Description
- This patent application claims the priority benefit of the filing date of a provisional application, Ser. No. 61/401,177, filed in the United States Patent and Trademark Office on Aug. 6, 2010.
- The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment of any royalty thereon.
- With the advances in computer and display technology, and the dramatic shift in people's work responsibilities and task demands, small, standard computer monitors are no longer the norm because they no longer meet the demands of the workplace. In fact, there has been an increasing trend in the integration of large displays into the workplace. However, while there has been a great deal of work conducted on designing ergonomically friendly office furniture, to date no published guidelines exist for large display workstations. What works for a small monitor does not work for a large monitor. For example, maintaining a 20 inch viewing distance (recommended for small computer displays) in front of a 56 inch display creates significant visual discomfort for the user. Moreover, utilizing traditional workstation design for large displays will not allow the user the ability to view the entire computer screen. An ergonomically designed workstation is of paramount importance to the productivity, safety, and satisfaction of those who would use it, especially when used for extended periods of time. In the absence of an ergonomically designed workstation, potential side effects and physical problems include, but are not limited to, neck and shoulder pain, lower back pain, and strain of the wrists. Therefore, what is needed is an ergonomically designed workstation compatible with large computer monitors.
- There have been various attempts to design ergonomic computer workstations. Some such workstations facilitate different orientations of the computer monitor relative to the user.
- U.S. Pat. No. 5,450,800 to Leonard (hereinafter Leonard) discloses an ergonomically adjustable computer workstation having a means to vary both the height and angle of the monitor support platform. The invention in Leonard neither provides nor discloses any means for supporting a keyboard.
- U.S. Pat. No. 5,845,586 to Moore (hereinafter Moore) discloses an ergonomic workstation having means for keyboard height and angle adjustment. The invention in Moore discloses no means for adjustment of monitor height or angle.
- U.S. Pat. No. 5,174,223 to Nagy (hereinafter Nagy) discloses an ergonomic computer workstation for standing and sitting operators. The invention in Nagy utilizes a monitor support with a vertical lift means to raise and lower the monitor height. The Nagy invention also utilizes a keyboard support with a means for adjusting the inclination of the keyboard. In the Nagy invention, however, the keyboard height is neither separately adjustable in height from the monitor height nor is it horizontally extendable in any fashion whatsoever.
- U.S. Design Pat. D371,255 to Richard (hereinafter Richard) discloses a design for an ergonomic computer workstation having separate and apparently movable means for supporting a monitor and keyboard support shelf relative to a “seated' user. The Richard design discloses no features which would suggest the design is capable of accommodating users in the standing position.
- U.S. Design Pat. D459,610 to Coonan et al (hereinafter Coonan) discloses a design for a vertically adjustable computer workstation which depicts an apparent means for vertical height adjustment of the monitor and keyboard in unison, without any apparent means to adjust the height of the monitor and keyboard independently of each other. There is no apparent means for horizontal keyboard extension.
- U.S. Pat. No. 6,374,752 to Walser (hereinafter Walser) discloses an ergonomic computer workstation having a power lift means to provide vertical height adjustment of both the computer monitor and keyboard supports. Walser also discloses using a gas pressure lift mechanism to provide vertical lift of the workstation. The invention in Walser discloses no means to provide vertical lift of the computer monitor independently of the vertical height of the keyboard. Additionally, Walser provides no means to extend or retract the keyboard in the horizontal direction. Nor does the invention in Walser accommodate large computer monitor displays, nor operators in the standing position.
- U.S. Pat. No. 6,098,936 to Birrell (hereinafter Birrell) discloses an ergonomic workstation having an independently rotatable monitor and keyboard support means. The keyboard support means also incorporates vertical height adjustment means. The keyboard support means has no provision for extending in the horizontal direction.
- U.S. Pat. No. 5,857,415 to Richard (hereinafter Richard) discloses an ergonomic computer workstation having a means for varying the height and angle of both the monitor support shelf and the keyboard support shelf relative to a “seated’ user. Richard discloses no means for nor appears to be mechanically capable of accommodating users in the standing position. In this same regard, the invention in Richard provides no means to elevate a large computer display to the proper viewing height.
- In view of the deficiencies of the above described prior art, what is needed therefore is an apparatus which can facilitate the effective viewing of very large computer displays from either a standing or sitting operator orientation while still retaining portability and mobility.
