ABSTRACT:
A device for supporting the wrists of a keyboard operator or typist. The device includes a support member for supporting the operator's wrists, a mounting bracket adapted to be mounted on a base, a pair of connecting members respectively extending from the mounting bracket and the wrist support member, each of the connecting members having a slot disposed therein, and a pin extending parallel to the support member through each of the slots in the connecting member so as to respectively connect the pair of connecting members extending from the mounting bracket to the pair of connecting members extending from the wrist support member. In this manner, the wrist support member is pivotably adjustable relative to the mounting bracket about an axis which is disposed parallel to the mounting bracket, and the wrist support member is translatably adjustable in two directions angularly disposed with respect to one another. Therefore, the wrist support members are independently adjustable in three directions providing the operator with a large degree of adjustability.
