Patent ID: 7104196

Claim:
A rolling marker assembly, the rolling marker assembly for enabling a user to mark serially-presented, repeating patterns upon a marking surface, the rolling marker assembly comprising a hand-holdable casing and a caster assembly, the casing comprising an inner casing surface, an outer casing surface, a substantially circular transverse casing cross-section, a longitudinal casing axis, a casing height, and a casing rim, the caster assembly comprising a marker carriage, a rotating pen assembly, and a caster assembly length, the marker carriage comprising a casing attachment member and pen assembly-receiving means, the pen assembly comprising an inner pen core, a plurality of intermediate ink-dispensing pads, a plurality of outer ink-masking shells, and at least one marker rotation axis, the inner pen core having a centroid, the ink-masking shells each comprising a patterned aperture and an outer shell surface, each ink-dispensing pad being impregnated with compression-releasable ink, the rotating pen assembly being rotatably received by the marker carriage via the pen assembly-receiving means, the pen assembly being rotatable about the marker rotation axis, the caster assembly being rotatably attached to the casing, the caster assembly being rotatable about the casing axis, the ink-dispensing pads being compressibly sandwiched intermediate the ink-masking shells and the pen core, the ink-dispensing pads comprising pattern-exposed portions, the pattern-exposed portions extending through the patterned apertures, the pattern-exposed portions comprising a substantially uniform exposed pad thickness, the difference between the caster assembly length and the exposed pad thickness being substantially equal to the casing height, the casing rim and the outer shell surfaces being manually traceable adjacent a marking surface, the pattern-exposed portions being compressible upon the marking surface for dispensing ink therefrom, the rolling marker assembly thus enabling the user to mark serially-presented, repeating patterns upon the marking surface.
