Abstract

Abstract A retrofitting, folding, portable keyboard for a notebook computer consists of two, pivotally-hinged halves. The two halves are hinged so that may be assume a perfectly flat, horizontal position, or, alternatively, a laterally raised and sloping configuration that provides an enhanced, ergonometric configuration to the user. Each half has its own set of keys and space bar. The keyboard of the invention has its own pointing device that takes over the pointing function of the pointing device of the dedicated keyboard provided with the notebook computer. The portable, folding keyboard of the invention also has a joystick-adapter by which a conventional joystick may be operatively coupled to the notebook computer by which games may be played. Four, bottom, pivotal feet support the keyboard on and/or above the existing keyboard provided with the notebook computer. A carrying case is provided in which the folded-up keyboard may be stored and transported. Also provided is a dual split screen, where each half of the split screen is pivotally mounted for universal rotation.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 186 words
In a portable, notebook or portable computer having a main frame comprising an upper surface upon which is provided a keypad, the improvement comprising: display-screen means pivotally mounted to said main frame, said display-screen means comprising a pair of independently mounted screen-halves; mounting means for independently pivotally mounting said screen-halves to said main frame; said mounting means comprising a first portion for pivotally mounting a first said screen-half to a first section of said main frame in a first direction, and a second portion for pivotally mounting a second said screen-half to a second section of said main frame in said first direction, said mounting means allowing said screen-halves to pivot independently of each other in an upward direction for display, and in a downward direction for abutting contact against said upper surface of said main frame for storage and transport; said mounting means also comprising a at least one joint means for said first portion of said mounting means for allowing said first said screen-half rotation in a second direction perpendicular to said first direction when said first screen-half is pivoted in said upward direction.
Claim 2
Dependent Claim 186 words
In a portable, notebook or portable computer having a main frame comprising an upper surface upon which is provided a keypad, the improvement comprising: display-screen means pivotally mounted to said main frame, said display-screen means comprising a pair of independently mounted screen-halves; mounting means for independently pivotally mounting said screen-halves to said main frame; said mounting means comprising a first portion for pivotally mounting a first said screen-half to a first section of said main frame in a first direction, and a second portion for pivotally mounting a second said screen-half to a second section of said main frame in said first direction, said mounting means allowing said screen-halves to pivot independently of each other in an upward direction for display, and in a downward direction for abutting contact against said upper surface of said main frame for storage and transport; said mounting means also comprising a at least one joint means for said first portion of said mounting means for allowing said first said screen-half rotation in a second direction perpendicular to said first direction when said first screen-half is pivoted in said upward direction.
Claim 3
Dependent Claim 42 words
The portable, notebook or portable computer according to claim 1, wherein said mounting means comprises a first and second joint means, each of said first and second joint means comprising a universal joint allowing a full 360-degree rotation for each said screen-half.
Claim 4
Dependent Claim 28 words
The portable, notebook or portable computer according to claim 1, wherein said at least one joint means allows said at least one screen-half at least 180 degrees rotation.
Claim 5
Dependent Claim 238 words
In a portable, notebook or portable computer having a main frame comprising an upper surface upon which is provided a keypad, the improvement comprising: said main frame comprising a first half and a second half, said first and second halves being pivotally connected to each other, said main frame comprising medially-mounted, first pivot-mounting means for pivotally mounting said first and second halves, whereby the main frame may be folded for convenient storage, and unfolded for use; display-screen means mounted to said main frame, said display-screen means comprising a pair of independently mounted screen-halves; second mounting means for mounting said screen-halves to said main frame; said second mounting means comprising a first portion for pivotally mounting a first said screen-half to a first section of said main frame, and a second portion for mounting a second said screen-half to a second section of said main frame, said first and second portions of said second mounting means allowing said first screen-half to pivot independently of the other said screen-half in an upward direction for display, and in a downward direction for abutting contact against said upper surface of said main frame for storage and transport; said second mounting means also comprising a joint means for at least said first portion of said second mounting means for allowing the first said screen-half rotation in a direction transverse to said upward direction when said first screen-half is pivoted in said upward direction.
Claim 6
Dependent Claim 238 words
In a portable, notebook or portable computer having a main frame comprising an upper surface upon which is provided a keypad, the improvement comprising: said main frame comprising a first half and a second half, said first and second halves being pivotally connected to each other, said main frame comprising medially-mounted, first pivot-mounting means for pivotally mounting said first and second halves, whereby the main frame may be folded for convenient storage, and unfolded for use; display-screen means mounted to said main frame, said display-screen means comprising a pair of independently mounted screen-halves; second mounting means for mounting said screen-halves to said main frame; said second mounting means comprising a first portion for pivotally mounting a first said screen-half to a first section of said main frame, and a second portion for mounting a second said screen-half to a second section of said main frame, said first and second portions of said second mounting means allowing said first screen-half to pivot independently of the other said screen-half in an upward direction for display, and in a downward direction for abutting contact against said upper surface of said main frame for storage and transport; said second mounting means also comprising a joint means for at least said first portion of said second mounting means for allowing the first said screen-half rotation in a direction transverse to said upward direction when said first screen-half is pivoted in said upward direction.
