Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to furniture or supporting structure for supporting personal computers and peripheral equipment for use. The structure, combined with a chair for seating a person, creates a stationary yet movable workstation. The invention finds greatest utility in residences and also office, retail, and other utilitarian work places which require that a personal computer be utilized or are intended to have a personal computer operated therein, but which places are not previously configured as workstations. Any general purpose building, including residential, institutional, commercial, and industrial, may be improved to support personal computers by utilizing the present invention.




2. Description of the Prior Art




Personal computers are becoming increasingly integrated into the commercial economy and also utilized by private consumers for their own purposes and also to interface with the commercial economy. Ergonomics and other practical considerations require that computers be placed on a desk or other suitable working environmental furniture or structure. However, chairs provided for use with desks may possibly not be ergonomically suitable for extended periods of computer use. Many people would prefer to adapt large cushioned or padded chairs of the type typically found in the home to computer use. However, most desks and other supporting structure intended for use with personal computers are not dimensioned and configured to cooperate suitably with computers or indeed to accommodate work related surfaces.




The prior art has suggested approaches to adapt chairs to desk work. An example is seen in U.S. Pat. No. 4,932,718, issued to Ryokichi Yamazaki on Jun. 12, 1990, featuring a coupled chair unit. The chair unit has work surfaces which may be selectively swung into a position suitable for writing, and retracted from the operative position. The chair unit of Yamazaki lacks the versatile adjustability of proximity and angle for a work surface and for a separate monitor support surface, as seen in the present invention.




U.S. Pat. No. 3,435,783, issued to Cecil L. Kollenborn on Apr. 1, 1969, shows a tabletop supported on a stand which can be slid into proximity with a chair, for writing and similar tasks. Proximity to the chair is adjusted only by moving the entire stand. By contrast, the present invention enable adjustment without moving the entire device. The present invention further has two independently adjustable work supporting surfaces, rather than the single surface of Kollenborn.




Combined chairs and working surfaces are seen in U.S. Design Pat. No. 140,524, issued to Auburn Taylor on Mar. 6, 1945, U.S. Pat. No. 207,262, issued to Robert A. Maurer et al. on Mar. 28, 1967, U.S. Pat. No. 230,383, issued to Lyle A. Atkinson on Feb. 19, 1974, U.S. Pat. No. 236,566, issued to Warren D. Parchan on Sep. 2, 1975, and U.S. Pat. No. 250,230, issued to Stine Kotula on Nov. 14, 1978. In each case, a working surface supported on an easy chair or the like is provided. However, by contrast, the present invention lacks the chair itself, and has two independent work supporting surfaces adjustably mounted on two spaced apart posts.




None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.




SUMMARY OF THE INVENTION




The present invention sets forth a support structure which supports a personal computer and related peripherals in the organized manner of a workstation. The support structure positions a computer monitor, keyboard, and mouse, and related apparatus such as printer, adjustably and advantageously around a chair. Because of adjustable positioning, any chairs including lounge and “easy” chairs, and even wheelchairs, may be employed as part of the workstation. The work surfaces, and hence the keyboard and monitor, may be positioned exactly according to a user's wishes. Therefore, the user is afforded both convenience and also comfort wherever a computer workstation is to be established.




The support structure has two work surfaces supported on separate telescoping posts, and a table mounted on a third telescoping post. The first and second posts incorporate swing arms that enable their respective work surfaces to be infinitely adjustable as to proximity to their posts. Height of all of the posts is adjusted by securing telescoping post members at selected heights. One work surface can be inclined to suit.




Auxiliary features include cup holders, drawer, ashtray holder, pen and pencil tray, a drawer for stowing the keyboard and mouse, a speaker stand for accommodating speakers, clips for securing papers to a work surface, additional storage space in the form of a hutch and closed cabinet, wire covers for protecting signal and power cables, and optional power supplies and associated extension cables. In a further option, the swing arms are powered, so that handicapped users can readily adjust proximity of the work surfaces.




