BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly, to a display device that can more efficiently use a space in which a display device is placed, and can support a display body that is large in size simply and conveniently.

A display device is a device that can be exemplified as a monitor or a television, and includes a main body in which a display module is accommodated, a stand supporting the main body, and a base provided at a lower end of the stand. In addition, the display device should allow the user to conveniently change the position of the main body to a desired position. To this end, it is common to have an elastic device embedded therein so as to conveniently move the position while the weight of the display module is supported. to be.

Furthermore, in most display devices, the main components of the elastic device are inserted in the stand. Thus, the thickness of the stand becomes thick, which is inconvenient for the user.

In addition, as the size of the main body increases, the weight of the main body increases, so that the size of the base also increases to support this. However, the larger the base, the more uncomfortable the user. For example, the desk space becomes narrower, which is inconvenient for the user.

The present invention has been made to solve the above problems, and proposes a display device in which the stand is made slimmer by changing the configuration of the elastic device supporting the weight of the main body.

In addition, the present invention proposes a display device that can support a large display main body stably, reduce the area on which the display device is placed, and furthermore, by varying the support area of the display device base. do.

The display device of the present invention, the display main body; An elevating member that elevates with the display main body; A holding portion for guiding the lifting movement of the lifting member; A base supporting the lower side of the support portion; A leg rotatable relative to the base; A slider placed on the leg and moving; A wire connecting the elevating member and the slider; At least one deflection portion for changing an extension direction of the wire; And a spring providing an elastic force to the movement of the slider.

The display device of the present invention, the display main body; A support portion supporting the display body; A base for supporting the support against the bottom surface such that the support is rotatable; And a leg which is rotatable in a direction parallel to the bottom surface while being supported by the base, so that the support area of the display main body is adjustable.

The display device of the present invention, the display main body; An elevating member for elevating up and down together with the display main body; A holding portion for guiding the operation of the elevating member; A base supporting the support against the bottom surface; A leg capable of rotating in a direction parallel to the bottom surface while being supported by the base, such that a support area of the display main body is adjustable; A slider guided and moved by the leg; And a wire connecting the elevating member and the slider.

According to the present invention, a slimmer display device can be obtained, and the area of the bottom surface occupied by the display device can be changed, and in particular, the area can be reduced, thereby increasing the convenience of the user.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention.

1 is a front perspective view of a display device according to the present invention, Figure 2 is a rear perspective view of the holding portion is removed from the display device according to the present invention.

1 and 2, at least a main body 1 in which a display module is accommodated, a stand 2 provided at the rear of the main body 1, and a base 3 placed at a lower end of the stand 2. And legs 4 and 5 extending to both sides of the base 3. Here, since there is no built-in elastic device inside the stand 2, it is possible to obtain the advantage that the stand is more slim, and the legs (4) (5) to the rear with the base (3) as a support point Because it can be folded, the user can increase the utilization of the space.

Hereinafter, a detailed configuration will be described.

The stand 2 has a rear fixing portion 11 fixed to the rear surface of the main body 2, an inclined hinge 12 provided on the rear surface of the rear fixing portion, and an elevating hinge in which the inclined hinge is fixed to an upper end portion. The member 21 and the support part 22 which support the lifting action of the lifting member 21 are provided.

In addition, a pair of first pulleys 23 are fixed to the support portion 22 so as to be rotatable, and wires 6 are wound around the first pulleys 23, and ends of the wires 6 are fixed. Is connected to the elevating member 21. Therefore, when the main body 2 is lowered, the wire is pulled by the operation of the rear fixing portion 11, the inclined hinge 12, and the elevating member 21 are lowered together. In other words, when the elevating member descends while the first pulley 23 is fixed, the wire 6 is pulled downward using the first pulley 23 as a supporting point.

In addition, the support portion 22, in order to smoothly guide the vertical lifting operation of the elevating member 21, to guide the lifting movement in the state accommodated in the elevating member 21 therein.

