Protection Sheath for a Touch Screen Stylus

Abstract

Provided herein are protection sheaths or stylus sheaths for a touch screen stylus. Generally, the protection sheath has top and bottom portions disposed around stylus and means for moving the stylus inside the protection sheath. A position-limiting ring and a tightening structure with a spring disposed on the top of the position-limiting ring may comprise the means by which to extend and to retract the stylus tip. The sheath may have a stop clip disposed through the top portion which works with a motion stop on the tightening structure to limit the motion of the stylus. Alternatively, the top and bottom portions may be threaded and the sheath may have a securing top and damper band to secure the stylus within the sheath.

What is claimed is: 
     
         1 . A protection sheath for a touch screen stylus, comprising:
 a top portion disposed around a top section of the stylus;   a bottom portion disposed around a bottom section of the stylus in a connecting relationship with said top portion; and   means for moving the stylus inside the protection sheath.   
     
     
         2 . The protection sheath of  claim 1 , wherein said stylus comprises a cap disposed on a distal end thereof, said protection sheath further comprising means for storing the cap thereon. 
     
     
         3 . The protection sheath of  claim 2 , wherein said storing means comprises a pen clip disposed on the top portion of the sheath configured to secure said stylus cap on the top thereof. 
     
     
         4 . The protection sheath of  claim 1 , wherein said top portion and said bottom portion are each substantially cylindrical. 
     
     
         5 . The protection sheath of  claim 1 , wherein each of said top portion and said bottom portion are hollow and each comprises an opening at top and bottom ends thereof. 
     
     
         6 . The protection sheath of  claim 1 , wherein said moving means comprises:
 a position limiting ring having a bottom clip that fits into a top opening of the clip at the bottom of the sheath, a threaded head and a position-limiting button disposed on an inner surface of the threaded head;   a tightening structure comprising an exteriorly threaded top end having a clip formed thereon and a bottom end having a spiral groove disposed on an outer surface thereof configured to slidably receive the position-limiting button, said bottom end inserted into a top opening of the position-limiting ring; and   a sleeve nut threadably engaging the threaded top of the tightening structure.   
     
     
         7 . The protection sheath of  claim 6 , wherein the position-limiting ring rotably engages the stylus in an upward and downward motion, said motion limited by the position of the position-limiting button in the spiral groove 
     
     
         8 . The protection sheath of  claim 6 , wherein the top portion of the protection sheath threadably engages the threaded head of the position-limiting ring. 
     
     
         9 . A protection sheath for a touch screen stylus, comprising:
 a top portion disposed around a top end of the stylus;   a bottom portion disposed around a bottom end of the stylus;   a position limiting ring having a bottom section comprising a clip that fits into a top opening of the bottom portion of the sheath, a ring-like middle section, and a top section comprising a threaded head on top of said middle section;   a tightening structure comprising an exteriorly threaded top end having a clip formed thereon and a bottom end insertable into the threaded head of the position-limiting ring;   a spring disposed in the bottom portion of the sheath below the bottom end of the tightening structure;   a stop clip disposed through the side of the top portion of the protection sheath; and   a motion stop disposed on a side surface of the tightening structure configured to removably receive said stop clip.   
     
     
         10 . The protection sheath of  claim 9 , wherein said spring is configured to push said tightening structure upwards when said stop clip is lifted from the motion stop thereon. 
     
     
         11 . The protection sheath of  claim 9 , wherein said top portion and said bottom portion are each substantially cylindrical. 
     
     
         12 . The protection sheath of  claim 9 , wherein each of said top portion and said bottom portion are hollow and each comprises an opening at proximal and distal ends thereof. 
     
     
         13 . The protection sheath of  claim 9 , wherein the top portion of the protection sheath is threadable around the threaded head of the position-limiting ring. 
     
     
         14 . A stylus sheath for protecting a touch screen stylus, comprising:
 a top portion disposed around a top end of a stylus, comprising a proximal end with threads disposed on an inner surface thereof and a distal end with threads disposed on an inner surface thereof;   a bottom portion disposed around a bottom end of a stylus, comprising a distal end with threads disposed on an outer surface thereof, said threads engaged with the threads at the proximal end of the top portion; and   a securing top comprising a proximal end with threads disposed on an outer surface thereof, said threads engaged to the threads of the distal end of the top portion; and   a damper band disposed over the threads of the distal end of the top portion configured to secure the stylus in the sheath when the securing top is screwed into the top portion and pressed against said damper band.   
     
     
         15 . The stylus sheath of  claim 14 , further comprising a pen clip having a ring and a clip body perpendicularly connected to said ring, said ring secured between the securing top and the top portion thereof, configured to store a stylus cap. 
     
     
         16 . The stylus sheath of  claim 14 , wherein said top portion, bottom portion and securing top are substantially cylindrical. 
     
     
         17 . The protection sheath of  claim 14 , wherein said damper band comprises rubber, silicon, plastic or a combination thereof.
