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: 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

Patent number: 11047415Abstract: An insert wedge is configured for fixedly clamping a first panel within a groove in a second panel. The insert wedge includes a square angle which has a broad limb and a wedge-like, narrow limb. A spring tongue is integrally formed on the outer side of the broad limb and extends by way of its free tongue end beyond the outer side of the narrow limb. The outer side of the narrow limb and the inner side of the broad limb may form an angle of 90°. The spring tongue may be inclined in relation to the inner side of the broad limb. The outer side of the narrow limb and the outer side of the spring tongue may form an angle of between 10° and 20°. The outer and/or inner side of the narrow limb and/or the outer side of the spring tongue may have projections.Type: GrantFiled: March 28, 2018Date of Patent: June 29, 2021Assignee: HÄFELE BERLIN GMBH & CO KGInventor: Peer Leistert
