Abstract

A support member for use with a support assembly for ground engaging tools comprises a structural member; and a resilient member that includes a base, and a contact surface, and wherein the structural member defines a direction of assembly and the resilient member defines a length and a width that are perpendicular to each other and to the direction of assembly, wherein the length exceeds the width and the base defines a centerline that is parallel to the length, and the contact face defines a centerline that is parallel to the length.

First claim

What is claimed is:

1. A shroud insert assembly for use with a support assembly for ground engaging tools, the shroud insert assembly comprising:
a shroud insert comprising:
a throat portion that defines a recess that defines a longitudinal axis and a direction of assembly for the shroud insert that are coextensive;
a front and a rear disposed along the direction of assembly;
a first upper leg;
a first lower leg; and
a first support portion that includes a support surface that defines a surface normal pointing toward the front of the shroud insert along the direction of assembly that forms an oblique angle with the direction of assembly; and

a support member that is attached to the support surface comprising:
a resilient member.

2. The shroud insert assembly of claim 1 wherein the resilient member includes at least one of the following: a rubber, a polyurethane, a closed-cell foam, and a spring.

3. A shroud insert for use with a support assembly for ground engaging tools, the shroud insert comprising:
a throat portion that defines a recess that defines a longitudinal axis and a direction of assembly for the shroud insert that are coextensive;
a front and a rear disposed along the direction of assembly;
a first upper leg;
a first lower leg; and
a first support portion that includes a support surface that defines a surface normal pointing toward the front of the shroud insert along the direction of assembly that forms an oblique angle with the direction of assembly; and
wherein the throat portion includes a curved configuration that defines a lateral direction and the recess is an inner recess that is centered laterally along the lateral direction and the throat portion further defines an outer recess that is positioned between the support portion and the center recess along the lateral direction.

4. The shroud insert of claim 3 , wherein at least a portion of the support surface is positioned forward of the throat portion along the direction of assembly and the legs extend from the throat portion in a rearward direction along the direction of assembly.

5. The shroud insert of claim 3 , wherein the oblique angle ranges from 110-160 degrees.

6. The shroud insert of claim 3 further comprising:
a second upper leg; and
a second lower leg;
wherein the first upper leg and second upper leg define a pathway for the insertion of a portion of a shroud protector and the first lower leg and second lower leg define another pathway for the insertion of a portion of a shroud protector.

7. The shroud insert of claim 6 , wherein the legs each include a curved surface that is configured to match the contour of a working edge of a work implement.

8. The shroud insert of claim 7 , wherein the legs each further includes an angled surface that is adjacent the curved surface.

9. The shroud insert of claim 3 further comprising a second support portion that includes a support surface that defines a surface normal pointing toward the front of the shroud insert along the direction of assembly that forms an oblique angle with the direction of assembly.

10. The shroud insert of claim 9 , wherein the first support portion is more forward of the throat portion along the direction of assembly than the second support portion.

11. The shroud insert of claim 3 , wherein the support surface defines at least one pocket.

12. The shroud insert of claim 11 , wherein the pocket is completely bound by the support surface and includes a trapezoidal configuration.

13. The shroud insert of claim 11 , wherein the pocket is adjacent an edge of the support surface and includes a rectangular configuration.

14. The shroud insert of claim 13 , wherein the pocket defines a pry slot adjacent the pocket, the pry slot having a different depth than the pocket.
