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 recharger 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 portion being the barrel, an intermediate section and a head. The flashlight is loaded with batteries from the front. There are contacts on an intermediate portion above the barrel opposite to a switch device in the intermediate portion. A helical spring is loaded at the top of the battery and another helical spring is at the bottom of the battery to retain the battery in a shock-absorbing mode. The helical spring at the bottom is located between the contact strip at the base of the barrel and the battery, and is in electrical contact with the battery. The helical 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 top helical spring is in electrical contact. Above the intermediate section is located an enlarged head which includes a lens and a bulb.
A recharger is provided to connect with the contacts on the intermediate portion when in recharging mode. The recharger device includes arms or jaws which preferably engage the flashlight around the barrel so that the contacts on the recharger can make electrical contact with the contacts on the intermediate portion of the flashlight.
The invention is further described with reference to the accompanying drawings.
