Patent ID: 8720657

Claim:
A rewindable electrical cable extension device for coupling between first and second connectors, the device comprising: a housing having first and second cable exit ports; a cable having a first end and a second end defining opposing extremities of first and second contiguous sections of the cable; the first end of the cable protruding through the first exit port and being configured for connection to the first connector; the second end of the cable being fixedly mounted in association with the second exit port and being configured for connection to the second connector; the first section of the cable being wound in a first direction on a rotating spool that is configured to rotate within the housing; a common junction of the first and second sections of the cable being anchored to the rotating spool; and the second section of the cable being wound in an opposite direction to the first section so that unwinding the cable by pulling on the first end extracts the first section of the cable from the housing and uncoils the second section within the housing without rotating the second end of the cable wherein: the second section of the cable is coiled on a non-rotating spool; and the cable passes through a peripheral slot in the non-rotating spool which separates the first section of the cable from the second end thereof.
