    摘要: 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).

    摘要: An adjustable support for a data input device and the like including a base attached to an associated worksurface, a platform shaped to support the data input device thereon and having a front portion and a rearward portion, and a support arm having one end pivotally joined with the base, and an opposite end pivotally joined to the rearward portion of the platform. Also included is a locking member fixed to the support arm, and an elongate brake element wrapped around the locking member, and having one end coupled to the base and a second end connected with the platform at a point spaced from the opposite end of the arm such that rotation of the tray about the coupling at the second end of the support arm releases the brake element and permits changes in the elevation of the support with respect to the base, and the moment of the platform and any associated input device tenses the braking element against the locking member and locks the platform in its selected position.
