A computer workstation for supporting and positioning a computer and/or its video display terminal and its keyboard at optimal ergonometric position with respect to the arms, wrists, fingers, eyes and posture of the user. Keyboard is supported on a keyboard shelf having depending side members from which arm and foot members extend. The workstation has side panels providing leg members on which are racks having two rows of vertically spaced slots. The row of slots nearest the keyboard shelf receive the tips of the side member-mounted arms which can be hooked and captured in channels in the slots in which they are received. The assembly forms a mechanical couple which, under the force of gravity, rotates about the arm member's tips until the foot member bears against an edge presented by the rack. An arm rest extends laterally across the shelf and is attached to the side members of the shelf assembly for translational and rotational motion so as to position the arm and wrist of the user with respect to the keyboard. A terminal may be located on a table behind the keyboard shelf. Within the front edge of the table nearest and facing the user is a transverse pivot rod whose ends extend beyond the sides of the table. The ends of the pivoting rod enter slots in the other row of slots farthest from the keyboard shelf. The opposite end of the table is supported by a belt. A screw feed mechanism lengthens and shortens the belt so as to select the inclination of the table by enabling the table to rotate about the axis of the rod.
In a workstation having a table for supporting a computer display terminal with a screen facing a user, said table being mounted on vertically extending leg members, a shelf assembly on which a keyboard can be disposed in ergonomically optimal relationship with the user's arm, wrist and fingers, said assembly comprising a shelf, side members depending from said shelf, said side members having rear and forward ends respectively facing away from and towards said table, arm and foot members projecting forwardly, from each of said rear ends, said arm members being above said foot members, racks along said leg members, said racks having pluralities of vertically spaced slots in which said arms are selectively captured to locate said shelf at different elevations and to define pivots for said assembly, said racks having forwardly facing edges against which said foot members bear, said assembly being releaseably retained by said racks, and said arm and foot members defining mechanical couples enabling said assembly to rotate about said pivots under the force of gravity until stopped by said forwardly facing edges of said racks upon engagement thereof by said foot members, a bar providing a rest for the user' s wrist or arm, said bar extending laterally along said shelf, laterally spaced brackets supporting said rest and projecting forwardly along said side members, and means for connecting said brackets to said side members and enabling movement of said rest forwardly and rearwardly in translation and rotationally in upward and downward directions to selected positions with respect to said shelf.
In a workstation for supporting a computer display terminal on a table located between laterally spaced leg members on which racks having a plurality of vertically spaced slots are disposed, said table having opposite ends extending laterally between said leg members, a mechanism for adjusting the elevation and inclination of said table which comprises at least one rod connected to said table along one of said opposite ends and having projection received in different ones of said second pluralities of slots for pivotally supporting said table at selected elevations, a belt extending across the other of said opposite ends of said table in supporting relationship to said table, a belt length varying mechanism for increasing and decreasing the length of said belt for pivoting said table about said rod to adjust the inclination thereof, which mechanism comprises a threaded rod mounted to said table for rotation about an axis extending between said opposite ends of said table, a nut on said threaded rod movable along said axis as said threaded rod rotates, a pulley journaled on said nut and movable therewith, said belt being fixed to said table at an end of said belt and extending around said pulley, and means for rotating said rod to move said pulley along said axis for shortening and lengthening said belt thereby changing the inclination of said table.
In a workstation having a table for supporting a computer display terminal with a screen facing a user, said table being mounted on vertically extending leg members, a shelf assembly on which a keyboard can be disposed in ergonomically optimal relationship with the user's arm, wrist and fingers, said assembly comprising a shelf, side members depending from said shelf, said side members having rear and forward ends respectively facing away from and towards said table, arm and foot members projecting forwardly from each of said ends, said arm members being above said foot members, racks along said leg members, said racks having pluralities of vertically spaced slots in which said arms are selectively captured to locate said shelf at different vertical heights and to define pivots for said assembly, said assembly being releaseably retained by said racks, and said arm and foot members defining mechanical couples enabling said assembly to rotate about said pivots under the force of gravity until stopped by said racks upon engagement thereof by said foot members.
