Abstract:
A hand tool for driving, and selectively illuminating through, a conventional socket, comprising:a) a handle; b) a shaft extending coaxially from said handle for engaging the conventional socket; c) illuminating apparatus operatively connected to said handle; and; d) a tip being square in lateral cross section for replaceably engaging in, rotating with, and driving, the conventional socket; wherein said handle is slender, elongated, and has: i) an hexagonal lateral cross section for facilitating gripping thereof; ii) a rearwardmost end; iii) a forwardmost end; and iv) a throughbore that extends longitudinally and centrally therethrough, from, and opens into, said rearwardmost end thereof, to, and opens into, said forwardmost end thereof; wherein said forwardmost end of said handle has a blindbore that extends longitudinally and centrally therein, and communicates with, and is coaxial with, but has a diameter greater than that of, said throughbore in said handle; wherein said rearwardmost end of said handle has a blindbore that extends longitudinally and centrally therein, is threaded, and communicates with, and is coaxial with, but has a diameter greater than that of, said throughbore in said handle; wherein said shaft is slender, elongated, flexible, and has: i) a rearwardmost end that is fixedly received in, and has a diameter as that of, said blindbore in said forwardmost end of said handle for rotation therewith; ii) a forwardmost end; and ii) a throughbore that extends longitudinally and centrally therethrough, from, and opens into, said rearwardmost end thereof, to, and opens into, said forwardmost end thereof, and communicates with, is collinear with, and has a diameter as that of, said throughbore in said handle; wherein said tip has: i) a rearwardmost end being coincident with, and extending coaxially from, said forwardmost end of said shaft for rotation therewith; ii) a forwardmost end; and iii) a throughbore that extends longitudinally and centrally therethrough, from, and opens into, said rearwardmost end thereof, to, and opens into, said forwardmost end thereof, and communicates with, is collinear with, and has a diameter as that of, said throughbore in said shaft; wherein said illuminating apparatus comprises: i) a fiber optic strand that extends coaxially and continuously in said throughbore in said handle, said throughbore in said shaft, and said throughbore in said tip, from, but not entering into, said blindbore in said rearwardmost end of said handle, to said forwardmost end of said tip; and ii) a module that is replaceably attached to said handle for holding a battery; wherein said module comprises a case that is slender, elongated, cylindrically-shaped for holding the battery, and has: i) a rearwardmost end; and ii) a forwardmost end that has a diameter less than that of said handle so as to avoid being gripped when said handle is gripped so as to be prevented from being broken off when attached to said handle; wherein said forwardmost end of said case has a throughbore that extends longitudinally and centrally therethrough; wherein said case contains a battery interface for electrically communicating with the battery contained therein; wherein said case further has a collar that extends coaxially from, and has a diameter less than that of, said forwardmost end of said case, and is threaded so as to threadably engage in, and have a diameter as that of, said blindbore in said rearwardmost end of said handle so as to attach said module to said handle; wherein said collar of said case has a throughbore that extends longitudinally and centrally therethrough, and communicates with, and is collinear with, said throughbore in said forwardmost end of said case and communicates with, and has a diameter as that of, said throughbore in said handle; and wherein said module further comprises: i) a light that sits in said throughbore in said forwardmost end of said case, electrically communicates with said battery interface in said case for powering thereby, and illuminates through said throughbore in said collar of said case and through said fiber optic strand for illuminating through the conventional socket; and ii) a dial switch that is disk-shaped, rotatably mounted to, is coaxial with, and has a diameter as that of, said rearwardmost end of said case, and electrically communicates with said battery interface so as to selectively illuminate said light when rotated accordingly.
