ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The invention herein relates to a telecommunications cord reel structural design, specifically referring to a telecommunications cord reel for neatly rewinding the telecommunications cord of conventional telephones and handsets, preventing the entanglement of such telecommunications cords and, furthermore, that is capable of achieving easy cord extension at minimal force, while also automatically rewinding the cord when the handset is cradled on the telephone.
2) Description of the Prior Art
Most conventional telecommunications cords utilized between telephones and handsets are designed with preformed helical coils capable of stretching and returning to original length, such that when users utilize the telephone, the elastic properties of the telecommunications cord increases the extension range of the handset, but without the occurrence of binding. However, the said helical-type handset telecommunications cord following a given frequency of usage tends to become twisted by the manual force of the user, causing the coils to become entangled and resulting in a feeling of increased grasping tension when the handset is picked up and, furthermore, excessively twisting the telecommunications cord at the handset, the strain of which could easily break the individual conductors inside.
SUMMARY OF THE INVENTION
The primary objective of the invention herein is to provide a telecommunications cord reel design comprised of a housing internally containing a reel, a rewinding mechanism, and other components and in which the reel consists of an upper reel plate and a lower reel plate that are engaged together for assembly and, furthermore, the telecommunications cord is routed through insertion notches in the center of the reel, enabling the telecommunications cord to be wound around the upper and lower end faces of the reel, with the rewinding mechanism anchored on an annular wall at the top end of the lower reel plate. As such, the structure of the present invention provides for the automatic rewinding and storage of the telecommunications cord on the reel and, furthermore, cord extension requires minimal force and overall operation is simpler and more convenient.
Another objective of the invention herein is to provide a telecommunications cord reel design in which the rewinding mechanism utilizes two elastic components that are anchored to the two ends of the annular walls of the reel, with the other extremities actively hinged around a fixed area such that pulling out the exposed end of the telecommunications cord causes the reel to rotate producing in the process a fixed retractile tension of a torsion spring anchored around the annular wall of the reel; as such, the telecommunications cord can be extended for utilization easily with minimal force or automatically rewound.
