Abstract
A tool, such as a pry bar including a textured tip is shown. In one embodiment, the textured tip includes a plurality of projections and a plurality of grooves. Various textured tip embodiments are configured to increase friction/gripping with a workpiece, thereby increasing a pry force applied to the workpiece before the pry bar slips and/or loses contact with the workpiece.
Claims20
A pry bar comprising:
- a handle;
- a shaft extending along a longitudinal axis of the pry bar;
- and
- an engagement end extending from the shaft, the engagement end comprising:
- a tip surface;
- and
- a textured surface section positioned on the tip surface, the textured surface section comprising:
- a plurality of protrusions, wherein each protrusion includes a plurality of edges that together define a raised upper surface of the protrusion;
- and
- a plurality of grooves, wherein each groove extends along at least one of the plurality of protrusions;
- wherein a length of the pry bar is defined between a distal end of the handle and a front edge of the engagement end;
- wherein a length of the textured surface section is defined between the front edge of the engagement end and a rear edge of the textured surface section;
- and
- wherein a ratio of the length of the pry bar to the length of the textured surface section is between 9 and 14.

A pry bar comprising:
- a shaft;
- and
- a tip extending from the shaft, the tip comprising:
- a tip surface;
- a first front edge extending along the tip surface;
- a second front edge spaced from the first front edge;
- and
- a textured surface section positioned on the tip surface, the textured surface section comprising:
- a protrusion comprising a raised surface;
- and
- a groove extending along at least one edge of the protrusion, the groove comprising a bottom point;
- wherein a height of the protrusion is defined between the raised surface of the protrusion and the bottom point of the groove;
- and
- wherein a thickness of the textured surface section is defined between the second front edge and the raised surface, and wherein a ratio of the height of the protrusion to the thickness is greater than 0.1.
11 more elements
A pry bar comprising:
- a handle comprising a distal end;
- a shaft coupled to and extending from the handle along a longitudinal axis of the pry bar;
- and
- a tip extending from the shaft, the tip comprising:
- a tip surface;
- and
- a textured surface section positioned on the tip surface and extending along the longitudinal axis, the textured surface section comprising:
- a plurality of protrusions, wherein each of the protrusions includes a plurality of edges that together define a raised surface of the protrusion, the raised surface defining an area;
- and
- a groove extending along at least one of the plurality of protrusions;
- wherein a length of the pry bar is defined between the distal end of the handle and a front edge of the tip, and wherein a ratio of the length of the pry bar to the area is greater than 150.
