When the plug-in part is inserted into the receiving part, a spring-elastic securing element, which is fitted captively and in a prestressed manner as a spring force store on the receiving part in a pre-assembly position, is displaced by the plug-in part relative to the receiving part in such a way that, when the final assembled position is reached, its stored spring force is released by the joining movement itself and the securing element latches in a force-fitting manner between bearing surfaces of the receiving part and of the plug-in part.Type: ApplicationFiled: March 25, 2009Publication date: April 15, 2010Inventor: Norbert Spielmann

Patent number: 7695024Abstract: Coupling for connecting of pipe shaped sections comprising a first pipe section and a coupling device arranged to connect the first pipe section with a second pipe section. When joined together, the first pipe section is arranged to receive the second pipe section in such a way that the first pipe section and the second pipe section forms an overlapping region. The wall of the first pipe section is provided with a through hole in the overlapping region and the coupling device is adapted to protrude through the hole. The coupling device is at least at one of its ends slidably attached in such a way that a rotational displacement around, and essentially perpendicular to, the axial direction of the pipe section will give rise to a change between a first position for locking, wherein said coupling device is protruding on the inner side of the first pipe section, and a second position for release wherein the coupling device essentially not is protruding.Type: GrantFiled: September 29, 2006Date of Patent: April 13, 2010Assignee: ITW Sverige ABInventors: Kristian Ostergren, Akemi Conradsson

Patent number: 7631904Abstract: A pipeline plug-in connection (10) has a receiving part (14), a plug-in part (16) which can be plugged into the receiving part (14), a sealing element (18) for sealing between the receiving part and the plug-in part, and an elastic securing element (20). The plug-in part has a pipe section (50) with an abutment (24) with an expanding diameter section (26) which expands in terms of its external diameter counter to the joining direction, over which expanding diameter section the securing element can be stretched, and an abutment face (28), behind which the securing element can latch. The expanding diameter section ends, with its largest external diameter substantially near or at the abutment face, wherein a flange (54) is formed on the pipe section, the flange forming a sealing face (56) at the end, against which sealing face the sealing element bears in a sealing manner when the plug-in connection is assembled.Type: GrantFiled: September 12, 2005Date of Patent: December 15, 2009Assignee: FTE automotive GmbHInventors: Heiko Heim, Egid Macht, Karl Redai, Helmut Stubenrauch

Patent number: 7631906Abstract: A removable plug-in connection for high-pressure lines, in particular brake lines in the construction of motor vehicles. The connection includes a cylindrical receiving housing (1) with a central receiving chamber (2), in addition to a tubular plug-in part, which is equipped with a peripheral retaining rib. An insertion side of the receiving housing (1) has an enlarged receiving chamber (2) in which several radially guided locking elements (5) can be retained, the elements being clamped in a direction of the interior by a retaining ring (14). The locking elements (5) include two half-shells (8) that include retainer wedges (18) that point inwards, engaging behind the retaining rib (4) in a positive fit once the plug-in part (3) has been inserted. Each half-shell (8) has a projecting centering pin on one end face, the pin constituting an extension of the internal wall and engaging in a corresponding cavity on the opposing end face when the two half-shells (8) are assembled.Type: GrantFiled: January 27, 2004Date of Patent: December 15, 2009Assignee: A. Raymond & CieInventors: Erminio Moretti, Daniel Martin-Cocher, Albert Raymond

Patent number: 7614666Abstract: An end section of a plastic fluid line with a push-in fitting is injection molded on coaxially for sealed push-in connection to a mating element of complementary shape with the aid of a securing element which transmits axial forces. The assembly formed of an end section and push-in fitting has a first circumferential groove on the end section, in the region of which the push-in fitting is molded on with form-fitting penetration of the plastic of the push-in fitting into the first circumferential groove. The end section, in the joining direction of the push-in fitting, protrudes axially beyond the latter and has a second circumferential groove for receiving a sealing ring. A third circumferential groove for receiving the securing element is molded into the push-in fitting on the outer circumference thereof.Type: GrantFiled: March 9, 2006Date of Patent: November 10, 2009Assignee: FTE automotive GmbHInventors: Uwe Eggert, Heiko Heim, Martin Kollmann, Jochen Schneier

Patent number: 7611170Abstract: A hose having a compressible wall which is adapted to be connected at one end thereof to a nozzle of a sprayer. The other end is attached to a stub pipe or stem extending from a tank of the sprayer which can contain a pressurized liquid which flows through the hose and is sprayed via the nozzle. The coupling provides a quick connection for the hose to the pipe stem and also allows the coupling/hose assembly to freely rotate 360° while remaining sealed. The coupling is an assembly of a nipple and a sleeve retainer having a throat which compresses the hose wall and provides a retainer, retaining the end of the hose on the nipple. A spring clip is sprung apart as the assembly of retainer, nipple, and hose is seated on the pipe stem. To disconnect or release the coupling, the spring clip is spread apart to free the assembly.Type: GrantFiled: September 26, 2006Date of Patent: November 3, 2009Assignee: Chapin Manufacturing, Inc.Inventor: Donald R.

Patent number: 7597362Abstract: A plug-in connector for tube and hose lines includes a nozzle with a catch shoulder extending around at least a part of the outer circumference. The catch shoulder is formed by an inclined surface with a slope that increases from the outer circumference and a catch surface following in the insertion direction. A plug may be latched to the catch surface of the nozzle by at least two spaced-apart latching locations and supports a radially-displaceable, essentially U-shaped catch spring having two lateral legs formed as catch legs. Both latching locations of the catch spring can latch reliably and simultaneously, even if the nozzle is inserted into the plug at an angle, by forming the catch spring with at least one additional approximately centered latching location disposed between the plug and the nozzle. The additional latching location is located forward of the two lateral latching locations in the insertion direction.Type: GrantFiled: February 24, 2004Date of Patent: October 6, 2009Assignee: Henn GmbH & Co.
