Abstract

Embodiments are described that provide a flashlight including a head, a lamp and at least one head electrical lead, a first body that is removably connected to the head, the first body including a battery compartment and a first body electrical contact to connect with the head electrical lead, and wherein the head and the first body are removably connected to each other with quick-disconnect coupling means. The flashlight may also include inductive charging coils disposed in the first body to permit the battery to be inductively recharged without being removed from the first body. The flashlight may include a rotatable annular ring for adjusting the flashlight between spot, flood and spot/flood modes utilizing Hall Effect sensors to facilitate the shifting between the modes. Other embodiments may be described and claimed.

Claims

1. A flashlight comprising:

a head, including a lamp and at least one head electrical lead;

a first body that is removably connected to the head, the body including a battery compartment and a first body electrical contact to connect with the at least one electrical lead; and

wherein the head and the first body are removably connected to each other with quick-disconnect coupling means.

2. The flashlight of claim 1, further comprising a second body that may be connected to the head in place of the first body, the second body including a second battery compartment and a second body electrical contact to connect with the at least one electrical lead;

and

wherein the head and the second body are removably connected to each other with second quick-disconnect coupling means.

3. A flashlight comprising:

a head, including a lamp electrical lead and at least one head electrical lead;

a first body that is removably connected to the head, the body including a battery compartment and a first body electrical contact to connect with the at least one electrical head;

wherein the head and the first body are removably connected to each other with a first quick-disconnect coupling including a first sleeve that is slidably mounted to the first body, the first sleeve having a variety of inwardly-facing surfaces at various heights designed to control a position of a plurality of hardened balls with respect to at least one orifice in the first body and at least one aperture in the head, the at least one orifice and the at least one aperture serving to engage and disengage the first body from the head, while simultaneously connecting the lamp electrical lead and the first body electrical contact.

4. The flashlight of claim 3, further comprising a second body that may be connected to the head in place of the first body, the second body including a second battery compartment and a second body electrical contact to connect with the at least one electrical head;

wherein the head and the second body are removably connected to each other with a second quick-disconnect coupling including a second sleeve that is slidably mounted to the second body, the second sleeve having a variety of inwardly-facing surfaces at various heights designed to control a position of a plurality of hardened balls with respect to at least one orifice in the second body and at least one aperture in the head, the at least one orifice and the at least one aperture serving to engage and disengage the second body from the head, while simultaneously connecting the lamp electrical lead and the second body electrical contact.

5. The flashlight of claim 3, further comprising at least one battery mounted into the battery compartment of the first body.

6. The flashlight of claim 5, wherein the at least one battery is a rechargeable battery.

7. The flashlight of claim 6, further comprising a charging stand for recharging the at least one battery.

8. The flashlight of claim 3, further comprising a rotatable annular ring for adjusting the flashlight between spot, flood and spot/flood modes.

9. The flashlight of claim 8 wherein the annular ring includes a magnet that cooperates with Hall Effect sensors to facilitate the shifting between spot, flood and spot/flood modes.

10. The flashlight of claim 8, further comprising detent means for permitting an operator to sense when the annular ring has been rotated sufficiently to shift between the modes.

11. The flashlight of claim 3, further comprising first inductive charging coils disposed in the first body to permit the battery to be inductively recharged without being removed from the first body.

12. A rechargeable flashlight system comprising:

a flashlight having a head, including a lamp electrical lead and at least one electrical lead;

a first body that is removably connected to the head, the body including a battery compartment and an electrical contact to connect with the at least one electrical lead in the head;

wherein the head and the first body are removably connected to each other with a first quick disconnect coupling including a sleeve that is slidably mounted to the first body, the sleeve having a variety of inwardly-facing surfaces at various heights designed to control a position of a plurality of hardened balls with respect to at least one orifice in the first body and at least one aperture in the head, the at least one orifice and the at least one aperture serving to engage and disengage the body from the head, while simultaneously connecting the lamp electrical lead and the body electrical contact; and

an inductive charging stand comprising primary inductive coils designed to alternatively cooperate with secondary inductive coils disposed in the first body when the body is positioned in close proximity to the inductive charging stand to inductively recharge batteries when the batteries are disposed in the first body.

14. The rechargeable flashlight system of claim 12, further comprising a system for shifting between spot, flood and spot/flood modes including Hall Effect sensors to facilitate the shifting between the modes.

15. The rechargeable flashlight of claim 14 wherein the system for shifting between spot, flood and spot/flood modes includes a rotatable annular ring having a magnet therein for cooperating with the Hall Effect sensors to shift the flashlight between the modes.

16. The rechargeable flashlight of claim 15, further comprising detent means for permitting an operator to sense when the annular ring has been rotated sufficiently to shift between the modes.

13. The rechargeable flashlight system, further comprising:

a second body that may be removably connected to the head in place of the first body, the second body including a second battery compartment and a second body electrical contact to connect with the at least one electrical lead in the head;

wherein the head and the second body are removably connected to each other with a second quick disconnect coupling including a second sleeve that is slidably mounted to the second body, the second sleeve having a variety of second inwardly-facing surfaces at various heights designed to control a position of a plurality of second hardened balls with respect to the at least one orifice in the second body and the at least one aperture in the head, the at least one orifice in the second body and the at least one aperture serving to engage and disengage the second body from the head, while simultaneously connecting the lamp electrical lead and the second body electrical contact.

17. A flashlight comprising:

a head, including a lamp and at least one head electrical lead;
