Abstract
Transportation equipment having at least one deck for supporting and transporting four-wheel vehicles such as automobiles and trucks; at least one track secured to the deck; the track having a pair of substantially upwardly extending spaced apart surfaces; chock blocks for a vehicle transported on the deck to secure the vehicle against longitudinal movement; each chock block having a horizontal first member which nests with the track and is quickly removable from such nesting arrangement by upward displacement; each chock block having a second member substantially horizontally positioned and permanently laterally joined to the first member; the second member having a sufficient length to extend along, and terminate beyond, the tread face of a tire of a vehicle located along side the track; and the chock block having a lock for removably securing the first member to the track, when in nesting position therewith, to prevent the chock block from horizontal movement along the track and upward movement from the track.

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.
