Second, the present invention performs the function of the left and right rotation and the forward and backward movement using a single motor while the above invention is to control the angle by driving three motors respectively.

Third, the present invention is accompanied by a forward and backward movement when adjusting the angle, but the invention does not perform the function of moving forward and backward from the wall during rotation because the angle is adjusted by the forward and backward movement.

Fourth, the present invention is a method of embedding inside the upper and lower plates of the stand, but the invention is a structure to be mounted between the display device and the fixed plate.

Thus, it can be clearly seen that the structure and function of the invention described above and technically different.

As described above, it can be concluded that there is no similar invention in which the manual type and the electric type are compatible with the stand type angle adjusting device, and the top plate type type and the rotary type are easy.

Accordingly, an object of the present invention is to provide an apparatus for moving forward and backward when the display set is rotated to the left and right to adjust the angle, and to perform the forward movement only when the left and right angles are adjusted.

In another aspect, an object of the present invention is to provide a manual drive device having a manual rotation function by mounting an electric drive and a rotary ring electrically driven using an electric motor.

In addition, an object of the present invention is to provide a table-type angle adjusting device having a structure that the top plate constituting the appearance of the stand may be fixed and the top plate may be rotated in conjunction with the angle adjustment.

In order to achieve the above object, the table-type forward rotation type angle adjustment device for a display according to the present invention is

An upper plate 41 forming an appearance of the stand;

A lower plate 42 forming the base of the stand;

Mounting members 15, 45 and 46 capable of supporting the display set 51 to be fixed or rotated;

Support means for supporting the upper plate 41 in the form of a roller 12 and the forward and backward drive means consisting of a drive body coupled to the two guide rails (13) rotatably mounted on the lower plate (42);

Electric rotary drive means formed in the form of a motor (23) and gears (21, 22) mounted at the end of the forward and backward drive means from the center of rotation, or a manual rotary drive means composed of a rotary ring (27) and a ring guide (28);

It consists of a displacement adjusting means including a forward rotation guide 17 to adjust the rotation function and the forward and backward functions to perform the forward function only when the left and right rotations, and to perform the reverse function when returning to the center position.

In addition, in the angle adjusting device of the table-type forward rotation type for display according to the present invention, the forward and backward drive means is a linear movement in the line of the guide shaft 14 assembled through the rotary support 11 and the gear support 18 It consists of a guide rail 13, which has two guide rails 13 so that the display set 51 can move back and forth stably.

In addition, two guide rails 13 are fixed to one rail fixing plate 15 so as to be interlocked.

The top plate support means is installed by the top plate support roller 12 on the top of the rotary support 11 and the gear support 18 to easily minimize the friction when the top plate 41 interlocked with the guide rail 13 is moved forward and backward It is made to slide.

In addition, the rotation drive means is configured to be operated by electric and manual,

As the electric rotary drive means is rotated in the clockwise or counterclockwise direction of the motor, the display set 51 can be angularly adjusted from side to side, and a rotary gear mounted on the gear support 18 is interlocked for such a function. 21 and a drive gear 22 mounted to the motor 23.

Manual rotation drive means is composed of a ring ring 28 for guiding the drive of the rotary ring 27 and the rotary ring 27 mounted on the gear support 18.

In particular, since the guide rail 13 is composed of two, it is possible not only to move stably when moving forward and backward, but also to secure durability when rotating the display set 51 made of a large weight.

With the above advantages, the large display set 51 may be adopted as an angle adjusting stand at the time of wide spread.

In general, when the electric function is added, the unit price is increased, so it is adopted only to high-end products, and the quantity is limited.

Since the forward and backward movement is made at the same time, the radius of rotation of the set becomes larger, so that the visual effect can be maximized when used for commercial use.

In terms of design, if the exterior height of the stand is too large, the features of the function may have the side effect of the design being lost, so it is generally impossible to use a large high torque motor, but a large motor is required to rotate a large display set, but Even the torque motor can be driven to increase the length of the arm as much as possible to enable the rotational drive of the display set of a large weight, so that it is easy to drive according to the principle of the lever. This is what makes it possible.

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

Consists of a control unit 30 to adjust the function according to the audio-visual, and a stand unit 40 for mounting the display set to form the appearance

On the contrary, in Fig. 1, the combined perspective view of the forward rotating electric stand according to the present invention is shown in detail in full exploded perspective view in Fig. 2.