In addition, the base cover 33 is placed on the upper side of the base 3 to cover the upper surface of the base 3, and the hinge body 7 is formed in the rear space formed by the base 3 and the base cover 33. It is provided to rotatably support the holding portion (22).

In addition, stopper guides 9 are provided on both sides of the hinge body 7 to support the pivoting state of the support 22. Grooves 91 and 92 are formed in the stopper guide 9. The folding stopper 94 selectively caught by the grooves 91 and 92, the guide shaft 73 for guiding the movement of the folding stopper 94, and the folding stopper 94 are pushed outward. A push spring 96 providing a force and a jaw 95 are formed to prevent the folding stopper 94 from escaping out of the fraud stopper guide 9.

At least a portion of the folding stopper 94-the inner portion-is hung on the strut portion 22, and at least a portion of the folding stopper 94-the outer portion-is any of the grooves 91, 92. It is caught in one. In this state, when the user presses the folding stopper 94, the folding stopper 94 is pushed inwards to overcome the elastic force of the push spring 96, and the user can then fold or unfold the support 22. Will be. Of course, in the state in which the support portion 22 is unfolded and folded, the folding stoppers 94 are caught in different grooves, respectively, which is in the state in which the support portion 22 is unfolded. When the display device of the present invention is in a stand state, and the state is caught in the second groove 92, the display device of the present invention is a wall mount state in the state in which the support portion 22 is folded.

In addition, a second pulley 71 is placed inside the stopper guide 9. The second pulley 71 is provided to allow the wire 6 to be bent toward the base 3, so that the wire 6 is smoothly rotated when the wire 6 is moved to allow the wire 6 to move smoothly. In addition, a wire guide 34 is provided at an upper side adjacent to the second pulley 71, so that the wire 6 does not fall out of the second pulley 71 even when the wire 6 is loose due to the loss of tension. do.

On the other hand, a base bracket 33 is placed in front of the space provided by the base 3 and the base cover 31 to regulate the movement of the legs 4 and 5.

The front end of the base 3 also has a third pulley 72 which allows the wire to be bent and extended toward the legs 4 and 5, and the wire 4 when the legs 4 and 5 are folded. A fourth pulley 73 is provided which smoothly bends 6 to prevent damage to the wire 6. Here, the third pulley 72 and the fourth pulley 73 set a positional relationship that can guide the operation of the legs 4 and 5, and the positional relationship of the leg shown in FIG. It demonstrates with reference to a top view.

4, the 2nd leg 5 makes the 4th pulley 73 the center of rotation. Further, since the third pulley 72 is located on the left side of the fourth pulley 73, the force that the wire pulls in turn acts as a force that rotates the second leg 5 clockwise. However, since the second leg 5 is supported by the base bracket 33, it does not rotate clockwise. Thereby, even if the wire 6 is pulled, the second legs 4 and 5 are prevented from rotating clockwise. Since the action of the second leg 5 is the same in the first leg 4, the detailed description thereof is omitted.

In addition, the legs 4 and 5 are parts supported by the fourth pulley 73 as described above, and the user uses the fourth pulley 73 to lift the legs 4 and 5. Can be rotated. Therefore, when the user intends to use the display device in the wall mount mode, the second leg 5 on the right side is rotated counterclockwise around the fourth pulley 73 based on the drawing and the drawing is rotated. As a reference, the second leg 4 on the left side can be rotated clockwise.

The legs 4 and 5 also have a built-in elastic device capable of supporting the weight of the main body 1. Specifically, the slider 53 to which the end of the wire 6 is connected and the guider 52 for guiding the movement of the slider 53 are the same.

The slider 53 is an article that is pulled and moved by the wire 6, and an elastic force is generated by the interaction of the slider 53 and the guider 52. Generation of the elastic force will be described with reference to the cross-sectional view taken along line II ′ of FIG. 1 shown in FIG. 3.

