DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to 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 described below explain the present invention by referring to the figures.

As shown in FIGS. 2 and 3, a display apparatus according to a first embodiment of the present invention comprises a display body 10 displaying a picture, a stand 100 placed on a surface such as a table, a hinge assembly 30 provided between the stand 100 and the display body 10 and supporting the display body 10, and a body bracket 20 detachably engaged to a rear of the display body 10 and engaged to the hinge assembly 30.

The display body 10 has a thin LCD panel mounted thereon, a plurality of first screw holes 11 corresponding to second screw holes 21 (to be described later) of the body bracket 20, and a pair of projection holders 15 corresponding to engaging projections 25 (to be described later) located in an upper part of the body bracket 20. The locations of the first screw holes 11 and the second screw holes 21 are in accordance with the VESA FDMI standard, so that various kinds of arm stands (not shown) that meet the VESA FDMI standard can be connected.

The body bracket 20 has the second screw holes 21 corresponding to the first screw holes 11 of the display body 10, that engage the first screw holes by first screws 23. The body bracket 20 also has a pair of engaging projections 25 that correspond to the projection holders 15 of the display body 10, and third screw holes 28 located on a projection part 27, which is located in the center of the body bracket 20, and corresponds to a pivoting bracket 41 of a pivoting hinge 40 (to be described later). Second screws 29 engage the pivoting hinge 40 and the projection part 27 using the third and fourth screw holes (28 and 42 respectively).

The hinge assembly 30, as shown in FIGS. 3 through 6, includes: a tilting hinge 60, provided between the display body 10 and the stand 100 to tilt the display body 10 relative to the stand 100; a pivoting hinge 40, provided between the display body 10 and the tilting hinge 60 to pivot the display body 10 relative to the stand 100; and a swiveling hinge 80, provided between the stand 100 and the tilting hinge 60 to swivel the display body 10 relative to the stand 100.

The pivoting hinge 40 enables the display body 10 to pivot relative to the stand 100. In other words, the pivoting hinge 40 enables the display body 10 to rotate around a pivoting axis 46.

The pivoting hinge 40 includes a pivoting bracket 41 that engages the body bracket 20, and pivotably engages a pivoting support bracket 51. The pivoting support bracket 51 is also engaged to a tilting bracket 61 of the tilting hinge 60. A pivoting shaft 45 has an approximately circular cross section, and projects from the pivoting bracket 41 toward the pivoting support bracket 51. A pivoting shaft accommodating part 54 has an opening therethrough to allow the pivoting shaft 45 to be inserted into the pivoting support bracket 51 and to pivot. A snap ring 49 engages an end part of the pivoting shaft 45 to securely, but pivotably, engage the pivoting bracket 41 with the pivoting support bracket 51.

According to one aspect, the pivoting bracket 41 is approximately cylindrical, and includes fourth screw holes 42 that correspond to the third screw holes 28 of the body bracket 20, and are engaged by the second screws 29. The pivoting bracket 41 also has a ball guide part 43 that is a recess in the shape of a circular arc of predetermined angle, corresponding to a ball flange 55 (to be described later) provided in the pivoting support bracket 51, to guide a ball 56 of the ball flange 55.

The ball guide part 43 is approximately a circular arc of about 90°, centered around the pivoting shaft 45. The ball guide part 43 has a rotation restraining part 44 at both ends to restrain the ball 56 of the ball flange 55 from moving outside of the ball guide part 43. The rotation restraining parts 44 are deeper recesses than the ball guide part 43.

The pivoting support bracket 51 is approximately cylindrical, and has a plurality of fifth screw holes 52 formed corresponding to sixth screw holes 62 (to be described later) of the tilting bracket 61. The pivoting bracket 51 is engaged both by third screws 53, and the ball flange 55, which is provided eccentrically from the pivoting axis 46 and corresponds to the ball guide part 43 of the pivoting bracket 41.

The ball flange 55 engages a ball flange screw hole 59 located in the pivoting support bracket 51, and having an internal thread. The ball flange 55 additionally has the ball 56, which is guided by the ball guide part 43; a coil spring 57, that engages the ball 56 to push the ball 56 toward the ball guide part 43; and an adjusting screw 58 that engages the coil spring 57 and the internal thread of the ball flange screw hole 59, and is used to adjust an elastic force of the coil spring 57 pushing on the ball 56.

By rotating the adjusting screw 58 to adjust the depth, the elastic force by which the coil spring 57 pushes the ball 56 is adjusted and thus a friction force generated between the ball 56 and the ball guide part 43 on pivoting is adjusted. When the ball 56 is accommodated in the rotation restraining parts 44 provided in the both ends of the ball guide part 43, the display body 10 is able to maintain an angle of about 0° or 90°. When beginning to pivot from one of these fixed positions, a force of predetermined magnitude must be applied to enable the ball 56 to escape the rotation restraining part 44.

