Description

TURNTABLE FOR FLAT PANNEL DISPLAY OF STANDING TYPE}

The present invention relates to a rotatable turntable capable of easily adjusting the viewing angle of a display display device such as a TV or a monitor manufactured using a flat panel display panel such as a PDP and an LCD to a desired angle. In the left and right direction, the viewer can finely adjust the desired angle, and the remote control can be easily controlled by the remote control, and when the left and right rotation, the display product moves to the front, which greatly improves the insufficient rotation angle due to interference with the wall. It relates to a turntable for display.

The present invention is characterized in that it comprises a rotary plate which is converted into two degrees of freedom motion such as a linear motion by one degree of freedom of the feed screw is rotated left and right by a rotary link and a linear motion is moved forward and backward. It is done.

The rotating plate of the present invention can be smoothly operated by the rotation of the ball during the linear motion and the rotational movement for a large-scale heavy-duty flat panel display product by being supported by the ball of a plurality of ball pedestals and functions to stably support the ball when stopped. If it is broken is characterized in that it comprises a plurality of ball pedestal easy to replace it.

The present invention also relates to a rotating fixing plate configured by dividing the outer or part of the rotating plate of the present invention to separately install the rotating fixing plate, which can be replaced with the stand according to the shape and size of the stand of various flat panel display products. It features.

Conventionally, TV monitors using cathode ray tubes had a turntable that rotates manually, but TV or commercial monitors made using flat panel displays such as plasma display panels (PDPs) and liquid crystal displays (LCDs) have screen sizes. It is true that the development of turntables with the ability to adjust the viewer's desired angle has been impossible due to the increase in size, which is why the research and development of TV makers have mainly focused on improving the quality of the viewing angle of flat panel TVs.

Despite the fact that the viewing angle of the TV company was developed close to 180 °, when watching TV from the side rather than from the front, the sensitivity to the liveliness coming from the scene on the screen is lowered.

In addition, in the case of sports such as dramas or football, which are reorganized in a series by various broadcasting means along with various TV channels, programs are broadcast for a long time, so the viewers' TV watching time is also increasing.

Naturally, because of the above reason, the viewer's attitude and position of TV viewing tend to be changed, so it is often necessary to adjust the viewing angle of the TV accordingly.

As flat-panel TVs are spreading in TV monitors using cathode ray tubes, the size of the TV becomes larger and the weight becomes heavier. Therefore, when the flat-panel TV is rotated on the turntable, it is inconvenient to operate by hand and the flat-panel TV becomes slim. Inadvertent accidents can lead to safety accidents, which will be very unstable to operate manually.

This is especially true for women and senior citizens.

Therefore, the electric motor-type auto-rotation function that rotates with the remote control remotely rather than manually holding and rotating the display product can eliminate the safety problem and increase the convenience of use.

Since the shape of the flat-panel TV is wider than the height, it is only rotated in a limited angle range due to interference by the wall when rotating to the left and right, so that it can be improved to a wider rotation angle if it can be moved from the wall to the front. In order to rotate a turntable for a TV monitor using a conventional cathode ray tube, several balls were inserted, but in this case, the ball was not easily replaced when the ball was broken.

In the present invention, by inserting two or more balls into the top of the pedestal of the turntable to be integrated with the pedestal to replace the pedestal so that the ball is also replaced by a structure that can be replaced easily in case of damage, the ball pedestal is a flat plate Basically, in rotating the TV, it has a function of smooth rotation as well as a stable support at the time of stopping, and it is easy to replace in case of possible damage.

In addition, since the TV makers' flat TV stands are produced by various companies and models, it is impossible to turntables that satisfy all the stands.

Therefore, the safest assembly structure will be formed if the stand can be fixed to the turntable of the turntable.

However, if the stand is much larger than the rotating plate, it is structurally impossible to fix the stand to the rotating plate, so the rotating plate must be made large in accordance with the stand.

The larger the turntable, the smaller the angle of rotation of the flat panel display, so design it with considerations when sizing the turntable.

