Abstract
Abstract For fastening a cover part at a frame part in which both parts have at least a metallic frame structure, spherical segments formed out of the frame part with fasteners in the form of balls are provided while the counter fasteners are constructed as collars which are components of the cover part and extend angularly bent in the direction of the frame part. After inverting the collars over the balls, each collar is pressed flat by a predetermined amount under straightening during a pressing operation in which the frame part serves as supporting surface so that at the end of the deformation operation, the collar is supported at the ball.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
116 words
a method for fastening a cover part at a frame part with the aid of fastening means each having a ball head secured at one part and engaging from below at coordinated counter fastener means at the other part, comprising the steps of providing spherical segments formed out of the frame part with fastener means constructed as balls, mounting over the balls counter fastener means in the form of ring-shaped collar means angularly bent in the direction of the frame part and formed out of the cover part, and thereafter pressing flat each collar means by a predetermined amount under straightening thereof during a subsequent pressing operation in which the frame part serves as support surface.
