Abstract
A computer display includes a pivotally mounted upper housing having a display screen, a brake used to retard pivoting motion of this upper housing, and a release mechanism for releasing the brake so that the upper housing can be freely moved. The display screen is preferably a touchscreen, which is touched to indicate a selection made by the user, with the brake resisting a tilting movement of the screen as it is touched. In a first version, two brakes are used to retard motion in both directions, with a single release wheel being turned in one direction to allow rearward motion of the upper housing and in another direction to allow forward motion of the upper housing. In a second version, a single brake is released by stopping motion of a release mandrel to unwrap a clutch spring. In a third version, two brakes, operating near opposite edges of the upper housing to stop downward movement of the upper housing, provide a particularly stiff mechanism for mounting the upper housing, and are simultaneously released by turning a knob to pivot a shaft.