Referring to FIG. 3, a spring 53 having one end fixed to the guider 52 is rolled into a substantially circular shape, and the spring 53 is pushed by the slider 53. However, since the slider 53 is an article pulled by the wire 6, the spring 53 provides an elastic force that hinders the movement of the slider 53.

Here, the spring 53 can be illustrated as a spring, and according to the spring 53 is a constant elastic force is always generated, the user has the advantage that the user can adjust the height of the body more conveniently.

Reference numerals 41 and 51, which are not described, are leg covers, and the leg covers cover the legs, thereby forming the entire structure of the legs.

The display device having the structure as described above is characterized in that the upper and lower heights of the main body 1 can be adjusted while the self weight of the main body is supported by the wire 6. Hereinafter, the operation of adjusting the height of the main body by the display device will be described by exemplifying an operation of lowering the height of the main body by the user.

First, when the user lowers the main body 1, the wire 6 having an end connected to the elevating member 21 is also pulled downward like the main body 1. At this time, since the first pulley 23 is rotated in a state fixed to the support 23, the extending direction of the wire 6 is smoothly bent downward. The wire 6 is gently bent forward by the wire guide 34 and the second pulley 71. Then, the second pulley 72 is gently bent again toward the legs 4 and 5. The end of the wire 6 is connected to the slider 53.

As a result, the extension direction of the wire 6 is bent through the pulley while both ends are connected to the elevating member 21 and the slider 53.

Therefore, when the user pulls the main body 1 downward, the wire pulls the slider 53 and the slider 53 is moved while being guided by the guider 52. Here, the elastic force of the spring 53 is provided while the slider 53 is moving. Therefore, when the user stops pulling the main body 1 downward, the downward movement of the main body 1 can be stopped by the frictional force generated at the contact portion between the respective components and the elastic force of the spring 53. Similarly, when the user moves the main body 1 upward, the main body 1 can be moved upward by a force less than the weight of the main body 1 by the elastic force of the spring 53.

As will be described, the elastic device for supporting the weight of the body is provided on the base side instead of the stand, but there is no problem in supporting the weight of the body. In addition, in the present invention, since the elastic devices are provided in two places, more elastic force can be exerted, whereby there is no problem in supporting the main body of the large screen.

Meanwhile, in the above description, although a pair of parts, for example, a wire, a leg, a dorde, and the like are provided with a pair, only one part is described, which is the same description. This is because they can be used together. Therefore, it is assumed that the description of the other part, which is described, is applied to any one part that does not have a specific description.

5 and 6 are plan views of the display device according to the present invention. FIG. 5 is a state in which a leg is not grounded, and FIG. 6 illustrates a state in which one leg is folded at an angle.

5 and 6, the area occupied by the display device of the present invention is increased by the space occupied by the legs 4 and 5. In order to support a large body, a moving track of the body is considered. But it should be a certain area. However, the user may need to use a space occupied by the display device, such as placing a desk in a space such as a desk while using the display device.

In this case, as shown in FIG. 6, the legs 4 and 5 may be pushed to one side. Referring to the second leg 5 as a reference, when the second leg 5 is pushed, the second leg 5 is rotated around the fourth pulley 73. At this time, since the positions of the fourth pulley 73, which is the center of rotation of the second leg 5, and the third pulley 72, which is the support point of the second wire 62, are different from each other, Wire 62 is required, which means that the second wire 62 is pulled to the second leg 5 side.

In this case, the slider may be pulled inward or the main body 1 may move upward, thereby causing deformation.

If the friction force relationship of the display device is set by moving the main body 1 upward, the second wire 62 has no problem because the longer length is required, but the first wire Reference numeral 61 provides a long wire between the slider and the elevating member without requiring a long wire. Then, the first wire 61 will have a portion that is irregularly bent in places without tension, which will be clearly understood by looking at the first wire 61 shown in FIG. On the other hand, even in such a case, in order to prevent the first wire 61 from being pulled out of the second pulley 71, a wire guide 34 is provided, and the operation of the display apparatus of the present invention is performed by the wire guide 34. The reliability of the image is further improved.

