Abstract
A writing utensil such as a pen having multiple magnetic members along its barrel. The magnetic members have opposite polarity so as to drive each other away. One of the magnetic members may be bonded to the barrel while the other extends around it to form a ring with an inner circumference large to allow it to move along the barrel between the bonded magnetic member and a capturing mechanism at a top end of the barrel. The capturing mechanism may have a metal member to retain the floating magnetic member for temporary storage.
Claims20
A writing utensil comprising:
- a barrel having a writing end, a distal end opposite the writing end, and a body in between the writing end and the distal end;
- a capturing mechanism fixedly attached to the barrel proximate the distal end;
- a first magnetic member fixed to a point along the body between the capturing mechanism and the writing end such that the distance between the first magnetic member and the writing end is constant, the first magnetic member having a first polarity;
- a second magnetic member along the body between the capturing mechanism and the first magnetic member, the second magnetic member having a second polarity;
- wherein the first polarity is opposite the second polarity.

A writing utensil comprising:
- a barrel having a writing end and a distal end opposite the writing end;
- a cylindrical body portion of the barrel in between the distal end and the writing end, the cylindrical body portion having an upper portion proximate the distal end of the barrel with a first circumference and a lower portion proximate the writing end of the barrel with a second circumference that is
- greater than the first circumference;
- and
- a first annular magnetic member having a first polarity and an inner circumference that is greater than the first circumference but less than the second circumference, the first annular member positioned around the upper portion of the body portion of the barrel;
- and
- a second magnetic member having a second polarity that is opposite the first polarity, the second magnetic member positioned along the body portion between the first magnetic member and the writing end of the barrel.
4 more elements
A writing utensil comprising:
- a writing end;
- a distal end opposite the writing end;
- an elongate body separating the writing end and the distal end;
- a first magnetic member along the body having a first polarity;
- a second magnetic member along the body between the first magnetic member and the distal end, the second magnetic member having a second polarity opposite the first polarity;
- and
- a capturing member fixed to the body at a point between the second magnetic member and the distal end;
- wherein at least one of the first magnetic member or the second magnetic member is configured to travel along at least a portion of an outer surface of the elongate body.
