Publication number: 20190257452Abstract: The clamping clip described here includes a clamping band the two end portions of which overlap each other in the closed condition of the clamping clip. A tongue disposed on the overlapped inner band portion is received by a tongue channel provided on the overlapping outer band portion, the shape of the tongue channel being complementary to the shape of the tongue. The tongue has a root part in which the tongue width, measured in the axial direction of the clamping clip, decreases from the full clamping band width to a smaller value, and an end part adjoining the root part, in which the tongue width constantly has the smaller value.Type: ApplicationFiled: July 11, 2017Publication date: August 22, 2019Inventors: Willi Haensli, Rolf Deller, Steffen Richter

Patent number: 10267442Abstract: A diameter variable hose clamp includes a clamping band having end portions which mutually overlap in the closed condition of the hose clamp. The inner end portion carries a tongue which has a width smaller than the full width of the clamping band, and hooks for closing of the hose clamp. The outer end portion is provided with openings for receiving the hooks, an ear-like tightening device for tightening the hose clamp around an object to be clamped, and an arcuate band portion for receiving the tongue. The arcuate band portion is cut free from the clamping band by longitudinal cuts in forming lateral band webs.Type: GrantFiled: July 3, 2015Date of Patent: April 23, 2019Assignee: Oetiker Schweiz AGInventors: Manuel Mueller, Willi Haensli, Klaus Schwaiger

Patent number: 9816654Abstract: In a rapid coupling, a pipe nipple engages a through hole of a socket. A first annular groove provided on the pipe nipple serves to catch a locking ring provided in the socket, in order to lock the coupled condition. A sleeve is movable on the pipe nipple, the sleeve having an inner projection to be retained by the first annular groove of the pipe nipple in a pre-assembled condition. When the pipe nipple is inserted into the socket, the sleeve abuts the socket and is then moved along the pipe nipple until the inner projection is caught by a second annular groove if the coupling is properly locked. It the pipe nipple is not moved into the socket to such an extent that the locking ring is caught by the first annular groove, the second annular groove remains visible outside the sleeve to indicate the improper coupling condition.Type: GrantFiled: October 17, 2014Date of Patent: November 14, 2017Assignee: Oetiker Schweiz AGInventors: Willi Hänsli, Urs Müller

Patent number: 8424167Abstract: Connecting the two band ends 10, 18 of a hose clamp is done by means of a guide hook 16 disposed on an inner band portion and engaging a guide hook receiving means 12 on the outer band end 10, and a support hook 17 also formed on the inner band portion and engaging a support hook receiving means 13 on the outer band portion. The support hook receiving means 13 is an embossment formed from the band material by cold deformation and being continuous with the band material on all sides, the inner surface of the support hook receiving means 13 having a support portion 25 adjacent to the outer band end 10 and extending at right angles with respect to the band surface. The support hook 17 has a nose 26 which faces away from the inner band end 18 and has a cut edge which nicks into the support portion 25 of the support hook receiving means 13 when the hose clamp is tightened.Type: GrantFiled: June 18, 2008Date of Patent: April 23, 2013Assignee: Hans Oetiker AG Maschinen-und ApparatefabrikInventors: Ulrich Meier, Willi Haensli
