Pipe attachment

摘要

A pipe attachment for sealing a leak, the attachment comprising a frame formed by a pair of opposed jaws which when closed define a substantially cylindrical cavity, and a stretchable waterproof membrane secured to the frame; wherein each jaw has a distal end and the frame comprises an intermediate portion located between said opposed distal ends, said jaws having a closed configuration in which said distal ends of the jaws are adjacent to each other, and an open configuration in which said distal ends of the jaws are spaced apart from each other; the frame including a securing means for resisting the opening of the jaws in said closed configuration; and wherein the stretchable waterproof membrane includes opposed end portions, each of said membrane end portions being secured to the distal end portion of a respective jaw and said stretchable waterproof membrane being secured to the frame only via said end portions; the stretchable waterproof membrane having an unstretched configuration when the cavity is empty and the jaws are closed in which it is spaced from said intermediate portion of the frame and a stretched configuration when a pipe is located within the cavity in which it is urged towards the intermediate portion by said pipe and is stretched around said pipe.

1. A pipe attachment for sealing a leak, the attachment comprising a frame formed by a pair of opposed frame elements and a stretchable waterproof membrane permanently fixed to the frame elements such that said frame is capable of defining a substantially cylindrical cavity; wherein each frame element defines an end of the frame and said stretchable membrane defines an intermediate portion located between said opposed ends, said frame having a closed configuration in which said frame elements of the frame are adjacent to each other, and an open configuration in which said frame elements of the frame are spaced apart from each other; said frame including a securing means for resisting the opening of said frame elements in their closed configuration; and wherein said stretchable waterproof membrane is formed from an elastomer and includes opposed end portions, each of said membrane end portions being permanently fixed to a respective one of the frame elements, and said stretchable waterproof membrane being secured to the frame elements only via said end portions; said stretchable waterproof membrane having an unstretched configuration and a stretched configuration when a pipe is located within said defined cylindrical cavity and said membrane is stretched around said pipe.