When the stand must be installed on the rotating plate without the flat panel TV fixed, the non-slip member is preferably attached to the upper part of the rotating plate in order to stably place the flat panel TV when the rotating plate rotates. It would be desirable to attach it partially rather than as a whole because it does not match the appearance of it.

Because of the above-described reasons, the structure, size, and shape of the stand are different for each TV company, model, and stand, and the price is cheaper if only the rotating fixing plate composed of the outside or part of the rotating plate can be replaced without replacing the whole rotating plate. Installation and replacement will be easy.

However, when the stand cannot be fixed and the flat panel TV cannot be placed on the top of the rotating plate, it may be more effective to separately install the rotating fixing plate composed of the outside or a part of the rotating plate to which the anti-slip member is attached.

Even in the case of a rotating fixing plate to which a non-slip member is attached, it should be obvious that a structure including the whole stand placed on the turntable should be manufactured according to the shape and size of the stand model of the TV manufacturer.

The structure and form of flat-panel TVs will be more diverse in design in the future.

Also, the image display method of flat-panel TVs will be changed in various ways.

The appearance of flat-panel TVs capable of stereoscopic screens is not too long. Ultra-slim TVs are also expected to be developed and commercialized.

Accordingly, the turntable for flat panel display will also be changed into various structures, and will be developed as a product that can embrace the functions of the various TVs.

In other words, the development of ultra-slim turntables, turntables with various design forms, and multifunctional turntables with improved convenience will be further activated.

Looking at a more specific conventional display angle adjusting device, the user is flat in a certain angle range in the 'audio-visual adjustment device of the flat image display device' published Patent Publication No. 1997-51720 (published July 29, 1997) After holding the TV and adjusting the desired angle, the adjustment member is moved forward to fix the position so that the elderly or women can not easily adjust the angle of heavy flat-panel TVs. There was also a risk of inconvenience and safety accidents.

Furthermore, in the conventional device that simply rotates the flat panel display, the left and right ends of the display are hit by a wall surface that is difficult to rotate due to the limitation of the rotation angle.

The present invention is to rotate the flat panel TV by manipulating a driving means such as an electric motor using a remote control from a technique of manually rotating a turntable for adjusting the viewing angle of a TV monitor using a cathode ray tube of a conventional cathode ray tube. It is an object of the present invention to provide a turntable that satisfies the following four points to solve the technique of adjusting the degree.

First, in order to reduce interference with the wall of the left and right end surfaces of the flat panel TV caused by the left and right rotation of the rotary plate located above the turntable by the remote controller operation, the rotating plate itself on which the flat panel TV is placed is moved forward from the wall. Giving function

Secondly, in order to drive the rotating plate for two degrees of freedom, such as the rotary motion and the linear motion, by fixing the rotary link to the rotary plate according to the linear motion of one degree of freedom of the feed screw, the structure is simplified and the price is reduced. Savings and noise to a minimum.

Third, in order to smoothly rotate and linearly rotate the rotating plate on which the flat-panel TV, which is a large-scale heavy product, is inserted, the lower part of the rotating plate is assembled with the ball and the pedestal in one piece. When the ball is damaged, it is easy to repair by replacing the ball base with a cylinder.

Fourth, since flat panel TV stands vary by flat panel TV company or product type, it is difficult to produce the specifications of the turntable's rotating plate according to the stand, and the unit price of the product increases significantly. It is to achieve easy fixing of the stand by flat panel TV company or product type by installing the rotating fixing plate suitable for the stand by installing separately.

In order to achieve the above object, the turntable according to the present invention includes a feed screw for linear movement by a driving means of an electric motor, and a turntable base on which a ball base for supporting a turntable and smooth rotation is fixed, at an upper portion of the turntable. Rotating plate is assembled by rotating link to make rotational and linear motion, and the rotating angle of flat panel display is controlled. The case that externally transfers screw with rotating motor, rotating link, ball base and electronic control board attached to the electric motor at the bottom of turntable It is made, including.

