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 arc known which are rechargeable. There are also different forms of charging device for use with flashlights. The different combinations provide for a configuration of flashlight and charging 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 with a body being a barrel, an intermediate section and a head. The flashlight is loaded with a battery pack from the rear. There are contacts on the barrel opposite to a switch device in the intermediate section. A leaf spring is located at the top of the battery and another helical spring is located at the bottom of the battery. The springs retain the battery in a shock absorbing mode. The helical spring at the bottom is located between the base of the barrel and the battery and is not in an electrical contact with the battery. The leaf spring at the top is located between the battery and a switching device which is transversely mounted in an intermediate section above the barrel of the flashlight.
The leaf spring at the top is in contact with the battery. A solid stud below the switching device contacts the central contact of the battery, and a peripheral tangential leaf spring contact makes electrical contact with a peripheral contact of the battery which is connected through an elongated strip with the lower terminal of the battery pack.
Above the intermediate section is located an enlarged head which includes a lens and a bulb.
A charger is provided to connect with the contacts on the intermediate portion when in recharging mode. The charger device includes arms or jaws, which preferably engage the flashlight around the barrel so that the contacts on the charger can make electrical contact with the contacts on the barrel of the flashlight.
The invention is further described with reference to the accompanying drawings.
