Adjustable wrist support for use with office machines having a keyboard

A wrist support device (10) that is positioned in front of a computer keyboard, typewriter or the like to support a typist's hands at the keyboard, is described. The wrist support device comprises a pair of blocks (12, 14) having similar rectangular shapes along a longitudinal axis A-A of the device and that pivotally support an intermediate support tray (16) holding an associated wrist rest (18). The longitudinal axis is spaced from and parallel with a rotation axis B-B provided by a pair of bolts (62, 76) connecting between the support tray and the support blocks. This provides for adjusting the tilt angle of the wrist support by rotating the support tray and wrist support about the rotation axis. In addition, the off-center rotation axis provides for adjusting the vertical height of the wrist support above a support surface (48) by positioning the support blocks on the support surface on any one of their corresponding similar sides.
