Abstract
An improved temporary guard rail system for use by residential and commercial builders on construction sites in those areas of building structures where an accidental fall may result in serious bodily injury. In particular, the temporary guard rail system of the present invention includes a plurality of upright stanchions having mounting brackets integrally formed or attached thereto that are connected by a plurality of vertically spaced, generally horizontal side rails extending end to end. The vertically spaced side rails are adapted for 360 degree rotational movement in both horizontal and vertical planes. In addition, the tubular guard rails are fabricated in a plurality of sections that may be slideably engaged, one inside another, to provide a telescoping adjustment of length. The temporary guard rail system may be adapted and secured to various features of a building such as balconies, elevated platforms, stair cases, and the perimeter of a floor prior to the external walls or permanent protective railings being erected to prevent accidental injury. Further, the temporary guard rail system is designed and manufactured to conform to OSHA requirements for temporary guard rails. This system also provides a versatile safety device which is easy to install, ready to dismantle, and relatively inexpensive to manufacture.

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.
