Abstract

A collapsible reel that can be broken down into smaller components for ease of shipping or to change out the drum is provided. The reel comprises a drum assembly, a pair of flanges and a pair of coupling assemblies for removably affixing each flange to the drum assembly.

First claim

The invention claimed is:

1. A reel comprising:
a drum assembly comprising a drum having an inner diameter and configured to receive wound product, the drum having opposing ends, the drum assembly also comprising a drum plate affixed to each end and having a central opening therein;
a first flange comprising a flange center ring having a diameter slightly smaller than the inner diameter of the drum so that the flange center ring can slide within the drum, spokes extending radially outward from the flange center ring and having distal ends, and a rim affixed to the distal ends of the spokes;
a second flange comprising a flange center ring having a diameter slightly smaller than the inner diameter of the drum so that the flange center ring can slide within the drum, spokes extending radially outward from the flange center ring and having distal ends, and a rim affixed to the distal ends of the spokes; and
two coupling assemblies, one for removably affixing each flange to the drum assembly, wherein each coupling assembly comprises at least one block affixed to the drum plate and sized to fit between adjacent spokes, a locking plate that fits over the flange center ring, and fasteners that affix the locking plate to each of the at least one block.

2. The reel of claim 1 wherein:
the number of blocks is at least two and the blocks are substantially equally circumferentially spaced apart on the drum plate.

3. The reel of claim 2 wherein:
the number of blocks is three.

4. The reel of claim 3 wherein:
the blocks are welded to the drum plate.

5. The reel of claim 2 wherein:
each block defines a threaded bore;
each locking plate defines fastener openings in substantial axial alignment with the threaded bores and configured to receive the fasteners.

6. The reel of claim 5 wherein:
the fasteners are bolts.

7. The reel of claim 5 wherein:
each block is wedged between a pair of adjacent spokes to help prevent rotational movement of the flanges with respect to the drum assembly.

8. The reel of claim 5 wherein:
each block is wedge shaped.

9. The reel of claim 5 wherein:
each block has non-parallel angular sides that abut the spokes.

10. A method of assembling a reel comprising the following steps:
Providing a drum assembly comprising a substantially cylindrical drum having an inner diameter and opposing ends and a drum plate affixed to each opposing end and having a central opening therein;
Providing two flanges each flange comprising a substantially cylindrical flange center ring having an outer diameter slightly smaller than the inner diameter of the central opening, spokes extending radially outward from the flange center ring and having distal ends, and a rim affixed to the distal ends of the spokes;
Providing two coupling assemblies, each coupling assembly comprising a plurality of circumferentially spaced apart blocks affixed to one of the respective drum plates, a locking plate and fasteners;
Sliding each flange center ring within the drum so that each block fits between adjacent spokes;
Sliding each locking plate over one of the respective flange center rings until the locking plate abuts the spokes; and
Attaching each locking plate to the plurality of blocks using the fasteners.
