Abstract
A base edge includes a plurality of center notches and a first and a second end notches that all include the same configuration, defining a notch depth along direction of assembly, a straight middle portion straddled laterally by a first arcuate corner portion and a second arcuate corner portion, the straight middle portion defining a lateral straight middle portion width, and the notch depth ranges from 0.1 multiplied by the lateral straight middle portion width to 0.5 multiplied by the lateral straight middle portion width.
Claims20
A base edge comprising:
- a body including a working edge defining a lateral direction and a direction of assembly perpendicular to the lateral direction, the body further defining
- a first lateral end and a second lateral end;
- a plurality of vertical mounting mechanism receiving apertures;
- a plurality of center notches extending from the working edge;
- and
- a first end notch disposed proximate to the first lateral end and a second end notch disposed proximate to the second lateral end, the first end notch and the second end notch extending from the working edge;
- wherein each of the plurality of center notches and the first and the second end notches includes the same configuration, defining a notch depth along direction of assembly, each of the plurality of center notches and the first and the second end notches further includes a straight middle portion straddled laterally by a first arcuate corner portion and a second arcuate corner portion, the straight middle portion defining a lateral straight middle portion width, and the notch depth ranges from 0.1 multiplied by the lateral straight middle portion width to 0.5 multiplied by the lateral straight middle portion width such that the lateral straight middle portion, the first arcuate corner portion, and the second arcuate corner portion provide an anti-rotational bearing surface.
An adapter comprising:
- a body that includes:
- a nose portion that is configured to facilitate the attachment of a tool;
- a first leg;
- a second leg;
- a throat portion that connects the legs and nose portion together;
- at least one of the first leg and the second leg defines an aperture that is configured to receive a mounting mechanism;
- and
- the first and the second legs and the throat portion define a slot that includes a closed end and an open end, the slot defining a direction of assembly onto a work implement and a lateral direction that is perpendicular to the direction of assembly, and the throat portion further comprises a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction, and the throat portion further comprises a protrusion disposed at the closed end of the slot, the protrusion extending along the direction of assembly and along the lateral direction proximate to the first throat side surface and proximate to the second throat side surface;
- and
- wherein the protrusion defines a protrusion height along the direction of assembly, the protrusion further includes a flat middle portion straddled laterally by a first arcuate portion and a second arcuate portion, the flat middle portion defining a middle lateral width, and the protrusion height ranges from 0.1 multiplied by the middle lateral width to 0.5 multiplied by the middle lateral width such that the flat middle portion, the first arcuate portion, and the second arcuate portion provide an anti-rotational bearing surface.
A work implement assembly comprising:
- a notched base edge defining a notch, a first lateral end, and a second lateral end;
- an adapter attached to the notched base edge, the adapter including
- a body that includes:
- a nose portion that is configured to facilitate the attachment of a tool;
- a first leg;
- a second leg;
- a throat portion that connects the legs and nose portion together;
- at least one of the first leg and the second leg defines an aperture that is configured to receive a mounting mechanism;
- and
- the first and the second legs and the throat portion define a slot that includes a closed end and an open end, the slot defining a direction of assembly onto a work implement and a lateral direction that is perpendicular to the direction of assembly, and the throat portion further comprises a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction, and the throat portion further comprises a protrusion disposed at the closed end of the slot, the protrusion extending along the direction of assembly and along the lateral direction proximate to the first throat side surface and proximate to the second throat side surface;
- and
- wherein the protrusion defines a protrusion height along the direction of assembly, the protrusion further includes a flat middle portion straddled laterally by a first arcuate portion and a second arcuate portion, the flat middle portion defining a middle lateral width, and the protrusion height ranges from 0.1 multiplied by the middle lateral width to 0.5 multiplied by the middle lateral width such that the flat middle portion, the first arcuate, and the second arcuate portion provide maximized contact surface.
