Abstract

An hand held elongated implement with a retractable tip at one end and a stylus point at the opposite end. The implement incorporates a retraction and extension means by which pressure need not be applied to the stylus tip for actuation but rather, retraction or extension is accomplished by the application of generally downward force upon the sloping sides of the implement proximate the stylus end. The implement may further include a clip which serves many purposes, including the providing of a curved surface on which said downward force may be comfortably applied and the providing of a contoured surface upon which the user may comfortably rest their thumb or forefinger when the implement is used in its inverted position as a stylus point instrument.

Claims

1. A retractable tip hand held implement having an elongated implement body, an implement tip end, a stylus end and a retraction means;

said stylus end having a generally conical shape terminating in a point located at the end of the body opposite the implement tip end; and

said retraction means capable of being actuated by the application of a generally downward axial force upon the conical sides of the stylus end proximate the point.

2. The implement of claim 1 whereby the retraction means further comprises a spring located radially outside of an elongated implement body.

3. The implement of claim 1, wherein said hand-held implement is selected from the group consisting of a writing instrument, a laser pointer, a multi-function writing instrument, a screwdriver, and a tire pressure gauge.

4. The hand held implement of claim 1 further including a writing tip which is selected from the group consisting of:

ink pen, pencil, highlighter and marker.

5. The hand held implement of claim 1, whereby at least one of the implement tip and stylus ends further comprises a cushioned grip surface.

6. The hand held implement of claim 1, wherein graphical or advertising material is imprinted on at least one surface for the purpose of providing advertising or promotion.

7. The hand held implement of claim 1 whereby the implement further comprises at least one contoured clip attached to the implement body.

8. The hand held implement of claim 7 whereby the clip is contoured and curved such that the user'"'"'s thumb may rest on an inwardly curved portion of the clip outer surface when using the stylus point end of the implement.

9. The hand held implement of claim 7 whereby the clip is contoured and curved such that the user'"'"'s thumb may press upon an inwardly curved portion of the clip outer surface to serve as a point of application of downward axial pressure on the stylus end to actuate the retraction or extension of the implement tip.

10. A hand held implement comprising a first end, a second end, a body, a retraction mechanism and a clip;

said first end being an elongated barrel shape and having an orifice through which a writing tip may extend and retract with the inboard end of the writing tip affixed to a writing media refill cartridge;

said second end being an elongated shape terminating at a stylus point positioned opposite the first end orifice in the assembled implement;

said body having a generally tubular shape in which a media refill cartridge may reside and translate axially as the writing tip is extended or retracted;

said retraction mechanism including a spring radially displaced externally to the body and surrounding an attachment point of one end to the body, and serving to extend or alternatively retract said media shaft and writing tip by means of a spring loaded retraction mechanism, actuated by an application of axial compressive force upon the second end proximate to but not upon the stylus tip; and

said clip comprising a contoured outer surface which is curved such that the user'"'"'s thumb may rest upon an inwardly curved portion of said outer surface when using the stylus end of the implement.

11. The hand held implement of claim 10 whereby the writing tip is selected from the group consisting of:

ink pen, pencil, highlighter, marker, laser pointer.

12. The hand held implement of claim 10, whereby at least one of the first and second ends further comprises a cushioned grip surface.

13. The hand held implement is claim 10, whereby at least one of the first end and the second end is attached to the body by coaxial threaded connection.

14. The hand held tip of claim 10, wherein graphical or advertising material is imprinted on at least one surface for the purpose of providing advertising or promotion.

15. A method of advertising or promotion whereby graphical or advertising material is imprinted on at least one surface of a hand held implement hand held implement having a first end, a second end, a body, a retraction mechanism and a clip;

said first end being an elongated barrel shape and having an orifice through which a writing tip may extend and retract with the inboard end of the writing tip affixed to a writing media refill cartridge;

said second end being an elongated shape terminating at a stylus point positioned opposite the first end orifice in the assembled implement;

said body having a generally tubular shape in which a media refill cartridge may reside and translate axially as the writing tip is extended or retracted;

said retraction mechanism including a spring radially displaced externally to the body and surrounding an attachment point of one end to the body, and serving to extend or alternatively retract said media shaft and writing tip by means of a spring loaded retraction mechanism, actuated by an application of axial compressive force upon the second end proximate to but not upon the stylus tip; and

said clip comprising a contoured outer surface which is curved such that the user'"'"'s thumb may rest upon an inwardly curved portion of said outer surface when using the stylus end of the implement.
