본 고안은 액정 프로젝터에서 스크린에 화면을 정확히 맞추기 위해 높낮이를 조절하는 액정 프로젝터의 높낮이 조절장치에 관한 것이다.The present invention relates to a height adjustment device of a liquid crystal projector for adjusting the height to accurately fit the screen on the screen in the liquid crystal projector.

액정 프로젝터는 제품의 특성상 스크린에 화면이 조금만 어긋나도 화상이 기울게 되므로 스크린에 화면을 정확히 맞추어야만 한다.LCD projectors must be correctly aligned to the screen because the image is tilted even if the screen is slightly displaced on the screen due to the characteristics of the product.

종래 액정 프로젝터의 높이 조절장치는 제3도에서와 같이 제품밑판(3)에 풋트홀더(2)를 스크류(7)로 나사식 고정시킨후 하측에서 풋트(1')를 풋트홀더(2)에 나사식 삽입시켜 상측에서 너트(8)로 고정시킴으로서 구성이 완료되는 것으로 스크린에 화면을 일치시키기 위해서는 풋트를 회전시키면 풋트와 풋트홀더의 나사 결합에 의해 세트가 상, 하로 이동되는 것이나 풋트의 회전시 바닥면과 밀착되어 많은 저항을 받아 회전 원심력이 작용되므로 세트기 좌, 우로 이동되는 결점이 있어 화면을 정확히 일치시킬수 없으며 이를 방지하기 위해서는 세트를 들고 풋트를 회전시켜야 하나 이 역시 세트를 자주 들었다 놓았다 해야함으로 동작이 불편한 결점을 발생한다.Conventionally, the height adjusting device of the liquid crystal projector has screwed the foot holder 2 on the product base plate 3 with the screw 7 as shown in FIG. 3, and then puts the foot 1 'on the foot holder 2 from the lower side. The configuration is completed by screwing the nut into the upper part and fixing it with the nut (8). To match the screen on the screen, rotate the foot to move the set up and down by screwing the foot and the foot holder, or during the rotation of the foot. Since the centrifugal force is applied due to the resistance to the bottom surface, and the rotation centrifugal force is applied, there is a flaw moving to the left and right of the set, so that the screen cannot be exactly matched. To prevent this, the set must be lifted and the foot rotated. As a result, the operation is inconvenient.

따라서 본 고안은 이와같은 종래의 결점을 해소시키기 위하여 안출된 것으로 바닥면과 많은 저항을 받도록 하여 세트의 높이 조절시 좌, 우의 이동이 없이 보올의 구름운동으로 높낮이만 자유로이 조절되도록 함을 목적으로 한다.Therefore, the present invention is designed to solve the above-mentioned drawbacks, so that it receives a lot of resistance with the bottom surface, so that the height of the set can be adjusted freely only by the cloud movement of the bowl without moving left and right. .

이와같은 목적을 갖는 본 고안은 풋트핸들과 홀더핸들의 나사작용으로 제품의 다리부위가 상하로 움직이며 높이가 조절되고 이때의 회전으로 인한 제품의 이동을 방지하기 위하여 풋트의 하측으로 쿠션을 정착하는 동시에 풋트핸들과 풋트사이에 풋트핸들의 회전시 구름운동으로 제품의 이동이 없이 높낮이만 조절되는 보올을 형성시키는 것이다.The present invention having this purpose is to fix the cushion to the lower side of the foot in order to prevent the movement of the product due to the height of the leg portion of the product is moved up and down by the screw action of the foot handle and the holder handle At the same time, the rolling motion of the foot handle between the foot handle and the foot forms a bowl that is controlled only by height without moving the product.

