Height-adjustable multi-function desk

Abstract

A workstation system ( 1 ) has an office desk with a seated work area and a standing working area. A support frame ( 10 ) is height-adjustable in the vertical axis H for synchronously adjusting the height of two desktops (T 1, T 2 ) attached to the frame at different work levels (A 1, A 2 ) to form respective seated and standing working areas. The desktops (T 1, T 2 ) are attached to the support frame at a fixed distance to each other in the vertical axis H. The upper desktop (T 2 ) is arranged above the working level (A 1 ) of the lower desktop (T 1 ) in the vertical axis.

         13 . A workstation system comprising:
 an office desk having a seated work area and a standing working area;   a support frame height-adjustable along the vertical axis synchronously adjusting height of two desktops attached to the frame at different work levels for forming respective seated and standing working areas;   the desktops are attached to the support frame at a fixed distance to each other on the vertical axis and the upper desktop is arranged above the working level of the lower desktop along the vertical axis.   
     
     
         14 . The workstation system according to  claim 13 , wherein the upper and lower desktops are formed from a single piece and/or a single component. 
     
     
         15 . The workstation system according to  claim 13 , wherein the distance of a top from the lower desktop to a bottom of the upper desktop lies in the range between 27-39 cm preferably in the range between 31-36 cm, further preferably is 33 cm. 
     
     
         16 . The workstation system according to  claim 13 , wherein the lower and upper desktops are connected to each other via a vertical desk section. 
     
     
         17 . The workstation system according to  claim 13 , wherein the upper desktop has a width that corresponds to about 30-60%, preferably 50%, of a width of the lower desktop. 
     
     
         18 . The workstation system according to  claim 13 , wherein a work surface of the upper desktop is positioned directly above the lower desktop in a perpendicular projection onto the lower desktop, such that the remaining working area of the lower desktop, above which no section of the upper desktop is located, is freely accessible from above and defines the seated work area. 
     
     
         19 . The workstation system according to  claim 13 , wherein a control device detects whether an identified user is in the seated or standing position at the desk, and the control device, depending on personal data stored for that user, in particular with regard to one or more body dimensions, performs an automatic height adjustment in a range of −7 cm to +7 cm, preferably −3 to +3 cm, to accommodate a seated or standing position. 
     
     
         20 . The workstation system according to  claim 13 , wherein orientation of a front edge of the upper desktop that is directed toward a user, is at an angle of about 30° to an orientation of a front edge of the lower desktop. 
     
     
         21 . The workstation according to  claim 13 , wherein a vertical support strut extends between the lower desktop and the upper desktop. 
     
     
         22 . The workstation system according to  claim 13 , wherein a height adjustment device is provided with a travel of no more than 14 cm. 
     
     
         23 . The workstation system according to  claim 13 , wherein the lower and upper desktops are connected to each other via a joint, such that the upper desktop can be rotated relative to the lower desktop about a rotary axis while maintaining the working levels. 
     
     
         24 . A method for setting up and adjusting the height of a desktop of a workstation system according to  claim 13 , that is equipped with a control system for the automatic or user-activated synchronous adjustment of the height of the desktops of the workstation, when switching from a seated to a standing position, and/or vice versa, for an individual user comprising the steps of:
 Entering user-specific physical data, such as height, leg length or torso length of a user;   Setting a first height position of the lower desktop for the user, that corresponds to a desired height for working in the seated position;   Determining whether the height of the upper desktop at the height position of the lower desktop matches the corresponding body measurements for a reference user stored in the system and, if a deviation is detected, store a height correction value in the range between +/−7 cm, such that, in case of an actual or detected change of this user from the seated position to the standing position, the controller performs, either automatically or user-prompted, a height adjustment according to the height correction value, and a corresponding correction is performed in the opposite direction when the user returns from the standing position to a seated position.
