Stand for flat panel display {STAND FOR FLAT PANNEL DISPLAY}
[26] The present invention relates to a stand for a flat panel display, and more specifically, to a stand that can adjust the left, right, up and down tilt angles of the display.
[27] As an image display device, a monitor using a cathode ray tube has been widely used for a long time. Recently, the screen of such a cathode ray tube tends to be larger, but as the screen becomes larger, the cathode ray tube itself must also be enlarged. Large monitors not only occupy a large desk space, but the electromagnetic field emitted from the cathode ray tube is known to adversely affect the human body.
[28] Therefore, in order to replace the conventional monitor using a cathode ray tube, various liquid crystal display devices were developed. The liquid crystal display device is supported by the support in the form of a stand, but the stand cannot adjust the tilting angle of the liquid crystal display device. In order to adjust the tilt angle of the display, for example, U. S. Patent No. 5,854, 735 to Cheng, issued December 29, 1998, has been proposed.
[29] As shown in FIG. 1, the liquid crystal display device disclosed in the Cheng patent has a liquid crystal display device 2, a stand 4 supporting the liquid crystal display device 2, and a liquid crystal display device and a stand connected thereto. And a hinge portion 6 having a pivot axis capable of adjusting the angle of the liquid crystal display device up and down.
[30] According to the Cheng patent, the weight of the stand must be quite heavy to stably support the liquid crystal display. In addition, the liquid crystal display and the stand are integrally assembled and marketed by the manufacturer due to the difficulty of assembly. Therefore, it is rather inconvenient to use a flat panel display with a stand.
[31] For example, if the display is to be moved, the stand must also move with the display. In addition, when it is necessary to store the display, a wide storage place is necessary because the stand must be stored with the display mounted.
[32] Accordingly, an object of the present invention is to solve the above-mentioned conventional problems, and in particular, to provide a stand for a flat panel display that can easily separate the display from the stand supporting the display.

[33] In order to achieve the above and other objects of the present invention, according to one aspect of the present invention, there is provided a stand for supporting a flat panel display, comprising: a hinge portion attached to a rear surface of the display and having a pivotable leg; A holder for accommodating the legs of the hinge portion; Provided is a stand for a flat panel display including a base for rotatably supporting the holder horizontally.
[34] The hinge portion has a bracket, the portion of which is fixed to the back of the display, and the legs of the hinge portion are pivotally fixed to the other portion of the bracket. The other portion of the bracket is formed with a plurality of guide grooves along its circumferential surface.
[35] The leg has flat surfaces formed at both ends thereof, and includes a compression spring at the end having the flat surface formed thereon, and a stopper which is constantly pressed toward the bracket by the compression spring, and the leg is fitted with the compression spring and the stopper fitted thereto. A plurality of washers and nuts are fastened to the lower brackets, and protruding from the brackets.
[36] The stopper preferably has an opening having a shape corresponding to the flat surface such that the stopper is fitted to the end where the flat surface of the leg is formed so as not to rotate relatively. The stopper includes a protrusion disposed in a guide groove formed on the circumferential surface of the bracket.
[37] The holder has a front cover, a front and rear support portion disposed inside the front cover, and a rear cover disposed on the rear surface of the front cover to fix the front and rear support portions. In addition, the holder is mounted to the front support portion, and additionally provided with a stopper for fixing the legs of the hinge portion.
[38] The stopper includes a pressing portion projecting up to the front cover, a engaging portion engaging with the fixing groove of the leg, a pair of protrusions having an arm for pivotally connecting the stopper to the front support portion, and protruding downward from the pressing portion. An elastic spring is provided.
[39] Hereinafter, a stand for a flat panel display according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
[40] 2A to 2D are perspective views schematically showing a state of use of a stand for a flat panel display according to an embodiment of the present invention, wherein the stand according to the present invention is attached to the rear surface of the display 20 and pivots a leg. And a hinge portion 30 for supporting the holder 30, a holder 40 for accommodating the legs of the hinge portion 30, and a base 60 for rotatably supporting the holder 40.
[41] 3 to 5 and 10, the hinge portion 30 will be described in detail. The hinge portion 30 has a bracket 32, a portion of which is fixed to the back of the display, and a leg 34 pivotably fixed to another portion of the bracket 32. The other portion of the bracket 32 is formed with a plurality of guide grooves (32a, 32b) along its circumferential surface.
[42] Leg 34 has a flat surface formed at both ends 34a, and a stopper which is always pressed toward the bracket 32 by the compression spring 302 and the compression spring 302 at the end where the flat surface is formed. 304 is provided. Then, the leg 34 is inserted into the bracket 32 with the compression spring 302 and the stopper 304 fitted, and a plurality of washers 308 and nuts 310 are fastened to portions protruding from the bracket. .
[43] The stopper 304 has an opening (not shown) having a shape corresponding to the flat surface so as to be relatively rotatably fitted to an end where the flat surface of the leg 34 is formed. The stopper 304 is provided with a pair of projections 306 and 306a disposed in the guide grooves 32a and 32c formed on the circumferential surface of the bracket 32.
