Abstract

A trimmer that is operable to cut at least one sheet of paper includes a base configured to support the at least one sheet, a rail extending across at least a portion of the base, and a cutting assembly having a carriage slidably coupled to the rail and a blade positioned on the carriage. The trimmer also includes a blade opposing member coupled to the base adjacent to the rail and an indicator operable to display a usable life status of at least one of the blade and the blade opposing member.

Claims

1. A trimmer operable to cut at least one sheet, the trimmer comprising:

a base configured to support the at least one sheet;

a rail extending across at least a portion of the base;

a cutting assembly including a carriage slidably coupled to the rail and a blade positioned on the carriage;

a blade opposing member coupled to the base adjacent to the rail; and

an indicator operable to display a usable life status of at least one of the blade and the blade opposing member.

2. The trimmer of claim 1, wherein the indicator is incrementally adjusted with each cutting motion performed by the blade.

3. The trimmer of claim 1, wherein the indicator is positioned on the cutting assembly.

4. The trimmer of claim 1, wherein the indicator is positioned on the base.

5. The trimmer of claim 1, wherein the indicator is incremented in response to sliding the carriage along the rail.

6. The trimmer of claim 5, wherein the indicator includes a visual indication portion and a count button coupled to the visual indication portion, and wherein sliding the blade along the rail actuates the count button to increment the visual indication portion.

7. The trimmer of claim 6, wherein the indicator includes a reset button coupled to the visual indication portion, and wherein actuating the reset button resets the visual indication portion.

8. The trimmer of claim 7, wherein the blade opposing member is removable from the base, and wherein moving a portion of the blade opposing member apart from the base actuates the reset button to reset the visual indication portion.

9. The trimmer of claim 1, wherein the usable life status notifies a user to replace the blade.

10. The trimmer of claim 1, wherein the cutting assembly includes a cartridge detachably coupled to the carriage, and wherein the blade is positioned at least partially within the cartridge.

11. The trimmer of claim 10, wherein the indicator is positioned on the cartridge.

12. The trimmer of claim 11, wherein the cartridge includes a window, and wherein at least a portion of the indicator is visible through the window.

13. The trimmer of claim 1, wherein the cutting assembly includes a housing, and wherein the blade is movable between a first position in which the blade is positioned entirely within the housing, and a second position in which a portion of the blade extends from the housing.

14. The trimmer of claim 13, wherein the indicator is actuated in response to moving the blade to the second position.

15. The trimmer of claim 13, wherein the blade is biased to the first position, and wherein the cutting assembly includes an actuator operable to move the blade to the second position.

16. The trimmer of claim 15, wherein the indicator includes a disc and a gear train coupled between the actuator and the disc, and wherein actuating the actuator activates the gear train to rotate the disc.

17. The trimmer of claim 1, wherein the blade opposing member is a cutting mat removably coupled to the base, and wherein the usable life status notifies a user to replace the cutting mat.

18. The trimmer of claim 1, wherein the blade opposing member includes a first layer having a first color and a second layer having a second color that is substantially different than the first color, wherein the indicator includes the second layer, and wherein the second layer is disposed beneath the first layer such that the second layer becomes visible to indicate a diminished usable life of the blade opposing member.

19. The trimmer of claim 18, wherein the first layer and the second layer are molded together as a single piece.

20. The trimmer of claim 1, wherein the blade opposing member includes a first mat portion and a second mat portion positioned on opposite sides of the blade opposing member, and wherein the blade opposing member is reversible from a first position, in which the blade engages the first mat portion, to a second position, in which the blade engages the second mat portion.

21. The trimmer of claim 20, wherein the blade opposing member includes a substrate positioned substantially between the first mat portion and the second mat portion to separate the first and second mat portions.
