Patent number: 9360039Abstract: The invention relates to a cage nut (1) having a retaining device, and to a method for producing the same. The cage nut (1) comprises a nut (4) having a radially protruding rectangular flange (5) and a threaded sleeve-like seat (6) for a screw. A retaining means (7) having a through-opening (8), through which the sleeve-like screw seat (6) passes, engages in a bracket-like manner over the rectangular flange (5) of the nut. A retaining collar (9), which surrounds the sleeve-like screw seat (6) of the nut (4), is supported on the retaining means (7) in the region of the through-opening (8). The retaining collar (9) is one-piece and has first and second cover elements (10, 11) covering the through-opening (8) of the retaining means (7) on both sides. The cover elements (10, 11) are mechanically connected via a connecting bush (12) concentrically adjoining the screw seat (6). The connecting bush (12) is radially spaced from the through-opening (8).Type: GrantFiled: December 16, 2011Date of Patent: June 7, 2016Assignees: Ruia Global Fasteners AG, GM Global Technology Operations LLC.Inventors: Thomas Endt, Rainer Krauss, Siegfried Oberndörfer, Stefan Neuhäuser
