Abstract
An ergonomically adjustable sit/stand keyboard arm apparatus is disclosed. The apparatus is slidably mounted on the underside of a work surface such as a table. A first rotatable housing depends from the sliding mount. The first housing is connected to a second housing by a parallel linkage means. A keyboard platform is rotatably mounted on the second housing. An extender is provided between the second housing and the keyboard platform to raise the keyboard platform to sufficient height for use by the operator while standing and to permit the arm to be lowered below a generally horizontal orientation. The keyboard platform is maintained in position by a self-locking pneumatic cylinder and an adjustable cylinder assembly for counterbalancing the load on the parallel linkage mechanism.