[44] As described above, the stopper 304 is always pressed toward the bracket 32 with the projections 306 and 306a fitted in the guide grooves 32a and 32c. In the state where the projections 306 and 306a of the stopper 304 are fitted into the guide grooves 32a and 32c, the legs cannot be pivoted with respect to the hinge portion by the stopper which is inserted into the end portion 34a of the leg so as not to rotate relatively. . Leg 34 of the hinge portion 30 is inserted and fixed to the holder 40 to be slidably as shown in FIG.
[45] Installing the guide grooves on the circumferential surface of the bracket to which the ends of the legs are coupled may be somewhat limited due to the size of the bracket. In order to solve this, as a modification (see FIG. 11), a plurality of holes 32a 'spaced at regular intervals are formed in the bracket 32' to which the ends of the legs are coupled, and a stopper 304 'is formed. Has a pair of projections having a size that can be inserted into this hole. In addition, the stopper 304 'is formed in a hollow cylindrical shape, and a plurality of grooves are formed on the outer circumferential surface of the cylindrical portion so that a user can easily operate the stopper. According to the above-described configuration, even if the leg is adjusted to any tilting angle, since the projection always engages with the hole, the leg is prevented from slipping by the weight of the video display device during use.
[46] The holder 40 is disposed on the front cover 42, the front and rear supports 44 and 46 disposed inside the front cover 42, and the rear surface of the front cover 42, as shown in FIG. 2A. And a rear cover 48 that secures the front and rear supports 44, 46. The anterior and posterior supports 44, 46 are preferably made of metal. The reason for this is because the holder 40 is coupled to the base 60 by the connector 50 as described below, and it is desirable to increase the durability of the coupling portion of the holder.
[47] In addition, the holder 40 is attached to the anterior support 44 and has a stopper 49 for fixing the legs 34 of the hinge 30. The stopper 49 coupled to the anterior support 44 is a pressing portion 49a protruding up to the front cover 42, a locking portion 49b engaging with the fixing groove 342 of the leg 34, and a stopper 49. A pair of protrusions 49c having an arm for pivotally connecting to the front supporter 44, and an elastic spring 49d projecting downward from the pressing portion 49a.
[48] 8 and 9, the front support 44 of the holder 40 is pivotable about a support plate 142 on which the elastic band 344 of the leg 34 is seated and one end of the stopper 49. A boss 144 for supporting, an opening 146 through which the stopper 49 can enter and exit, and a guide 148 for guiding the leg 34 are provided. The elastic band 344 prevents the leg 34 from being pushed backward by the weight of the display when the display 20 is used without mounting the holder as shown in FIG. 2C. In addition, the elastic band 344 prevents the vibrations applied to the holder from the outside when directly mounted to the holder 40 to be transmitted directly to the display.
[49] In addition, the anterior support 44 has a bracket 144a to support one end of the stopper 49 and to facilitate attachment and detachment of the stopper. This bracket 144a is fixed to the rear surface of the anterior support by screws 144b.
[50] According to the above-described configuration, the stopper 49 can pivotally move around the brackets 144 and 144a as shown in FIG. 7. More specifically, if pressure is applied to the pressing portion 49a protruding to the front surface of the front cover 42 (see FIG. 6), the locking portion 49b of the stop portion 49 will be moved to the right side when viewed in FIG. 7. Move. Then, when the pressure applied to the pressing portion 49a is released, the locking portion 49b returns to its original position due to the spring force of the spring 49d.
[51] The stand for flat panel displays according to the invention also comprises a connector 50 connecting the holder 40 and the base 60. The connector has an opening (not shown) formed in the center of the main body, and a connector disposed through the opening. Both ends of the connector are firmly fixed to the base 60 by screws. The connector has a head having a diameter larger than the diameter of the opening at the upper and lower ends so as not to be released from the opening after being inserted into the opening. The head formed at the upper end is disposed in the slit formed on the bottom surface of the front case 42 and the front support portion 44, the holder 40 can rotate left and right about it.
[52] Referring to FIG. 9, the process of mounting the leg of the hinge portion to the holder is described. The leg 34 of the hinge portion moves along the guide portion 148 of the front support portion 44 to the locking portion 49b of the stopper 49. Then, the user presses the pressing portion 49a of the stopper 49 to move the locking portion 49b. When the locking portion 49b moves, the elastic band 344 of the leg 34 is seated on the support plate 142 of the rear support 44. Then, when the stopper 49 is restored to its original position, the locking portion 49b is engaged with the fixing groove 342 of the leg 34. When the engaging portion 49b is coupled to the fixing groove 342 of the leg 34 in this manner, the display is not separated from the holder.
[53] If the display is to be moved or stored, the display can be detached from the holder by a simple operation, that is, by operating the stop 49 (see FIG. 2D). In this case, referring to FIG. 10, the projections 306 and 306a of the stopper 304 are inserted into the fixing groove 32b and the fixing hole 32d of the bracket 32. Therefore, since the leg is fixed to the display, the leg can be used as a moving handle.
[54] According to the above-described configuration, the flat panel display stand according to the present invention has a very simple configuration for adjusting the tilting angle of the display compared with the conventional configuration.
[55] In addition, since the stand for a flat panel display according to the present invention has a structure in which the display and the stand can be easily detached, the display can be easily moved or stored.
