Few workstations are available with powered monitor “lifts” they usually have a second pedestal driven surface. I have no knowledge of any prior “monitor lift” that raises the monitor with and above the main work surface that does not occupy a considerable portion of the main work surface.

Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 10/272,730 filed Oct. 15, 2002, which claims priority of U.S. Provisional Patent Application Ser. No. 60/330,331 filed Oct. 19, 2001.
- U.S. Department of Education SBIR grant #ED-99-PO-4679, “Development of an ergonomic computer workstation environment” funded research in local schools on the need for adjustable ergonomic computer workstation environments. We found over 90% of students in any given age group or grade did not fit the computer workstations available in their school. It was demonstrated that the MOTORIZED ADJUSTABLE WORKSTATION invention, with a motor driven work surface and a motor driven monitor lift, had enough range of movement to ergonomically adjust to accommodate 6-year-old first graders to 6′3″ high school students.
- This invention relates to the field of adjustable workstations. The preferred embodiment of the invention is a computer workstation. The use of adjustable workstations may reduce repetitive stress injuries of users. User types include but are not limited to: workers, students, families and individuals. The advantage of adjustable height work surface(s) is the ergonomic positioning of work materials and various equipment in the field of labor, education and especially computer use, etc. More specifically, this invention relates to a new, sturdy, affordable, adjustable, powered, ergonomic workstation solution that can be used to substantially improve user access to ergonomically adjustable workstations.
- Health professionals, OSHA and other federal and state agencies recognize the value of adjustable workstations and the benefits of adjustable work surface heights are well established. Dr. Alan Hedges of Cornell University and others have recognized that these same problems and solutions apply to K-12 grade school children; ergonomically, adjustable workstation solutions appropriately sized for students would improve postures at computer terminals in schools.
- The disadvantage of prior inventions are: the majority of “adjustable” workstations are “maintenance adjustable” requiring a mechanical takedown of the workstation to change heights, the next class of “adjustable” workstations are hand-cranked, gear driven workstations that can require up to 13 turns or more per inch of vertical travel, an obvious disadvantage for those with, or prone to, wrist, hand, arm or upper body repetitive stress injuries; these types of “adjustable” workstations are not likely to be utilized. Few workstations are available with powered monitor “lifts” they usually have a second pedestal driven surface. I have no knowledge of any prior “monitor lift” that raises the monitor with and above the main work surface that does not occupy a considerable portion of the main work surface.
- Adjustable height electrical pedestal style tables have large pedestals raising centrally from a cross member at or near floor level, the pedestal is large enough to contain the electric drive, provide a wide bearing surface that controls lateral table movement and big enough to sustain the bending moment occurring at the bottom mount. The base crosspiece and large pedestal are in the way of the user's feet. Dual pedestal units take up even more room.
- Most adjustable workstations have two side legs, they are more expensive due to extra mechanisms and materials and require extra bracing and if they have dual adjustable surfaces the complexity, limitations and stability problems increase.
- Problems with prior art: non-adjustable, maintenance adjustable, manual and power adjustable workstations are either not capable of readily adjusting the work surface(s) or they do not have enough range of movement or appropriate movements that can conform to a majority of the population, children and shorter and taller people simply do not fit at inappropriate workstations.
- The easiest and most ergonomic way to adjust a workstation's height is with an electric drive(s) requiring only a switch(s) to operate. To utilize the full potential of electric drives, a workstation needs to be sturdy, stable and have enough range of adjustment to ergonomically accommodate the highest percentile, of users. An ergonomic computer workstation requires two movements with sufficient range: a movable main work surface and a monitor lift capable of raising the monitor to the ergonomically correct top of screen, eye level position.
- The invention's 45+/−degree angle of attachment(s) from the horizontal to the vertical element(s) presents the simplest, most torque resistant structural joining of workstation feet, legs and base. For use in business, home and schools, the invention's unique design was derived from the complex issues of cost and function in making a wheelchair accessible, computer workstation for schools (prior to receiving the USDE SBIR grant). The cost of changing workplace, school and other user stations to readily adjustable, motorized ergonomic workstations will be enormous so the invention utilizes the full potential of electric linear actuators in a new affordable adjustable workstation that will be of benefit to the market.
- It is especially noted that workstations are not available that can ergonomically adjust to fit children or shorter persons and also have the capability to readily adjust upwards to fit persons over 6 feet tall.
- The adjustable workstation system of the present invention increases the user's ability to achieve an ergonomically correct posture with a range of adjustments that are more inclusive of the general population and not age, height, ability or gender biased. Multiple users of the same workstation in the workplace, schools, families and individuals will benefit from the invention, which is also ADA compliant.
- The invention accomplishes this by using new unique structural elements and innovations that provide a vectored, torsion resistant, sturdy, stable base with a cantilevered electrically adjustable main work surface and an electrically adjustable monitor lift that travels with and raises above the main work surface for a greater combined range of adjustment; together they provide enough range of movement to accommodate most 6 year old children to adults over 6 feet tall. This is achieved without adding articulating keyboard trays, footrests, monitor arms, and etc.
- I have no knowledge of any adjustable workstation utilizing a design that significantly raises the bending moment of a single drive unit above its base or of a monitor lift that rises with and above the main work surface without obstructing the work surface.
- The invention is modular and can be configured for other uses. Horizontal bracing may be used in bases and especially in wider stance bases. Multi adjustable leg bases can be used for corner and long workstations and other embodiments. The adjustable embodiments of the invention can be utilized in other embodiments. The monitor lift can be made separable and utilized on other surfaces and embodiments.

In use, an operator can activate one or two of the four buttons at once; activating two of the four buttons, one for each of the two linear actuators achieve ++, −−, +− or −+ movements in the separate linear actuators, operating the actuators in tandem with up-up, down-down, up-down or down-up configurations. The ++ and −− combined movements are the quickest way to change work surface and monitor heights especially when changing from a short person to a tall person configuration or from a tall person to a short person configuration.
