Abstract

This invention relates generally to an illumination system that is configured for attachment to a hard hat or the temple arm portion of a pair of eyeglasses. The illumination system includes a light source and a multi-axis pivot assembly to permit directional adjustment and focus of a beam of light. An adapter clip is provided to facilitate attachment to the temple arm portion of the eyeglasses. The adapter clip includes a plurality of grooves positioned between two flexible side portions to allow the clip to be slid along the temple arm to a desired position and snapped into a locked position. The illumination system is fully adjustable in terms of light intensity and direction of the light beams.

Claims

1. An illumination system securable to a hard hat comprising:

an adapter bracket constructed and arranged for attachment to a hard hat, said adapter bracket being substantially L-shaped having a first leg sized to fit into a slot integrally formed into the side of a hard hat and a second leg including at least one first portion of a bearing member for releasable rotational cooperation with an offset arm, said first portion of said bearing member being positioned on an outside surface of said second leg;

an offset arm being substantially L-shaped when viewed from an end, said offset arm having a second portion of a bearing member positioned on an outside surface of a first leg for snap together cooperation with said first portion of said bearing member on said adapter bracket, said bearing members providing rotation of said offset arm with respect to said adapter bracket while securing said offset arm to said adapter bracket, a second leg of said offset arm including a first portion of a bearing member on an inner surface thereof for snap together cooperation with a light source holder;

a light source holder being generally C-shaped when viewed from an end, said light source holder having an inner bore sized to frictionally cooperate with a self-contained light source, an outer surface of said light source holder including a second portion of a bearing member for snap together cooperation with said first portion of a bearing member on said second leg of said offset arm, whereby said light source holder is free to rotate about said bearing members and said light source holder is secured to said offset arm.

2. The illumination system of claim 1 wherein said first leg of said adapter bracket includes a catch member, said catch member constructed and arranged to cooperate with a surface within said hard hat slot to releasably secure said adapter bracket to said hard hat.

3. The illumination system of claim 2 wherein said catch member includes a ramp side and a catch side, said ramp side constructed and arranged to deflect a portion of said slot, whereby said deflected portion snaps back to engage said catch side.

4. The illumination system of claim 1 wherein said offset arm includes an S-shape when viewed from the side, said offset arm rotatable to move said light source forward or backward with respect to said adapter bracket.

5. The illumination system of claim 1 wherein said second leg of said adapter bracket includes a second first portion of a bearing assembly for releasable rotational cooperation with an offset arm, said second first portion of said bearing assembly being positioned on an inside surface of said second leg, whereby said offset arm is constructed and arranged to cooperate with either said first portion of a bearing assembly to allow said offset arm to be extended in opposite directions with respect to said adapter bracket.

6. The illumination system of claim 1 wherein said first and said second portions of said bearing assembly are constructed and arranged to break away from each other in the event that a portion of said illumination assembly is inadvertently caught on a foreign object.

7. The illumination system of claim 1 wherein said bearing assembly includes a post and a socket which snap together for connection.

8. The illumination system of claim 7 wherein said socket includes an undercut in said socket to provide for a snap lock assembly.

9. The illumination system of claim 7 wherein said post is split having a pair of spaced apart legs.

10. The illumination system of claim 1 wherein the positions of said first and said second bearing members are reversed.

11. The illumination system of claim 1 wherein said adapter bracket is replaced by an adapter clip, whereby said offset arm and said light source holder are securable to the temple arm portion of a pair of eyeglasses.

12. The illumination system of claim 11 wherein said adapter clip comprises a substantially L-shaped portion having a closure member hingedly secured to the first leg of said closure member, whereby a second end of said closure member cooperates with a second leg of said closure member to close said adapter clip around said temple arm, said closure member including a first portion of a bearing member on an outer surface thereof.

13. The illumination system of claim 12 wherein said second leg of said L-shaped portion includes a plurality of ridges, said ridges constructed and arranged to cooperate with an end portion of said closure member to maintain said adapter clip in a closed position.

14. The illumination system of claim 11 wherein an inner surface of said closure member includes grooves sized and shaped to cooperate with the temple arm portion of a pair of glasses, whereby said temple arm portion of said glasses is retained within one of said grooves.

15. The illumination system of claim 14 wherein said grooves are sized progressively to cooperate with different sized temple arms.
