Abstract
A caster wheel brake and anti-swivel system for carts and other wheeled articles is operable to secure free-castering wheels against swiveling rotation about their swivel axes, and against rolling rotation along their horizontal rotation axes. The system includes a swiveling caster wheel assembly and an actuation link, with an anti-swivel actuator and a brake actuator coupled thereto. Linear movement of the actuation link causes the anti-swivel actuator to engage the anti-swivel member that rotates with the caster wheel about the swivel axis, to selectively prevent the anti-swivel member and wheel from swiveling. The actuation link's movement also urges a brake actuator to move a wheel brake and drives a braking surface into engagement with the wheel, thereby preventing the wheel from rolling at the same time it is prevented from swiveling by the pawl. Optionally, a foot-operated torque shaft and a rack-and-pinion arrangement are used to operate the actuation link.

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.
