Abstract
A vertically adjustable emergency support for the bodies of, for example, rail vehicles. Due to wear of the wheel tires, the bogie frame and the car body supported on it tend to descend. In the case of emergency supports in the region of the center pivot, where access is difficult, it is proposed, in order to compensate for this drop, to connect the striker plate which faces an emergency spring at a distance 'w' to a box underneath which as vertically guided via guide elements on sliding-contact liners of a cut-out in the bogie frame. If the distance 'w' increases due to wear of the wheel tires, an adjustment has to be made by raising the box via a plate connected to the center pivot. Plates of a thickness which compensates for the wear are inserted between the box and abutments which are connected to the bogie frame. After securing the plates via bolts, the car body is lowered again, whereupon the distance 'w' is restored. In another embodiment for fixing the box relative to the bogie frame, after the box has been moved upwards far enough to restore the clearance 'w' , it is fixed in its position by a saw tooth connection including saw teeth engaging in a positive connection produced between the box and the bogie frame.

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.
