Patent number: 10781842Abstract: An expansion anchor is disclosed. The expansion anchor has a bolt having a neck region and an expansion region adjoining the neck region in which the bolt tapers down towards the neck region. The bolt has a groove in the neck region which extends along the bolt, and is at least partially surrounded by an expansion sleeve, and which has on its inside a web. The web at least partially engages in the groove in the neck region and the wall thickness of the expansion sleeve is increased locally by the web. The expansion sleeve is displaceable under radial expansion of the expansion sleeve along the bolt from the neck region into the expansion region. The web, on displacement of the expansion sleeve from the neck region, at least by region, passes into the expansion area and is forced radially outward by the expansion region.Type: GrantFiled: August 16, 2017Date of Patent: September 22, 2020Assignee: Hilti AktiengesellschaftInventor: Marc Schaeffer

Patent number: 10202999Abstract: A method for fixing an expansion anchor to a substrate includes introducing an anchoring zone and at least one part of a middle zone of a bolt of the expansion anchor into a hole in the substrate together with an expansion sleeve of the expansion anchor. The bolt is then moved relative to the expansion sleeve in a pull-out direction, as a result of which the expansion anchor is anchored to the wall of the hole. The space between the wall of the hole and the bolt is then filled to the height of at least one part of the middle zone with a curable mass such that the curable mass on the middle zone reaches up to an annular collar of the bolt, where the collar is configured as one piece with the bolt and is locally larger in cross-section, and the curable mass is cured.Type: GrantFiled: October 19, 2016Date of Patent: February 12, 2019Assignee: Hilti AktiengesellschaftInventors: Tanja Steinberg, Giuseppe Guida, Kathrin Sproewitz-Haefliger, Marc Schaeffer

Patent number: 9856897Abstract: An expansion anchor with a bolt as a first element and with an expansion sleeve, which at least partially surrounds the bolt, as a second element, is disclosed. The bolt has an expansion region for widening the expansion sleeve. One of the two elements has a groove running in the longitudinal direction of the expansion anchor and the other element has a projection, which engages at least sectionally in the groove. The groove has a narrowing, which inhibits an axial movement of the expansion sleeve relative to the bolt.Type: GrantFiled: September 2, 2014Date of Patent: January 2, 2018Assignee: Hilti AktiengesellschaftInventor: Marc Schaeffer

Patent number: 9810254Abstract: An expansion bolt including an anchor bolt having an expansion section, and further including an expansion sleeve which surrounds the anchor bolt and which can be expanded by retracting the expansion section, and a spring element arranged on the anchor bolt. The spring element can be tensioned by inserting the anchor bolt into a bore hole and can retract the expansion section of the anchor bolt into the expansion sleeve when it is released. An indicator element indicates when a rated tension of the spring element is reached.Type: GrantFiled: June 25, 2013Date of Patent: November 7, 2017Assignee: Hilti AktiengesellschaftInventors: Andreas Eckstein, Mathias Goldt, Marc Schaeffer, Arjen Detmer Dijkhuis, Joerg Appl
