Keyboard device
First Claim
1. A keyboard device, comprising:
- a keyboard case presenting a widened expanse;
switch groups each including at least two key switches, said at least two key switches arranged along a longitudinal direction of each of said switch groups, said at least two key switches including bases attached to one another for maintaining said at least two key switches in fixed spaced apart relation to one another within respective ones of said switch groups; and
at least a portion of said switch groups slidably mounted to said keyboard case to permit mounted movement thereof relative said keyboard case along a keyboard axis, said switch groups being disposed in positions laterally adjacent one another and with said longitudinal axes thereof oriented crosswise said keyboard axis to collectively form at least a portion of a keyboard pattern, slidable mounted movement of said at least a portion of said switch groups relative one another thereby changing a dimension of said keyboard pattern in a direction of said keyboard axis.

Abstract
An expandable and retractable keyboard permits alteration of an overall size thereof by permitting relative sliding movement of keys mounted to a keyboard case. Switch groups each includes at least two key switches arranged along a longitudinal direction of a respective switch group. Bases of the key switches in each switch group are connected with an adjacent one, thereby maintaining the key switches in a given group in fixed spaced apart relation to one another. At least a portion of the switch groups are slidably mounted to the keyboard case to permit mounted movement thereof relative the keyboard case along a keyboard axis. The slidably mounted switch groups are disposed in positions laterally adjacent one another, thereby collectively forming at least a portion of a keyboard pattern. Slidable mounted movement of the switch groups relative one another effects a change in dimension of the keyboard pattern in a direction of the keyboard axis. A further feature permits adjustment of a key height by placement of a leaf spring below a key top, wherein sliding displacement of the key switches removes upward biasing on the key top permitting the height of the key top to be lowered in response to the slidable displacement.