First, the forward and backward driving unit 10 is assembled with the lower support 42 and the guide shaft 14, the rotary support 11, the rotary gear 21 or the rotary ring 27 and the guide shaft 14 is assembled Gear support 18, a guide rail 13 for linear movement forward and backward along the rod of the guide shaft 14, a rail fixing plate 15 for fixing the two guide rails 13, and a rotation support 11 ) And a top plate support roller 12 mounted on the top of the gear support 18, a forward rotation guide 17 and a forward and backward pin bearing 16 to control forward and backward functions during rotation. .

Next, the rotary unit 20 is electric and manual and can be appropriately selected according to the intended use and purpose.

In other words, if it is necessary to control remotely with auto or remote control, it can be used as electric power. If only simple angle adjustment is needed like general entry type, manual can be selected and used.

When the electric type is selected in the rotary device 20, the rotational force of the rotary gear 21 mounted on the gear support 18, the drive gear 22 mounted on the motor 23, and the drive gear 22 The upper gear washer 24 and the lower gear washer which are assembled to the upper and lower parts of the motor 23 and the drive gear 22 which can be transmitted to the rotary gear 21 to prevent the up and down flow of the rotary gear 21. (25) and a gear fixing nut 26 for fixing the gear and washer.

In the case of the manual type, it is composed of a rotary ring 27 mounted on the gear support 18, and a ring guide 28 to prevent the up and down flow of the rotary ring 27. FIG. Shown in detail in perspective view.

Next, the controller 30 fixes the main board 31 and the main board 31 to the rotation support 11 to control the clockwise or counterclockwise direction of the motor 23 and the rotation angle according to the audiovisual angle. It consists of a board fixing plate 32, and a power cord 33 for applying power.

Although not shown, it may be possible to add the function to the motherboard 31 if the remote control needs to be adjusted.

Finally, the stand part 40 forms an external appearance, and the forward and backward driving part 10 and the rotating device part 20 are mounted, and the display set 51 is fixed.

Therefore, the stand portion 40 is coupled to the upper plate 41 forming the exterior, the lower plate 42 forming the base of the device, the lower plate 42, the rotary shaft bearing 43, which can rotate the rotary support 11, the lower plate Attached to the lower part of the 42, and assembled to the support 45, the support 45, which is mounted on the support 44, the upper plate 41 or the rail fixing plate 15 to serve as a leg of the device and display set 51 It is composed of a rotating shaft washer and a bolt 47 for assembling and coupling the fixed plate 46 for fixing the) and the rotary support 11 to the rotary shaft bearing 43.

8 is shown only in the form of a manual stand, but it can be easily inferred that it can be used in an electric stand as well.

Such a design is easily conceivable, but in practical applications it is difficult in a structure in which the internal materials are exposed to the outside.

The device of the present invention is characterized in that the material inside is not exposed to the outside of the support guide groove 48 even in the left and right rotation or forward and backward movement.

The reason is that the guide rails 13 are covered by the rail fixing plate 15 and the guide shaft 14 is being rotated about the rotary shaft bearing 43.

Therefore, in order to meet the use purpose and purpose of the display and the requirements of the customer, there are various options such as electric and manual, and rotating and fixing the top plate 41.

The main components and members according to the present invention have been described in detail above.

Next, the operation of the angle adjusting device of the table-type forward rotation type for display according to the present invention will be described in detail.

3a, 3b are related plan and perspective views of the forward and backward motion according to the invention,

4A, 4B are shown in related top views and cross-sectional views for left and right rotational motions,

FIG. 5 is a plan view of the forward rotation operation, in which the forward and backward pin bearings 16 are moved along the forward rotation guide 17.

7A and 7B are a plan view and a sectional view of a forward rotation operation of the manual stand,

9A and 9B illustrate two types of operating states for the forward-rotating stand according to the present invention, and FIG. 10 shows the operating states for the conventional left and right rotary types.

3A is a plan view of the operation in which the rail fixing plate 15 at the "A" position moves back and forth by the "a" distance to the "B" position.

Since the two guide rails 13 are fixed to one rail fixing plate 15 and the rail fixing plate 15 is fixed to the upper plate 41 or the support 45, the display set 51 is moved forward and backward from the wall surface. It will move.

At this time, the guide rail 13 is moved forward and backward on the line of the guide shaft 14, as shown in Figure 3b.

3c shows the top plate support roller 12 mounted on the top of the rotation support 11 and the gear support 18.

The upper plate supporting roller 12 serves to slide when the rail fixing plate 15 moves from the "A" position to the "B" position while supporting the lower portion of the upper plate 41.

