Abstract

A collapsible reel comprising a pair of similar flanges connected by a tubular hub composed of at least a pair of similar segments, similar bosses being affixed to a planar surface of each of the flanges, said bosses having arcuate grooves in the peripheral surfaces thereof and the opposite ends of the concave surfaces of the hub segments having arcuate ribs thereon complementary in shape and size to the grooves in said bosses for reception into said grooves, thereby interlocking the flanges to the hub. Bolt means extending through portions of the hub segments and into other portions engage nuts in said other portions to secure the hub segments in operative relationship with each other and interlock to said flanges. The abutting edges of the hub segments also have interfitting lugs and recesses to align the same with each other and insure a cylindrical outer surface on said hub to receive material to be wound thereupon between said flanges.

Dependent claims

A collapsible reel comprising in combination, a pair of similar unitary flanges each having at least one planar face;

a substantially tubular hub the opposite ends of which abut said planar faces of said flanges, said hub being composed of a plurality of similar arcuate segments having concave inner surfaces;
and means detachably connecting said ends of said hub in abutting relationship respectively to said planar faces of said flanges comprising similar bosses fixed centrally to and extending axially from said planar faces of said flanges and having arcuate grooves in the peripheries of said bosses positioned therein axially outward from said planar faces of said flanges, said segments of said hub having on said concave surfaces thereof arcuate ribs complementary in shape and size to said arcuate grooves in said bosses and respectively received closely therein when said hub segments are positioned operatively between said flanges with the ends thereof abutting said planar faces of said flanges, and means connecting said segments to each other to maintain said hub connected operatively to said flanges.
