  • Flashlight with pivotal legs
    Patent number: 7364320
    Abstract: A handheld flashlight includes a head that pivots relative to a body. Three legs pivotally connect to the body and open into a tripod to support the head in an elevated position. The legs are spring-biased toward the open tripod position and are selectively held closed by a detent mechanism. In the closed position, the legs form a flashlight handle that is aligned with an illumination direction of the head and is shaped and sized to be held in the hand of an operator. Each of the three legs contain battery source holders for battery sources that connect to each other in parallel. Diodes are disposed in series with each battery source to prevent the parallel battery sources from discharging each other.
