ABSTRACT:
An improved rechargeable flashlight having a casing of dielectric material including adapter means for recharging the batteries from a power source such as a battery in a vehicle, said adapter means including a phono plug terminal mating with a phono jack in the flashlight's casing wall and a terminal plug for insertion into a conventional cigarette lighter receptacle on a vehicle's dashboard, said terminal plug having a current limiting resistor in the charging circuit to provide a safe charging voltage and current to the rechargeable batteries in the flashlight and preferably an LED (light emitting diode) is in the charging circuit to indicate charging current is being received from the charging source and accepted by the flashlight batteries. Further included is an integral cross-member within the flashlight casing serving as a fixed partition between the batteries in the flashlight casing and the flashlight bulb thereby isolating the bulb against shock impact from battery movement, an on-off switch mechanism comprising an internal bus bar which is movable fore and aft in the flashlight casing and has at one end an electrical connection to the photo plug socket in the flashlight casing wall and at its other end a continuous electrical contact with a metal sleeve attached to the interior wall of the casing and a flexible spare bulb holder insertable in the flashlight's rear end cap.
This invention relates to improvement in rechargeable flashlights.
