Abstract

A keyboard, mouse, and wrist support arrangement with a pivotable transverse member, first and second elongate rails in combination with slide rails for slidably receiving the first and second elongate rails for retaining the pivotable transverse member for extension and retraction and for pivoting about a lateral pivot axis, a keyboard support plate retained relative to the pivotable transverse member, and a keyboard wrist support retained relative to the keyboard support plate. A mouse support plate, which can be independently moveable in relation to the keyboard support plate, can be retained relative to the pivotable transverse member, and a mouse wrist support retained relative to the mouse support plate.

8. The support arrangement of claim 6 wherein the means for retaining the first and second arms for extension and retraction comprises a means for slidably retaining a central portion of the transverse stabilizing member.

9. The support arrangement of claim 4 further comprising a protective storage compartment that enshrouds the first arm, the second arm, the transverse support member, and the keyboard support portion when the first arm, the second arm, the transverse support member, and the keyboard support portion are in a retracted position.

10. A support arrangement comprising:

a first arm with a proximal end and a distal end;

a second arm with a proximal end and a distal end;

means for pivotally retaining the proximal end of the first arm;

means for pivotally retaining the proximal end of the second arm;

means for retaining the first and second arms for extension and retraction;

a transverse support member with a first end coupled to the distal end of the first arm and a second end coupled to the distal end of the second arm wherein the first end of the transverse support member has a flange that pivotally engages the distal end of the first arm and wherein the second end of the transverse support member has a flange that pivotally engages the distal end of the second arm; and

a keyboard support portion retained relative to the transverse support member wherein the keyboard support portion is pivotable about a lateral pivot axis relative to the distal ends of the first and second arms whereby the keyboard support portion can be pivoted to a negative tilt through an angle α and

a positive tilt through an angle β

.

11. The support arrangement of claim 10 further comprising angular position markings disposed to indicate an angular position of the first and second arms.

12. The support arrangement of claim 10 wherein the keyboard support portion retained relative to the transverse support member comprises a portion of the transverse support member.

13. The support arrangement of claim 10 further comprising a segmented document holder and a means for slidably supporting the segmented document holder.

14. The support arrangement of claim 13 further comprising a means for selectively locking the first arm, the second arm, the transverse support member, and the keyboard support portion in the retracted position.

15. A support arrangement comprising:

a first arm with a proximal end and a distal end;

a second arm with a proximal end and a distal end;

means for pivotally retaining the proximal end of the first arm;

means for pivotally retaining the proximal end of the second arm;
