Benefits of technology

[0011]2. A feature in the former tube that prevents premature release of the first several knots onto the linear structure during application.
[0012]3. Stiffening of one end of the former tube to facilitate crushing the tube into a frustum of a cone to improve dispensing of the knots and handling during installation.
[0013]4. A loop of the elastic cord formed at one end of the assembly of the elastic with a linear structure to bind a connecting linear structure and eliminate disconnecting of the cords during use.

Problems solved by technology

So much so, that he believes that it would be difficult or impossible for a competitor to create a successful product based on the original patent without these improvements.

Embodiment Construction

[0022]The preferred embodiment of the referenced patent is a length of elastic cord 1 that has been formed into a plurality of slippable knots 2 around the exterior diameter of a former tube 4, having an internal diameter that is larger than the largest outside dimension of the largest feature a flexible linear structure 11, such as a connector on an electrical cord. This invention teaches a deformable former tube 4 comprised of a cylinder with one end stiffened 5 by rolling the material of the tube 4 into a bead 5 and an opposing non-stiffened 6 end. Each slippable knot 2, having at least one loop 3 around the former tube 4 such that the elastic, is a series of slippable loops 3 secured by knots 2 around the former tube 4. The knots 2 are arranged in an offset pattern 12, down the major axis of the former tube 4, such that the loops 3 can be in the closest possible proximity to the next loop. The loops 3 may be loosely positioned or tightly stretched around the structure depending ...

Abstract

Improvements to a device as previously disclosed in U.S. Pat. No. 7,219,397 wherein an elastic cord is attached to a pre-existing flexible linear structure such as a wire, tube, or rope to deform the structure and impart elastic handling properties. The improvements include features necessary for the effective manufacture and use of the device.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001]U.S. Pat. No. 7,219,397 B2FEDERALLY SPONSERED RESEARCH [0002]Not applicableSEQUENCE LISTING OR PROGRAM [0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]1. Field of Invention[0005]The Curly Cord retractile arrangement is common on all types of linear structures including leashes and tubing, but most commonly the telephone hand-set. It has the function of making the cord more convenient and functional. The inventor was awarded the abovementioned US patent for a retrofit device that imparts retractile properties to formerly non-retractile cords. This submission teaches novel and important features that are required to perfect the invention for the marketplace and for manufacturing.[0006]2. Prior Art[0007]The current application builds on the invention of U.S. Pat. No. 7,219,397 B2 Dated May 22, 2007 issued to the inventor, Todd N Bishop.[0008]Since issuance, the inventor has diligently pursued reduction to practice, including experiment...
