이 발명은 TV수상기나 모니터등의 화면방향을 시청자가 임의의 원하는 각도로 위치시켜 효과적으로 시청할 수 있도록 한 틸트(Tilt)장치에 관한 것이다.The present invention relates to a tilt device that enables a viewer to effectively watch by positioning a screen direction of a TV receiver or a monitor at any desired angle.

일반적으로, TV수상기나 모니터등은 그 화면 자체의 높낮이를 조절할 수 없도록 제작되므로 받침다이등을 이용하여 시청자가 시청이 용이하도록 높이를 맞추어 화면을 높이거나 혹은 낮추어 사용하게 된다.In general, since the TV receiver or the monitor is not manufactured to adjust the height of the screen itself, it is used to increase or decrease the screen by adjusting the height so that viewers can easily watch using a support die or the like.

그런데, 시청자가 앉거나 누워서 시청하는 경우에 그 시선방향과 TV화면방향이 서로 다르게 됨에 따라 그 만큼 볼 수 있는 화면의 면적이 작아져 시청하는데 불편한 문제가 있다.However, when the viewer is sitting or lying down to watch, the gaze direction and the TV screen direction are different from each other, so that the area of the viewable screen becomes smaller, which is inconvenient to view.

따라서, 최근에는 TV수상기등을 올려놓는 받침다이내에 각종 구동장치들을 설치하여 받침다이의 상단이 경사지거나 또는 회동되도록 함으로써, 시청자가 화면을 원하는 위치로 조정하여 효과적으로 화면을 시청할 수 있도록 하고 있는데, 종래의 이와 같은 장치로서는, 예를들어 일본국 공개 실용신안공보 소화 61-113477호 공보에 개시된 바와 같이 모터로 구동되는 복수의 나사축에 좌, 우 이동이 가능한 슬라이더를 설치하고, 이 슬라이더의 상단부에 축을 중심으로 회동하는 지지판을 설치함으로써 TV수상기등을 상, 하로 틸트시킬 수 있도록 하고 있다.Therefore, in recent years, by installing various driving devices in the support die on which the TV receiver is placed, the upper end of the support die is inclined or rotated, so that the viewer can effectively adjust the screen to a desired position and watch the screen effectively. As such a device of the present invention, as disclosed in, for example, Japanese Unexamined Utility Model Publication No. 61-113477, a slider capable of moving left and right is provided on a plurality of screw shafts driven by a motor, and the upper end of the slider is provided. By installing a support plate that rotates about an axis, the TV receiver can be tilted up and down.

그러나, 이와 같은 장치는 그 구조가 복잡하게 됨은 물론 부품수의 증가로 원가를 상승시키게 된다는 문제가 있다.However, such a device has a problem that the structure is complicated and costs are increased due to the increase in the number of parts.

또한, 제1도 내지 제3도에 나타낸 바와 같은 틸트장치(100)는, 고정부재(10)에 설치된 모터(1)의 기어(2)의 이맞물림되는 감속기어(3)가 래크(4)와 연결되어 상기 모터(1)의 구동에 따라 받침부재(5)가 축(6)을 중심으로 회동되도록 하고 있는데, 상기 받침부재(5)는 중앙의 지지대(7)를 중심으로 하여 양측 방향에 각각 설치된 상, 하측 가이드(8), (8a)에 스프링(9)이 끼워 장착되어 받침부재(5)의 작동시에 회동이 원할히 이루어지도록 하고 있다.In addition, in the tilting device 100 as shown in FIGS. 1 to 3, the reduction gear 3 into which the gear 2 of the motor 2 of the motor 1 installed in the fixing member 10 is engaged is rack 4. Connected to the support member 5 so that the support member 5 is rotated about the shaft 6 according to the driving of the motor 1, and the support member 5 is formed at both sides of the support 7 in the center. The springs 9 are fitted into the upper and lower guides 8 and 8a provided respectively, so that the rotation is smoothly performed when the support member 5 is operated.

그러나, 상기 모터(1)의 구동시에 상기 스프링(9)들의 일정상수(K)에 의하여 모터(1)의 회전방향과 반대로 반발력(F)이 작용하게 된다.However, when the motor 1 is driven, the repulsive force F acts on the contrary to the rotational direction of the motor 1 by the constant constant K of the springs 9.

즉, 상기 받침부재(5)가 축(6)을 중심으로 회동되는 동안에 일측의 스프링(9)에는 소정의 인장력이 작용하게 되므로 모터(1)에는 제2도에서와 같이 화살표 방향으로 반발력(F)이 작용하게 되며, 상기 받침부재(5)가 반대방향으로 회동되는 경우에는 반발력(F)의 방향이 반대로 작용하게 된다.That is, since the predetermined tension is applied to the spring 9 on one side while the support member 5 is rotated about the shaft 6, the repulsive force F in the direction of the arrow as shown in FIG. ) Acts, and when the support member 5 is rotated in the opposite direction, the direction of the repulsive force (F) is reversed.

