Abstract

Power machine bucket implements include a rear wall structure, a bottom wall structure adjoining the rear wall structure at a bend region, and a two-piece brace. The two-piece brace includes a first piece attached to and extending along a portion of the bottom wall structure and a second piece, separate from the first piece, attached to the back side of the rear wall structure.

Claims (37)

1. A power machine bucket implement, comprising:

a rear wall structure;

a bottom wall structure adjoining the rear wall structure at a bend region;

an L-bracket secured to the bottom wall structure and to the rear wall structure at the bend region between the bottom wall structure and the rear wall structure;

a two-piece brace including a first piece attached to and extending along a portion of the bottom wall structure and a second piece, separate from the first piece, attached to and extending along a horizontal portion of the back side of the rear wall structure; and

an implement carrier attached to the back side of the rear wall structure, wherein the implement carrier interface includes first and second engagement portions providing first and second lip portions extending away from the back side of the rear wall structure, and wherein the second piece of the two-piece brace extends along the horizontal portion of the back side of the rear wall structure beneath the first and second lip portions of the implement carrier interface.

2. The implement of claim 1 , wherein the second piece of the two-piece brace extends horizontally along at least half of the back side of the rear wall structure.

3. The implement of claim 1 , wherein the first and second lip portions of the implement carrier interface are spaced apart, and wherein the second piece of the two-piece brace extends an entire width between the spaced apart first and second lip portions.

4. The implement of claim 3 , wherein the second piece of the two-piece brace extends from an outer edge of the first lip portion to an outer edge of the second lip portion.

5. The implement of claim 1 , wherein the second piece of the two-piece brace includes:

a tab portion configured to be received in a slot formed in the rear wall structure; and

horizontally extending portions extending laterally from the tab portion and configured to interface and be attached to the rear wall structure or the L-bracket, wherein the horizontally extending portions include first and second end portions configured to be attached to first and second lip portions of an implement carrier interface.

6. The implement of claim 1 , wherein the second piece of the two-piece brace is attached to the L-bracket secured to the bottom wall structure and to the rear wall structure at the bend region.

7. The implement of claim 1 , wherein the second piece of the two-piece brace is attached to back side of the rear wall structure through attachment to the L-bracket secured to the bottom wall structure and to the rear wall structure at the bend region.

8. A power machine bucket implement, comprising:

a rear wall structure;

a bottom wall structure adjoining the rear wall structure at a bend region;

a first side wall structure adjoining the rear wall structure at a first edge and adjoining the bottom wall structure at a second edge;

a second side wall structure adjoining the rear wall structure at a third edge and adjoining the bottom wall structure at a fourth edge;

an implement carrier interface attached to a back side of the rear wall structure and configured to mate with an implement carrier of a power machine, the implement carrier interface including first and second engagement portions providing first and second lip portions extending away from the back side of the rear wall structure;

a two-piece brace including a first piece attached to and extending along a portion of the bottom wall structure and a second piece, separate from the first piece, attached to the back side of the rear wall structure and to a bottom portion of the implement carrier interface, wherein the second piece of the two-piece brace includes horizontally extending portions configured to interface and be attached to the rear wall structure, wherein the horizontally extending portions include first and second end portions configured to be attached under first and second lip portions of the implement carrier interface.

9. The power machine bucket implement of claim 8 , and further comprising an L-bracket secured to the bottom wall structure and to the rear wall structure at the bend region between the bottom wall structure and the rear wall structure.

10. The implement of claim 9 , wherein the second piece of the two-piece brace extends along a horizontal portion of the back side of the rear wall structure beneath the first and second lip portions of the implement carrier interface.

11. The implement of claim 10 , wherein the first and second lip portions of the implement carrier interface are spaced apart, and wherein the second piece of the two-piece brace extends an entire width between the spaced apart first and second lip portions.

12. The implement of claim 11 , wherein the second piece of the two-piece brace extends from an outer edge of the first lip portion to an outer edge of the second lip portion.

13. The implement of claim 12 , wherein the second piece of the two-piece brace further includes:

a tab portion configured to be received in a slot formed in the rear wall structure; and

wherein the horizontally extending portions extend laterally from the tab portion.

14. A power machine bucket implement, comprising:

a rear wall structure;

a bottom wall structure adjoining the rear wall structure at a bend region;

a first side wall structure adjoining the rear wall structure at a first edge and adjoining the bottom wall structure at a second edge;

a second side wall structure adjoining the rear wall structure at a third edge and adjoining the bottom wall structure at a fourth edge;

an implement carrier interface attached to a back side of the rear wall structure and configured to mate with an implement carrier of a power machine, the implement carrier interface including first and second engagement portions providing first and second lip portions extending away from the back side of the rear wall structure;

a two-piece brace including a first portion attached to and extending along a portion of the bottom wall structure and a second portion attached to the back side of the rear wall structure and to a bottom portion of the implement carrier interface, wherein the second portion of the two-piece brace includes:

a tab portion configured to be received in a slot formed in the rear wall structure; and

horizontally extending portions extending laterally from the tab portion and configured to interface and be attached to the rear wall structure, wherein the horizontally extending portions include first and second end portions configured to be attached under first and second lip portions of the implement carrier interface.
