Abstract: An apparatus and method for operating a writing implement and an operating mechanism for the same. The writing implement has an extensible and retractable writing cartridge carried within a body of the writing implement. The operating mechanism includes an carrier for selectively extending a tip of the writing cartridge from the body. A release button is operable from each side of the body for releasing the carrier from a locked condition in which the writing cartridge is retained in the extended position and a release condition permitting retraction of the writing cartridge into the body. The operating mechanism includes a carrier with a recess to slidably receive the release button and a yoke spring to urge the release button to a centered position. In the locked position, a base of a first tab on the carrier is urged in subjacent abutment with a second tab on the release button.

Abstract: A bolt-action pen body is adapted as a universal receiver of an ink cartridge refill. The bolt action pen includes a hollow cylindrical pen body. A tip is removably coupled with an outer barrel at the distal end of the pen body. A refill cartridge is selectively extensible and retractable from the tip by a lever action movement of a bolt and a bolt carrier within a slot defined through a sidewall of the pen body. The bolt action pen provides for universal adjustment to various shapes of refill cartridges. An inner barrel is coupled with the pen body and is configured to adjust the pen body to a longitudinal length of the refill cartridge. A collet carried within the tip is configured for compressive adjustment to a diameter of writing end of the refill cartridge.

Abstract: A configurable leverage bit driver includes a first elongate shaft having a first bit receiving socket in an end face of the distal end. A second elongate shaft is dimensioned to couple with the first elongate shaft in a first axially aligned bit driving configuration. At least one aperture is defined in a lateral side of the second elongate shaft and is dimensioned to selective couple with the first elongate shaft to configure the first elongate shaft and the second elongate shaft in a second bit driving configuration with the second elongate shaft oriented as a lever arm aligned in a transverse axis to the longitudinal axis of the first elongate shaft. The second bit driving configuration may be one or more of a T-handle or an offset T-handle bit driver for increased leverage in driving a fastener.

Abstract: An improved multi-bit screwdriver tool that retains a plurality of screwdriver bits in a screwdriver tool handle. An actuator bar is operable to conveniently extend the plurality of bits from a lateral aspect of the screwdriver body to permit convenient selection of a desired bit from the plurality of bits. Once a desired bit is selected, the actuator bar is released to retract the bits in a stowed condition.
