Collapsible reel

Claim 2

A collapsible reel having an expanded and a collapsed position and comprising a pair of end flanges spaced one from another, a segmented cylindrical drum extending between the flanges having some segments between the flanges fixed in position on the flanges and other segments between the flanges movable relative to the flanges, and means connecting the movable segments to each other and to the fixed segments, wherein the fixed and movable segments are shaped so the movable segments can fold relative to the fixed segments when the reel is collapsed.

Claim 3

The reel of claim 1 wherein the drum is a right circular cylinder.

Claim 4

The reel of claim 1 wherein each of the segments has a portion of a side of its perimeter curved in an arc.

Claim 5

The reel of claim 3 wherein the radius of curvature of the arc is equal to the radius of curvature of the drum.

Claim 6

The reel of claim 3 wherein the connecting means permits the drum to collapse longitudinally.

Claim 7

The reel of claim 5 wherein the said arc portion lies adjacent to, and conforms with, the surface of an adjacent drum segment, when the drum collapses longitudinally.

Claim 8

The reel of claim 1 wherein some of the segments are hingedly connected by means of pivotally connected arms.

Claim 9

The reel of claim 7 wherein the arms have means for locking when the reel is in an expanded position.

Claim 10

A collapsible reel having an expanded and a collapsed portion and comprising a pair of end flanges spaced one from another, and a drum extending between and connected to the end flanges and having a cylindrical surface formed of segments with means supporting and connecting the segments whereby the reel can be expanded to receive cable thereon, and the reel can be collapsed when empty, some segments of the drum being fixed on the flanges, and other segments of the drum being pivoted relative to the fixed segments, and foldable relative to the fixed segments when the reel is collapsed, said fixed and foldable segments forming a surface for winding material thereon.

Claim 11

A collapsible reel having an expanded and a collapsed portion and comprising a pair of end flanges spaced one from another, and a drum extending between and connected to the end flanges and having a cylindrical surface formed of segments with means supporting and connecting the segments whereby the reel can be expanded to receive cable thereon, and the reel can be collapsed when empty, some segments of the drum being fixed on the flanges, and other segments of the drum being pivoted relative to the fixed segments, and foldable relative to the fixed segments when the reel is collapsed, said fixed and foldable segments forming a surface for winding material thereon.

Claim 12

A collapsible reel comprising a pair of flanges spaced apart, a drum formed of segments extending between and connected to the flanges having a cylindrical surface formed of some segments fixed to the flanges and other segments foldable relative to the fixed segments, and means connecting the movable segments to each other and to the fixed segments, wherein each segment is of a shape whereby in an expanded position, the drum surface of the reel forms a right circular cylinder, and in a collapsed position, the foldable segments are folded with respect to the fixed segments.

Claim 13

A collapsible reel comprising a pair of flanges spaced apart, a drum formed of segments extending between and connected to the flanges having a cylindrical surface formed of some segments fixed to the flanges and other segments foldable relative to the fixed segments, and means connecting the movable segments to each other and to the fixed segments, wherein each segment is of a shape whereby in an expanded position, the drum surface of the reel forms a right circular cylinder, and in a collapsed position, the foldable segments are folded with respect to the fixed segments.

Claim 14

The reel of claim 10 wherein the connecting means permits the drum to collapse longitudinally.

Claim 15

The reel of claim 10 wherein the foldable segments are spaced apart, whereby the drum, in an expanded position, has spaces in the surface.

Claim 16

In a collapsible reel for cable and the like, having a pair of flanges spaced one from another and a cylindrical drum extending between and connected to the flanges, folding segments forming a portion of the drum, segments fixed to the flanges forming the remainder of the drum, and means connecting the movable segments to each other and to the fixed segments, wherein the boundaries between fixed and folding segments include arcs which permit the segments to fold with respect to one another when the reel is collapsed.

Claim 17

In a collapsible reel for cable and the like, having a pair of flanges spaced one from another and a cylindrical drum extending between and connected to the flanges, folding segments forming a portion of the drum, segments fixed to the flanges forming the remainder of the drum, and means connecting the movable segments to each other and to the fixed segments, wherein the boundaries between fixed and folding segments include arcs which permit the segments to fold with respect to one another when the reel is collapsed.

Claim 18

A reel of claim 13 wherein the connecting means permits the drum to collapse longitudinally.

Claim 19

In the reel of claim 13, said folding segments being spaced apart to provide the drum with spaces.
