Patent number: 11911972Abstract: A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.Type: GrantFiled: April 13, 2022Date of Patent: February 27, 2024Assignee: WOODWELDING AGInventors: Jörg Mayer, Joakim Kvist, Philipp Bernhard, Laurent Torriani, Mario Weiss, Antonino Lanci, Martin Sigrist, Hannes Merz, Samuel Malzach

Patent number: 11904551Abstract: A method of anchoring a lightweight building element having a first building layer and an interlining layer distally of the first building layer, and possibly a second building layer distally of the interlining layer. For anchoring, the distal end of a connector element is inserted into a mounting hole in the lightweight building element, and also a sleeve including a thermoplastic material is inserted into the mounting hole, the sleeve enclosing the connector element. Then, a distally facing liquefaction face of the sleeve is caused to be in contact with a proximally facing support face of the connector element. Energy impinges to liquefy at least a flow portion of the thermoplastic material of the sleeve, and the liquefaction face is pressed against the support face to cause at least a fraction of the flow portion to flow radially outward. After the flow portion has re-solidified, it anchors the connector element in the receiving object.Type: GrantFiled: July 12, 2019Date of Patent: February 20, 2024Assignee: WOODWELDING AGInventors: Mario Lehmann, Laurent Torriani, Muthumariappan Sankaran, Joakim Kvist
