[0001] STANDING DEVICE OF FLAT DISPLAY [0002]

The present invention relates to a stand of a display device. More particularly, the present invention relates to a stand of a display device which is capable of being applied to a main body in which images of various sizes are displayed with less restrictions, and which can provide a tilting function of a main body in which an image is displayed with a simple structure.

The present invention relates to a stand of a display device. A display device refers to a device that displays a video signal input from the outside. The display apparatus includes a monitor for displaying an image received from a computer, a television for displaying images and sound transmitted from the broadcasting station, and a device for displaying images input from the outside.

Conventional display devices are mainly composed of a Braun tube type, that is, a CRT type. In general, a CRT display device is constructed in a box type occupying a considerable volume. Therefore, when a user wants to store the display device in a home or an office, a floor, a living room floor and an office floor should be used with a separate pedestal.

However, as a result of the development of the technology, the thickness of the display device has been drastically reduced as the weight of the display device deviates from the CRT method and converted to a flat panel display device such as an LCD or a PDP.

The flat panel display device is installed by a wall-mounted type or a stand type. When the flat display device is installed in a wall-mounted manner, the wall-mounted device is coupled to a wall surface, and a flat-panel display device is mounted on the wall-mounted device.

When the flat panel display device is used as a stand type, the flat panel display device is mounted on the stand.

A stand used for installing a flat panel display device in a stand-up manner is composed of a base coupled with a neck neck coupled to a lower or rear surface of a main body to which an image is displayed, It is possible to stand upright even if it is thin.

The stand of the flat panel display device has the main function of the above-described standing function, and has a rotation function to rotate the display device body at a predetermined angle in some cases, and a tilting function to tilt the main body to display the image / RTI >

In particular, when a display device is used as a monitor of a computer, a flat panel type LCD monitor or the like has a narrow viewing angle of an image as compared with a conventional CRT type monitor. Therefore, Providing functionality is very important.

However, the tilting of the main body of the display device does not merely provide a function of adjusting the tilted angle of the main body, but it is necessary to maintain the main body that displays the image at an adjusted angle. Depending on the area of the front surface where the image is displayed, various sizes of products are available, and the weight is also proportional to the size.

In order to adjust the angle of the display device at a specific angle according to the weight of the main body, the magnitude of the frictional force provided inside each hinge portion must be changed.

1 is an example of a stand of a display device that provides a conventional tilting function.

The stand of the conventional display device shown in FIG. 1 is connected to the back surface of the main body 100 for displaying an image and includes a coupling part 210 having a knurling 212, a coupling part 210 and a shaft 230 A neck 220 coupled thereto and a base 240 supporting the neck 220 and dispersing the load of the display device and the load due to the load on the ground.

The shaft 230 penetrates the knurling portion 220 of the coupling portion 210 and the neck 220 and functions as a rotation shaft. A proper frictional force acts between the outer surface of the shaft 230 and the inner surface of the knurling 212 and the tilting angle of the main body 100 can be maintained by this frictional force.

However, the shape of the coupling part 210 is limited for the coupling of the main body 100 and the coupling part 210 and the insertion of the knurling part 212 and the shaft 230 of the coupling part 210. However, The width of the stand is large.

In addition, depending on the size and load of the main body mounted on the stand, the frictional force between the shaft 230 and the coupling knurling 212 must be adjusted.

If the frictional force between the shaft 230 and the coupling knurling 212 is set large when the main body 100 is small in size, the user must rotate the main body 100 with a force larger than the frictional force, The user can feel the inconvenience.

In addition, if the frictional force is small enough not to support the weight of the main body 100, the main body 100 can not be fixed at a specific angle.

Therefore, a stand corresponding to the size and weight of the body must be designed, respectively, such that an appropriate amount of frictional force acts between the shaft 230 and the coupling knurling 212.

Such separate manufacture of a stand corresponding to the size and weight of the main body 100 causes an increase in cost.

It is an object of the present invention to provide a stand of a display device capable of providing a tilting function of a main body of a display device while being simple in configuration and capable of being applied to a main body of various sizes, .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Like reference numerals designate like elements throughout the specification.

3 is a perspective view illustrating a coupling relationship between the housing 330, the roller 350, the center shaft 320, and the bracket 310, which is viewed from above. FIG. 3 is an exploded perspective view of an embodiment of the display device according to the present invention. to be.

