Abstract

A wear member configured to be attached to a work implement includes a body defining a front working region, a rear mounting region, a first side region connecting the front working region to the rear mounting region, and a second side region connecting the front working region to the rear mounting region. The rear mounting region includes a plurality of mounting pads and defines at least once recess disposed at least partially on at least one of the plurality of the mounting pads.

First claim

What is claimed is:

1. A wear member configured to be attached to a work implement, the wear member comprising:
a body defining a front working region, a rear mounting region, a bottom surface connecting the front working region to the rear mounting region, a first side region connecting the front working region to the rear mounting region, and a second side region connecting the front working region to the rear mounting region,
wherein the rear mounting region includes a plurality of mounting pads and defines at least one recess disposed at least partially on at least one of the plurality of the mounting pads, and the rear mounting region lacks a forked portion,
a plurality of mounting apertures extending completely through the body from the front working region to the rear mounting region, and that are disposed at least partially on at least one of the plurality of mounting pads, and each of the mounting pads includes a rear planar surface, and the front working region includes a front planar surface that forms an acute angle with the rear planar surface of each of the mounting pads;
at least a first shelf portion disposed underneath at least one of the mounting pads; and
two shelf portions, separated by a V-shaped notch, and the plurality of mounting pads extend rearward from the two shelf portions.

2. The wear member of claim 1 , wherein the mounting pad defines a rear planar face and the at least one recess is a first blind pocket disposed on the rear planar face adjacent at least one of the plurality of the mounting apertures that extends completely through the body.

3. The wear member of claim 2 , wherein at least one of the mounting pads includes an upper portion defining an upper perimeter, forming an upper pocket.

4. The wear member of claim 3 , wherein the upper perimeter at least partially forms a “W” configuration.

5. The wear member of claim 4 , wherein the body further defines a separating pocket disposed between each of the mounting pads.

6. The wear member of claim 2 , wherein the first blind pocket defines a trapezoidal perimeter.

7. A wear member configured to be attached to a work implement, the wear member comprising:
a body defining a front working region, a rear mounting region, a bottom surface connecting the front working region to the rear mounting region, a first side region connecting the front working region to the rear mounting region, and a second side region connecting the front working region to the rear mounting region;
wherein the rear mounting region includes a plurality of mounting pads and defines at least one recess disposed at least partially on at least one of the plurality of the mounting pads, and further includes two shelf portions, separated by a V-shaped notch, and the plurality of mounting pads extend rearward from the two shelf portions.

8. The wear member of claim 7 , wherein the two shelf portions extend to a level underneath the plurality of mounting pads.

9. The wear member of claim 7 , wherein the wear member defines a plurality of mounting apertures extending completely through the body from the front working region to the rear mounting region, and that are disposed at least partially on at least one of the plurality of mounting pads.

10. The wear member of claim 9 , wherein at least one of the plurality of mounting pads defines a rear planar face and the at least one recess is a first blind pocket disposed on the rear planar face adjacent at least one of the plurality of the mounting apertures that extends completely through the body.

11. The wear member of claim 9 , wherein at least one of the plurality of mounting pads includes an upper portion defining an upper perimeter, forming an upper pocket.

12. The wear member of claim 11 , wherein the upper perimeter at least partially forms a “W” configuration.

13. The wear member of claim 12 , wherein the body further defines a separating pocket disposed between each of the plurality of mounting pads.

14. The wear member of claim 10 , wherein the first blind pocket defines a trapezoidal perimeter.
