Abstract
An example stylus pen including a body includes a central axis, a first end, and a second end. In addition, the stylus pen includes an engagement tip disposed at the first end and including resilient cover. Further, the stylus pen includes an adjustment mechanism at least partially disposed within the body and arranged such that manipulation of the adjustment mechanism by a user causes the cover of the engagement tip to actuate between a first shape and a second shape. The cover of the engagement tip is arranged to engage with a touch sensitive surface to cause a change in a computing device when in either one of the first shape and the second shape.
Claims20
A stylus pen comprising:
- a body including a central axis, a first end, and a second end;
- an engagement tip disposed at the first end and including resilient cover;
- and
- an adjustment mechanism at least partially disposed within the body and arranged such that manipulation of the adjustment mechanism by a user causes the cover of the engagement tip to actuate between a first shape and a second shape;
- wherein the adjustment mechanism comprises a barrel with a helical groove around an outer surface of the barrel, the adjustment mechanism further comprising a coil engaging the helical groove of the body;
- wherein the adjustment mechanism further comprises an extension member to engage the cover such that the cover assumes the first shape or the second shape based on position of the extension member relative to the resilient cover, the extension member mechanically engaged with the barrel.
A mechanism for controlling a shape of an engagement tip of a stylus pen, the mechanism comprising:
- the engagement tip disposed at a first end of the mechanism to engage with a resilient cover;
- and
- an adjustment mechanism arranged such that manipulation of the adjustment mechanism by a user causes axial movement of an extension member into or out of the cover of the engagement tip to actuate through a range of shapes between a first shape and a second shape;
- wherein the adjustment mechanism comprises a barrel with a helical groove around an outer surface of the barrel, the adjustment mechanism further comprising a coil engaging the helical groove of the body;
- wherein the extension member engages the barrel, wherein the cover assumes the first shape, the second shape or a shape between the first and second shapes based on rotation of the barrel to reposition the extension member relative to the resilient cover.
