Abstract
An ergonomic hand grip for a hand operated tool has a pair of spaced apart curvilinear side beams having first ends and second ends, the first ends being coupled to each other; a forearm brace coupling the second ends of the side beams to each other, the forearm brace extending in a direction from the second ends toward the first ends, and only on one side of the side beams; and a gripping member mounted between the side beams, the gripping member being neither parallel to nor perpendicular to said side beams. The gripping member acts as a flat spring and the side beams act as a pair of torsion springs.
Claims25
A hand operated tool, comprising:
- a) a pair of spaced apart side beams having first ends and second ends, said first ends being coupled to each other;
- b) a forearm brace coupling said second ends of said side beams to each other, said forearm brace extending in a direction from said second ends toward said first ends, and on only one side of said side beams;
- and
- c) a gripping member mounted between said side beams, said gripping member extending downward from said first ends of said side beams and being neither parallel to nor perpendicular to said side beams.
A hand operated tool, comprising:
- a) a pair of spaced apart side beams having first ends and second ends, said first ends being coupled to each other;
