Abstract

A high-pressure, flexible, self-supportive piping assembly includes a jointed conduit formed by a plurality of ball and socket joint elements, a flexible internal conduit extending through the jointed conduit, an external sheath, and fittings at opposite ends which communicate with the internal conduit. The sheath is heat shrunk onto the jointed conduit. Each joint element has a ball at one end and a socket at an opposite end whereby the joint elements can be connected serially in end-to-end relationship to form the jointed conduit. The ball of one joint element frictionally engages the socket of the next joint element and, in combination with the stiffness of the external sheath, result in a piping assembly which can selectively configured in shape and which will tend to retain such a shape until subsequently configured.

Claims

1. A self-supporting conduit assembly comprising:

(a) an elongated jointed support having opposite ends and including a plurality of serially connected joint elements, each joint element being pivotable relative to an adjacent element through a limited angle of pivot, and each joint element frictionally engaging an adjacent joint element such that pivoting a joint element relative to an adjacent joint element is resisted by friction;

(b) an elongated flexible conduit having opposite ends and extending along said jointed support and engaging said jointed support at spaced intervals therealong;

(c) a first fluid fitting fluidically connected to a first end of said flexible conduit and being connected to a first end of said jointed support;

(d) a second fluid fitting fluidically connected to a second end of said flexible conduit and being connected to a second end of said jointed support; and

(e) a sheath shrink-fitted directly onto and conforming to the shape of the outside surface of said jointed conduit.

2. An assembly as set forth in claim 1 wherein:

(a) said jointed support is a jointed conduit and each of said jointed elements is tubular; and

(b) said flexible conduit extends substantially coaxially through said jointed conduit.

3. An assembly as set forth in claim 1 wherein:

(a) each joint element is pivotable about two axes of freedom with respect to an adjacent joint element.

4. An assembly as set forth in claim 1 and including:

(a) each joint element including a ball component at one end thereof;

(b) each joint element including a socket component at an opposite end from said ball component;

(c) a ball component of one joint element being received and retained in a socket component of an adjacent joint element;

(d) each joint element having at least two axes of pivotal freedom of movement relative to an adjacent joint element; and

(e) frictional engagement between a ball component of one joint element and a socket component of an adjacent joint element causing resistance of said pivotal freedom of movement between one joint element and an adjacent joint element.

5. An assembly as set forth in claim 1 wherein:

(a) said joint support and said flexible conduit cooperate to form a fluid carrying conduit assembly which is selectively configurable in shape and which retains said shape until subsequently reconfigured.

6. A self-supporting conduit assembly comprising:

(a) an elongated jointed conduit having opposite ends and including a plurality of serially connected, tubular joint elements, each joint element being pivotable relative to an adjacent joint element through a limited angle of pivot, and each joint element frictionally engaging an adjacent joint element such that pivoting a joint element relative to an adjacent joint element is resisted by friction;

(b) an elongated flexible conduit having opposite ends and extending in substantially coaxial relation through said jointed conduit;

(c) a first fluid fitting fluidically connected to a first end of said flexible conduit and being connected to a first end of said jointed conduit;

(d) a second fluid fitting fluidically connected to a second end of said flexible conduit and being connected to a second end of said jointed conduit; and

(e) an elongated flexible outer sheath extending between respective sets of said opposite ends of said jointed conduit and said flexible conduit and enclosing said jointed conduit and said flexible conduit therein, said sheath being shrunk-fit directly onto and conforming to the shape of the outside surface of said jointed conduit.

7. An assembly as set forth in claim 6 wherein:

(a) each joint element is pivotable about two axes of freedom with respect to an adjacent joint element.

8. An assembly as set forth in claim 6 and including:

(a) each joint element including a ball component at one end thereof;

(b) each joint element including a socket component at an opposite end from said ball component;

(c) a ball component of one joint element being received and retained in a socket component of an adjacent joint element;

(d) each joint element having at least two axes of pivotal freedom of movement relative to an adjacent joint element; and

(e) frictional engagement between a ball component of one joint element and a socket component of an adjacent joint element causing resistance of said pivotal freedom of movement between one joint element and an adjacent joint element.

9. An assembly as set forth in claim 6 wherein:

(a) said joint conduit and said flexible conduit cooperate to form a fluid carrying conduit assembly which is selectively configurable in shape and which retains said shape until subsequently reconfigured.

10. A self-supporting conduit assembly comprising:

(a) an elongated jointed conduit having opposite ends and including a plurality of serially connected, tubular joint elements, each joint element being pivotable relative to an adjacent joint element through a limited angle of pivot about two axes of pivotal freedom of movement relative to said adjacent joint element, and each joint element frictionally engaging an adjacent joint element such that pivoting a joint element relative to an adjacent joint element is resisted by friction;

(b) an elongated flexible conduit having opposite ends and extending in substantially coaxial relation through said jointed conduit;