In the embodiment shown in Figs. 2 and 3, the stand of the display apparatus according to the present invention includes a housing 330 as a rotation axis for tilting the main body in which an image is displayed. The housing 330 serves as a hinge shaft having a rotating function to enable tilting of the main body in the stand of the display device.

The housing 330 has a flow hole formed therein so that the center shaft 320 can be rotated at a predetermined angle or more in a state where the center shaft 320 is penetrated. The center shaft 320 of the housing 330 penetrates the flow hole and is fastened to the base 340.

The flow hole may be formed to have a size such that the rotation of the housing 330 is not disturbed by the center shaft 320 when the housing 330 is rotated. Since the center shaft 320 can flow inside the flow hole, the flow hole plays a role of limiting the rotation range of the housing 330. That is, the tilting range of the main body is proportional to the size of the flow hole.

In the embodiment shown in FIG. 3, the flow holes are configured in the form of slots 334. The center axis 320 can flow at a predetermined angle within the elongated hole.

3, the flow hole is formed in the shape of an elongated hole, so that the central axis 320 can flow only in the longitudinal direction of the elongated hole 334, The rotation can be rotated only in a certain direction, and the lateral movement is limited.

In addition, in the embodiment according to the present invention, the housing 330 is coupled to the main body by the bracket 310 which is fastened to the housing 330. The bracket 310 may be inserted into an insertion groove (not shown) formed in the back surface of the main body or may be coupled to the main body by inserting a bolt or the like into the bolt hole 312 formed in the bracket 310.

In the embodiment of the present invention, the housing 330 is coupled to the base 340 by the center shaft 320.

The center shaft 320 extends through the base 340 and is threaded at the lower end of the center shaft 320. The screw shaft 346 is screwed on the bottom surface of the base 340, (340).

At this time, the frictional force at the contact surface between the housing 330 and the base 340 is determined according to the strength of tightening the screw 346 to the lower end of the center shaft 320.

That is, in the case where the size and weight of the main body are large, the fastening force by the screw 346 is increased so that the frictional force enough to maintain the specific tilting angle acts on the contact surface between the housing 330 and the base 340 .

The portion of the housing 330 contacting the base 340, that is, the lower portion thereof, is preferably curved.

The shape of the contact portion of the base 340 contacting the housing 330 may also be curved to correspond to the shape of the housing 330.

Since the housing 330 of the present invention shown in FIG. 2 is formed in a cylindrical shape, it is preferable that the contact portion of the base 340 of the display device according to the present invention has a concave curved surface, that is, a depression 348 Do.

Further, in the embodiment of the display device according to the present invention, it is preferable that a friction pad is further provided between the housing 330 and the depression 348 of the base 340.

The display device stand is generally made of a plastic resin material. When a rotary part for tilting the main body is used for a long period of time, a chip may be generated due to friction. Here, a chip means a dust or the like generated when plastic parts are abraded by friction, and if such a chip accumulates between two parts performing relative movement, the frictional force can be greatly increased.

If the friction force is unnecessarily increased, a user needs a larger operating force for tilting the main body, so that a reliable tilting function can not be provided.

Conversely, the generation of such a chip implies wear of the component, so that the clearance between the two parts that move relative to each other can be increased beyond the allowable tolerance. The clearance above the tolerance means that the body and the stand on which the image is displayed, i.e., the embodiment of the present invention, can not provide a frictional force between the housing 330 and the depression 348 of the base 340, The tilting angle of the main body can not be maintained.

Consequently, both increased frictional forces due to abrasion of the contact area and reduced frictional forces can not provide a reliable tilting function.

Therefore, it is preferable that the friction pad 335 shown in FIG. 2 is made of a material having less abrasion resistance to friction than the material of the housing 330 and the base 340.

As the material of the friction pad 335, rubber, urethane or the like may be possible. In the case of rubber or urethane, a certain degree of elasticity can reduce the clearance caused by abrasion between parts to some extent, and it provides an appropriate frictional force to help maintain the body tilting angle. Due to the appropriate frictional force and surface material, the user can tilt the main body with a soft operating feel.

The shape of the friction pad 335 preferably has a shape corresponding to the shape of the surface of the housing 330 and the depression 348 of the base 340.

