Abstract:
A flashlight having a mechanism for preventing electrical contact members thereof from rusting comprising:a light mechanism including a bulb, a reflector for securing the bulb, an internal threaded section, an elastic member, a flexible substantially L-shaped conductor coupled to the bulb and having a protuberance on a vertical section, a battery frame including a horizontal section and a plurality of slanted flexible bifurcation members equally spaced on the horizontal section, each bifurcation member having a recess, and one or more batteries each secured between two of the adjacent bifurcation members with electrodes thereof proximate the recesses; a cylindrical container shaped handle for receiving the conductor, the batteries, and the battery frame and including a collar, a raised switch including a channel, two opposed lugs on one end of the channel, a bent trigger member having a projection on a slanted section and a push button on an open end of the slanted section, and a pin through lugs for pivotably securing the trigger member on the channel; and a cylindrical sleeve mechanism put on the handle and including a front outer threaded section matingly secured to the threaded section of the light mechanism together with the collar and the reflector to enclose the elastic member, and an opening on a surface; wherein in an unused position, the batteries are disengaged from each other, a positive electrode of one of the batteries is disengaged from the bulb, and a negative electrode of the other battery is disengaged from the protuberance; and in a used position, the elastic member is compressed by pushing the push button forward for holding the bifurcation members upright and clinging the projection into the opening so that the batteries are electrically coupled together, the positive electrode of one of the batteries is coupled to the bulb, and the negative electrode of the other battery is coupled to the protuberance through the recesses, thereby forming a circuit from the bulb to the protuberance via the batteries.
