Abstract
Abstract An over-the-center toggle mechanism for actuating locking dogs for connecting and disconnecting two underwater members. The first member includes a locking notch and the second member slideably carries locking dogs for transverse movement for engagement and disengagement with the locking notch. A toggle linkage includes a first pivot connection connected to the dogs and a second pivot connection longitudinally actuated by a piston whereby longitudinal movement of the second pivot connections transversely moves the locking dogs. A resilient load spring acts against the second pivot connections and towards said first pivot connections for locking the second pivot connections in a past dead center position relative to the first pivot connections. The second member includes a tubular body having an annular cavity with a longitudinally reciprocal carriage mounted in the cavity and actuated by the piston. The second pivot connections and the spring are transversely movable on the carriage and carried by the carriage. Preferably the cavity includes seals for sealingly enclosing the cavity and includes a flexible member exposed on one side to the interior of the cavity and on the second side to the exterior of the cavity for compensating for a difference in fluid pressure between the cavity and the outside of the body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
In a connector for connecting and disconnecting two members in which the first member includes a first locking means and the second member includes a double acting longitudinally moving piston for moving a second locking means into and out of locking engagement with said first locking means, the improvement of a locking toggle mechanism comprising, said second locking means slideably carried by the second member for transverse movement toward and away from said second member for engagement and disengagement with said first locking means, and a toggle linkage having a first pivot connection connected to the second locking means and a second pivot connection longitudinally actuated by the piston whereby the longitudinal movement of the second pivot connection transversely moves said second locking means and moves the second pivot connection into a past dead center locking position.
Claim 2
Dependent Claim
137 words
In a connector for connecting and disconnecting two members in which the first member includes a first locking means and the second member includes a double acting longitudinally moving piston for moving a second locking means into and out of locking engagement with said first locking means, the improvement of a locking toggle mechanism comprising, said second locking means slideably carried by the second member for transverse movement toward and away from said second member for engagement and disengagement with said first locking means, and a toggle linkage having a first pivot connection connected to the second locking means and a second pivot connection longitudinally actuated by the piston whereby the longitudinal movement of the second pivot connection transversely moves said second locking means and moves the second pivot connection into a past dead center locking position.
Claim 3
Dependent Claim
40 words
The apparatus of claim 1 including, a resilient load spring acting against the second pivot connection and towards the first pivot connection for locking said second pivot connection in a past dead center position relative to said first pivot connection.
Claim 4
Dependent Claim
155 words
A connector for locking a second member to a first member which includes a first locking means comprising, said second member including an annular body having an annular cavity, second locking means slideably carried by the body for transverse movement toward and away from said second member for engagement and disengagement with the first locking means, said second locking means extending into said cavity, a toggle linkage in said cavity, which includes first and second pivot connections, said first pivot connection being connected to said second locking means; a longitudinally reciprocative carriage mounted in the cavity, said carriage carrying said second pivot connection, an annular spring carried by the carriage and acting against said second pivot connection and towards said first pivot connection for locking said second pivot connection in a past dead center position relative to said first pivot connection, and a double acting longitudinally movable means connected to and longitudinally moving said carriage.
Claim 5
Dependent Claim
155 words
A connector for locking a second member to a first member which includes a first locking means comprising, said second member including an annular body having an annular cavity, second locking means slideably carried by the body for transverse movement toward and away from said second member for engagement and disengagement with the first locking means, said second locking means extending into said cavity, a toggle linkage in said cavity, which includes first and second pivot connections, said first pivot connection being connected to said second locking means; a longitudinally reciprocative carriage mounted in the cavity, said carriage carrying said second pivot connection, an annular spring carried by the carriage and acting against said second pivot connection and towards said first pivot connection for locking said second pivot connection in a past dead center position relative to said first pivot connection, and a double acting longitudinally movable means connected to and longitudinally moving said carriage.
Claim 6
Dependent Claim
55 words
The apparatus of claim 3 including seals for sealing and enclosing said cavity, and a flexible member exposed on one side to the interior of the cavity and on the second side to the exterior of the cavity for compensating for a difference in fluid pressure between the cavity and the outside of the body.
Claim 7
Dependent Claim
19 words
The apparatus of claim 3 wherein said second pivot connections and said spring are transversely movable on said carriage.
Claim 8
Dependent Claim
191 words
A hydraulically actuated connector for locking a second member to a first member which includes a first locking means comprising, said second member including a tubular body for telescoping over the first member and including an annular sealed cavity, second locking means slideably carried by the body for transverse movement toward and away from said second member for engagement and disengagement with said first locking means, said second locking means extending into said cavity, a toggle linkage in said cavity, which includes first and second pivot connections, said first pivot connection being connected inside of the cavity to said second locking means, an annular longitudinally reciprocative carriage mounted in the cavity and bearing on its inside against the inside of the body, said carriage carrying said second pivot connection, an annular spring carried by the carriage and acting against said second pivot connection and towards said first pivot connection for locking said second pivot connection in a past dead center position relative to said first pivot connection, and a double acting longitudinally movable piston carried by the body and extending into the cavity and connected to and longitudinally moving said carriage.
