Description
본 발명은 본체에서 발산된 빔을 후면의 반사경을 통하여 스크린에 투사하는 빔프로젝터(Beam Projector)의 스탠드에 관한 것으로, 더욱 상세하게는 스탠드 자체를 일체화 및 규격화하여 설치장소에 구애받지 않고 본체와 반사경의 위치이동 및 각도조절이 용이하며, 분해조립과 사용이 편리하도록 한 빔 프로젝터용 스탠드에 관한 것이다.The present invention relates to a stand of a beam projector (Beam Projector) for projecting the beam emitted from the main body to the screen through the reflector on the rear, more specifically, the stand and the body itself and the reflector regardless of the installation place It relates to a beam projector stand that is easy to move the position and adjust the angle, and easy to disassemble, assemble and use.
종래의 빔 프로젝터에 사용되는 스탠드는 대부분 본체를 지지하는 수평지지부와 반사경을 지지하는 수직지지부가 별도로 분리 형성되어 있어 고유의 사양 이외에는 생산 및 제작이 어렵고, 사이즈의 변경시나 사양이 바뀔때마다 재설계에 따른 고가의 추가비용이 불가피하여 경제성이 떨어지는 단점이 있었다.Most of the stand used in the conventional beam projector is formed separately from the horizontal support for supporting the main body and the vertical support for supporting the reflector, which is difficult to produce and manufacture other than the original specifications, and redesigned whenever the size is changed or the specifications are changed. Due to the high cost of additional cost is inevitable, there was a disadvantage in economic efficiency.
또한, 수평 및 수직지지부가 개별적으로 형성되어 고정되어 있으므로 본체 및 반사경의 위치이동과 설치가 어렵고, 부분적인 파손이 발생하더라도 스탠드 전체를 재 제작해야 하는 불편함이 있으며, 사용중에는 스탠드의 뒤틀림 현상이 발생하여 선명한 화면을 볼 수 없는 문제점이 있었다.In addition, since the horizontal and vertical support parts are separately formed and fixed, it is difficult to move and install the main body and the reflecting mirror, and there is inconvenience of having to rebuild the whole stand even if partial breakage occurs. There was a problem that can not see the clear screen occurs.
본 발명은 이러한 문제점을 해결하기 위한 것으로 그 목적은 스탠드를 조립식으로 일체화 및 규격화하여 설치 및 사용환경에 크게 구애받지 않고 본체와 반사경의 위치이동 및 각도조절이 용이토록 함에 있다.The present invention has been made to solve this problem, and its purpose is to integrate and standardize the stand in a prefabricated manner so that the position and angle of the body and the reflector can be easily adjusted without being largely dependent on the installation and use environment.
본 발명의 또다른 목적은 스탠드를 규격화하여 제품의 호환성을 높여주므로서 고유의 사양 이외에도 사용이 가능토록 함에 있다.Another object of the present invention is to standardize the stand to increase the compatibility of the product to be used in addition to the unique specifications.

상기와 같이 구성된 본 발명의 동작 및 작용에 대하여 설명하면 다음과 같다.Referring to the operation and operation of the present invention configured as described above are as follows.
먼저, 본 발명의 스탠드는 본체(10)를 지지하는 수평지지부(30)와 반사경(20)을 지지하는 수직지지부(50)가 조립식으로 일체화되어 있고 또한 가이드바(31, 53)와 슬라이드바(32, 54)를 통하여 길이방향으로의 신축이 가능토록 구성되어 있기 때문에 제품의 사양에 따라 전체적인 크기조절이 가능하다.First, in the stand of the present invention, the horizontal support 30 for supporting the main body 10 and the vertical support 50 for supporting the reflector 20 are assembled integrally, and the guide bars 31 and 53 and the slide bar ( 32, 54) can be stretched in the longitudinal direction, so the overall size can be adjusted according to the specifications of the product.
따라서, 사용자는 본체와 반사경의 크기를 감안하여 수평지지부와 수직지지부의 크기를 조절한 다음 스크류(35, 65)를 체결하여 고정시키고, 다리(34)의 높이를 조절하여 전체적인 수평 및 수직상태를 유지시킨다.Therefore, the user adjusts the size of the horizontal support and the vertical support in consideration of the size of the main body and the reflector, and then fasten by fixing the screws (35, 65), and adjust the height of the legs 34 to adjust the overall horizontal and vertical state Keep it.
이후, 본체(90)의 각도를 조절할 경우에는 먼저 각도조절부(40)의 손잡이(47)를 회전시켜 각도조절판(44)을 승하강시키므로서 각도를 대략적으로 조절한 다음 본체의 지지편을 각도조절홈(44a)의 적정위치에 고정시켜 미세하게 완전히 조절한다.Subsequently, when adjusting the angle of the main body 90, first adjust the angle by roughly raising and lowering the angle adjusting plate 44 by rotating the handle 47 of the angle adjusting portion 40, and then angle the support piece of the main body It is fixed at the proper position of the adjusting groove 44a and finely adjusted completely.
또한, 반사경(20)의 각도를 조절할 경우에는 먼저 각도조절부(60)에 설치된 반사경을 회전시켜 가장 최적의 위치에 고정시킨 다음 이 위치에서 지지편과 각도조절판(63)의 각도조절홈(63b)을 체결하면 된다.In addition, when adjusting the angle of the reflector 20, first rotate the reflector installed in the angle adjusting unit 60 to fix it in the most optimal position, then at this position the angle adjusting groove 63b of the support piece and the angle adjusting plate 63. ).
상기와 같은 동작은 사용중에도 가능하며, 빔 프로젝터의 크기나 사양이 변하더라도 얼마든지 조절할 수 있다.The above operation is possible even during use, and can be adjusted as much as the size or specification of the beam projector changes.
이상에서 설명한 바와 같이 본 발명은 빔 프로젝터의 스탠드를 조립식, 일체형, 규격화하여 설치장소와 사용환경에 구애받지 않고 본체와 반사경을 위치이동 및 각도조절이 자유로우며, 분해조립과 사용이 편리하고, 제품의 크기 및 사양에 관계없이 폭넓게 사용할 수 있는 것이다.As described above, in the present invention, the stand of the beam projector is assembled, integrated, and standardized so that the body and the reflector can be freely moved and angle-adjusted regardless of the installation location and environment, and the assembly and use of the product is convenient. It can be used widely regardless of size and specification.
또한, 본 발명은 스탠드 자체를 규격화하여 제품의 호환성을 높여주므로서 생산성 향상과 원가절감에도 기여할 수 있는 것이다.In addition, the present invention can contribute to productivity and cost reduction by increasing the compatibility of the product by standardizing the stand itself.
