Abstract
An ergonomic writing instrument has a writing section, a grasping section, and a stabilizing section. The writing instrument reduces stress and writing fatigue by providing the grasping section with a substantial thickness to keep users from clenching and a surface with a contour that essentially fits a portion of a hand, such as either the index finger or the middle finger of the left and right human hand or that essentially fits portions of both the index finger and middle finger. The grasping section is generally symmetrical about a plane essentially normal to the contoured surface so that the writing instrument can be used by either a right handed person or a left handed person.
Claims26
A writing instrument for use in either the right or left hand, said writing instrument having a generally elongated body comprising:
- a first end;
- a second end;
- a writing section disposed at said first end;
- and
- a grasping section disposed between said writing section and said second end, said grasping section comprising a first surface, a second surface, and a third surface, said first surface and said second surface lying generally in a first plane and a second plane respectively, said first and second planes intersecting one another about a plane of symmetry, and said third surface being generally perpendicular to and generally symmetrical about said plane of symmetry;
- wherein said third surface further has a longitudinal curved contour for fitting a part of a hand.
A writing instrument for use in either the right or left hand, said writing instrument having a generally elongated body comprising:
- a writing section;
- a stabilizing section;
- and
- a grasping section disposed between said writing section and said stabilizing section, said grasping section comprising a first surface, a second surface, and a third surface, said first surface and said second surface lying generally in a first plane and a second plane respectively, said first and second planes intersecting one another about a plane of symmetry, and said third surface being generally perpendicular to and generally symmetrical about said plane of symmetry;
- wherein said third surface further has a longitudinal contour for fitting a part of a hand;
- and
- wherein said stabilizing section comprises a fourth surface lying generally in a fourth plane and being generally perpendicular to and generally symmetrical about said plane of symmetry.
A writing instrument having a body that is generally elongated along a longitudinal axis, said writing instrument comprising:
- a writing section;
- a stabilizing section, said longitudinal axis passing through at least portions of said writing section and said stabilizing section;
- and
- a grasping section disposed between said writing section and said stabilizing section, said grasping section having a first surface, a second surface, and a third surface lying generally in a first plane, a second plane, and a third plane respectively, said first and second planes intersecting one another about a plane of symmetry, and said third plane intersecting the first and second planes and being perpendicular to said plane of symmetry and angled relative to said longitudinal axis to increase the thickness of said grasping section to keep a user from clenching the grasp of said writing instrument.
A writing instrument having a body that is generally elongated along a longitudinal axis, said writing instrument comprising:
- a writing section;
- a stabilizing section, said longitudinal axis passing through at least portions of said writing section and said stabilizing section;
- and
- a grasping section disposed between said writing section and said stabilizing section, said grasping section having a first surface, a second surface, and a third surface lying generally in a first plane, a second plane, and a third plane respectively, said first and second planes intersecting one another about a plane of symmetry, and said third plane intersecting the first and second planes and being perpendicular to said plane of symmetry and angled relative to said longitudinal axis;
- wherein the angle between said third plane and said longitudinal axis is different from the angle between said first plane and said longitudinal axis and the angle between said second plane and said longitudinal axis.