The friction pad 335 is formed with a through hole through which the center shaft 320 passes.

Unlike the elongated hole 334 formed in the housing 330, the through hole may have a size enough to allow the center shaft 320 to pass therethrough.

As already described, the central axis 320 is fastened by screws 346 at the lower surface of the base 340. On the other hand, the upper end of the center shaft 320 is fastened by a fixing means for allowing the housing 330 to rotate in a state of being in contact with the base 340.

In the embodiment of the present invention, the fixing means is a roller 350 inserted into the housing 330. The housing 330 is provided with a receiving space 332 through which the roller 350 can be received.

In the embodiment according to the present invention, the roller 350 is cylindrical in shape, similar to the shape of the housing 330. The inner surface shape of the accommodating space 332 of the housing 330 in which the roller 350 is accommodated preferably corresponds to the outer surface shape of the roller 350 and the portion contacting the roller 350 is curved Do.

The roller 350 is also formed with a through hole through which the center shaft 320 passes, and the upper end of the center shaft 320 is formed of a rivet 322.

The housing 330 housing the roller 350 and the roller 350 and the base 340 can be rotated by the rivet 322 formed at the upper end of the center shaft 320 and the screw 346 coupled to the lower end, Can be fastened simultaneously by the central axis 320.

The base 340, which is fastened to the housing 330 by the center shaft 320, is generally made of a plastic material. The base 340 disperses the load of the main body on the ground, and performs the function of supporting the main body.

The center shaft 320 coupled to the bottom surface of the base 340 by the screws 346 through the base 340 can be significantly distorted or deformed in the vicinity of the penetration of the base 340 due to the load of the main body. The same load acts as the motor.

Therefore, it is preferable to add a metal plate 344 to the bottom surface of the base 340. By adding the metal plate 344, the load or torsion caused by the central axis 320 can be uniformly dispersed throughout the base 340, and the rigidity of the base 340 itself can be reinforced.

In addition, when the housing 330 is mounted on the flat plate-shaped base 340, the height of the display device may be low, so that the contact portion of the base 340 with the housing 330 may be formed to be raised have. The height of the display device can be compensated by the raised height.

It is also preferable to add the reinforcing member 342 for the same reason as that for adding the metal plate 344 to the lower surface of the base 340 in the raised portion.

The lower surface of the housing 330 or the lower surface of the friction pad 335 is formed on the upper portion of the reinforcing member 342 and the depressed portion 348 is formed. (Not shown) is formed.

2, the stand of the display apparatus according to the present invention includes an insertion groove 336 for mounting the bracket 310 on the housing 330, and a bracket (not shown) 310), and then fastened by bolts or the like. The fastening holes 337 and 317 (see FIG. 2) are formed in the housing 330 and the bracket 310 for fastening by bolts.

In addition, the bracket 310 has a second fastening hole 312 for engaging with a body of the image. When the bracket 310 is coupled to the rear surface of the main body, the bracket 310 and the rear surface of the main body are coupled with bolts passing through the second fastening holes 312.

4 is a side cross-sectional view of a stand of a display device according to the present invention. 4 (a) and 4 (b) show different angles of rotation of the bracket 310 on which the body for displaying an image is mounted. 4, the roller 350, the friction pad 335, and the base 340 are coupled to the center shaft 320 by a screw 346. As shown in Fig.

However, the housing 330 housing the roller 350 in the accommodation space 332 formed at the center rotates around the roller 350 as a rotation axis. At this time, frictional force acts between the housing 330 and the friction pad 335 (when the friction pad 335 is included) and between the housing 330 and the roller 350, so that the bracket 310 is maintained at a constant angle .

As described above, the stand of the display device according to the present invention includes a center shaft 320, which is a means for supporting the weight of the main body and fastening the respective parts, is fastened by screws 346 at the lower surface of the base 340 do.

The fastening force by the screw 346 will eventually be proportional to the frictional force acting on the housing 330, and the frictional force must be adjusted according to the load of the main body. Therefore, if the strength of the fastening of the screw 346 coupled to the center shaft 320 at the bottom of the base 340 is adjusted according to the size and weight of the body, various sizes of bodies can be mounted.

Since the fastening force of the screw 346 must be maintained constant, it is possible to prevent the loosening by attaching a washer together with the screw 346 or mounting a plurality of screws.
