Abstract
A locking dog assembly including a body including inner cavity with a lower opening, a first locking dog at least partially extending through a first side of the body and displaceable into and out of the inner cavity, a second locking dog at least partially extending through a second side of the body, opposite the first side, and displaceable into and out of the inner cavity, and a mechanism for simultaneous displacement of the first and second locking dogs with mechanical advantage.
Claims44
A locking dog assembly, comprising:
- a body including inner cavity with a lower opening;
- a first locking dog at least partially extending through a first side of the body and displaceable into and out of the inner cavity;
- a second locking dog at least partially extending through a second side of the body, opposite the first side, and displaceable into and out of the inner cavity;
- and
- a mechanism for simultaneous displacement of the first and second locking dogs with mechanical advantage.
A locking dog assembly, comprising:
- a body;
- a first housing retained in the body including a first locking dog and a first spring biasing the first locking dog in a first direction along a locking dog axis, the first housing including a first stop limiting a range of movement of the first locking dog in a second direction, opposite the first direction, along the locking dog axis;
- a second housing retained in the body including a second locking dog and a second spring biasing the second locking dog in the second direction along the locking dog axis, the second housing including a second stop limiting a range of movement of the second locking dog in the first direction;
- and
- a mechanism engaging the first locking dog via a first locking dog extension and the second locking dog via a second locking dog extension;
- wherein the mechanism simultaneously moves the first locking dog and the second locking dog along the locking dog axis.
A locking dog assembly, comprising:
- a body including an inner cavity;
- a first locking dog at least partially extending through a first opening in the body and moveable into and out of the inner cavity along a locking dog axis;
- a second locking dog at least partially extending through a second opening in the body and moveable into and out of the inner cavity along the locking dog axis;
- and
- a mechanism selectively moving each of the first and second locking dogs simultaneously.
A locking dog assembly comprising:
- a body including an inner cavity;
- a first locking dog at least partially extending through a first opening in the body and moveable into and out of the inner cavity;
- a second locking dog at least partially extending through a second opening in the body and moveable into and out of the inner cavity;
- and
- a mechanism selectively moving at least one of the first and second locking dogs into and out of the inner cavity,
- wherein the body includes first and second stops limiting a range of movement of the first and second locking dogs, respectively, out of the inner cavity.
A locking dog assembly comprising:
- a body;
- a first housing retained in the body including a first locking dog and a first spring biasing the first locking dog in a first direction;
- a second housing retained in the body including a second locking dog and a second spring biasing the second locking dog in a second direction;
- a mechanism for moving at least one of the first locking dog and the second locking dog in the first or the second direction;
- a first dowel pin removably retaining the first housing in the body;
- and
- a second dowel pin removably retaining the second housing in the body.