Accordingly, it is one object of the invention to provide structure for supporting a personal computer in proximity to a chair not originally designed to cooperate with a computer support.




It is another object of the invention that the support structure be adjustable so that computer components are positioned exactly according to a user's wishes.




It is a further object of the invention to accommodate small personal and work articles on the support structure.




Still another object of the invention is to accommodate the needs of the handicapped in a computer workstation.




It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.




These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

comprises a flat base


12


having at least two posts


14


,


16


attached to and projecting upwardly from base


12


. Posts


14


,


16


each have a respective panel


18


or


20


having a flat upper work surface


22


or


24


affixed thereto. As illustrated, work surface


24


supports monitor


4


. Work surface


22


is advantageously employed to support a keyboard and mouse.




Posts


14


,


16


each have means for adjusting both height and also proximity of work surface


22


or


24


relative to their associated posts


14


or


16


. Each post


14


or


16


is formed in two telescoping sections such that overall height of the post


14


or


16


may be adjusted in a vertical direction exemplified by arrows


26


,


28


. Setscrews


30


,


32


are tightened to secure the sections of posts


14


,


16


in selected axial relationship relative to arrows


26


,


28


and also to prevent mutual rotation between the sections.




The upper section of each post


14


or


16


has assemblies associated therewith for adjusting proximity of its respective work surface


22


or


24


relative to the longitudinal axis of its associated post


14


or


16


. This arrangement will be described with respect to post


16


, it being understood that post


14


is functionally similar. A first swing arm


34


is connected to and projects laterally from a socket


35


rotatably mounted on the upper section of post


16


. Swing arm


34


terminates in a socket arrangement wherein a pivotal socket


36


is pivotally supported on a base


38


. Socket


36


and base


38


may include, for example, a concealed pin fixed to base


38


about which socket


36


may freely rotate such that a second swing arm


40


swings through a horizontal plane. Second swing arm


40


terminates in a socket arrangement equivalent to that of socket


36


. However, socket


42

,


36


are arranged such that swing arm


34


rotates about the longitudinal axis of post


16


, and swing arm


38


rotates independently about the longitudinal axis of socket


36


. A compound motion is thus enabled which enables panel


20


to be adjusted selectively at any desired proximity to post


16


, within a range determined by the combined lengths of swing arms


34


,


40


. It is intended that panel


20


will be adjusted so that monitor

is located at the most convenient location for a user seated in chair


2


. It should be noted that setscrew


32


is also utilized to establish an optimum height of platform


24


above base


12


. Post


14


may similarly be adjusted so that panel


18


is suitably and conveniently positioned to afford ergonomic proximity of a keyboard and mouse.




Panel


18


and hence work surface


22


may be inclined relative to horizontal orientation in the following way. A support arm


44


projects from socket


46


of post


14


. A collar


48


rigidly attached to panel


18


encircles arm


44


. Collar


48


and panel

can be rotated about the longitudinal axis of arm


44


. A setscrew


50


is tightened when work surface


22


is at a selected degree of inclination.




It will be appreciated that chairs are available in many configurations and dimensions. Therefore, it is desirable to enable adjustment of length of base


12


, in that length relates to spanning the width of chair


2


. When base


12


is adjusted, posts


14


,


16


are selectively spaced apart to a desired interval of separation.

FIG. 2

shows structure enabling base


12


to be adjusted. Base


12


is formed in right and left sections


54


,


56


each bearing a series of spaced apart holes


58


. A spanning member


60


has downwardly facing projections


62


which are configured and dimensioned to enter and cooperate closely with holes


58


. When sections


54


,


56


are spaced apart at a desired interval, member


60


is placed over sections


54


,


56


and pressed downwardly until projections


62


enter some of the holes


56


, thereby locking sections


54


,


56


in the selected position.




Returning to
