Abstract
A large area button in an electrical keyboard is prevented from jamming by being stabilized against tilt which results from depressive forces being applied remotely from the center of the button, the stabilization being achieved by the provision of two anti-roll bars attaching the button to the body of the keyboard and each preventing deviation of one of two axes of the button from being orthogonal both to one another and to the direction of depression of the button.
Claims7
A keyboard with depressable keys mounted on a base, the keyboard having apparatus for stabilizing the movement of the keys along the axes orthogonal to the direction of depression of the keys comprising:
- one or more rigid members, each said member movably secured at multiple points to said key and movably secured at multiple points to said base, said multiple securing points for said key and said base being along lines maintaining a parallel relation with one of said axis orthogonal to the direction of key depression, said secured rigid members stabilizing movement of said keys along the axes.
