Embodiment Construction

[0041] figure 1 and 1A An example coupling 10 according to the invention is shown. The coupling 10 comprises a plurality of segments, in this example two segments 12 and 14 are attached to each other end-to-end around a central space 16 . like figure 2 As shown in , each of segments 12 and 14 (12 shown) has a channel 20 extending between ends 22 and 24 of the segment. Each segment 12 and 14 also has first and second grooves 26 and 28 . Grooves 26 and 28 extend between segment ends 22 and 24 and are positioned on opposite sides of channel 20 in spaced relationship to each other. Each trench 26 and 28 is defined by two side surfaces 30 and 32 arranged in spaced relationship, and a base surface 34 extending between the side surfaces. like figure 2 and 3 As shown in , substrate surface 32 includes three surface portions 36 , 38 and 40 . First and second surface portions 36 and 38 are disposed at opposite ends 22 and 24 of segments 12 and 14, respectively. The third surf...

Abstract

A pipe coupling has segments attached end to end to define a central space that receives pipe elements inserted between the segments. The segments are supported on split rings received within grooves in each segment. The segments are supported in spaced relation in a preassembled state to permit insertion without disassembly of the coupling. The grooves in the segments have a floor surface with three surface portions. Two of the surface portions on each groove of each segment engage the split rings when the segments are supported in spaced relation.

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional application of, and claims priority to, US Provisional Patent Application No. 61 / 920,138, filed December 23, 2013, which provisional application is hereby incorporated by reference. technical field [0003] The present invention relates to mechanical pipe couplings for joining pipe elements in end-to-end relationship. Background technique [0004] Prior art mechanical couplings for joining pipe elements together end-to-end include interconnectable segments that can be positioned circumferentially around the sides of coaxially aligned pipe elements. end part. The term "tubular element" is used herein to describe any tubular object or member having a tubular form. Pipe elements include pipe handles, pipe fittings (such as elbows, caps, and tees), and fluid control components (such as valves, pressure reducers, filters, restrictors, pressure regulators, etc.). [0005] Each mechani...
