Abstract
A fulcrum prybar includes a shaft portion extending along a first axis, a curved prying portion affixed to a first end of the shaft portion, and a fulcrum portion affixed to the curved prying portion. The fulcrum portion includes two rectangular portions fused together to form an obtuse angle or a right angle cross section. One of the two rectangular portions is oriented such that it is flush with a horizontal surface while the prybar has partially raised an object from the same or another horizontal surface.
Claims19
A prybar, comprising:
- a shaft portion extending along a first axis;
- a prying portion affixed to a first end of the shaft portion, wherein the prying portion curves away from the first axis and toward a third axis, wherein the third axis is perpendicular to the first axis;
- a fulcrum portion affixed to the prying portion, wherein the fulcrum portion comprises:
- a first rectangular portion;
- and
- a second rectangular portion,
- wherein a first edge of the first rectangular portion is affixed to a second edge of the second rectangular portion, wherein the first edge is affixed to the second edge such that a cross section of the first and second rectangular portions forms an obtuse or right angle,
- wherein a third edge of the first rectangular portion opposite the first edge is affixed to the prying portion at a first location,
- wherein a fourth edge of the second rectangular portion opposite the second edge is affixed to the prying portion at a second location, wherein the first location is closer to a distal end of the prying portion than the second location,
- wherein the fulcrum portion is affixed to the prying portion such that a triangular cavity is formed between the fulcrum portion and the prying portion, and
- wherein the first and second rectangular portions extend along a second axis farther than the prying portion extends along the second axis, wherein the second axis is perpendicular to the first axis and the third axis, and wherein the first, second, third and fourth edges are oriented along the second axis.
