Patent ID: 10033121

Abstract:
A system (100) includes a threaded boss (101) defining a central axis (104), a metal panel (102), and a fastener (103) to couple the metal panel to the threaded boss. The fastener includes a threaded shaft (105) terminating at a paddle (106), which can be oblong. The metal panel can define an oblong aperture (112), where the paddle is to pass through the oblong aperture when rotated (115) to a first rotational alignment (113) about the central axis. The metal panel can also include one or more retention contours (116,117) disposed adjacent to the oblong aperture. Each retention contour can include a ramp (118,120) defined by a curved central axis (305) and a retention bridge (119,121) defining a recess (122,123) to receive the oblong paddle when rotated to a second rotational alignment (114) about the central axis.
