  • Patent number: 5452876
    Abstract: A copy holder which may be placed in-line vertically with a computer monitor to reduce visual fatigue and head turning. A rear edge portion of the copy holder tray is attached to fasteners which are mounted in elongate slots in the side walls for movement of the copy holder tray between a first position within the copy holder for storage of copy and a second position wherein the copy holder tray extends forwardly from the copy holder for displaying copy. The slots are elevated above a desktop so that the copy holder tray is inclined to the desktop at a comfortable predetermined angle, preferably about 22 degrees, when in the second position, with the monitor screen elevated to a comfortable viewing height. In accordance with one embodiment, the copy holder is caused to be received or rest on the shelf of a monitor stand to achieve the predetermined angle. Alternatively, the side walls of the copy holder extend to a height which achieves the predetermined angle.

  • Patent number: 5386956
    Abstract: 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.
