Abstract: A mounting assembly for attaching an umbrella cover or cloth to the ribs of an umbrella without sewing includes a flattened section integrally formed in the rib near the tip having opposed upper and lower surfaces each formed with a seat, and a throughbore extending between the seats which receives a rivet. A peripheral portion of the umbrella cloth is first inserted through the bore in the flattened section, and then the rivet is inserted into the bore so that the umbrella cloth is clamped between the head of the rivet and the seat in the upper surface. The lower, deformable end portion of the stem of the rivet is thereafter flattened against the seat in the lower surface of the flattened section, with the umbrella cloth interposed therebetween, to securely attach the umbrella cloth to the rib.
