System and Method for Display Stand Height Adjustment

Abstract

Information handling system flat panel displays, such as liquid crystal and plasma displays, are supported on an adjustable stand having a rotation limiter that restricts adjustments of display positions to prevent damage to the display. A display bracket allows rotation of a display between landscape and portrait orientations and a support member allows adjustment of the vertical height of the display bracket relative to a base. The rotation limiter is disposed between the display bracket and support member to restrict rotation of the display bracket from the landscape to the portrait orientation when the support member adjusts the display bracket below a predetermined height at which the display extends beyond the support member. The rotation limiter allows rotation of the display bracket above the predetermined height but restricts height adjustment below the predetermined height unless the display bracket is in the landscape orientation.

1 . An information handling system display stand comprising:
 a base operable to rest on a surface;   a display bracket operable to couple to a display and rotate the display between landscape and portrait orientations;   a support member extending upwards from the base to the display bracket and operable to support the display bracket over the base at first and second adjustable heights, the first height associated with the landscape orientation and the second height associated with the portrait orientation; and   a rotation limiter interfaced with the display bracket and operable to prevent rotation from the landscape orientation to the portrait orientation unless the support member first extends the display bracket completely to the second height.   
   
   
       2 . The information handling system display stand of  claim 1  wherein the rotation limiter is further operable to prevent height adjustment from the second height if the display is in the portrait orientation. 
   
   
       3 . The information handling system display stand of  claim 1  further comprising a flat panel display coupled to the display bracket and operable to present information in a landscape orientation or a portrait orientation. 
   
   
       4 . The information handling system display stand of  claim 3  wherein the flat panel display is a liquid crystal display. 
   
   
       5 - 7 . (canceled) 
   
   
       8 . A method for supporting a display in landscape and portrait orientations, the method comprising:
 allowing vertical adjustment of the display with the landscape orientation; and   preventing vertical adjustment of the display below a predetermined height with the portrait orientation until the display is rotated completely to the landscape orientation.   
   
   
       9 . The method of  claim 8  further comprising:
 preventing rotation between the landscape and portrait orientations below the predetermined height.   
   
   
       10 . The method of  claim 9  wherein the display comprises a flat panel display. 
   
   
       11 . The method of  claim 10  wherein the flat panel display is a liquid crystal display. 
   
   
       12 . The method of  claim 10  wherein the flat panel display is a plasma display. 
   
   
       13 - 15 . (canceled) 
   
   
       16 . A system for adjusting the orientation of a flat panel display, the system comprising:
 a display bracket operable to couple to the flat panel display and to rotate the flat panel display between a landscape orientation and a portrait orientation;   a support member operable to adjust the vertical height of the display bracket; and   a rotation limiter interfaced with the display bracket and the support member, the rotation limiter operable to prevent the support member from lowering the vertical height of the display bracket when the display bracket is in the portrait orientation unless the display bracket is first rotated completely to the landscape orientation.   
   
   
       17 . The system of  claim 16  wherein the rotation limiter is further operable to prevent the display bracket from rotating when the support member is below a predetermined height. 
   
   
       18 . The system of  claim 17  wherein the predetermined height comprises the height at which a display coupled to the display bracket will extend beyond the support member during rotation. 
   
   
       19 . (canceled) 
   
   
       20 . The system of  claim 16  wherein the flat panel display comprises a liquid crystal display.
