SPRING NUT

A spring nut for attaching a threaded object (60) to a structure with reentrant lips (52). The spring nut can include a base (122), a first arm and a second arm (114a, 114b) extending from the base in a first direction, and legs extending laterally from the base. The arms can include a support porti...

Zusammenfassung:	A spring nut for attaching a threaded object (60) to a structure with reentrant lips (52). The spring nut can include a base (122), a first arm and a second arm (114a, 114b) extending from the base in a first direction, and legs extending laterally from the base. The arms can include a support portion (118), a structure-engagement portion (116), and a thread-engagement portion (130) that can be configured to secure the threaded object against axial loading in a second direction opposite the first direction. Crumple zones (144a, 144b) in the support portions can deform upon loading of the threaded object in the second direction to cause the structure-engagement portion to be urged into the reentrant lips. Each of the legs can extend at a first angle from the base, toward the structure-engagement portions, to be disposed to contact an exterior surface of the reentrant lips.
