Quick connect system and method for fluid devices
First Claim
1. A quick connect system comprising a first tubular member having a portion with a tapered external surface;
- a second tubular member having a portion with a tapered bore that receives the portion of the first tubular member in a telescoping relation;
at least one of the portions having a tapered locking surface; and
at least one clamp extending around at least a portion of the telescoping portions of the tubular members, the clamp having at feast one tapered locking surface;
the tubular members adapted to move relative to each other in an axial direction in response to fluid pressure therein to move the tapered locking surface of the clamp and the tapered locking surface of the at least one portion into engagement to lock the clamp against radial movement relative to the tubular members.

Abstract
A quick connect system and method for fluid devices according to which one end portion of a first tubular member is inserted in an end portion of a second tubular in a telescoping relationship. An arcuate clamp extends over the telescoping portions of the tubular members, and a tapered locking surface is formed on at least one of the tubular members and on the clamp. The tubular members move relative to each other in an axial direction in response to fluid pressure therein to move the tapered locking surfaces into engagement to lock the clamp against radial movement relative to the tubular members. A pipe assembly including a first connection system for connecting one end of a first pipe to one end of a second pipe while permitting relative rotation between the pipes, and a second connection system for connecting the other end of the first pipe to a third pipe so that rotation of the first pipe relative to the second pipe causes angular movement of the third pipe.

- a second tubular member having a portion with a tapered bore that receives the portion of the first tubular member in a telescoping relation;
- 12. A method of connecting two fluid flow devices, comprising the steps providing first tubular member on one of the flow devices, providing a second tubular member on the other flow device, tapering the external surface of an end portion of the first tubular member, tapering the internal surface of an end portion of the second tubular member, inserting the end portion of the first tubular member into the end portion of the second tubular in a telescoping relationship, positioning at least one arcuate clamp over the telescoping portions of the tubular members, forming a tapered locking surface on at least one of the tubular members, and forming at least one tapered looking surface on the clamp, the tubular members moving relative to each other in an axial direction in response to fluid pressure therein to move the at least one tapered locking surfaces of the clamp into engagement with the tapered locking surface of the at least one of the tubular members to lock the clamp against radial movement relative to the tubular members.
