First Claim
Patent Images
1. A rechargeable flashlight system comprisinga hollow barrel to receive at least one battery;
- a head assembly mounted on one end of the barrel;
a tail cap at the other end of the barrel;
an insulator within the hollow barrel at the head assembly;
an electrical circuit;
the insulator providing a lamp bulb socket and a recess facing inwardly of the barrel to receive a battery terminal;
the head assembly having a reflector and a lens movable relative to the insulator;
the tail cap being movable between a first position and a second position relative to the barrel;
the electrical circuit having a lamp bulb positioned in the socket and extending to centrally of the reflector, two electrical conductors in electrical contact with the lamp bulb, a first of the electrical conductors extending to within the recess in the insulator, an electrical switch at the tail cap having a first tail cap switch contact fixed relative to the tail cap and extending into the hollow barrel and a second tail cap switch contact fixed relative to the barrel, the tail cap switch contacts being mutually spaced apart with the tail cap in the first position and touching with the tail cap in the second position, a second of the electrical conductors being coupleable with the second tail cap switch contact, a first charger contact on the barrel coupled with the second tail cap switch contact, a one-way current flow diode and a second charger contact on the tail cap coupled with the first tail cap switch contact through the diode.