The ball guide part 43 is a circular arc of about 90° in the above embodiment, but may be a circular arc of approximately 180° or more.

An end part of the pivoting shaft 45 has a taper part 47 so that the snap ring 49 can push the pivoting support bracket 51 engaged with the pivoting shaft 45 toward the pivoting bracket 41. A sectional diameter of the taper part 47 is smallest at a location closest to the pivoting bracket 41, and increases as the distance from the pivoting bracket 41 increases, so that when the snap ring 49 is pushed onto the taper part 47, the pivoting support bracket 51 engages the pivoting bracket 41.

The pivoting bracket 41 pivots relative to the pivoting support bracket 51 centering around the pivoting shaft 45, and pivoting is constrained to a range of about 0° to 90° by the ball flange 55 and the ball guide part 43. According to one aspect, the pivoting bracket 41 and the pivoting support bracket 51 are made of brass, to generate an appropriate friction force when the pivoting bracket 41 pivots relative to the pivoting support bracket 51. According to another aspect, the pivoting bracket 41 and the pivoting support bracket 51 are made of plastic, to generate an appropriate friction force when the pivoting bracket 41 pivots relative to the pivoting support bracket 51.

A taper of the taper part 47, to which the snap ring 49 is engaged, can be modified to adjust the friction force. That is, as the taper of the taper part 47 is increased, the snap ring 49 pushes the pivoting support bracket 51 toward the pivoting bracket 41 with greater force, to thereby increase the friction force. Also, by adjusting the adjusting screw 58 of the ball flange 55, a friction force between the ball 56 and the ball guide part 43 can be adjusted.

Thus, the display body 10 pivots around the pivoting shaft 45, and by adjusting the adjusting screw 58 of the ball flange 55, and adjusting the taper of the taper part 47, the friction force that must be overcome to pivot the display body 10 can be adjusted.

The tilting hinge 60 is provided between the pivoting hinge 40 and the swiveling hinge 80 and enables the display body 10 to tilt relative to the stand 100, that is the display body 10 rotates around a tilting axis 67.

The tilting hinge 60 has the tilting bracket 61 that engages the pivoting support bracket 51, and tiltably engages a tilting support bracket 71, which in turn, engages a swiveling bracket 81 of the swiveling hinge 80.

Both sides of the tilting bracket 61 are bent backward, and it has a cross section in the shape of ‘’. In a center of the tilting bracket 61, there is provided a plurality of sixth screw holes 62 engaged by the third screws 53, and corresponding to the fifth screw holes 52 of the pivoting support bracket 51. In a center of the sixth screw holes 62, the tilting bracket 61 also has a snap ring accommodating part 63 to accommodate the pivoting shaft 45 and the snap ring 49. In end parts of both sides of the tilting bracket 61, there are bolt accommodating parts 64 to allow a screw bolt 77 to be inserted thereinto. In addition, the end parts of the sides of the tilting bracket 61 each have a pair of stoppers 65 with faces forming a predetermined angle, that accommodate a tilting projection 75 (to be described later) of the tilting support bracket 71 to restrict a tilting angle.

Both sides of the tilting support bracket 71 are bent upward, and it has a cross section in the shape of ‘’. In a center of the tilting support bracket, there is provided a plurality of seventh screw holes 72, engaged by fourth screws 76, and corresponding to eighth screw holes 82 of the swiveling bracket 81. In a center of the seventh screw holes 72, the tilting support bracket 71 also has a snap ring accommodating part 63 to accommodate the snap ring 49 engaged with a swiveling shaft 85. In end parts of sides of the tilting support bracket 71, there are bolt accommodating parts 64 formed to allow the screw bolt 77 to be inserted thereinto.

In addition, the end parts of the sides of the tilting support bracket 71 each has a tilting projection 75 accommodated in the stoppers 65 of the tilting bracket 61 to restrict the tilting angle of the tilting bracket 61.

It will be appreciated that the stoppers may be located on the tilting support bracket and the tilting projections may be located on the tilting bracket.

The screw bolt 77 is inserted into the bolt accommodating parts 64 of the tilting bracket 61 and the tilted support bracket 71, and then is engaged by a screw nut 78, to thereby enable the display body 10 to rotate around the screw bolt 77. Also, a friction force resisting tilting can be adjusted by adjusting an engaging force of the screw bolt 77 and the screw nut 78. Further, a range of tilting angle of the display body 10 can be adjusted by adjusting the size of the stoppers 65 and the corresponding tilting projections 75.

The swiveling hinge 80 is provided between the tilting hinge 60 and the stand supporter 103, and allows the display body 10 to swivel relative to the stand 100, that is, the display body 10 rotates around a swiveling axis 86.

