RETRACTABLE CORD REEL
First Claim
Patent Images
1. A retractable cord reel assembly comprising:
- an inner housing including a front retention plate, a cord retention ring, a middle retention plate and a rotational biasing assembly; and
a single continuous cord having a round exterior profile, said cord including a display fixture cord distal end configured to engage a power/signal source, a coiled portion disposed adjacent the display fixture distal end and external to the front retention plate, a middle portion disposed adjacent the coiled portion that extends through an aperture in the front retention plate into an inner volume defined by an internal surface of the cord retention ring and the front and middle retention plates and through an exit channel defined in the cord retention ring into an outer volume defined by an external surface of the cord retention ring and the front and middle retention plates, said middle portion configured to be wound on and unwound from the cord retention ring, and a device cord distal end configured to engage an electronic device disposed adjacent to the middle portion;
wherein the coiled portion dynamically absorbs radial energy generated along the cord when the cord is wound on and unwound from the cord retention ring.

Abstract
A retractable electrical conductor cord reel assembly comprising a single continuous round cord from a display fixture cord end to a device cord end, wherein the cord includes a coiled portion disposed between a cord retention ring and the display fixture cord end to accommodate and/or compensate for torsional forces in the cord associated with the pay out and gathering of the cord.

6. A method comprising:
-
moving a device end of a single continuous cord having a round exterior profile between a first operative orientation defined when a middle portion of the cord is substantially wound around a cord retaining ring in an outer volume defined between an exterior surface of the cord retaining ring and a front retention plate and a middle retention plate, and a second operative orientation defined when the middle portion of the cord is substantially unwound from the cord retaining ring; and absorbing radial energy dynamically in the coiled portion in response to the moving step by decreasing the diameter of a coiled portion of the cord that is disposed between a display fixture end disposed at a distal end of the cord and the front retention plate when the device end is moved from the first operative orientation to the second operative orientation and by increasing the diameter of the coiled portion when the device end is moved from the second operative orientation to the first operative orientation. - View Dependent Claims (7, 8)
