Patent number: 11940073Abstract: The hose clamp described herein consists of a clamping band (10) with overlapping band sections in the closed state of the hose clamp, on which hooks (12, 19) are arranged for closing the hose clamp, and with a tightening device (15) arranged in the outer band section for tightening the hose clamp around an object to be clamped. The hooks (12, 19) are stamped out from the clamping band under cold working and each have a lug (21, 25). In the closed state of the hose clamp, the lug (21) of a hook (12) arranged on the inner band section and the lug (25) of a hook (19) arranged on the outer band section engage over each other, and the force is transmitted via transverse surfaces (27, 32) of the hooks (12, 19) that are in contact with each other.Type: GrantFiled: November 27, 2019Date of Patent: March 26, 2024Inventors: Markus Widrig, Andreas Vetter, Maxime Bösiger

Patent number: 10267344Abstract: A compression ring made of an initially open clamping band has ends which mutually engage in puzzle-like fashion for closing the compression ring. One band end carries a tongue which projects in the longitudinal direction of the band and has arms extending transversely to the longitudinal direction of the band, and the other end of the band is formed complementarily thereto. The transverse edges of the arms, which extend transversely to the longitudinal direction of the band and face the free end of the tongue, each have a convex part at the outer end and a concave part at the inner end.Type: GrantFiled: February 20, 2015Date of Patent: April 23, 2019Assignee: OETIKER SCHWEIZ AGInventors: Markus Widrig, Manuel Muller

Patent number: 6588093Abstract: In a manufacturing method and apparatus for manufacturing sheet metal packets in punch-packeting technology with a round or oval iron cross section. laminations are punched from a ribbon and are provided with depressions at one side and with elevations at the other side that coincide with the depressions and lie opposite them, with the elevations being in the form of at least two circular nipples being pressed into the depressions upon assembly of each packet. In one lamination per packet, serving as a separating lamination, cylindrical holes are punched instead of the depressions, the nipples of the neighboring lamination engaging into these holes. Laminations are thereby punched from the strip that respectively exhibit different outside contours, particularly different widths, and are joined with one another to form a packet that has a cross-section that is at least partially round, by virtue of the sheet metal packet having graduated edges.Type: GrantFiled: March 17, 2000Date of Patent: July 8, 2003Assignees: Vacuumschmelze GmbH, FAES Werkzeug-und-Maschinenbau AktiengesellschaftInventors: Kurt Emmerich, Alois Hangg, Herbert Hein, Markus Widrig, Jörg Lüscher
