Flashlight ball-point pen

Claim 1

An improved flashlight ball-point pen comprising: a cap which includes a cylindrical body; a shaft on which the cylindrical body is rotatably mounted; a battery contained within said cylindrical body; an actuating ring movable with the cap; an engaging member; a shield; an anode plate; a cathode; a shank which forms a ball-point pen reservoir and which includes a nib at one end; a conducting strip; a reflector; a light bulb; a coiled spring and a spiral spring, wherein said actuating ring has a central hole; a ledge at one side facing downwardly towards said nib end; and a recess at a periphery of said actuating ring which forms means for moving said conducting strip with respect to said cathode in response to movement of the cap; wherein said engaging member includes a boss at a central protion, and a passage extending through the boss along an axis of the boss and divided into two partitions; and a through hole extending in a direction of said axis between said boss and the cylindrical body, said engaging member and boss being fixedly connected to said shaft, wherein said shield includes an arcuate glass portion which faces downwardly toward said nib end and a protrusion portion facing upwardly toward said cap and protruding through said through hole to engage said ledge, wherein said shank includes a reflector at a top portion opposite said nib and located underneath and in contact with said shield, wherein said battery has a negative end connected to an end of said coiled spring and a positive end connected to an end of said anode plate, wherein another end of said anode plate extends through the central hole of said acuating ring and through one of said partitions of said engaging member, and is connected with one contact of said light bulb, wherein another contact of said bulb is inserted into the other of said two partitions and electrically connected with said cathode, wherein said conducting strip has an end in contact with the other end of said coiled spring, another end of said conducting strip extending downwardly toward said nib end and having a protuberance near said other end in contact with an outer surface of said engaging member and forming means for engaging and disengaging said cathode upon rotation of said cap and shaft relative to one another, and wherein said spiral spring is arranged on a circular bulged portion within said shaft and has a second end which engages a bottom end of said reflector to bias said shank against said shield and said protruding portion of said shield against said actuating ring, such that rotation of said shield and actuating ring relative to each other cause engagement and disengagement of said ledge and protruding portion and consequent extension and retraction, respectively, of said nib, wherein by rotating said cap or said shaft, said bulb is lit when said protuberance contacts said cathode and said nib is extended ro retracted in response to engagement and disengagement of said ledge from said protruding portion of said shield, simultaneously or at different times depending on the relative rotational position of the cap and shaft.
