The present invention relates to a display device, and more particularly, to a display device capable of stably supporting a load of a display main body while reducing a volume of a stand.

The display device is a device 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, an elastic device is built in which the display module can easily move its position while supporting its own weight. to be.

However, since the conventional elastic device uses a coil spring, there is a disadvantage in that the magnitude of the force to be applied is increased according to the extent to which the user moves the display device. In other words, the user can move the body with a small force up to a certain moving distance, but since the elastic force by the spring increases after exceeding a certain degree, the problem that it does not move unless a certain strong force is given It is. This is because the springs each have a spring constant (k) that is predefined, and the elastic force increases as the displacement (x) increases.

In order to solve such a problem, there is also proposed a technology that allows the user to conveniently move the main body by the built-in leaf spring in the holding portion of the stand, the elastic force maintained to some extent provided by the leaf spring. However, this conventional technique has a disadvantage in that the volume of the stand holding portion becomes large because the leaf spring is inserted into the body portion of the stand. In other words, as the volume of the support portion supporting the weight of the display main body increases, there is an inconvenience in packaging or moving the product, and the structure thereof is complicated.

The present invention is proposed to solve the above-mentioned problems, and proposes a display device that can support a small weight of the stand while moving the body of the main body while the weight of the display device is supported. do.

Display device according to the invention, the display body; A lifting member connected to the display main body and moving together; A holding portion for guiding the lifting movement of the lifting member; A base supporting the lower side of the support portion; A slider placed on the base and moving; A wire connected at one end to the elevating member and connected at the other end to the slider to provide a force for moving the slider during movement of the elevating member; And a spring that provides an elastic force when the slider moves.

According to the present invention, the volume of the stand of the display device may be reduced, the user may conveniently adjust the position of the main body, the movement may be convenient, and the volume of the packaging may be reduced.

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

1 is a rear perspective view of a display device according to the present invention, Figure 3 is an operating state of the display device shown in a state in which the holding portion is removed from the display device according to the present invention.

1 and 3, the main body 1 in which the display module is accommodated, the stand 2 supporting the weight of the main body 1, and the bottom surface of the stand 2 are placed on the bottom surface thereof. A base 5 supporting the weight of the stand 2 and the main body 1 is included.

The structure of the said stand 2 is demonstrated in more detail.

The stand 2 includes a rear fixing part 11 fixed to the rear surface of the main body 1, an inclined hinge 21 formed behind the rear fixing part 11, and the inclined hinge 21. Lifting member 22 is fastened to the rear of the, and the holding portion 23 for guiding the lifting action in the vertical direction of the lifting member 22 is included.

The elevating member 22 is to be guided by the movement of the support portion 23, for the smooth lifting operation, the support portion 23 is a lifting member ( It is preferable to guide the lifting and lowering action of 22).

In addition, a first pulley (also referred to as pulley and the same below) 24 is fixed to an inner surface of the support portion 23, and a wire 25 is wound around the outer surface thereof. One end of the wire is fixed to the elevating member 32.

The structure of the said base 5 is demonstrated in detail.

The base 5 has a hinge assembly 3 that directly supports the lower end of the stand 2, and on one side of the hinge assembly 3 a slider 51 and a guider for guiding the movement of the slider. 52 is provided. In addition, the other end of the wire 25 is connected to the slider 51, so that one end of the wire 25 is connected to the elevating member 22 and the other end is connected to the slider 51. . Of course, the first pulley 24 winds the wire 25 at least once, so that a force is generated in the direction in which the slider 51 is pulled when the lifting member moves downward. When the wire 25 and the slider 51 are described in more detail, the pulley 53 is connected to the slider 51. And the Weiser 25 is wound around the outer surface of the pulley 53. By providing the pulley 53, even if the left and right sides of the elevating member 22 are unevenly moved to the lower side in a state where the first pulleys 24 are provided one by one on both the left and right sides, the wire 25 is partially No burning occurs, and the pulley 53 is balanced in both directions.

In addition, the hinge assembly 3 is further provided with a stopper structure for stopping the support 23 at a predetermined angle to guide and support the rotational movement of the support 23.

The stopper structure includes a stopper guide 32 formed at both ends of the hinge assembly 3, grooves 33 and 34 formed on an outer circumferential surface of the stopper guide, and the grooves 33 and 34. A folding stopper 35 is provided, which is selectively inserted in and which stops the rotation of the support 23.

An operation associated with the wire 25 will be described with reference to FIG. 3.

1 and 3, the wire 25 has one end connected to the elevating member 22, and the other end connected to the slider 51, as described above.

In this state, when the user lowers the main body 1 downward, the elevating member 22 is lowered together, and the wire 25 is also pulled downward. Even if the wire 25 is pulled downward, since the first pulley 24 is fixed to the support 23 regardless of the movement of the elevating member 22, the first pulley 24 is connected to the end of the wire 25. The slider 51 is pulled.

Here, the wire 25 is a member lying inside the stand 2 and extends downward along the stand, and then the extension direction is changed toward the slider 51. To this end, the hinge assembly 3 is provided with a second pulley 31 to change the extension direction of the wire 25. Due to the connection structure of the wire 25, the slider 51 moves toward the second pulley 31 in a state of being guided by the guider 52.

Further, an elastic device for supporting the weight of the main body 1 is provided between the slider 51 and the guider 52.

