Abstract
Abstract The present invention relates to a separable keyboard and computers having this separable keyboard which can be separated into two parts. This invention is particularly directed towards notebook or lap top computers. An essential feature of this invention is that the user can control the amount and degree to which the two keyboard halves are separated. Additional features include designs that allow the user to sense whether the keyboards are separating or locking into one of several possible discrete positions, and designs that prevent the keyboard halves from swerving or wobbling.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
113 words
A separable keyboard, comprising: a keyboard separable into right and left sections, said keyboard having a top side and a bottom side, each section of said top side having a plurality of keys disposed thereon and each section of said bottom side having an adjustment shaft protruding therefrom; and a base having both left and right portions, each portion of said base being perforated by a plurality of adjustment slots, each of said adjustment slots having a plurality of discrete positions, said adjustment shafts being inserted into respective adjustment slots, allowing sidewalls of said adjustment slots to flex and enabling said adjustment shafts to be sequentially positioned into said plurality of discrete positions.
Claim 2
Dependent Claim
113 words
A separable keyboard, comprising: a keyboard separable into right and left sections, said keyboard having a top side and a bottom side, each section of said top side having a plurality of keys disposed thereon and each section of said bottom side having an adjustment shaft protruding therefrom; and a base having both left and right portions, each portion of said base being perforated by a plurality of adjustment slots, each of said adjustment slots having a plurality of discrete positions, said adjustment shafts being inserted into respective adjustment slots, allowing sidewalls of said adjustment slots to flex and enabling said adjustment shafts to be sequentially positioned into said plurality of discrete positions.
Claim 3
Dependent Claim
56 words
The separable keyboard of claim 1, said left and right portions of said base each having a pair of recess slots parallel to, adjacent, and on each side of said adjustment slots, said pair of recess slots providing elasticity to said sidewalls of said adjustment slots when said adjustment shafts are moved within respective adjustment slots.
Claim 4
Dependent Claim
115 words
The separable keyboard of claim 2, said left and said right portions further comprising: a pair of swerve preventative projecting shafts protruding from the bottom side of each section of said keyboard; and a first and a second guiding slot in said base plate, said first and said second guiding slots being parallel to said adjustment slot and said pair of recess slots, one of said pair of swerve preventative projecting shafts being inserted into said first guiding slot and the other of said pair of swerve preventative projecting shafts being inserted into said second guiding slot to prevent each one of said pair of keyboard sections from being inadvertently removed from said base plate.
Claim 5
Dependent Claim
15 words
The separable keyboard of claim 3, said adjustment slot traces an arc of a circle.
Claim 6
Dependent Claim
66 words
The separable keyboard of claim 4, a first elastic portion being formed between said adjustment slot and one of said pair of recess slots and a second elastic portion being formed between said adjustment slot and said other of said pair of recess slots allowing said first and said second elastic portions to flex as said adjustment shaft is moved between said plurality of discrete positions.
Claim 7
Dependent Claim
100 words
A separable keyboard structure for a notebook computer, comprising: a base, each half of said base being perforated by an adjustment slot, said adjustment slot having resilient and flexible sidewalls providing a plurality of successive discrete positions; and a keyboard separable into two halves, each half having a top side and a bottom side, said top side having a plurality of keys disposed thereon, said bottom side of each half having a adjustment shaft protruding from said bottom side, said adjustment shaft engaging said adjustment slot of said base and successively moving into said discrete positions in said adjustment slot.
Claim 8
Dependent Claim
100 words
A separable keyboard structure for a notebook computer, comprising: a base, each half of said base being perforated by an adjustment slot, said adjustment slot having resilient and flexible sidewalls providing a plurality of successive discrete positions; and a keyboard separable into two halves, each half having a top side and a bottom side, said top side having a plurality of keys disposed thereon, said bottom side of each half having a adjustment shaft protruding from said bottom side, said adjustment shaft engaging said adjustment slot of said base and successively moving into said discrete positions in said adjustment slot.
Claim 9
Dependent Claim
