Wrist rest for keyboard
First Claim
1. An improved wrist resting apparatus comprising in combination:
- a support rail that is elongated along an axis of elongation comprising a substantially planar bottom surface defining a first plane that is parallel to said axis of elongation; and
a support surface lying above said first plane, said support surface being characterized by a curvilinear shape, in cross sections perpendicular to said axis of elongation, having forward and rearward nodes with a palm depression lying therebetween so as to define a second plane that is tangential to both said forward and rearward nodes and intersects said first plane at an intersection angle in the range of ten degrees to twenty degrees.

Abstract
An improved wrist rest for use when typing on a typical computer keyboard for reducing the severity of symptoms of hand and wrist repetitive stress ailments such as carpal tunnel syndrome is disclosed. The apparatus includes a rectilinear keyboard support base to which a wrist supporting rail is secured. Cross sections perpendicular to the axis of elongation of the rail have a geometry that includes forward and rearward nodes with a palm depression lying therebetween for supporting the hypothenars of the user'"'"'s hands. A plane tangential to both forward and rearward nodes of the support rail intersects the plane of the keyboard support surface at a predetermined angle that is equal to the angle of the keyboard'"'"'s key plane with respect to the horizontal when same is placed on a horizontal work surface.

23. An improved wrist resting apparatus for use with a keyboard having at least one array of keys defining a key plane that intersects a horizontal plane at a predetermined non-zero key plane angle when said keyboard rests on a horizontal surface, comprising in combination:
-
a support rail that is elongated along an axis of elongation comprising a substantially planar bottom surface defining a first plane that is parallel to said axis of elongation; and a support surface lying above said first plane, said support surface being characterized by a curvilinear shape, in cross sections perpendicular to said axis of elongation, having forward and rearward nodes with a palm depression lying therebetween so as to define a second plane that is tangential to both said forward and rearward nodes and intersects said first plane at an intersection angle that is substantially equal to said predetermined key plane angle.

24. An improved wrist resting apparatus for use with a keyboard having a leading edge and at least one array of keys defining a key plane that intersects a horizontal plane at a predetermined non-zero key plane angle when said keyboard rests on a horizontal surface, comprising in combination:
-
a support rail that is elongated along an axis of elongation comprising a substantially planar bottom surface defining a first plane that is parallel to said axis of elongation; and a support surface lying above said first plane, said support surface being characterized by a curvilinear shape, in cross sections perpendicular to said axis of elongation, having forward and rearward nodes with a palm depression lying therebetween and a forward wall adjacent to said forward node, said forward and rearward nodes defining a second plane that is tangential to both said forward and rearward nodes and intersects said first plane at an intersection angle that is substantially equal to said predetermined key plane angle and said second plane is substantially co-planar with said key plane when said leading edge of said keyboard is in abutment with said forward wall of said support surface.
