Patent ID: 7465135

Claim:
A u-nut assembly, comprising: a) a substrate including a polymer; b) a first substrate segment, a second substrate segment, and a flex area, wherein the first substrate segment and the second substrate segment are located adjacent to the flex area and the flex area is configured so that the first and second substrate segments are capable of being brought into contact by moving along a predetermined path; c) a retainer including a first securing member and a second securing member, wherein the first securing member includes a first angled surface and a first coupling surface and the second securing member includes a second angled surface and a second coupling surface, wherein the retainer is located on the first substrate segment; d) an acceptor located on the second substrate segment including a first cooperating surface, a second cooperating surface, a first securing surface, and a second securing surface, wherein the first and second securing members are snap fit within the acceptor, whereby: i. the flex area flexing so that the first and second substrate segments are brought into closer proximity; ii. the flex area flexing so that the first angled surface contacts the first cooperating surface and the second angled surface contacts the second cooperating surface to force the first and second securing members a distance together; iii. the flex area flexing so that the first and second angled surfaces move beyond the cooperating surfaces; iv. the flex area flexing so that after the first and second securing members are forced a distance together they move a distance apart; v. the flex area flexing so that the first coupling surface engages the first securing surface and the second coupling surface engages the second securing surface thereby coupling the acceptor to the retainer; and e) a fastener configured to tap threads into the acceptor, wherein the fastener exerts a clamping force on at least one of the substrate segments.
