Abstract
Abstract The cord reel assembly comprises first and second identical hub-forming members. A plate is positioned between the inner ends of abutting cylindrical sections of the hub-forming members. First and second identical annular opposed shell members are held between outer symmetrical opposed disc sections of the respective hub-forming members. Each shell member has an outer inwardly positioned circumferential edge where each such shell member abuts the opposed shell member. A rivet-like member is provided for holding the cylindrical sections together with the plate situated between the inner ends of the cylindrical sections to form a hub assembly with each disc section bearing against one of the shell members to hold the shell members in place with the inner edges thereof in abutting relationship. Each shell member has a notch extending into the shell member from the outer circumferential edge thereof and adapted to register with an opposed identical notch in the opposed shell member. The plate has a radially extending slot therein adapted to be rotated into alignment with the notches when the notches are in registry with each other for receiving a loop of a cord. Manually manipulatable ribs are provided on the outer surface of each disc section of each hub-forming member for enabling the hub assembly to be rotated by hand relative to the shell members after a loop of cord has been inserted through the aligned notches and into the slot for winding up excess cord.
