Portable and adjustable desktop workstation

Abstract

According to principles of the present inventive concepts, a desktop workstation in configured to be supported on an existing work surface and enable adjustment of a height of a work surface between a lowered and a raised position. In a lowered position, the work surface is arranged at a height from the existing work surface that facilitates use by a user in a seated position and, in a raised position, the work surface is arranged at a height from the existing work surface that facilitates use by the user in a standing position.

What is claimed is: 
     
         1 . A workstation configured to rest on an existing work surface and permit adjustment of a height of a work surface relative to the existing work surface, said work station comprising:
 a work surface comprising one or more work platforms;   a leg assembly configured to stably support the one or more work platforms at any of multiple user selectable height positions with respect to the existing work surface; and   an adjustment mechanism that permits a user to selectively adjust the height of the work surface between the multiple user selectable height positions.   
     
     
         2 . A workstation according to  claim 1 , wherein the one or more work platforms comprise a main work platform and a secondary work platform arranged at different heights with respect to each other and the existing work surface. 
     
     
         3 . A workstation according to  claim 2 , wherein the main work platform is configured to support one or more monitors and wherein the secondary work platform is configured to support a keyboard and a tracking device. 
     
     
         4 . A workstation according to  claim 1 , wherein the one or more work platforms comprises a single platform configured to support one or more monitors and a keyboard. 
     
     
         5 . A workstation according to  claim 1 , wherein the leg assembly comprises a first leg assembly and a second leg assembly connected together in a scissored relationship. 
     
     
         6 . A workstation according to  claim 1 , wherein the first leg assembly is connected to the one or more work platforms in a fixed hinged relationship, and wherein the second leg assembly is connected to the one or more work platforms in a sliding hinged relationship. 
     
     
         7 . A workstation according to  claim 6 , wherein the sliding hinged relationship is provided using a sliding rail connected to the second leg assembly through one or more hinges, and wherein the sliding rail is connected to a track assembly attached to the one or more work platforms. 
     
     
         8 . A workstation according to  claim 1 , wherein the multiple user selectable height positions includes a lowered position to facilitate use of the workstation by a user in a sitting position and a raised position to facilitate use by a user in a standing position. 
     
     
         9 . A workstation according to  claim 8 , further comprising a biasing mechanism configured to bias the workstation in the raised position. 
     
     
         10 . A workstation according to  claim 7 , further comprising a control rod connected to the sliding rail and configured to frictionally engage a release lever, such that said control rod holds the workstation in a desired position until the release lever is actuated. 
     
     
         11 . An adjustable workstation configured to be supported on an existing work surface, said workstation comprising:
 a work platform configured to be adjustable between a raised position to facilitate use by a user in a standing position, and a lowered position to facilitate use by a user in a sitting position; and   an adjustment mechanism that permits the user to adjust the height of the work platform between the raised and lowered positions.   
     
     
         12 . A workstation according to  claim 12 , further comprising a leg assembly arranged to support the work platform in either the raised or lowered position depending on the user selection. 
     
     
         13 . A workstation according to  claim 12 , wherein the leg assembly comprises first and second leg assemblies connected together in a scissored relationship. 
     
     
         14 . A workstation according to  claim 13 , further comprising a sliding rail connected to the work platform in a sliding relationship, wherein the first leg assembly is connected to the sliding rail to adjust a location of an upper end of the first leg assembly with respect to the work platform. 
     
     
         15 . A workstation according to  claim 14 , further comprising a biasing mechanism configured to bias the sliding rail in toward a center of the work platform. 
     
     
         16 . A workstation configured to rest on an existing work surface and permit adjustment of a height of a work platform relative to the existing work surface, said work station comprising:
 one or more work platforms;   a leg assembly comprising first and second leg assemblies connected together in a scissored relationship, said leg assembly configured to stably support the one or more work platforms at any one of multiple user selectable height positions with respect to the existing work surface;   a track assembly arranged on the one or more work platforms, wherein an upper end of the second leg assembly is connected to one or more work platforms in a slidable relationship through the track assembly; and   an adjustment mechanism that permits a user to selectively adjust the height of the work surface between the multiple user selectable height positions.   
     
     
         17 . A workstation according to  claim 16 , further comprising a slide rail connected to the track assembly to slide between a position near a side of the work platform and a center of the work platform, wherein the slide rail is further connected to the upper end of the second leg assembly in a hinged relationship. 
     
     
         18 . A workstation according to  claim 17 , wherein the first leg assembly is connected to the work platform in a hinged relationship at a fixed position. 
     
     
         19 . A workstation according to  claim 18 , further comprising a biasing spring attached between the slide rail and a location on the work platform, wherein the biasing spring biases a position of the slide rail toward the center of the workstation. 
     
     
         20 . A workstation according to  claim 19 , further comprising a control rod connected to the slide rail and disposed through a release lever arranged at a side of the workstation, wherein the release lever is configured to engage the control rod in a frictional relationship to maintain the workstation in its raised position until the release lever is depressed.
