Fitting with draw mechanism
First Claim
1. A fitting, comprising:
- a hollow body that includes an opening at a first end;
a sealing member positioned on an interior surface of the hollow body;
a draw mechanism including a primary actuation element coupled with the hollow body at the first end, and a plurality of secondary actuation elements coupled to the sealing member, the plurality of secondary actuation elements positioned in an interior of the hollow body and circumferentially spaced from each other, the plurality of secondary actuation elements engaged with the primary actuation element such that actuation of the primary actuation element draws the plurality of secondary actuation elements axially towards the opening at the first end of the hollow body, thereby translating the sealing member from an open position to a sealing position;
wherein the primary actuation element includes a plurality of sloped surfaces and each one of the secondary actuation elements is engaged with a respective one of the plurality of sloped surfaces.

Abstract
A fitting includes a hollow body, a sealing member, and a draw mechanism. The fitting mechanism includes a primary actuation element coupled with the body at a first end, and a plurality of secondary actuation elements coupled to the sealing member. The plurality of secondary actuation elements are positioned in an interior of the hollow body and circumferentially spaced from each other. The plurality of secondary actuation elements are also engaged with the primary actuation element such that actuation of the primary actuation element draws the plurality of secondary actuation elements axially towards the opening at the first end of the hollow body thereby translating the sealing member from an open position to a sealing position.

10. A fitting, comprising:
-
a hollow body that includes an opening at a first end; a sealing member positioned on an interior surface of the hollow body; a draw mechanism including a primary actuation element coupled with the hollow body at the first end, and a plurality of secondary actuation elements coupled to the sealing member, the plurality of secondary actuation elements positioned in an interior of the hollow body and circumferentially spaced from each other, the plurality of secondary actuation elements engaged with the primary actuation element such that actuation of the primary actuation element draws the plurality of secondary actuation elements axially towards the opening at the first end of the hollow body, thereby translating the sealing member from an open position to a sealing position; wherein the first end of the hollow body includes a plurality of circumferentially spaced tapered tabs that converge towards a longitudinal axis at the first end, adjacent ones of the tabs being separated in the first circumferential direction by longitudinally extending slots and wherein the secondary actuation members each extend through a respective one of the longitudinally extending slots. - View Dependent Claims (11, 12, 13, 14)

15. A fitting, comprising:
-
a hollow body that includes an opening at a first end; a sealing member positioned on an interior surface of the hollow body; a draw mechanism including a primary actuation element coupled with the hollow body at the first end, and a plurality of secondary actuation elements coupled to the sealing member, the plurality of secondary actuation elements positioned in an interior of the hollow body and circumferentially spaced from each other, the plurality of secondary actuation elements engaged with the primary actuation element such that actuation of the primary actuation element draws the plurality of secondary actuation elements axially towards the opening at the first end of the hollow body, thereby translating the sealing member from an open position to a sealing position; wherein the primary actuation element is rotatably coupled with the hollow body at the first end and rotation of the primary actuation element in a first circumferential direction with respect to a longitudinal axis of the hollow body draws the plurality of secondary actuation elements axially towards the opening at the first end of the hollow body, thereby dragging the sealing member from an open position to a sealing position. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A fitting, comprising:
-
a hollow body that includes an opening at a first end; an annular sealing member positioned on an interior surface of the hollow body; and an actuation mechanism configured to draw the sealing member axially towards the first end of the hollow body and radially inward towards a longitudinal axis of the hollow body by actuating at least one bolt that is coupled to the hollow body and the actuation mechanism, the at least one bolt extending substantially transverse to the longitudinal axis of the hollow body; and a plurality of restraining elements circumferentially arranged on the interior surface of the hollow body, the plurality of restraining elements being arranged axially between the sealing member and the first end of the hollow body.

23. A fitting, comprising:
-
a hollow body that includes an opening at a first end; an annular sealing member positioned on an interior surface of the hollow body; and an actuation mechanism configured to draw the sealing member axially towards the first end of the hollow body and radially inward towards a longitudinal axis of the hollow body by actuating at least one bolt that is coupled to the hollow body and the actuation mechanism, the at least one bolt extending substantially transverse to the longitudinal axis of the hollow body; wherein the actuation member includes a ring rotatably mounted to the hollow body and a plurality of follower elements, and each of the follower elements are coupled to the annular sealing ring, and wherein the at least one bolt is coupled to the ring such that actuating the at least one bolt causes the ring to rotate in a circumferential direction with respect to the hollow body, and the plurality of follower elements engage the ring such that rotation of the ring causes the plurality of follower elements to translate towards the first end of the hollow body. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
