Abstract
Abstract A portable, three layered laptop computer assembly includes a keyboard member pivotably attached to an output member and provided with an intermediate display member. Upon opening the three members from a closed position with the members forming a regular cubic configuration, the keyboard and output members will be disposed with their bottom surfaces co-planar while the display member attached to the mount member is automatically positioned in a substantially vertical manner.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
107 words
A three layered laptop computer assembly, comprising: a keyboard component and an output component, a mount element disposed intermediate said keyboard and output components, hinge means respectively joining said mount element to said keyboard and output components, and a display component attached to said mount element, whereby displacement of said keyboard and output components substantially 90 degrees about said hinge means alters said assembly between an open use position with said keyboard and output components substantially co-planar and said display component supported vertically, to a closed position with said display component sandwiched between said keyboard and output components with all three components defining a regular cubic configuration.
Claim 2
Dependent Claim
107 words
A three layered laptop computer assembly, comprising: a keyboard component and an output component, a mount element disposed intermediate said keyboard and output components, hinge means respectively joining said mount element to said keyboard and output components, and a display component attached to said mount element, whereby displacement of said keyboard and output components substantially 90 degrees about said hinge means alters said assembly between an open use position with said keyboard and output components substantially co-planar and said display component supported vertically, to a closed position with said display component sandwiched between said keyboard and output components with all three components defining a regular cubic configuration.
Claim 3
Dependent Claim
17 words
