Patent number: 7823930Abstract: A coupling comprising a receiving part (1), a securing part (9) and an insertion part (17) includes blocking elements (6, 13?) whose engagement preventing the securing part (9) from moving from an extended position into a retracted position is released by the axial displacement of latching arms (13) of the securing part (9) under the effect of a retaining ring (22) upon the insertion of said insertion part (17), such that when the insertion part (17) is properly arranged in a receiving space (16) of the receiving part (1), the securing part (9) can be shifted into the retracted position in which said insertion part (17) is secured. What is achieved in this way is relatively simple modification of the assembly force through design measures, high wear resistance, and simple and operationally reliable manipulation of the inventive coupling with regard to the release of the connection between the receiving part and the insertion part, especially under confined spatial conditions.Type: GrantFiled: October 13, 2005Date of Patent: November 2, 2010Assignee: A.

Patent number: 7651138Abstract: A coupling for a fluid conducting system comprises an elongated coupling part (1) and a locking part (20), which can be displaced in a direction perpendicular to the longitudinal direction and which can be mounted on the coupling part (1) in a manner that enables it to slide. The guiding of the locking part (20) ensues via detent elements (24, 25) that engage inside guide recesses (13) of the coupling part (1). The locking part (20) can be fixed in a releasing position or in a locking position by the engagement of detent projections (26, 27) inside releasing recesses (18, 19) or inside locking recesses (16, 17). This enables a relatively problem-free operating of the coupling during opening and closing.Type: GrantFiled: March 17, 2005Date of Patent: January 26, 2010Assignee: A.

Patent number: 7549677Abstract: A device for sealingly linking two end pieces (24) of a fluid line system, comprises a casing part (1) and an inner part (13). The inner part (13) is arranged in a prefabricated arrangement within the casing part (1) in an axially displaceable manner and serves to fixate a sealing unit (21) that is detachably linked with the inner part (13) until an end piece (25) is inserted into the casing part (1) via an introduction area (3) and comes into contact with the inner part (13). When the end piece (25) is inserted, the inner part (13) is axially expelled from the casing part (1), whereby the sealing unit (21) is inhibited in its axial movement by an abutment (12) and remains within the casing part (1). The two end pieces can be sealingly linked while indicating the relative position of the end piece (25) coming into contact with the inner part (13) without requiring a separate handling of the sealing unit (21).Type: GrantFiled: June 10, 2004Date of Patent: June 23, 2009Assignee: A.

Patent number: 7445249Abstract: The invention relates to a coupling comprising a receiving part (1) and a fixing part (10), which have a blocking assembly (15, 16, 17). If the insertion part has not been introduced into the receiving part (1) correctly, elements (15, 16, 17) of the blocking assembly that are configured on the receiving part (1) and on the fixing part (10) engage with one another in such a way that the fixing part (10) is prevented from being retracted from the extended position. Arms (11, 12) of the fixing part (10) are configured in such a way that when a retaining ring of the insertion part is positioned in the vicinity of said arms (11, 12), the engagement of the elements (15, 16, 17) of the blocking assembly is released and the fixing part (10) can be displaced into the retracted position to engage behind the retaining ring by means of the retraction section. This permits an efficient mounting operation.Type: GrantFiled: November 25, 2004Date of Patent: November 4, 2008Assignee: A. Raymond & CIEInventors: Axel Feger, Michael Trede

Patent number: 6089616Abstract: An indicator device for use with a detachable plug assembly includes a pair of spaced apart rings joined together by a pair of elongated connecting portions. The connecting portions extend in an axial direction between the rings. The connecting portions each have a outwardly curved bridging strip portion extending between a pair of flexible webs. The rings are mounted between the plug housing and the flange on the tubular insert member so that the bridging strips bulge outwardly to form a loop when the insert member is fully inserted into the plug to indicate that the insert member is properly locked within the plug. The indicator device may be connected either to the plug housing or to the insert member prior to assembly.Type: GrantFiled: December 16, 1998Date of Patent: July 18, 2000Assignee: A.

Patent number: 6082779Abstract: A releasable connector for connecting tubing such as used in fuel lines has a display member to indicate when positive locking has occurred. The display member member is attached to the outside of the housing of the connector. The display member has a strap supporting a cover portion. The cover portion has a pair of resilient flanges which are insertable into an opening in the housing of the connector. The flanges extend into a chamber to engage an annular ring of a conventional male tube end. The annular portion of the tube end displaces the flanges of the display member after passing through a locking member contained in the housing of the connector. In this way, the tamper indicator indicates that the tube end has been positively received in the locking position.Type: GrantFiled: February 27, 1998Date of Patent: July 4, 2000Assignee: A.
