Flexible socket extension

Claim 1

A flexible extension tool comprising: (a) a hollow helically wound flexible cable; (b) a pair of end caps wherein one of said end caps is operatively attached to one end of said flexible cable and the other of said end caps is attached to the other end of said flexible cable and wherein one end cap has an opening therein colinear with the interior of said flexible cable; (c) a plurality of essentially identical, torque transmitting elements within said flexible cable wherein each of said elements consists of a cylindrical cross-sectional element with curved surface and centrally positioned radial groove means at one end and an orthogonal centrally positioned radially curved tongue means at the other end wherein said tongue means is adapted to operatively fit into said groove means thus completing a flexible sequence of torque transmitting elements free of any attachment linkage; (d) a plurality of plastic ring spacer means, wherein each of said plurality of torque transmitting elements contain at least one of said plastic ring spacer means externally surrounding and radially extending beyond said cylindrical cross-sectional element such as to partially occupy the annular space between said hollow helically wound flexible cable and said torque transmitting elements such as to allow smooth, low friction transmission of applied torque; (e) a female connector means passing through the opening in one of said end caps and operatively engaged to said flexible sequence of torque transmitting elements within said flexible cable and wherein said female connector is adapted to engage to and be driven by a conventional ratchet wrench; and (f) a male connector means passing through the opening in the other of said end caps and operatively engaged to the other end of said flexible sequence of torque transmitting elements within said flexible cable and wherein said male connector is adapted to engage to and drive a conventional socket.