In addition, the turntable according to the present invention includes an electronic control board for controlling a driving means such as an electric motor operated by a remote control, and the function and the ball to move forward from the wall forward when the rotary plate of the turntable rotates left or right The pedestal is characterized in that the above operation is performed smoothly and stably.

In addition, the turntable according to the present invention comprises a rotatable rotating plate which is composed of the inside or part of the rotating plate on which the stand of the flat panel TV is placed or fixed, and separately install and fix the rotating fixing plate to embrace different stands according to the flat panel TV company or product model. consist of.

At this time, the rotary fixing plate is directly assembled with the stand and the rotary link, and the rotary link transmitted from the linear motion of the transfer screw transmits the rotation and linear motion to the rotary plate, the stand, and the flat panel TV as it is. In the case where the fixing to the circuit fixing plate is impossible, the non-slip member is also to be attached to the upper surface of the rotating fixing plate.

The turntable according to the present invention is an automatic motor driven by an electric motor rather than a manual motor, so that the viewing angle of the flat panel TV can be easily adjusted using a remote remote controller, so that the elderly and the elderly can easily adjust the viewing angle of the flat panel TV and the viewer wants. Compared to the function of finely adjusting the rotation angle in the direction, the components are simpler, which lowers the manufacturing cost, increases productivity, and reduces the risk of failure.

In the past, various functions of left, right, up, down, front and back have been developed in the wall-mounted bracket for installing flat panel TVs on the wall. In this case, the rotation angle range of the flat panel TV can be improved by adding a function of moving forward from the wall for automatic angle adjustment of the turntable like the wall mount holder.

In the case of the stand type, in order to satisfy the above functions, smooth rotation and stable support are important, so the ball pedestal according to the present invention is not only largely effective in obtaining structural convenience and safety, but also configured to facilitate post management.

The rotating fixing plate fixed to the turntable of the turntable according to the present invention is configured to stably adjust the rotation angle of the stand of various flat panel TVs regardless of whether it is determined that there is no difficulty in commercialization or dissemination.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The material is made of the same material as a common cabinet: glass or injection plastic, wood, steel.

The rotating plate assembly 10 is made up of various shapes and sizes to harmonize with the design of the TV.

In addition, as mentioned above, there may be various fixing methods depending on how the stand of the flat panel TV is placed. In general, a turntable for a TV may be used by placing a TV on a turntable.

However, even if a TV company is designed to be packaged and fixed with a TV according to various sales configurations, the function of this turntable will be more safe and secure. The structure thereof is shown in detail in FIGS. 3A and 3B.

The rotary plate assembly 10 is fixed to the rotary plate 11, the rotary plate 11, the rotational fixed plate 12 made of a strong material so as not to be damaged by the rotational force, linear movement of the nut 32 of the transfer screw assembly 30 Consists of a fixed bolt (13A, 13B) that receives the transmission to the rotating plate (11).

For the above configuration and another configuration may be composed of the upper fixing plate 14 and the lower fixing plate 15 for transmitting a rotational force to the rotating plate 10 by fixing a portion of the rotating plate 11 in the upper and lower.

In particular, it is important to harmonize the design according to the flat-panel TV placed on the bar rotating plate 10 that can achieve a variety of shapes and sizes.

In order to prevent the flat panel TV from slipping functionally, an anti-slip member can be attached to the surface of the upper fixing plate 14 for use.

The base assembly 20 illustrated in the case-incorporated component coupling cross-sectional view of FIG. 4 is a core part in which a functional part for rotating operation is incorporated, and a guide groove A1 processed in the turntable base 21 and the turntable base 21. A2 is a rotary link 22 that transmits a linear movement along the transfer screw assembly 30, the full length assembly 40, the ball base 50, and the like, which will be described in detail below. It consists of a fixing nut 23, a base screw 24, and a case 25 and a case screw 26 which protect them from the exterior.

The feed screw assembly 30 includes a motor 33 and a reducer 34 that cause rotational force of the screw, a nut 32 for linear movement by receiving the rotational movement of the screw, and a transfer screw assembly 30 to the turntable base 21. It consists of a fixing bracket 35 and the bracket screw 36 for fixing to.

