DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below so as to explain the present invention by referring to the figures. Hereinafter, a display apparatus according to an exemplary embodiment of the present invention will be described as referring to drawings. As shown in FIGS. 1 and 2, a display apparatus 10 according to the present invention 10 comprises a display body 20, a connecting member 30 and a base 40. The connecting member 30 is combined with the display body 20 at an upper end part thereof and has a swivel part 31 at a lower end part thereof. The base 40 comprises a swivel supporter 47 supporting the swivel part 31 to be rotatable. The display apparatus 10 further comprises a bracket 70 combined with the base 40 to prevent the connecting member 30 from separating from the swivel supporter 47. The display apparatus 10 may comprise a first friction member 60 disposed between the bracket 70 and the lower base 45 to slide on the bracket 70 and the lower base 45 while the connecting member 30 rotates. Further, the display apparatus 10 may comprise a second friction member 50 having various thicknesses and disposed between the connecting member 30 and the lower base 45 to slide on the connecting member 30 and the lower base 45 while the connecting member 30 rotates. Also, the display apparatus 10 may comprise a rotation control unit 80 to control the connecting member 30 to rotate in a predetermined angle. As shown in FIG. 1, the display body 20 comprises a display 21 and a casing 23 accommodating the display 21. The display body 20 is combined with the connecting member 30 and supported by the base 40. The display 21 may be provided as a liquid crystal display (LCD), a plasma display panel (PDP), or etc. As shown in FIG. 2, the connecting member 30 is combined with the display body 20 at the upper end part thereof and comprises the swivel part 31 at the lower end part thereof. The connecting member 30 is of a cylinder shape, but may be of other shapes such as an oval tube shape or a polygonal tube shape. The connecting member 30 may be made of a plastic material or etc. As shown in FIGS. 2 and 3, the swivel part 31 is disposed at the lower end part of the connecting member 30 and rotatably supported by the swivel supporter 47 of the base 40. The swivel part 31 is combined with the bracket 70 through a screw or the like, thereby being prevented from separating from the swivel supporter 47. The swivel part 31 comprises a step part 33 contacting with a top surface of the swivel supporter 47 or the second friction member 50 to generate friction when rotating. The base 40 comprises the swivel supporter 47 to support the swivel part 31 to be rotatable. The base 40 comprises the lower base 45 and an upper base 41. The lower base 45 contacts with an installation surface and is not seen from the outside and the upper base 41 is combined with the lower base 45 to be seen from the outside. The upper base 41 has an oval shape. The base 40 is combined with the stand 30 to support the display body 20. As shown in FIG. 2, the upper base 41 is combined with the lower base 45 to make an oval appearance. The upper base 41 has an upper through hole 43 where the lower end part of the connecting member 30 is inserted. The upper base 41 may be made of an attractive plastic plate or a metal plate to make its appearance look appealing. As shown in FIGS. 2 and 3, the lower base 45 comprises the swivel supporter 47 to rotatably support the swivel part 31. The lower base 45 is not seen from the outside and contacts with the installation surface. The lower base 45 has a plate shape and protrudes or caves in so as to reinforce its strength. The center portion of the lower base 45 is protruded and is off the installation surface. The base 40 does not rotate while the display body 20 rotates. The lower base 45 may be combined with the upper base 41 through a screw, a hook or the like. The lower base 45 may have a wide bottom to stably support the display body 20. The upper base 41 can be improved in its appearance regardless of the swiveling parts since the rotatable swivel part 31 is combined with the lower base 45 and covered with the upper base 41. As shown in FIGS. 2 and 3, the swivel supporter 47 supports the swivel part 31 to be rotatable on the lower base 45. The swivel supporter 47 has a predetermined bent shape to support load of the display body 20. The second friction member 50 is disposed between the connecting member 30 and the lower base 45 to slide on the connecting member 30 and the lower base 45 while the connecting member 30 rotates. The second friction member 50 has various thicknesses and contacting areas so as to control a friction force depending on the load of the display body 20. The first friction member 60 is disposed between the bracket 70 and the lower base 45 to slide on the bracket 70 and the lower base 45 while the connecting member 30 rotates. The first friction member 60 has a shape corresponding to bent shapes of the bracket 70 and the lower base 45. The first friction member 60 comprises a protrusion through groove 61 through which a protrusion 81 (to be described later) passes through. The first friction member 60 and the second friction member 50 are preferably made of acetal resin, which is excellent in wear resistance, has good strength and is excellent in friction related sound characteristics when the connecting member 30 rotates as compared with plastics or ABS resin. The friction force may be controlled by adjusting the thicknesses and the contacting areas of the first friction member 60 and the second friction member 50 considering the size, the weight and the like of the display body 20. The swivel portion of the display body 20 is combined with the lower base 45, thereby making the base 40 slim. Also, one of the first friction member 60 and the second friction member 50 may be formed integrally with the lower base 45. The bracket 70 is combined with the lower end part of the connecting member 30 through a coupling