Patent attributes
New fastening devices and techniques are provided. A new self-ratcheting cord is provided, with unlimited possible divisions and insertion points for self-threading and -ratcheting along its length. In some embodiments, the insertion points have ports through which an end of the cord can be threaded. Ridges perpendicular to the length of the cord line the exterior and have an appropriate size, shape and material permitting the cord to move in the direction of insertion through the ports, but limiting reversal. In some embodiments, ridges also line the inside of each port, parallel to the port, and perpendicular to a length of cord at points threaded through the port. In some embodiments, the ports themselves have an exterior shape to lock the cord. Some embodiments also have periodic scoring and other built-in devices to permit snapping the cord by hand at any desired length.
