invention is to configure the above-mentioned magnification lens with a material capable of blocking harmful electromagnetic waves generated from a TV, and to remove the harmful electromagnetic waves generated from the TV at the same time.

본 고안의 또 다른 목적은 상기한 배율렌즈에 의해 배시되는 TV화면이 확대되어짐으로 TV화면을 대형화 하지 않아도 되어 결국 전력의 소모를 감소시키고자 하는데 있다.Still another object of the present invention is to reduce the power consumption by not having to enlarge the TV screen because the TV screen is enlarged by the magnification lens.

이하 첨부된 도면에 의거하여 이를 좀더 상세히 설명하면 명백해질것이다.It will be apparent from the following detailed description based on the accompanying drawings.

즉, 본 고안은 첨부된 도면 제1도 및 제2도에서 보여주는 바와같이 TV(1)의 전면에는 상부양측에 안내공(11)과 하부양측에 사각공(12)이 각각 형성되고 상기 사각공(12)과 일치되는 TV(1)의 내부에 피니언기어(13)가 축설된 모터(M)를 설치하며 상기 안내공 (11)과 사각공(12)에는 배율렌즈(2)가 끼워진 보강테(21)의 상단양측과 하단양측에 각각 고정설치된 일정길이를 갖는 안내간(22)과 래크기어(23)가 유동가능하게 끼워지되, 상기 래크기어(23)는 TV(1)의 내부에 설치된 구동모터(M)에 축설된 피니언기어(13)와 치합되어 이루어진다.That is, the present invention, as shown in the accompanying drawings, Figs. 1 and 2, the front of the TV (1) is formed with a guide hole 11 on the upper both sides and a square hole 12 on the lower both sides, respectively, the square hole A reinforcing frame having a magnification lens 2 fitted into the guide hole 11 and the square hole 12 is provided with a motor M in which the pinion gear 13 is arranged in the inside of the TV 1 corresponding to 12. Guide racks 22 and rack gears 23 having fixed lengths fixed to the upper and lower sides and the lower sides of the 21, respectively, are fitted to be movable, and the rack gears 23 are inside the TV 1. It is made to mesh with the pinion gear (13) built in the drive motor (M) installed in.

이와같은 구조로 이루어진 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of such a structure as follows.

먼저 상기한 구동모터(M)의 on/off스위치(미도시)를 TV의 조작스위치나 리모콘장치(미도시)에 연결시켜 원격조정이나 스위치조작이 가능하게 한다.First, the on / off switch (not shown) of the driving motor (M) is connected to a TV operation switch or a remote control device (not shown) to enable remote control or switch operation.

이러한 상태로 TV(1)화면의 크기를 확대시키고자 할 경우 리모콘에 의한 원격조정이나 스위치조작을 하여 상기 모터(M)를 일측으로 구동시켜 주게되면 상기 모터(M)에 축설된 피니언기어(13)가 배율렌즈(2)가 끼워진 보강테(21)에 결합된 래크기어(23)와 치합되어 있으므로 그 구동력에 의해 상기 배율렌즈(2)가 TV(1)의 전방으로 인출되면서 배율렌즈(2)에 배시되는 TV화면의 영상이 확대되어지게 된다.In this state, when the size of the TV (1) screen is to be enlarged, the remote control or the switch operation by the remote control drive the motor (M) to one side, and the pinion gear (13) built up in the motor (M) ) Is engaged with the rack gear 23 coupled to the reinforcing frame 21 in which the magnification lens 2 is fitted, and the magnification lens 2 is drawn out in front of the TV 1 by the driving force. The video of the TV screen displayed in 2) is enlarged.

이와는 반대로 TV화면을 축소시켜 시청하고자 할 경우에는 상기 모터(M)를 역회전시켜 상기 래크기어(23)를 TV(1)의 내부로 수장케함으로써 인출되었던 배율렌즈(2)를 화면에 가깝게 끌어들여 상기 배율렌즈(2)에 배시되는 TV화면의 영상을 축소케하여 시청하면 된다.On the contrary, when the TV screen is to be reduced and watched, the motor M is rotated in reverse to allow the rack gear 23 to be stored inside the TV 1 so that the magnification lens 2 drawn out close to the screen. It may be used to reduce and view the image of the TV screen arranged by the magnification lens 2.

이와같은 본 고안에 의하면 TV화면을 시청자가 임의의 적절한 크기로 용이하게 조절하여 시청할 수 있게 함으로써 시청자에게 유용한 편리성을 제공하여 주는 한편, 유해전자파를 차단하고 또한 TV화면의 크기를 대형화할 필요가 없어 소모전력의 절감효과도 아울러 거둘수 있는 매우 유익한 고안임이 명백하다.According to the present invention, it is necessary to provide a convenient convenience to the viewer by allowing the viewer to easily watch and adjust the TV screen to any appropriate size, while preventing harmful electromagnetic waves and increasing the size of the TV screen. It is obvious that this is a very beneficial design that can save power consumption as well.
