Abstract

A lighted level tool comprising a body including at least one vial opening, a vial disposed at least partially within the at least one vial opening, a light source for illuminating the vial, an insert member mounted at a predetermined location in the body relative to the at least one vial opening, and at least one an end cap mounted at an end of the body. The insert member is configured to receive the vial therein and to hold the light source opposite an end of the vial. A control circuit for powering the light source is mounted in the at least one end cap.

Claims

1. A level tool comprising:

a body including at least one vial opening;

a vial disposed at least partially within the at least one vial opening;

a light source for illuminating the vial; and

an insert member mounted at a predetermined location in the body relative to the at least one vial opening, the insert member having a unitary, one-piece construction configured to receive the vial therein and to hold the light source opposite an end of the vial,

wherein the insert member includes a light source mount extending in a direction generally perpendicular to a wall of the insert member for holding the light source opposite an end of the vial.

2. The level tool of claim 1, wherein the insert member has a generally U-shaped cross-sectional shape that defines an internal cavity for receiving the vial, and wherein the light source mount forms a protrusion that defines an opening in a side wall of the insert member for holding the light source opposite the end of the vial.

3. The level tool of claim 2 further comprising a generally U-shaped bracket configured to mount the insert member to the body at least partially within a rectangular vial opening.

4. The level tool of claim 1, wherein the insert member defines a central opening in a face of the insert member for receiving the vial therein, and wherein the light source mount forms a projection extending in a direction generally perpendicular to the face of the insert member for holding the light source opposite the end of the vial.

5. The level tool of claim 1 further comprising at least one end cap mounted at an end of the body and a control circuit for powering the light source housed in the at least one end cap, wherein the end cap is made of an elastomeric material.

6. The level tool of claim 5, wherein the control circuit includes a battery pack and a switch electrically connected to the battery pack for selectively energizing the light source.

7. The level tool of claim 6, wherein the control circuit includes an automatic shut-off circuit electrically connected to the battery pack for turning off the light source.

8. The level tool of claim 6, wherein the end cap includes a battery compartment for holding the battery pack and a detachable battery cover mounted on the end cap for accessing the battery pack.
