ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a rechargeable flashlight. In particular, it relates to a flashlight for use in relatively rugged conditions.
Many flashlight configurations are known. Additionally, different flashlight configurations are known which are rechargeable. There are also different forms of recharging device for use with flashlights. The different combinations provide for a configuration of flashlight and recharging mechanism, which is not as optimum as possible in the sense that the flashlight and charger can be easily set up as a unit. Moreover, they are not convenient for rugged use, for instance, by law enforcement officers, the military and firefighters.
The various flashlights are often not as simple and inexpensive to manufacture as desirable, while at the same time having effective characteristics of longevity and ability to work in harsh conditions and being subjected to shock, and the need for quick recharging as necessary.
The invention is directed to providing a flashlight and recharging system which minimizes the disadvantages of known flashlights.
SUMMARY OF THE INVENTION
By the present invention, there is provided a flashlight which minimizes the disadvantages of known flashlights.
A rechargeable battery flashlight is provided which is loaded from the front. The flashlight has a body with a barrel, an intermediate section above the body, and a head above the intermediate section. There are contacts on the intermediate portion above the barrel. A switch device is located at the bottom of the barrel. A pair of helical springs are located on the underside of a housing for the bulb of the flashlight, peripherally relative to the housing. Above the housing and below the bulbs there is also a centrally located helical spring. These springs are located at the top of the battery.
At the bottom of the battery there is a switch device and a helical spring. The opposite helical springs retain the battery in a shock absorbing mode. The helical spring at the bottom is located effectively between the base of the barrel and the bottom of the battery.
The helical springs at the top are located at a circumferential position and centrally between the battery and the housing which is mounted in an intermediate section above the barrel of the flashlight.
Above the intermediate section there is located the enlarged head which includes a lens and the bulb. A diode is located between the bulb and one of the peripherally located helical springs.
A charger is provided to connect with the contacts on the intermediate portion when in recharging mode. The charger device includes a circumferential housing which preferably engage the flashlight around the barrel so that the contacts on the charger can make electrical contacts of the flashlight.
The outside of the barrel is octagonal, and has one face which is irregular in width relative to the other faces.
The invention is further described with reference to the accompanying drawings.
