Abstract

A utility knife includes a body having a front end and a rear end opposite the front end. A blade holder, supported by the body, is moveable relative to the body, to move a blade between an extended position and a retracted position. The blade extends through a blade aperture when in the extended position. The blade aperture is sized to receive a hook attached to the blade of a tape measure.

First claim

What is claimed is:

1. A utility knife comprising:
a body comprising a front end and a rear end opposite the front end and a first body portion cooperating with and coupled to a second body portion, the first and second body portions both extend along a length direction of the body between the front end and rear ends and together define an interior portion of the body;
a blade holder supported by the body within the interior portion of the body, the blade holder moveable relative to the body to move a blade between an extended position and a retracted position, wherein the first body portion surrounds a first side of the blade holder and the second body portion surrounds a second side of the blade holder such that the blade holder is enclosed within the body; and
a blade aperture positioned at the front end of the body, the blade aperture defined between a first edge of the first body portion and a second edge of the second body portion, through which the blade extends out of the body when in the extended position, the blade aperture including a central section having a width defined between the first edge of the first body portion and the second edge of the second body portion and a height and a first end section having a width and a height, the width of the central section is greater than the width of the first end section, the height of the central section is greater than the height of the first end section;
wherein the first edge of the first body portion faces a first side of the blade and the second edge of the second body portion faces a second side of the blade and wherein the first edge of the first body portion opposes the second edge of the second body portion when the first body portion is coupled to the second body portion.

2. The utility knife of claim 1 , wherein the blade aperture further comprises a second end section having a width and a height, the width of the central section is greater than the width of the second end section, the height of the central section is greater than the height of the second end section.

3. The utility knife of claim 2 , wherein the respective widths of the first end section and the second end section of the blade aperture are each less than 50% of the width of the central section of the blade aperture, and the height of the central section of the blade aperture is greater than 80% of both of the respective heights of the first end section and the second end section of the blade aperture.

4. The utility knife of claim 2 , wherein the width of the first end section is equal to the width of the second end section, and the height of the first end section is equal to the height of the second end section.

5. The utility knife of claim 1 , wherein the blade aperture is defined in the front end of the body, wherein the blade holder is slidable relative to the body to move the blade through the blade aperture between the extended position and the retracted position.

6. The utility knife of claim 1 , wherein the blade holder comprises a lock member coupled to a resilient spring arm.

7. The utility knife of claim 6 , wherein the lock member is coupled to an actuator button wherein the actuator button is slidable along a slot that extends through the first body portion of the body.

8. The utility knife of claim 7 , further comprising a plurality of projections formed on the interior portion of the body and spaced along the slot such that the lock member is selectively receivable between adjacent pairs of projections to retain the blade holder in a position.

9. The utility knife of claim 1 , wherein the blade projects a maximum distance from the front end when in a fully extended position and the blade is enclosed by the body when in a fully retracted position.

10. The utility knife of claim 1 , wherein the blade holder further includes an outer surface defining an outer perimeter and the first body portion includes a first interior surface and the second body portion includes a second interior surface, wherein the first interior surface and second interior surface together extend around the outer perimeter of the blade holder.