Therefore, in the end, the display set 51 placed on the upper plate 41 is stably supported in four places such as two places of the guide rails 13 and two places of the upper plate support rollers 12.

4A is a plan view of the operation in which the forward and backward drive unit 10 shown by the solid line is rotated to the "B" position shown by the hatched portion in the "A" position, and the drive gear 22 is rotated to the rotation of the motor 23. Accordingly, the rotary gear 21 is rotated to the left and right, and the driving unit 10 coupled with the rotary gear 21 is shown to be interlocked.

4B is a cross-sectional view of the rotating shaft bearing 43 constituting the central axis of rotation when the rotary gear 21 is rotated.

The rotary shaft bearing 43 is mounted on the upper part of the lower plate 42, and is fixed by the rotary support 11, the rotary shaft washer and the bolt 47, and the upper plate supporting roller 12 is the roller pin 19 on the upper side. The assembled state is shown.

As shown in FIG. 4A, the size of the motor 23 increases in proportion to the rotational torque. The driving torque required for the weight of the display set 51 applied to the upper plate 41 is the motor torque T of the drive gear 22. It is also possible to rotate the rotary gear 21 of the drive torque T * c / d.

○ Motor Rotation Torque: T

T ＞ 필요 구동 토르크○ Drive Torque:

T ＞ Required Drive Torque

Therefore, the rotation torque can be mounted to a relatively small motor 23, so that it can be slimmed as thin as possible.

In FIG. 5, an operation state in which the motor rotates forward from the "A" position to the "B" position according to the forward rotation guide 17 is illustrated.

That is, when the display set 51 is rotated by "θ", the rail fixing plate 15 positioned at the "A" position of the center of the present invention is rotated while advancing to the "B" position by (b-a) cosθ.

○ Angle of rotation: θ

○ Forward distance: (b-a) cosθ

○ Motor Rotation Torque: T

T○ Drive Torque:

FIG. 7a shows that the motor 23 and the rotary gear 21 and the driving gear 22 are replaced by the rotary ring 27 and the rotary ring guide 28 instead of the electric device.

In the manual angle adjustment device, the driving state of the rotary ring 27 and the rotary ring guide 28 during the forward rotation operation is illustrated in FIG. 7B as a cross-sectional view thereof.

Rotating ring guide 28 is mounted to the lower plate 42 serves to prevent the up and down flow of the rotary ring (27).

That is, when the forward and backward pin bearings 16 are moved along the grooves of the forward rotation guide 17, the guide rails 13 linearly move forward and backward and the rotary ring 27 rotates around the rotation shaft bearing 43. At this time, the rotary ring guide 28 is to prevent the vertical flow of the rotary ring (27).

9A, 9B and 10 illustrate the correlation of interference with the wall surface 52 and the top plate rotating type and the fixed type type in comparison with the conventional rotating type.

That is, in FIG. 10, when the display set 51 is attached together with the wall "E" position as shown in the operation state diagram of the conventional left and right rotating stands, the wall and the "B" position and the "θ" are rotated by the "A" position. Interference occurs and rotation is impossible.

Therefore, in this case, the distance between the wall surface 52 and the display set 51 should be separated from the "E" position to the "D" position so that the rotation angle "θ" can be rotated without interference.

This phenomenon should be regarded as half the effect, because no matter how thin the display set, the distance to the wall in order to rotate.

However, in the case of adopting a stand equipped with an angle adjusting device of the table-type forward rotation type for display of the present invention, as shown in FIG. 9A or as the top plate fixed operating state shown in FIG. Since it rotates by the rotation angle "θ" while moving forward, the conventional problem is solved.

In more detail, when the display set 51 is angled from the "A" position to the "B" position or "C" position, in the case of the rotary top plate 41, the upper plate 41 with the display set 51 In the case of the upper plate 41, the upper plate 41 is fixed to the lower plate 42 so as not to rotate as shown in FIG. 9B even though the display set 51 is rotated.

The top plate rotary type and the top plate fixed type have the same specifications and specifications of the internal forward and backward driving part 10 and the rotary device part 20, but they can be beautifully designed because the top plate rotary type does not reveal the hole compared to the top plate fixed type. In terms of structure, the top plate can be manufactured simply so that the cost can be reduced.

In the above description of the present invention, a table-type angle adjusting device having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention can be variously modified, changed, and replaced by those skilled in the art. Should be interpreted as falling within the protection scope of the present invention.
