Abstract
A nut retainer for use with a structural member having a nut entrance channel defined between a pair of opposed shoulders or flanges of some predetermined thickness and a nut receiving channel disposed beneath the shoulders. The nut retainer has a generally frusto-conical body constructed from a resiliently deformable polymeric material with the body smaller diameter end fixedly secured to a rectangular nut upper face in a surrounding relationship with a threaded fastener receiving opening. The body larger diameter end is spaced from the nut upper face by some predetermined distance and has a diameter greater than the width of the structural member entrance channel. The retainer body is conformed such that the body exterior side wall will engage the structural member shoulders at areas therealong which are spaced from the nut upper face by a distance which is less than the thickness of the shoulders when the nut is inserted width-wise into the entrance channel. A force applied against the nut retainer causes it to be slightly deformed and allows simultaneous rotation of the nut and retainer 90 degrees so that the nut is captured in the receiving channel beneath the shoulders. When the force on the retainer is released, the retainer moves back toward its unstressed condition and causes the nut upper face to be drawn into an engaging relationship with the underside of the shoulders.

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.