- One objective of this present invention is to provide an apparatus for facilitating the operation of computer systems connected to very large display systems.
- Another objective of the present invention is to provide an apparatus for operating computer systems connected to very large display systems while the operator is either standing or sitting.
- Yet another objective of the present invention is to provide an apparatus for facilitating the operation of computer systems connected to very large display systems in which the monitor height and keyboard height are independently adjustable vertically, horizontally, and angularly relative to the operator.
- Still another objective of the present invention is to provide an apparatus for facilitating the operation of computer systems connected to very large display systems which can collapse for transportability and mobility.
- Briefly stated, the present invention provides an apparatus for facilitating the operation of computer systems connected to very large display systems. The invention comprises monitor and keyboard supports which are independently adjustable vertically, horizontally, and angularly. The keyboard support is designed to allow the monitor to pass therethrough and/or behind for any given vertical, horizontal, or angular orientation of the monitor relative to the keyboard. The invention is configurable to facilitate operators in the standing or sitting positions and can collapse to allow mobility through typical doorways.

FIG. 1 , the preferred embodiment present invention comprises a large screen computer monitor stand with a telescoping work surface 130 (i.e., keyboard/mouse and forearm support assembly) that can be extended arbitrary distances from the monitor or otherlarge screen display 170, where up to 45″ is typical for one embodiment, though it is within the scope of the present invention to extend to greater distances. Themonitor 170 andwork surface 130 can also be adjusted to various height positions independently of each other. This permits users of various anthropometric characteristics to use it in various sitting and standing positions. The entire system is oncasters 150 for portability. The monitor attachment means 100 can be tilted and locked into any position in the range of 15° backward to 5° forward giving the monitor 170 a like angular displacement. The tilting monitor attachment means 100 is derived from a commercial product that was modified to provide the amount of backward tilt required. The monitor lift system, or extensible support, 120 is a commercial product attached to the base of the unit. The worksurface lift system 110, is also an alternately extensible and retractable structure, being attached to thebase 140, and used to adjust the work surface height and is also commercially available. In one embodiment twoextensible supports 120 are employed in the monitor lift system and fourextensible supports 110 are employed in the work surface lift system with two on each side. However, it is well within the scope of the invention and those skilled in the art to fashion any number and configuration of extensible supports to lift and lower the monitor attachment means and worksurface. The complete system described by the present invention herein is unique because it integrates these parts with a telescoping or articulatingwork surface 130 that allows the use of alarge screen display 170 for a variety of computer desktop activities and collapses to a depth of 32.5″ in one embodiment to allow it to fit through a standard 3′ doorway for improved portability via wheels, casters, orrollers 150. - Still referring to

This configuration would be suitable, but not limited to, when using the present invention for display to an audience. Positioning themonitor 170 andwork surface 130 at their highest positions is coincident with the first verticallyextensible support 120 and second verticallyextensible support 110 being fully extended. Themonitor 170 andwork surface 130 heights can each be adjusted independently and at any position within the minimum and maximum height range. - Referring to
FIG. 3 shows a side view of the present invention with themonitor 170 and thework surface 130 at their lowest positions with thework surface 130 partially extended. - Referring to
FIG. 4 shows a side view of the present invention with themonitor 170 and thework surface 130 at their lowest positions and with thework surface 130 fully extended. This configuration would be suitable, but not limited to, when using the present invention while sitting as the full extension of thework surface 130 allows an unobstructed view of themonitor 170 even while seated. - Referring to
FIG. 5 shows a side view of the present invention utilized by a user in the seated position with thework surface 130 fully extended and monitor 170 angled via the function of the monitor attachment means 100. - Referring to
FIG. 6 shows a side view of the present invention utilized by a user in the seated position with thework surface 130 fully extended and monitor 170 not angled (i.e., perpendicular to horizontal) via the function of the monitor attachment means 100. Thework surface 130 can be positioned anywhere within the range from fully retracted to fully extended and locked in place. - Referring to
FIG. 7 shows a top view of the present invention with thework surface 130 in a fully retracted position. It should be noted that the horizontal extensibility means of thework surface 130 permits themonitor 170 to pass through without interference therebetween, thereby facilitating independent vertical height adjustment of themonitor 170 andwork surface 130. - Referring to
