Title: Process and fastening for connecting vibrating objects
Inventor: KROEGER DIETRICH
IPC: F16B31/04
Filed: 1988-12-16
Abstract: A description is given of a process for connecting two objects (1, 2), a fastening (3) essentially comprising an anchorage part (4), a spring element (6) and an intermediate piece (7), and the fastening being anchored in the second object (2) and having a contact-pressure surface (8) facing said second object.
