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

Publication number: 20230241818Abstract: A method of manufacturing and assembling a first and a second object wherein the first object is made by bringing a flowable compound into a first object shape and then subjecting the flowable compound to a hardening process that results in a change of a chemical composition of the flowable compound, thereby creating the first object or a part thereof. Then, the first object is positioned relative to a second object, and a flow portion of the hardened article of the modified compound is caused to become flowable by an input of energy. An interpenetration zone of the flow portion and structures of the second object is created, and the flow portion is allowed to re-solidify, whereby the interpenetration zone between the re-solidified flow portion and the structures of the second object secures the first and second objects to each other.Type: ApplicationFiled: June 30, 2021Publication date: August 3, 2023Inventors: Mario Lehmann, Jörg Mayer, Anna Forshufvud

Publication number: 20230234300Abstract: A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.Type: ApplicationFiled: March 30, 2023Publication date: July 27, 2023Inventors: Jörg Mayer, Mario Lehmann, Laurent Torriani
