Description of the Related Art
Currently, there are many smart electronic devices accessorized with touch screen styli to enable users to write or sketch accurately on the touch screens. Generally, such a touch screen stylus comprises a sharp tip with an elongated pencil-shaped body. Some of the styli also have an extra antenna or flash drive integrated within in it. Moreover, the smart device companies currently in the market are paying increasing attention to the aesthetical design of touch screen styli.
The sharp tip of a stylus can be fragile, if the tip impacts the floor after being dropped. An elongated body may result in the stylus easily being bent. Furthermore, the patterns or special paint on the stylus surface may need protection against scratches from daily uses. However, to date very few of the styli are designed to be sturdy and scratch proof to preserve the look and functionality for long-term use.
Therefore, there is a recognized need in the art for a protection sheath that can protect both the tip and the body of a touch screen stylus. Particularly, the prior art is deficient in this aspect. The present invention fulfills this long-standing need and desire in the art.
The present invention is directed to a protection sheath for a touchscreen stylus. The protection sheath comprises a top portion disposed around a top section of the stylus and 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. The present invention is directed to a related protection sheath that further comprises means for storing a stylus cap thereon.
The present invention also is directed to a sheath for a stylus. The sheath comprises a top portion disposed around a top end of the stylus and a bottom portion is disposed around a bottom end of the stylus. A position-limiting ring has a bottom section having 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 the middle section. A tightening structure comprises 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 is disposed in the bottom portion of the sheath below the tightening structure. A stop clip is disposed through the side of the top portion of the sheath. A motion stop disposed on a side surface of the tightening structure is configured to removably receive said stop clip.
The present invention is directed further to a stylus sheath for protecting a touch screen stylus comprising a top portion disposed around a top end of a stylus. The top portion comprises 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 is disposed around a bottom end of a stylus. The bottom portion comprises a distal end with threads disposed on an outer surface thereof. The threads are engaged with the threads at the proximal end of the top portion. A securing top comprises a proximal end with threads disposed on an outer surface thereof. The threads are engaged to the threads of the distal end of the top portion. A damper band is 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 the damper band.
