Abstract: A rechargeable flashlight, having a head end and a tail end, has an incandescent bulb disposed to direct its illumination out of the head end and has a switch accessible at the tail end. The flashlight houses an assembly of rechargeable batteries and a voltage converter that steps up the voltage provided by the rechargeable batteries and powers the incandescent bulb with the stepped-up voltage when the switch is in the “ON” position. When the switch is in the “OFF” position, the rechargeable batteries may be recharged while they are inside of the flashlight, via positive and negative contact rings disposed coaxially about the switch in the tail end of the flashlight. A recharger is positioned to provide current through the positive and negative contact rings for recharging the batteries inside the flashlight when protrusions carried on the recharger housing snap into a circumferential groove provided in the flashlight housing.

Abstract: A flashlight having a power source and a light source having a high intensity positioned in a power source frame. The flashlight further includes a power source frame housing that encloses the power source frame. The frame and the housing cooperate to secure and protect the internal components of the flashlight. The flashlight is further provided with side covers that have flat surfaces to receive markings or engravings. A switch is provided to activate the light source, the switch preferably providing tactile feedback to the user.

Abstract: A lamp assembly for a flashlight including an assembly member, a base carrying a bulb, a board containment member for containing the base within the assembly member, and a fastener for retaining the board containment member against the base. The fastener has external threading which mates with internal threading provided in the through bore of the assembly member.

Abstract: The flashlight of the present invention is comprised generally of a flashlight chassis which houses energy cells, a flashlight head which houses a beam adjustment assembly, and an endcap which houses a switch assembly. The beam adjustment assembly and the switch assembly utilize printed circuit boards to support the lamp bulb and switch, respectively. The beam adjustment assembly mounts inside the flashlight head and can only be accessed and adjusted by removing the outer lens retaining ring that secures the assembly within the head. Once accessed, the bulb support of the assembly can be rotated relative to the reflector of the assembly to adjust the light focal length of the flashlight. The adjustment assembly is also provided with a shock absorber that supports the light bulb. In one embodiment, the endcap is provided with a threads to permit the flashlight to be axially attached to an expandable baton.

Abstract: A battery recharger that can be used with a standard flashlight having a flared head and a generally cylindrical body includes a recharger unit that accepts flashlight batteries for recharging and a clamping structure that grasps the flashlight where the flashlight head joins the flashlight body and exerts enough clamping force to support the weight of the recharger unit when it contains the batteries. Substantially all of the flashlight body is free to be used as a carrying handle and also to be used as a lever arm to remove the flashlight from the grip of the clamping structure. The recharger includes recharging circuitry that can fully charge high-performance battery sticks up to their rated power of 4.4 amp-hours. The recharger accepts both two-cell and three-cell size battery sticks, and can be moved about to whatever locations are necessary.

Abstract: A flashlight includes a barrel portion for enclosing and retaining batteries and comprising an end for accepting a movable bulb enclosure. The moveable bulb enclosure engages the end of the barrel so that the bulb enclosure is axially movable along the barrel portion. A bulb holder is provided at the second end for removably holding a bulb such that the bulb is relatively stationary during axial movement of the bulb enclosure. A stop is provided on the end of the barrel portion for preventing complete removal of the movable bulb enclosure from the barrel portion.

Abstract: A switch for a portable light source such as a flashlight which has a housing for carrying one or more batteries and for supporting a lamp bulb. The switch includes a switch body securable to the housing and an actuator that is axially moveable relative to the switch body for electrically coupling and uncoupling an electrode of the batteries to one of the terminals of the lamp bulb to switch the lamp bulb on and off. The actuator is also rotatably moveable relative to the switch body to prevent axial movement of the actuator and thereby lock the flashlight in the on state.
