Abstract
Abstract The invention is an apparatus for supporting the hand which includes a mounting element detachably attachable to a base. The shaft element is rotatably mounted to the mounting element by a pivot part and a hand support is rotatably attached to the shaft element. The shaft element includes two generally parallel regulation arms spaced distance from each other which are attached at one end to the pivot part and at the other end to a support side pivot part. The hand support is adjustable in height by moving the regulation arms in relation to the mounting element.