means under the base 40 to prevent the connecting member 30 from separating from the swivel supporter 47. The coupling means comprises a screw, a snap ring or a pin. The bracket 70 is combined with the swivel part 31 of the connecting member 30 when the base 40 is combined with the first friction member 60 and the second friction member 50, so that the friction force can uniformly be generated according to the rotation. The bracket 70 has a plate shape and is bent corresponding to the shape of the first friction member 60. As shown in FIG. 3, the rotation control unit 80 comprises a protrusion 81, a protrusion guide groove 83 and the protrusion through groove 61. The protrusion 81 is protruded from the lower base 45 toward the bracket 70 and the protrusion guide groove 83 is formed in the bracket 70 to receive the protrusion 81. Further, the protrusion through groove 61 is formed in the first friction member 60 and the protrusion 81 passes therethrough. Accordingly, the connecting member 30 may be controlled to rotate in the range of a predetermined angle. The connecting member 30 rotates in the range of 0� to 90�, but may rotate within the range of 180� given the corresponding change in the length of the protrusion guide groove 83 and/or the protrusion through groove 61. The protrusion 81 is protruded from the lower base 45 toward the bracket 70. The protrusion 81 is provided singularly or plurally and bent from the surface of the lower base 45 The protrusion guide groove 83 is formed in the bracket 70 to receive the protrusion 81. The protrusion guide groove 83 may be penetrated or caved-in. Alternately, the protrusion 81 may be formed in the bracket 70 and the protrusion guide groove 83 may be formed in the lower base 45. The protrusion guide groove 83 is a longer than the protrusion through groove 61 in a rotating direction. Accordingly, when the connecting member 30 is rotated in the clock-wise direction beginning from the state shown in FIG. 4A, the protrusion 81 does not contact the end portion A of the protrusion through groove 61 of the first friction member 60 until the state shown in FIG. 4B is reached. Upon further rotation, the protrusion 81 contacts the end portion A of the protrusion through groove 61 and thus, the first friction member is prevented from further rotation. The bracket 70 however further rotates until reaching the state as shown in FIG. 4C. Similar operation follows in the other rotating direction. In order for the first friction member 60 to rotate in unison with the bracket 70 (for the case where the protrusion 81 does not contact either end portions of the protrusion through groove 61), the frictional force between the bracket 70 and the bottom surface of the first friction member 60 should be greater than the frictional force between the bottom surface of the lower base 45 and the top surface of the first friction member 60. Therefore, when the connecting portion 30 is rotated in the state in which the protrusion 81 contacts either end portions of the protrusion through groove 61, the frictional force applied against the rotating force will be greater than the case in which the protrusion 81 does not contact either of the end portions. There are various known ways to cause various different frictional forces to exist between the surfaces such as shape, size, material and treatment of the contacting surfaces. Furthermore, the length of the protrusion through groove 61 in the rotating direction may be adjusted to control the friction force. Hereto, the present embodiment has been described with a large-sized display apparatus as an example, but may be employed in a small-sized display apparatus. The swiveling process of the display apparatus 10 according to the present invention will be described by referring to FIG. 4. First, the combining process of the display apparatus is as follows. The lower base 45 is seated on the installation surface and the second friction member 50 is disposed thereon. Then, the lower base 45 is combined with the upper base 41 through a screw or the like. Next, the connecting member 30 is inserted through the upper through the hole 43 of the upper base 41 to contact the second friction member 50. The end portion of the connecting member 30 protruded toward the lower base 45 passes through the first friction member 60. Then, the bracket 70 is combined to the connecting member 30. Thereafter, the display apparatus body 20 is combined with the connecting member 30. As described above, the first friction member 60 and the second friction member 50 may be combined with each other without an additional coupling means, and thus the configuration becomes simplified and assembling and disassembling processes become convenient. The disassembling process is performed in the reverse order of the combining process, and thus detailed description thereof will be omitted. According to the present invention, when the display body is swiveled, a connecting member is combined with the lower base by using a bracket 70 in such a manner so as to allow the lower base 45 to remain stationary. Thus, the lower base 45 has a wide area to stably support the display body 20 and furthermore, the connecting member 30 and the bracket 70 can be made relatively small, thereby simplifying the configuration and reducing cost. Further, the upper base 41 may be designed substantially independent of the size or shape of the lower base and/or connecting member and the bracket, thereby allowing pursuing of attractive and slim appearance. Also, the first friction member or the second friction member slides, so that the display body may smoothly rotate. As described above, the present invention provides a display apparatus which has a good appearance and rotates stably and smoothly. It will be apparent to those skilled in the art that various modifications and variation can be made in the present invention without departing from the spirit or scope of the invention. Thus it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
