ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a portable table for holding various objects. More particularly, the invention relates to a compact, portable computer stand for supporting laptop computers and associated components.
BACKGROUND OF THE INVENTION
In recent years the laptop portable personal computer, or simply “laptop” to which it is generally referred, has become an increasingly popular tool used by executives, salespersons, engineers, students, accountants, teachers, homemakers, lawyers and other business and professional persons. The laptop is very compact and was designed to rest in the user's lap so that the user has a “built-in” place for supporting the laptop when the user is seated. While this “built-in” supporting spot is convenient, it has many drawbacks. For one, the user's legs must be held still in order to keep the laptop from moving around. This is uncomfortable and can be a tiring exercise. Additionally, the user must have good balance to maintain the laptop in a position which can be particularly difficult when the user is using the laptop in conjunction with reading notes, books or other materials, as is often the case.
Other stands have been disclosed such as the one described by U.S. Pat. No. 5,054,736 which provides a laptop reading and writing stand, yet it suffers from the same problems connected with laptop computers because it rests on the lap of the user. Additionally, stands for computers are disclosed in U.S. Pat. Nos. 5,100,098 and 5,357,873; however, since neither of these patents specifically deal with laptops neither solves the above-described problems associated with laptop computers.
Workstations have been designed for laptops as shown in U.S. Pat. Nos. 4,830,328, 5,379,893, 5,445,266 and 5,470,041 which generally disclose workstations for supporting a laptop on a permanent desktop or table located in a business or residential environment. U.S. Pat. No. 4,830,328 also discloses the attachment of a pipe flange or straight coupling to the first plate to allow mounting to a tripod.
The foregoing patents demonstrate that there is a need for a computer stand that is compact, stable, lightweight, foldable, and has adjustable height.
BRIEF SUMMARY OF THE INVENTION
According to one embodiment of the present invention, a support for a portable laptop computer is provided which provides a table top having a generally planar upper surface for supporting a conventional portable computer in a horizontal position for facilitating use of the portable computer. The table top has an inner surface and a side lip circumscribing the upper surface and extending perpendicularly downward, thereby forming within a concave leg retaining cavity. A pair of parallely arranged, pivotally affixed leg assemblies attach pivotally to said lower surface such that the leg assemblies can be folded within said concave leg retaining cavity for storage of said support stand.
