Abstract: A seal for a coupling joining pipe elements has angularly oriented ramp surfaces on an outer surface. The ramp surfaces are arranged in diametrically opposite pairs which are positioned at the three o'clock and nine o'clock positions at the interface between segments forming the coupling. The ramps are expected to mitigate pinching of the seals between the segments as the segments are drawn together, compressing the seals to form a fluid tight pipe joint.

Abstract: A mechanical coupling for joining pipe elements has segments joined end to end, each segment having a pocket of varying depth for receiving a ring gasket. The varying depth of the pocket is used to control the distortion of the ring gasket between a round shape and a non-round shape when the segments are arranged in spaced apart relation around the ring gasket, the spacing between the segments being sufficient to permit insertion of the pipe elements without disassembly of the coupling.

Abstract: A pipe coupling with an anchoring arrangement for locking the pipes together axially is described. The anchoring arrangement comprises a tubular casing (10), a frusto-conical gripping ring (40) with inwardly projecting gripping teeth 42 and tensioning bolts (17) for tightening the casing (10) about the frusto-conical gripping ring (40). The frusto-conical gripping ring (40) is formed of a plurality of arcuate segments (40a) and (40b) which overlap to form a complete ring. By forming the gripping ring of segments, the gripping ring is able to adapt to pipes that are not truly circular in cross section and a better grip on the pipe may be achieved than with a single-piece gripping ring.

Abstract: The invention relates to a system (14) for connecting two pipes (10), especially the pipes of a sprinkler system. The inventive system comprises an annular housing (16) that peripherally encloses the pipes (10) to be connected in a pressure-tight manner in the zone of their adjoining front faces, and a sealing element (32) that seals the housing (16) with regard to the pipes. The aim of the invention is to achieve a reliable and tight connection with an as simple a construction as possible that also protects the system (14) from being displaced with regard to the pipes (10) in an uncontrolled manner. To this end, at least two annular securing elements (52) are disposed in the housing (16), said elements being correlated with one pipe (10) each and being provided with at least one projection on the pipe end and interacting with the respective pipe (10). The sealing element (32) disposed in the housing (16) extends between said securing elements with at least two sections or with two elements of which it consists, one of said sections or elements sealingly contacting one of the pipes.

Abstract: Coupling segments (12, 14) having angled end faces (16a, 16b) are provided with stop members (30, 32) at their respective ends which prevent misalignment of the coupling segments (12, 14) during their assembly onto the adjacent ends of pipes or fittings. The stop members (12, 14) being crushed down during final tightening of the coupling to permit further limited lateral movement of the ends of the coupling segment (12, 14), thus to provide a truly ridged coupling in which angling of the axes of the respective pipes or fittings is eliminated.

Abstract: A clamping device includes a base element, a first clamping arrangement moveably mounted with respect to the base element, and a second clamping arrangement moveably mounted with respect to the base element. The first clamping arrangement is configured for providing a coupling displacement along a coupling axis responsive to an actuation displacement being applied to the first clamping arrangement along an actuation axis, the actuation axis being non-parallel with respect to the coupling axis. The second clamping arrangement is configured for providing an output displacement along an output axis responsive to the coupling displacement being applied to the second clamping arrangement along the coupling axis, the output axis being non-parallel to the coupling axis.
