Abstract

A flashlight is disclosed having a body and a flashlight head in which a light bulb is mounted. The body includes a housing that defines a battery compartment, a pair of arms extending from a front end of the housing for mounting the flashlight head between opposing ends of the arms such that the flashlight head may be pivoted relative to the body, and a thumb wheel rotatably mounted in the housing and extending partially through the housing to engage the flashlight head such that the flashlight head pivots relative to the body as the thumb wheel is rotated. The thumb wheel may include gear teeth about its perimeter for engaging gear teeth formed in the round rear surface of the flashlight head.

Claims

1. A flashlight comprising:

a flashlight head including a light bulb; and

a body including;

a housing that defines a battery compartment,

a pair of arms extending from a front end of said housing for mounting said flashlight head between opposing ends of said arms such that said flashlight head may be pivoted relative to said body, and

a thumb wheel rotatably mounted in said housing and extending partially through said housing to engage said flashlight head such that said flashlight head pivots relative to said body as said thumb wheel is rotated.

2. The flashlight as defined in claim 1, wherein said housing has an elongated shape contoured to fit in the palm of a person'"'"'s hand.

3. The flashlight as defined in claim 2, wherein said body further includes a switch disposed partially in said body and extending through a side of said housing opposite a side of said housing through which said thumb wheel extends such that said switch may be depressed with a person'"'"'s forefinger while said thumb wheel may be rotated with the person'"'"'s thumb.

4. The flashlight as defined in claim 1, wherein said thumb wheel includes a plurality of gear teeth and said flashlight head includes a round rear surface having a plurality of parallel grooves for engaging said gear teeth of said thumb wheel.

5. The flashlight as defined in claim 4 and further including a detent disposed within said housing for releasably engaging said gear teeth of said thumb wheel.

6. The flashlight as defined in claim 1 and further including a pair of pivot pins extending towards one another from opposing ends of said arms, wherein said pivot pins enable said flashlight head to pivot about an axis extending between said pins.

7. The flashlight as defined in claim 6, wherein said arms extend from said housing at an angle inclined from a central axis of said housing such that the axis extending between said pivot pins does not intersect the central axis of said housing.

8. A flashlight comprising:

a body housing;

a head housing pivotally mounted to said body housing, said head housing including a round rear surface having a plurality of parallel grooves provided therein; and

a thumb wheel rotatably mounted in said body housing and extending partially through a side and an end of said body housing, said thumb wheel including a plurality of gear teeth for engaging said grooves in said head housing such that said head housing pivots relative to said body housing as said thumb wheel is rotated.

9. The flashlight as defined in claim 8 and further including a battery compartment within said body housing.

10. The flashlight as defined in claim 8 and further including a detent disposed within said body housing for releasably engaging said gear teeth of said thumb wheel.

11. The flashlight as defined in claim 8 and further including a light bulb disposed in said head housing.

12. The flashlight as defined in claim 8 and further including a switch disposed partially within said body housing.

13. The flashlight as defined in claim 8, wherein said body housing includes a pair of arms extending from a front end of said body housing, and a pair of pivot pins extending towards one another from opposing ends of said arms, wherein said pivot pins enable said head housing to pivot about an axis extending between said pins.

14. The flashlight as defined in claim 13, wherein said arms extend from said body housing at an angle inclined from a central axis of said body housing such that the axis extending between said pivot pins does not intersect the central axis of said body housing.

15. A flashlight comprising:

a flashlight head including a light bulb; and

a body including;

a housing that defines a battery compartment,

a pair of arms extending from a front end of said housing for mounting said flashlight head between opposing ends of said arms such that said flashlight head may be pivoted relative to said body and thereby provide benchtop illumination, and

a pair of pivot pins extending towards one another from opposing ends of said arms, wherein said pivot pins enable said flashlight head to pivot about an axis extending between said pins, wherein said arms extend from said housing at an angle inclined from a central axis of said housing such that the axis extending between said pivot pins does not intersect the central axis of said housing.

16. The flashlight as defined in claim 15, wherein said housing has an elongated shape contoured to fit in the palm of a person'"'"'s hand.

17. The flashlight as defined in claim 16, wherein said body further includes a switch disposed partially in said body and extending through a side of said housing such that said switch may be depressed with a person'"'"'s forefinger.
