Abstract
A blind rivet comprising a shank and a rivet body enclosing the shank, the rivet body containing in the cylindrical wall thereof wedge means and windows possessing spaces for admitting the wedge means such that, when the blind rivet is inserted through holes perforated in advance in the panels to be joined therewith and, subsequently, the shank is slid up the interior of the rivet body, the cylindrical wall of the rivet body is bent outwardly in the radial direction and, at the same time, the wedge means are raised and forced into the spaces of the windows, causing the cylindrical wall of the rivet body to be brought into tight contact with the edges of the holes in the panels and consequently enabling the blind rivet to be secured to the panels.