이하 본 고안을 첨부시킨 도면에 의하여 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

홀더 삽입공(3a)과 나사공(3b)이 형성되는 제품밑판(3)과 상기 홀더삽입공(3a)에 삽입되며 스크류(7)로서 제품밑판(3)에 고정되는 삽입공(2b)과 내주면의 나사(2a)를 갖는 홀더핸들(2)과, 상기 홀더핸들(2)에 삽입되어 이탈되지 않도록 하는 록크(1b)가 상단에 형성되며 외측으로 제품을 상, 하로 이동시키고 나사축(1a)과 보올(6)이 삽입되어 구름마찰이 일어나는 요홈(1c)을 갖는 풋트핸들(1)과, 상기 풋트핸들(1)의 하측에 연결되며 상측으로 보올(6)이 삽입되는 훅크(4a)를 갖고 하측으로 쿠션(5)이 삽입되어 미끄러짐이 방지되는 풋트(4)를 구성시킨 것이다.A product bottom plate 3 having a holder insertion hole 3a and a screw hole 3b formed therein, and an insertion hole 2b inserted into the holder insertion hole 3a and fixed to the product bottom plate 3 as a screw 7; A holder handle 2 having a screw 2a of the inner circumferential surface and a lock 1b inserted into the holder handle 2 so as not to be separated are formed at the upper end and the product is moved up and down to the outside and the screw shaft 1a is formed. ) And the foot handle (1) having a groove (1c) is inserted into the frictional friction (6) is inserted, and the hook (4a) is connected to the lower side of the foot handle (1) and the bowl (6) is inserted upward With the cushion (5) is inserted into the lower side to constitute a foot (4) to prevent slipping.

이와같은 구성으로 이루어진 본 고안은 제품밑판(3)에 스크류(7)로 고정되는 홀더핸들(2)의 나사(2a)를 나사축(1a)과 나사식 결합시켜 록크(1b)에 의해 이탈이 방지되도록 한후 요홈(1c)(4b)에 보올(6)이 위치하도록 하여 훅크(4a)를 홀더핸들(2)하측 중앙에 삽입시킨 풋트(4)하측에 쿠션(5)을 삽입시켜 완성된 본 고안의 제품 높낮이 조절시 풋트핸들(1)을 잡고 회전시키게 되면 보올(6)의 구름마찰에 의해 풋트핸들(1)이 회전되면서 나사축(1a)과 나사(2a)의 결합에 의한 나사작용으로 나사축(1a)이 상, 하로 이동되며 돌출 및 삽입됨에 따라 제품의 높낮이가 조절되며 풋트핸들(1)의 회전시 풋트(4)하측의 쿠션(5)이 지면과 밀착력을 향상시켜 풋트(4)의 회전을 방지하므로 제품의 이동이 없이 높낮이만 조절되게 한다.According to the present invention having the above configuration, the screw 2a of the holder handle 2 fixed to the product bottom plate 3 with the screw 7 is screwed with the screw shaft 1a to be separated by the lock 1b. After the prevention, the bowl 6 is placed in the grooves 1c and 4b, and the cushion 5 is inserted into the lower part of the foot 4 where the hook 4a is inserted in the lower center of the holder handle 2. If the foot handle (1) is rotated by holding the foot handle (1) when adjusting the height of the product, the foot handle (1) is rotated by the rolling friction of the bowl (6), which is caused by the screw action of the screw shaft (1a) and the screw (2a). As the screw shaft 1a moves up and down and protrudes and is inserted, the height of the product is adjusted, and when the foot handle 1 rotates, the cushion 5 below the foot 4 improves adhesion to the ground and the foot 4 It prevents the rotation of) so only height is adjusted without product movement.

따라서 풋트핸들(1)의 회전으로 제품의 이동이 없이 화면을 스크린에 정확히 일치시킬수 있게 된다.Therefore, by rotating the foot handle (1) it is possible to exactly match the screen to the screen without moving the product.

이상에서와 같은 본 고안은 프로젝터 제품의 화면을 스크린에 일치시킬 경우 풋트핸들을 회전시키면 풋트상의 보올의 구름마찰에 의해 풋트핸들이 회전되면서 나사작용으로 제품의 유동이 없이 높낮이만 조절할 수 있으며 풋트의 쿠션으로 바닥면과 밀착되어 제품의 밀림이나 유동을 방지하여 스크린에 화면을 신속하며 간편하고 정확하게 일치시킬수 있는 효과가 제공된다.When the foot handle is rotated when the screen of the projector product is matched to the screen, the present invention as described above allows the foot handle to be rotated by the rolling friction of the bowl on the foot, and only the height can be adjusted without the flow of the product by the screw action. Cushioned to the bottom surface to prevent the product from being pushed or flowing, so that the screen can be quickly and easily matched to the screen.