The nut 32 is coupled to the rotary link 22 so that the linear motion of the nut is transmitted to the rotary link so that the rotary link moves along the nut guide groove A1 of the turntable base 21.

The electronic assembly 40 is an electronic control board for controlling the rotation of the motor 33 by detecting a signal of the remote control 44 when operating with the remote control 44 to adjust the angle of the flat-panel TV at the viewing position of the viewer ( 41), it is composed of an adapter 42, a plug 43 for converting AC power to DC and adjusting the voltage.

The ball pedestal 50 is a part supporting the turntable base 21 at the bottom and supporting all weights including the entire flat panel TV, and the ball 53 is inserted into the rotating plate 11 so as to smoothly rotate. do.

The ball pedestal 50 is a pedestal body 51, pedestal top plate 52, the ball 53, pedestal rubber 54, the base screw as shown in the combined cross-sectional and exploded perspective view of the ball pedestal shown in detail in FIG. 55).

The pedestal top plate 52 is coupled to the ball 53 so as to smoothly rotate so as not to be separated out, and the pedestal rubber 54 serves to seat the weight of the turntable including the flat panel TV.

Ball pedestal 50 is configured to facilitate the assembly and disassembly from the outside while performing two functions, it is configured to be convenient at the time of replacement or repair.

Even if the ball 53 is damaged when the product is used for a long time, it is easily disassembled so that the ball 53 can be replaced or the entire ball base 50 can be easily replaced.

The operation of the turntable for a stand-type flat panel display described above is shown in FIG. 6 in a combined perspective view and a cross-sectional view of a front screen state before operation and a right rotation state after operation, respectively.

First, when the user operates the remote controller 44 to adjust the viewing angle by rotating the flat panel TV, the electronic control board 41 detects a signal of the remote controller 44 and power is supplied to the motor 33 together with the rotation signal. do.

As the motor 33 rotates, the rotational speed is adjusted via the reducer 44 to conform to the function of the present invention.

The decelerating force is transmitted to the feed screw 31 at an appropriate rotation speed, and the feed screw 31 starts to rotate.

The rotational movement of the conveying screw 31 is converted to the linear movement of the nut 32 so that the nut 32 is conveyed on the conveying screw 31.

Since the rotary link 22 is coupled to the nut 32 by the fixing bolt 13A and the fixing nut 23, the linear movement of the nut 32 is transmitted to the rotary link 22 so that the rotary link 22 is turnedtable base ( 21 is conveyed along the nut guide groove A1 processed.

The direction of the nut 32 moving in the nut guide groove A1 is determined according to the left and right rotation directions, which are in accordance with a signal of the remote controller 44 which is operated in accordance with the direction desired by the user.

Accordingly, when the rotary link 22 coupled to the nut 32 starts to move in the center position, the fixing bolt 13B of the other connection part of the rotary link 22 moves along the rotary link guide groove A2. do.

The linear motion along the nut guide groove A1 and the rotary link guide groove A2 of the fixing bolts 13A and 13B is fixed to the rotating plate 11 so that the rotating plate 11 is rotated. Switched to to perform the function of adjusting the angle of the display 71, such as a flat panel TV.

Since a heavy object such as a flat-panel TV is placed on the rotating plate 11, the ball 53 inserted in the ball pedestal 50 has a frictional force because it is preferable that the ball 53 rotates like a bearing principle with low frictional force in order to smoothly rotate. To minimize rotation

Although FIG. 6B illustrates a right turn operation state, the same principle may be used to adjust the angle of the display 71 by turning left, but it may be easily understood.

That is, in order to rotate in the opposite direction by rotating the rotation of the motor 33 in the opposite direction, the nut 32 is transferred to its original position. When the nut 32 returns to the center position of the transfer screw 31, the screen of the display 71 faces the front.

From the moment passing through the center position, the display 71 rotates to the left side opposite to that of FIG. 6B, so that the viewing angle of the display 71 such as a flat panel TV is adjusted to the left.

