Abstract:
A stand, rotatable through approximately 180 degrees, supports a display device in such a way that whilst the height of the display device above a supporting surface is variable, a full range of viewing angles is also available at any height.

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a display device, more particularly to a display device with a rotatable stand. 
     2. Description of Related Art 
     A stand is usually provided to support a monitor. In order to adjust a visual angle of the monitor, the stand should be designed to be rotatable relative to the monitor. However, the height of the monitor cannot generally be adjusted. Therefore, there is room for improvement in the art.

     DETAILED DESCRIPTION 
     The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.” 
       FIG. 1  illustrates a display device of an embodiment. The display device comprises a monitor  10  and a stand  20 . 
     The monitor  10  comprises a first cover  12 , a screen  13  (shown in  FIG. 2 ), and a second cover  11 . The second cover  11  is secured to the first cover  12 , and the screen  13  is secured to the first cover  12 . The first cover  12  comprises a cover plate  121  and a convex part  123  protruding from the cover plate  121 . A concave portion  1231  (shown in  FIG. 3 ) is defined in the convex part  123  of the first cover  12 . A through opening  124  is defined in the concave portion  1231 . Referring to  FIGS. 3 and 4 , an anti-slip pad  1213  is attached to both sides of the bottom edge of the monitor  10 . 
     The stand  20  is an item of unitary construction, but reference will be made hereafter to two different portions, namely a first pole  21  and a second pole  22 . An acute angle is defined between the first pole  21  and the second pole  22 . The first pole  21  defines two cutouts  2111  at opposite sides of a distal end of the first pole  21 , and two first fixing holes (not labeled) are defined in the distal end. The second pole  22  comprises a pivot portion  221  at the distal end. The pivot portion  221  defines a through hole  2211 . Referring to  FIGS. 3 and 4 , an anti-slip pad  223  is attached to a bottom of the second pole  22 . 
     The display device further comprises a support  50  attached to the second pole  22 , to provide stability to the stand  20 . The support  50  comprises a first supporting portion  52  and a second supporting portion  51 . The first supporting portion  52  comprises a pivot pole  521 . The second supporting portion  51  defines a pivot hole  511 . A cylindrical anti-slip ring  53  is adjacent to the respective distal ends of each of the first supporting portion  52  and the second supporting portion  51 . A cross-section of each of the first supporting portion  52  and the second supporting portion  51  is circuit, and the cross-section is substantially perpendicular to a central axis of the support  50 . A cross-section of the support  50  is circular, and the cross-section is substantially perpendicular to a central axis of the support  50 . 
     The display device further comprises a mounting member  30  configured to be secured to the first cover  12 . The mounting member  30  comprises two mounting pieces  31  and a rotating piece  32 . The rotating piece  32  is rotatably secured between the two mounting pieces  31  by two pivots  33 . The rotating piece  32  defines two second fixing holes. 
     Referring to  FIGS. 1 and 3 , in assembly, the two mounting pieces  31  of the mounting member  30  are fixed to an inner surface of the first cover  12 . The rotating piece  32  is inserted through the first cover  12  from inner side to outer side via the through opening  124 . The second cover  11  is secured to the first cover  12  and secures the screen  13  to the first cover  12 . The distal end of the first pole  21  is engaged in the concave portion  1231 . The two pivots  33  of the mounting member  30  are received in the two cutouts  2111  of the first pole  21 . The two first fixing holes of the first pole  21  are aligned with the two second fixing holes of the rotating piece  32 , and two fasteners (not shown), such as screws, are fixed in the two first fixing holes and the two second fixing holes to secure the distal end of the first pole  21  to the rotating piece  32 . Thus, the first pole  21  can be rotated together with the rotating piece  32  relative to the first cover  12 . 
     The pivot pole  521  of the first supporting portion  52  slides through the through hole  2211  of the second pole  22  and is forced with slight effort into the pivot hole  511  of the second supporting portion  51 , and the support  50  is thus rotatably secured to the second pole  22 . In an embodiment, the support  50  is substantially perpendicular to at least one of the first pole  21  and the second pole  22 . 
     In use, the stand  20  is rotatable between a first position (illustrated in  FIGS. 2 and 3 ) and a second position (illustrated  FIGS. 4 and 5 ), through approximately 180 degrees relative to the monitor  10 . When the stand  20  is in the first position, the second pole  22  and the support  50  are both flat on a supporting surface to supporting the monitor  10  at a first viewing angle. The supporting surface may be a top surface of a desk or a floor, for example. The anti-slip rings  53  and the anti-slip pad  223  stick to the supporting surface with substantial friction between the support surface and bottoms of the second pole  22  and the support  50 . When the first viewing angle needs to be adjusted, the monitor  10  is rotated relative to the stand  20 . In the rotation of the monitor  10 , the two mounting pieces  31  rotate with the monitor  10  relative to the rotating piece  32 . When the stand  20  is rotated from the first position to the second position, the first pole  21  is sunk into and lies in the concave portion  1231  and abuts a rear side of the monitor  10 . The second pole  22 , the support  50  and a bottom of the monitor  10  stand on the supporting surface and support the monitor  10  at a second angle. The anti-slip pads  1213  of the monitor  10  and the second anti-slip pad  223  grip the supporting surface with substantial friction between the supporting surface and a bottom of each of the monitor  10  and the stand  20 . In the rotation of the stand  20 , the rotating piece  32  is rotated together with the first pole  21  relative to the monitor  10  and the two mounting pieces  31 . The height of the display device in the first position is thus greater than that in the second position. 
     In an embodiment, the second pole  22  is substantially perpendicular to the screen  13  when the monitor  10  is in the first position, and the first pole  21  is substantially parallel to the screen  13  when the monitor  10  is in the second position. 
     It is to be understood however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
