<p>A blind rivet assembly is disclosed. The rivet assembly comprises a mandrel (12), a rivet body (14), a buckle sleeve (16), an expanding wrinkle sleeve (17), a pressure sleeve (15) and a locking collar (18). The sleeves, rivet body and collar are slideably disposed about the mandrel with said buckle sleeve (16) disposed adjacent one end of the body (14), and the mandrel (12) extending through the body (14) and beyond the other end thereof. The buckle sleeve (16) has a generally cylindrical configuration such that when subjected to a pulling force, the sleeve buckles outwardly from the mandrel, slides about the rivet body and engages a workpiece. The wrinkle sleeve (17) has a generally cylindrical, but longitudinally corrugated configuration, such that as the mandrel (12) proceeds through the rivet body (14), the wrinkle sleeve (17) expands radially and helps create and interference fit between the rivet body (14) and an opening in the workpiece.</p> |
