Abstract

A marker pen has a marker tip at one end and a reservoir for marker fluid adjacent the other end. The pen is pivoted between the marker tip and the reservoir to one end of a support arm for pivotal movement from a position of use to a stored position. In the position of use, the support arm rests between the thumb and index finger of the user and the reservoir extends upwardly above the marker tip. In the stored position, the reservoir extends alongside the support arm.

Claims2

Dependent claims

A marker pen assembly comprising

an elongated pen member having an inner end portion provided with a marker tip on a free end of said inner end portion,
said pen member having an elongated barrel-shaped outer end portion defining a chamber providing a reservoir for marker fluid,
said pen member having passage means for conducting a flow of the marker fluid from the reservoir to the marker tip,
an elongated support arm member for the pen member,
pivot means connecting the pen member to one end of the support arm member at a point between the inner and outer end portions of the pen member for pivotal movement of the pen member from a first position of use to a second position for storage, and
means for releasably locking said pen member selectively in said first position and in said second position,
said outer end portion of the pen member extending alongside the arm member in parallel relationship to the arm member when said pen member is in the second position for storage,
the outer end portion of the pen member extending upwardly from the support arm member in a position such that the reservoir is above the marker tip when the pen member is in the first position of use and the marker pen assembly is held in a hand of a user with the support arm member resting in the hand between a thumb and an index finger of the hand and the marker tip extends forwardly for marking,
said means for releasably locking said pen member comprising a detent carried by one of said members and recesses in the other of said members selectively engaged by said detent in the respective first and second positions of said pen member,
wherein the inner end portion of the pen member is disposed at an obtuse angle to the outer end portion of the pen member, and the inner end portion of the pen member extends in straight line continuation of the arm member and coincides with a central axis of said arm member when the pen member is in the first position of use.
