ABSTRACT:
In an ergonomic keyboard comprising at least two housing sections with separate key pads wherein the two housing sections are interconnected by a joint permitting pivoting and also tilting of the two housing sections relative to each other, the joint comprises a coil spring which extends between, and is connected to, the two housing sections at the end of the housing sections remote from an operator so as to form a universal joint between the two housing sections, and a sector-shaped indexing plate is mounted with one end firmly to one of the housing sections and extends into the other housing section so that it bridges any gap formed between the two housing sections when they are pivoted apart, and the other housing section has a guide pin projecting into a partial circular guide slot formed in the indexing plate and having a center of curvature coinciding with the universal joint pivoting center for guiding the two housing sections relative to each other.
