     DETAILED DESCRIPTION 
       FIGS.  1 A- 1 C  illustrate a telescoping monitor mount  100 . Telescoping monitor mount  100  includes two telescoping arms  120  extending on either side of a center post  140  with two monitor mounting brackets  110  mounted to the ends of the two telescoping arms  120 . Specifically,  FIG.  1 A  illustrates a perspective view of telescoping monitor mount  100  with telescoping arms  120  in collapsed positions, whereas  FIG.  1 B  illustrates a perspective view of telescoping monitor mount  100  with telescoping arms  120  in extended positions.  FIG.  1 C  illustrates a close-up view of a portion of a telescoping arm  120  showing an outer tube  122 , an inner tube  124  slidable within the outer tube  122  and two set screws  126 . 
     In the example of telescoping monitor mount  100 , center post  140  is a straight tubular post with a round cross-section. In various examples, center post  140  may be 300 to 900 millimeters (mm), such as about 430 mm long. In the same or different examples, center post  140  may be formed from a thin-walled metal tube, such as a steel or aluminum tube. In other examples, center post  140  may be a rectangular tubular post, or non-tubular post, such as a u-channel post or extruded metal post. 
     Slidable bracket  130  fits over center post  140  and facilitates a selectable height for telescoping arms  120 . In this manner, center post  140  represents a common stand for both telescoping arms  120 . In the example of telescoping monitor mount  100 , slidable bracket  130  includes a circumferential clamp mechanism for fixation to center post  140 . In other examples, slidable bracket  130  may include a setscrew or other adjustable fixation mechanism. 
     Two telescoping arms  120  are pivotably connected to slidable bracket  130  by two pivot points  132 . In the example of telescoping monitor mount  100 , pivot points  132  each include pivot pin extending through holes in slidable bracket  130  and the corresponding telescoping arm  120 . In other examples, pivot points  132  may include a hinge, a four-bar linkage, or other pivot mechanism. 
     Each telescoping arm  120  includes an outer tube  122 , an inner tube  124  slidable within the outer tube  122 , and two set screws  126  extending through a threaded hold in the outer tube  122 . Set screws  126  selectively contact the inner tube  124  to fix the extension of the inner tube  124  relative to the outer tube  122 . 
     The total length of telescoping arms  120  is selected according to the maximum size desired for mounting monitors. For example, for monitors up to 32 inches, each of telescoping arms  120  may have a maximum extended length of at least 800 mm, which would provide a minimum length of about 420 mm, with a range of adjustment of about 380 mm. In one particular example, each of telescoping arms  120  has a maximum extended length of 832 mm with a minimum length of 437 mm, which would be suitable for displays ranging from 19 inches to 34 inches. In various examples, telescoping arms  120  may facilitate a range of adjustment between 200 mm and 500 mm. 
     The construction of outer tube  122  and inner tube  124  is selected to support the weight of mounted monitors as well as provide limited bending of telescoping arms  120  at the maximum extended length of telescoping arms  120 . The outer diameter of inner tube  124  is selected to be slightly smaller than the inner diameter of outer tube  122 . For example, the outer diameter of inner tube  124  may be within 1 mm, such as within 0.5 mm of the inner diameter of outer tube  122 . In various examples, outer tube  122  may have tube size of 25 mm by 15 mm by 1.5 mm to 51 mm by 25 mm by 2.5 mm, such as a tube size of 30 mm by 20 mm by 2 mm. In the same examples, inner tube  124  may have tube size of 20 mm by 10 mm by 1.5 mm to 45 mm by 19 mm by 2.5 mm, such as a tube size of 25.5 mm by 15.5 mm by 2 mm. In yet further examples, telescoping arms  120  may be formed from nesting bars, such as bars with u-shaped channels rather than outer tube  122  and inner tube  124 . 
     Telescoping monitor mount  100  further includes two monitor mounting brackets  110  connected to ends of the two telescoping arms  120  opposite the slidable bracket  130  by pivots  112  on the end of inner tubes  124 . In some examples, the mounting holes of monitor mounting brackets  110  may conform to a VESA standard display mount. Such VESA standard display mounts include rectangular hole patterns such as 50×20 mm, 75×35 mm, 75×75 mm, 100×100 mm, 200×100 mm, 400×200 mm, 600×400 mm, and others in 200 mm increments. 
     Telescoping monitor mount  100  includes a clamp  150  connected to the center post  140  for securing the center post  140  to a desktop or other worksurface (not shown) in an upright orientation. Slidable bracket  130  may be selectively positioned on center post  140  to select a height of monitor mounting brackets  110  relative to clamp  150  and the desktop. 
     Clamp  150  includes an L-bracket  152  attached to the end of center post  140 . L-bracket  152  is configured to register with the top side of a worksurface. Clamp  150  further includes L-bracket  153 , which is attached to L-bracket  152  to form a C-shaped bracket. L-bracket  153  may be attached with rivets, bolts, or other techniques. In other examples, L-brackets  152 ,  153  may be a unitary component. Clamp member  154  is configured to register with the bottom side of the worksurface. Clamp member  154  includes a threaded shaft  156  that extends through a threaded hole in L-bracket  153 . Handle  155  is at the end of threaded shaft  156  and allows a user to adjust the spacing of clamp member  154  relative to L-bracket  152  in order to secure clamp  150  to the worksurface. 
