Abstract
A wrist rest for a keyboard, such as for computers, that can be adjusted vertically in height and in inclination independently of each other.
Claims9
A wrist rest comprising:
- a. a platform having a top surface, a bottom surface and two ends;
- b. a first cup extending downward from the first end and having grooves on its outer perimeter;
- c. a second cup extending downward from the second end and having grooves on its outer perimeter;
- d. a first rotatable cylinder with an open top and having grooves on its inner perimeter to rotatably cooperate with the grooves on the first cup to vertically adjust the first end of the platform;
- and
- e. a second rotatable cylinder with an open top and having grooves on its inner perimeter to rotatably cooperate with the grooves on the second cup to vertically adjust the second end of the platform.

A wrist rest comprising:
- a. a platform having a top surface, a bottom surface and two ends;
- b. a first cup extending downward from the first end and having grooves on its outer perimeter and a convex top with a slot;
- c. a second cup extending downward from the second end and having grooves on its outer perimeter and a convex top with a slot;
- d. a first rotatable cylinder with an open top and having grooves on its inner perimeter to rotatably cooperate with the grooves on the first cup to vertically adjust the first end of the platform;
- e. a second rotatable cylinder with an open top and having grooves on its inner perimeter to rotatably cooperate with the grooves on the second cup to vertically adjust the second end of the platform;
- and,
- f. a first and a second locking mechanism that cooperates with the first and second cup, respectively, such that the inclination of the platform relative to a horizontal plane can be adjusted.

A wrist rest comprising:
- a. a platform having a top surface, a bottom surface, a first end, and a second end;
- b. a first height adjusting mechanism cooperating with the first end to adjust the vertical height of the first end of the platform independently of the second end;
- c. a first tilt adjusting mechanism cooperating with a locking mechanism to adjust an inclination of the first end of the platform relative to a horizontal plane independently of the second end and independently of the height adjustment of the first end:
- d. a second height adjusting mechanism cooperating with the second end to adjust the vertical height of the second end of the platform independently of the first end;
- and,
- e. a second tilt adjusting mechanism cooperating with a locking mechanism to adjust an inclination of the second end of the platform relative to a horizontal plane independently of the first end and independently of the height adjustment of the second end.
