Abstract
Abstract A keyboard assembly for a computer with movable keyboard pallets. The pallets are movable relative to each other between a compact stowing position and an extended operational position. A movement mechanism moves at least one of the pallets in a lateral direction relative to the other pallet and then towards the other pallet in a direction orthogonal to the lateral direction. The movement mechanism can be connected to the cover of the computer to automatically control movement of the pallets based upon position of the cover relative to a base of the computer. Thus, the pallets can be automatically moved from the compact stowing position, when the cover is closed, to the extended operational position when the cover is opened. Upon moving the cover from the open position to the closed position, the pallets are automatically moved from the extended operational position to the compact stowing position. The movement mechanism includes a drive arm with a spring section. The spring section allows the pallets to be biased toward each other in their stowing position. The spring section is preloaded such that it does not function as a spring until a predetermined force is applied to the spring section.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
In an electronic device having a housing, electronic circuitry, and a keyboard assembly, the keyboard assembly having keyboard pallets, at least one of the keyboard pallets being movably connected to the housing, the improvement comprising: means for biasingly loading the movable keyboard pallet at a position on the housing, wherein the means for biasingly loading spring biases the movable keyboard pallet against another one of the keyboard pallets and includes an arm with a preloaded spring section, wherein the preload spring section includes two spaced arm portions extending to an end of the arm.
Claim 2
Dependent Claim
94 words
In an electronic device having a housing, electronic circuitry, and a keyboard assembly, the keyboard assembly having keyboard pallets, at least one of the keyboard pallets being movably connected to the housing, the improvement comprising: means for biasingly loading the movable keyboard pallet at a position on the housing, wherein the means for biasingly loading spring biases the movable keyboard pallet against another one of the keyboard pallets and includes an arm with a preloaded spring section, wherein the preload spring section includes two spaced arm portions extending to an end of the arm.
Claim 3
Dependent Claim
25 words
A device as in claim 1 wherein the means for biasingly loading includes a deflectable portion of an arm of a keyboard pallet movement mechanism.
Claim 4
Dependent Claim
19 words
A device as in claim 2 wherein the deflectable portion is preloaded against another member of the movement mechanism.
Claim 5
Dependent Claim
15 words
A device as in claim 3 wherein the arm is pivotably connected to the housing.
Claim 6
Dependent Claim
38 words
A device as in claim 4 wherein the arm is a second drive arm, the other member is a first drive arm, and a first end of the first drive arm is connected to the second drive arm.
Claim 7
Dependent Claim
21 words
A device as in claim 1 wherein the end of the arm has a general ball shape with a slot therethrough.
Claim 8
Dependent Claim
35 words
A device as in claim 1 wherein a first one of the spaced arm portions is substantially rigid and a second one of the spaced arm portion is flexible towards the first spaced arm portion.
Claim 9
Dependent Claim
74 words
In a computer having a housing, a display, electronic circuitry, and a reconfigurable keyboard assembly, the improvement comprising: the reconfigurable keyboard assembly having a movement mechanism for moving a movable keyboard pallet of the assembly on the housing, the movement mechanism having a preloaded spring section for biasing the movable keyboard pallet at a predetermined position, wherein the preloaded spring section is comprised of a portion of a drive arm of the movement mechanism.
Claim 10
Dependent Claim
74 words
In a computer having a housing, a display, electronic circuitry, and a reconfigurable keyboard assembly, the improvement comprising: the reconfigurable keyboard assembly having a movement mechanism for moving a movable keyboard pallet of the assembly on the housing, the movement mechanism having a preloaded spring section for biasing the movable keyboard pallet at a predetermined position, wherein the preloaded spring section is comprised of a portion of a drive arm of the movement mechanism.
Claim 11
Dependent Claim
20 words
A computer as in claim 8 wherein the preload spring section includes two spaced arm portions of the drive arm.
Claim 12
Dependent Claim
37 words
A computer as in claim 9 wherein a first one of the spaced arm portions is substantially rigid and a second one of the spaced arm portions is at least partially deflectable towards the first arm portion.
Claim 13
Dependent Claim
50 words
A computer as in claim 9 wherein ends of the arm portions are located inside a receiving area of another member of the movement mechanism, at least one of the arm portions being deflected relative to the other arm portion and preloaded against the other member inside the receiving area.
Claim 14
Dependent Claim
23 words
A computer as in claim 11 wherein the other member is another drive arm that is pivotably connected to the movable keyboard pallet.
Claim 15
Dependent Claim
76 words
A reconfigurable keyboard assembly comprising: two keyboard pallets, a first one of the pallets being movably connected to a second one of the pallets; a movement mechanism for moving the first pallet relative to the second pallet; and means for biasing the first pallet at a predetermined position relative to the second pallet, wherein the means for biasing includes a preloaded spring that comprises a member of the movement mechanism that has a deflectable cantilevered section.
Claim 16
Dependent Claim
76 words
A reconfigurable keyboard assembly comprising: two keyboard pallets, a first one of the pallets being movably connected to a second one of the pallets; a movement mechanism for moving the first pallet relative to the second pallet; and means for biasing the first pallet at a predetermined position relative to the second pallet, wherein the means for biasing includes a preloaded spring that comprises a member of the movement mechanism that has a deflectable cantilevered section.
Claim 17
Dependent Claim
23 words
A keyboard assembly as in claim 13 wherein the member includes a substantially rigid cantilevered section generally parallel with the deflectable cantilevered section.
