发明名称 RETRACTABLE CORD REEL ASSEMBLY
摘要 A reel body rotatably supported on a frame and spring-urged into a given reference position includes a main peripheral cord storage compartment having an axial and radial extent each equal to a number of cord thicknesses, a cord take-up compartment positioned alongside said main cord storage compartment and having an axial extent of only about one cord thickness. The main cord storage and cord take-up compartments respectively having hub portions around which different portions of the same cord are wound initially in the same direction, the ub portion of the main cord storage compartment being positioned substantially outwardly of the hub portion of the cord take-up compartment. The cord wound around the hub portion of the main cord storage compartment has an inner winding connected to the first or inner winding on the hub portion of the cord take-up compartment which joins a number of windings which is only a fraction of the number of windings in the main cord storage compartment.
