A headphone reel is disclosed comprising a base having a midpoint about an axis and opposed "L-shaped" flanges extending upwardly and then inwardly toward the midpoint. A spindle, is mounted about the axis between the base and the underside of the inwardly facing flanges. The spindle comprises a central disc segment having an outer circumference. A dial section extends from the top of the disc and has an upper section further extending between and above the flanges, the upper section having slots to receive a loop of the cable. A circumferential shoulder extends outwardly on the dial beneath the flanges. A hollow cylindrical ratchet gear is attached to the underside of the disc, with teeth on the outer surface and a spring catch on the inner surface. The ratchet rests within a semi-circular wall in the base disposed about the axis. A coilable spring connects between the base midpoint and the spring catch to provide rotational force to the spindle. Movement of the spindle, when the spring is pre-tensioned, is controlled by a pawl lever. When the pawl is released, the spring force rotates the spindle to coil the cable into the device. |
