Structure for an adjustable height work surfaces cooperating with linear extension mechanisms

Abstract

A structural configuration of a under frame cooperating with linear extension mechanisms supports an adjustable height work surface with diagonal structural elements oriented and located to extend stability from the base objects to the WS directly, or proximate to an under frame location cooperating with the WS and further comprising under frame lateral structural elements that communicates a substantial fraction of both downward loads and horizontal torsional forces to the lower extents of the vertical structural elements resulting in improved stability of the vertically extended work surface.

What is claimed is: 
     
         1 ) An under frame structure of a work surface cooperating with linear extension mechanisms and position retention devices that in further cooperation with base structures, communicates stability therefrom to the underframe in height adjustable positions, the underframe structure comprising:
 a) vertical elements connected to the work surface;   b) diagonal elements oriented and positioned proximate to said stability and operably linked thereto, extending therefrom to further operably communicate said stability to the work surface in height adjustable positions;   c) work surface embodied lateral elements operably linked to said underframe structure where the larger fraction of off-center downward loads and torsional forces are communicated downward through the diagonal elements, the lateral elements communicating the minor fraction thereof to the upper extents of the vertical elements, thereby providing improving the stability of the work surface.   
     
     
         2 ) The under frame structure of  claim 1  where a spreading apart of the vertical elements and the coupling element into separate elements provides a fixed top symmetric structure for free standing structures wherein:
 a) a second diagonal element extends from each vertical element symmetrically, 
 b) the tops of the diagonal objects and the vertical objects further connected to the work surface, 
 c) the embodied structural elements in the work surface complete this structure, enabling improved WS stability. 
 
     
     
         3 ) The under frame structure of  claim 2  where a vertical elements and cooperating diagonal elements are comprised of one or more objects. 
     
     
         4 ) The under frame structure of  claim 1  where an inward angular orientation of the diagonal elements preferably aligned with torsional forces improves resistance to these forces wherein:
 a) a preferred orientation for torsional resistance locates both connected ends of the diagonal elements proximate to the same radius from the axis of said torsional forces. 
 
     
     
         5 ) The underframe of  claim 1  further comprising added structural objects to cooperate with a chosen method of lift assistance wherein:
 a) some methods of lift assistance also operably provide position retention, where these and other methods can provide the function of the position retention herein. 
 
     
     
         6 ) The under frame structure of  claim 1  wherein said diagonal elements are further inclined inward and cooperate with a coupling object further connected to lateral elements that connect to the vertical elements, wherein:
 a) the work surface comprises an articulating device connected to the coupling element exclusively supporting the WS, enabling tilting or other articulation of the work surface, the under frame thereby providing the same improved stability and further enabling an articulating work surface. 
 
     
     
         7 ) The under frame structure of  claim 6  where the connections of elements may be fixed, or pivotable, or embodied in objects to achieve various functionality and product objectives. 
     
     
         8 ) The under frame structure of  claim 6  where lateral elements may be:
 a) embodied in the work surface 
 b) rigidly or pivotably cooperating with connected elements, 
 c) inclined in non-horizontal sloping orientations, 
 d) comprised of one or more locking objects that cooperate with a device or method for unlocking the objects, 
 e) embodied together in one or more objects, 
 f) embodied in object pairs with a diagonal elements described as sides, 
 
     
     
         9 ) The under frame structure of  claim 6  comprised of one or more objects that adequately retain the dimensions between the connections of the structural elements when subjected to anticipated downward loads and torsional forces, are not otherwise limited in shape or appearance. 
     
     
         10 ) The under frame structure of  claim 10  provides the added function of a shelf below the work surface ideal for locating interconnections of electrical accessories. 
     
     
         11 ) The under frame structure of  claim 6  comprised of one or more objects that may be molded, cast, or formed that cooperates with slides, a panel object, and the work surface, and further providing a multi-surface exterior thereby facilitating decorative opportunities for targeting markets, and where fewer parts is a cost advantage. 
     
     
         12 ) The underframe of  claim 6  may further comprise added structural objects to cooperate with a chosen method of lift assistance wherein:
 a) some lift assistance methods also function as position retention mechanisms 
 b) alternative methods of position retention as well as lift assistance are matters of choice.
