Quick connect-disconnect coupler

Claim 1

Coupling means comprising cooperative male and female elements adapted to be coupled together by relative and successive axial and rotational movement, said female element includes a saddle-like portion having a surface adapted to at least partially embrace a conduit, said female element includes a tubular portion of a size to receive said male element, said tubular portion projects away from said saddle-like portion surface and in the same facing direction thereof thereby being adapted for insertion into a transverse opening of a conduit, means defining an annular shoulder on each element, said shoulders being in axially opposed relationship, resilient gasket means seated between said shoulders, cooperative means for axially moving said shoulders toward each other upon relative rotation of said elements toward the coupled position thereof, said cooperative means are cam and cam follower means of said female and male elements respectively, said cam means is defined by a terminal annular end surface of said tubular portion most remote from said saddle-like portion and facing in an axial direction away from saddle-like portion, and said terminal annular end surface is inclined circumferentially whereby said annular shoulders are moved axially with said gasket therebetween being compressed to form a seal between said male and female elements in the coupled condition thereof.
