Intro

Today's touch-screen pens create a dry friction effect that results in less efficient and less comfortable writing and sketching. The method described in this patent application could be the solution for this technical problem. It uses a tip arrangement for a touch-screen pen, comprising a ball intended as the contact surface with the touch-screen and a supporting element, which creates a magnetic interaction. Because of the magnetic interaction the ball of the tip arrangement is capable of easily rolling across the touch-screen display creating a sensorial feedback similar to the one you would get when you use a ballpoint pen on a piece of paper.

Claims

1. Tip arrangement (3) for pen for electronic touch-screen device, comprising a ball (4) intended for contacting the touch-screen and a supporting ele...
  1. Tip arrangement (3) for pen for electronic touch-screen device, comprising a ball (4) intended for contacting the touch-screen and a supporting element (5) combined with said ball (4), characterized in that interaction of magnetic attraction is caused between said ball (4) and said supporting element (5).
  2. Tip arrangement according to claim 1, wherein said supporting element (5) is at least partially made of an electrically conductive material, wherein said supporting element preferably is a magnetic dipole, permanent magnet or electromagnet.
  3. Tip arrangement according to claim 1 or 2, wherein said supporting element (5) has circular section.
  4. Tip arrangement according to any one of the preceding claims, wherein said supporting element (5) comprises a proximal surface (6) in contact with said ball (4), wherein said proximal surface (6) preferably is a flat surface.
  5. Tip arrangement according to any of the preceding claims, wherein said ball (4) is at least partially made of an electrically conductive material, more preferably a metal material having magnetic, ferromagnetic or paramagnetic properties.
  6. Tip arrangement according to claim 4 or 5, wherein said ball (4) has an outer surface comprising at least two zones (7, 8) developing two respective coefficients of dynamic rolling friction, said coefficients being different from one another and measured between each of said two zones and said proximal surface (6) of said supporting element (5).
  7. Tip arrangement according to claim 6, wherein said at least two zones comprises a first zone (7) proximal to said supporting element (5), and a second zone (8) distal from said supporting element (5), and a second zone (8) distal from said supporting element (5), wherein said coefficient of dynamic rolling friction between said first zone (7) and said proximal surface (6) of the supporting element (5) is lower than said coefficient of dynamic rolling friction between said second zone (8) and said proximal surface (6) of the supporting element (5).
  8. Tip arrangement according to claim 7, wherein said second zone (8) extends for at least half of said outer surface of said ball (4), preferably wherein said second zone (8) extends for at least 60 % of said outer surface of said ball (4).
  9. Tip arrangement according to claim 7 or 8, comprising a covering layer extended on a portion of said ball (4) and delimiting said second zone (8), wherein said covering layer is constituted by or comprises a material having high friction coefficient.
  10. Tip arrangement according to any one of claims 6 - 8, wherein said at least two zones (7, 8) are obtained by: a chemical treatment and/or a machining of at least one portion of said outer surface of said ball (4); and/or by assembling materials different from one another to make said ball (4).
  11. Tip arrangement according to any one of claims 4 - 10, comprising a covering layer extended on said first zone (7) of said ball (4) and/or on said proximal surface (6) of said supporting element (5), wherein said covering layer is constituted by or comprises a material having a low friction coefficient.
  12. Pen (1) for an electronic touch-screen device, comprising an elongated body (2) and a tip arrangement (3) according to any one of the preceding claims, wherein said tip arrangement (3) is combined with said body (2), in case in a removably way.
  13. Pen according to claim 12, wherein said magnetic attraction interaction has variable intensity and can be adjusted by the user.
  14. Kit comprising a pen according to claim 12 or 13, and a plurality of balls (4a, 4b) with diameters different from one another and/or which comprise at least two zones with different friction properties.

This is a great idea, pens for touch pads suck because of the drag.
Applications: Individual, multi packs, and key ring for touch screen devices.
Companies: All manufactures of touch screen devices, all software art applications. State and federal agencies using sign touch screen pads S well as the manufactures of touch screen signiture devices like the post office, pharamacy,and DMV