FIG. 8 shows a top view of the present invention with thework surface 130 in a fully extended position. It should be noted that the present invention allows for full viewing of themonitor 170 from a seated position if thework surface 130 is fully extended. - Referring to
FIG. 9 shows a front view of the present invention. It should be noted that the horizontal extensibility means of thework surface 130 permits themonitor 170 to pass through without interference therebetween, thereby additionally facilitating themonitor 170 andwork surface 130 to be stowed in a compact configuration having minimal dimensions. - Referring to
FIG. 10 shows the rear of present invention. An articulatingguide 160 houses, protects, and keeps orderly power and signal cables running from the computer (not shown) to themonitor 170. The articulating guide may be comprised of a plurality of sections, all such configurations being within the scope of the present invention.FIG. 10 depicts the articulatingguide 160 in a fully extended configuration coincident with the verticallyextensible supports 120 being fully extended so as to raise themonitor 170 to a maximum height. - Referring to
FIG. 11 shows the rear of present invention depicting the articulatingguide 160 in a fully collapsed configuration coincident with the verticallyextensible supports 120 being fully retracted so as to lower themonitor 170 to a minimum height. - Referring to
FIG. 12 shows photographs of the reduced-to-practice present invention that was developed in use with a standing and sitting user. - The present invention allows a wide variety of users to comfortably use a large-display workstation in both sitting and standing positions. None of the prior art inventions claim or disclose any means for standing and sitting while using the very large monitors accommodated by the present invention. The particular prototype of the present invention that was built was intended to allow greater use of a high resolution 56″ LCD display that could not be effectively used as computer monitor for routine software development and testing. The present invention is not limited to 56″ monitors, however, as any size monitor may be used. Typically displays this large are not used as desktop monitors in a seated position. Based on ergonomic principles the viewing area of the monitor should be between 15° and 50° below horizontal eye level. A downward gaze angle improves a user's ability to accommodate and converge. This requires the bottom of a 56″ display to be positioned below the work surface as illustrated in
FIG. 5 andFIG. 6 . Appropriate viewing distance is also much further away than conventional prior art computer furniture allows. With a viewing distance of up to 45″, the user is able to view the entire computer screen without any portion(s) of the telescoping work surface blocking the bottom portion of the screen by virtue of the design of the telescoping/articulating means of thework surface 130. The present invention allows greater utilization of high-resolution large screen displays by not limiting their use solely for presentation and group viewing. Although designed around a 56″ display, the same design principles would be within the scope of the present invention to build a workstation for both smaller and even larger displays to accommodate a wider range of users and applications than traditional computer furniture, including that disclosed by the prior art. - Initial research to locate a commercial-off-the-shelf solution revealed several alternatives for height-adjustable workstations, including products available from AFC Industries (http://afcindustries.com/), Anthro Technology Furniture (http://www.anthro.com/), and Biomorph Interactive Desk (http://www.biomorphdesk.com/height_adjustable_desks.html). Existing vendor offered custom solutions for independently adjustable monitors and keyboard tray lifting systems. However, the manufacturers of prior art products do not offer any solutions to accomplish the work surface (or keyboard tray) extension requirement provided by the articulation means of
work surface 130, nor the monitor tilt provided by the monitor attachment means 100, nor the compact footprint, all being features of the present invention. Thework surface 130 extension requirement of the present invention was completely devoid in any manufacturer's adjustable computer furniture. To solve this requirement, the present invention utilizes a unique design which employs linear actuators to raise and lower thework surface 130 and monitor 170 independently, but with the added benefit of a heavy-duty telescoping or articulating mechanism to extend thework surface 130 to the required distance. The present invention also comprises features to allow its base to be small enough to fit through a standard doorway, but, by using material that would lower the center-of-gravity, to prevent it from being top heavy when the monitor is at its highest position. - Relative to the solutions provided by the prior art, and their limitations, the present invention represents a unique integration of components designed to provide an appropriate viewing distance for such a large display. Durability and portability are important features that have been integrated in the present invention. In particular, in addition to having minimal footprint, allowing the invention to fit through a standard 3′ door (when collapsed) the design is very flexible during transportation, especially when used for non-office related work, such as presentations and collaborative meetings.