The swiveling hinge 80 includes the swiveling bracket 81, that engages the tilting support bracket 71 and swivelably engages a swiveling support bracket 91. The swiveling support bracket 91 also engages an upper part of the stand supporter 103. The swiveling shaft 85 projects from the swiveling support bracket 91 toward the swiveling bracket 81. A swiveling shaft accommodating part 92 is located in the swiveling bracket 81 to allow the swiveling shaft 85 to be inserted into the swiveling bracket 81, and swivel. The snap ring 49 engages an end of the swiveling shaft 85 after the swiveling shaft 85 is inserted into the swiveling shaft accommodating part 92.

The swiveling bracket 81 is approximately cylindrical. The swiveling bracket 81 has the plurality of eighth screw holes 82 that are engaged by the fourth screws 76, and correspond to the seventh screw holes 72 of the tilting support bracket 71.

The swiveling support bracket 91 is approximately cylindrical, and a lower part thereof is engaged with the upper part of the stand supporter 103 by screws or the like.

The swiveling shaft projects from the swiveling support bracket 91 toward the swiveling bracket 81, and has an approximately circular cross section. An end part of the swiveling shaft 85 has a taper part 47 so that the snap ring 49 can push the swiveling bracket 81 engaged with the swiveling shaft 85 toward the swiveling support bracket 91.

A sectional diameter of the taper part 47 is smallest at a location closest to the swiveling support bracket 91, and increases as the distance from the swiveling support bracket 91 increases, so that when the snap ring 49 is pushed onto the taper part 47, the swiveling bracket 81 engages the swiveling bracket 81.

The swiveling bracket 81 swivels relative to the swiveling support bracket 91 centering around the swiveling shaft 45. According to one aspect, the swiveling bracket 81 and the swiveling support bracket 91 are made of brass to generate an appropriate friction force when the swiveling bracket 81 swivels relative to the swiveling support bracket 91. According to another aspect, the swiveling bracket 81 and the swiveling support bracket 91 are made of plastic to generate an appropriate friction force when the swiveling bracket 81 swivels relative to the swiveling support bracket 91. A taper of the taper part 47, to which the snap ring 49 is engaged, can be adjusted to adjust the friction force. That is, as the taper of the taper part 47 is increased, the snap ring 49 pushes the swiveling bracket 81 toward the swiveling support bracket 91 with greater force.

Thus, the display body 10 swivels around the swiveling shaft 85, and by adjusting the taper of the taper part 47, the friction force that must be overcome to swivel the display body 10 can be adjusted.

As shown in FIG. 7, the display body 10 of the display apparatus according to the first embodiment of the present invention, can pivot around the pivoting shaft 45. Also, as shown in FIGS. 8A and 8B, the display body 10 of the display apparatus according to the first embodiment of the present invention, can tilt around the screw bolt 77. Further, as shown in FIGS. 9A and 9B, the display body 10 of the display apparatus according to the first embodiment of the present invention, can swivel around the swiveling shaft 85.

As shown in FIGS. 10 through 12B, the primary differences between the display apparatus according to the first embodiment and the second embodiment of the present invention is a swiveling hinge 80a, provided between the tilting hinge 60a and the stand supporter 103, and a swiveling bracket 81a, provided between the swiveling hinge 80a and the tilting hinge 60a.

The swiveling hinge 80a, is provided between the tilting hinge 60a and the stand supporter 103, and allows the display body 10 to swivel relative to the stand 100, that is, the display body 10 rotates around the swiveling axis 86.

The swiveling hinge 80a includes: a swiveling shaft 85a with an upper part that engages the swiveling bracket 81a by screws; a bearing 84 with an inner side that engages the swiveling shaft 85a, and an outer side that engages a swiveling support bracket 91a (to be described later); the swiveling support bracket 91a with an upper part that engages the outer side of the bearing 84 and a lower part that engages the upper part of the stand supporter 103 by screws or the like; and a friction member 83 with a first side that engages the swiveling bracket 81a and a second side that engages an outer side of the swiveling support bracket 91a.

An upper part of the swiveling bracket 81a extends towards the tilting support bracket 71a and engages a lower part of the tilting support bracket 71, that extends toward the swiveling bracketed 81a, with screws. A lower part of the swiveling bracket 81a extends toward the swiveling hinge 80a and engages the first side of the friction part 83 using screws.

The outer side of the swiveling support bracket 91a has a friction member guide part 93 that engages and guides the friction part 83.

According to one aspect the friction part 83 is made of felt to generate an appropriate friction. According to another aspect, the friction part 83 is made of plastic to generate an appropriate friction.

The swiveling bracket 81a engages the swiveling shaft 85a with screws or the like. The swiveling shaft 81a engages the bearing 84, and thus the swiveling bracket 81a swivels relative to the swiveling support bracket 91a. When the swiveling bracket 81a swivels relative to the swiveling support bracket 91a, a friction force is generated between the friction part 83 and the friction member guide part 93.
