Embodiment Construction

[0030] figure 1 An embodiment of a writing instrument 1 having a refill base mechanism 2 formed in accordance with the principles of the present invention is shown. Writing instrument 1 comprises a substantially hollow housing 3 comprising a lower part 4 and an upper part 5 . The lower part 4 has a generally tapered end 11 at the end terminating in an aperture 30 through which the refill cartridge 6 can protrude, and a connecting end 40 opposite the tapered end 11 . The upper part 5 has a connecting end 42 at one extremity and, opposite the connecting end 42 , a closed end 44 terminating in the end cap 12 . The end cap 12 may be a separate component attached to or inserted into the closed end 44 , or the end cap 12 may be formed as part of the closed end 44 . In the embodiment shown, the lower and upper parts 4, 5 can be rotatably connected by means of threaded connections at the connection ends 40, 42 of the lower and upper parts 4, 5, respectively. It will be appreciated ...

Abstract

An automatically-adjusting seat mechanism is disclosed for automatically adjusting the chamber length in a writing instrument to accommodate refills of different lengths. The mechanism comprises a first element and a second element operably engaged with the first element. When contacted by a refill, the second element automatically moves from a first position associated with a first chamber length to a second position associated with a second chamber length. The mechanism may have a biasing member to releasably hold the second element in the first position. Other embodiments include a third element and a third chamber length. A method of using the automatically-adjusting refill seat mechanism is also disclosed.

Description

technical field [0001] The present invention relates generally to writing instruments, and more particularly, to a writing instrument having a base that automatically adjusts to accept refills of different lengths. Background technique [0002] It is not uncommon for pen manufacturers to make refill cartridges that differ in diameter and length from their competitors' pens. Manufacturers each typically make the elongated inner cavity of the pen case enclosing the refill cartridge a unique length to match the length of their own brand of refills. Therefore, the base of the reloading cartridge barrel against which the non-writing end of the refilling refill abuts is in a fixed position relative to the pen shell, thereby determining the length of the refilling refill chamber. This practice often prevents consumers from using one manufacturer's refill cartridges in other manufacturer's pens because the writing tip of the refill cartridge (which delivers ink) does not protrude f...