따라서, 이 반발력(F)이 클 경우에는 모터(1)의 구동력에 악영향을 초래한다는 문제가 있었다.Therefore, when this repulsive force F is large, there exists a problem that it will cause a bad influence on the driving force of the motor 1.

이 발명은 상기한 바와 같은 종래의 문제점들을 감안하여 이루어진 것으로서, 이 발명의 목적은, TV수상기나 모니터등의 틸트장치에 있어서 받침부재의 회동시 구동모터의 회동방향과 반대로 발생하는 반발력을 최소로 일정하게 유지되도록 함과 동시에 받침부재에 진동이 발생되지 않도록 함으로써, 용량이 작은 모터로도 원할하게 구동시킬 수 있는 TV수상기의 틸트장치를 제공함에 있다.The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to minimize the repulsive force generated in the opposite direction of rotation of the drive motor when the support member is rotated in a tilting device such as a TV receiver or a monitor. The present invention provides a tilting apparatus for a TV receiver which can be driven smoothly even by a motor having a small capacity by maintaining a constant and preventing vibration from occurring in the support member.

상기한 바와 같은 목적들을 달성하기 위한 이 발명의 특징은, 모터에 의해 구동되는 받침부재의 하부 양측에 스프링을 각각 설치하여 상기 받침부재가 축을 중심으로 소정각도로 회동되도록한 틸트장치에 있어서, 상기 받침부재의 하부 양측에 각각 설치된 연결봉의 끝단에 형성되는 밸브와, 작동유가 저장되는 용기부의 양측상에 상기 밸브가 끼워져 이동가능하도록 작동되는 피스톤부로 이루어지는 유입장치를 설치하고, 이 유입장치에 의해 상기 받침부재가 소정각도로 회동되도록 한 것에 있다.A feature of the present invention for achieving the above object is, in the tilt device for installing the spring on each side of the lower side of the support member driven by the motor to rotate the support member at a predetermined angle about the axis, the A valve formed at the ends of the connecting rods respectively provided on both lower sides of the supporting member, and an inlet device including a piston part operable to move by inserting the valve on both sides of the container part in which the hydraulic oil is stored; The support member is rotated at a predetermined angle.

이하, 이 발명에 따른 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, the embodiment according to the present invention will be described in detail according to the accompanying drawings.

제4도 내지 제6도는 이 발명에 따른 TV수상기의 틸트장치를 설명하기 위한 도면으로서, 제4도에서와 같이 TV수상기의 하단부에 설치되는 틸트장치(100) 내부의 고정부재(20)의 일측에 리모콘(도시생략) 등에 의해 원격조절이 가능한 모터(11)가 장착되어 있고, 이 모터(11)의 축에 장착된 기어(12)와 감속기어(13)를 개재하여 래크(14)가 이맞물림되도록 설치된다.4 to 6 are views for explaining the tilt device of the TV receiver according to the present invention, one side of the fixing member 20 inside the tilt device 100 installed in the lower end of the TV receiver as shown in FIG. The motor 11 which can be controlled remotely by a remote control (not shown) etc. is attached, and the rack 14 is connected via the gear 12 and the reduction gear 13 attached to the shaft of this motor 11 to this. It is installed to engage.

또한, 상기 래크(14)는 TV수상기나 모니터(도시생략) 등이 올려지는 받침부재(15)의 일측에 고정설치되고, 이 받침부재(15)의 중앙부에 형성된 브라켓에는 축(16)이 설치되어 상기 고정부재(20)상에 장착되는 지지대(17)상단과 연결 설치되어 있다.In addition, the rack 14 is fixed to one side of the support member 15 on which the TV receiver or monitor (not shown) is mounted, and the shaft 16 is installed on the bracket formed at the center of the support member 15. It is connected to the upper end of the support 17 is mounted on the fixing member (20).

한편, 상기 받침부재(15)의 중심에 대하여 소정 거리를 두고 대향되게 돌출편(15a)이 형성되어 있으며, 이 돌출편(15a)들에는 각각 연결봉(18)이 힌지(19)에 의해 회동되도록 설치된다.On the other hand, protruding pieces 15a are formed to face each other at a predetermined distance with respect to the center of the supporting member 15, and the connecting rods 18 are rotated by the hinges 19 on the protruding pieces 15a, respectively. Is installed.

또한, 상기 연결봉(18)의 끝단에는 밸브(18a)가 형성되어 있고, 이 밸브(18a)가 유압장치(200)의 용기부(21) 양측 끝단부에 형성된 피스톤부(22)에 끼워져 장착되며, 상기 용기부(21)내에는 작동유가 저장되어 오리피스(23)를 통하여 유동되도록 설치된다.In addition, a valve 18a is formed at the end of the connecting rod 18, and the valve 18a is fitted to the piston 22 formed at both ends of the container portion 21 of the hydraulic apparatus 200. In addition, the working oil is stored in the container portion 21 and is installed to flow through the orifice 23.

