US 6,547,470 B2 · Retractable combination pen and screwdriver

Abstract

A combination tool capable of being clipped into a pocket which incorporates an outwardly biased writing implement, e.g., pen, into a tip of a removable Phillips-head screwdriver tip at one end of a hexagonal tube while having a removable second tip, e.g., regular screwdriver tip at an opposed end. The handle, an inwardly biased clip affixed thereto for fastening into a shirt or pant pocket, is used for facilitating rotational movement of the hexagonal tube with screw tips attached, and is insertable over either tip and at least partially onto the hexagonal tube, an interior hole within the handle being dimensioned so as to permit sliding frictional engagement between the handle and the tube. In a preferred embodiment, the pen has a selectively retractable tip, retracting effected by converting inward radial force into compressive longitudinal movement.

A tool which comprises:

(a) a tubular housing having a central bore and two ends;
(b) a flat head screwdriver tip for mating engagement at one end and a cross head screwdriver tip at the opposite end, the cross head screwdriver tip has a centrally disposed bore therethrough;
(c) a writing means disposed within the bore of said cross head tip;
and
(d) a biasing means within said housing bore exerting a predetermined longitudinal peripheral biasing force to said writing means, such that upon the application of an opposing force which exceeds said predetermined longitudinal peripheral biasing force, said writing means is retracted into said cross head tip.
