Abstract

In a multi-tip stylus pen for a touch-screen device includes an elongated body member which may be capped with a hollow cap member. The hollow cap member has a first stylus tip member disposed at one of the cap ends without an opening. The first stylus tip member includes a first rounded tip of a material and shape suitable for contact with the touch-screen. The elongated body member has a second stylus tip member disposed at a first end. The second stylus tip member comprises a second stylus tip having a second rounded tip of a material and shape suitable for contact with the touch-screen. A third stylus tip member may be disposed at a second end of the body member. The third stylus tip comprises a third rounded tip of a material and shape suitable for contact with the touch-screen.

Claims

1. A multi-tip stylus pen for inputting information into a computing device through touching a touchscreen of the computing device comprising:

an elongated body member having a first end and a second end;

a hollow cap member comprising;

an inner cavity with an opening at a first end of the cap member configured to receive the second end of the body member; and

a first stylus tip member disposed at a second end of the cap member, the first stylus tip member comprising a first stylus tip, the first stylus tip comprising a first rounded tip of a material and a shape suitable for contact with the touchscreen;

a second stylus tip member disposed at the first end of the body member, the second stylus tip member comprising a second stylus tip, the second stylus tip comprising a second rounded tip of a material and shape suitable for contact with the touchscreen; and

a third stylus tip member disposed at a second end of the body member, the third stylus tip member comprising a third stylus tip, the third stylus tip comprising a third rounded tip of a material and shape suitable for contact with the touchscreen.

2. The stylus pen of claim 1, wherein the first rounded tip has a first base width greater than a second base width of the second rounded tip.

3. The stylus pen of claim 2, wherein the first rounded tip comprises a first hemispherical dome tip portion, the first dome tip portion having a first diameter substantially equal to the first base width, and a first cylindrical portion, the first cylindrical portion having the first diameter.

4. The stylus pen of claim 2, wherein the second rounded tip has a second base width greater than a third base width of the third rounded tip.

5. The stylus pen of claim 4, wherein the second rounded tip comprises a second hemispherical dome tip portion, the second dome tip portion having a second diameter substantially equal to the second base width, and a second cylindrical portion, the second cylindrical portion having the second diameter.

6. The stylus pen of claim 4, wherein the body member comprises an elongated cylindrical portion having a body diameter greater than the first base width.

7. The stylus pen of claim 4, wherein the hollow cap member is configured to receive the first end of the body member.

8. The stylus pen of claim 1, wherein any one of the first, second, and third stylus tips are coupled to the body member through an electrically conductive removable link member.

9. The stylus pen of claim 1, wherein the first stylus tip has a first diameter between 6.5 mm and 9 mm.

10. The stylus pen of claim 9, wherein the second stylus tip has a second diameter between 5.5 mm and 6.5 mm.

11. The stylus pen of claim 10, wherein the third stylus has a third diameter between 1.0 mm and 5.5 mm.

12. The stylus pen of claim 1, wherein at least one of the first stylus tip, the second stylus tip, or the third stylus tip comprises a hollow cavity enclosed therein and a cavity wall having a cavity wall thickness.

13. The stylus pen of claim 12, wherein the at least one of the first, second, and third stylus tips comprise an elastomeric material, the elastomeric material designed to deform in a direction parallel to an axis of elongation of the body member towards the touch screen by an amount proportional to an amount of force applied in the elongate direction.

14. The stylus pen of claim 13, wherein the elastomeric material comprises a silicone-based material.

15. The stylus pen of claim 13, wherein the elastomeric material comprises a rubber-based material.

16. The stylus pen of claim 13, wherein the cavity wall thickness is between 0.3 mm and 0.8 mm.

17. The stylus pen of claim 16, wherein the at least one of the first, second, and third stylus tips have a resistivity between 0.01 and 1 Ohms.

18. The stylus pen of claim 1, wherein any one of the first, second, and third rounded tips have at least one cross section having a shape chosen from a group consisting of a circle, an oval, a triangle, rectangle, a pentagon, a hexagon, an octagon, and a diamond.

19. The stylus pen of claim 1, wherein the body member has at least one cross section area having a shape chosen from a group consisting of a circle, an oval, a triangle, rectangle, a pentagon, a hexagon, an octagon, and a diamond.

20. The stylus pen of claim 1, wherein the cap member has a length sufficient to cover at least one third of the body member.

21. The stylus pen of claim 1, wherein the cap member further comprises an elastic clip configured to attach the cap member to a sheet or a shirt pocket.

22. A multi-tip stylus pen for inputting information into a computing device through touching a touchscreen of the computing device comprising:

an elongated body member having a first end and a second end;

a hollow cap member comprising;

an inner cavity with an opening at a first end of the cap member configured to receive the second end of the body member; and

a first stylus tip member disposed at a second end of the cap member, the first stylus tip member comprising a first stylus tip, the first stylus tip comprising a first rounded tip of a material and shape suitable for contact with the touchscreen;

a second stylus tip member disposed at the first end of the body member, the second stylus tip member comprising a second stylus tip, the second stylus tip comprising a second rounded tip of a material and shape suitable for contact with the touchscreen; and

23. The stylus pen of claim 22, further comprising a writing member disposed at a second end of the body member, the writing member comprising writing tip suitable for writing on a writing surface.

24. The stylus pen of claim 23, wherein the writing tip is a ball point tip.
