Abstract
A writing instrument includes a nose section that is connected to a barrel housing portion that contains an ink reservoir for holding ink for delivery to a writing nib. A cap may be releasably secured to the barrel housing portion with a first magnetic-mechanical connection assembly to cover the nib to protect the nib from damage and to prevent ink evaporation. Similarly, the nose section may be releasably secured to the barrel housing portion with a second magnetic-mechanical connection assembly for accessing a replaceable ink cartridge that includes the ink reservoir.
Claims25
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, the nose section being releasably connected to the barrel housing portion opposite the first opening;
- a cap releasably attached to the barrel housing portion to enclose the opening;
- a first magnetic-mechanical connection assembly between the cap and the barrel housing portion that provides magnetic and mechanical force to secure the cap to the barrel housing portion;
- and
- a second 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.
A writing instrument comprising:
- a nose section having an opening at one end;
- a writing nib extending through the opening;
- a barrel housing portion releasably 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;
- a cap releasably connected to the barrel housing portion, the cap protecting the nib from damage;
- and
- a first magnetic-mechanical connection assembly that provides connection force for releasably connecting the cap to the barrel housing portion;
- and
- a second magnetic-mechanical connection assembly that provides connection force for releasably connecting the barrel housing portion to the nose section,
- wherein the first magnetic-mechanical connection assembly includes at least one barrel housing magnet disposed on the barrel housing portion, at least one cap magnet disposed on the cap, at least one outer locking channel formed in an outer surface of the barrel housing portion, and at least one cap bayonet pin formed on an inner surface of the cap, the cap bayonet pin being sized and shaped to fit within the outer locking channel to mechanically secure the cap to the barrel housing portion such that the at least one barrel housing magnet and the at least one cap magnet are aligned to provide an attractive force therebetween, and
- wherein the second magnetic-mechanical connection assembly includes at least one nose magnet disposed on an outer surface of the nose section, at least one nose bayonet pin disposed on an outer surface of the nose section, and at least one inner locking channel disposed on an inner surface of the barrel housing portion, the nose bayonet pin being sized and shaped to fit within the inner locking channel to mechanically secure the nose section to the barrel housing portion, such that the at least one nose magnet and the at least one barrel housing magnet are aligned to provide an attractive force therebetween.
