Bobbin

摘要

A bobbin includes an anti-rolling unit capable of supporting the bobbin to prevent the bobbin from rolling on a floor. The bobbin includes a cylindrical part around which a wire is wound, flanges provided at left and right sides of the cylindrical part, a through hole defined through a central portion of the cylindrical part and central portions of the left and right flanges, a handle part including a pair of support shafts, which protrude so as to be fitted into the through hole from left and right flanges, and left and right support rods having end portions fixed to the support shafts, respectively, and extending in parallel to the left and right flanges while making contact with outer surfaces of the right and left flanges, and an anti-rolling unit for the bobbin.

1. A bobbin comprising:
a cylindrical part around which a wire is wound; flanges provided at left and right sides of the cylindrical part, having diameters greater than a diameter of the cylindrical part, and having a plate shape; a through hole defined through a central portion of the cylindrical part and central portions of the left and right flanges; a handle part having a substantially “” shape and including a pair of support shafts, which protrude so as to be fitted into the through hole from left and right flanges, and left and right support rods having end portions fixed to the support shafts, respectively, and extending in parallel to the left and right flanges while making contact with outer surfaces of the right and left flanges; an anti-rolling unit for the bobbin, wherein the anti-rolling unit includes a first anti-rolling unit having a plurality of first and second regions alternately formed on outer peripheral surfaces of the flanges having the plate shape, in which two adjacent first regions or two adjacent second regions make contact with a flat surface; and a second anti-rolling unit defined as the handle makes contact with the flat surface; an anti-rotation protrusion for the handle part protruding from an inner surface of the handle part; and a plurality of grooves provided on an outer surface of each flange to receive the anti-rotation protrusion of the handle part.
