Abstract

A cutting device has a selectively replaceable and reorientable blade. The cutting device includes a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device also has a cutting member that is removably disposable and reorientable in the carriage and a cover member that is removably attachable to the housing. Further, the cutting device includes an adjustable blade depth assembly providing the ability to direct and/or pre-select the depth or length a blade disposed in the carriage will reach upon engagement of a dial component and/or switch member operably connected to the blade carriage.

First claim

What is claimed is:

1. A cutting device, comprising:
a housing;
a blade carriage that is movably disposed in the housing, the blade carriage having a blade channel configured to releasably receive a blade, and the blade carriage being movable between a retracted position and an extended position;
a position adjustment assembly in mechanical communication with the carriage, the position adjustment assembly comprising at least a dial component having a post component extending therefrom, with a position setting component disposed between a pair of flanges extending from a position indicator component and adapted to travel along the post component to direct movement of the blade carriage to one or more blade carriage positions corresponding to one or more position setting component positions;
a cover member that is removably attached to a portion of the housing and formed with a blade outlet slot; and
wherein the blade channel comprises one or more locking tabs adapted to releasably secure the blade in a first position wherein a top side of the blade aligns with a top side of the blade channel and a second position wherein a top side of the blade aligns with a bottom side of the blade channel.

2. The cutting device of claim 1 , wherein removal of the cover member exposes at least a portion of the carriage and the blade disposed therein.

3. The cutting device of claim 1 , wherein the blade channel comprises one or more locking members.

4. The cutting device of claim 3 , wherein each locking member comprises one or more tab implements and one or more indented portions.

5. The cutting device of claim 4 , wherein at least one of the tab implements is adapted to be releasably received in at least one blade notch, and at least one of the indented portions is adapted to selectively receive a portion of the cutting edge of the blade.

6. The cutting device of claim 5 , wherein at least one of the tab implements is adapted to receive a rear edge of the blade.

7. A cutting device, comprising:
a housing that is a handle;
a blade carriage that is movably disposed in the housing, the blade carriage operably engaged with a switch member and having a blade channel, the blade carriage being movable between a retracted position and an extended position;
a blade having one or more notches, the blade being removably disposed in the blade channel;
a position adjustment assembly in mechanical communication with the carriage, the position adjustment assembly comprising at least a dial component extending towards a threaded post having a position setting component disposed between a pair of flanges extending from a position indicator component, the position setting component adapted to laterally travel along the threaded post upon rotation of the dial component to move the position setting component and restrict movement of the blade carriage past a selected position of the position setting component; and
a blade cover having a blade outlet slot, the blade cover being removably attachable to a portion of the housing;
wherein the blade channel comprises one or more locking members comprising one or more tab implements and one or more indented portions, at least one of the tab implements adapted to be releasably received in at least one blade notch, and at least one of the indented portions adapted to selectively receive a portion of the cutting edge of the blade.

8. The cutting device of claim 7 , wherein the housing is formed with a position indicator slot.

9. The cutting device of claim 7 , wherein the blade carriage is operably connected to a tension component configured to bias the blade carriage towards the retracted position.

10. The cutting device of claim 7 , wherein the locking members are configured to releasably secure the blade in a first position wherein a top side of the blade aligns with a top side of the blade channel and a second position wherein the top side of the blade aligns with a bottom side of the blade channel.

11. The cutting device of claim 7 , the position indicator component is configured to indicate a depth the blade will travel upon engagement of the switch member.

12. The cutting device of claim 11 , wherein a movement of the position indicator component corresponds to a movement of the position setting component.

13. A cutting device, comprising:
a housing that is a handle sized and dimensioned to fit in a user hand;
a blade having a top side formed with one or more notches opposing a bottom side formed as a cutting edge;
a moveable blade carriage disposed in the housing and formed with a blade channel configured to receive a blade, the blade channel having a top edge formed with a first locking member opposing a bottom edge formed with a second locking member, and a rear edge formed with a third locking member, each locking member comprising one or more tab implements and one or more indented portions, at least one of the tab implements adapted to be releasably received in at least one blade notch, and at least one of the indented portions adapted to selectively receive a portion of the cutting edge of the blade;
a switch member in mechanical communication with the blade carriage;
a blade cover removably attached to the housing adapted to provide access to blade carriage;
a blade adjustment assembly comprising a dial component extending towards a threaded post having a rotatable member disposed thereon adapted to laterally travel along the threaded post upon rotation of the dial component to move the rotatable member and restrict movement of the blade carriage past a point defined by the position of the rotatable member;
a position indicator component comprising a pair flanges between which the rotatable member is disposed, the position indicator component configured to indicate a position of the rotatable member.

14. The cutting device of claim 13 , wherein the rotatable member defines a forward movement boundary of the blade carriage.

15. The cutting device of claim 13 , wherein the threaded post is disposed alongside the blade carriage.

16. The cutting device of claim 13 , wherein the locking members are configured to releasably secure the blade in a first position wherein the top side of the blade aligns with the top side of the blade channel and a second position wherein the top side of the blade aligns with the bottom side of the blade channel.

17. The cutting device of claim 13 , wherein movement of the rotatable member directs movement of the position indicator component.

18. The cutting device of claim 17 , wherein at least one of the flanges of the position indicator component is configured to abut a portion of the blade carriage upon a forward movement of the switch member to prevent movement of the blade carriage past a position of at least one of the flanges of the position indicator component.