상술한 바와 같은 이 발명은, TV수상기나 모니터등의 화면 방향이 시청자의 시선방향과 일치하지 않게된 경우에 시청자가 임의의 원하는 각도로 화면을 위치시키기 위하여 리모콘을 조작하게 되면 이 리모콘 신호를 틸트장치(100)내의 수신부내에 설치된 마이콤(도시생략)에서 인식하여 모터(11)를 정. 역방향으로 회전시키게 되며, 제4도에서와 같이 모터(11)의 회전력이 축에 장착된 기어(12)의 이맞물림된 감속기어(13)를 통하여 래크(14)로 전달됨에 따라 상기 래크(14)가 화살표 방향으로 이동하게 된다.As described above, the present invention is to tilt the remote control signal when the viewer operates the remote control to position the screen at any desired angle when the screen direction of the TV receiver or the monitor does not match the viewer's gaze direction. The motor 11 is determined by the recognition by a microcomputer (not shown) installed in the receiving unit of the apparatus 100. As shown in FIG. 4, the rotational force of the motor 11 is transmitted to the rack 14 through the meshed reduction gear 13 of the gear 12 mounted on the shaft. ) Will move in the direction of the arrow.

따라서, TV수상기나 모니터등의 본체가 올려진 받침부재(15)가 제5도에서와 같이 축(16)을 중심으로 회동하게 되는데, 이 회동각도(θ)는 중심에 대하여 대략 -10°내지 +10°의 범위이다.Therefore, the supporting member 15 on which the main body such as a TV receiver or a monitor is mounted is rotated about the axis 16 as shown in FIG. 5, and the rotation angle θ is approximately -10 ° with respect to the center. It is in the range of + 10 °.

이때, 상기 받침부재(15)를 반시계 방향으로 회동시키는 경우에는 받침부재(15) 하단부에 형성된 일측(제4도에서 좌측)의 돌출편(15a)에 힌지(19)로 연결된 연결봉(18)을 눌러주게 되므로 제5도에서와 같이 연결봉(18) 끝단의 밸브(18a)가 피스톤부(22) 내부의 오리피스(23)측으로 하강하게 된다.In this case, when the support member 15 is rotated in the counterclockwise direction, the connecting rod 18 connected by the hinge 19 to the protruding piece 15a of one side (left in FIG. 4) formed at the lower end of the support member 15 is provided. Since presses are pressed, the valve 18a at the end of the connecting rod 18 is lowered to the orifice 23 inside the piston 22 as shown in FIG.

따라서, 용기부(21)내의 작동유가 소정의 압축력을 받게되고, 타측(제4도에서 우측)에 설치된 밸브(18a)는 작동유가 밀어내는 힘을 받는 동시에 모터(11)에는 회전력과 반대방향으로 미세한 반발력(F')이 작용하게 된다.Therefore, the hydraulic oil in the container portion 21 receives a predetermined compressive force, and the valve 18a provided on the other side (right side in FIG. 4) receives the force pushed out by the hydraulic oil and the motor 11 in the opposite direction to the rotational force. Fine repulsive force (F ') is to act.

이때, 상기 작동유의 압력이 대기압보다 크므로 상기 받침부재(15)가 소정각도로 계속 회동되는 경우에 받침부재(15)에는 진동이 전혀 발생되지 않게 됨은 물론 상기 모터(11)에 작용하던 반발력(F')이 제6도에 나타낸 바와 같이 최소의 일정한 값을 유지하게 되므로 용량이 작은 모터(11)로도 원할하게 받침부재(15)를 경사시킬 수 있게 된다.At this time, since the pressure of the hydraulic oil is greater than atmospheric pressure, when the support member 15 is continuously rotated at a predetermined angle, the support member 15 is not vibrated at all, as well as the repulsive force acting on the motor 11 ( Since F ') maintains a minimum constant value as shown in FIG. 6, the support member 15 can be smoothly inclined even by the motor 11 having a small capacity.

또한, 받침부재(15)를 시계방향으로 회동시키는 경우에는 상술한 바와 반대로 작동하게 되며, 받침부재(15)의 회동각도(θ)는 리모콘에 의한 모터(11)를 콘트롤하거나 또는 리미트스위치(도시생략) 등을 사용하면 용이하게 조절할 수 있게 된다.In addition, when the support member 15 is rotated in the clockwise direction, the operation is reversed as described above, and the rotation angle θ of the support member 15 controls the motor 11 by a remote controller or a limit switch (not shown). Omit), etc., to facilitate adjustment.

이상에서와 같이 이 발명은, TV수상기나 모니터등의 화면방향을 원격조작에 의해 자유롭게 상, 하 틸트시킬 수 있도록 하여 시청을 보다 효과적으로 할 수 있는 동시에 모터에 작용하는 반발력을 최소로 일정하게 유지되도록 하고, 받침부재에 진동이 발생하지 않도록 함으로써, 용량이 작은 모터로도 원활하게 구동시킬 수 있는 것이다.As described above, the present invention allows the screen direction of a TV set or a monitor to be tilted freely up and down by remote operation, so that the viewing can be more effectively performed and the repulsive force acting on the motor is kept to a minimum. In addition, the vibration is not generated in the support member, so that even a motor having a small capacity can be driven smoothly.
