Title: PRE-ASSEMBLED PIPE COUPLING WITH AN INSERTION BOUNDARY FOR AXIAL RECEIPT OF PIPE ENDS
Abstract:
A pre-assembled pipe coupling (10) includes a gasket (200), a housing (12) surrounding the gasket, and a fastener (20). The housing has three segments sequentially coupled to each other to define an insertion boundary (11). A bridge segment (12c) has a first mount (18) extending lateral from the wall and having a plurality of first lateral walls defining a first aperture (22) and a second mount (18) having a plurality of second lateral walls defining a second aperture (22). A first clamp segment (12a) has a first hook (14) disposed in the first aperture. A second clamp segment (12b) has a second hook (14) disposed in the second aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture. The fastener has an adjusted length at which the first clamp segment grips the gasket, and the second clamp segment grips the gasket to locate the first sealing lip and the second sealing lip within the insertion boundary.
