PIPE COUPLING

摘要

A pipe coupling for connecting adjacent pipes. The pipe coupling has a connection type at each end that may be male or female. A female end may have an interior surface defining a receiving chamber. An interior circumferential groove is formed in the interior surface in which a band is seated. A plurality of rigid fingers is extends from the band into the receiving chamber. The receiving chamber receives a male end of an adjacent pipe, the male end having an exterior surface. An exterior circumferential groove is defined on the exterior surface to receive the plurality of rigid fingers. A variety of connection types and combinations are disclosed. The female end may define a sight window to permit viewing of the position of a male end of an adjacent pipe. The receiving chamber may have a reduced diameter proximate to the middle of the coupling to improve sealing.

主权项

1. A pipe coupling for connecting adjacent pipes, comprising:
a first end of a body of the pipe coupling comprising a first connection type; a second end of a body of the pipe coupling opposite from, integral with, and seamless with the first end and comprising a second connection type, wherein the second connection type comprises:
a female end with an interior surface, a thickness, and a female leading edge terminating the female end of the coupling, the interior surface of the female end defining a receiving chamber;at least one interior circumferential first groove formed in the interior surface of the female end;a band seated within the at least one circumferential first groove; anda plurality of rigid fingers formed continuously with and extending from the band into the receiving chamber at an acute angle directed away from the female leading edge, the plurality of rigid fingers being displaceable.
