Abstract: The invention relates to an adjustable keyboard to be used, for example, at a computer terminal (12). The preferred embodiment is in the form of a keyboard having a number of keys (5), the keyboard being formed in at least two segments (2, 3) which are mutually movable relative- to one another using a hinge or joint (6). Each of the segments (2, 3) of the keyboard has mounted thereon some of the keys (5). The relatively movable nature of the keyboard aims at reducing stress and discomfort to the user by eliminating contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint (6) may be in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle (100), in the form of a lever, used for locking and unlocking the hinge or joint (6).
