Abstract: A collapsable reel using a sectional rim comprising articulated saddle shaped sections. One side of a section is fixed. A central bottom part can be tilted and the other side is fully inclinable. The lowering of the bottom added to the lowering of one side allows effortless removal of the coil. The reel comprises a central shaft, a set of eight radial arms fixed to the shaft and a second set of radial arms pivotally mounted on a slider bushing which is slidably related to the base of the fixed radial arms by a two arm linkage. A radially directed pin hinged at the intersection of the linkage is actuated by a sliding wedge located within the shaft and pulled by a handle, which pushes the pin outwards thereby folding the linkage. When the linkage is thus folded, it pulls in a slider linked to the articulated rim sections, thereby collapsing the sections to a smaller inside diameter than is possible when simply tilting a one piece saddle section.
