Two-piece magnetically actuated pen
First Claim
1. A magnetically actuated writing instrument comprisinga holder portion including a first magnetically attractive member, anda writing instrument portion having an interior and a second magnetically attractive member, the writing instrument portion including a barrel having a distal end portion, the barrel being movable between a retracted position wherein the distal end portion is disposed within the interior of the writing instrument portion, and an extended position wherein the distal end portion is disposed exteriorly of the writing instrument portion, anda retractor for moving the barrel between the retracted and extended positions, the retractor including the first and second magnetically attractive members, and a locking latch member for locking the barrel in an extended position wherein the barrel is prevented from moving to the retracted position,wherein the presence of magnetic attraction between the first magnetically attractive member and the second magnetically attractive member causes the barrel to move toward the retracted position, and the absence of magnetic attraction between the first and second magnetically attractive members causes the barrel to move toward the extended position.

Abstract
A magnetically actuated writing instrument includes a holder portion including a first magnetically attractive member. The instrument also includes a writing instrument portion having an interior and a second magnetically attractive member. The writing instrument portion includes a barrel having a distal end portion. The barrel member is movable between a retracted position wherein the distal end is disposed within the interior of the writing instrument portion, and an extended position wherein the distal portion is disposed exteriorly of the writing instrument portion. A retractor for moving the barrel between the retracted and extended positions includes the first and second magnetically attractive members. The presence of magnetic attraction between the first magnetically attractive member and the second magnetically attractive member causes the barrel to move toward the retracted position, and the absence of magnetic attraction between the first and second magnetically attractive members causes the barrel to move toward the extended position.

19. A magnetically actuated writing instrument comprising
a holder portion including a first magnetically attractive member, and a writing instrument portion having an interior and a second magnetically attractive member, the writing instrument including a barrel having a distal end portion, the barrel being movable between a retracted position wherein the distal end is disposed within the interior of the writing instrument portion, and an extended position wherein the distal portion is disposed exteriorly of the writing instrument portion, and a retractor for moving the barrel between the retracted and extended positions, the retractor including: -
the first and second magnetically attractive members, a locking member for locking the barrel in the extended position a retractor housing having an interior, and a base portion coupled to the retractor housing, and wherein the locking member is coupled to the base portion wherein the second magnetically attractive member is coupled to the retractor housing, wherein the locking member includes at least one latch member disposed within the interior of the retractor housing, the retractor housing includes a first aperture, the latch member being radially movable for being extendable through the first aperture, and wherein the presence of magnetic attraction between the first magnetically attractive member and the second magnetically attractive member causes the barrel to move toward the retracted position, and the absence of magnetic attraction between the first and second magnetically attractive members causes the barrel to move toward the extended position. - View Dependent Claims (20, 21)
