Abstract

This article describes a keyboard which is adjustable to different angular positions. A keyboard includes a base plate formed of portions 1 and 2 pivotally connected to each other by a molded-in hinge 3 so that the portion 2 is pivotable relative to the portion 1 about an axis 4 (Fig. 3). The base plate is molded of a thermoplastic material so as to be bendable with the hinge 3 having a reduced thickness in comparison with the portions 1 and 2. A bail 5 (Fig. 1) has its opposite ends supported in bosses 6 (one shown), which are supported on the portion 1 of the base plate. The portion 2 of the base plate has keys 7 supported thereby for activating membrane switches (not shown), for example. The bail 5 is positioned in a longitudinal slot 8 in the bottom of a downwardly projecting portion 9 of a position adjustment slide 10.

Keyboard Adjustment Mechanism Utilizing an Integral Molded-In Hinge

This article describes a keyboard which is adjustable to different angular positions. A keyboard includes a base plate formed of portions 1 and 2 pivotally connected to each other by a molded-in hinge 3 so that the portion 2 is pivotable relative to the portion 1 about an axis 4 (Fig. 3). The base plate is molded of a thermoplastic material so as to be bendable with the hinge 3 having a reduced thickness in comparison with the portions 1 and 2. A bail 5 (Fig. 1) has its opposite ends supported in bosses 6 (one shown), which are supported on the portion 1 of the base plate. The portion 2 of the base plate has keys 7 supported thereby for activating membrane switches (not shown), for example. The bail 5 is positioned in a longitudinal slot 8 in the bottom of a downwardly projecting portion 9 of a position adjustment slide 10. The slide 10 is movable in slots 11 in a cover 12 between the positions of Figs. 1 and 2 and is held in either position since the bail 5 is in an over-center position in either position. The position of the keys 7 in Fig. 1 is the normal keyboard position, while the position of the keys 7 in Fig. 2 is that of an elevated position of the keyboard.
