Dynamic standing desk

Abstract

A dynamic standing desk having a work surface configured to move with planar motion parallel with the ground and with a range of movement that adjusts as a function of the size of a user of the desk. The desk may include a base, a tabletop that includes the work surface, a frame that movably couples the tabletop to the base, and at least one actuator configured to provide the planar motion. The desk may be used to reduce lower musculoskeletal discomfort of a user of the desk by oscillating the work surface of the desk with a range of movement based on a length of a limb of the user.

         26 . The dynamic standing desk of  claim 21 , wherein the planar motion is at a rate between 2 millimeters per second and 10 millimeters per second. 
     
     
         27 . The dynamic standing desk of  claim 21 , further comprising:
 a base;   a tabletop that includes the work surface;   a frame that movably couples the tabletop to the base; and   at least one actuator configured to provide the planar motion.   
     
     
         28 . The dynamic standing desk of  claim 27 , wherein the at least one actuator includes a first actuator configured to move the tabletop with respect to the frame along a first direction and a second actuator configured to move the frame with respect to the base along a different second direction, the frame being stationary with respect to the tabletop in the second direction. 
     
     
         29 . The dynamic standing desk of  claim 21 , further comprising a tabletop that includes the work surface, wherein the tabletop includes a cut-out at which the user stands. 
     
     
         30 . The dynamic standing desk of  claim 21 , further comprising a controller configured to receive information pertinent to the size of the user and to set the range of movement based on the received information. 
     
     
         31 . The dynamic standing desk of  claim 21 , further comprising a sensor configured to differentiate the user from a different user, the desk being further configured to adjust the range of movement based on information from the sensor. 
     
     
         32 . A dynamic standing desk, comprising:
 a work surface configured to automatically move with respect to a user standing at the desk to use the work surface; and   a cueing system configured to provide tactile cues to the user during movement of the work surface with respect to the user.   
     
     
         33 . The dynamic standing desk of  claim 32 , wherein the cueing system comprises a physical cueing device having laterally spaced portions extending posteriorly with respect to the user and along opposite left and right sides of the user when the user stands between said laterally spaced portions to use the work surface. 
     
     
         34 . The dynamic standing desk of  claim 32 , further comprising a tabletop that includes the work surface, wherein the cueing system comprises a cut-out and edges of the cut-out provide the tactile cues to the user when the user stands in the cut-out during movement of the work surface with respect to the user. 
     
     
         35 . The dynamic standing desk of  claim 32 , further comprising a tabletop that includes the work surface, wherein the cueing system comprises extensions extending away from the tabletop such that the user is at least partially surrounded by the desk when standing at the desk to use the work surface, with an edge of the tabletop in front of the user and extensions on opposite left and right sides of the user. 
     
     
         36 . The dynamic standing desk of  claim 32 , wherein the work surface is configured to move with bidirectional linear motion only. 
     
     
         37 . A dynamic standing desk comprising a work surface configured to automatically move parallel with the ground with only bidirectional linear motion, wherein the motion is mediolateral with respect to a user standing at the desk and facing the work surface to use the work surface. 
     
     
         38 . The dynamic standing desk of  claim 37 , further comprising:
 a base;   a tabletop that includes the work surface; and   an actuator configured to provide the bidirectional linear motion with respect to the base, wherein the actuator is the only actuator configured to move the tabletop parallel with the ground.   
     
     
         39 . The dynamic standing desk of  claim 37 , wherein the work surface moves at a rate between 2 millimeters per second and 10 millimeters per second with respect to the ground. 
     
     
         40 .