The operation principle and operation relationship for the turntable for a table-top flat panel display according to the present invention have been described in the operation sequence.

This will be described in more detail with reference to an example related to the turntable of the present invention in actual use.

Figure 1 schematically shows the turntable according to the invention placed on the cabinet combined with the display 71 product.

3 shows a state in which the turntable according to the invention is actually combined with the display 71 product.

In particular, FIG. 3 illustrates a coupling state of the other stands 72A and 72B according to the display 71 product.

The stand 72A of the display 71 product is fixed to the top of the rotating plate 11 by the stand fixing screw 74 and the display 71 is inserted into the stand 72A to the display fixing screw 75. Is fixed.

Therefore, since the display 71 such as a flat panel TV is fixed to the upper part of the rotating plate 11, the display 71 also rotates according to the rotation of the rotating plate 11.

3A, the stand 72B of the display 71 product is not fixed to the rotating plate 11, but is simply placed on the upper portion.

When the stand 72B of the display 71 product is fixed to the display 71 by the display fixing screw 75 and the stand 72B is placed on the upper side of the rotating plate 11, the rotation of the rotating plate 11 is performed. It will rotate.

However, since the shape and size of the display 71 varies, accordingly, when the shape of the rotating plate 11 is changed, there is no productivity and the unit price is rapidly increased. As a result, an upper fixing plate configured as a part of the rotating plate 11 is illustrated in FIG. 6B. If the stand 72B of the display 71 is placed on the upper fixing plate 14 by separately installing the 14A, only the upper fixing plate 14 adapted to the shape and size of the display 71 may be replaced.

That is, if only the upper fixing plate (14A) consisting of the configuration of the rotating plate 11, rather than replacement for the entire rotating plate 11, the productivity is also increased, and the cost savings effect will be easy to install workability.

Since the shape and size of the upper fixing plate 14A will be easily manufactured in various ways, it will be possible to research and develop products of various designs.

As shown in FIG. 6B, the upper fixing plate 14A and the lower fixing plate 15 are fixed to the rotating plate 11 by fixing bolts 13A and 13B, thereby stably smoothly rotating the rotating plate 11.

In this case, since the shape of the stand 72B shown in FIG. 6B is not fixed to the rotating plate 11, when the display 72 becomes unstable due to the rotation operation of the display 71, the surface of the stand 72B is not slipped on the surface as shown in the upper fixing plate 14B of FIG. 7. Attaching the member can more stably replace the product of the display 71 despite the rotational movement.

Also, since the non-slip member is generally difficult to match with other products by design, it is more aesthetically attached to a part of the rotary plate 11 like the upper fixing plate 14B than to attach the non-slip member as a whole. It would be desirable as well.

Figure 7 shows an example applied to the stand for flat panel TV of the turntable for stand-type flat panel display according to the present invention.

1 shows an application example in which the turntable of the present invention is placed on a TV rack such as a cabinet 73, but the turntable of the present invention is fixed by a support 79B on the stand of FIG. It is shown to adjust the rotation angle of the display 71.

When the rotation is operated by the remote controller 44, the stand base 76 is made of heavy material, so that only the rotary plate 11 on the top of the turntable base 21 of the present invention is rotated in a state of being stably fixed to the floor. The rotation angle of the display 71 is adjusted.

At this time, the turntable base 21 and the glass shelf 78 are fixed to the stand pole 77 by the support base 79A, 79B.

In general, audio and video related accessories are placed on the glass shelf 78.

In addition, the stand base 76 is generally used to be movable by attaching wheels than the general floor fixing.

As mentioned above, in the mobile type, in particular, since the product of the display 71 is unstablely placed, it is preferable that the non-slip member is attached to the upper fixing plate 14B.

In the above description of the present invention with reference to the accompanying drawings, but with a focus on a turntable having a specific shape and structure, the present invention can be variously modified, changed and replaced by those skilled in the art, such modifications, changes and substitutions the present invention It should be interpreted as falling within the protection scope of.
