Electric-elevating desktop

Abstract

An executive/clerical type office desk embodying a fully contained electromechanical system for elevating and lowering the desktop, between a user's seating position and a full standing position. Three telescoping stanchions support and control the desktop height from a standard-desk height to an upper height of about 44 inches. The desktop rest directly on three poles sliding inside the telescoping support stanchions. The sliding poles are lifted and lowered by cables looped-under pulleys mounted in bottom of said poles, and are drawn up and released by an electric-motor-driven cable winch. Anti-friction treatments are in place between the inner sliding members and the supporting stanchions. By said cables looping under pulleys, installed in the bottom of each inner telescoping member, and anchoring atop the telescoping stanchions a lifting mechanical advantage of two is obtained. The user operates a three position electrical switch to raise and lower the desktop. An onboard rechargeable-electrical battery powers the electric motor.

1 . An Electric-Elevating Desktop comprising of:
 a) a desktop composed of rigid, self-supporting materials, that spans an area about that of a convention desktop working areas.   b) a desktop-elevating mechanism embodying a cable-winch drawn by a high-ratio gear assembly driven by an electric motor.   c) a fabricated metal, plastic, or wood structure for supporting the desktop, elevating mechanism, and electrical system(s).   d) an electrical system, located under said desktop, for powering said elevating mechanism, and consisting of: electrical motor, re-chargeable battery, and a user's three-position control switch.   c) an optional DC to AC inverter located under said desktop for powering such as: computers, clock radios, electrical razors, etc.   
     
     
         2 . Said desk improves user's job efficiency and provides relief from: mental and physical fatigue, physical impairment, and lethargy, by rising users from a seated position to full standing—without interrupting ongoing business responsibilities. Spacious under-clearance of said desktop facilitates a variety of drawers, and enables conferencing of up to six attendees. 
     
     
         3 . An optional onboard DC to AC inverter supplies power for electrical devices, such as: computers, clock radios, electrical razors, etc. 
     
     
         4 . Said desk's three-point suspension and method of desktop attachment enables a variety of desktop compositions and colors. Its weight, from being self-supporting, along with the weight of the elevating mechanism, and the stanchion's anti-friction treatment, insures reliable gravity force lowering of the desktop when the cable winch is operated in the reverse direction. The gear assemble driving the cable winch, being of high-ratio, eliminates the need for electrical or mechanical braking. And a motor-to-gear-box clutch negates the need for circuits to stop motor drive at upper and lower ends. 
     
     
         5 . Support structure of said desk, being artistically designed and finished in appealing colors, makes its presence and decore respectable in most offices and executive suites.
