Abstract

A trimmer head for use with a trimmer. The trimmer head includes a housing rotatable about an axis, the housing defining a cavity for receiving a spool carrying a length of trimmer line, the housing further defining a housing mating feature. The trimmer head also includes a first cap member having a first mating feature formed as one piece with the first cap member and operable to cooperate with the housing mating feature. The trimmer head also includes a second cap member having a second mating feature formed as one piece with the second cap member and operable to cooperate with the housing mating feature. The second cap member provides a cutting feature independent from the trimmer line. The first cap member and the second cap member are releasably and interchangeably coupleable to the housing without the use of tools.

Claims

a second cap member having a second mating feature operable to cooperate with the housing mating feature to selectively and releasably couple the second cap member with the housing, the second mating feature being formed as one piece with the second cap member, the second cap member providing a cutting feature independent from the trimmer line;

wherein the first cap member and the second cap member are releasably and interchangeably coupleable to the housing without the use of tools.

2. The trimmer head of claim 1, wherein the second mating feature is substantially identical to the first mating feature.

3. The trimmer head of claim 1, wherein the first mating feature and the second mating feature include snap-fits.

4. The trimmer head of claim 3, wherein at least one of the first mating feature and the second mating feature includes a prong and a flange for snap-fitting to the housing.

5. The trimmer head of claim 4, wherein the housing mating feature includes an opening in the housing for receiving the flange.

6. The trimmer head of claim 1, wherein the cutting feature provided by the second cap member includes at least one blade.

7. The trimmer head of claim 6, wherein the at least one blade is pivotably coupled to the second cap member and extends radially therefrom.

8. The trimmer head of claim 7, wherein the at least one blade includes cutting teeth.

9. The trimmer head of claim 8, wherein the cutting teeth are positioned along opposing longitudinal edges of the at least one blade.

10. The trimmer head of claim 9, wherein the at least one blade further includes a beveled cutting edge disposed at a distal end thereof.

11. The trimmer head of claim 1, wherein the cutting feature provided by the second cap member includes at least one fixed string.

12. A landscape trimmer comprising:

a motor;

an output shaft driven by the motor; and

a trimmer head including

a housing rotatable about an axis, the housing defining a cavity for receiving a spool carrying a length of trimmer line, the housing further defining a housing mating feature,

a first cap member having a first mating feature operable to cooperate with the housing mating feature to selectively and releasably couple the first cap member with the housing, the first mating feature being formed as one piece with the first cap member, the first cap member cooperating with the housing to retain the spool in the cavity, and

a second cap member having a second mating feature operable to cooperate with the housing mating feature to selectively and releasably couple the second cap member with the housing, the second mating feature being formed as one piece with the second cap member, the second cap member providing a cutting feature independent from the trimmer line,

wherein the first cap member and the second cap member are releasably and interchangeably coupleable to the housing without the use of tools.

13. The landscape trimmer of claim 12, wherein the second mating feature is substantially identical to the first mating feature.

14. The landscape trimmer of claim 12, wherein the first mating feature and the second mating feature include snap-fits.

15. The landscape trimmer of claim 14, wherein at least one of the first mating feature and the second mating feature includes a prong and a flange for snap-fitting to the housing.

16. The landscape trimmer of claim 15, wherein the housing mating feature includes an opening in the housing for receiving the flange.

17. The landscape trimmer of claim 12, wherein the cutting feature provided by the second cap member includes at least one blade.

18. The landscape trimmer of claim 17, wherein the at least one blade is pivotably coupled to the second cap member and extends radially therefrom.

19. The landscape trimmer of claim 18, wherein the at least one blade includes cutting teeth.

20. The landscape trimmer of claim 19, wherein the cutting teeth are positioned along opposing longitudinal edges of the at least one blade.

21. The landscape trimmer of claim 20, wherein the at least one blade further includes a beveled cutting edge disposed at a distal end thereof.

22. The landscape trimmer of claim 12, wherein the cutting feature provided by the second cap member includes at least one fixed string.

23. An attachment for a landscape trimmer having a trimmer head including a housing rotatable about an axis, the housing defining a cavity for receiving a spool carrying a length of trimmer line, the housing further defining a housing mating feature, the attachment comprising:

a cap member providing a cutting feature; and

a cap mating feature operable to cooperate with the housing mating feature for selectively and releasably coupling the cap member with the landscape trimmer, the cap mating feature being formed as one piece with the cap member;

wherein the cap member is releasably coupleable to the landscape trimmer without the use of tools or fasteners.

24. The attachment of claim 23, wherein the cap mating feature includes at least one prong extending away from the cap member, the prong including a flange for cooperating with the housing mating feature to selectively and releasably couple the cap member with the landscape trimmer.

25. The attachment of claim 23, wherein the cap member includes a substantially planar portion carrying the cutting feature, and wherein the cap mating feature generally extends away from the substantially planar portion in a direction substantially perpendicular to the substantially planar portion.

26. The attachment of claim 25, wherein the substantially planar portion includes an outer periphery, and wherein the cap mating feature extends substantially from the outer periphery.

27. The attachment of claim 23, wherein the cutting feature includes at least one blade pivotably coupled to the cap member.

28. The attachment of claim 27, wherein the blade includes teeth disposed along a longitudinal edge of the blade, and wherein the blade further includes a beveled cutting edge disposed at a distal end of the blade.

29. The attachment of claim 23, wherein the cutting feature includes at least one fixed string coupled to the cap member.

30. A trimmer head for use with a trimmer, the trimmer head comprising:

a housing rotatable about an axis, the housing including a circumferential wall defining a cavity for receiving a spool carrying a length of trimmer line, the housing further defining a housing mating feature associated with the circumferential wall;
