Patent number: 11608850Abstract: A connector for butt-connecting two chipboard components having two connector parts, which, mutually rotated through 90°, can be pushed together, into one another, into a locked assembly position and are in the form of U-shaped brackets having two outer bracket arms, which respectively have a rear plug-in portion for insertion into a circular drill hole of one component and an expandable front plug-in portion, forming the free bracket end, for insertion into a circular drill hole of the other component. A middle bracket arm is for expansion of the two front plug-in portions of the respectively other bracket in the assembly position. At least one locking portion for the mutual locking of the two brackets in the assembly position is provided. The outer sides of the rear plug-in portions are each configured, at least approximately, as partial lateral surfaces of the same circular cylinder.Type: GrantFiled: March 27, 2020Date of Patent: March 21, 2023Assignee: Häfele GmbH & Co KGInventors: Michael von Wilcke, Peer Leistert, Gerd Sawatzki, Gunter Nitschmann

Patent number: 11401961Abstract: A double connector for butt-connecting two components includes a guide bolt having a respective bolt section tapering in the direction of each bolt end on both sides of a middle bolt section. Two spreading sockets are movably guided on the guide bolt and which in each case can be pushed together from an outer socket end position toward the middle bolt section into a mounted position. The two spreading sockets are latched against being pushed back, wherein the spreading sockets each have at least one spreading tab which is expanded outwardly via the guide bolt in the mounted position.Type: GrantFiled: September 22, 2018Date of Patent: August 2, 2022Assignee: Häfele GmbH & Co KGInventor: Gunter Nitschmann

Patent number: 11204053Abstract: A rear wall/panel connector includes a stud, which has a receiving groove and two walls projecting vertically from the stud on both sides of the receiving groove. The two walls each have an opening configured for screwing in a screw. One of the two walls forms an arm of a rocker which is mounted on the stud wherein it is pivotable between a starting position and an end position about an axis which is parallel or almost parallel to the longitudinal direction of the receiving groove. The inside of the second wall is positioned obliquely outwards with respect to the longitudinal center plane of the receiving groove in the starting position and extends parallel to the longitudinal center plane in the end position. The other rocker arm projects outwards over the stud, at least in the end position.Type: GrantFiled: April 6, 2018Date of Patent: December 21, 2021Assignee: HÄFELE BERLIN GMBH & CO KGInventors: Rüdiger Walz, Gunter Nitschmann

Patent number: 11085476Abstract: A fitting for releasably connecting two furniture parts includes a first fitting part fastened on a first furniture part and a second fitting part fastened on a second furniture part. The second fitting part has at least one rigid latching cam which is engaged behind by a latching nose being provided on a deflectable latching tongue of the first fitting part. The latching tongue can be moved from its locking position engaged behind the latching cam, into a release position which can be fixed to the second fitting part. The latching tongue has at least one latching spring which can be deflected transversely to the deflecting plane of the latching tongue by a counter bearing of the second fitting part. The free spring end of the latching spring remains deflected by the counter bearing from the locking position until before the release position of the latching tongue is reached.Type: GrantFiled: October 10, 2018Date of Patent: August 10, 2021Assignee: Häfele Berlin GmbH & Co KGInventors: Rüdiger Walz, Peer Leistert, Gunter Nitschmann

Publication number: 20190345961Abstract: A tension connector connecting two components includes a bolt which has a bolt shaft and a bolt head. An eccentric lever has a bearing pot with a pot opening and with a pot interior which is formed as a pivoting bearing and by means of which the eccentric lever can be or is mounted on the bolt head so as to be pivotable about a pivot axis between a starting position and a tensioned position. The bearing pot has a slot for the bolt shaft, extending from the pot opening against the tensioning direction and, along the slot, has an outer contour which is eccentric relative to the pivot axis.Type: ApplicationFiled: July 25, 2019Publication date: November 14, 2019Inventors: Gunter Nitschmann, Gerd Sawatzki

Patent number: 10161432Abstract: A spreading connector for connecting two furniture parts, including a built-in pot having a pot bottom, the pot being pressable, pot bottom first, into a housing bore of a first of the furniture parts. The pot further has a hollow-cylindrical pot wall that has a wall opening and at least one spreading tab that is cut free in the hollow-cylindrical pot wall and is pivotable about an axis running tangentially to the hollow-cylindrical pot wall. A tightening element is rotatably mounted inside the built-in pot for tightening a fastening bolt of a second of the furniture parts which passes through the wall opening. The tightening element has an outer eccentric surface for spreading the at least one spreading tab. The at least one spreading tab has a free tab end that extends in an axial direction away from the pot bottom.Type: GrantFiled: April 21, 2014Date of Patent: December 25, 2018Assignee: HÄFELE GMBH & CO.
