Abstract
A writing instrument includes a nose section that is releasably connected to a barrel housing portion that contains an ink reservoir, in the form of a replaceable cartridge, for holding ink for delivery to a writing nib. The nose section is releasably connected to the barrel housing portion with a magnetic-mechanical connection assembly to allow easy access to the replaceable cartridge.
Claims20
An instrument comprising:
- a nose section having a hollow channel and a first opening at one end of the hollow channel;
- a barrel housing portion having an interior, the nose section being at least partially disposed within the interior of the barrel housing portion;
- and
- a magnetic-mechanical connection assembly between the nose section and the barrel housing portion that provides magnetic and mechanical force to secure the nose section to the barrel housing portion, the magnetic-mechanical connection assembly including at least one bayonet pin disposed on one of the nose section and the barrel housing portion and at least one locking channel disposed on the other of the nose section and the barrel housing portion.

A writing instrument comprising:
- a nose section having an opening at one end;
- a writing nib extending through the opening;
- a barrel housing portion connected to the nose section opposite of the writing nib, the barrel housing portion having an ink reservoir for holding ink to be delivered to the writing nib;
- and
- a magnetic-mechanical connection assembly that provides connection force for releasably connecting the nose section to the barrel housing portion;
- wherein the magnetic-mechanical connection assembly includes at least one nose magnet disposed on the nose section, at least one barrel housing magnet disposed on the barrel housing portion, at least one locking channel formed in an inner surface of the barrel housing portion, and at least one bayonet pin formed on an outer surface of the nose section, the bayonet pin being sized and shaped to fit within the locking channel to mechanically secure the nose section to the barrel housing portion, such that the barrel housing magnets and the nose magnets are aligned to provide an attractive force therebetween.