FIG. 2 is a cross-sectional view taken along line II ′ of FIG. 1. Referring to FIG. 2, the spring 54, which is rolled in a circular shape with one end fixed to the guider 52, is located in front of the slider 51. It is provided at the end. Thus, when the slider 51 is pulled by the wire 25 and moved forward, the front end of the slider 51 moves in the direction in which the spring is unfolded in contact with the spring 54. At this time, the spring 54 provides the elastic force to the slider 51, the elastic force provided to the slider 51 acts as a force for supporting the self-weight that the main body 1 wants to move downward. Therefore, when the user moves the display device upward or downward, it is possible to move the main body 1 easily with little force.

Here, the spring 54 is exemplified as a spring spring, and the spring force always generates a certain constant elastic force regardless of the distance the slider 51 is moved by the spring. Thus, the user can adjust the height of the main body more conveniently.

On the other hand, the display device of the present invention is implemented in two cases, the state of the general stand and the wall mounted state hanging on the wall, which is the display device of the present invention shown in Figures 1 and 4 above the wall It demonstrates in detail with reference to the side view in a state.

Referring again to FIG. 1, first and second grooves 33 and 34 are formed on the outer surface of the stopper guide 32. Then, the folding stopper 35 selectively caught by the grooves 33 and 34, the jaw 36 formed on the outer circumference of the folding stopper 35, and the left and right movements of the folding stopper 35. A push spring 37 is provided which is interposed between the guide shaft 38 and the inner end of the folding stopper 35 and the guide shaft 38 to provide the folding stopper 35 with an outwardly directed elastic force at all times. .

First, when the user intends to use the display device of the present invention in the stand state, the folding stopper 35 is caught in the first groove 33. Then, since the folding stopper 35 is a component that is also hung on the support 23, the support 23 is not divided. In this state, when the user intends to use the display device of the present invention in the wall mount state, the folding stopper 35 is pushed inward. Of course, at this time, since the folding stopper 35 is supported by the push spring 37, a force that is always drawn out is generated.

The user pushes the folding stopper 35 inward, and then folds the stand 2 forward based on the drawing. At this time, the folding stopper 35 moves along the inner surface of the stopper guide 52. When the stand 23 is fully folded, that is, the wall mount state, the folding stopper 35 and the second groove 34 are aligned. The folding stopper 35 protrudes outward along the second groove 34. Once the folding stopper 35 is caught in the second groove 34, the stand 2 is fixed in the folded position without being unfolded again. In other words, it remains fully folded.

4 shows a display device which is in a wall mounted state, and then, both may be fastened using a predetermined fastening member 57 such as a screw or the like that penetrates the base 5 and the wall.

Even when the display device is mounted in the wall mounted state, the main body 1 may be moved with a constant elastic force in the vertical direction. Also in this case, the interaction between the slider and the guide and the elastic force applied by the spring act as a force for preventing the movement of the main body 1.

According to the present invention, the user can move the display body in a state where a constant elastic force is always provided. In addition, while the weight of the display device is supported, the volume of the stand becomes small. In particular, while the volume of the stand is reduced, it is more convenient because the same weight-bearing effect of the same body as in the prior art can be obtained. In one aspect, since the weight of the base becomes heavy and the weight of the stand becomes light, the possibility that the display device is turned over may be remarkably reduced.

The spirit of the present invention further includes the following examples.

First, the inclined hinge 21 is configured to allow the main body to rotate in the vertical direction. However, the present invention is not limited thereto, and any hinge configuration such as a swivel hinge, a portrait hinge, and the like, which enables three-dimensional overall movement, may be further interposed.

In addition, in the above-described embodiment, the pulley is for smoothly guiding the rotation of the wire, and the pulley is an article capable of free rotation. However, it is not limited to the pulley, although any article that guides the movement of the wire may be possible although it is not rotated. For this purpose, the pulley includes any article that guides the smooth movement of the wire. It will be understood as a configuration. However, by using the pulley, of course, the smooth movement of the wire is guided, of course, in the implementation of the present invention, of course, can be preferably applied.

In addition, the above-described embodiment is described as being operated in a state where one wire is installed, but is not limited thereto, and two or three or more may be installed. However, it is true that one wire is provided, one first pulley is provided, two second pulleys are provided, and one pulley is provided to balance the force in both the left and right directions.

In addition, when the main body is laid down in the display device of the present invention, a structure such as a folding stopper for fixing the main body is not essential, and the manufacturer may not selectively provide it. However, if the folding stopper structure is provided, the user can use the stand even in the wall mount state, so that the user's convenience is of course enhanced.

In addition, although the first pulley is installed in the support portion to guide the wire push / pull, the action by the first pulley is only for providing a force for pulling the slider when the lifting member is lifted. Therefore, it is not necessarily limited to a specific form such as a pulley, and any structure for changing the direction of force may be employed.

The spirit of the present invention is not limited to the embodiments described above, and those skilled in the art who understands the spirit of the present invention may further include other embodiments falling within the scope of the same idea by adding, changing, deleting, and adding components. It may be proposed, but this is also included in the spirit of the present invention. In addition, by including the components included in any one of the embodiments described above may be proposed in another embodiment, it will also be included in the spirit of the present invention.

According to the present invention, while the weight of the display device is supported, the volume of the stand is small, it is easy to move, and it is convenient when the user moves the position of the main body.

In addition, since the elastic force is provided by the spring operated in the main winding method, in the self-weight support of the display device, there is an advantage that the elastic force of the degree that offsets the self-weight of the display device can be constantly generated, thereby allowing the user to further There is an advantage that the display device can be used conveniently.
