| 41 | Keyboard with full-travel, self-leveling keyswitches and return mechanism keyswitch | US227637 | 1994-04-14 | US5422447A | 1995-06-06 | Kenny R. Spence |
| An improved alphanumeric keyboard 10 is illustrated for use in lap top or notebook personal computers 12. The keyboard 10 has a plurality of full travel, self leveling keyswitches 14 for actuating printed circuit electrical contacts 22 and 26 when the keyswitch is depressed. The keyboard 10 includes an integral keyswitch structure 40 that has an integral keytop 42 and keytop support substructure 44 supported on a common integral base sheet 46. Each of the keytop support substructures 44 includes hinge members 50a50b, 50c and 50d that are positioned in a rectangular orientation about the keytop 42. Each hinge member has a rigid upper hinge panel 52 and a lower hinge panel 58 that are integrally interconnected to the keytop 42 and the base sheet 46 for maintaining the keytop in a parallelogram orientation as it is depressed to prevent the keytop from moving laterally or wobbling during depression. The hinge panels 52 and 58 are interconnected by resilient webs 54, 60 and 64. In one embodiment, the resilient webs return the keytop to its elevated non-actuating position. In the last-mentioned preferred embodiment, a leaf spring 208 is provided to urge the keytop back to its non-actuating rest position. | ||||||