Although it is described that the wire guide 34 is provided only in the second pulley 71, the same will be said for the other pulleys.

When the leg is folded back at an angle as shown in FIG. 6, the user can use the front space of the leg as a practical use space, and can use the display device by utilizing the support area of the narrow area even for the main body of the large screen. You can get the advantages.

Hereinafter, a case in which the display device of the present invention and the wall mount mode are used will be described.

FIG. 7 further shows the case where the legs 4 and 5 are completely folded backwards in the state of FIG. 6. When the leg is completely folded as shown in FIG. 7, the wire is required to be longer in length due to a mismatch in the positional relationship between the center of rotation of the leg and the pulley as described above. Therefore, the main body 1 will be moved upward or the slider will be moved, which may be the case.

Thereafter, the folding stopper 94 is pressed to release the interlocking action between the first groove 91 and the folding stopper 94, and then the support part 22 is flipped backward. Here, when the support part 22 is flipped back, it moves to the position which the folding stopper 94 catches in the said 2nd groove 92. Then, as shown in FIG. 8, the main body 1 is completely folded, and the space occupied by the main body 1 is reduced. This state means not only the folding state of the display device but also the state when the display device is sold by the manufacturer. As such, the space occupied when the display device is moved is reduced, thereby allowing the display to be accommodated in the same space. The number of devices can be increased.

On the other hand, in a state in which the support portion 22 is completely folded backward, a predetermined fixing structure for fixing the folded support portion 22 in the folded state may be further provided. In the present invention, when the display device is fixed to the wall, the fastening member is inserted into and fixed to the support part 22.

For reference, FIG. 9 illustrates a relationship between the peripheral configuration of the folding stopper 94 and the stopper guide 9 in a state where the display apparatus is laid down.

10 illustrates a state in which the display device according to the present invention is hung on a wall.

Referring to FIG. 10, the base and / or leg is fixed to the wall by the fastening member 100. In addition to this, in this case, since the main body 1 can be moved up and down along the support portion 22, the user can conveniently adjust the position of the main body 1 without any change.

Another embodiment of the present invention will be described.

First, the wire may be made of metal, but may be made of plastic or fiber as long as it can support the weight of the body.

In addition, the pulley is for smoothly bending the extending direction of the wire, and it is not necessary that the pulley is necessarily used, and it is only necessary to have a large radius of curvature so that the extending direction of the wire is smoothly bent. However, it is true that the pulley is preferably applied because the pulley may not be generated by the use of the pulley. From this point of view, since the pulley is a part for changing the direction of extension and the fraud wire, it may be called a deflector.

In addition, the present invention provides a case in which two legs are provided, but the present invention is not limited thereto, and one leg or three legs may be used to obtain the same effects as the present invention.

In addition, in the present invention, in the state where the wire is not provided, a separate elastic device is built into the stand, the self-weight of the main body is supported by the device, the leg in a state in which the leg is moved forward or backward Embodiments to facilitate the support action of the body by it will also be possible. Of course, in this case, of course, it is more preferable that a separate position fixing structure for supporting the position of the legs is further provided.

The spirit of the present invention is not limited to the accompanying embodiments, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments included in the scope of the same idea by adding, changing, deleting, and adding components. Although it may be possible, this will also be included in the spirit of the present invention. In addition, although the components presented in any one of the above-described embodiments may be included in other components to suggest another embodiment, this is also included in the spirit of the present invention.

According to the present invention, there is an advantage that the space required for the installation of the display device is reduced by making the stand more slim.

In addition, the self-weight can be stably supported even for a large display main body, which is more convenient, and the area in which the display device is placed is variable, so that the user can obtain an advantage that the user can use it more conveniently according to a desired use state. .

In addition, while the general stand state and the wall mount state can be implemented simultaneously, the user can operate the display device in any state, which is convenient.
