Abstract:
1. A blind rivet for a threaded joint between a support member and a mounting member, said blind rivet comprising: a body comprising a sleeve-shaped shank of elastic material adapted to be inserted into a mounting hole of said support member, said shank comprising a mounting flange, a folding zone adapted to be folded into a fold by a folding operation between a non-folded configuration and a folded configuration, and a first anchoring portion, said mounting flange and said folding zone being adapted to be supported against opposite sides of said support member in said folded configuration, said folding zone and said first anchoring portion being joined by a wall of reduced cross-section to define a desired buckling area for enabling said folding operation, said body being an injection molded part made by injection molding of material about said sleeve, a sleeve of metallic material disposed within said body, said sleeve comprising a support portion in said folding zone, said support portion being longitudinally displaceable with respect to said body for performing said folding operation, said sleeve having a second anchoring portion adjacent to said support portion and provided with an annular recess, said first anchoring portion comprising an anchoring projection which, in said non-folded configuration, extends radially inwards and completely fills said annular recess of said second anchoring portion so as to provide for a positively interlocking connection between said sleeve and said body, and means for preventing twisting and torsional deformation of said body.
