Publication number: 20230031943Abstract: The invention relates to a two-part hinge device for a door or a window, comprising a first housing part (20) and a second housing part (30), which in the assembled state form a door hinge housing (19), and a rod (15) which extends in the first housing part (20) and second housing part (30) along the axial direction (60) thereof, wherein the rod (15) has at least three successive—a first, a second and a third—rod sections (16, 17, 18). The first rod section (16) is supported in the first housing part (20) by a clamping element (50), and the third rod section (18) supports the second housing part (30). In the region of the second rod section (17), the rod (15) is adjustable relative to the first housing part (20) in two directions at an angle to each other and independently of each other, and the two directions at an angle to each other are arranged transversely to the axial direction (60) of the rod (15).Type: ApplicationFiled: August 10, 2022Publication date: February 2, 2023Inventors: Martin HOFFMANN, Julian STURM, Dominik EGGERT, Nico SPINELLI, Uwe WERNER, Marco ZÄCH, Stefan BRUNNSCHWEILER, Ivo LENHERR

Patent number: 10240626Abstract: A method of producing fastening assembly (10) including a series of layers (12, 14, 16) and a screw (18), the screw (18) having a screw head (20), a shaft (24), a thread (26) extending into a displacement tip (22) and an unthreaded shaft portion (28). The method includes screwing the screw (18) into the series of layers (12, 14, 16), the layer (14) in the series of layers (12, 14, 16) that is furthest from the screw head (20) being deformed in the screw-in direction, so that a thickness Dp of the series of layers (12, 14, 16) is increased in a region around the screw (18), and continuing to screw in the screw (18) until the screw head (20) strikes the series of layers, a maximum thickness Dp, max of the series of layers being reached at this moment and the length LF of the unthreaded shaft portion (28) being up to 10% less than and up to 30% greater than the maximum thickness Dp, max of the series of layers.Type: GrantFiled: January 19, 2015Date of Patent: March 26, 2019Assignee: SFS intec Holding AGInventors: Roland Mair, Marco Zach

Patent number: 10221880Abstract: A self-drilling screw composed of an austenitic or some other non-corrosive base material (1) is provided, having a shank (12), having a cutting or shaping drilling or threaded tip (16) arranged at one shank end and having a hard coating (3) applied at least to the drilling or threaded tip (16) by electrodeposition, this hard coating (3) having a layer containing a transition metal, for example a hard chromium layer. The shank (12) has a hard edge layer (2) at least under the hard coating (3). A topcoat (4) composed of a lubricating and heat-dissipating material, which preferably is metal, wax and/or lacquer, is applied to the hard coating (3).Type: GrantFiled: August 10, 2015Date of Patent: March 5, 2019Assignee: SFS intec Holding AGInventors: Marco Zach, Rene Dutler, Ralf Steyer

Publication number: 20160327081Abstract: A screw (10) having a screw head (14) equipped with an engagement portion (12), having a shaft (16) which defines a screw axis and which bears a thread (18), and having a thread-free shaft portion (20) arranged between the thread (18) and the screw head (14). A head-side end (22) of the thread (18) is truncated. Additionally, the thread (18) ends, adjacent to the thread-free shaft portion (20), in an end plane (32) which, with a constant spacing to the screw head (14), runs at least partially around the shank (16) and forms an angle ?E with the screw axis, and a head-side flank (34) of the thread (18) averted from the thread-free shank section (20) forms an angle ?F with the screw axis, and the angle ?E is smaller than the angle ?F.Type: ApplicationFiled: January 19, 2015Publication date: November 10, 2016Applicant: SFS intec Holding AGInventors: Roland Mair, Marco Zach

Patent number: 9194416Abstract: A self-drilling screw made of an austenitic or other stainless steel, is provided having a drilling tip. The shank is integrally formed of an austenitic or other stainless steel and has a galvanically applied thin coating at least in the tip region, with the coating being harder than a non-coated region. The thin coating has a pearl-like or columnar surface, a coating thickness of at least 2 ?m and a hardness in a range of from 500 to 1500 HV0.3. The self-drilling screw can be produced more simply than a typical self-drilling screw, in which the drilling tip consists of a harder material than the shank and is welded to the shank made of stainless steel. The coating ensures the drilling capacity and thread formation.Type: GrantFiled: May 2, 2013Date of Patent: November 24, 2015Assignee: SFS intec Holding AGInventors: Marco Zach, Peter Schmid, Rene Dutler
