Abstract
Abstract A pair of disc-shaped flanges having centrally located arbor holes defining an axis for the reel are axially spaced by a plurality of collapsible strut assemblies affixed to the flanges at opposite ends and split at their mid-portion, joined at such split by a lost motion pivotal connection. Hinges are provided the strut assemblies proximate the flanges to provide an articulated assembly which folds radially outward. Clamping means adjacent the hinges hold the assembly rigid in an empty but extended position of the reel. Bolts are provided between the flanges to lock the reel in a collapsed condition. A transportation fixture comprises an upright spindle on a platform over which the collapsed reels are stacked, arbor holes of the reels receiving the spindle. Securing means clamps the stack of collapsed reels to the platform.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
246 words
A collapsible reel for wire and cable packaging comprising: a pair of disc-shaped flanges spaced along an axis of said reel; a plurality of collapsible strut assemblies connected at opposite ends thereof to respective said flanges, said strut assemblies being arranged parallel to said reel axis at equal radial distances from said reel axis, forming a drum between said flanges; each said strut assembly comprising a pair of equal length sections joined at a pivotal connection intermediate said flanges, said pivotal connection comprising a pin on one of said sections received in slots elongated parallel to said reel axis in the other of said sections, each said strut assembly section further comprising a hinged connection proximate a respective said flange, said hinged connection comprising a hinge support assembly affixed to said respective said flange in co-extensive alignment with a respective adjacent said section, a pin on one of said hinge support assembly or said section received in holes in the other of said hinge support assembly or said section establishing a hinge axis, said sections being pivotable about said hinged connections carrying said pivotal connection radially outward of said reel axis to collapse said reel; and clamping means at each hinged connection on at least one of said strut assemblies, said clamping means being located radially inward of said hinge axis relative to said reel axis, clamping said section and said hinge support assembly together in abutting engagement in an extended position of said strut assembly.
Claim 2
Dependent Claim
246 words
A collapsible reel for wire and cable packaging comprising: a pair of disc-shaped flanges spaced along an axis of said reel; a plurality of collapsible strut assemblies connected at opposite ends thereof to respective said flanges, said strut assemblies being arranged parallel to said reel axis at equal radial distances from said reel axis, forming a drum between said flanges; each said strut assembly comprising a pair of equal length sections joined at a pivotal connection intermediate said flanges, said pivotal connection comprising a pin on one of said sections received in slots elongated parallel to said reel axis in the other of said sections, each said strut assembly section further comprising a hinged connection proximate a respective said flange, said hinged connection comprising a hinge support assembly affixed to said respective said flange in co-extensive alignment with a respective adjacent said section, a pin on one of said hinge support assembly or said section received in holes in the other of said hinge support assembly or said section establishing a hinge axis, said sections being pivotable about said hinged connections carrying said pivotal connection radially outward of said reel axis to collapse said reel; and clamping means at each hinged connection on at least one of said strut assemblies, said clamping means being located radially inward of said hinge axis relative to said reel axis, clamping said section and said hinge support assembly together in abutting engagement in an extended position of said strut assembly.
Claim 3
Dependent Claim
43 words
The collapsible reel of claim 1 wherein said clamping means comprises a bolt rotatably carried by said hinge support assembly threadably engagable with cooperatively threaded means on said adjacent section axially aligned with said bolt in said extended position of said strut assembly.
Claim 4
Dependent Claim
17 words
The collapsible reel of claim 2 wherein said bolt is disposed axially parallel to said reel axis.
Claim 5
Dependent Claim
19 words

Claim 6
Dependent Claim
46 words
The collapsible reel of claim 1 wherein said holes are disposed in members affixed to sides of one of said hinge support assembly or said adjacent section, said members locating said holes laterally offset from a plane containing said hinge support assembly and said adjacent section.
Claim 7
Dependent Claim
36 words
The collapsible reel of claim 1 wherein said elongated slots are disposed in members affixed to sides of said other of said sections, said members locating said slots laterally offset from a plane containing said sections.
Claim 8
Dependent Claim
42 words
The collapsible reel of claim 1 wherein said sections each comprise an arcuate plate at a radially outboard edge of said section relative to said reel axis, said arcuate plate being curved concentrically about said reel axis, forming a drum surface segment.
Claim 9
Dependent Claim
39 words
The collapsible reel of claim 7 wherein said strut assemblies are arranged at equal angular positions relative to said reel axis and edges of adjacent said arcuate plates parallel to said reel axis are contiguous in said extended position.
Claim 10
Dependent Claim
34 words