     While telescoping monitor mount  100  includes clamp  150  for connection to a worksurface, other mounting techniques are also possible. For example, center post  140  may include a base sized to fit with in a hole in a worksurface, such as a standard 2-inch cable hole. 
     As another example, center post  140  may include a ceiling mount to facilitate hanging from a ceiling instead of clamp  150 . In such examples, it is important for such a ceiling mount to provide sufficient attachment strength to a ceiling to hold the weight of telescoping monitor mount  100  and displays mounted thereon. Such a ceiling mount may include a plate with holes. The plate may be configured for attachment to a standard ceiling fan fixture box or sized to facilitate attachment to structural framing members. In various examples, the holes may be spaced at least 16 inches or at least 24 inches to facilitate direct attachment to structural framing elements behind a finished ceiling surface. 
       FIGS.  2 A- 2 C  illustrate a telescoping monitor mount  200 . Telescoping monitor mount  200  includes two curved telescoping arms  220  extending on either side of a center post  240  with two monitor mounting brackets  210  mounted to the ends of the two telescoping arms  220 . Specifically,  FIG.  2 A  illustrates a perspective view of telescoping monitor mount  200  with telescoping arms  220  in extended positions.  FIG.  2 B  illustrates a top view of telescoping monitor mount  200  with telescoping arms  220  in extended positions, and  FIG.  2 C  illustrates a top view of telescoping monitor mount  200  with telescoping arms  220  in collapsed positions. As shown in  FIG.  3   , the curve of the telescoping arm  220  facilitate increase viewing angle adjustability for monitors  240 A,  240 B without interference from telescoping arm  220 . 
     Telescoping monitor mount  200  is substantially similar to telescoping monitor mount  100  except that telescoping arms  220  are curved rather than straight. In addition, telescoping monitor mount  200  includes a third monitor mounting bracketing bracket  210  pivotably connected to the center post such  240  that the third monitor mounting bracketing bracket  210  is between the monitor mounts on the ends of telescoping arms  220 . 
     Telescoping monitor mount  200  includes a center post  240  and a slidable bracket  230  over the center post. Two telescoping arms  220  are pivotably connected to slidable bracket  230  by two pivots  232 . Each telescoping arm  220  includes an outer tube  222 , an inner tube  224  slidable within the outer tube  222  and two set screws  226  extending through a threaded hold in the outer tube  222 . Set screws  226  selectively contact the inner tube  224  to fix the extension of the inner tube  224  relative to the outer tube  222 . 
     Telescoping monitor mount  200  further includes two monitor mounting brackets  210  connected to ends of the two telescoping arms  220  opposite the slidable bracket  230  by pivots  212  on the end of inner tubes  224 . In some examples, the mounting holes of monitor mounting brackets  210  may conform to a VESA standard display mount. Such VESA standard display mounts include rectangular hole patterns such as 50×20 mm, 75×35 mm, 75×75 mm, 200×200 mm, 200×200 mm, 400×200 mm, 600×400 mm and others in 200 mm increments. 
     Telescoping monitor mount  200  includes a clamp  250  connected to the center post  240  for securing the center post  240  to a desktop (not shown) in an upright orientation. Slidable bracket  230  may be selectively positioned on center post  240  to select a height of monitor mounting brackets  210  relative to clamp  250  and the desktop. 
     The two telescoping arms  220  are curved in the same plane and direction. Outer tubes  222  and inner tubes  224  form coincident circular curves such that inner tubes  224  are slidable within the respective outer tubes  222  along the coincident circular curve. 
     As shown in  FIG.  3   , the curvature of telescoping arms  220  is selected to provide clearance for monitors mounted to mounting brackets  210 . In some examples, the curvature of curvature of telescoping arms  220  may have a center line radius (CLR) of between 850 mm to 1000 mm, such as about 900 mm CLR. Any suitable manufacturing techniques may be used to form the curvature of outer tubes  222  and inner tubes  224 . For example, a tube bender or a press may be used to bend a straight tube to the proper curvature, optionally with a bending gauge. As another example, outer tubes  222  and inner tubes  224  may be metal castings formed with the desired curvature. 
       FIG.  3    illustrates a portion of an assembly  300  including telescoping monitor mount  200  and three monitors mounted to monitor mounting brackets  210 , although only two monitors  240 A,  240 B are visible. As shown in  FIG.  3   , the curves of outer tubes  222  and inner tubes  224  combine to facilitate increase viewing angle adjustability for monitors  240 A,  240 B without interference from telescoping arm  220 . In contrast, a straight telescoping arm  220 X with a straight outer tuber  222 X and a straight inner tube  224 X would not allow monitors  240 A,  240 B to be angled as shown. 
     The specific techniques for telescoping monitor mounts, including techniques described with respect to monitor mounts  100 ,  200 , are merely illustrative of the general inventive concepts included in this disclosure as defined by the following claims.
