Abstract
A ratchet adjustment system has an elongated adjustment strip with teeth extending along the strip. The teeth form a ratchet mechanism when ends of the strip are inserted into a locking mechanism having a base plate and locking devices. The strip ends are inserted into the locking devices from opposite directions, so that the system forms a closed circle. The circumference of the system is reduced by pressing opposite sides of the strip together so that the insertion ends are inserted further through the locking devices, and the circumference is increased by pulling the strip away from the locking devices. Depending on the geometry of the teeth and locking devices, the amount of force needed to reduce and increase the circumference could be equal, or the amount of force required to reduce the circumference could be less than the amount required to increase the circumference.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
