Abstract

Disclosed embodiments include backscreens, backscreen accessories for implements of power machines, and implements including the same. In the backscreens or backscreen accessories, a first backscreen portion is attached to a frame of the implement, for example by welding. The first backscreen portion includes at least one first portion interface feature. A second backscreen portion has at least one second portion interface feature. The at least one first portion interface feature and the at least one second portion interface feature are configured to engage one another to removably couple the second backscreen portion to the first backscreen portion.

First claim

What is claimed is:

1. A backscreen accessory for an implement of a power machine, the implement having a frame with a first side and a second side, the accessory comprising:
a first backscreen portion having a first end attached to the frame of the implement and a second end attached to the frame of the implement, the first backscreen portion having at least one first portion interface feature; and
a second backscreen portion having at least one second portion interface feature, wherein the at least one first portion interface feature and the at least one second portion interface feature are configured to engage to removably couple the second backscreen portion to the first backscreen portion such that the second backscreen portion extends toward the second side of the frame in a direction away from both of the first and second ends of the first backscreen portion in a laterally offset position with respect to the first backscreen portion.

2. The backscreen accessory of claim 1 , wherein the at least one first portion interface feature and the at least one second portion interface feature are configured to engage to removably couple the second backscreen portion to the first backscreen portion at a position adjacent a side of the first backscreen portion.

3. The backscreen accessory of claim 2 , wherein the at least one second portion interface feature includes a first second portion interface feature, and wherein the at least one first portion interface feature and the first second portion interface feature are configured to engage to removably couple the second backscreen portion to the first backscreen portion, and further comprising a third backscreen portion configured to be attached to the frame of the implement, wherein the at least one first portion interface feature and the first second portion interface feature are configured to engage to removably couple the second backscreen portion to the first backscreen portion at a position between the first and third backscreen portions.

4. The backscreen accessory of claim 3 , wherein the third backscreen portion includes at least one third portion interface feature, wherein the at least one second portion interface feature includes a second second portion interface feature, and wherein the second second portion interface feature and the at least one third portion interface feature are configured to engage to removably couple the second backscreen portion to the third backscreen portion.

5. The backscreen accessory of claim 2 , wherein when the second backscreen portion is removably secured to the first backscreen portion, top surfaces of both of the first and second backscreen portions extend to substantially a same height relative to the implement.

6. The backscreen assembly of claim 2 , wherein the at least one first portion interface feature and the at least one second portion interface feature are configured to engage to removably couple the second backscreen portion to the first backscreen portion at a position which is both adjacent the side of the first backscreen portion and above the first backscreen portion.

7. The backscreen assembly of claim 1 , wherein the first backscreen portion is welded to the frame of the implement.

8. The backscreen assembly of claim 1 , wherein one of the at least one first portion interface feature and the at least one second portion interface feature includes a slot, and the other of the at least one first portion interface feature and the at least one second portion interface feature includes a tab configured to be received in the slot.

9. The backscreen assembly of claim 1 , wherein the first and second backscreen portions include a plurality of vertically oriented members.

10. The backscreen assembly of claim 1 , wherein the first and second backscreen portions include screens.

11. The backscreen accessory of claim 1 , wherein when the at least one first portion interface feature and the at least one second portion interface feature are engaged to removably couple the second backscreen portion to the first backscreen portion, the first backscreen portion extends toward the first side of the frame in a direction away from both of the second backscreen portion and the second end of the first backscreen portion.

12. An implement comprising:
an implement interface configured to removably mount the implement to a power machine interface;
a tool having a frame secured to the implement interface, the frame having a first side and a second side; and
a modular backscreen attached to one of the implement interface and the tool, the modular backscreen comprising:
a first backscreen portion having a first end attached to the one of the implement interface and the tool and having a second end attached to the one of the implement interface and the tool, the first backscreen portion including a first portion interface feature; and
a second backscreen portion having a first second portion interface feature, wherein the first portion interface feature and the first second portion interface feature are configured to engage to removably couple the second backscreen portion to the first backscreen portion such that the second backscreen portion extends in a first direction toward the second side of the frame and away from both of the first and second ends of the first backscreen portion in a laterally offset position with respect to the first backscreen portion.

13. The implement of claim 12 , and further comprising a third backscreen portion attached to the one of the implement interface and the tool, the third backscreen portion including a third portion interface feature, wherein a second second portion interface feature of the second backscreen portion and the third portion interface feature are configured to engage to removably couple the second backscreen portion also to the third backscreen portion at a position at least partially between the first and third backscreen portions.

14. The implement of claim 13 , wherein when the second backscreen portion is removably secured to the first and third backscreen portions, top surfaces of all of the first, second and third backscreen portions extend to substantially a same height relative to the one of the implement interface and the tool.

15. The implement of claim 13 , wherein when the second backscreen portion is removably secured to the first and third backscreen portions, the second backscreen portion is positioned both between and above the first and third backscreen portions.

16. The implement of claim 13 , wherein the first and third backscreen portions are welded to the one of the implement interface and the tool.

17. The implement of claim 13 , wherein first portion interface feature, the first and second second portion interface features, and the third portion interface feature collectively comprise at least two slots and at least two corresponding tabs configured to be received in the slots.

18. The implement of claim 13 , wherein the first, second and third backscreen portions include a plurality of vertically oriented members.

19. The implement of claim 13 , wherein at least one of the first, second and third backscreen portions include a screen or grid of vertically oriented members and horizontally oriented members.
